Waste management improvement with software application at Wringinsongo Village, Tumpang Regency, Malang

Wringinsongo Village, Tumpang Subdistrict, Malang Regency maintains a clean environment through environmentally friendly waste management. One of Wringinsongo’s BUMDes (Village-Owned Enterprises) is the Waste Bank, which uses waste as a potential sector. It needs to get special attention related to its governance, because the recording is still less effective and there are often calculation errors caused by the recording system using paper. Based on these conditions, it is necessary to develop an application to help record transaction activities at the Waste Bank. The Wringinsongo Village Waste Bank application can be accessed on both the web platform and Android mobile devices, based on the ease of access to the system by village managers and officials. After developing the application, socialization and training were conducted to the Waste Bank manager and village officials to provide information on how to use the application. After three months of use, feedback was taken to get responses related to the use of the application. The result is that BUMDes managers find it easy to record and obtain accurate and faster calculation results.

on its function, BUMDes is a pillar of economic activity in the village that functions as a social and commercial institution (Rosyadi et al., 2021) that can improve the economic standard of the village community (Aprillia et al., 2021).BUMDes as a social institution favors the interests of the community, as a commercial institution it aims to make a profit through offering local resources (goods and services) to the market.This can have an impact on increasing the original village income (PADes).The business character of BUMDes can be customized based on the needs of the local community (Ibrahim et al., 2022;Moita, 2022).From the description above, it can be understood that villages can play a role in developing themselves through BUMDes, as happened in Wringinsongo Village, which has a BUMDes with one of its business units, namely the Waste Management Unit.The function of waste management at the village level can have a good impact on environmental health and improve the economic level of village communities (Putra & Ismaniar, 2020).
Wringinsongo Village is a village located in Tumpang District, Malang Regency.Wringinsongo Village can optimize the use of the waste classification unit, which can be seen in Figure 1, including to meet the needs of residents.Because the waste management mechanism requires installation and operational costs, the waste management unit naturally sets a certain tariff.Currently, the BUMDes waste management unit of Wringinsongo Village, appointed by Wringinsongo Village officials, has approximately 110 waste bank customers divided into 6 RW in Sumber Ringin Hamlet.It is expected that in the following years, other hamlets in Wringsinsongo Village can contribute to utilizing the waste classification facilities owned by the Village.
