Abstract

Transformator daya adalah bagian integral dari hampir semua jaringan penyaluran daya listrik mulai dari pembangkitan sampai ke pengguna energi listrik (jaringan transmisi dan distribusi). Pelayanan yang baik merupakan hal yang sangat penting dalam suplai daya listrik. Ada sejumlah faktor yang menggganggu operasi sebuah transformator, diantaranya adalah keberadaan harmonisa listrik dalam sistem tenaga listrik. Perkembangan penggunaan beban-beban listrik non linear yang sejalan dengan perkembangan pengunaan komponen dan peralatan berbasiskan pada konverter daya. Tulisan ini memberikan kajian pengaruh harmonisa terhadap unjuk kerja dari sebuah transformator dengan adanya harmonisa yang dikhususkan atas adanya DC bias.Analisis dilakukan lewat Simulasi menggunakan software MATLAB dan verifikasi dilakukan lewat data eksperimental. Hasil menujukkan keluaran simulasi bersesuain dengan data pengujian langsung. DC bias mengakibatkan pola harmonisa orde genap juga menjadi lebih signifikan.

Abstract

Lau borus is an outlet located on Lau Kawar Lake. The location of lau borus is located at the foot of mount sinabung where this mountain has experienced quite high eruptive activity for several years. Determination of the status of water quality in these waters using the Pollution Index Method following the Regulation of the Minister of the Environment number 115 of 2003 and the Regulation of the Minister of Health Number 32 of 2017. The parameters that will be tested in this study are TDS, pH, Fe, SO4, COD, BOD, Cu, Cl, Pb, NH3, Total Coliform. The study was conducted at 3 sample points taken by purposive sampling. The average results of the calculation of the Lau Borus Waters Pollution Index method Outlet Lau Kawar Lightly Polluted Lake (scores from 1.86 to 2.19). While the results of Permenkes number 32 of 2017 the total coliform results show that this value has exceeded the average value. These results indicate that the quality status is influenced by pollutants from Iron (Fe) and Total Coliform which are above the quality standard. The relationship between the eruption activity of Mount Sinabung and the quality of Lau Borus during sampling did not cause a significant pollution impact from volcanic ash pollutants. The cause of Lau Borus pollution is from the wind direction. The percentage results from the eruption wind direction towards Lake Lau Kawar. the direction of the lake with the opposite direction is 1: 8. The eruption towards the Lau Borus Outlet, Lake Lau Kawar, is relatively small compared to the opposite direction.

Abstract

The rapid global spread of COVID-19 requires practical prevention efforts, including vaccination. Public knowledge plays a crucial role in preventing transmission, and one factor influencing knowledge is education level. This study examines the relationship between educational attainment and COVID-19 vaccination status in Medan Tuntungan District. Using a cross-sectional design, the research involved 100 respondents from 68,000 individuals aged 18 and above. Data were collected through questionnaires and analyzed using univariate and bivariate methods. The results show no significant correlation between education level and COVID-19 vaccination status (p-value = 0.096). Several factors contribute to this, including widespread access to information through mass media and public campaigns and knowledge gained outside formal education. In conclusion, education level does not impact the COVID-19 vaccination status of the community in Medan Tuntungan District. The implication of these findings is the importance of a broader and more equitable communication strategy in vaccination campaigns, focusing on groups with high levels of education and covering groups with lower levels of education through easily accessible media.
