Distribution is the process of moving, managing, and storing goods from suppliers to customers in the supply chain. This process includes not only the delivery of raw materials from suppliers to manufacturers, but also the distribution of finished products to the end consumer. Distribution plays an important role in a company's profitability because it affects operational costs, delivery efficiency, and perceived value by customers. Successful well-managed distribution will increase customer satisfaction and strengthen the company's competitiveness in the market. PT. XYZ is one of the LPG distributors that provides 3 kg cylinders. This company serves a variety of consumers, ranging from households, small businesses, to retailers, with a coverage of distribution areas in Serang City. The distribution process is carried out based on sales orders and needs in 14 bases, where each base has a different level of demand according to consumer needs. However, PT. XYZ faces obstacles in achieving the optimal level of service, where the average service level only reaches 97.40%. An imbalance between inventory and demand at the base often leads to an oversupply or understock, resulting in backorders on some demands. This condition has a negative impact on customer satisfaction and overall distribution effectiveness. To overcome this problem, PT. XYZ developed a distribution dashboard by applying the Distribution Requirements Planning (DRP) method. Through this approach, distribution planning becomes more systematic, base needs can be met appropriately, and stocks can be managed more effectively. This dashboard also supports delivery scheduling and more coordinated marketing activities. The results of the implementation of the DRP dashboard in 2023 show a significant increase with a service level that has successfully reached 99%, minimizing backorders, and increasing customer trust and satisfaction.

This study aims to identify and compare the prevalence of eating disorders and body image disturbances among female athletes and non-athlete members of fitness clubs. Given the rising societal emphasis on physical appearance and performance, young women are increasingly exposed to unrealistic body ideals, potentially increasing the risk of psychological issues such as body dissatisfaction and disordered eating behaviors. The research employed a descriptive quantitative design involving 100 women aged 18–25 years, consisting of 50 athletes actively participating in competitive sports and 50 non-athletes who regularly attend fitness clubs for general health purposes. Data were collected using two standardized instruments: the Body Image Concern Inventory (BICI) to assess levels of body image disturbance, and the SCOFF questionnaire to screen for symptoms of eating disorders. Results indicated that 34% of female athletes reported high levels of body image disturbance, compared to only 2% of non-athletes. Additionally, symptoms of eating disorders were present in 54% of athletes, while 14% of non-athletes showed similar tendencies. Statistical analyses using Mann-Whitney U and independent samples t-tests confirmed a significant difference between the two groups (p < 0.05), suggesting that athletes may be at a higher risk for developing these psychological issues. These findings underscore the psychological pressures faced by female athletes, who are often required to maintain specific body standards to meet performance expectations. The study highlights the urgent need for preventive measures, including psychological support services and educational interventions that promote healthy body image and eating habits. Implementing such programs in both sports and general fitness environments can help reduce the prevalence of these disorders and foster a healthier relationship with body image among young women.
