Evaluasi Karakteristik Pemadatan Tanah Menggunakan Modified Proctor dengan Dua Metode Berbeda di Aceh Timur
Soil compaction is crucial in civil engineering as it affects soil shear strength, compressibility, and permeability, which determine infrastructure stability. Natural soils often have low bearing capacity, especially in clay layers, requiring thorough laboratory testing to identify appropriate compaction methods. This study compares the effectiveness of Modified Proctor tests using two procedures: Method A (No. 4 sieve) and Method C (3/4-inch sieve), applied to clay soil from Blan Nisam Village, Julok Subdistrict, East Aceh. Samples were taken from 7 points at the location with the assumption that the local soil is not homogeneous and will obtain representative data variations. Tests included Atterberg Limits, specific gravity, grain size distribution, and compaction per ASTM and SNI standards. Results classify the soil as A-6 (AASHTO) and CL (low to medium plasticity cay, USCS). Method C produced higher maximum dry unit weights which resulting a higher compaction value than Methode A. Meanwhile, Method A showed higher optimum moisture content with lower compaction value. Method C provides more large particles thus reducing the water requirement to achieve maximum density, which is the opposite of Method A testing. These findings confirm that soil compaction is highly sensitive to gradation and plasticity, impacting strength and permeability.

"Formulasi dan Evaluasi Sediaan Topikal Nanogel Mengandung Zinc Oxide Nanopartikel Ekstrak Air Kulit Buah Pinang Muda (Areca Catechu L.) dan Aktivitas sebagai Antimikroba"
Skin infections caused by Candida albicans require safe and effective natural alternative treatments. This study aims to formulate and evaluate a topical nanogel preparation containing Zinc Oxide Nanoparticles (ZnO-NP) and aqueous extract of young areca nut (Areca catechu L.) with extract concentrations of 2%, 4%, and 6%, using Carbopol 940 as the gel base. Particle size characterization using a Particle Size Analyzer (PSA) yielded results of F0 (40±2 nm), F1 (51±3.46 nm), F2 (46.6±2.88 nm), and F3 (34.6±1.15 nm), all within the nanogel range of 20–200 nm. Antifungal activity testing against Candida albicans using the well diffusion method on PDA medium yielded inhibition zones: 6% concentration (17.22 ± 0.29 mm), 4% (13.47 ± 0.31 mm), 2% (12.58 ± 0.69 mm), positive control ketoconazole (28.62 ± 0.52 mm), and negative control (0 mm). The formulation with a 6% extract concentration (F3) yielded the smallest particle size and the largest inhibition zone, equivalent to 60.17% efficacy compared to ketoconazole. In conclusion, the ZnO-NP-synthesized young areca nut peel extract nanogel has potential as an effective topical antimicrobial formulation with dose-dependent activity.

Stabilitas Lereng dengan Kombinasi Dinding Penahan Tanah (DPT) dan Tiang Pancang Berdasarkan Variasi Kedalaman Tiang
Slope stability is an important aspect in construction planning, especially in areas with weak soil conditions and high rainfall that have the potential to trigger landslides. This study aims to analyze the effect of variations in pile depth in combination with retaining walls (DPT) on increasing slope stability. The method used is numerical analysis using Plaxis software with a Mohr-Coulomb soil model based on secondary data of geotechnical parameters. The variations in pile depth described include 12 meters, 16 meters, 19 meters, and 20 meters. The results of the analysis show that the existing slope condition has a safety factor (SF) value of 1.270 and decreases to 1.064 after being given additional loads, which indicates unstable conditions. The application of DPT and pile reinforcement can significantly increase the SF value, with values ​​of 1.540 (12 m), 1.124 (16 m), 2.354 (19 m), and 2.450 (20 m), respectively. A depth of 19 meters is determined as the optimal condition because it provides a significant and efficient increase in stability. Thus, variations in pile depth have been shown to significantly impact slope stability and can be used as a reference in designing safe and economical slope reinforcement.

