Abstract

The volume of municipal waste has become a national problem so far, so a solution is needed to reduce the waste problem. One solution to reduce the volume of municipal waste is to burn waste. However, the combustion needs to be designed to take advantage of the heat generated by combustion. In this study, the process of burning waste with various types of waste materials was carried out. The heat of burning waste is used to evaporate 1 liter of seawater and the seawater vapor is cooled to produce distilled water. The volume of distilled water and the precipitated salt were weighed. The results of the research from the variation of 6 types of waste materials obtained that the type of clothing waste material gave the fastest time, which was 43.75 minutes, the amount of distilled water was 931 ml, and salt deposited as much as 30 grams. The test results on distilled water showed that almost all parameters met the requirements of drinking water and obtained a salt content of 84%. Further processing by adjusting the hardness is needed to process distilled water into clean water and the addition of iodine can be considered to produce iodized salt.

Abstract

Plastic waste has become a significant problem of environmental pollution in recent decades. The nature of plastic waste is complicated to decompose; it has worsened the environmental situation, especially if it is not taken seriously immediately. One approach that can be taken to overcome this problem is to provide counseling to the public so that they do not dispose of plastic waste carelessly. The community service program is a forum for academics to participate and provide counseling about the management of plastic waste. The purpose of this community service program is to counsel the Panjangrejo community about how to manage plastic waste properly. This counseling program began with discussions with the Panjangrejo sub-district officials and related parties, then continued with planning the timing of the extension. Residents and community elements are fully involved, so this program can run smoothly. The counseling program was carried out in three villages, namely the villages of Semampir, Gunung Puyuh, and Krapyak Wetan, and this program was held at night from 20.00 WIB to 22.00 WIB. The outreach results showed that people's knowledge about the dangers of plastic waste and how to manage it could be significantly improved (p < 0.05). In general, this extension program successfully increased respondents' knowledge from "not knowing" to "knowing better" about the dangers and how to manage plastic waste.
