Online learning has been chosen to be applied in all tertiary institutions in Indonesia; this also applies to IAIN Takengon. Student perception is one of the determinants of the success of the learning that is carried out. The purpose of writing this article is to find out how students' perceptions of online learning have been implemented and the factors that influence these perceptions. The research method used is an online survey using google form. The results showed that students' perceptions of online learning were not very good; this was caused by several factors, such as poor internet access, burdensome internet quota, difficulty communicating with lecturers, so students were not ready to use applications when online learning was carried out. There needs to be much improvement in the online learning system implemented; this indicates that universities are not ready to carry out online lectures.

The COVID-19 pandemic has an overwhelming impact on the nursing profession. Nurses play a vital role before and during pandemics, with nurse leaders taking the lead in preparation for outbreaks. In response to an outbreak, early recognition and preparation for the increasing threat, managing staffing challenges together with the well-being of nurses are of utmost importance. Strategies to promote physical distancing while not compromising continuing nursing education and patient care are also essential. With prompt actions and coordinated efforts, risk of spreading the virus within the healthcare sector can be kept at the minimum. As nurses are in the frontline of healthcare, their confidence in being wellsupported by the hospital should be maintained. This case report describes the preparation and response of the nurses in Singapore General Hospital to the COVID-19 outbreak in Singapore.

A good work posture is one of vital contributors to occupational health and to increase the efficiency of industrial workers. Recently, numerous research works have developed an Integrated RULA-Kinect TM system for work posture assessment; however, usability of the developed system remains unknown. The objective of this study was to develop a prototype of Integrated RULA-Kinect TM system. Additionally, this study performed usability testing on the Integrated RULA-Kinect TM system and RULA Employee Assessment Worksheet to determine feedbacks and reactions from the potential users. A focus group session was conducted among eight potential users, which divided into 2 groups (novice and expert). The results of the focus group session revealed that both novice and expert users agreed that the Integrated RULA-Kinect TM system is easy to use compared to RULA Employee Assessment Worksheet. This study concluded that the Integrated RULA-Kinect TM system is able to counter some limitations of the RULA Employee Assessment Worksheet.

Kemampuan pemecahan masalah merupakan salah satu tujuan atau kompetensi yang akan dicapai dalam pelajaran matematika. Semua pemecahan masalah melibatkan beberapa informasi dan untuk mendapatkan penyelesaiannya digunakan informasi tersebut. Informasi-informasi ini pada umumnya merupakan konsep-konsep atau prinsip-prinsip dalam matematika salah satunya pada sistem persamaan linear dua variabel. karena akan  memudahkan siswa untuk menghitung barang belanjaan di pasar dan juga memudahkan siswa nantinya apabila akan membuat sebuah perusahan. Selain siswa kurang bisa dalam menyelesaikan soal sistem pesamaan linear dua variabel siswa juga masih kurang terampil dalam menjawab soal pemecahan masalah. Untuk itu peneliti menggukan model pembelajaran Creative Problem Solving (CPS) dalam pemecahan masalah matematis siswa. Penelitian   ini   bertujuan   untuk   mengetahui peningkatan dan perbedaan hasil belajar menggunakan model Creative Problem Solving (CPS) pada siswa kelas VIII SMP Negeri 2 Takengon. Penelitian ini menggunakan pendekatan kuantitatif dengan jenis penelitiannya yaitu quasi ekperimen, karena penelitian ini ingin mengetahui perbedaan dari kelas eksperimen dan kontrol serta ingin melihat peningkatan pada kelas eksperimen yang diberi perlakuan model pembelajaran (CPS). Penelitian yaitu dengan nilai rata-rata pada kelas yang kontrol yaitu 42,9 dan nilai rata-rata pada kelas eksperimen yaitu 53,4, yang dimana kelas tersebut berdistribusi normal. Dengan nilai uji hipotesis thitung ttabel  dimana 12,53  2,02 dengan demikian Ha diterima, sehingga terdapat perbedaan rerata kemampuan pemecahan masalah siswa. Dan hasil pengujian gain ternormalisasi diperoleh untuk kriteria gain ternormalisasi terendah 4 siswa (20%) dan dengan kriteria sedang diperoleh 16 siswa (80%), Sehingga dapat disimpulkan terdapat peningkatan kemampuan masalah siswa pada kelas VIII SMP Negeri  2 Takengon dengan model pembelajaran Creative Problem Solving (CPS).
