Abstract

Generally, Drainage could be defined as technical measures to reduce excessive water, either from rainwater, permeation, or excessive irrigation water from a region, therefore the land function not disrupted. The purpose of this study are to analyze, learn and evaluate the drain condition and capacity in the Bukit Cengkeh II Residential, Cimanggis Sub-district, Depok City specifically in blockhouse G, H and I to the flood discharge that occurred. The data and information used for this study are primary data (personal research data collected by the author) and secondary data (rainfall from BMKG and nearest Irrigation Center). Flood discharge study methods use two methods, i.e. Rational method and Hasper's method. From these two methods, we used the largest volume of the flood discharge. The results of the Flood discharge planning in block G are 2,39 m3/sec, block H are 5,42 m3/sec, and block I 1,12 m3/sec. There found 10 drains identified as runoff or unsecured. The alternative solutions to runoff or unsecured drains problems are create a new drains dimension plan or construct an infiltration well.

Abstract

The development of the capital city is very rapidly this will cause water demand will continue to increase along with the rate of population growth, all fulfillment of food needs, and activity of the population closely related to the needs of water. This research aims to determine the total number of water needs required by the Patra Jasa building in the years 2020-2025 and to conserve water use and costs with the presence of alternative water sources. This study used the research method of case study approaches with the accumulation of primary data and secondary data, subsequent analysis of the availability and water needs, and replaced with alternative water sources. From the results of this study, the consumption of clean water 63838.5 m3, non-consumptive water per year 46681 M3 with details of flushing needs 36500 m3, watering 6351 m3, and cooling tower 3650 M3. The potential of source research-alternative water sources as in this is a source of rainwater that can be used to meet the daily needs of the building of 879.38 m3/day so that it can cover all the needs of non-consumptive water. FRP tank design used is FRP tank 1200 m3 with a method of rain supply that can be harvested from the roof of Patra Jasa building is 320973.7 m3/year and the average requirement is 174.9 m3/day, 5274 m3/month, 63838.5 m3/year. Annual water uses savings of 57835.71 m3/year or Rp. 725,880,160.00.

Abstract

Wastewater in general is water, in general, is a liquid that comes from households, industries, or other public places that usually contain materials or substances that can endanger human life and disturb the environment. Quid comes from households, industries, or other public places that usually contain materials or substances that can endanger human life and disturb the environment. This study to plan, analyze, and assess the performance conditions of wastewater treatment plants (IPAL) at PT XYZ Bekasi Regency on environmental quality standards. Data and information used are data on the amount of wastewater, sources of wastewater, and behavior of water use as well as secondary data in the form of data that the authors surveyed directly at the research location. The processing method of the output value of WWTP uses the research method of the laboratories from the research method in which the output value exceeds the quality standard of LHK Regulation No. 68 the Year 2016 and has exceeded its planning capacity. And what is identified is not safe. An alternative solution to the problem of unsafe output values ??is by planning a new wastewater treatment plant.

Abstract

The foundation structure design for the construction of the SIG-2 Building uses a circular pile foundation with a diameter of 0.60 meters and a depth of 15 meters. Verification of the planned bearing capacity was carried out based on data from 2 (two) NSPT test points and continued by comparing the actual carrying capacity based on Static Loading Test (SLT) data. This research aims to compare the planned bearing capacity with the actual bearing capacity during construction, and settlement occurred. Analysis of bearing capacity calculations was carried out based on NSPT data using the Meyerhoff method, while analysis of actual bearing capacity calculations based on SLT data used the Davisson method, Chin method, and Mazurkeiwich method. Based on research conducted at 2 (two) test points, the average bearing capacity of the pile is 185.99 tons, and the average settlement (Sav) is 47.3 millimeters. The allowable settlement is 60 millimeters. The settlement on tested piles is 14,8 mm and 15,8 mm respectively. The results of the bearing capacity analysis based on actual Static Loading Test (SLT) data with a planned load of 200 tons using the Davisson method, Mazurkeiwich method, and Chin method are 179 tons, 185 tons, and 234,9 tons, respectively. Based on the upper structure loading data obtained from the structural planning report, it is concluded that the bearing capacity of the pile group is still safe and able to withstand the planned load on each column of the building structure, assuming the bearing capacity of a single pile of 179 tons, a total of 61 piles with the allowable bearing capacity of all piles of 10,809.81 tons and the building plan load of 9,066.23 tons.

Abstract

The need for irrigation water as a whole need to be known in the planning and management of irrigation systems. Given that the Cisadeng II Irrigation Area (DI) located in Leuwisadeng District, Bogor Regency, experienced an expansion of the paddy field area from 32 ha to 42 ha, it is necessary to carry out an analysis of the demand for irrigation water discharge on various cropping patterns. This study used two methods, namely manual calculation (KP-01 concept) and calculation using the CROPWAT application version 8.0. This study aims to compare the results of the two calculations. From the results of the study, the amount of irrigation water needed for rice cropping pattern with the beginning of land preparation in November, with manual calculations (KP-01 concept) using the modified Penman method is 8.12 - 19.00 m3/sec. Meanwhile, according to CROPWAT Version 8.0 calculations, it is 8.03 - 18.39 m3/sec. Thus, it can be concluded that the calculations with the two methods do not give too different values. In addition, from the results of calculating the reliable debit, the use of the CROPWAT Version 8.0 method provides a more accurate value. Keywords: Irrigation, water demand, manual calculation (KP-01), CROPWAT Version 8.0
