The research aims to determine the effect of applying Quizizz media as a learning medium on increasing students' interest and learning outcomes. The type of research used in this study was a quasi-experimental design with nonequivalent control group design. The sampling technique used was saturated sampling with a total of 42 respondents in each of the experimental and control groups, the instruments used were questionnaires and tests in the form of multiple choices. Data were analyzed using descriptive and inferential statistical tests, namely through the t-test with values obtained t-count = 7.026 with a value of t-table = 2.021 so that it can be concluded that the value of t-count ˃ t-table is 7.026 ˃ 2.021 or it can be said that H-0 is rejected and H-a is accepted in learning interest while in learning outcomes obtained value t-count = 3.055 and t-table = 2.021 so that it can be concluded that the value of t-count ˃ t-table is 3.055 ˃ 2.021 or it can be said that H-0 is rejected and H-a is accepted. Based on the average score, it shows that there is an influence on the use of Quizizz media as a learning medium which is shown in changes in student behavior after the media is applied, such as starting to actively ask questions during the learning process, doing assignments given by the teacher, and not getting sleepy during learning activities. so based on this the use of Quizizz media as a learning medium is appropriate to use in increasing interest which can then improve student learning outcomes.

This study aims to examine the effect of media exposure, environmental performance, profitability, company size on disclosure of carbon emissions. The research population includes all companies on the Indonesia Stock Exchange (IDX) for the 2017-2021 period. The sample in the study was determined by purposive sampling technique and 18 companies were found over a period of 5 years, resulting in 90 research samples. The analytical method used is Panel Data Regression Analysis. The results of the study show that media exposure, environmental performance and company size have a positive effect on disclosure of carbon emissions, while profitability has no effect on disclosure of carbon emissions. The limitation of this research is that this research only focuses on manufacturing companies that have been listed on the Indonesia Stock Exchange (IDX), so that it cannot describe the condition of the population of all companies in Indonesia so that it can provide different results if carried out in different industries. The results of this study are expected to pay more attention to the company's environmental impact by increasing disclosure of environmental information related to greenhouse gas emissions because it can be added value to the company for stakeholders or investors.

Currently technology is highly developed and supports many new innovations. The most innovation is wireless technology and voice recognition. One of the widely used wireless technology is Bluetooth. By utilizing Bluetooth connectivity and voice recognition applications on smart phones, it can be used to control electronic equipment. In this study, voice recognition applications and Bluetooth connections will be used on smart phones to control electric wheelchairs. This research begins with designing an electric wheelchair. For Bluetooth communication using the HC-05 Bluetooth module. The wheelchair was developed by modifying conventional wheelchairs to become electric. The user or patient will control the wheelchair using his smart phone through the voice recognition application. Commands in the form of voice that will be sent by the smart phone and received by the HC-05 Bluetooth module, then become input for the Arduino microcontroller. The microcontroller will then process the input data and will instruct the motor driver to give instructions to the wheelchair driving motor. The electric wheelchair's voice control system with a Bluetooth connection can work quite well. The Bluetooth connection used in this electric wheelchair voice control system works optimally and well at a distance of <10 meters, the connection starts to drop at a distance of 10 to 23 meters, and the connection is lost when the distance is 30 meters. The results of the voice recognition test on voice commands were successful with an accuracy of 85%. The total test is 100 orders with a total error of 15 orders.

The use of voting rights in a general election is the subjective right of citizens (people) who have qualified to vote, but from the aspect of the interests of the state and nation, it can be considered that the use of voting rights / voting rights of citizens in general elections, in essence is a form of responsibility to participate in the administration of government. However, at the current level of reality there is a tendency for people to experience "frustration" and "political lethargy" to exercise their sovereignty through the mechanism of elections. This fact is due to the fact that people feel that their aspirations cannot be accommodated after the general election and presidential election. In addition, there is the influence of pressure groups (especially groups that want the disintegration of the nation and the Unitary State of the Republic of Indonesia) so that people better abstain and become "white groups". Therefore, a directed and effective government legal policy is needed to increase legal awareness of citizens participating in exercising their active voting rights in general elections and presidential elections.

Pada umumnya para nelayan di Batam telah beralih dari menangkap ikan dengan kapal pukat menjadi nelayan yang menggunakan keramba jaring untuk membudidayakan Ikan Bawal Bintang.Keramba adalah nama kolam ikan yang terbuat dari jaring untuk menampung ikan hasil budidaya, masalah yang sering terjadi pada Ikan Bawal Bintang. kasus penyakit yang disebabkan oleh berbagai sebab. Dan masih banyak ketidaktahuan nelayan akan jenis penyakit yang menyerang Ikan Bawal Bintang tersebut yang mengakibatkan nelayan tidak mengetahui cara pengobatan dan pencegahan terhadap penyakit tersebut. Karena permasalahan tersebut maka penggunaan metode case-based reasoning (CBR) memberikan solusi berupa sistem pakar, dimana metode tersebut menggunakan kemiripan dari setiap penyakit ikan yang akan diteliti. Tujuan akhir dari penelitian ini yaitu nilai persentase kesamaan serta saran berupa saran dan solusi yang akan dilaksanakan oleh para nelayan. Kata Kunci : Sistem Pakar, Case Base Reasoning, Penyakit Ikan Bawal Bintang, Nelayan.

Kinematika merupakan salah satu topik dalam fisika yang membahas tentang gerak sebuah benda pada lintasan lurus. Topik ini menjadi dasar untuk mempelajari topik lain seperti gerak melingkar, parabola dan rotasi. Siswa mempelajari topik ini sejak sekolah menengah hingga perguruan tinggi. Jadi tujuan penelitian ini adalah untuk menganalisis kemampuan siswa menyelesaikan tes representasi gerak lurus dengan melibatkan tiga bentuk representasi yakni tabel, grafik, dan formula. Penelitian survey dilakukan untuk mengukur kompetensi representasi siswa dengan melibatkan 8 sekolah menengah atas (SMA) di kota Pontianak. Sebanyak 672 siswa terlibat dalam penelitian ini untuk menjawab tes sebanyak 24 butir berbentuk pilihan ganda. Jawaban siswa yang benar diberi skor 1 dan jawaban yang salah diberi skor 0 kemudian dikonversi ke skor 100. Hasil penelitian menunjukkan bahwa skor rata-rata kompetensi representasi siswa adalah 43.64 dengan kategori sedang. Persentase siswa pada kategori tinggi, sedang, dan rendah berturut-turut adalah 14.88%, 36.14%, dan 48.96%. Selanjutnya skor kompetensi representasi siswa paling tinggi yakni dari grafik ke tabel (57.07) sedangkan yang paling rendah adalah 35.65 dari formula ke grafik. Skor kompetensi representasi siswa berada di bawah 50 jika melibatkan representasi formula. Ini mengindikasikan bahwa siswa mengalami kesulitan dalam mentransformasi formula. Hasil penelitian juga menunjukkan bahwa siswa tidak mampu menentukan slope positif atau negatif dari data posisi yang diberikan. Untuk itu pendidik harus memberikan perhatian khusus ketika mengajarkan konsep gerak lurus yang melibatkan tabel, grafik dan formula serta konsep slope.
