Abstract

Hajimena Village is part of the Natar District which is directly adjacent to the Bandar Lampung City area, so that garbage disposal also enters from Bandar Lampung. The introduction and application of the 3R (Reduce, Reuse, Recycle) principle or the reduction, reuse and recycling of waste is one of the approaches in waste management. Inorganic waste can be converted into handicrafts that can be sold, especially plastic waste can be or processed into paving blocks. The Department of Chemistry Faculty of Mathematics and Natural Sciences University of Lampung, Community Service Team carried out community service activities aimed at increasing public awareness and participation in managing waste independently, reducing plastic waste and being a source of income for BUMDES. The activity of making paving blocks with variations of plastic waste, used oil, rice husks, and sand using simple technology and tools. The results of community service activities can be seen from the evaluation results in the form of measuring the achievement of specific instructional goals (ICT) from activities carried out using pre-test and post-test given to participants. The results show that there has been an increase in ICT for each participant after this service activity was carried out, it can be seen that each ICT has increased with an average increase of about 60.4%. This shows that public knowledge about plastic waste has increased significantly. So that the processing of plastic waste can be an opportunity to increase the income of the Hajimena village community.

Abstract

One of the main problems faced by farmers in Lampung today is the limited or scarcity of subsidized fertilizers. Meanwhile, there is an interesting phenomenon that has occurred on campus, including at FMIPA, University of Lampung (Unila), that about waste. So far, organic waste in the Faculty of Mathematics and Natural Sciences, Unila, has not been utilized optimally. The organic waste is only collected and deposited at the Integrated Waste Management Site (TPST) at Unila to be sorted and then taken to the Final Disposal Site (TPA) of Bandar Lampung City. These conditions prompted us, as academics at the University of Lampung, to be moved to carry out a community service program with the theme "Conversion of organic waste in the Faculty of Mathematics and Natural Sciences at the University of Lampung into Liquid Organic Fertilizer (POC) using solid liquid (SL) techniques." This PKM activity aims to process organic waste into liquid organic fertilizer. The processing of organic waste into liquid organic fertilizer is carried out using the soluble liquid technique, in which the organic waste is chopped and then pressed using a press machine, the pressed liquid is added to the starter solution so that the solid particles can dissolve. The dregs resulting from the press are also added to the starter solution so that the dregs can be used as animal feed or compost. The resulting product is applied to plants around FMIPA Unila. The results of this PKM activity were in the form of 60 liters of liquid organic fertilizer (POC) from 100 kg of organic waste, in other words, a yield of 60% was obtained. The resulting POC was then applied to plants in the FMIPA environment. Apart from products in the form of POC, this activity was also able to slowly change the behavior of the Unila FMIPA academic community towards existing organic waste. It is hoped that regular coaching will change the FMIPA environment to be cleaner, healthier and greener. The liquid organic fertilizer produced can also be packaged to be further sold to farmers at affordable prices, so as to increase the economic value of organic waste which has not been utilized so far and also increase the income of some of the education staff in FMIPA Unila.
