Coffee roasting plays an important role in determining the chemical composition, aroma, and taste of coffee. There are two main types of coffee roasters, namely drum and hot air roasters. This research aims to determine the heat transfer in hot air coffee roasters. The data collected consists of roasting time, coffee bean temperature, roasting room temperature, fuel consumption and air flow speed in the cyclone system chimney and sample was carried out at medium roasting level, with three repetitions. The method used is theoretical analysis and experimental testing. The results showed that the heat transfer mechanism in hot air roasting is a conduction and convection mechanism. The amount of conduction and convection heat transfer in the coffee roasting equipment was carried out in three repetitions. It was also found that factors that influence the rate of heat transfer in hot air roasting equipment are due to conduction and convection, as well as influenced by heat transfer surface area, thermal conductivity, air flow speed from blower pressure and pressure on the gas fuel. The results of the research show that the heat transfer mechanism in hot air roasting is a conduction and convection mechanism. The amount of heat transfer in one repetition of the conduction quantity (Q) is 9222.8 W and the convection rate (Q) is 3209.4 W with an average efficiency of 34.7%, in two repetitions the conduction quantity (Q) is 9883.3 W and the convection rate (Q) is 3444.6 W with the average efficiency is 34.8%, at three repetitions the conduction (Q) is 9690.3 W and the convection rate (Q) is 1123.3 W, the average efficiency is 11.6%. Factors that influence the rate of heat transfer in hot air roasting tools are conduction and convection, heat transfer surface area, thermal conductivity, air flow speed due to blower pressure and pressure on LPG gas fuel. </p>2023-11-28T00:00:00+07:00Copyright (c) 2023 VANOS Journal of Mechanical Engineering Educationhttps://jurnal.untirta.ac.id/index.php/vanos/article/view/21717The Effect of Cryogenic Treatment Temperature on the Mechanical Properties and Microstructure of 440C Martensitic Stainless Steel2024-01-09T16:12:25+07:00Indah Uswatun Hasanahindah.uswatun.h@gmail.comA. Ali Alhamidialhamidi@untirta.ac.idRachmat Suryanarachmatsuryana@gmail.com<p>The use of stainless steel worldwide is increasing due to its favorable mechanical properties, such as high hardness, corrosion resistance, and wear. One of the martensitic stainless steels is SS 440C. One of the main effects of increasing the significant carbon content is lowering the final martensitic temperature (MF) of the steel. If this temperature is below room temperature, the quenching process leaves austenite in the microstructure. This is commonly known as retained austenite (RA). In general, minimizing the number of RAs is recommended, as they can cause excessive wear. Therefore, the aim this research is for reduce the retained austenite content in SS 440C steel with a cryogenic treatment process. The cryogenic treatment was carried out for 50 minutes at temperatures of -80, -110, and -140°C and compared with non-cryogenic treatment to determine the residual austenite, hardness, and wear resistance. The highest hardness and wear resistance values were obtained from cryogenic treatment at -140°C at 58 HRC and 2.2 x 10-3 mm<sup>3</sup>/m. The metallographic results produce a martensite microstructure, residual austenite, and carbide phases. XRD analysis on cryogenic treatment samples at -140°C yielded structures of iron bcc, iron fcc, M7C3, and M23C6 compounds.</p>2023-11-28T00:00:00+07:00Copyright (c) 2023 VANOS Journal of Mechanical Engineering Educationhttps://jurnal.untirta.ac.id/index.php/vanos/article/view/21269Preventive Maintenances of Waste Crushing Equipment at Subang State Polytechnic2024-01-09T16:12:25+07:00Indra Indraindra@gmail.comAdhan Efendiadhan.efendi@gmail.comYohanes Sinung NugrohoSinung@polsub.ac.id<p>The research in this final project aims to determine the preventive maintenance schedule for the plastic waste smelter and to determine the application of preventive maintenance to the plastic waste smelter. The maintenance process for this tool uses preventive maintenance with inspection, small repair, medium repair and overhaul (ISMO) methods. The implementation method of waste smelter into plastic involves data collection through direct observations of the smelter area, component identification, maintenance schedule planning, expert validation, and routine preventive maintenance execution. The research findings indicate that the systematic and scheduled application of maintenance effectively preserves the optimal performance of the smelter machine. These measures not only enhance operational efficiency but also reduce the risk of damages and potential downtime that could disrupt the production process, contributing to the sustainability and quality of plastic waste processing.</p>2023-11-28T00:00:00+07:00Copyright (c) 2023 VANOS Journal of Mechanical Engineering Educationhttps://jurnal.untirta.ac.id/index.php/vanos/article/view/21574Leadership as a Factor in Maintaining Quality Assurance in Technology and Vocational Education and Training: A Systematic Literature Review2024-01-09T16:12:25+07:00Quienera Joshuaquieneranyeon@yahoo.comSupriyanto Supriyantosupriyanto1497@upi.eduTutin Aryantitutin@upi.eduMervyn Wong Hsin Jyiwhjmervyn@unimas.myEmmanuel Obobi Tettehfioetettehfio@htu.edu.gh<p>This article focuses on the concept of leadership, which involves managing organizations or groups of individuals, particularly in the context of TVET institutions and sectors.

