Abstract

The objectives of the research were (1) To know watermelon yield and irrigation water productivity of watermelon by used drip irrigation with nylon rope emitter on various time irrigation intervals, (2) To determined the good time irrigation interval for watermelon production by using the drip irrigation with nylon rope emitter. The research was conducted at the research field with four-time irrigation intervals were 1,2,3, and 4 days of time irrigation interval. The research was arranged in Completely Randomized Block Design. The result of the research showed that the time irrigation interval was not significantly affected yield and irrigation water productivity of watermelon. The soil moisture in the root zone at 30 cm depth of 23,23—23,88% before irrigation still in range of the available soil moisture content for plants. The average of watermelon yield and irrigation water productivity of watermelon were 5,07—5,45 kg/plant and 115,15—123,79 kg/m3. The good time interval of irrigation for watermelon production by using drip irrigation with rope emitter was 4 days time interval of irrigation.

Abstract

The research was conducted at the Research Field of Lampung State Polytechnic, Bandar Lampung from August to November 2014.  The objectives of the research ware: (1) to designing of the drip irrigation with plastic rope emitter for watermelon cultivation; (2) to determining the hydrolic criteria of  the drip irrigation with plastic rope emitter for water melon cultivation; and (3 ) to  testing  the performanses of the drip irrigation with plastic rope emitter which are water storage efficiency, water distribution efficiency and water produktivity of water melon.    The result of the research showed that the drip irrigation with plastic rope emitter with 2, 3, and 4 cm length of emitter given flow rate of 7.205, 6.40, and 2.790 l/s respectively on the operation pressure of 0,15 atm. The size of 1 sub block the drip irrigation with plastic rope emitter is 15 m x 50 m for minimize pressure variation in the sub block.  The diameter and length of manifold pipe are 25 mm and 15 m, but the lateral pipe are 13 mm and 50 m. The diameter of main pipe depend on amount of the sub block   irrigated on once time irrigation. Total dynamic head for two sub blocks  irrigated is 3,44 m head and  pump capacity minimal 1,02 l/s.  The water storage efficiency, water distribution efficieny of the drip irrigation with plastic rope emitter were 100% and 87,73%.  The water melon production on the the drip irrigation with plastic rope emitter was 5,83 kg/plant was not significant different compared to furrow irrigation method was 5,64 kg/plant.  But irrigation water productivity of watermelon was significant different between of them. Water irrigation productivity of water melon by the drip irrigation with plastic rope emitter of 133 kg/plant was higher than the furrow irrigation method of 59 kg/plant.  Amount of iririgation water application on water melon cultivation by the the drip irrigation with plastic rope emitter was only 44 l/plant, but the furrow irrigation method was higher of 96 l/plant.  There for the amount of water  irrigation can be conserved on water melon cultivation by the drip irrigation with plastic rope emitter was 54%  compared to the furrow irrigation method. Keywords: drip irrigatoin, furrow irrigation, pressure operation emitter, flow rate, water melon, production, water storage efficieny, water distribution effiency, and irrigation water productivity.

Abstract

The research purposed to design and application of coconut fiber emitter of sub-surface drip irrigation for low land cabbage plant, to determine thickness of coconut fiber emitter that good  application for cabbage plant, to measure sub surface-drip  irrigation performance that are emitter discharge, wetted area diameter, water use, production and  water productivity. This research conducted at State Polytechnic of Lampung from June to November 2013. The results showed that coconut fiber emitter of sub-surface drip irrigation can be applied to  cabbage plant. Thickness of coconut fiber emitter that good application for cabbage plant was 15 mm with 10 mm fasteners diameter. Water use of cabbage plant with application of coconut fiber emitter of sub-surface drip irrigation was 0.081 m3 per plant, 38% more efficient than kettle (gembor) irrigation (0.131 m3/plant). Water productivity with coconut fiber emitter of sub-surface drip irrigation was 3.58 kg/m3, 67% more higher than kettle irrigation  (2.15 kg/m3). Keywords: design, application, coconut, emitter, drip,  irrigation, cabbage.

Abstract

The research was conducted at the PT. Momenta Agrikultura Lembang West Bandung on February to April 2015. The objectives of the research were to determine amount of water used, production, and water productivity on several varieties of salad (Lactuca sativa L.) with irrigation system nutrient film technique (NFT).  The result of the research showed that the variety of salad affected amount of water used, production and water productivity of salad with irrigation system nutrient film technique (NFT).  The amount of water used of several salad  varieties were 23.52 l/plant of cyurly salad, 25.02 l/plant of red salad, 12.71 l/plant of romain salad, and 15.09 l/plant of batavia salad for one circle of  planting 45 days.  Production of batavia salad were 170.2 g/plant not significantly different compared to romain salad of 166.0 g/plant but higher compared to curly salad of 142.6 g/plant and red salad of 94.2 g/plant. Water productivity of romain salad were 13.60 kg/m3 not significantly different compared to batavia salad of  11.91  kg/m3 but higher compared to curly salad of 6.18 kg/m3 and red salad of 3.77 kg/m3.   Keywords: salad varieties (curly salad, red salad, romain salad, and batavia salad), irrigation system nutrient film technique (NFT), water used,  production, and  water productivity

The research was conducted at the PT. Momenta Agrikultura Lembang West Bandung on February to April 2014. The objectives of the research were to determine amount of water used, production, and water productivity of salad (Lactuca sativa L.) with irrigation system nutrient film technique (NFT) with different lenght size of water chamfer. The result of the research showed that the size of length of water chamfer affected production and water productivity of salad.  The amount of water used of salad on long size of water chamfer of 24 m with NFT was 23.52 l/plant nearly same with short size of water chamfer of 6 m was 24.24 l/plant. Salad  production dan water productivity average by  the using short size of gabel was higher compared to using long size of gabel.  Salad production and water productivyti with using short size of water chamfer was average 217 g/plant and 8.95 kg/m3 water respectively but with using long size of water chamfer only 161g/plant and 6.85 kg/m3 nutrient.      Keywords: length size of water chamfer, nutrient film technique (NFT), production, water productivyti and  salad (Lactuca sativa L.)
