Abstract

The rapid development of concrete technology has introduced additives that enhance and improve concrete properties. One material that can substitute cement is pozzolan, such as rice husk ash (RHA) and bentonite, which contain SiO2 and Al2O3. This study aims to examine the effect of RHA and bentonite mixtures as partial cement replacements on the compressive and flexural strength of concrete. The cement content was reduced by 5%, 10%, and 15%, and replaced with RHA and bentonite in proportions of (0%:100%), (100%:0%), and (50%:50%) for a 5% reduction, and (50%:50%) for 10% and 15% reductions. The results showed that normal concrete achieved a compressive strength of 25.29 MPa, while RHA 5% yielded 18.40 MPa, BT 5% achieved 24.44 MPa, and RHA 2.5% BT 2.5%, RHA 5% BT 5%, and RHA 7.5% BT 7.5% produced strengths of 22.27 MPa, 16.28 MPa, and 10.38 MPa, respectively. The normal concrete flexural strength was 3.73 MPa, with the optimum flexural results for RHA 5% at 4.00 MPa, BT 5% at 4.27 MPa, and the RHA 5%, BT 5% mix at 3.87 MPa.

Abstract

The high demand for concrete in construction has increased the need for concrete materials, driving the mining of rocks as a primary component of concrete. Using simple technology that utilizes local resources, including waste as building materials, is essential for concrete technology development. Candlenut shells are a new potential material due to their hard texture. This study uses a design strength of 25 MPa for normal concrete, aiming to observe the effect of using candlenut shells as a partial coarse aggregate replacement with added Silica Fume on concrete's compressive and flexural strength. The mixing method involves replacing coarse aggregate with candlenut shells in 5%, 10%, and 15% proportions. Silica Fume is added at 20% of the cement weight for concrete without candlenut shells and with shell variations at 5%, 10%, and 15%. Results show that adding candlenut shells reduces compressive and flexural strength, but adding Silica Fume enhances both strengths. Notably, the 5% candlenut shell variation with 20% Silica Fume shows higher strength than normal concrete.

Abstract

The primary causes of watershed degradation are the loss of vegetation in permanent land/forests and the inappropriate use of land. Given the current condition of the Saddang River, it is highly susceptible to flooding, especially during periods of heavy rainfall. This situation is exacerbated by changes in land use. Flooding in the Saddang watershed occurs almost annually during the rainy season, particularly in the lower reaches encompassing the districts of Duampanua, Cempa, and Patampanua. This study aims to determine the impact of land use changes on flood discharge in the lower reaches of the Saddang watershed. The research employed a quantitative approach, utilizing daily rainfall data for hydrological analysis and land cover data for land use change analysis. The Mononobe method was used to calculate rainfall intensity, while the Nakayasu Synthetic Unit Hydrograph (SUH) method was applied to compute design flood discharge. The results revealed a 7.79% change in land use between 2012 and 2021. This change led to an increase in the surface runoff coefficient (C). Consequently, there was an 8.93% increase in flood discharge during the 2012-2021 period, attributed to the higher runoff coefficient resulting from land use changes.

Abstract

The accuracy of predicting the elastic modulus of asphalt mixtures is crucial for analyzing pavement structure performance. This prediction impacts pavement responses, including tensile strain below the surface layer and compressive strain below the subgrade. Calculating equivalent standard axle loads (ESALs), specifically ESAL 4 and ESAL 5, is essential for determining pavement thickness. To ensure that flexible pavement provides safe and comfortable service, it is important to design the pavement structure to meet the planned service life. The pavement thickness was calculated using the 2017 manual pavement design method, followed by analysis with the Asphalt Institute method to predict load repetitions leading to potential road damage, such as fatigue cracking and permanent deformation. This research, a quantitative descriptive study with a case study approach, was conducted on HM. Yasin Limpo Road in Gowa Regency. The results indicated pavement layer thicknesses of 4 cm for AC-WC, 6 cm for AC-BC, 16 cm for AC-Base, and 20 cm for Class A subbase. The tensile strain value was 0.0001932 kilopascals, with load repetitions amounting to 24,324,108 ESALs, while the compressive strain was 0.0003511 kilopascals, with load repetitions of 39,924,439 ESALs.

Abstract

Currently, soil stabilization is being developed using environmentally friendly chemicals. This material is called Soil Stabilizer Solution. This research aims to analyze the characteristic and mechanical properties of soil and analyze the effect of adding soil stabilizer solution and cement on CBR values. Soil plays an important role as a supporting foundation. So from the mixing method applied to mechanical measurements on real soil, the compaction measurement uses 5 soil samples of 100% of 2kg weight without cement and SS solution, as well as the addition of 1.5% SS solution with a fixed composition using 100% soil without cement, and with the addition of 1.5% SS solution plus 4%, 6%, 8% PCC cement which reduces the soil so that the soil used is 96%, 94% and 92% of the total weight of the soil. For CBR, 3 original soil samples are used and the composition of each variation the same, with a sample weight of 5kg, the CBR value of the Original Soil is 10.22% while the increase in adding 1.5% SS Solution + 0% Cement is 18.70%, as well as the increase in adding 1.5% SS Solution + 4 %,6%,8%, experiencing an increase respectively, namely 26.85%, 31.71% and 44.79%, the use of SS solution and PCC cement for soil stabilization can increase the CBR value in the bearing capacity of clay soil.

