Abstract:
Situ Gede area includes a local protection area, functioning as a water catchment area and protected area that will be developed into an ecotourism area based on RTRW and RTBL Situ Gede area and CIFOR fiscal year 2014. The research was conducted to evaluate the existing infrastructure and to make the planning of its development special on environmental roads, waste systems, and parking buildings. The research method begins with the creation of the basic map of Situ Gede area, the retrieval of existing data using secondary data, infrastructure planning in the form of environmental roads, waste management system, and parking building planning, and the creation of infrastructure development planning map Situ Gede area as an external expected from this research. Planning to observe the conservation aspects of water resources by conducting zoning utilization. The zoning arrangement was conducted to provide protection, use, and control of existing resources, especially the creation of a lake boundary of 50 m wide from the body.

Abstract:
Estimation of evaporation rate is needed in hydrological data, especially in irrigation and drainage planning data. The method for estimating the evapotranspiration rate recommended by FAO is the Penman - Monteith method, however apart from this method there are still several methods that can be used if the data obtained in the field are different. Evaluation of the method of estimating the rate of evapotranspration is expected to help in choosing the right method when different data is obtained, so with this evaluation, we can see the accuracy of the methods. The methods that are closest to accuracy with the Penman - Monteith method are Hargreaves, Makkink, Turc, Blaney-Cridlle and Penman. If ordered based on the ranking of the evaluation results, the method that is closest to the Penman - Monteith method is Hargreaves, because of all the evaluation variabels Hargreaves has the best evaluation value. While the closest model based on the best R2 value is the Jensen-Haise model, but the error value of this model is very high.

Abstract:
Increasing of certainly development requires jobs with high productivity, effectiveness and efficiency. The application of BIM up to four-dimensional modeling (4D) using Tekla Structure software is a solution because it can analyze time performance, determine the causative factors in the event of delays and actions to overcome them. 3D modeling included modeling of foundations, columns, beams, slabs, stairs, and roofs. 4D modeling is conducted by adding work schedule to the 3D modeling that had been made. Time performance analysis was performed using the S-curve method for all buildings in Tower Green Jasmine Park Apartment Bogor construction project. Time performance analysis using the S curve found that this project experienced delays with the highest negative deviation value happened in June 2020 by -13.67%. The main delays in the project occured in procurement of MEP logistics and weather conditions. Work acceleration is carried out by increasing working hours and increasing the number of workers.

Abstract:
A review of air temperature in the Palembang city by reviewing data from the National Agency for Meteorology, Climatology, and Geophysics/BMKG (Kenten Climatology Station and the SMB II Meteorological Station) shows a difference in air temperature can indicate the occurrence of Urban Heat Island (UHI). The difference in air temperature affects the evapotranspiration rate (ET) because air temperature very influencing water evaporation. ET rate estimation with air temperature data is the first step to prove this hypothesis. Hargreaves and Samani, Blaney and Criddle, Linacre, and Kharuffa models is the ET model that using air temperature as the variable was used to estimate the ET rate. Air temperature data used in the period 2011-2020 by reviewing data from the Kenten Climatology Station and the SMB II Meteorological Station. The results of this study of air temperature data from the Kenten Climatology Station and the SMB II Meteorology Station showed a difference in air temperature with the minimum ∆T of 0.42 oC, the maximum of 0.43 oC, and the daily average of 0.41 oC. This difference in air temperature has an impact on the difference in the ET rate with the average ∆ET of the Hargreaves and Samani model of 0.05 mm/day, the Blaney and Criddle model of 0.05 mm/day, the Linacre model of 0.06 mm/day, and the Kharuffa model of 0.14 mm/day. The results of this study predicted that an increase in air temperature causes an increase in the ET rate of ± 10-30%.

Abstract:
The approach to calculating evaporation and evapotranspiration, both potential and actual, varies widely. The models used to estimate the amount of evapotranspiration, particularly at the Maros Climatology Station, Maros Regency, South Sulawesi. Evaporation models use the Penman, Priestley, Bruin, and Valiantzas models while evapotranspiration models use the Penman, Hargreaves, Jensen-Haise, Penman-Monteith, Radiation, Turc, and Makkink models, where all of these methods use climate data, such as are the minimum temperature (Tn), maximum temperature (Tx), air temperature (Ta), average humidity (RH), rainfall (R), duration of sun exposure (SS), and maximum wind speed (U) in calculations using Visual basic program in Microsoft Excel in the form of code. Thus, it is necessary to conduct an analysis of the suitability of the model to the results of the observations in order to find out which model is suitable according to the results of the largest coefficient of determination (R2). Based on the results of the model suitability analysis, a selected model was obtained, namely the Valiantzas model with a value of 0.980 in the evaporation calculation and the Jensen-Haise model, namely 0.889.

Abstract:
The effort of human creativity in the field of hydraulics in overcoming the problem of irrigation, one of which is using floodgates. The discharge from the floodgates needs to be adjusted to the water needs of the plant. However, due to the long design process, the computer aided design of sluice on tertiary irrigation channels is needed in order to be able to set the optimum dimensions and output discharges of crops water needs with fast design time. The tool used in the form of a computer device with Ms Excel and AutoCAD software and materials used were secondary data, that is water needs of local varieties of rice plants in Mangkung, Rambitan, NTB on an area of 50 ha. The data’s then calculated and the largest discharge is 0.12 m3/s with plant evapotranspiration of 5.10 mm/day and 6.43 mm/day of effective rainfall, meanwhile the smallest is 0.02 m3/s with plant evapotranspiration of 3.17 mm/day and 3.47 mm/day of effective rainfall. The dimensions of the steel sluice gates obtained are width of sluice gate 0.40 m, height of sluice gate is 0.80 m with an estimated cost of making Rp 7,547,000 per one sluice. The dimensions of the GFRP sliding sluice gates are width of sluice gate 0.50 m, height of sluice gate is 0.75 m with an estimated construction cost of Rp 7,547,000 per one sluice.
