Abstract

A common issue encountered with main heat exchanger equipment is improper operation, which can lead to the development of cracks in the stainless-steel pipes. The welding process alters the metal microstructure in the heat-affected zone, thereby affecting the mechanical properties of the welded joint. To mitigate this issue, TIG welding with argon shielding gas is employed. This method helps prevent oxidation and ensures the formation of a stable welding arc in 304 stainless steel, which is renowned for its excellent mechanical properties and corrosion resistance. The objective of this study is to evaluate the impact of variations in shielding gas flow on the mechanical properties of 304 stainless steel plates during the TIG welding process. The aim is to determine the optimal settings for producing robust and long-lasting welded joints. To assess the hardness of the welded joints, we employed a Brinell-type Hardness Tester FB-3000LC machine. A Brinell steel ball indenter measuring 5 mm on the HBW scale and applying a load of 125 Kgf was utilized. At a protective gas flow rate of 8 L/min, the average tensile stress was 44.72 N/mm², strain was 0.177, modulus of elasticity was 2518 MPa, and hardness was 99.712 HBW. Increasing the gas flow rate to 13 L/min resulted in an average tensile stress of 47.50 N/mm², strain of 0.189, elastic modulus of 2525 MPa, and hardness of 105.522 HBW. Further increasing the gas flow rate to 18 L/min led to an average tensile stress of 49.69 N/mm², strain of 0.192, modulus of elasticity of 2597 MPa, and hardness of 106.704 HBW. Based on the research findings, it was observed that the weld area exhibited an increase in hardness values due to the heat generated during the welding process. The use of protective gas flow during welding is deemed effective in producing well-formed welded joints, as it prevents fractures from occurring within the weld area during the tensile test process. The choice of protective gas is determined by the dimensions of the material plate.

Abstract

This study was conducted to determine the effect of spindle speed on the wear rate of CNMG 120404 carbide cutting tools using a dry machining process without coolant. The specimens used were AISI 1045 steel shafts, The cutting tool used was a CNMG 120404 carbide with conditions assumed to be the same in each experiment. The machine used was a Gedee Weiler LZ-330 G lathe with fixed parameters of 0.2 mm/revolution feed and 0.4 mm cutting depth, as well as spindle speed variations of 450 rpm and 660 rpm. The cutting time was carried out in stages starting from 5, 10, 15, 20, to 25 seconds. In this study, the parameters observed included tool wear and the surface roughness of the turning results on the AISI 1045 specimen. Tool wear was measured using visual macro documentation, while surface roughness was tested with a surface roughness tester. The results showed that the lowest wear value occurred at 450 rpm with a cutting time of 5 seconds, amounting to 0.012 mm, while the highest wear was achieved at 660 rpm with a cutting time of 25 seconds, amounting to 0.036 mm. In terms of surface quality, the lowest roughness value was obtained at 450 rpm with a cutting time of 5 seconds, amounting to 2.43 µm, while the highest roughness occurred at 660 rpm with a cutting time of 25 seconds, amounting to 4.56 µm. This data shows that the higher the speed and the longer the cutting time, the greater the tool wear and the lower the surface quality due to friction and increased temperature in the cutting zone. Wear on carbide tools is more influenced by friction between the tool and the workpiece and the duration of cutting. The speed factor is not as dominant as the effects of friction and cutting duration.

Abstract

Utilization of coffee residues such as pulp and parchment into activated carbon provides an alternative approach to electrodes in supercapacitors. The hard template method is used because of its ability to produce a more regular pore structure and higher surface area, which is very important for supercapacitor applications. This research aims to study the effect of template and activation temperature on the characteristics of coffee pulp and parchment using the hard template method. The synthesis process involves carbonization, templating with silica, and activation under nitrogen atmosphere at different temperatures. The resulting materials were characterized to evaluate their structural, surface, and electrochemical properties. The results obtained that higher activation temperature enhances surface area and electrochemical performance, indicating the potential of coffee-based activated carbon as an electrode material for supercapacitors

Abstract

Coffee is a mainstay commodity in Bener Meriah Regency, Aceh. Coffee beans contain chemicals such as caffeine, chlorogenic acid, trigonelin, carbohydrates, fats, amino acids, organic acids, minerals and volatile aromas that can produce aromatherapy effects. The use of synthetic air freshener has a negative impact on health because the volatile organic compounds released are classified as toxic compounds and carcinogens. Aromatherapy diffusers are a good choice to avoid these risks, apart from being a relaxation, it can also improve air quality, which in turn acts as a COVID-19 preventive effort. Through this Community Service program, the Malikussaleh University PKM teams helps coffee farmer partners to develop an aromatherapy diffuser product from sorted coffee bean waste or rejected/pixel coffee, namely coffee with broken conditions, holes, seeds that are too young and too old. This program is a strategic step in the context of pioneering and building micro-enterprises in Weh Tenang Uken Village so that it can improve the economy of the community and its surroundings.

Abstract

This study evaluates the technical feasibility and reliability limits of a standalone rooftop solar power plant system for the Renewable Energy Laboratory at Universitas Malikussaleh, North Aceh. Utilizing the pvlib Python library and NASA POWER meteorological data from 2022 to 2024, a high-resolution time series simulation was conducted to model energy yield, battery dynamics, and Loss of Power Supply Probability (LPSP). The results reveal a significant seasonal reliability gap, while the system achieves optimal performance in dry months with LPSP 1%, it suffers critical power failures during the monsoon season, with LPSP peaking at 31.80% in December due to consecutive low irradiance days. Furthermore, the energy balance analysis highlights a system inefficiency where substantial energy curtailment occurs during high-irradiance periods despite severe deficits in wet months. Consequently, a pure off-grid configuration is deemed technically unfeasible for critical laboratory loads without unrealistic oversizing. The study concludes that transitioning to a PV-Hybrid topology with backup generation is essential to ensure operational continuity while complying with current non-export regulatory constraints.
