Abstract

Over the years, organic solid waste has become the main issue and is larger than plastic waste. According to local government data, organic waste reaches almost 50% of total waste. This research aimed to find out how effectively and efficiently cylindrical rotating perforated drum types could handle organic waste generated from households. Also, to analyze challenges, strengths, knowledge gaps, and opportunities in implementing this technology for handling organic waste. This study was conducted in South Tangerang, Indonesia, involving a residential area with a population of around 390 persons, for 24 days using rotational cylindrical organic waste processing equipment with a total capacity of 60 liters. This tool was placed in an open area exposed to sufficient sunlight and adequate air circulation. To start with, the drum was filled with starters such as soil, and then every day roughly 1 kg of organic waste was thrown inside the drum, continued by rotating it 5-6 times. After 24 days, the daily average of total mixed waste was 158 kg, while organic waste was 72.7 kg. There was a 10 kg difference between the “should-be” weight and the actual weight, which was 46.33 kg and 35.15 kg, respectively. The weight of the organic waste had dropped by 24% of the total incoming waste. It is envisaged that the community will be able to use this invention independently in order to minimize the load of urban solid waste accumulation. Furthermore, the development of this waste processing equipment is the first step toward establishing the habit of waste sorting in each citizen’s household.
