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. Keywords: Disaster Evacuation; Four Steps Models; Dempo Volcano Eruption; Road Network Modelling; Vulnerability Index.

Soil is an essential and indispensable material in civil engineering and building design, affecting various construction works. The primary function of soil is to support the construction load built on it, so the soil must be able to carry the load. Each type of soil has different characteristics, so it requires special handling, both physically and mechanically. This research aims to determine the soil's physical and mechanical properties and its application using the finite element method in the Sawah Lebar Baru area, Bengkulu City. The Sawah Lebar Baru area is currently developing a new residential area. Based on the tests conducted, the soil in the area is classified as silt with high plasticity (MH). The tests include physical tests such as moisture content, volume weight, specific gravity, grain size analysis, and Atterberg limits, as well as mechanical tests such as free compressive strength test, consolidation test, and direct shear test. The results of this study provide information on the type, characteristics, physical and mechanical properties of soil, as well as its application in geotechnical design. The foundation design test results showed that the maximum vertical load was 32,900 kN/m², and the safety factor value was 3.047 for the 0.5 m depth variation. The maximum vertical load value in the foundation with a depth variation of 0.75 m is 67,500 kN/m², and the most significant safety factor value is 5.909. For the depth variation of 1 m, the maximum vertical load value is 118,050 kN/m², and the safe factor value is 9.864.

Labor productivity is the main parameter in the success of a construction job. This study aims to analyze the level of productivity and the level of Labor Utilization Rate (LUR) in plastering work using the work sampling method, and the most effective time correlation between morning and afternoon. This research was conducted by direct observation for 3 days. The results showed that the highest productivity value was 14.30 m²/hour in the afternoon, and the lowest productivity value was 6.86 m²/hour in the morning. The Labor Utilization Rate (LUR) values in the morning and afternoon were 57.9% and 65.9%, indicating that the afternoon time was more effective than the morning time. However, there was a significant difference in productivity between morning and afternoon time overall, and it can still be categorized as effective with a Labor Utilization Rate (LUR) value of 61.9%, which exceeds 50%.

This study analyzes the liquefaction potential in the coastal area of Bengkulu due to the large subduction earthquake in 2007. The study was conducted systematically, beginning with field investigations with shear wave velocity measurements. Spectral matching and ground motion prediction based on relative attenuation models were conducted to obtain a representative picture of ground motion at the study site. Subsequently, soil response analysis was used to evaluate the behaviour of the soil under seismic loading. A non-linear finite element approach was applied to assess the dynamic characteristics of the soil, including excess pore water pressure, shear stress-strain response, and stress path. In addition, an empirical evaluation was conducted to determine the liquefaction potential. The results show that liquefaction has the potential to occur at shallow depths, especially in the first and second layers of the sand layer. The results of numerical and empirical analyses show consistent patterns and agreement. The comparison between the excess pore pressure ratio and the safety factor aligns with the findings from previous studies. These findings emphasise the importance of implementing seismic hazard mitigation measures in the study area.

The Selebar District in Bengkulu City has a high level of earthquake vulnerability due to its location near the Indo-Australian and Eurasian plate subduction zone. This study began with a microtremor survey and earthquake modelling to analyse the seismic response of the soil. Modelling was conducted using the non-linear dynamic Pressure Dependent Hyperbolic (PDH) approach. This method models soil behaviour by considering changes in stiffness and damping due to variations in pressure and strain during an earthquake, thereby providing a more realistic representation of field conditions. The response analysis was conducted in one dimension and produced soil acceleration parameters, with Peak Ground Acceleration (PGA) values ranging from 0.47g to 0.75g. These results indicate a high earthquake potential in the study area. The acceleration spectrum of the input waves increased gradually until it reached its peak at a period of 0.2 seconds, covering the classification range of buildings from low to high. These findings provide essential input for earthquake-resistant infrastructure planning and the formulation of risk mitigation strategies in earthquake-prone areas, such as the Selebar District in Bengkulu City.

Kecamatan Selebar merupakan salah satu kecamatan di Kota Bengkulu yang memiliki beberapa infrastruktur vital. Kondisi geologi yang beragam dan aktivitas seismik yang masif menjadikan kawasan ini sebagai lokasi penting dalam studi geoteknik. Penelitian ini bertujuan untuk mengeksplorasi hubungan antara kecepatan gelombang geser (Vs) terhadap resistensi tanah di Kecamatan Selebar berdasarkan parameter kecepatan gelombang geser rata-rata (Vs) pada kedalaman 10 hingga 50 m (Vs10, Vs20, Vs30, Vs40, dan Vs50), kelas situs dan Ground Amplification Factor (GAF). Penelitian ini menggunakan data sekunder dari perekaman mikrotremor sebanyak 40 titik yang kemudian dianalisis dan divisualisasikan dalam bentuk peta sebaran dua dimensi berbasis Geographic Information System (GIS). Interpolasi spasial dilakukan menggunakan metode Ordinary Kriging dengan Spherical Semivariogram Model dan Inverse Distance Weighting (IDW) untuk memperoleh distribusi sebaran yang lebih akurat. Hasil penelitian menunjukkan bahwa nilai Vs10, Vs20, Vs30, Vs40, dan Vs50 di Kecamatan Selebar berkisar antara 100 hingga 1.100 m/s, dengan peningkatan kekakuan tanah seiring bertambahnya kedalaman. Kecamatan Selebar didominasi oleh kelas situs C, dengan beberapa zona B dan D, serta GAF antara 0.9 hingga 1,7. Penelitian ini diharapkan dapat memberikan gambaran mengenai respons tanah dan dapat menjadi referensi dalam upaya mitigasi serta pertimbangan dalam perencanaan pembangunan infrastruktur tahan gempa di Kecamatan Selebar, Kota Bengkulu.

This study is designed to model the tendency of Gedung PKM users, Universitas Bengkulu using Agent Based Modelling Method. The vehicle survey is performed to obtain the peak-time period of parked vehicles in Gedung PKM. The questionnaire collecting is performed to obtain the information, which are later used to volume capacity ratio, volume, and road capacity. In this study, several road segments and alternative routes are observed during the evacuation. To inspect the suitability between the modelling and the observation, the simple linear regression analysis is performed. The results show that the most selected route is the shortest route with the best accessibility to reach the gateway, during the evacuation. The road saturation degree shows that there is a need to improve the local road performance in Universitas Bengkulu to ensure a faster evacuation process during tsunami.
