Abstract

The tomato (Solanum lycopersicum L.Var. Permata) is one of the horticultural crops that contain vitamin C with potential for health. During the ripening process in storage, the tomato will experiencea more rapid weight loss and decay caused by respiration and bacteria. The storage life of the tomato can be extended by adding edible film from plant extracts that contain secondary hydrocolloid and metabolite compounds. This research aimed to find out the effect of the bandotan (A. conyzoides L.) leaf extract of different concentrations on the freshness of the tomato (S. lycopersicum L.) and to find out the best concentration of the bandotan (A. conyzoides L.) leaf extract to maintain the freshness of tomato (S. lycopersicum L.). The research was carried out from February to April 2015. The experiment used in this research was a completely randomized design. The concentrations of the bandotan extract used consisted of 4 treatments i.e. 0 ppm (P1), 10 ppm (P2), 20 ppm (P3) and 30 ppm (P4). The research findings indicated that the 30 ppm treatment was better at a weight loss parameter of 8.67 and a density of bacteria at 70.5 x 103. The treatments of 10 ppm, 20 ppm and 30 ppm had the ability to maintain the content of vitamin C.

Abstract

Holothuria atra is marine creature which is potential as a source of antifungal material.This research aims to find out the antifungal activities of the extract of H. atra against the Malassezia furfur fungus that causes tinea versicolor. The extract of H. atra was obtained through a maceration method using methanol. The antifungal activities were tested using Kirby-Bauer disc paper diffusion method on the Saboraud Dextrose Agar (SDA) medium enriched with olive oil. The research used the extract with concentrations of 20%, 40%, 60%, 80%, and 100% with 2% of ketoconazole positive control and DMSO (Dimethyl Sulfoxid) negative control. The secondary metabolite test indicated content of alkaloids, triterpenoids, and saponins in the extract. The test results of antifungal activities showed that alllevels of concentration could inhibit the growth of M. furfur fungus characterized by the formation of a clear zone around the paper disc. The extract of H. atra is fungistatic with a very strong inhibition category. The concentration of 20% is the most effective in inhibiting the M. furfur fungus with a clear zone diameter of 22,16mm.

Abstract

Staphylococcus aureus is a pathogenic bacterium that causes infection to wound, and Salmonella typhi is a bacterium that causes typhoid. The dragon scales (Drymoglossum piloselloides) is one of the plants that can potentially serve as an antibacterial agent. This research aims to find out the class of compound of secondary metabolites and the antibacterial activities of methanol and ethyl acetate fractions of the dragon scales against S. aureus and S. typhi bacteria. The study was conducted for 3 months with a disc diffusion method (Kirbybauer). The concentrations of methanol and ethyl acetate fractions of the dragon scales used in this research were 0,25 g/mL, 0,3 g/mL, 0,35 g/mL, ciprofloxasin 0.005 mg/mL as a positive control and DMSO 10% as a negative control. Research findings showed that the methanol and ethyl acetate fraction contained flavonoidand terpenoid compounds. The methanol fraction of the dragon scales had antibacterial activity against S. aureus bacterium with a strong response at a concentration of 0.25 g/mL while the ethyl acetate fraction had no antibacterial activity against S. aureus and S. typhi bacteria.

Abstract

Jabon (Anthocephalus sp.) is native species of Indonesia and the cultivation of white jabon in west Kalimantan is still rare. One of the efforts to increase the production of jabon is through vegetative propagation shoot cutting. Propagation through shoot cutting often fails, in which the roots cannot grow. One of the ways of overcoming such failure is by providing exogenous growth regulator, namely, goat urine. This research aimed to find out the effect of the concentration of goat urine (Capra aegagrus) and soaking time on the growth of the shoot cuttings of white jabon. This research used a completely randomized factorial design (CRD) i.e. the factor of concentration (A) consisting of 4 levels of 0%, 6%, 8%, 10%, 12% and the factor of soaking time (B) consisting of four levels, i.e. 0 min, 5 minutes, 10 minutes and 15 minutes. The treatment was repeated three times. The research findings indicated that adding goat urine concentration of 12% and 15 minutes soaking time generated the average root number of 29 pieces, the plant height of 20.33 cm, thewet weight of 16.33 grams and the dry weight of 3.46 grams, and the average number of leaves of 9 pieces, which were obtained from the treatment of a concentration of 10% and a soaking time of 15 minutes.

