Abstract

The increasing use of plastic results in a rise in the volume of waste each year and has an impact on the environment. Pyrolysis is a method for recycling plastic waste into fuel oil. Improvements in pyrolysis design and techniques continue to be made to obtain better performance and optimal results. In this study, we compare the rate of increase in heat and volume of oil produced from two pyrolysis device designs. The alpha version is the previous version of the pyrolysis apparatus with a flat plate roof reactor and without the addition of an insulator on the tube wall. While the beta version is a modification of the alpha version with a conical roof reactor with the addition of calk material on the tube wall. Modification of the pyrolysis apparatus was also carried out in the condensation section. The beta version of the pyrolysis device shows better performance, where the reactor temperature reaches 250 ⁰C, while the alpha version, which is the previous version, reaches a maximum temperature of 220 ⁰C in a longer time. The volume of oil produced by the beta version is 0.11 mL/gram of polypropylene plastic, whereas the alpha version produced only 0.01 mL/gram for the same material. The test results for the calorific value of polypropylene (PP) plastic waste were 43.838 MJ/kg, while for acrylonitrile butadiene styrene (ABS) it was 44.772 MJ/kg.

Abstract

According to data from the Ministry of Cooperatives and UKM of the Republic of Indonesia in 2023, the contribution of Micro, Small and Medium Enterprises (UMKM) to Gross Domestic Income (GDP) reached 61%. Based on the achievement of this contribution, UMKM in Indonesia have great potential to be developed so that they can increase their contribution to the national economy. Coaching and mentoring can be carried out through the relevant agencies in their respective regions. Considering that currently in various regions Food UMKM, especially snacks, are growing rapidly, several regions have made efforts to develop Food UMKM through activities to determine regional superior food products (PUPD). For this reason, PUPD criteria are needed for UMKM and it turns out that there are many problems faced by Food UMKM in trying to meet the PUPD criteria. One of them is Dodol UMKM in South Tangerang City. Through PUPD determination activities carried out by the South Tangerang City Department of Industry and Trade together with a team of experts from the Indonesian Institute of Technology, the problems faced by Dodol UMKM in South Tangerang City have been identified, namely labor citeria, renewables, facilities and technology.

Abstract

One of the serious problems faced by the South Tangerang City Government today is waste management. According to the Tangsel City DKPP, the volume of waste is 800 tons or around 3,600 cubic meters per day. Until now, the community's waste management system is carried out with a 3R (Reduce-Reuse-Recycle) system in 49 TPS-3Rs that are spread out in every district in the South Tangerang area. The problem at this time is that some of the TPS-3R have not yet operated optimally, so the volume of waste transported to the Cipeacang TPA is still high. Management of waste into energy based on Local Waste Management Sites (TOSS) through a collaboration between STT-PLN and ITI was developed to process waste that produces pellets as an energy raw material that can be used for cooking (special stoves), processing it in a gasifier machine to get gas (syngas) ) which can be consumed by household or electricity generator raw materials. At present trials of the application of TOSS are conducted in several TPS-3Rs in Setu and Pamulang Districts. The series of activities carried out include training and mentoring processing of waste (various types of waste) into pellets, design, manufacture and testing of pellet-fueled stoves, as well as the design, manufacture and testing of gasifier machines to produce gas (syngas) which is distributed to households. The implementation of a TOSS-based waste management system is expected to be able to solve the waste problem in South Tangerang City and get added value through the conversion of waste into energy that can be utilized by the community.
