The oxidation of low-density lipoprotein (LDL) is believed to be the initiating factor for the development and progression of atherosclerosis.  Curcuminoid, the metabolite of Zingiberaceae family such as temu mangga (Curcuma mangga), has been shown to reduce the susceptibility of LDL to oxidation. In this study, we examined the effect of curcuminoid extracted from temu mangga on copper ion-induced lipid peroxidation of low density lipoprotein (LDL) in mice’s macrophages and Macaca nemestrina’s monocytes.  Analyses were done by measuring the formation of thiobarbituric acid reactive substance (TBARS) as malonaldehyde (MDA).  LDL were harvested and isolated from 5 adult female Macaca fascicularis  fed aterogenic diet for 3 months.  LDL oxidation by mice macrophage incubated for 4 hours were inhibited by curcuminoid at concentration of 8 ppm.  There was decreased 17% (P<0.01) in the concentration of MDA compared to control without curcuminoid (31.99B±0. vs 36.77A±0.9 nmol/mg protein LDL, respectively).  Inhibiton of LDL oxidation in M. nemestrina macrophage were highest by curcuminoid at 8 ppm for 4 hours and 6 hours incubation.  There was 14.8% and 23% inhibiton (P<0.01) (23.768 ± 0.095A vs 27.111B±0.972 and 23.37B±0.12 vs 30.87A±2.49 nmol/mg LDL protein, respectively).  These data suggest that curcuminoid of temu mangga were able to inhibit LDL oxidation in the cellular level, therefore offer protection against oxidation of LDL.

One of the important factors for the management activity at Salak Mountain is the presence of Salak Mountain’s vegetation classification, which until recently has never been done. The research objectives were to classify the variety of vegetation types at Salak Mountain. Vegetation sampling was made with systematic sampling with random start. Vegetation type at alliance level was determined with vegetation ordination. Three vegetation alliances can be extracted from the ordination. These alliances are Shcima walichii-Pandanus punctatus/ Cincora sinensis forest alliance; Glocidion apus-Mallotus blumeana/Chima sinensis forest alliance; and Pinus merkusii-Dysoxiylum arborescens/Dysoxiylum dichotoma forest alliance. Vegetation alliances are forming mainly because of their similarity in their structure, composition, and physiognomy of vegetation. The abiotic factors that consistently differentiate alliance 1 with the other alliances are N total, dust content of the soil, and slope. P soil’s content is the abiotic factor that consistently differentiates alliance 2 with the other alliances, while C organic soil’s content and cation exchange capacity of the soil are the abiotic factors that consistently differentiate alliance 3 with the other alliances. There are five vegetation association at allinace 1, six alliance 2 and seven at alliance 3. Each dominant spesies has uniquely preference to abiotic factor in their distribution at Gunung Salak. Stand structures of alliance 1 and 3 forming J reverse curve.
