Abstract


Introduction: The government of banyumas district by decree number: 660. 7776/2018 concerning the management of the waste in banyumas district, in which the President's decree strongly recommends the closing of the TPA on January 2, 2019 and urges the management of waste through non-governmental groups (KSM) in trash management 3r (main, reuse and recycling). The application of 3r activities in communities is still hampered largely by the lack of awareness of people sorting waste. The world health ministry of semarang, which has an open land of 2.3 ha (2.3 ha), has an average of 4 m3/ week organic waste. Thus selecting a comprehensive waste management by using a 10-panted run way method, so each week it is used to invert waste from tub one to tub the next. Based on the above description, the formula of the problem in this study is knowing the effectiveness of the waste turning engineering tools in supporting the waste processing process. Methods: Research and Development is a research method that uses to obtain or develop products and test the effectiveness of these products. The turning tool is designed to compare the effectiveness of the waste turning process before and after using the tool. This research was conducted at a waste processing place (composter) at Campus 7 Poltekkes Kemenkes Semarang. The population in this study were all of the campus residents' solid waste generation. The sample of this study was waste in each tub (from tub 1 to 10) compost processing volume of 0.5-4 m3 / week. This study used tables analysis and the average value calculated from the results of sieving the waste. Research and discussion: The design and assembly of a waste turning tool is appropriate and can support the composting process of waste at Campus 7 Purwokerto, Health polytechnic of Ministry of Health Semarang. The volume of waste in basins 1 to 10 is on average around 0.5-4 m3 / week, in each tub per week there is a decrease in waste by an average of about 8-9%, so that starting from basin 1 with a volume of waste 4 m3 / week decreasing in the basin 10 to 0.5 m3 / week. The comparison of manual waste reversal using a machine is as follows:

Turning over manual waste takes about 5-7.5 minutes per basin with 4 workers, so it takes 50-75 minutes to reverse 10 basins. Turning the trash with a machine takes about 45-50 seconds with

Conclusion: A waste turning tool has been proven effective to assist and facilitate the process of waste reversal for the decomposition process in the composting basin at the campus 7 composting place.
