Abstract

XYZ Milk Tofu Home Industry is a Home Industry that is quite developed and is able to meet market demand in several regions, it's just that in this case the form of the need for the preparation of raw materials is still fairly manual or traditional using only instinct or estimates, so you have to order raw materials over and over again which results in an increase in ordering costs. The purpose of this study is to increase the maximum ordering capacity. The method used is EOQ (Economic Order Quantity) by taking into account ordering costs and storage costs. The application of the EOQ method is expected to be able to handle the problems that have occurred so far. Based on the results of cost analysis, orders increased from 90.20 Kilograms to 408,29 Kilograms. With the EOQ (Economic Order Quantity) method, it can also be seen that the value of the Safety Stock is 267 Kilograms and the Pre-Order Point is 19 Kilograms, to prevent delays in the supply of raw materials. The conclusion of this research is that by applying the EOQ method, it is proven that production costs in the production of milk tofu can be reduced to get a more optimal profit.

Abstract

SARS-COV-2 a virus which caused the global pandemic Coronavirus-2019 (COVID-19) has infected about 659,108,952 among, with 6,684,756 deaths in the world as stated by WHO on December 23 2022. Basil leaves have antiviral potential, especially in groups flavonoids. People who are exposed to the COVID-19 virus are given many drugs that cause many side effects. Therefore, it is advisable to consume drugs from natural ingredients that are low in side effects such as basil leaves. This study aims to predict flavonoid derivative compounds from basil leaves that have the potential as an anti-viral drug for COVID- 19 by in silico, which has high affinity with low side effects. The method used is molecular docking for target analysis, prediction of ADME, and prediction of toxicity. The results of this study, there is a naringenin compound that has the highest potential to become an antiviral for COVID-19 with a ∆Gibbs value of -4.04 kcal/mol and an KI of 1.09 mM. These flavonoid derived compounds comply with Lipinski rules, so that the flavonoid content in basil leaves can help treat COVID-19 as a drug derived from natural ingredients that has antiviral potential with low side effects.

Abstract

Background: Nutritional problems among children and adolescents remain a major public health issue in Indonesia, with challenges including both undernutrition and overnutrition. One contributing factor is the increasing consumption of ultra-processed foods (UPF), especially among adolescents. UPFs are industrially processed foods that are high in energy, fat, sugar, and salt, but low in essential nutrients. Objective: To evaluate the relationship between UPF consumption and nutritional status among adolescents. Methodology: This study used an observational design based on data from a systematic review. Results and Discussion: A review of various national and international studies shows that most research found a positive association between high UPF consumption and excessive nutritional status, such as overweight and obesity. However, some studies did not show a significant relationship, which may be influenced by other factors such as physical activity, sedentary behavior, and socioeconomic conditions. Furthermore, the type of UPF consumed also affects its impact on nutritional status, with energy-dense foods showing a stronger correlation than beverages. Conclusion: High consumption of ultra-processed foods has the potential to be an independent risk factor for excessive nutritional status in adolescents, although individual characteristics and lifestyle variability should be considered as moderating factors in this relationship.

Abstract

This study aimed to determine: (1) the difference in the effects between static and dynamic core training programs on soccer skills, (2) the difference in soccer skills between athletes with high and low motor performance, and (3) the interaction between training programs and motor performance on soccer skills. This study employed an experimental method with a 2 × 2 factorial design. The population consisted of 27 male players from SSB Watuska Surakarta, with a sample of 24 players selected using purposive sampling and grouped based on the extreme groups design principle. The research instruments included motor performance tests and soccer skill tests, which were standardized using T-scores. Data analysis was conducted using a two-way ANOVA test with a significance level of α = 0.05, followed by pairwise comparison tests. The results showed that: (1) there was no significant difference in the effect between static and dynamic core training programs on soccer skills (p = 0.627 > 0.05), with a small effect size (η² = 0.012); (2) there was a significant difference between players with high and low motor performance (p = 0.023 < 0.05), with a large effect size (η² = 0.234), where the low motor performance group demonstrated substantially greater improvement in soccer skills compared to the high motor performance group; and (3) there was no significant interaction between training program and motor performance level on soccer skills (p = 0.706 > 0.05). The conclusion of this study indicates that the effectiveness of core training is more influenced by the individual’s initial motor performance capacity rather than the type of training method. Core training is highly effective for players with stability deficits (low motor performance), but it must be applied carefully in players with high motor performance to avoid overload, which may lead to increased muscle stiffness and reduced movement elasticity.
