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.

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%.

In 2022, the World Liquified Petroleum Gas Association (WLPGA) reported that there are more than 28.3 million LPG-fueled vehicles used throughout the world with an increasing trend in the last 20 years. The growth of LPG-fueled vehicles will require more mechanics from vocational school graduates who master environmentally friendly technology. Considering the availability of resources, Muhammadiyah Vocational High School 1 Bandongan Magelang (SMK MUTU Bandongan) has the potential to complement the competencies of graduates with mastery and skills in servicing modern and environmentally friendly vehicles, as one of their uniqueness from others. Therefore, we develop and implement environmentally friendly automotive technology learning media, especially LPG-fueled vehicles at SMK MUTU Bandongan. This is an implementation of research on LPG-fueled vehicles over the last 10 years. Activities are carried out through (1) rebuilding and reconditioning the engine which will be modified into a bi-fuel engine; (2) procurement and installation of converter kits; and (3) increasing teacher competency.

Nowadays, electric cars use Al 5052 in the cooling pad of the battery coolant system. Corrosion behavior study of Al 5052 by coolant is essential in the automotive industry. Ethylene glycol is the main compound of the battery coolant system that can inhibit the corrosion process of aluminum alloys. The corrosion inhibition performance of ethylene glycol (EG) for Al 5052 surface in 3.5% NaCl solution has been studied using electrochemical measurements such as potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) in various concentrations of EG up to 50% and a temperature range from 30oC to 60oC. Based on results, EG can inhibit the corrosion process of Al 5052. The corrosion rate (CR) of coolant containing EG decreases with increasing that concentration in various temperatures, and the CR of the coolant rises with the increased temperatures. The inhibition efficiency of coolant boosts with the increase in EG concentration in each operational temperature and the highest up to 75% at 60oC with 50% of EG concentration.

The Sustainable Development Goals (SDGs), established by the United Nations in 2015, are a comprehensive global framework that addresses social, economic, and environmental challenges through sustainable development. This study examines the role of universities, specifically focusing on the Department of Mechanical Engineering at Universitas Muhammadiyah Magelang (UNIMMA), in contributing to the SDGs. The study utilized data from Elsevier’s SciVal to analyze the department’s contribution to the SDGs through scientific publications in the Scopus database. A total of 97 out of 156 articles published by nine researchers from the department were found to contribute to various SDGs, with a significant focus on Goals 7 (affordable and clean energy), 17 (partnerships for the goals), 9 (industry, innovation, and infrastructure), and 12 (responsible consumption and production). The study highlights the department’s collaborative efforts and alignment with global sustainability goals. In addition, VOSviewer was used to map the research collaboration network within the department, revealing strong contributions to energy efficiency, sustainable technologies, and climate action. However, the department's research shows limited contribution to social SDGs such as poverty alleviation and gender equality. By mapping the university’s contributions to the SDGs, this study helps faculty members identify opportunities for targeted research collaborations, address gaps in SDG contributions, and enhance partnerships with researchers from other institutions, thus broadening the university’s impact on global sustainable development goals.
