CT skills are one of the skills required by students in facing the real world problems in 21st century era. They can be trained by using several approaches in science learning context. However, there is a little study focused to investigate the impact of IA toward CT skills. This present study investigated the implementation of IA to enhance students’ CT skills. The experimental study, which was one group pretest posttest design, has been conducted to garner data from participants. There were 36 students (grade XI) who contributed as participants and they came from one public senior high school in Indonesia. In order to obtain data, an instrument related to CT skills was developed dealing with physics concepts. This finding revealed that students’ CT skills enhanced in medium category based on normalized gain (N-gain). A consideration of the implication of this present study is a deep insight in students’ CT skills in Indonesian high schools.

The purpose of this study is to acquire depiction of cognitive ability enhancement which the laboratory activities based inquiry implanted argumentation activities was conducted as a main process in the classroom activities. A quasi experiment method with non-equivalent control group pretest-post-test was carried out to implement this treatment. The participants of this study were students grade XI in one of public senior high schools in Indonesia. They were divided into two groups, experimental and control group, using purposive sampling. Experimental group was provided great opportunities to conduct laboratory activities based inquiry implanted argumentation activities while control group uses laboratory activities based inquiry. In order to recognize the cognitive ability of students, an instrument was developed in form of multiple choices. This study revealed that the mean difference of two groups was significantly different in which students’ cognitive ability of experimental group was higher than this control group and was in medium criteria from normalized gain perspective. From this findings, implanting argumentation activities on inquiry lab played prominent role in constructing model and theory of knowledge for students in enhancing their cognitive abilities.

Cookbook experiment is familiar type of experiment in which students have to follow some procedures to carry out a practicum in laboratory. Due to its easiness, not only students in high school but also students in college recognized this. However, there is no clear role of cookbook experiment toward learning outcomes of pre-service physics teachers. This study investigates the impact of cookbook experiment toward learning outcomes. A single case study was carried out in one private university in east Indonesia in which all participants were students from physics department. The finding results reveals that cookbook experiment was used almost eight years. This affected two pivotal aspects of students: achievement of cognitive learning ability and students’ interest toward learning process. In these aspects context, the cookbook experiment did not facilitate students who are pre-service physics teachers to construct and strengthen deep understanding, to make a joyful and meaningful learning process, and to flourish the diverse skills needed by students such as higher order thinking skills. This article indeed presents a consideration of the implication of physics practicum in Indonesia in deep insight and wider context.

Pada awal masuknya covid di wilayah kota Bima pada bulan maret, terdapat sejumlah orang mengalami gejala covid bahkan ada beberapa orang yang terjangkit positif virus tersebut. Oleh karena perlunya masyarakat diberi informasi salah satu cara untuk memanimalisir penyebaran virus yaitu dengan membuat alat desinfektan otomatis, karena sistem untuk membunuh bakteri, virus, kuman, dan mikroorganisme, salah satunya yaitu COVID-19 yang merupakan penyakit menular oleh sindrom pernapasan akut coronavirus berbahaya lainnya. Alat disinfektan ini otomatis merupakan sebuah cara atau proses penggunaan sebuah mesin, sistem control, atau sebuah teknologi informasi untuk mempermudah masyarakat supaya tidak menyemprot secara manual. Desinfektan adalah cairan pembersih yang umumnya dibuat dari hidrogen peroksida, creosote, atau alkohol yang bertujuan menggunakan sensor ultrasonic HC-SR04 untuk mendeteksi jarak suatu objek dengan control Arduino Uno. Penelitian ini bertujuan untuk membuat rancangan alat disinfektan otomatis berbasis mikrokontroler dalam pencegahan penyebaran Covid-19 di program studi pendidikan fisika. Metode yang digunakan ialah metode eksperimen dimana pengujian alat dan pengambilan data dilakukan dengan cara pengulangan, pada percobaan jarak 10 cm didapatkan waktu respon selama 0,1s, 0,1s, 0,1s, 0,1s, 0,1s dengan nilai debit air 0,022 L/s, 0,024 L/s, 0,02 L/s, 0,018 L/s, 0,021 L/s dengan indikator relay dan pompa menyala sebanyak 5 kali. Kinerja pengujian alat menunjukkan bahwa sistem kerja rangkaian alat desinfektan otomatis yang didasarkan objek terhadap manusia yang memiliki sistem input yang terhubung pada Mikrocontroler, sistem yang dimiliki yakni sensor Ultrasonik sebagai input sistem yang otomatis yang bertanggung jawab terhadap pembacaan objek pada saat manusia terdeteksi di depan sensor melalui gelombang Ultrasonik yang dihasilkan objek tersebut. Mikrokontroler mendapat input dari sensor Ultrasonik kemudian akan diteruskan di relay yang menghasilkan output berupa pompa air yang menyala yang akan di semprotkan pada suatu objek. Berdasarkan hasil penelitian jarak 40 cm dapat dikatakan efektif, karena terdapat standar deviasi  waktu ialah 0 dan standar deviasi pada debit air yang rendah. Disarankan dalam merangkai alat, pastikan semua modul dan sensor terpasang dengan benar sesuai dengan program yang dibuat, dan menggunakan pompa yang memiliki tekanan keluaran air yang besar untuk menyemprotkan cairan desinfektan.
