Pemisahan partikel-partikel tersebut dari umumnya dilakukan dengan menggunakan siklon. Konstruksi dan kondisi operasi siklon, seperti suhu gas yang masuk, berperan penting dalam menentukan kinerja pemisahan partikel dari gas tersebut. Penelitian ini bertujuan untuk mengkaji pengaruh perubahan suhu gas terhadap kinerja siklon dalam memisahkan partikulat dan tar dari gas-gas hasil gasifikasi tandan kosong kelapa sawit. Hasil kajian menunjukkan bahwa peningkatan suhu gas yang masuk ke siklon mampu memisahkan partikel berukuran 5–6 μm di kisaran suhu 200–300 °C pada efisiensi minimum 50%. Hasil perhitungan efisiensi pengumpulan rata-rata mencapai 98,23%, sedangkan hasil pengukuran adalah 85,56%. Hasil perhitungan dan ekperimen terhadap tekanan jatuh pada siklon, masing-masing, adalah 100,11 dan 87 mmH2 O, berada pada kisaran standar tekanan jatuh yang disarankan. Efisiensi dan tekanan jatuh yang diperoleh menunjukkan bahwa siklon dapat bekerja dengan baik. Hasil kajian menunjukkan bahwa siklon sebaiknya digunakan pada tahap awal dari proses pemisah partikel dari gas hasil gasifikasi, pada saat suhu gas masih tinggiKata kunci : Efisiensi Pengumpulan; Pengurangan Diameter; Penurunan Tekanan; Suhu Gas; Tar ABSTRACT Gas purification is one of a very crucial process required to be performed in order to obtain a better quality of gasses produced by grasification of oil palm empty fruit bunches. A cyclone is usually used in the purification process to separate particles and tarss from the gas. Particle separating performance of a cyclone is affected by its construction and operating conditions, such as temperature of the entering gas. The objectives of this study is to examine the effect of the entering gas temperature to the cyclone performance in separating particulates and tar from gases produced by gasification of oil palm empty fruit bunch. The results shows that the cyclone was capable in separating particles with size of 5-6 μm at entering gas temperature range of 200- 300 °C, at a minimum efficiency of 50%. The calculated average collection efficiency was 98.23% while the experimental results were 84.56%. Calculation and experimental data on pressure drop within the cylone was 100.11 and 97.0 mmH2 O, respectively, and fall within the required standard pressure drop. The collection efficiency and pressure drop indicated that the cyclone performed well. The study also suggests that cyclone is best to be used at the first row of the purification system for gases produced by gasification of empty fruit bunch since the temperature is still high enough Keywords : Collection Efficiency; Diameter Cut Size; Pressures Drop; Temperature of Gas; Tar

Abstract

The Koya West area is an agricultural center area in the city of Jayapura. After harvest, some of these agricultural products are sold directly to the market or to consumers, but some must go through a drying process, including corn, shallots and coconut. The drying process is still traditional, namely by relying on solar energy. Problems that occur when drying is done during the rainy season. In addition, the drying process requires a large area because the crops are just spread out on the ground with tarpaulin. In addition to being unhygienic, it will also be very inconvenient when it rains and farmers must save the crops that are in the sun so that they are not damaged. The purpose of this activity is to provide training and assistance in making dryers using UV plastic.

Abstract

Empty fruit bunches (EFB) are palm oil processing waste consisting of fibers and skins that still contain oil. EFB can be used as fuel for power plants or in the pyrolysis process to produce bio-oil, biogas and biochar. The test results showed various chemical contents of EFB and functional groups such as hydrocarbons, alcohols, aldehydes, acids, hydroxyl, carboxylates, ketones, chlorides, nitrates, nitriles, amines, phenols, hydrogen sulfide, sulfur and oxygen. The calorific value of EFB varies between 4,000 - 4,400 kcal or 16.6 - 18.48 kJ per metric ton. Pyrolysis at 400oC produces compounds with aliphatic and acyclic hydrocarbon groups, as well as a higher methane content.

Abstract

The addition of hydrogen through co-fuels can improve engine performance and efficiency. However, after a certain threshold, hydrogen begins to have side effects due to a decrease in the oxygen ratio of the fuel. The Generator hydrogen electrolyzer is a device that separates hydrogen and oxygen gases from water molecules using an electric current. The results of the refinement can be used as a power booster on the machine. The purpose of this study was to determine the effect of a generator hydrogen electrolyzer on gasoline engine performance. The method used is a comparison before and after using oxyhydrogen gas. The independent variables are 3 Amp, 4 Amp and 5 Amp loads, while the engine speed as the control variable ranges from 1000 rpm to 5000 rpm. The results show an increase in engine performance, such as an effective power of 18,21% at 4000 rpm, a decrease in fuel consumption of 15,34% at 3500 rpm, and an increase in thermal efficiency of 17,36% at 4000 rpm.

Abstract

In this study, testing on a single-cylinder air-cooled four-stroke gasoline engine started with a standard main jet diameter of 0.72 and main jet variations with diameters of 0.78, 0.85, and 0.95 mm. The test was carried out with a dynamometer at a wide-open throttle, around 75% of the gas valve opening (approximately 1600 rpm without load). Data collection for one test was carried out for 100 seconds by loading the incoming water with a dynamometer on the VDAS TecQuipment test equipment. The results of the research and data analysis carried out can be concluded to show that the use of main jet variations on a single-cylinder four-stroke gasoline engine can increase torque, effective power, average effective pressure, engine thermal efficiency, and fuel consumption (sfc). The optimal value is found in the use of the main jet variation of 0.95 compared to the standard main jet (0.72) with an average percentage increase of power of 5.42%, torque of 0.91%, Sfc of 24.98%, and bmep of 0.091, while thermal efficiency experienced the lowest decrease at 0.95 main jet by 40%.
