Abstract

This article is the result of implementing the CSR program of PT PLN Magelang Regency branch to help solve problems in the Rahayu Manunggal Women Farmers Group (KWT). High production costs and low profits are obstacles faced by KWT Rahayu Manunggal. This problem is caused by the production process of making brown sugar which uses quite a lot of energy, including the drying process of brown sugar. Applying an energy-efficient oven at KWT Rahayu Manunggal can help overcome this problem. The concept of the oven machine is designed by utilizing the heat/energy stored in the exhaust gas produced by the sap cooking furnace. The results obtained from this system can increase profits and reduce production costs, as well as improve the cleanliness of brown sugar processing.

Abstract

This article presents a research review of automotive vocational lecturers in Indonesia obtained from google scholar during 2016-2018. We found more than 500 articles on google scholar produced by 277 lecturers from automotive vocational programs. However, through data filtering, there are only 208 publications related to automotive, including the development of learning media in VHE. Looking at the world automotive research trend (which leads to major issues regarding battery systems, downsizing and turbocharging, and advanced combustion modes), and with concerns about the availability of fossil energy, major and fundamental reforms are needed for research activities in automotive vocational lecturers in Indonesia, both in terms of topic and depth of research material. As a recommendation, stakeholders in automotive vocational programs in universities should immediately form a research roadmap together and form a national automotive research consortium in order to contribute in realizing environmentally friendly vehicle technology and a sustainable national transportation system.

Abstract

The bi-fuel system vehicle (gasoline/LPG) has been developed for a long time because it has the ability to switch fuels, both built as an original equipment manufacturer (OEM) or as a modified vehicle. However, on vehicles with planetary automatic transmissions, additional control systems are needed to produce optimal performance, both on gasoline and LPG operations, especially on uphill roads. Old vehicles with planetary automatic transmissions are not equipped with road slope angle sensors, so on uphill roads and the driver has not mastered road conditions, the engine tends to stop suddenly. Therefore, this study aims to develop a fuel control system (LPG operation) on a planetary automatic transmission to control gear shifts based on the level of the road slope. A simulation with MATLAB Simulink we used to create a control system, with objective function and constraint defined. As a result, the control system can recognize the level of the road slope to control the speed gear shift. This control system is promising and reliable to be implemented in real conditions.

Abstract

Gedangan village, a dairy farming center, has many biogas reactors that are used for cooking and lighting petromax lamps. Previous community service activities resulted in the construction of three Biogas Power Plants (PLT-Biogas) capable of producing 15 kW of power but which were not fully utilized. Participatory Rural Appraisal (PRA) is the approach method used to actively involve the community in the program. To optimize the PLT-Biogas, the service team rearranges the equipment and replaces the UPS with an inverter and battery charger before constructing a street lighting electricity network that can be used by the entire community. The next step is to provide operational and maintenance training for the long-term use of PLT-Biogas. As a result, the initial stage of electrical energy is currently used for street lighting in two hamlets, as well as freezers and water pumps, with a potential savings of 2,775.6 kWh per year. By converting biogas energy to electricity, this community service activity can help to kickstart the realization of an energy self-sufficient village.

Abstract

The emergence of Corona Virus Disease 19 (Covid-19) required a new method to control its spread. During this time, controlling COVID-19 was carried out by implementation of a sterilization chamber using a liquid-based disinfectant. However, the use of liquid-based disinfectants has been evaluated to be less effective because it allows disrupting the respiratory tract. Therefore, this work presents a negative pressure sterilization chamber using Ozone and UV-C lamp. Ozone has been recommended by the Indonesian Institute of Sciences (LIPI) as a substitute for liquid-based disinfectants. In addition, to maximize performance, the chambers are added with UV-C lamps. The negative pressure sterilization chamber with Ozone and ultraviolet lamps was successfully created with the main parts of the cubicle chamber, an Ozone generator, at least one ultraviolet lamp, exhaust fan, switch, and a timer. The negative pressure sterilization chamber with Ozone and ultraviolet lamps according to this work, where the Ozone supply from the Ozone generator is made automatically to the door opening and closing. The duration of the Ozone supply was regulated by a timer. Then, the ultraviolet lamp can be activated together with Ozone or independently. With the implementation of this sterilization chamber, the spread of the Covid-19 virus is expected to be suppressed in a safer way than using liquid-based disinfectants.

Abstract

In the past decade, the general method for measuring the performance of research and scientific publications in a Study Program at a Higher Education is by the Rough Value (Nilai Kasar, NK) calculated per three years. This value is derived from the accreditation instrument. In fact, the calculation of the performance of research and scientific publications with NK cannot represent an annual performance. Therefore, this paper presents a new method for calculating research and scientific publications performance with an index (IP-PS and IPub-PS), which is calculated annually. An example of quality measurement practice in the Automotive Diploma Program of Universitas Muhammadiyah Magelang. As a result, calculations with IP-PS and IPub-PS are more likely to present real conditions per year than using NK.

Abstract

Liquified petroleum gas (LPG) storage tanks are essential components for storing and distributing fuels. However, system failures due to inspection flaws increase the risk of leaks, fires, and explosions. Therefore, this study discussed the development of a safety system application applied to LPG storage tanks based on a risk-based leak (RBL) analysis. Data associated with risk factor values were obtained from an LPG storage tank in a gas distributor company. The risk of failure was calculated by analyzing the probability of failure (PoF) and the consequence of failure (CoF). The results showed that the level of risk observed was medium-high with a PoF in category 1 at a total damage factor value of 1. Furthermore, the CoF in category E was positioned with a consequence analysis value of 2381.29 m2 with an LPG storage tank life span of 33.5 years and an external inspection interval of five years.

Abstract

Magelang Regency has several superior products for MSMEs, one of which is the production of processed boilers / slondok. The partner in the creativity program for students in the application of science and technology (PKM-PI) is UMKM Slondok Pak Narto with the address Druju Tegal Hamlet, Plosogede Village, Ngluwar District, Magelang Regency, Central Java. The problem faced by partners is that it requires a large area to dry product raw materials, besides that during the rainy season the drying process cannot be carried out so slondok production will stop. The purpose of this PKM-PI is to apply appropriate technology in the form of an oven that utilizes heat from the exhaust waste gas from combustion in the boiler steamer furnace and slondok fryer. This heating oven is able to help dry the raw materials of the product up to 45%.
