Abstract

Vegetable oil is one of the alternative sources of raw material for fuel oil to produce biodiesel. The conversion reaction process requires the help of a catalyst to break down triglycerides into methyl esters. Therefore, this study aims to determine the performance of catalysts made from coconut shells to convert bulk oil into biodiesel. The catalyst performance is focused on biodiesel's yield parameters through the influence factor of catalyst weight, molar ratio, and %FAME. This research was conducted in three stages, namely (1) catalyst preparation, (2) application of catalyst performance through the conversion process of bulk oil into biodiesel, (3) washing of biodiesel. The first stage was catalyst preparation carried out by utilizing a coconut shell, which was first made into charcoal, then activated using H3PO4 then sulfonated with H2SO4. The second stage was the conversion process of bulk oil into biodiesel using coconut shell catalysts through a transesterification process using variations in the catalyst's weight to bulk oil (0.5; 1; 1.5; 2; and 2.5% wt/wt) and bulk oil molar:methanol ratio (1: 3; 1: 6; and 1: 9). The third stage was the process of washing biodiesel using HCl. Based on this study's results, the best catalyst weight was 2% wt/wt with a molar ratio of 1: 9 resulting in the highest yield of 89% and the FAME of 80.36%.

Abstract

Penelitian ini membahas pentingnya menentukan waktu nyala pada briket arang dengan mempertimbangkan variabel perekat dan ukuran mesh bahan. Metode penelitian yang digunakan adalah metode eksperimental, di mana waktu nyala diukur dari saat briket dinyalakan hingga padam sepenuhnya dengan variasi perekat dan ukuran mesh bahan. Hasil penelitian ini dapat diterapkan dalam kehidupan sehari-hari, seperti dalam pemilihan briket arang, pengembangan produk, pendidikan, dan konservasi energi. Selain itu, penelitian ini juga memberikan rekomendasi untuk penggunaan briket arang dan cara memeriksa kualitasnya sebelum digunakan. Hasil penelitian menunjukkan bahwa variabel ukuran mesh bahan memiliki pengaruh signifikan terhadap waktu nyala. Pada penelitian ini ukuran mesh 60 memberikan penyalaan awal lebih baik yang ditunjukkan dengan luas area nyala paling luas dan durasi nyala paling lama. Jumlah perekat yang sedikit memberikan warna sisa pembakaran yang paling baik

Abstract

This community service program aims to strengthen the managerial capacity of red lemongrass farmers in AMKE Oro-Oro Ombo, Batu, East Java, through training on cash bookkeeping, income analysis, and farming feasibility evaluation. The main problems faced by farmers are limited knowledge of financial management, lack of systematic bookkeeping, and inability to evaluate the profitability of their businesses, which often results in inaccurate decision-making and low competitiveness. The method applied included participatory training, mentoring, and simulation of financial records and feasibility analysis. The results of the program demonstrate that participants gained a better understanding of the importance of structured financial recording. Farmers who previously relied only on sales revenue calculations without considering fixed and variable costs are now able to prepare cash books, identify expenses, and evaluate profit margins accurately. Cash bookkeeping has proven to improve financial transparency and accountability, while income analysis has equipped farmers with the skills to assess their business sustainability. The feasibility evaluation, using indicators such as R/C and B/C ratios, showed that red lemongrass farming is profitable but still requires efficiency improvements to increase long-term sustainability. Overall, this training has enhanced farmers’ managerial skills, encouraged independent decision-making, and strengthened their capacity to face price fluctuations and market competition. The program is expected to support the continuity and competitiveness of red lemongrass agribusiness in AMKE Oro-Oro Ombo
