Abstract

The Jatingaleh BRI Regional Office is one of the buildings in Central Java that will be reconstructed. This is done to improve the function of the building with new reinforcement. One of the processes before being reconstructed is to check the compressive strength of concrete by means of a non-destructive test using a hammer test & semi destructive using a core drill. One of the factors that affect the strength of concrete is surface hardness. The method used in this study was to collect primary data in the form of hammer test results, compressive strength test results using the core drill method and secondary data obtained from the contractor. The purpose of this study is expected to be able to determine the correlation of compressive strength with the hammer test method and the core method. After carrying out the hammer test, proceed with the core drill test. Based on the research results, the compressive strength correlation was obtained using the hammer test and core drill method which is presented by an equation 𝟏.𝟑𝟏𝟕𝟖𝒆𝟎.𝟎𝟓𝟔𝟕𝒙 with a value of 𝑹𝟐=𝟎.𝟖𝟏𝟏𝟔.

Abstract

The main problems with soft clay soil are high water content, low soil mineral content, and high compressibility, so stabilization materials are needed that can increase the bearing capacity of soft soil. In this research, the urease enzyme was used as a catalyst to increase the bearing capacity of the soil. The material used is organic material, namely soybean powder. The stabilization materials used are urea (CHâ‚„Nâ‚‚O), calcium chloride (CaCl2), and soybean powder (urease enzyme), which will form a lime compound so that it functions as a catalyst for adhesive in stabilizing soft soil. This research aims to improve soft soil by stabilizing it using the SICP (Soybean Induced Calcite Precipitation) method. The variations in urea and CaCl2 concentrations used were 1 mol/L, 2 mol/L, 3 mol/L, 4 mol/L, and 5 mol/L. The soybean extract concentrate used was 30% with a curing time of 7 days. The most optimal test result and what is used is 3 mol/L. This is in line with the SEM and XRD test results. Test specimens were made and cured for 7, 14, 21, and 28 days and then tested for unconfined compressive strength (UCS) to determine the effect of adding calcium carbonat on soil strength. The UCS test shows that the optimum shear strength value of soil cemented with calcium carbonat is produced in a curring period of 14 days is 1.02 kg/cm2. Meanwhile, for a curring period of more than 14 days, the increase in the unconfined compressive strength value is relatively very small. The increase in soil compressive strength after stabilization was 30.77%. The compressive strength value of the soil increases due to the presence of calcium carbonat formed between the soil grains.

Abstract

This research aims to analyze traffic characteristics and their impact on the level ofservice on Jalan Jenderal Gatot Subroto in Pacitan Regency. This road section isone of the important arteries that connects various areas in Pacitan Regency, andhas a big influence on mobility and the local economy. The research methodinvolves collecting traffic data through direct observation, traffic volume surveys,and measuring vehicle speeds during peak and off-peak hours. The collected datawas analyzed using road capacity analysis methods and traffic simulation models toassess the level of service (LOS) on the road section. The results of the researchshow that the characteristic pattern of Jalan Gatot Subroto, vehicle volume isdominated by motorbikes on holidays or weekends with a maximum volume of200.06 cur/hour with a maximum average speed of 31.52 cur/hour at monitoringpoint 2 which is in front of the Bus Terminal. Pacitan with the level of serviceadapted to Jalan Jenderal Gatot Subroto Pacitan from the four points surveyed was2.35, which was obtained at point 2 with a service level of D with a flow dominatedby motorbikes towards the beach tourist attraction at a stable and tolerable speed.These findings provide important insights for traffic planning and management, aswell as recommendations for infrastructure improvements to increase trafficefficiency and safety in the region.

Abstract

Local scour is the erosion of soil at the riverbed, often occurring due to changes inflow type that become concentrated, influenced by river morphology or the presenceof structures within the river. The hydraulic jump caused by flood discharge at thegroundsill structure of the Gung River leads to local scour downstream of thestructure. Insufficient mitigation of local scour downstream of the groundsill canresult in long-term damage to the structure itself. This study was conducted toanalyze the potential scour depth using empirical methods and modeling with HECRASsoftware. The analysis considers rainfall data over the past five years in theGung River Watershed (DAS) and soil particle diameters obtained from soilinvestigations in 2022. The analysis of scour depth, taking into account a 50-yearrainfall event and followed by flood discharge analysis for a 50-year return period(Q50), yielded a design discharge for analyzing local scour depth using the Laceymethod, with a depth of 7.95 m. Through modeling with HEC-RAS version 6.5, theresulting local scour depth was found to be 8.2 m.

Abstract

Clean water is often a major obstacle, the Rempak Village Community, Siak Districtuses water from rivers and shallow wells in their daily lives. However, the waterquality is not suitable for consumption as clean water for household scale. Theamount of rainwater for clean water needs on 2 types of gable and pyramid roofs.The method used is the Rational Model to find the amount of rainwater dischargethrough rainwater catchment. The rainfall data used for the study came from theHydrology Section of BWS III Sumatra with the location of the Bunga Raya (Siak)rainfall recording station from 2016 to 2022. The results of the study prove that thecontribution of rainfall during 2 years of rain with a 110m2 gable roof obtained arainfall contribution of 0.935m3 and dimensions of 0,3 × 0,135 × 0,5m, the use of a90m2 pyramid roof with a rainfall contribution of 0,765m3, the dimensions of thereservoir tank are 0,2 × 0,2 × 0,365m. The contribution of rainfall during the 5-year return period with a 110m2 gable roof is 1,122m3 with a reservoir tankdimension of 0,3 × 0,2 × 0,622m, while a 90m2 pyramid roof has a rainfallcontribution of 0.915m3 with a reservoir tank dimension of 0,2 × 0,1 × 0,635m. Theconclusion of the study is that the more different the roof type and roof area, theamount of rainwater for clean water needs is also different.

Abstract

The Winongo River is one of the rivers in the Special Region of Yogyakarta, with itssource originating from Mount Merapi. This poses various disaster risks in theWinongo River, such as flooding, debris flow, and riverbank landslides. Thisresearch focuses on analyzing disaster risks in the downstream area of the WinongoRiver, which includes the villages of Sabdodadi, Patalan, Sumbermulyo, Mulyodadi,Sidomulyo, and Donotirto. Data collection was carried out using cluster samplingand Geographic Information Systems (GIS) for each village due to the wide areacoverage. The collected data was then analyzed using the Analytical HierarchyProcess (AHP) method to determine the level of disaster risk. The results of thisstudy show that the downstream area of the Winongo River has a moderate disasterrisk level for the villages of Sabdodadi, Patalan, Sumbermulyo, and Donotirto, anda low disaster risk level for the villages of Sidomulyo and Mulyodadi. The capacityparameter significantly influences the level of disaster risk, and based on thevulnerability analysis, this is due to the presence of retaining walls on theriverbanks, which can reduce disaster risks in the Winongo River
