Abstract

The material for the AC-WC hotmix mixture will affect the quality of the AC-WC hotmix itself. In the Bandung City area and its surroundings, materials for the AC-WC hotmix mixture are usually used which are taken from the Lagadar quarry and Baleendah quarry. Therefore, testing is carried out with the aim of comparing the quality of the material from which quarry is better between the two quarries. In addition, testing is needed on the asphalt that will be used because it will also affect the quality of the AC-WC hotmix asphalt produced, and testing is needed on the AC-WC hotmix sample itself by conducting a marshall test. Then the pavement thickness calculation is carried out using the AASTHO 1993 method to determine the thickness of the flexible pavement. Based on the results of the tests that have been carried out on the AC-WC hotmix mixture material taken from the two quarries, the results are quite good, both meet the required specifications. In addition, the test results on the 60/70 pen asphalt used also showed good results because all test results carried out met the specifications according to the existing SNI. The results of the marshall test on the two AC-WC hotmix samples produced showed good results. All marshall parameters for the two samples met the required specifications, but of the two AC-WC hotmix samples, the AC-WC hotmix sample with mixed material from the Baleendah quarry had better marshall parameter values.

Abstract

The need for inadequate water can have a negative impact on health and social conditions. This is also accompanied by an increase in problems related to the quality, quantity and continuity of raw water that can be used as clean water. One area that requires special attention in terms of providing raw water is Nusa Penida Island. The method used in research is quantitative. For the basis of taking drinking water needs based on the increase in existing drinking water needs and hydraulic analysis using the Epanet application. For this reason, optimization needs to be carried out to meet the demand for raw water which continues to increase along with the increasing population in Nusa Penida District. Optimizing water supply can be done by increasing the production capacity of the Penida spring water source by considering a more strategic location. Network optimization design is carried out using manual calculations and the help of the Epanet application to run simulations. Based on the analysis results, in 2038 water demand in Nusa Penida District will reach 138.15 liters/second. Production capacity is currently still experiencing a deficit of 22.52 liters/second so optimization is needed in the Drinking Water Supply System network. The addition of a pump with a capacity of 25 liters/second to the Penida spring, supported by adjustments to pipe dimensions and accessories, could be a solution to overcome the existing deficit. Rejuvenation and realignment of distribution pipes to service areas must also be carried out so that water is distributed evenly throughout the village.

Abstract

The handling of human hair waste is still not optimal, as it is often discarded or burned, leading to environmental pollution. This research aims to utilize human hair waste as a mixture in normal concrete, resulting in a fiber-reinforced concrete product with marketable value, providing a more beneficial use compared to simply being disposed of or burned. The purpose of this study is to analyze the mechanical properties of concrete using human hair fibers. The mechanical properties to be analyzed include compressive strength, tensile splitting strength, and flexural strength. This research is based on laboratory experiments. The variations in the amount of fiber used in the study are 0.25%, 0.5%, 1%, and 1.5% of the cement weight in the concrete mix. Based on the results of mechanical property testing, it can be concluded that the optimal addition of 1% human hair fibers yielded a compressive strength of 22.86 MPa, tensile splitting strength of 2.69 MPa, and flexural strength of 4.13 MPa.

Abstract

ISO or (International Organization for Standarization) is a worldwide non-governmental organization with representatives in many countries that creates and disseminates standards in the commercial, industrial and proprietary fields. The ISO organization itself was founded in Geneva, Switzerland in 1947. The construction industry in Indonesia continues to experience rapid development. The number of construction projects causes more and more construction service companies to develop and causes increasingly fierce competition between construction service companies (Contractors). Increased competition between companies makes companies aware of quality. One of the important requirements is the ownership of ISO 9001 Certificate. This study aims to determine the level of implementation of a quality management system based on ISO 9001: 2015, constraints that occur in the implementation of the ISO 9001: 2015 quality management system and strategies to improve the implementation of the ISO 9001: 2015 quality management system in the RTG Pad Manufacturing project at Perawang Port. In this study the method used is a quantitative method that is descriptive. Data is collected through questionnaires so that it is expected to obtain accurate data on the implementation of the quality management system. From the results of data analysis of the implementation of the ISO 9001: 2015 quality management system in the RTG Pad Manufacturing project at Perawang Port, it was found that the implementation level was 81.09% in the "Good" category. The obstacles faced in its application include the lack of commitment from top management being one of the reasons why the implementation of ISO 9001 is not running optimally. Strategies that companies can do to improve the implementation of the quality management system include top management maintaining consistency in implementing the principles of the ISO 9001: 2015 quality management system.

Abstract

Sea level rise due to climate change and land subsidence in coastal areas have increased the frequency of tidal flooding, especially in Indonesia. Conventional embankments that are generally used to hold back seawater have limitations in adapting to fluctuations in water levels. This study evaluates a floating fiber embankment as an innovative solution for tidal flood mitigation. The embankment is designed to automatically adapt to changes in sea level using elastic and corrosion-resistant fiber materials. Numerical simulations based on the finite element method (FEM) were performed using ANSYS software to analyze the stress, strain, and deformation of the floating fiber embankment under hydrostatic pressure. The simulation results showed a maximum stress of 8231 x 10^6 Pa with a maximum deformation of 0.43 meters. Laboratory experiments using a 1:20 scale prototype validated the simulation results, with a maximum stress of 8210 x 10^6 Pa and a maximum deformation of 0.41 meters. The results showed that the floating fiber embankment has good adaptive capabilities in resisting hydrostatic pressure and functions automatically without requiring manual intervention. This technology has the potential to be an effective and sustainable solution for tidal flood mitigation in coastal areas, especially in areas that often experience land subsidence and sea level rise due to climate change.
