Abstract

Bakasang laor is one of the traditional fermented fishery products in Maluku, Indonesia. There are two types of  bakasang laor, i.e. with and without vinegar. The microbiological research of bakasang processed use laor as raw material  has never been done before. The research aimed to analyze the microbiological quality and proximate composition of two types of bakasang laor.  The proximate composition can determine the nutritional value of  this product for consumption by the community. The sample of bakasang laor was taken from traditional producer in Latuhalat village, Ambon. The total number of halotolerant and coliform bacteria  in bakasang laor without vinegar were 1.7x106 CFU/g and 4.1x106 CFU/g, respectively, while the total of lactic acid bacteria in bakasang laor with vinegar was 6.0x106 CFU/g.  The carbohydrate, protein, fat and ash contents of bakasang laor with vinegar was higher than bakasang laor without vinegar. The carbohydrate, protein and fat contents of bakasang laor with vinegar were 19.64 %, 16.23 %, and 2.42 %, respectively. Generally, microbiological quality and proximate composition  of  bakasang laor with vinegar was better than bakasang laor without  vinegar. The bacteria that play a role in fermentation can be used as a starter in the fermentation of various food products.  The results of this research to improve the quality of this fermentation product in the future.

Abstract

Preventative management, such as framework-based assessment, considered as the best option for invasive species management. Alternatively, risk assessment can be conducted based on traits of occurred invasive species to build prediction system for invasive risk assessment. This study aimed to test whether trait-based assessment system can differentiate the escaped from non-escaped exotic collections of botanic gardens and to compare the reliability of trait-based versus framework-based risk assessment on differentiating these escaped from non-escaped exotics. In this study, Bayesian logistic regression analysis was conducted to assess the reliability of framework-based and trait-based risk assessment systems. For trait-based system, clear effect of leaf trait, height, and dispersal method to escape probability was detected. For framework-based system, clear effect of Tropical Weed Risk Assessment Protocol on escape probability was detected. Leaf trait, dispersal method and height are reliable predictors for escaped probability of botanic gardens exotic collection. The fact that the reliability of trait-based assessment systems is better than the commonly used framework-based system is the main novel finding in this study. This finding implies that trait-based is better than framework-based for invasive species risk assessment approach in Indonesian botanic gardens. Trait-based assessment also a relevant tool to support management with limited resources to conduct adequate early risk assessment.

Abstract

Aquaculture can be improved by a diversified approach in the form of domestication research  of a wild fish. The research has been done by cultivating Javaen Barb/Brek  (Puntius orphoides) from Serayu river, Banyumas at a natural pond and laboratory scale. Brek fish is relative slow in growth and development of gonad. This research is aimed to determine: (1) the rate of general growth of Brek in the provision of some kinds of additional food; (2) Relative Growth Rate (RGR); (3) Specific Growth Rate (SGR) and Feed Conversion (FC). The research used experimental methods. The method was a completely randomized design (CRD) of 4 treatments and 3 replicationsof: A = 100% pellet; B = 70% soybean sprout and 30% pellet; C = 70% Ipomoea aquatica leaf and 30% pellet; D = 35% soybean sprouts, 35% I. aquatica leaf and 30% pellet. Quantitative data were analysed by analysis of variance (ANOVA) of the fishes growth.The results show influence of feed types to the Relative Growth Rate (RGR) of Javaean Barb. The best RGR with the value of 72.40 was given by feed types in the D combination. Meanwhile, Specific Growth Rate (SGR) and Feed Conversion (FC) were not affected  by the feed types. The study were expected to provide suggestions for efficient feeding techniques in attempts at domestication of wild fish.How to CiteSusatyo, P., Sugiharto, S., Hana, H., Chasanah, T. (2016).

Abstract

Hornstedtia conica Ridl., Microsorum pustulatum Copel and Rourea fulgens Planch were medicinal plant used by  people of Dayak Tribes in Central Kalimantan for anti-tumor medicines. Although these plants has been widely used in traditional medicine, however, research and scientific evidence about their potential as anti-tumor are still very limited.  The research aims were to determine the qualitative content of phytochemical compounds and to study anti-tumor potential of these medicinal plants. This study used female Swiss Webster albino as a test animal.  Induction of tumor cell in mice used 7,12-Dimethylbenz [a] anthracene (DMBA), was done 10 times for 5 weeks.  Experiments were carried out used hexane extract from medicinal plants, every day for 7 weeks. The data obtained were analyzed descriptively. The results as follows: extracts of Hornstedtia conica Ridl., and Microsorum pustulatum Copel. contained alkaloids, while extract of Rourea fulgens Planch. contained flavonoids and saponins. All of these plant extracts were able to reduce the size and number of mice tumors. Hexane extract of H. conica was able to reduce the tumor size faster than another plants extracts. Mortality rate of mice in hexane extracts of H. conica and R. fulgens were zero- and in hexane extract of M. pustulatum it was 30%, meanwhile almost all mice in control group were died in days 15 of treatment. Based on this study, it can be concluded that hexane extract of H. conica and R. fulgens are potential as anti-tumor medicinal plants. These findings scientifically proved the potential of medicinal plant extracts as anti-tumor compounds.  H. conica is the most potential one for further development as alternative drug for inhibited of tumor growth.

Abstract

Seed maturity and its storage are one of problems on propagation and developing of medicinal plants such as sambiloto (Andrographis paniculata (Burm.f.) ex Nees). The research aimed to determine effects of seed maturity and storage duration on seed germination of sambiloto was conducted in a green house of Purwodadi Botanical Garden from November 2014 to November 2015. The experiment was done by completely randomised design with two treatments namely seed maturity and storage duration. The seed was classified into immature seed (0.061 g/100 seeds), semimature seed (0.113 g/100 seeds) and mature seed (0.166 g/100 seeds). The seed’s storage duration was classified into seed was not stored, seed was stored for six months and seed was stored for twelve months. Each treatment combination was replicated five times. The results showed that there were significant interactions between the treatments on percentage and rate of seed germination. The highest percentage of seed germination was the treatment of mature seed and stored twelve months (98.50%). On the contrast, the lowest seed germination percentage was the treatment of immature seed and stored twelve months (4.25 %). The fastest seed germination rate was the treatment of mature seed and stored six months (3.88 days), whereas the slowest seed germination rate was the treatment of immature seed and without stored (28.58 days). This study is expected to be applied to improve genetic and cultivation of medicinal plant as well as increasing plant growth and yield.
