Abstract

The purpose of this study was to determine the characteristics, feasibility, and effectiveness of the E-module of additives and addictive substances based on problem-based learning in order to improve students' ability to think critically. The type of research used is development research, which refers to the Borg and Gall development model which is modified and adapted to conditions in the field into 9 stages, namely: 1) needs analysis and information gathering, 2) potential problems in the field, 3) product design, 4) design validation, 5) product design improvement, 6) limited trial, 7) product revision, 8) operational field test, 9) E-module final product. The data analysis technique used is a descriptive analysis which is used to describe the characteristics of the developed E-module, the feasibility analysis of the E-module is based on the N-gain score obtained, the results of this study found that the problem-based learning-based E-module has been successful developed according to the problem-based learning model to improve the ability of students to think critically. Problem-based learning-based E-modules are very feasible to be used in the process of learning activities in order to improve students' critical thinking skills. E-module of additives and addictive substances based on problem-based learning has been effective in improving the ability of students to think critically which is marked by an increase in students' pretest and posttest scores, and based on the average result of the N gain score of 0.76 which is included in the very decent category

Abstract

Pandemi Covid-19 mendasari pemerintah mengeluarkan kebijakan Belajar Dari Rumah (BDR) yang mendesak institusi penyelenggara pendidikan untuk mengubah pengelolaan pembelajarannya secara online. Pasca Covid-19, model pembelajaran yang mengintegrasikan dengan pembelajaran online, seperti pembelajaran hybrid (campuran), masih banyak diminati karena keuntungan yang tidak dibatasi tempat dan waktu. Namun beberapa permasalahan muncul selama pelaksanaannya, diantaranya pembelajaran yang kurang interaktif dan belum terstruktur. Hal ini dikarenakan belum tersedianya platform yang tepat dan kurangnya kemampuan guru dalam mengelola kelas pembelajaran online. Oleh karena itu, perlu adanya upaya peningkatan kemampuan guru dalam pengelolaan pembelajaran online berupa pendampingan peningkatan kemampuan guru dalam mengembangkan kualitas pembelajaran dan media pembelajaran online yang tepat. Kegiatan pengabdian ini melibatkan 2 sekolah mitra di Kota Surakarta, diantaranya SMP IT Nur Hidayah dan SMP Batik Program Khusus Surakarta. Tujuan dari kegiatan ini diantaranya 1) memberikan pemahaman kepada guru terhadap pembelajaran dan media pembelajaran yang dapat diintegrasikan secara online, 2) melatih guru dalam mengembangkan kemampuan pengelolaan kelas berbasis Moodle, dan 3) meningkatkan kemampuan guru dalam menyusun media pembelajara online. Metode pelaksanaan yang digunakan berupa ceramah, diskusi, dan praktik yang dilakukan selama 3 hari dan dihadiri peserta 10 peserta dari SMP Batik Program Khusus dan SMP IT Nur Hidayah. Hasil evaluasi pasca pendampingan didapatkan bahwa 1) 100% guru telah memiliki akun sebagai Teacher di web belajarsains-uns.com, 2) 80% guru telah melengkapi 10 aktivitas yang diinstruksikan, dan 3) umpan balik yang baik. Melalui website yang dibuat, selain mendapatkan pemahaman baru, guru dapat memanfaatkannya selama pelaksanaan pembelajaran daring, luring, dan hybrid.

Abstract

As a branch of fundamental science, physics studies the laws underlying physical events that happen in nature. To learn physics, laboratory activity is necessarily involved, and it requires supporting devices to observe and study phenomena that are physically abstract, such as heat transfer mechanisms. This research aims to develop an Internet of Things (IoT) experiment device for heat transfer using NodeMCU and describe its working principle and measurement result. It involved NodeMCU, MAX6675 sensor, and LCD 1602 as the main components. The procedures carried out in this research included planning, developing, testing, data collecting, data analyzing, and reporting. Multiple measurements were carried out to analyze the standard error value of the device. The standard error values of both thermocouples used in the device were 1,336104 for the first thermocouple and 0,754315 for the second. Additionally, the IoT device’s thermocouple readings were calibrated using the linear regression method and the validation experiment showed that the calibration has increased its accuracy value.
