Abstract

This research examines the mechanical performance and durability of various mixtures of laterite material and crushed stone used in asphalt mixes. The materials used included AC 60-70 asphalt from Pertamina, coarse aggregate from crushed stone from a local quarry, laterite stone from a quarry in Central Kalimantan, and fine aggregate from a local quarry. The Marshall tests provided data on stability, flow, density, Volume of Voids in Mineral Aggregate (VMA), Volume of Voids in Mix (VIM), Volume Filled with Asphalt (VFWA), and Marshall Quotient (MQ). The Marshall test on the 100% laterite mixture showed that set A11-A13 had good density with moderate VMA and VIM values, as well as high stability and MQ. The slightly high flow indicated moderate elasticity. Set A21-A23 showed an increase in density with higher VMA and lower VIM, which improved stability but reduced MQ, indicating greater elasticity. Set A31-A33 showed a significant increase in stability and VFWA with higher flow, indicating high elasticity while remaining strong against load. Set A41-A43 had higher density and VFWA, slightly reduced stability, and lower MQ, indicating greater elasticity. Set A51-A53 had the highest density with very low VIM and high VFWA, showing very good cohesion but low stability and high flow, indicating significant elasticity and vulnerability to deformation. In the 50% laterite and 50% crushed stone mixture, set A11-A13 showed good density with moderate VMA and VIM, high stability and MQ, although the high flow indicated moderate elasticity. Set A21-A23 had increased density with higher VMA and lower VIM, resulting in better stability under load but reduced MQ, indicating increased elasticity. Set A31-A33 had significant stability and high VFWA with higher flow, indicating high elasticity but strong resistance to load. Set A41-A43 showed high density and VFWA with slightly reduced stability and low MQ, indicating greater elasticity. Set A51-A53 had the highest density with very low VIM and high VFWA, showing excellent cohesion but low stability and high flow, indicating significant elasticity and vulnerability to deformation. In the 100% crushed stone mixture, density ranged from 2.216 gr/cc to 2.232 gr/cc, indicating a dense and compact mixture. VMA increased from 16.70% to 19.04%, indicating an increased capacity of the mixture to hold asphalt, while VIM decreased from 5.91% to 4.05%, indicating increased density of the asphalt mix. VFWA increased from 64.65% to 78.72%, indicating improved pore filling by asphalt contributing to the cohesion of the mix. Stability ranged from 1,148.8 kg to 1,329.8 kg, indicating the mixture's ability to withstand deformation and load pressure. Stability was fairly high (1,117.84 kg) but lower MQ (291.602 kg/mm) indicated lower resistance to deformation compared to RA1-RA3. Set RC1-RC3 had the same density as RB1-RB3 (2.233 gr/cc), but higher VMA (11.64%) and larger VIM (4.37%), and lower VFWA (62.590%), indicating less efficient pore filling. The lowest stability (887.36 kg) and the lowest MQ (242.191 kg/mm) indicated suboptimal mechanical performance and higher vulnerability to deformation. In the abrasion test using the Los Angeles machine, laterite stone showed an abrasion value of 27.2%, indicating good resistance to abrasion and impact, suitable for construction applications requiring aggregates with high resistance to mechanical wear. Crushed stone experienced a mass loss of 30.9% after the abrasion test, still within the upper limit acceptable for road construction, but this aggregate is more prone to degradation when exposed to heavy traffic loads or extreme weather conditions. Aggregates with high wear tend to be more brittle, which can lead to a decrease in the quality and longevity of roads or structures built.

