Abstract

Trade and service area is an area that facilitates trade transactions and services between people in need (demand side) and people who sell services (supply-side). In determining trade areas and services, SMCE or Spatial Multi-Criteria Evaluation or spatial evaluation techniques consider many different criteria when making decisions. The method used in this paper is SMCE with Weight Overlay technique using four variables, namely roads, slopes, settlements and rivers. Weighting carried out in the analysis was made with various simulations, namely Simulation A with the same weight weighting on each variable 25%, simulation B with dominant weighting on one of the variables with a composition of 55%:15%:15%:15% and simulation C gave the highest weight to the most influential variables and gave the lowest weight to the variables that were less influential for the Trade and Service Area. In this Simulation, the road network's weight is 30%, settlements are 25%, slopes are 25%, and the rivers are 20%. The total area of 23.5 Km2 or about 8.8% of Serang City area located in the city centre with excellent accessibility, not far from residential areas, a safe distance from the river, and an area with flat marbles.

Abstract

Karangasem Regency Regional Regulation Number 17 of 2012 concerning the RTRW of Karangasem Regency in 2012-2032 is a guide for the Regional Government in preparing the RTRW. This regulation also manages disaster-prone areas (KRB) following the Minister of Energy and Mineral Resources No. 11/2016. In 2017, the Geospatial Information Agency issued a map of the Gunung Agung KRB zone that can be used as a basis for evaluating residential zones that were regulated in the RTRW Regional Regulation. In addition, the conversion of land into a residential zone due to the population growth reached 1980 people/year. This was the reason the existing RTRW needed to be evaluated, given the potential for increased vulnerability due to the emergence of new settlements in the KRB zone. Based on the results of the RTRW evaluation, it was known that residential areas were covering an area of ±566,69 Ha in the KRB II zone and ±160,15 Ha in the KRB III zone which should be a conservation area. Moreover, population growth caused the land conversion of ±992 Ha, where there was an increase in the residential zone in KRB III by ±73,36 Ha which potentially increased the vulnerability of people living in the area.
