Abstract


As the producer of waste (both in solid form and wastewater), the increase of population creates a dominant effect on environmental problems. Escalation of the amount of domestic wastewater has led to greater sanitation problems. Indonesian government has carried out several programs for improving sanitation access and facilities. Community-based wastewater treatment plant (Communal WWTP) is one of the priority programs. Sleman Regency in Special Province of Yogyakarta owns 131 communal WWTP, where the oldest one had been built in 2006 while the newest one was installed in 2018. In this study, the techno-environmental assessment of communal WWTP in the District of Sleman, Yogyakarta was carried out. Sampling selection of communal WWTPs was undertaken using Stratified Random Sampling techniques. Data collection was executed by a combination of field surveys and in depth-interview of several relevant personnel. The study was done for 30 communal WTTP in various Districts in Sleman regency. Assessment was carried out based on the Likert scale of 4. The results showed that the average score for environment aspect was 2.94 (good), while that for technical aspect was 3.52 (very good). Overall, the techno-environmental score of communal WWTP in Sleman Regency, Yogyakarta was 3.23 out of 4, which was categorized as good.

Sebagai produsen limbah (baik limbah padat maupun air limbah), peningkatan jumlah penduduk berpengaruh dominan terhadap masalah lingkungan. Eskalasi jumlah air limbah domestik berujung pada masalah sanitasi yang semakin besar. Pemerintah Indonesia sudah menjalankan beberapa program untuk meningkatkan fasilitas dan akses sanitasi. Instalasi pengolahan air limbah komunal (IPAL) menjadi salah satu program prioritas. Kabupaten Sleman memiliki 131 IPAL komunal, yang tertua dibangun tahun 2006 dan yang terbaru pada tahun 2018. Dalam penelitian ini, asesmen teknologi lingkungan (techno-environment) dilakukan terhadap IPAL komunal di Kabupaten Sleman, Yogyakarta. Pengumpulan data dikerjakan menggunakan kombinasi metode survei lapangan dan wawancara mendalam dengan pelaku IPAL komunal yang relevan. Pemilihan sampel IPAL komunal dipilih menggunakan teknik Sampling Acak Terstratifikasi (Stratified Random Sampling). Penelitian dilakukan terhadap 30 IPAL Komunal di berbagai Kecamatan di Kabupaten Sleman.  Asesmen dilakukan berdasarkan skala Likert (4). Hasil penelitian menunjukkan bahwa aspek lingkungan memperoleh skor rata-rata 2,94 (baik) dan aspek teknis-teknologis 3,52 (sangat baik). Secara keseluruhan kategori teknologi-lingkungan (techno-environment) dari IPAL Komunal di Kabupaten Sleman Yogyakarta mempunyai skor rata-rata 3,23 dari nilai maksimal 4, dan dikategorikan sebagai baik.
