Abstract

Pertambahan jumlah penduduk di berbagai wilayah secara umum telah menimbulkan masalah sampah. Studi sebelumnya menunjukkan bahwa pola pengelolaan sampah yang dilakukan responden di Kota Salatiga adalah pembuangan sampah. Pada dasarnya, pembuangan sampah makanan, merupakan aktivitas yang menimbulkan emisi, dan merugikan secara ekonomis karena sampah makanan tersebut masih mengandung zat-zat yang memiliki nilai gizi. Selain rumah tangga, area sekolah merupakan salah satu sumber potensial penghasil sampah makanan dari kantin yang setiap hari dikunjungi siswa-siswi sekolah. Oleh sebab itu, diperlukan upaya mengelola sampah makanan dari kantin sekolah guna mengurangi risiko pembuangan sampah makanan dalam jumlah besar. Kegiatan Pengabdian kepada Masyarakat ini dilakukan untuk mendorong keterlibatan siswa sekolah Adiwiyata di Kota Salatiga, dalam hal ini adalah SMAN 2, dalam proyek pembuatan pakan ikan dari enceng gondok dan sampah makanan kantin SMAN 2 sebagai upaya sekolah dalam menghasilkan produk inovatif ramah lingkungan. Kegiatan ini dilakukan dengan pendekatan partisipatif dan dapat mendorongketerlibatan guru dan siswa dalam menuangkan gagasan, merencanakan kegiatan, melaksanakan kegiatan, dan melakukan evaluasi atas proyek yang dilakukan. Proyekyang dilakukan siswa juga membuktikan bahwa sampah makanan dapat diolah menjadi pakan ikan. Pengolahan sampah makanan menjadi produk yang bermanfaat sangat memungkinkan dengan ujicoba yang lebih lama dan mempertimbangkan penggunaan bahan-bahan yang mudah ditemukan dalam kehidupan sehari-hari.

Abstract

Dairy farming's waste contributes to greenhouse (GHG) gas emission, and its conversion into biogas is of potential benefit to reduce emission while providing alternative energy for the dairy farmers. Although biogas conversion has been conducted in Banyudono, Semarang Regency, not all dairy farmers are interested in this biogas processing, and it seems to be related to the question of the benefit they would receive. This research aims to explain the management of the waste of dairy farming in Banyudono and a feasibility study on dairy farming in Banyudono, if biogas processing is not to be included and along with biogas processing. This study combines qualitative and quantitative approaches by conducting interviews, direct observation, documentation, and a feasibility study on biogas processing. This study finds that 8,400 kg of cow manure and 4,950 liters of urine are produced every day, by only 5.76% is processed into biogas, 11.25% is processed into manure, while 82.98% of the waste is left unused. The feasibility study indicates that biogas processing tends to increase the benefit received by independent farmers instead of the member of the dairy farmer group discussed in the study. Furthermore, our study reveals issues regarding the dairy farmers' environmental awareness, poor management of biogas distribution on the farmer group level, and technology adoption problems. Finally, a model of integrated farming system is composed to address the issue of waste management in Banyudono.

Abstract

The Indonesian batik plays a crucial role in supporting the country's economy. However, its production often leads to environmental problems. As sustainable development implies the need for economic benefits equally accessible by all people without compromising the environment for the future of the next generation, the sustainability of batik means that batik, as a cultural product, should be preserved, and its production can bring economic benefits without harming the environment. Therefore, environmental issues related to batik should be overcome. Studies addressing the problem of batik wastewater have been conducted; however, adsorption technology is gaining popularity due to the benefits it offers. This review examines the characteristics of batik wastewater, identifies existing batik wastewater treatment technologies, and evaluates the potential of adsorption technology for batik wastewater treatment. This literature review was conducted using Science Direct and Directory of Open Access Journals (DOAJ) search engines, which initially collected 78 articles, and finally, 58 articles were found to be suitable for the review. An Excel-based matrix was then created to analyze the literature manually. It is found that batik wastewater is usually alkaline; the Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Total Suspended Solids (TSS) usually exceed the quality standard regulated by the Indonesian government, and are usually non-biodegradable, as indicated by the low BOD/COD ratio. Adsorption is widely applied, economically feasible, and can be easily operated by batik entrepreneurs. The performance of this technology is best when combined with other processes.

