Abstract

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.

Abstract

The level of reliability of a distribution system is very important to ensure the continuity of electricity supply to consumers. This research was conducted to calculate the Saidi reliability index and the Saifi 20 kV distribution system in Pinang PLN in 2017 with the help of the Matlab R2008a application. A GUI is one of the Matlab programs that is widely used in describing information and commands, and its users are possible to form and format themselves according to the needs of the system itself. With the help of this software, it is hoped that it will be easier to calculate the system reliability index, namely the calculation of SAIDI and SAIFI, then the results can be made so that the database is more organized. The calculation results obtained will show the highest and lowest SAIDI and SAIFI values ​​that occur in each of the current months, making it easier to evaluate, analyze and improve the reliability of the electrical power system network in the future, especially in PT.

Abstract

Electrical Measurement is one of the courses in Electrical Engineering, which consists of theoretical and practical subjects. The system of taking practical courses should be implemented after taking theoretical courses or simultaneously in one semester. But in reality there are still students who take practical courses before taking theoretical courses, especially in the Electrical Measurement course. Based on the description above, the researcher would describe whether there is an influence of learning outcomes of Electrical Measurement Theoretical Courses on learning outcomes of Electrical Measurement Practical Courses. This research must be held to measure motivation to learn of students and learn the interaction between learning motivation and Electrical Measurement Practical Courses. This research was analyzed using two-way ANAVA (Two Way ANOVAI) with a 2x2 factorial design and further tests using Tukey Test. The result was there is an interaction between Electrical Measurement Theoretical Courses and student's learning motivation of their Electrical Measurement Practical Courses' results. This can be seen from 16.66 and Ft = 4.04 at α = 0.05 with Fh> Ft means H1 is accepted.

Abstract

This goals as a shape of assessment of laboratory-primarily based totally realistic getting to know for guides completed withinside the Power System Analysis laboratory. This form of studies is a application assessment studies with a descriptive quantitative studies approach. The approach in accumulating studies statistics is with the aid of using the usage of a questionnaire given to academics and college students who take the AST direction practicum according with the Context, Input, Process & Product (CIPP) version assessment instrument, similarly to the questionnaire statistics series is completed with the aid of using commentary throughout the practicum. In this have a look at there had been eleven instructors and 15 college students who had been used as samples. From the sample, it indicates that the cost acquired with the aid of using the practicum lecturer in phrases of contextual is 84.090%, in phrases of enter is 90.150%, in phrases of technique is 89.770% and in phrases of product is 87.12%. From the scholar aspect, the effects finished primarily based totally at the expertise of realistic getting to know withinside the laboratory in phrases of contextual are 80.00%, in phrases of enter 83.660%, in phrases of technique 85.830% and 79.160% in phrases of product. Based at the effects of calculations from the aspect of the lecturer and college students that digital laboratory-primarily based totally realistic getting to know goes properly in order that college students` expertise is withinside the properly category.
