Judul: Optimasi osmolaritas media dan hubungannya dengan respon fisiologis benih ikan baung (Hemibagrus nemurus)
Abstrak: This experiment was conducted to determine osmolarity and its relation with physiological responses (osmotic gradient, oxygen consumption levels, blood glucose level, protein retention, energy retention, feed efficiency, growth and survival rate) of Hemibagrus nemurus fry. The experiment used aquarium sized 50x35x30 cm, the number are twelve, each aquarium contain 30 l of water equipped with circulation pump, filter, heater and closed with black plastic. This experiment is completely randomized design with four different treatment and three replications. Thirty fish with induvidual mean body weight of 2.5±0.05 g, were fed upon the experimental diets five times a day at satiation, for 40 days. Observation parameters were osmotic gradient, oxygen consumption levels, blood glucose level, protein retention, energy retention, feed efficiency, growth and survival rate of Hemibagrus nemurus fry. The results showed that medium osmolarity (salinity) has significant influence to physiological responses of Hemibagrus nemurus fry. Medium osmolarity of 6 ppt was the best result that expressed by osmotic gradient (0.062±0.007 Osmol/kg H2O), oxygen consumption level (0.47±0.03 mg O2 /g/hour), blood glucose level (38.20±0.47 mg/100 ml), protein retention (25.73±1.50%), energy retention (28.73±0.61%), growth (4.09±0.07%) and feed efficiency (70.64±0.80%). While the survival rate responses to medium osmolarity given same influence.

Judul: Effect of Different Salinity on Physiological  Response and Growth of Bonylip barb (Osteochilus vittatus)
Abstrak: Salah satu faktor lingkungan yang dapat memengaruhi perkembangan benih ikan air tawar adalah tekanan osmotik media yang dinyatakan dalam bentuk parameter salinitas, karena salinitas berpengaruh terhadap kelangsungan hidup dan pertumbuhan benih ikan. Penelitian ini bertujuan menganalisis efek salinitas terhadap respon fisiologis, kelangsungan hidup dan pertumbuhan benih ikan nilem (Osteochilus vittatus). Rancangan percobaan yang digunakan berupa rancangan acak lengkap (RAL) dengan tiga kali ulangan pada setiap perlakuan salinitas yang berbeda, yaitu 0 ppt, 2 ppt, 4 ppt, 6 ppt, dan 8 ppt. Penelitian ini menggunakan benih ikan nilem berukuran 5,43±0,01 cm dan 1,89±0,02 g. Hasil penelitian ini menunjukkan bahwa salinitas 0 sampai dengan 8 ppt dapat ditoleransi oleh benih ikan nilem dan berpengaruh terhadap parameter pertumbuhan. Selama waktu pemeliharaan, diperoleh perlakuan terbaik yaitu pada salinitas 4 ppt dengan pertumbuhan bobot mutlak sebesar 0,90 g, pertumbuhan panjang mutlak sebesar 0,68 cm, tingkat pertumbuhan spesifik sebesar 1,79%, dan tingkat kelangsungan hidup sebesar 100%. Salinitas media di atas 4 ppt mengakibatkan ikan mengalami stres yang ditunjukkan dengan meningkatnya kadar kortisol., One of the environmental factors that can affect the development of freshwater fish seeds is the osmotic pressure of the media which is expressed in the form of a salinity parameter, because salinity affects the survival and growth of fish seeds. This study aims to analyze the effect of salinity on physiological responses, survival and growth of Bonylip barb (Osteochilus vittatus) seeds. The experimental design used was a completely randomized design (CRD) with three replications for each different salinity treatment, namely 0 ppt, 2 ppt, 4 ppt, 6 ppt, and 8 ppt. This study used Bonylip barb seeds measuring 5.43 ± 0.01 cm and 1.89 ± 0.02 g. The results of this study indicate that a salinity of 0 to 8 ppt can be tolerated by Bonylip barb seeds and affects growth parameters. During the maintenance period, the best treatment was obtained at 4 ppt of salinity with an absolute weight growth of 0.90 g, an absolute length growth of 0.68 cm, a specific growth rate of 1.79%, and a survival rate of 100%. Media salinity above 4 ppt causes fish to experience stress as indicated by increased cortisol levels.

Abstrak: Perkembangan kota Jakarta dari waktu ke waktu sangatlah cepat, sehingga menyebabkan kota-kota tua banyak yang tergusur untuk dijadikan daerah baru yang lebih modern. Apabila hal tersebut tidak ditanggulangi secara dini maka keberadaan Kota Lama Jakarta akan hilang. Hal inilah yang melatar belakang untuk dilakukan tindakan perlindungan dan revitalisasi kawasan bersejarah Sunda Kalapa.
