Abstract

Flooding is one of the environmental problems that often occur in Medan City due to rapid urban development and land use change. This research aims to analyse the spatial distribution of flood vulnerability in Medan City based on the parameters of land use, slope, soil type, geology, distance from river and rainfall. The methods used in this research include Geographic Information System (GIS) analysis and weighting of flood vulnerability parameters using the scoring method. The data used included Sentinel 2 imagery for land use, DEM data for slope, CHRIPS for rainfall and SHP data for soil type and geology. The spatial distribution of flood vulnerability in Medan City shows a concentration in the southwest and central parts of the city. The spatial distribution of flood vulnerability is mostly at the high - very high vulnerability level, namely in the Belawan Sicanang area of 1,047.07 ha. high vulnerability level, namely in the Belawan Sicanang area of 1,047. 07 ha with a percentage of 12%, Martubung village area of 1,032 ha with a percentage of 11%, Kelurahan Besar area of 1,013 ha with a percentage of 11% and Pekan Labuhan village area of 1,022 ha with a percentage of 11%. Ha with a percentage of 11%. This research is expected to be a suggestion for spatial distribution developed as an early warning system for flood impacts in Medan City.

Abstract

The increase in waste generation and the lack of waste management efforts in landfills (TPA) continuously causes the capacity of the landfill to be full. Determination of the location of a new landfill designation is one solution to avoid environmental pollution problems. The purpose of this study is to determine the location of the waste landfill feasible zone based on regional criteria and determine the location of alternative waste landfill designations based on the exclusion criteria in Bathin Solapan District. This research uses primary data and secondary data. The research method used is descriptive research with a quantitative approach. In this research, the location of waste landfill is determined by adjusting SNI 19-3241-1994 and analyzed by overlay analysis and scoring. The samples in this study were several locations determined from the results of overlaying several land unit maps. Sampling was done by purposive sampling. The results showed that there was a waste landfill feasibility zone in Bathin Solapan District covering an area of 21,831.1 Ha spread across 13 villages. The alternative location of the waste landfill designation based on the elimination criteria is located in Petani Village, Jalan Rangau km 17 with a land area of 9.16 Ha and a suitability value of 664. Based on the opt-out stage analysis, the selected alternative site has a more positive socio-economic impact compared to the other sites.
