Abstract

This study aims to analyze the effect of implementing Building Information Modeling (BIM) using Autodesk Revit on the accuracy of structural Quantity Take-Off (QTO) in the Abelia Resto & Gallery project. Detail Engineering Design (DED) data and the Cost Budget Plan (RAB) were modeled in Revit 2024 to generate volume and cost estimates for concrete and reinforcement, which were then compared with manual calculation results. The results show that the average volume deviation is below 5%, except for the gallery foundation (-15.32%) and the restaurant floor slab (-9.60%). Concrete cost estimates generated using Revit are lower than those obtained through manual methods, with deviations of -4.65% for the restaurant and -1.57% for the gallery, while reinforcement costs decreased for the restaurant (-9.68%) and increased for the gallery (3.82%). These differences are caused by the quality of input data, the level of modeling detail, and differences in assumptions used in manual methods. The study concludes that Revit-BIM is capable of improving the accuracy and efficiency of the QTO process for structural works, although field verification is still required to ensure conformity with actual site conditions. This research recommends the use of Revit-BIM as the primary supporting tool for project cost estimation, particularly at the early planning stage, to improve quantity accuracy and calculation time efficiency.

Abstract

Transportation and logistics are strategic aspects in goods distribution, where loading and unloading activities in warehouse areas are key factors determining operational efficiency. Parepare City, as a regional logistics hub in South Sulawesi, still faces challenges such as limited facilities and long truck waiting times due to ineffective loading and unloading scheduling. This study aims to analyze warehouse characteristics, transportation modes, and measure the influence of the quantity of goods (X1), equipment and labor performance (X2), and loading and unloading time (X3) on productivity and effectiveness (Y). The method used is a descriptive quantitative approach through field observations, questionnaires, and documentation studies, with multiple linear regression analysis using SPSS version 27. The study covered six warehouses, consisting of three commercial warehouses, a steel material warehouse using forklifts, a fertilizer warehouse, and a rice warehouse using manual labor. The results show performance disparities, where the steel material warehouse using forklifts recorded the highest productivity of 51 pieces/minute with an R² value of 79.5 percent, while the rice warehouse only reached 8 sacks/minute. Simultaneous (F) and partial (t) tests confirmed that X1, X2, and X3 significantly influence Y. These findings emphasize that optimizing forklift utilization, improving labor competency, and improving loading and unloading scheduling are key factors in increasing logistics efficiency in the Parepare warehouse area.

Abstract

Pertumbuhan jumlah kendaraan bermotor di Kabupaten Garut menimbulkan kemacetan pada simpang bersinyal, terutama di Simpang Maktal yang menjadi penghubung pusat kota dengan jalur menuju wilayah selatan. Penelitian ini bertujuan menganalisis kinerja simpang sebagai dasar penerapan Area Traffic Control System (ATCS). Metode penelitian menggunakan pendekatan kuantitatif melalui survei lapangan pada jam puncak sore untuk memperoleh data volume lalu lintas dan rasio belok. Analisis kinerja dilakukan secara manual berdasarkan Pedoman Kapasitas Jalan Indonesia (PKJI 2023) yang meliputi perhitungan arus jenuh, kapasitas, derajat kejenuhan, tundaan, panjang antrean, dan tingkat pelayanan, serta dibandingkan dengan hasil simulasi menggunakan perangkat lunak PTV VISSIM Student Version 25. Hasil penelitian menunjukkan bahwa volume tertinggi terjadi pada pendekat B dengan derajat kejenuhan lebih dari 0,9, yang menandakan kondisi hampir jenuh. Perhitungan manual menghasilkan tundaan rata-rata sebesar 60 detik detik per satuan mobil penumpang dengan tingkat pelayanan D - F, sedangkan simulasi menunjukkan tundaan lebih tinggi pada setiap pendekat hingga mencapai tingkat pelayanan F. Temuan ini mengindikasikan bahwa penerapan ATCS berpotensi mengoptimalkan distribusi waktu hijau, menurunkan tundaan, serta meningkatkan efisiensi kinerja simpang bersinyal di Kabupaten Garut. Penelitian ini diharapkan dapat memberikan kontribusi dalam bidang rekayasa lalu lintas, khususnya pengembangan transportasi cerdas berbasis evaluasi kinerja simpang dan simulasi mikroskopis.

