Indonesia faces various nutritional problems, one of which is central obesity. This condition occurs due to excessive energy intake that surpasses the amount of energy used for metabolism and daily activities. The excess energy is stored as fat tissue, which eventually leads to weight gain and increases the risk of various metabolic diseases. This study aims to examine the risk factors for central obesity in the community at Mon Geudong Public Health Center, Lhokseumawe City.This study employs a descriptive observational method with a cross-sectional survey design. The population consists of 1,121 individuals, and the sample was obtained using a non-probability sampling technique with accidental sampling, resulting in a total of 100 respondents. Data collection was conducted through questionnaires and waist circumference measurements using a measuring tape. Data were analyzed using univariate analysis to examine the distribution of respondent characteristics.The results indicate that the most affected age group is 56–65 years (49.0%). Based on gender, more women (80.0%) experience central obesity compared to men (20.0%). The majority of respondents are unemployed, possess good knowledge levels, and 69.0% have a family history of central obesity.The study concludes that the primary risk factors for central obesity include age, gender, occupation, and family history. However, knowledge level is not considered a risk factor for central obesity. This research is expected to serve as a basis for central obesity prevention efforts through education and the promotion of a healthy lifestyle in the community.

Tuna fisheries are a strategic sector in Indonesia's fishing industry, contributing significantly to the national economy. Albacore tuna (Thunnus alalunga) has high economic value and is one of the main commodities in international trade. This study aims to analyze the effect of different longline setting times on albacore tuna catches in the Seas of Benoa Harbor. The setting times compared were morning (08:00–10:00) and afternoon (14:00–16:00), focusing on the quantity and weight of the catch. The research method used was an experimental approach with two setting time treatments and nine replications for each treatment. Data obtained were analyzed using a T-test to determine significant differences between morning and afternoon catches. The results showed that the average catch in the morning was higher than in the afternoon, both in terms of individual count and fish weight. The average fish weight obtained in the morning was 63.78 kg, while in the afternoon, it was only 28.67 kg. Statistical analysis indicated a significant difference between morning and afternoon catches, with a T-Statistic value of 2.38, which exceeded the T-Critical value (2.12) at a 5% significance level (p-value = 0.0366). This suggests that the morning setting time is more optimal for catching albacore tuna than the afternoon setting. Catch variation was also greater in the morning, as indicated by a higher standard deviation compared to the afternoon. This difference may be attributed to the daily migration patterns of albacore tuna, which are more active in feeding during the morning, as well as environmental factors such as water temperature and light intensity. Based on these findings, this study recommends that fishers in the Seas of Benoa Harbor should set their longline fishing gear in the morning to maximize their catch.

Supplier selection is a strategic element in supply chain management to ensure operational efficiency and business sustainability. This study aims to determine the best urea supplier for PT DSSA 1, a textile company specializing in dyeing and finishing processes, using the Analytic Network Process (ANP) method. This method was chosen for its ability to systematically analyze interdependencies among criteria, leading to more accurate and comprehensive decision-making. Data were collected through direct observation, in-depth interviews with internal company sources, and relevant literature reviews. The analysis was based on five main criteria: quality, price, service, delivery, and flexibility, each further broken down into sub-criteria. The results indicate that quality is the most critical criterion, with the highest weight of 23.19%, followed by price, service, and delivery, each with relatively balanced weights of 19.93%. Flexibility, although ranked last with a weight of 17.01%, remains relevant, especially for urgent orders. Based on the analysis, Supplier A was identified as the best choice with the highest overall weight, followed by Supplier B and Supplier C. This study provides practical contributions by offering strategic recommendations for PT DSSA 1 in selecting suppliers that support production efficiency and business sustainability. The study is limited in the scope of criteria and the number of suppliers analyzed. Future research is recommended to explore more variables, expand the sample size, and consider the implementation of digital technologies to optimize the supply chain.

