Abstract

Lampeni (Ardisia humilis) is a plant that can be found in Peucang Island, Ujung Kulon National Park. Lampeni are used as medicinal plants because they can produce secondary metabolites. The purpose of this study was to determine the phytochemical content and antiaggregation platelets potential of lampeni leaf. This research was conducted in September-October 2018 on Peucang Island and UNJ Biochemistry Laboratory. The phytochemical content of the lampeni leaf was in the form of alkaloids, flavonoids, terpenoids, saponins and tannins and platelet aggregation test using the Pimentel method. Lampeni leaf extract was made using simplicia and solvent which is 1:10 (w/v) with 70% ethanol solvent.  The results of the phytochemicals content test on the lampeni leaf contain alkaloids, flavonoids, terpenoids and saponins but do not contain tannins. The results of platelet aggregation test showed there was no formation of violet gel which indicated that platelet aggregation did not occur so that the lampeni leaf had the ability as an anti-aggregate platelet.

Abstract

AbstraCTIntroduction: Memory impairment is one of the symptoms of aging process which can be caused by either free radicals or oxidative stress. Antioxidants such as flavonoids are compounds that can inhibit reactive oxygen species (ROS). Bay-Leaves (Syzygium polyanthum) is one of the natural compound that contains high flavonoids. The purpose of this study was to prove that Bay-Leaves (Syzygium polyanthum) extracts prevent spatial memory impairment in male Balb/c mice (Mus musculus) with brain aging.Methods: This study was a true experimental study with randomized pretest-posttest control group design. The experimental animals were 14 mice, which were divided into two groups (7 each group). Mice that were included in this study were healthy (active and willing to eat), weighing 20-22 grams, 3-month-old With oral D-galactose (300mg/kgBW/day)induced brain aging for 28 days. The control group was treated a placebo (2 ml of aquabidest), and the treatment group was treated with oral Bay-leaves extracts at a dose of 5.25 mg/kgBW/day. Spatial memory was examined using the Morris Water Maze method using Probe Test to assess spatial memory retention and the Number of Platform Crossing Test. The examinations were done before (pretest) and after treatment (posttest) with placebo and Bay-leaves extract for 28 days.Results: The results showed that in the Probe Test, before the treatment (pretest) in the control and treatment groups there were no differences (69.94 ± 4.46% vs 69.42 ± 4.30%; p = 0.831), but after treatment during 28 days (posttest), the mean of the Probe Test between groups was significantly different (52.02 ± 7.46% vs 66.08 ± 3.72%; p = 0.001). In the Number of Platform Crossings, before the treatment (pretest) there was no difference in the Number of Platform Crossings (6.92 ± 0.640 times vs. 7.10 ± 0.748 times; p = 0.640), but after treatment for 28 days (posttest), the mean Number of Platform Crossings between groups was significantly different (4.67 ± 0.590 times vs 6.46 ± 0.809 times; p <0.001). For intergroup tests, the Probe Test in the control group decreased significantly (from 69.94 ± 4.46% to 52.02 ± 7.46%; p = 0.001), whereas in the treatment group there was no decreased (69.42 ± 4.30% to 66.08 ± 3.72%; p = 0.060). In the Number of Platform Crossings test, there was a significant decrease in the control group (6.92 ± 0.640 to 4.67 ± 0.590, p = <0.001), whereas in the treatment group there was no decreased (7.10 ± 0.748 to 6.46 ± 0.809, p = 0.070).Conclusion: Based on the results of this study, it can be concluded that Bay-Leaves (Syzygium polyanthum) extracts prevented the decrease of spatial memory in male Balb/c mice (Mus musculus) with brain aging.

