Analysis of Land Suitability Based on Area Functions in the Merawu Watershed, Banjarnegara Regency

Abstract

The decline in the quality of land and the environment is closely related to the increase in changes in land use to settlements as well as to agricultural land that is not in accordance with the spatial layout and function of an area. The purpose of this study is to analyze the suitability of land spatial plans based on the function of the area and analyze the suitability of land use to the function of the area. The method used is the scoring method by assigning a value to the nature of the parameters used in the analysis. The analysis used is Overlay where, the three maps that have been obtained using predetermined criteria are overlapped (overlay), so that the score value of the land unit map is then classified into areas with certain functions. Based on the results of the analysis, the watershed has 3 directions for the function of the area, namely the direction of the protected area function having an area of 17,876.01 ha, the buffer area having an area of 4,599.92 ha and the area for cultivation of seasonal crops and settlements having an area of 839.70 ha.

Heavy metal pollution in the aquatic environment: efficient and low-cost removal approaches to eliminate their toxicity: a review

“…In recent years, numerous studies have been conducted which have successfully examined the removal of heavy metals and organic pollutants that coexist in wastewater. [76][77][78] The selection of an appropriate treatment method depends on a variety of factors, including the economic and environmental impacts associated with the method. Therefore, it is important to carefully evaluate and select the most appropriate combination of removal technologies for each specic situation to achieve efficient and effective removal of heavy metals and organic pollutants from wastewater.…”

Conservation Zone Delimitation Based on Physical Properties in Langsa Watershed, Aceh Province

“…As such, this present study serves as a reference for further investigations on watershed conservation. According to Funan et al (2022) and Wang et al (2022), the Langsa watershed zoning map is very important as a follow-up to control land suitability for the three zones. Indarto (2020) identified that the importance of the watershed position as a comprehensive planning unit is the basic requirement for maintaining a balance when using forest, land, and water resources.…”
