Abstract

Penelitian ini bertujuan guna untuk mengetahui berapa perkiraan besaran erosi dan sedimentasi total yang terjadi di Batang Palangai dalam waktu satu tahun. Sehingga nantinya besaran erosi dan sedimentasi akan didapatkan setelah dilakukannya sejumlah analisis dengan metode tertentu. Dalam Penyusunan penelitian ini menggunakan metode deskriptif dengan pendekatan kualitatif. Yakni memanfaatkan rumus yang di kembangkan oleh Smith dan Wischmeier( 1978) yang lebih dikenal dengan sebagai Universal Soil Loss Equation( USLE). Sementara guna untuk mencari erosi total dalam satu tahun peneliti menggunakan rumus SCS. Dengan memanfaatkan kedua rumus ini maka peneliti bisa mencari dan mengetahui sedimentasi total dalam satu tahun. Adapun hasil dari penelitian ini setelah dilakukan nya perhitungan dan analisis dengan metode dan pendekatan maka didapatkan nilai total erosi dalam satu tahun ton/ ha/ tahun, dengan besaran sedimentasi dalam satu tahun adalah ton th. Dan jika dicocokkan dengan klasifikasi bahaya erosi yang dikeluarkan oleh kementrian kehutanan pada 1998 lalu, maka daerah ini tergolong kedalam kelas V yang berarti sangat berat dengan besaran erosi 400 ton ha th. Kata Kunci Erosi, Sedimentasi, USLE, Batang Palangai

Abstract

This study conducted an integrated spatial assessment to identify and map erosion and landslide threats, determining high-risk degraded areas in Solok Regency. The methods combined the Universal Soil Loss Equation (USLE) and the Analytic Hierarchy Process (AHP) within a Geographic Information System (GIS) framework. The analysis revealed a critical disconnect between erosion and landslide risks. Although 52.1% of the total area (?101,500 ha) was classified as safe from erosion (EHI<1), a substantial portion of this “safe” land-39.4% and 6.94% of the total area, respectively, exhibited moderate to high landslide susceptibility. Conversely, within the 37.1% of the area unsafe from erosion (EHI>1), moderate and high landslide susceptibility covered 24.3% and 7.4% of the total area, respectively. These results demonstrated that landslide triggers are independent of surface erosion processes in many areas, often occurring in locations considered "safe" from erosion due to innate geological and geomorphological factors. This complex interplay necessitates distinct yet coordinated mitigation strategies. The findings provide crucial spatial data for safe land use planning and disaster mitigation in Solok Regency, with a methodology applicable to other vulnerable landscapes, such as post-mining areas.

Abstract

This study aims to improve student learning outcomes and activeness in Integrated Social Sciences (IPS) learning through the implementation of the Student Team Achievement Division (STAD) cooperative learning model in class VIII of SMP Negeri 57 Muaro Jambi. The research method used Classroom Action Research (CAR). The research subjects were 25 class VIII students in the odd semester of the 2025/2026 academic year. Data were collected through observation, interviews, learning outcome tests, and documentation. The results showed that the implementation of the STAD model significantly improved student learning outcomes, with the average post-test score increasing from 66.52 in cycle I to 90.00 in cycle II. The percentage of learning completeness increased from 43% to 91.3%, while the N-Gain score increased from 0.23 (low category) to 0.67 (medium-high category). In addition, student learning activity and motivation also experienced a significant increase. Students became more active in thinking, dared to express opinions, and showed better cooperation and responsibility in groups. Thus, the application of the STAD type cooperative model has proven effective in improving students' learning outcomes and social interactions in Integrated Social Studies learning at SMP Negeri 57 Muaro Jambi.

