Abstract

This study aimed to determine the effect of granule growing media on growth and yield of vegetables in ahidroponic wick system. The design of this study used Randomized Complete Block (RCB) with factorialarrangement and three replications. The first factor consisted of three levels : kale (S1), spinach (S2), andmustard (S3). The second factorwere the size of the granules with four levels : 12mm (M1), 6mm (M2), 4 mm(M3) and husk char (M4) as a control. Each plant was grown in a wicked pot. There were 12 treatmentcombinations, with three replicates. Parameters observed were physical properties of the media,evapotranspiration, number of leaves, growth, biomass, and yield. Data was analyzed using the Analysis ofVariance (ANOVA) 1%and 5%levels of significance, followed by LSDcomparision. Results showed that therewasno significant interaction betweenmedia and types of plant. However; sizes of media significantly affected theevapotranspiration, growth, biomass, and yield.Keywords:Wicked, hydroponics, granules, media, vegetables

Abstract

The aim of this research is to know the effectiveness of intermittent irrigation and water productivity analysis, analysis of optimum irrigation interval on plant material of mixed solids of digestat and soil mixture, analysis of optimum combination of digestat solid and soil for plant, and growth and yield analysis Pak Choi plant production. The research was conducted at Greenhouse Plastic Department of Agricultural Engineering Faculty of Agriculture, University of Lampung in November 2016 until December 2016. This research uses two factors of observation, namely Composition of Planting Media and Interval of Irrigation Time. This research used 4 mixed treatment of plant media composition, that is D0 (Digestat 0%: Soil 100%), D1 (Digestat 20%: Soil 80%), D2 (Digestat 40%: Soil 60%), and D3 (Digestat 60% : Soil 40%). Each mixture of media was done 3 repetitions, so that 12 pots were observed. The results showed that the combination of planting medium D1 (Digestat 20%: 80% soil) resulted in a high enough on pak choi of 122.7 grams, while for treatment result D0, D2 and D3 there was a less significant difference. The provision of irrigation water with intermittent irrigation does not significantly affect the growth and yield of Pak choi plant. Longer water delivery intervals still provide a good effect on the results of pak choi plant production due to the addition of solid digestat on the planting medium. The highest water use productivity was achieved by treatment D1 with an average of 774 g /m3. Keywords : Digestat, Intermittent Irrigation, Media Planting, and Pak Choi.

Abstract

Water is a natural material that is very important for humans, animals and plants. Apart from being used as consumption, water can also be used as an energy source, with the need for water use which is very important for humans, it needs to be supported by an increase in water supply. Water supply usually uses a pump that functions to raise water from a lower place to a higher place. However, there are still many people who still have difficulty meeting their water needs due to the weak purchasing power of the people to buy pumps, especially in rural areas. Therefore, it is necessary to design a hydraulic ram pump which is one solution to overcome this problem because it is cheap and simple to manufacture and maintain. A hydraulic ram pump is a pump that can raise water from a low place to a higher place using energy that comes from the water flow itself. To find out the performance of the hydraulic ram pump, a pump efficiency test was carried out with the treatment of different heights of water flow sources, different heights of water lifted and different exhaust valve loads. The results of efficiency testing are obtained that the higher the water flow source the greater the efficiency, the lower the water lift the greater the efficiency and the lightest load on the exhaust valve has the greatest efficiency. Keywords: water, pump, hydraulic ram pump, efficiency

Abstract

The purpose of the fertigation system is to meet the needs for irrigation and fertilizer for plants provided simultaneously through the drip irrigation system. Appropriate application of fertilizer and irrigation (both quantity and time of application) is the key to the growing process of shallot plants. The aim of the research was to test the fertigation system, analyze the performance of the fertilizer injector, and determine the uniformity of the drops in the drip fertigation system. Fertigation with a drip irrigation system design using a dripper line emitter (Streamline X, 16 mm diameter) with a spacing of 30 cm, 1-2inch PVC type manifold pipes, 4inch main pipe PE type, and 2 - 3inch PE type sub-main pipe. The water distribution method used a pump with a discharge of 13 m³/hour, a fertilizer injector with an injector (dosing proportional mix-rite), and an automatic control box system using NMC Pro. The variables observed were coefficient of uniformity (CU), fertilizer injector performance, and wetting diameter on the soil surface. The results showed that the appropriate fertilizer injector size setting for plant growth in each shallot growth phase was 0.3, 0.4, and 0.5. The irrigation efficiency and CU value were 96 % and 86 % respectively, which means that the water distribution via dripper lines has good uniformity with an average wetting diameter of 22 cm. Keywords:  Coefficient of Uniformity, Dripper Lines, Fertigation, Fertilizer Injectors, Shallots.
