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

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

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.

Abstract

Kota Bengkulu kerap mengalami kemacetan, terutama di sekitar Jalan Mayjen Sutoyo depan Sekolah IT Rabbani. Penelitian ini bertujuan menganalisis sensitivitas kinerja jalan akibat aktivitas sekolah. Data diperoleh melalui survei lalu lintas dan dianalisis berdasarkan kondisi eksisting dan dua skenario perubahan jam masuk sekolah. Pada kondisi eksisting, derajat kejenuhan 0,45 (tingkat pelayanan C), kecepatan 50 km/jam, dan waktu tempuh 3,31 menit. Skenario 1 (kelas 4–6 masuk pukul 07.30 WIB) menurunkan derajat kejenuhan menjadi 0,40 (indeks sensitivitas 11%), meningkatkan kecepatan menjadi 52 km/jam (4%), dan menurunkan waktu tempuh menjadi 2,58 menit (22%). Skenario 2 (kelas 1–3 masuk pukul 08.30 WIB) menurunkan derajat kejenuhan menjadi 0,42 (6%), kecepatan naik menjadi 51 km/jam (6%), dan waktu tempuh turun menjadi 3,09 menit (2%). Jalan Mayjen Sutoyo tergolong kurang sensitif terhadap perubahan volume lalu lintas

Abstract

Sesar Lembang merupakan sesar aktif yang terletak di bawah tanah di Jawa Barat, Indonesia. Sesar ini memiliki panjang sekitar 30 km dan bergerak dengan kecepatan sekitar 2,5 cm per tahun. Sesar Lembang terletak di bawah daerah Lembang, Kabupaten Bandung Barat, dan berpotensi menyebabkan gempa bumi dengan magnitudo yang signifikan, mencapai 7,0 SR. Salah satu wilayah yang akan berdampak cukup parah akibat sesar lembang ini adalah SMA Negeri 1 Lembang. Tujuan dari pengabdian masyarakat ini adalah untuk memberikan edukasi terkait gempa bumi pada sivitas sekolah SMAN 1 Lembang serta penerapan teknologi tepat guna sebagai solusi mitigasi bencana gempa, terutama gempa bumi akibat Sesar Lembang. Hasil pelaksanaan pengabdian masyarakat ini adalah peta jalur evakuasi, rambu dan marka jalur evakuasi, pelatihan dan sosialisasi strategi menghadapi bencana untuk siswa, guru, serta sivitas sekolah lainnya. Peningkatan pengetahuan dan kesadaran sivitas sekolah meningkat sebanyak 50% yang terlihat dari hasil kuesioner pengetahuan mengenai kebencanaan khususnya akibat Sesar Lembang.

Abstract

Sedimentation in drainage channels can reduce flow capacity and cause flooding. This study aims to analyze sediment characteristics, sediment transport capacity, and its impact on drainage channels in Sumber Jaya Village, Bengkulu City. Sediment samples were taken from five points 100 meters apart, then tested in the laboratory to determine their physical properties and analyzed using empirical and numerical methods, namely Meyer-Peter Müller, Ackers - White, and DuBoys. The test results showed that the sediment was dominated by poorly graded sand with silt or clay content. The average sediment transport capacity obtained was 150.6398tons/year using the empirical Meyer-Peter Müller method, 153.9395 tons/year using the numerical modeling of Meyer-Peter Müller, 188.409 tons/year using the DuBoys method, and 57.816 tons/year using the Ackers - White method. The average sedimentation percentage of drainage channels reached 12.38% and was classified as a sufficient channel. The results of this study confirm that sedimentation has a significant effect on drainage capacity, requiring rehabilitation measures and further study. These findings are expected to form the basis for sediment management and sustainable drainage infrastructure planning in urban areas.
