The land to get goat feed is getting narrower. Feed fermentation technology is a simple technique that can provide a solution to help the farmers in Samigaluh district. The purpose of this study is to evaluate the effect of fermented feed on weight gain of female Etawah (PE) goat breeds and to find out the optimum amount of fermented feed. Material of fermented complete feed: Calliandra, Mahogany, Cacao, Rambutan, Jackfruit, Cassava leaves and wheat bran (polar). All ingredients were fermented using comercial inoculum (EM4) with molasses and enough water. The treatments of fermented feed was carried out on 6 female PE goats aged 1-2 years and were divided into three groups for three types of treatment. The fermented complete feed contained the following nutrients: dry matter 39.52%, organic matter 90,42%, ash 8.99%, crude protein 11.44%, ether extract 3.6%, crude fiber 22.94% and nitrogen free extract 53,04%. The results showed that PE goats fed with forage 50% and fermented feed 50% tended to have a higher average body weight gain compared to 100% forage and 100% fermented feed, as much as 2.5 kg after 1 month trial. The treatment of 100% fermented feed does not seem to provide a significant weight gain, because the PE goats in this study are accustomed to being given forage from birth and never being given fermented feed thus affecting the amount of fermenteed feed consumption.Infrastructure development and land corversion have a direct negative impact on goat farmers in Samigaluh district.

In relation to the tested glass composite, modal analysis was performed by help of special measuring device Pulse 12. The mentioned device was supplied by company Bruel & Kjear and the experimental measurements were carried out using damaged and undamaged plate sample which were prepared from the mentioned material hereinbefore. The investigated and analyzed plates of glass composite were made of six layers of glass fibres and they were arranged under the angle 90° (it is like fabric material made off glass fibres). The layers arranged in the given way were joined by epoxide resin MGS 285. The experimental measurement of natural frequencies of glass composite plates was carried out using the undamaged and damaged sample with proportions 78 mm x 78 mm while ten measurements were performed for each one specified site of the sample. In relation to the damaged plate sample, there was the circular cut-out with the diameter 6 mm in the centre. The finite element method in the software system ADINA v.8.6.2 was used for numerical analysis of the natural frequencies. According to the comparison of frequency response for undamaged and damaged sample, it can be concluded that the natural frequency of the damaged sample is less than the natural frequency of the undamaged sample. The measurement range for frequencies was up to 14 000 Hz.","PeriodicalId":20577,"journal":{"name":"PROCEEDINGS OF THE 2ND INTERNATIONAL CONFERENCE ON BIOSCIENCE, BIOTECHNOLOGY, AND BIOMETRICS 2019","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79770939","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}

Kuntze, is a tuberous plant having high starch content similar to potatoes. This plant is now still under-utilized, grows limited only in some coastal area in Indonesia. In addition to their use as source of carbohydrate, secondary products of this plant are useful as anticancer. Genetic improvements of plants can be done by mutation with Gamma irradiation. In vitro shoots of Tacca have been developed after irradiation with Gamma ray. The aim of this research was to investigate growth, phytochemical properties and antioxidant activity of Tacca plantlets after Gamma irradiation treatment. Shoots were irradiated with 5, 20 and 30 Gy, then they were grown on MS medium containing 0.5 mg/l BAP or 0.5 mg/l kinetin. Growth was recorded every week from week-1 to week-8 of culture. After 8 weeks of culture, biomass production of plantlets, phytochemical properties as well as antioxidant activity were determined. The results showed that irradiated plants had slightly lower in growth compared to the control plants. However, IC50 of irradiated plants was lower than control plant. This indicated that irradiated plants had higher antioxidant activity. Addition of kinetin and BAP affected IC50 value. Irradiated Tacca has similar phytochemical properties of control plants based of alkaloid, flavonoid, steroid, saponin and tannin detection. This study showed new opportunities to produce a new superior type of T. leontopetaloides with higher antioxidant activity induced by Gamma irradiation mutation.","PeriodicalId":20577,"journal":{"name":"PROCEEDINGS OF THE 2ND INTERNATIONAL CONFERENCE ON BIOSCIENCE, BIOTECHNOLOGY, AND BIOMETRICS 2019","volume":"97 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82797954","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}
