PT Pos Logistik Indonesia (POSLOG) is a company that provides integrated logistics services across various sectors. One of the main commodities delivered regularly each year is rice from Bulog, which has a significant distribution volume. At present, PT Pos Logistik Indonesia – Branch Bandung still relies on third-party (vendor) transportation services, which leads to suboptimal company revenue and creates dependency on external parties. This study aims to conduct a comparative analysis of operational cost efficiency between the use of company-owned vehicles and rented vehicles. The analytical methods applied include Vehicle Operating Costs (VOC), Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period (PP). The analysis results show that the cost of using vendor services amounts to IDR 710 per kilogram, while the cost of using company-owned vehicles is only IDR 284 per kilogram. Furthermore, the NPV value reached IDR 2,732,364,981, the IRR was 129.94%, and the Payback Period was 1 year and 9 months. Based on these findings, investing in company-owned vehicles is proven to be more efficient, economical, and feasible to improve profitability and ensure business sustainability.

Dawet Ayu in Banjarnegara Regency is one of the traditional culinary micro, small, and medium enterprises (MSMEs) that until now is still able to survive and continue to grow. This typical beverage product not only has cultural value, but also has the potential to be a promising economic source for the local community. However, the reality on the ground shows that Dawet Jabung's business actors are still facing various serious obstacles. Limited understanding of business management, difficulties in calculating production costs in detail, and inability to determine the right selling price of products are the main obstacles. In addition, the low knowledge related to aspects of marketing, promotion, and business communication strategies makes it difficult for this business to expand the market. As a result, some business actors have actually experienced a significant decrease in sales from year to year. To answer these challenges, community service activities are carried out through two approaches, namely Action and Quality Awareness and Rapid Rural Appraisal (RRA). Action and Quality Awareness are carried out through extensive counseling, lectures, and mentoring aimed at increasing the knowledge of business managers. In this activity, business actors are guided to understand the importance of financial recording, cost management, and strategies to improve product quality. Meanwhile, the RRA method is used to identify real needs in the field, as well as prepare training, mentoring, and coaching programs that are relevant to business conditions. The results of the activity showed an increase in the ability of partners to classify production costs into the categories of raw materials, labor, overhead, marketing, and transportation. In addition, business actors are now more skilled in determining selling prices based on the realization of costs incurred, not just estimates. They also began to compile simple bookkeeping related to assets, debts, and capital, so that business management became more professional, transparent, and sustainable

This qualitative research investigates the critical factors inhibiting ship arrival efficiency and their impact on shipping agency performance at PT. Berkah Tata Baruna Banten Branch. Through comprehensive interviews with maritime professionals, port operators, and agency management, the study examines three primary variables: pilot tugboat services, cargo loading-unloading productivity, and document processing efficiency.

Respondents emphasized that transparent communication channels, standardized documentation procedures, and adequate training programs are essential to building resilient port systems. Moreover, the research shows that investment in digital platforms for real-time data sharing could accelerate clearance processes, while workforce development initiatives would ensure higher service reliability. The study contributes theoretically by developing frameworks of integrated maritime service performance and practically by offering policy-oriented recommendations to strengthen agency competitiveness. Overall, the findings provide valuable insights for stakeholders seeking to enhance Indonesia’s maritime logistics capacity, aligning operational improvements with the nation’s broader economic and global shipping ambitions.

This study aims to describe the role of parents in supporting the achievements of sepak takraw athletes in Batang Regency. Athlete achievement is determined not only by individual abilities and training received, but also by support from their immediate environment, particularly family. In this context, parents play a strategic role in the coaching and development of young athletes, both physically, mentally, and emotionally. This study used a qualitative approach with data collection techniques such as in-depth interviews, direct observation, and documentation. The subjects in this study consisted of parents of sepak takraw athletes, athletes who have achieved success at the regional level, and coaches involved in coaching. Through this approach, comprehensive data was obtained regarding the forms of support provided by parents. The results show that parents play a crucial role in encouraging athlete success. This role is manifested through various forms of support, including moral support in the form of motivation and encouragement, material support such as providing training equipment and transportation costs, and direct involvement in monitoring children's development. Parents also actively communicate and collaborate with coaches and clubs to create a conducive coaching environment. In addition, parents' positive attitudes in appreciating their children's interests and talents contribute to the athletes' high level of self-confidence and commitment. Thus, active parental involvement has been shown to significantly contribute to improving the performance of sepak takraw athletes, particularly at the district level. This research suggests the need for systematic parental involvement in regional sports development programs.
