Abstract

Abstract— In connection with efforts to control flooding problems in the Jeroan River, Teratai River, Sono River, and Maling River, in Madiun is necessary to conduct a survey and investigation. One of the recommendations in the work was the need for flood control with the Rejomulyo sluice gate. So that the Study of Investigation Design (SID) of the Rejomulyo sluice can provide a description of the benefits of the sluice gates. The geometry of the river flow in the Sono River in the existing condition with flood design Q1.05th  occurred flooding at elevation +63.64 to elevation +66.23, in the existing condition with flood design Q2th there was a flood at +64.56 to elevation +67.65. Whereas the river flow geometry in the Sono River in conditions with the presence of sluice gates and retarding basin with flood design Q2th occurred at an elevation of +63.90 to elevation +67.12. The use of retention reservoirs in the study area was effective enough to be able to cut flood peaks from 175 m3/s to 117 m3/s (2 year return period). while for annual returns, it can cut flood peaks from 70 m3/s to 48 m3/s. so the cutting ability of the peak of the flood is 30%. The duration of the peak cutting of the flood runs for 5-7 hours during the flood period. Keywords—: sluice gate; survey investigation design; flood.

Abstract

Pondok Reservoir is one of the smaller reservoirs built in Bengawan Solo River Basin, located in Kali Dero, Gandong Village, Bringin District, Ngawi District, with a puddle of 3.6 km2 and 32.9 km2 of drainage area. The total reservoir volume is 25,233 MCM and the effective dams volume is 22,333 MCM. The reservoirs are used to irrigate 3.596 Ha of irrigated rice fields which are distributed through four weirs, namely Dero weir, Sambiroto dam, Plesungan dam, and Padas dam. The results showed that selected crops were rice and maize, while to obtain maximum annual agricultural benefit benefit can be done with the initial period of planting for the first planting season is the third week of November, which has annual net benefit value of agriculture of Rp. 10,797,000,000. Through continuous water supply, the optimal planting area for each planting season is the first planting season in the third week of November with rice plant of 2877 ha and 719 ha of maize; the second growing season in the third week of March with rice plants 1216 ha and 1216 ha of maize; third planting season in the third week of July with 402 ha of corn. Percentage of planted area from available land per planting season is: first planting season is 100%, second planting season is 67,63% and planting season is 11,18%, so planting intensity is 178,8%.

Abstract

Abstract— Construction projects are a series of activities that have a time at the beginning and end time with the aim of realizing the idea into a physical form or building. Labor is one of the important resources, because often the supply is limited, both because of quality and other things. With a good workforce management impact on the completion of construction projects. But in the construction phase, contractors often experience many problems related to the construction project's labor allocation. This study uses the help of Microsoft Project 2007 application to create a network of Precedence Method Method (PDM) methods, then generate a bart chart for the preparation of a project implementation schedule or S schedule (time schedule) so that a histogram can be obtained after a leveling process is needed. The results of data analysis with a case study of the Bank Mandiri Development Project Palembang Office Building, it can be concluded leveling shows that the workforce needs are far less than previously planned. The number of planner workforce based on planner consultant data and reports is 8681 people and from the research results based on data processing the leveling process is only 7754 people. Keywords—: S curve; labour, histogram; Microsoft Project.
