Aktivitas Antibakteri Emulgel dan Uji Sifat Fisik Ekstrak Etanol Daun Sumambu terhadap Escherichia coli FNCC 0091
Sumambu leaves (Hyptis capitata Jacq.) can be utilized as a traditional medicinal remedy. However, the direct application of sumambu leaves on the skin is impractical and uncomfortable, so they are formulated into an emulgel dosage form. This study aims to evaluate the physical properties and antibacterial activity of sumambu leaves. This research is an experimental study. The test material was sumambu leaf powder, which was extracted using the maceration method with 96% ethanol as the solvent. The concentrated extract was then formulated into an emulgel and tested for its physical properties, including organoleptic characteristics, spreadability, adhesiveness, and pH. Antibacterial activity against Escherichia coli was tested using the well diffusion method. The antibacterial activity was indicated by the presence of inhibition zones in emulgels with concentrations of 5%, 10%, and 15%. The analysis used in this study was descriptive analysis. The results of the physical property tests showed that the emulgel of sumambu extract had good organoleptic properties, adhesiveness, and pH. However, its spreadability did not meet the standard criteria, as the required spread diameter for a good emulgel preparation is 5–7 cm. The antibacterial activity test results showed that the emulgel of sumambu leaf extract exhibited antibacterial activity against Escherichia coli at concentrations of 5%, 10%, and 15%, with average inhibition zone values of 18 mm, 22 mm, and 26 mm, respectively. These results indicate that the emulgel of sumambu leaf extract possesses antibacterial activity against Escherichia coli FNCC0091.

Penurunan Fungsi Saraf Olfaktorius (CN1) pada Mencit (Mus musculus) Akibat Induksi Natrium Siklamat Berlebih
The use of sodium cyclamate, an artificial sweetener, as an additive in food and beverage production is commonly found among vendors around schools and campuses. Artificial sweeteners such as sodium cyclamate are often used as substitutes for sugar to reduce production costs. Although its dosage has been regulated by government and health authorities, these regulations are frequently ignored by vendors who prioritize profit without considering product quality and nutritional value. Excessive use of artificial sweeteners, particularly sodium cyclamate, can have harmful health effects. Several studies indicate that excessive consumption may damage nerve cells. Therefore, this study aims to determine the effect of excessive sodium cyclamate consumption on the decline of olfactory nerve function (CN I) in mice (Mus musculus). The dosage used was adjusted according to BPOM regulations for humans, which is 11 mg/kg body weight, then converted for mice using the Laurence conversion table. Twelve male Swiss Webster mice were divided into four groups: a control group and three treatment groups (P1: 0.55 mg/kg BW, P2: 1.1 mg/kg BW, P3: 1.65 mg/kg BW), each consisting of three mice. Sodium cyclamate was administered for 25 days to ensure systemic exposure. An ammonia scent test was then conducted to assess olfactory nerve function decline. The results showed that higher doses were associated with greater reduction in ammonia detection ability, indicating decreased olfactory nerve function (CN I).

Faktor-Faktor yang Berhubungan dengan Kualitas Hidup Penderita Diabetes Melitus Tipe 2 Usia Produktif di Puskesmas Meuraxa Banda Aceh 2025
As a chronic pathology, diabetes mellitus (DM) exhibits a surging prevalence that severely deteriorates the well-being and quality of life of affected individuals. This investigation sought to analyze the specific determinants influencing the quality of life among productive-age individuals (ranging from 15 to 64 years) diagnosed with type 2 DM within the administrative territory of the Meuraxa Public Health Center, Banda Aceh, in 2025. Professionally, this research integrated a descriptive analytic framework utilizing a cross-sectional design. From a total population of 391 type 2 DM patients, a cohort of 80 participants was selected via an accidental sampling strategy. Empirical data were gathered through structured questionnaire-guided interviews and subsequently processed using univariate and bivariate statistical evaluations within the SPSS software environment. The descriptive univariate assessments indicated that a vast majority of the subjects experienced a moderate quality of life (80.0%). Regarding independent variables, 45.0% demonstrated negative attitudes, 26.3% possessed deficient knowledge, 50.0% had a long-standing disease duration, 48.8% reported a history of medication-induced adverse effects, and 51.3% presented with a history of diabetic ulcerations or wounds. Furthermore, the inferential bivariate modeling demonstrated a statistically significant correlation between quality of life and three major indicators: patient attitude (p = 0.003), health literacy or knowledge (p = 0.015), and wound history (p = 0.048). Conversely, no significant associations were observed for illness duration (p = 0.090) or the experience of pharmaceutical side effects (p = 0.317). To conclude, personal attitude, cognitive knowledge, and clinical wound history stand as pivotal elements dictating the quality of life in working-age type 2 DM patients. Consequently, systematic health counseling and targeted complication mitigation strategies must be intensified to optimize patient well-being.

