Abstract

This research at UKM Himasweet Tembung evaluated snack food (chocolate) packaging that was less attractive and standard, using clear plastic without information on halal logos, composition, or trademarks. The research aims to design more attractive packaging according to consumer desires, using the TRIZ method, which focuses on previous experience and eliminates contradictions. Adequate packaging is essential to protect products, convey information, and increase appeal. A survey method with a questionnaire of 100 respondents was used to collect data. Analysis using TRIZ produces recommendations for packaging improvements. As a result, the ideal snack packaging is a yellow aluminum foil standing pouch with dimensions of 14 x 25 cm (250 gr), yellow brand writing, ziplock, product information, and a picture of the snack (brown) to represent the product.

Abstract

This research aims to calculate the amount of fuel in the multi-fuel boiler unit at PT Toba Pulp Lestari, Tbk. A boiler is a closed steam boiler, and the heat of combustion is transmitted to the water until it becomes hot steaming water or steam. In the work process, it is necessary to calculate the total fired and moisture to determine the efficient level of maturity for each unit. In this research, the author found that the energy needed to evaporate water in fuel up to 0% was Palm Caul 2303.67 kcal/kg, Palm Shell 3833.25 kcal/kg, and Bark 1513.69 kcal/kg. The energy used in the Multi Fuel Boiler requires Palm Caul 186,688.4 kg/hour, Palm sheel 97,683.6 kg/hour, and Bark 181,508.9 kg/hour.

Abstract

Voltage drop is the amount of voltage lost in a conductor. The voltage drop on electric power lines is generally directly proportional to the length of the line and the load and inversely proportional to the cross-sectional area of the conductor. The magnitude of the voltage drop is expressed either in percent or in Volts. The analysis determines the voltage drop in the power distribution from the generator to the three-phase induction motor at PT. Perkebunan Nusantara II Sawit Hulu uses 30 meters of copper conductor cable with a cross-sectional area of 400 mm2. This type of copper wire material has an absolute sending voltage value of 389 volts and a total receiving voltage value of 385. So there is a voltage drop based on the length of the conducting cable of 4 Volts, and if it is a percentage, the voltage drop value is 1.03%.

Abstract

The study of wear on tool blades when cutting metal is important because it influences work results and production costs. Increasing metal hardness demands durability and strength of the chisel bit. Long periods of use and high speeds can cause wear, damage the chisel, and affect the quality of the results and production costs. This research uses a CNC lathe with a carbide cutting edge to cut mild steel. The cutting speed varies between 170 to 190 m/min with a cutting pass of 0.3 mm/revolution, a cutting depth of 0.7 mm, and a wear criterion of 0.3 mm. Turning was carried out for 2.5 minutes, then wear was observed using an optical electron microscope. The results show abrasive wear on the side of the chisel blade (flank wear) due to friction. A cutting speed of 190 m/min took 7:25 minutes, 180 m/min took 8:09 minutes, and 170 m/min took 8:36 minutes. This research proves that cutting speed influences wear rates, with wear primarily caused by abrasive friction.

Abstract

Computational Fluid Dynamics is a method for solving engineering problems, especially in cases of fluid flow, heat transfer and various related fluid phenomena such as chemical reactions. This CFD research aims as preliminary design to determine the effect of fluid flow passing through a split cylindrical object. There are three main elements in CFD programming to solve the problem of fluid flow through a split cylindrical object, (1) Pre-processor (2) Solver and (3) Post-processor which is the procedure used in this research. The flow value on the inlet side is 0.0001 m/s or in conditions Re ≤ 5 or in laminar flow conditions. The fluid used in this research is water with a density of 1.2 kg/m3. Then the resulting grid system or meshing is 21535 nodes and 21194 elements. The conclusion of this research is that the flow vortex that occurs in a split cylindrical object is smaller when compared to a cylindrical object, but the flow vortex that occurs is still larger when compared to a square object.

Abstract

This research highlights the importance of meeting employee needs to increase work efficiency and effectiveness at PT SEN, a company operating in the oil and gas industry. Using the Quality Function Deployment (QFD) method, this research aims to translate employee desires into technical attributes that management can implement. Through surveys and data collection from 25 respondents, the service attributes desired by employees have been identified, evaluated for validity and reliability, and linked to company performance. The research results show that several attributes, such as laptops with high specifications, comfortable workspaces, and integrated work dashboards, are top priorities for PT SEN employees. Service attribute performance is evaluated through the House of Quality (HOQ) matrix, and target values are set, guiding the improvement and development of necessary facilities and infrastructure. The analysis also leads to identifying unnecessary or less essential attributes of employees. In conclusion, QFD is a practical approach to determining priorities for meeting the needs of PT SEN employees. The analysis results provide significant insight to direct management in improving the work environment and service for employees by focusing on the attributes most prioritized by employee teams.

Abstract

Liquid smoke is a natural pesticide that can be produced quickly and has a low production price. Making liquid smoke is a combustion process carried out with limited air and as little fire as possible, only embers. Then, the smoke from the combustion process with limited air is channeled into a pipe with a cooling system separate from the combustion chamber. This research used a passive cooling system, soaking the heat exchanger pipe with water. The temperature of the smoke produced is kept stable in the range of 80-90 degrees Celsius. The heat exchanger pipe in this research is designed to reduce the heat from the smoke produced by combustion without producing significant air resistance. The most essential requirement is that it can be made with available materials and has low manufacturing difficulty. In selecting a prototype, a heat exchanger system design was produced using a 1.5-inch diameter iron pipe, easily found on the market. The flow of smoke to be cooled through the heat exchanger pipe is from top to bottom, preventing the resulting liquid from being trapped in the curves of the pipe and making it easier for air and smoke that is still hot to remain at the top of the pipe naturally.

Abstract

This research focuses on developing a special LPG burner for the mCHPSE-012021 Stirling engine. The burner design was developed using CAD software and fabricated using machine tools and a welding process. Tests are carried out to verify how much the burner performance meets the desired specifications. The test results show that although the burner can reach the required high temperature, the thermal efficiency is still low, at 19.72%. This figure is far below the efficiency standard for household gas stoves, according to SNI 8660:2018. These findings highlight the urgency of improving burner design and efficiency to meet established standards, improving the mCHPSE-012021 Stirling engine's overall performance, and significantly increasing energy efficiency. These improvements are necessary to ensure optimal performance and efficiency in energy use in mCHPSE systems, underscoring the importance of developing more efficient and standards-compliant burner technology to support the use of Stirling engines in microenergy applications.
