Abstract

Payakumbuh City is one of the cities located in West Sumatra Province, with a population of 149,077 people. Public transportation is needed for daily mobility, especially for students, because public transportation in this city only consists of 21 units and only serves one route. This study aims to establish service zones, routes, stops or bus stops, and bus transportation modes that are suitable for the geographical conditions of Payakumbuh City. The method used in this study is Graph Neural Network (GNN) with the variables analyzed being the distribution of schools, traffic congestion points, points of interest, and road networks. The results of the study show that service zones can be determined based on the existing land use in Payakumbuh City, dividing the service zones into 4 zones with a total route length of 93.54 kilometers, 209 bus stops, and a suitable mode of transportation, namely microbuses with two types of buses, with an estimated number of 211 units. Payakumbuh City can implement public transportation, particularly school buses, but special attention must be given to the existing road conditions, as the road width in the area is 4-7 meters. Therefore, in its implementation, three service zones can use microbuses with a capacity of 30 passengers, and one service zone can use microbuses with a capacity of 20 passengers.

Abstract

Fishing communities are coastal communities that are highly dependent on marine conditions in carrying out fishing activities. The dynamics of oceanographic conditions, such as ocean currents and tidal fluctuations, play an important role in determining fish distribution, fishing safety, and the success of fishing activities. This study aims to examine the effect of oceanographic factors on the catch of fishing communities in Namosain Village, Alak District, Kupang City. This research employed a quantitative approach using a survey method. The research population consisted of fishermen in Namosain Village, with the sample determined using the Slovin formula. The results showed that partially, ocean currents had a significant effect on fishermen’s catch, while tidal fluctuations did not have a significant effect on fishermen’s catch. However, simultaneously, oceanographic factors had a significant effect on the catch of fishing communities in Namosain Village. These findings indicate that oceanographic conditions play an important role in determining the success of fishing activities; therefore, adaptation efforts and increased fishermen’s understanding of marine dynamics are needed to support the sustainability of capture fisheries and improve the welfare of coastal fishing communities.

Abstract

Banjir merupakan bencana hidrometeorologi yang paling sering terjadi di Indonesia, termasuk di Sub-DAS Batang Tebo yang mencatat 30 kejadian banjir selama periode 2019–2024. Penelitian ini bertujuan memetakan bahaya banjir di Sub-DAS Batang Tebo menggunakan metode Geomorphic Flood Index (GFI) berbasis data Digital Elevation Model (DEM), serta menguji akurasi model terhadap data genangan aktual dari citra Sentinel-1 yang diolah melalui Google Earth Engine (GEE). GFI dihitung secara sistematis menggunakan dua parameter utama, yaitu Height Above Nearest Drainage (H) dan Hydraulic Radius Proxy (hr). Hasil pemodelan menunjukkan bahwa kelas bahaya rendah mendominasi wilayah seluas 279.080,56 ha (65,4%), diikuti kelas sedang 90.913,56 ha (21,3%), tinggi 31.186,86 ha (7,3%), dan sangat tinggi 25.561,28 ha (6,0%). Lima kecamatan termasuk kelas bahaya sangat tinggi: Kecamatan Tebo Tengah, Kecamatan Batin II Babeko, Kecamatan Bungo Dani, Kecamatan Pasar Muaro Bungo, dan Kecamatan Bathin III. Uji akurasi menggunakan True Positive Rate (TPR) menghasilkan nilai 0,64 pada base case (GFI 2,3), sedangkan Frequency Ratio (FR) meningkat konsisten dari 0,11 pada kelas rendah hingga 7,23 pada kelas sangat tinggi. Hasil ini menunjukkan bahwa metode GFI layak digunakan sebagai pendekatan awal pemetaan bahaya banjir berbasis geomorfologi.

Abstract

This study aims to analyze the effect of the Snowball Throwing learning model on the cognitive learning outcomes of Geography students of class X IPS on the Basic Knowledge of Geography material at SMA Negeri 1 Randangan. The study used a quantitative approach with a quasi-experimental design of the pretest-posttest control group type. The experimental class followed the Snowball Throwing learning model, while the control class used lectures and questions and answers. The results showed that the improvement in learning outcomes in the experimental class was better than the control class. The N-Gain value of the experimental class was in the high category, while the control class was in the medium category. This difference indicates that learning that provides space for students to formulate questions, discuss, and answer friends' questions is able to strengthen conceptual understanding better than one-way learning. These findings confirm that Snowball Throwing not only improves learning outcomes, but also encourages activeness, academic communication, and student involvement in the geography learning process. Thus, this model can be considered as an alternative learning method for Geography material that requires conceptual understanding, interrelationships between phenomena, and more active reasoning.

Abstract

Industrialization, as part of economic development, drives the transformation of a region from an agrarian to an industrial one, but also creates complex social and environmental problems. Changes in livelihoods, the emergence of social disparities, and the decline in environmental quality indicate that communities need to adapt to survive. This study aims to analyze the forms of community adaptation to the social and environmental impacts of industrialization in Dawuan Tengah Village, Cikampek District, Karawang Regency. The method used is descriptive qualitative with data collection techniques through in-depth interviews and field observations. Informants were determined purposively based on certain criteria and data were analyzed through stages of transcription, coding, categorization, and drawing conclusions. The results show that industrialization has a positive impact in the form of increased employment opportunities, income, and the development of local economic enterprises. However, industrialization also has negative impacts in the form of changes in social interaction patterns to become more individualistic, air pollution due to industrial activities and logistics vehicles, noise, congestion, and changes in land use. These conditions indicate pressure on the quality and sustainability of the community's residential environment. The community adapts through job diversification, lifestyle changes, and increased environmental awareness. Thus, industrialization has a multidimensional impact, so sustainable management is needed to create a balance between economic growth and the quality of life of the community.

Abstract

Limited integration between petrographic data and interpretations of geological evolution in the Buay Pemaca area and its surroundings has resulted in an incomplete understanding of tectonic controls and regional geological development. This study aims to analyze rock characteristics using a petrographic approach and to examine its implications for the geological history of the study area. The methods employed include macroscopic and microscopic analyses to identify mineral composition, texture, and grain relationships, which are then interpreted within a regional geological framework. The results indicate that the rock variations in the study area record stages of geological evolution controlled by the interaction of magmatic, tectonic, and sedimentary processes. The initial phase is associated with subduction activity that produced volcanic rocks and intrusions, followed by the development of a sedimentary environment transitioning from terrestrial to shallow marine conditions due to transgression and regression mechanisms, and culminating in volcanic activity that again influenced the geological system. This study confirms that rock characteristics are closely related to ongoing regional tectonic dynamics. Thus, the geological evolution of the study area is controlled by repeated interactions between endogenous and exogenous processes that systematically form the rock sequence. The main contribution of this study is the integration of petrographic analysis with a more comprehensive interpretation of geological evolution.