Pengaruh Substitusi Tepung Daun Kelor (Moringa Oleifera) Terhadap Kadar Serat dan Tekstur Produk Snack Bar
The inadequate dietary fiber intake among the Indonesian population contributes to an increased risk of degenerative diseases, including diabetes mellitus. The utilization of Moringa oleifera L. as a functional food ingredient has attracted considerable attention due to its relatively high fiber content and its potential to enhance the nutritional quality of ready-to-eat food products. This study aimed to investigate changes in dietary fiber content and the textural characteristics of snack bars formulated with different levels of moringa leaf flour incorporation. An experimental approach employing a Completely Randomized Design (CRD) was applied, consisting of four treatment formulations with moringa leaf flour substitution levels of 0%, 5%, 10%, and 15%, each conducted in duplicate. Dietary fiber content was determined using the AOAC enzymatic-gravimetric method, while textural properties were evaluated using a Texture Analyzer. Statistical analysis was performed using One-Way ANOVA followed by Duncan’s Multiple Range Test (DMRT) to identify differences among treatments. The findings demonstrated that increasing the proportion of moringa leaf flour significantly affected both dietary fiber content and the texture of the snack bars (p < 0,05), with fiber levels increasing from 2,51% to 6,87%. The 15% formulation met the criteria for a high-fiber food product, whereas the 5% and 10% formulations were classified as sources of dietary fiber. These results highlight the potential of moringa leaf flour as a valuable ingredient for the development of highly functional snack bar products.

Hubungan Frekuensi Konsumsi Minuman Teh Kemasan dengan Status Gizi Remaja di SMKN 1 Purwokerto
Adolescence is a period of rapid growth that requires optimal nutritional intake. However, changes in lifestyle and consumption patterns among adolescents often lead to a habit of consuming sugar-sweetened beverages, including packaged tea that contains relatively high amounts of sugar. Excessive sugar consumption can increase daily energy intake and potentially lead to nutritional problems, particularly overweight and obesity. This study aims to determine the relationship between the frequency of packaged tea consumption and the nutritional status of adolescents at SMKN 1 Purwokerto. This study employed an analytical observational design with a cross-sectional approach. The study population consisted of all 179 10th-grade AKL students at SMKN 1 Purwokerto, with a sample of 123 students selected using proportionate random sampling. Data on the frequency of packaged tea consumption were collected using a Food Frequency Questionnaire (FFQ), while nutritional status data were obtained through measurements of weight and height, which were then analyzed using the BMI/U indicator based on z-scores. The data were subsequently analyzed to test the relationship between the two variables using the Chi-Square correlation test. The results of the study showed no association between the consumption of packaged tea beverages and the nutritional status of adolescents (p-value = 0.204; p > 0.05). Thus, the consumption of packaged tea beverages does not affect nutritional status.

