- Manage and plan several activities regarding develop sense of social and nationalisme including discussion, agitation and propaganda, and media infographics- Organize the mass, spread agitation and propaganda, and make critical studies of public policy.

- Developed 3 Standard Operating Procedures (SOPs), 7 Work Instructions, 4 Standard Parameters, and 3 Forms related to the maintenance of Solar Power Plants in mining area, a new renewable energy project by PT KPP Mining, ensuring document compliance with manual book, industry standards and national and international regulations.- Executed the implementation of PLTS maintenance activities according to the SOPs, covering all components thoroughly.-Analyzed and processed monitoring data from the solar photovoltaic system to evaluate performance metrics and track reductions in fuel consumption and carbon emissions.- Designed an automation system for cleaning PV modules using a 180-degree automatic sprinkle technique, which simultaneously cleans and cools the modules, thereby increasing efficiency up to 15%.- Conducted feasibility study for the renewable energy project plan for Wind Power Plants as a retrofit for the water truck filling system using actual on-site data.- Designed and implemented an automatic water filling system for mining area water trucks using microcontroller technology, without modifying the trucks. This system facilitated operator ease and reduced water and electricity waste.- Performed load flow analysis using ETAP for the electrification of a workshop site, transitioning from diesel generator power to PLN grid connection. Considered future load demands to determine optimal cable sizing, transformer selection, and load distribution.- Conducted a comprehensive study on hydrogen energy with IFHE (Indonesia Fuel Cell and Hydrogen Energy), discussing electrolysis, hydrogen storage, hydrogen transmission, fuel cells, hydrogen utilization and global developments in hydrogen energy.

- Collaborate with teammates to perform predictive, preventive and corrective maintenance.- Repired the SMC machine crane by rewiring the old cable with the new ones.- Learned about PLC Siemens using TIA Portal V15 such as configuration, PLC program, and interlock to safety indcator.- Analyze problems with the PLC program to make improvements so that the sequence runs well.- Learned read single line diagram wiring to troubleshooting.- Observed engineer while configurate the drive, setting parameter, identification run, and rotation test to intergrate the drive and pump motors.
