During vegetative growth period, sugarcane required a lot of water but decreasing afterward and minimum at ripening period. Sugarcane water requirement was calculated by radiation method and USDA (1969) method was used to determinate effective rainfall. Average of monthly actual evapotranspiration (ETa) was calculated by the available soil water index. The total of water requirement of sugarcane (1-12 month) was around 37.38 mmlmonth to 143.22 mmlmonth. The highest water requirement was found at Herlika Asriasuri; Nora H Pandjaitan

Abstract

During vegetative growth period, sugarcane required a lot of water but decreasing afterward and minimum at ripening period. Sugarcane water requirement was calculated by radiation method and USDA (1969) method was used to determinate effective rainfall. Average of monthly actual evapotranspiration (ETa) was calculated by the available soil water index. The total of water requirement of sugarcane (1-12 month) was around 37.38 mmlmonth to 143.22 mmlmonth. The highest water requirement was found at age of 4 to 9 month, while the lowest was in the ripening period. Accordingly drip irrigation should be operated at maximum water use of about 3.96 mm/day, or by sprinkle irrigation not less than 118.70 mm/mounth.

Abstract

Inmation is important to note because it is related to potentialsurface run-08 jlood, erosion, water storage of soil, and stream discharge especially during dry season. However, because the infiltration equation is valid for certain condition of the land measured, it is important to collect infltartion data on all types of soil manually. This research is mainly to evaluate constants of infltration equation formulated by Kostiakov (constants K and n) and Philip (constants C and D) in relation with initial soil water content. The measurements are on vegetated soil and bare soil.

Abstract

Chrysant plants (Chrysantemum, sp.) as a horticulture vegetation has an estetical and economical value. Irrigation system which is used for Chrysant plants in PT Tecsuco Nusasemesta's green house are sprinkle and trickle irrigations. The water supply has to be equal with the water consumption of the plants in order to get higher water use eflciency. This research tries to calculate water use eflciency of trickle and sprinkler irrigation and its irrigation cost for chrysant plants. Water economical value is higher than before, so water consumption as one of production factor have to be planned in order to get proper benefit for every comodity. One of the methods to get the higher eflciency of water use is irrigation scheduling.

Abstract

The increasing of food demand and maintaning the national food self supporting program have become the goverment concern. On the other side farm land convertion (especially in Java and Bali) into non-farm land has increased. So, as one of the solution, the goverment has opened many new farm lands outside Java. Most of them are tidal land. Tidal lands need an occurate contruction and water management system. The aim of the study is to determine the water management system for tidal irrigation land (on farming level) by controling water surface according to the cropping pattern. The location of study is Telang I tidal irrigation area, Kabupaten MusiBanyuasin, South Sumatera.

Abstract

This research tries to find a suitable material for porous lateral pipe, its mean outflow, its coefficient of uniformity and distribution of outflow along the pipe. The material that is used in this research is Parachute and Fatnatex cloth with 20 cm long.The research shows that the Famatex cloth with 8 cm circumference, gives a better performance and can be used for the further research . Besides. the bigger head is used, the faster water flow and the bigger mean outflow from the material to the ground surface.

Abstract

A micro fertigation system was designed using local components, simple and easy to build, operate and repair by farmers. Evaluation of hydraulic performances consists oflong-path size in emitters, relationship between discharge and head in emitter, head loss along the lateral, and emission uniformity. The result of the research indicated that the micro fertigation system with 0,5 mm inside diameter micro-tubing used to control the flow from outlets along laterals. The individual microtube was 0,6 m long and spaced at 0,3 m interval along laterals. The discharge was adjusted by stop valves and ranges from 0,48 -2, 74 ltrs/h at operating heads of 0,2-1,5 m. The emission exponent, x was 0,86, and the head-discharge equation was Qe= 1,94 H0,86. The coefficient of manufacturing variation, CV was 0,043 from 125 samples of emitters, and an interpretation of values was excellent. Accordingly allowable length of lateral (at operation head, H = 1 m) 15 meters of length PVC hose ¼ inch size was acceptable and 25 meters of length PVC hose 5/16 inch size was acceptable. The design of micro fertigation system have emission uniformity, EU > 85% far all treatments.  Keywords: micro fertigatian system, hydraulic performance, emission exponent, head loss, emission uniformity Diterima: 6 Agustus 2007; Disetujui: 12 Nopember 2007

Abstract

Total water demand at non industrial and industrial region in Cilegon is increasing. With its water production capacity of 2,000 l/s, PT Krakatau Tirta Industri (KTI) cannot fulfill the amount number of demand from the industrial and domestic sectors at Cilegon. To cover the shortage of water supply of ±600 l/s, PT KTI requires taking water from Cipasauran Watershed. The objective of this study was to analyze river discharge of Cipasauran Watershed using SWAT model. Input data such as soil characteristics, climate data, landuse, and hydrology data at the area of the watershed were gathered and put at the data input file. In SWAT simulation, 4 processes were done, i.e. watershed delineation, hydrological response unit (HRU) forming, data process and SWAT simulation, and visualization process. The result showed that the daily and monthly calibration process crossed 84% and 83% with the 95PPU area, with daily and monthly p-factor value of 0.84 and 0.83. Thus, calibrated model result was valid, though R2 and NS value were not satisfied. Using the validated SWAT model, the daily discharge in Cipasauran Watershed was about 0 - 3.309 m3/s, whereas the monthly discharge was 0.648 - 3.266 m3/s. This showed that daily and monthly PT KTI’s water demand of 0.6 m3/s were fulfilled about 98.22% and 100%. Within the future time, the SWAT model could be potentially used as an assessment for predictive scenarios. However, to gain optimum results, well-observed and precise data is highly required, especially for such calibrations and validations.

Abstract

Panen air hujan merupakan salah satu upaya yang ditujukan untuk mengurangi limpasan permukaan dan meningkatkan ketersediaan air. Panen air hujan menjadi salah satu alternative untuk memenuhi kebutuhan air masyarakat dan mengurangi penggunaa air dari PDAM ataupun air tanah. Perencanaan panen air hujan di wilayah DAS Bekasi Hulu bertujuan untuk memenuhi kebutuhan air masyarakat DAS Bekasi Hulu yang selama ini memanfaatkan air PDAM. Perencanaan panen air dihitung berdasarkan besar kebutuhan air dan jumlah volume air hujan yang dapat tertampung. Dimensi bak penampungan direncanakan adalah dengan kapasitas tampung 4 m3 dengan tinggi 160 cm tebal dinding 3 cm. Hasil perhitungan kebutuhan air penduduk DAS Bekasi hulu pada tahun 2018 adalah sebesar 73 juta m3/tahun setara dengan 110 milyar rupiah tarif PDAM. Dengan adanya perencanaan panen hujan maka diperoleh besar air hujan tertampung setiap tahunnya adalah sebesar 7.8 juta m3/tahun. Berdasarkan penelitian ini masyarakat dapat menghemat biaya air sebesar 11% dari total biaya yang dikeluarkan untuk biaya air PDAM. Pemanenan air hujan dapat diterapkan di wilayah DAS Bekasi Hulu dan sudah saatnya untuk disosalisasikan kepada masyarakat.
