Abstract

Drainage is a system created to overcome the problem of excess water above ground and water below ground. The performance of the drainage system is determined by using good construction techniques, carrying out routine and periodic maintenance. Heavy rains not only cause surface water runoff but also urban surface water runoff which forms puddles of water due to the low carrying capacity of the drainage system. One of the areas that experienced flooding in the city of Denpasar was Jalan Antasura in the Peguyangan Kaja area, North Denpasar, which was caused by blockage of channels by sediment caused by rubbish. This research monitors and evaluates rainfall, flood discharge and water capacity in drainage channels. The results of the calculation evaluation and comparison with HEC-RAS modeling show that the water capacity in the drainage channel at the 0-800 m point does not meet the design flood discharge results for all return periods, so it is predicted that the drainage channel will cause flooding, while the water capacity in the drainage channel at the point 800-1000 m still meets the design flood discharge at the 2 year and 5 year return periods, but does not meet the 10 year return period, so it is predicted that the drainage channel will still meet capacity if channel normalization is carried out every year.

Abstract

The Oongan Irrigation Area, which is located in East Denpasar as part of the Tukad Ayung River Basin, has a potential land area of 1781 Ha, but only 617 Ha has been utilized. In March 2019, the average discharge reached 680 l/second, while the Oongan intake gate required a discharge of 880.7 l/s for the rice growing period. Based on these data, there is a need for in-depth research in the Oongan Irrigation Area regarding the efficiency and effectiveness of irrigation canals.. The research method used is the survey method. Based on the results of the analysis of the efficiency of the primary and secondary canals and the effectiveness of the Oongan Irrigation Area, the percentage results were 80.47%, 94.1% and 35% which showed that the primary canal was not efficient and irrigation that was not effective was below the standard value, namely 90% and 55%. There needs to be an improvement both in the water management system and the physical improvement of irrigation infrastructure. Meanwhile, secondary canals get an average yield with a percentage of 94.1% which is included in the efficient category so that it needs to be maintained and carried out maintenance through operational and maintenance activities on irrigation canals.

Abstract

Soil investigations in the form of hand boring, SPT tests, and laboratories were carried out on Jalan Pura Demak Denpasar City. The purpose of this study is to determine the characteristics of the soil in the area. Handboring results showed 0 to 2.5 m of clay soil, depth of 2.5 to 3.5 m of sandy silt rock tuff, depth of 3.5 to 4 m sandy clay, depth of 4 to 10 m sandy rock. SPT test results obtained values of 12 at depths of 0 to 2.5 m, at depths of 2.5 to 3.4 m are 40 and at depths of 4 to 10 m are 43-50. Based on laboratory tests, the following soil characteristics were obtained: the moisture content at a depth of 1 m is 39.65% and at a depth of 5 m is 15.39%. Specific gravity at a depth of 1 m = 2.778, at a depth of 5 m = 2.543. Compressive strength 0.310 kg/cm2 and cohesion 0.155 kg/cm2 at a depth of 1 m. Direct shear strength at a depth of 5 m, cohesion of 0.00 kg/cm2 and shear angle of 35.30°. The results of the filter analysis for sample tests at a depth of 1 m were 80.69% clay, 13.96% silt, 5.05% fine sand, and 0.40% medium sand. At a depth of 5 m is loam + silt 29.80%, fine sand 22.47%, medium sand 25.25%, coarse sand 8.08%, and small gravel 14.39%.

Abstract

Good construction project implementation is obtained from good and detailed management. The success of project management is supported by a detailed and thorough planning and scheduling method. Project scheduling has many types with various forms, advantages and disadvantages, even in current technological developments, applications are available that can help plan, implement and control projects, namely the Microsoft Project application. In the implementation of the SDN 1 Pedungan Two-Floor Building Development project, it still uses scheduling using the conventional method (S-Curve). With the existence of various forms of scheduling, this writer compares the method between the S Curve and the Critical Path Method (CPM) to obtain effective and efficient scheduling. The data used in this study are quantitative data such as the Budget Plan (RAB) which produces job descriptions and volumes, the Time Schedule plan which produces the activity duration of each work item, the predecessor and project start time, the analysis list which produces resource requirements and the calendar. workflow that returns project start time, workdays, workhours, worktime and holidays. After comparing the duration of each work between the conventional method using the Microsoft Project 2019 application in the construction project of the Two-Floor Building at SDN 1 Pedungan, the implementation time plan is faster than the conventional method, namely with a difference of 31 days, this is influenced by calculations of needs and availability of resources. power (Unit Max) per day adjusted to the volume of work
