The research method used is the method of causality (cause and effect) in which the questionnaire is the research instrument. The sampling technique is using purposive sampling with a sample of 140 students. This study uses data analysis techniques, namely using t test using a linear regression model. The results of the analysis there are 2 models which can be seen in model I the significance value of the variable (X1) is 0.257, it can be said that this variable has no effect on (Z) because it is greater than 0.05, the variable (X2) is less than 0.001 it can be said that the variable this has an effect on (Z) because it is smaller than 0.05, and the variable (X3) is worth less than 0.001 it can be said that this variable has an influence on (Z) because it is smaller than 0.05, In model II it can be seen the significance value on the variable (Z) is less than 0.001 it can be said that this variable has an influence on (Y) because it is smaller than 0.05. This shows that in model I, in terms of usability and service quality, it can affect the desire to use LMS, while in terms of convenience it has no effect on the use of LMS, and for model II, it can be said that the desire to use LMS significantly affects learning effectiveness.</em></p> Engelbertus William Archian Nuhuyanan, Sri Wahyu Widyaningsih, Kaleb A.

This PCR method is implemented as Thermal Cycler or PCR machine. One of the main components in the Thermal Cycler is the heater. Three heaters, such as: Peltier Device 12715, Ceramic Heater PTC 12 V<sub>DC</sub>, and Customized Heater 12 V<sub>DC</sub> were tested for their performance by being connected to 3-well aluminium block. Two pieces of PTC Ceramic Heaters 12 V<sub>DC</sub> with a total power of 120 W showed the best performance compared to the other 2 heaters and were able to provide a heating ramp rate of 0,13 /second.</em></p> Nugroho Budi Wicaksono, Sukma Meganova Effendi, Agatha Mahardika Anugrayuning Jiwatami ##submission.copyrightStatement## Fri, 02 Jun 2023 00:00:00 +0000 Studi Awal Teknik Perekaman Citra pada Perangkat Medis untuk Efisiensi Distribusi Citra Medis <p><em>Medical imaging is one method that is widely used to provide information about the physical parts of the body for diagnosis and therapy. This research is an initial study to find appropriate technology to record medical imaging results in the form of photos and videos so that they are ready to be distributed to support the telemedicine process. This research was conducted by studying literature on the equipment that might be used for the screen capture process, followed by making a prototype of the tool to be used as FGD material. During the FGD process, discussions were held with radiology specialists and gynecologists, nurses and technicians to find out the impact of this tool. The results show that it is possible to distribute medical images using screen capture techniques. This research is the first step for the development of medical image distribution.</em></p> Bernardinus Sri Widodo, Agatha Mahardika Anugrayuning Jiwatami ##submission.copyrightStatement## Fri, 02 Jun 2023 00:00:00 +0000 Reka Cıpta Mesın Sortır Warna Benda Menggunakan Kamera PIXY2 CMUCAM5 <p><em>Learning instrument is an important things in the learning process.</em> <em>Mechatronics systems that have complex circuits and controllers are not easily understood by Level 1 and 2 Students. This research applies the R&amp;D method of Sugiyono &nbsp;to produce sorting machines that are easy to use and learn. The Pixy2 CMUcam5 camera is used for color detection. The controller circuit are used is Karnaugh Map circuit using Digital IC (NOT-AND-OR) and Arduino Uno. The color combinations processed in Karnaugh Map controller circuit are sorting 1 color (Red-R/ Green-G/ Blue-B), 2 colors (R&amp;G/ R&amp;B/ G&amp;B), and 3 colors (R&amp;G&amp;B). Results of this sorting machine are can be operated easily, reprogrammed for both object color detection and DC motor &amp; servo motor control, and rebuilt for the Karnaugh Map series. Validation of this study resulted in improvements to the initial turntable design which was improved with a timing belt mechanism to stabilize the turntable rotation. Lighting of indoor/outdoor does not affect the system because the Pixy2 has an internal LED so that the color is detected properly. The results of sorting with the final turntable design have good performance with an average success of 97.96% and a standard error of 0.58.</em></p> Sukma Meganova Effendi, Agatha Mahardika Anugrayuning Jiwatami, Nugroho Budi Wicaksono ##submission.copyrightStatement## Fri, 02 Jun 2023 00:00:00 +0000 Rancang Bangun Alat Parut Modifikasi Sebagai Teknologi Tepat Guna <p><em>Coconut meat is one type of raw material that is most often used in the small food catering industry, where coconut processing is done by grating it. The process of grating coconut is sufficient to be done manually with a simple grater board if there are only a few, to produce a good grater, the speed of a manual grater requires approximately 3000 grating movements every hour. A coconut grater is a tool product for household needs that functions as a tool to crush coconuts into small granules, with the aim of obtaining the coconut milk contained in the coconut flesh. This study aims to design an appropriate technology in the form of a more ergonomic mid-scale modified coconut grater. From the test results obtained, the higher the rotational speed of the cylinder or the cutting speed of the grating knife, the higher the grating capacity. This is because the faster the cutting speed of the grating knife, the faster the cycle or frequency of grating.</em></p> Ovilia putri utami gumay, Reno Ali Afan ##submission.copyrightStatement## Fri, 02 Jun 2023 00:00:00 +0000 Desain Physics Brain: Aplikasi Pembelajaran Kinematika Gerak untuk Meningkatkan Kemampuan Berpikir Kritis Dan Literasi Sains Siswa SMA <p><em>This study aims to determine the feasibility of the Physics Brain application as an android-based learning media to improve critical thinking and scientific literacy skill in the developed physics lesson.

If students have good metacognitive, it will be more effective to select and find important information to solve problems than students who don’t have metacognitive. Swartz and Perkins divide the metacognitive level into 4 parts, namely tacit use, aware use, strategic use, and reflective use. This study aims to describe the metacognitive levels of students who have high, medium and low abilities in solving problems in the Law of Thermodynamics material. This research was conducted at SMA Negeri 1 Tambang with 23 students from class XI MIPA 2 as research subjects. This research was included in a descriptive study. The written test is a data collection method used in this study. The results of the test will be used to analyze students' metacognitive abilities. The results of this study are students who have learning outcomes in high groups are at the level of metacognitive Reflective Use. Students who have learning outcomes in groups are at the Strategic Use metacognitive level. Students who have low group learning outcomes are at the Tacid Use metacognitive level.</em></p> Catharine Miranda, Muhammad Nasir, M.

The research area is the Bengkulu Province region which is in position a using in-depth zonal current data, in-depth temperature data and salinity data. To see the distribution map, this data is then processed using GrADS (The Grid Analysis and Display System) software. The analysis used in this study is the Hӧvmuller diagram analysis. Based on the results of the study during a positive IOD it was seen that there was a movement of deep zonal currents. These zonal currents carry low-temperature water masses from the deep layers to the surface layers. Prior to the occurrence of a positive IOD, the salinity value in Bengkulu Province waters varied between . When a positive IOD occurs, the salinity value in Bengkulu Province waters rises to and is almost uniform.</p> Septi Johan, Supiyati Supiyati, Suwarsono Suwarsono ##submission.copyrightStatement## Fri, 02 Jun 2023 00:00:00 +0000 Pengembangan Medıa Pembelajaran Interaktıf Power Poınt Berbasıs Problem Based Learnıng Pada Materı Suhu Dan Kalor <p><em>This research aims to develop problem-based learning-based interactive learning media on temperature and heat materials for eleventh grade students.