Health risk stratification is crucial for preventive healthcare, yet existing models often rely on binary classification generalized disease prediction, neglecting personalized health indicators and graded risk levels. Many studies apply feature selection techniques like Relief and Univariate Selection without quantifying the weighted impact of features. To address these gaps, this study introduces a Big Data-driven Health Index (HI) framework using PySpark for scalable health risk stratification. The HI is computed as a weighted sum of health-related features using SHAP Analysis, XGBoost, Random Forest, and Correlation Analysis. PySpark enables efficient processing of large-scale health data, and individuals are classified into Low and High Risk. Optimal classification thresholds are determined using the Youden Index from the ROC curve to balance sensitivity and specificity. Personalized health recommendations are generated based on risk categories to guide preventive interventions. Performance evaluation reveals that Correlation Analysis achieves 100% precision and 98.90% recall, outperforming other methods. SHAP prioritizes recall but has low precision, while XGBoost and Random Forest improve precision but struggle with recall. By leveraging Big Data techniques with PySpark, this study enhances computational efficiency, scalability, and classification accuracy, addressing prior research limitations and providing a robust data-driven approach to personalized health monitoring.

EGCG has a hypocholesterolemic effect and suppresses cholesterol absorption in the intestine, L-theanine itself has physiological effects such as relaxation activities, and caffeine is useful in reducing food intake and has a thermogenic effect which can encourage weight loss.

The use of probiotics is very important in cultivation activities. Probiotics are live microorganisms that have a beneficial effect on the host by balancing the microflora in their intestines. In increasing the nutritional content of artificial feed (pellets), the bacteria in probiotics have a mechanism for forming several enzymes for digesting feed. This study aims to determine the effect of giving delacto probiotics at different doses in artificial feed on the absolute weight growth of tilapia (Oreochromis niloticus). Probiotics are mixed with feed using a biofloc cultivation system. The method used in this research was an experimental method with a Completely Randomized Design (CRD) with 4 treatments and 6 replications, namely by adding different doses to the treatments. Treatments A (8ml/kg), B (16 ml/kg), C (24 ml/kg) and D (32 ml/kg). The parameter observed was absolute weight growth. Water quality supporting parameters include temperature, pH and DO. Data were analyzed using the ANOVA test. Based on the research results, it shows that giving different doses of delacto probiotics has a significant effect on the absolute weight growth of tilapia (Oreochromis niloticus). Treatment A (8 ml/kg) gave the lowest absolute weight growth of 32.83 grams and treatment D (32 ml/kg) gave the highest absolute weight growth of 40.57 grams. Water quality parameters include water temperature ranging from 25.3 – 26.1֯C, acidity ranging from 7.5 – 8.0. And dissolved oxygen ranges from 4.7 – 5.3 ppm. The results of analysis of variance (ANOVA) for the three water quality parameters showed no differences between treatments (Oreochromis niloticus) fry.

Giving probiotics such as probiotic boster on feed greatly helps the growth of absolute weight in Catfish seeds because the good bacteria contained in these probiotics help facilitate catfish seeds in digesting the feed so as to increase the efficiency of the feed. This study aims to see how effective the probiotic administration is. The study was conducted in Kramas District, Gianyar regency, Bali Province for 30 days using experimental methods, using a complete randomized design with a total of 4 treatments and 6 repetitions. Treatment A is by giving 3 ml of probiotic boster every 1 kg of feed. Treatment B by giving 5 ml probiotic boster every 1 kg of feed. Treatment C by giving 7 ml probiotic boster every 1 kg of feed. Treatment D by giving 9 ml probiotic boster every 1 kg of feed. In this study showed significantly different results on the addition of probiotic boster with different doses on the growth of absolute weight of catfish fry aged 1 month-2 months. Treatment D gave the highest result with an absolute weight gain of 55.33 grams, and treatment a showed the lowest result with an absolute weight gain of 25.17 grams. Water quality Data during the study obtained water temperature ranges from 27-29 oC, acidity ranges from 7-8, and dissolved oxygen ranges from 3.34 to 4.26 ppm. The results of the analysis of variance (ANOVA) of the three parameters of water quality there is no difference between the treatment and the life range of catfish fry (Clarias sp.)

