Abstract

Canang sari merupakan simbolik dari kehadiran Ida Sang Hyang Widhi. Sebelum memulai kegiatan belajar, sekolah di Bali selalu menghaturkan canang sari di Pura Sekolah. Canang sari menjadi sampah ketika sudah selesai digunakan dalam kegiatan persembahyangan di sekolah. Tujuan dari pengabdian kepada masyarakat ini adalah siswa mampu melaksanakan siklus canang sari. Pelaksanaan pengabdian dilakukan selama 4 bulan dengan tahapan observasi, persiapan dan perancangan kegiatan, pelaksanaan kegiatan, dan evaluasi. Hasil dari kegiatan pengabdian kepada masyarakat adalah Siswa-siswi SD Sarawati 6 Denpasar memahami makna dari canang sari. Indikator penilaian meliputi memahami pengertian canang sari, memahami fungsi canang sari, menyebutkan bahan-bahan untuk membuat canang sari, membuat canang sari, memahami jenis-jenis sampah, membedakan sampah organik dan non organik, menjelaskan manfaat sampah organik dan non organik. Pada kegiatan kegidua, siswa-siswi SD Saraswati 6 Denpasar mampu memahami dan membuat kompos dari canang sari. Indikator penilaian yaitu mampu menyebutkan alat dan bahan pembuatan kompos dari canang sari, melaksanakan pembuatan kompos dari canang sari, menganalisis keadaan kompos pada saat pembuatan, dan mempresentasikan cara membuat kompos dari canang sari. Training on Making Compost from Canang Sari Offerings At SD Saraswati 6, Denpasar, BaliCanang sari is symbolic of the presence of Ida Sang Hyang Widhi. Before starting learning activities, schools in Bali always offer canang sari at the tample. Canang sari becomes garbage when it has finished being used in prayer activities at school. The purpose of this community service is that students are able to carry out the canang sari cycle. The implementation of the service was carried out for 4 months with the stages of observation, preparation and design of activities, implementation of activities, and evaluation. The results of community service activities are students of SD Sarawati 6 Denpasar understand the meaning of canang sari. Assessment indicators include understanding the meaning of canang sari, understanding the function of canang sari, mentioning the ingredients for making canang sari, making canang sari, understanding the types of waste, distinguishing organic and non-organic waste, explaining the benefits of organic and non-organic waste. In the second activity, students of SD Saraswati 6 Denpasar were able to understand and make compost from canang sari. The assessment indicators are being able to mention the tools and materials for making compost from canang sari, carry out the making of compost from canang sari, analyze the state of compost at the time of making, and present how to make compost from canang sari.

Abstract

This study is motivated by the high concentration of nutrients, particularly ammonium (NH₄⁺) and phosphate (PO₄³⁻), in domestic wastewater, which can lead to eutrophication if not properly treated. The objective of this research is to analyze the hydraulic characteristics and filtration performance of biochar media in a two-compartment filtration system for domestic wastewater treatment. The study was conducted experimentally using a laboratory-scale filtration unit with effective dimensions of 200 mm × 200 mm and a media height of 700 mm. The system was operated under continuous flow conditions at a discharge rate of 50 L/h for 3 hours per day. The analyzed parameters included filtration effectiveness duration, bed volume (BV), head loss, permeability coefficient (K), and hydraulic retention time (HRT), as well as the removal efficiency of ammonium and phosphate, measured using spectrophotometric methods. The results showed that the filtration effectiveness duration reached 28.17 hours, with a total treated water volume of 1.4083 m³, equivalent to 66.45 BV. The head loss value of 0.50 m remained relatively stable throughout the operation, indicating no significant clogging of the media. The permeability coefficient of 3.12 × 10⁻⁴ m/s indicates moderate to high permeability, with an HRT ranging from 21 to 25 minutes. The biochar media achieved ammonium removal efficiencies of 65–75% and significantly reduced phosphate concentrations, with the highest efficiency observed at the initial stage before declining due to media saturation.
