Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

Acid Mine Drainage (AMD) is a liquid waste caused by mining industrial activity. AMD has a very acidic pH and contain heavy metals, such as Fe and Mn. Therefore, the solution of this global problem should be investigated. One of the ways to treat AMD is by adsorption using activated carbon. Activated carbon is made from coals through chemical activation process using ZnCl2 with a composition of 40% ZnCl2 and 60% coals. Afterwards, carbonization process was performed at 500oC for 120 minutes. The synthesis result of activated carbon was analyzed for iodine numbers and characterized using BET. The activated carbon had maximum iodine numbers of 1373 mg/g and maximum surface area of 667 m2/g. Ion content in Fe and Mn in AMD was adsorbed using activated carbon with several variations of activated carbon grain size, mass, and contact duration. The results showed maximum adsorption of 100% for Fe and 56% for Mn, with increased maximum pH from 3 to 6.2. Kinetic and adsorption study was conducted on contact duration variation and obtained that adsorption process followed Langmuir isothermal model with adsorption capacity of 2.54 mg/g.
Cisolok is a geothermal field located in South-West area of Java Island, Sukabumi Residence having energy potential for the future. A geological structure research has been conducted to create geology model and to predict geothermal system of the area. By measuring faults and fractures of geological structures in the area, it can be predicted the geothermal system and modelling the geology of the area. Researchs by several experts indicate that Cisolok is part of Cisolok-Cisukarame geothermal area, particularly as an outflow zone, having potential of medium enthalpy. Geothermal surface manifestations appear following the direction of geological fault structures. Using surface water temperature of hot springs and geysers reaching above boiling point, the reservoir is predicted to reach subsurface temperature of approximately 185-212°C
