Abstract

Leather industries contribute significant problems due to the hazard wastes, that threat to environmental sustainability and to human health. The negative impacts are particularly caused by the chemical compounds used in the conventional process of the leather tannery, such as lime, sodium sulphide, chrome, etc. Enzyme is protein compound from biological system, that acts as catalyst (bio-catalyst). Enzyme can be used to replace partly or complete the chemicals used in tannery processes. Recently, micro-organisms are considered a appropriate device to produce enzymes. Furthermore, it is necessary to select potential micro-organisms for enzyme production.“Exolite”, that is first enzyme produced in pilot scale in Indonesia, proved to reduce significantly pollutant in waste of leather tannery industries. Therefore, the development of enzyme industry in Indonesia is needed to be supported.

Abstract

Jangari is an area in Cirata reservoir that was developed for tourism area. Lately, in this area have been developed many cages for fish culture that produce organic waste in huge number. This research was conducted to know the status and dynamics of water quality in Jangari that receive organic waste in huge number.The research revealed that Jangari water body could be cited as an eutrophic water body. This conclusion was due to (i)-the concentrations of phosphorus was always higher than 0,016 mg•l-1P and nitrogen total was always higher than 0,711 mg•l-1N; (ii)-the density of fitoplankton in 25 cm depth was between 36.590•103 and 40.710•103 ind•l—1; whereas in 150 cm depth was between 29.620•103 and 36.370•103 ind•l—1. This phytoplankton community was dominated byCyanophyta (70,9%-78,2%), especially. Microcystis sp and Oscillatoria sp. (iii)-the vanishing point of secchi disc was always smaller than 71 cm. During the research zooplankton was dominated by copepoda, cladocera and rotifera with density fluctuate between 34-394 ind•l—1. The eutrophic status for Jangari, will threaten the sustainable potency for tourism area; and therefore it was suggested to built one management for Cirata reservoir which could be hoped to plan, do and evaluate the development of Cirataappropriate to the potencies and carryng capasity of reservoir.

Abstract

Pupuk organik granul (POG) berbahan baku limbah padat organik, banyak diproduksi untuk memacu petani agar mau menggunakan kembali pupuk organik, sehinggga kualitas dan produktivitas lahan pertanian dapat ditingkatkan, khususnya kandungan C-organiknya. Kualitas POG sendiri dapat ditingkatkan dengan menambahkan pupuk hayati, agar populasi mikroba fungsionalnya meningkat. Pada bahan organik yang sudah atau dalam proses dekomposisi diketahui sudah mengandung mikroba fungsional. Penelitian ini dilakukan dalam rangka mengetahui keberadaan populasi mikroba fungsional pada POG, khususnya bakteri pelarut fosfat dan penambat N2, sebelum dan setelah diperkaya dengan pupuk hayati. Hasil penelitian menunjukkan tingginya populasi bakteri pelarut fosfat dan penambat N2 yang terlibat dalam proses dekomposisi bahan organik, dan mikroba tersebut tetap ada walaupun bahan organik tersebut telah diproses lanjut menjadi POG. Rentang nilai populasi bakteri pelarut fosfat pada POG sebelum diperkaya pupuk hayati sebesar: 2,7X106-4,7X107 cfu/g, dan untuk bakteri penambat N2 sebesar: 4,2X108-2,2X1010 cfu/g. Nilai tersebut sudah memenuhi kriteria POG yang diperkaya dengan pupuk hayati. Secara populasi total, penambahan pupuk hayati pada POG, tidak mengindikasikan adanya peningkatan populasi bakteri pelarut fosfat dan penambat N2 yang secara alamiah sudah ada di POG.Kata kunci: limbah padat organik, pupuk organik granul, pupuk hayati, mikroba fungsional, populasi mikroba.

Abstract

Daerah tangkapan (DAS) Citarum hulu mempunyai luas sekitar 177.100 ha, meli-puti kota Bandung dan kabupaten Bandung yang terletak di danau tua. Sungai Ci-tarum selain kegunaannya sebagai buangan limbah pabrik dan penduduk disekitar sungai, juga berfungsi sebagai penggerak listrik dan perikanan (jarring apung) di waduk Saguling dihilinya. Oleh karena kompleksnya pemanfaatan sungai ini, maka diperlukan suatu pendekatan pengelolaan di DAS Citarum tersebut. Penelitian ini tujuannya adalah untuk memperbaiki kualitas sungai Citarum dengan pendekatan simulasi model, yaitu simulasi-simulasi pengelolaan DAS Citarum. Penetapan model dengan tiga sub-model yaitu, hidrograf aliran, debit beban (COD, BOD, T-N, T-P, and NH3), dan polutegraf aliran dengan model tangki. Model dikalibrasi dari debit serta kualitas air harian sungai Citarum yang terukur di stasion Nanjung .Dari model kelihatan hidrograf dan polutograf aliran, cendrung sama antara model den-gan pengukuran, sehingga model layak untuk pendugaan pemasukan beban yang kualitas sungai masih baik pada debit minumum. Dari hasil simulasi agar kualitas-nya tetap terjaga, maka beban masukan dari industri terutama tekstil dan pemuki-man sebaiknya dikurangi (treatment) sekitar 85 % untuk COD, BOD dan T-P dan 45 % untuk NH3 dan T-N untuk pemukiman pada kejadian debit minumum
