Judul: Analisa kebutuhan ruang parkir kendaraan pada pusat pertokoan kota Pekanbaru
Abstrak: Pesatnya pertumbuhan fisik kota-kota dalam beberapa dasawarsa terakhir telah memunculkan konsekuensi logis berupa meningkatnya permintaan terhadap ruang lahan untuk pembangunan pusat-pusat kegiatan bisnis, komersil, perdagangan, industri, perumahan dan lain-lain. Hingga batas tertentu pembangunan pusat kegiatan berskala besar seperti plaza, mal, supermarket, swalayan dan lain-lain telah memenuhi kebutuhan sarana ruang parkir untuk menghindari kemacetan lalu lintas yang dimungkinkan terjadi pada ruas jalan di sekitarnya.

Judul: Preferensi masyarakat terhadap ketersediaan taman kota di Kota Pekanbaru – Propinsi Riau
Abstrak: Urban park is one type of public open space in urban areas that people use to interact with the environment and other people. At present, many parks are available at urban area but rarely used or visited by the urban community because of those parks are not suitable to people preferences. This study aims to determine and analyze community preferences on the availability of urban park in Pekanbaru City. The method used in this study were qualitative and quantitative methods of analysis, which consist of content analysis and Multiple Correspondency Analysis (MCA). The study showed that the current system of urban park system in Pekanbaru City are the distribution pattern of the park where the park has not been evenly spread across the center of city, the availability of the park is still low (0.17 m2/jiwa of 0.3 m2/person it should be) and 93.8% of the whole park is a large garden (> 1500 m2), the shape and design of the park tend to be equal to the characteristic feel of Malays in the ornaments, the dominant function of the park that is a function of architecture as part of the aesthetic aspects of the city, and facilities predominantly recreational park (children playground, lawn, sports facilities (reflection track, volleyball court, basketball court and the tenant of the park is dominated by the city government's. Analysis of legal aspects related park system shown that the existing regulatory system already supports existing landscaping, but has not spelled out in technical detail and the lack of community participation in planning and formulation of regulations. Community preferences to park variables are park location close to settlements (<1,000 m), large park size (> 1500 m2), the function as a place of recreation and sports, and facilities within the park area. Recommendations resulting from this study that urban park availability based on community preference in Pekanbaru City are distribution within the city evently, short distance from home or center of daily activities, active type of recreation, quite large park size, organic design, save and comfort park. The recommendation of the availability model of a city park are expected to contribute to the Government of Pekanbaru City in determining the policies and actions in the management of urban parks in the future.

Judul: Peptides Hydrolysate Derived from Collagen of Snakehead Murrel (Channa striata) Skin Demonstrate Anti-oxidant and Anti-cholesterol Activities.
Abstrak: Anti-cholesterol and anti-oxidant play crucial role to combat cardiovascular disease (CVD) related to formation of arterial plagues from oxidation of cholesterol. In the past decades, research on bioactive peptides demonstrating anti-cholesterol and anti-oxidant activities have been reported as the alternative drugs. In this study, acid soluble collagen was extracted from the skin of snakehead murrel and employed to induce production of collagenase by Bacillus licheniformis F11.4. The collagenases secreted were in turn purified through AKTA Purifier (ion exchange, DEAE column) and used to produce peptides hydrolysate. The purified enzymes were grouped in two distinct collagenase fractions, designated as fraction D and F. Peptides hydrolysate produced by the fraction D was found to demonstrate HMG-CoA inhibitor activity comparable to pravastatin and limited anti-oxidant activity. Meanwhile, peptides hydrolysate generated using the fraction F demonstrated anti-oxidant activity comparable to BHT (2mM), vitamin C (2mM) and vitamin E (2mM), but limited HMG-CoA activity. Combination of the fraction D and F resulted in substantial HMG-CoA inhibition and anti-oxidant activities.
