Gunung dempo yang terletak di Kota Pagar Alam memiliki potensi erupsi yang dapat membahayakan masyarakat di sekitarnya, sehingga dibutuhkan perencanaan jalur evakuasi yang efektif. Penelitian ini bertujuan untuk menganalisis kinerja jaringan jalan dalam mendukung proses evakuasi bencana erupsi Gunung Dempo. Analisis dilakukan menggunakan pendekatan four-steps model berdasarkan data geometri jalan, survei arus lalu lintas pada jam puncak, kuesioner dari masyarakat dan pengunjung pariwisata, serta pemodelan eksisting dan simulasi beberapa skenario saat evakuasi. Dari pemodelan eksisting akan dilanjutkan dengan beberapa skenario yaitu Skenario 1 saat evakuasi tanpa perubahan geometri jalan, Skenario 2 dengan pelebaran jalan, dan Skenario 3 yang dikembangkan dari Skenario 2 dengan mempertimbangkan penambahan jalan baru sebagai alternatif. Hasil kuesioner menunjukkan bahwa mayoritas masyarakat memilih menggunakan sepeda motor dibandingkan mobil sebagai alat transportasi saat evakuasi, yang mengindikasikan penggunaannya yang cepat dan fleksibel. Hasil analisis menggambarkan bahwa penyebaran arus lalu lintas pada pemodelan eksisting sesuai dengan kondisi nyata di lapangan. Penelitian ini menunjukkan bahwa hasil Skenario 1 dengan kondisi eksisting sekarang yang menggunakan volume evakuasi memperlihatkan bahwa pelayanan jalan sudah tidak memadai. Oleh karena itu, pada Skenario 2 dan Skenario 3 mempertimbangkan adanya pelebaran jalan dan penambahan jalur aman baru dalam mendukung proses evakuasi. Dari hasil analisis terlihat bahwa adanya pelebaran jalan dan penambahan jalan baru relatif lebih mampu mengakomodir peningkatan volume arus lalu lintas saat evakuasi.

Pencemaran tanah oleh logam berat menjadi masalah lingkungan serius. Artikel ini bertujuan untuk mengkaji mekanisme dan aplikasi fitoremediasi sebagai metode alternatif dalam pemulihan tanah tercemar logam berat. Metode yang digunakan adalah studi deskriptif berbasis kajian literatur. Hasil menunjukkan bahwa fitoremediasi bekerja melalui tiga mekanisme utama: fitoekstraksi, fitostabilisasi, dan rizodegradasi. Beberapa tanaman hiperakumulator seperti Amaranthus hypochondriacus, Vetiveria zizanioides, dan Brassica juncea terbukti efektif menyerap dan menstabilkan logam berat seperti Cd, Pb, Cr, dan As. Efektivitasnya meningkat dengan penggunaan amandemen seperti biochar dan kompos. Selain mereduksi kandungan logam, fitoremediasi juga memperbaiki kondisi biologis tanah. Dengan keunggulan biaya rendah, keberlanjutan, dan dampak lingkungan minimal, fitoremediasi berpotensi menjadi solusi strategis dalam pemulihan tanah tercemar.

Introduction/Main Objective: Labor force participation is crucial for improving household economic conditions. Theoretically, labor force participation in the job market can be influenced by several factors, including poverty levels. Documentation from the Central Bureau of Statistics (BPS) of Jambi Province indicates that labor force participation rates vary across districts and cities in the province. This study aims to estimate the impact of poverty levels on labor force participation rates in Jambi Province. In this analysis, labor force participation is categorized into male and female labor force participation rates. Research Methodology: This study employs panel data from districts and cities during the 2018–2023 period. All data are sourced from published reports by the Central Bureau of Statistics (BPS) of Jambi Province. To estimate the relationship between variables, the study utilizes panel regression analysis with a fixed-effects approach. Findings/Results: The study demonstrates that poverty levels have a positive and significant impact on male and female labor force participation rates. The higher the poverty level, the higher the male and female labor force participation in the job market. Conversely, lower poverty levels are associated with lower labor force participation rates. Conclusion/Recommendations: Labor force participation in the job market is significantly determined by poverty levels. In other words, the challenges faced by households in meeting their basic needs drive increased participation in the job market. Therefore, it is recommended that district and city governments in Jambi Province enhance labor force participation by providing training and skills development programs, particularly for impoverished groups.

Bengkulu Province, located along the western coast of Sumatra, is one of Indonesia’s most seismically vulnerable regions due to its proximity to major tectonic boundaries. This study aims to enhance earthquake-resilient infrastructure planning by developing a two-dimensional geospatial model of key geotechnical parameters—Plasticity Index (PI) and water content (ѡ) —in the coastal zone. A total of 65 geotechnical observation points served to generate detailed maps by using the Inverse Distance Weighting (IDW) method down to 30 meters depth. The model integrates empirical correlations with statistical and spatial analyses to overcome the challenges of limited data. Results highlight distinct geotechnical variations across different soil layers and administrative regions, revealing zones with high liquefaction potential. The findings provide insight for engineers, urban planners, and disaster risk authorities in designing site-specific construction strategies. This research fills a critical gap in the current literature regarding Inverse Distance Weighting (IDW)-based geospatial modelling in seismically active areas. It offers a replicable framework for other coastal regions with similar geological contexts. Keywords: Plasticity Index; Water Content; Geospatial modeling; Inverse Distance Weighting (IDW)

South Sumatra is a province on the island of Sumatra, positioned along the boundary between the Indo-Australian Plate and the Eurasian Plate. The tectonic interaction between these plates has resulted in a mountain range that extends longitudinally from the island’s northern to southern regions, a geological condition that contributes to the area’s susceptibility to natural hazards, one example is the Dempo Volcano. This study uses the four-step model method to analyse the vulnerability of the road network on evacuation routes during the eruption of Dempo Volcano in Pagar Alam City. Eight road sections were observed. A comparison of traffic survey results and numerical modelling was conducted to assess the consistency of the model and also to predict critical conditions. Scenario 1 represents evacuation conditions without any changes to road geometry, while Scenario 2 represents evacuation conditions with modifications in the form of road widening. The analysis showed that most of the population prefers motorcycles as a mode of transport and the fastest route during evacuation, considering the faster evacuation time. Scenario 1 showed a surge in traffic volume, which became an obstacle to evacuation. Scenario 2 can increase capacity and improve traffic flow. The Vulnerability Index indicates that some road sections are vulnerable to evacuation impacts.
