Abstract

Writing in English is important for vocational high school (SMK) students toprepare their future career so that they can compete with other job seekers bothin Indonesia and other countries. However, the students find that writing isdifficult to learn due to some cases: (1) they are less interested in it because it isnot correlated with their major, (2) the limited time availability (3) the teachinglearning process is less meaningful, and (4) they are lack of feedback due to thebig number of students in one class. To overcome this problem, it is advisableto apply what so called integrated project based learning (PBL) by integratingwriting to recount the project dealing with the students’ major. This paperdescribes how the integrated PBL can enhance the students’ writing skill throughtwo main stages: (1) preparation stage. It is embodying grouping, determiningthe project work, determining the schedule, and learning the content as wellas how to write a recount text in the classroom. (2) individual writing activitywhich covers (a) free writing; (b) drafting; (c) evaluating (peer reviewing andteacher learner conference); (d) revising; (e) post writing; (f) publishing in asocial media; and (g) responding the social media reader’s comment.

Abstract

Atherosclerosis is a leading cause of cardiovascular disease-related death worldwide. Some studies suggested that the natural ingredients in coffee may negatively affect cardiovascular diseases, while other studies indicated that coffee contains anti-inflammatory compounds that are beneficial for cardiovascular diseases. The aim of this study was to measure the expression of P-selectin in aortic endothelial cells and the level of serum apolipoprotein A-1 (ApoA-1) in an atherosclerosis rat model after the administration of arabica and robusta coffee bean extracts at mild-moderate and high doses. An experimental study was conducted with a complete randomized design using 36 adult male white rats (Rattus norvegicus) divided into six groups: negative control (NC), positive control (PC), arabica mild-moderate dose (A1), arabica high dose (A2), robusta mild-moderate dose (R1), and robusta high dose (R2). Animals were induced atherosclerosis with atherogenic feed and then were treated with arabica and robusta coffee bean extracts at two different doses for four weeks. The results showed that the expression of P-selectin in the group of rats treated with robusta coffee bean extract was lower than arabica coffee bean extract group. Rats with robusta coffee bean extract mild-moderate dose had the highest ApoA-1 levels compared to other groups significantly (p<0.05). The level of ApoA-1 was higher in both mild-moderate and high dose of robusta coffee groups compared to the negative control group (both with p<0.001). In conclusion, mild-moderate intake of robusta coffee bean extract could reduce aortic P-selectin immunoexpression and increase serum ApoA-1 levels in an atherosclerosis rat model.

Abstract

The research location is located in Tanggetada sub-district, Kolaka district, which is an area very close to laterite nickel mining sites. The determination of the research location was deliberately chosen at the nickel mining location, with the consideration that at that location the river was brownish red, and at that location there were many miners who did not carry out according to mining regulations. The method used is observational which is carried out at nickel laterite mining sites. by using a cross sectional approach that is both qualitative and quantitative. Based on the results of the data analysis that has been carried out, it can be explained that the distribution of heavy metal pollution in river water is the largest in the heavy metal Copper (Cu), namely 0.0108 mg/l, which is found at station 3, heavy metal lead (Pb), namely 0.0070 mg/l l found at station 4, heavy metal chromium (Cr) is 0.0038 found at station 6 downstream, heavy metal Cadmium (Cd) is 0.0028 mg/l found at station 3, heavy metal Hexavalent Chromium (Cr6+) is 0.0026 mg/l found at station 2. From the results of the analysis there are no heavy metals that exceed the quality standard (PP No. 82 of 2001). Meanwhile, the river sediment material produced the greatest amount of heavy metal Copper (Cu), namely 0.0229 mg/kg found at station 2, Heavy metal Cadmium (Cd), namely 0.0128 mg/kg found at station 5, Heavy metal Lead (Pb) namely 0.0177 mg /kg is found at station 1 upstream, heavy metal Chromium (Cr) is 0.0118 mg/kg found at station 6 downstream, heavy metal Hexavalent Chromium (Cr6+) is 0.0116 mg/kg found at station 6 downstream. From the results of this analysis there are no heavy metals that exceed the quality standards (USEPA, 2003).
