Abstract

Potato (Solanum tuberosum L.) is one of the five basic sources of carbohydrates. It consumed by many people world spreads. One of the constraints in potato production is the presence of fungal diseases. Fungi that cause diseases in potato crops include Phytophthora infestans which causes late blight, Fusarium oxysporum which cause fusarium wilt, Alternaria solani Sor. which cause brown spot disease, and Aspergillus niger which infect bulbs and produce aflatoxin. Identification of potatoes-contaminating fungi can lead the farmers to get a better potatoes production. This research goal is to identify potatoes-contaminating fungi in traditional market of Condong Catur, District of Sleman, Yogyakarta. This research was using descriptive method with laboratory examination. We took 30 defected potatoes suspected of being infected by fungi. Samples were taken from eachpotato aseptically and then cultured in Saboraud’s Dextrose Agar (SDA) media. Observation was held for the fungi growth after 24 hours incubation. From the laboratory examination, there were fungal infections in all of potatoes and identified as Phytopthora infestans (26.67%), Fusarium oxysporum (86.67%), Alternaria solani Sor. (6.67%), and Aspergillus niger (13.33%). Phytophthora infestans, Fusarium oxysporum, Alternaria solani Sor., and Aspergillus niger identified as potatoes-contaminating fungi in Traditional Market of Condong Catur, District of Sleman, Yogyakarta.Keywords: contaminant, fungi, potatoes

Abstract

Several rivers flow across Daerah Istimewa Yogyakarta (DIY includes Opak River which it’s upstream located on Merapi Volcano area. The river has a lot of biological resources, includes prawns. Freshwater prawns (Macrobrachium spp.) has important role in maintaining the balance of freshwater ecosystems. The purpose of this research was to determine species diversity of Macrobrachium spp. and to understand the morphological and molecular characters of them. Phenetic similarity was analyzed using 74 morphological characters, ISSR1 and ISSR3 primers. The results were analyzed using a program MVSP 3.1 (Multi- Variate Statistical Package) to obtain a dendogram that showed both intra-and interspecies similarity of Macrobrachium spp. Six species of Genus Macrobrachium were identified, they are Macrobrachium pilimanus, M. sintangense, M. lanchesteri, M. cowlesi, M. latidactylus, and M. equidens. Both morphological and molecular analyses show two major clusters with the similarity of 55.6% for morphology and 21.52% for molecular. Based on morphological and molecular characters analysis, we concluded that phenetic similarity of Macrobrachium spp. in Opak River was affected by the morphological structure of the second pereiopod, habitat type, size and number of eggs, as well as the type of larval development.Keywords: characters, Macrobrachium, molecular, morphology, Opak River
