Abstract

The aim of this research was to observed the abundance of mycorrhiza spore and mycorrhiza colonization on G. versteegii’s root at agarwood plantation on Langko, Kekait and Pejaring. Rhizosphere samples were taken from 0 cm – 20 cm of depth. Spore extraction was carried by combination of filtration and centrifugation methods. G. versteegii roots were soaked with 10% KOH continued by 2% HCl then were rinsed by distilled water. Lactoglycerol trypan blue 0,05% were used as dye on root colonization observation. Mycorrhiza spore population and root colonization data were analyzed by ANOVA, HSD and Error Standard. Rhizosphere of Pejaring has the highest number of mycorrhiza spore but not significantly different from Rhizosphere of Kekait. Langko rhizosphere has the smallest number of mycorrhiza spore population. On the other hand, this place has the highest mycorrhiza colonization percentage among the others. It could be concluded that Mycorrhiza spore population has negative correlation with mycorrhiza root’s colonization which shows unique symbiotic between mycorrhiza and G. versteegii.

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

Agarwood (Gyrinops versteegii) and sugar palm (Arenga pinata) are essential non-timber forest products from Lombok Island, Indonesia. This research aims to conduct a 9-point hedonic scale on palm sugar candy made from a formulation of agarwood leaves infusion and Arenga sap water with different proportions. Four formulations are used as a treatment in this research, including F1 (agarwood infusion: sap water=1:2), F2 (agarwood infusion: sap water=1:3), F3 (agarwood infusion: sap water=1:4), and F4 (agarwood infusion: sap water=1:5). The 9-point hedonic scale is used in this research range from 9 (Like extremely) to 1 (Dislike extremely). Four statistical approaches were used, including Kruskall-Walllis, Freidman, ANOVA-CRD, and ANOVA-RCBD. Duncan Multiple Range Test and spider chart analysis were also used as analytical tools. Respondents were evaluated in 4 parameters: appearance, aroma, taste, and texture. The result shows that treatment significantly affects numerical hedonic scores given by the respondents in all statistical approaches. F3 has the highest numerical hedonic score in aroma and taste parameters, while F4 has the highest appearance and texture parameters. However, based on the overall evaluation, F4 is the best formulation. It could be concluded that a mixture of agarwood leaves infusion and Arenga sap water with a proportion 1 of 5 was the best formulation to produce palm sugar candy with the highest sensory evaluation score based on a 9-point hedonic scale.