Interpreting Masonry Wall Cracking through Moisture-Induced Ground Movement and Soil–Structure Interaction in Fine-Grained Soils
This study investigates low rise construction located in Aceh Besar, Aceh Province – Indonesia, with shallow strip masonry foundation system exhibiting wall cracking on their wall sections. The damage is suspected caused by the shrink – swell behaviour in fine-grained moisture sensitive soil. Laboratory testing was conducted to obtain soil properties including water content, unit weight, Atteberg Limits and sieve analysis for soil gradation. Further, by using the soil mechanic framework, the analysis shows that seasonal change in moisture content leads to shrink-swell behaviour and volumetric change. The volumetric change was spatially non-uniform causing differential local movement in the supporting ground beneath foundation. The observed crack patterns are in agreement with this local ground settlement inducing tensile stress in masonry infill wall due to this differential movement of ground support. The findings reflect that even soil with moderate plasticity and activity can caused significant structural stress upon subjected to drying-wetting cycle. The study also indicates that the main cause of this damage is the incompatibility between supporting ground with the above rigid body of structure due to non-uniformity volumetric change in supporting ground induced by shrink-swell behaviour of soil. In general, several essential things to highlight for this study are environmental condition change, soil behaviour and structural response/soil structure interaction in low rise construction with shallow foundation system.

Hubungan Body Image dan Pengetahuan Gizi dengan Konsumsi Fattening Foods pada Siswa SMA di Surakarta
Adolescence is a vulnerable period in the formation of eating behaviors, where body image and nutritional knowledge can affect the tendency to consume fattening foods. This study aims to determine the relationship between body image and nutritional knowledge with the consumption of fattening foods in high school students in the city of Surakarta. This study used an observational quantitative design with a cross-sectional approach on 174 respondents who were selected using multistage random sampling and proportional random sampling techniques. Data were collected using body image questionnaires (MBSRQ-AS), nutrition knowledge questionnaires, and SQ-FFQ, then analyzed using the Spearman Rank test. The results showed that most of the respondents had a negative body image (51.72%), good nutrition knowledge (84.49%), and consumption of fattening foods in the category of excess intake (63.8%). There was no relationship between body image and fattening food consumption (p=0.126), but there was a relationship between nutritional knowledge and fattening food consumption (p=0.034; r=-0.161), which shows that the better the nutritional knowledge, the lower the consumption of fattening foods. Thus, improving nutrition education is important to support the formation of healthier consumption behaviors in adolescents.

Hubungan Persentase Kesesuaian Asupan Makronutrien dengan Status Gizi pada Remaja SMA di Surakarta
Adolescent nutrition problems are still a concern due to the imbalance between nutrient intake and needs during a period of rapid growth. This study aims to analyze the relationship between the percentage of conformity of macronutrient intake with nutritional status in high school adolescents in Surakarta based on energy distribution. This study is an observational study with a cross-sectional design involving 221 respondents selected through a proportional random sampling technique. Macronutrient intake data was collected using 3x24-hour food recall and analyzed with NutriSurvey 2007, while nutritional status was determined based on BMI by age (BMI/U) using WHO AnthroPlus. Data analysis was carried out using the Chi-Square test with a significance level of p<0.05. The results showed that most of the respondents had normal nutritional status (72.9%). The percentage of appropriate protein intake was significantly associated with nutritional status (p=0.037), while the percentage of appropriate fat (p=0.111) and carbohydrate (p=0.911) intakes did not show a significant relationship. This demonstrates the importance of appropriate amino acid intake for somatic growth and indicates that adolescents have metabolic flexibility in regulating energy sources. Future researchers are advised to expand the scope of variables to include physical activity, snacking behavior, and social factors.

Analisis Kandungan Zat Gizi Makro dan Daya Terima Bakso Ikan Kembung Substitusi Tepung Kacang Hijau dengan Penambahan Wortel dan Bayam
Pregnant women with Chronic Energy Deficiency (CED) continue to be a public health concern in Indonesia. According to the 2023 Indonesian Health Survey (SKI), 16.9% of pregnant women had CED, which raises their risk of anemia, impaired fetal growth, and low birth weight. One strategy to deal with this problem is by creating functional foods based on local ingredients that are nutritious and acceptable. The aim of this investigation was to examine the macronutrient content and acceptability of mackerel fish meatballs substituted with mung bean flour and enriched with carrots and spinach as a healthy substitute food for expectant mothers with CED. This study used a pre-experimen design with a post-test design consisting of three formulations: F1 (80:20), F2 (50:50), and F3 (20:80). Acceptability testing was conducted on 40 semi-trained panelists using a hedonic test on color, aroma, texture, and taste, and examined using the Kruskal–Wallis test. There were no discernible variations in the outcomes (p>0.05), although F3 was the most preferred formulation. Macronutrient analysis showed that the selected formula contained 116.9 kcal of energy, 10.25% protein, 0.18% fat, and 18.57% carbohydrates. This product has the potential as a functional food to support nutritional improvement in pregnant women with CED.

