Abstract

Brajan Dam is one of the dams in Karanganyar Regency. Brajan Dam has an irrigation area of 137 ha which is managed by the Gandul area. As time goes by, it is necessary to refresh appropriate planting patterns so that water needs can be met. This research aims to determine the water balance in the Brajan Irrigation Area. The method used is a quantitative descriptive method and direct observation. The analysis stage begins with exploring the irrigation network and then collecting secondary data at the research location. The secondary data was obtained from the Bengawan Solo Water Resources Development Center (BPSDA). The analysis stage is by comparing the need and availability of irrigation water. Based on the results of the analysis in the Brajan irrigation area, it was found that the annual average availability of irrigation water was 0.32 m3/second. For the maximum water requirement for Brajan irrigation, the results were 0.37 m3/second in the first month of July during the second rice planting period. For the Brajan irrigation balance, results were obtained with a water shortage value of 17% and adequate water requirements of 83%. Thus, the availability of water in the Brajan irrigation area is still sufficient to meet agricultural irrigation needs.

Abstract

This study investigates the potential of incorporating calcium carbonate (CaCO?) as a partial replacement for cement, pumice powder as a substitute for fine aggregates, and molasses as a natural retarding admixture in the development of structural lightweight concrete. The research is motivated by the growing need for sustainable, low-density construction materials that are suitable for seismic regions such as Indonesia. An experimental approach was adopted, involving laboratory testing of compressive strength and density at curing ages of 7, 14, and 28 days. The evaluation criteria were based on the Indonesian National Standard (SNI 2847:2019), which specifies a minimum compressive strength of 17.24 MPa and a maximum density of 1840 kg/m³ for structural lightweight concrete. The experimental results demonstrated that the proposed material combinations successfully met the required standards. The optimum mix composition consisted of 10% CaCO? by weight of cement, 40% pumice powder by total fine aggregate, and 0.2% molasses. Among the tested variations, the BR-40% mixture achieved a compressive strength of 27.03 MPa and a density of 1824 kg/m³, while the BR-50% mixture yielded 24.53 MPa and 1710 kg/m³, respectively. These findings confirm the feasibility of using such innovative materials to produce lightweight concrete with enhanced structural performance and improved sustainability

Abstract

Concrete is a primary construction material widely used across the world. It is a composite material composed of sand, gravel (coarse aggregate), Portland cement, and water. To improve its quality and accelerate the hardening process, additives are often incorporated. One such additive is Fosroc SP310, a type of superplasticizer. This admixture enhances concrete performance and reduces the risk of structural damage due to corrosion. This study investigates the effect of various dosages of Fosroc SP310—0.5%, 1%, 1.2%, and 1.5% by weight of cement. A total of 60 cylindrical specimens measuring 10 cm × 20 cm were prepared for compressive strength testing at curing ages of 3, 7, 14, and 28 days. The results show that normal concrete exhibited a compressive strength ranging from 24.60 MPa (14 days) to 48.44 MPa (3 days). With 0.5% admixture, strength ranged from 25.46 MPa (7 days) to 47.05 MPa (3 days). At 1%, values ranged from 23.15 MPa to 48.44 MPa. The 1.2% dosage yielded the highest strength: 54.26 MPa (14 days) and 41.80 MPa (28 days), compared to 29.71 MPa for normal concrete at 28 days. It can be concluded that the 1.2% dosage is most effective in enhancing compressive strength

Abstract

In today's developments, very rapid population growth has resulted in increasing human activities and needs, including road infrastructure. The construction of roads as infrastructure facilitates mobility and accessibility of economic, socio-cultural, and tourism activities for the community. Gemolong-Andong Highway, Central Java is a provincial road that connects Sragen Regency with Semarang Regency. Gemolong-Andong Road is a road that is heavily used by heavy vehicles such as food trucks, sand trucks, and tourist buses, including cargo vehicles that can be used in one lane and two ways. This road is 6 m wide. The activity of heavy capacity and large-sized cars also influence road conditions, so that transportation activities on roads between districts show an unbalanced development between the condition of the road structure and the road usage capacity, which causes the road to be easily damaged. Based on the observations made, it can be identified what damage occurred on the Gemolong-Andong STA 26+600-28+600 road. The problems that occur in Jalan Gemolong-Andong require research because there is a lot of damage such as holes, edge cracks, crocodile cracks, and other damage. Vehicle loads and weather factors cause the Gemolong-Andong road to disrupt road users' activities, resulting in slower vehicle travel times. Accordingly, calculations of traffic density volume and soil-bearing capacity are carried out. Then, from all the work, the total cost required is IDR 222,633,843 (Two hundred twenty-two million six hundred thirty-three thousand eight hundred and forty-three rupiah).

Abstract

This study analyses the bearing capacity of pile foundations in the construction project of the MTA Women's Boarding School Dormitory in Karanganyar Regency, Central Java. Pile foundations were chosen due to unstable soil conditions and the need for structures capable of withstanding large loads. This study combines analytical approach based on Cone Penetration Test (CPT) data with numerical simulation using Geo5 PILEGROUP software to evaluate the axial, lateral and settlement bearing capacity of the foundation. CPT data was taken from three points (S1, S2, S3) with an investigation depth of up to 13 metres. Single pile bearing capacity analyses were conducted using the Mayerhof (1976) method for axial loads and the Broms (1964) method for lateral loads. The results of the calculation obtained the largest value of S1 sondir D30 Qa = 40 tonnes, D40 Qa = 68 tonnes, and D60 = 147 tonnes. group pile analysis was carried out by considering group efficiency, distance between poles, and load distribution. The results showed that the 2-pile configuration with 3D spacing (1.8 m) was able to withstand a maximum load of 2398.135 kN, greater than the largest structural load (1582.305 kN). The pile group efficiency ranged from 0.998-1, indicating high effectiveness in distributing loads. Foundation settlement was calculated using the semi-empirical method, with the results of the largest single pile settlement of 0.6m diameter Sg = 0.022 m and pile group Sg = 0.043 m in S2 sondir data. and in geo5 software the largest settlement at D40 = 4.3 cm.
