Judul: Deskripsi Penggunaan Internet Di Kalangan  Mahasiswa Institut Pertanian Bogor
Abstrak: Today, internet has become important needs to all people, especially student. The aim of this research is to identify factors affecting student become an active or lapsed users of internet using binary logistic regression. This research also investigate factors affecting internet usage intensity of active users (devided into high, moderate, and low users) using ordinal logistic regression. By knowing these factors, the internet provider could determine the type of consumer they are going to reach. The object of this research is undergraduate students of Bogor Agriculture University that came in between year 2001-2004. Stratified sampling methods were used in this research using faculty as strata. Number of sample that was collected is 250 samples. Data shows that 81.6% are active users among them, 6.9%, 49.8%, and 43.3 % are high, moderate, and low users, respectively. The research show that the main factors affecting student become an active users of internet are (1) the use of internet for educational reason; (2) the use internet for personal communication, games, and access public information purposes; and (3) campus and internet cafe as location when using internet.

Judul: Penggunaan internet oleh mahasiswa studi kasus:mahasiswa FMIPA IPB angkatan 38-41
Abstrak: Di beberapa negara telah banyak dilakukan penelitian mengenai penggunaan Internet dengan menggunakan pendekatan kuantitatif. Dalam penelitian ini digunakan pendekatan kualitatif dengan pertimbangan bahwa penggunaan Internet berhubungan dengan perilaku manusia yang memiliki sifat terikat dengan keadaan sekitarnya dan relatif sulit untuk direduksi menjadi variabel-variabel fisik yang terukur. Mahasiswa merupakan kelompok masyarakat yang memiliki peluang untuk menggunakan Internet yang besar karena ketersediaan fasilitas Internet yang cenderung memusat di lingkungan pendidikan. Penelitian ini bertujuan untuk mendapatkan gambaran umum yang mendalam mengenai penggunaan Internet oleh mahasiswa FMIPA IPB yang mencakup alasan penggunaan, pemanfaatan fasilitas/ aplikasi yang disediakan Internet dengan menggunakan pendekatan kualitatif. Pengambilan data dilakukan dengan wawancara secara mendalam terhadap sebelas mahasiswa FMIPA IPB yang berasal dari 8 program studi serta dari 4 tingkatan yang berbeda. Subjek penelitian dipilih dengan menggunakan convinience sampling. Selanjutnya, analisis data dilakukan dengan menggunakan metode pembandingan konstan atau pengkodean kategori secara induktif dan simultan

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.
