Abstract

Occupational Safety and Health (OSH) is a critical aspect of agricultural activities that is often overlooked by farmers, particularly in rural communities. In Waturempe Village, West Muna Regency, most farmers depend on patchouli (Pogostemon cablin) as the primary raw material for essential oil production. However, manual patchouli processing not only results in low productivity and suboptimal yield quality but also exposes farmers to a high risk of workplace accidents. This community service project was designed to: (1) provide education and promote the implementation of OSH among farmers, (2) introduce and train farmers in the use of patchouli chopping machines as an appropriate technology, and (3) enhance farmer welfare by improving efficiency and productivity. The program was carried out through OSH awareness sessions, technical training on machine operation, and field assistance. The outcomes demonstrated an increase in farmers’ knowledge of OSH, improved skills in operating the machines, and up to a 60% increase in chopping efficiency compared to manual methods. Moreover, the more uniform chopping quality contributed to better essential oil quality. Overall, this initiative made a significant contribution to enhancing productivity, income potential, and the welfare of local farmers.

Abstract

This study evaluates the potential of Kendari Bay sediment as an alternative source of electrical energy through the dual-chamber Sediment Microbial Fuel Cell (SMFC) technology. The research focused on sediment characterization, performance analysis using an aerator and KMnO₄, post-operation substrate changes, and the identification of electrogenic bacteria. The results showed that the sediment contained 43.24% moisture, 4.23% organic carbon, 1.08% total nitrogen, a C/N ratio of 3.92, pH 7.38, and conductivity of 11.56 mS. The SMFC generated a voltage of 0.404 V (aerator) and 1.628 V (KMnO₄), along with a current of 5.0 µA. After SMFC operation, organic content decreased, with 42.65% moisture, 4.06% organic carbon, 0.97% total nitrogen, a C/N ratio of 4.19, pH 7.86, and conductivity of 15.78 mS. Identified bacteria were Gram-positive Bacillus spp. These findings demonstrate that aerator and KMnO₄ application in dual-chamber SMFC significantly enhance energy conversion efficiency using marine sediment.

Abstract

Penelitian ini membahas penggunaan untuk membandingkan efisiensi Bioetanol dengan bahan bakar Pertalite. tujuannya adalah untuk mengetahui penggunaan ECU standar dan ECU Programmable setelah pengujian driving cycle.  Dengan Metode eksperimen yang digunakan untuk  pengujian di lapangan dan analisis data konsumsi bahan bakar berdasarkan jarak tempuh dan waktu. Data input yaitu RPM, TPS, Torsi Konsumsi bahan bakar, dan Fuel. Data output yaitu Ignition Timing dan Injection Timing. Untuk mendapatkan hasil konsumsi bahan bakar yang efisien melibatkan pengaruh variasi campuran pada bahan bakar Bioetanol terbaik dengan persentase bahan bakar Pertalite 95% dan Bioetanol 5% menghasilkan 0.15 ml/s. Hasil penelitian menggunakan bahan bakar Pertalite 0%  menghasilkan 0.01 ml/s. Tetapi tidak mendapatkan efisiensi pada bahan bakar jenis Bioetanol dari ECU Programmable. Penelitian ini menunjukan bahwa dapat digunakan untuk memprediksi nilai efisiensi pada pengapian motor sistem injeksi untuk mendapatkan bahan bakar yang efisien.
