Judul: Cross Language Question Answering System Menggunakan Pembobotan Heuristic dan Multidokumen
Abstrak: People tend to ask when they need to get some information. This often raises a difficulty whenever available information is not in same the language with the person understands or speaks. Cross Language Question Answering System (CL-QAS) is an information retrieval system that is able to handle this kind of situation. It accepts a question query as the input and outputs the answer in the translated language. In this study, CL-QAS is developed that takes query in Indonesian language and answers in English. The system output is calculated by weighting heuristic and multi-documents. The average time to produce answer is quite fast, i.e. 3.03 seconds. The system accuracy is good considering for the following queries: SIAPA (100%), KAPAN (100%), DIMANA (100%), and BERAPA (90%).

Judul: Implementation of Question Answering System for Document in Bahasa Indonesia with List Question
Abstrak: In the last few years, many studies of Question Answering System (QAS) have been conducted by a number of research groups around the world. Lately, a question is not only presented in the form of factoid questions, but also as a list questions where a question requires more than a single-entity of answer. However, recent development on QAS can only accommodate factoid questions which only require a single-entity's answer. To address this issue, the purpose of this research is to implement QAS for list questions. In order to obtain candidate of answers, heuristic weighting is performed in the passage which is contained on the top n documents. One thousand documents and 40 queries are used in the experiment. The best results of experiment show correctness of 26%, 39%, 36.33% and 70 % for "who", "how many/much", "where" and "when" list questions, respectively.

Judul: Pengaruh media tanam dan panjang Stek daun terhadap inisiasi tunas Muda lidah mertua (sansevieria Trifasciata “lorentii”)
Abstrak: Penelitian ini dilakukan untuk mengetahui pengaruh media tanam dan panjang stek daun terhadap inisiasi tunas muda lidah mertua (Sansevieria trifasciata ‘Lorentii’) yang dilakukan di Kebun Percobaan Leuwikopo IPB Dramaga pada bulan November 2010 sampai Februari 2011. Rancangan percobaan yang digunakan adalah Rancangan Kelompok Lengkap Teracak (RKLT) dengan dua faktor dan tiga ulangan. Faktor pertama adalah media tanam terdiri atas campuran tanah dan pupuk kandang kambing, arang sekam dan serbuk kayu. Faktor kedua adalah panjang stek daun lidah mertua yang terdiri atas 5 cm, 10 cm, dan 15 cm. Hasil penelitian menunjukkan bahwa persentase stek hidup, persentase stek berakar, persentase stek bertunas, panjang akar, jumlah tunas, bobot basah dan bobot kering tunas tertinggi ditunjukkan oleh stek dengan panjang 15 cm yang ditanam di media campuran tanah dan pupuk kandang kambing. Media terbaik untuk memicu inisiasi tunas muda Sansevieria adalah media campuran tanah dan pupuk kandang kambing. Panjang stek Sansevieria terbaik untuk perakaran adalah 10 dan 15 cm, sedangkan panjang stek terbaik untuk inisiasi tunas muda Sansevieria adalah panjang stek 15 cm. Stek Sansevieria dengan panjang 15 cm yang ditanam pada media campuran tanah dan pupuk kandang kambing merupakan perlakuan terbaik untuk inisiasi tunas muda Sansevieria.
