“…Pembiasaan pada praktikum online berguna untuk membiasakan pengguna dengan aturan praktikum aslinya Simulasi praktikum online dapat menjadi solusi yang dapat menggantikan prkatikum offline, karena praktikum online ini berbasis simulasi yang memberikan pengalaman bagi pengguna untuk menggunakan alat dan bahan praktikum. Simulasi praktikum dapat meningkatkan minat belajar siswa, mengurangi kesalahan saat praktikum sebenarnya, dan memberikan pemahaman materi yang lebih dalam (Samijayani & Astharini, 2014).…”

The COVID-19 pandemic has caused the implementation of education in Indonesia to be carried out online. Some lessons that require practice, such as Biology, experience obstacles. The solution that has been carried out is by conducting independent experiments, but this cannot facilitate practicum on submicroscopic materials such as cells. The availibility of a virtual laboratory during a pandemic that is effective, efficient, and economical is urgently needed. The purpose of this study was to produce an interactive online microscope, test the validity of the media, and test the effectiveness of the media. The research was conducted at SMA Negeri 3 Malang in grade 11 D3. This online microscope was developed by Lee and Owens (2004) including Analyze, Design, Development, Implementation, Evaluation. The Analyze stage produced need assessment and front-end analyze data. The Design stage produced material and media designs. The Development stage produced an interactive online microscope with a material validation value of 93%, media validation 88%, and a practicality test of 96%. The Implementation phase was not carried out. In Evaluation stage, an evaluation is carried out for media evaluation. It can be concluded that this online microscope is practical and valid to meet the needs of online practicum

“…This trainer kit can be included in the curriculum of the study program or department in certain subjects where there are prerequisites as previously mentioned. It is also highly recommended that students perform a circuit simulation first (virtual lab method) before carrying out a real practicum (hands-on method) to minimize equipment damage [23]- [25] while providing an overview of the actual practicum. This accelerates students' understanding of previously abstract material.…”

“…This trainer kit has been developed with its own design and has helped solve the problem that is generally faced by electronics laboratories in developing countries such as Indonesia. This problem is primarily the limited use of learning media because the procurement of imported trainer kits tends to be expensive [39], and not necessarily in accordance with the expectations of lecturers and learning objectives that have been designed according to the existing curriculum [23], [40], [41]. The operation of this trainer kit is easy, where students only provide a trainer kit, resistor module, capacitor module, measuring instruments (Oscilloscope & Frequency Counter), and asymmetric power supply.…”

This research develops a phase-shift RC Oscillator trainer kit that can be used to give undergraduate students an understanding of one of the materials related to analog circuit practicum. The Oscillator is one of the essential subtopics to be examined thoroughly by electrical engineering students. Furthermore, the Resistor and Capacitor modules were provided separately to be connected to the trainer through jumper cables. The phase-shift RC circuit in the trainer kit used a single Op-Amp 741 while the Network model utilized an Inverting Amplifier to determine the gain which must be ≥ 29 times, therefore, Rfeedback ≥ 29 Rgain (Rfeedback = 30 kΩ and Rgain = 1 kΩ). Two tasks in this learning media were completed by students, namely measuring the output frequency and observing the phase shift. The output signal on this trainer kit was observed using only an Oscilloscope and a frequency counter. The phase inverter of the phase-shift RC Oscillator adjusts the output signal by 180o and sends feedback to the input, therefore, there is positive feedback. Meanwhile, the trainer kit had an output frequency specification of ~649 Hz (C = 100 nF, R = 1 kΩ) and it shifts the phase by 60o on each RC network. Using 2 and 3 R-C networks, the phase shifts were 120o and 180o, respectively. The trainer kit was packaged in a box made of acrylic with dimensions l x w x h = 20 cm x 28 cm x 5 mm. Through a questionnaire consisting of 13 criteria, this trainer kit was declared valid, namely r count > 0.2960 (5%) and reliable (Cronbach's alpha > 0.60, which was 0.732) to be used as a learning media based on user responses, namely students (N = 35). In the context of technical education, this trainer kit also supports the efficient implementation of practicum without compromising the learning objectives due to the ease of operation (plug & play through jumper cables) compared to fully assembling the circuit using a project board.

“…Pada penelitian ini akan dibuat sebuah sistem pendeteksi posisi plat nomor kendaraan menggunakan software Matlab. Matlab merupakan perangkat lunak produk dari The MathWork, Inc. yang memadukan kemampuan perhitungan, pencitraan, dan pemrograman dalam satu paket [2] Kedua, pengenalan karakter "B" tidak berhasil dilakukan oleh transformasi hit or miss. Gagalnya pengenalan tersebut disebabkan kurang tegasnya karakter "B" dalam bentuk binerisasi sehingga transformasi hit or miss tidak mampu bekerja secara optimal.…”

Abstrak: Penelitian ini dikembangkan sebuah sistem pendeteksi posisi plat nomor kendaraan yang ditampilkan pada GUI Matlab. Pendeteksian posisi plat nomor kendaraan menggunakan dua metode, yaitu metode transformasi hough dan transformasi hit or miss. Tahap pengolahan citra yang digunakan meliputi: binerisasi, aras keabuan, deteksi tepi, pemotongan citra, filtering, dan resizing. Keefektifan sistem ini diukur dengan perhitungan terhadap nilai perolehan (recall) dan nilai ketepatan (precision). Berdasarkan hasil penelitian didapatkan bahwa sistem berhasil mendeteksi posisi plat nomor kendaraan dengan tingkat keberhasilan pendeteksian sebesar 76% untuk nilai threshold 0,75, 72% untuk nilai threshold 0,8 dan 48% untuk nilai threshold 0,85. Hasil penelitian juga menunjukkan nilai rata-rata recall sebesar 54% untuk nilai threshold 0,75, 50% untuk nilai threshold 0,8 dan 40% untuk nilai threshold 0,85, sedangkan nilai rata-rata precision sebesar 14% untuk nilai threshold 0,75, 14% untuk nilai threshold 0,8 dan 12% untuk nilai threshold 0,85.Kata kunci: Trasnformasi Hough, Transformasi Hit Or Miss, Recall, Precission. Abstract: This research was developed a detection system of vehicle license plates that displayed at the GUI Matlab.
