Abstract

Data from the Geological Agency, Ministry of Energy and Mineral Resources (ESDM) in 2018, Indonesia has 37 billion tons of coal with proven reserves of 20.11 billion tons and estimated reserves of 17.02 billion tons. The total reserves increased by 12 billion tons compared to the previous year. To increase production and reserve coal, it is necessary to build mine roads to connect other mining areas. One of them is the work of transporting soil material for road embankment work. The constraints that are often encountered are limited resources and high cost of equipment. Therefore it is necessary to optimize the need for heavy equipment using Quantitative Methods Software (QM) for Windows V5. The data used in this study are primary data taken from the interview process and data in the form of related secondary documents, namely the RAB, Scheduling, SPK and other documents. The tools that will be used and optimized are a lot of digging and loading equipment such as Excavator PC400 with a bucket capacity of 2.6 m3, Excavator PC300 with a bucket capacity of 1.8 m3, Excavator with a bucket capacity of 0.8 m3 and a Dump Truck with a body capacity of 22.3 m3 as transportation equipment. The results of the research data analysis show that the most optimal number of tools needed for the road works is 1 PC300 Excavator unit, 1 PC200 unit and 3 Dump Truck (ADT) units for a work volume of 99.626 m3 and the optimal work duration is 814 hours and the labor cost is Rp. 2,781,227,681.

Abstract

Measurement of half cell potential is commonly used for the assessment of the resistance of reinforced concrete where corrosion of the reinforcement is predicted. The standards used in the test are ASTM C876-91: Standard Test method for half-Cell Potential of Uncoated Reinforcing Steel in Concrete and ACI 222R-01: Protection of Metal in Concrete Against Corrosion. Furthermore, the carbonation of the reinforcement in the concrete which is caused by a chemical reaction between calcium in the concrete and sulfate salts from the outside make the concrete mass is pushed and broken. The results of testing the reinforced concrete structures of office buildings on the Ancol waterfront, some of the carbonation that occurs has exceeded the concrete cover. The results of the Half Cell Potential test 1, 2, 6, 8, 9, and 10 show that the corrosion rate of the reinforcement in the concrete is <10% with type 3, namely "humid, chloride free concrete", where the concrete is moist and not contaminated chloride, which means that the corrosion rate of steel reinforcement in concrete is quite low. The results of the Half Cell Potential 3, 4, 5, and 7 tests show that the corrosion rate of the reinforcement is between 10% - 90% with type 4, namely "humid, carbonated concrete", where the concrete is moist and carbonated but the corrosion rate is not too high.

Abstract

At the time of seismic activity, the failure of the foundation structure will lead to building damage. When the West Pasaman 2022 earthquake occurred, PT. XYZ is constructing a feed mill tower. Since strong earthquake shocks were felt at the project location, foundation structure evaluation is needed to ensure the safety of the building. Ground Penetrating Radar (GPR) is a tool that is widely used to detect subsurface conditions. This study used GPR as a non-destructive testing technique to evaluate the condition of the foundation structure. The building evaluated is a high-rise steel building, using spun pile foundation. GPR test was carried out in specified lanes, with measurement tracks set at 10 lanes. Any cracks or fractures on the foundation will be indicated by the interruption of waves at the point of the crack or fracture. The GPR test results from readings of electromagnetic wave propagation showed that waves can reach the end of each foundation tested, ranging from 17.10 m to 17.82 m deep. It means that there are no cracks or fractures found on the slab, pile cap, or foundation. Analysis results showed that all slabs and pile caps thicknesses and the detected foundation piles depths are in accordance with the foundation design, which means that the foundations are still in good condition.

Abstract

A silo is a structure used to store bulk materials (bulk materials). Silos are generally used in agriculture as storage for grains and animal feed. The foundation silo must be designed to withstand the forces generated and accommodate the movements transmitted to the structure and foundation by the seismic ground motion design. The dynamic properties of the soil, the anticipated ground motion, the design basis for the strength and energy dissipation capacity of the structure, and the dynamic characteristics of the soil should be included in determining the foundation design criteria. In PT X, SILO structure serves as a place for livestock feed production, with the hope that it can last for a relatively long time. The condition of the existing SILO structure is currently some cracks in several parts of the piles and the bottom slab. The results of the visual inspection in the field regarding the condition and level of cracking in the silo foundation were compiled into a matrix inspection table using four categories: category 1 indicates no repairs needed, category 2 marked in green, represents an acceptable cracking condition with minor repairs, category 3 marked in yellow indicates moderate cracking that requires attention, and category 4 marked in red signifies major cracking or unacceptable conditions that require structural repairs. The results of the field inspection indicate that approximately 57% of the concrete slab foundation of the silo requires needs attention or repair. The condition of the plate/slab structure has some cracks measuring 0.3mm - 0.5mm, but injection and patching have been carried out. As for the condition of the silo foundation, about 30% requires needs attention and repair as well.

Abstract

In the implementation of a construction project, it is not uncommon for many obstacles to arise during its continuity, resulting in one of the common impacts, namely cost overrun. Referring to some of the problems that arise, it is calculated that there is a cost overrun of around 30% of the initial value. This research uses quantitative research methods by collecting data and distributing questionnaires. After that, some data was tested with the help of SPSS and the analysis method, namely the Relative Importance Index, to process the data. Based on the analysis carried out, the top 5 (five) rankings were obtained sequentially related to the occurrence of cost overrun in construction projects, namely frequent delays in work with an RII score of 0,8, incomplete/inappropriate information, and data provided with a score of 0,7, slow arrival of materials during implementation with a score of 0,689, improper project scheduling with a score of 0,689, and high frequency of equipment repair with a score of 0,611, as for the control measures that can be concluded, including making written records or records of events and things that cause these factors, communicating to the employer along with the consequences that can occur, and several other control measures according to the factors faced. From the study's results, it can be concluded that this research is something new and can be beneficial and used primarily by contractors to understand and find the right solutions for toll road project work and develop for other projects that experience cost overrun.
