<![CDATA[Through Making Indonesia 4.0, The Ministry of Industry responds to the demands of energy needs byinnovative renewable energy development to reduce the consumption of fossil fuels such as petroleum, naturalgas and coal with agricultural biomass waste sources. The aim of this research was to synergize waste from thebiodiesel industry in the form of sterol glycosides with purun waste from creative small-scale enterprises (SMEs)to produce renewable energy as a circular economy. The method applied was in the form of descriptive analysis, followed by identifying and characterizing waste found in the biodiesel industry, as well as various purunwastes, which were collectively sampled every day for 3 months, becoming the basis for developing innovativeproducts. Interviews were conducted on 60 purun craftsmen to confirm the circular economy program beingstudied. Observations were also made in the biodiesel industry and purun craftsmen. Data processing wasobtained from the results of experiments by making briquette products referring to several parameters whichwere the basis for standardizing renewable energy products. The synergy between the two actors, namely theBiodiesel Industry and SMEs in micro-scale circular economy activities, produced environmentally friendly- renewable energy which was very helpful for purun micro and small businesses in Purun Village, Banjarbaru,South Kalimantan. Renewable energy results were from various formulas developed with the main ingredientsderived from purun biomass charcoal and biodiesel industrial waste. The advantage of the product when severalother variables met the SNI standard 01-6235-2000 had a calorific value of 5.809 cal g-1 - 6.598 cal g-1, where5.000 cal g-1 which was the SNI for briquette heat could be exceeded. The calorific value produced is equivalentto bituminous grade coal having a carbon content of above 85%.Keywords: briquettes, calor, purun, sterol glycosides, SMEs]]>
