Judul: Pengaruh Pemupukan Fosfor dan Umur Potong Awal Terhadap Vigoritas dan Kualitas Alfalfa (Medicago sativa L.).
Abstrak: Hijauan pakan merupakan salah satu faktor penting dalam budidaya ternak ruminansia. Hijauan pakan berkualitas tinggi sebagai salah satu bahan baku ransum ternak ruminansia semakin dibutuhkan mengingat harga konsentrat yang mahal. Salah satu upaya pengadaan hijauan pakan berkualitas tinggi yaitu dengan cara mengintroduksi hijauan yang memiliki kandungan nutrisi yang cukup tinggi, salah satunya yaitu alfalfa tropis. Salah satu prinsip manajemen yang diterapkan pada budidaya hijauan makanan ternak tak terkecuali adalah mengupayakan vigoritas (ketegaran) pertumbuhan awal yang prima, sebagai basis pertumbuhan kembali (regrowth) yang kuat ketika dilakukan pemanenan berkali-kali dalam jangka waktu yang panjang.

Judul: Pengaruh Pemupukan dan Pemberian Urin Sapi Terhadap Pertumbuhan dan Tingkat ProduktivitasMedicago sativa L
Abstrak: Medicago sativa L (Alfalfa) is one of kind legume comes from Iran (Cheeke 2005). This research was conducted to measureeffect of fertilized with manure and urin of cattleforgrowth and production of alfalfa with same value of nitrogen where was tried in Ciwidey, Bandung. This research used Randomized Complete Design (RCD) with 5 treatments and 3 replications. The treatment were P1 (NPK (control) 15 g m-2), P2 (manure of chicken 0.33 kgm-2), P3 (manure of cattle 1 kgm-2), P4 (manure of chicken 0.17 kgm-2+ urine 0.3 litersm-2), and P5 ( manure of cattle 0.5 kgm-2+ urine 0.3 litersm-2). The observation was the response of plant which include presentage of seed, plant height, total leaf, as feed and dry matter of leaf and stem, crude protein and crude fiber. The result showed that the treatment of iso nitrogen which fertilized with manure and urin of cattle is not significant togrowth and productivity of alfalfa. Another result of this reaserch is the treatment P4 (manure of chicken 0.17 kgm-2+ urine 0.3 litersm-2) can subtitution NPK and showed the better growth, productivity and crude protein of alfalfa than NPK treatment.

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%.
