Phosphorus in wastewater accelerates eutrophication in water body. Textile wastewater is one of contributors to the phosphorus loading into water body which promotes the growth of algae, reducing the oxygen content and detrimental to surface water ecosystem. Myriad existing treatments for phosphorus removal have been developed but it requires a high cost treatment and maintenance. Rock filter system emerged as one of the alternative method for phosphorus removal from wastewater with steel slag as the filter media. However, application of the system in treating industrial wastewater is still unclear especially in big scale application and requires extensive study. This study is done to provide solution of phosphorus loading from textile wastewater using steel slag as filter material and to investigate the removal capacity of steel slag with high calcium and low ferum content. The steel slag was analyzed using XRF for its composition and to ensure the steel slag has high Ca content. Then, the aerated steel slag filter system was set-up on the site of textile industry for a month and analyzed according to parameter of pH, alkalinity, COD, DO, temperature and TSS. The result from this study showed that the aerated high calcium low ferum steel slag filter has a high efficiency of phosphorus removal rates varied from 35% to 67% in treating textile wastewater. It was found that aerated steel slag system was efficient in phosphorus removal by using industrial wastewater

The Impact

Abstract. Livestock waste is one of the contributors to greenhouse gas emissions, therefore it needs proper handling so that the impact on the environment can be minimized. Therefore, socialization and education on waste handling is carried out in an effort to reduce greenhouse gas emissions. Socialization to farmer is done online using whatsapp and zoom meetings platform. Partner are farmers from Cileles and Cilayung Villages, Jatinangor Sumedang District. Waste treatment extension activities as an effort to reduce greenhouse gas emissions are carried out by creating audio visuals in the form of videos and e-flyers uploaded to the media youtube and whatsapp partner groups. In general, farmers understand that the waste generated from their livestock activities must be managed properly, but they do not understand that the impact of improper management will result in greenhouse gas emissions. After extension activities was carried out, there was an increase in farmers' knowledge, both on the potential of livestock waste is one of as a greenhouse gases contributors and good waste processing techniques.Keywords: animal waste, organic fertilizer, greenhouse gasAbstrak. Limbah peternakan memberi kontribusi yang cukup besar terhadap peningkatan emisi gas rumah kaca, diperlukan penanganan yang tepat sehingga dampak terhadap lingkungan dapat diminimalkan. Oleh karena itu, dilakukan sosialisasi dan edukasi penanganan limbah ternak sebagai upaya mengurangi emisi gas rumah kaca. Mitra merupakan peternak yang berasal dari Desa Cileles dan Desa Cilayung Kecamatan Jatinangor Sumedang. Kegiatan penyuluhan pengolahan limbah sebagai upaya mengurangi emisi gas rumah kaca dilakukan dengan membuat audio visual berupa video dan e-flyer yang diunggah ke media youtube dan whatsapp grup mitra. Metode yang digunakan adalah penyuluhan secara daring menggunakan media zoom meeting. Secara umum peternak mengerti bahwa limbah yang ditimbulkan dari kegiatan usahanya harus dikelola dengan baik, namun mereka tidak memahami bahwa dampak pengelolaan yang tidak tepat akan mengakibatkan emisi gas rumah kaca. Setelah dilakukan penyuluhan, terdapat peningkatan pengetahuan peternak baik potensi limbah ternak sebagai kontributor gas rumah kaca maupun teknik pengolahan limbah yang baik.Kata Kunci: limbah ternak, pupuk organik, gas rumah kaca
