EVALUATION OF FACTORS CAUSING DELAYS IN ROAD RECONSTRUCTION PROJECTS AND PLANNING COST AND TIME CONTROL (Case Study Of Reconstruction Project / Capacity Building Of Road Structures: Cabi-Bumi Rata R.074 Dak Regular Simpang Empat District, Banjar Regency)
Authors: Yuana Yoga Langgeng , Wardhana Henry
Published: December 2024

The implementation of the Reconstruction project/Capacity Building of Road Structures: Cabi-Bumi Rata R.074 DAK Regular Simpang Empat District, Banjar Regency in the process of its work has the potential to experience delays. As a result, there will be an increase in costs due to late fees so that time control is needed so that the project is not late with minimal costs.  This study was conducted to determine the time of delay and the cause of delay in the project by conducting an interview so that project time control can be carried out. Furthermore, the results of the interview were analyzed with the Precedence Diagram Method (PDM) whether the late work passed the critical path. Once it is known that the work is late passing the critical path in the 8th week then calculates the residual volume and duration of the remainder then put into the PDM at week 8. From the duration of the remainder is known the duration of the delay and can calculate the cost of the fine. Adding overtime and work shifts was chosen as an alternative to completing delays because with 4-hour overtime the work is still late and continued by calculating daily productivity, productivity after a crash, duration of crashes and cost increase from the two alternatives, the minimum cost of each job was chosen to obtain a duration that matches the duration of the plan with minimal costs. The results of the research that has been carried out by the project have been delayed due to natural factors that cause the Matraman bridge to be cut off and result in mobilization, procurement of materials and equipment delayed in LPA and LPB work on critical lines. Based on the analysis using PDM in the 8th week, the project experienced a delay of 33 days so that the duration increased to 173 days from the 140-day plan duration with a fine of Rp 172,766,051. Efforts that can be made to overcome these delays are by combining adding overtime for 4 hours and adding work shifts. There is an increase in costs for each activity in line with the shortened duration of the delay. The total increase was IDR 121,137,087 and the total cost was IDR 5,356,471,979. With this analysis, the project can be completed on time with a duration of 140 days, the difference in the cost of fines with crashing is IDR 51,628,964 which can be used as a graph of the relationship between cost and time based on cost increase when accelerating. Keywords: Project Delay, PDM, Cost Comparison, and Time.

ABSTRACT In planning a building construction, one of the aspects that What must beconsidered is the characteristics of the soil where the building will be erected, which willplay a role in supporting the structure.The foundation is a part of construction engineeringthat functions as a medium for channeling the load of the superstructure to the subsoilbeneath it. Types of foundations are generally divided into two categories, namely,shallow foundations and deep foundations. Shallow foundation is chosen if thecharacteristics of the soil right under the building are categorized as hard soil.In general, in the Banjarbaru area, a shallow foundation system is consideredsufficient to support the construction of buildings on it due to the characteristics of thesoil in Banjarbaru which is dominated by grainy soil types such as sand. So that inplanning the foundation of a building construction it is expected to be sufficient if usinga shallow foundation type.In terms of soil texture, in the Banjarbaru area there are 3 (three) soil texturesnamely, fine, medium and coarse. Most of the central region has a soil texture that tendsto be smooth, while a small portion in the south has a coarse soil texture.Keywords: Building construction, Soil characteristics, Shallow foundation

Early in 2021, South Kalimantan experienced a major flood disaster caused by high rain intensity. Badan Nasional Penanggulangan Bencana (BNPB) reported that as many as ten regencies/cities experienced flooding in South Kalimantan Province, one of which was Banjarbaru City. One way to reduce flooding and inundation is to have a good, economic, and appropriate drainage system. The ability of the soil to infiltrate downstream influences the design of the drainage system. Soil absorption capacity can be measured by infiltration rate experiments. This study aims to analyze the rate of infiltration in the Cempaka Slum Settlement, Cempaka District, Banjarbaru City. The data used in this study are infiltration rate measurement data collected in the field using a double-ring infiltrometer (Turf Tec Infiltrometer), which is processed using the Horton method.

Published: December 2024

Geopolymer concrete is the concrete of the future because, in its manufacture, it does not cause environmental problems; instead, it can prevent air pollution and environmental pollution. Geopolymer concrete has several advantages: suitable mechanical properties, high early strength, stable heat, and fire resistance. In the mixture, fly ash, a silicate and aluminum source, is reacted with an alkaline solution as an activator to make a polymerization reaction. To carry out the polymerization reaction, it is necessary to use Sodium Hydroxide or NaOH, which has strong basic properties as an alkaline reactant, and sodium silicate or Na2SiO3 as a catalyst.This study aims to determine the effect of using admixture on the compressive strength of 50x50x50 mm geopolymer mortar cubes. This study's ratio of the alkaline solution was 1/1, while the balance between fly ash/solution was 60/40. Planning a mixture of mortar composition, namely fine aggregate/paste of 65/35. The admixture used is Sikament LN and Sika Viscocrete 1050 HE with a curing system that is humid temperature and at room temperature. Sikament LN content is 0,3%, 1%, 1,5%, and 2% by weight of fly ash, while the Sika Viscocrete 1050 HE content is 0,8%, 1%, 1,5% and 2% by weight of fly ash. Mortar compressive strength test was carried out at 7 days, 14 days, and 28 days.In this study, the optimum grade for each use of admixture in geopolymer mortar was Sikament LN 0,3% and Sika Viscocrete 1050 HE 0,8% at humid temperature curing, which produced the highest compressive strength of 37,65 MPa and 21,26 MPa at 28 days of age. Increasing the percentage level of the amount of admixture used decreases the results of the mortar compressive strength test. The curing system shows that the mortar with the humid temperature curing system produces a higher compressive strength compared to the room temperature curing system. Keywords: Geopolymer, Fly ash, Admixture, Curing System
