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.

Abstract

Digitalization of education is a logical consequence of developments over time, a response to educational services that are experiencing changes in both the learning system and learning culture. Developments in the field of education are closely related to the term innovation. Innovation in the realm of education is an obligation for all educational actors. Moreover, the development of science and technology is growing rapidly. The parenting pattern that has been implemented in most vocational schools within the Ministry of Transportation is still more of a manual system that cannot be connected directly to digitalization. The aim of the process of developing digitalization of parenting patterns is expected to increase efficiency and optimization in many ways, including efficiency and optimization of parenting activities, connectivity between institutions or units involved in parenting, access to data related to parenting patterns, personal data of cadets and caregivers, as well as ease of use. information in accessing rules relating to parenting patterns. The research method used is a mixed type of research. Mixed research is the use of two types of research, namely qualitative and quantitative in one study. The research location is planned to be carried out at a vocational school under the Ministry of Transportation (Poltekpel Sorong). This research then produced an online-based digitalization development desktop software and was then named the see cadet application website. This development and research uses the ADDIE Development Model, namely the analysis stage, design stage, development stage, implementation stage and evaluation stage.

Abstract

Mining has been a practice spanning millennia, leaving behind a legacy of mine waste containing hazardous substances, including various metals in nearly every country. Indonesia is one of the most nickel-rich regions in the world. Some of these resources are located in the Sulawesi and North Maluku regions. Sulawesi includes Central Sulawesi, South Sulawesi and Southeast Sulawesi. Pollutants in the form of mercury metal (Hg), lead metal (Pb), cadmium metal (Cd), and chromium metal (Cr) are considered toxic and difficult to remove due to their stable nature. Effective remediation methods are imperative in response to this issue, among which bioremediation and phytoremediation stand out. Bioremediation employs microorganisms to detoxify the environment of heavy metals, while phytoremediation utilizes plants for the same purpose. Both methods involve intricate interactions among plants, microbes, and their substrates to purify the environment and facilitate further filtration. Bioremediation encompasses two primary approaches: the in-situ method and the ex-situ method. In situ methods include bioventing, biosparging, bioaugmentation, and biostimulation. Ex-situ methods, contaminated soil or water is retrieved from its origin and purified elsewhere by living organisms; this process utilizes bioreactors, aeration, steam regulation, and additional nutrients to increase the rate of pollutant decomposition. The bioremediation mechanism involving microorganisms employs biosorption, bioaccumulation, biotransformation, and bioleaching. Phytoremediation employs several methods, including phytoextraction, phytofiltration, phytovolatilization, phytodegradation, and phytodesalination. Identifying efficient hyperaccumulators is the most direct approach for successful heavy metal phytoremediation. Bioremediation and phytoremediation techniques are economical and suitable solutions to address heavy metal pollution in polluted environments. With a deeper understanding of these techniques, it is hoped that we can more effectively address these complex environmental challenges, particularly in mining areas in Sulawesi, Indonesia.