According to the anthropometric standards for evaluating children's nutritional status, stunting is a growth failure condition based on the weight-for-age (W/A) or height-for-age (H/A) index, where the measurement results fall within the threshold (Z-Score) of -2 SD to -3 SD (short/stunted) and -3 SD (very short/severely stunted). In 2023, 27.3% of the toddlers in Penfui Timur Village were still stunted. The purpose of this study is to ascertain how stunting reduction policies are being implemented in Penfui Timur Village, Kupang Regency. This research used a qualitative descriptive method with data collection techniques of in-depth interviews, observation and documentation. The informants in this study is 8 informants, consisting of 2 main informants and 6 supporting informants. The main informants are the head of the Penfui Timur village and the nutrition staff of the Tarus Health Center. The supporting informants are 2 posyandu cadres, mothers of stunted toddlers, pregnant women, village residents, and teenage girls.The data analysis process in this research begins by collecting data from interviews and then reducing the resulting data. After that, the data is presented and concluded. The study's result showed that although the policy has been applied effectively, it still falls short of the implementation theory's requirements. The implementers' low educational and human resource levels, the ignorance of expectant mothers and parents of children with stunted growth, and the lack of facilities and infrastructure are the contributing reasons. Although the village government's communication component with other implementing parties has been functioning smoothly, communication with the leaders of the target community has not been at its best. The policy implementers are already familiar with the methods and duties associated with their respective areas of responsibility. The bureaucratic structure's policy implementers are already familiar with the technical facets of reducing stunting. Based on the results of the study, it is recommended to increasing the knowledge involved in  implementation policy for stunting reduction

Vannamei shrimp is one of the shrimp species with economic value and is one of the national leading commodities. On the other hand, one of the problems in vannamei shrimp cultivation is its slow growth, slow growth is caused by the less optimal absorption of nutrients in the feed. In dealing with these problems, one of the things that is done is the administration of probiotics. The addition of probiotics such as Biolacto containing Lactobacillus sp bacteria to the feed can increase the appetite of shrimp. This study aims to determine the effect of biolacto probiotics on feed on the growth of the absolute weight of vannamei shrimp. This study used a Complete Random Design (RAL) with four treatments: A (feed without a mixture of probiotics), B (probiotics 2 gr/100 gr feed), C (probiotics 4 gr/100 gr feed), and D (probiotics 6 gr/100 gr feed). Treatment B with a concentration of probiotics 2gr/100g feed gave the highest absolute weight growth of 9.2 gr. Water quality data during the study were obtained with water temperature ranging from 28.5 – 29.2°Celsius, salinity ranging from 36 – 37 ppt, pH ranging from 7.5 – 8.0, and dissolved oxygen ranging from 4.0 to 4.63 mg/l. The results of the ANOVA analysis of the four water quality parameters showed no difference between treatments and were in the optimal range of life of vannamei shrimp (Litopenaeus vannamei).

In the last ten years, Indonesia has been carrying out massive infrastructure development. The goal is to facilitate community mobility which has an impact on economic growth. Infrastructure development also aims to increase the Human Development Index even though it does not directly affect it. One of the provinces that contributed to infrastructure development was East Java, with the Human Development Index during the 2018-2022 period increasing and tending to stagnate. For this reason, the purpose of this study is to identify the influence of infrastructure development on the Human Development Index, including identifying the influence of poverty on the Human Development Index. The research methodology used is quantitative with  a Geographically Weighted Panel Regression (GWPR) approach that allows to comprehensively identify the Regional Development Index in East Java. The results obtained were that the variables of Infrastructure Development with the dimensions of Road Length (6,172) and Number of Schools (2,686) had an impact on the Human Development Index in East Java. Meanwhile, the poverty variable (-6,139) has no effect on the Human Development Index (HDI). However, simultaneously the variables of Infrastructure Development and Poverty affect the National Development Index (HDI) with a calculation of 64.42 > 2.4202.

