Abstract

The bored pile foundation must pay attention to the safety limit to withstand the load, for this reason it is necessary to evaluate to determine whether the foundation is done in accordance with the initial planning, the purpose of this study is to analyze and compare how much bearing capacity and maximum load acting on the foundation pile based on the results of the Pile Driving Analyzer (PDA) test and the results of the Standard Penetration Test (SPT) method soil test. The analysis method is based on Reese and Wright with no reduction factor from the N-SPT value. Based on the Reese and Wright method, the ultimate bearing capacity Qu = 448.97 tons and the PDA test results of Ru = 335 tons and the calculation of the maximum load on the pile group based on the working load obtained results of 45.41 tons < 218.21 tons. The results of the calculation of the bearing capacity of the PDA and SPT tests show inappropriate results because the value obtained must be twice the plan value and the number of test points must comply with ASTM D-4945 standards.

Abstract

Tofu dregs waste is an organic waste with high fiber content that has the potential to be used as a soil stabilization material. This study aims to evaluate the effect of tofu dregs powder addition on the physical properties of clay soil, especially in the context of geotechnics and infrastructure construction. The experimental method was conducted by mixing clay soil with tofu bagasse waste in varying proportions of 0 percent, 20 percent, 60 percent, and 80 percent of the dry weight of the soil. Tests included moisture content, content weight, specific gravity, sieve analysis, and Atterberg limits. The results showed that the addition of 80 percent tofu waste decreased the moisture content from 78.81 percent to 26.34 percent, decreased the plasticity index from 132 percent to 0 percent, and increased the content weight from 1.53 g/cm³ to 1.56 g/cm³. These results indicate that tofu waste is able to reduce the plasticity and moisture of clay soils, thus potentially improving soil stability as a base material for construction. This research shows that tofu waste can be a sustainable alternative solution for soil stabilization in geotechnical projects.

Abstract

The construction of the Cipanas Ring Road alternative route, located in Tarogong Kaler District, Garut Regency, involves the use of heavy equipment such as excavators, bulldozers, vibrator rollers, and dump trucks for embankment work. Each piece of equipment has its own advantages, disadvantages, and capacities, which can affect both the cost and duration of each project phase. The method used in this study is quantitative, as it involves the use of numerical data and statistics for measurable data collection and analysis.The issue analyzed is to determine the productivity of heavy equipment usage and the operational rental costs of the equipment during the embankment work on the Cipanas Ring Road construction project. The goal is to assess the comparison between the planned productivity calculations of the heavy equipment and the actual results observed in the field. This is done by recalculating the productivity of the equipment using the standard formulas established by the Garut Regency Public Works and Housing Office (PUPR).By doing so, we can compare the cost and time estimates in the field with those calculated by the researcher. The research findings show that the actual costs and duration in the field were higher than those estimated in the analysis. The analytical results indicated a requirement of 24 days (4 weeks) with a cost of Rp.291,991,360.00, whereas the actual field implementation took 70 days (10 weeks) with a cost of Rp.644,000,000.00.

Abstract

Traffic safety around the school environment, especially at SDN Sukamentri 3-4-5 Garut, remains a serious challenge due to the high risk of accidents when crossing the road. This study aims to evaluate the need for implementing a Zone Safe School (ZoSS) to improve pedestrian safety, especially children. The research method involved primary data collection through direct survey on road dimension, traffic volume, side obstacles, crossing behavior, driver behavior, and vehicle speed, as well as secondary data from literature review and student count. The results of the analysis showed three main conditions that did not meet safety standards: disorderly crossing behavior, delivery behavior that paid little attention to safety, and average vehicle speeds reaching 25 Km/h in the school area, exceeding the safe limit of 20 Km/h. Based on these findings, the implementation of ZoSS is considered important to create a more orderly and safe traffic environment. This research contributes to the field of transportation management and infrastructure safety by offering solutions to reduce the risk of accidents in school areas. With the implementation of ZoSS, it is expected to improve accessibility and traffic discipline, and create a safer environment for pedestrians.

Abstract

Flooding is a natural disaster that frequently occurs in Indonesia. One of the main causes of flooding is the inability of drainage channels to convey water effectively and efficiently. One area that often experiences flooding is Kampung Nangoh, Panembong Village. The factors causing flooding in this area include low-lying topography, accumulated waste, sedimentation buildup in the channels, and inadequate drainage maintenance systems. To address flooding problems, a drainage system analysis is required. This analysis involves calculating the design flood discharge and determining channel dimensions capable of accommodating the planned discharge. The results of the study show that the design flood discharges for return periods of 2, 5, 10, 25, and 50 years using the Normal method are 14.48222 m³/s, 16.3194 m³/s, 17.2351 m³/s, 18.1285 m³/s, and 18.7163 m³/s, respectively. Using the Log Normal method, the design flood discharges are 14.4588 m³/s, 16.0149 m³/s, 17.0230 m³/s, 18.1053 m³/s, and 18.8757 m³/s, respectively. The channel dimensions capable of accommodating the design flood discharge using the Normal method for return periods of 2, 5, 10, 25, and 50 years are 2 × 1 m, 2 × 1 m, 2 × 1 m, 2.2 × 1.1 m, and 2.2 × 1.1 m, respectively. For the Log Normal method, the required channel dimensions for return periods of 2, 5, 10, 25, and 50 years are also 2 × 1 m, 2 × 1 m, 2 × 1 m, 2.2 × 1.1 m, and 2.2 × 1.1 m, respectively.

