Abstract

Coconut shell waste in the community is often not utilized, so a solution is needed, one of which is by processing it into briquettes. Charcoal briquettes are solid fuels that contain carbon, have high calorific value, and can burn for a long time. These briquettes are made from organic waste, such as dry leaves, coconut shells, rice husks, and sawdust. The purpose of this study was to design a coconut shell charcoal crusher as a raw material for briquettes, with the hope of reducing coconut shell waste, increasing its economic value, and providing an alternative fuel for household needs. The process of making the tool begins with frame design, iron cutting, welding using the SMAW method, assembly, and finishing. The results of the study showed that the results of making a coconut shell charcoal crusher for briquette raw materials can function well. The distribution of the resulting size shows that the machine has a consistent ability to produce fine particle sizes, which are in accordance with the needs of briquette raw materials. The efficiency of time per kilogram of material processed tends to vary depending on the capacity used

Abstract

This study analyzes the effect of E7018 electrode current variation on SMAW welding process on AISI 1041 steel material, using penetrant test and bending test as evaluation methods. AISI 1041 steel is often used in construction industry because of its good mechanical properties and its ability to be welded with various techniques. Testing was conducted with welding current variation of 100 A, 110 A, and 120 A. The test results showed that welding current significantly affected the strength and resistance of the material to deformation. At 110 A current, the material showed an optimal combination of strength and flexibility. Higher current (120 A) tended to increase the maximum stress in Root Pass test, but decreased the strength in Capping. This finding emphasizes the importance of selecting the right welding current in determining the strength of the welded joint, in addition to considering heat distribution and changes in material microstructure.

Abstract

Shell and tube heat exchangers are essential components in the process industry, utilizing heat from exhaust gases to superheat steam in the production process. Their performance significantly determines the overall energy efficiency of the system. This study presents a case-based novelty by evaluating the actual performance of a shell and tube heat exchanger at PT. XYZ through Computational Fluid Dynamics (CFD) using Ansys Fluent 17.2. Simulations were conducted to analyze the distribution of temperature, pressure, and fluid velocity, as well as to calculate their effectiveness and LMTD. The simulation results show that the temperature of the cold fluid increases from 11.95°C to 19.35°C, while the temperature of the hot fluid decreases from 62.05°C to 49.55°C. The fluid pressure also decreases significantly, from 1717 Pa to -76.48 Pa on the tube side. The LMTD value is 40.09°C, and the heat transfer effectiveness is 24.95%. To ensure reliability, the simulation results were validated against actual operating data from PT. XYZ. This study contributes by providing a representative picture of the real operating performance of shell and tube heat exchangers, which can serve as a practical basis for improving system design and energy efficiency in the process industry.

Abstract

The welding repair process greatly affects the procedure of a welding process to be able to obtain the results of a connection that is safe and in accordance with its provisions. The strength of the welded joint must be considered and ensured that its strength is at least close to the original strength of the material used. In a welding process, errors or omissions are often made accidentally by the welder or the work environment and the selection of welding variable parameters is not appropriate so that welding defects occur. Welding defects can affect the strength of the weld joint. The purpose of this study was to determine the effect of welding repair on the mechanical properties of ASTM A36 material. The material used in conducting this research and testing is ASTM A36 steel plate. Welding was carried out on 4 specimens with the method without repair, repair 1x, repair 2x and repair 3x. Based on the test results, the number of repairs greatly affects the strength of the material connection. The highest maximum tensile strength value in 1 repair specimen is 501.90 Mpa and the lowest is in unwelded material or base metal of 467.97 Mpa. The results of the highest hardness test on the repair material 1 time of 30.83 HRC in the weld metal area and the lowest hardness value on the repair specimen 3 times in the HAZ area of 21 HRC. The results of the macro photo test on each specimen did not detect any welding defects on the inside of the welded material. the largest HAZ width in the 3 times repair material is 21.5 mm and the smallest HAZ width in the specimen without repair is 18 mm

Abstract

Copper is a commonly used material for heat pipe fabrication using the welding process. However, welding copper to copper presents significant challenges due to its inherent material properties. Its exceptionally high thermal conductivity facilitates rapid heat dispersion, complicating the maintenance of a stable melting zone. Furthermore, copper is prone to oxidation, which generates brittle oxides that can adversely affect weld quality. This research paper examines the relationship between TIG welding parameters—specifically current, voltage, shielding gas flow rate, and filler rods—and the mechanical properties of the resulting heat pipe material. The study involves varying the welding current at levels of 120 A, 135 A, and 150 A, along with different types of filler rods. The results indicate that both the selection of welding current and the type of filler rod significantly influence the tensile strength of copper welded joints. Notably, the use of higher currents in ERCuSi-A welding tends to decrease hardness in the HeatAffected Zone (HAZ), while producing more complex variations in hardness within the Weld Metal (WM), dependent on the interplay between heat and the chemical composition of the filler rod. Additionally, nickel in the ERCuNi filler rod contributes to an increase in weld hardness.
