Banyak penelitian yang mengungkapkan bahwa penggunaan ICT memberikan warna baru dalam interaksi proses pembelajaran. Namun, masih banyak kendala yang dihadapi ketika mengintegrasikan teknologi dalam proses pembelajaran khususnya pembelajaran matematika. Oleh sebab itu, tujuan penelitian ini menyoroti kelayakan dari mobile learning berbantuan Appy Pie pada pembelajaran matematika di masa pandemi Covid 19. Untuk mencapai tujuan tersebut penelitian ini menggunakan desain pengembangan ADDIE yang terdiri dari tahapan-tahapan analisis, pendesainan, pengembangan, implementasi, evaluasi. Pada penelitian ini tahap evaluasi tidak dilakukan karena keterbatasan waktu pelaksanaan. Tahap analisis yang dilakukan yakni analisis masalah dan kebutuhan, analisis ruang lingkup materi, analisis proses integrasi dan pengumpulan bahan pendukung. Selanjutnya untuk tahap pendesainan melakukan proses penyusun desain instruksional, menyusun alur kerja dan alur cerita dan menyiapkan aset-aset elemen pembuatan produk. Tahap pengembangan yakni menghasilkan aplikasi berbantuan Appy Pie materi geometri bangun ruang. Tahap implementasi melakukan proses pengujian internal, penilaian ke ahli media dan ahli materi, uji lapangan. Berdasarkan hasil temuan diperoleh bahwa aplikasi mobile learning terintegrasi Appy Pie layak digunakan untuk pembelajaran geometri di kelas VIII SMP. Oleh karena itu, aplikasi mobile learning terintegrasi Appy Pie memiliki potensi meningkatkan pemahaman geometri siswa sekolah.

Geometry Learning

The purpose of this study is to design geometry learning media for early childhood. The tool designed is an interactive introduction tool, so it is hoped can attract early childhood children to learn to recognize and remember geometric patterns. The main brain of the system created is Arduino Mega with microcontroller ATMega2560. The tool created has two modes, namely learning mode and question mode. In learning mode, early childhood can insert geometry objects into the tool, then the tool will provide a description of the image on the LCD and the sound associated with the object entered. In question mode, early childhood will be challenged to enter the geometry objects into the tool according to the question, then the tool will determine whether the geometry entered is correct or false. This learning media is expected to help early childhood to be able to recognize and remember every form of geometry, where based on the results of the test, the selection mode on the tool was 100% successful, the process in the learning mode and the question mode had a success rate of more than 80%.

Abstract The acoustic-based automatic speech recognition (ASR) technique has been a matured technique and widely seen to be used in numerous applications. However, acoustic-based ASR will not maintain a standard performance for the disabled group with an abnormal face, that is atypical eye or mouth geometrical characteristics. For governing this problem, this article develops a three-dimensional (3D) sensor lip image based pronunciation recognition system where the 3D sensor is efficiently used to acquire the action variations of the lip shapes of the pronunciation action from a speaker. In this work, two different types of 3D lip features for pronunciation recognition are presented, 3D-(x, y, z) coordinate lip feature and 3D geometry lip feature parameters. For the 3D-(x, y, z) coordinate lip feature design, 18 location points, each of which has 3D-sized coordinates, around the outer and inner lips are properly defined. In the design of 3D geometry lip features, eight types of features considering the geometrical space characteristics of the inner lip are developed. In addition, feature fusion to combine both 3D-(x, y, z) coordinate and 3D geometry lip features is further considered. The presented 3D sensor lip image based feature evaluated the performance and effectiveness using the principal component analysis based classification calculation approach. Experimental results on pronunciation recognition of two different datasets, Mandarin syllables and Mandarin phrases, demonstrate the competitive performance of the presented 3D sensor lip image based pronunciation recognition system.

The focus of this research is to design geometry learning mediain junior high schools based on RME and integrated with Science, Technology, Engineering and Mathematics (STEM) using 3D Pageflip Proffesional,and to explain quality of the learning media. In the process of design and development of this media used is the ADDIE development model which begins with the stages analysis, design, development, and  carried out an evaluation in each stages. Implementation stages will be continued in the following years research. This research resulted in a product in the form of geometry learning media in junior high schools especially eight grade according to purpose. Based on the validity test and practicality test the results obtained from the validation by material experts and media design experts were 4.09 namely 81.8% and 4.21 or 84.2%.Based on the criteria for the validity of the instrument, the criteria for "very valid" were obtained. And the practicality results, namely the results of teacher response questionnaire obtained an average of 4.26 or 85.19%, and the results of student questionnaire responses were 4.07 or 81.4%. Then based on the percentage criteria of practicality of the instrument, it is found that the criteria are very practical and the media can be implemented with minor revisions.

Artificial Teeth

The creation of acrylic dentures involves many stages. One of them is to prepare the surfaces of artificial teeth for connection with the denture plates. The teeth could be rubbed with a chemical reagent, the surface could be developed, or retention hooks could be created. Preparation of the surface is used to improve the bond between the teeth and the plate. Choosing the right combination affects the length of denture use. This work focuses on a numerical analysis of grooving. The purpose of this article is to select the shape and size of the grooves that would most affect the quality of the bond strength. Two types of grooves in different dimensional configurations were analyzed. The variables were groove depth and width, and the distance between the grooves. Finally, 24 configurations were obtained. Models were analyzed in terms of their angular position to the loading force. Finite element method (FEM) analysis was performed on the 3D geometry created, which consisted of two polymer bodies under the shear process. The smallest values of the stresses and strains were characterized by a sample with parallel grooves with the grooving dimensions width 0.20 mm, thickness 0.10 mm, and distance between the grooves 5.00 mm, placed at an angle of 90°. The best dimensions from the parallel (III) and cross (#) grooves were compared experimentally. Specimens with grooving III were not damaged in the shear test. The research shows that the shape of the groove affects the distribution of stresses and strains. Combining the selected method with an adequately selected chemical reagent can significantly increase the strength of the connection.
