Abstract

The purpose of this study was to determine the manufacturing process on PT XYZ's primary and secondary machines using the Linear Programming method. This causes that in each period, the company experiences excess and decrease in production so that the company's profit is not optimal and results in large holding costs. This situation occurs because the company has been implementing production planning based on core. The method used as a solution is Linear Programming. The research method used is qualitative and descriptive methods and data collection techniques for library studies through various literature such as journals, books, magazines, articles obtained through Google Scholar with the keywords used namely manufacturing keywords, primary and secondary machines, and linear programming methods. so as to obtain accurate and in-depth data regarding the manufacturing process with the linear programming method. The results showed that the manufacturing process on PT XYZ's primary and secondary machines using the linear programming method could be more efficient in the use of existing resources and the policies implemented. So that feelings related to product combinations and changes related to profit per product with the loss of resources.

Abstract

Currently, the Temporary Waste Collection Point (TPS Tombro) faces challenges in implementing a waste processing system based on the 3R principle (Reduce, Reuse, Recycle). While there are sorting facilities, the inorganic waste sorting largely depends on scavengers, and there is no organic waste processing. This research aims to analyze the waste management system at TPS Tombro, focusing on its infrastructure, supporting facilities, and capacity to accommodate waste from the surrounding area. Data collection was conducted through interviews, field observations, and waste transport surveys. The results show that although some of the infrastructure and facilities are underutilized, TPS Tombro can still manage the waste generated in its service area without significant accumulation. The study also provides quantitative data on the daily waste volume and compares the capacity of TPS Tombro with the generated waste. The analysis reveals potential areas for improving the waste management process, ensuring greater efficiency and sustainability

Abstract

This study focuses on evaluating fire protection systems at gas stations, which are vital infrastructure for fuel supply. The main objective of this study is to assess the availability of fire protection systems and the need for fire extinguishers to minimize the risk of fire. The methods applied include a quantitative descriptive approach through field observations, interviews, and documentation studies. The results show that gas stations have adequate supplies of water and light fire extinguishers. However, active protection systems, including fire detectors, sprinklers, and hydrants, are still inadequate, with a recorded reliability rate of only 24% and field facility completeness reaching 11.7%. For passive protection and evacuation facilities, the scores were 18.79% and 22.45%, respectively, which were considered quite good. These findings recommend the installation of at least three 9 kg fire extinguishers, four pillar hydrants, and thirty sprinkler points. By implementing these recommendations, it is hoped that gas stations can improve the safety of service users and reduce the risk of fire, as well as comply with existing safety regulations. This study is expected to serve as a reference for gas station managers and related parties in their efforts to improve fire protection and safety systems at public fuel supply facilities.