Evaluasi Kesesuaian Standar Pelayanan Minimum (SPM) Terminal Penumpang di Kalimantan Selatan
This study aims to evaluate the level of compliance with the Minimum Service Standards (SPM) at Gambut Barakat Terminal, Km 6 Banjarmasin Terminal, and H. Soemarsono Tanah Laut Terminal based on the Regulation of the Minister of Transportation Number 40 of 2015 concerning Minimum Service Standards for Passenger Terminals. This research employed a descriptive evaluative method by assessing the conformity level of facilities and services at each terminal. Data were collected through field observations and documentation based on SPM indicators, including safety, security, reliability or regularity, comfort, accessibility, and equality aspects. The assessment was conducted using a scoring system to determine the level of service fulfillment at each terminal. The results indicate that the implementation of SPM at the three terminals is still uneven. Km 6 Banjarmasin Terminal showed a higher level of service fulfillment compared to the other terminals, while H. Soemarsono Tanah Laut Terminal had the lowest fulfillment level, particularly in safety and equality aspects. The correlation test results revealed a strong positive relationship between terminal classification and the level of SPM fulfillment, indicating that terminals with higher classifications tend to provide more complete facilities and better services. The low level of SPM fulfillment at several terminals is influenced by limited facilities, operational management, and the suboptimal implementation of service standards. The findings of this study are expected to serve as evaluation material for improving the quality of passenger terminal services in South Kalimantan.

Aktivitas Antibakteri Ekstrak Daun Bidara (Ziziphus mauritiana) terhadap Pertumbuhan Staphylococcus aureus pada Isolat Ulkus Diabetikum
Diabetes mellitus is a long term metabolic disease that may trigger various complications, including diabetic ulcers. These ulcers are highly vulnerable to bacterial infection, especially by Staphylococcus aureus, which can delay wound healing and worsen the patient’s condition. This study was conducted to determine the antibacterial activity of ethanol extract of bidara leaves (Ziziphus mauritiana L.) against Staphylococcus aureus isolated from diabetic ulcer wounds. The research employed an experimental laboratory design using the well diffusion technique on Mueller Hinton Agar media. Bidara leaf extract was tested at concentrations of 5%, 10%, and 15%. Chloramphenicol was applied as the positive control, while DMSO and distilled water were used as negative and neutral controls. Antibacterial effectiveness was assessed based on the diameter of the inhibition zone formed around each well. The findings demonstrated that the ethanol extract of bidara leaves was able to inhibit the growth of Staphylococcus aureus at all tested concentrations. The strongest inhibitory effect was observed at the 15% concentration. Statistical evaluation using one way ANOVA revealed a significant difference between treatment groups (p<0.05). The antibacterial activity is thought to be associated with the presence of bioactive compounds, including flavonoids, alkaloids, tannins, and saponins, which may interfere with bacterial cell function and growth. In summary, ethanol extract of bidara leaves shows promising potential as a natural antibacterial agent against Staphylococcus aureus isolated from diabetic ulcers.

