Abstract

Blending fuels is an urgent alternative to reduce dependence on gasoline. Blending gasoline-alcohol bioethanol is realistic due to its high octane number properties and the abundant availability of raw materials. However, high viscosity results in inconsistent fuel mixing homogenization and decreased injector performance. The research aims to design a Dual Port Injection scheme as a dummy simulation of fuel blending so that bioethanol alcohol can be homogeneously blended with gasoline in the combustion chamber. The method used is observation of the Electric Fuel Injection working system and designing a Dual Port Injection Scheme. The research resulted in a Dual Port Injection scheme with the concept of doubling the injection-based fuel system and commands from the commercial Electric Control Unit to be forwarded to the bioethanol and bioethanol fuel pumps to supply fuel to the high pressure pipe.

Abstract

Dependence on fossil fuels requires a solution through alternative fuels. Ethanol is the recommended solution because it is easy to produce using raw materials that are abundant in nature, such as mangrove fruit. The Rhizophora Mucronata type of mangrove fruit contains 45.22% carbohydrates and is not used as raw material for human food. The research aims to produce ethanol biofuel from mangrove raw materials using multistage distillation. Experimental methods were applied at the stages of mangrove flour production, mangrove flour property testing, saccharification and fermentation, mangrove ethanol distillation, and analysis of potential performance and exhaust emissions. The research produced mangrove biofuel with an alcohol content of 28% which was produced from mangrove flour and had an ash content of 1.91%, protein, 2.24%, fat 0.53%, and water 11.61%. In addition, mangrove biofuel has higher viscosity and density properties than Gasoline at 0.8067Cp and 0.8115 g per mL respectively. The use of mangrove biofuel as a result of experiments is predicted to reduce fuel injection performance.

Abstract

The use of gasoline in vehicles produces CO, HC, and NOx emissions which are dangerous for the environment. Using butanol and ethanol as additional gasoline can reduce pollutant emissions. This is because alcohol has a high oxygen content and helps combustion more completely. This research compares the Exhaust Gas Temperature and Emissions results of EFI engines using gasoline-butanol and gasoline-ethanol. The EFI engine used has a capacity of 150CC. The alcohol used was butanol and ethanol with a percentage of 5%, 10%, and 15% in each test. The test results showed that the highest EGT reduction occurred in the E15 mixture at 23.98% and B15% at 8.65. Meanwhile, CO emissions experienced the highest reduction in E10 by 53.6% and B15 by 44.6%. HC emissions also experienced the highest reduction in E15 by 70.5% and B15 by 66.7% compared to gasoline. However, CO2 emissions increased to 17.07% in the E15 mixture and 11.46% in B15. This proves that the addition of ethanol produces more complete combustion than the addition of butanol.

Abstract

The use of fossil fuels causes air pollution in Indonesia. Biofuel is one of the alternatives often used, one of which is methanol. Methanol has efficient characteristics and low emissions, increases engine performance and thermal efficiency, and reduces fuel consumption. This study aims to observe the concentration of pertamax - methanol addition of 5%, 10%, and 15% on performance, BSFC, and BTE. The percentage of pertamax and methanol fuel mixing is 5%, 10%, and 15%, and the speed used is 1000, 2000, and 3000 rpm. The measurements taken are power, BSFC, and BTE using a dynotest and displayed on a screen. Adding 5%, 10%, and 15% methanol to pertamax increases engine performance. The addition of Pertamax-methanol PM15 increases power by 25% at a speed of 1000 rpm, reduces BSFC by 40% on PM15 at a speed of 2000 rpm, and increases thermal efficiency on PM5 by 73% at a speed of 2000 rpm

