Abstract

The use of Building Information Modeling (BIM) in Indonesia is still limited and not yet common. One of the benefits of Building Information Modeling (BIM) is to improve efficiency in calculating the amount of work. Quantity Take-off calculations are often done conventionally by measuring shop drawings manually, which can lead to errors due to inaccuracies and complexities in calculating the volume of work. One software that can assist in designing, simulating, and visualizing buildings is Autodesk Revit software. The calculation process is done by converting 2D Detailed Engineering Design (DED) drawings into 3D drawings using Revit 2024 software. The case study of this research is the Construction Project of the Guest House Building at the University of Riau, Pekanbaru City, Riau Province. The research process involves modeling based on references from shop drawings, followed by performing quantity take-off calculations on the building structure work. The output of the modeling shows the results of calculating the volume of concrete needed for the building structure and the quantity of steel reinforcement from the building structure. Based on the calculation results, the volume of concrete needed for the conventional method is 391.197 m3, which when multiplied by AHSP results in a total cost of Rp 762,376,997.19. Meanwhile, the total volume using Autodesk Revit 2024 is 318,213 m3 with a total cost of Rp 620,942.778,00. For the reinforcement work of the structure, the Autodesk Revit calculation results in Rp 1,952.501.845,31, while the results from the conventional method amount to Rp 3,697.279.792,12. It can be concluded that the calculation results using Building Information Modeling (BIM) method are smaller than the calculations using the conventional method.

Abstract

Drainage channels are water buildings that have an important function to channel excess water. With good drainage channels, excess water can be channeled and reduce the potential for waterlogging or flooding. Bungo Mas Tahap 1 Housing is located in Bungo Pasang Village which often experiences flooding or waterlogging due to high rainfall or long duration of rain. The problem of waterlogging in this area really needs attention because it disrupts various activities of the surrounding community and causes many losses. In addition to high rainfall, garbage and silt deposits in drainage channels are considered to be one of the causes of flooding. Therefore, it is necessary to analyze the existing drainage channels in Bungo Mas Tahap 1 Housing. The analysis process requires rainfall data for the last 10 years and the existing condition of the existing channels in the housing. One solution to assist in analyzing channels is using the Storm Water Management Model application (SWMM 5.2). After analysis of the channel, it was found that there was runoff in several channels so that the existing drainage was not effective because the dimensions of the channel were still not enough to accommodate the flow of water. Waterlogging that occurred in Bungo Mas Housing Phase 1 on the 2nd, 5th and 10th anniversary reached successive runoff peaks of 639.40 liters/s, 806.26 liters/s, and 914.87 liters/s which have been analyzed using SWMM 5.2 software.

Abstract

This study investigated the effect of waste tire crumb rubber on the damping characteristics of mortar for masonry wall applications using the free vibration method. Beam specimens measuring 500 mm × 100 mm × 100 mm were prepared with different crumb rubber contents and two particle sizes, namely passing the No. 4 (4.75 mm) and No. 8 (2.36 mm) sieves. Free vibration tests were conducted using a cantilever beam configuration with a 15 N suspended load. The acceleration responses were recorded using a piezoelectric accelerometer connected to the Dewesoft data acquisition system and analyzed using the Fast Fourier Transform (FFT) and logarithmic decrement methods to determine the natural frequency and damping ratio. The results showed that increasing the crumb rubber content enhanced the damping ratio while reducing the natural frequency of the mortar specimens. The highest damping ratio of 4.16% was obtained for the specimen containing 60% crumb rubber passing the No. 4 sieve. These findings demonstrated that waste tire crumb rubber effectively improved vibration energy dissipation and showed considerable potential as a sustainable material for enhancing the dynamic performance of masonry mortar.