Hubungan Sikap dalam Pencegahan Anemia dengan Status Anemia pada Remaja Putri di SMAN 1 Kartasura
The results of the 2024 survey on young girls at SMAN 1 Kartasura showed that 28,03% of young girls had anemia. There are quite a lot of aspect that cause anemia, one of them refers to the attitude of students towards adherence with the consumption of blood tablets. The research goals to analyze the connection amid attitudes in the prevention of anemia also the status of anemia in adolescent girls at SMAN 1 Kartasura, Sukoharjo Regency. One of them has to do withThis utilized a cross-sectional, quantitative design. Utilizing the simple random sampling method, 83 female students made up the research sample. Data gathering was done through filling out a questionnaire to measure the respondent's attitude as well as checking hemoglobin levels using the Cyanmethemoglobin method. The attitude category is determined based on the median value, namely positive attitude (≥70,00) and negative (<70,00), while anemia status is classified into anemia (<12 g/dL) and non anemia (≥12 g/dL). According to the study's findings, 54.2% of respondents had a favourable attitude about anaemia prevention. 66.3% of people with an optimistic outlook do not suffer from anaemia. Attitude and anaemia status did not significantly correlate, according to the Chi-Square test (p=0,310). This indicates that attitude is not a aspect that directly impacts the status of anemia, because there are still other aspect that directly impact hemoglobin levels, namely the intake of nutrients both from food and supplements, tablets with blood or other supplements.

Formulasi dan Evaluasi Sediaan Topikal Nanogel Daun Kipahit (Tithonia diversifolia) dan aktivitas sebagai Antimikroba
Candida albicans is a fungal microorganism that can cause candidiasis and requires the development of alternative therapies derived from natural products. Bitter leaf (Tithonia diversifolia) contains bioactive compounds such as flavonoids, alkaloids, and tannins that have potential antifungal activity. This study aimed to formulate and evaluate a nanogel containing ethanol extract of Tithonia diversifolia leaves and to assess its antifungal activity against Candida albicans. The extract was obtained through maceration using 70% ethanol and formulated into nanogels using a modified emulsification-diffusion method at concentrations of 5%, 10%, and 15%. The formulations were evaluated for organoleptic properties, homogeneity, pH, spreadability, viscosity, particle size, and antifungal activity using the agar well diffusion method. The results showed that all nanogel formulations exhibited good physical characteristics and met the requirements for topical application. Particle size analysis revealed sizes ranging from 755.75 to 847.29 nm, indicating that all formulations met the criteria for nanoparticulate systems. All formulations demonstrated inhibitory activity against the growth of Candida albicans, with inhibition tending to increase as the extract concentration increased. The incorporation of bitter leaf extract into a nanogel system may improve the stability and delivery of bioactive compounds compared with conventional formulations. Therefore, the ethanol extract nanogel of Tithonia diversifolia leaves has the potential to be developed as a natural-based topical antifungal formulation.

Analisis Hidrograf Satuan Sintetik Limantara Berdasarkan Karakteristik Morfometri di DAS Klawoguk
This study aims to analyze the characteristics of the Limantara Synthetic Unit Hydrograph (SUH) based on morphometric parameters in the Klawoguk Watershed. Watershed morphometric parameters were extrated from Digital Elevation Model (DEM) and river network maps using Geographic Information System. The time lag (Tg), rainfall time (Tr), time to peak (Tp), and peak discharge (Qp) values ​​in each sub-watershed were determined as input for the Limantara SUH. The results showed that the morphometric characteristics of the Klawoguk Watershed have an influence on the Limantara SUH. The variability in watershed area, the length of the main river, the length of the river to the center of gravity of the watershed, and the slope of the river cause differences in the values ​​of Tg, Tr, Tp, and Qp. Sub-watershed 5 has the highest peak discharge of 0,558 m³/s and a peak time of 1,308 hours while the sub-watershed 2 has the lowest peak discharge of 0,231 m³/s. The hydrographs of all sub-watersheds also show a rapid increase in discharge (rising limb) and a slower decrease in discharge (recession limb), indicating a greater influence of surface runoff than infiltration. The larger the watershed area and the length of the main river, the resulting hydrograph has a longer recession time with a higher peak discharge value. Conversely, a steeper river slope results in a faster flow response. This indicates that the Limantara HSS method describes the characteristics of the watershed's hydrological response based on morphometric parameters.

