Abstract

Pengangguran di Indonesia secara umum masih cukup tinggi sekitar 7 juta orang sesuai data BPS pada Agustus 2018. Sebenarnya bukan hanya tugas pemerintah yang harus menurunkan jumlah pengangguran tersebut, tetapi juga peran Perguruan Tinggi dalam tugas Tridharmanya, yaitu Pengabdian kepada Masyarakat. Selain daripada itu pekerja konstruksi Indonesia yang jumlahnya 8,3 juta masih mempunyai kualitas rendah. Hanya sekitar 7,4% yang mempunyai sertifikat atau sekitar 616.000 orang dan hampir 2/3 yang bersertifikat tersebut masih dalam tingkatan “TERAMPIL” dan sisanya bersertifikat tingkat “AHLI”. Dari alasan itulah maka Laboratorium Proses Manufaktur dengan peralatan praktikum las listrik yang tersedia akan ikut berpartisipasi aktif dalam mengurangi angka pengangguran dan menciptakan keterampilan dalam bidang MEKANIKAL dengan subbidang Tukang Las. Pelatihan keterampilan las listrik ini bertujuan selain memberikan keterampilan bagi peserta baru yang ingin menjadi tukang las. Dampak yang diharapkan untuk Pelatihan keterampilan Las listrik ini adalah terciptanya tukang las baru yang siap bekerja baik di bengkel-bengkel las dan tukang las yang dapat mengisi lowongan kerja sebagai tukang las. Internet memasarkan menjadi Tukang Las lepas “Freelance” bermodal kecil yang dapat dipanggil ke Rumah. Untuk itu pada pelatihan ini diberikan suatu proyek sederhana untuk membuat produk seperti rak sepatu, gantungan handuk dan sejenisnya.

Abstract

Increasing demand for oil as a fuel and declining production in refineries led to a nationwide fuel oil shortage. Hence compelling academics to develop answers, renewable energy is one of the proposed options. Compression ignition machines utilize renewable fuels such as biodiesel, crude palm oil (CPO), and hydrogen gas. Using biodiesel without modifying the engine can result in decreased thermal efficiency and increased smoke emissions. The addition of modest volumes of hydrogen gas can enhance the performance of diesel engines. The purpose of this investigation is to investigate the performance and emissions of diesel dual-fuel engines. In this investigation, a one-cylinder diesel engine with direct injection was operated at a constant 2000rpm with a 50 percent load. Flow variations of 2.5, 5, 7.5, and 10 liters per minute of hydrogen. Compared to biodiesel fuel, the results of this study indicate that a 10LPM hydrogen flow can boost thermal efficiency by 29.85% and a 7.5LPM hydrogen flow can increase power by 0.78 %. Moreover, the use of hydrogen gas reduces exhaust pollutants. Reduced HC, CO, and CO2 emissions by 26ppm, 0.01%, and 2.60%, respectively, for a 10LPM hydrogen flow.

Abstract

A diesel dual-fuel engine uses two fuels designed to reduce the consumption of fossil fuels. Generally, the specific fuel consumption of diesel dual-fuel engines has increased.  However, in   combination with alternative fuels, namely compressed natural gas injected through air intake, the use of diesel fuel can be reduced. However, using two fuels in a diesel dual-fuel engine increases the equivalent ratio; therefore, the air and fuel mixture becomes richer because the air entering the cylinder during the intake stroke is partially replaced by compressed natural gas. This results in incomplete combustion and increases exhaust emissions, particularly hydrocarbon (HC) and carbon monoxide (CO) emissions. This study aims to improve the combustion process in dual-fuel diesel engines by improving the air-fuel ratio; thus, it can approach the stoichiometric mixture by adding combustion air forcibly to produce complete combustion to reduce CO and HC emissions. An experimental approach using a single-cylinder diesel engine modified into a diesel dual-fuel engine powered by crude palm oil biodiesel and compressed natural gas was adopted. The combustion air was forcibly added to the cylinder using an electric supercharger at different air mass flow rates ranging from 0.007074 to 0.007836 kg/s and different engine loads (1000 to 4000 watts). The results indicated that adding more air to the cylinder could produce complete combustion, reducing the emission levels produced by a diesel dual-fuel engine. An air mass flow rate of 0.007836 kg/s can reduce CO, HC, and particulate matter emissions by averages of 60.55%, 49.63%, and 86.87%, respectively, from the standard diesel dual-fuel engine. Increasing in the amount of oxygen concentration improves the quality of the air-fuel ratio, which results in improved combustion and thereby reducing emissions.

Abstract

The study investigates the effectiveness of a Battery Thermal Management System (BTMS) using a hybrid configuration of paraffin oil and fan cooling. The research employs a comparative test method to evaluate the BTMS's potential in managing the thermal conditions of lithium-ion batteries, commonly used in electric vehicles. The study is conducted under three configurations: hybrid cooling with paraffin oil and fan, passive cooling with paraffin oil, and no cooling system. The ambient and liquid temperatures are measured, alongside battery voltage changes over a 60-minute period. The results indicate that the hybrid cooling system effectively maintains lower battery temperatures compared to passive and no cooling systems. Specifically, the hybrid system achieves an average ambient temperature of 33.344°C and a paraffin oil temperature of 32.982°C, demonstrating its superior cooling capability. The study concludes that the hybrid BTMS can significantly enhance battery performance and longevity by maintaining optimal temperature conditions, thus offering a viable solution for improving the efficiency and safety of electric vehicle batteries. This research has implications for the development of more effective thermal management systems in electric vehicles, potentially leading to increased adoption and improved sustainability in the automotive industry.

Abstract

Batteries, crucial for hybrid and electric vehicles, inevitably experience capacity loss over time due to regular usage, known as battery aging. The degradation is influenced by factors like the C-rate, depth of discharge (DOD), and temperature variations. This study delves into a hybrid series-configured vehicle that integrates both a battery and an engine-generator as primary energy sources. The primary objective revolves around determining an optimal energy management system (EMS) that mitigates battery aging effects. Testing was conducted across varying speeds: 17 km/hour, 30 km/hour, and 50 km/hour, involving two operational modes—full electric and hybrid. The engine-generator activation was contingent upon the battery's state of charge (SOC) set at 40% and 60%, operating consistently at 7000RPM and 7500 RPM. Data collected from these experiments facilitated the assessment of battery aging, simulated through MATLAB Simulink software. The findings highlighted that the most favorable battery aging occurred at 50 km/hour, when the engine-generator was engaged at 60% SOC and operated at an engine speed of 7500 RPM. Notably, the hybrid mode showcased superior battery longevity, particularly at higher speeds.

Abstract

The energy used in the hybrid vehicle needs to be regulated to gain further mileage and lower fuel consumption. It is achieved by selecting the correct levels of hybrid energy management system (EMS) parameters (i.e., vehicle speed, engine RPM, and activation State of Charge (SOC) of battery). This study focused on the modeling and optimization of Sepuluh Nopember Institute of Technology (ITS)’s series plug-in hybrid electric vehicle (PHEV) car mileage and fuel consumption by comparing the backpropagation neural network (BPNN) method – genetic algorithm (GA) and BPNN – particle swarm optimization (PSO). The BPNN was used to model the character of ITS’s series PHEV EMS and predict mileage and fuel consumption. The BPNN’s model obtained the best EMS parameters, most extended mileage, and minimum fuel consumption. The result of the validation experiment showed that both the integration of BPNN - GA and BPNN - PSO were able to predict and optimize the multi-objective characteristic with the same results.
