Abstract

In Indonesia, including at the Faculty of Engineering, the higher education curriculum integrates Real Work Lecture Activities (KKN). KKN aims to improve students' ability to solve community problems using science and technology. This article discusses the implementation of KKN at the Faculty of Engineering (2025),, with special emphasis on the role of students in environmental management, community welfare, and local infrastructure development. Through involvement in construction, design, and infrastructure maintenance projects, students learn to collaborate with communities, improve their technical abilities, and understand how engineering projects have a social impact. Students' social awareness and responsibility as prospective engineers are also increased through the application of problem-based learning and community service. The results of KKN at the Faculty of Engineering really help academic development and sustainable development and quality of life.

One of the companies in East Bekasi is a company engaged in the bread industry, with the product being sandwiches. The purpose of this research is to perform raw material efficiency and cost savings of raw material inventory. In this study, identified the bread production process for 1 period (3 months). It is known that this company ordered raw materials, namely 2100 kg of flour and 480 kg of granulated sugar. However, in reality, only 1537 kg of wheat flour was used and 379 kg of granulated sugar.

Abstract

Family Farma Pharmacy is a pharmacy that provides pharmaceutical services in Bekasi Regency. There are 50 types of medicines provided in this pharmacy, but there is no medicine grouping yet. Medicine inventory control is still done manually or by monitoring medicine stocks one by one. So there is no precise and effective calculation to determine total reorders. Therefore, the aim of this research is to grouping medicines, control medicine supplies and reorder it. The methods used are Always Better Control (ABC), Economic Order Quantity (EOQ), and Reorder Point (ROP). The findings obtained were by grouping 50 types of medicines to obtain 10 types of medicines belonging to group A, 10 types of medicines in Group B, and 30 types of medicines in Group C based on the results of the ABC method. Then the EOQ results showed that the optimal order for Cataflam 50 Mg was made for 158 strips. By reordering the Cataflam 50 Mg medicine when the medicine stock reaches 15 strips in each product inventory which still has 23 strips remaining based on the ROP results.
