Abstract

Nipah or Nypa fruticans Wurmb is a member of the Palmae tribe that lives in the Mangrove ecosystem and is known to have rich bioactive sources, one of which is antioxidants. The ability of N. fruticans as an antioxidant is also possible for endophytes associated with N. fruticans. This study aims to obtain endophytes that live in N. fruticans leaf tissue and find out their ability as antioxidant agents using synthetic free radicals 2.2 diphenil-1-pikrilhidrazil (DPPH). Samples taken at Nipah Panjang Tanjung Jabung Timur, Isolation and production were carried out at the Jambi University Faculty of Science and Technology Engineering and Biotechnology Laboratory, absorbance measurements using UV-VIS at λ 517 nm at the Jambi University CRC. The antioxidant activity of isolates was shown from the value of Inhibitor Concentration (IC50) which caused 50% loss of DPPH free radicals. From the results it was obtained that the six isolates (DN01, DN02, DN02, DN03, DN04, DN05, and DN06) value the antioxidant activity of endophytic extracts lower than vitamin C activity and still classified as weak. Even though endophytic Nypa fruticans are very weak, N. fruticans endophytic in all treatment concentrations still have the ability as antioxidants and optimization methods are needed to get good antioxidant values. Keywords: Mangrove, Nypa fruticans Wurmb, endophytes, antioxidants, DPPH

Abstract

Nypa is a mangrove plant that acts as a food source, such as nata. Research has shown that nipah plant waste, such as frond fibers and nipah fruit skin fibers, can be used as a raw material in making nata fruticans. The purpose of this study was to determine the potential of nipah fiber (Nypa fruticans Wurmb.) in nata production using soybean sprouts as a nitrogen source. The samples of nipah fiber (Nypa fruticans) used were leaves (DN), midrib (PN) and fruit skin (KB), taken in the Kuala Tungkal area, West Tanjung Jabung Regency, Jambi Province. This research method includes making the mother solution, making nata starter, and producing nata sheet by using soybean as a source of nitrogen with a concentration of 5%, 10% and 15% and ZA as a control. The results of this study indicate that the best volume and thickness of nata fruticans can be seen from the midrib substrate with a concentration of 10% soybean sprouts. The yields produced for all treatments were still lower compared to controls. Meanwhile, the water content of all treatments was better than the control. The best quality of Nata Fruticans based on thickness, yield and average moisture content was generally obtained from the substrate from the leaf midrib fibers with a concentration of 10% soybean sprouts

Abstract

One of the largest composition in peatlands is Cellulose. It can be degraded by cellulase enzymes. Sungai Buluh Peatland is one of the large and protected peatlands in Jambi Province. This land can be the main habitat for cellulolytic bacteria. Peatlands cellulolytic bacteria have great potential as biocontrol agents for plant pathogenic fungi. This study aimed to obtain cellulolytic soil bacteria from Sungai Buluh Tanjung Jabung Peat Protection Forest, in the East Tanjung Jabung, Jambi, which causes stem rot disease of oil palms. This research was carried out in several stages. Firstly, soil samples were collected from the Sungai Buluh Protected Forest, East Tanjung Jabung Jambi. Then the bacteria were selected on Carboxy Methyl Cellulose (CMC) selective media and the quantitative cellulolytic activities were measured based on clear zones that formed on CMC media. The results showed that 25 isolates of cellulolytic potential bacteria were obtained from the Sungai Buluh Peat Protected Forest area, 8 of them had cellulolytic activity range from 0.87 to 6.70

Abstract

Diabetes mellitus (DM) is a chronic metabolic disease. It was caused by lack of insulin or cells cannot use insulin so that blood glucose becomes high (hyperglycemia). And it will cause other systemic diseases of the disease (metabolic syndrome) that can increase the factor of death. Coffee is one of the consumed plants that contain antioxidants and chlorogenic acid that have a role as antihyperglycemia. In other hand Jambi as one of the coffee producing regions (arabica, robust and liberica) in Sumatra and it has a potency as a coffee producer. In addition, people's habits in consuming coffee have the opportunity to be one solution in overcoming diabetes. This study aimed to determine the effect of hyperglycemia disease. The method was experimental with 5 treatments (metformin, arabica, robust, liberica and aquades) and 3 replications. Before threatments mice were injected with streptozotosin in order to be hyperglycemia, then mice with blood glucose ≥ 116 mg / dl were measured their blood glucose, weight and made the histology of the liver. Then the datas were analyzed using ANAVA. The results showed that Jambi coffee (arabica, robust and liberica) can lower blood glucose levels hyperglycemia mice until day 16. And the treatment with liberica coffee lowers hyperglycemia with the lowest glucose levels. While the histological features of mice liver showed lower cell degeneration especially in mice by coffee treatment, especially arabica coffee.