Abstract

Badung Regency is the fourth city which is the largest waste producer in Bali Province, with the amount of waste production in Badung Regency in 2022 reaching 119,475 tons per year. On the other hand, the generated waste is only disposed of at the Suwung Final Disposal Site (TPA), without prior processing. However, as of March 2023, the Bali Provincial Government has begun to gradually close the Suwung TPA, due to waste overcapacity, as evidenced by the presence of rubbish piles as high as 25 meters. In response to this, the Badung Regency Environmental Service (DLH) built the Mengwitani Integrated Waste Processing Site (TPST), where waste is processed into Refuse Derived Fuel (RDF) with the aim of reducing waste generation in Badung Regency. This research aims to evaluate the process of processing waste into RDF at the Mengwitani TPST, so that it can be seen how much waste generation can be reduced through RDF processing at the Mengwitani TPST. The method used is a quantitative method, with a mass balance analysis approach. Therefore, it was found that processing waste into RDF was carried out by going through 5 stages of filtering or segregation. So, after processing the waste into RDF, it was found that the potential for waste reduction at the Mengwitani TPST reached 72% every day, and on the other hand, the RDF produced by the Mengwitani TPST had been adjusted to standards, namely SNI 8966:2021.

Abstract

Population growth has an impact on land use change which leads to various environmental issues, including the clean water needs. The Community-Based Drinking Water and Sanitation Provision (PAMSIMAS) is one of the government's programs aimed at fulfilling the clean water and sanitation needs of community. Although there are still implementation problems, this program has shown positive benefits and impacts in various regions. This research aims to explain the achievements of the PAMSIMAS program in Temanggung Regency as a government effort to improve the people welfare. This is a quantitative study using secondary data and analyzed using descriptive analysis. The results of the research show that the realization of PAMSIMAS in Temanggung Regency for drinking water is considered good, with the lowest being around 75%, and some achievements exceeding the target of 100%. PAMSIMAS realization for sanitation is still fluctuating with low sanitation realization in three sub-districts, namely Bansari sub-district (27.13%), Wonoboyo sub-district (8%), and Tretep sub-district (6%). The low level of sanitation is caused by the low economic status, weak social norms, and weak social capital. Further studies are needed to find the factors causing the low sanitation realization in these sub-districts in order to find the best solution.

Abstract

Salatiga merupakan wilayah yang strategis di wilayah Yogyakarta, Surakarta, dan Semarang, sehingga seringkali menjadi tempat persinggahan para wisatawan yang melintas ke tiga kota tersebut. Sebagai akibatnya, warung kuliner di kota Salatiga juga berkembang pesat dari waktu ke waktu yang berimplikasi pada potensi timbulan sampah makanan (food waste). Namun, studi mengenai sisa makanan tersebut masih terbatas. Penelitian ini bertujuan mengeksplorasi produksi makanan dan sampah makanan yang dihasilkan oleh warung kuliner dan konsumennya di Kota Salatiga. Studi dilakukan dengan metode kualitatif pada lima warung kuliner yang berjualan sore hingga malam hari di Kota Salatiga. Hasil penelitian menunjukkan bahwa sampah makanan yang dibuang oleh warung kuliner adalah sampah makanan yang berasal dari bagian yang tidak dapat dimakan seperti kulit telur, minyak jelantah, dsb. Namun ada warung kuliner yang menunjukkan praktik baik dengan menyajikan porsi yang tepat bagi pembeli, sehingga memperkecil potensi menyampah. Selain itu, makanan yang tidak dihabiskan biasanya dibawa pulang oleh pembeli, sehingga tidak menjadi sampah.
