Abstract

Isolation and Selection of Antagonis Bacteria as an Alternative Control of Strawberry Wilt Diseases Strawberry (Fragaria sp.) is a plant that can produce fruit and a members of Rosaceae familia that entered Indonesia in the 1980s and began cultivativated in Candi Kuning Village, Bali at 1983. The farmer reported in 2017 at Candi Kuning Village, Bali, there are many strawberries plants are exposed to wilting disease caused by Fusarium oxysporum which can decreased strawberry production up to 80%. The purpose of this study is to find alternatives ways of chemical control that can cause environmental damage. Biological control, especially the use of antagonistic bacteria, has potential as a replacement because it is much more environmentally friendly and can create sustainable agriculture. The method used are isolation and selection, in vitro inhibitory test, and hypersensitive test on tobacco plants. Research activities included (1) sampling, (2) Fusarium oxysporum isolation from symptomatic strawberry plants, (3) isolation and selection of antagonistic bacterial candidates, (4) antagonistic candidate bacteria inhibitory test against Fusarium oxysporum by dual cultur method in vitro, and (5) hypersensitive test of antagonistic bacterial candidates on tobacco plant leaves. The result of this research is Fusarium oxysporum successfully isolated, obtained 24 candidates of antagonistic bacteria and only 4 candidates of antagonistic bacterial isolates capable of well inhibiting the development of Fusarium oxysporum with the average inhibitory percentage are more than 60 % which is the best inhibitory percentage of 90.17 % and in the hypersensitive test, the bacterial candidates tested were non-pathogenic to the plant.

Abstract

Analysis of Unda Watershed Perfomanced Based on Land Use and Water Discharge Indicators The Unda watershed has experienced a decline in forest area, a decline in water catchment areas, an increase in residential areas and is known to have potential flooding. If the function of a watershed is disrupted, the hydrological system will be disrupted. The purpose of this study was to analyze changes in land use, water discharge and to know the performance of the Unda watershed which includes the precentage of vegetation cover, coefficient of flow regim and annual flow coefficient. The research method is descriptive comparative, by comparing the two parameters, namely the land use and water discharge in 2007, 2011 and 2016. The results showed that land use in Unda watershed were dominated by fields, forests, paddy fields, gardens, shrubs, settlement and open field. During the 2007-2016 period, the highest water discharge occurred in November 2016 amounting to 7.78 m3/sec while the lowest water discharge occurred in March 2011 amounting to 1.72 m3/sec. The results of watershed performance analysis based on indicators of percentage of vegetation cover indicate that the Unda watershed is at a medium level of damage and tends to deteriorate with a range of values ??of 41.42 - 22.63%, while in the flow regime coefficient indicator and annual flow coefficient, indicates that the Unda watershed is at a medium level of damage. The flow regime coefficient value of the 2007-2016 period is at a value of 9.81 - 1.65, then the annual flow coefficient value is at the value of 0.17 - 0.36%. Further research needs to be done regarding the assessment of watershed performance based on other indicators so that the performance of the Unda watershed is known from all aspects.

Abstract

The Effect Of Liquid Fertilizer Concentration On Growths Of Leaf Cuttings Begonia Rex "Silver Circle" Begonia is one of the large genera in the Angiosperm group with asymmetrical leaf characteristics that are very suitable for ornamental plants. "Silver Circle" is the most popular type of Begonia rex. To ensure the availability of Begonia plants in large quantities, there is a need for propagation and cultivation. The success of plants propagation by cuttings is influenced by various factors, namely the type of cuttings and environmental factors including temperature and light humidity and nutrients from the growing media. The quality of planting media can be improved by functional microbial liquid fertilizer. Liquid fertilizer containing microbes functional can produce nutrients and growth hormones that can support plant growth. This study aims to determine the effect of liquid fertilizer concentration given, and also to determine the optimal liquid fertilizer concentration on the growth of B. rex leaf cuttings "Silver Circle". The treatment of liquid fertilizer gave significantly different results from controls on the parameters of leaf area and plant height. The most optimal dose of liquid fertilizer is 300 mL/L.
