Abstract

This study aims to determine the abundance of orchid species, diversity, evenness and dominance of orchid species in the Kofiau Nature Reserve, Raja Ampat Regency. This forest area is a habitat for various endemic flora and fauna, including orchids. Orchid is one of the seed plants of the Orchidaceae family which is in great demand because of its attractive flower shape and color so that it can be used as raw material for the cut flower industry, potted plants or garden decorations. The procedure used in this study was field observation/exploration technique, the determination of the observation sample was carried out by considering the area objectively overgrown with orchids. charts, graphs and photos). Based on the results of exploration and identification of orchid species in the Kofiau Nature Reserve, there are 3 types of epiphytic orchids and 1 type of terrestrial/soil orchid, so the total number is 4 types of orchids, consisting of 1 genus of soil orchid (Spathoglotis) and 3 genera of epiphytic orchids, namely Dendrobium. 2 species and Grammathophyllum 1 species. With the highest number of individuals, Grammatophylum scriptum 128 (50.00%), then Spathoglotis plicata with the highest number of individuals, 107 (41.797%), this is the highest number of orchids found in mangrove forests, then Dendrobium allofolium with 15 individuals. (5.859%), and D. crumenatum with 6 individuals (2.344%) with a total of 256 orchid individuals found in mangrove forests. The orchid species diversity index value is 0.3771 and the dominance index is 0.4287 and the evenness index value is 0.0943. Where the index value of diversity and species dominance on orchids in the Nature Reserve forest is in the low category while the evenness index value is in the medium category.

Abstract

Aquilaria malaccensis Lam. is a gaharu-producing plant with excellent quality and high social, cultural, and economic values. Gaharu is one of the non-timber forest products with many uses, namely as a raw material for medicines, cosmetics, perfumes, incense, and preservative accessories. Gaharu is quite rare, although its cultivation can be done generatively or vegetatively. In connection with cultivation activities, quality agarwood seeds are needed. One way to do this is by giving Growth Regulatory Substances (ZPT). This study aims to determine the effect of different concentrations of shallot extract on the growth of gaharu (Aquilaria malaccensis Lam) stem cuttings. This study was arranged in a completely randomized design (CRD) consisting of 5 treatments and 3 replications, and each treatment used 5 stem cuttings. The treatment consisted of ZPT from shallots which consisted of 5 concentrations, namely: without ZPT, concentrations of 10%, 20%, 30%, and 40%. The data obtained were analyzed by analysis of variance (ANOVA), and a 5% BNT test was performed. The concentration of shallot extract significantly affected the growth of stem cuttings of Aquilaria malaccensis Lam, best at a concentration of 40%.

Abstract

The effects of greenhouse gases on daily life can cause damage to the balance of ecosystems and threaten the survival of living things. One of them is crop failure; food commodities and export products are reduced, causing food shortages and lowering the economic level of the community. The initial objectives of this study were to find or filter methanotrophic, phosphate-solubilizing, and Nitrobacter bacteria on Sorong's agricultural land. The second aim was to determine methanotrophic bacteria's potential, which can also nitrate and solubilize phosphate. The findings of the screening for methanotrophic bacteria, phosphate-solubilizing bacteria, and Nitrobacter bacteria are described in this descriptive study. In addition, isolates of methanotrophic bacteria were confirmed for their ability to decompose phosphate and fix nitrogen. The results of this study were that of the ten samples observed, five samples were detected by methanotrophic bacteria, namely MFa, MFb, MFc, MFd, and MFe samples. Furthermore, phosphate-solubilizing bacteria and Nitrobacter bacteria were found in ten isolated samples. The second conclusion, from five isolates of methanotrophic bacteria, has the potential to decompose or utilize phosphate as an energy source. Meanwhile, of the five isolates, only three isolates could utilize nitrogen as an energy source, namely isolates with MFa code, MFd isolates, and MFe isolates.
