Abstract

Noko rattan (Daemonorops robusta) and tohiti rattan (Calamus inops) are the Sulawesi local rattans that are not yet cultivated due to obstacles in its cultivation techniques, especially in seed germination. The purpose of this study was to determine the breaking of dormancy of rattan noko and tohiti seeds. The treatments used are: control, scarification, soaked in the water for 24 hours, soaked in the mono sodium glutamat solution for 24 hours, and soaked in coconut water for 24 hours. The experimental design was completely randomized design. The parameters observed were the initial moisture content of the seed, the first day of germination, germination capacity, germination rate and germination value. The results show that both rattans seeds are recalcitrant. Noko rattan is easier to germinate than Tohiti rattan and the best treatment of dormancy breaking was used immersion with coconut water. In noko rattan, broken dormancy of the 13th day with germination capacity of 91.98%, mean germination time of 32.92 days and a germination value of 0.001. Tohiti rattan was able to break dormancy in the 29th day with 88.67% of germination capacity, 58.63 days of mean germination time and 0.001 of germination value.

Abstract

Developing agroforestry systems in private forests is expected to increase productivity. This study aims to determine the appropriate agroforestry design for Falcataria moluccana-based private forests in Central Lombok Regency. Three intercrop species were tested: small taro (Colocasia esculenta), ginger (Zingiber officinale), and vanilla (Vanilla planifolia Andrews). This study was established using a completely randomized design. The three planting combinations were examined in three replications for a total of nine test plots: F. moluccana+vanilla+small taro (FmVT), F. moluccana+vanilla+ginger (FmVG), and F. moluccana+vanilla+ginger+small taro (FmVGT). Each test plot was 10 x 10 m and was located at 3 x 3 m spacing under a 3-year-old F. moluccana stand. The measured variables were crop survival rates, plant yields, and microclimatic data. The correlation between the variables was examined using the Pearson Product Moment, Duncan's advanced multiple range test (DMRT), and analysis of variance (ANOVA). The market price was used to determine the crop's economic value. The best agroforestry design was based on the economic value of crop production and the land equivalent ratio. The results indicated that the combination of F. moluccana, vanilla, ginger, and small taro, which generated an additional income of IDR 11,851,250 ha-1 a year, should be widely promoted and adopted.
