Abstract

Molluscicide made from areca nut is an alternative pesticide to control snail pests. Comparing the effects of solid (powder) and extract (liquid) types of molluscicide is an effort to develop these pesticides. This study was aimed to compare the effect of using molluscicide with active ingredients of fentin acetate, areca nut powder, and extracts on golden snails in rice plants. The study used a randomized block design (RCBD), with two factors. The first factor was the type of molluscicide, namely fentin acetate, powder, and areca nut extract. Meanwhile, the second factor was the dose consisting of the recommended dose and half the recommended dose. There were 6 treatment combinations that were 5 replications. The research data consisted of mortality rates, 1, 2, 3, 7, and 14 days after applications. Data were analyzed used non-parametric analysis of variances by Kruskal-Wallis and Man Whitney Test. The results showed that there were effects of fentin acetate, areca nut powder, and extract on the mortality rate of the golden snails. The mortality rate reached 50%-75% at 3 days applications and reached 98%-100% at 7 days after applications. Furthermore, there was also showed that areca nut powder molluscicide could be an alternative to synthetics molluscicide because the areca powder nut powder tended to be more effective than other pesticides with half the recommended dose.

Abstract

Plant growth-promoting rhizobacteria are names that contribute directly or indirectly to plant growth. This group of bacteria will stimulate plant growth through the synthesis of phytohormones (bio-stimulant). Indole acetic acid (IAA) plant endogenous auxin is one of the phytohormone type that these bacteria can generate. IAA has functions for root elongation, cell division and plant growth and development differentiation. This research aims to obtain possible isolates that can generate IAA to optimize the viability of germinating red pepper seed. Bacteria have been isolated by serial dilution spread of Nutrient agar medium was incubation over a 24-hour period at 28oC (room temperature). The amount of IAA was measured by spectrophotometric analysis, selected isolate on the basis of the results, used to encourage the germination of red pepper seed. Ten out of sixteen bacterial isolates could produce IAA in the range of 7.96 ppm - 47.23 ppm. The RC 3 isolate produced the highest IAA while the RC 12 was the other way round. The isolate chosen using this experiment showed an increase in the viability of red pepper seed compare seed germination to 33%, growth spontaneity 37%, vigor index 10%, growth rates 6% and max. growth 13%. IAA isolates could therefore increase the viability of red pepper and got potential of a biofertilizer component.

Abstract

The purpose of this research was to examine the effect of phytohormone and its concentration on germination of 1-week storage G. versteegii’s seeds. Factorial Completely Randomize Design was used with two factors: type of phytohormone (J1:Atonik, J2:gibberellic acid) and phytohormone concentration (K1:200ppm, K2:400ppm). ANOVA shows that phytohormone concentration was the only factor that has a significant difference at α=0.05. Four hundred ppm was an ideal concentration that supports G. versteegii’s seed's better germination rate on atonic and gibberellic acid. However, gibberellic acid has supported a better germination rate than atonic at 400 ppm concentration. It is concluded that gibberellic acid at 400 ppm concentration is the best treatment for G. versteegii germination.

Abstract

Brownies are chocolate cakes that are very popular and liked by almost everyone. The main raw material of processing brownies is flour which until now is still imported. The addition of mocaf and moringa leaf flour can to reduce flour use and increase organoleptic of brownies. The aim of this study was to find out the effect of substitution of wheat flour, mocaf and moringa leaf flour on organoleptic brownies. The method that used in this experiment is a Complete Random Design (CRD) with one factor that was substitution of flour, mocaf and moringa leaf flour whose treatment is A0 (Flour 50% : Mocaf 50%: Moringa leave flour 0%/control), A1 (Flour 47,5% : Mocaf 47,5% : Moringa leave flour 5%), A2 (Flour 45% : Mocaf 45% : Moringa leave flour 10%), A3 (Flour 42,5% : Mocaf 42,5% : Moringa leave flour 15%), A4 (Flour 40% : Mocaf 40% : Moringa leave flour 20%), dan A5 (Flour 37,5% : Mocaf 37,5% : Moringa leave flour 25%). The data of the research were analyzed using Analysis of Varience at level 5% and tested continued using Tukey’s Honestly Significant Difference Test (Tukey’s HSD) at the same level if there was a real difference. The results showed that substitution of flour, mocaf and moringa leaf flour on brownies has a real effect on organoleptics in hedonic test on color, texture and taste as well as organoleptic scoring on color, aroma, texture and taste, but has no effect on hedonic test in aroma. For the quality of organoleptic brownies it is known that the best treatment on hedonic tests of texture and taste parameters produced by treatment A1 (Flour 47,5% : Mocaf 47,5% : Moringa leave flour 5%) with likes criteria and for scoring tests are produced by the same treatment on aroma, texture and taste parameters with their respective criteria that are typical brownies, moist and sweet taste. The best treatment on color scoring tests is produced by treatment A5 (Flour 37,5% : Mocaf 37,5% : Moringa leave flour 25%) whith criteria are brown.
