This study aims to make a rubber-based fire seal with a diameter of 32.60 mm using a Compression Molding tool. Compression Molding itself is a set of printing tools by heating and pressing. The scheme of the basic processes consists of heating a charge (thermostat and reinforcement) to a certain temperature, in the mold cavity and then pressing it with a certain pressure.The first process begins with tool preparation and mold making, then rubber is made into a 32.60mm diameter fire seal. After everything has been prepared, then cut the rubber into small pieces to meet the volume of the seal in the mold and put the rubber into the mold. Press the mold using a Â re using the thermostat. After completion, the measurement of seal shrinkage includes the inside diameter, outside diameter, and seal thickness and then compared with the mold size, so that conclusions can be drawn. The calculation is influenced by the density of the structure after the testing process.

Wind is one of the newest energy sources that is becoming increasingly popular nowadays. The use of wind energy can be converted into electrical energy for wind turbine cells. However, there are two types of wind turbines, namely horizontal and vertical. Holistic wind turbines are usually used in one direction while vertical wind turbines are used in all directions. The shape of the blades and the number of wind turbine blades greatly influence the power produced. So the research this time is to find out the influence of the blade shape that has been varied and the number of blades with wind speeds of 2.5 m/s, 3 m/s, 3.5 m/s and 4 m/s on the resulting generator power so that the efficiency results What has been obtained can be designed to design wind turbines with varied blade shapes. Testing was carried out in a laboratory designed independently with a wind source using a fan and Dimmelr air conditioner. The results of tests that have been carried out have the highest gelnelratolr power known at 4 blades with a wind speed of 4 m/s with a power value of 0.34 watts while the smallest gelnelratolr power is known at 2 blades with a wind speed of 2.5 m/s with rated power 0.04 Watt. So that the research results from all the tests, the highest efficiency value was obtained at 4 blades with a wind speed of 2.5 m/s with a value of 24.4% and the lowest efficiency value was obtained at 2 blades with a wind speed of 3 m/s 6, 4 %.

The tie rod shaft is one of the most essential parts in the coal grinder machine at the coal mill plant to support the roller grinder axial movement. Since the tie rod shaft receives the cyclic load constantly, the inappropriate design can cause the lifetime of the shaft to be short. The broken incidents of the tie rod shaft at coal mill the coal mill plant of PT X takes effect on the Steam and Power Supply to the ammonia and Urea Plant. This Research aims to analyze the abnormality on the tie rod shaft, which is always broken on the fillet section. The Stress concentration factor, Maximum Stress, and Surface roughness on the fillet section of the shaft have an extraordinary effect on the Fatigue lifetime. With the special tool assistant, the conventional lathe machine can compete with the CNC machine Quality to make Fillet contour as well as polished treatment and precise as the tool assistant can make the constant rotational movement produced by the human hand. The result showed that the tie rod shaft with 0.33 μm surface roughness level and fillet dimension strictly at 5mm could extend the lifetime of the tie rod shaft beyond the target after installed on the plant

Welding process is the joining of two metals by heating. There are two types of welding that are often applied in the field, namely gas welding (OAW) and electric welding (SMAW). Both of them have their advantages as metal connectors. This research originated from a problem that occurred in the upper arm on the welding table which experienced bending as a result of carrying the load when holding the welding disc. Therefore, CAD/CAE design is carried out. In this case, the strength and tension that occur in the upper arm are analyzed. This research aims to reveal the value of the stress that occurs in the upper arm and the safety value. Where in the design the planned force capacity is 300 newtons using the finite element method or also known as Finite Element Analysis (FEA). And the material used is ASTM A36. The results of the simulation and also the analysis that has been carried out show that the upper arm frame structure on the welding table has a stress, deformation, and safety factor of 311.987 MPa, 2.28286 mm, and 0.663488 ul.

Empty fruit bunches of Palm Oil (EFB) are a potential source of biomass energy because they contain lignocellulose (cellulose, hemicellulose and lignin) so that they can be converted into biopellets for co-firing. The purpose of this research is to determine the raw material properties of EFB in the form of proximate, ultimate, lignin, and biopellets. Using a pelletizer, biopellets are created by adding starch as an adhesive. The raw material characteristics of EFB from proximate analysis revealed moisture content of 11.98%, ash content of 6.53%, volatile matter content of 65.15%, and fixed carbon content of 16.44%. According to the final study results, the biopellets from empty fruit bunches included 48.53% C, 6.05% H, 0.32% N, 36.8% O, and 0.08% Sulphure. The atomic ratio obtained from the final analysis results could be used to determine the calorific value that can be used for fuel; the biopellet calorific value of EFB is 4,583 kcal/kg, with Hardgrove Grindability Index (HGI) values of 78.6 and Ash Fusion Temperature (AFT) 1100oC. The lower the value of the atomic ratio contained, the higher the calorific value contained in a specific fuel.

Ceramics are non-metal material and are able to meet in daily activities. Generally, ceramic have superior high temperature strength, higher hardness, lower density and lower thermal conductivity than metal. The disadvantages of ceramics as structural materials are flaws, such as cracks, voids, and inclusions. In development of ceramics can be used in medical field for instance, implant of bone or tissue of the body. Hydroaxyapatite (HAp) is one of ceramics that is applied in medical field. In natural resources HAp is easy to find in every place in the world. The advantage of ceramics is bio- comfortable and disadvantages is poor fatigue properties, this material cannot be used in bulk form fro load bearing application such as orthopedics.