Abstract

A project is a business activity that is complex, non-routine in nature, has limited time, budget and resources and has its own specifications for the product to be produced. With the existence of several limitations in working on a project, an organization in the project is needed to manage the resources (equipment, budget, and workforce) owned so that they can carry out synchronous activities so that the project objectives can be achieved. In construction projects every building material uses concrete material, which in practice, especially in the last 10-20 years, concrete has been increasingly used. To obtain the planned concrete shape and to harden it, we need formwork or moulds. The Knowledge Hub BSD City office building project is built on an area of 1.1 hectares covering a building area of 54,956 m2 consisting of 11 floors. This location is located on Jalan Raya BSD Barat, Sampora, Cisauk District, Tangerang Regency, Banten Province. The research objective for the analysis of these calculations starts from calculating the duration of each job based on cost and time calculations obtained from existing technical drawing data. The research method used is the calculation of formwork (columns, beams and slabs) through the Microsoft Excel application.

Abstract

With the rapid development in the field of construction, various material innovations are increasingly emerging, especially in concrete. Concrete is in high demand for its durability, resistance to pressure, and low maintenance costs. Made from a growing mix of cement, coarse aggregate (split), fine aggregate (sand), water, and additives, concrete is becoming a top choice in modern infrastructure. This study aims to explore the relationship between compressive strength and flexural strength in 30 MPa quality concrete. The method used was a laboratory experiment with cylindrical and block-shaped test pieces, which were tested at the ages of 7, 14, and 28 days. The main materials used include coarse and fine aggregates, water, fly ash, and Portland type I cement. The study measured the compressive strength values of concreate, and evaluated the formula  \(fs=0.62√(fc^' ) \) as stated in SNI 2847:2013 to test its relevance to this quality concrete. The results showed that the flexural strength increased with the age of the concrete, with the largest difference between compressive strength and flexural strength at 1.3%. These findings support a deeper understanding of the performance of concrete at a given age and the relevance of the standard formula for 30 MPa quality concrete.

Abstract

The H. Rais intersection in South Tangerang City is an intersection with three arms without traffic signals. Simpang H. Rais is a meeting of three roads, namely Jl. H. Jamat Gg. Rais, Jl. Puspitek Segment 1, and Jl. Puspitek Segment 2. This intersection often experiences long queues due to inadequate intersection capacity so that it is unable to accommodate the volume of vehicles during morning and evening rush hours. The research method used was a direct survey method at the research location to collect traffic data at Simpang H. Rais and the surrounding roads. From the research results, the average length of the queue before handling during peak hours on weekdays is 168.52 m and delays are 35,471 with a level of service (LOS) D, while the average length of the queue before handling during peak hours on holidays is 119 .82 m and a delay of 33.52 with a level of service (LOS) D. In the next 5 years, the performance of Simpang H. Rais before handling will become worse with the result that the average queue length during weekday peak hours is 219.64 m and a delay of 49,137 with an intersection service level (LOS) E, while the average queue length during holiday peak hours is 218.28 m and a delay of 43,635 with an intersection service level (LOS) E. Handling is being carried out at Simpang H. Rais in short-term scenario 1 is by fulfilling road equipment facilities and assigning traffic officers, and in short-term scenario 2 by widening the bend radius to a minimum of 7.8 m and widening the H. Jamat Gg road section. Rais becomes 6 m, while the treatment carried out at Simpang H. Rais in the long term is to change the Puspitek road type to 4/2-T with a width per direction of 6 m.

Abstract

Around 15,352 families (42.66 percent) in Samosir Regency still have access to clean water, which is still a rather low percentage compared to the remaining 20,638 families (57.34 percent) who do not. The local government is concerned with this situation in order to create the BUMD PDAM Samosir Regency. This research was done to see if it would be possible to start a local water firm in Samosir Regency. In order to determine whether there is a potential water source that is adequate, sustainable, and manageable economically and profitably in the context of public services, as well as whether the establishment of PDAM Samosir Regency is worth reviewing, interviews and questionnaires were distributed to the community, SPAM owners, and State Civil Servants. In addition to socioeconomic factors, there are financial factors, market factors, legal factors, managerial factors, organizational factors, and technical factors. Legal, social and economic, technical, and notably from economic considerations with IRR = 72.32> I = 12 percent / year, PP = 3.34, and BCR = 6.27, BUMD PDAM Samosir Regency is viable to be founded
