PLN Tertiary Education of Engineering is one of universities that focused on energy and electricity. The type of courses offered in Electrical Engineering major are theoretical courses and practical courses. One of the courses that consist both theoretical and practical courses is Electrical Measurement (EM). PLN Tertiary Education of Engineering suggested that students should apply for theoretical course before starting any practical course, or to take both courses in the same semester. However, there are still students who applied for practical courses before finishing theoretical course. Is there any correlation between theoretical and practical courses, as well as connection between Learning Motivation and Practical Course?. This research is conducted using Two-Way Analysis of Variance (two-way ANOVA) with factorial design of 2x2, and further testing using Tukey’s Range Test using the data of 2018 students’ results who are applying for practical courses with prior theoretical course participation and those without any prior theoretical course participation. Step 1: Data collection; Step 2: Requirement analysis test (normality and homogeneity); Step 3: Validity and Reliability test using learning motivation questionnaires; Step 4: Two-way ANOVA; Step 5: Tukey’s Range Test. Interaction found between EM course and student’s learning motivation towards the result of their EM practical work. This is evident from Fh = 16,66 and Ft = 4,04 at α = 0,05 with Fh > Ft which means H1 is accepted. Therefore, there is an impact between theoretical courses towards practical courses.

Metoda proyeksi peramalan energi umumnya masih berbentuk makro sehingga tidak memperlihatkan pusat-pusat beban pada wilayah yang lebih kecil (grid) dan mengakibatkan lokasi gardu distribusi tidak dapat ditentukan dengan pasti. Oleh karena itu diperlukan teknik prakiraan energi yang berbasis pada wilayah yang lebih kecil (mikrospasial). Prakiraan energi listrik yang melibatkan banyak variabel, hasil proyeksinya lebih akurat. Hal itu disebabkan proyeksinya melibatkan interaksi antar variabel dalam bentuk faktor. Setiap area pelayanan memiliki faktor dominan yang berbeda. Untuk menentukan faktor yang paling dominan dapat menggunakan Metoda Exploratory Factor Analysis. Metoda ini mampu menentukan variabel yang dominan diantara variabel-variabel yang terlibat. Dalam penelitian ini yang semula melibatkan 12 variabel independen, ada 4 variabel yang dapat dikelompokan menjadi satu faktor utama berdasarkan hasill Componen Transformation Matriks. Faktor tersebut akan digunakan dalam pemodelan matematis proyeksi kebutuhan energi. Sehingga hasil peramalan energi lebih teliti. Sejumlah metode analisis dengan statistika mengasumsikan distribusi datanya normal, sehingga asumsi ini perlu diuji kebenarannya. Beberapa uji normalitas yaitu dengan melihat penyebaran data pada sumber diagonal pada grafik Normal P-P Plot of regression standarized residual atau dengan uji One Sample Kolmogorov-Smirnov.
