Abstrak: Arrangement of plants is important in a golf course landscape which it add beauty, functions for comfort. The purpose of this research was to know the trend of green system in each landscape units of KGBR golf course that indicated by plant diversity and arrangement of plants. The research was also aimed to draw up recommendation on the green system of golf course. Diversity of plants on KGBR golf course were observed including value of frequency, value of abundance, dominance of species, and diversity index of plant. The function and aesthetic aspects of the plants was also analyzed by comparing the existing condition with ideal criteria obtained from study of literatures. Results of studies indicated that the plant with highest value of dominance, frequency, and abundance in most of golf course was Bermuda grass (Cynodon dactylon var. ’tifway’). The trend of green system in KGBR was designed with the concept of arboretum or collection of trees species ,which can be seen from the plants selection was mostly the type of trees. The diversity index of trees and shrubs in most of study area was classified in medium diversity. Meanwhile, groundcover plants in most of study area was classified in low diversity. Study area with highest diversity index of tree species (2,98) was found in area of 10th hole. The functional aspect in most of area studies is good and very good. The trend of plants arrangement in tee box and fairway in KGBR can grouped into three types, such as: line planting type, group planting type, and combination both line and group planting type. The plant arrangement in green areas was classified into two types, such as arrangement that only used tree formation with line type and arrangement that used the combination of trees, shrubs, and groundcover plants with line and group types.

Judul: Kajian Trend Tata Hijau pada Lanskap Area Permainan Lapangan Golf di Kabupaten Bogor
Abstrak: Melepaskan penat sangat dibutuhkan agar pikiran dapat beristirahat dari aktivitas yang dilakukan setiap hari. Beragam jenis olah raga yang dapat dilakukan dalam melepaskan penat salah satunya adalah golf. Olah raga ini juga menonjolkan lanskap alam sekitar sehingga pemain dapat berolah raga sambil berekreasi. Permainan golf ini dilakukan pada area terbuka dan pemain dapat menikmati keindahan alam sekitar permainan. Estetika lanskap dan fungsi dalam penataan ruang terbuka hijau pada lapangan golf memberikan nilai plus bagi olah raga golf sehingga menarik minat pemain dalam berolah raga. Keberadaan tanaman dalam suatu lanskap akan menghasilkan suatu trend tata hijau tersendiri dalam pemilihan jenis tanaman dan penataan tanaman. Gunung Geulis Golf & Country Club, Padang Golf Bukit Pelangi, dan Sentul Highlands Golf Club merupakan tiga lapangan golf yang terkenal di daerah Bogor. Penataan dan penggunaan tanaman pada tiga lapangan golf memunculkan trend tersendiri yang menjadi ciri khas dari lapangan golf. Tujuan dari penelitian ini adalah untuk mengetahui trend tata hijau yang terdapat pada lanskap lapangan golf di wilayah kabupaten Bogor dari segi penataan tanaman yang digunakan untuk estetika dan fungsi penanaman pada area permainan golf tersebut serta menyusun konsep tata hijau pada ketiga lanskap lapangan golf sebagai rekomendasi bagi para pengelola di ketiga lapangan golf. Hasil akhir penelitian ini dibatasi pada produk rekomendasi tata hijau dalam bentuk planting plan. Area studi yang diamati adalah bagian-bagian dari lanskap lapangan golf, yaitu tee box, rough, hazard, green, dan fairway. Keragaman jenis pohon, semak/perdu, groundcover dan rumput pada sebagian besar area studi pada tiga lokasi tergolong rendah. Lapangan golf Gunung geulis memiliki keragaman jenis pohon yang tergolong sedang dengan nilai 1,26. Jenis pohon dengan kelimpahan tertinggi pada lapangan golf Gunung Geulis adalah kelapa (Cocos nucifera), kelimpahan tertinggi pada lapangan golf Rainbow Hills adalah pinus (Pinus merkusii) dan kupu-kupu (Bauhinia purpurea), dan kelimpahan tertinggi pada lapangan golf Sentul Highlands adalah pinus (Pinus merkusii). Fungsi tanaman yang dibutuhkan pada ketiga lapangan golf adalah pembatas visual (screen), penahan erosi, pembatas hole permainan (border), dan peneduh. Secara keseluruhan, pemenuhan fungsi tanaman pada ketiga lokasi tergolong baik. Nilai aspek estetika pada sebagian besar area studi tergolong sedang.

Judul: Pemurnian dan karakterisasi protein inhibitor RNA helikase virus hepatitis C
Abstrak: Hepatitis C virus (HCV) infection is the second most common chronic viral infection in the world with global prevalence. This infection is contribution to chronic hepatitis and liver cirrhosis, often leading to hepatocellular carcinoma. There is no effective drug and vaccine available against HCV. The current standard treatment, a combination of pegylated interferon-α with ribavirin, is limited by its suboptimal response rate in a significant patient population, side effects, and affordability. Therefore, development of effective drug is needed. One approach to find out the candidate of antiviral drug is to discover the inhibitor of enzyme that essential for virus replication, such as RNA helicase. Streptomyces chartreusis 5-095 produce the inhibitor of HCV RNA helicase. The aim of this study was to purify the protein inhibitor which has inhibition activity against ATPase activity of RNA helicase HCV from S. chartreusis 5-095. The supernatant of culture S. chartreusis 5-095 exhibited high inhibiton activity against ATPase activity of RNA helicase HCV (approximately 72%) at 10 days of incubation. The extracellular protein inhibitor was partially purified by procedures of precipitation with ammonium sulfate to 65% saturation and gel filtration (Sephadex G50) using methanol water solution (4:6) as an eluen. The purity of protein inhibitor was monitored by SDS PAGE. The protein inhibitor showed a relative molecular mass were estimated to be 14 kDa and increased the purity 23,08 fold than those of the crude protein. The specific activity and IC50 after purification were 13,1338 U/mg and 0,0767 mg/mL, respectively. The activity of purified protein inhibitor showed its stability over pH range from 5-8 and optimum at pH 7,4. The inhibition activity showed its stability up to 70% at temperature 100 oC. The purified protein inhibitor relatively stable its activity at storage in the range of -20 oC to room temperature for 35 days.
