This study aims to document the traditional uses of plant species traded in three traditional markets in Tabanan regency. Data collection was carried out by semi-structured interview toward 64 traders of Baturiti, Marga, and Tabanan traditional markets, respectively. Data analysis was performed quantitatively by calculating the use value index, and some ecological indices, such as diversity index, margalef index, pielou index, sørensen index, cluster analysis, and principal component analysis. Qualitative analysis was also used to tabulate and presented the data into tables and figures. The study documented 52 plant species belonging to 48 genera and 30 families. Herbs are the most widely used habitus, and Zingiberaceae is the most widely used plant family. The most widely used use-category is condiments, and Cocos nucifera is a plant species with the highest use-value. The study also showed a highly plant diversity, which is traded in each market, with slightly different similarities. Cluster analysis and PCA showed that there is a little difference in plants species traded in three traditional markets. Differences in altitude may affect the diversity of plant species traded, including the buyer's preference (community).","PeriodicalId":280065,"journal":{"name":"BERITA BIOLOGI","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133052081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of ten accessions of yam bean was planted at Kendalpayak Research Station, Malang (Indonesia) from May to October 2016. Yam bean pods of each accession were harvested at three developmental stages, i.e. full-size green pods, yellow pods, and brown/black pods. The experiment was conducted using a completely randomized factorial design with three replications. The first factor was pod maturity and the second factor was yam bean accessions. Significant interactions between pod maturities with accessions were found on characters of epicotyl length, leaf length, leaf width, root dry weight, maximum growth potential, and germination rate at the 10th days of observation. The pod maturity at yellow stage gave the highest maximum growth potential and germination rate. The average germination rate of yellow pods was 8.15% per day which was, higher than those of green pods (3.83% per day) as well as black pods (3.73% per day). These yellow pods have optimal germination growth of compared to those of green as well as black pods. The practical implication of this research is the use of yellow pods as recommended seed source for yam bean cultivation.

The high production cost is related to the high price of feed. Fish growth can be triggered by an optimal feeding. A feeding strategy is needed to improve the efficiency of production cost. This study aimed to determine the profitability and the performance of the seedling thai mahseer fish with different feeding frequencies. This study was conducted in Germplasm Research Station, Cijeruk in March-April 2014. The fish used in the experiment have a standard length of 2.29 ± 0.12 cm and weight of 0.32 ± 0.07 g derived from induced breeding spawning of the broodstock natural catches which was adapted for four years in pond concrete. The fish were reared in the aquarium (dimension= 40 x 30 x 30 cm) with a water height of 20 cm and a stocking density of 50 individuals each. The experiment was designed by using three treatments and three replications for each treatment. Fish were feed using commercial feed (protein content = 28%) as much as 20% per day of the total biomass. The treatment observed was feeding frequency, namely (A) three times/day, (B) twice/day, (C) once/day. Results of the experiment for 40 days showed that the increasing values of length, weight, specific growth rate, survival rate, biomass and FCR were not significantly difference (P>0.05). The highest benefit value was obtained in the treatment of feeding with a frequency of three times/day (Rp. 332.304 ± 14.819,-).","PeriodicalId":280065,"journal":{"name":"BERITA BIOLOGI","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116460676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Information related to the diversity of Physalis spp. in Indonesia is limited. The objectives of the research was to identify the diversity of wild Physalis sp. on Mt. Kelud, East Java based on morphological characters, total protein profiles, and flavonoid compounds. The research was conducted by survey on some gradients viz. 200–400, 400–600, 600–800, 800–1,000 and >1,000 m above sea level. Identification of morphological characters was focused on root, stem, leaf, flower and fruit covering 16 characters for scoring. Identification of total protein profile was performed by SDS-PAGE method and the flavonoid compound was analyzed using UV spectrophotometric method based on the colorimetric principle. The degree of diversity of Physalis spp. was determined based on morphological similarity and total protein profiles through cluster analysis. The results showed that Physalis spp. on Kelud was found up to 1,000 m above sea level. Altitude affected to the morphological diversity, total protein profile and the flavonoid compound. Morphological features that play a role in the diversity of Physalis sp. were the direction of growing stems, leaf shape, leaf margin, leaf surface, leaf stalk color, stain color on the inner neck of thr flower, and fruiting calyx color. Expression of total protein P. minima. shows similarity to P. angulata L. Physalis sp. in the low gradient have a higher flavonoid compound as compared to the middle and high gradients.

This yeast can grow fast with a high cell density. Its genetic stability, high cell density, and stress resistance make the development process and scale-up of P. pastoris can increase to a scale of 200,000 liters of culture. In contrast to the expensive and complex development of recombinant protein production in mammalian cells, the development of production in P. pastoris is relatively simple and cheaper. The advantage of P. pastoris as an expression system is that it is able to use methanol as a carbon source by inducing the expression of alcohol oxidase oxidase (AOX) enzyme. Promoter used by this enzyme is also used as a strong promoter for the expression of proteins that we want. Unlike in bacterial and mammalian systems, recombinant protein production in Pichia cells is not contaminated with endotoxins or viruses so it is safer and simplifies the downstream processes in bioproduction. The level of endogenous protein in the low supernatant allows Pichia to cultivate with a high volumetric productivity, therefore the process of protein production becomes very economical. This review provides an overview of several things that must be considered in utilizing P. pastoris as an expression system including the selection of vectors, strains, vector integration mechanisms into the genome, glycosylation processes, and applications in industry.","PeriodicalId":280065,"journal":{"name":"BERITA BIOLOGI","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122594071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
