Abstract

Coal mining has a significant impact on reducing river water quality. The decline in river water quality causes problems for human life and the environment. Therefore, this research aimed to evaluate river water quality and develop strategies for improving river water quality due to open pit coal mining activities in Tenggarong Seberang District and develop environmental improvement strategies. Several chemical parameters, including pH, TSS, Fe, and Mn, were observed through laboratory tests to determine water quality in the Separi River used in coal mining. The next step was determining environmental improvement strategies using the ISM approach. Twenty stakeholders from related agencies and institutions using FGD were involved in developing a policy strategy. The results of the analysis showed that there has been a decrease in river water quality standards due to mining activities in the research area, and the quality is still below the standard quality. Therefore, two significant strategies must be a priority for the environmental management of the Separi River. First, Conducting an environmental audit of the factors causing the decline in river water quality is necessary. Second, there must be warnings and legal sanctions for negligence in oil spills and oil used from coal mining.

Abstract

One of the most common natural disasters in Indonesia is landslides Heavy rains have caused several landslides in various regions, causing a large impact every year. Landslides caused by rainfall have also become a global problem in many regions, leading to large-scale landslides. Landslides that occur in Sitinjau Lauik, Padang City are influenced by high rainfall with very steep slopes (70˚-80˚), making this area very prone to landslides. One of the techniques used in mapping landslide vulnerability is the Unmanned Aerial Vehicle (UAV) technique, which is a flying machine controlled by a remote controller. The data obtained will be processed using ArcGIS with Weighted Overlay technique, and factors affecting landslides have been conditioned based on Multi Influencing Factor (MIF). This research aims to achieve: 1) the landslide vulnerability level of Sitinjau Lauik Padang-Solok, 2) determine the landslide prone zones in Sitinjau Lauik. The type of research used in this research is quantitative research with spatial approach. The data required are primary data and secondary data. Primary data consists of aerial photographs taken using drones and processed to produce slope, elevation, aspect, and TWI. The secondary data used is the Landsat 8 image in 2023 which is used to determine the vegetation index. This research resulted in 1) The landslide vulnerability level of Sitinjau Lauik is divided into four classes, namely, low landslide vulnerability level with an area of 4342m or 10.81%. Medium landslide vulnerability level with an area of 24575m or 61.16%. High landslide vulnerability level with an area of 11,294m or 28%. And very high landslide vulnerability level with an area of 14m or 0.03%. 2) Landslide vulnerability zonation based on slope condition is divided into 3 zones: Zone A with an area of 20,901m, Zone B with an area of 4642m. And Zone C with an area of 14,614m.

Abstract

Rock is a solid substance that contains minerals and is formed naturally. Joint is a fractured plane without a shift in the rock body and can be present systematically formed by tectonic forces and can be analyzed as an interpretation of its forming tectonic forces from systematic data. This research was conducted in Sugai Cibogo, Padalarang, West Bandung Regency, with coordinates 06049'29.07 " S and 107026'17,69 "S. This type of research used in research is a quantitative descriptive study by telling the conditions of the field conditions as is. The purpose of this study was to determine the direction of rock fractures in the Cibogo Padalarang river and how to take samples in the Cibogo Padalang river. The results of this study found that the fracture that occurred was a normal fault because sigma 1 was bigger than the other sigma and the sample was taken using a geoglogic hammer, compass, meter by determining the age of rocks and others.

Abstract

Coral reefs are known as complex and productive shallow tropical marine ecosystems. They serve as a habitat for various species of marine plants, marine animals, and marine microorganisms. The deterioration of coral reefs threatens the survival of this shallow marine ecosystem. Mapping the distribution of coral reefs using remote sensing technology is a crucial instrument in the effort to monitor and protect coral reefs while preserving the marine environment. This research aims to map and measure the extent of coral reefs in the Pieh Islands Marine Conservation Area in 2022. In this study, we used Sentinel-2 imagery from 2022 and applied the Object-Based Image Analysis (OBIA) method to detect the extent of coral reefs. Sentinel-2 imagery was processed using ArcGIS and eCognition software, involving atmospheric correction, image clipping, image compositing, segmentation, image classification, and accuracy testing. The data processing results indicate that coral reefs are distributed around the waters of Pieh Islands, with the highest density located to the south of Pieh Islands's waters. The total extent of detected coral reefs in this study is 15.76 hectares. The use of Sentinel-2 imagery with the OBIA method has proven to be effective in detecting the extent of coral reefs in the Pieh Islands Marine Conservation Area.

Abstract

The city of Padang is one of the areas that has a high level of vulnerability to tsunami disasters. People can anticipate tsunamis, one of which is by building houses in a tsunami safe zone, but before many people do this anticipation, it is best to test the habitability of the settlement. The aim of this research is to find out habitable settlements in the tsunami safe zone of Padang City. This research uses a quantitative descriptive method by utilizing the Geographic Information System through a weighting and scoring method for each indicator. The results of the analysis show that there are 5 classes of vulnerability with a very low level of vulnerability dominating 43,089 Ha or 64.62%, in settlements in accordance with the Padang City Regional Spatial Plan, counting 11 sub-districts with livable settlements in accordance with the results obtained through weight calculations and scoring in each indicator is 2,635 Ha or around 23.87% of the total settlements in the Padang City Regional Spatial Planning Plan.
