Judul: Kinerja Produksi Ikan Sinodontis Synodontis eupterus Ukuran ¾ Inci dalam Sistem Resirkulasi dengan Padat Penebaran Berbeda
Abstrak: air tawar yang banyak diminati oleh para pecinta ikan hias. Permintaan pasar yang tinggi belum dapat terpenuhi karena produktivitas dari ikan ini masih tergolong rendah. Penelitian ini bertujuan menentukan produksi terbaik ikan sinodontis Synodontis eupterus pada padat penebaran 1.000, 3.000, dan 5.000 ekor m-2 yang dipelihara dalam sistem resirkulasi, tiap perlakuan diulang sebanyak tiga kali. ikan sinodontis yang digunakan memiliki panjang rata-rata 1,85±0,02 cm dan bobot rata-rata 0,25±0,09 gram. Ikan dipelihara selama 50 hari dan diberi pakan pelet komersial setiap hari pukul 07.00 dan pukul 18.00 WIB, pakan diberikan sebanyak 5% dari bobot ikan. Benih ikan sinodontis dipelihara dalam akuarium berukuran 30 cm x 25 cm x 30 cm. Hasil penelitian menunjukkan bahwa produksi terbaik terdapat pada padat penebaran 5.000 ekor m-2 dengan nilai kelangsungan hidup yaitu 85,27±0,71% laju pertumbuhan spesifik yaitu 4,66±0,24%, dan berdasarkan perhitungan analisis usaha padat penebaran 5.000 ekor m-2 menghasilkan keuntungan paling tinggi yaitu Rp 136.502.798.

Judul: Pertumbuhan dan kelangsungan hidup benih ikan Sinodontis Synodontis eupterus pada kepadatan yang berbeda
Abstrak: In a good environmental condition and adequate quantity of food, an increase of stocking density will increase yield. This experiment was aimed to obtain information about the most optimum stocking density of sinodontis nursery culture. The initial size of sinodontis fry was 2,54+0,11 cm in length and 2,97+0,43 g in weight, which was obtained from a sinodontis farmer at Pagelaran, Bogor, West Java. Prior to experiment, the fry was adapted in the aquaria with a size of 60x29x33 cm which had been filled with 20 ℓ of water. The fry was then cultured at 3 different stocking density treatments. 3, 6, 9 fry/ℓ with 3 replications for a period of 40 days. The fry fed a Limnodrilus sp. twice a day at satiation. Substitution of water exchanged twice a day in the morning and on the afternoon with a rate of 2x30% a day. The result indicated that stocking density did not significantly affected fish survival, specific grow rate, growth of absolute length and coefficient of variation (p>0.05). But when viewed from the economic efficiency, density of 9 fry/ℓ give the best results with the R/C ratio is greatest.

Judul: Addition of preposition word graph generator module in bogor_delft_construct application
Abstrak: Knowledge graph is a new method used to analyze text and represent in a graph form. Word graph consists of concept and relation which represents the meaning of a word in a graph form. Ontology used in a word graph structure consists of 8 binary relationships, 4 frame relationships, and a focus. Bogor_Delft_Construct is an application that implements knowledge graph method to analyze text written in Bahasa Indonesia, However, this application still has some limitations in analyzing vocabularies such as prepositions. This research aims to add a module to the application that could generate word graph of preposition based on preposition patterns prosposed by Wulan (2009). The addition of preposition word graph generator module that was done in Bogor_Delft_Construct could recognize 23 prepositions which were followed by its auxiliary words. The preposition’s auxiliary words were divided into 12 documents; each has different nominative meaning.
