Judul: Kajian Stok Ikan Kuniran Upeneus moluccensis (Bleeker, 1855) di Perairan Selat Sunda yang didaratkan di PPP Labuan, Banten
Abstrak: Goldband goat fish is a demersal fish that has an economically important value in Sunda Strait and it is one of fish catches dominant ashore on PPP Labuan. High of demand of this fish, it was feared that populations of fish will decline due to man activities arrest conducted continously. So conducted a study to assess the Goldband goat fish stock in gulf of Sunda Strait to determine the fish alternative management more appropriate and sustainable. The study was conducted from June to October 2013 with each sampling interval approximately 20 days. Primary data collected were the total length, wet weight, gonad maturity, sex, and weight of fish gonads surgically. Goldband goat fish were dominant caught gonad maturity I and II. The growth pattern was allometric negative. Goldband goat fish female have a growth coefficient (K) is 0.17 per year and for manly is taller 0.13 per year, so females have a longer life. The rate of exploitation of goldband goat fish to 0.73 so that suspected goldband goat in Sunda Strait have overexploited.

Judul: Kajian Stok Ikan Kuniran (Upeneus sulphureus, Cuvier 1829) di Perairan Selat Sunda, Banten
Abstrak: Ikan kuniran (Upeneus sulphureus) merupakan ikan demersal sebagai komoditas tangkapan utama di Selat Sunda yang masih banyak dimanfaatkan. Penelitian ini bertujuan untuk menganalisis stok ikan kuniran sebagai dasar pengelolaan agar pemanfaatannya dapat dilakukan secara optimal dan berkelanjutan. Pengambilan contoh dilakukan secara acak berlapis berdasarkan panjang ikan pada bulan Mei-Oktober 2018 di PPP Labuan, Banten. Hasil penelitian menunjukkan nisbah kelamin ikan kuniran adalah 1,00:1,09. Pola pertumbuhan ikan kuniran adalah allometrik negatif dan isometrik untuk masingmasing jantan dan betina. Distribusi frekuensi panjang berkisar antara 71-162 mm. Nilai dugaan L∞ ikan jantan 200,0 mm dengan nilai K sebesar 0,26, sedangkan ikan betina memiliki nilai dugaan L∞ sebesar 172,5 mm dengan nilai K sebesar 0,31. Pola rekrutmen ikan kuniran memiliki dua puncak. Laju mortalitas total ikan jantan 1,95 dan betina 1,40. Laju eksploitasi ikan jantan sebesar 0,81, sedangkan ikan betina sebesar 0,70. Ukuran pertama kali tertangkap kuniran lebih kecil dibandingkan ukuran pertama kali matang gonad. Pemanfaatan ikan kuniran di Selat Sunda mengalami growth overfishing.

Judul: Sistem Pengklasifikasian Entitas pada Pesan Twitter Menggunakan Ekspresi Regular dan Naïve Bayes
Abstrak: The widespread use of social networks like Twitter encourages some institutions to find out the entities that are discussed and the sentiment toward the entities. This research aims to build a system that can extract entities in tweets and classify the sentiment from the tweets. Entity extraction process is done using regular expressions. Writing regular expressions can capture the diverse entities. Sentiment classification is performed using naïve Bayes classification with Multinomial and Bernoulli models. Sentiment in this research consists of three classes, namely positive, negative, and neutral. Before entering the classification, tweets are normalized by replacing the non-standard words with the standard ones. The test results show that regular expression is quite effective for the entity extraction process. As for the results of the classification, naïve Bayes method produces high accuracy (96.75% for Multinomial and 96.33% for Bernoulli). However, the accuracy obtained depends on the neutral class which amounts to 97.88% for Multinomial and 99.95% for Bernoulli, while the positive class are 85.66% and 33.13% and negative class are 33.67% and 0%.
