Judul: Pembuatan Model Ontologi untuk Student Profiling Berdasarkan Faktor Personal, Interpersonal, dan Lingkungan
Abstrak: Pada jenjang SMA dan perguruan tinggi, siswa diharuskan untuk memilih penjurusan sesuai dengan minat dan bakat siswa. Proses pemilihan ini seringkali membuat siswa merasa kebingungan dalam menentukan pilihan. Berdasarkan hasil penelitian Career Center Network, pada tahun 2017 sebanyak 87% mahasiswa Indonesia salah jurusan.

Student profile adalah sekumpulan informasi yang menggambarkan kebutuhan, keinginan, ketertarikan, serta perilaku seorang siswa. Dalam membuat profil tujuan yang luas, profil dapat dibuat dengan memenuhi tujuan tersebut dengan konsep ontologi. Konsep ontologi dapat digunakan untuk menyajikan profil siswa yang dapat dibaca oleh manusia dan dapat dipahami oleh komputer untuk diproses menjadi sistem lanjutan seperti rekomendasi. Penelitian ini bertujuan untuk merancang sebuah model ontologi sebagai dasar pembentukan profil siswa dengan mempertimbangkan aspek personal, lingkungan, dan interpersonal. Penelitian berhasil membuat ontologi siswa berdasarkan faktor-faktor penentu jurusan dengan 67 kelas dan 126 properti objek sebagai penghubung antar kelas yang sudah diuji dapat menyimpan pengetahuan yang dapat diakses dan ditambah kembali.

Judul: Model Regresi Logistik Biner untuk Identifikasi Faktor-Faktor yang Mempengaruhi Siswa Masuk Jurusan IPA/IPS
Abstrak: One direction is desired for students and parents is the science classes. On the one hand, this course allows the student has a choice of majors in universities more than other majors and a lot of work to only accept students from science classes. Ironically, many students who choose to major in science but does not support the student's ability. Dealing with the issue, it must be examined factors that influence students major in science. One method used to analyze the factors that affect students entering the science classes of binary logistic regression. Response variables used in this study categorical form of data on the status of the incoming students are students majoring in science or social studies. The data used in this study is population data class XI of SMAN 2 Bogor, West Java, the academic year 2012/2013. The number of total population is 279 students. Results of analysis of this study is binary logistic regression models produce values overall classification accuracy of 92.8% for the model classification table and 92.7% for the ROC curve. Explanatory variables used in this study a total of 18 explanatory variables and the explanatory variables are eight ties associated with variable responses to the real level of 5%. Wald test results obtained by the three explanatory variables that significantly influence the status of the students choose a major motivation, student aspirations and students are happy with the lesson or not exact.

Judul: The Effect Cassava Leaves Meal in The Diets on Body Weigbt, Percentage of Digestive Tract and Viscera of Mule Duck.
Abstrak: The mule ducks are the crossbreed between common duck females (Anas plathyrhynchos) and muscovy ducks (Cairino moschata) to improve the meat production in order to meet the animal protein requirement of the people. One of the problems in husbandry farming is highly feed cost. This problem can be solved with using highly available local sources and cheapness. Cassava leaves (Manihot esculenta Crantz) is the one local sources which can be used as an alternative feed, because it contains a rather high protein (24.1%) aud vitamin A (10,000-13,000 IU). A highly Hydrocyanide (HCN) as well as crude fiber in the cassava leaves are the limiting factors to be used as poultry diet. The ducks have more ability in digest the crude fiber than chicken. So that, using some cassava leaves in the diet does not make any problem.