Abstract

Heavy metals can generally act as EDCs. Likewise chromium hexavalent may serve as a Endocrine Disrupter, especially the fish reproductive system. This study aims to determine the effect of chromium hexavalent on estradiol content, ovarian development and liver of nilem female (Osteochilus hasselti C.V.), the researchers also want to see the dose of chromium hexavalent most influential on estradiol levels, ovarian development, and liver of nilem fish (Osteochilus hasselti C.V.) as well as the interaction between reproduction parameters with water quality of maintenance media of nilem fish (Osteochilus hasselti C.V.).This study uses the method of "quantitative experimental". The experimental design was Completely Randomized Design with treatment of chromium hexavalent dose of 0, 0.009, 0.018, 0.027 and 0.036 mg/L performed in 5 replications at 3 stages, ie 1st, 2nd, and 3th months post-spawning maintenance. At 1st month of maintenance, chromium hexavalent did not significantly affect the reproductive parameters of GSI (Gonadosomatic Index), fecundity, HSI and estradiol. The chromium hexavalent had no significant effect on GSI, fecundity and estradiol and significantly affected HSI at 2nd months of maintenance. Chromium hexavalent significantly affected GSI, fecundity, HSI and estradiol in a 3th month maintenance trial.

Abstract

The Pasirbatang rehabilitation zone is part of the Ciremai Mountain National Park (TNGC) which is on the south side has experienced degradation. Therefore, planting was carried out in this zone with local species in 2014. The purpose of this study was to determine the vegetation structure and richness of the Ficus clan in the rehabilitation zone. This research was conducted in July-September 2018 with the method of placing the sampling plot on the specified path. A total of 31 species were found at various levels of growth with the Important Value Index (IVI) at the tree level (192.12%) in the form of Pinus merkusii, pole level (66.38%) in the form of Nauclea lanceolata, sapling level (141.72%) and seedlings (148.69%) in the form of Caliandra callothyrsus. Potential of Ficus spp is spread in various growth rates, namely species of F. septica, F. ampelas, F. variegata and F. fistulosa with the highest density at seedling level (166 ind / ha), and followed by sapling levels (64 ind / ha), poles (16 ind / ha) and trees (0.67 ind / ha). This Ficus wealth is considered important for the zone rehabilitation program in the Mount Ciremai National Park

Abstract

Agarwood (Aquilaria malaccensis) is an important species with high economic value and has many benefits, which led to an overexploitation in its natural habitat.  An effort to both provides sufficient seedling for agarwood cultivation and conservation is therefore much needed. This study has been carried out with a view to determine the effect of media types and BAP concentrations in two steps cultivation system on agarwood microshoot induction. This was a two stage-experiments i.e., microshoots induction and optimizing shoot development.  The research results showed that the interaction between different media type and BAP concentrations had no significant effect on agarwood microshoot induction.  Subsequent culture on MS media without any BAP addition showed that explant derived from MS medium solidified with 2.5 gr. L-1 Phytagel produced 2.36 ± 0.48 shoots/explant and 3.69 ± 1.16 leaves/explant.  In addition, explant derived from culture on MS medium supplemented with 4 µM BAP produced 2.28 ± 0.61 shoots/explant. This is for the first time the application of two steps culture system for Agarwood (Aquilaria malaccensis) has been deployed and how the habituation phenomenon is handled.

Abstract

Reinwardtiodendron humile (Hassk.) Mabb. is one of the members of the Meliaceae tribe with the potential to be developed and consumed as fresh fruit or processed fruit. This research aims to determine the proximate composition or nutritional values contained in R. humile. Proximate analysis of R. humile included analytical determinations of water, ash, crude fat, protein, crude fibre, and carbohydrates. All tests for each of the parameters or components were carried out two times. Then, the contents determined through proximate tests were calculated using certain formulas. The results of this study indicate that the proximate composition of R. humile consisted of water, ash, fat, protein, crude fibre, and carbohydrates (74.2% - 75.28%; 1.35% - 1.54%; 0.53% - 0.72%; 2.48% - 2.73%; 0.86% - 3, 47%; and 16.7% - 20.14%). These results meant the fruit contents met the quality standards of fruit, except for the protein content. The results of the analysis of the proximate composition also show that the nutritional values of R. humile fruit did not significantly differ from the nutritional values of other fruits of the Meliaceae tribe commonly consumed by humans, such as duku, langsat, and kokosan.
