Abstract

Effect of Calcium Chloride Concentration (CaCl2) and Storage Temperature on Physico-Chemical of Salacca zalacca Fruit This study aims to know the effect of calcium chloride (CaCl2) and determine the best concentration of calcium chloride and storage temperature on physico-chemical salak fruit. The research method used was split plot design which consisted of two treatments that are concentration of calcium chloride (CaCl2) (sub plot) with four levels; 0%, 9%, 12% and 15% storage temperature (main plot) with two levels; 28±2oC and 15± 2oC. The observation included weight loss, hardness, respiration rate, total dissolved solids, total acid content, vitamin C content, pH test, organoleptic test and shelf life. The result showed that storage of salak fruit with application of calcium chloride had the lowest respiration rate at temperature 28±2oC and 15±2oC. The treatment had the lowest respiration rate was concentration of calcium chloride 12% with the lowest respiration rate ( 2,54 ml/kg.hour of O2 and 2,45 ml/kg.hour of CO2). The concentration of chloride at 12% and storage at temperature 15±2oC was the best treatment to maintain physico-chemical characteristics with parameters wight loss, hardness, total dissolved solids, total acids content, pH test, and shelf life. Organoleptic test showed that a combination of concentration of calcium chloride 12% with storage temperature of 15±2°C have a level of acceptance that are favored by panelists. Calcium chloride of 12% extended the shelf life of salak fruit for 7 days at 28±2oC and 11 days at a temperature 15±2oC, respectivly.

Abstract

ABSTRACT The Test of Natural and Synthetic Fungicides Effectiveness in Controlling Fusarium Wilt of Tomato Plants Caused by Fusarium oxysporum f.sp. lycopersici Fusarium wilt caused by Fusarium oxysporum f.sp. lycopersici is one of important diseases in tomato plants. The emersion of the disease can result in huge loss for farmers. The use of synthetic fungicides that has been widely utilized all this time by farmers to control diseases caused by Fusarium oxysporum f.sp. lycopersici has adverse environmental impacts, therefore it is required biological fungicide that is more environmentally friendly. This study is purposed to testing the effectiveness of some natural fungicides and synthetic fungicide, is like a betel leaf, Trichoderma harzianum fungus, Klebsiella pneumoniae, and benomyl for suppress F. oxysporum f.sp. lycopersici and restrained Fusarium wilt diseases . The result of this study shows that the biological fungicide of betel leaf extract can inhibit the pathogenic F. oxysporum f.sp. lycopersici by 76.11 % and the percentage of inhibition potency of other benomyl fungicides reaches 61.11 % , while Klebsiella pneumoniae is by 54.42 % , and 20.98 % for Trichoderma harzianum on PDA medium. The result of field test shows that the extract of betel leaf can suppress Fusarium wilt by 5 % , T. harzianum , benomyl and K. pneumoniae are able to suppress Fusarium wilt respectively by 2.5 %. The use of T. harzianum and K. pneumoniae as biological control has the same effectiveness with synthetic fungicide in order to suppress Fusarium wilt.   Keywords: fusarium wilt, fusarium oxysporum f.sp. lycopersici, biological fungicide
