Abstract

The research describe about surface water ecosystem study in Merauke Papua by using multisource and multistage remote sensing data which was splitted into two parts based on the study areas. First, it is for micro scale spatial analysis focusing on the Rawa Biru – Torasi watershed, while the second is for macro scale spatial analysis for Transfly ecoregionin the floodplain areas of Merauke. Multispectral approach was adopted for Landsat image analysis, followed by field survey on the selected areas. Auxilary data used are maps, secondary documents in order to improve understanding of the areas. Interview and discussion with related institutions (Wasur National Sanctuary, Potable Water Services, Internal Affairs Government, Forestry Service) accordingly were carried out. The research result showed that remote sensing imagery are usefull for surface water resources study. Physical condition of the Rawa Biru – Torasi watershed, vegetation analysis by using multitemporal data, wetland type, hydrological process in the floodplain were presented. Rawa Biru watershed as a resource for drinking water supply environmentaly decreased considerably due to the species invasion, with successively dominated by hydrophilla, tebu rawa, rumput pisau, dan Mellaleuca and sedimentation took place in the main body of swamp. Upper part of the watershed is actually included in the Papua New Guinea, in long water resources development scheme, it need administratively belong to one recharge areas for the watershed.

Abstract

Sejak tahun 2013 hingga tahun 2017 serangan penyakit demam berdarah (DBD) di Kota Baubau terus mengalami peningkatan jumlah angka kesakitan. Laporan Dinas Kesehatan Propinsi Sulawesi Tenggara Tahun 2018 menunjukan fakta bahwa Baubau merupakan kota dengan angka kejadian DBD tertinggi ketiga dari 17 kabupaten/kota lainnya. Pemetaan distribusi tingkat kerentanan wilayah terhadap penyakit DBD merupakan langkah penting dalam mendukung penyusunan strategi penanganan penyakit DBD. Penelitian ini bertujuan memetakan dan mendeskripsikan distribusi tingkat kerentanan lokasi penelitian. Kota Baubau sebagai lokasi penelitian dengan mengambil populasi sebanyak 129 kasus kejadian sepanjang tahun 2015 hingga Februari 2016. Dalam penelitian ini, kami mensimulasikan distribusi kerentanan wilayah terhadap penyakit demam berdarah pada resolusi spasial 30x30 meter. Model dibuat menggunakan dua algoritma machine learning yang cukup kuat dan umum digunakan mencakup support vector machine (SVM) dan random forest (RF) dengan melibatkan sejumlah variabel seperti penggunaan/tutupan lahan, NDVI, BLFEI, LST, curah hujan dan kelembapan tahunan yang diturunkan dari citra Landsat 8 OLI/TIRS dan data iklim BMKG serta BWS. Kemampuan model dinilai menggunakan kurva area under curve-receiver operating characteristic (AUC-ROC). Hasil penelitian menunjukan Kecamatan Batupuaro dan Murhum merupakan kecamatan yang wilayah administrasinya didominasi oleh zona rentan sebesar 92,54% dan 41, 74% dari luas total wilayah masing-masing
