Abstract

Land cover change is a major problem with environmental sustainability. The impact of the increasing population is urgent for the need for land for human activities. The purpose of this study is to determine the magnitude of land cover changes that occur in Sinjai Regency for the period 2014 to 2022. The research uses quantitative research. That is research that starts from a specific plan or a detailed set of questions or hypotheses. This research is closely related to the process of enumerative induction (induction based on calculations). Based on the analysis using imagery data, the rate of land change in Sinjai district was obtained as follows: : land cover in the form of mixed land decreased by 287.61 Ha, secondary forest decreased by 135.98 Ha, primary forest by 20.04 Ha, water body by 140.46 Ha and other uses increased by 586.53 Ha. Keywords: rate of change, land cover, temporal

Abstract

Inorganic and organic components, including various dangerous heavy metals such as iron (Fe), can cause water pollution, which is detrimental to the body of organisms because they are toxic. Biosorbent is one of the methods that can reduce the level of iron content in dug well water by using activated charcoal from coconut shells as a filter. This study aimed to determine the pH value, temperature and decrease in Fe levels in dug well water using coconut shell activated charcoal as a biosorbent with time variations of 7 (P1), 14 (P2) and 21 (P3) days. This research is quasi-experimental with a pre-and post-test design with two measurements. Data from laboratory examinations were processed and analyzed using descriptive statistical tests. The results showed that dug well water's pH, temperature, and iron (Fe) level before filtering were 8.71, 31.670C, and 1.87 ml/L. After filtering using active coconut shell charcoal media as a biosorbent, pH values varied from 8, 50 (P1), 8.32 (P2) and 7.69 (P3). The temperature values remain unchanged at 31 degrees with 31.560C (P1), 31.670C (P2) and 31.440C (P3). Levels of iron (Fe) showed a significant decrease from 1.82 mg/L (5%) in P1, 1.20 mg/l (67%) in P2 and 1.11 (76%) in P3. In conclusion, the iron (Fe) content decrease in dug well water has the highest value on the 21st day, with a 76% reduction.  Keywords: active charcoal, Biosorbent, Fe Level, dug well water, Tallo District, Makassar.

Abstract

Land cover change is a transition process, such as agricultural land does not immediately turn into built-up land but into grass/soil or shrubs land cover change the transition process of land cover change. This study aims to (1) Determine the rate of change in the temporal function of the hedge. (2) Determine the value of the protection coefficient based on the results of satellite imagery analysis. The method used in this study is spatial descriptive, with land units as units of analysis or mapping units. In spatial description, the results of the study will be described and displayed in the form of a map. In this study, it will be described spatially and temporally the land cover and its effect on the index of protected function of the research area (Sinjai Regency Watershed). The analysis used is spatial analysis whose processing uses a Geographic Information System, with outputs including Land Use Maps and Land Cover Maps. In the period 2014 - 2022, there was a dynamic change in land cover in the Sinjai Regency watershed. The largest land cover that has changed is miscellaneous use which changed 49.87%, then mixed land which changed 24.66% and water body 12.20%. The index of the protected function of the Sinjai Regency Watershed in 2014 was 0.57 and in 2022 it was 0.50. During the period 2014-2022 there was an increase in the hedging function index by 0.02.
