Published: December 2024

As a country that continues to develop, the construction of high-rise buildings is inevitable, given the many capacities and functions of these buildings. However, considering that Indonesia is located between 4 main active plates of the world, so it is an area that is prone to earthquakes. As a result of this earthquake, it is necessary to design a structure that is stronger and more rigid in order to be able to withstand earthquake vibrations for a long time as much as possible.This research consists of designing the superstructure of a building in the seismic zone D by comparing the value of the drift ratio, displacement, and the amount of reinforcement towards variation structure model that occurs due to the response spectrum of earthquake load. The analytical method used is the response spectrum analysis method modelled on 3 building structure models.Based on the result of the design analysis carried out on all models, the dimension for beam with all models are 35 x 45 cm and 25 x 35, the column dimensions are 50 x 50 cm, the floor slab thickness is 125 mm and the shear wall thickness is 30 cm. The results for the model that has shear walls, decreased in the amount of reinforcement up to 14% in the column and 10% in the beam and decreased to 3% in the column and 6% in the beam for the bending moment. For the maximum drift ratio value, which is 10.26% in the x-direction of the shear wall structure model 2 and 6.81% in the y-direction shear wall structure model 3 and the smallest displacement value due to the load response spectrum on the placement of the shear wall is model 3, then the recommended model for structural planning in the seismic zone D is model 3.Keywords : momen frame system, dual system, seismic zone D, reinforcement, drift ratio, displacement

One of the methods used in controlling project time and costs is the earned value concept method. Earned value is a concept of calculating the cost budget by the work that has been completed. Where performance is measured is work completed at a certain time, which is assessed based on the amount of budget available on the project. For this reason, it can later be known the relationship between the physical progress achieved and the budget that has been spent.In this study, the object of research used was the Tanipah Village Environmental Road Improvement project, Mandastana District, and used existing data, namely general project data, contract value, schedule, and weekly reports. This study uses project performance analysis based on time and cost using the Earned Value Management method.The results of the data analysis obtained were that there was a delay in project work in week 1 and week 2, but scheduling performance improved so that in the following week there were no more delays and the project was completed on time. In terms of costs, in week 1 to week 7 the costs incurred exceeded the budget but in week 8 cost performance improved and in the last week the profit obtained amounted to Rp. 40,207,776.

Authors: Ramadhani M Aulia , Novitasari Novitasari 
Published: December 2024

The Liang Anggang Protection Forest is an area formed from peat soil. Peat soils have a role to play in conserving water resources, reducing flooding, preventing seawater seepage, and so on. Damage to the water system in peat soils is often caused by individual activities that are not well controlled. This is thought to have resulted in the depletion of water in peat soils, causing the soil to become dry and flammable in the dry season. The purpose of this research is to examine the rate of water infiltration in Liang Anggang Protected Forest Block 1. In this study, the method used in analyzing the infiltration rate was the Horton method by measuring the infiltration rate using a double-ring infiltrometer (turf-tec infiltrometer). According to the study's findings, the average decrease in infiltration rate of test 1 on bare or low-density land is 12.4 cm/hour, medium-density land is 2.7 cm/hour, very dense, closed, or forested land is 3.6 cm/hour, and test 2 on barren land is 2.4 cm/hour, medium density land is 2.7 cm/hour, and very dense, closed, or forested land is 4.7 cm/hour.

Published: December 2024

The Pebaungan River is one of the river sections in Pabaungan Hilir, Candi Laras Selatan District, Tapin Regency, South Kalimantan. In this river, there is a retaining wall with a slope condition. This planning is carried out by collecting the necessary data, followed by an analysis of the characteristics of the study soil. The value of the safety factor for the current conditions is then calculated by simulating the stability of the slope using the geoslope. After that, the pileslab design is calculated by taking into account the loading, reinforcement, and foundation calculations. After the pileslab was fixed, the slope stability analysis modeling was again carried out to determine the safety factor.According to the analysis's findings, the study soil's characteristics for hard soil were at a depth of 40 meters, and the safety factor for slope stability under the current circumstances was 0.947, which was not safe. The pileslab calculation takes into account standard loading and reinforcement, as well as the foundation design using a 30x30 square pile and accounting for bearing capacity, the lateral force of the pile, and settlement. After that, modeling was carried out to get the value of the overall slope safety factor after the pileslab was installed, which came out to be 1.515. Keywords: Pileslab, slope stability, settlement, bearing capacity