Abstract

Benthos are organisms that live on bottom of the water body, either in the form of animals and plants, living on the surface or in the bottom of the water. This research animed to find out the diversity of the species of macrozoobenthos in the Rombok Banangar River. The research began from November 2013 until January 2014. The samples of macrozoobenthos were collected using the Surber net and Ekman Grab based on the differences of the substrate on the riverbed. The macrozoobenthos found in the Rombok Banangar River were comprised of two Phyla i.e. Arthropods and Mollusks. The Phyla of Arthropods found were of the Insect class which falls into the genera Hydropsyche, Polycentropus, psephenus, Dryops, Anthopotamu, Acroneuria and Triops. Phyla of Mollusks found were of the Bilvavia class which falls into the Genus of Corbicula and of the Gastropod class of the Genera of Melanoides and Melanatria. The highest abudanceof the macrozoobenthos at each station was Polycentropus (66,67 ind/L) and Potadoma (266,67 ind/L). The highest abudance of the macrozoobenthos found was the Melanatria at 622,2 ind/L. Based on the values of Diversity index (H) (0,367 – 0,602) dominace index (C) (0,132 – 0,386) and evenness index (E) (0,367 – 0,602) the Rombok Banangar River falls into the category of good condition with a high species diversity. The physical and chemical factors of the water body are able to support the life of the macrozoobenthos.

Abstract

Arabica coffee (Coffea arabica L.) is one of the commodities witha high economic value. The production of the arabica coffee plant (C. arabica L.) is influenced by seed dormancy. This research aimed to find out the effect of sulfuric acid (H2SO4) and gibberellin (GA3) in accelerating the dormancy breaking and germination of the seeds of arabica coffee (C. arabica L.). This research used a completely randomized design (CRD), which consisted of two factors. The first factor was the concentration of H2SO4consisting of 5 treatments, i.e. the concentration of 0% (A0), 5% (A1), 10% (A2), 15% (A3), and 20% (A4). The second factor was the concentration of 0 ppm GA3 0 ppm (B0), 20 ppm (B1), 40 ppm (B2), 60 ppm (B3), dan 80 ppm (B4). Each treatment was repeated 3 times, so 75 experimental units were obtained. Data were analyzed using ANOVA (Analysis of Variance) and a further test using the Duncan test. The research findings showed thatthe treatment of sulfuric acid (H2SO4) at concentration of 10% was the best concentration for accelerating the growth ofthe seed of arabica coffee (C. arabica L.) with a percentage of 57.18%. The combination of sulfuric acid (H2SO4) of 10% and gibberellin (GA3) of 40 ppm was the best concentration for the growth of germination of arabica coffee (C. arabica L.) with a percentage of 38%.

Abstract

The anthurium seedlings are not only supplied through vegetative propagation, but also through generative propagation, i.e. plant crossing that also functions to enhance the exotic values which are different from the parent anthurium. Crossing the parent anthurium not only produces new plants with a different morphology, but also affects the anatomy of the plant itself. This research aimed to find out the anatomical structure of the root, stem and leaves of A. plowmanii and A. hookeri as well as the hybrid of both plants. The research was carried out from January to September 2015. The preparations of the organ incision were made using aparaffin method. The structure of vascular bundles of the A. hookeri stem showed a significant difference compared to the other two types. In addition, the ergastic substance was found more in the hybrid plant compared to both of its parent plants.
