Abstract

The performance of a power plant unit is strongly influenced by various aspects, one of which is very determined by how the combustion process occurs in the combustion chamber, because it can affect the efficiency of the power plant itself, especially in the efficiency aspects of the boiler combustion process. To find out the efficient operation of the boiler, the operator as the holder of the power plant must understand what the combustion process is like in it. Good combustion will always require the right combination of fuel and air (oxygen). From the results of the research that has been done, it can be seen that if the actual amount of air flow needed for the combustion process is closer to the ideal air flow value it will indirectly increase the combustion efficiency value of the boiler.

Abstract

The scarcity of LPG gas that often occurs in Indonesia often makes Indonesian citizens uneasy. This scarcity led many researchers to conduct research that could reduce the dependence of Indonesian citizens with LPG gas. In this study, researchers conducted tests related to the use of premium steam as fuel. This test is carried out by varying the air supply, where this supply has been determined at 2 km/cm2 , 3 km/cm2 and 4 km/cm2 , in addition to the air supply this test also performs fire temperature measurements using thermocouples and data logers, where the location of the thermocouple has been located at points 1 cm, 3cm and 5 cm from the mouth of the nozzle. Based on the test results, the shape of the flame from variations in the air supply obtained the best and stable results were in the 3 km/cm2 air supply, while the other for the 2 km/cm2 air supply was found to be unstable fire and for which the 4 km/cm2 fire air supply looked large and unstable. Whereas for the highest temperature of the three placement points the thermocouple is located at the top point with a distance of 5 cm from the mouth of the fire with an average temperature of around 900oC and the lowest temperature is at 1 cm from the nozzle mouth, where the temperature is at 400oC to 550oC, in addition The temperature stability is in the air supply of 3 km/cm2

Abstract

Utilization of waste rice husk, especially in South Kalimantan, is not very efficient. Therefore, it needs more maximal utilization, for example it is used to manufacture alternative fuels in the form of charcoal briquettes. The effort to maximizing utilize waste rice husk as charcoal briquettes, we need to know the combustion characteristics. The study, we used a variation of the ratio between siam rice husk charcoal in the peat region areas and pandak is located in the tidal areas with adhesives of 5%, 10% and 15% respectively. Characteristics of testing follows SNI 01-6235-2000. Based on the results of the study, it is known that the charcoal waste of rice husk waste with a percentage of 5% adhesive has a good value compared to the addition of other adhesives, where siam rice husk has a water content of 4.9% and pandak has a higher moisture content of 5.0%, whereas for husk heating values Pandak rice is larger with a value of 5063.6 cal / gram, compared to siam rice husk with a value of 4894.5 cal / gram.

Abstract

Partamax and partalate fuel are used as vehicle fuel in parts of the world, especially in Indonesia. Partamax and partalate have their own characteristics and if they are mixed, they will change the physicochemical properties of the pure fuel and affect the combustion behavior. In this study, an experiment was conducted on the combustion of partamax vapor, partalate and a mixture of partamax and partalate by varying the air supply by 1 liter/minute, 2 liters/minute and 3 liters/minute. The results of the combustion of fuel vapors were observed in the form of temperature by measuring using a thermocouple placed in two places with a height of 20 mm and 40 mm from the nozzle mouth and observing the flame using a camera. The results obtained from the observations are the flow of fire produced in the form of a laminar flame of all fuels, The highest flame temperature is owned by partamax fuel with an air supply of 3 liters/minute of 1047 oC on a thermocouple at an altitude of 20 mm and 1027 oC at an altitude of 40 mm, while the lowest temperature is owned by partalate fuel. This is because the octane value of partamax is higher. As the octane value increases, the flame temperature increases, but the flame height decreases. In addition, when the air supply is 3 liters/minute, a lift off phenomenon occurs in the partamax fuel and partamax-partalate mixture. This is because the octane value of partamax is higher. As the octane value increases, the flame temperature increases, but the flame height decreases. In addition, when the air supply is 3 liters/minute, a lift off phenomenon occurs in the partamax fuel and partamax-partalate mixture. This is because the octane value of partamax is higher. As the octane value increases, the flame temperature increases, but the flame height decreases. In addition, when the air supply is 3 liters/minute, a lift off phenomenon occurs in the partamax fuel and partamax-partalate mixture.

Abstract

Penelitian ini bertujuan untuk mengetahui penggunaan bahan bakar yang dikonsumsi pada motor bensin 4 tak dengan merancang dan menerapkan sistem aerator untuk menguapkan bahan bakar. Metode yang dipakai pada penelitian ini adalah dengan metode pengujian (experimental method). Yaitu dengan cara memanfaatkan  aerator  yang di implementasikan pada sistem bahan bakar sepeda motor 4 tak untuk mempercepat terjadinya proses penguapan pada bahan bakar minyak. Variabel yang digunakan adalah jenis bahan bakar pertalite dan pertamax, yang diuji dengan menggunakan aerator dan tanpa aerator pada putaran mesin sekitar 1200 rpm tanpa pembebanan selama 3 menit. Hasil pengujian menunjukkan bahwa bahan bakar yang terpakai dengan menggunakan aerator untuk penguapan dapat mengurangi konsumsi bahan bakar. Pertalite menggunakan aerator mengalami penurunan sebesar 2,34 ml/min atau 50% sedangkan bahan bakar pertamax mengalami penurunan sebesar 1,44 ml/min atau 44%. The aim of this research is to determine the fuel consumption of internal combustion engines by designing and implementing an aerator to enhance fuel evaporation. The method employed in this study is experimental, using an aerator integrated into the fuel system of a 4-stroke motorcycle engine to accelerate the fuel evaporation process. The variables used are Pertalite and Pertamax fuels, which were tested both with and without the aerator at an engine speed of approximately 1200 rpm without any load for 3 minutes. The test results indicate that using an aerator for evaporation can reduce fuel consumption. Pertalite fuel with an aerator experienced a 2,34 ml/min 50% reduction, while Pertamax fuel with an aerator experienced a 1,44 ml/min 44% reduction.

Abstract

Dowel pin merupakan suatu komponen yang digunakan untuk menahan bagian- bagian mesin dan menghubungkan komponen mesin dengan cepat pada posisi yang akurat. Pada melakukan observasi di PT.Petrosea Tbk, peneliti mengamati cara pelepasan komponen dowel pin yaitu dengan menggunakan vise grip dan perlakuan khusus dengan cara pengelasan. Metode pelepasan tersebut menimbulkan bahaya pada mekanik, yaitu mekanik dapat terpental pada saat pelepasan dangan vise grip dan bahaya dari pengelasan jika proses pelepasan dilakukan pada suction fabrikasi. Metode penelitian ini menggunakan field research dengan observasi, teknik kuisoner, wawancara yang dilakukan di PT.Petrosea Tbk. Hasil perhitungan analisa special tool yang diberikan beban 100 N dapat direkduksi dengan gaya yang dihasilkan alat didapatkan hasil yaitu aman digunakan karena hasil yang didapatkan lebih dari beban yang dibutuhkan dan direncanakan. Hasil penelitian safety yaitu sebesar 58% untuk mengurangi potensi bahaya dari metode sebelumnya dan analisa manpower sebesar 50% untuk mengurangi jumlah manpower dari proses pekerjaan sebelumnya.
