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: Analisis kebutuhan ruang terbuka hijau di Kota Pekanbaru
Abstrak: The main factor in environmental issues is human population. The increase of population is a major source that triggering the development of residential and other permanently public facilities. Therefore, the need of energy such as electricity, petroleum, gasoline and diesel fuel increase significantly. The existing urban green space due to the conversion of residential development is decreasing. Scattered clusters of inhabitant and residential site in one particular area generate a kind of negative impact into environmental carrying capacity. The need of energy as a sequencing consequence from urban development was considerably distressing the quality of air in Kota Pekanbaru. The study was purposed to estimate the need of urban green space based on total area, number of citizens and CO2 level. The standard for the need of urban green space is acquired by literatures study. The estimated total need of urban green space was obtained from land coverage analysis, whereas the level of CO2 was estimated from an amount of energy consumption (electricity, petroleum, gasoline and diesel fuel) and emission factors that obtained furthermore from literature. The result of this study revealed that based on the size of area, Kota Pekanbaru was experiencing a shortage of green space for 12.499,27 ha, but considerably insufficient condition based on population and CO2 emission, as well as Kecamatan Rumbai dan Kecamatan Bukit Raya for subsequent level. To comply a standard prerequirement in such space, Kecamatan Pekanbaru Kota was recommended to extend as large as 3.033,19 ha urban forest. For another district that were Kecamatan Senapelan, Limapuluh, Sukajadi Sail, Rumbai, Bukit Raya and Tampan required open spaces 266 ha, 164,62 ha, 246,34 ha, 130,40 ha, 5.305,67 ha, 2.206,76 ha, and 4.134,84 ha, respectively.

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.
