Universitas Indonesia (UI), through its Tropical Renewable Energy Center (TREC), a research center under the Faculty of Engineering, has once again demonstrated its commitment to advancing renewable energy in Indonesia. TREC played a key role in drafting the Indonesian National Standard (SNI) 9233:2024, titled “Safety Requirements for Power Electronic Converter Systems and Equipment-Specific Requirements for US/US Boost Converters with a Rated Voltage of Not More than 330 V US for Household Electrical Appliances,” which was established by the National Standardization Agency (BSN).
The development of SNI 9233:2024 involved the Technical Committee 29-01, consisting of experts from various stakeholders in the electricity sector. Unlike standards that adopt international norms, this SNI was created through a self-development process, allowing it to be tailored to national needs and local conditions in Indonesia. The formulation process involved a consensus-based approach and scientific evidence, referencing multiple relevant standards rather than a single international benchmark.
Following a polling period from November 18, 2023, to December 3, 2023, the standard was approved and officially designated as SNI 9233:2024. The development stages included the SNI National Standard Formulation Program (PNPS), preparation of the Draft SNI (RSNI1), technical and consensus meetings for RSNI2 and RSNI3, finalization as RSNI4, and its determination as the Final Draft SNI (RASNI). The new standard aims to enhance the safety of DC-DC Converter equipment systems in Indonesia.
Dr.-Ing. Eko Adhi Setiawan, S.T., M.T., IPU., APEC Eng., Chairman of the SNI Conceptor Team from TREC, remarked, “This standard is based on the device developed by my research team at TREC FTUI, funded by LPDP, known as DCON, a DC-DC Converter with a power conversion capacity of 2.5-3 kilowatts. DCON can generate stable and efficient direct current electrical power for various household appliances without requiring modifications to existing equipment.”
Currently, most households in Indonesia use alternating current (AC) electricity. DCON, however, produces direct current (DC) up to 330V, making it a promising technology for early adopters. It has the potential to promote renewable energy in residential areas by utilizing battery technology charged from solar panels, fuel cells, or small-scale wind turbines. This innovation prompted TREC FTUI to propose the preparation of the standard to BSN.
Dr. Eko further explained that DCON aims to create renewable energy solutions for household electricity systems. In 2021, DCON received international recognition when the Hawai’i Natural Energy Institute (HNEI) in the United States ordered three units for its DC’s GridStart/microgrids project, which focuses on developing, testing, and evaluating renewable energy technologies. This highlights the competitiveness and international recognition of domestic products.
Established in 2015, the Tropical Renewable Energy Center (TREC) at the Faculty of Engineering, University of Indonesia, focuses on harnessing renewable energy sources to support national energy security and sustainability. TREC’s research spans nine areas: Green Building, Circular Economy and Waste Management, Smart Grids, Materials for Energy, High Voltage, Energy Storage, Energy from Biomass, Fluid Energy, and Maritime Energy.