The addition of probiotics such as Lactobacillus sp to fermented feed is expected to improve nutrient digestibility, suppress the growth of pathogenic microorganisms, and improve feed conversion efficiency, thereby promoting optimal shrimp growth. This study used an experimental method on vannamei shrimp doc 80 using a complete randomized design (RAL) with four treatments: P0 (feed without fermentation as a control), P1 (feed fermentation for 0 hours 10ml/100g with Lactobacillus sp), P2 (feed fermentation for 24 hours with 10ml/100g Lactobacillus sp), P3 (feed fermentation for 48 hours 10ml/100g Lactobacillus sp), P3 (feed fermentation for 72 hours 10ml/100g Lactobacillus sp) by doing 6 repetitions which were carried out for 1 month/30 days in the maintenance tub. The results showed that Treatment A without fermentation gave absolute growth with an average of 1 gr, Treatment B with no fermentation gave absolute growth with an average of 1.89 grams, Treatment C with a fermentation time of 48 hours gave absolute weight growth with an average of 2.15 grams, Treatment D with no fermentation gave absolute growth with an average of 0.74 grams. Meanwhile, the water quality parameters during the study were obtained with water temperature ranging from 28.3-29.6o C, pH ranging from 7.8-8.0, and dissolved oxygen ranging from 4.03-4.66 mg/l. With the anova test, the absolute weight growth showed that with different fermentation time differences, there was a real effect on the growth of vannamei shrimp in C treatment, which was 2.15 gr. And in the results of the anova test, the four water quality parameters were not different between the treatments and were in the optimal range in the life of vannamei shrimp. Based on this study, it can be suggested that the optimal fermented feed is in the time range of 48 hours and there is further research for doc 80 and above.

The objective of this study was to determine the effect of different percentages of natural feed (Tubifex sp.) and artificial feed on the absolute weight gain of striped catfish (Pangasius hypophthalmus) fry. The study was conducted at PBIAT Muntilan for 30 days using an experimental method. A Completely Randomized Design (CRD) was applied with five treatments and five replicates. The treatments were as follows: A (100% pellet), B (75% pellet + 25% Tubifex sp.), C (50% pellet + 50% Tubifex sp.), D (25% pellet + 75% Tubifex sp.), and E (100% Tubifex sp.). ANOVA analysis showed that different proportions of natural feed (Tubifex sp.) and artificial feed significantly affected absolute weight gain. The most optimal feeding ratio for enhancing the absolute weight gain of striped catfish fry was found in treatment E, where 100% Tubifex sp. was provided, resulting in the highest absolute weight gain of 4.876 grams. Water Quality Parameters: During the study, the recorded water temperature ranged from 25.1 to 25.4ºC, pH ranged from 6.7 to 6.8, and dissolved oxygen ranged from 6.6 to 6.7 ppm. ANOVA analysis of these three water quality parameters showed no significant differences among treatments. However, the temperature was below the optimal range for the growth of striped catfish (Pangasius hypophthalmus) fry.

Pearl catfish (Clarias gariepinus) has advantages when cultivated, namely fast growth, efficient feed, has a uniform size and is resistant to disease (Matasina and Sartika, 2020). The success of a fish farming business can be determined by its feeding management, because feed that is consumed effectively by fish can make fish experience good growth (Hanief, et.al, 2014).The purpose of this study was to determine the effect of natural feeding of Daphnia magna and silk worms on the absolute weight growth of pearl catfish (Clarias gariepinus) seeds aged 5 days. The method used is an experimental method that aims to determine the effect of feeding Daphnia sp and silk worms on the absolute weight growth of pearl catfish seeds (Clarias gariepinus) aged 5 days in a controlled environment. This study was arranged in a completely randomized design (CRD) with 3 (three) treatments and each consisting of 9 (nine) repetitions, thus there were 27 experimental units. Treatment A 100% silk worm (control), treatment B: 100% Daphnia sp and treatment C 50% Daphnia sp and 50% silk worm. The parameter observed was absolute weight growth. The results showed that the highest absolute weight growth was obtained from treatment A at 1.22 g, then treatment C at 0.76 g and the lowest was treatment B at 0.33 g. Based on the LSD further test, all feed treatments had significant differences on the absolute weight of fish fry. Based on the LSD further test as a whole shows that all feed treatments have significant differences on the absolute weight of fish seeds.

Toddler weight monitoring is a routine activity carried out by the integrated health post (posyandu). Routinely weighing toddlers means that toddler growth can be monitored intensively. The sooner it is found, the sooner cases of malnutrition or severe malnutrition will be handled. Data from the Ministry of Health shows that 65% of active integrated health posts in Indonesia have not reached the national target of 80%. The purpose of this activity is to optimize integrated health post activities. This community service activity has an influence on increasing mothers' knowledge of the importance of monthly weighing of toddlers.

The phenomenon that occurs in the load lifting system is the need for an efficient and reliable mechanism to move the crane hoist pulley vertically and horizontally.
