Abstract

The rising demand for electricity in Manokwari, the capital of West Papua Province, Indonesia, necessitates urgent improvements to the existing 20 kV distribution system, which struggles to maintain voltage compliance with grid code standards and meet projected future loads. This study examines two operational alternatives: (1) the construction of a 150 kV transmission line from the Gas Engine Power Plant (PLTMG) substation to the Prafi Substation, and (2) the development of an express feeder from the same source. Using DigSILENT PowerFactory software, operational feasibility is assessed through voltage regulation, transformer and line loading analysis, and N-1 contingency compliance. The investigation includes power flow simulations, short-circuit fault analysis, and system stability evaluations, focusing on rotor angle, voltage, and frequency stability. Findings provide technical recommendations to enhance the reliability, resilience, and sustainability of Manokwari’s power infrastructure, supporting strategic planning and operational optimization.

Abstract

Medium carbon steel is widely used due to could conduct heat treatment to modify the microstructure and mechanical properties. Quenching is one method to modify the microstructure and mechanical properties. In the present study conducted heating samples at 850°C using an electric furnace, then held them for 60 minutes and quenched in various media (saline water, oil, and distilled water). Afterward, the quenched sample was investigatedmicrostructure, hardness, and corrosion using an optical microscope, Vickers hardness tester, and weight loss method. 5% NaCl quenching media could result in samples more uniform and martensite due to the high cooling rate.More uniforms and martensite have the beneficial highest hardness and lowest corrosion rate for around 762.4 HV and 76.04 mpy.

Abstract

This study analyzes the effect of different saltwater (NaCl) concentrations in the quenching medium on the microstructure, hardness, and corrosion rate of low-carbon steel after the hardfacing process. Hardfacing was performed using a DF2A-450-R electrode, followed by rapid cooling in distilled water containing 3.5%, 7%, and 10.5% NaCl. Microstructure was observed using an Olympus BX51M optical microscope, hardness was tested by the Vickers method, and corrosion behavior was evaluated via electrochemical Open Circuit Potential (OCP) and Linear Sweep Voltammetry (LSV). The results show that higher NaCl concentrations accelerate cooling and promote a more dominant martensitic structure. The 10.5% NaCl specimen achieved the highest hardness of 582.1 HV and exhibited a more positive corrosion potential with the lowest corrosion current. Therefore, the 10.5% NaCl quenching medium provides the optimal balance between hardness improvement and corrosion resistance, making it suitable for post-hardfacing heat treatment of low-carbon steel in demanding industrial applications.

Abstract

This study investigates the effect of oil viscosity as a quenching medium on the hardness and corrosion rate of mild steel after hardfacing. The specimens were quenched using oils of different viscosities (SAE 30, SAE 40, and SAE 50) after hardfacing treatment. Microstructural analysis using an Olympus BX51M optical microscope revealed that lower-viscosity oil produced a more dominant martensitic phase, while higher-viscosity oils resulted in greater formation of ferrite and pearlite due to slower cooling rates. The Vickers hardness test showed the highest hardness value of 460.44 VHN for SAE 30, decreasing to 415.18 VHN for SAE 50. Electrochemical testing indicated that the corrosion current density (Icorr) and corrosion rate increased with oil viscosity, from 95.2 µA/cm² and 1.114 mmpy (SAE 30) to 129.1 µA/cm² and 1.511 mmpy (SAE 50). The results demonstrate that lower-viscosity oils enhance martensitic transformation, improve hardness, and reduce corrosion rate, highlighting viscosity control as a key factor in optimizing post-hardfacing heat treatment performance.