Work readiness is prepared with the demands of the industrial world in mind. The objective of this study is to create and evaluate industry-based integrated learning models for EVL+i, or electric vehicle auxiliary, subjects. The research and development (R&D) design used was Richey and Klein's design. This research involved 34 students, 6 teachers from the automotive engineering department of SMK Muhammadiyah 2 Tempel, and 4 professionals from the automotive industry. Practical performance tests and interviews were used as data collection methods. Based on the research results, it can be said that the EVL+i model was successfully developed and implemented in three stages of research. The EVL+i model can improve 6 aspects of competence of automotive vocational students, namely aspects of integrity competence, cooperation, discipline, work area knowledge, work completeness and time efficiency. The six aspects of competence have increased from the category of less good to very good with an average score of 1.82 in the limited trial and 3.72 in the extended trial.</p>2023-11-28T00:00:00+07:00Copyright (c) 2023 VANOS Journal of Mechanical Engineering Educationhttps://jurnal.untirta.ac.id/index.php/vanos/article/view/22321Wing Simulation Using Naca 2412 and 2415 Airfoils with Variations in Angle of Attack for Lift and Drag2024-01-09T16:12:25+07:00Medyawanti Panemedyawanti.pane@uki.ac.id<p>The geometry of an airfoil plays a critical role in shaping an aircraft's performance, especially during maneuvering. This study emphasizes the necessity of conducting a comprehensive geometric analysis to better understand the effects of airfoil design. In pursuit of optimizing airfoil performance, we conducted extensive tests on NACA 2412 and 2415 series airfoil geometries using the ANSYS Fluent software. The tests employed Aluminum Alloy 1067 material and a wind speed of 300 m/s, encompassing a range of angle of attack variations from 0 to 180 degrees. The simulation results provided valuable insights into the velocity and pressure distributions surrounding the airfoil. Of particular interest, at an angle of 15 degrees, the NACA 2412 airfoil exhibited a maximum drag force of 69.670 N and a maximum lift force of 550.300 N. The corresponding drag and lift coefficients were 0,1516378 N and 1,1977364 N. For the NACA 2415 airfoil, the maximum drag and lift forces were 71.470 N and 564.500 N, respectively, with corresponding drag and lift coefficients of 0,1541963 N and 1,2179072 N.</p>2023-11-28T00:00:00+07:00Copyright (c) 2023 VANOS Journal of Mechanical Engineering Educationhttps://jurnal.untirta.ac.id/index.php/vanos/article/view/22799Development Solar Cell Trainer (SCT) as Learning Media on Renewable Energy2024-01-09T16:12:25+07:00Sukardi Sukardisukardioto@fkip.upr.ac.idAgung Samudraagungsamudra@fkip.upr.ac.idAhmad Eko Suryantoahmadeko.s@fkip.upr.ac.idSyarpin Syarpinsyarpin@chem.upr.ac.idStarting from the limitations of learning media on renewable energy material, the idea of developing a Solar Cell Trainer (SCT) was sparked.
