Abstract

Application of Geographic Information System for Study of Water Table Fluctuations and Characteristics of Aquifers in the South Denpasar District The water needs of the population in South Denpasar District vary greatly depending on community activities. The population and activities of the community that need clean water continue to increase, on the other hand the PDAM of Denpasar City is only able to meet the clean water needs of the population of 46.06% (PDAM Kota Denpasar, 2017). People who have not yet connected PDAM services use ground water as an alternative to making dug wells or bore wells. Excessive use of ground water and exceeding safe discharge will affect groundwater degradation. The purpose of this study was to determine groundwater fluctuations and aquifer characteristics.The method used is a field survey method and quantitative descriptive using ArcGIS 10.4 software. The results showed that the dry season water table depth ranged from 0,8 to 5 m and the rainy season ranged from 0,5 to 3,9 m with groundwater fluctuations ranging from 0.04 to 1,3 m. The direction of groundwater flow from the north to the south with degree N 183o E. A good aquifer is composed of medium-sized sand material, and medium sized brown sand material. Limited aquifers are composed of weathered meosen limestone and sea coral with a discharge of 5-10 liters/second.

Abstract

ABSTRACT Isolation and Identification of Rhizobacteria from Peanut Rhizosphere to Control Fusarium Wilt on Tomato Tomato is one of the important horticultural in Indonesia. One obstacle in the cultivation of tomato is wilt disease caused by Fusarium oxysporum f.sp. lycopersici. Naturally soil microorganisms have the potential to suppress the development of pathogens in the soil. Population of microorganisms around rhizosphere is higher than not in rhizosphere both in quantity and quality. Legumes are known have positive effect to the microorganims in the soil due to rich N from root exudates.The purpose of this research is to determine the ability of rhizobacteria that were isolated from the rhizosphere of peanut in controlling F. oxysporum f.sp. lycopersici causes Fusarium wilt disease. Rhizobacteria as antagonist agent isolated from the rhizosphere of peanut from 3 places and tested against F. oxysporum f.sp. lycopersici in vitro and in vivo. Identification rhizobacteria with Oxoid Microbact GNB Kit.In this study, 61 isolates obtained from the rhizosphere of peanuts. However, only 4 isolates could inhibit Fusarium oxysporum f.sp. lycopersiciin vitro and only 2 isolates could identified certainly. One isolate identified as Klebsiella pneumoniae and one isolate as Stenotrophomonas maltophilia with percentage of probability above 90%. There needs to be more research on the stability of rhizobacteria in suppressing the occurance Fusarium wilt disease on tomato. Keywords: Tomato, Fusarium, and Rhizobacteria.
