MODEL DISTRIBUSI BAHAN AJAR UNIVERSITAS TERBUKA DAN IMPLEMENTASINYA
Get PDFUniversitas Terbuka (UT) was implementing the centralized distribution of learning material, it is not considered efficient. Therefore, the decentralized distribution system which requires 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 regional 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 systems, 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

HIV PREVALENCE AND SOCIO-ECONOMIC STATUS IN SUB-SAHARAN AFRICA
Get PDFDalam perkembangannya, HIV/AIDS bukan hanya menjadi masalah kesehatan, tetapi juga menjadi masalah sosial dan ekonomi. Kenyataannya, lebih dari 90 persen kasus HIV/AIDS ditemukan di Negara Sedang Berkembang (NSB), utamanya di Negara-negara Sub-Sahara Afrika. Hal ini menimbulkan pemikiran umum bahwa ada hubungan yang sangat erat antara HIV/AIDS dengan masalah-masalah sosial ekonomi seperti kemiskinan dan tingkat pendidikan. Dalam beberapa literatur dikemukakan bahwa pada banyak kasus di Afrika, terdapat hubungan positif antara HIV/ AIDS dan tingkat pendapatan dan tingkat pendidikan. Ini berarti bahwa, semakin tinggi taraf hidup masayarakat Afrika, semakin rentan pula mereka terhadap infeksi HIV/AIDS. Hal ini tentu bertentangan dengan pandangan yang umum di terima. Hal sebaliknya terjadi pada kasus Negara-negara Asia. Argumen yang masuk akal adalah, HIV/AIDS terjadi di Afrika ketika banyak orang belum mengetahui penyebab dan cara penyebarannya, padahal HIV/AIDS sangat berhubungan dengan gaya hidup dan mobilitas masyarakat. Masyarakat kelas menegah di Afrika adalah masyarakat yang lebih mobile dari kelompok lainnya, mereka umumnya tinggal di perkotaan atau di daerah perbatasan dengan Negara lain (sebagian besar Negara Afika tidak memiliki perbatasan laut/ landlock), sehingga resiko untuk terinfeksi menjadi lebih tinggi. Tidak seperti beberapa literatur yang membahas masalah HIV/AIDS di Afrika dengan kasus Negara per Negara, artikel ini mencoba mendekati permasalahan dengan analisis yang lebih makro, mencakup semua Negara Sub-Sahara, semua kelompok umur, dan lintas gender. Hasilnya adalah tidak adanya hubungan yang jelas antara banyaknya kasus HIV dan pendapatan per kapita. Sedangkan, pada kasus tingkat pendidikan, terdapat hubungan yang positif tetapi hubungan tersebut tidak linier

KINERJA BADAN PERWAKILAN LOKAL PADA ERA REFORMASI
Get PDFAs local parliament, Dewan Perwakilan Rakyat Daerah (DPRD) has three functions such as legislation, budgeting, and oversight functions. The research aims to analyse the local parliaments performance at Bogor and Depok city in the reform era. The reseach uses qualitative method. The data gathering technique used is snowball technique with depth-intervieuw and literature study of documents, books, journals, magazines, and daily newspapers that relate to the research issue. The study concludes that DPRDs performance in the reform era does not meet the public expectation yet. From the point of view of legislation and budgeting funcions, it tends to orientate itself to executives interest rather than publics. While from the view of oversight function, it has not used questionnaire and interpellation rights. The form of relation between DPRD and mayors of two cities contributes to the DPRDs performance as a whole. In order to increase the performance of the members of local parliament, it is necessary to increase their ability to identify their regions condition and needs. And it also needs to increase the quality of legislation, budgeting and oversight functions
