Abstract

In line with the North Lombok Regency (KLU) government program to prioritize handling and structuring residential areas and disaster-prone areas in the Pemenang-Tanjung sub-district in 2022, it is necessary to carry out several technical studies to support the program. One of the technical studies that can be carried out is an analysis of the design flood and river capacity around the Sokong River section in Tanjung Village, which is a location that is classified as densely populated, with slums and residential areas close to the river border. This study aimed to determine the magnitude of the design flood discharge and the cross-sectional capacity of the Sokong river section. The method used in this study is a hydrological analysis using the Nakayasu Synthetic Unit Hydrograph method to determine the amount of design flood discharge for the 25-year return period (Q25th) and analysis of river cross-sectional capacity using Hec-RAS 4.1.0 software. The results of the analysis show that the Q25th that occurs along the Sokong River section is 131.32 m3/s and the simulation results use Hec-RAS 4.1.0 software. shows that the capacity of the Sokong River segment cannot accommodate the Q25th. Therefore, it is necessary to plan the arrangement of residential buildings around the border area of ​​the Sokong River by raising the elevation of the building to be free from flood inundation.

Abstract

Lateritic soils have a high rate of weathering and non-uniform shrinkage. So this land is not good for construction work. Biocementation is a method of soil improvement by using the ability of bacteria that have lived in the soil to do the MCIP (Microbial-induced Calcite Precipitation) process which is obtained from the bacterium Bacillus Subtilis. This biocementation stabilization can increase the strength of the soil by adding Bacillus Subtilis bacteria as an additive to stabilize the soil. The test was carried out to determine changes in the mechanical properties of CBR Laboratory soil, by mixing 3% bacteria into the soil to be stabilized. The results of testing the CBR value of the Soaked Laboratory with one day of culture increased 4.8-fold at the 28-day curing period and increasing the CBR value of the Soaked Laboratory of three-day culture increased up to 4.9 times the CBR value before stabilization, which was 19.5%. The results of the study with stabilization using bacteria variation of 3% one-day culture increased up to 95% and increased up to 96% in three-day culture. So that it can be used as a soil material for road foundations in class B.

Abstract

Avalanche often happened during a small crack on the slope. The increasing of crack’s propagation impact the cohesion and internal friction angle which causing the soil on the slope shrinkage on its strength to shift and this could cause the avalanche on the slope. There are several inquiries had been conducted in the laboratory to further study the effect of the crack’s propagation towards cohesion and internal friction angle. The inquiry in the laboratory conducted using fricative test equipment with variation of crack’s propagation. The soil sample that were tested was from Lok Buntar village, Banjar district, South Kalimantan within the varied crack’s propagation. The cohesion value and internal friction angle from the inquiry were analyzed using Fellinius method using slope model from avalanche restoration project at Muara Teweh - Benangin road border, East Kalimantan. The result of the inquiry from the laboratory showed that the increasing of the crack’s propagation decreased the cohesion and internal friction angle, this put the safety factor of the slope in a critical condition with crack at 60%. This research is expected to be able to contribute on the prevention of the upcoming avalanche on a similar soil type and model

Abstract

Dam failure has fatal consequences. This is especially true for the infrastructures as well as population settling around the dam. Due to this reason, operation and maintenance of dams should put special care and attention on dam safety. Unfortunately, the budget allocated for dam operation and maintenance for many dams in Indonesia is still very limited. Therefore, it is necessary to determine the priority scale of maintenance or rehabilitation of dams based on its risk classification through a risk assessment. The risk assessment conducted for this research uses the modified ICOLD method. The modified ICOLD method is based on the results of a major inspection conducted in 2019. The results showed that Manggar Dam is categorized as a medium risk dam with a total risk score of 45. Recommended actions to minimize the risk of harm to dam failure included improved operations and maintenance management, improved quality of human resources managing dams, and improved reporting management

Abstract

Pusat Grosir Cililitan (PGC) signalized intersection is one of the 67 traffic-prone locations located in DKI Jakarta Province, this is because in this intersection there are many business centers in Cililitan such as factories, malls, SMEs, markets, street vendors, and schools that operate which causes poor interchange performance. Poor interchange performance leads to queue length, delays, fuel wastage and time loss due to congestion. This research was conducted to analyze and optimize intersections using the PKJI 2014 method and the Student version of PTV Vissim Software. Based on the results of the study, the largest saturation degree (DS) value was obtained, namely 2,298 skr / hour, queue length (QL) of 130.84 meters, the largest average deviation delay (Dsimpang) of 361.65 s / skr. Meanwhile, the results of one of the optimizations of the intersection provide an alternative to the optimization of the interchange performance by changing the previously 4-phase phase to 2-phase and eliminating the movement of the right turn, and a decrease in delay to 48.85 seconds / skr and a change in the interchange performance category from LoS F to LoS E.
