<![CDATA[Program pengabdian ini bertujuan untuk meningkatkan kualitas sanitasi dan mencegah kasus diare di Pondok Pesantren Daru Muhyiddin NW Santong Terara Lombok Timur melalui pelatihan teknologi pengolahan air bersih. Masalah utama yang dihadapi adalah buruknya sanitasi dan tingginya prevalensi diare akibat pembuangan sampah sembarangan serta pengelolaan air yang tidak optimal. Untuk mengatasi masalah ini, program memperkenalkan metode slow sand filter dan biomassa filter berbahan arang aktif dari tempurung kelapa. Pelatihan dilakukan melalui beberapa tahapan: (1) Pemberian materi teori yang meliputi pentingnya sanitasi, pengenalan teknologi pengolahan air bersih, dan prinsip kerja slow sand filter serta biomass filter; (2) Praktik langsung pembuatan dan instalasi filter dengan menggunakan bahan lokal, seperti pasir halus, kerikil, dan arang aktif dari tempurung kelapa; dan (3) Evaluasi kinerja filter berdasarkan parameter kualitas air seperti kekeruhan dan total zat padat terlarut (TDS). Proses pemilihan peserta melibatkan 50 santri yang dipilih berdasarkan ketersediaan waktu dan minat untuk terlibat dalam program, dengan fokus pada mereka yang bertanggung jawab atas pengelolaan air di pesantren. Evaluasi peningkatan pengetahuan peserta dilakukan melalui pre-test dan post-test. Hasil evaluasi menunjukkan adanya peningkatan pengetahuan yang signifikan, dengan skor rata-rata meningkat dari 45 pada pre-test menjadi 80 pada post-test (peningkatan 41,67%). Dari segi kualitas air, hasil pengukuran menunjukkan penurunan TDS setelah penggunaan filter. Program ini berhasil mendukung pencapaian Sustainable Development Goals (SDGs) terkait air bersih dan sanitasi, serta memberikan solusi praktis bagi perbaikan sanitasi di pesantren. Empowering Santri of Pondok Pesantren Daru Muhyiddin NW to Improve Sanitation Quality and Prevent Diarrhea Through Slow Sand Filter and Biomass Filter Training Abstract This community service program aims to improve sanitation quality and prevent cases of diarrhea at Pondok Pesantren Daru Muhyiddin NW Santong Terara, East Lombok, through training in clean water treatment technology. The main issues faced are poor sanitation and the high prevalence of diarrhea due to improper waste disposal and suboptimal water management. To address these issues, the program introduced the slow sand filter and biomass filter methods, using activated charcoal from coconut shells. The training was conducted in several stages: (1) Theoretical sessions covering the importance of sanitation, an introduction to clean water treatment technology, and the working principles of the slow sand filter and biomass filter; (2) Hands-on practice in constructing and installing the filters using local materials, such as fine sand, gravel, and activated charcoal from coconut shells; and (3) Evaluation of filter performance based on water quality parameters, such as turbidity and total dissolved solids (TDS). The participant selection process involved 50 students, chosen based on their availability and interest in participating in the program, with a focus on those responsible for water management at the pesantren. Participant knowledge improvement was evaluated through pre-test and post-test assessments. The results showed a significant increase in knowledge, with average scores rising from 45 in the pre-test to 80 in the post-test (an increase of 41.67%). In terms of water quality, measurements indicated a decrease in TDS after using the filters. This program successfully supports the achievement of the Sustainable Development Goals (SDGs) related to clean water and sanitation, while also providing practical solutions to sanitation issues at the pesantren.]]>
