IDENTIFIKASI POTENSI GEOSITE DI WILAYAH KECAMATAN SEKOTONG MENUJU PERWUJUDAN GEOWISATA BERBASIS MASYARAKAT

Geowisata merupakan media yang sangat penting untuk dipahami oleh masyarakat sekitar lokasi karena suatu konsep manajemen pengembangan kawasan secara berkelanjutan. Untuk pengembangan geowisata yang berkelanjutan ini diperlukan tiga keragaman alam, yaitu keragaman geologi, keragaman hayati, dan keragaman budaya. Ini bertujuan untuk pembangunan serta pengembangan ekonomi kerakyatan yang berbasis pada asas perlindungan (konservasi) terhadap ketiga keragaman tersebut. Lokasi geowisata terletak pada wilayah Kecamatan Sekotong yang mempunyai lokasi situs-situs geologi pada tiap daerah, penelitian ini bertujuan untuk melakukan identifikasi terhadap potensi geo sites di Kecamatan Sekotong yang berpotensi untuk dikembangkan menjadi edu-geo tourism. Parameter yang digunakan dalam penelitian ini adalah nilai keilmuan dan intrinsik, nilai edukasi, nilai ekonomi, nilai konservasi, dan nilai tambah yang dimiliki oleh suatu geosite. Penelitian ini dilakukan dengan 3 metode, yaitu tahap studi pustaka, tahap penelitian lapangan, dan tahap analisis geosite dan geomorphosite dengan metode kuantitatif. Berdasarkan hasil penelitian di wilayah Kecamatan Sekotong terdapat suatu litologi daerah penelitian yang dikelompokan menjadi empat yaitu : Formasi Pengulung (TOMP). Formasi TMI (batuan terobosan). Formasi Kawangan (TOMK). dan Formasi Ekas. Berdasarkan pendekatan geosite dan geomorphosite menggunakan penilaian menurut Kubalikova (2013) dapat disimpulkan bahwa lokasi geosite yang berada di wilayah pantai memiliki nilai kelayakan lebih tinggi dibandingkan dengan yang berada di wilayah non pantai dengan nilai kelayakan antara 44,32% – 76,6% untuk dapat dijadikan edu-geo tourism

Egg yolk fatty acid profile of avian species - influence on human nutrition

Lipids are an important nutritional component of the avian egg. A review of the literature was completed to determine the fatty acid compositions in egg yolk from some avian species. Additionally, the nutritional influence of lipid and lipoprotein content on the plasma of male participants during 30-day feeding was discussed. The ostrich eggs had the highest unsaturated fatty acid and the lowest cholesterol content in relation to other avian species. Ostrich had a higher proportion of 18:3n-3 (p < 0.01) compared with other species. Chicken yolk numerically contained much higher levels of 22:6n-3 than those found in turkeys, quails and geese, but the amount of 22:6n-3 in ostrich egg was lower by comparison with other species (p < 0.01). After the storage of eggs at the room temperature, there was a notable loss of vitamin E (vitE) in the yolks of all species and this decrease was marginal (p < 0.01) in ostrich compared with other species. There were significant (p < 0.05) increases in plasma low-density lipoprotein (LDL) level in all male subjects. Plasma high-density lipoprotein (HDL) level decreased (p < 0.05) only in men who were fed chicken or ostrich eggs daily. Consumption of different species’ eggs had no influence on the total male plasma cholesterol and triglyceride levels. LDL-C:HDL-C ratio increased (p < 0.05) after goose and turkey egg consumption. Consumption of one egg/month by healthy human subjects had no effect on serum total cholesterol and triglyceride. The LDL-C:HDL-C ratio (which is a strong predictor of coronary heart disease risk) increased, although non-significantly, by consuming chicken, quail and ostrich eggs.http://onlinelibrary.wiley.com/journal/10.1111/(ISSN)1439-0396hb201

Effect of Angles of Harmonic Components of Back to Back Converter of Distributed Generation Resources on Current Behavior of Distribution Networks

The total current and voltage wave changes in the harmonic distribution networks is one of the major problems in distribution networks. By increasing the power electronic devices in the structure of electrical equipment such as laptop and mobile chargers, LED lights, etc., today, different components of the harmonics in the network can be seen. One of the major factors affecting the study of harmonic disturbances is the phase difference of harmonic components with the current angle in the main frequency. This can cause the phenomenon of peak and valley in waveform. Although, the presence of peaks or valleys in the waveform does not increase the effective amount of waveform, but the peaks result in the sharper waveform and increase the peak of domain. The peaks of waveform cannot be seen in the main equations, but practically can pass through electrical equipment including transformers, protective switches, relays, cables, and so on. The amount of peak points is sometimes from the nominal value of the above equipment current and will result in inappropriate performance and decreased lifetime. In this paper, using the Matlab software capabilities, the size and angle of the harmonic components of back to back converter, and extraction diode bridge rectifier AC-DC-AC, and effect of angles of each one to cause peaks and valleys in waveform will be analyzed and examined. The results of the study show that the converters used in the structure of distributed generation resources cause changes in angle of main component of current. The results also show that changes in the angles of diode bridge rectifier AC-DC-AC converter increased the peak of waveform by 26% compared to the main component of current, while in the back to back converter, there is a 9% deviation compared to the current in main component. The other simulation studies show that the angle change of 180 degrees reduces the waveform peak by 40%

Frequency of ischemic heart disease within metabolic syndrome

Background: The common clustering of glucose intolerance, abdominal adiposity, high triglyceride level, low high­density lipoprotein cholesterol level and high blood pressure in a single individual is referred to as Metabolic Syndrome (MS) and it is associated with ischaemic heart disease (IHD). Objectives: To find out the relationship between MS and lHD. Design: Cross sectional observational study. Materials: 100 subjects were selected following simple random sampling technique. 50 patients of MS and another 50 non MS were enrolled as case and controlled respectively in the department of medicine and cardiology at Sylhet M.A. G. Osmani medical college hospital. Results: Proportion of IHD was found to be high among the MS (40%) compared to non MS (16%) and the difference was statistically significant (p=0.008) indicating there is a relationship between MS and lliD. Among the components of MS proportion of hyperten­sion (39.2%), diabetes mellitus (41.9%), dyslipidernia (42.6%) and family history of cardiovascular disease (47.1 %) had significant higher association with patients with IHD (p<0.05). Conclusion: The MS has a significant association with IHD by electrocardiogram criteria
