Abstract

Banyaknya limbah pertanian yang tidak dimanfaatkan oleh petani dapat menyebabkan terjadinya pencemaran lingkungan. Salah satu limbah pertanian yang biasa dibuang dilahan pertanian yaitu limbah sekam padi. Sekam padi merupakan kulit pembungkus padi yang dipisahkan dari biji padinya. Limbah sekam padi ini dapat dimanfaatkan sebagai bahan pembenah tanah dengan mengubahnya menjadi biochar. Biochar limbah sekam padi dapat meningkatkan kandungan karbon dan nitrogen dalam tanah. Desa Sukadana merupakan salah satu desa yang memiliki potensi pertanian yang baik, disisi lain Masyarakat belum memanfaatkan limbah pertaniannya. Oleh karena itu kegiatan pengabdian ini dilakukan dengan tujuan untuk meningkatkan pengetahuan petani dalam memanfaatkan limbah sekam padi sebagai bahan baku pembuatan biochar. Kegiatan pengabdian dilakukan dengan metode edukatif dan sosialisasi aktif dengan diskusi dan sharing yang melibatkan seluruh peserta pengabdian. Dari kegiatan pengabdian yang dilakukan telah diketahui bahwa kelompok tani 1.) Sebagian besar anggota kelompok tani belum bisa baca tulis; 2.) kegiatan pretest dan posttest perlu dilakukan dalam bentuk diskusi tanpa adanya kegiatan tulis menulis; 3.) Pengetahuan tentang pemanfaatan limbah pertanian yang rendah; 4) Setelah adanya sosialisasi ini, masyarakat semakin paham dalam mengelola limbah pertanian, terutama sekam padi; 5.) Perlu adanya tindak lanjut praktik pembuatan biochar limbah pertanian. Socialization of the Use of Rice Husk Waste as Raw Material for Making Biochar Abstract: The large amount of agricultural waste that is not utilized by farmers can cause environmental pollution. One of the agricultural wastes that is usually disposed of on agricultural land is rice husk waste. Rice husks are the skin covering the rice which is separated from the rice grains. This rice husk waste can be used as a soil amendment by turning it into biochar. Rice husk waste biochar can increase carbon and nitrogen content in the soil. Sukadana Village is one of the villages that has good agricultural potential, on the other hand, the community has not utilized its agricultural waste. Therefore, this service activity was carried out with the aim of increasing farmers' knowledge in using rice husk waste as raw material for making biochar. Service activities are carried out using educational methods and active socialization with discussions and sharing involving all service participants. From the community service activities carried out, it is known that the farmer groups 1.) Most of the members of the farmer groups cannot read and write; 2.) pretest and posttest activities need to be carried out in the form of discussions without any writing activities; 3.) Knowledge about low utilization of agricultural waste; 4) After this socialization, people understand more about managing agricultural waste, especially rice husks; 5.) There needs to be follow-up on the practice of making biochar from agricultural waste.

Abstract

Hazardous and Toxic Waste (B3) from laboratories, especially those containing heavy metals (Hg and Cr) and several physical factors such as pH, TSS, and color, poses a serious threat to the environment if not managed properly. This study aims to estimate the adsorbent for the development of laboratory-scale wastewater treatment equipment based on the adsorption method using biochar, zeolite, and activated alumina. The research method involves preparing adsorbent materials, testing their effectiveness in reducing the content of heavy metal pollutants, and designing a waste treatment device. The combination of biochar, zeolite, and activated alumina was chosen due to their complementary abilities in removing heavy metal content from B3 waste in the Soil Chemistry laboratory. The treatment results showed significant reductions (p < 0.05) in heavy metal (Hg and Cr) levels in laboratory waste. The optimal combination is a formulation of biochar, zeolite, and activated alumina (1:1:1). Innovations in adsorbent technology for processing heavy metal waste in soil chemistry laboratories can be applied and further developed to create a clean and healthy environment.