Abstract

Flash floods are among the most destructive hydrometeorological hazards in tropical highland regions, yet their spatial risks remain poorly quantified in data-scarce environments. This study assessed flash flood risk in Solok Selatan Regency, West Sumatra (Indonesia), by integrating landform and slope classification with the Topographic Wetness Index (TWI) derived from a 30 m DEM. Historical records of 11 flood events between 2010 and 2020 were used for model validation. The analysis revealed that most of the regency is characterized by moderate flash flood risk, while high-risk zones are concentrated in steep fluvial landscapes. Validation against observed flood locations demonstrated a spatial match of 95.2%, confirming the reliability of the model. In addition, the evaluation of hydrological ecosystem service capacity indicated that over 80% of the landscape has only moderate regulatory function, limiting its ability to buffer runoff. These findings highlight the importance of integrating DEM-based hydrological indices with ecosystem assessments to support more effective disaster risk reduction and spatial planning in tropical highland environments.

Abstract

This research is motivated by the flash flood disaster that occurred in Nagari Limo Kaum, Tanah Datar Regency. This study aims to analyze: 1) Spatial distribution after the flash flood which includes the affected areas and the severity of the impact, as well as accessibility conditions. 2) Post-flash flood disaster management system which includes aspects of preparedness, mitigation, rehabilitation, and recovery. This type of research uses a mixed method that combines quantitative and qualitative. The population includes all jorong in Nagari Limo Kaum, with samples from four affected jorong. Informants were selected using Purposive Sampling. Data were collected through observation, interviews, documentation, and spatial mapping. The results of the study show 1) the distribution of flood impacts is uneven, with the highest level of damage occurring in Jorong Dusun Tuo at 7.36% of the total area. Impacts include damage to houses, agricultural land, public facilities, and disruption of accessibility between jorong. 2) the post-disaster management system has not been running optimally. Preparedness and mitigation efforts remain low, and rehabilitation focuses more on physical infrastructure, while social and psychological aspects remain largely unaddressed. Community capacity building, improved early warning systems, and better cross-sector coordination are needed for sustainable disaster management.

Abstract

This research is motivated by the high vulnerability to disasters, particularly flash floods (galodo), in West Sumatra, which is geographically prone to such events. The study seeks to evaluate and ascertain the state of infrastructure subsequent to the flash flood (galodo) disaster in Nagari Lima Kaum, Lima Kaum District, Tanah Datar Regency in May 2024. This quantitative research involves the population of areas affected by the flash flood (galodo), with the sample taken from four villages within the study area: Jorong Dusun Tuo, Balai Labuah Atas, Balai Labuah Bawah, and Piliang. Out of 797 households, 200 samples were selected using proportional random sampling. Primary data were collected through questionnaires and observations, while secondary data were obtained from the Wali Nagari Lima Kaum and the Disaster Management Agency of Tanah Datar Regency. Data analysis used the Likert scale to measure the level of damage. The findings indicated that the extent of infrastructure damage was classified as high, with a percentage of 80.56%. This damage primarily impacted residential structures and public amenities, including bridges and places of worship, whereas educational and healthcare facilities sustained comparatively minor damage.

Abstract

This study aims to analyze changes in land use along Jalan Baru Arosuka and their implications for spatial utilization in Solok Regency. The development of Jalan Baru Arosuka has improved accessibility and connectivity between regions, thereby encouraging the conversion of land from agriculture to residential, commercial, and public facilities. The research method used is mixed methods, combining spatial analysis using Geographic Information Systems (GIS) with a qualitative approach through in-depth interviews. Research data were obtained from Landsat and Sentinel satellite imagery for 2015, 2020, and 2024, as well as field surveys and questionnaires distributed to 98 heads of households on Jalan Baru Arosuka, Solok Regency. The research results show a decrease in the area of rice fields from 588.2 hectares in 2015 to 268.74 hectares in 2024, while the residential area increased from 37.6 hectares in 2015 to 85.10 hectares in 2024. The most significant changes occurred within a radius of 0–500 meters from the road, with the direction of residential and economic activity development following an east–west corridor. These land use changes impact increased economic activity, changes in the social structure of the community, and a potential decline in food security due to the reduction of productive land. These findings underscore the importance of spatial planning integrated with infrastructure development to achieve sustainable land use in Solok Regency.
