Abstract

Rainwater was acidic water and had a pH generally ranging from pH 5.2 to 6.5. In this research using quantitative research types, where the data was obtained by conducting research in the laboratory. The sample used a cylindrical concrete with a size of 15 x 30 cm with a total of 30 specimens that will be tested for compressive strength with a Machine Compression testing machine to determine the compressive strength of concrete. The results of this study were the compressive strength of concrete using rainwater pH 5.8 and normal PDAM water pH 7.0 as a comparison. The results showed of compressive strength with water pH 7.0 at the age of 3 days 6,638 MPa, 7 days 11,878 MPa, 14 days 17,567 Mpa, 21 days 19,840 MPa and 28 days 21,490 MPa. While the results of compressive strength with rainwater pH 5.8 at the age of 3 days are 9,107 MPa, 7 days 13,830 MPa, 14 days 16,425, 21 days 16,470 and 28 days 17,982 MPa. From the results of the compressive strength above, it can be concluded that the use of rainwater pH 5.8 in concrete mixtures and curing at the age of 28 days had decreased in compressive strength by 16,32% of the compressive strength of PDAM water. Which indicates that PDAM water pH 7.0 was better for mixing concrete and curing compared to rainwater pH 5.8.

Abstract

Indonesia, as a developed country, has water-related disaster problems.Flood is one of them and it occurs in mostly province, includingBanten province. Lebak Regency as the region of Banten Province hashistory of flood occurrences. According to the Banten ProvincialBPBD (2021), among 2015-2020 period, twenty-nine flood eventsoccurred in Lebak Regency. The severest flood of that period occurredin 2020. A total 2389 residents’ homes and forty-five units of publicfacilities were damaged. Flood in Lebak regency historically alsoresulted in nine deaths, and two people were declared missing. Theobjective of this study is to be figuring out the flood risk profile andwhich districts have the highest risk in Lebak Regency by develop therisk indices map. Risk indices map informs the risk of flooding in eachsub-district, hence the policies taken can be delivered by the authorityproperly. The method used in this study used overlays based on PerkaBNPB No. 2 of 2012. This research obtains the map of the floodhazard, vulnerability, and capacity level that generates through QGIS.According to the results of the study, the risk index of Lebak district islow with three states. The sub-districts with the non-risk category areseven sub-districts with a percentage of 25%, while the sub-districtsthat fall into the slightly risky category are 10 sub-districts with apercentage of 35.7% and the sub-districts that are in the fairly riskycategory are 11 sub-districts with a percentage of 39.3%. These resultsgiven the conclusion that Lebak Regency is not considerable risk onhydrological flood events. Moderate level on vulnerability shouldgives note to the authorities to enhance the disaster resiliences.

Abstract

The Karian Dam Project is one of a total of 48 dam construction strategic projects in Indonesia that have experienced delays. Based on Addendum 6, the Karian Dam Project is targeted for completion in March 2021. However, the Karian Dam Project experienced delays in several works. This study discusses the factors of delay, the location of the risk of delay, and the work item assistance that causes delays in the Karian Dam Project. The research method used in this study is a quantitativ. Data collection was carried out using questionnaires and interviews. The obtained data is then analyzed using the Fault Tree Analysis (FTA) method to find the source of risk that is the cause of the delay. The subsequent analysis uses the Failure Mode and Effect Analysis (FMEA) method to assess the risks that have been identified using the FTA method for risk capture. According to the findings, there are 47 potential sources of delay in the FTA method. After calculating the probability index, it is found that activity A9-1 (planning and implementation) has the highest probability index value of 4. The FMEA method obtains the highest value of the highest Risk Priority Number (RPN) there is R-42 (planning change) with an RPN value of 64, and on arrest risk using the search risk matrix, as many as 9 risks are at high risk (high risk).

Abstract

This research was conducted to determine the physical and mechanical properties of origin and mixed soil with added steel slag (SS) and bamboo leaf ash (BLA) and to determine soil classification based on the Unified Soil Classification System (USCS) guidelines. This study used a mixture of steel slag and bamboo leaf ash with variations (0% SS ; 0% BLA), (20% SS; 10% BLA), (40% SS; 10% BLA), (60% SS, 10 % BLA), (100% SS; 10% BLA) with a curing time of 0 and 7 days. The mechanical properties test in this study was the unsoaked CBR test. In the USCS soil type classification system at the road location, it is included in the OH group (organic clay with high plasticity) with a plasticity index value of 22.86%, a liquid limit above 50%, which is equal to 64.5% and a DCP (Dynamic Cone Penetrometer) was obtained by 3.01%. The results showed that mixing native soil with added materials increased the CBR value. The optimum soil CBR value is found in the percentage of added material, 100% steel slag, and 10% bamboo leaf ash during seven days of curing with an unsoaked CBR value of 24.95%.

Abstract

Soft soil has high water content and low permeability, causing a high settlement and long time. Soil improvement with prefabricated Vertical Drain (PVD) can accelerate settlement in soft soils and primary consolidation time. Prefabricated Vertical Drain (PVD) functions to accelerate the release of water from the ground, and the accelerated settlement process, which is indicated by the degree of consolidation (U) reaching 90%, generally this method combines PVD and preloading (additional load). The required time to achieve a 90% degree of consolidation is determined by the PVD installation pattern (triangle pattern and rectangular pattern) and its distance. This study reviewed the effectiveness of PVD installation patterns with distance variations of (1 m, 1.3 m, 1.6 m, 1.9, 2.2 m, 2.5 m, 2.8 m, and 3.1 m). The analysis results show that in the triangular pattern, the time required to achieve a degree of consolidation of 90% (U90) is from 1 to 8.5 months, and in the rectangular pattern is from 1 to 9.5 months. The greater distance between PVDs, the more time is required to achieve a 90% degree of consolidation (U90). The PVD with a triangular pattern could reduce the 6% - 25% time to complete a degree of consolidation (U90) compared to the rectangular pattern. It can be noted that the installation triangle pattern is more effective than the rectangular installation pattern.
