Putri Ananda — 2025-10-29

The proper drainage system design an important aspect in the development of healthcare facilities such as Permata Palembang Hospital. This study aims to analyze the suitability of the hospital drainage system design with applicable standards, and to evaluate the channel capacity to accommodating water discharge from the hospital and runoff from Citra Bukit Lestari Housing Area before operation. The analysis methods include calculation of statistical parameters, design rainfall distribution, distribution suitability test, rainfall intensity, peak flood discharge, and channel dimensions. The results of the analysis indicate that the initial design did not take into account the rainfall factors and design flood discharge. The evaluation of existing channel capacity shows sufficient capacity for U Ditch 1 channel, however the capacity of 3 box culvert channels and 4 box culvert channels is not enough to accommodate peak discharge. The optimization was carried out by redesigning the channel dimensions, widening the 3 box culvert channel to 550x400 mm and 4 box culvert to 1000x800 mm. This redesign results in a channel capacity that is able to accommodating design flood discharge, both under normal and extreme conditions.

The construction implementation system in the Mandala Mathika Subak Museum Revitalization project uses the cast in situ or conventional method including floor slab work. The implementation of floor slab work with the cast in situ method requires a long processing time and a lot of labor and costs incurred. In the construction of the building, the selection of work methods is very influential on the implementation time and cost. The selection of the right method will make the development efficient. One of them is the use of precast concrete such as half slab. In this study will compare conventional methods and half slab methods from the aspects of implementation time and cost, which is more profitable. The results of the comparative analysis of execution time and costs from the calculation of cast-in-situ and half-slab plates in the Revitalization Project of the Mandala Mathika Subak Museum show that using the half-slab method saves 33% in costs compared to the cast-in-situ method, with a cost difference of Rp. 552,730,037, and can accelerate the execution time of 43% or 19 days.

ANALISIS PERCEPATAN WAKTU TERHADAP BIAYA DENGAN METODE TIME COST TRADE OFF (Studi Kasus Proyek Pembangunan Gedung Islamic Center Kec. Rimbo Bujang Kab. Tebo Provinsi Jambi)

Taufiq . — 2025-10-29

Cost and time are critical factors in construction projects. Therefore, it is essential to determine the optimal cost and time by performing Crashing on activities within the critical path. The analysis begins by identifying the critical path using the Critical Path Method (CPM), followed by crashing the activities on the critical path. In this study, acceleration is achieved through three alternatives: adding 2 hours of overtime (alternative 1), increasing the workforce (alternative 2), and adding a night shift (alternative 3). The determination of the optimal cost and time is based on two key variablel cost and time utilizing Euclidean, analysis to identify the most efficient trade-off between the two.. The analysis reveals that the most optimal alternative is alternative 2 (increasing the workforce). The project's normal completion time is 210 calendar days with a cost of IDR 4,483,505,000 By applying Crashing, the project completion time is reduced to 148 calendar days, resulting in a time saving of 62 calendar days. However, this acceleration increases the cost to IDR 4,583,211,000 an additional IDR 99,705,000 Thus, alternative 2 is considered optimal compared to alternatives 1 and 3 in terms of cost and time.

Rini Utami — 2025-10-29

Muhammadiyah University of Surabaya has a high-rise building used as an office and lecture building, one of which is a 13-storey Rectorate Building equipped an elevator as its main facility. Elevators used intensively by students, staff, and lecturers simultaneously at peak times resulted in elevators high load, so elevator performance was less optimal. Lack of optimum elevator performance affects the elevator's long wait times and generates queues for elevator users. This study aims to optimize the performance of the elevator according to the SNI 03-6573-2001 standard against the initial planning of the Rectorate Building elevator. The methods of research used range from literature studies, preliminary surveys, data collection, and processing. Calculation of elevator requirements parameters using speed and capacity benchmarks according to SNI 03-6573-2001. In the initial planning of the elevator Rectorate Building, it is planned to use 2 units with a speed of 96 mpm and a capacity of 14 people (1050 kg), resulting in wait times exceeding the standard of 1–5 minutes. The optimization result that has been calculated through the parameters of the elevator requirements is recommended using 3 units at 90 mpm speed and capacity for 26 people (1800 kg) yielding a waiting time of 59 seconds from the standard (40-90 seconds). Such optimization results are in accordance with the standard proposed and can be an alternative in the planning of elevators on high-rise buildings, in particular lecture buildings.