Abstract

The Kebun Kopi - Toboli road section is a crucial route connecting several districts in Central Sulawesi. This section consists of straight roads interspersed with several sharp curves, causing inconvenience to road users. Therefore, redesigning the geometrics is essential. The objective of this research is to redesign the geometric configuration of the existing Kebun Kopi - Toboli section, from STA 10+965 to STA 11+150. This research employs a literature review method to examine applicable standards, a field survey method to obtain geometric data, and a computational model simulation using Autodesk Civil 3D software to calculate various geometric variables. The results of the horizontal alignment calculations on the existing road section, particularly on the curves, show a total length of 300 meters. The terrain classification for the proposed road is flat, with a design speed of 60 km/h and an existing road width of 2x2.5 meters. The section includes 5 Spiral-Spiral curves. For vertical alignment, there are 5 concave vertical alignments and 4 convex vertical alignments.

Abstract

Traffic problems that arise due to the activity of vehicles parked on the Bandang - North Veteran Road Agency are certainly detrimental to road users, such as when the vehicle is parked or when the vehicle leaves the park. Therefore, the aim of this research is to determine the effect of parking activities on traffic performance and road service levels around Jalan Bandang - Jalan Veteran Utara Makassar. The type of method used is a descriptive research method, where data collection is obtained from geometric surveys of roads, traffic volume, vehicle speed and parking accumulation. The results of the research show that the influence of on-street parking has on traffic performance on the Jalan Bandang - Jalan Veteran Utara section, based on the analysis results Monday, Thursday, Saturday with a DS value = 0.77 on Jalan Bandang and a DS value = 0, 93 on North Veterans Road. With a DS value > 0.75, treatment is needed to reduce density or congestion. So the level of service on Jalan Bandang is rated C, while the rating on Jalan Veteran Utara is rated E, so there must be no parking signs installed because it results in a reduction in road capacity.

Abstract

Drainage system planning is essential for the Arung Palakka Airport area in Bone Regency. The geographic conditions exhibit varied weather patterns and inconsistent rainfall, posing a risk of water accumulation that could disrupt airport operations and impact the surrounding environment negatively. Thus, effective drainage planning requires analyzing the layout systematically. This study adopts a quantitative approach in both data collection and analysis. The objective is to propose a drainage system for the Arung Palakka Airport area and determine the appropriate dimensions for the primary channel structure that align with the runoff volume in this area. Findings from this study conclude that the Type A drainage scheme channels runoff from the runway, taxiway, and apron areas, while a retention pond collects runoff from both Type A and nearby areas. Calculations show that the primary drainage channel dimensions include a freeboard height (w) of 22.5 cm, a base width (b) of 60 cm, and a wetted height (h) of 75 cm, ensuring adequate drainage capacity.

Abstract

Indonesia is a developing country with rapid progress in infrastructure and technology. Cement production requires a significant amount of energy and generates considerable waste. Innovation is essential to create construction materials that are cost-effective, energy-efficient in production, and produce minimal carbon dioxide and other hazardous waste. The use of silica fume as a partial replacement for cement, combined with paper pulp and superplasticizer in concrete mixtures, is expected to enhance concrete strength. This approach may also help reduce environmental pollution from cement production. In this study, 10% of the cement in each sample was substituted with silica fume, with paper pulp added at 0%, 3%, and 6%, and superplasticizer at 2%. The target strength for normal concrete is 25 MPa. The results show that using silica fume as a partial cement replacement can increase compressive strength by 3.36% and flexural strength by 7.24%. However, when silica fume is used with paper pulp, compressive and flexural strengths decrease. Adding both paper pulp and superplasticizer alongside silica fume results in an increase in strength, though the improvement is not significant.

Abstract

Agricultural waste such as crab shells has the potential to pollute the surrounding environment. Crab shells contain calcium carbonate (CaCO3) which will react with calcium hydroxide in cement, forming a solid compound called calcium silicate hydrate (CSH). This research examines the use of mud crab (Scylla Serrata) shell waste as a partial substitute for cement in making concrete, with the addition of a superplasticizer. The percentage of crab shells used is 0%, 10%, and 20%, as well as 2% superplasticizer. The research results showed a decrease in the compressive strength of concrete with crab shell substitution. At 10% substitution, the compressive strength decreased to 23.38 MPa, and at 20% substitution, it decreased to 16.14 MPa. The flexural strength of concrete also decreases, where 10% substitution produces a flexural strength of 3.53 MPa, and 20% substitution produces 1.60 MPa. With the addition of 2% superplasticizer, 10% crab shell substitution showed a compressive strength of 26.87 MPa, higher than normal concrete. However, at 20% substitution, the compressive strength decreased to 18.01 MPa. The flexural strength of concrete with 2% superplasticizer also decreased; 10% substitution shows a flexural strength of 3.87 MPa, higher than normal concrete, while 20% substitution decreases to 2.53 MPa.
