Abstract

Along with advancements in mechanical engineering technology for fishing vessel, particularly in diesel engines, numerous developments have been made to achieve maximum performance. This study aims to determine the effect of applying an exhaust gas recirculation (EGR) system on the performance of diesel engines using B40 biodiesel fuel. The use of biodiesel as an alternative fuel is growing because it can reduce dependence on fossil fuels and reduce exhaust emissions. However, the use of high-blend biodiesel such as B40 can affect combustion characteristics and engine performance. Therefore, a method is needed to optimize engine performance, one of which is through the application of an EGR system. The research method was conducted experimentally by testing diesel engines using B40 biodiesel fuel. The testing was carried out directly by operating diesel engines equipped with EGR systems. The parameters observed included engine performance, such as power and specific fuel consumption. Data was collected under varying load conditions. The data obtained was then analyzed to determine the effect of EGR on engine performance improvement. The results indicate that the application of an exhaust gas recirculation system in diesel engines utilizing B40 biodiesel fuel can influence the combustion process, thereby affecting engine performance. At a valve opening of 25%, the best SFOC can be achieved. The results showed that the application of an exhaust gas recirculation system in diesel engines using B40 biodiesel fuel can affect the combustion process, thereby impacting engine performance. Based on the test results, it can be concluded that the application of an exhaust gas recirculation (EGR) system in diesel engines fueled by B40 biodiesel improves engine efficiency.

Abstract

Keterampilan masyarakat nelayan di Pelabuhan Cituis, Desa Surya Bahari, Kabupaten Tangerang, dalam menangani potensi bahaya kebakaran pada kapal tradisional. Kapal nelayan tradisional di wilayah ini memiliki risiko kebakaran yang tinggi akibat penggunaan bahan bakar minyak (BBM), aktivitas memasak di atas kapal, serta kondisi mesin yang sering kali sudah tua dan tidak terawat. Masalah utama yang dihadapi adalah rendahnya kesadaran nelayan akan prosedur keselamatan dan minimnya ketersediaan Alat Pemadam Api Ringan (APAR) di atas kapal. Metode yang digunakan meliputi penyuluhan teoretis mengenai penyebab dan pencegahan kebakaran, sesi tanya jawab interaktif, serta praktik simulasi pemadaman api menggunakan APAR yang dipandu oleh para cadet mahasiswa. Hasil kegiatan menunjukkan adanya peningkatan pemahaman peserta yang signifikan mengenai langkah-langkah darurat dan cara pengoperasian alat pemadam kebakaran. Melalui pelatihan ini, nelayan kini merasa lebih percaya diri dan proaktif dalam menjaga keselamatan diri serta aset kapal mereka selama beroperasi di laut.   This community service activity aims to improve the knowledge and skills of the fishing community at Cituis Port, Surya Bahari Village, Tangerang Regency, in handling potential fire hazards on traditional ships. Traditional fishing vessels in this region carry a high risk of fire due to the use of fuel oil (BBM), cooking activities on board, and the condition of engines that are often old and poorly maintained. The main problem faced is the low awareness of fishers regarding safety procedures and the minimal availability of fire extinguishers (APAR) on board. The methods used include theoretical counseling on the causes and prevention of fires, interactive Q&A sessions, and fire-fighting simulation practices using fire extinguishers guided by student cadets. The results of the activity showed a significant increase in participants' understanding of emergency steps and how to operate fire-fighting equipment. Through this training, fishers now feel more confident and proactive in maintaining their personal safety and ship assets while operating at sea.
