Abstract

Nilai resistansi jenis tanah dipengaruhi beberapa faktor yaitu jenis tanah (liat,berpasir dan berbatuan), lapisan tanah, kelembaban tanah, temperatur. Penggunaan NGR (Neutral Grounding Resistor) sebagai tahanan titik netral sekunder trafo merupakan bagian dari koordinasi proteksi dalam sistem kelistrikan karena tanpa pentanahan yang baik dapat membahayakan makhluk hidup yang ada di sekitar trafo bahkan dapat merusak trafo tersebut. Tujuan penelitian ini adalah untuk mengetahui nilai tahanan pentanahan serta pengaruhnya terhadap sistem pentanahan NGR 40 ohm dan efektifitasnya terhadap proteksi feeder. Metode penelitian kuantitatif dengan melakukan pengukuran nilai tahanan pentanahan dan NGR yang dilanjutkan dengan melakukan simulasi menggunakan aplikasi program komputer ETAP 16.0. Data-data sistem diperoleh dari PT. PLN Pekat dan direpresentasikan kedalam SLD pada ETAP 16.0. Hasil perhitungan diperoleh arus gangguan satu fasa ke tanah tergantung nilai tahanan sistem pentanahan dan lokasi gangguan. Dari pengukuran bahwa besar nilai sistem pentanahan di sistem kelistrikan Pekat sebesar 157.8 ohm. Simulasi gangguan pada feeder dengan nilai sistem pentanahan sebesar 40 ohm diperoleh arus maksimal gangguan satu fasa ke tanah sebesar 269 Ampere, sedangkan pada sistem pentanahan 157.8 ohm diperoleh arus maksimal gangguan satu fasa ke tanah sebesar 75 Ampere.

Abstract

The Journalistic Code of Ethics plays a very important role in the world of the press as a guide to the values of the journalistic profession, so that the journalistic code of ethics must be understood and implemented by journalists. This research is motivated by problems in implementing the photojournalism code of ethics. The aim of this research is to find out how the photojournalism code of ethics is applied to accident news on Tribunjambi.com. The research approach that researchers use is a qualitative approach with content analysis. Qualitative research is research used to examine the condition of natural objects where the researcher is the core instrument. The types of data used in this research are primary data and secondary data with data collection through documentation, observation and interviews. Apart from that, data analysis techniques use data reduction, data presentation and data verification and are continued by checking the validity of the data. The results of this research can be concluded that the application of the code of ethics for photojournalism in general is still not in accordance with press law. Likewise with the journalistic code of ethics which regulates the work of journalists and media in broadcasting photos in news stories. Like other online media, the Tribunjambi.com website will of course try to implement the photojournalism code of ethics every day, but when implementing the photojournalism code of ethics, it is certainly not as easy as desired and expected. Factors that support Tribunjambi.com in implementing a journalistic code of ethics are the provision that Tribunjambi.com provides to its journalists before creating and broadcasting a story, looking for journalists who already have an understanding of the journalistic code of ethics, and providing advice and infrastructure that journalists need. and staff, while the inhibiting factor that journalists, editors in chief and publishers may face in implementing the code of ethics for photojournalism is that they forget or do not pay attention that photos containing sadistic elements should be blurred Keywords: Analysis, Code of Ethics, Photojournalism, Accident

Abstract

This research aimed to determine the significant correlation between learning interests and students' learning achievement at MTs Al Mafaz. The research design is a quantitative analysis. The researchers used purposive sampling. The samples comprised 15 students in grade seven, and the data were obtained from the questionnaire and documentation. The technique used to analyze the data is simple correlation with SPSS 21 v.21 Program. The result of the research showed that the value of the Coefficient Correlation 0,01 means that there is no correlation between parents' attention and learning achievement, it was a very weak correlation based on the table interpretation of correlation, and it is based on the value significance Sig. (2-tailed) The correlation between learning interest and students' learning achievement is 0,957 > 0,05. There is no significant correlation between learning interest and students' learning achievement. The hypothesis is Null Hypothesis (Ho) is accepted, and Hypothesis Alternative (Ha) is rejected.

Abstract

The purpose of this study is to identify the factors influencing the students' difficulties in achieving high intermediate score on the toefl itp of English Department at Madako University.The participants in this study are eight semester English students who have taken the TOEFL test and the researcher only took 8 student out of 28 over all. This study use an interview as the instrument in collecting the data and descriptive qualitative is the method of this research .Analyze and interpret the data through qualitative procedures by doing an interview, if the answer questioned after the analysis feel unsatisfactory, the researcher will ask question again until a certain point in time there is data that is considered credible. After all the data is collected, then data reduction is carried out after sorting and selecting the data essentials are completed, then the data is presented in the form of descriptive text and then conclusions are made. The finding of this study are the lack of consistent and comprehensive practice, along with low intrinsic motivation, serves as significant barriers, as many students only start practicing close to the exam and do so merely to fulfill administrative requirements. Additionally, limitations in basic English skills, particularly in grammar and listening, also affect their performance and causing the student difficult to accomplish a high intermediate score
