Modeling of Waste Processing Tools for Waste Management in Karanganyar Regency

Waste management is a pressing issue today, with a significant amount of waste remaining unaddressed from its source, including at the Sukosari Landfill in Karanganyar Regency. This study aims to identify an effective, efficient, and environmentally friendly incineration-based waste processing tool to overcome waste problems in Karanganyar Regency specifically, and in other regions generally. The method employed involves comparing two waste processing tools: an incinerator and the "Predator Sampah Sedeng" tool. The comparison methodology includes tool specifications, criteria assessment, and scoring evaluation. The environmentally conscious community of Sedeng Hamlet, Tawangmangu, created the "Predator Sampah Sedeng" waste processing tool for waste management at the smallest community level, such as Neighborhood Associations (RT), Community Units (RW), and villages. This waste processing tool is capable of handling all types of waste, including those currently unmanageable like used diapers and glass fragments, thereby enabling complete waste management at the village level. The "Predator Sampah Sedeng" tool is a result of creativity and innovation, utilizing waste (used oil) as fuel, is environmentally friendly, can be made from recycled materials, and is capable of generating energy that can be used to support other activities, thus providing appropriate energy. From waste to blessing for all, it is capable of providing economic value for both the implementers and the environment carrying out waste processing activities. The conclusion drawn from the tool specifications, comparative criteria assessment, and scoring values is that the "Predator Sampah Sedeng" tool is more effective, efficient, and environmentally friendly. This includes: 1) effectiveness, capable of processing 1,500 kg of waste per day within 8 hours, and capable of processing diapers, styrofoam, and glass; 2) efficiency, as the "Predator Sampah Sedeng" tool is very easy to use, has low operational costs due to using waste (used oil) as fuel, and has a very affordable manufacturing cost of Rp. 40,000,000. Additionally, the heat produced is utilized for baking food, drying maggots, and saunas (hot steam baths), while the generated electricity is stored in three 100 A batteries; 3) environmental friendliness, as the emitted smoke does not pollute the environment due to being equipped with a 10m chimney from ground level with a simple filter, and the resulting ash by-product can be utilized as a planting medium and has economic value for sale.
