Abstract

Gynura procumbens contains tannins, saponins, steroids, triterpenoids, essential oils and flavonoids which have bioactivity as a medicine for various diseases. One effort to obtain the quality of medicinal plants uses management of soil water content. The opti-mum of soil water content will support optimal growth of a plant. Whereas in conditions of low soil water content resulted in the induc-tion of the production of secondary metabolites as a self-defense sys-tem. This study aimed to determine the effect of soil moisture content on the growth and total content of plant flavonoids G. procumbens. This study was carried out experimentally using a one-factor com-plete randomized design (CRD) consisting of 4 treatments with five replications. The treatment used is the difference in soil water content of 40%, 60%, 80% and 100% field capacity. The data obtained in the form of quantitative data will be analyzed by One Way ANOVA Test. Measurement of the content of total flavonoid compounds was car-ried out using UV-Vis spectrophotometer analysis. The results of the study indicate the influence of soil moisture level on the growth and total content of G. procumbens. Parameter growth of fresh weight, dry weight, and root G. procumbens showed an increase in 40% soil water content. The flavonoid content showed the highest total flavo-noid content 18.884 mg/g in the 40% field capacity soil water content

Abstract

Polyurethane is a class of polymers characterized by their substantial tensile strength and high melting points which enables them to be extremely durable. Despite its xenobiotic origin, polyure-thane has been found susceptible to biodegradation by microorgan-isms. The main object of this research was to investigate polyurethane degradation by the bacterium isolated from decayed teak wood (Tec-tona grandis Linn. f.). Polyurethane degrading bacteria were isolated using selective medium in the form of LB (Luria Bertani) with the ad-dition of 0.3% Impranil. Bacterial biodegradation activities shown by the changes of polyurethane structure analyzed by FT-IR spectrosco-py. The bacterial identification was carried out based on observations on the morphological characteristics of the colonies, cell morphology and sequences of 16S rRNA encoding genes. One of the potential iso-late that successfully isolated was K9, which demonstrates the disap-pearance of the 1735/cm peak of the characteristic function urethane in the FT-IR analysis. Analysis of the 16S rRNA encoding gene showed that the potential isolate having 98% similarity index to Bacillus safen-sis strain FO-36b. The activity shown by the isolate suggests that the bacteria could be a promising agent for polyurethane degradation.

Abstract

The male broodstock of Transgenic Mutiara catfish (P) (containing Clarias gariepinus Growth Hormone, CgGH) is a fish who show fast growth. Propagation of the Transgenic Mutiara catfish F1 and F2 progeny involves the crossing of broodstock P with Non Transgenic Mutiara catfish. New genetic variations (polymorphisms) can be generated from crosses broodstock P and F1 which lead to the fast growth inheritance of transgenic fish. Phylogenetic relationship analysis showed distance and genetic variation in broodstock P, F1, F2 and Sangkuriang catfish (as controls) using the RAPD-PCR method (Random Amplified Polymorphic DNA-Polymerase Chain Reaction) as the research purposes. The results showed that OPA-03 (5'-AGTCAGCCAC-3 ') primer was selective for determining phylogenetic among catfish samples. The closest genetic similarity index originates from the female broodstock of Non Transgenic Mutiara catfish (P) (93%), while the farthest originates from the male broodstock of Mutiara Transgenic catfish (P) (51%) with F1 dan F2. Closely related broodstock catfish is not recommended to be crossed.

Abstract

Lemon peel and leaf  as well as lower grade of lemon contain a considerable amount of flavonoid which can be extracted to produce a valuable product. The presence of pectin in lemon hinders the extraction of flavonoid compound. This research was conducted to examine the effect of pectin biodegradation of lemon leaf, peel, and lower grade fruit using solid-state fermentation towards the yield of pectin, crude flavonoid, and total flavonoid content. Fermentation was carried out with the help of Aspergillus niger at 30℃ for 3, 5, 7, and 9 days of cultivation time. Pectin was extracted from the fermentation broth using citric acid. Crude flavonoid was extracted using maceration and stirred about 500 rpm at 50℃ for 40 minutes. Total flavonoid content was analyzed using a spectrophotometer. The optimum cultivation time of Aspergillus niger with leaf and peel was 9 days with a pectin yield from lemon leaf was 0.43% dry weight and the pectin yield from lemon peel was 0.04% dry weight. As for the lower grade fruit, a cultivation time for 7 days showed an optimal result with a pectin yield of 0.08% dry weight. The total flavonoid content in the leaf increased up to 94.3% (1.06 mg of the quercetin equivalents per g of substrate) whereas the total flavonoid content in the peel and lower grade fruit increased up to 42% (0.12 mg of the quercetin equivalents per g of substrate) and 48% (0.021 mg of the quercetin equivalents per g of substrate), respectively. These results highlighted the potential valorization of Citrus limon L. as an alternative source for producing flavonoid in food and pharmaceutical industry.

