Abstract

Patchouli oil is found in all vegetative part of Pogostemon cablin. Therefore, a high biomass is important to increase production of patchouli oil. Biomass production is on of plant growth indicator. Plant growth is a effected by genetic and environmental factor. Light intensity will effect to chlorophyl syntesis, photosynthetic rate, transpiration and hormonal balance. The aim of this research is to study effect of light intensity on biomass production of Pogostemon cablin. Design of research is CRD (Complete Randomized Design), with one factor which is light intensity. There were difference of light intensity that use astreatments. These are : 96 LUX, 340 LUX and 780 LUX. Each treatment was replicated five times. Result indicated that, light intensity affect biomass production of Pogostemon cablin. At light intensity of 96 LUX, biomass productions is the most optimum. An increase of light intensity, biomass production ofPogostemon cablin is reduction.

Abstract

One ofthe way able to be conducted to improve productivity of soy is with treatment of organic fertilizer at different treatment time and dose. This research aim to to know influenceof liquid organic fertilization to soy crop productivity, knowing fertilization time and dose giving best result and also know interaction between fertilization time and dose. Researchconducted with Complete Random Device with factorial pattern . First factor of fertilization dose that is : D0 ( without treatment of manure), D1 ( 0,7 fertilizer ml / 1 water litre), D2 ( 1,4 fertilizer ml / 1 water litre) and D3 ( 2,1 fertilizer ml / 1 water litre). Second factor is time fertilization of T1 ( morning), T2 ( daytime) of T3 ( afternoon). Parameter perceived by hat isamounts of pod wet heavy of pod wet heavy of seed and dry heavy seed. Data to be analysed with ANOVA level of signification 95%, continued by test of Duncan level of signification 95%. Research result indicate that fertilization with liquid organic fertilizer complete can improve soy crop productivity, but difference of passed to dose is crop give result differ do not reality. Fertilization time at afternoon and morning cause compared to higher soy crop productivity in the day time. Fertilization in the afternoon differ reality to fertilization ofdaytime. Between fertilization dose and time there are interaction to high improvement of dry weight and crop of]soy seed.

Abstract

Land where as place growth plant must have nutrient content for support plant production. Available nutrient on soil must influence on organic substrate, because organic substrat can repairing of soil plant. Organic content in soil was decrease for a long time, it cant solution with given fertilizer. This research used organic fertilizer as cascing fertilizer with application on corn ( Zea mays L Saccarata ) plant. Main research is understand the influence of fertilizer of kascing with different dosage on production of sweet corn and understanding optimally dosage on maximally production of sweet corn. This research used RAL single factor, 4 treatment is dosage 0 gr/plant ( DO ), 125 gr/plant ( D1 ), 240 gr/plant ( D2 ), and 375 gr/plant ( D3 ). Data analysis with anova and continued by Duncan’s Multiple Range Test ( DMRT ) on level of signification 5%. Result this research indicatet that production sweet corn by treatment D1, D2, and D3 more lower compare with D0. This fact because the use fertilizer have highly ratio C/N, that hight nutrition that used by plant can’t on ready form.

Abstract

The aim of this research to know influence the salinity to growth of ginger emprit (Zingiber officinale var. Rubrum) and know NaCl concentration can maintain ginger emprit growth. Research use Complete Random Device (RAL) single Pattern. The treatment of NaCl concentration ( PO = 0 % o, P1 = 3 % o, P2 = 6%o, P3 = 9 % o, P4 = 12 % o). Colected data using analysis of variance followed by Duncan’s Multiple Range Test at 5% significance level. The results showed that treatment of different salinity give different influence to growth of ginger emprit. Treatment of concentration salinity 3%o can maintain growth of ginger emprit posed at by wet weight, dry weight and amount of bud . Excelsior salinity cause reduced of growth of ginger emprit.

