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.

Abstract

This article aims to improve the ability of teachers and students to make media maps arise and improve teacher understanding and ability in terms of understanding pedagogical aspects that can be seen from the process of designing a Learning Implementation Plan (LIP) especially in terms of choosing a model or learning method. This activity was held at SMAN 2 using training methods, question and answer, and practice. In accordance with the objectives of the implementation of the activity, it is expected that teachers and students have an increased ability in terms of mastery to make map media arise. Then the teacher can also improve the teacher's understanding/ability in terms of understanding pedagogical aspects that can be seen from the process of designing the LIP especially in terms of choosing a learning model.

Abstract

Indonesia is an agricultural country and one of the world's rice-producing countries. However, the increase in population has pushed for the conversion of agricultural land to non-agricultural purposes. Solok is a district with the largest paddy field area in West Sumatra. Yet, the increase in population has resulted in a decrease in paddy fields every year. This study aimed to determine the model for changing the area of paddy fields for the 2000-2020 period and determine the direction of sustainable agricultural policies. In defining the paddy field change model, this research uses the input data from the interpretation of 2000 Landsat 5 imagery, 2010 Landsat 7 imagery, and 2020 Landsat Oli 8 imagery. The data were analyzed using a geographic information system (GIS). This research employed the Powersim Software with a system dynamics approach in projecting rice production and demand. This research used Interpretative Structural Modeling (ISM) analysis to determine the direction of sustainable food policy. The results showed that there had been a conversion of 13,801.6 hectares of paddy agricultural land into a built-up area in the 2000-2020 period in Solok District. In 2020, Solok District supplied 2,838 thousand tons of rice, while the demand for rice was 446.3 thousand tons. In the direction of the sustainable agriculture policy, there are three key sub-elements; tightening land use permits, establishing and implementing spatial planning regulations, and consistency in enforcing spatial planning violation laws.

Abstract

Toll road development is a major driver of land use transformation, especially in rapidly urbanizing regions such as Southeast Asia, China, and Sub-Saharan Africa. However, evidence linking toll roads to land conversion, environmental degradation, and economic change remains fragmented and is largely based on observational and cross-sectional studies, limiting causal interpretation. This systematic review synthesizes empirical findings on land use change, environmental and economic impacts, and implications for sustainable corridor planning. Following PRISMA 2020, a Scopus search (2017–2026) identified 1,086 records, with 50 studies included after screening. Results show that toll roads accelerate the conversion of agricultural land into urban and industrial uses, with conversion rates reaching 47.8% in Indonesia. Ecosystem service values decline by 8–23% within 5 km of new expressways. Economic impacts vary, with Chinese studies showing improved land-use efficiency, while African and Southeast Asian contexts reveal increased spatial inequality. A major finding of this review is that the current evidence base remains insufficient to establish strong causal relationships between toll road development and observed environmental-economic outcomes due to the dominance of cross-sectional and non-experimental study designs. This review proposes the Corridor-Mediated Land Transformation (CMLT) framework and recommends stricter land regulation within 5 km of toll interchanges. Future research should apply longitudinal quasi-experimental designs to clarify causal relationships and strengthen policy relevance.
