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

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

Perkembangan manajemen proyek terus meningkat sejalan dengan perkembangan ilmu pengetahuan dan teknologi.Efektivitas pengelolaan proyek besar dapat diusahakan dengan menerapkan metode kerja yang tepat. Tahun 2021 menjadi tren bangunan precast. Struktur precast diklaim dapat menghemat 35% biaya pelaksanaan dan 27,33% lebih cepat dibandingkan dengan struktur konvensional. Hasil implementasi metode Pert pada studi kasus proyek bangunan facade precast rusunawa dapat meningkatkan efisiensi total durasi proyek sebesar 8,2 % yaitu direduksi sebesar 30 hari menjadi 335 hari. Hasil impelementasi metode parametric estimatingpada studi kasus proyek bangunan facade precast rusunawa dapat meningkatkan efisiensi biaya proyek sebesar 10,19% yaitu menjadi Rp. 34.127.000.000,-.
