Abstract

In industry, the effective use of distribution channels is a key factor in reducing transportation costs. This research aims to optimize the product distribution routes of PT. Inbisco Niagatama Semesta (Mayora Group) using the Traveling Salesman Problem (TSP) Method. Product distribution is an important element in the supply chain, and this research can help improve operational efficiency and reduce company costs. Companies face various challenges such as variations in distribution quantities, capacity constraints, tight delivery times, and demand fluctuations. By analyzing distribution data, this research aims to find optimal distribution routes that minimize travel distance and distribution costs. The results of this research show that the shortest route obtained from calculations using the traveling salesman problem branch and bound method of WinQsb software obtained distribution delivery route results that had been calculated with a total distance of 88.40 km with a predetermined delivery route and obtained a total travel time of 132. 6 minutes and fuel consumption at a cost of Rp. 60.112

Abstract

Distilat asam lemak minyak sawit merupakan hasil samping dari pengolahan minyak sawit yang masih mengandung asam lemak bebas sehingga berpotensi sebagai bahan baku energi alternatif. Tidak dapat dipungkiri bahwa ketergantungan akan bahan bakar fosil semakin hari semakin meningkat, sedangkan bahan bakar fosil tidak dapat diperbaharui. Hal inilah yang mendorong para peneliti mengembangkan riset terkait bahan baku terbarukan dan metode terbaik untuk menghasilkan bahan bakar alternatif. Salah satu metode pembuatan biofuel adalah perengkahan katalitik yang menghasilkan beberapa produk biofuel, yaitu biogasoline (C5–C11), biokerosin (C12–C15) dan biodiesel (C16–C20). Tujuan dari penelitian ini adalah mengetahui pengaruh konsentrasi katalis HCl/γ-Al2O3 (1, 3, 5 dan 7)% dan HCl/Ni/γ-Al2O3 (1, 3, 5 dan 7)% terhadap produk biofuel hasil perengkahan katalitik distilat asam lemak minyak sawit (DALMs). Reaksi perengkahan katalitik dioperasikan pada suhu konstan 370oC, tekanan 1 atm dan volume reaktan 50 ml. Rendemen tertinggi diperoleh sebesar 80% dengan menggunakan katalis HCl/γ-Al2O3 (1%) ; selektivitas terhadap biogasoline (C5–C11) 5,27%, biokerosin (C12–C15) 30,4%, dan biodiesel (C16–C20) 28,79%. Perolehan nilai rendemen yang sama juga diperoleh dengan menggunakan katalis HCl/Ni/γ-Al2O3 (1%) yaitu sebesar 80%; selektivitas terhadap biogasoline (C5–C11) 4,51%, biokerosin (C12–C15) 28%, dan biodiesel (C16–C20) 37,3%.

Abstract

The manufacturing industry, including the refined sugar industry, faces challenges in minimizing environmental impact and enhancing operational sustainability. The implementation of the green manufacturing concept is essential to achieving these goals. This study aims to evaluate the green manufacturing performance of PT. ABC, focusing on environmental, economic, and social aspects. The research methodology employed is a qualitative and quantitative descriptive analysis using relevant frameworks and metrics based on the Green SCOR. The findings indicate that PT. ABC has implemented several green manufacturing practices; however, there are still areas that need improvement, such as high energy consumption and a high defect rate. This study provides recommendations to enhance green manufacturing performance at PT. ABC, including optimizing energy use, reducing waste, and improving production process efficiency. The results of this study are expected to serve as a reference for PT. ABC in developing strategies and improvement plans to achieve better operational and environmental sustainability.

Abstract

The development of the era where everything is instantaneous and fast as it is today must be supported by the development of increasingly sophisticated information technology. One of the functions of this technological development is to obtain accurate and fast information. But in fact, there are still companies / organizations that have not used computer technology as a work aid, such as the Bromo Rajawali Convection which still uses the manual method of writing employee data, namely data storage still using books. Therefore, the design of an employee data management information system is carried out that can help companies control the production data of each tailor employee. The method used in this research is the Waterfall method. It is called a waterfall because the steps that are passed must wait for the completion of the previous stage and run sequentially, for example the design stage must wait for the completion of the previous stage, namely the requirements stage [1]. The Waterfall method consists of 5 stages, namely Analysis, Design, Coding, Testing and Maintenance. The purpose of this study is to design an information system that can make it easier for companies to write down employee production data accurately. From the design results, there are two factors that support the running of the system, namely administration and production data, the input form available on the system that has been designed, namely the login input form and the employee data input form, while the output form contains complete data related to employee personal data and employee production data. With the creation of a management information system in writing data on employee production, the Rajawali Bromo Convection can accelerate the search for more accurate data in the future, and applications made later by the company can be used properly as one of the employee production data systems

Abstract

PT. Vale Indonesia Tbk. is a company engaged in the mining industry, particularly in nickel processing (Ni). The company operates a power plant at Balambano Hydroelectric Power Plant (2x68.5 MW). The company's usual maintenance practice is limited to corrective maintenance, which involves replacing or repairing components only when they are damaged. The aim of this research is to determine the optimal replacement time for preventive maintenance on turbine machines in order to minimize downtime. The age replacement method is used to calculate the replacement interval for components based on their usage life. The research findings show that the mean time to failure (MTTF) of the wicket gate is 2217.824 hours or 92.41 days, which means that the component may experience failure again after operating for that MTTF duration. Therefore, the recommendation is to replace the component every 85 days of operation and perform inspections every 15 days.
