Abstract

During the 2006 Yogyakarta earthquake, liquefactions were massively found in Opak River, Yogyakarta, Indonesia. Learning from those events, an experimental study of liquefaction using shaking table was performed, especially to investigate the effect of short shaking duration to liquefaction potential.  Several experimental tests were performed under varied accelerations (0.3g, 0.35g, and 0.4g) and vibration frequencies (1.4 Hz, 1.6 Hz, and 1.8 Hz), with a short shaking duration of 8 seconds. The liquefaction parameter used in this study was the excess pore water pressure ratio. The results revealed that liquefaction occurs in every loading criteria and the short shaking duration applied on each loading influences time stages of liquefaction, i.e. the liquefaction duration, the initial time of liquefaction, and the initial time of pore water pressure dissipation. In addition, the dynamic loads applied in a short duration influenced the maximum excess pore water pressure ratio.

Abstract

Gedung J Universitas Bengkulu merupakan gedung kuliah yang digunakan oleh Fakultas Hukum. Gedung J sangat dekat dengan bibir pantai menyebabkan gedung ini sangat rawan terhadap bencana tsunami. Jalur evakuasi bencana sangat dibutuhkan untuk menanggulangi dan mengurangi korban jiwa. Penelitian ini bertujuan untuk merencanakan model perjalanan evakuasi bencana tsunami dan mengatasi ruas jalan yang bermasalah. Penelitian ini menggunakan metode Agent Based Modelling dengan bantuan aplikasi NetLogo versi 6.0.4. Data primer yang digunakan adalah denah gedung dan geometri jaringan jalan. Data sekunder yang diperlukan meliputi jumlah orang yang ada didalam gedung kuliah. Pengambilan kuisioner dilaksanakan dengan pengambilan sampel, kemudian data dianalisis secara statistik meliputi uji validitas data, derajat kejenuhan, volume, kapasitas, dan tes analisis regresi linier sederhana. Penelitian ini menggambarkan12 ruas jalan dan 3 rute alternatif. Analisis data yang dilakukan menunjukkan kondisi ruas jalan yang ditinjau berdasarkan hasil perbandingan data kuisioner dan simulasi. Rute alternatif evakuasi yang banyak dipilih responden adalah rute alternatif 1, hal ini dikarenakan jalan terdekat ketika pengungsi menuju pintu keluar. Selain itu, nilai derajat kejenuhan serta kapasitas yang tinggi menunjukkan perlunya pengembangan kinerja jaringan jalan lokal Universitas Bengkulu, sehingga ketika evakuasi tidak terjadi hambatan bagi pengungsi.

Abstract

Kebakaran tidak dapat diprediksi, baik lokasi, intensitas dan laju pertumbuhannya. Pada kejadian kebakaran di fasiltas umum yang sedang digunakan, ratusan bahkan ribuan orang harus di evakuasi dalam kondisi yang beresiko dan berbahaya. Misalnya, harus mengevakuasi gedung sekolah, rumah sakit, atau pusat pembelanjaan. Jika suatu bangunan didesain menggunakan kode dan aturan konstruksi yang modern, usaha untuk mengendalikan sebaran api pada kejadian kebakaran agar tidak menyebar akan lebih mudah dilakukan. Berdasarkan kunjungan tim dan diskusi yang telah dilakukan bersama mitra yaitu SMP Negeri 5 Kota Bengkulu, maka teridentifikasi beberapa permasalahan yang memerlukan penyelesaian segera. Mengingat dampak kebakaran yang bisa fatal, maka kegiatan penyediaan media informasi inni sangat perlu dilakukan. Pelaksanaan Program Pengabdian Pada Masyarakat Mandiri ini bertujuan untuk menyediakan media informasi mengenai evakuasi kebakaran di SMP Negeri 5. Kegiatan ini dilakukan sebagai mitigasi resiko kebakaran. Indikator penting keberhasilan kegiatan PPM ini diukur dari telah tersedia media informasi dan alat pemadam api ringan di SMP Negeri 5 Kota Bengkulu

Abstract

The position of Bengkulu Province, which is flanked by the subduction zone between the Euro-Asian and Indian-Australian plates to the west, and the Sumatra Fault zone to the east, makes Bengkulu City one of the areas prone to earthquake disasters. Muara Bangkahulu District is one of the sub-districts in Bengkulu City. Muara Bangkahulu sub-district is an area that functions as a government centre, trade and service centre, and one of the education centres in Bengkulu City. This study aims to determine the ground response in the Muara Bangkahulu sub-district area during an earthquake. The wave propagation method used in this study is a one-dimensional equivalent of linear and nonlinear modelling that propagates earthquake waves from bedrock to surface. The results of this study are Peak Ground Acceleration (PGA), amplification factor, earthquake acceleration time history, and acceleration spectra response. The results of this analysis will be compared between equivalent linear and nonlinear values. The results of this study can also help us realise and further consider the value of seismic design in the Muara Bangkahulu sub-district area, mainly if a stronger earthquake occurs in the future.

Abstract

Pulau Baai Port in Bengkulu City is a densely active area with a high risk of being affected by a tsunami disaster. This study aims to model the road network and analyze its performance during evacuation using the Four Step Model method. Surveys were conducted to assess existing conditions, build evacuation movement scenarios, and model the effect of road capacity improvements. The results show an R² value of 0.8502, indicating that the modeling is valid compared to real field conditions. The evacuation modeling produced the highest degree of saturation on several road segments, reaching 0.91, 0.75, and 0.70, indicating a high risk of congestion during evacuation. Increasing road capacity proved effective in reducing traffic density, lowering the degree of saturation to 0.78, 0.69, and 0.54. Therefore, road widening can serve as an effective solution for planning better evacuation routes.

Abstract

Labour productivity plays an important role in determining the success of a construction project, especially in lightweight masonry work, which requires high skills and affects not only the aesthetic aspect but also the durability of the building with lightweight materials suitable for high-rise buildings. This study aims to analyse the factors affecting the productivity of lightweight masonry labour on The Establishment of the University of Bengkulu's Hospital Project. The research method used is direct observation in the field, with the work sampling method using the productivity rating approach to calculate the labour utilization rate (LUR) level. The questionnaires were distributed to lightweight masonry workers to identify factors that affect productivity. Data were analysed using validity tests, reliability tests, and the Relative Importance Index (RII) analysis, and relationships between factors were looked for using matrix correlation. The results showed that the average LUR for the level of productivity of lightweight masonry labour was 63.89% which was categorised as productive because it was above 50% with the dominant factor affecting field conditions including the availability of tools, weather, and relationships between workers with an RII value of 0.88 which is included in the high level of importance. The findings contribute to managing labour productivity in construction projects and recommend improving tool management and fostering teamwork in the field.

Abstract

This study aims to assess the impact of earthquakes on the Professional Programme Lecture Building at the Faculty of Teacher Training and Education (FTTE), Bengkulu University, by integrating soil response analysis and structural dynamics. The research began with the collection of geological data at the research site. Seismic soil response analysis was conducted to assess soil movement at the end of the piles, followed by earthquake wave propagation to evaluate the building's response to earthquake activity using the Finite Element Method (FEM). Based on load ratio evaluations, beam B2 and column C2 on the second floor of the building were identified as having structural weaknesses. Therefore, retrofitting techniques were applied to increase the load capacity of the structure. The results showed that retrofitting provided significant improvements in structural performance. This research highlights the importance of integrating soil response analysis with structural dynamics to enhance the resilience and safety of buildings in earthquake-prone areas.
