Judul: An Affective Instruction for Mathematics Teaching based on Hybrid Kansei Engineering Approach
Abstrak: One of the factors that influence the effectiveness of mathematics teaching is the design of mathematics course based on student's learning style. Based on their sensory preferences, students tend to have one or more of the three learning styles: visual, auditory, and kinesthetic. A traditional way to study and group students’ learning style is by asking students to fill in a questionnaire which may contain more than 100 questions. However, such an approach often leads to students’ boredom. To address this problem, we offer a new approach to group learning style by using opinion mining. Based on its motivation, the main objective of this research is to construct a mathematics teaching using Hybrid Kansei Engineering Approach. In particular, this research is focused on achieving the following objectives (1) To identify and group student’s learning style, (2) To verify and validate a mathematics teaching design. In this study, we consider 162 student opinions on mathematics teaching from three inclusive junior high schools in Bogor by spreading a one-page questionnaire. To study the opinions that can later be used to group the learning style and construct a mathematics teaching design, we have integrated three methods, namely Term Frequency-Inverse Document Frequency (TF-IDF), Semantic Differential (SD), and Principal Component Analysis (PCA). First, TFIDF is used to determine how important the words or opinions is to the collection. Then, SD Scales are used to evaluate student preferences. To extract the opinions as well as to cluster the learning styles, we use PCA approach, and Quantification Theory Type 1 (QT1) used to synthesize the relationship between teaching design and student preferences. The result of this study shows that 34% or 55 students had a visual learning style. Meanwhile, 12% or 20 students had an auditory style, and 54% or 87 students had a kinesthetic style. The results of this research indicate that the proposed approach can effectively group the student's learning style in mathematics teaching. Furthermore, it can potentially be recommended for teachers to design an effective mathematics teaching course. From these models, design support information was generated to assist teachers in developing the effective mathematics teaching. The result presented that all design specification of mathematics teaching was specific for each learning style and most of the rules were productive as the new design rules.

Judul: The Development of Mathematics Online Lesson Plan based on Computer Assisted Instructional
Abstrak: Lesson plan is a plan that describes procedures and organization of learning, in order to achieve a basic competency standards set out in content, and described in syllabus. Lesson plan of mathematics is one object of many learning materials applied in schools. System development lesson plan in mathematics is necessary to maximally support the needs of teachers and realization of a dynamic learning environment. The purpose of this research is to develop a prototype system of online mathematics lesson plan based on computer assisted instructional. The benefit of having such lesson plan is that it can ease teacher performance as a tool in manufacturing lesson plan effectively. Research method applied to develop system prototype was structural approach. The developed system offered several features which are teacher competency tests, lesson plans, tutorials, and a discussion forum for users. Prototype of the system has been tested offline, where all designed functions on navigation menu could run well. The developed system presents more optimal and effective lesson plans because it supports the use of teacher’s tacit and explicit knowledge, variations and flexibilities in creating lesson plans, and adjustable attributes. Furthermore, the system is also able to supply information on teaching feasibility and provides a variable lesson plan reports.

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
