Limbah dari proses etching PCB yang dihasilkan bersifat toksik karena memiliki pH yang sangat rendah dan kandungan logam berat Cu yang tinggi. Dampak negatif dari limbah etching PCB ini yaitu dapat menghilangkan kesuburan tanah, merusak nutrisi tanah dan mencemari air, serta meracuni makhluk hidup sekitar. Dalam penelitian ini, metode biologi digunakan untuk melakukan remediasi limbah proses etching PCB. Bioremediasi limbah proses etching PCB ini dilakukan dalam sistem lumpur aktif. Sumber lumpur aktif berasal dari tanah sawah yang kaya akan massa mikroorganisme. Penelitian ini bertujuan mengetahui efektifitas pengolahan limbah secara biologi dalam mengurangi toksisitas limbah, meliputi pH dan kandungan logam berat Cu, serta mengetahui isolat bakteri yang dapat memperbaiki kualitas limbah cair proses etching PCB. Tahapan penelitian ini meliputi inkubasi limbah selama 7 hari dalam sistem lumpur aktif dengan perlakuan penambahan limbah etching PCB dengan konsentrasi logam Cu 50 ppm, 150 ppm, 250 ppm dan 350 ppm, pengukuran parameter pada hari ke-0 dan ke-7, isolasi bakteri, serta analisis data menggunakan software SPSS ver 15.Â Parameter yang diukur adalah kandungan logam berat Cu, pH, TSS, BOD dan COD. Pengukuran logam berat Cu dilakukan menggunakan spektrofotometer direct Lovibond. Setelah 7 hari masa inkubasi, kandungan logam berat Cu, COD, BOD dan TSS mengalami penurunan serta pH mengalami kenaikan. PerlakuanÂ A (50 ppm) mengalami penurunan kadar logam CuÂ yang paling tinggi yaitu sebesar 93,18%, diikuti dengan perlakuan B (150 ppm) dengan penurunan sebesar 81,94%, perlakuan D (350 ppm) dengan penurunan sebesar 31,57% dan perlakuan C (250 ppm) dengan penurunan sebesar 18,09%. Terdapat tiga bakteri indigenus hasil isolasi bakteri yaitu isolat bakteri X, Y dan Z. Hasil karakterisasi bakteri menunjukkan bahwa isolat X, Y, dan Z memiliki bentuk koloni circular, tepi koloni entire, Gram negatif, motil, katalase positif dan indol positif.

A preliminary study on marine snails harvest (Gastropods) has been done in Krakal beach, Yogyakarta, during October to December 2003. Krakal beach has become an under-pressure habitat since tourism industry occurred all over Indonesia. Marine snails have been harvested for over two decade in this area but there is no study regarding this activity yet. This study aims to elucidate the harvesterâ€™s knowledge about simple conservation and activities such as the way of harvesting, the intensity of harvesting and the income generating from harvesting gastropods.

Asian Swallow Bird (Hirundo rustica Linn.) representing one of the type of bird migran which is spread over in almost entire all earth. This Bird type in Java and Bali represent the common winter visitor met in all height. Information of concerning this animal existence in Yogyakarta very minim, last data about existence and amount of Asian swallow bird population in Yogyakarta in reporting in the year 1996 and till now there is no researcher reporting the species existence in Yogyakarta. This Research study about abundance population and distribution Asian swallow bird at season of migration of September 2003 - March 2004 in all region Yogyakarta. Research conducted in all region of Province of Special Region of Yogyakarta consisted by 5 sub-province, that is Sub-Province Sleman, Sub-Province Bantul, Sub-Province Kulonprogo, Sub-Province of Gunung Kidul and Municipality D.I. Yogyakarta. Parameter measured in this research is estimating an abudan of population and location of distribution population. Data intake of is amount of population conducted by direct enumeration, whereas intake of distribution data conducted by noting the name of location and geographical position. Data of result of research obtained in compiling in tables, is later then made by graph of population fluctuation and ploted in map of pursuant to co-ordinate finding of Asian swallow bird individual. To know diffraction resulted by a population enumeration, will be counted with the standard deviation formula. Result of perception indicate that full scale of Asian swallow bird population during a period to migration reach the maximum value equal to 32.579 that happened at third week of November 2003 and amount of biggest population is concentration in jl. K.H. Ahmad Dahlan and jl. Senopati, area Malioboro, Municipality Yogyakarta, that is equal to 28877ï‚± 36,91. Sub-Province Bantul represent the area which is at most met by the Asian swallow bird location.

