Abstrak: Hypercholesterolemia and LDL oxidation are the major factors of atherosclerosis. The ethanol extract of the ginger (EEG) and Zn each posses effect reduce cholesterol and antioxidant. These research combined EEG and Zn as antihypercholesterolemia and antioxidant to prevent atheroma in New Zealand white fed rabbits atherogenic diet and hypercholesterolemia rabbits. Twenty eight male rabbits were divided into seven groups. For 6 weeks, group 1 was fed with a normal diet and group 3 was fed with an atherogenic diet. Beside the atherogenic diet, group 2,4,5,6, and 7 were also treated by supplementary treatment. Second phase research, 24 male hypercholesterolemia rabbits were divided into 6 groups. For 6 weeks, group 1 was fed with a normal diet. Fed rabbits atherogenic diet group 2,4,5,6, and 7 and hypercholesterolemia rabbits group 2,3,4,5, and 6 were treated by supplementary treatment, which are Zn 6.67 mg/kg, EEG 200 mg/kg, combination EEG 50 mg/kg and Zn 6.67 mg/kg, combination EEG 100 mg/kg and Zn 6.67 mg/kg, and atorvastatin (positive control) 1.9 mg/kb BW per day. Combination EEG 50 mg/kg and Zn 6.67 mg/kg and combination EEG 100 mg/kg and Zn 6.67 mg/kg treatment impeded the increase of total cholesterol, LDL, and prevent atheroma equal to the positive control. Based on the ability to restrain the increase of MDA (lipid peroxidation) in fed rabbits atherogenic diet the treatment with combination EEG 50 mg/kg and Zn 6.67 mg/kg resulted higher than positive control or the other treatment. Based on reduced plaque atheroma in hypercholesterolemia rabbits, combination EEG 50 mg/kg and Zn 6.67 mg/ kg treatment also the best result. These researches concluded that combination EEG 50 mg/kg and Zn 6.67 mg/kg BW per day treatment exhibited the highest atheroma prevention effect in fed rabbits atherogenic diet or hypercholesterolemia rabbits as compared to the positive control or the other treatments.

Judul: Proses Peroksidasi Lipid Kelinci yang Hiperlipidemia pada Pemberian Senyawa Penurun Kolesterol
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.

Judul: Studi kasus migran pedagang kaki lima di pasar Senen, Jakarta Pusat
Abstrak: Sejak Jakarta menjadi ibukota negara RI, Jakarta tidak pernah sepi dari arus migrasi penduduk. Masuknya para migran ke Jakarta disebabkan karena pertumbuhan fisik yang nyata, yaitu dari pembangunan gedung perkantoran, fasilitas hiburan dan lainnya, memberi daya tarik bagi orang bukan penduduk Jakarta.
