The present study features analytical and experimental results of optimizing resistance spot welding performed using a pneumatic (electrode) force system (PFS). This optimization was carried out to incorporate the galvanized steel sheet material SECC-AF (JIS G 3313) and SPCC-SD (JIS 3141) sheet plate coated with zinc with a thickness of about 2.5 microns. The zinc coating on the metal surface causes its weldability to decrease. This study aims to obtain the highest tensile shear strength test results from the combination of the specified resistance spot welding parameters. The research method used the Taguchi method using four variables and a combination of experimental tingkats. This study's experimental tingkat is two tingkats in the first parameter and three tingkats in other parameters. Taguchi optimization results show that the highest tensile shear strength test obtained is 5049.64 N. This was achieved at 22 cycles of squeeze time, 25 kA of welding current, and 0,6-second welding-time, and 12 cycles of holding-time. The S / N ratio analysis found that the welding time had the most significant effect, followed by welding current, holding time, and squeeze time. The delta S / N ratio values were 0.62, 0,41, 0.34 and 0.07, respectively.

Spark ignition in internal combustion engine was occurred from the spark of the electrode which is in the middle of the spark plug. The purpose of this study was to analyze the engine performance and exhaust emissions of a gasoline engine using standard spark plugs and multi-ground electrode spark plugs. Tests are carried out on four-stroke and four-cylinder gasoline engines without engine modification at 1500 to 4000 rpm. In addition, engine torque, brake specific fuel consumption and brake thermal efficiency and carbon monoxide (CO), carbon dioxide (CO2) and hydrocarbon (HC) emissions are measured. From the results of the study, an increase in torque and power using a four-foot electrode spark plug by 0.599% was accompanied by an increase in the consumption of specific fuels 266.78 g/kWh compared to standard spark plugs. In addition, it was found that CO and HC emissions decreased, although CO2 emissions increased compared to the use of standard spark plugs. Based on the results of the study, it can be concluded that the use of multi-ground electrode spark plugs can increase engine power and torque and reduce exhaust emissions.

During this time the process of making beberuk was still done traditionally using a mortar as a mixer, so that production is very limited, while the market demand is quite high. To increase productivity, it is necessary to design a machine that can increase the production capacity of the beberuk. The research method begins with the mixing machine design process, then continues with the assembly process and engine performance test. The design of the mixing machine is done with two approaches namely functional approach and structural approach. Test engine performance on 3 power variations namely 144, 168, and 192 watts and 3-time variations namely 30, 45, and 60 seconds. The results showed that the cylindrical mixing chamber has a diameter of 20 cm and a height of 50 cm. The mixing tube has a rectangular hopper with dimensions of 37 cm long and 9 cm wide. Engine performance test results showed the best results on 168 watts of power treatment and 30 seconds with the results of mixing not bubbly and still looks tomato chunks and is not too smooth according to the standard beberuk food.

The quality of gasoline fuel is very important; therefore scientists are trying hard to improve the quality of this fuel. One of them is treating the fuel before it enters the combustion chamber or before experiencing the combustion process. The use of permanent magnets can reduce fuel consumption, and reduce exhaust emissions. This study aims to investigate the reduction of fuel consumption of a single-cylinder four-stroke gasoline engine by using electromagnetic field. Diameter and length of the copper wire used are 0.7 mm and 80 meters. The effect of the magnetic field on the engine performance was observed at various engine speed, such as 1500, 3000, 4500 and 6000 rpm. The results showed that the electromagnetic of solenoid winding reduced the specific fuel consumption. The percentage of reduction in the specific fuel consumption is 18.93%.

Post-harvest handling of grain before being ground or stored for a long time is drying or reducing water content. To dry the grain is more effective by using a mechanical dryer. In this study, grain drying was carried out using a continuous vertical dryer by varying the grain mass to determine the effect of grain mass variation on the grain drying time. Mass variations observed were 10 kg, 20 kg, 30 kg, 40 kg, 50 kg, 60 kg, with an air temperature of 50°C and an air velocity of 7 m/s. The result showed that the more grain mass the lower the drying rate. However, the drying time was longer, and the efficiency was higher. At the 10 kg, the fastest drying time was 75 minutes. Whereas at the 60 kg, the maximum drying time was 150 minutes. The highest efficiency of 8.78, occured at a mass of 60 kg and the lowest efficiencywas 1.6% occured at a mass of 10 kg.

Phase change material (PCM) is a material that can absorb and store energy and can release it based on the principle of latent heat energy storage. Beef tallow is one of the materials that can be used as PCM but its low thermal conductivity is around 0.181 W/mK. Hence, thermal conductivity is considered an important factor in the conduction heat transfer. This further affects kinetic absorption and heat release. However it is possible to increase the values by adding another material that has a high thermal conductivity. The purpose of this study is to elevate the thermal conductivity of beef tallow by adding rice husk char. This research involves direct incorporation method, where beef tallow is thawed and mixed with the rice husk char then stirred with a rotation of 100 rpm until the mixture becomes solid. Addition of rice husk char with weight fractions of 5 and 10% and grain size of 0.045 mm. Subsequently, thermal conductivity test was performed using the TQ Heat Transfer Experiment Base Unit.The results show that with the addition of rice husk can increase the thermal conductivity of PCM beef tallow. The increase obtained in the addition of 10% rice husk char is 37 times compared to the pure sample. Based on this result it is concluded that carbon-based materials such as rice husk char can be used to increase the thermal conductivity of PCM materials.

Biomass can be used for energy production from renewable sources. Due to the social resistance to crop burning, mixtures and pellets made from or including waste materials are a good alternative. Plantation waste becomes a problem, namely reducing land which ultimately destroys the soil and the ecosystem around the land. This waste has the potential to become charcoal that supports biomass production in Indonesia with modified beehive furnaces. The carbonized rubber charcoal has a fixed carbon content of 63% with 37% of ash, volatile and water impurities. And the redemption value in this process is around 15% which has a profit margin of 200% from the purchase capital of rubber wood waste. The carbonization process with modified beehive furnaces can be a recommendation for the manufacture of charcoal from plantation waste.

Experiments to know themal conductivities of silicone rubber composite were conducted. The sillicon rubber was mixed with coconut shells charcoal powder with weight variations. The weight presentage variations were 0, 10, 20 and 30%. Increasing the weight persentage was expected to increase the thermal conductivity of the composite. The speciment size was 50 mm x 50 mm x 5 mm. The speciments were tested according to the conduction heat transfer mode. To make sure that the temperatures were steady, the experiments were performed for about 6 hours. The results indicated that increasing the weight presentage raised the composite thermalconductivities. At 0% of wight, the composite had a thermalconductivity of 0.157 W/m°C, at 10%, 20% and 30% of weight compositions; the composite had thermal conductivities of 0.461 W/m°C, 0.58 W/m°C, and 0.73 W/m°C respectively.
