Judul: Pemetaan Provinsi di Indonesia Berdasarkan Peubah-Peubah Pendidikan
Abstrak: This paper provides a general overview about education in Indonesia and mapping of the provinces. The analysis is based on some educational variables, i.e. rough participation rate, pure participation rate, school participation, illiteracy rate, repetition rate, drop-outs rate and the average school duration. Provincial mapping is conducted by biplot analysis, which gives the following results. Based on the proximity among province and the interrelationship of province with educational variables, the provinces can be grouped into seven groups for elementary school, six groups for junior high school, and six groups for senior high school. The province of Papua has the highest illiteracy rate at all education levels being considered, i.e. elementary, junior, as well as senior high schools. On the other hand, the provinces of West Sumatra and West Papua have relatively high repetition rate. Moreover, the provinces of Jambi and Central Sulawesi have average values on all variables. This provincial mapping is expected to provide input in identifying the advantages and disadvantages of each province in order to improve the quality of national educational.

Judul: The Classification of Indonesia's Provinces based on Educational Indicators
Abstrak: Keberhasilan usaha pemerintah di bidang pendidikan dapat dievaluasi melalui indikator pendidikan. Ada 18 indilator pendidikan yang memberikan gambaran umum tentang kemampuan komunikasi penduduk, fasilitas pendidikan, dan tingkat partisipasi pendidikan dasar sampai Perguruan Tinggi. Secara nasional, penduduk usia sekolah telah menikmati pendidikan dasar, penduduk yang melek huruf dan mampu berbahasa Indonesia di atas 85%. Pada jenjang pendidikan menengah ternyata fasilitas dan tingkat partisipasi pendidikan belum mendukung peningkatan kualitas sumberdaya manusia dalam memasuki abad ke dua puluh satu. Dengan metode hirarki Pautan Rataan dan 18 indikator pendidikan ternyata dua puluh tujuh propinsi di Indonesia terpilah menjadi 9 Kelompok. Propinsi DKI Jakarta (gerombol IX) adalah propinsi dengan tingkat keberhasilan pembangunan pendidikan yang terbaik dibandingkan dengan keadaannya secara nasional kemudian diikuti oleh propinsi Sulawesi Utara (gerombol V). Sebaliknya, propinsi yang sangat perlu mendapat perhatian dalam pembangunan pendidikan adalah Timor Timur (gerombol VIII), kemudian NTT, NTB, Kalimantan Barat, Sulawesi Selatan, dan Irian Jaya (gerombol II), dan juga Jawa Tengah dan Jawa Timur (gerombol IV), serta Lampung (gerombol VII). Propinsi Yogyakarta dan Bali (gerombol VI) adalah propinsi-propinsi yang keberhasilan pembangunan pendidikannya sedikit di bawah rata-rata nasional sedangkan propinsi-propinsi yang lain (gerombol I dan II) tingkat keberhasilan pendidikannya sama dengan rata-rata nasional, hanya pada jenjang pendidikan menengah lebih rendah dari rata-rata nasional.

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
