Abstract

ABSTRACT Perception and Preference of the Campus Landscape Aesthetic Quality Faculty of Agriculture Udayana University - Jimbaran Bali Generally the Faculty of Agriculture Udayana University Jimbaran Bali landscape has not been organized properly, except around the administration building. Unorganized landscape can be seen from visual quality or the aesthetic. This research aims to know students’ perceptions and preferences about the college landscape aesthetic, especially between organized and unorganized landscape areas. This research used Semantic Differentials measurement methods. The result shows that students’ perceptions of the campus landscape aesthetic based on form and color-scoring criteria are monoton, informal, linear, bright, cold, and secondary color.   Keywords: aesthetic, campus landscape, perceptions, preferences, Semantic Differentials

Abstract

Development Population of Root-Knot Nematode (Meloidogyne spp.) and TheLevel Of Damage to Some Plants Solanaceae Family This research started from November 2018 until March 2019 in the experimental garden Pegok Faculty of Agriculture, University Udayana. It uses acomplete randomized design with 4 treatments and 6 repeats. The study treatmentuses some of the Solanaceae family plants such us tomato (Lycopersiconesculentum), eggplants (Solanum melongena L), large red chili pepper (Capsicumannum), cayenne pepper (Capsicum frutescens), which was given 500 of nematodesMeloidogyne spp. on Each polybag. The observed parameters include thedevelopment of the population of nematode Meloidogyne spp. for 2 life cycles in 1gram of root and 300 grams of soil and measuring the rate of crop damage.Nematodes Meloidogyne spp. is an important parasitic nematodes in the world.Solanaceace plants are widely cultivated in Indonesia because of their high economicvalue and become an important food ingredient. One of the problems in aquacultureSolanaceae is the attack nematodes Meloidogyne spp.. The highest population of theresearch results is in tomato plants with a damage rate of 68.3%. The lowestpopulation amount in chili pepper plants with a damage rate of 11.7%. The less-likedplant Nematoda Meloidogyne spp. is a chili pepper so it can be used as an alternativecrop rotation.

Abstract

Citrus Vein Phloem Degeneration (CVPD) Disease Detection With Polymerase Chain Reaction (PCR) Technique In Citrus Plant Leaves That Have Different Chlorosis Symptom Patterns Detection of Citrus Vein Phloem Degeneration (CVPD) disease with Polymerase Chain Reaction (PCR) on citrus leaves that have different pattern of chlorosis symptoms was conducted at laboratory of Genetic Resources and Biology Molecular, Udayana University. This study aims to determine the presence of Liberibacter asiaticus in citrus leaves that have different patterns of chlorosis symptoms using a specific primer 16S rDNA (OI1 and OI2c). DNA amplified on 1% agarose gel obtained DNA bands of 1160 bp on four samples with a pattern of symptoms of chlorosis.

Abstract

Soil Quality Test and Its Management Directives on Rice Cultivation in Subak Jatiluwih, Penebel, TabananThe purpose of the study was to determine the quality of the soil and the management directives for rice cultivation at the research site. This study used survey methods and soil tests in the Laboratory of Soil Science and Environment. It consists of several stages of survey management of the system by the farmers, the analysis of the soil followed by the determination of the quality of the soil and the direction of management. The result showed that land in the research site has good and medium soil quality. The location which has good qualities was in sample IV, the medium quality was in sample I, II, III, V and VI. The management directives which were recommended for the medium soil quality were the improvement of soil management system. The processor which was recommended in this research was using tractors and livestock. The recommended types of plants were the local and new rice varieties. The recommended straw management was embedded back into the ground. The use of fertilizer which was recommended was the use of urea and SP-36 fertilizers. The recommended land use intensity cropping twice a year.

Abstract

ABSTRACT The study of bacteria isolated from Lapindo mud as a bio-control  agents  against  P. oryzae and bio-stimulant agents in rice plant Rice (Oryza sativa L.) is the staple food of more than 60% of the world’s population. One of the cause for the low productivity of rice in indonesia is the occurrences of rice blast disease caused by Pycularia oryzae . This study was done to evaluate the potential use of  bacteria isolated from Lapindo mud as bio-control  agents  against  P. oryzae and bio-stimulant agents in rice plant. The result showed that three isolate of  bacteria isolated from Lapindo mud namely AA1, 20M14, and ZB11 significantly (P<0,05) inhibited the growth of  P. oryzae on Potato Dextrose Agar (PDA) medium with  inhibitory  activity  varied  85,07%, 86,58%, and 70,82%. Ten isolates of  bacterial  isolated from Lapindo mud significantly improved the growth of rice seedling. In which the plant heigth, number of root, content of chlorophyll in the leaf, number of  lateral  root  length of root, and the fresh and dry weight of plant significantly (P<0,05) higher on treated plant when compared to control. This is result suggested that three isolates of bacteria isolate from Lapindo mud can be further developed as bio-control agents to inhibit the P. oryzae growth and ten isolates of bacteria isolated from Lapindo mud can be used as bio-stimulan agents. Keywords:Bacteria, Pycularia oryzae, Oryza sativa L.

Abstract

The Relationship Between Population of Whiteflies (Bemisia tabaci) (Genemadius) (Hemiptera : Aleyrodidae) with Incident of Yellow Disease on Tomato Plant (Solanum lycopersicum Mill.) in Dusun Marga Tengah, Kerta Village, Payangan District, Bali The disease of tomato is namely yellow disease that is caused by a Geminivirus from species Tomato Yellow Leaf Curl Virus (TYLCV) . That virus can be propagated through the vector that is Bemisia tabaci.This study aimed to know the relationship between population of Bemisia tabaci (Genemadius) (Hemipteraaleyrodidae) with incident of yellow disease on tomato plant (Solanum Lycopersicum Mill.) This study is located at the center of tomato cultivation in Dusun Marga Tengah, Kerta Village, Payangan, Bali from December 2016 to February 2017. This study observe the number of nymphs Bemisia tabaci on tomato plants as sample that choosen and observed the incidence of disease in tomato plant area. Relationship between yellow disease incidence with population of Bemisia tabaci is analyzed by a linear regression model. The results showed that the incidence of yellow disease in tomato plants correlated positively and significant with the increase of vector insect population Bemisia tabaci that is 87,37%.

Abstract

ABSTRACT Host range of Bean Common Mosaic Virus (BCMV) causal agent of mosaic diseases on long yard bean  (Vigna sinensis L.) This objective of the study is order to find out the host range of BCMV and symptom variation. DAS-ELISA (Double Antibody Sandwich-Enzyme Link Immunosorbent Assay) menthod was used in this study. The study consisted of (1) Host range evaluation by mechanical inoculation, (2). Symptom observation on tested plants, (3) Serological test with DAS–ELISA. The result indicated that BCMV can infected Leguminoceae plants (peanuts, long yard beans, and beans); Solanaceae plant (tomatoes); Cucurbetaceae plant (cucumbers); Amaranthaceae plant (spinach); and Balsaminaceae plant (henna flowers). DAS-ELISA analysis shown that those plants were infected by BCMV. The symptoms variation were mosaic, vein banding,  wrinkled, and curved on commercial long yard beans (aura and panah merah varieties); wrinkled on commercial long yard beans (KPK and pusaka hijau varieties), cucumber and spinach; wrinkled and rolled on beans; wrinkled and curved upside on henna flowers.   Key word : bean common mosaic virus ,  long yard beans, DAS-ELISA
