Abstract

The increasing need for energy and dwindling natural reserves encourage the search for alternative energy sources. One alternative energy source is biodiesel. Biodiesel can be produced from used cooking oil through the esterification and transesterification processes. However, biodiesel sourced from plant materials has disadvantages, one of which is its low calorific value. Most studies discuss the addition of chemical additives to increase the calorific value of biodiesel. However, the addition of ethanol vapor as an air additive to increase the calorific value of biodiesel is rarely discussed. This study was conducted experimentally, the study examined the effect of adding ethanol vapor to a diesel engine through an air filter. The diesel fuel used was dexlite type diesel fuel added with biodiesel from used cooking oil as much as 10% to 30%. Testing used additional ethanol vapor channeled through an air filter with a heating temperature of 90oC to 100oC. The results of the study were in the form of crankshaft rotation, effective power, and fuel consumption. The results showed that fuel with the addition of ethanol vapor produced the highest crankshaft rotation, effective power, and fuel consumption when compared to without the addition of ethanol vapor in all variations of the given fuel composition. The highest value of crankshaft rotation, effective power is in the B0 composition with values ​​of 32.53 rev/s and 2.74 kW, respectively. While the lowest fuel consumption is in the B70 composition with the addition of ethanol vapor of 105.7 seconds.

Abstract

This study aims to evaluate the impact of RLC loading on the power stability and power quality in Wind Power Plant (PLTB) systems. The RLC is applied to stabilize the power generated by the PLTB system, which tends to fluctuate due to wind speed variability. The testing was conducted by measuring the output power of the PLTB system loaded with various RLC configurations. The results show that RLC loading can enhance the apparent power stability and efficiency of the PLTB system. The resistive load (R) yielded the best performance, improving the power factor to 0.95 and maintaining relatively stable output voltage. Meanwhile, the LC loads exhibited lower efficiency with a reduced power factor, but still played a role in balancing reactive power. The reduction in reactive power for inductive and capacitive loads indicates that RLC loading can help reduce power waste and improve power quality. This research makes a significant contribution to the development of more efficient and stable PLTB systems and more reliable renewable energy-based power plants, particularly in managing power stability in the face of fluctuations caused by wind variability.

Abstract

Pemanfaatan material komposit berbasis serat alami saat ini menjadi topik penelitian yang menarik dalam industri maritim. Selain ramah lingkungan, serat alami juga dapat menggantikan serat sintesis. Selain itu, serat alami dapat diaplikasikan pada industri maritim yaitu pada kapal tradisional. Salah satu jenis serat alami adalah serat kelapa, yang saat ini menjadi limbah pertanian dan belum termanfaatkan dengan optimal. Jika ditinjau dari keberadaanya sebagai bahan baku serat alami maka serat kelapa memiliki jumlah yang berlimpah. Serat kelapa memiliki sifat mekanik yang potensial sehingga menjadi salah satu kandidat bahan baku serat alami untuk aplikasi industri maritim. Tujuan penelitian ini adalah menganalisis pendekatan fabrikasi penggunaan serat kelapa dengan struktur mikro dan lentur menggunakan metode vacuum infusion. Untuk meningkatkan daya ikat terhadap matriks resin polyester serat kelapa diberi perlakuan alkalisasi dengan larutan NaOH 5% selama dua jam. Variasi pada penelitian ini adalah arah serat dengan arah 0°/90°, 60°/–60°, 45°/–45°, dan 30°/–30° dengan setiap sampel empat lapis. Pengujian yang dilakukan adalah uji bending dan uji struktur mikro. Uji bending dilakukan berdasarkan standar ASTM D790 menggunakan metode three-point bending sedangkan uji struktur mikro dilakukan melalui Scanning Electron Microscopy (SEM). Hasil pengujian menunjukkan bahwa arah 30°/–30° menghasilkan nilai terendah sebesar 56,55 MPa sedangkan arah serat 0°/90° menghasilkan kekuatan lentur tertinggi sebesar 90,35 MPa tertinggi. Pengamatan SEM juga menunjukkan adanya celah dan fiber pull-out yang mengindikasikan area peningkatan pada teknik fabrikasi.
