Abstract

The characteristic of natural convection heat transfer in a thermally asymmetric cavity is influenced by temperature differences and space between the heat source and cavity wall. The heat source is any bluff body placed inside the cavity. This research used a heated elliptic tube as the heat source inside the cavity. The three tubes are of 2.5 aspect ratio (AR) in a vertically aligned arrangement. The cavity was thermally asymmetric because three sides of the cavity were insulated while the other side was exposed to convection with ambient air. The clearance ratio (CR) as the ratio between the gap from the insulated wall to the major axis of the tubes to the space of the cavity is varied 0.4 and 0.6. while the pitch ratio is constant at 3.5a. this study analyzes the characteristics of heat transfer from the surface of the elliptical tube to the surrounding air experimentally and numerically. The result reveals that the highest heat transfer coefficient 0f 0.4 CR is higher than that of 0.6 CR. The numerical solution shows the contour and streamlines of the fluid flow in all conditions as the characteristics of natural transfer thermally asymmetric cavity.

Abstract

The Electric Arc Furnace (EAF) prototype at the Morowali Metal Industry Polytechnic has the main component in the form of a transformer that generates heat actively. The increase in temperature that occurs in the transformer is caused by continuous loading. In addition, a significant and relatively high temperature rise in the transformer, can reduce the performance of the transformer. This research will design a transformer cooling system on the EAF prototype. The temperature of the transformer will be maintained at a certain temperature until there is no longer an increase in temperature due to loading. The wire-tube cooling system in the transformer uses water and transformer oil as the cooling medium. Regulating the flow rate of the water fluid in the copper pipe is expected to be able to further optimize the cooling process in the transformer. The results show that the design of the wire-tube cooling system is able to release the temperature of the transformer oil with a heat transfer rate that varies according to the flow rate of the cooling water fluid. Experiments carried out for 30 minutes resulted in a heat transfer rate of Qu 760.5 kJ/s with a water flow rate of 2.5 liters/minute, Qu 1661.2 kJ/s with a water flow rate of 5 liters/minute, Qu 2558.5 kJ/kg with a water flow rate of 5 liters/minute. the water flow rate is 7.5 liters/minute and Qu 3213.9 kJ/kg with a water flow rate of 9.20 liters/minute, this shows that the higher the water flow rate, the higher the heat transfer.

Abstract

Salah satu sistem mekanisme yang mengontrol dan mendistribusikan oli pelumas ke komponen mesin yang berputar adalah sistem pelumasan. Bagian-bagian mesin yang bergesekan satu sama lain rentan terhadap keausan, yang dapat dihindari atau dikurangi dengan pelumasan. Operasi dasar sistem pelumasan adalah menyemprotkan pelumas pada bagian-bagian mesin yang bergerak yang bersentuhan satu sama lain selama penyalaan.Mesin frais merupakan salah satu mesin yang memiliki sistem pelumasan. Pada mesin frais, sistem pelumasan berada pada meja mesin yang bisa bergerak dalam sumbu X, Y dan Z. Pelumasan meja mesin frais perlu dilakukan setiap hari saat mesin akan digunakan. Menurut standar umum mesin frais, pelumasan dilakukan dengan cara menarik tuas pompa pelumas sebanyak empat kali. Namun, karena sistem pelumasan dilakukan secara manual oleh operator, hal tersebut terkadang terlupakan oleh operator. Melihat hal tersebut, peneliti melakukan modifikasi sistem pelumasan yang bertujuan supaya bagian-bagian mesin yang mengalami contact sliding dapat beroperasi dengan otomatis. Metode penelitian ini dengan cara memodifikasi sistem pelumasan manual yang telah ada pada mesin menjadi otomatis yang dikontrol melalui arduino uno dan digerakkan oleh motor stepper. Pada saat pompa pelumas terhubung arus listrik, secara otomatis pompa akan memompa sebanyak empat kali.Motor akan berhenti berputar setelah selesai memompa. Sehingga prototype yang dibuat mampu bekerja pada mekanisme sistem pelumasan mesin frais konvensional secara otomatis menyemprotkan 10ml oli.

Abstract

Higher education has an important role in the Tri Darma, namely participating in truly educating the lives of the nation and state in society. One step is to make humans no longer objects of development but subjects of development. As a development subject, abilities and skills in mastering science and technology are certainly required. The use of welding technology has developed and is widely used and exploited in the wider community, especially in meeting industrial needs. One of the welding methods is Shielded Metal Arc Welding (SMAW), namely welding using an electric arc. The aim of this activity is to increase the welding competency of Bungku Mining Vocational School students by adding special skills in the form of SMAW welding and providing encouragement and assistance so that Bungku Mining Vocational School students are able to provide welding equipment that supports learning in the laboratory. The benefit of this activity is to provide knowledge and train skills in SMAW welding so that it can be used to develop laboratory facilities.

Abstract

The COVID-19 pandemic emerged as a global public health threat. Hence, the potential danger increased the use of health masks, resulting in increased medical waste in the environment. This incident also occurred in Morowali District, especially in the PT Indonesia Morowali Industrial Park area. The waste produced by employees was disturbing; thus, it required urgent prevention and control of a pandemic. During the pandemic, the industrial area (IMIP) needed to provide various health protocol facilities that directly/indirectly benefited employees' health. This research designed a tool to solve this problem, namely the frame design of the smart shredder machine for face mask waste. This device works automatically (IOT) to shreds, process, and sterilize mask waste. The results of this tool can be monitored through periodic applications for the mask waste sterilization system and the destroyed mask waste storage system. This tool is suitable for placing in high-mobility industrial areas, such as the IMIP industrial area, which has around 60,000 employees.

Abstract

The use of automatic sorting systems in industry plays a crucial role in saving time and reducing manual labor through automation. The main challenges are the high error rate and slow manual sorting processes. This research aims to design and develop an automatic sorting conveyor system using Arduino technology and pneumatic actuators to enhance sorting efficiency and accuracy. The proposed solution is a system capable of detecting and sorting objects based on size with very low error rates, thereby increasing productivity and reducing human error. The design and development of this system involve creating a 3D model of components such as the conveyor frame, belt, motor, pneumatic actuators, and sensors, and integrating them into a complete system. Testing was conducted with seven differently sized test objects to evaluate the system's performance in detecting and sorting objects based on size and height. Input and output voltage measurements ensure performance in line with the expected specifications. The research results demonstrate that the developed automatic sorting conveyor system effectively sorts objects with high accuracy. The system can detect and sort objects based on size with a 0% error rate, reducing the time required for the sorting process compared to manual methods. The use of pneumatic actuators and appropriate sensors ensures consistent and reliable system performance. The test results indicate that the system can be integrated into various industrial applications to enhance production efficiency. The developed automatic sorting conveyor system successfully improves the efficiency and accuracy of the sorting process in industry. It shows significant potential for reducing human error and increasing productivity, making it a practical solution for various industrial applications.
