Judul: Proses peroksidasi lipid kelinci yang hiperlipidemia pada pemberian senyawa penurun kolesterol
Abstrak: Radikal bebas banyak mendapat perhatian akhir-akhir ini karena dianggap memiliki peran yang cukup signifikan dalam terjadinya berbagai penyakit degeneratif. Hiperlipidemia adalah salah satu faktor resiko aterosklerosis yang mengarah pada penyakit degeneratif tersebut. Penelitian ini bertujuan mengukur konsentrasi lipid peroksida pada darah kelinci yang hiperlipidemia dan pengaruh senyawa penurun kolesterol terhadap konsentrasi lipid peroksidanya. Sebanyak 20 ekor kelinci jantan galur New Zealand white dibagi menjadi empat kelompok percobaan, yaitu kelompok normal yang hanya diberi pakan standar, hiperlipidemia yang diberi pakan aterogenik (kolesterol 0.5% dan minyak kelapa 5%), lovastatin yang diberi campuran pakan aterogenik dan lovastatin (57 mg/hari), dan ekstrak yang diberi campuran pakan aterogenik dan ekstrak ramuan daun jati belanda. Analisis lipid peroksida darah menggunakan metode tiobarbiturat (Yagi 1994) yang mengukur senyawa malonaldialdehida (MDA) menggunakan spektrofotometer pada λ = 532 nm. Hasil percobaan menunjukkan pemberian pakan aterogenik pada kelinci menyebabkan peningkatan konsentrasi MDA, yang berarti meningkatnya proses peroksidasi lipid dalam tubuh. Kelompok hiperlipidemia mengalami peningkatan konsentrasi lípid peroksida darah sebesar 163.76% bila dibandingkan kelompok normal (1.30 ± 0.38 nmol/ml). Lovastatin dan ekstrak ramuan daun jati belanda dapat berperan sebagai antioksidan dengan cara menurunkan konsentrasi lipid peroksida darah sebesar 46.92% dan 53.03% berturut-turut pada minggu ke-8 perlakuan dibandingkan kelompok hiperlipidemia.

Abstrak: Free radicals, such as lipid peroxide, are having much attention right now because their significant role in degenerative disease. Hyperlipidemia is one of the major risk factor for atherosclerosis and lead to degenerative disease. The aim of this study was to determine the effect of cholesterol lowering substance to the blood peroxide lipid concentration in hyperlipidemic rabbit. Twenty four male New Zealand white rabbits were divided into four groups: normal (given standard rabbit feed), hyperlipidemia (given atherogenic rabbit feed contained 0.5% cholesterol and 5% coconut oil), lovastatin (given mixture of atherogenic rabbit feed and lovastatin 57 mg/day), and extract (given atherogenic rabbit feed and jati belanda leaves extract mixture). Thiobarbitnric acid (TBA) method was used in blood lipid peroxide analysis, measuring the MDA product by spectrophotometer at 532 nm. The result showed that the atherogenic rabbit feed caused the elevation of MDA concentration, which means the elevation of lipid peroxidation process. Blood lipid peroxide concentration in hyperlipidemia group increased 163.76% compared with normal group (1.30 ± 0.38 nmol/ml). Lovastatin and jati belanda leaves extract mixture can act as antioxidant which can lowering blood lipid peroxide concentration 46.92% and 53.03% respectively at 8th week compared with hyperlipidemia group.

Abstrak: The presentation of information on tourism and public facilities in the city of Bogor to the community in general and in particular Bogor society becomes important. In that case we need a media that can provide information on all aspects related to tourism and public facilities in the city of Bogor. It would be better if the media allows the public to obtain the information needed quickly and easily for distribution. This study aims to build a Geographic Information System of Tourism and Public Facilities in the City of Bogor Portable using spatial database development, with a presentation that is easily accessible by all parties without restrictions of space and time. The information is presented in the form of maps and textual information on Tourism and Public Facilities in the City of Bogor. This system has a weakness during the process because the access time is longer than the system that run directly on the computer
