Abstract

Bioethanol is promising alternative fuel due to its less effect to environment. It is produced from bio-sources, such plant materials. Yeast and NPK have been reported as the ingredients in affecting bioethanol fermentation. The aim of this study was to examined the effect of yeast and NPK in bioethanol fermentation using the pericarp of “Abacaxi” pinnapple cultivar (Ananas comosus cv. “Abacaxi”). The pericarp juice of “Abacaxi” pineapple was made by blending the fresh pericarp and aquadest (1 : 1.5). The juice was then mix with dry commercial yeast (1 g, 2.5 g and 5 gr) and NPK  (1 g, 2 g, 3 g). A total of 9 treatments were used in fermentation.  Each treatment was replicated three times, brought the total sample was 27. The percentage of bioethanol for each treatment was measure using alcoholmeter for six days (24 h, 48 h, 72 h, 96 h, 120 h and 144 h). The result show that the percentage of bioethanol produced in this study varies among different treatment and fermentation time. Yeast and NPK gave significant effect in bioethanol fermentation, with the combination of 5 g yeast and 3 g NPK gave the highest percentage of bioethanol in 144 h of fermentation. Based on the result of this study, the pericarp of “Abacaxi” pineapple is potential bio-source for bioethanol fermentation.

Abstract

Obat Pahit is a potion that has been long commonly consumed by Lingga Malay society for generations as stamina keeper. The most dominant plants found in the packaging of the Obat Pahit were namely Bauhunia semibifida, Cnestis palala and Penawa Root (3 species). This research aimed to investigate and determine activity of antioxidant contents in Obat Pahit from five Traditional Medicine Practitioners (TMPs) in the district of Lingga. The tested samples were mashed then being soaked into 2 types of solvent: distilled water and methanol, containing HCl 1%. DPPH method was also used in this research. Quantitatively antioxidant activity test of Obat Pahit from the five TMPs by using methanol solvent had extremely highest activity compared to the distilled water solvent. The test, using TLC plate by spraying the extract from three dominant plants with 0.1 mM of DPPH solution, produced a pale-yellow spots at a wavelength of 366 nm. On the other hand, the test using HPLC at wavelengths of 230 nm and 280 nm showed the presence of two dominant secondary metabolites contents: flavonoid and phenolic. IC50 (ppm) of Bauhinia semibifida (6.6247), Penawa Root (5.0124) and Cnestis palala (5.9968) were much lower than IC50 of mangosteen’s rind (41.7675), vitamin C (6.6612) and Stimuno drug (8.333). This antioxidant analysis has not been reported previously. This proof contributed greatly to uncovering potentially native natural resources as an indigenous Indonesian drug which is expected to decrease dependence on imported drugs especially imunomodulator, antihypertensive, antidiabet etc. This research would be beneficial and excellent manifestation for the development of natural antioxidant-based medicines from traditional knowledge of Indonesia’s local ethnicities.

Abstract

Obat pahit has been generally known and believed by Lingga Malay society as anti-aging agent. However, the study of Obat pahit is not scientifically proven. This research was aimed to prove immunomodulatory ability of Obat pahit potion from Lingga, Riau Archipelago. This study used white rats as an animal modelling, and Staphylococcus aureus as bacteria tester. The rats had been treated with aqueous Obat pahit extract from three TMPs on dose scales of 0.09, 0.18 and 0.27 mL/200g of body weight through oral administration for 7 days. Furthermore, on the 8th days, the experiment animals were injected by the preparation of bacteria tester through intraperitoneal administration in the amount of 0.5 mL/200 gram of body weigth and subsequently incubated for 1 hour after the injection. There were 2 observed parameters on this study, i.e efectivity and capacity of phagocytosis by leukocytes. The observation of leukocytes-phagocytocis activity was carried out by making a smear preparat samples of peritoneum fluid from rats. After the observation under microscope on a magnification of 100 times. The result was obtained the Obat pahit from Kalan PMT swere more effective on dose 2, while from SP4 and Linau TMPs were much more effective on dose 1. It is therefore, using these data of the results, the advanced doses scale of this Obat pahit would not be necessary. Obat pahit potion from Malay Lingga Malay Ethnic could become raw materials of immunomodulatory herbal medicine based on traditional knowledge. It also potentially as a standardized herbal.

Abstract

Depression is a psychological disorder caused by an imbalance of neurotransmitters that can be managed with antidepressants. One of the local plants with the potential as an antidepressant is areca nut. However, its’ antidepressant effects in nonpolar solvents have not been studied recently. Equipping the extract to animals sub-chronically could mimic the clinical antidepressant treatment. Thus, the current investigation studied the antidepressant action of the hexane extract of old areca nut by utilizing acute and sub-chronic FST. This research started with extracted areca nut using n-hexane and continued with phytochemical tests. During FST, the animals were treated with n-hexane extract (50 and 100 mg/kg), fluoxetine (20 mg/kg), and saline (0.1 mL/20 g). The phytochemical test of the extract showed positive results from the content of secondary metabolites, namely saponins and steroids. n-Hexane extract at a dose of 50 mg/kg gave the best action in decreasing the immobility period. After sub-chronic medication, the secondary metabolites of the extract did not induce any toxic effects. This study’s findings imply that depression may be treated with conventional medicine, such as old areca nut extract.
