KAJIAN RENCANA TATA RUANG WILAYAH BERDASARKAN RISIKO BENCANA GEMPA BUMI DI KOTA JAYAPURA

Abstract

A study has been conducted on the typology of earthquake disaster-prone areas in the city of Jayapura and
the suitability of Regional Spatial Planning (RTRW) for land use capacity in the city of Jayapura. The study on
earthquake disaster-prone area typology aims to determine the distribution of stability levels of the area against
the risk of earthquakes. This study employs a weighting matrix method for area stability based on the Minister of
Public Works Regulation No. 21 of 2007 concerning Guidelines for Spatial Planning of Volcanic Eruption and
Earthquake-Prone Areas (Department of Public Works, 2007). The research results indicate that the final score for
the city of Jayapura is between 30 - 45, which falls into all stability categories: stable and less stable. The
percentage of area for each category is 97.81% for Stable Type A, 1.91% for Stable Type B, and 0.28% for Less
Stable Type C. The typology of earthquake disaster-prone areas in Jayapura based on stability scores falls into
categories A, B, and C.
The study on the suitability of the Regional Spatial Planning (RTRW) for 2013-2033 with the land use
capacity in Jayapura was assessed by scoring data on land capacity and land use, followed by an overlay analysis.
This resulted in a land capacity suitable for development of 57,039.39 hectares, or about 60.48% of the study area,
while approximately 37,272.96 hectares, or around 39.52%, were deemed unsuitable.