Hubungan Antara Tingkat Aktivitas Fisik Harian dengan Status Gizi pada Remaja di SMA Batik 1 Surakarta
Nutritional problems among adolescents, such as undernutrition, overnutrition, and obesity, remain public health challenges that require attention. According to the 2018 Riskesdas survey, the prevalence of overnutrition among adolescents aged 16–18 years reached 9.5%, with physical activity being one of the factors that play a role in maintaining the body’s energy balance. This study aims to analyze the relationship between daily physical activity levels and nutritional status among adolescents at Batik 1 High School in Surakarta. The theoretical framework used includes the concept of adolescent nutritional status based on the Age-Adjusted Body Mass Index (BMI/A) as well as Brown’s (2005) modified theoretical framework. This study employed an analytical observational design with a cross-sectional approach. The study sample consisted of 62 11th-grade students selected using simple random sampling. Nutritional status data were obtained through anthropometric measurements, while physical activity levels were assessed using the Physical Activity Questionnaire for Adolescents (PAQ-A). The results showed that the majority of respondents had an overnutrition status (50%) and moderate physical activity levels (50%). Analysis using Spearman’s rank correlation test yielded a p-value of 0.188 (p > 0.05), indicating no significant association between physical activity and nutritional status. These findings suggest that adolescents’ nutritional status is influenced by various factors other than physical activity, such as dietary patterns, energy intake, and lifestyle behaviors.

Analisis Komparatif Algoritma Paparan Media Sosial dan Pola Kebiasaan Sarapan terhadap Status Gizi Remaja
This study aims to examine the relationship between the intensity of social media use and breakfast habits on the nutritional status of adolescents at SMP Negeri 6 Surakarta. The methodology employed was a cross-sectional design with a quantitative orientation and included 92 participants recruited using non-probability sampling techniques. Data collection regarding social media use was conducted using a validated questionnaire (Cronbach’s Alpha = 0.914), while breakfast habits were assessed using a 24-hour recall method over a one-week period, and nutritional status was evaluated using the Age-Adjusted Body Mass Index (BMI/A). Data analysis was conducted using the Chi-Square test. The study findings revealed that the majority of participants (82.6%) fell into the category of optimal social media use, 76.1% had breakfast habits that met their energy needs, and 53.3% had a normal nutritional status. However, 32.6% of participants showed signs of overnutrition and 6.5% were obese. The statistical test results indicated no significant association between social media use and nutritional status (p=0.817), nor was there an association between breakfast habits—as assessed by energy (p=0.421), protein (p=0.628), fat (p=0.672), and carbohydrate (p=0.496) intake—and nutritional status. It can be concluded that adolescents’ nutritional status is not solely influenced by social media use or breakfast habits, but rather results from the accumulation of various factors such as the overall quality of daily dietary patterns, physical activity levels, and family socioeconomic conditions.

Pengaruh Pemadatan dan Substitusi Bubur Kertas terhadap Kuat Tekan Batako Ringan Struktural Dinding
This study analyzes the impact of compaction levels and paper pulp ratios on the compressive strength of papercrete blocks. The objective is to develop a lightweight building material that meets structural strength standards based on SNI 03-0348-1989. The base formulation combines cement and sand in a 1:3 ratio, with the sand volume substituted by paper at variations of 80%, 90%, and 100%. Density engineering was conducted by compressing the initial mixture volumes of 120%, 130%, 140%, and 150% into a standard size of 5 cm x 10 cm x 20 cm. Mechanical performance testing involved single blocks, paired blocks bonded with a 1 cm mortar joint, and conventional red bricks as a control comparison. Experimental results demonstrate that most papercrete variants qualify as structural materials within classes II, III, and IV. Only the 120PB100 sample failed to meet the standard classification. Interestingly, the standard red brick did not qualify for any strength class under the SNI framework. The highest mechanical performance was achieved by the 140PB80 variant, yielding a single-block compressive strength of 70.139 kg/cm². However, when evaluated in a paired formation, the strength of this 140PB80 sample reduced by 29.87% to 49.190 kg/cm².

