Abstract

The research aims to (iesign a determination modelfor the locations of ICTbased economic service particularly the ATM (Automatic Teller Machine) service.The initial step of this research was to compile a database of the ATM service useby respondents in JjJekasiCity. The data base covered the locations of the ATMsthe respondents visited and their reasons for choosing those locations. The nextstep was to perform the network and spatial analysis by using Arc View GIS 3.x todetermine the optimal service locations. The research result shows that: 1) Thelocations of ATM placement were mostly found in areas of trade and service,industry and regular residence, 2) The orientation of ATM location developmentrequired by the people was on regular and irregular residence considering theshort distance, 3) In determining optimal ATM locations attention must be paid tothe parameter of distance between the location and trade and service areas as wellas the regular residence. The use of network analysis is indeed helpful indeveloping model of the service location in the determination of optimal servicearea.

Abstract

Penelitian ini bertujuan untuk membandingkan keakuratan hasil identifikasi penggunaan lahan tambak di daerah pesisir Kabupaten Pati Provinsi Jawa Tengah. Dengan memanfaatkan data citra optik (Sentinel-2) dan citra radar (Sentinel-1). Pemetaan dilakukan dengan menerapkan transformasi indeks air berupa NDWI (Normalized Difference Water Index) untuk citra optik dan SDWI (Sentinel-1 Difference Water Index) untuk citra radar serta pengklasifikasian terbimbing dengan metode Random Forest pada masing-masing citra. Hasil penelitian menunjukkan bahwa penggunaan citra optik dalam pemetaan tambak memberikan akurasi yang lebih baik dibandingkan dengan citra radar berdasarkan hasil uji akurasi dengan metode Confusiion Matrix. Dimana hasil menunjukkan pada citra optik Sentinel-2 menghasilkan akurasi sebesar 94.61% dan untuk citra radar Sentinel-1 sebesar 73.21%. Serta penggunaan transformasi indeks air sangat membantu dalam penentuan sampel klasifikasi. Ditemukan pada penelitan bahwa akurasi pada citra radar cukup rendah dibandingkan dengan citra optik dikarenakan sensitivitas pada citra radar terhadap badan air sangat tinggi. Sehingga memungkinkan kesalahan klasifikasi antara laut dan tambak
