Analisis Kandungan Zat Besi, Protein dan Mutu Organoleptik Cookies Substitusi Tepung Ikan Manyung dan Tepung Bayam Hijau sebagai Selingan Remaja Anemia

2024-11-05T17:56:40+00:00

Anemia is a global health problem whose prevalence is still quite high. Iron deficiency anemia occurs due to a lack of iron in the blood or low levels of hemoglobin (Hb) in the body. The anemia threshold for adolescent girls is 12 g/dl, while for adolescent boys it is 13 g/dl. One way to increase iron intake in teenagers is to develop cookies that use substitutes for catfish flour and green spinach flour, which can be a healthy alternative snack. This research aims to analyze the effect of substitution of catfish flour and green spinach flour on the nutritional content of cookies. The research design used was a True Experimental Design with a Completely Randomized Design (CRD), which involved 4 treatments and 6 replications. The treatments applied included the ratio of wheat flour: catfish meal: green spinach flour at P0 (100:0:0), P1 (65:15:20), P2 (50:20:30), and P3 (30:25:45). The research results showed that the addition of green spinach flour could increase the macronutrient and iron content in cookies, with the highest iron levels found in the P3 treatment.

One common health issue among adolescents, particularly teenage girls, is anemia. Anemia is a condition where the number of red blood cells or hemoglobin (Hb) is below normal, often due to a diet low in iron. Green beans, which are rich in iron, can be used as an alternative ingredient in brownies for individuals with anemia. Cooking techniques play a crucial role in preserving the nutritional content of food. In brownie preparation, the techniques used are steaming (with hot steam) and baking (with dry heat in an oven). This study employs a True Experimental Design with a Completely Randomized Design (CRD), involving 3 treatment levels, 1 control, and 6 replications. Treatments include comparisons of wheat flour to green bean flour ratios: P0 (100%:0%), P1 (75%:25%), P2 (50%:50%), P3 (25%:75%). Statistical analysis uses Kruskal-Wallis and Wilcoxon tests. The results indicate significant differences in protein, moisture, and iron content between steaming and baking techniques, but no significant differences in fat, carbohydrates, and ash content. This suggests that cooking methods affect the nutritional content and acceptability of brownies, with steamed and baked brownies showing variations in nutrient content and acceptability, particularly in protein, moisture, and iron.

2024-12-14T02:31:23+00:00

The environment is a unity of space that includes all natural elements, including living things and the interactions between these elements. In recent decades, waste pollution, especially microplastics, has become a major threat to aquatic ecosystems and human health. Microplastics are small plastic particles that are dispersed in various aquatic ecosystems and can accumulate in the food chain. This study aims to assess the abundance of microplastics in West Sumatra waters, especially in coastal areas, rivers and lakes. The method used in this research is literature review. Based on the literature review, microplastics were found in sediments and marine organisms, such as fish contaminated by microplastics, with the dominant type being fibers. Some areas, such as Carocok Beach, Bungus Bay and Purus Beach, show high abundance of microplastics, which is associated with human activities and poor waste management. These findings emphasize the importance of better waste management to reduce microplastic pollution. This study also provides a clearer picture of the distribution of microplastics, their impacts on aquatic ecosystems and human health, and suggests more effective plastic waste management policies in West Sumatra to maintain the sustainability of aquatic ecosystems and public health.

2024-12-21T12:05:09+00:00

Potato production in Sumatra plays an important role in supporting the national agribusiness sector. However, the uncertainty of factors such as weather, soil quality and farming practices often leads to fluctuations in production yields. This research aims to improve the accuracy of potato production prediction by applying the Backpropagation method in Artificial Neural Network. This research aims to find the best architecture model using the backpropagation method in predicting potato production in Sumatra. The data used was obtained from the Central Bureau of Statistics (BPS) and divided into training and testing data. This study tested several artificial neural network (ANN) architectures with models 6-10-1, 6-30-1, 6-50-1, 6-70-1, and 6-100-1. The results showed that the 6-50-1 architecture model gave the best results with 83% accuracy and 1617 epochs. In addition, this model has a low Mean Squared Error (MSE) on both training and testing data, which indicates good performance in potato production prediction. By using the backpropagation algorithm, this study provides an effective solution to improve the prediction of agricultural commodity production, particularly potatoes, which is important for decision-making and distribution planning. These findings can assist farmers and policy makers in planning more efficient production strategies and anticipating production challenges. This research confirms the importance of applying artificial intelligence technology to support the sustainability of the agricultural sector in Sumatra.