The drainage canal development project discussed is one of the projects undertaken by the Public Works and Spatial Planning Office of the City of Banjabaru. This drainage is located along Jalan Pramuka, North Loktabat. As a result of changes to the urban planning system in the city of Banjabaru, the work on improving the city's drainage system on the surrounding roads began. Many things cause an increase in the flow coefficient, which can trigger sedimentation in drainage channels and even runoff in the following years. The causes include the development and increasing density of the urban area of Banjarbaru and the bad habits of the people, such as throwing garbage in the canal.This research aims to redesign the drainage system in order to obtain a drainage network system that is more optimal in terms of environment, materials, and costs. This research was conducted by analyzing the design flood discharge at the location of the Banjarbaru City Urban Drainage System Development Project, calculating the existing drainage system calculation analysis, and evaluating a more optimal and economical drainage system design that could be suggested.Data analysis was carried out by hydrological analysis and hydraulic analysis. Furthermore, to process the data obtained, several calculation steps are carried out, such as processing daily rainfall data, frequency analysis, and discharge calculations. Through these calculations, the design discharge Qr 2 years is 0.0733 m3/second, Qr 5 years is 0.1075 m3/second, Qr 10 years is 0.3280 m3/second, Qr 15 years is 0.3599 m3 /second, Qr 20 Years of 0.3827 m3/second.

The location reviewed in this study is on Jalan Trans Kalimantan KM.12 Barito Kuala Regency precisely in front of the entrance direction of GIBS Junior High School, which is influenced by charity activities. This causes increased density and decreased vehicle speed, making the speed of vehicle movement slow. Therefore, it is necessary to conduct research to find out how much influence it causes. What will be analyzed is both directions because they are equally affected by charity activities with conditions when there are charity activities and when there are no charity activities, requiring data in the form of LHR data and the speed taken directly at the research site. To find out these influences used conventional methods (Greenshield, Greenberg, and Underwood). From the results of the analysis, the model selected affected by charity in the direction on Handilbakti and the direction on Marabahan is the Greenshield model, and the model selected when it is not affected by charitable donations in the direction on Handilbakti and the direction of Marabahan is the Greenshield model, In each direction from the calculation results with conditions when there is a charity activities there is a maximum volume decrease of 18.53% from the Handilbakti direction, and from the Marabahan direction by 40.26%. The maximum speed in the Handilbakti and Marabahan directions has decreased by 59.71% and 61.40%, and for maximum density in the Handilbakti and Marabahan directions there has been an increase of 30.11% and 15.07%.

Published: December 2024

Penelitian ini memiliki tujuan untuk mengeksplorasi dampak variasi arus pengelasan GMAW terhadap distorsi dan kekerasan pada material baja ST37 setelah dipanaskan pada suhu 400˚C. Hasil penelitian mengenai variasi arus dan perlakuan post heating pada suhu 400°C di daerah HAZ dan pada area Weld Metal menunjukkan perbedaan yang signifikan dalam nilai kekerasan. Perbedaan ini dipengaruhi oleh variasi arus yang diberikan; semakin tinggi arusnya, semakin besar pula pelunakan logam yang terjadi. Sebagai contoh, pada arus 100 A, nilai kekerasan tercatat sebesar 65 HRB, sedangkan pada arus 120 A, nilai tersebut turun menjadi 56,4 HRB. Di bagian Weld Metal, nilai kekerasan tertinggi terlihat pada arus 80 A (59,8 HRB), dan nilai terendah terdapat pada arus 120 A (51,1 HRB). Dari ketiga perbedaan suhu yang diberikan kepada spesimen dengan arus yang berbeda, yaitu 80 A, 100 A, dan 120 A, memiliki nilai distorsi rata-rata tertinggi pada arus 80 A (1,17 mm), diikuti oleh arus 100 A (0,85 mm), dan terendah pada arus 120 A (0,68 mm). Hasil penelitian uji distorsi ini menunjukkan bahwa perlakuan post heating sangat berpengaruh terhadap nilai distorsi pada spesimen tersebut. This study seeks to investigate the impact of varying GMAW welding currents on distortion and hardness in ST37 steel material post-heating at 400˚C. The research findings on the variations in current and post-heating treatment at 400°C in both the HAZ (Heat Affected Zone) and Weld Metal areas reveal significant differences in hardness values. These differences are attributed to variations in the current supplied; the higher the current, the greater the metal melting (softening) observed. For instance, at 100 A, the hardness value is recorded at 65 HRB, while at 120 A, it decreases to 56.4 HRB. In the Weld Metal section, the highest hardness value is observed at 80 A (59.8 HRB), and the lowest is at 120 A (51.1 HRB). Among the three different current levels (80 A, 100 A, and 120 A) applied to spesimens, the average distortion value is highest at 80 A (1.17 mm), followed by 100 A (0.85 mm), and lowest at 120 A (0.68 mm). These results underscore the significant impact of post-heating treatment on the distortion of the spesimen.
