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 Â wood sawdust and plantation wastes. The data analysis involved one way ANOVA followed by Duncanâs 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 mushroomÂ Â Â

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 othersÂ 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 âlumuâ (fried rice without oil),Â 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 processÂ 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

Abstract. Wadi is a sort of traditional foods that made of fish from Dayak tribe in Central Kalimantan. Wadi is made by the addition of salt and lumu. People make wadi as a supply of side dishes during difficult seasons of fish and stock for farming, hunting, or collecting forest products. In wadi, there are several bacteria species that capable in degrading amylum and protein. The bacteria capability in amylum and protein degradation can be determined by calculating the hydrolysis index. The aims of this study are to: (1) identify the amylolytic bacteria and proteolytic bacteria species from wadi, (2) determine the amylum and protein hydrolysis index on each amylolytic bacteria and proteolytic bacteria species isolated from wadi, and (3) determine the amylolytic bacteria and proteolytic bacteria species that have the highest hydrolysis index. This research is descriptive explorative research. The research results showed that: (1) there were four isolates of amylolytic bacteria isolated from wadi, i.e: Enterobacter agglomerans, Pseudomonas fluorescens, Acinetobacter baumannii, and Micrococcus varians, and there were five species of isolated proteolytic bacteria from wadi, i.e: Enterobacter agglomerans, Pseudomonas fluorescens, Nitrococcus mobilis, Acinetobacter baumannii, and Micrococcus varians, (2) the amylum hydrolysis index of Enterobacter agglomerans is 3.77; on Pseudomonas fluorescens is 3.00; on Acinetobacter baumannii is 4.16; and on Micrococcus varians is 7.23. The protein hydrolysis index of Enterobacter agglomerans is 3.22; on Pseudomonas fluorescens is 2.25; on Nitrococcus mobilis is 1.67; on Acinetobacter baumannii is 3.42; and on Micrococcus varians is 3.45, (3) Micrococcus varians has the highest amylum, i.e:Â 7.23 and protein hydrolysis index is 3.45.Keywords: hydrolysis index, amylolytic bacteria, proteolytic bacteria, wadi.

Abstract. Wadi is a sort of fermented fish product from Dayak tribe in Central Kalimantan. Wadi is made with the addition of lumu, sugar, and salt, and fermented for 7-10 x 24 hours. During the fermentation process, there are microflora from fish, and microflora from lumu that play a role in fermentation process. Some species of bacteria that play a role in the wadi fermentation process are lipolytic bacteria and Lactic Acid Bacteria (LAB). This research aims to: (1) identify the species of lipolytic bacteria and LAB that present in the wadi, (2) determine the lipid hydrolysis index and lactic acid clearance zone index of lipolytic bacteria and LAB that present in the wadi, and (3) determine the species of lipolytic bacteria and LAB which have highest ability to hydrolyze lipid and have the highest ability to produce lactic acid based on lipid hydrolysis index and lactic acid clearance zone index. The results showed that, (1) there are four species of lipolytic bacteria and LAB present in wadi: Lactobacillus coryniformis, Lactobacillus casei, Nitrococcus mobilis and Streptococcus lactis; (2) the four species of bacteria haveÂ different lipid hydrolysis index and lactic acid clearance zone index which are Lactobacillus coryniformis has a lipid hydrolysis index of 1.63 and lactic acid clearance zone index of 3.31; Lactobacillus casei has index of 1.94 and 3.96; Streptococcus lactis has index of 1.51 and 1.54 and Nitrococcus mobilis has index of 0.98 and 1.52; (3) Lactobacillus casei is a species of lipolytic bacteria and LAB which has the highest ability to hydrolyze lipid and to produce the highest lactic acid based on the lipid hydrolysis index and lactic acid clearance zone index, which are 1.94 and 3.96. Keywords: lipolitic bacteria, LAB, lipid hydrolysis index, lactic acid clearance zone, wadi.

Citrinin is a sort of mycotoxin which caused mycotoxicosis. Citrinin is produced by Penicillium citrinum mold that canÂ contaminate sort of food especially damaged beans. Â Citrinin is known as nephrotoxic as well as hepatotoxic mycotoxinÂ and caused hepatocite structure damage. This research was done: 1) to know the effect of citrinin to hepatocite structureÂ damage; 2) to know the effect of citrinin dose difference to the value of the hepatocyte structure damage; 3) to know theÂ effect of citrinin to the value of hepatocyte structure damage on three zones of hepar lobulus. The samples of thisÂ research were male mice (Mus musculus) var. BALB-C Â at the age of three months. The experiment group of Â mice wasÂ orally administered with citrinin in three doses, i.e: dose-1: 1 mg/kg BW; dose-2: 1,75 mg/kg BW; dose-3: 2,5 mg/kg BW.Â Hepatocyte structure damage is observed on centrilobular zone, midzone, and perifer zone. The hepatocyte structureÂ damage examination is done by histopathologycal andultra structural examination by electron microscope.

Some endophytic fungi species live in medicinal plant tissue and does not make any damage, but live in symbiotic mutualism relationship with the host plant. This research was done to: 1) identify the endophytic fungi species isolated from P. angulata leaf, twig, and stem bark tissues, 2) determine the endophytic fungi colonization in the P. angulata plant tissue by histologic observation. The endophytic fungi was isolated from healthy P. angulata plant parts, then inoculated on Potato Dextrose Agar medium and incubated in 27°C for 7-14 days. Each endophytic fungi isolates were identified. The histologic observation was done by microscopic observation to determine the endophytic fungi position in the plant tissue. The conclusion are: 1) seven endophytic fungi species were found: Penicillium verrucosum, Colletotrichum alienum, Fusarium subglutinans, Aspergillus nidulans, Mycelia sterilia 1, Mycelia sterilia 2, and Rhizoctonia sp.; 2) the endophytic fungi micelium was found on the leaf epidermis cell wall, on the twig epidermis cell wall, and parenchyma cell wall, on the stem bark epidermis cell wall. The suggestion of the study: it is need to make the next research about secondary metabolites content produced by endophytic fungi species isolated from P. angulata and their antimicrobial activity.
