Abstract

Plastic waste accounts for 17% of the staggering 68.5 million tons of national waste, driven by the convenience-seeking lifestyle leading to increased single-use plastic consumption. Addressing this issue necessitates policies and exceptional efforts to manage plastic waste from its origins to disposal. One significant effort involves converting plastic waste into oil through pyrolysis, a high-temperature decomposition process without oxygen. This study focuses on Pondok Pesantren At. Tajdid, facing mounting plastic waste issues from resident students, that aim to convert plastic waste into oil using pyrolysis. Technical specifications describe a pyrolysis apparatus comprising a combustion furnace, pyrolysis tubes, a condenser, and related components. This innovation^s strengths lie in its ability to process PP, PET, plastics into fuel oil, providing an alternative energy source. Innovative pyrolysis equipment, utilizing electrical energy unlike its LPG-powered counterparts, was implemented at SMA At Tajdid Cepu. The process involves preparing plastic, feeding it into the reactor, running the pyrolysis apparatus at 500-700 Celcius for approximately 4 hours to yield oil. The apparatus accommodates a maximum of 500 grams of mineral water bottle plastic waste. Through experimentation, 350 grams of plastic produced 270 ml of fuel oil, translating to approximately Rp 11,565 per kilogram of plastic waste processed. The innovation showcases the potential to provide an alternative energy source while managing plastic waste sustainably.
