Abstract

Indonesia is located at the convergence of the Eurasian, Pacific, and Indo-Australian tectonic plates, making it prone to significant earthquakes, such as the Aceh earthquake and tsunami in 2004 with a magnitude of 9.1, and the Padang earthquake in 2009 with a magnitude of 7.6, both known for their severe impacts. According to the Central Statistics Agency (BPS), there were 10,843 earthquakes in 2022. Given this high level of risk, all buildings, especially offices, must be designed to be earthquake-resistant due to high activity and user numbers. The city of Padang is categorized in Seismic Design Category D, indicating a high level of earthquake risk. The construction of a ten-story reinforced concrete building for office use is planned, referring to SNI 1726-2019 on earthquake resistance and SNI 1727-2020 on minimum loads, along with the Special Moment Resisting Frame System (SMRF). Structural analysis and modeling are conducted using ETABS software, with element dimensions based on the initial design. This analysis aims to ensure the building meets earthquake resistance requirements through response spectrum evaluation, including natural periods, inter-story drift, P-Delta effects, and checks for irregularities. Based on internal forces from ETABS V.18, reinforcement designs are prepared for structural elements such as columns, beams, slabs, and shear walls. A design capacity evaluation ensures the safety and optimal performance of the structure during an earthquake.

Abstract

Indonesia is the second largest producer of plastic waste in the world after China with an annual contribution of 187.2 million tons of plastic waste. This study aims to analyze the effect of the addition of plastic seeds with polypropylene substitution on the compressive strength and flexural strength of concrete with the intention of reducing waste waste and utilizing it as a concrete mixing material and making concrete properties into green concrete. The method used is the experimental method by making several variations of concrete mixtures with plastic seeds of polypropylene type as a substitute for part of the sand. The mixing of plastic seeds is divided into several variations, namely, 3% polypropylene seeds and 6% polypropylene seeds. Analysis of the test results of the addition of polypropylene seeds compared to the concrete mixture without polypropylene seeds resulted in a compressive strength of 24.14 MPa for the addition of 3%, as well as a value of 23.25 MPa for the addition of 6% each at 28 days of concrete age. As for the flexural strength, an increase value of 0.16 MPa was obtained for the addition of 6% and the addition of 3% at the age of 28 days. This study shows that the results of the study have reached the planned quality target, namely the quality of fc'20 Mpa.

Abstract

In an era of rapid technological and infrastructural development, the quality of roads is critical to ensuring efficient and safe mobility. Composite roads, which consist of a mixture of different types of construction materials, have become an attractive option in road development in various regions. However, to ensure the success of composite roads, structural consistency and performance must be considered. A Light Weight Deflectometer (LWD) is a device used to measure the instability of road layers by applying surface pressure and measuring the resulting deflection. Although the use of LWD is common in the road construction industry, specific research on LWD consistency testing of composite roads is limited. This study investigates and analyzes the consistency of LWD on composite roads to improve the understanding of its performance. The results of the study on composite pavements conducted at three points with 30 trials showed a coefficient of variance of less than 5%. This result indicates very strong data consistency. Based on these consistency values, the LWD is acceptable, but it needs to be correlated with other tools to determine its validity. If the consistency and correlation meet the requirements or are less than 5%, LWD has a good chance of being used in composite pavements.

Abstract

Waste sludge from the Water Treatment Plant (IPA) is used as an additive in the manufacture of environmentally friendly bricks to reduce river pollution. In the process of making these bricks, clay is mixed with sewage sludge at 15% of the total weight of clay. In addition, to reduce the impact of air pollution, the bricks were not burned. This research emphasizes the importance of using environmentally friendly alternative materials in brick production. Bacillus Huizhouensis bacteria was applied to strengthen bricks with variations of bacteria concentration of 8%, as well as bacterial culture age variations of 8 hours, 10 hours, and 15 hours. After the bricks were matured for 14 days, the test results showed that bricks using 8% bacterial solution with 10 hours of culture increased by 70.65% to 1.57 MPa, compared to normal bricks of 0.92 MPa. So that bricks with 8% bacteria with a culture age of 10 hours with a period of 14 days have a higher value than normal bricks.

Abstract

In recent years, the use of unmanned aerial vehicles (UAVs) has become an alternative for topographic mapping, and this is called the UAV-Photogrammetry method. Topographic mapping in mining activities is carried out to determine the progress of actual volume of material taken. However, in general, topographic mapping is carried out using terrestrial survey methods. These methods require a long data acquisition time and a lot of personnel. This paper focuses on surveying the volume of mining progress using the UAV-Photogrammetry method and compares it with truck count volume data. The results of this study showed that the deviation in volume calculations using UAV-Photogrammetry method compared with truck count volume data in week I was 233 m3 or 0.654%, week II was 214 m3 or 0.151%, week III was 496 m3 or 0.840%, and week IV was 243 m3 or 0.210%. The results of the t-test showed that there was no significant difference between the volume calculation using the UAV-Photogrammetry method and truck count data, which means both measurement types produce statistically similar results.

Abstract

Sedimentation is the deposition of material carried by water media. The occurrence of sedimentation disrupts river flow, leading to increased susceptibility to flooding and drought during dry seasons. The impact of sedimentation causes riverbed siltation, reducing the river's capacity from its natural state. The Cariang Dam, located in Ujung Jaya Village, Ujung Jaya District, Sumedang Regency, is experiencing sedimentation issues. This has resulted in siltation and a decrease in the river's capacity at the dam site. In light of these issues, the researcher is interested in analyzing sedimentation at the Cariang Dam area. This analysis aims to determine the volume and height of sedimentation occurring annually. Based on the analysis conducted, the sedimentation height per day is found to be 0.7 centimeters, amounting to 23 centimeters per month and 276 centimeters annually.
