Abstract

Makalah ini memaparkan hasil pengembangan model evaluasi pembelajaran dari serangkaian dimensi penilaian portofolio, proyek, presentasi proyek dan tes tulis. Penelitian dilaksanakan pada kegiatan praktikum teknik analog melalui model pembelajaran project based learning (PjBL). Logika fuzzy merupakan suatu alternatif alat pengambil keputusan yang dapat diaplikasikan untuk mengevaluasi hasil pembelajaran. Keputusan akhir dalam evaluasi PjBL menghasilkan proses evaluasi yang tidak kaku dan objektif karena keputusan akhir dapat ditentukan melalui proses defuzzifikasi yang sepenuhnya dilakukan menggunakan fuzzy logic toolbox.  Model evaluasi berbasis logika fuzzy diharapkan mendapat trend yang baik dan bisa menjadi petunjuk untuk mengembangkan model evaluasi yang diadopsi di sekolah.

Abstract

Tertiary learning institutions are under immense pressure to evolve within the realms of the fourth industrial revolution. The flipped classroom model externalizes in-class traditional learning and internalizes outside class activities in an attempt to move students from lower order cognitive skills to higher order cognitive skills. Training institutions are anticipated to minimize learning costs in the face of increasing enrollments. The broad aim of the study was to establish whether a flipped pedagogy would enhance performance and improve students’ perceptions over the conventional classroom pedagogy. To examine the impact of a flipped learning model, an experiment was conducted on two classes studying fundamentals of electrical engineering course. The participants were 64 pure electrical engineering students sampled from a population of 156 first year electrical engineering students. 32 students were assigned to the experimental group which was exposed to both the flipped classroom model and traditional classroom model. The remaining 32 were solely exposed to the traditional classroom pedagogy. Evaluation survey was administered on both the flipped and traditional cohort. Although students revealed positive perceptions of the flipped classroom model, empirically, there was no significant differences in academic achievements of students taught using either instructional approach. 83.87% of the flipped students were better off with a conflated instructional pedagogy as canvassed through the questionnaire survey. Educational practitioners ought to move up with the fourth industrial revolution demands by adopting a blended instructional approach.

Abstract

The purpose of this study was to demonstrate a new design of low-cost and portable laboratory kit that is prospective for supporting teaching and learning on the automation process. The kit consists of the water tank filling system (sizes of 50 mL; as a model for describing reallistic tank in the plant) equipped with a programmable logic controller (PLC) integrated with SCADA system, human machine interface (HMI) monitor, reservoir, temperature, water level sensors, mixer, and heater. To be adaptable in any types of classroom, the kit was placed on the portable table (length x width x height of 100 x 50 x 150 cm). To approach the industrial tank system in industry, the tank was designed to be mixed and connected to other tank, and the temperature and water volumetric (water level) was controllable. To examine the impact of the designed kit on the improvement of teaching and learning process, the problem based learning (PBL) approach was also conducted in class. The economic analysis result showed that the present kit is inexpensive and portable, compared to other commercially available kits/devices. The PBL results showed that the kit is simple and to give better illustrations for students to comprehend the process control system in the realistic application in industry. Further developments of this kit is potentially implemented as an experimental tool for undergraduate students.

Abstract

Makalah ini memaparkan hasil penelitian tentang prakiraan beban puncak jangka panjang berbasis kecerdasan buatan menggunakan algoritma ANFIS (Adaptive Neuro-Fuzzy Inference System). Data masukan yang digunakan adalah faktor-faktor utama yang mempengaruhi kenaikan beban listrik dari tahun 2000 sampai dengan tahun 2008. Hasil prakiraan beban puncak pada akhir tahun 2025 dengan aplikasi ANFIS  (Adaptive Neuro-Fuzzy Inference System) tidak berbeda jauh dengan prakiraan dalam Rencana Umum Ketenagalistrikan Nasional (RUKN), yaitu masing-masing sebesar 79.134MW dan 79.920 MW, dengan kelajuan rata - rata sekitar 6,93%  setiap tahunnya.

Abstract

The effective development of a Mobile-Based Assessment (MBA) depends on students’ acceptance. The aim of this paper was to examine the determinant factor of students’ behavioral intention to use mobile-based assessment. Data were collected from 105 second grade students of a vocational high school through an online survey questionnaire. Partial Least Squares (PLS) was used to test the measurement and the structural model. Results showed Perceived Ease of Use as the strongest direct predictor of Behavioral Intention to Use, followed by Perceived Usefulness. Content and Mobile Self-Efficacy only has an indirect effect. These four variables explain 51.3 percent of the variance of Behavioral Intention to Use.

Abstract

The development of renewable energy has been constantly conducted as an attempt to increase energy diversification, improve energy sustainability and reduce greenhouse gas emissions, including the wind power plant (WPP). Suitable location selection is urgently necessary to achieve optimized output and high economic values. There are multi-criteria to be considered during the selection process, namely wind velocity, climate condition, road access, environmental impact, land use, land tilt, plain condition, distance to residential areas, etc. This study aimed to develop a software supporting multi-criteria decision-making based on artificial intelligent technology, namely fuzzy analytic hierarchy process (fuzzy-AHP) which was implemented to evaluate the WPP location suitability. The method of fuzzy-AHP is believed to be able to generate prioritized criteria supporting the location of WPP with high accuracy. Based on those criteria, there were two locations identified at Tanah Laut Regency, South Kalimantan, Indonesia, as the most suitable research sites. It is expected that studies employing fuzzy-AHP are to be further developed to determine wider renewable WPP locations.

Abstract

The availability of educational facilities is still a problem in many countries. Inadequate laboratory equipment will affect student learning outcomes and the quality of graduates. Therefore, many studies have developed low-cost laboratories as an alternative solution. This article aims to study the development of low-cost laboratories and their implementation in learning. This study used the systematic literature review (SLR) method. The articles used in this study were published from 2017–2021 and obtained from the IEEE Xplore database. After the papers were accepted, we were selected using inclusion and exclusion criteria. Thirty-two articles were used. The results show that a low-cost laboratory can be an alternative solution to the high price of commercial equipment and a learning tool to improve learning outcomes. The methods used in implementing low-cost laboratories are design, research and development, and experimentation. Using low-cost laboratories in learning activities improves the quality of learning outcomes.
