Judul: Kinerja produksi ikan rasbora galaksi Danio margariratus dengan media bersalinitas berbeda pada kisaran suhu 28- 30°C
Abstrak: Penelitian ini bertujuan untuk menentukan salinitas media pemeliharaan ikan rasbora galaksi (Danio margariratus) yang menghasilkan kinerja produksi ikan yang baik pada kisaran suhu 28-30°C. Penelitian ini menggunakan rancangan acak lengkap dengan perlakuan 0, 2, 4, dan 6 g L-1 yang masing masing perlakuan diulang sebanyak tiga kali. Ikan rasbora galaksi yang digunakan memiliki panjang rata-rata 1,12±0,05 cm dan bobot rata-rata 48,2±0,01 mg yang dipelihara selama 40 hari dengan sistem pergantian air. Hasil penelitian menunjukkan bahwa perlakuan salinitas berpengaruh nyata terhadap kinerja produksi ikan rasbora galaksi (P < 0,05), yakni kelangsungan hidup maksimal dicapai sebesar 100% pada salinitas 1,95 g L-1, Nilai laju pertumbuhan spesifik maksimal sebesar 2,65% pada salinitas 3,18 g L-1, pertumbuhan panjang mutlak memiliki nilai maksimal sebesar 1,08 cm pada salinitas 2,73 g L-1, koefisien keragaman panjang minimum sebesar 2,89% pada salinitas 2,35 g L-1, dan rasio konversi pakan minimum sebesar 4,12 pada salinitas 2,58 g L-1 memiliki respon kuadratik. Salinitas yang baik untuk pemeliharaan ikan rasbora galaksi berkisar 1,95- 3,18 g L-1.

Judul: Optimasi Salinitas untuk Kelangsungan Hidup dan Pertumbuhan Benih Ikan Tengadak Barbonymus schwanenfeldii
Abstrak: Environmental manipulation techniques are required to increase survival rate and growth of fishes, salinity manipulation is one of them. Salinity directly affects the living organisms life especially in survival rate and growth rate because it is strongly related with their osmoregulation process. The purpose of this research was to determine the optimum salinity for survival rate, growth, and economic profit for nursery activities of tinfoil barb (Barbonymus schwanenfeldii). This research consisted of four treatments of media salinity: 0 ppt (A), 2 ppt (B), 4 ppt (C), and 6 ppt (D). The rearing of tinfoil barb in different salinities showed significant effects on survival rate. Different salinity treatments also showed significant difference on specific growth rate of tinfoil barb.The optimum salinity for tinfoil barb was 4 ppt showed by the highest survival rate at 90%, highest specific growth rate at 1,65%, and highest profit achieved for nursery activities at Rp 139.002 with R/C ratio at 1,12.

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.
