Abstract

Construction made from concrete, both conventional concrete and Self Compacting Concrete (SCC), which contact with seawater, often run into decreased durability due to the content of chemical compounds that are harmful for concrete, such as Magnesium Sulfate (MgSO4) and Chloride (Cl). One way to overcome this problem is to use fine fly ash in the concrete mixture. This article discusses the results of an experimental study on the use of fine fly ash in High Volume Fly Ash- Self Compacting Concrete on durability and mechanical properties. Fine fly ash used is processed using the fly ash filtering method with a water filter. The research method is a laboratory experiment by making concrete test objects. Durability tests include Volume of Permeable Voids (VPV) and Rapid Chloride Penetration Test (RCPT), while mechanical properties is concrete compressive strength. The research results showed that using fine fly ash compared to concrete without fly ash or concrete with raw fly ash positively impacted increasing compressive strength, reducing concrete voids, and good resistance to chloride attack at low penetration levels.

Abstract

On the inside of the dam, there is a seamless instrumentation. V-Notch is one of thestandard dam safety instruments used to measure water dam seepage discharge. Theporous soil and high permeability around the V-Notch cause water seepage to notbe directed properly to the V-Notch. If it is not directed properly then the erosion ofthe reed or piping cannot be detected. So we need a construction design of thebarrier wall for collecting water seepage, namely the wall diaphragm wall. Thepurpose of this research is to analyze the material, evaluate the performance, andcompare the diaphragm wall. The method used is falling head test, monitoringobservation well (OW), direct observation method when working. The results of thedownstream wall diaphragm material permeability test using the fall head test showthat the largest permeability coefficient value is 1.3 x 10-5cm/sec. where this valuehas reached a low coefficient of permeability. Results Downstream wall diaphragmperformance based on groundwater level at OW.8 < from OW.7. Downstreamdiaphragm wall or water seepage collection barrier can be said to work well. Fromthe analysis method, the diaphragm wall is easier to work than using the Clay heapmethod. This is proven because the diaphragm wall method can be carried out in therainy season and dry season. From the time calculation analysis, it is known that itis faster to use the diaphragm method with an estimated working time of 4 months 2days using 1 tool. As for the estimated length of time working with Clay soil piles is7.5 months using 1.5 tools. Based on the calculation of the cost of drilling plasticconcrete is more expensive than the Clay heap method. The cost of diaphragm wallis Rp. 9,581,703,257.38. and the cost of Clay is Rp. 8,742,490,556.95.

Abstract

One of the infrastructures that society absolutely needs is roads. With the existence of roads, land transportation activities are carried out so that economic and social mobility runs normally. Concrete is one of the materials commonly used for road pavements, where this material technology has many advantages such as being able to withstand heavy vehicle loads and lower maintenance costs. To produce quality concrete roads, the role of the manager who leads the concrete road construction project is very decisive. To produce a quality concrete road, a manager must be able to determine indicators that influence its success, so that construction activities run effectively and efficiently. This study aims to identify Key Performance Indicators (KPIs) that can be used as a measure of success in concrete road construction projects based on the perspective of construction service providers. The analytical method used in this study is the Relative Importance Index to determine performance indicators that can be used as KPIs based on their relationship to success in concrete road construction projects. The results of the analysis show that the performance indicators that can affect the success of a concrete road construction project based on the perspective of a construction service provider are cost, quality, time, productivity, and environment, each of which has a weight of 21.41%, 19.44%, 19.05%, 15.65%, 12, 86% and 11.59%.

Abstract

Prioritizing school building maintenance solely based on structural damage often leads to inefficient budget allocation and fewer beneficiaries. The research introduced an integrated Cost-User Effectiveness Ratio (CUER) to establish maintenance priorities by combining three critical factors: damage severity, maintenance costs, and the number of affected students. The CUER formulation employed the Geometric Mean or the root mean multiplication of the cost effectiveness and user effectiveness ratio to balance these factors systematically. The methodology encompassed several steps, including damage assessment and calculation of component importance weights using the Analytical Hierarchy Process (AHP), to determine integrated damage levels, costs, and student weights. These inputs were subsequently used to generate priority rankings of schools requiring maintenance. As a result, the case study in Wonogiri Regency illustrates the superiority of the proposed method over the conventional method. While the conventional approach prioritizes 27 schools benefiting 2,442 students, the CUER approach prioritizes 33 schools benefiting 2,957 students, demonstrating increased efficiency and broader impact. The CUER-based model presents a systematic and equitable solution to prioritize school building maintenance, ensuring the optimal allocation of resources and maximizing benefits within existing budgetary constraints. This innovative approach addresses current challenges in maintenance planning and offers significant implications for improving the management of educational infrastructure.
