Abstract

The 2018 flash flood in Banyuwangi Regency highlighted the role of sedimentation in increasing disaster risks. This study aims to analyze sedimentation rates based on real-time unsteady flow data during the rainy and dry seasons, understand the relationship between unsteady flow and sedimentation, and evaluate the role of HEC-RAS in mitigating sedimentation-related risks. Hydrometric measurements were conducted in real-time over seven days in both seasons. Data were analyzed using HEC-RAS and validated using the Mean Absolute Error (MAE) method of bathymetric measurements. The results show that sedimentation rates were higher during the rainy season (2.77 m³/day) compared to the dry season (1.33 m³/day) due to increased discharge and flow velocity. Flow velocity correlates more strongly with sedimentation than discharge, with regression values of 0.8257 in the dry season and 0.4072 in the rainy season. Flood modeling with HEC-RAS indicates that sedimentation increases flood risks, particularly in downstream areas. Therefore, mitigation measures such as river normalization, embankment construction, drainage optimization, and upstream soil conservation are necessary. These findings also support early warning systems to enhance community preparedness for sedimentation-induced floods.

Abstract

Building A of the State University Hospital (RSPTN) of Jember University, with a structural height of 22 meters, consisting of 4 floors and one roof, requires a comprehensive evaluation of seismic performance by SNI 1726:2019 and SNI 2847:2019. This study aims to assess the structural strength and seismic performance of the upper structure using Response Spectrum Analysis and Time History Analysis methods. The analysis was conducted using ETABS v22 software, with input data including architectural and structural drawings, material properties, and loading conditions. Gravity loads (dead, additional dead, and live loads) and seismic loads were applied, with dynamic analysis performed through two approaches: response spectrum analysis using site-specific parameters (SS = 0,8680, S1 = 0,3884, soil type SD), and time history analysis using spectrally matched records from the Tohoku (1999), Iwanuma (2005), and Vina Del Mar Centro (2010) earthquakes. The analysis results show that the structure"™s fundamental period is 0,7372 seconds, and base shear values meet design expectations. Inter-story drifts under the response spectrum remain within permissible limits; however, drifts under the time history exceed the threshold, particularly under inelastic conditions. Despite this, structural components, such as beams, slabs, and columns, fulfill the requirements for flexural, shear, and torsional strength.

Abstract

The irrigation system is one of the key factors influencing agricultural land productivity, particularly in rice fields. Proper and efficient water resource management is a crucial strategy to enhance agricultural production efficiency. The Turus irrigation area, covering 424 hectares, frequently faces challenges in water distribution due to both oversupply and inaccuracies in determining cropping patterns. This study aims to optimize irrigation water allocation in the area to achieve maximum agricultural output. The optimization process involves comparing the water requirements for specific crops with the available water supply to determine the most beneficial allocation. The results show that the water requirement during the second dry season planting period (MK II), from July to October, reaches 5.405,59 m ³/ha. Based on the water balance analysis and limited water availability, the optimization is focused on rice and secondary crops during the MK II season. Through a dynamic programming approach, an optimal water allocation was achieved, successfully irrigating the entire 424-hectare area and yielding a maximum profit of IDR 6.538.080.000,00. These findings demonstrate that optimizing water allocation using the dynamic programming method is a strategic approach to improving the efficiency and productivity of the irrigation system.

Abstract

The construction industry is experiencing increasing complexity that has an impact on occupational safety risks. Dynamic work environments trigger workers' non-compliance with established safety procedures. Many construction projects experience work accidents due to weak SMK3 implementation systems in the field. Workers often ignore safety instructions due to lack of motivation, weak organizational culture, and low risk understanding. This study aims to analyze the factors that influence compliance with SMK3 among construction project workers. This study uses a qualitative approach based on literature review through a systematic analysis of academic sources published in 2023–2025. This study reveals that organizational culture, intrinsic motivation, risk understanding, and technology utilization have a major contribution to worker compliance. Systems that involve workers in formulating safety policies show higher levels of compliance. Application-based surveillance technology helps improve worker reporting and awareness in the field. Risk-based training that is developed in an applicative manner has proven to be more effective than formal training. This study concludes that compliance with SMK3 is formed through synergy between managerial systems and individual behavior. Companies need to build a safety culture that is applied consistently across all project lines. Project management needs to provide simulation-based training and real-time reporting systems to increase risk awareness. Researchers recommend an integrative strategy involving two-way communication, safety incentives, and the use of adaptive technology to establish sustainable compliance. A safety system that is adapted to field realities will increase the effectiveness of SMK3 implementation in the construction sector.

Abstract

The construction industry experiences high levels of work accidents in road infrastructure projects. Work accidents have a negative impact on worker safety and project productivity. An Occupational Safety and Health Management System (SMK3) is needed to create a safe and healthy work environment. This study aims to analyze the implementation of SMK3 in improving work safety in road projects. This study uses a qualitative approach based on a literature review of academic sources published between 2023 and 2025. This study identifies five important elements in SMK3, namely safety training, procedural compliance, management support, safety culture, and system evaluation. This study found that safety training increases risk awareness and compliance with work procedures. A consistent evaluation system strengthens the system's adaptation to changing project conditions. This study also shows that project management plays an important role in creating a conducive work climate. Two-way communication between workers and management improves understanding of risks in the field. Safety technology has been shown to support real-time hazard detection and accelerate preventive actions. Worker participation in the preparation of safety policies encourages a sense of ownership of a safe work system. This study concludes that a holistic approach strengthens the success of SMK3 implementation in road projects. This study recommends the integration of SMK3 from the planning stage to project implementation. Companies must build an adaptive, collaborative, and risk-based safety management system. The government needs to strengthen safety regulations and improve supervision in the field systematically.

Abstract

Kabupaten Banyuwangi merupakan wilayah dengan aktivitas seismik tinggi yang menuntut penerapan desain struktur tahan gempa. Penelitian ini mengevaluasi kinerja seismik struktur gudang baja eksisting dengan sistem Ordinary Moment Frame (OMF) dan membandingkannya setelah dimodifikasi menjadi sistem Ordinary Concentrically Braced Frame (OCBF). Analisis dilakukan menggunakan metode Linear Time History Analysis (LTHA) pada ETABS v22, dengan input tiga data gempa historis (Chi-Chi, Miyagi, Tokachi). Hasil menunjukkan bahwa struktur OMF mengalami overstress pada elemen kolom (rasio tegangan D/C sebesar 0,951), rasio kelangsingan KL/r mencapai 205,49 (melebihi batas 200), serta simpangan antar tingkat sebesar 249,22 mm (2,6%), melampaui batas izin 143,077 mm. Setelah modifikasi ke sistem OCBF, nilai D/C turun menjadi 0,785, rasio KL/r menjadi 141,84, dan simpangan antar tingkat berkurang drastis menjadi 70,09 mm (0,7%). Dengan demikian, penambahan bracing terbukti efektif meningkatkan performa seismik struktur baja pada kawasan rawan gempa.