Abstract

Alternative fuels are a priority to reduce the problem of fuel stock shortages. Bioethanol has potential because of its octane number specifications, oxygen content, and simple production techniques. Mangrove bioethanol is produced from mangrove fruit, which is non-edible and abundant. This study aims to observe the correlation of Mangrove Biofuel specifications (mixture of gasoline and 5% Mangrove Bioethanol) to Brake Torque and NOx Emissions produced by gasoline engines. Experimental methods are applied, from Mangrove Bioethanol production, octane value, oxygen content testing, and Mangrove Biofuel production to performance and emission testing. The results of the study showed that the correlation of the 101 octane number specifications and 30.31% oxygen content of Mangrove Biofuel increased the highest Brake Torque, reaching 5.45%, and increased the highest NOx emissions up to 6.54% at engine speeds of 5000 rpm.

Abstract

The energy crisis is largely attributed to the extensive use of fossil fuels. Butanol and ethanol can be used as an alternative energy source because their characteristics are superior to those of gasoline, such as RON and oxygen content. This study aims to determine the effect of gasoline-butanol and gasoline-ethanol mixtures on engine performance so that they can be an option to replace fossil fuels. The percentage of alcohol (butanol and ethanol) in gasoline is 5%, 10%, and 15% with variations in engine speed of 1000, 2000, and 3000 rpm. This study uses a dynamometer as a tool to measure engine performance. Test results show that E15 can increase engine torque and power by up to 26%, while B15 increases by 19%. In addition, ethanol can reduce BSFC better than butanol. The BSFC value decreased by 17% in E15, while B15 decreased by 15% compared to pure gasoline. This is because ethanol's RON and oxygen content are higher, so torque and power increase while BSFC decreases. These results prove that gasoline-ethanol is better at improving engine performance than gasoline-butanol.

Abstract

Dunia industri pelapisan logam mengalami peningkatan yang sangat cepat, mulai dari pelapisan bahan, jenis pelapisan hingga hasil dari pelapisan tersebut. Untuk menanggulangi bahaya kerusakan pada logam salah satunya korosi diperlukan cara untuk melindunginya yaitu dengan menggunakan pelapisan logam salah satunya electroplating. Baja ST41 adalah salah satu dari baja karbon rendah. Baja ini termasuk dalam golongan baja karbon rendah karena dalam komposisinya mengandung karbon sebesar 0,08%-0,20%. Prosedur penelitian yang akan dilakukan dalam penelitian ini yaitu dengan cara memotong benda kerja baja ST 41  yang berdiameter 40 mm dengan panjang 20 mm sampai jumlah total 14 spesimen dilakukan electroplating menggunakan variasi 5 V dan 10 V serta mengggunakan variasi waktu 15, 30 dan 45 menit. Hasil  electroplating pada tegangan 5 volt dan 10 volt memperlihatkan bahwa ketebalan terendah berada pada waktu 15 menit sebesar  tegangan 5 Volt sebesar 2,316 µm dan ketebalan tertinggi pada waktu 45 menit tegangan 10 volt  dengan tingkat ketebalan 7,93 µm. Hasil kekerasan pada baja ST 41 tegangan 5 dan 10 volt memperlihatkan bahwa tingkat kekerasan  terendah pada variasi waktu 30 menit tegangan 5 Volt sebesar 147 HB dan nilai kekerasan tertinggi pada variasi waktu 45 menit tegangan 10 volt sebesar 170 HB

Abstract

Vocational High School (SMK) graduates are the biggest contributor to the unemployment rate. The Tegal Indonesia Bintang Manufaktur Job Training Institute helps increase the knowledge and skills of participants who incidentally are class XII SMK. Class XII who graduate in 2023 will certainly have low knowledge and competence because of the learning method used online (Covid-19 pandemic policy). The community service program (PKM) aims to strengthen basic competence, especially measuring. The method used is Training which is held for three days (20-22 March 2023). The results of PKM presented increase in measuring competency of 95.38% from 32 participants. Through the free test conducted at the beginning and the Post test at the end of the activity, measuring competence has been optimal as reflected in the practical implementation of Quality control
