Abstract

Avicennia marina is a species of mangrove tree occurs in the intertidal zones of estuarine areas in Asia, including Indonesia. Mangrove within the genus member of Avicennia have long dominated many coastal areas along Semarang and Demak coasts. The aim of this research was to analyze the effect pattern of several environment parameters to Avicennia seedling growth rate. Observation was held by setting 8 stations with 3 transects, each including mangrove survey and environment parameter measurements. Mangrove survey including seedling and sapling stage occupying 1 x 1 m and 5 x 5 m transect plot respectively. While environmental factor measurements including on site measurement for temperature, salinity, pH and DO and laboratory analysis for organic matter, nutrient (N,P,K) and sediment structure. The results showed there were 2 effect pattern for environmental parameters observed including polynomial quadratic and logarithmic patterns. Parameters which had polynomial quadratic pattern including salinity, DO, P, sand and silt, while parameters which had logarithmic pattern were temperature, pH, organic matter and N.

Abstract

Alfalfa (Medicago sativa L.) was one of the example plant that the chlorophyll has been used for medicine,but there were obstacles in cultivation alfalfa (M. sativa L.), becouse the seed must have been imported. Besides that,in Indonesia Alfalfa’s seed was sterile. Legume used in this research will use as chlorophyll alternative source besidealfalfa (M. sativa L.). Legume that have been examined were planted in three location with different altitude that wasSemarang (200 m above sea level), Ungaran (316 m above sea level) and Bandungan (843 m above sea level).Alfalfa (M. sativa L.) is subtropical plant meanwhile legume used to be cultivated in Indonesia is tropical plant.That’s why in this research examined legume were planted in different altitude. Purposes of this research were toknow the growth of legume, knowing if there were interaction among five legumes and planting location withdifferent altitude.. Legumes that were used winged bean (Psophocarpus tetragonolobus (L.) DC.), cowpea (Vignaunguiculata (L.), alfalfa (M. sativa L.), long bean (Vigna sesquipedalis) and common bean (Phaseolus vulgaris L.).The experimental design is completely randomize design with four replication. The data were analyzed by ANOVAtest and continued with Duncan multiple range test with 95% confidence intervals.The results showed that (P.tetragonolobus (L.) DC.) which was planted in Ungaran has the optimum growth of legume.

Abstract

Binahong (Basella rubra L.) is a plant medicine consisting secondary metabolites which have virtue asmedicines for several diseases that could also be used as coloring agent. The medicine compounds in secondarymetabolites could be extracted from callus. Sucrose is one of the components that build MS (Murashige & Skoog)medium. Sucrose is important in in vitro culture, it functions as carbon and energy source for explant to grow. Thepurposes of this research are to study the effect of sucrose in MS medium towards B. rubra L callus formation andgrowth; to find the optimum sucrose concentration for callus B. rubra L formation; and also to find the fastestinitiation time to produce callus crumb. This research uses Complete Random Design (CRD) single factor method,i.e., sucrose concentration of 0 g/l, 10g/l, 20 g/l, 30 g/l, 40 g/l with five repetitions. The data is analysed withAnalysis of Varian (Anova) and if a real difference is found the analysis is continued with Duncan Multiple RangeTest (DMRT) with significancy level of 95%. The results show that various sucrose concentrations in MS mediuminfluences callus B. rubra L induction. The highest sucrose concentration, i.e. 40 g/l, which was added into MSmedium, could induce the maximum callus wet-weight of 1,69 g and the fastest callus initiation time of 4,8 day.

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

The aim of this experiment was to study the effects of effective microorganism 4 (EM4) stimulatory on compost quality and to test of the compost with different dosage on growth and production of corn in dry land. Randomized Complete Block Design with 4 treatment and 3 replicates was use in the experiment. The treatment of compost dosage were : 0 ton/ha, 15 ton/ha, 30 ton/ha, 45 ton/ha. The parameter observedfor compost quality were : C/N ratio, . mineral content N,P,K,Ca, Mg . Heigh and dry weigh of plant, amount of fruit and seed, dry weigh of seed were observed for growth and production of plant. The results of the experiment proved that decompose of organic matter with EM4 stimulatory increase mineral content in compost. The compost treatment on dry land increase growth and production of corn. The higher dosage until 30 ton/ha of the compost the higher of growth and production of corn. The best result of the amount of seed was found from 45 ton/ha compost treatment.

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 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.