Abstract

The aims of this experiment was to know corelation of distance from Sikidang Dieng with the size cover cell of stomata and distribution of leaf stomata potato. Randimized Complete Design with 9 replicates were used to experiment. The treatment was distance 100 m from cauldron, 300 m, 500 m and 700 m. Parameter was size of cover cell and sum of stomata. The result of this experiment indicated that the more far from cauldron that size of cover cell the more long, while sum of stomata the more little.

Abstract

The Aims of the research to determine the effect of soaking time and concentration of H2SO4 on the germination of seeds jati (Tectona grandis Linn. f). The research using a Completely Randomized Design (CRD) with factorial pattern   3 x 4. Factor I is a long time soaking (W1: 20 minutes, W2: 30 minutes and W3: 40 minutes), factor II is the concentration of H2SO4 (K0: 0%, K1: 70%, K2: 80% and    K3: 90%). Each treatment with three replications. The data obtained were analyzed by ANAVA at 95% significance level, followed by Duncan´s test at the 95% test level. Parameters observed were: the percentage of germination (%),hipokotil seedling length (cm), radicels seedling length (cm) and seedling dry weight (gr). The results showed there were interactions between treatment long time soaking and H2SO4 concentration on the percentage of seed germination of jati. Interaction treatment 70% H2SO4 concentration on the length of soaking of 30 and 40 minutes showed the highest percentage germination. Seeds that capable to germinate under thus treatment the seedling growth is not affected by treatment.

Abstract

The aims of this study to determine the effect of combined treatment CaCl 2 concentration and storage time on ascorbic acid concentrations and decrease of tomatoes fruit wight as well as knowing the CaCl2 concentration effect on the long shelf life. The research using CRD factorial pattern (4 x 3). Factor I is the concentration of CaCl2 (K0: 0 M, K1: 0.05 M, K2: 0.1 M and K3: 0.15 M), factor II is a long storage       (L1: 4 days, L2: 8 days and L3: 12 days) . The data obtained were analyzed by ANAVA at 95% significance level, followed by Duncan´s test at the 95% test level. The parameter is observed levels of ascorbic acid (milligram/100gram) with iodine titration method, decrease of tomatoes fruit weight and long shelf life. The results showed the interaction between the concentration of CaCl 2 and storage time treatment on levels of ascorbic acid. CaCl2 0,1 M with 4-day old store treatment shows the amount of ascorbic acid is highest. CaCl2 treatment also affects to minimize decrease of the weight tomatoes fruit and prolong shelf life of tomatoes 5 to 8 days compared to controls.

Abstract

Jatropha is an alternative resource of sustainable energi. Therefore, to support the use of sustainable energi,an increase production of Jatropha seed is important. As Jatropha seeds (fruits) only growth at terminal andaxial bud, therefore the presence of lateral bud is necessary to increase production of Jatropha seed.Formation of lateral bud is affected by the balance between auxin and sitokinin. Defoliation will control thebalance of these two hormone. In this study, defoliation is conducted on seedling at the age of 4 month.Each treatment was replicated    7 times. Variabel were observed and ended after 6 month. Result indicatecthat either defoliation will stimulated the formation and growth of lateral bud.

Abstract

The crop of rosella (Hibiscus sabdariffa var.Sabdariffa) known as medicienal crop and fiber producting crop. Last research was known as pulp. Growth of stem fiber are influenced by environmental factors. The aim of this research is to know the development of stem fiber is treated with different shading and volumes of water sprinkler. Factorial completely randomized design (RCD) was used in this research. The first factor was three levels of shading (I0: 0%, I1: 55%, I2:75%) while the second factor was three levels volumes of watering sprinkler (P1: 240 mL, P2: 480 mL, P3: 720 mL). The observed variable was total, diameter and long of rosella stem fiber cell. Collected data were analysed using Analysis of Variance (ANOVA) followed by Duncan’s Multiply Range Test (DMRT). The result of this research indicate that there are influence interaction shading and volum water sprinkler to rosella stem fiber development. Shading treatment at all volums of water sprinkler have an effect on to improve the length and diameter cell fiber, without shading treatment with volum of water sprinkler at soil field capacity of improve the amount of fiber cell.
