Abstract

Tuntutan kemampuan siswa dalam matematika tidak sekedar memiliki kemampuan berhitung saja, akan tetapi mampu menggunakannya dalam pemecahan masalah sehari-hari. Penelitian ini bertujuan untuk menganalisis kemampuan literasi matematis siswa kelas XI SMAN 1 Kediri. Metode penelitian yang digunakan adalah deskriptif kualitatif. Subjek penelitian terdiri dari 6 siswa dari 26 total siswa dalam 1 kelas. Penelitian ini memperhatikan faktor kemampuan awal matematis siswa (KAM). Berdasarkan hasil penelitian, 19% siswa tergolong kategori KAM tinggi dapat menyelesaikan soal rutin, menginterpretasikan masalah dan menyelesaikannya dengan rumus, melaksanakan prosedur dengan baik, mampu untuk mengatasi situasi yang kompleks serta menggunakan penalarannya dalam menyelesaikan masalah, serta siswa mampu bekerja secara efektif serta menginterpretasikan representasi yang berbeda kemudian menghubungkannya dengan dunia nyata (Level 4).Siswa yang tergolong kategori KAM sedang (66%)dapat menyelesaikan soal rutin, menginterpretasikan masalah dan menyelesaikannya dengan rumus, serta melaksanakan prosedur dengan baik (Level 3). Siswa dengan kategori KAM rendah (15%) hanya mampu menyelesaikan soal rutin (level 1). Demands on the ability of students in mathematics cannot just have the ability to count alone, but they can use it in solving everyday problems. This study aims to analyze the mathematical literacy ability of students at grade XI of SMAN 1 Kediri. The research method used was descriptive qualitative. The research subjects consisted of 6 students from 26 total students in 1 class. This study pays attention to the student's initial mathematical ability (IMA) factor. Based on the results of the study, 19% students who had high IMA could solve routine problems, interpret problems and solve them with formulas, carried out procedures well, we're able to overcome complex situations and used reasoning in problem-solving, and they were able to work effectively and interpreted representations that were different then connected it to the real world (Level 4). Students who had medium IMA (66%) were able to solve routine problems, interpreted problems and solved them with formulas, and carried out procedures well (Level 3). While students who had low IMA (15%) were only able to solve routine problems (level 1).

Abstract

 This research aims to describe the use of the problem based learning model in improving students' critical thinking disposition in mathematics in class XI at SMAN 1 Lingsar. The type of research used by researchers is Classroom Action Research (PTK) which has four stages, namely planning, implementation, observation and reflection. The subjects of this research are students in class XI IPA 3, totaling 35 students, consisting of 20 male students and 15 female students. . This research instrument uses evaluation sheets and observation sheets of teacher and student activities. The data collection technique in this research is by providing evaluation tests and classroom observations. The research results showed that the average student critical thinking disposition test results in cycle I was 76.90 and the average in cycle II was 78.6. Meanwhile, the percentage of classical completeness achieved in cycle I was 57.14% and the percentage of classical completeness in cycle II was 60%. From the detailed data for each cycle, it can be concluded that the critical thinking disposition with the application of the PBL model experienced a slight and significant increase.

Abstract

The industrial revolution 4.0 and the rapid advancement of technology during pandemic era has made significant progress in robot industry. There are three types of robots based on the level of independent control such as autonomous mobile robots, semi-autonomous mobile robots, and controller mobile robots. Semi-autonomous mobile robot and Controlled mobile still require human intervention in carrying out the tasks. In this study, teleoperation on mobile robots is displayed on various platforms such as Smartphone, Virtual reality headset as a virtual reality platform, and Computer (SVC) device. A camera is used as a visual sensor that dispatches the information of the surroundings to each platform. The controller used for the teleoperation varies depending on the platforms. The computer platform uses the arrow key on the keyboard. The smartphone platform uses touchscreen. Virtual reality uses Oculus Touch that has been integrated with Oculus Quest 2. ROS# as a robot API framework with Unity engine is used for the communication process between the robot and each platform. Teleoperation Experiments on SVC devices refer to four parameters including task completion rates, task time, satisfaction, and error counts. all these parameters will be combined into a single usability metric (SUM). The SUM results from SVC devices show 54.9% on Smartphones, 79.5% on VR devices, and 90.4% on Computers.
