Judul: Studi Keanekaragaman dan Penyebaran Spasial Palem-Paleman (Arecaceae) di Hutan Lindung Gunung Slamet, Baturaden – Provinsi Jawa Tengah
Abstrak: Palm is one of interesting plant. It has been used for several needs and also a trading commodity. One of palms habitat is in Protected Forest of Mount Slamet. The threat of land conversion and forest fires is a problem in this area. The lack of information on the diversity, abundance and the distribution of palms make this area vulnerable and increated the possibility of unknown palms to go extinct. The purpose of the research is to describe the composition, diversity and the ecological distribution of palms and also analyzing the distribution of palms based on land and altitude. Research was conducted on May until June 2012, on two type of ecosystems natural forest and mix forest at Protected Forests of Mount Slamet. Data were collected using vegetation analysis method. Data of the palms were analyzed to obtain value of diversity, evenness and abundance of species. Spatial distribution Data were obtained from recording palms position. Thematic map of land and altitude was developed on processing the landsat map and divided them to different classes. Then, it was overlayed with palms point of occurence to produce a map of palms distribution based on land and altitude. Composition of palms on Protected Forests of Mount Slamet, on natural forest ecosystem found 12 species, and on mix forest ecosystem found 6 species. Distribution pattern of palms is clumped. The higest diversity of palms occurs on natural forest at 1.200 mdpl-1.300 mdpl with elevation 8-15 %, and mix forest at 900-1.000 mdpl with elevation 8-15%.

Judul: Keanekaragaman hayati jenis palem non rotan di areal kerja HPH PT. Intimpura Timber, Co. Kabupaten Sorong - Propinsi Irian Jaya
Abstrak: Palmae (Palem) merupakan salah satu dari tiga famili tumbuhan yang penting bagi kehidupan manusia dan dengan jumlah jenis yang banyak selain Leguminosae dan Graminae (Harlow, 1991). Irian Jaya sebagai salah satu pulau besar di Indonesia dengan luas hutan sekitar 92% dari luas daratannya, sudah pasti menyimpan sumberdaya tumbuhan yang sangat banyak jumlahnya tidak terkecuali Palem. Palem sangat menarik untuk dipelajari karena bukan hanya karena keindahan bentuk dan kegunaannya yang beraneka ragam. Peranan Palem dimasa datang akan semakin penting selaras dengan penganekaragaman berbagai sumber bahan untuk memenuhi kebutuhan manusia. Sementara itu dari waktu ke waktu erosi plasma nutfah yang terjadi, akibat dari pemanfaatan hutan akan membawa pengaruh dengan kekhawatiran jenis-jenis alami akan hilang. Tujuan Penelitian ini adalah untuk mengetahui jenis-jenis Palem non Rotan yang terdapat di areal HPH PT. Intimpura Timber Co. Sorong Irian Jaya, serta membuat kunci determinasinya dan mengetahui komposisi vegetasi hutan di areal HPH tersebut. Penelitian dilakukan di wilayah kerja HPH PT. Intimpura Timber Co. Sorong dengan lokasi contoh di Kawasan Pelestarian Plasma Nutfah (KPPN) dan di Areal Bekas Tebangan (ABT) I tahun dan dilakukan selama 2 bulan. Metode penelitian yang dilakukan berupa (1) Eksplorasi Jenis Palem. (2) Analisis Vegetasi, (3) Pembuatan Koleksi Herbarium, (4) Pertelaan Jenis. (5) Pembuatan Kunci Determinasi. Eksplorasi Jenis Palem dilakukan untuk mencari keanekaragaman hayati dan mengamati bentuk morfologi dari jenis Palem yang terdapat di areal tersebut. kemudian mengambil contoh herbarium serta dibuat foto vegetasinya.

Judul: Isolasi dan purifikasi inhibitor RNA helikase virus hepatitis C dari bakteriosin bakteri asam laktat S34
Abstrak: Target molecular therapy is one of method to prevent hepatitis C virus which was developed recently. NS3 Helicase/RNA helicase hepatitis C virus inhibition using inhibitory peptide are target in molecular therapy. Bacteriocin are inhibitory peptides which can inhibit hepatitis C virus through inhibition of NS3 helicase. Bacteriocin is a peptide which is produced by lactic acid bacteria. The aim of this research were to isolate and to purify bacteriocin from S34 lactic acid bacteria which has high activity to inhibit RNA helicase of hepatitis C virus. S34 lactic acid bacteria were identified using 16S RNA amplification and DNA sequencing identification of S34 lactic acid bacteria was Lactobacillus plantarum WCFS1. The bacterial growth reached logaritmic phase at 7 hours and stationary phase at 10 hours. Bacteriocin were isolated and purified by ammonium sulphate precipitation with 80% saturation, gel filtration chromatography, and characterization of bacteriocin through molecular weight analysis and measured protein concentration. Bacteriocin from S34 lactic acid bacteria were included in 2nd class bacteriocin, had 64.20 % of inhibition against RNA helicase hepatitis C virus, had molecular weight about 1.7-4.2 kDa, and specific activity in the amount of 2.84 x 106 U/mg.
