Judul: Pendugaan Nilai dan Distribusi Spasial Densitas Ikan dengan Sistem Akustik Bim Terbagi (Split Beam Accoustic System) di Laut: Arafura pada Bulan Oktober 2003
Abstrak: Orientasi pembangunan sektor kelautan dan perikanan di Indonesia saat ini mulai diarahkan pada wilayah Indonesia Timur. Laut Arafura merupakan salah satu perairan di wilayah Indonesia Timur yang saat ini banyak dieksploitasi sumber daya ikannya oleh nelayan dalam negeri maupun nelayan asing. informasi mengenai densitas ikan dan distribusinya sangatlah diperlukan untuk mengetahui potensi perikanan dan membantu menentukan,fishing ground bagi para nelayan. Oleh karena itu dilakukanlah penelitian tentang pendugaan nilai dan distribusi spasial densitas ikan dengan menggunakan metode akustik di Laut Arafura sebagai upaya untuk mendukung tersedianya informasi tersebut.

Judul: Aplikasi Metode Hidroakustik Dalam Penentuan Arah dan Kecepatan Renang Ikan di Perairan Laut Arafura pada Bulan Oktober - November 2003
Abstrak: Laut adalah ekosistem yang luas dengan berbagai jenis biota terkandung di dalamnya, salah satu sumberdaya hayati laut yaitu ikan. Sumberdaya ikan mempunyai potensi besar untuk dapat dimanfaatkan secara optimal dalam rangka meningkatkan kesejahteraan masyarakat Indonesia. Indonesia merupakan negara bahari dimana kira-kira dua pertiga wilayah Indonesia adalah perairan laut. Di perkirakan potensi sumberdaya ikan belum dimanfaatkan secara optimal dan belum diketahui dimana keberadaannya serta sebarannya secara nyata di perairan Indonesia.

Judul: Studi Pengaruh Variasi Pemberian Kadar EGCG (Epigallocatechin gallate) Teh Hijau Dalam Mengontrol Level Glukosa Plasma Darah Post-Prandial Pada Subjek Dewasa Muda Sehat
Abstrak: Green tea is widely consumed both in Asian and Western countries. Many beneficial effects of green tea are related to its catechin, particularly (-)- epigallocatechin-3-gallate (EGCG) content. The present study was aimed at providing evidence of improvement on glucose metabolism in healthy humans upon green tea beverage consumption in various levels of EGCG (0, 100, and 200 mg EGCG). This study showed that introducing of 100 and 200 mg EGCG reduced increased blood glucose level on healthy humans (p<0,05). Repeated ANOVA showed that treatments given were significantly affect blood glucose response for each minutes of observation (p=0.002). The ANOVA showed that treatments given were significantly affect AUC (area under curve) value (p=0.006) and glucose score (p=0.006). There were significant difference of AUC value (p=0.02) and glucose score (p=0.002) between 0 mg EGCG (control) and 100 mg EGCG group. Likewise, there were significant difference of AUC value (p=0.002) and glucose score (p=0.018) between 0 mg EGCG (control) and 200 mg EGCG group. Although AUC value and glucose score of 200 mg EGCG group were lower than 100 mg EGCG group, but there were no significant difference in between (p=0.287 and p=0.33, respectively). The clinical value on lowering blood glucose showed that subjects in 100 and 200 mg EGCG groups had relative risk value 0.4-0.7 and 0.3-0.7 compared to the control group respectively. When EGCG consumed by body, then the number of hyperglycaemia incidence could be reduced by 40-60% and 30-70% from the previous incidence respectively, while difference between numbers of hyperglycaemia incidence were 40-60% and 30-70% between subjects who received 100 and 200 mg EGCG compared to the control group respectively.
