Judul: Analisis Potensi Dan Ketersediaan Air Berdasarkanneraca Air Das Di Das Ciliwung Hulu  (Kasus Tahun 1995, 1996 dan 1997)
Abstrak: Pengelolaan suatu daerah aliran sungai (DAS) dengan baik merupakan sala1l satu earn yang tepat untuk mengatasi masalall kcsenjangan air baik menurut ruang (spasial) dan waktu (temporal). Selanjutnya strategi pengelolaan DAS dapat disusun untuk meningkatkan pemanfaatan keterscdiaan air aktual, salall satunya adalall untuk sektor pertanian. Penyediaan air bagi pengembangan sektor pertanian memerlukan infonnasi potensi keterscdiaan air secara kuantitas, kualitas dan kontinuitas. Informasi tersebut dapat diperoleh melalui analisis neraea DAS. Studi ini dilakukan di DAS Ciliwung Hulu dengan pertimbangan balnva DAS tersebut menghadapi masalall banjir di musim Ilujan dan kekeringan di musim kemarau, sehingga sangat bcsar dampaknya terhadap produksi pertanian di hulu dan keamanan pemukiman di hilir.

Judul: Analisis Potensi Dan Ketersediaan Air Berdasarkan Neraca Air Di Das Brantas Hulu, Jawa Timur (Studi Kasus Tahun 1995,1996 dan 1997)
Abstrak: Air merupakan bahan yang mutlak diperlukan oleh mahluk hidup. Ketersediaan air relatif tetap, sedangkan kebutuhan .akan air cenderung terus meningkat. Hal ini mendorong terjadinya persaingan antar berbagai kepentingan penggunaan air. DAS Bralitas Hulu mempunyai potensi air yang cukup besar sekitar 12 milyar m'itahun dengan curah hiljan rata-rata mencapai 2.000 mmltahun. Namun yang dimanfaatkan hanya sekitar 2,6 - 3,O milyar m3/tahun. Salah satu cara untuk mengetahui potelisi ketersediaan air dapat dilakukan dengan menggunakan metode neraca air.

Judul: Distribution and Diversity of Ectoparasite Mites on Geckos in Indonesia
Abstrak: Data on the diversity and dispersal of parasitic mites on house geckos in Indonesia are very scarce. In this work, the distribution and diversity of mites living on three species of house geckos, namely Cosymbotus platyurus, Hemidactylus frenatus, and H. garnotii collected throughout Indonesia, has been elaborated. Geckos and mites were captured and immediately preserved in 70% ethanol. Whole mount of the mites was prepared by clearing in lactophenol followed by mounting on polyvinyl lactophenol solutions. The SEM preparation was conducted to examine the detail morphological characters of the mites. The results showed that among 448 individuals of geckos, 221 geckos were infected by Geckobia mites. Prevalences of C. platyurus, H. frenatus, and H. garnotii infested by mites were 14.8%, 50.69%, and 79.6%, respectively. Three different spesies of Geckobia (G1, G2, and G3) could be differentiated; and based on similarities of their morphological characters to ones described in published literatures, Geckobia G2 is Geckobia glebosum and Geckobia G3 is Geckobia bataviensis while G1 could not be identified to the species level. The highest mean intensity of Geckobia G1 infestation was found on H. garnotii (I=7.0), G. glebosum infestation on H. frenatus (I=3.5), and G. bataviensis infestation on H. garnotii (I=11.8). In general, C. platyurus was infested by the least number of mites. Geckobia G1 were found living on the skin folds on the claws, G. glebosum were found mainly on the body and thigh, and G. bataviensis were found on almost all parts of the host’s body. Geckobia mites are distributed randomly throughout Indonesian Archipelago, following the pattern of distribution of their hosts. So it is concluded that Geckobia G1, G. glebosum, and G. bataviensis are sympatric.
