ANALISIS PERILAKU SOSIAL EMOSIONAL MAHASISWA PGSD SAAT PEMBELAJARAN DALAM JARINGAN
Get PDFThe covid pandemic period still lingers and causes learning to be carried out online even though 20% - 50% of the total number of planned meetings. Online learning also has an impact on the development of student behavior, such as emotional social attitudes. This study aims to determine the impact of online learning on social emotional attitudes that arise in students. This research uses descriptive qualitative method by applying driven theory technique. Data was collected by means of interviews with students. The results obtained, online learning raises students' emotional social attitudes, namely the lack of socialization between students with one another; each student's emotions tend to feel bored during online lectures; and students are less disciplined. It is hoped that this research can provide an overview of the preparation and planning of online lectures
Pengaruh Model Problem Based Learning pada Pembelajaran Fisika Siswa SMA
Get PDFThis research is motivated by the problems that the researchers obtained, namely the low learning outcomes of students' physics due to the lack of active involvement and independence of students in learning. The problem in this study is whether there is an effect of the Problem Based Learning model on physics learning for high school students. The purpose of this study was to determine the effect of the Problem Based Learning model on physics learning for high school students. This type of research is a real experimental research, the research design is in the form of control-group pretest-posttest. The population of this study was all students of class X SMA Negeri Purwodadi, Musi Rawas Regency for the 2018/2019 academic year, totaling three classes. The sample is class X.1 totaling 42 students and class X.3 students totaling 36 students. The data collection technique used is test. The data obtained were analyzed using t-test. Based on the results of the t-test analysis for the final test at the significance level = 0.05, it was obtained tcount > ttable (tcount = 2.65 > ttable = 1.67), so it can be concluded that there is an influence of the Problem Based Learning model on Physics learning for high school students.Penelitian ini dilatarbelakangi oleh permasalahan yang peneliti peroleh yaitu masih rendahnya hasil belajar fisika siswa karena kurangnya keterlibatan dan kemandirian siswa secara aktif dalam pembelajaran.

Desain Lampu Utama Mobil dengan Filter Polarisator sebagai Anti Silau
Get PDFThe lamp is a part that has an important function on the vehicle. The function of this section is to illuminate the road, besides that the use of lights must also provide comfort for the driver, meaning that it does not give a glare effect when used. This glare effect is caused because light has a diffuse nature. Therefore, the use of a polarizing filter can convert the light into polarized light. The purpose of this research is to design an anti-glare product using a polarizing filter. The design will be tested for feasibility through a questionnaire containing polarizer explanation materials, product design drawings, and product assessment statements. The method used in this study is a 4D model using two stages of development, namely define and design. The results of the study in terms of the suitability of the type of lamp used obtained very decent results, the percentage of 84.4%, while in terms of the feasibility of the polarized filter on the lamp obtained very decent results with a percentage of 90.6%. To find out more about the feasibility of the designs made, further research is needed in the form of making products to be tested for feasibility.Lampu merupakan bagian yang memiliki fungsi penting pada kendaraan. Fungsi dari bagian ini adalah untuk menerangi jalan, disamping itu penggunaan lampu harus juga memberikan kenyamanan bagi pengendara artinya tidak memberikan efek silau ketika digunakan. Efek silau ini disebabkan karena cahaya memiliki sifat menyebar. Oleh karena itu, pemanfaatan filter polarisasi dapat mengubah cahaya tersebut menjadi cahaya terpolarisasi. Tujuan dari penelitian ini adalah mendesain produk anti silau dengan pemanfaatan filter polarisasi. Desain akan diuji kelayakannya melalui angket berisi materi penjelasan polarisator, gambar desain produk, dan pernyataan penilain produk. Metode yang digunakan dalam penelitian ini yaitu model 4D dengan menggunakan dua tahap pengembangan yaitu define ( pendefinisian), dan design (perancangan)Hasil penelitian dari segi segi kesesuaian jenis lampu yang digunakan memperoleh hasil sangat layak persentase 84,4%, sedangkan dari segi kelayakan filter polarisasi pada lampu memperoleh hasil sangat layak dengan persentase 90,6%. Untuk mengetahui lebih lanjut kelayakan dari desain yang dibuat perlu adanya penelitian lanjut berupa pembuatan produk untuk diuji coba kelayakannya.
 
Model Pembelajaran Problem Based Learning sebagai Implementasi Aliran Konstruktivisme Pada Pembelajaran Sejarah
Get PDFThe learning pattern developed today is the student center. The emergence of a model of learning problem based learning is also a suggestion for developing that learning pattern. In the model of learning problem based learning all learning processes are centered on students. The teacher only functions as a facilitator that helps students accomplish the prescribed learning purpose before the learning begins. Researchers see an implementation of a school of constructive flows on a model based learning problem. The context discussed is history learning. Based learning model based learning asan implementation of a constructive stream on history study. This discussion uses a library study method that is through books and journals

This article describes the history of the Pajang Sultanate during the reign of Sultan Hadiwijaya (1549-1582). This article aims to add insight or knowledge about the Pajang sultanate during the reign of Sultan Hadiwijaya (1549-1582). By using the method of writing that is qualitative. The Pajang Sultanate is the successor of the Demak Sultanate which collapsed due to conflicts occurring within the family environment. Jaka Tingkir, who defeated Arya Penangsang, then moved all the royal heirlooms in Demak to Pajang. The transfer of power from the coastal areas to the inland areas caused a change in the nature of the kingdom which was originally maritime to become agrarian. However, during the reign of Jaka Tingkir, the Pajang Sultanate experienced progress in all aspects of life including, the economic aspect, the Pajang Sultanate in the 16th and 17th centuries became a rice barn, in the arts, there were new types of puppets with sizes smaller than the size. Wayang in general is the Kidang Kencana puppet, in the political field the application of politics is open to all groups in Pajang and in the religious field Jaka Tingkir uses the teachings of Sunan Kalijaga by utilizing cultural traditions, namely the art of puppets to carry out da'wah against the spread of Islam

Get PDFThis study aimed to determine the phytochemical content and potency of the ethanol extract of lemongrass (Cymbopogon citratus) stem and red galangal rhizome (Alpinia purpurata) in inhibiting the growth of Shigella sonnei in vitro. Phytochemical testing of ethanol extract using Thin Layer Chromatography (TLC). Antibacterial test was carried out by applying the Kirby Baeur disk diffusion method with swab technique with a series treatment of extract concentrations of 6.25%, 12.5%, 25%, 50%, positive control (tetracycline 20%), and negative control (DMSO 10%) with 5 replicates. From the results of phytochemical tests, showed that secondary metabolites of flavonoids and terpenoids were found in red galangal extract. While the lemongrass extract showed positive results for alkaloids, flavonoids, terpenoids and phenolic compounds. The ethanol extract of lemongrass stem and galangal rhizome potential as an antibacterial with the highest inhibitory activity obtained at a concentration of 50% in both lemongrass and galangal extracts, respectively 8.4 mm and 7 mm. The results of the antibacterial test showed that red galangal extract and lemongrass extract had phytochemical contents that could inhibited the growth of S. sonnei
