The learning process at the time COVID-19 must be implemented online. The use of media in learning is very important. The whatsapp application was chosen to be used in this online learning. This study aims to obtain information about the application of the WhatsApp application in online learning and to find out what are the advantages and disadvantages of using the WhatsApp application in online learning. The research subjects here are the teachers and students of SD Yapita Surabaya and the object under study is the use of the WhatsApp application in online learning. This study used a qualitative research design. The instruments used in this study were observation, surveys and interviews. The results obtained are that the application WhatsApp can be applied in the learning process online and there are also deficiencies in its application, namely the existence of obstacles regarding face-to-face implementation through the existing features of the WhatsApp application and the absence of features to limit student work time and for the advantages the WhatsApp application is able to accommodate the implementation of the learning process well.
Penelitian ini bertujuan untuk menganalisis tingkat efektivitas model pembelajaran PjBL (Project Based Learning) dalam meningkatkan kemampuan literasi numerasi dan literasi digital pada peserta didik madrasah ibtidaiyah. Pendekatan yang digunakan adalah kuantitatif dengan metode eksperimen dan desain penelitian yang digunakan adalah control group pretest-posttest design. Dengan menggunakan teknik random sampling, diperoleh sampel untuk kelas eksperimen dan kontrol. Pada kelas eksperimen diberikan perlakuan dengan model pembelajaran PjBL (Project Based Learning) dan pembelajaran konvensional dengan metode ceramah pada kelas kontrol. Data kemampuan literasi numerasi dan literasi digital tersebut diperoleh menggunakan tes tulis berupa angket yang didukung oleh pemberian soal pilihan ganda dan benar-salah pada peserta didik. Hasil dari penelitian yaitu penggunaaan model pembelajaran PjBL (project-based learning) efektif digunakan dalam meningkatkan kemampuan literasi numerasi dan literasi digital pada peserta didik kelas V MI Al-Fithrah Surabaya. Dengan perolehan nilai signifikansi sebesar 0,107 < 0,05 menunjukkan hasil bahwa terdapat pengaruh yang signifikan dari variabel independent (X) terhadap semua variabel dependen (Y1 dan Y2). Hal ini terlihat pada pengaruh yang terjadi di kelas eksperimen yang diberikan perlakuan model pembelajaran PjBL (project-based learning) lebih unggul dibandingkan dengan kelas kontrol yang menggunakan model pembelajaran konvensional.
Scheduling is one of the important part in production planning process. One of the factor that influence the smooth production process is raw material supply. Sugarcane supply as the main raw material in the making of sugar is the most important componen. The algorithm that used in this study was Simulated Annealing (SA) algorithm. SA apability to accept the bad or no better solution within certain time distinguist it from another local search algorithm. Aim of this study was to implement the SA algorithm in scheduling the sugarcane harvest process so that the amount of sugarcane harvest not so differ from mill capacity of the factory. Data used in this study were 60 data from sugarcane farms that ready to cut and mill capacity 1660 tons. Sugarcane harvest process in 19 days producing 33043,76 tons used SA algorithm and 27089,47 tons from factory actual result. Based on few experiments, obtained sugarcane harvest average by SA algorithm was 1651,63 tons per day and factory actual result was 1354,47 tons. Result of harvest scheduling used SA algorithm showed not so differ average from mill capacity of factory. Truck uses scheduling by SA algorithm showed average 119 trucks per day while from factory actual result was 156 trucks. With the same harvest time, SA algorithm result was greater and the amount of used truck less than actual result of factory. Thus, can be concluded SA algorithm can make the scheduling of sugarcane harvest become more optimall compared to other methods applied by the factory nowdays.
Penelitian ini memaparkan tetaang pengembangan konten pembelajaran IT berbasis Total quality management yang dilakukan di SD Teladan Yogyakarta. Pada masa Covid 19 lembaga pendidikan dituntut untuk mampu memaksimalkan proses pembelajaran IT, dengan tujuan materi dapat tersampaikan dengan baik, akan tetapi pada kenyataannya banyak lembaga pendidikan yang tidak mampu dalam memaksimalkan teknologi IT dalam proses pembelajaran. Oleh sebab itu perlu adanya pendekatan yang baik dalam proses perencanaan pembelajaran IT, salah satunya adalah dengan Total Quality Management Penelitian ini menggunakan pendektakan kualitatif deskriptif dengan jenis studi kasus. Hasil penelitian menujukan bahwa SD Teladan Yogyakarta melakukan beberapa tahapan dalam pengembangan konten pembelajaran IT yang berbaisis Total quality management, tahpan tersebut antara lain, penentuan standar (input), hasil monitoring dan perbandingan dengan standar (proses), perbaikan penyipangan (output) dan usulan standar baru (outcome).
