The lack of a systematic calculation approach makes it difficult for APR Nine to monitor fabric raw material inventory, resulting in raw material purchases still being based on habit and intuition. With a total inventory of 2,001 rolls and raw material usage of 1,803 rolls of fabric, there were seven times of excess stock and five times of shortage during the period of October 2024 to September 2025. The difference between the two was 198 rolls. This study uses the Economic Order Quantity (EOQ) method to analyze fabric raw material inventory control. This study uses a quantitative approach with descriptive analysis using data from the period of October 2024 to September 2025. The results of the study indicate that 1694 orders with an ordering frequency of 10 times, a safety stock of 29 rolls, and a reorder point of 35 rolls are the ideal quantities when using the Economic Order Quantity (EOQ) approach. Compared to the previous APR Nine approach, the application of the Economic Order Quantity (EOQ) method is more effective in reducing overall inventory costs from Rp. 5,011,949.35 to Rp. 4,508,824.67.

Micro, Small, and Medium Enterprises (MSMEs) play a strategic role in supporting Indonesia’s economic development, not only by contributing to economic growth but also by creating employment opportunities. Along with the rapid increase in the number of MSMEs, competition among business actors has become increasingly intense, including in the knitted industry, which requires consistent product quality and efficient production processes. In this context, this community service program is designed to strengthen the competitiveness of MSMEs by improving their understanding and implementation of machine maintenance. Proper and well-planned maintenance practices are expected to reduce the risk of machine failure and minimize product defects. The activities were carried out through a series of socialization sessions, training programs, and technical assistance focused on machine maintenance calculations. The expected output of this program is a community service report that will be further developed into a scientific article and published in the Indonesian Journal of Community Service.

In Indonesia, micro, small, and medium enterprises (MSMEs) have long been recognized as a very important business sector due to their various real roles in the economy. However, MSMEs often face many obstacles in running their businesses. More incentive support from various parties, especially the government, is needed for the development of MSMEs. In order to overcome the problems faced by MSMEs and support their sustainability, a KKU (Business Field Study) activity was carried out by Group 15 at the KKU-11 of the Institute of Technology and Business (ITB) Adias Pemalang at the MSME “Ev_Kids Product.”After conducting an observation phase, several problems faced by the SME were identified, including the lack of social media for marketing, failure to calculate the Cost of Goods Sold (COGS) and maintain simple accounting records, absence of a business logo, banners, promotional image designs, organizational structure, business profile, product catalog, stamps, receipt books, and product attributes. Additionally, the SME had never produced a production video or promotional video.After conducting the observation phase, KKU actors formulated several business development assistance programs, namely creating social media accounts, calculating the Cost of Goods Sold (COGS), creating simple bookkeeping, creating a business logo, banners, promotional image designs, organizational structure, business profile, product catalog, stamps, note books, and product attributes in the form of hangtags. They also created production videos and promotional videos.

This research aims to analyze the risk factors of occupational accidents and identify effective prevention efforts within the context of Micro, Small, and Medium Enterprises (MSMEs), specifically at Inkside Sablon. This qualitative study, employing a case study approach, utilized in-depth interviews, participant observation, and documentary analysis for data collection. The findings indicate that occupational accident risk factors at Inkside Sablon are influenced by several aspects, including human factors such as lack of safety awareness and fatigue, environmental factors like inadequate ventilation and suboptimal lighting, and equipment factors such as non-ergonomic tools and insufficient maintenance. The prevention efforts implemented by Inkside Sablon are still partial and not well-structured, thus requiring the integration of more comprehensive safety programs, such as enhanced safety and health (OSH) training, provision of appropriate personal protective equipment (PPE), and improvements in management and supervision systems. It is expected that the implementation of these measures will increase worker awareness and reduce the number of occupational accidents, thereby creating a safer and more productive work environment

This study aims to analyze the thermal performance of the heating system in a small-scale plastic bolt molding machine using LDPE material, in order to determine process parameters that are efficient while maintaining product quality. The method used includes experimental testing at two set-point temperatures (90 °C and 120 °C), measurement of melting time and feed mass per cycle, as well as heat balance calculations separating the contributions of conduction, convection, and radiation on the barrel heated by a band heater. In addition, the power/energy requirement per cycle and productivity projections based on hopper capacity were calculated. The results show that increasing the set-point from 90 °C to 120 °C accelerates melting from ±240 s to ±180 s (≈25% faster). Heat transfer analysis confirmed the dominance of conduction (≈329.7 W at 90 °C and ≈471 W at 120 °C), while convection and radiation contributions were much smaller; the total system heat rate was ≈342.7 W (90 °C) and ≈490.8 W (120 °C). The discussion highlights the process trade-off: higher set-points increase production rate and mold filling quality (due to lower melt viscosity), but may raise energy consumption per cycle and require tighter mold temperature control to limit shrinkage/warpage. The practical implications for SMEs are the need for efficiency strategies based on barrel insulation, heater contact area optimization, and correlation of temperature-time settings with quality and energy consumption targets. This study concludes that controlled temperature and heating duration, supported by simple yet targeted thermal design, can improve cycle time consistency, dimensional precision, and energy efficiency in small-scale plastic bolt molding machines.
