Pandanus species is widely distributed over Bukit Duabelas National Park in Jambi. Suku Anak Dalam (SAD), a local community living in Bukit Duabelas National Park area, use the natural fibers from Pandanus for many necessities, such as plaiting, building materials, and performing mytological rituals. This study aimed to examine floristic composition, distribution patterns, and association of pandanus species in Bukit Duabelas National Park. Sampling was conducted using a striped line, with a plot of 35 sample plots. Dominance of species was calculated using dominant type of important Value Index (IVI) based on the density, frequency, and dominance of sample plot enumeration. Distribution patterns was analyzed using the Morisita Index, while association patterns were measured by Contingency tables and Chi-square tests. Floristic composition was mostly found in the seedling strata consisting of 106 species. The species with highest important value index (IVI=14.53) was Palaquium gutta. There were two species of Pandanus (Benstonea kurzii and Benstonea atrocarpa) were spread in groups and three species of pandanus (Pandanus labyrinthicus, Pandanus furcatus, and Pandanus immersus) were spread evenly. The pandanus species found was associated with Benstonea kurzii was Litsea sp1. This present study suggested that the conservation of pandanus species should be conducted as a piece of rehabilitation of tropical forests in Bukit Duabelas National Park.

The shell of snail contains chitin that can be transformed into chitosan through four stages, which are deproteination, demineralization, depigmentation, and deacetylation. Chitosan can be utilized as an antibacterial agent because it has amine groups. In this research, chitosan that prepared from the snail shell will be analyzed using FT-IR spectroscopy to determine the deacetylation degree (DD). The antibacterial activity test result of Staphylococcus aureus will be carried out on chitosan with various concentrations using in-vitro Kirby Bauer method and will be analyzed using One Way ANOVA with confidence level at 95%. The variations concentration of chitosan used is 300, 400, 500, 600, and 700 ppm. The result shows that the deacetylation degree of chitosan is 63.09% and the optimum concentration of chitosan that can inhibit the Staphylococcus aureus bacteria is 500 ppm with diameter inhibition is 34.33 mm.

Microalgae is an aquatic microorganism that conducts photosynthesis. It plays a vital role as an oxygen producer in the marine ecosystem. A freshwater microalgae, Haematococcus pluvialis, has been utilized as a health supplement and industrial application which is beneficial for human. In addition to physical and chemical factors, nutrient composition is one crucial thing that contributes to the growth of microalgae. This present study aimed to determine and compare the growth rate of Haematococcus pluvialis cultivated in two culture medium, Walne’s and Guillard. The culture conditions observed were light intensity, photoperiod of light-dark hours, temperature, inoculum concentration of medium’s liquid, and cell density. This study confirmed that Walne’s media produced much higher biomass (247x104 cells/mL) than Guillard’s medium (209.6x104 cells/mL). The aspect to be further performed on H. pluvialis biomass is exploring its high-value bio compound.

The previous study stated that there are 12 species of Amphibians found in Lombok Island, Indonesia. Four of which are the endemic species of Lesser Sunda Islands, namely Oreophryne monticola, Limnonectes kadarsani, Limnonectes dammermani dan Hylarana florensis. However, the information regarding the habitat characteristic which supports animal survival is limited. This study aimed to explore the types of habitat characteristics according to amphibian diversity in the Island of Lombok. The survey study was conducted at 9 locations (3 of habitat type) from March to July 2016. The collected data includes species composition and a sum of individuals of species. Amphibian diversity was analyzed using relative abundance and the Shannon-Wiener index. This study revealed that the nonforest habitat type was appropriate for five species, while secondary and primary forest habitat type was appropriate for seven species. Diversity of species index directly proportional to a natural level of habitat (H’ Nonforest = 1.3; H’ Secondary Forest = 1.7; H’ Primary Forest = 1.8). The highest species abundance was Bufo melanostictus (23.9%), and the lowest species abundance was Oreophryne monticola (0.9%). According to the distribution and relative abundance, the species that require conservation priorities are Oreophryne monticola and Hylarana florensis.

The cell wall component of root endophytic fungi is a main source of chitosan synthesis. This research aimed to optimize chitosan synthesis from three different isolated species of root endophytic fungi in Pulau Dua Nature Reserve, Banten Indonesia. Three species of root endophytic fungi, namely, Aspergillus niger, Aureobasidium sp., Basipetospora sp., were cultured to produce chitosan. To optimize the production of fungal chitosan, cultures were treated with different conditions such as growth medium (Oat Meal broth, Potato Dextrose Broth, CMMY Broth), pH value (4, 5, 6, 7), and temperature (25, 30, 35, 40°C). Chitosan was extracted from dried mycelium after treated on NaOH 10% at 121°C for 2 min. The degree of deacetylation (DD) of chitosan was then examined and compared with the control (shrimp chitosan). The optimum fungal chitosan condition was higher in CMMY medium, pH 5, and 30°C. The DD value of three root endophytic fungi species, Aspergillus niger, Aureobasidium sp., Basipetospora sp. were 88.5, 83.3, 80.8, respectively, which was lower than DD value resulted from control. This study indicates that Aspergillus niger was a potential endophytic fungi for chitosan synthesis.
