Abstract

People’s growth and their activities increase waste generation. Therefore, efforts to reduce waste are needed, including community-based reduction efforts. This research is located in Gading and Dukuh Setro sub-districts in Surabaya City. The purpose of this study was to measure the potential for waste reduction and greenhouse gas reduction. Measurement of waste generation, waste composition, and waste density was based on SNI 19-3964-1994. The researcher conducted sampling in low, middle, and high-income areas, covering 83 families. Greenhouse gas emissions were estimated using the LandGEM (U.S. EPA) method based on the waste disposed at landfill, considering the existing reduction conditions and optimal material recovery. Solid waste generation in 2022 per year was 4.695,58 tons. The largest composition of waste consisted of biodegradable waste (37.13%), plastic waste (25.73%), and diapers and sanitary napkins (18.25%). The average density of loose waste was 152.42 kg/m3. The existing reduction had 1.47% waste bank reduction activity and 0.72% composting reduction activity, for a total reduction of 2.19%. The average optimal reduction was 52.7%, whereas the optimal reduction in the waste bank was 17.5%. The optimal composting reduction was 35.2%. Thus, the existing scenario in 2032 obtained reductions from total landfill gas of 725,498 Gg/year, methane of 193,788 Gg/year, carbon dioxide of 531,710 Gg/year, and NMOC of 8,330 Gg/year. Meanwhile, the optimal scenario for 2032 obtained reductions from total landfill gas of 239.067 Gg/year, methane of 63.857 Gg/year, carbon dioxide of 175.209 Gg/year, and NMOC of 0.412 Gg/year

Abstract

Peningkatan produksi minuman dapat mengakibatkan peningkatan jumlah air limbah yang dihasilkan. Hal ini mengakibatkan Instalasi Pengolahan Air Limbah (IPAL) menjalankan proses pengolahan limbah secara berkelanjutan, yang berpengaruh pada peningkatan volume sludge di IPAL. Sludge dari Instalasi Pengolahan Air Limba (IPAL) memiliki potensi untuk dimanfaatkan sebagai biobriket. Agar kualitas bionriket meningkat, limbah IPAL dicampur dengan sekam padi, serbuk kayu, dan fly ash untuk menambah nilai kalor dari bionriket tersebut. Tujuan dari penelitian ini adalah untuk menganalisis dampak dari komposisi bahan biobriket yang menggunakan campuran fly ash dan abu sekam padi, melalui metode karbonisasi pada suhu 600 derajat Celcius. Berbagai kombinasi bahan biobriket yang diterapkan dalam studi ini mencakup sludge IPAL dan abu sekam padi (100% : 0% ; 90% : 10% ; 80% : 20%) serta sludge IPAL, serbuk kayu, dan fly ash (40%:50%:10%, 60%:30%:10%, 80%:10%:10%). Analisis kualitas biobriket yang akan dilaksanakan mencakup analisis proksimat (kandungan air, kandungan abu, karbon tetap). Hasil analisis akan dibandingkan dengan Standar Nasional Indonesia (SNI) 4931:2010 mengenai Briket Batubara. Hasil penelitian menunjukkan bahwa kandungan air pada biobriket sudah memenuhi standar yang ditetapkan, tetapi kandungan abu dan karbon tetap masih belum mencapai syarat yang sesuai dengan SNI 4931:2010.

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.
