Akibat yang sering ditemukan dari penggunaan aplikasi konvensional terfragmentasi antara lain adanya limbah kontruksi dan keterlambatan informasi yang menyebabkan inefisiensi biaya dan waktu. Oleh karena itu, dibutuhkan suatu sistem integrasi yang dapat menjawab permasalahan tersebut. Salah satu teknologi yang telah muncul untuk menjawab permasalahan adalah Building Information Modeling (BIM). Penelitian ini dilakukan dengan simulasi pemodelan dan perhitungan untuk mengevaluasi akurasi dan efisiensi biaya penggunaan aplikasi BIM 5D dibandingkan dengan metode konvensional pada pekerjaan besi dan beton. Simulasi proyek dilakukan pada apartment 16 lantai. Hasil penelitian ini menunjukkan penggunaan aplikasi BIM 5D dapat mengurangi biaya tenaga kerja sebesar Rp171.989.939,00 atau menghemat 6,33%. Nilai efisiensi volume pekerjaan beton fc30 MPa, beton fc35 MPa, dan pekerjaan besi tulangan masing-masing sebesar 7,21%, 10,87%, dan 5,98%. Total efisiensi biaya yang didapatkan sebesar Rp406.697.000,00. Biaya tersebut sangat besar dibandingkan biaya investasi aplikasi BIM 5D seharga Rp127.000.000,00. Kata kunci: Aplikasi BIM 5D, Building Information Modeling, Efisiensi Biaya Abstract Most construction companies in Indonesia currently still use conventional applications that are carried out separately. The consequences that are often found from the use of fragmented conventional applications include construction waste and delays in the information that cause cost and time inefficiencies. Therefore, an integrated system is needed to answer these problems. One technology that has emerged to answer these problems is Building Information Modeling (BIM). This research was conducted by modeling simulations and calculations to evaluate the accuracy and cost-efficiency of using the BIM 5D application compared to conventional methods in rebar and concrete work. The project simulation was carried out on a 16-floor apartment. As a result, the use of the BIM 5D application can reduce labor costs by Rp171,989,939.00 or save 6.33%. The efficiency values of fc'30 MPa concrete work, fc'35 MPa concrete, and rebar work are 7.21%, 10.87%, and 5.98%, respectively. The total cost-efficiency obtained is Rp406,697,000.00. This cost is huge compared to the investment cost of the BIM 5D application for Rp127,000,000.00. Keywords: BIM 5D application, Building Information Modeling, Cost Efficiency

Abstract

The Palabuhanratu Subdistrict, located in the Sukabumi Regency, is a high-risk area for tsunami disasters owing to tectonic activity along the Indo-Australian and Eurasian Plate subduction zones. The tsunami vulnerability level in this subdistrict is further heightened by the relatively dense population in its coastal areas, which increases the potential for loss of life and material losses. Therefore, an analysis of tsunami vulnerability levels and the planning of structural mitigation measures—such as shelters and evacuation routes—are crucial to protect communities from tsunami threats. This study aims to analyse the inundation area and affected population under tsunami scenarios with wave heights of 10, 15, and 20 m; identify the coverage of the proposed tsunami shelters; and evaluate the effectiveness of evacuation routes leading to the shelters in the Palabuhanratu Subdistrict. The methods employed include scoring and weighting techniques, Model Builder tools, and Network Analyst. The results indicate that coastal villages, such as Citepus, Jayanti, and Palabuhanratu, are highly vulnerable to tsunamis. Based on inundation modelling, Palabuhanratu Village had the largest inundated area and the highest number of affected residents. Most residents of Citepus and Jayanti Villages are located more than 1,350 m from the nearest shelter, with travel times exceeding 30 min. In contrast, the majority of residents in Palabuhanratu Village can reach shelters within 20 min, although some are still categorised as being in distant and very distant zones. A total of 11 evacuation routes were designed to connect the initial evacuation points to the shelters. However, 2 of the 11 routes, from Point 5 and 6, still exceed 1.000 m in distance and require more than 20 min of travel time.

Abstract

Indonesia has a diverse topography characterized by many hilly and mountainous regions, rendering it vulnerable to landslides. BNPB data indicate that, in 2024, there were 207 landslide incidents in Indonesia. Soil bioengineering methods using vetiver plants can improve soil stability. This study aimed to evaluate the effectiveness of vetiver application via a modular soil stabilization system using soil bioengineering. The research was conducted by testing soil properties, followed by planting vetiver in 10-cm-diameter pipes 50 cm high, with a geotextile measuring 10 × 10 × 10 cm on top containing a mixture of soil and planting media. Subsequently, maintenance, soil shear strength testing, and root dimension observations were performed on samples aged 1, 2, and 3 months after planting (MAP). The test results showed that the root growth rate increased by 30–40 cm in vetiver samples in the modular system. The most significant increase in soil shear strength was observed in the cohesion parameter, reaching 19.55 kPa. Therefore, vetiver roots contributed to the greatest increase in cohesion (c), reaching 8.57 kPa. The application of vetiver significantly increases soil shear strength, making it suitable for use as a slope reinforcement method.

Abstract

Sand has low bearing capacity due to its low shear strength and lack of cohesion. Chemical improvement is more effective than physical methods for reinforcing sand, as it does not require heavy equipment. Enzyme-Mediated Calcite Precipitation (EMCP) is a chemical method that uses pure urease enzyme, but it is not economical for field applications. Therefore, the Soybean Crude Urease Calcite Precipitation (SCU-CP) method, which substitutes pure urease with soybeans, is used as a solution. This study applies SCU-CP to reinforce sand at both laboratory and field scales using Cone Penetration Test (CPT) and Unconfined Compression Strength (UCS), with variations of 1, 2, and 3 pore volumes (PV). The study began with testing sand parameters, including gradation, specific gravity, and void ratio. Treated sand samples were tested using CPT and UCS at both scales. Calcite quantification was conducted to determine the amount and distribution of calcite formed. The results show that SCU-CP increased qc values in coarse and fine sand in the CPT test, with the highest values at 3 PV being 1.28 MPa and 2.01 MPa, respectively. Laboratory UCS tests showed maximum values at 3 PV of 331.13 kPa for coarse sand and 104.38 kPa for fine sand. Field UCS tests showed values of 193.19 kPa for coarse sand and 210.84 kPa for fine sand. Calcite distribution was uniform, with actual calcite content reaching 27.66 - 34.10% of the theoretical mass.
