Abstract

Penelitian ini dilakukan untuk memberikan penjelasan tentang studi eksperimental pengaruh variasi beban dan variasi aliran terhadap efek water hammer. Dimana efek ini akan mempengaruhi tekanan air yang akan dihasilkan jika setelah pembebanan dan perubahan bukaan valve yang diberikan akan menghasilkan efek water hammer yang lebih baik atau cenderung lebih buruk bila tidak memiliki kedua efek tersebut. Penelitian ini dilakukan dengan melakukan studi eksperimental yang bertujuan untuk mengetahui tekanan yang terjadi pada saat air mengalir dan kemudian ditutup secara tiba-tiba oleh katup pembuangan yang dihubungkan dengan aliran pipa dengan diameter 1,5 inci setelah beban dan variasi bukaan katup. Pada uji efek water hammer dengan sistem pompa water hammer hidrolik ini dimungkinkan untuk mengubah bukaan katup pemasukan air dengan perubahan beban katup yang diberikan untuk menentukan tekanan water hammer maksimum 378334,64 Pa setelah menerima katup bukaan 80 derajat dan tambahan beban 250 gr, dan efek water hammer terkecil dengan nilai 321376,44 Pa pada bukaan katup 50 derajat dan beban 150 gr. Saat menginvestigasi pompa hydraulic ram ini, dapat disimpulkan bahwa ukuran bukaan valve atau jumlah air yang masuk dan besarnya beban pada discharge valve yang akan mempengaruhi tekanan akan meningkat.

Abstract

The working system of the heating process on a plastic injection molding machine needs to be considered in more detail. Due to the influence of temperature and the type of material according to the quality of the product. In this study, the plastic injection machine that used a temperature variation used several different variations, and three experiments were given at each temperature variation of 200°C – 250°C using 75 grams of plastic material with a heating time of 120-141 seconds and 150 grams of plastic material with a heating time of 120-141 seconds. Warm-up 210-250 seconds. Temperature control using the REX C100 Controller. The injection machine can operate according to the design. Namely, the heating temperature can be adjusted. Implementation and control of the control system show a good response. The plastic to be melted is of the HDPE (High-Density polypropylene) type with a temperature for melting the plastic of 250°C.

Abstract

The food drying process is an innovative method to change the process of reducing the water content of fresh food products of plant origin to slow down the emergence and growth of unwanted microorganisms. This heating system has four heating elements, where the heating elements used have a power of 1200W because each heating element has a power of 300W. During the drying process, it is known that the average air temperature in the drying room is higher when using solar energy compared to a heating system. The average temperature measurement during the day is 38°C. The measurement results tend to be constant, with an average of 34°C for 7 hours using the heating system. The battery voltage shows an increase every hour. At 08:30 am the battery voltage was 12.3V, and until 16.00 the voltage was 13.57V. This dryer is sourced from solar energy because using solar for drying requires a longer time, namely 8 hours (08.30-16.00), compared to using a heating system for 7 hours.

Abstract

Biofuels include energy-enriched chemicals produced directly through biological processes or derived from the chemical conversion of the biomass of previously living organisms. Biofuels can be classified into two categories: primary and secondary biofuels. The main biofuels are produced directly from burning woody plant material or cellulose and dry animal dung. Secondary biofuels can be classified into three generations, and each is produced indirectly from plant and animal materials. The first-generation biofuel is ethanol derived from starch-rich food crops or biodiesel, extracted from animal fat wastes such as cooking oil. The second generation is bioethanol derived from non-food cellulosic biomass and biodiesel derived from oil-rich plant seeds such as soybean or jatropha. The third generation is a biofuel produced from cyanobacteria, microalgae, and other microbes, which is the most promising approach to meet global energy demand. This community service aims to explain innovation and provide knowledge to technology players, namely technicians, operators, supervisors, and workshop supervisors, about the use of alternative fuels of sesame oil for small-capacity automatic gasoline engines. The counseling results show that the performance and exhaust gas results are optimal so that the technology actors know the quality and quantity of the alternative energy.

Abstract

Butanol as a fuel has a high oxygen content, so the combustion process will be more friendly to the environment. In this study, butanol will be mixed with RON-90 gasoline with a capacity of 5% (B5); 7%(B7); 10%(B10); 12%(B12); 15%(B15) and 18%(B18). The engine used is an automatic transmission with a capacity of 109.5cc with a compression ratio of 9.5:1. The test equipment for engine performance and exhaust emissions is the 50L BRT Super-Dyno and EPSG4 Gas Analyzer. The results showed that using B18 fuel for CO exhaust emissions decreased by 44% at an engine speed of 6000rpm. CO2 exhaust emissions have decreased by 47% at 8000rpm engine speed. HC exhaust emissions have decreased by 28% at 9000rpm engine speed. In contrast to NOx emissions, which increased by 22% at 9000rpm engine speed, this was due to the increasing temperature in the combustion chamber.

Abstract

Acetone-butanol-ethanol (ABE) is a preferred alternative energy for SI engines. This research uses an experimental method with an automatic SI engine, RON-90 fuel mixed with ABE1 (12:8:1)v/v, ABE2 (15:10:1)v/v and ABE3 (1i8:12:1) v/v. Engine speed is 4000-10000rpm, and compression ratio is 11.6:1. Emission and engine performance testing used EPSG4-Gas analyzer and Dynotest-chassis type 50L-BRT. This research aims to explore the mixture of RON-90 and ABE to optimize performance and exhaust emissions. This research shows that torque increases by an average of 14.7% at an engine speed of 6000rpm. Power increased significantly with an average value of 9.5% at an engine speed of 8000rpm, MEP increased by 0.5%, and thermal efficiency increased by 7%. SFC experienced a fairly optimal decrease of 15.6% on average. The exhaust gas emissions produced are CO and HC. The reduction in CO and HC occurred in the ABE3 variant with values of 8.2% and 1.6%, respectively.