Primary productivity of Jombor Swamp, Klaten has been assessed in orderÂ to understand its water quality. The method used was using light-dark bottles incubated for 4 hours. Samples were taken between 6-10, 10-14 and 14-18 hour, under the depthÂ 0.2, 1.5, and 3 m. The results showedÂ that productivity in April â€“ 2.4 to 2.17 ppm, May â€“0.6 to 2 ppm, and June â€“2.1 to 3.4 ppm. The regression correlation of the productivity to phytoplankton`s density is y = -0.03 + 0.01 x and r = 0.76, productivity to light intensity is y = -5.04 + 0.01 x and r = 0.63, productivity to water depth is y = 0.56 + 0.12x and r = 0.31,Â productivity to turbidity is y = 1,78 + 0.33x and r = 0.35, productivity to water temperature is y = 1.91 â€“ 0.08x and r = 0.32, productivity to pH is y = 1.39 â€“ 0.71x and r = 0.20,Â and productivity to CO2 content is y = 1.77 â€“ 0.11 and r = 0.29. Based on the overall findings, the water quality condition was classified as eutrophic.

A survey on abundance of Giant Clam in coral reef ecosystem at PariIslandhas not been done long after the first survey on 1984. The survey itself is very important because Indonesian government has been release SK Menteri Kehutanan No. 12/Kpts-II/1987 and PP No. 7. th.1999 that states the giant clam is protected species. Indonesia has seven species of giant clam out of nine species presence in the world, i.e. Tridacna gigas, T.crocea, T. maxima, T. derasa, T. squamosa, Hippopus hippopus, and H. porcellanus (Rohmimohtarto dkk, 1987, Knop, 1996)

Studi Komparasi Keanekaragaman Benthos Di Waduk Sempor, Waduk Kedungombo dan Waduk Gajahmungkur, Jawa Tengah (Short Communication) Jati, Wibowo Nugroho

Selama ini pengelolaan sumberdaya alam hanya didasarkan pada pemenuhan aspek ekonomi serta hubungan yang bersifat fisik (physical interrelationship). Hal ini dapat diperhatikan adanya kecenderungan pengelolaan sumberdaya alam sebatas program konservasi lingkungan fisik seperti hutan, tanah, air dan bukan pengelolaan sumberdaya alam yang bertujuan untuk keberlanjutan sumberdaya alam (natural resources sustainability). Dengan demikian maka dapat dipastikan lambat laun atau cepat akan terjadi degradasi atau penurunan kualitas lingkungan yang pada akhirnya dapat menimbulkan bencana ekologis (Hadisusanto et al., 2003).

A study on sediment texture to the abundance of Polycentropodidae?s larvae has been done in Sermo Water Reservoir, Kulonprogo, Yogyakarta. Samples have been taken in 3 rivers i.e. Ngrancah, Tegalrejo and Sidowayah. Four different depth were assessed i.e. 0 ? 5 m, 5 ? 10 m, 10 ? 15m, and 15 ? 20 m. Result showed that the larvae?s abaundance was hishest in Ngrancah river on depth of 0 ? 5 m with 53 ind/m2 and lowest on Tegalrejo river on depth of 15 ? 20 m with 3 ind/m2. The larvae?s abundance in every depth was characterized by sand texture and its depth.
