Abstract. Mursyidin DH, Nazari YA, Daryono BS.2017. Tidal swamp rice cultivars of South Kalimantan Province, Indonesia: A case study of diversity and local culture. .Traditional rice (Oryza sativa L.) cultivars may become an indispensable part of the local culture and traditions of rice-growing people across Asia over many generations. The existence of this germplasm in the tidal swamp area of South Kalimantan Province, Indonesia has been observed morphologically and showed a close relationship with the local culture. A total of forty (40) traditional rice cultivars with different morphological characteristics have been found in this country, and still preserved sustainable by the local farmers along with their local culture and traditions. The tradition of 'wadai 41' may become a good example for this relationship. In this tradition, some traditional foods are made by the local people and use some of the local rice as basic ingredients. This information may be useful as guidance for conservation and rice breeding programs in the future.

Batik coloring waste contains heavy metal chromium (Cr), and other components such as, Sulfide (S2-), Ammonia (NH3), phenol and oil-fat. The Batik industries are generally classified as small and medium enterprises, which usually do not process their waste. The aim of this study was to observe the ability of Aspergillus sp. 3 to reduce the concentration of Cr, sulfide, ammonia, phenol, and oil-fat component from batik wastewater. The selected fungus, Aspergillus sp. 3 was isolated from batik waste. Based on previous study, selected fungus, Aspergillus sp. 3 was able to decolorize and remediate Indigosol Blue batik wastewater. Potato dextrose broth medium was used for growing the mycelium. Reduction process was occurred with omitted of medium (formed mycelium-supplemented the batik wastewater). Based on experiments, Aspergillus sp. 3 was able to reduce 89.09%, 83.05%, 56.37%, 48.48%, 95.09%, 32.56, 39.28 and 38.15% of Cr sulfide, NH3, phenol and total oil-fat concentration, respectively. Aspergillus sp. 3 had potential application in bioremediation of water polluted by batik wastewater.

Thirty-seven isolates of endophytic fungi were isolated from leaves and stems of Calopogonium mucunoides collected from PTPN PTPN XII (Persero) Rubber Plantation, Klatakan, Kecamatan Tanggul, Kabupaten Jember, Jawa Timur. All isolates were identified based on morphological characteristics using the light microscope. The 37 isolates of endophytic fungi are members of Deuteromycota and Basidiomycota and classified to genera Phoma, Phomopsis, Corynespora, Rhizoctonia, Helicosporium, Curvularia, Torulomyces, Gliocladium, Gloeosporium, Acremonium, Tripospermum, Aureobasidium, Colletotrichum, Humicola, Fusarium, Sclerotium, and sterile hyphae.