Hendro Sutowijoyo — 2025-10-29

Subgrade soil is a crucial component of any construction project, be it roads, buildings, or bridges. Maintaining soil stability, particularly soil reinforcement, requires special attention. The clay soil at the Cangar site is fertile and located in the highlands. Laboratory soil testing is crucial for development planning in this area, as it enables the determination of soil properties and bearing capacity. To verify the maximum bearing capacity of the soil, a 20% limestone mixture was used, using the compaction modification and laboratory CBR testing methods. Test results revealed that the clay soil at the site has high plasticity. After mixing with limestone, the plasticity decreased by 11 points to level 15, classifying it as silty clay with moderate plasticity. Based on the CBR test of the original clay soil, the soil bearing capacity value was 22.4%, and after being mixed with 20% limestone, the value increased to 26.4%. In contrast, the maximum density of the original clay soil MDD was 0.99 grams/cm³; then, after being mixed with limestone, the MDD reached 1.24 grams/cm³. The distribution of grain size before being mixed with limestone was 2.02 grams of gravel, 61.03 grams of sand, and 436.95 grams of clay. After being given a limestone stabilizer, it was 37.06 grams of gravel, 123.45 grams of sand, and 339.49 grams of clay.

STUDI EKSPERIMENTAL PENGARUH PERUBAHAN NILAI KADAR AIR TANAH TERHADAP NILAI CBR (CALIFORNIA BEARING RATIO)

Ricky Yuda Pratama — 2025-10-29

Soil water content significantly influences the bearing capacity of a soil. Bearing capacity is the ability of the soil to support construction loads. In a construction project, the subgrade must be able to support the planned loads and meet the requirements for successful construction. This experimental study aimed to determine the soil type, specific gravity, plasticity index, and the effect of changes in soil water content on the CBR values of soaked and unsoaked soil from Lubuk Mumpo Village, Gunung Megang District, Muara Enim Regency. This study involved mixing native soil with mixture percentages of -10% OMC, -20% OMC, and +10% OMC, +20% OMC, to determine the CBR value. Ten soil samples were prepared for this test: 5 unsoaked and 5 soaked samples, based on SNI 1744-2012. The highest CBR values were obtained at 10.94% for the -20% soaking variation (soaked) for 4 days and 5.33% for the -20% unsoaked variation (unsoaked) compared to the original soil. These results indicate that a 20% decrease in water content below the OMC increases the CBR value, while an increase in water content above the OMC decreases the CBR value.

Nadia Vanesa Djobul — 2025-10-31

Good road construction is influenced by several resources, one of which is material. Road construction materials include aggregates and asphalt. These materials are held by service providers, namely material suppliers. Material suppliers are important in supporting road construction work in accordance with the time, cost, and quality that have been determined. These suppliers will form a network of cooperation called supply chains. A supply chain is a physical network consisting of companies that work together to provide raw materials, process them into finished goods, and deliver them to end users. Conceptually, the supply chain is built by several components, such as materials, suppliers, management, finance, transportation, weather, location, time, and the COVID-19 pandemic. This research was conducted to determine whether these components are important components in the smooth material supply chain. This research involved contractors working on road construction on Timor Island as resource persons. Data collection is done using the survey method, namely a closed questionnaire. Data processing and analysis techniques use descriptive statistical analysis with the help of SPSS software. Based on the results of the analysis, it shows that the success of road construction is built from component factors, namely materials, suppliers, management, finance, transportation, weather, location, and time. The COVID-19 pandemic is very important for the smooth supply chain of road construction materials on Timor Island.

Muhammad Djaya Bakri — 2025-11-01

Roads serve as critical infrastructure for enabling efficient, safe, and economical transportation of people and goods. Effective pavement planning must be based on methods suited to actual field conditions to ensure long-term functionality. The Road of Pantai Amal Lama, scheduled for construction in 2022, represents a new road segment requiring full construction from subgrade formation to surface layer. Given the relatively low traffic volume, the pavement design employs the Component Analysis Method outlined in SKBI 2.3.26.1987. This method primarily considers average daily traffic (ADT) and the California Bearing Ratio (CBR) of subgrade soil. Based on the analysis, the recommended layer thicknesses for a 10-year design life are: 10 cm sub-base, 20 cm base course, and 5 cm surface course. These structural dimensions form the technical basis for the road construction, aiming to ensure serviceability and durability under local conditions.