Abstract

The productivity of overburden stripping is highly dependent on the productivity and work compatibility of the mechanical tools used. This research was carried out on the work load excavator (Fleet 1825) at Pit Banko Tengah A, PT Bukit Asam (Persero) Tbk. with the aim of analyzing the productivity level of the excavation and loading equipment, determining the work compatibility value (match factor), and evaluating the number of transportation equipment needs. Based on actual observations, obstacles were found in the form of piles of soil (spoil) on the side of the road and undulating transport road surface conditions. Road conditions that do not meet these standards result in narrowing of lanes, a decrease in the average speed of means of transportation, and an increase in cycle time. This study uses a quantitative method with primary data collection which includes cycle time, effective working time, and the number of  digging and loading bucket fills. The results of the analysis showed that the actual productivity of the Komatsu PC 2000-8 excavator excavator reached 914.57 BCM/Hour, while the productivity of the Komatsu HD-785 Dump Truck was 164.7 BCM/Hour. The assessment of work compatibility between 1 unit of excavation equipment and 7 units of transport equipment resulted in  a Match Factor (MF) value of 1.25. The MF value of > 1 indicates the occurrence of queues and waiting times for transportation equipment in the work area. Based on the evaluation of productivity suitability, it is recommended to reduce the number of transportation equipment from 7 units to 6 units so that the production target runs optimally and efficiently. In addition to optimizing the compatibility of digging loading and transporting equipment, it is recommended to standardize the geometry of the transport road according to regulations to minimize obstacle time.

Abstract

Padang Baru Jorong in Nagari Ganggo Hilia, Bonjol District, Pasaman Regency, is a rural settlement of approximately 30 households that is not served by a municipal water pipeline. Al-Ikhlas Mosque had relied on a shallow dug well with visually poor water quality, and the congregation had to draw water manually with a bucket because no permanent ablution facility was available. This community partnership activity aimed to provide a functional water-supply system and construct an accessible ablution facility for the mosque congregation and nearby residents. The program was implemented through field observation, coordination with local authorities and mosque managers, technical design and budgeting, procurement of materials, and 32 hours of construction work involving lecturers, students, and community members. The completed works included a water pump, a 500 L storage tank supported by a 2.5 m steel tower, PVC distribution pipes, a roofed ablution structure, and water faucets. The system conveyed water from the well to the storage tank and distributed it by gravity to the ablution points. The activity reduced the need for elderly congregants to lift water manually and improved the availability and convenience of water for worship. The project shows that a simple, community-based water installation can address basic service limitations in an unserved rural mosque

Abstract

The availability of adequate road capacity is an important factor in supporting the smooth mobility of people in urban areas. Srijaya Negara Street in Ilir Barat I District, Palembang City, is one of the strategic roads serving educational, trade, and service activities, so it has a high traffic volume, especially during peak hours. This condition has the potential to affect the performance of the road section, so an analysis of the road service level is needed. This study aims to analyze the service level of Srijaya Negara Street based on the characteristics of traffic flow and road capacity. The research method was carried out through a field survey with primary data collection in the form of traffic volume, road geometric conditions, and side obstacles. Data were analyzed by calculating traffic volume, road capacity, and degree of saturation (DS) to determine the level of road service. The analysis results show that traffic flow is dominated by motorcycles, followed by light vehicles and heavy vehicles. The value of the Degree of Saturation (DS) obtained is 0.748, so Srijaya Negara Street is included in the Level of Service (LOS) is D. This condition indicates that traffic flow is still stable, but the freedom of drivers to choose speed and perform maneuvers is starting to be limited due to increased interaction between vehicles. The high level of activity in educational and commercial areas, as well as side obstacles, are the main factors affecting road performance. Therefore, traffic management and side obstacle control are necessary to maintain and improve the level of road service in the future.

Abstract

Oil is a crucial element in supporting the structural integrity of buildings. However, the rapid development of infrastructure has led to a reduction in the availability of land with favorable soil conditions, forcing many constructions to be built on less stable soils. The clay soil in Tunggul Hitam, Padang City, has a low bearing capacity, exhibits high shrink-swell behavior, and loses stiffness when wet, which may result in damage to roads and foundation structures. To address this issue, chemical stabilization was carried out using palm shell ash as an additive. This research aims to analyze the California Bearing Ratio (CBR) value of clay soil in the Tunggul Hitam area of Padang City by incorporating palm shell ash in varying proportions of 0%, 4%, 8%, 12%, and 16%. The soil types used in this study were Organic Clayey Silt and Silty Clay (OL). The tests included determining the physical and mechanical properties of the soil, such as sieve analysis, specific gravity, plastic limit, liquid limit, and CBR value. The CBR tests were conducted after soaking the samples for four days. The results showed that the CBR value of the untreated soil (soaked, 65 blows) was 6.1%, which increased to 31.512% at a 16% mixture ratio. This 25% improvement in CBR value indicates that palm shell ash is effective as a stabilizing agent for enhancing the engineering properties of clay soil in the study area
