Persebaran Habitat Keong Perantara Schistosomiasis di Dataran Tinggi Lindu, Kabupaten Sigi, Sulawesi Tengah

ABSTRACT Schistosomiasis in Indonesia is caused by the trematode worm, Schistosoma japonicum, with the snail Oncomelania hupensis lindoensis as the intermediate host. The presence of these snails is an indicator of determining the habitat area for the intermediate host of schistosomiasis. The aim of the study was to map the distribution of snail habitat in the Lindu endemic area. An observational study with a cross-sectional design was conducted in August 2021. The study was conducted in two villages in the Lindu Highlands, Sigi Regency, Central Sulawesi Province. The number of snail habitats in the Lindu Plateau found 25 habitats, covering an area of ​​27,088 m2. Snail density and infection rate (IR) were found to be 27.06 snails/minute (IR 0.68%). Based on the research, it can be concluded that the distribution pattern of the snail habitat in Lindu was clustered in certain areas. Habitat in Anca Village was most widely found in neglected coffee plantation areas, and a small part in primary forest areas. Snail habitat in Tomado Village was mostly found in watersheds, parapa grass in swamp areas, and uncultivated rice fields. Environmental management that can be carried out by multi sectors are the creating of rice fields, the creation of fish ponds, and the diversion of community paths in the Lore Lindu National Park area that passes through the habitat of schistosomiasis intermediate snails. ABSTRAK Schistosomiasis di Indonesia disebabkan oleh cacing trematoda jenis Schistosoma japonicum dengan hospes perantara keong Oncomelania hupensis lindoensis. Keberadaan keong tersebut sebagai indikator penetapan daerah habitat hospes perantara schistosomiasis. Tujuan penelitian adalah untuk untuk memetakan distribusi habitat keong di wilayah endemis Lindu. Jenis penelitian adalah observasional dengan desain potong lintang yang dilakukan pada bulan Agustus tahun 2021. Penelitian dilakukan di Desa Anca dan Tomado Kecamatan Lindu Kabupaten Sigi, Provinsi Sulawesi Tengah. Jumlah habitat keong di Dataran Tinggi Lindu ditemukan 25 habitat, seluas 27.088 m2. Kepadatan keong dan tingkat infection rate (IR) ditemukan sebesar 27,06 keong/menit (IR 0,68%). Berdasarkan penelitian dapat disimpulkan bahwa pola persebaran habitat keong di Lindu adalah mengelompok/clustered pada daerah tertentu. Habitat di Desa Anca ditemukan paling banyak di daerah kebun kopi yang terabaikan, dan sebagian kecil di daerah hutan primer dengan kanopi tertutup. Habitat keong di Desa Tomado paling banyak ditemukan di daerah aliran air, parapa, rawa, dan sawah tidak diolah. Manajemen lingkungan yang dapat dilakukan oleh lintas sektor yaitu pencetakan sawah, pembuatan kolam ikan, dan pengalihan jalur masyarakat dalam Kawasan Taman Nasional Lore Lindu yang melewati habitat keong perantara schistosomiasis.
