Abstract

Abstrak. Praktikum Gerak Lurus Beraturan (GLB) dan Gerak Lurus Berubah Beraturan (GLBB) yang umum digunakan yaitu dengan menggunakan set alat pesawat Atwood. Pengoperasian alat ini biasanya masih dilakukan secara tradisional menggunakan stopwatch. Seringkali praktikum yang dilakukan dengan alat tradisional menghasilkan data yang kurang akurat, sehingga perlu dikembangkan set alat yang beroperasi secara otomatis. Set alat otomatis yang dapat dikombinasikan dengan pesawat Atwood  diantaranya yaitu sensor IR-LED dan software pengolahan citra TRACKER. Penelitian ini dilakukan untuk mencari tahu perbedaan keakuratan antara sensor IR-LED dan software TRACKER dalam analisis GLB dan GLBB menggunakan pesawat Atwood. Penelitian ini dilakukan sebanyak 10 kali pada setiap alatnya. Didapati hasil, rata-rata kecepatan 46,89 cm/s untuk analisis menggunakan sensor IR-LED dan 48,35 cm/s untuk rata-rata kecepatan analisis menggunakan software TRACKER. Sedangkan rata-rata percepatan yang terukur adalah 59,42 cm/s² untuk analisis menggunakan sensor IR-LED dan 54,85 cm/s² untuk analisis menggunakan software TRACKER. Perbedaan hasil pengukuran dari kedua percobaan dapat disimpulkan bahwa terdapat perbedaan keakuratan antara sensor IR-LED dan software TRACKER yang digunakan untuk menganalisis GLB dan GLBB pada pesawat Atwood. Kata kunci: Pesawat Atwood, IR-LED, pengolahan citra, TRACKER.Abstract. Practicum of Uniform Motion (GLB) and Uniformly Changing Motion (GLBB) which are commonly used are using the Atwood plane tool set. The operation of this tool is usually still done traditionally using a stopwatch. Often practicums carried out with traditional tools produce less accurate data, so it is necessary to develop a set of tools that operate automatically. Sets of automatic tools that can be combined with Atwood aircraft include IR-LED sensors and TRACKER image processing software. This research was conducted to find out the difference in accuracy between the IR-LED sensor and the TRACKER software in the analysis of GLB and GLBB using the Atwood aircraft. This research was carried out 10 times on each tool. The results showed that the average speed was 46.89 cm/s for analysis using the IR-LED sensor and 48.35 cm/s for the average speed of analysis using TRACKER software. While the average acceleration measured is 59.42 cm/s² for analysis using IR-LED sensors and 54.85 cm/s² for analysis using TRACKER software. The difference in the measurement results of the two tools, concluded that there was a difference in accuracy between the IR-LED sensor and the TRACKER software used to analyze GLB and GLBB on Atwood aircraft.Keywords: Atwood aircraft, IR-LED, image processing, TRACKER

Abstract

Refrigeration systems are an essential need in everyday life. There are lots of modern industry that uses refrigerator for helps maintain temperature stability from overheating and prevents the product from drying out protected from dirt and insect attacks. However, the refrigeration system used in industry still uses a refrigeration system vapor compression and using chlorofluorocarbon (CFC) refrigerant and hydro-chlorofluorocarbons (HCFCs) which are harmful to the environment. Therefore, it requires thermoacoustic cooling generated by the engine single-stage thermoacoustic. This research was conducted numerically. In this research, the effects are simulated stack porosity on the performance of thermoacoustic cooling generated by a single-stage thermoacoustic machine at 0°C. the porosity was varied from 0.37 to 0.97. It was found that the stack porosity was optimal when the porosity is 0.97 and the performance of the cooler is 52 %. Moreover, the lowest heating temperature for the thermoacoustic machine is 217°C. This temperature can be used for waste heat recovery.

Abstract

Era digital pada industri 4.0 telah membawa banyak perubahan dalam berbagai aspek kehidupan. Beberapa perubahan yang dimaksud meliputi cara berkomunikasi, akses ke informasi, dan penggunaan berbagai bentuk media dalam kegiatan sehari-hari. Perkembangan teknologi ini juga berdampak pada sistem pendidikan dan salah satu teknologi yang sangat memberi dampak adalah penggunaan digital learning. Sekolah Menengah Pertama Negeri (SMPN) 3 Semarang sebagai Mitra Lembaga Penelitian dan Pengabdian kepada Masyarakat (LPPM) Universitas PGRI Semarang menyadari pentingnya meningkatkan kemampuan para guru dalam menerapkan digital learning dalam proses pembelajaran di kelas.  Untuk membantu Mitra PKM UPGRIS dalam mencapai tujuan peningkatan SDM Pendidikan di sekolah tersebut, Tim Pengabdian kepada Masyarakat (PKM) ini perlu menyelenggarakan in-house training  Model Pembelajaran berbasis digital. Tujuan dari kegiatan PKM ini adalah untuk memberikan pelatihan atau pembelajaran kepada para guru di SMPN 3 Semarang.  Kegiatan diawali dengan diskusi tentang kondisi SDM pendidikan di SMPN 3 Semarang yang dilanjutkan dengan identifikasi kebutuhan dan jenis kegiatan yang diperlukan berupa pelatihan atau pembelajaran berbasis digital.  Bentuk kegiatan PKM ini adalah workshop berupa pemberian ceramah atau kuliah dan pendampingan perencanaan pembelajaran berbasis digital learning kepada para guru. Luaran yang diharapkan dari kegiatan PKM ini adalah perangkat pembelajaran kreatif berupa model pembelajaran dan media pembelajaran digital yang tepat yang dihasilkan para guru untuk diimplementasikan dalam proses kegiatan belajar mengajar di SMPN 3 Semarang.

Abstract

Science teachers of the Blora Regency MGMP experienced obstacles in creating IT-based learning media. The purpose of this PKM activity is to provide assistance to science teachers in creating IT-based learning media for the science learning process in junior high schools as part of teacher professional development. The methods used in this activity are socialization, workshops, and mentoring. Socialization is carried out to agree on the implementation of community service. The workshops that will be implemented include: Designing IT-based interactive learning media with a deep learning approach, Creating AI-based interactive learning media, Utilizing PheT-based interactive learning media, and implementing interactive learning media. In addition to the workshop, this community service activity also provides assistance in creating IT-based media starting from the stage of analyzing media needs, creating AI-based media, and PheT. This activity was carried out for 32 hours of lessons and monitoring the use of learning media by Blora Regency MGMP Science teachers. The results of the community service showed that all participants were able to utilize AI and PhET Simulation in preparing learning media. This was shown in the learning media that had been prepared by participants after completing the community service.

Abstract

This study aims to determine the effect of Problem Based Learning (PBL) model assisted by PhET Simulation with Deep Learning approach on student learning outcomes on dynamic fluid topic. The research used a quantitative approach with a quasi-experimental design. The subjects consisted of two XI classes in one of the randomly selected high schools in Semarang. The experimental class used the PBL model combined with PhET simulation to fill in the Learner Worksheet (LKPD) related to the discharge and continuity equations, while the control class did not use PhET and did not fill in the LKPD. Both classes were then given a learning outcome test. The results of the analysis using the Mann-Whitney test showed a significant difference between the learning outcomes of the two classes (U = .000, Z = -5.737, p < 0.001), with the experimental class scoring higher (M = 80) than the control class (M = 19). These findings show that the PBL model assisted by PhET Simulation and a deep learning approach improved student learning outcomes. The conclusion of this study is that the application of PBL model assisted by PhET Simulation and Deep Learning approach effectively improves student learning outcomes on dynamic fluid topic.
