Judul: Produktivitas Pendederan Ikan Pink Tail Characin Ukuran ¾ inci dengan Sistem Pergantian Air Setiap Hari
Abstrak: The study was aimed to determine the water exchange proportion to achieve optimalize seed productivity of pink tail characin fish rearing. The average size of fish was 2.37 cm or weight of 0.03 ± 0.01 g/fish. The fish were reared at density of 2 fish/L in each aquariums at volume of 100 liters. The treatments consisted of exchange water at proportion of 25%, 50%, 75%, and 100% per day with 3 replicates. The results showed the highest survival rate, average length and daily growth rate of 75% exchange water treatment that were 99.83±0.29%, 2.75±0.02 cm, and 3.98±0.12% respectively. The highest length coefficient of diversity, feed efficiency and economic benefit were obtained by daily exchange water at proportion of 75% these were 4.79±0.19%, 12.12±0.19% and Rp 985 417.- respectively. The optimal rearing productivity of ornamental fish pink tail characin size ¾ inch was in the 75% of daily water exchange proportion.

Judul: Produksi Pendederan Ikan Ctenopoma Ctenopoma acutirostre Pada Padat Tebar Berbeda Dan Pergantian Air 30%.
Abstrak: This study aimed to determine the optimal stocking density on fish nursery ctenopoma at size of 2 cm and 30% water changes every day. The treatment in the study was 4 levels of fish stocking densities, ie 2, 4, 6 and 8 fish/liter and quality of the culture media was maintained by replacing the water as much as 30%. Fish reared in 12 aquariums filled with 10.5 liters of fresh water respectivelly and as long 40 days period. The average length of fish seed used was 2.18±0.18 cm. During the rearing, the fish fed with tubificid worm in the morning, noon and night. The results showed that the difference of the treatment did not affect the survival and the coefficient of variance, however increasing the stocking density flollowed by lowering the growth rate, and the feed efficiency. Considering economic value, the highest rearing productivity was achieved by stocking density of 6 fish/liter.

Judul: Perencanaan lanskap permukiman untuk mitigasi Bencana gempa bumi Kecamatan Pangalengan Kabupaten Bandung
Abstrak: Indonesia adalah negara kepulauan yang terletak diantara beberapa patahan lempeng benua yaitu lempeng Eurasia dan lempeng Filipina di sebelah utara, lempeng Australia di bagian selatan, dan lempeng Pasifik di bagian timur kepulauan. Hal ini mengakibatkan Indonesia menjadi salah satu kawasan dengan zona seismic tertinggi di dunia. Pada tanggal 2 September 2009 terjadi gempa bumi berkekuatan 7,3 Skala Richter dengan episentrum yang berada di Samudera Indonesia di sebelah selatan Tasikmalaya. Gelombang gempa merambat hingga Bandung, Cianjur dan Sukabumi. Salah satu kawasan yang terkena dampak paling parah akibat gelombang gempa ini adalah Kecamatan Pangalengan di Kabupaten Bandung. Berdasarkan data statistik Badan Nasional Penanggulangan Bencana, Kecamatan Pangalengan mengalami kerusakan paling parah dari total 29 kecamatan yang ada di Kabupaten Bandung. Selanjutnya dari 13 desa yang ada di Kecamatan Pangalengan, hampir semua bangunan di desa-desa tersebut mengalami kerusakan akibat gempa termasuk sarana infrastruktur penting seperti Puskesmas dan sekolah.
