Abstract

Soy methyl ester merupakan salah satu contoh bahan bakar hayati (biofuel) yang memiliki potensi besar sebagai pengganti atau tambahan bahan bakar diesel. Biofuel adalah jenis bahan bakar yang berasal dari sumber organik, baik dalam bentuk cair, padat, maupun gas. Penelitian ini bertujuan untuk menganalisis performa dan efisiensi penggunaan bahan bakar diesel dan soy methyl ester. Analisis dilakukan pada sistem permesinan Kirloskar AV1 dengan menggunakan bahan bakar diesel dan soy methyl ester, melalui simulasi menggunakan perangkat lunak Diesel RK. Penelitian ini memfokuskan pada empat parameter utama, yaitu daya mesin, konsumsi bahan bakar, tekanan rata-rata efektif rem (brake mean effective pressure), dan efisiensi mesin piston. Hasil penelitian menunjukkan bahwa penambahan soy methyl ester menyebabkan penurunan daya mesin, tekanan rata-rata efektif rem, dan efisiensi mesin piston. Namun, peningkatan konsumsi bahan bakar terlihat sebagai tren yang konsisten ketika soy methyl ester ditambahkan.

Abstract

Used cooking oil is cooking oil that is no longer suitable for use because it has undergone changes in physical and chemical properties during the frying process. Used cooking oil is a hazardous and toxic waste; consuming it can cause negative impacts on health and disposing of it carelessly can cause environmental pollution. However, public knowledge about the dangers and impacts of used cooking oil is still minimal. A study showed that there are still many people who dispose of used cooking oil on the ground and waterways. Therefore, the activity designed by the PKM team of Universitas Pembangunan Nasional Veteran Jakarta aims to increase public knowledge about the dangers and impacts of used cooking oil and provide solutions to reduce the pollution of used cooking oil waste. This activity was carried out in the Grand Pakis Residence housing complex using socialization and training methods. In this activity, the PKM team invited representatives from the Jalantara foundation as speakers to explain the impact of used cooking oil on the environment and health to the community. Not only that, the community was also given a training on processing used cooking oil into other products as a solution to reduce used cooking oil waste. The result of this activity is that the knowledge of residents about the dangers of used cooking oil for the environment and health has increased by 80.95%. In addition, the residents also know how to reduce used cooking oil by turning it into useful products such as soap.

Abstract

Kavitasi pada valve merupakan fenomena yang sering terjadi di lingkungan kapal yang dapat menyebabkan kerusakan pada sistem perpipaan dan komponen terkait. Para owner kapal kerap menganggap sepele permasalahan kavitasi ini sehingga valve kerap tidak beroperasional dengan baik karena terjadinya kavitasi. Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan teknologi anti kavitasi terhadap fenomena kavitasi pada Sea Chest Valve. Metode yang digunakan meliputi pengumpulan data lapangan dari kapal yang beroperasi secara rutin, serta simulasi menggunakan software Valvstream untuk mengetahui efektivitas penambahan trim anti kavitasi. Studi ini bertujuan untuk menganalisis efektivitas Trim anti kavitasi pada Sea Chest Valve dengan variasi pressure, temperature, sound level, dan viscosity serta membuat prototype valve yang terpasang trim anti kavitasi. Analisis simulasimenunjukkan bahwa penurunan tekanan, kenaikan temperature, sound level yang tinggi dan viscosity yang tinggi sebagai indikator terjadinya kavitasi dapat berkurang dengan ditambahkan nya anti kavitasi. Penelitian ini memberikan kontribusi dalam memahami mekanisme kavitasi pada aplikasi Sea Chest Valve di kapal serta memberikan rekomendasi untuk pengembangan teknologi anti kavitasi di masa depan. Implikasi praktis dari penelitian ini adalah potensi untuk meningkatkan keandalan dan masa pakai sistem perpipaan pada kapal, serta mengurangi terjadinya kavitasi.

Abstract

The growing need for renewable energy has driven significant interest in harnessing ocean wave power, particularly through Oscillating Wave Surge Converters (OWSCs). This study focuses on examining the effect of flap width on the hydrodynamic capacity of an OWSC, as flap geometry plays a crucial role in energy capture efficiency. A numerical methodology utilizing the Boundary Element Method (BEM) was employed to assess hydrodynamic parameters across both temporal and frequency domains. Five flap width variations were tested under regular wave conditions with different periods, while mesh independence and validation against experimental data ensured accuracy. The results in the time domain revealed a direct correlation between flap width and angular deviation, velocity, torque, and power output, although wider flaps exhibited less stability due to increased inertia. Frequency domain analysis indicated that each flap width had a distinct resonant peak, with narrower flaps performing best at shorter periods and wider flaps at longer ones. Notably, moderately sized flaps (W2 and W3) achieved the highest efficiency, with Capture Width Ratios exceeding 70%, outperforming wider flaps despite their larger surface area. These findings highlight the importance of optimized flap width for efficient and reliable OWSC design.
