Sulfur Oxidizing Bacteria

The acidophilic iron and sulfur oxidizing bacteria were isolatedfrom black water ecosystem, an 'extreme' ecosystemaffected indirect or directly by peat land Isolation and selection were done on minimal media (liquid and solid). All selectedstrain of bacteria (BB 179, OM 349, AH 41, TB 23, TB 27, TP 3, NN 323, and SI 188) were identified as Thiohacillusferrooxidans. Biooxidation and bio-leaching tests were accomplished using the isolated bacteria. The results showed thecapability of the isolated bacteria to oxidize ferrous-salt and to leach the low qualities of sulfide ores.

The objective of this experiment was to evaluate the abili!y of bacteria strains isolated from black water ecosystem of Central Kalimantan in degrading crude oil and diesel oil. The experiment was conducted at the Laboratory of Soil Biology, Department of Soil Sciences, Faculty ~f Agriculture, BogorAgricultural University (IPB). The crude oil degrading ability of bacteria was tested on a minimum liquid medium (Gurujeyalakshmi dan Orial, 1989) and soil. Six crude oil and diesel oil degrading bacteria were isolated. The bacteria were identified as Bacillus panthotenticus (2 strains), B. circulars (1 strain), Pssudomonas diminuta (1 strain), P. stufzeri (1strain) and Klebsiella edwardsii (1 strain). These bacteria were able to degrade crude oil or diesel oil whether in a liquid minimum medium or in soil.On a minimum liquid medium, after 10 days incubation, bacteria were able to degrade 20.49% of the crude oil, while in the Entisol soil, after 7 days of incubation, as high as 40.29% of crude oil was degraded and after 28 days incubation, 64.95 of crude oil had been degraded by selected bacteria.

The regional tectonic conditions of the KSK Contract of Work are located in the mid-Tertiary magmatic arc (Carlile and Mitchell, 1994) which host a number of epithermal gold deposits (eg, Kelian, Indon, Muro) and significant prospects such as Muyup, Masupa Ria, Gunung Mas and Mirah. Copper-gold mineralization in the KSK Contract of Work is associated with a number of intrusions that have occupied the shallow-scale crust at the Mesozoic metamorphic intercellular junction to the south and continuously into the Lower Tertiary sediment toward the water. This intrusion is interpreted to be part of the Oligocene arc of Central Kalimantan (in Carlile and Mitchell 1994) Volcanic rocks and associated volcanoes are older than intrusions, possibly aged Cretaceous and exposed together with all three contacts (Carlile and Mitchell, 1994) some researchers contribute details about the geological and mineralogical background, and some papers for that are published for the Beruang Kanan region and beyond but no one can confirm the genesis type of the Beruang Kanan region The mineralization of the Beruang Kanan area is generally composed by high yields of epithermal sulphide mineralization. with Cu-Au mineralization This high epithermal sulphide deposition coats the upper part of the Cu-Au porphyry precipitate associated with mineralization processes that are generally controlled by the structure

This research used the lesser known species as much 5 types rattan, consisted of i.e marau (Calamus Mettanensis Becc), toho (Calamus Spp), galang (Daemonorops Verticilaris Griff Mart), hijau (Calamus Spp) and simpurut (Calamus Panajuga Becc) from Central Kalimantan. Preservative used the mixture of boric acid with the borax and copper-8 by  the concentration of 1,0 %, 2,0 % and 3,0 %. Soaked time during 2 day, 4 day and 6 day by immersion chilled. Result of research indicated that the retention value varied, the greater of concentration condensation and soaking period, the greater average the value of retention while penetration result at all of treatment showed the value 100 %.Keywords:  rattan, preservation, retention, penetration, cold soaking.

Sanitasi merupakan salah satu faktor bagian yang terpenting dalam kehidupan dan juga merupakan suatu kebutuhan dasar dalam kehidupan sehari-hari bagi manusia. Aturan-aturan yang telah dibuat oleh pemerintah tidak pernah diperhatikan lagi sehingga kualitas lingkungan tidak terjaga dan menyebabkan lingkungan kita tercemar dengan limbah. Air limbah dapat berasal dari rumah tangga (domestik) yaitu buangan kakus (black water) berpotensi mengandung mikroba pathogen dan air bekas cucian dapur, mesin cuci dan kamar mandi (grey water). Melihat kondisi tesebut, limbah rumah tangga sampai saat ini dibuang langsung ke saluran-saluran drainase yang ada melalui parit-parit dan sungai. Buangan air limbah tersebut di tampung melalui bak Instalasi Pengolahan Limbah (IPAL) yang bersifat komunal, off site sanitation atau individual dan selanjutnya lumpur tinja dari bak IPAL tersebut di olah ke Instalasi Pengolahan Lumpur Tinja (IPLT) dengan menggunakan mobil tinja atau motor tinja. Dengan melihat cakupan layanan IPLT yang baru mencapai 5,2%, dapat diduga bahwa 39,06% pengolahan air limbah sistem setempat masih belum efektif. Penelitian ini menggunakan metode deskriptif yaitu prosedur pemecahan masalah yang diselidiki dengan menggambarkan keadaan subjek atau objek dalam penelitian pada saat sekarang berdasarkan fakta-fakta yang tampak atau apa adanya. Penelitian ini difokuskan pada kondisi dilapangan melalui wawancara dan obesrvasi sampai dengan pengolahan. Prakiraan timbulan limbah cair pada 20 tahun kemudian diproyeksikan timbulan/buangan air limbah di Kota Pontianak akan mencapai 79.515 M3/hari dengan debit air limbah mencapai 920 liter/detik, maka diproyeksikan kebutuhan Instalasi Pengolahan Air Limbah Komunal ini di Kota Pontianak mencapai 269 unit dengan layanan kepada sekitar 138.793 penduduk. Sistem penyaluran air limbah cair rumah tangga tersebut ke penampungan dan seterusnya diolah di IPLT yang telah tersedia. Dalam penanganan lumpur tinja di Kota Pontianak dilakukan pengangkutan/penyedotan lumpur tinja, pengolahan lumpur tinja dan penanganan lumpur keringKata-kata kunci: sanitasi, proyeksi, limbah rumah tangga, instalasi pengolahan air limbah komunal, instalasi pengolahan lumpur tinja
