Akses terhadap air bersih tetap menjadi tantangan bagi institusi pendidikan tinggi. Biosand Filter (BSF), sebagai Teknologi Tepat Guna, dapat meningkatkan kualitas air dan berfungsi sebagai alat pembelajaran praktis. Studi ini mengevaluasi dampak intervensi pendidikan partisipatif (paparan teoritis ditambah perakitan BSF secara praktis) terhadap pengetahuan mahasiswa dan indikator organoleptik air yang difilter. Lokakarya pendidikan partisipatif dilaksanakan di Fakultas Kesehatan Masyarakat, Universitas Sriwijaya. Semua mahasiswa angkatan 2023 Program Studi Kesehatan Masyarakat yang mengikuti lokakarya dimasukkan melalui total sampling (n = 100). Prosedur meliputi tes pra-intervensi, sesi teoritis, demonstrasi, perakitan praktis BSF, dan tes pasca-intervensi. Sampel air yang difilter dievaluasi secara organoleptik dan melalui pengamatan visual. Perubahan pengetahuan dianalisis menggunakan uji Wilcoxon signed-rank. Skor pra-tes rata-rata adalah 98,3 dan meningkat menjadi 99,6 pasca-intervensi (mean different = 1,3). Uji Wilcoxon menunjukkan peningkatan pengetahuan yang signifikan (p < 0,001). Penilaian organoleptik dan visual melaporkan penurunan kekeruhan dan tidak adanya bau tidak sedap pada sampel yang difilter, menunjukkan peningkatan kualitas air yang dirasakan. Pendidikan partisipatif berbasis BSF secara signifikan meningkatkan pengetahuan siswa dan terkait dengan sifat organoleptik yang lebih baik pada air yang difilter, mendukung pelatihan praktis dan potensi BSF untuk solusi air di kampus.
