Kegiatan pengabdian masyarakat ini bermitra dengan kelompok masyarakat RT 17 RW 06 dalam penerapan teknologi filter air untuk penjernihan kolam ikan di Kelurahan Pudakpayung Kota Semarang. Lokasi mitra berada di kawasan perumahan di Kelurahan Pudakpayung. Teknologi filter air merupakan teknologi yang menggunakan tekanan dan UV untuk meningkatkan kualitas air hasil filtrasi. Masih banyak masyarakat yang belum memahami teknik pembuatan dan pengelolaan air yang berkelanjutan. Oleh karena itu dalam kegiatan ini diberikan workshop tentang berbagai ilmu tentang teknologi filter air konvensional, penjelasan mengenai operasi dan sistem pemeliharaan serta pendampingan pemasangan filter air,Metode pengabdian yang digunakan pada program ini adalah melakukan evaluasi terhadap kegiatan pemasangan filter air dan mencari alternatif baru pemecahan masalah. Hasilnya, saat ini RT17 RW 06 dapat merasakan daur ulang air yang berkelanjutan di kolam ikan masjid mereka.

Bank sampah mampu meningkatkan reduksi sampah di tingkat rumah tangga secara efektif serta meningkatkan pendapatan masyarakat secara simultan. Program pengabdian yang dilakukan di RT 03/RW 03 merupakan inisiasi pendirian bank sampah yang diharapkan dapat menjadi contoh bagi wilayah lain untuk mengembangkan bank sampah secara mandiri. Kegiatan pengabdian masyarakat terdiri dari 3 tahap yang meliputi tahap persiapan, pelaksanaan dan akhir. Pada tahap persiapan, survei lokasi dan penyebaran undangan dilakukan untuk memberikan informasi mengenai kegiatan workshop dan bimbingan teknis yang akan dilakukan. Bimbingan teknis dan workshop dilakukan dengan pemberian informasi kepada masyarakat mengenai urgensi, tata cara dan syarat pendirian bank sampah yang disampaikan oleh dosen dari Departemen Teknik Lingkungan, Universitas Diponegoro. Masyarakat terlibat aktif dalam kegiatan sosialisasi dengan mendiskusikan permasalahan yang mungkin akan mereka hadapi ketika mengembangkan bank sampah di wilayah ini. Pada tahap akhir, dilakukan monitoring terhadap pembentukan bank sampah yang dilakukan oleh kelompok swadaya masyarakat RT 03 RW 03. Setelah kegiatan ini masyarakat dapat memahami urgensi pendirian bank sampah di lingkungannya. Harapannya, muncul bank sampah – bank sampah baru yang berkembang secara mandiri. Selain itu, harapannya jumlah timbulan sampah dapat menurun karena adanya kegiatan pemanfaatan sampah di bank sampah yang terbentuk.

The addition of bentonite to fly ash can lower the permeability coefficient of the composite landfill liner. Also, the montmorillonite bentonite can bind quite a lot of water molecules during the hydration process. In this study, the effect of mixture, water content, and salinity on the desiccation cracking phenomenon in the bentonite - fly ash mixture as a landfill liner system was investigated by conducting tests such as desiccation test, water content test, and standard proctor and permeability test. The variation in bentonite levels: 0%, 15%, 20%,25% and 25% + 1 N NH4Cl solution. The result shows that the appropriate mixture is fly ash + 15% bentonite with permeability of 4,065 x 10-7. The mixture complies with local regulations where the permeability coefficient of the bottom layer of the landfill should be less than 10–6 cm/s and have a low cracking value (CIF). Furthermore, the addition of saline solution to the composite can rise the value of the optimum moisture content. However, saline conditions can decrease the value of CIF drastically

Greywater is household waste sourced from kitchens and bathrooms, except for toilets. Around 58%-85% of greywater can be generated from the total volume of household wastewater per house. It is necessary to treat wastewater before it is discharged into water bodies to prevent the adverse effects of contaminants on the environment and human health while reducing the demand for clean water. However, due to environmentally friendly, socially sustainable, and economical treatment costs, considering that greywater is produced every day and continuously, Multi Soil Layering (MSL) technology can be an alternative to remove contaminants in water. Thus, this study aims to determine the migration of COD in greywater using MSL technology. Other parameters tested were pH and temperature by taking samples of wastewater in residential areas of Semarang City. In this study, there are two stages, namely the preliminary stage and the running stage. The MSL system will use three reactors with andosol soil, apus bamboo, and coconut shell activated charcoal as mixed soil blocks (SMB). Reactor A (activated charcoal and andosol soil), reactor B (bamboo apus and andosol soil), reactor C (andosol soil, bamboo apus, activated charcoal). The results of domestic wastewater treatment using the MSL method in each of the three reactors could remove COD by 75%, 74%, and 76%. Reactor C obtained the highest COD removal efficiency compared to other reactors.

The Landoh landfillwas expired in 2022 due to the increasing amount of waste generated. The solution is to extend the service life of the landfill using the landfill mining method. The waste in the landfill is used as raw material for refuse derived fuel (RDF). The aim of the research is to find out the potential of landfill mining at Landoh landfillwhether it can be used as raw material for RDF. Primary data was taken from Landoh landfill in February 2022 with a depth of 1-2 meters and 3-4 meters from the surface of the waste generation and interviews with landfill officials. The waste samples were analyzed for waste composition, moisture content, volatile content, ash content and heating content. The waste composition is dominated by organic waste which has a large moisture content but a small caloric content. From the results of the research that the waste needs to be pre-treated (chopping and drying) for 21 days in order to fulfil the standard values of moisture content, volatile content, ash content and calorific content according to RDF raw material requirements. This method is a solution to overcoming expired landfills, reducing the volume of waste and landfill area requairements.

Examining the Water Quality Situation in Klampok River, Semarang through the Application of the NSF-WQI (National Sanitation Foundation – Water Quality Index) Model Syafrudin Syafrudin; Anik Sarminingsih; Henny Juliani; Anang Wahyu Sejati; Bimastyaji Surya Ramadan; Mochamad Arief Budihardjo; Winardi Dwi Nugraha

The Klampok River is one of the rivers that crosses the Bandungan, Bawen, Bergas and Pringapus Districts. The increase in the number of residents in the river basin which is not matched by the availability of land encourages the conversion of land functions that are not in accordance with their designation. The existence of the Klampok River as a water body receiving wastewater resulting from anthropogenic activities has caused the Klampok River to become polluted. Thus, it is important to study the water quality and water quality status of the Klampok River for nature conservation. This study aims to determine the water quality status of the Klampok River using the water quality index method, namely the National Sanitation Foundation – Water Quality Index (NSF-WQI) with reference to class II river water quality standards. NSF-WQI is a method that uses several specific parameters to determine river water quality.DO, fecal coliform, pH, BOD, nitrate, phosphate, temperature, turbidity, and total solids.The 2018 water quality index using the NSF-WQI method is in the range54.13 – 65.38with medium-good quality status. Meanwhile, the water quality index for 2019 using the NSF-WQI method is within the range35.47 – 66.60with moderate status, except for sampling point 6 which has bad status.