Abstract

Transportasi laut menjadi sarana utama yang sangat penting dalam memperkuat hubungan antar daerah di Indonesia, terutama bagi daerah kepulauan seperti Pulau Bawean. Salah satu layanan angkutan laut yang melayani rute Bawean–Gresik adalah Kapal Cepat Express Bahari. Penetapan tarif pada moda ini perlu memperhatikan keseimbangan antara kemampuan ekonomi dan kemauan membayar dari penumpang. Penelitian ini bertujuan untuk menganalisis kelayakan tarif menggunakan metode Ability To Pay (ATP) dan Willingness To Pay (WTP). Metode penelitian yang digunakan adalah survei kuisioner terhadap 100 penumpang Kapal Cepat Express Bahari, yang datanya dietelaah dengan pendekatan kuantitatif. Hasil yang diperoleh menunjukkan rata-rata ATP penumpang adalah Rp202.565,00, sedangkan rata-rata WTP sebesar Rp191.457,00. Nilai ATP lebih tinggi dari tarif saat ini sebesar Rp200.000,00, yang berarti penumpang memiliki kemampuan membayar tarif yang berlaku. Namun, WTP lebih rendah dari tarif eksisting, menunjukkan adanya ketidaksesuaian antara persepsi harga dan tarif aktual. Dengan demikian, meskipun secara ekonomi tarif masih terjangkau, perlu dilakukan evaluasi untuk memastikan tarif sesuai dengan nilai yang dirasakan oleh pengguna. Penelitian ini mendukung perumusan tarif transportasi laut yang adil dan berkelanjutan di wilayah kepulauan.

Abstract

Daerah Aliran Sungai (DAS) memilki fungsi sebagai penyangga tata air, namun dalam beberapa tahun DAS Cimanuk Hulu mengalami tekanan akibat perubahan tata guna lahan yang tidak terkendali. Penurunan luas hutan dan meningkatnya area terbangun berpotensi memperburuk kondisi hidrologi, ditandai dengan meningkatnya aliran permukaan serta menurunnya infiltrasi. Tujuan penelitian ini untuk menganalisis perubahan tutupan lahan 2017 dan 2024 serta dampaknya terhadap respon hidrologi pada DAS Cimanuk Hulu. Penelitian ini menggunakan pemodelan hidrologi dengan soil and water assessment Tool (SWAT) Analisis dilakukan melalui deliniasi DAS, pembentukan Hydrological Response Unit (HRU), pembangunan model hidrologi, serta kalibrasi menggunakan data debit harian periode 2015–2022. Penggunaan model Sacramento untuk memperkuat hasil kalibrasi debit sungai. Hasil penelitian menunjukkan bahwa antara tahun 2017–2024 luas hutan berkurang sebesar 1,466ha (3,12%), lahan pertanian menurun 1.137 ha (2,41%), sedangkan area terbangun meningkat 3.110 (6,62%). Perubahan ini berdampak pada peningkatan aliran permukaan (surface runoff), penurunan aliran dasar (baseflow), serta meningkatnya fluktuasi debit sungai. Nilai Koefisien Regim Aliran (KRA) tahun 2024 lebih besar dibandingkan 2017, yang mengindikasikan kestabilan hidrologi DAS menurun. Perubahan tata guna lahan di DAS Cimanuk Hulu secara nyata memengaruhi keseimbangan hidrologi dan meningkatnya risiko banjir pada musim hujan serta kekeringan pada musim kemarau.

Abstract

The objective of this study is to analyze road damage using the Bina Marga and PCI (Pavement Condition Index) methods. Both empirical methods are applied because they are commonly used to assess road damage in Indonesia. Road damage analysis using the Bina Marga method is carried out through several stages, including determining road type and classification, classifying the type and severity of damage, evaluating road damage, and recommending appropriate maintenance actions. The PCI method involves determining the Total Deduct Value (TDV), calculating the corrected deduct value, determining the PCI value, and recommending the type of road repair. The results of the Bina Marga method recommend routine maintenance, while the PCI method suggests structural rehabilitation. Considering the existing road damage conditions, routine maintenance is selected as the appropriate treatment. In the following year, if monitoring and evaluation show that damage still occurs at the repaired location, road improvement in the form of overlay is recommended.