Analisis Variabilitas Iklim dan Tren Produktivitas Kelapa Sawit pada Berbagai Zona di Indonesia
Climate change poses a significant challenge to the sustainability of palm oil production in Indonesia through changes in rainfall and temperature patterns. This study aims to analyze changes in climate variability and trends in palm oil productivity across various climate zones in Indonesia from 1990 to 2023. The study area encompasses palm oil-producing provinces, grouped into equatorial and monsoon zones based on the BMKG classification. Climate data, including minimum, maximum, and average temperatures, and rainfall, were obtained from NASA Power, while palm oil productivity data were obtained from the Agricultural Statistics Database. The analysis used the Mann-Kendall and Sen's Slope tests to identify the direction and magnitude of change trends, and the Mann-Whitney test to compare climate variability across observation periods. The results show an increasing trend in rainfall and temperature across the study area, indicating wetting and warming phenomena. The equatorial zone has more stable agroclimatic conditions and higher productivity than the monsoon zone. Conversely, the monsoon region experiences thermal stress and higher rainfall fluctuations, potentially reducing productivity. These findings demonstrate the importance of climate adaptation strategies based on agroclimatic zone characteristics to maintain the sustainability of palm oil production in Indonesia.

Analisis Kualitas Udara dalam Ruang dengan Gangguan Fungsi Paru pada Siswa MAN 1 Aceh Besar
Indoor air pollution in schools often shows high PM2.5 concentrations, primarily due to outdoor air infiltration and dust suspended by student activities. This study aims to analyze the relationship between indoor air quality and lung function impairment among students at MAN 1 Aceh Besar, located in an area with high vehicle density. Using a descriptive-analytical design with a cross-sectional approach, the study involved 78 students selected through proportional random sampling. Results showed that 17.9% of students experienced lung function impairment. PM2.5 concentrations in 65.4% of classrooms were found to exceed the threshold limit value (TLV) of 25 µg/m³, although statistically, it did not show a significant relationship with lung function impairment (p=0.07). However, students in rooms with high PM2.5 levels were 3.8 times more likely to experience impairment compared to those in rooms with PM2.5 levels below the TLV. Physical factors such as temperature (74.4% abnormal) and humidity (50% abnormal) also showed no statistically significant relationship with the students' lung function. Conversely, a significant relationship was found between smoking habits and lung function impairment (p=0.008), where students who smoke are 4.8 times more likely to experience lung function impairment. In conclusion, smoking habits are a risk factor that can increase PM2.5 concentration, damage the respiratory tract, and trigger lung function impairment in students.

Ketersediaan dan Kelayakan Alat Laboratorium dalam Mendukung Penerapan K3 di Sekolah SMAN X Jakarta
Biology laboratories play a crucial role in science education at high schools, but the availability of equipment and the implementation of Occupational Safety and Health (OSH) standards are still not fully optimized. This study aims to identify the availability, suitability of equipment, and compliance of facilities with OSH standards at SMAN X Jakarta. A descriptive qualitative method was applied through observation, interviews with biology teachers and lab assistants, and documentation. The results show that equipment availability reached 72.2% (good category) and all equipment was in good condition. The storage system is neatly organized with proper labeling. The available OSH facilities (fire extinguishers, first aid kits, PPE, ventilation, alarms, and signs) functioned well; however, the availability rate of OSH facilities was only 54.5% (adequate category) because evacuation routes, emergency exits, and eyewash stations were not yet available. The implementation of OSH is sufficiently adequate, with safety instructions and the use of PPE by students. The availability of appropriate equipment and the proper implementation of OSH are crucial for supporting safe and efficient laboratory practice. The study recommends the addition of emergency facilities, increased periodic supervision, and routine maintenance of laboratory equipment to support the quality of biology education and the safety of all laboratory users.

Analisis Perbedaan Asupan Makro dan Mikro Nutrisi Sarapan terhadap Makan Siang Mahasiswa Poltekkes Aceh 2024
Breakfast plays an important role in supporting students’ daily activities as it serves as the primary source of energy for both the body and brain. A carbohydrate-rich breakfast can help maintain blood glucose levels, improve concentration, and enhance focus and productivity during learning activities. In contrast, skipping breakfast may lead to decreased energy, impaired concentration, and fatigue, which can negatively affect academic performance. This study aimed to analyze differences in total breakfast macronutrient and micronutrient intake and their effects on lunch consumption among students at Aceh Health Polytechnic. A true experimental approach with a Cluster Randomized Controlled Trial (CRCT) design was employed involving 32 students selected through universal sampling. Data were collected using questionnaires from August 30 to September 12, 2024, and analyzed using paired t-test, One-Way ANOVA, and non-parametric alternatives when assumptions were not met, using STATA software. The results showed no significant differences in any of the variables examined among the 6373 group, the 7383 group, and the control group (p > 0.05). Although differences in mean nutrient intake were observed, these differences were not statistically significant, while fat intake showed a tendency toward significance (p = 0.098). The intervention did not significantly affect either macronutrient or micronutrient intake. Future studies are recommended to involve larger sample sizes, longer intervention periods, and improved dietary intake monitoring to obtain more accurate results.

