Why should be in Kulon Progo?

Based on my research, the potential for dumping site in Kulon Progo with a population of 434,483 people is estimated to be up to 173 tons per day or 63,260 tons per year. Meanwhile, the waste handled at the Banyuroto TPA in Kulon Progo is currently based on weighing data as much as 24-35 tons per day.

Reporting from harianmerapi.com (October 2021), "The condition of the Banyuroto TPA as of September 2021 has occurred. The location is indeed far from settlements and not densely populated. But if in the future the population is increasingly dense and around the TPA has become urban, this will become serious problem."

This is why I choose Kulonprogo to be the area of site selection.

Methodology

Buffer & Tessellation

The data used in this project are roads, city, land use, settlements, and rivers. The weighting for each input variable is based on the table 1 (Buffer zone layer with sub-criteria ratings). I use generate tessellation tool for producing the tessellation in hexagon shapes from the weighting result which have been done before in each variable. Analysis using vector approach with generate tessellation tools is available in ArcGIS Pro. The map result can be seen in the All Layer Maps section in GEO MAPID. The steps of generate tessellation are based on literature (Alkaradaghi et al. 2019).

Results

As shown in the image above (Figure 5 & 6), each hexagon has its values based on the weighting results and Total_Value calculations done previously. The higher the Total_Value, the redder the color will appear. The redder the color, the more it shows that the area in the hexagon area is less suitable for use as a dumping site area. On the other hand, the lower the value, which is indicated by a more