Abstract

This study aims to determine the effect of the addition of chromium in the SMAW process to the tensile strength, hardness value and macro structure of the low carbon steel welding joint using E6013 electrodes. The research procedure begins with the process of welding, making seam, making specimens: tensile test, hardness test and macro structure. Furthermore, the process of tensile, hardness and macro structure testing is carried out. The tensile strength value of the weld joint with the addition of chrome tends to be slightly smaller than that of the weld without the addition of chrome. The maximum tensile stress and elasticity limits for welded joints with added chrome are higher than for welded joints without added chrome. The addition of chrome to the welding process has been shown to increase hardness. In the macro structure, porosity did not occur both specimens with the addition of chromium and without the addition of chromium.

Abstract

The current becomes a factor influencing the hardness value In the welding. The higher the welding current would affect the higher the hardness test results. If the current were used is low it will make it difficult to ignite the electric arc. Aims of this study to determine the effect of welding current (90, 110 and 130 A) and buffer layer on hardness, macro and microstructure layers are result from hardfacing using AWS A5.13 EFe2/AWS A.51 E7018 elektrodes. The hardfacing process uses a Shielded Arc Metal Welding (SMAW) welding machine with DC+ polarity. Hardfacing consists of three layers, 1st layer uses AWS A5.13 EFe2 electrode, 2nd layer uses AWS A.51 E7018 electrode, and 3rd layer uses AWS A5.13 EFe2 electrode. The increase in hardness will occur significantly after hardfacing on the base metal. The higher welding current is resulting the higher hardness value. The hardness of the 130 A specimen is higher than 90 A and 110 A specimen. In the 130 A specimen the hardness value was 468.1 VHN, and in the 90 A specimen the hardness value was 358.94 VHN.

Abstract

Painting is a process to make a thin layer of paint over an object. Factors to beautify the results of painting on the vehicle body are given a layer of varnish. To produce a quality varnish coating, it is necessary to pay attention to the ratio between the varnish-solvent used and the drying method used. This study aims to determine the mixture of varnish - solvent (1:0,1 and 1:0,2) with a drying temperature method of 40°C, 60°C, and 80°C on gloss, thickness, and adhesion to the motor vehicle body. The lower the oven temperature, the higher the gloss and the thicker the coating. The best adhesion at the oven temperature of 40ºC and 60ºC on all varnish-solvent compositions. The higher of the solvent mixture would result glossier and less thickness of the layer form.

Abstract

A custom spray coating refill equipment has been designed and fabrication. For this reason, it is necessary to trial the equipment that has been made. This study aims to determine the performance of custom spray coating refill equipment. For a comparison parameter, coating and thinner mixture variations were conducted to determine the adhesion and thickness of the coating layer formed. The coating used in this experiment was Nitrocellulose (NC) and Polyurethane (PU) thinner. The ratio of coating and thinner mixture used are 1:1.5, 1:2, and 1:2.5. After mixing, the mixture was put into the sprayer using custom spray paint refill equipment. The mixture of coating and thinner was sprayed onto the SPCC steel plate. To measure, the adhesion and thickness of the coating layers, a cross-cut tool (according to ASTM-D3359) and a thickness gauge (according to the ASTM-AMT15) were carried out respectively. It seems the spray paint refill equipment was functioning properly. This is due to the quality of the coating layers having good adhesion, shown by all specimens getting 5B classification (0% not peeled off). Moreover, an increase in the thinner composition is lead to a decrease in the coating thickness.

Abstract

This study investigates the effect of the increased welding layers welded by the SMAW process on distorsion, thickness, microstructure, hardness, and corrosion. The method used in this research is experimental. Low-carbon steel with a size of 150x10x10 mm was welded by the SMAW technique using an HV 450 electrode. Variations in the welding layers are single, double, and triple. The three variations of the samples were observed with a digital camera and an optical microscope. Moreover, samples were tested with a hardness tester. Corrosion testing was also carried out to determine the corrosion rate of the layers formed. The results showed that the number of SMAW welding layers affected the thickness, phase, hardness, and corrosion rate. The hardness of one layer is less than that of thicker specimens, while the corrosion rate of three layers is lower than that of less-thick samples.
