Abstract

Penelitian ini mengkaji perilaku lendutan balok baja melalui pendekatan Metode Elemen Hingga (MEH) dan pengujian eksperimental untuk memperoleh kurva beban–lendutan yang akurat. Tujuan utama penelitian ini adalah membandingkan respons struktural balok baja tipe IWF terhadap pembebanan lentur melalui dua pendekatan berbeda, yaitu simulasi numerik dan pengujian laboratorium. Analisis dilakukan pada balok baja dengan beban terpusat (three-point bending) untuk mengevaluasi kesesuaian hasil prediksi numerik terhadap fenomena fisik yang terjadi. Metode Elemen Hingga digunakan untuk memodelkan balok secara ideal dengan asumsi material elastis linier serta kondisi batas yang terkontrol. Sebaliknya, pengujian eksperimental dilakukan menggunakan Universal Testing Machine (UTM) dengan pemantauan lendutan melalui sensor LVDT. Hasil penelitian menunjukkan bahwa kurva beban–lendutan dari MEH dan hasil uji laboratorium memiliki kecocokan pola yang baik, terutama pada wilayah elastis. Perbedaan nilai lendutan maksimum sekitar 5–10% teridentifikasi sebagai akibat dari variasi sifat material aktual, imperfection struktural, serta deviasi kondisi tumpuan. Penelitian ini menegaskan bahwa MEH merupakan alat prediksi yang efektif dalam analisis perilaku lentur balok baja, namun tetap memerlukan validasi eksperimental untuk memastikan akurasi hasil perhitungan. Temuan ini bermanfaat dalam perencanaan struktur baja, khususnya untuk memastikan keselamatan dan efisiensi desain.

Abstract

This study analyzes the availability of clean water in Muara Enim Regency by focusing on the balance between water resource potential and community water demand up to the year 2035. The analysis employs a water balance method using a descriptive qualitative and quantitative approach, based on the processing and evaluation of secondary data from multiple sources, including population data, climatological data, and information on the existing water supply system. The data were obtained from the Central Bureau of Statistics (BPS), the Meteorology, Climatology, and Geophysics Agency (BMKG), as well as the Water Supply System Master Plan (RISPAM) of Muara Enim Regency as a technical reference. The results of the analysis indicate that the Enim River has an average discharge of approximately 56 m³/s, equivalent to 4.8 billion liters per day, while domestic water demand in 2025 is estimated at 11.86 million liters per day and is projected to increase to 13.79 million liters per day by 2035. The water balance analysis conducted in this study reveals a surplus of approximately 4.82 billion liters per day, indicating that water availability is quantitatively sufficient. Nevertheless, the analysis also shows that the capacity of water treatment and distribution systems remains suboptimal, as reflected by limited treatment capacity and relatively high water losses. Based on the calculations and evaluations carried out in this study, it is recommended to increase water treatment capacity, develop balancing storage facilities, and rehabilitate the distribution network in order to reduce water losses and improve clean water service coverage by 2035.

Abstract

Beam–column connections are critical components in seismic-resistant steel moment frame systems. This study aims to evaluate the behavior of Extended End-Plate (EEP) connections through a systematic literature review and statistical analysis of secondary data. The research method adopts a systematic literature review approach with quantitative data analysis derived from five main research journals published between 1997 and 2021. The data were extracted and analyzed using SPSS 25 software through descriptive statistical analysis, Pearson correlation, multiple linear regression, and one-sample t-test. The results indicate that: (1) there is a very strong positive correlation between end-plate thickness and connection moment capacity (r = 0.892; p < 0.01); (2) 67% of connection configurations with end-plate thickness ≥ 15 mm satisfy the minimum inelastic rotation criterion of 0.03 rad based on the FEMA-350 standard; and (3) end-plate thickness contributes dominantly (71.4%) to the increase in moment capacity compared to the number of bolts (28.6%). The recommended optimal configuration is an EEP connection with a 15 mm end-plate thickness and six bolts, producing a moment capacity of 56.8 kNm and an inelastic rotation of 0.042 rad. This study provides practical implications as a basis for recommending EEP connection design for steel buildings in seismic regions of Indonesia

