Abstract

This study aims to determine the amount of deposition due to the volume of sediment mixed with solid household waste in the canal which is high enough to become shallow, resulting in a change in the geometric cross-section of the canal in the primary canal and damage to the irrigation network of D.I. Cipicung. The method used in this research activity uses a mathematical analysis technique from Chow and Grag theory in the form of sediment depth and geometric changes in the channel cross section. The results show that the volume of sediment deposited in the primary canal is Vq primary = 16.24 m3 (section length of 50.5 meters from a channel length of 300 meters) and the geometric change in the cross section of the primary channel is A = 1.24 m2. The amount of sediment volume that affects the geometric changes in the cross-section of the primary channel that needs to be repaired is that the canal linings are still alluvial with construction linings, removal of sediment that has been mixed with solid waste, and periodic maintenance.

Abstract

Consistent and efficient concrete quality in each implementation is one of the main factors in the success of construction projects. Concrete as a structural material requires strict quality control in order to meet the technical standards that have been set. One way to improve the quality of concrete is to add certain additives to the job mix formula (JMF). This research is focused on the application of SG type additives known as chemical-based additives to improve the properties of fresh concrete and hard concrete. SG additives have an important function in increasing workability, speeding up or slowing down the binding time as needed, maintaining quality stability, and strengthening concrete finishes. In this study, a comparison was made between a concrete mixture with SG additives and a concrete mixture without additives. The tests included slump parameters, initial binding time, and compressive strength at 7 and 28 days of age. The test results showed a significant difference, especially in the improvement of the consistency and compressive strength of concrete with the use of additives. The results of the discussion showed a comparison of Trial Mix 1 and Trial Mix 2 that are different in terms of material composition, cost efficiency, and compressive strength of concrete. Trial Mix 2 with the composition of cement, admixture, water, and aggregate (sand and split) showed more optimal results. The compressive strength achieved was 821,396.00 kg/cm² at the age of 28 days. In terms of cost, Trial Mix 2 requires Rp. 351,582.00 per m³, with an efficiency difference of around Rp. 32,953.00 per m³ compared to the previous mix

Abstract

Final finishing work is a critical stage in road construction because it affects surface smoothness, elevation accuracy, and road slope in accordance with technical specifications. At this stage, the motor grader serves as the primary piece of equipment; therefore, a productivity analysis is necessary to determine the effectiveness and efficiency of its use in supporting the completion of road construction projects. This study aims to analyze the productivity, equipment requirements, and operational efficiency of the Hidromek MG330 motor grader during final finishing work on the road section STA 0+400-0+500 in the Subang Smartpolitan Industrial Park, Subang Regency. The study employed a quantitative descriptive method, utilizing primary data such as cycle time, number of passes, operating speed, blade working width, pass length, effective working time, and downtime, as well as secondary data including equipment specifications, work volume, and implementation schedules. The results show that the motor grader achieved a productivity rate of 303.33 m³/hour with a daily output of 2,426.64 m³/day. A work volume of 375 m³ can be completed using one motor grader in approximately 1.24 hours, with a working time utilization rate of 15.5% and an operational efficiency factor of 75%. The results of the study indicate that the use of a single motor grader is sufficient to complete finishing work effectively and efficiently and can serve as a reference for planning heavy equipment usage, controlling project timelines, and optimizing productivity in road construction projects.

Abstract

Spillway structures serve as a vital protective element in regulating flood discharge to mitigate the risk of catastrophic dam failure. As an infrastructure featuring a distinct circular morning glory architecture, the Ir. H. Djuanda (Jatiluhur) Dam requires elevated structural safety, yet it currently undergoes cumulative concrete deterioration after exceeding five decades of operation. This study was conducted to analyze structural integrity and evaluate the maintenance management of the spillway components at Jatiluhur Dam. The methodology relies on a systematic content analysis of historical technical logs and secondary safety audit files spanning a 16-year timeline (2008–2024), quantified using a weighted Condition Index (CI) and a Failure Mode and Effects Analysis (FMEA) matrix. The evaluation reveals that the spillway's final Condition Index stands at 79.00%, indicating a marginal performance zone. Furthermore, the FMEA model indicates that the most critical operational risks are situated within the horizontal conduit and vertical shaft, both yielding a Risk Priority Number (RPN) of 32 due to visual inspection constraints. The engineering implication of this research urges dam authorities to transform routine maintenance into well-planned preventive strategies by integrating periodic non-destructive testing to detect deep-seated internal damage.