Perencanaan Sistem Pengelolaan Kualitas Lingkungan dan Pengendalian Polutan Berkelanjutan untuk Pengembangan Ekowisata Taman Wisata Landak
Landak Tourism Park is a post-mining area with potential for ecotourism development, but water-quality degradation may constrain its environmental sustainability. This study evaluates the factors affecting environmental-quality management, compares two surface-water sources, develops a conceptual clean-water treatment train, and formulates integrated pollution-control strategies. A descriptive-comparative mixed-methods design was used, combining water-quality testing of a tributary and a post-mining lake with field observation and in-depth interviews with site managers. Compliance was assessed against Class II surface-water criteria in Government Regulation of the Republic of Indonesia No. 22/2021. The tributary showed severe suspended-solids and organic pollution, with TSS of 732 mg/L, BOD of 10.3 mg/L, COD of 120 mg/L, ammonia of 0.53 mg/L, and DO of 2.70 mg/L. The lake had substantially lower TSS (6.67 mg/L), turbidity (4.91 NTU), and ammonia (<0.0089 mg/L), although BOD (7.62 mg/L), COD (64.7 mg/L), and DO (3.20 mg/L) still did not meet Class II criteria. The lake is therefore the more feasible source for further treatment. A conceptual process comprising screening, pre-sedimentation, coagulation-flocculation, sedimentation, multimedia filtration, and disinfection is proposed, supported by source protection, erosion control, wastewater management, routine monitoring, and institutional strengthening. The design must be verified through jar tests, pilot testing, and site-specific design-flow data before implementation.

Sistem Pendukung Keputusan Berbasis IoT untuk Monitoring Kinerja Panel Surya dan Pemeliharaan Prediktif
Solar energy is a critical component of renewable energy strategies; however, photovoltaic (PV) system performance is frequently degraded by environmental factors such as dust accumulation, shading, and component failures. These issues lead to reduced energy yield and increased operational costs. This research develops an IoT-based decision support system (DSS) for real-time performance monitoring and predictive maintenance scheduling of solar panels. The system integrates sensor data on voltage, current, irradiance, and temperature, transmitted via a wireless network to a cloud-based analytics platform. A fuzzy logic algorithm evaluates panel health and triggers maintenance recommendations when performance deviations exceed pre-defined thresholds. The system was tested under simulated real-world conditions. Results demonstrate that the proposed DSS effectively detects performance degradation due to soiling and module-level faults, achieving a detection accuracy of 94% as indicated by the correlation coefficient between predicted and actual maintenance urgency, enabling timely maintenance interventions. This approach contributes to the field of intelligent renewable energy monitoring by providing a reliable, data-driven tool that reduces unnecessary maintenance costs and maximizes the operational lifespan of PV installations.

The School Health Program (Usaha Kesehatan Sekolah/UKS) plays a strategic role in promoting healthy behaviors among students, including adequate water consumption. However, its implementation has not fully succeeded in establishing consistent drinking habits. This study aimed to evaluate the implementation of the School Health Program in relation to the adequacy of water consumption among fifth-grade students at SD Muhammadiyah 2 Surakarta. A descriptive study with a mixed-methods approach was employed. Participants included students, teachers, and school stakeholders. Data were collected through observation, interviews, and measurement of water intake based on individual fluid requirements adjusted for body weight. Data were analyzed using descriptive quantitative and qualitative approaches. The findings revealed that 85% of students achieved adequate water intake, while 15% were categorized as inadequate. Despite this, the program implementation was not optimal, as indicated by the absence of structured habituation, lack of continuous monitoring, and limited teacher involvement in shaping drinking behaviors In conclusion, although most students met their fluid requirements, the School Health Program has not been effective in fostering consistent water consumption behavior. Strengthening behavioral-based interventions is essential to improve program effectiveness.

Analisis Spasial Kepadatan Penduduk dengan Penyebaran Demam Berdarah Dengue (DBD) di Wilayah Kota Banda Aceh
Dengue Hemorphic Fever (DHF) remains a significant public health challenge in Banda Aceh City, characterized by fluctuating annual case trends. Population density is heavily suspected of influencing transmission risk due to intense human interaction and vector presence. This ecological study aims to analyze the relationship between population density and DHF incidence, while identifying spatial distribution patterns and case clusters in Banda Aceh City from 2021 to 2025. Employing a quantitative descriptive-analytic design based on Geographic Information System (GIS), aggregate secondary data were analyzed using QGIS 3.34.11, SaTScan, GeoDa, and Google Earth software. The results revealed a total accumulation of 1,330 DHF cases, with the highest prevalence observed in males and the child-to-adolescent age groups. Statistical testing demonstrated no significant relationship between population density and DHF incidence (p-value > 0.05). However, spatial analysis confirmed the existence of dynamic annual case clustering, with several sub-districts identified as high-risk areas. In conclusion, although population density is not directly correlated, the distribution of DHF cases in Banda Aceh exhibits a distinct spatial clustering pattern. Consequently, DHF control efforts must be specifically targeted at high-risk cluster areas through a location-based intervention approach.

