Judul: Tingkat cekaman dan pertumbuhan mule duck (Mandalung) yang diauskan pada umur sehari dan disuplementasi Viyamin C
Abstrak: Mule duck (mandalung) merupakan hasil persilangan antara entok (Cairina moschata) dengan itik alabio (Anas platyrynchos). Mule duck memiliki keunggulan antara lain ukuran tubuh yang hampir sama antara jantan dan betina, pertumbuhannya cepat, persentase karkas yang tinggi dibanding tetuanya, kadar lemak daging yang rendah, kandungan gizi yang tinggi dan penghasil hati. Namun Mule duck juga memiliki beberapa kelemahan antara lain mudah stres (nervous) dan mempunyai sifat agresif. Debeaking (pengausan paruh) diduga dapat mengurangi sifat agresif. Sifat mudah stres (nervous) akan meningkatkan persentase heterofil (heterofilia), menurunkan persentase limfosit (limfopenia), meningkatkan rasio H/L dan terganggunya pertumbuhan. Vitamin C yang sudah dikenal sebagai antistres dan antioksidan diduga dapat mengatasi stres (nervous) pada Mule duck. Dengan suplementasi vitamin C diharapkan persentase heterofil menurun, persentase limfosit meningkat sehingga rasio H/L menurun serta pertumbuhan meningkat. Dari uraian tersebut, maka perlu diadakan penelitian untuk mengatasi sifat agresif dan mudah stres (nervous) pada Mule duck untuk meningkatkan pertumbuhan. Penelitian ini menggunakan rancangan acak lengkap pola faktorial 2x3x4 (Steel dan Torrie 1995), faktor pertama: tanpa pengausan (A) dan pengausan umur sehari (A₁), faktor kedua tanpa suplementasi vitamin C (Bo), suplementasi vitamin C 500 ppm (B₁) dan suplementasi vitamin C 1000 ppm (B2). Setiap perlakuan diulang empat kali. Satu satuan percobaan menggunakan satu ekor Mule duck. Debeaking dilakukan pada umur sehari dengan cara meletakkan paruh pada permukaan pisau debeaker. Vitamin C diberikan mulai umur sehari sampai 10 minggu dengan mencampurkannya dalam air minum. Parameter yang diamati meliputi persentase heterofil, persentase limfosit, rasio heterofil/limfosit, bobot badan (BB) dan pertambahan bobot badan (PBB) tiap minggu serta laju pertumbuhan spesifik (LPS). Hasil penelitian menunjukkan bahwa debeaking pada umur sehari tidak berpengaruh nyata tehadap parameter yang diamati. Suplementasi vitamin C berpengaruh nyata (P<0,05) terhadap PBB umur 3 minggu, PBB umur 6 minggu, LPS 3 minggu, LPS 6 minggu serta berpengaruh sangat nyata (P<0,01) terhadap PBB umur 2 minggu dan LPS umur 2 minggu. Interaksi antara debeaking dan suplementasi vitamin C berpengaruh nyata (P<0,05) terhadap PBB 9 minggu dan LPS 9 minggu.

Judul: The Performanee of Mule Duck with Different Level Addition of Kangkung (Ipomoeae aquatica) in Ransum.
Abstrak: Stress is easily happen on mule duck because it has high nervous characteristic like its dam. Stress will reduce mule duck performance and one of solution to handle stress is by giving antistress or transquilezer. Kangkung is one of water pland and it can be use as transquilezer so it is appropiate to be used antistress medicine for mwe duck. Kangkung have content protein, fat, cartbohidrat, calsium, phosphor, iron, vitamin A, B I, C, caroten, sitosterol and hentriacontan which are needed for body and to increase mule duck performance. This experiment purpose are to study whether kangkung performance also to find the right kangkung suplementation dosage to increase mule duck perfonnance as meat ripe. This experiment was done in September up to November 2002 in Laboratory of Science Produce Livestock Poultry Block B, Department of Science Produce Livestock. Faculty Of VeterinaIy, Bogor Institute of Agriculture. This experiment used 80 mule duck with age of 5-10 week without unsexed, commercial feed and kangkung. This experiment used complety randomized design with four treatment with the level 0%, 5%, 10% and 15%. Every treatment consistfor repetation so it were obtained 16 unit research and every reseach unit consist five mule duck. The variable which were observed are feed consumption. body weight, body weight grow, feed convertion and Income Over Feed and Duckling Cost. Data were analized with anova and continued with Fisher's lest significant different. The experiment of varian analyzed shows that kangkung suplementation in feed significantly influenced into final body weight, body weight grow, but this not significantly influenced for feed consumption during this research. Kangkung suplementation 15% gives the best feed convertion which is 3,62 and give the highest Income Over Feed and Duck Cost. Keyword: mule duck, kangkung (Ipomoea Aquatica), performance, ransum

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%.
