LECTURERS’ FEEDBACK ON WHATSAPP GROUP: STUDENTS’ PERCEPTION DURING ONLINE CLASS
Get PDF  Abstract: This research is aimed to know the students’ responses to the feedback given by the lecturers during online class and to know the students’ motivation after feedback given. This research belongs to descriptive qualitative. Sampling technique used was purposive sampling. The participants were students of the second semester who takes an English major in Samarinda. The results showed that students felt happy with the feedback given by lecturers toward the learning materials. They can identify their mistakes, so they can correct them immediately and will not repeat the same mistakes. The students also appreciate it because it really helps them as students to be better in the future. In addition, the feedback given also can improve students’ motivation. They become more enthusiastic to learn more.Keywords: feedbacks, perception, online learnin
ANALYSIS OF COST OF SALES AND SALES ON NET INCOME
Get PDFThis study aims to analyze The cost of sales and sales of net income in retail trading companies listed on the Bursa Efek Indonesia. The population and sample in this study are the financial statements of 12 retail trading companies listed on the Bursa Efek Indonesia for the period 2016-2018. This research technique uses classic assumption test, multiple linear regression analysis, hypothesis test and determination coefficient test. The collection technique uses the documentation and literature review methods. And after the data was collected, the test analysis in this study was carried out with the help of IBM SPSS 26 for Windows. Based on the results of the F test that The cost of sales and sold together has a simultaneous effect on net income in 12 retail trading sub-sector trading companies listed on the Bursa Efek Indonesia
Keausan Poros Propeller yang Berlebihan Akibat Beban Radial Seal pada Lingkungan Air Laut
Get PDFGesekan antara dua benda secara terus menerus mengakibatkan timbulnya keausan. Keausan yang terus menerus terbentuk mengakibatkan adanya kerusakan dan kecacatan pada material yang terkikis. Faktor yang akan menimbulkan terjadinya keausan dalam pemilihan material sangat mungkin menjadi bahan masukan dalam merencanakan suatu sistem propulsi. Tujuan dari penelitian ini adalah untuk mengetahui perilaku karakteitik keausan pada pasangan material kontak antara poros dengan seal akibat beban radial pada lingkungan air laut. Metode numerik dengan pendekatan Reynold dilakukan untuk mendapatkan  pendekatan secara matematis terhadap pertemuan kontak antara dua benda. Terjadinya keausan seal dan poros propeller juga disebabkan oleh kombinasi antara interaksi gesekan terhadap pelumasan air laut. Beban radial pada putaran poros propeller menjadikan seal dan poros propeller mengalami keausan pada tingkat, volume, dan kedalaman yang berbeda-beda
Pengaruh Anoda Magnesium Alloy AZ91D Terhadap Pola Korosi Galvanis Pada Logam Yang Tecelup Air Laut
Get PDFAir laut atau garam merupakan elektrolit yang sangat agresif dan korosif bila terkena logam, yang menjelaskan bahwa korosi pada struktur laut / lepas pantai pada berbagai jenis logam dan paduan baja, berbicara sangat berbahaya, tidak hanya untuk struktur terendam, tetapi juga karena keadaan presentasi. Tujuan dari makalah ini adalah untuk menganalisis pengaruh anoda magnesium alloy AZ91D terhadap pola korosi galvanis pada logam yang terpapar air laut.Penelitian ini tentang penerapan struktur pengorbanan magnesium dan dapat diterapkan pada struktur bawah air yang terpapar air laut yang diperoleh dari penelitian sebelumnya. . Dalam hal ini kinerja kedua paduan akan dinilai dengan meliputi potensi proteksi dan arus galvanik yang dapat dihasilkan, kapasitas, efisiensi, tingkat konsumsi, waktu induksi, dan jalur korosi. Dengan demikian dapat dikatakan bahwa faktor dan desain lingkungan, seperti konsentrasi garam terlarut dan variasi luas yang didukung, juga telah diuji pengaruhnya terhadap kemampuan bahan paduan. Hasil penelitian ini menunjukkan bahwa material magnesium alloy AZ91D dapat diaplikasikan pada logam yang terpapar air laut seperti kapal dan struktur bawah laut, karena ketahanannya yang lebih tinggi terhadap korosi galvanik. Magnesium AZ91D juga memiliki ketahanan terhadap banyak waktu di laut. Sehingga upaya peningkatan ketahanan magnesium terhadap logam yang berhubungan dengan air laut seperti kapal dan struktur bawah laut, spesimen AZ91D akan lebih baik dengan logam aluminium untuk meningkatkan ketahanan korosi dan lebih sulit daripada tidak terika
THE RELATIONSHIP BETWEEN TEACHERS’ MOTIVATION AND STUDENTS’ ENGLISH COMMUNICATION SKILL
Get PDFMotivation plays an essential role in the teaching and learning process of students in class. Through motivation can be determined success or failure in the teaching and learning process. This study was conducted to determine the relationship of teacher motivation with students' English communication skills in Middle School of Malang Regency. Calculation of the correlation between motivation and English communication skills of students using Stastical Product and Service Solution V.23 (SPSS 23). In descriptive statistics with 30 respondents, the average motivation value was 44.67 with a standard deviation of 3.14. While the average value for English communication skills or student achievement is 30 people at 78.90 with a standard deviation of 3.99. The correlation between the two variables of motivation and achievement is 0.741. In sig. (2-tailed) of 0,000 in the sense that there is a significant correlation between students' motivation and English communication skills (achievement) because the correlation value is smaller than 0.05
DO YOU KNOW WHY INDONESIANS GO TO DOCTORAL STUDY?
No full textAbstract: The point of the examination is to discover answers to the topic of why some Indonesians choose to keep learning at the postgraduate level in the wake of finishing their master’s program. At the core of the examination is the investigation of the intentions or reasons which Indonesian, qualified people that could take up the other business then to become doctoral understudies. Motivation for accomplishing something is ordinarily alluded to as a lot of inside and outside variables that impact the choices or practices. In this venture, we did an overview of the thought processes to turn into a doctoral understudy through the recollections of PhD graduates. A subjective examination focused on the portrayal of 250 doctoral alumni who are presently functioning as teachers at Indonesian. Every one of them represented considerable authority in the field of instructive examinations and worked at a college for a limit of five years after the culmination of doctoral investigations. This exploration is a social examination which is remembered for non-trial research utilizing a logical worldview dependent on negative perspectives or quantitative ideal models. Keywords: Doctoral Study; Motivation and Educational Research
