Get PDFTitle : Study on The Potency of Soil Microbes Isolated from Andisols of Dieng, Central Java, as S-Oxidizing Biofertilizer Inoculant. The problem of nutrient deficiences tend to increase, including sulfur deficiency. The use of high purity NPK fertilizers stimulate sulfur deficiency in agricultural land. This problem can be corrected by the use of elemental sulfur accompanied with S-oxidizing biofertilizer. The study aimed to evaluate the potential of sulfur oxidizing microbial isolated from Andisols of Dieng Central Java as S-oxidizing inoculant. Andisols Dieng naturally contains high sulfur that allegedly inhabited many sulfur-oxidizing microbials. The research consisted of two experiments, each arranged in completely randomized design (CRD). Each experiment consist of two factors namely the kind of microbial isolated from Andisols Dieng and incubation time. The first experiment used Czapek-dox+elemental sulfur medium, while the second experiment used vermicompost as medium. The observed variables include soluble-S, bacterial density, biomass of fungi and medium pH. One isolate of bacteria (I1)and three isolates of fungi (F1, F2 and F3) taken from Andisol of Dieng showing their ability to oxidize sulfur in Czapek-dok agar medium. They were used as isolates in the experiment. The result of the first experiment showed that the oxidized sulfur increased with the length of incubation time as indicated by the increase of soluble-S, bacterial cell density or fungi biomass in the medium followed by the decrease of pH. The second experiment showed that the population of bacteria or fungi isolates and soluble-S of vermicompost were increased collaterally with incubation time. The fungi isolate of F2 have the highest potency as inoculant of S-oxidizing biofertilizer as shown by it ability to survive, grows and oxidize S both in Czapek-dox+elemental sulfur liquid medium as well as in vermicompost medium.Masalah kekahatan hara cenderung meningkat, termasuk kekahatan sulfur. Penggunaan pupuk NPK berkemurnian tinggi ikut mendorong terjadinya kekahatan hara di lahan pertanian. Masalah kekahatan hara ini dapat diatasi melalui penggunaan sulfur elementer yang disertai denngan pupuk hayati pengoksidasi sulfur. Penelitian bertujuan untuk mengkaji potensi mikrobia pengoksidasi sulfur yang diisolasi dari tanah Andisol Dieng, Jawa Tengah sebagai inokulan untuk pupuk hayati. Tanah Andisol Dieng secara alamiah mengandung sulfur yang cukup tinggi sehingga diperkirakan dihuni oleh banyak mikrobia pengoksidasi sulfur. Penelitian terdiri dari dua percobaan, masing-masing disusun dalam rancangan percobaan acak lengkap dua faktor, yaitu macam isolat mikrobia hasil isolasi dari Andisol Dieng dan lama inkubasi. Percobaan pertama menggunakan medium cair Czapek-dox + sulfur sedangkan percobaan kedua menggunakan medium vermikompos. Tiap-tiap kombinasi perlakuan diulang tiga kali. Variabel yang diamati meliputi jumlah S terlarut, kerapatan sel bakteri atau biomassa jamur dan pH medium. Dari hasil eksplorasi diperoleh satu isolat bakteri I1 dan tiga isolat jamur F1, F2 dan F3 yang menunjukkan kemampuan mengoksidasi sulfur pada medium Czapek-dox+ sulfur elementer agar. Hasil percobaan menunjukkan bahwa proses oksidasi sulfur meningkat seiring dengan bertambahnya waktu inkubasi yang ditunjukkan oleh meningkatnya jumlah S-terlarut, kerapatan sel bakteri atau biomassa jamur dan menurunnya pH medium. Hasil serupa diperoleh dari percobaan kedua. Isolat jamur F2 menunjukkan potensi yang paling tinggi sebagai inokulan pengoksidasi sulfur yang ditunjukkan oleh kemampuannya tumbuh dan mengoksidasi sulfur yang paling tinggi baik pada medium cair Czapek-dox + sulfur maupun pada medium vermikompos