Abstract

This study discusses the pressure on water availability resulting from population growth, increased economic activities, and changes in river discharge. These conditions create an imbalance between water supply and demand, highlighting the need for more planned and systematic water management. The objective of this research is to optimize the utilization and allocation of water resources in order to meet community needs in an equitable and sustainable manner. The method employed is a quantitative approach using the RIBASIM (River Basin Simulation Model). The research stages include collecting data on water availability and demand, developing management scenarios, and conducting simulations and result analyses to assess system reliability. The novelty of this study lies in the application of RIBASIM as an integrated water allocation optimization tool, utilizing adaptive scenarios to enhance distribution reliability in regions with high discharge variability. The RIBASIM model is used to evaluate how effectively water can be allocated to various sectors such as irrigation, public water supply, and industry. The results indicate discrepancies between water availability and demand that lead to reduced service levels in several sectors. After simulations and the implementation of strategies such as prioritizing water use, adjusting cropping patterns, applying rotational water distribution, and reusing wastewater, the reliability of the water management system improved. Overall, this study demonstrates that the use of the RIBASIM model can support more efficient planning and decision-making in water allocation. This model-based approach supports integrated and sustainable water resource management and can serve as a foundation for enhancing water security and community welfare in the future.

Abstract

Traffic accidents that frequently occur on the Patrol-Kamojang road section in Bandung Regency indicate a high safety risk due to the incompatibility of geometric conditions, particularly vertical alignment, with applicable technical standards. This study aims to analyze the characteristics of vertical alignment on this section, assess its effect on accident rates, and provide recommendations for improvement. Primary data was obtained through field surveys in the form of measurements of elevation, segment length, and slope using a theodolite, measuring rod, and tape measure. Secondary data consisted of a recapitulation of accidents from 2022 to 2024 from the police, including the frequency, location, and type of accidents. The analysis was conducted by comparing the geometric data with Bina Marga standards, calculating the accident rate using the Equivalent Accident Number (EAN), and setting the Upper Control Limit (UCL) for blackspot identification. In addition, the critical length and geometric adjustment requirements were calculated as the basis for technical recommendations. The results of the study show that several segments have a slope of up to 33.84%, exceeding the safety limit and correlating with an above-average EAN value and exceeding the UCL, thus being designated as priority blackspots. This study identifies accident-prone locations and recommends vertical alignment improvements, and can be used as a reference for relevant agencies in improving traffic safety on hilly roads.

Abstract

The Sirnajaya–Papandayan road segment in Cisurupan District, Garut Regency, serves as a primary access route to mountainous tourist areas and is characterized by winding alignments, steep ascents, and sharp descents. These characteristics, combined with limited road width, pavement deterioration, and inadequate safety facilities, make this segment highly prone to traffic accidents. This study aims to analyze the geometric conditions of the road, evaluate their influence on accident rates, and formulate improvement recommendations to enhance road user safety. The research methodology includes surveys of existing conditions, geometric road measurements, accident analysis using the Equivalent Accident Number (EAN) and Upper Control Limit (UCL) methods, and evaluation based on the 2021 Bina Marga geometric design standards. The analysis results indicate the presence of sharp curves with small radii that generate high EAN values, namely 256 for horizontal curve 1 and 288 for horizontal curve 2. In terms of vertical alignment, the segments at STA 0+410–0+420 recorded an EAN value of 15 and STA 0+460–0+470 recorded a value of 12; both exceed the threshold and are classified as black spots. Furthermore, several segments exhibit gradients exceeding 20%, far surpassing the 10% maximum specified by the 2021 Bina Marga standard for collector roads in mountainous areas. Combined with pavement damage and insufficient warning signage, these conditions significantly increase the risk of traffic accidents. In conclusion, improvements are required through the redesign of horizontal and vertical alignments, pavement rehabilitation, and the installation of warning signs, road markings, guardrails, and street lighting. This study provides a scientific basis for road planning and safety enhancement in mountainous regions and can serve as a reference for relevant authorities in addressing road segments with similar characteristics.
