Abstract

Pneumatic and hydraulic systems are technologies that are widely applied to industrial machinery and automation systems, so mastering them is an important competency for Vocational High School (SMK) students in the field of mechanical engineering. However, the limitations of practice-based learning cause students' understanding and skills of the system to be not optimal. This community service activity aims to improve the competence of vocational school students through applicable and practice-based pneumatic and hydraulic system training. The method of implementing activities includes the preparation stage, the implementation of training through lectures and direct practice, and the evaluation of training results. The results of the activity showed an increase in students' understanding of the basic concepts, components, and working principles of pneumatic and hydraulic systems. In addition, students' practical skills in assembling and operating systems have also improved. This training makes a positive contribution to increasing the readiness of vocational school students to face the needs of the industrial world and supports the strengthening of vocational education through synergy between universities and vocational schools.

Abstract

Perkembangan zaman dan teknologi saat ini menjadikan banyak perusahaan industri yang memanfaatkan logam sebagai bahan utama bahan baku produksinya, industri di bidang pengecoran logam sangat banyak memanfaatkannya sebagai sumber mata pencaharian masyarakat dengan kemampuan khusus. Pembuatan Profil Sudut Pembengkok Pipa 900 untuk melengkapi peralatan Praktikum di Politeknik Negeri Banjarmasin khususnya pada pembengkokan pipa. Proses pembuatan profil sudut pembengkok pipa dilakukan dengan proses pengecoran logam menggunakan cetakan pasir. Bahan profil terbuat dari batok aluminium bekas kaleng minuman dan bekas dudukan kampas rem sepeda motor. Kekuatan tarik bahan profil sudut pembengkok dilakukan dengan pengujian tarik. Dengan hasil dari pengujian tarik dengan rata-rata 77,440 MPa.Kata kunci: Pengecoran Logam, Aluminium, Cetakan Pasir, Profil Sudut, Pembengkok Pipa

Abstract

The use of electrical energy is a vital need for MSMEs, but dependence on conventional energy leads to high operational costs. As a tropical country, Indonesia has abundant solar energy potential with an average irradiation intensity of 4.80 kWh/m²/day. However, its utilization is still minimal. Solar lighting technology can be an efficient, environmentally friendly, and energy independence solution, especially in areas with limited access to electricity. The main problems are the high cost of electricity, dependence on PLN, lack of use of renewable energy technology, and limited capital and knowledge. The solutions offered include solar lighting installation, training in use and maintenance, and the provision of affordable financing schemes. The implementation method includes survey, training, installation and trial. MSME players can now benefit from the use of solar lights, which are not only cost-efficient, but also support the sustainability of their businesses by reducing their reliance on more expensive conventional energy sources. In addition, the use of renewable energy technology also supports the principles of sustainability and environmental friendliness, which are in line with the goal of developing a greener and more sustainable business.

Abstract

The steel hardening process through hardening aims to improve the hardness of steel by rapid heating and cooling. The refrigerant media used, such as brine, plain water, and oil, have a significant influence on the hardness of steel. This study aims to analyze the effect of refrigerant media variations on steel hardness after the hardening process. The research method used is a laboratory experiment, in which the steel specimen is heated to an austenitization temperature and cooled with three different cooling media. The hardness of the steel was tested using the Rockwell hardness test, and the microstructure results were analyzed with a metallographic microscope. The gap of this study is the lack of studies related to the influence of refrigerant media variations on steel hardness with a focus on application to crowbars. The results showed that the brine medium provided the highest hardness (98.7 kgf/mm²), followed by ordinary water (98.1 kgf/mm²) and oil (96.2 kgf/mm²). These results suggest that faster refrigerant media, such as brine, produce higher hardness. This study provides insight into the selection of the optimal refrigerant media to increase steel hardness, especially in industrial applications that require hard and durable steel.
