Inspection Data

The Atacama Desert receives the highest levels of solar irradiance in the world with an annual average of 2500 kWh/m2 for the global horizontal irradiance and 3500 kWh/m2 for the direct normal irradiance. One of the challenges is the large portion of ultraviolet light. This part of the spectrum be detrimental for the encapsulant materials, reducing their lifetime. To develop a module adapted to the Atacama Desert conditions, it is imperative to have standardized information from first-hand about the typical faults experienced by photovoltaic modules operating in the desert. This work reports on the design and implementation of the Inspection Data Collection Tool to evaluate crystalline silicon-based moules operating in desert climates. The tool brings together novel features of compatibility with current standards, efficient mobile-type instrumentation (equipment and tools), clear procedures/protocols for non-expert users and low development costs. A total of 95 modules were inspected to characterize failure/degradation issues. Three components of the solar modules were assessed: front cover glass, ethylene-vinyl acetate encapsulant and solar cells. Seven abnormalities were analyzed: Soiling, front cover glass discoloration, encapsulant delamination, hotspots, partial shading, cell fracture and faulty soldering. Soiling was the most common issue, showing correlation between dust deposition and location.

Research Questions

Tujuan dari penelitian ini yaitu untuk mengetahui proses bimbingan keagamaan, fungsi bimbingan keagamaan serta hasil bimbingan keagamaan dalam meningkatkan kecerdasan spiritual remaja di Boarding School SMK PPN Tanjungsari. Dengan pertanyaan penelitian 1) Bagaimana proses bimbingan keagamaan di Boarding School SMK PPN Tanjungsari?, 2) Bagaiamana fungsi bimbingan keagamaan di Boarding School SMK PPN Tanjungsari?, 3) Bagaimana hasil bimbingan keagamaan dalam meningkatkan kecerdasan spiritual remaja di Boarding School SMK PPN Tanjungsari?. Metode yang digunakan dalam penelitian ini adalah metode deskriptif kualitatif dengan teknik pengumpulan datanya dilakukan observasi, wawancara dan dokumentasi, dikarenakan masalah yang diteliti perlu dilukiskan secara sistematis dan faktual dengan menggambarkan keadaan atau status fenomena. Hasil bimbingan keagamaan di Boarding School SMK PPN adalah munculnya aspek-aspek kecerdasan spiritual pada remaja seperti kesadaran untuk menghayati proses ibadah bukan sebagai pengguguran kewajiban, terbiasa berperilaku baik, memiliki prinsip keadilan, memiliki prinsip kebenaran, mampu mengambil hikmah dari musibah yang dihadapinya, bersikap fleksibel, bersikap kritis dan merenungkan penyebab serta alasan segala sesuatu terjadi. Sehingga dapat disimpulkan bahwa bimbingan keagamaan di Boarding Schoool SMK PPN memiliki peranan yang sangat menunjang dalam meningkatkan kecerdasan spiritual remaja. The purpose of this study is to find out how the proccess of islamic guidance, function of islamic guidance, and result of islamic guidance to increase SpritualQuetiont in adolescence. With research questions 1) How the proccess of islamic guidance to increase spiritual quetiont on adolescence ?, 2) What is the function of islamic guidance to increase Spiritual Quetiont on adolescence?, 3) How are the results of islamic guidance to increase Spiritual Quetiont on adolescence?. The method used in this research is qualitative descriptive approach with subject and object of research is guidancer. While the data collection tool in this study through observation, direct interview and written interviews. From the results of research conducted at Boarding School SMK PPN Tanjungsari, it appears of Spiritual Quetiont in adolescents. Such as the behavior of living the worship process, get used to behave well, be fair, be wise, able to take lessons from the difficulties they experienced, be flexible, be critical.

The purpose of this research was to determine the effectiveness of the instruction process using the flipped classroom (FC) model within the scope of Computer Networks and Communication course. Theoretically, the community of inquiry model was taken as a reference and the effectiveness of the instruction process was evaluated accordingly. Students were preservice teachers studying Computer Education and Information Technology in the third grade in the Van region in Turkey. There were a total of 19 students, of which 12 are male and seven are female. FC process was carried out in the spring semester of 2018–2019 and lasted 11 weeks in total. A mixed-method design was used to gathering the data. Therefore, the research design was an explanatory design from mixed-methods designs. The quantitative data collection tool was the Turkish version of the Community of Inquiry Survey. The quantitative data were analyzed by dividing the students into very low, low, high, and very high levels. The qualitative data collection tool was the interview form created concerning the community of inquiry model. The qualitative data were analyzed by the use of the community of inquiry coding template's themes. At the end of the instruction process, students had a very high level of cognitive, social, and teaching presence perception. This situation was detailed and supported with the qualitative data obtained. Concerning the cognitive presence, the students firstly talked about that they started the learning process with videos. Regarding the social presence, they mentioned the motivating effect of the questions. About the teaching presence, participants firstly mentioned the direct instruction role of the videos.
