Fecal Egg Count Reduction Test (FECRT) is one of the methods to measure of anthelmintic resistance of gastrointestinal helminth. The objective of this paper is to know gastrointestinal helminth resistance using Fecal Egg Count Reduction Test. A community trial was carried out in North Lombok during Mei 2019. Eighteen (18) Bali cattle were used in this research after analyzed by eggs per gram feces (EPG) to know the value of eggs of helminth in Bali cattle before anthelmintic were given, as basic data. They were divided into 3 groups: group one was not given anthelmintic, group two was given Ivermectin (0.2 mg/kg BW), and group three was given Albendazole (15 mg/kg BW). The feces of 18 Bali cattle examined by EPG to know of Fecal Egg Reduction were collected after 14 days of giving Ivermectin and Albendazole. The data of Fecal Egg Reduction between Ivermectin and Albendazole groups were analyzed by T-test. The result showed that the group given Ivermectin can be reduced 91.66±83.20 % eggs per gram feces and the group was given Albendazole can be reduced 83.81±74.51% eggs per gram feces by FECRT. The T-test showed no significant difference between the group that was given Ivermectin and albendazole group (p>0.05). The eggs per gram feces of the group were not given anthelmintic increased until 41.66±208.366 eggs per gram feces. Ivermectin and Albendazole can give for gastrointestinal helminthiasis because they can reduce eggs per gram feces but anthelmintic resistance of Ivermectin and Albendazole was indicated because the anthelmintic has to reduce fecal egg count by at least 95 %.Anthelmintic resistance (AR) is increasing worldwide as a consequence of the over usage of anthelmintic.

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}
