<![CDATA[Self-Compacting Concrete (SCC) is an innovative solution in today's world of concrete technology. Unlike traditional concrete, it does not require a vibrator for compaction, which makes concrete work easier. One of the key features of SCC is its high workability, which is achieved through the use of chemical admixtures and mineral additives. Rice husk ash is one such additive that can be used as a pozzolanic material for concrete mixtures, which is important as rice husk waste can cause environmental problems. The objective of this study was to investigate the effect of rice husk ash on SCC concrete. The study involved using Rice Husk Ash (RHA) as a partial replacement for cement in SCC concrete at varying percentages (0%, 5%, 10%, and 15% of cement weight). The results of the slump flow test showed that the highest value of 775 mm was achieved at 15% RHA, meeting the specifications of SCC concrete. In terms of compressive strength, the results showed that the SCC mixture without rice husk ash (0% RHA) had the highest average compressive strength, which was 30.56 MPa at 14 days and 31.66 MPa at 28 days of concrete. On the other hand, the average compressive strength of SCC concrete with rice husk ash mixture was highest at 5% RHA, with 25.04 MPa at 14 days and 28.81 MPa at 28 days. Overall, the study found that the use of rice husk ash in SCC concrete had a significant effect on its compressive strength, with the highest compressive strength being achieved at 5% RHA.]]>

<![CDATA[The fire of a building will have a major impact on the building owner, both in the form of material, moral and environmental losses. In residential areas, offices and other public facilities often cause casualties. Therefore, a building needs to take into account the risk of fire so that building users can carry out activities safely and comfortably. One of the causes of fires is the fire suppression system that has not received full attention, where there is often an inadequate building fire protection system. The UNP Library Building is one of the public facilities buildings that are always crowded with students. It is necessary to evaluate the availability of the fire protection system to ensure the safety and comfort of its users. This research is in the form of an evaluation of the availability and completeness of the available fire protection systems and their remedies against the threat of fire. The data was taken through direct observation and question and answer and the distribution of questionnaires with the library. From the results of the analysis of the fire protection system inspection of the UNP Library building, it is known that on the 1st floor the lowest rediness value is 18.9%, for the 2nd and 3rd floors is 44.1%, the 4th and 5th floors are 45.9% and 45.6 % fulfilled the requirements based on the Minister of Public Works Regulation No. 26/PRT/M/2008.]]>

<![CDATA[The problem of waterlogging and surface runoff on impermeable pavement surfaces requires finding new ways to manage water flow, especially from rainwater. The type of permeable pavement that is often used is paving block. The use of paving blocks for pavement materials is expected to reduce puddles that occur after rain. One way is to modify the paving block to be greater in seeping water into the soil. This study aims to determine the extent to which the effect of adding pore holes in paving block can increase water infiltration in surrounding soil. This research was conducted through testing in the Laboratory. The type of research is quantitative with experimental method using a rain simulator tool with variations of paving block. From the research results obtained that the addition of pores in the paving block affects the infiltration that occurs. This is evidenced by the increae in the value of infiltration, the infiltration rate value of normal paving block is 182.92-10.43 mm/hour, 2% ratio is 183.75-10.75 mm/hour, 5% ratio is 190.00-11.30 mm/hour, 7% ratio is 231.33-11.46 mm/hour, 10% ratio is 236.88-17.61 mm/hour. From the test results between pore holes with infiltration rate has a significant relationship of 0.037 (<0,05).]]>

<![CDATA[Soil is the surface layer of the earth which consists of minerals, organic materials, air, living things. Clay soil is one type of soil that is important in determining the bearing capacity of subgrade required for construction. The bearing capacity of the soil is obtained by compacting it, using the TS-365 Automatic Standard Proctor. Soil compaction is the process of removing air from the pores of the soil, and is effective for improving soil properties in order to increase the density (density) of the soil so that shear strength increases, soil settlement decreases, and soil permeability decreases. The standard proctor test uses 5 separate soil samples weighing 2 kg, with a mixture of 16%, 19%, 22%, 25% and 28% air respectively. The test results show that the soil obtained from the Pojok sub-district area. Mojoroto, East Java obtained the results of soil compaction data using a standard proctor test, it was obtained that the optimum dry volume weight of the soil was 1,630 gr/cm3 and the optimum water content was 32%. So that the results of soil testing in the laboratory can be used as a reference for controlling soil compaction in construction.]]>

<![CDATA[Water is the source of life because water is not only needed by humans but also by nature to maintain a stable ecosystem. Humans and other creatures depend on water to grow and develop. The water needs of every livingthing are different and are influenced by the availability of water itself. The utilization of water as a whole in aspects of life becomes more valuable in terms of quantity and quality. The higher the cost of living for each person, the greater the need for water. This study aims to determine the projection of clean water needs in Lubuk Sikaping District from 2023 to 2043 based on population, find out the projection of clean water needs dynamically using powers studio 10 software, and find out whether the availability of clean water is sufficient for the next 20 years. The method used for the planned population projection of the next 20 years uses arithmetic methods. The results obtained in this study the need for clean water increases for the next 20 years, amounting to 125,563 liters/second. The results of water availability in Lubuk Sikaping District are still sufficient for the next 20 years. And based on the same installed capacity each year the availability of water is to be the same or constant every year.]]>

<![CDATA[Roads are a land transportation route that has been used since ancient times as a means for people to move places using existing transportation. In road construction efforts, it is necessary to have Standard Operating Procedures, or SOPs, that are used with the aim of improving worker performance, ensuring road quality, increasing profits, and company development. SOP is a method or work flow that has been standardized, is used as binding and directive instructions, and covers things from an activity that has steps or procedures. Currently, there are still many road work projects that are carried out without paying attention to existing SOPs, and this means that the quality of the concrete roads being made does not comply with applicable standards, which means that some parties may experience losses. There needs to be a good understanding of how SOPs comply with standards so that they can produce concrete of maximum quality. This writing was prepared using an analytical method using a literature study that refers to the Indonesian National Standards (SNI) and the PUPR Ministerial Regulation (Regulation of the Minister of Public Works and Public Housing).]]>