Expert System for Electric Vehicle Charging Infrastructure Planning: A Scenario-Based Decision Support Framework for Two-Wheeler and Bus Fleets
The rapid adoption of electric vehicles (EVs) presents significant challenges in charging infrastructure planning, particularly for diverse vehicle fleets in developing regions. This study proposes an expert system-based decision support framework for EV charging infrastructure planning, specifically addressing two-wheeler and bus fleet scenarios. The framework integrates scenario-based demand characterization with rule-based inference to provide location recommendations and capacity planning decisions. Using data from Indonesian urban transportation contexts, the expert system evaluates multiple criteria including demand patterns, infrastructure availability, and energy consumption profiles. Results indicate that the proposed framework successfully identifies optimal charging locations with 87.5% accuracy compared to expert validation, while reducing planning time by approximately 40% compared to conventional methods. The system provides decision-makers with actionable recommendations for prioritizing infrastructure investments across different fleet types. This research contributes to the growing body of knowledge on AI-based decision support systems for sustainable transportation infrastructure, with implications for policy formulation and urban planning in developing economies.

Karakteristik Farmakognostik Berdasarkan Sifat Fisis dan Parameter Non Spesifik Ekstrak Daun Burasse (Phaseolus lunatus L.)
Burasse leaves (BL) are utilized by the community of Enrekang Regency as both a traditional fever remedy and a food source. This study aimed to determine the physical pharmacognostic characteristics and non-specific parameters of Burasse leaf extract from Enrekang (BLEE) as a raw material for natural medicine (RMNM). This experimental research involved preparing dried powder leaves, macerating it with 70% ethanol, and evaluating its physical pharmacognostic characteristics (PPC). The PPC evaluation included macroscopic and organoleptic identification of both the simplisia and the extract, alongside non-specific parameter (NSP) assays for moisture content (MC), total ash content (TAC), and acid-insoluble ash content (AIAC). Results showed that the dried simplisia leaves were triangular or ovate-lanceolate, 7–15 cm long, 5–9 cm wide, with entire margins, brownish-green color, and were odorless and tasteless. The extract was thick and viscous, blackish-brown, odorless, and tasteless. The NSP values were: MC = 2.183 ± 0.002%, TAC = 6.475 ± 0.001%, and AIAC = 1.065 ± 3.511%. In conclusion, these findings can serve as a quality standard reference for BLEE in developing natural medicine formulations.

Pengaruh Penambahan Kapur Barus pada Bahan Bakar Bensin terhadap Prestasi dan Emisi Mesin Bensin
This study aims to analyze the effect of adding camphor or naphthalene to gasoline on the performance and exhaust emissions of a gasoline engine. An experimental method was applied using a single-cylinder, four-stroke Enduro XL gasoline engine with camphor concentrations of 0%, 5%, 10%, 20%, and 30%. Tests were conducted at engine speeds of 1,200, 1,400, 1,600, 1,800, and 2,000 rpm. The parameters analyzed included calorific value, fuel density, effective shaft power, fuel consumption, thermal efficiency, exhaust gas temperature, and carbon monoxide emissions. The results showed that increasing the camphor concentration reduced the fuel calorific value from 12,347 kcal/kg to 6,306 kcal/kg and increased the density from 750 kg/m³ to 780 kg/m³. The addition of camphor tended to increase effective shaft power and reduce measured fuel consumption. However, carbon monoxide emissions increased significantly, particularly at camphor concentrations of 20–30% and at low engine speeds. At 1,200 rpm, CO emissions increased from 0.7% for pure gasoline to 8.7% for the 30% camphor mixture. Therefore, camphor addition creates a trade-off between improved engine performance and deteriorating exhaust emission quality. High camphor concentrations are not recommended, while concentrations of 5–10% require further testing to assess their technical effectiveness, environmental impact, and long-term effects on engine components.