Abstract

Occupational Safety and Health (OSH) is an essential aspect in the management of multi-storey buildings, particularly in emergency situations such as fires, earthquakes, or other hazardous events. One of the key elements in implementing OSH is the availability of safe, clear, and accessible evacuation routes for all building occupants. This Community Service Program (Kuliah Kerja Nyata/KKN) aims to analyze the Occupational Safety and Health (OSH) evacuation routes in the Universitas Mpu Tantular building, which consists of eight floors, focusing on evacuation routes from the 1st to the 8th floor and from the 8th floor to the 1st floor. The method used in this activity was an observational and descriptive approach through direct field observations of evacuation routes, including emergency staircases, evacuation corridors, exit access, and evacuation signage. The results show that the Universitas Mpu Tantular building is equipped with evacuation routes that can be used during emergency conditions. However, several aspects still require improvement, such as the visibility and consistency of evacuation signage on each floor, potential obstacles along evacuation corridors, and the optimization of emergency lighting. This KKN activity contributes to increasing awareness and preparedness regarding Occupational Safety and Health (OSH) implementation through the evaluation of evacuation routes to enhance the safety of building occupants

Abstract

the integration of Tekla structural models with plant design platforms such as AVEVA E3D and Intergraph Smart 3D (SP3D), along with model federation in Autodesk Navisworks, is employed to facilitate clash detection, staged 30–60–90% model reviews, and multidisciplinary decision‑making. The study adopts a descriptive research design using a literature review approach, complemented by the author’s reflective experience as a civil–structural Tekla Designer during the DED phase, to formulate a conceptual BIM integration model within the framework of a Common Data Environment (CDE), ISO 19650 standards, and Level of Development (LOD). The findings suggest that consistent LOD definition, robust information governance in the CDE, disciplined management of clash tests in Navisworks, and a structured 30–60–90% model review scheme are critical in improving multidisciplinary coordination and reducing rework during DED. The proposed conceptual model is expected to provide an initial reference for practitioners and academics in designing BIM‑based workflows for Tekla–E3D/SP3D–Navisworks integration in EPC oil and gas projects.

Abstract

Design–construction conflicts are one of the major challenges in toll road construction projects, which often lead to delays, cost overruns, and reduced construction quality. These conflicts are commonly caused by inconsistencies in technical drawings, insufficient multidisciplinary coordination, and limitations in technical communication between planning and implementation teams. This study aims to analyze the integration of multidisciplinary technical drawings and the optimization of Computer Aided Design (CAD) usage as an effort to prevent construction design conflicts in toll road projects. The research method employs a structured literature review and descriptive analysis of planning and construction practices commonly applied in toll road projects in Indonesia. The results indicate that effective integration of technical drawings, supported by standardized CAD practices such as layer management, drawing coordination, and systematic design revisions, can significantly improve coordination effectiveness and reduce the potential for design conflicts during construction. The study concludes that CAD-based multidisciplinary drawing integration represents a practical, realistic, and applicable approach for large-scale infrastructure projects, particularly in contexts where full implementation of Building Information Modeling (BIM) has not yet been fully adopted.

Abstract

The modular construction method is an innovation in the construction industry aimed at increasing project efficiency. This study aims to analyze the effect of implementing the modular construction method on time and cost efficiency compared to conventional construction methods. The study used a quantitative descriptive approach, using a case study of the construction of an office building in Grabag District, Purworejo Regency. Data were obtained from cost planning documents (RAB), project scheduling, and relevant supporting literature. The cost analysis showed that the modular method required a cost of Rp3,646,018,620.52, an 18.11% increase compared to the conventional method of Rp3,086,929,413.11. However, in terms of time, the modular method was able to shorten the construction duration from 150 days to 87 days, a 42% increase. The results showed that the modular method was superior in terms of time efficiency, while the conventional method was more economical in terms of cost. The choice of construction method should be adjusted to project priorities.

Abstract

Reliable irrigation water supply is a crucial factor in supporting sustainable agricultural development, particularly in watershed areas where river discharge fluctuates significantly throughout the year. In many cases, excess water during the rainy season cannot be effectively utilized, while water shortages occur during the dry season, limiting agricultural productivity. This study aims to develop an irrigation dam planning scheme as a water storage and regulation structure capable of ensuring continuous irrigation water availability. The analysis includes hydrological assessment to determine water availability potential, calculation of irrigation water demand based on land characteristics and cropping patterns, and reservoir capacity planning in accordance with local topographic conditions. In addition, the technical design of the dam is evaluated through dimensional planning and stability analysis against sliding, overturning, and slope failure. The results indicate that the proposed dam has sufficient storage capacity to meet irrigation water demands and satisfies structural safety requirements. The implementation of this dam planning is expected to improve water resource utilization efficiency and strengthen agricultural sustainability within the studied watershed area.
