The Effect of Alpha Lipoic Acid in Preventing Atherosclerosis Lesion on the Abdominal Aorta of Diabetes Mellitus Type 2 Rats

Various studies have studied the clinical use of alpha-lipoic acid (ALA) for treating diabetic complications. The protective effect of  lipoic acid in  atherosclerosis induced by diabetes mellitus type 2 (DM type 2)  still needs further study. This study was aimed to investigate the protective effect of ALA in atherosclerosis induced by DM type 2. Twenty one rats were divided into 3 groups: control, DM−treated and DM+ALA-treated group. Type-2 diabetes was induced by intraperitoneal injection of streptozotocin (50 mg/kg) followed by nicotinamide (110 mg/kg). ALA was administered orally at a dose of 60 mg/kg body weight/day throughout the feeding period for three weeks. This study was an experimental study with post-test only with control method which was conducted at Biochemistry laboratory, Faculty of Medicine Universitas Riau from June-October 2016. This study showed that DM+ALA treated group  achieved lower atherosclerosis scores than DM-treated group and the difference between the two groups was statistically significant. In conclusion, alpha lipoic acid can prevent atherosclerosis lesions induced by diabetes

Perbandingan Nilai Daya Dukung Tanah Dasar Badan Jalan Yang Distabilisasi Semen Dan Abu Sekam Padi

Strength and durability of road pavement depend on engineering properties of subgrade. However, soils used as subgrade may not satisfy the required quality. Expansive clayey soils can pose problems and cause pavement failure. A research about characteristic of soil stabilized with cement and rice husk ash was conducted to overcome these problems. This paper intends to compare bearing capacity of soft subgrade soil stabilized with cement and rice husk ash. The effectiveness of cement and rice husk ash in improving the engineering properties of soil can be directly compared since the sample of soil was collected from the same location and treated with the same treatment. By adding cement and rice husk ash, the bearing capacity of clayey soil increased significantly. For soil stabilized with cement, the soaked CBR was higher than that of the unsoaked. Opposite phenomenon occurred in soil stabilized with rice husk ash, as its bearing capacity reduced after soaking in the water. Therefore moisture change during design life of road pavement should be anticipated such as using appropriate drainage system

The Indonesian Islamic Bank\u27s Spin-off: a Study in Regional Development Banks

The Islamic banking spin-off became a major issue after the establishment of the Act No. 21 of 2008. The problem that arises according to this spin-off is the existence of sharia unit that owned by the regional development banks, which is almost the banks has a small size. This paper is going to evaluate the spin-off criteria are regional development banks, besides that this article is going to analyze the spin-off strategy that can use by sharia unit that owned by the regional development bank. The techniques that employed in this paper are ARIMA, simulation, and descriptive-qualitative. The result shows that there is no sharia unit can achieve the 50% share asset of its parents. There are also several strategies that can be used by the sharia unit. The main thing that should emphasize is the Islamic bank\u27s spin-off is only one of the policies that can be taken to develop the Islamic banking industryDOI: 10.15408/aiq.v9i1.430

Analisis Pengaruh Islamic Corporate Governance terhadap Corporate Social Responsibility (Studi Kasus pada Bank Syariah di Indonesia)

This study aims to examine the influence of Islamic corporate governance, size of the Board of Commissioners, the composition of the Board of Commissioners, Frequency of Meetings of the Board of Commissioners, the size of the Audit Committee Independent, The composition of the Audit Committee Number of Meetings Audit Committee, Profitability and Liquidity on the disclosure of corporate social responsibility (case study on the bank Sharia in Indonesia). This research is a quantitative study using scientific research in the form of positive economics. The nature and type of this research is descriptive method used is based on a survey of the literature. Data used is secondary data obtained from www.bi.go.id and corporate websites. The analytical method used is multiple linear regression analysis with SPSS version 22. The population in this study are all Islamic banks registered in Bank Indonesia during the period 2012 to 2014. While the sample is determined by using purposive sampling method in order to obtain a sample of 10 banks with observations for 3 years.Based on the results of multiple regression analysis with significance level of 5%, then the results of this study concluded: (1) Islamic Corporate Governance consisting of Existence and expertise Sharia Supervisory Board has no significant effect on the disclosure of corporate social responsibility. (2) The size of the BOC significant effect on the disclosure of corporate social responsibility. (3) The composition of the Board of Commissioners has no significant effect on the disclosure of corporate social responsibility. (4) The frequency of the number of board meetings no significant effect on the disclosure of disclosure of corporate social responsibility. (5) The size independent audit committee has no significant effect on the disclosure of corporate social responsibility. (6) The composition of the independent audit committee has no significant effect on the disclosure of corporate social responsibility. (7) The number of meetings of the audit committee has no significant effect on the disclosure of corporate social responsibility. (8) Profitability has no significant effect on the disclosure of corporate social responsibility. (9) Liquidity no significant effect on the disclosure of corporate social responsibility. (10) Islamic corporate governance, size of the Board of Commissioners, the composition of the Board of Commissioners, Frequency of Meetings of the Board of Commissioners, the size of the Audit Committee Independent, The composition of the Audit Committee Number of Meetings Audit Committee, Profitability and Liquidity on the disclosure of corporate social responsibility jointly significant effect on disclosures corporate social responsibility.DOI: 10.15408/ess.v5i1.233

Fourier Series Nonparametric Regression for the Modelizing of the Tidal

The method of statistic used to estimate the estimation of sea water level is by nonparametric regression approaching of Fourier series. The rob flood caused by sea level rise in Semarang becomes a dissolved problem until today This results the need of modeling to predict and know how high sea level is.The fourier series have fluctuative data pattern because of its periodic character. This makes Fourier series as the appropriate approaching to modelize the sea tidal. Before modelizing the sea tidal with Fourier series approaching, It is previously necessary to find the optimal K value . Based on the determination of optimal K value, with GCV method, It is obtanied K equals 277. The result of average data of the Semarang sea tidal with reggression nonparametic method showed that R 2 is 95% and MSE = 4,42. The lowest tidalestimation resulted in Semarang is on March 2, 2016. Then the highest tidal estimation in Semarang Cityoccurred on August 31, 2016
