Abstract

Surabaya, the second largest city in Indonesia, faces significant environmental challenges, particularly waste management. To address this issue, the Surabaya City Government, through the Surabaya City Environmental Service (DLH), has introduced an innovative solution: the waste bank program. This practical work aims to evaluate the potential for waste reduction in East Surabaya and South Surabaya using the 3R (Reduce, Reuse, and Recycle) system facilitated by the waste bank program. The waste bank involves the sorting and collecting of recyclable and reusable waste with economic value. Initially, waste sorting was done at the waste bank, but there has been progress. Now, many customers are sorting their waste by type at home. However, some waste bank administrators still need to sort waste on-site due to some customers' inability to do so. The waste bank program also maintains organized weighing and management procedures. All transactions are meticulously recorded in both cash books and passbooks. The results of this program show that waste reduction in active waste banks in East Surabaya and South Surabaya is 0.088%, while the overall waste reduction managed by the Environmental Service (DLH) is 0.571%. To enhance the effectiveness of the waste bank program, it is essential to conduct awareness campaigns to educate the public on the importance of waste management. Additionally, offering rewards to customers could further motivate them to actively participate in the waste bank program.

Abstract

The Kali Tebu River in Tanah Kali Kedinding Village, Kenjeran District, Surabaya City, is often used by many people to defecate. Data collected by the Tanah Kali Kedinding Community Health Center in 2023 shows that 48 heads of families (KK), or 0.30% of the total population, are still involved in Open Defecation (Open Defecation) in waterways that flow directly into the river. into the Kali Tebu River, this can pollute river water, changing the quality of river water. The aim of the research is to analyze the results of river water quality tests, water quality status. In this research, a questionnaire was filled out to find out the community profile, then tested the parameters based on Minister of Environment and Forestry Regulation No. 68 of 2016 which consists of TSS, pH, BOD, COD, Fatty Oil, Ammonia, and Total Coliform. Then compare the quality status of the Storet method and the Pollution Index (IP) which is guided by Minister of Environment Decree No. 115 of 2003 with River Water Quality in accordance with PP RI No. 22 of 2021 . The test results for the TSS, BOD, COD, Ammonia, Fatty Oil and Total Coliform parameters of the Kali Tebu river do not meet the class quality standards in accordance with Government Regulation no. 22 of 2021, while the pH, COD and fatty oil parameters are compliant. Then the water quality status in the Kali Tebu River was determined using the storet method at points 1 – 3, all of which were included in the heavily polluted category with result values of -102, -100, -98. Meanwhile, to determine water quality status using the average Pollution Index at points 1 - 3, it is included in the heavily polluted category with PIj values 10, namely 20, 22, 23.
