Abstract

The aim of this research was to find the effect of ratio pineapple pulps and water spinach with several arabic gum concentration on the quality of pineapple and water spinach mixture fruit leather. This research was conducted by using completely randomized design with two factors, i.e. :ratio of pineapple and water spinachpulps (%) (P) : (70:30 ; 60:40 ; 50:50 ; 40%:60% ; 30:70) and arabic gum concentration (%) (K): (1,1, 1,2 and 1,3). Parameters analyzed were moisture content, ash content, vitamin C content, crude fiber content, total soluble solid, total acid, score organoleptic values of colour, taste and texture and hedonic organoleptic values of colour, taste, flavour and texture. The results showed that theratio of pineapple and water spinach pulps had highly significant effect on moisture, ash, vitamin C, crude fiber, total soluble solid, total acid, score organoleptic values of colour, taste and texture, and hedonic organoleptic values of colour, flavor, taste and texture. Arabic gum concentration had highly significant effect on on moisture, ash, vitamin C, crude fiber, total soluble solid, total acid, and had no significant effect on organoleptic score of colour, taste and texture, and hedonic organoleptic values of texture. Interactions of the two factors had highly significant effect on total solubility solid and had no significant effect on moisture, ash, vitamin C, crude fiber, total acid, score organoleptic score of colour, taste and texture, and hedonic organoleptic values of colour, flavor, taste and texture. The ratio of pineapple and water spinach pulps of (70% : 30%) and Arabic gum concentration of (1,3%) produced the best quality of fruit leather and more acceptable. Keywords: Arabic gum, Fruit leather, Pineapple, Water Spinach

Abstract

Drip irrigation is a more economic method in distributing the water on caisim plant cultivation. This research was aimed to study the drip irrigation performance on Andosol soil with cultivation of caisim plant (Brassica juncea L.). The parameters observed were the characteristic of the soil physics, evapotranspiration, percolation, emission uniformity, use of water and the efficiency of water usage, wet weight and dry weight of caisim plant.Sanded clay textured andosol soil, evapotranspiration on the first growth phase was 0,72 mmday-1, on the middle phase was 1,92 mmday-1 and on the last phase was 0,96 mmday-1. The highest percolation was 2,65 mmday-1 on the middle growth phase on the planted soil and the lowest was 1,11 mmday-1 on the last growth on the non planted soil. The number of emission uniformity was 90,22 %. Efficiency of the highest water usage in the last growth phase on the soil without plant was 35,54 % and efficiency of the lowest in the middle growth phase on the palnted soil was 13,96 %. Efficiency of saving was 100 % on the middle growth phase and on the last. The wet  weight of caisim palnt was 129,5 g while the dry weight of caisim palnt was 7,83 g.

Abstract

Permeability of the soil is one important factor in designing drainage channels. The determination of soil permeability can be done in the field and in laboratory. The research was aimed to determine the value of permeability rate in Sei Krio Alluvial, Entisol, and Ultisol soils in PTPN II Tanjung Morawa thorugh laboratory and field tests. Results of laboratory studies showed  that the rate of permeability on Alluvial, Entisol, and Ultisol soils were, 4.39 cm/hour, and 2,14 cm/hour respectively. The value of permeability rate in the field on Alluvial, Entisol and Ultisol soils were 3.45cm/hour, 4,12 cm/hour, and 2,01 cm/hour respectively. Factor affecting the permeability differences between the three types of soil were effective depth and porosity of the soil. Differences in soil permeability in laboratory and in the field were because of the thickness of the soil. Keywords: Permeability, Effective Depth, Porosity, Drainage.

Abstract

Roughness of canal give effect to the speed of the water flow in it, which in the next, will affect to the efficiency and size of canal. Factors that affect to the canal roughness values ​​are wet surface canal constituent materials; The physical properties of the soil in canal; Irregularity of the canal; Vegetation growing in canal and scouring and deposition factor in canal. Research results indicated that scouring occured in canal which effect to the irregularities in the canal, so that solidify soil and material loading in canal surface were  needed. At the tertiary canal one manning roughness value was 0.0462 and chezy was 13.78; at the tertiary canal two manning roughness value was 0.0387 and  chezy was 15.98 and at the tertiary canal three manning roughness values was 0.0574 and chezy was 11.38.

Abstract

Seepage is one of the causes of lost of water in irrigation channel. It is difficult to measure the seepage directly on the field. Therefore there should be a model or equation to determine the channel seepage that in the first through laboratory scale. This research was done to analyze the seepage coefficient of irrigation channel on Andepts soil through laboratory scale. The water balance component which was measured were evaporation, percolation and the seepage through channel wall. The research showed that the coefficient of seepage was about 60082,56 mm/day to 65059,2 mm/day. The evaporation number value was 4,224 mm/day and channel percolation was 8925,12 mm/day. Keyword : coefficient of seepage, irrigation channel, Andepts soil, laboratory scale.
