UJI TAPIS ISOLAT KHAMIR FILOSFER SEBAGAI AGENS BIOKONTROL PATOGEN ANTRAKNOSA PADA PISANG, Colletotrichum musae (Berk. dan Curt.) Arx.
No full textABSTRACTColletotrichum musae (Berk and Curt.) Arx. is a pathogen that causes anthracnose disease in bananas. Biological control is an alternative because it is friendly to the environment and reduces the negative impact of synthetic pesticides. The objective of this study was to obtain yeast isolates from bananas potentially used as biocontrol agents. The research was conducted at the Laboratory of Faculty of Agriculture Faculty of University of Tanjungpura Pontianak from September 2017 to February 2018. All the obtained yeast isolates were tested as antagonistic potential against C. musae through dual culture method and viability test of conidia C. musae. The hypovirulent test of yeast isolates that have potential as biocontrol agents are carried out on cucumber. The isolation result obtained 9 isolates of yeast. Based on antagonistic test, yeast isolates had inhibition between 53,42-78,67%. Viability test of conidia C. musae on media that has been shed in yeast cells as much as 106 cells/mL one day earlier showed that conidia still germinate 97.5-100%. Calculation of Severity Index of Disease in hypovirulent test for all isolates of yeast showed 0%. Keywords: antagonist, Colletotrichum musae, hypovirulen, spore germination, yeas
PERTUMBUHAN SETEK LADA SATU RUAS PADA BERBAGAI KOMPOSISI TANAH ALUVIAL DAN KOMPOS TANDAN KOSONG KELAPA SAWIT
No full textThis study aims to obtain the composition of alluvial soil and oil palm empty fruit bunches (OPEFB) compost that provides the best growth of pepper cuttings. This research was conducted in Parit Demang village, South Pontianak. This study start from February 25th, 2018 to May 25th, 2018. This study used an experimental method with a Complete Randomized Design pattern (CRD) it’s a dose of OPEFB compost with 4 levels treatment, each treatment consists of 6 replication and consisting of 10 sample plants. The first treatment alluvial soil composition : OPEFB compost (1:0), second treatment alluvial soil composition : OPEFB (1:1), third treatment alluvial soil composition : OPFB compost (1:2) and fourth treatment alluvial soil composition : OPEFB compost (1:3). Variables observed is: percentage of live seed (%), shoots length (cm), number of shoots per plants (unit), number of leaves (strand), roots volume (cm3), dry weight of shoots (gram) and dry weight of roots (gram). Based on the results of research on the composition of alluvial soil media: 1:2 OPEFB compost and alluvial soil media: 1:3 OPEFB compost gives the same good growth on pepper cuttings. The composition of alluvial soil media: 1:2 OPEFB compost is more effective because it does not require a lot of OPEFB compost so that it can be used in the pepper cutting nursery.

Research conducted at the Desa Parit Canggek snapper Kubu Raya regency in West Kalimantan. The method used in this research is of split plot design using randomized complete block. The treatment consists of the main plots (lime) with three levels (k1 = 0,8 kg /subplot is equivalent to 1 ton/ha, k2 = 1,6 kg /subplot equivalent of 2 ton/ha and k3 = 2,4 kg/subplot equivalent to 3 ton/ha) and subplots (varieties) with 2 levels (v1 = Sukmaraga and v2 = Bima 7), thus there are six treatment combinations, each treatment replicated 3 times. The variables observed in this study were plant height, dry weight, cob length, cob diameter, cob weight, weight of 1000 seeds and dry seed weight/plot. The results showed that the lime and the interaction of lime and varieties maize was not significant effect to all the variables of observation, whereas varieties have significant effect on plant height, dry weight of the upper part of plant, cob diameter, weight of 1000 seeds but there is no significant effect noticeable to the length of the cob, cob weight and dry seed weight/ plot. Sukmaraga significantly different with the Bima 7 on plant height, dry weight, cob diameter and weight of 1000 seeds. Keywords: Fluvaquents, Lime, Maiz
eksplorasi khamir sebagai agens biokontrol patogen blas dari filosfer daun padi sawah
No full text Blast is important disease of rice, and it caused by Pyricularia oryzae Cav. Synthetic fungicide in plant disease control may have negative impacts, so another alternative is needed. Yeast can used as a biocontrol agent. This research aims to investigate the potential of the yeast from leaf phyllosphere of rice paddy as biocontrol agent against P. oryzae. This research was consisted of yeast exploration, isolation and filtrate antagonistic inhibition essay to P. oryzae, and yeast growth respon due to temperature. Ten isolates successfully obtained and tested as antagonist to P. oryzae. Five isolates, YLP05; YLP07; YLP08; YLP09; YLP10, have percentage inhibition more than 30% at 3 dai (day after incubation) dan more than 50% at 7 dai, but their filtrate had not shown any inhibition activity. The five isolates had been formed colony on 1st day at 30°C. Based on diameter and percentage of forming colony, the optimal temperature is different for each yeast isolates. Four isolates which can still grow at 20-40oC those are YPL05, YLP07, YLP09, and, YLP10