Analisis Efektivitas Metode FMEA dalam Pengendalian Kualitas Proses Produksi Untuk Mengurangi Produk Cacat pada PT. XYZ
Quality control in manufacturing industries cannot be separated from the interaction between workers, machines, and work procedures, since most production failures stem not only from technical malfunctions but also from the dynamics of the socio-technical system as a whole. PT. XYZ, a paint manufacturing company in Bekasi, West Java, continues to face persistent defective product problems. Based on production data from January to October 2025, the number of defective products reached 625 units, representing 4.84% of total production of 12,977 units, which far exceeds the company's maximum tolerance standard of 2% per year. The two most dominant types of defects identified are color inconsistency with the established standard and the formation of bubbles on the paint product surface. This study aims to identify the types and causes of defective products, determine the most dominant risk factors, and formulate systematic improvement proposals. The Failure Mode and Effect Analysis (FMEA) method was applied to prioritize risks based on the Risk Priority Number (RPN), supported by the Pareto Diagram, Fishbone Diagram, and 5W+1H analysis. The results show that three causes were classified as critical, all exceeding the average RPN of 199.5: human error (RPN = 240), non-standard raw materials (RPN = 216), and poor product viscosity (RPN = 210). Improvement recommendations include routine operator training, consistent SOP enforcement, tighter raw material inspection, regular machine calibration, and strengthening inter-divisional communication between Warehouse, Quality Control, and Production divisions to reduce the defect rate below the 2% company standard.

Klasifikasi Tingkat Kelunturan Warna Kain Menggunakan KNN, SVM, dan Random Forest
The laundry industry faces challenges in maintaining service quality, particularly regarding fabric color fading after washing. Assessments that are still performed manually tend to be subjective and inconsistent, so a more objective automated classification system is required. This study aims to apply and compare three algorithms, namely KNN, SVM, and Random Forest, to classify the level of fabric color fading based on digital images. The features used comprise color in the RGB and HSV spaces as well as shape in the form of area and shape ratio, all extracted automatically. A total of 300 images were divided into 250 training data and 50 testing data, then mapped into three categories, namely not faded, fairly faded, and faded. The testing results show that Random Forest delivers the best performance with an accuracy of 0.96, followed by SVM at 0.94 and KNN at 0.88. All models faced difficulties in recognizing the minority class due to data imbalance. This study proves that the machine learning approach, particularly Random Forest, is able to assess color fading levels more accurately and consistently than manual evaluation, while supporting quality control in the laundry industry.

Analisis Kapasitas Saluran Drainase terhadap Debit Rencana di Kelurahan Bidara Cina, Kecamatan Jatinegara, Jakarta Timur
Bidara Cina is a flood-prone area in East Jakarta due to high rainfall, limited channel capacity, and low elevation along the Ciliwung River. This study analyzes the existing drainage channels' capacity to accommodate design runoff discharge based on BMKG rainfall data and hydrological parameters. Methods include calculating design rainfall intensity (Gumbel/Mononobe method), design discharge (Rational Method), and existing capacity (Manning’s formula) using secondary data from BMKG, BIG, BPS, and East Jakarta Water Resources Sub-department. Main channel segments were selected as representative samples. Based on frequency analysis of 20-year extreme data (2006–2025) from Halim Perdanakusuma Station, the design rainfall intensity is 78.71 mm/hour for a 5-year return period and 96.60 mm/hour for a 10-year return period. Evaluation of 15 channel segments shows that macro channels (Ciliwung River and Ciliwung Waterway) and the main connecting channel (West Otista Raya Street) meet the required capacity. However, 7 secondary channel segments in densely populated areas (RW 06, RW 07, and RW 11) fail to meet capacity or overflow due to narrow dimensions and the lack of local retention polders.