Abstract

Red dragon fruit (Hylocereus polyrhizus Britton & Rose) is one type of cactus plant which is very potential as an ornamental plant and edible fruit. Flower is organ that play an important role in the process of breeding plants generatively. This reasearch aimed to study the anatomical structure of sepals and petals of red dragon fruit plants during flower development. The research stages included: sepals and petals sampling that held at various stages of flowering ; morphological observation (measurement length of sepals and petals); anatomical slides of sepals and petals cross section using the embedding method, anatomical observation and image capture of sepals and petals. The parameters observed were bud size, sepal length, petal length, sepal thickness, petal thickness, and tissue description composed. The results of this study indicated that buds have an increased development pattern. The increase in bud size is directly proportional to the stage of the bud. Sepal and petal are composed of epidermal tissue which form papillae, cryptophore stomata, secretory parenchyma space containing mucus, and tissues transport system is closed collateral.

Abstract

The growth of Pak Choy (Brassica rapa var. chinensis) using nutrients from catfish “Sangkuriang” (Clarias gariepinus) wastes was investigated in the household scale aquaponics systems by comparing the growth parameters value among the grow beds. The growth parameter of Pak Choy was fresh weight, leaf number, and leaf area. Meanwhile, catfish growth parameters were body weight and length, and feed conversion ratio (FCR). The experiments were arranged in a Completely Randomized Design (CRD) with 4 treatments and 3 replications. The data were analyzed using Analysis of Variance (Anova) followed by Duncan Multiple Range Test (DMRT) at 95% level of significant The result of the study showed that there were not significantly different in the growth parameter of Pak Choy among the grow beds in the vertical system. However, those in grow beds “Ä” were significantly higher than the rest of the grow beds in the horizontal aquaponics system. In general, all the growth parameter of Pak Choy in the vertical system was higher than in the horizontal one, although, it was not statistically significantly different. Nevertheless, the horizontal aquaponics system gave better results in the body weight and FCR of catfish.

Abstract

Asteraceae is one of the largest families in the Angiosperm. It comprises of 24,000‒30,000 species which are grouped into 1,600‒1,700 genera and distributed in a cosmopolitan range. Based on Backer and Bakhuizen van den Brink’s 1965 works, they identified 227 species of Asteraceae in Java. Many of them are introduced species, both cultivated or naturalized. However, the cultivated species have not been recorded. The aim of this study is to provide information about new records of cultivated Asteraceae in Java. The observations were carried out in Bandung, Bogor, and Sumedang, during January to February 2019. Nine additional species were discovered; species belonging to genera Caputia (two species), Curio (two species), Kleinia (one species), Gymnanthemum (one species), Senecio (two species), and Tarlmounia (one species). These species were grouped into two tribes: Vernonieae and Senecioneae. This study indicates that information on Asteraceae of Java need to be updated.

Abstract

 West Java Province has the largest population amongst others in Java, and therefore land conversion rate in the region is increasing. Approximately 40% of forest areas in West Java has been converted between 1990–2015. As a consequence, the number of bi­odiversity in the region is decreasing, including amphibians and rep­tiles. These groups play an important role in the food chain of an ecosystem, and are very sensitive to environmental changes. How­ever, comprehensive research on amphibian and reptile species in West Java is suboptimal. Visual Encounter Survey has performed in seven districts in West Java for one month and has recorded 26 amphibian species and 27 reptile species. These species were in­cluding Javan endemic species (for example: Fejervarya iskandari, Huia masonii, Limnonectes microdiscus, Megophrys montana, and Microhyla achatina), introduced species (Calotes versicolor), and species with a new distribution record (Leptophryne borbonica and Kalophrynus minusculus). In addition, cryptic species (Genus Lep­tophryne and Cyrtodactylus), which are interesting for further stud­ies, were observed. This study has demonstrated that the potential of a comprehensive study of amphibian and reptile species in West Java is great. Apart from this, conserving the biodiversity in the region also challenging due to the high rate in land conversion
