"Penelitian ini merupakan pengembangan yang dilakukan untuk menghasilkan Buku Ajar Pendidikan Matematika II yang dapat digunakan sebagai salah satu sumber belajar bagi mahasiswa Pendidikan Guru Sekolah Dasar (PGSD) semester IV. Pengembangan yang digunakan mengacu pada model pengembangan ADDIE, yang terdiri atas 5 tahap, yaitu (1) analisis, (2) perancangan, (3) pengembangan, (4) implementasi, (5) evaluasi. Produk penelitian berupa Buku Ajar Pendidikan Matematika II menggunakan pendekatan Pendidikan Matematika Realistik. Prototipe produk divalidasi oleh ahli, ahli desain, ahli media, kemudian dilakukan uji perorangan dan uji kelompok. Data dikumpulkan dengan menggunakan kuesioner dan pedoman wawancara. Data yang didapatkan dianalisis dengan statistik deskriptif. Dari hasil kuesioner dan wawancara diketahui bahwa buku ajar yang dikembangkan layak diterapkan kepada mahasiswa PGSD. "

"Universitas Terbuka (UT) was implementing the centralized distribution of learning material, it is not considered effisient. Therefore, the decentralized distribution system which required warehouses at certain regional offices will be proposed. The aims of this research are (1) investigating the decentralized learning material distribution model, (2) choosing the optimal location of warehouses to minimize the cost of learning material distribution, (3) choosing the rgional offices which will be served optimally by each warehouse, (4) comparing efficiency of the centralized and decentralized learning material distribution system. The distribution problem is modeled as a linear mixed integer programming problem. The model will be solved using Branch and Bound method. This study considers centralized learning material distribution system and two alternative of decentralized learning material distribution system, which are alternative 1 and alternative 2. It is found that in 2008 the cost of the alternative 2 is lower than the centralized learning distribution system. Besides, if the demand of learning material is increasing, the alternative 2 is still less costly than the other systems."

"Gender issue becomes an interesting concern in education for there has been cultural bias and gender inequalities that unconsiously spread out though teaching and learning activities. Some learning materials, especially in elementary and secondary school, still show gender bias on occupation of women general."
