Abstract

Misconceptions in physics learning are often caused by students’ preconceptions that are not in accordance with the actual physics theory. The use of interactive digital technology-based learning media makes it easier for students to understands physics concepts. This research aims to apply interactive learning media based on Visual Basic for Application (VBA) excel spreadsheets to remediate misconceptions in traveling wave material. The research method is a pre-experimental design, with one group for pretest and posttest. A total of 21 samples were selected using purposive sampling technique. Data collection was carried out twice, namely during the pretest and posttest using a five-tier multiple choice diagnostic test with 10 questions. The results of the misconception remediation analysis showed a decrease in misconceptions from 28.5% to 11.3% with an average N-Gain score (-0.31). This means that there was a decrease in the percentage of misconceptions before and after treatment. This data is also supported by the results of the paired sample t-test analysis, namely 0.000 < 0.5, which means that the use of interactive learning media based on Visual Basic for Application (VBA) Excel spreadsheets has a significant effect on remediating students' misconceptions about traveling wave material. This interactive learning media is expected to be an alternative for teachers in remediating misconceptions in learning physics.

Abstract

Project Based Learning (PjBL) has many advantages but has not been widely implemented, let alone linked to entrepreneurial activities in schools. Entrepreneurship in schools, especially those taught by chemistry teachers, still has not produced crafts that link chemical knowledge therein. The aim of the research carried out was to analyze how much influence the application of the PjBL model has in improving students' creative thinking skills and entrepreneurial interest. The research method uses a one group pretest-posttest design approach. The research sample was selected using proportional sampling with data collection techniques, namely test techniques and distributing questionnaires which were then analyzed using the paired sample t test. Based on the results of the research that has been carried out, it can be concluded that there is a positive significant difference between before and after treatment. This shows an increase in students' creative thinking abilities and entrepreneurial interest after implementing the PjBL learning model.

Abstract

Live migration merupakan suatu teknik migrasi yang memindahkan server virtual machine (VM) ke server worker yang rendah CPU usage nya. Teknik migrasi ini dilakukan dengan memanfaatkan metode fuzzy mamdani sebagai pengambil keputusan berdasarkan hasil monitoring CPU usage pada masing-masing server worker. Pada setiap server worker akan ditentukan nilai batas (Threshold) yang berfungsi sebagai acuan kapan server vm akan bermigrasi ke server worker yang mengalami rendah CPU usage. Hasil pengujian yang dilakukan selama 30 menit menunjukkan bahwa teknik live migration VM dapat mengurangi konsumsi daya sebesar 0,26 Watt dibandingkan dengan tanpa teknik tersebut. Dengan demikian optimasi daya bisa terjadi jika proses migrasi server VM terlaksana dari server worker host asal ke server worker host tujuan sehingga server worker asal nantinya akan mengalami penurunan konsumsi daya atau mengalami dengan serendah-rendahnya konsumsi daya (idle).AbstractLive migration is a migration technique that moves a virtual machine (VM) server to a server worker with low CPU usage. This migration technique is carried out by utilizing the fuzzy mamdani method as a decision maker based on the results of monitoring CPU usage on each worker server. On each worker server, a threshold value will be determined which serves as a reference for when the VM server will migrate to a worker server that experiences low CPU usage. The results of tests carried out for 30 minutes show that the VM live migration technique can reduce power consumption by 0.26 Watts compared to without this technique. Thus, power optimization can occur if the VM server migration process is carried out from the original worker host server to the destination worker host server so that the original worker server will experience a decrease in power consumption or experience the lowest possible power consumption (idle).

Abstract

Treatment of dissolved mercury within water sources is crucial. This study reported the utilization and efficacy of chitosan-sulfide immobilized on dead corals (Acropora cervicornis) as an absorbent for dissolved mercury (II). Sulfide ions were immobilized on coral particles coated with chitosan (coral-Chi). Chitosan and sulfide were either mixed or stepwise immobilized on dead coral particles. The amount of mercury absorbed by this treated absorbent (coral-Chi-Na2S) was studied and compared to the control (coral only or coral-Chi). The adsorption process is a bath method within a chromatography column. The absorbent characteristics and the amount of mercury(II) absorbed were characterized. The results showed that the highest percentage of adsorption used adsorben coral-Chi-Na2S, which was 71% with an eluent flow of 0.5 mls-1 within the absorbent column. The capacity of adsorption ion Hg2+ after prior eluting in the column for 24 h contact time was 0.4057 mg/g, 0.4017 mg/g, and 0.3746 mg/g in coral-Chi-Na2S, coral, and coral-Chi respectively
