The gonggong snail is widely consumed as a part of culinary tour that currently in demand by tourists. As a result, the waste of gonggong snail shells increases. Therefore, to reduce its waste, the gonggong snail is used as a heterogeneous catalyst in making biodiesel using used cooking oil as raw material. The gonggong snail shells were calcined at 900 °C for 10 hours. The catalyst was impregnated with KOH with a concentration 0, 1, 3 and 5%, then the catalyst was calcined at 600 °C for 5 hours. The catalyst was characterized using X-Ray Diffraction (XRD) to analyze the type of mineral and the crystallinity of the catalyst. The types of minerals contained in the catalyst were calcite, portlandite and lime. X-Ray Fluorescence (XRF) was used to analyze the chemical composition of catalyst produced, and obtained oxide 3%K from the results of research with CaO and K2O of 95,912 and 2,187. The alkalinity of the catalyst was obtained from CaO catalyst 0%K, 1%K, 3%K and 5%K, were 5,3; 5,1; 5,46 and 5,8 mmol benzoic acid/g, respectively. The resulting catalyst is used for biodiesel synthesis with variations in the molar ratio of oil-methanol 1: 6, 1: 9, 1:12, 1:15 and 1:18, and the weight of the catalyst is 1%, 2%, 3% and 4%. The optimum biodiesel yield was produced at 1:15 mole ratio of oil: methanol and 3% w/w catalyst weight, which was 93,4082%, the purity of biodiesel using GC-MS was 97,39%. The characteristics of the biodiesel produced in this study were water content of 0,013% specific gravity 884 kg/m3, viscosity 3,26 mm2/s, acid number 0,053 mg KOH/g, carbon residue 0,03%, soaping number 394,74 mg KOH/g, iodine number 57,10 g iodine/100g and cetane number 47,27 some of which are in accordance with SNI 7128-2015
