LPG (Liquefied Petroleum Gas) as the main fuel for household use in Indonesia is a big burden on the Indonesian national budget for its import. This study aims to find a recommendation for energy substitutes to ease the import of LPG. Five types of gas-fueled and electric stoves were used to compare their performance. The gas stoves were tested subject to Indonesian standards SNI 7368:2007 and fueled with LPG and natural gas (NG). The electric stoves, varied from infrared (IRD), hot-plate (PLT), and induction (IND) types, were tested according to IEC 60335-2-6:2010. Heating rate, power consumption, efficiency, safety and specific costs were examined by heating 3.7 kg of water in a 24 cm stainless steel pot to 90 °C. NG stove showed the best heating rate at 8.54 °C/min, followed by LPG, IND, IRD and PLT. In terms of safety, the induction stoves were on top because the surface cools down quickest. On the other hand, natural gas stove delivered the best specific costs at Rp. 0.414/kJ. However, the infrastructure supporting NG is still limited available in Indonesia, thus the implementation of induction-type stoves is deemed the most feasible.