Abstract

The Cigelam Sub-watershed is located in the Cikarokrok watershed area in Cikampek Sub-district, Karawang Regency. Seasonal flooding is a concern, a fear for the local community. Hydrological analysis and reservoir design planning are emergency responses to natural disaster flooding events. The purpose of the research conducted this time was to calculate the design flood discharge of the Cigelam river, and flood control in Cikampek District. This research uses the Snyder Hydrograph method by designing the design rainfall and then testing the Chi Square distribution and the Smirnov - Kolmogorov Test. The design of the reservoir becomes the final stage of the research after the design flood discharge is obtained. The calculation obtained a maximum discharge of 1.266 m3/det and a planned flood discharge = 318.272 m3/det. The result of the calculation is the amount of design flood discharge with a 2-year return period (Q2) of the Cigelam river of 104.47 m3/det, (Q5) =161.71 m3/det, (Q10) = 199.61 m3/det, (Q25) = 247.49 m3/det, (Q50) 283.013 m3/det, (Q100) = 318.27 m3/det. The effective storage volume of the Cigelam river reservoir is 153,686.05 m3. The maximum amount of flood discharge that enters the reservoir when the Cigelam river reservoir is planned is 17.79 m3/det. This research contributes to the management of Cigelam river water resources in Cikampek District.

Abstract

Soil is a fundamental element in construction that functions as a structural support and therefore requires adequate characteristics and bearing capacity. Clay soil is known to have low bearing capacity and cohesive properties, so it often requires improvement. This study aims to determine the effect of mixing glass waste powder and gypsum on the California Bearing Ratio (CBR) value of clay soil from Bumi Cempaka Indah, Lebaksari Village, Karangpawitan District, Garut Regency, West Java. This location was selected because it is included in the planned construction of the Gedebage–Tasikmalaya–Cilacap (Getaci) Toll Road, making an assessment of soil bearing capacity necessary as part of infrastructure preparation. The research method uses an experimental approach through testing of physical properties, compaction, and unsoaked CBR on the original soil and soil mixed with glass powder (3%, 6%, and 9%) and a constant gypsum content of 8.5% by soil weight. The classification results show that the original soil belongs to group A-6 according to the AASHTO classification, indicating clay soil of fair to poor quality, and according to the USCS classification it belongs to group CL, or inorganic clay with low to medium plasticity, with an initial CBR value of 5.097%. A mixture of 3% glass powder + 8.5% gypsum increased the CBR to 7.188%. At a mixture of 6% glass powder + 8.5% gypsum, the CBR reached 12.319%, and at a mixture of 9% glass powder + 8.5% gypsum, the highest CBR value of 14.911% was recorded. This represents an increase of 192.54% compared to the original soil CBR value. The results indicate that the combination of glass waste powder and gypsum is effective in improving the bearing capacity of clay soil.

Abstract

Pemanfaatan limbah industri sebagai bahan substitusi parsial semen pada beton merupakan upaya penting dalam pengelolaan limbah. Abu limbah ampas aren, yang dihasilkan dari industri tepung aren, berpotensi digunakan sebagai bahan substitusi semen karena memiliki kandungan silika (SiO2) sebesar 27,89 persen yang dapat berperan dalam pembentukan C-S-H pada beton. Penelitian ini menggunakan metode eksperimen untuk mengevaluasi pengaruh substitusi semen dengan abu limbah ampas aren terhadap kuat lentur beton mutu K-300 (24,9 MPa). Variasi substitusi adalah 0 persen, 3 persen, 5 persen, dan 7 persen, masing-masing menggunakan 3 benda uji balok berukuran 15×15×60 cm. Pengujian dilakukan setelah beton mengalami perawatan (curing) selama 14 hari, menggunakan mesin uji lentur dua titik. Hasil penelitian menunjukkan bahwa substitusi parsial semen dengan abu limbah ampas aren menurunkan kuat lentur beton. Kuat lentur beton normal sebesar 3,23 MPa, sedangkan pada variasi 3 persen 5 persen dan 7 persen berturut-turut sebesar 2,72 MPa, 2,41 MPa, dan 2,61 MPa. Meskipun substitusi 3 persen memberikan hasil terbaik di antara variasi lainnya, nilainya tetap lebih rendah dari beton normal. Dengan demikian, substitusi abu limbah ampas aren cenderung menurunkan kuat lentur beton normal.
