Abstract

The study aimed to investigate the use of wood sawdust as a medium for growth and the optimum addition ratio of plantation wastes that can increase the yields and quality of white oyster mushroom (Pleurotus ostreatus). This research used Completely Randomized Design (CRD) consisting of 7 levels of treatment ratio of  wood sawdust and plantation wastes. The data analysis involved one way ANOVA followed by Duncan’s 5%. The results showed that the wood sawdust can be used as growing medium, and the addition of plantation wastes can increase the yields and the quality of white oyster mushroom. The addition of cocoa and coffee wastes with a ratio 25% was the optimum ratio treatment which increased the number of fruiting bodies, caps diameter, production weight, Biologycal Eficiency Ratio (BER) and protein, fats, carbohydrates and fiber content in white oyster mushrooms. It is recommended to be applied because both treatments would increase the yield and quality of white oyster mushroom.Keywords: cocoa and coffee pods wastes, wood sawdust, yield and quality of white oyster mushroom

Abstract

Wadi is a sort of the local wisdom of Dayak ethnic at Central Borneo as the effort of food warranty when fish could be found easily or when others  sources of protein, i.e.meat is difficult to be found. Wadi is a fermentation food made from fish or meat processed traditionally by mixing the fish or the meat with salt and “lumu” (fried rice without oil),  then preserved for several days until a special aroma and taste were formed,with salty and acid taste with strong aroma. The changes of the taste and aroma of the wadi is caused by fermentation process  formed during the preservation. The effort to create the wadi as a local wisdom is need to be continued.Keywords: food warranty; local wisdom; traditional food Wadi
