Salah satu faktor yang menyebabkan rendahnya hasil belajar siswa adalah penggunaan model pembelajaran terapan yang tidak optimal. Tujuan penelitian ini adalah untuk mengetahui perbedaan kemandirian dan hasil belajar Designing Network menggunakan model Project Based Learning dan modul digital seminar Think Pair Share padasiswakelas XI TKJ di SMKN 3 Malang. Metodepenelitianinimenggunakan Quasi Experiment dengan Post-Test Only Design. Instrumen yang digunakan adalah lembar observasi independensi dan ketermapilan, serta pertanyaan postest dalam bentuk pilihan ganda dengan jumlah 34 pertanyaan. Hasil penelitian menunjukkan bahwa ada perbedaan yang signifikan dalam kemandirian siswa dengan nilai signifikansi Sig. (2-tailed) = 0,003. Namun, tidak ada perbedaan yang signifikan dalam hasil belajar dari domain pengetahuan Sig. (2-tailed) = 0,577 dan Sig keterampilan siswa. (2-tailed) = 0,431.

CNN originates from image processing and is not commonly known as a forecasting technique in time-series analysis which depends on the quality of input data. One of the methods to improve the quality is by smoothing the data. This study introduces a novel hybrid exponential smoothing using CNN called Smoothed-CNN (S-CNN). The method of combining tactics outperforms the majority of individual solutions in forecasting. The S-CNN was compared with the original CNN method and other forecasting methods such as Multilayer Perceptron (MLP) and Long Short-Term Memory (LSTM). The dataset is a year time-series of daily website visitors. Since there are no special rules for using the number of hidden layers, the Lucas number was used. The results show that S-CNN is better than MLP and LSTM, with the best MSE of 0.012147693 using 76 hidden layers at 80%:20% data composition.
The main objective of this project is to investigate the performance conventional method of perturb and observe (P&O) and soft computing techniques (fuzzy logic and adaptive neuro-fuzzy inference system) of maximum power point tracking (MPPT) for photovoltaic (PV) module. In this paper, the MSX-64 PV module and boost DC-DC converter are used for simulation and modeling the MPPT system. This work demonstrates the performance of those three types of MPPT techniques, which subjected to a partial shading pattern as well as a non-shaded and shaded of real weather profile. These MPPT techniques are compare in terms of power extracted, MPPT efficiency, rise time, its ability to track global maximum power point (MPP), and the response to varied weather. Simulation results of soft computing MPPT techniques have shown the ability to track the MPP during partial shading conditions and the response to weather changes when nonshaded real weather profile applied to the system. The performance of the conventional P&O based MPPT has depicted the failure of this controller to track the global MPP during partial shading and lack response to real weather changes. The proposed system has simulated using MATLAB SIMULINK.
There is a paradigm shift in curriculum development and learning in 21-st century universities. The curriculum is no longer organized in a separate but in integrated manner or commonly referred to as transdisciplinary approach. Several transdisciplinary learning strategies need to be considered, to be studied and developed as learning innovations. One strategy initiated through this paper is the Personalized Online Training System (POTS). POTS provided opportunities for students to search, process, analyze, interpret, and communicate data and information obtained on POTS media. POTS developed based on Generation Z characteristics that are very familiar with technology, have a good self-confidence, high initiative, creative and innovative. The research instrument used questionnaire with a Likert scale using the UEQ framework to 118 students. The result showed that user experience score, usability score, learning design validation score, and students’ response from the interview session indicate that the system is good; yet an improvement is needed.
The research aimed to develop Android-based teaching material to improve the understanding of Software Engineering of Informatics Engineering students whose validity and effectiveness are measured. The method used in this paper is Research and Development (R&D) with the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) model which is used to develop An-droid-based teaching material. The validity of teaching material product has con-firmed by media experts and material experts in their fields. The effectiveness of the product was measured through the post-test only control group design with two groups of Informatics Engineering students in Higher Education involving 57 people. Data collection was carried out through questionnaires and tests, with descriptive analysis for the results of the validation of teaching material and pilot tests and t-tests for testing the effectiveness of teaching material. The results showed that Android-based teaching material is easy to use and has video tutorial features and quiz menus that provide direct feedback to users, so teaching materi-al can be applied as a valid and effective learning media in increasing student un-derstanding of Software Engineering material which has never been applied in the research location so far. Based on the results obtained, further research can be carried out on a broader subject and pay attention to other aspects such as increasing motivation and metacognitive students of Informatics Engineering.
<p>In this paper, a proposed design, fabrication and testing of sine wave oscillator “LC” type (Hartley and Colpitts oscillator) has been performed using five approaches. The first approach proposed design is done theoretically using the basic theorems used to generate oscillations, such as the condition of oscillation criteria and determine the values of capacitor (C) and inductor (L) component, Secondly it is done using simulation technique (LTSpice IV), Thirdly the simulated design is implemented practically using IC OP-AMP 741 with passive elements such as resistors, capacitors and inductors by oscilloscope and frequency generator. Fourthly design the Hartley and colpitts tool kit by 2-D and 3-D, layouting the circuit by Eagle PCB design software then package into tool box which integrated each other. Finaly, the LC-oscillator tool kit was tested such as resistor, capasitor and inductor module and write the result into tables (for jobsheet data).</p>
