Abstract

Endophytic fungi are fungi that live and associate in host plants and have the potential to produce secondary metabolites that are the same as their host. Utilization of endophytic fungi as a solution reduces the use of a lot of biomass to produce the desired secondary metabolites. This study aims to explore and identify endophytic fungi found on lime leaves obtained from Kalpataru plantation, Denpasar, Bali. Endophytic fungi were isolated from samples of young and mature leaves that were fresh, not wilted or yellow, and disease free. Fungal isolation was carried out by direct planting method on Potato Dextrose Agar (PDA) media at room temperature (27oC), and the incubation time was 3-7 days. Re-isolation was carried out to obtain pure cultures, then the endophytic fungi were identified by observing the morphological characters macroscopically and microscopically, then compared with identification books. The results obtained were eight isolates, and six isolates were identified belonging to the genera Fusarium, Colletotrichum, Aspergillus, Penicillium, and 2 isolates were not identified (sterile mycelia). Endophytic fungi found on young leaves, namely Aspergillus and Colletotrichum, on mature leaves, namely Fusarium, Aspergillus, and Penicillium. Keywords: endophytic fungi, lime, sterile mycelia, PDA

Abstract

Research on the quality and status of irrigation water has been carried out for lowland rice in the Subak of Yehembang, Jembrana Regency, Bali. The sampling technique was carried out by Purposive Sampling. The analysis was carried out for physical, chemical and microbiological parameters. The level of feasibility of the results are matched with class 1 Water Quality Standards based on the Bali Governor Regulation No. 16 of 2016, while the status of water quality is determined by the Storet Method based on the Decree of the Minister of Environment No. 115 of 2003. The results showed that in the rainy and dry seasons there were 3 parameters namely DO, BOD5, and Coliform Bacteria pass grade 1 water quality standards. For the quality status of Subak yehembang irrigation water for 4 locations during the rainy and dry seasons all are classified as moderately polluted Keywords: subak, irrigation water, water quality, water quality statu.
