The middle part of the river is frequently utilized as rafting for tourism, such as in Bongkasa Pertiwi Village, Abiansemal District, Badung Regency – Bali. To preserve the river’s ecological function, the information of riparian vegetation as the dynamic component in river is highly required. This research aimed to study the structure of riparian vegetation in Bongkasa Pertiwi Village. The plot method was used and the study site was divided into three stations. Each station was composed by three replications with four plot variations: trees (20 x 20 m), poles (10 x 10 m), saplings (5 x 5), and herbs-shrubs (2 x 2 m). The data was analysed using vegetation analysis that completed with Importance Value (IV), Shannon-Wiener Diversity Index (H’), Index of Dominancy (C), and Index of Evenness (E). This study found that the structure of riparian vegetation in Bongkasa Pertiwi Village was in good condition which was indicated by the high abundance of local tree species. The floristic composition of riparian vegetation comprised by 18 species of trees, 18 species of poles, 21 species of saplings, and 29 species of herbs and shrubs. Cocos nucifera, Pterospermum javanicum, Bischofia javanica, Cananga odorata, Elaeocarpus serratus, Artocarpus heterophyllus, Coffea canephora, and Nephelium lappaceum were the species with the highest Importance Value (IV). The floor vegetation in form of herbs and shrubs was dominated by Sphaegneticola trilobata, Oplismenus burmanni, and Diplazium esculentum. Based on the Diversity Index (H’), Index of Dominancy (C), and Index of Evenness (E), diversity of riparian vegetation in Bongkasa Pertiwi Village was classified as medium category, without any dominated species, and the vegetation composition was equivalent.","PeriodicalId":53348,"journal":{"name":"Jurnal Biologi Udayana","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48302882","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}

Some factors can support the appearance of contamination in feed, especially temperature and humidity. The main objective of this research was to investigate potency of Rhizopus spp. on inhibit A. flavus FNCC6109 in broiler chicken concentrate feed. The experiments were conducted dual culture method and the inhibition test of the Rhizopus spp. filtrate culture was incubated for 3, 4 and 5 days on in vitro. The in vivo test was directly applied in broiler chicken concentrate feed which added Rhizopus spp. filtrate culture concentration at 10% (v/v), 20% (v/v), 30% (v/v), 40% (v/v), dan 50% (v/v). The results showed that the Rhizopus spp. filtrate culture significantly (P?0,05) to inhibit the growth of A. flavus FNCC6109 both in vitro and in vivo. The percentage inhibition of Rhizopus spp. filtrate culture incubated for 5 days showed 67,47±2,10% relatively better results than 3 and 4 days, and therefore was used in the in vivo. Application of 50% (v/v) Rhizopus spp. filtrate culture to the broiler chicken concentrate feed significantly reduced 82% population of A. flavus FNCC6109 after 15 days incubated relative to that of negative control (concentrate feed without addition Rhizopus spp. filtrate culture and A. flavus FNCC6109).","PeriodicalId":53348,"journal":{"name":"Jurnal Biologi Udayana","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43296924","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}
