Abstract

Saat ini, kegiatan belajar mengajar di berbagai universitas di Indonesia umumnya dilakukan menggunakan laptop yang terhubung ke sebuah proyektor. Di dalam proses pengajaran, dosen cenderung menggunakan laptop di ruang kelas, menghubungkan tampilan layar laptop ke sebuah proyektor, kemudian menggunakan wireless pointer sebagai pengendali slide presentasi. Pendekatan semacam ini sayangnya tergolong kurang efektif di dalam perkuliahan berbasis Student Centered Learning (SCL). Di dalam SCL, mahasiswa merupakan pusat kegiatan perkuliahan, dimana keterlibatan dan interaksi mahasiswa di dalam proses penyampaian materi merupakan hal terpenting guna meningkatkan animo dan pemahaman mahasiswa mempelajari suatu topik. Penggunaan teknologi perkuliahan konvensional seperti laptop dan wireless pointer cenderung membuat perkuliahan menjadi 1 arah karena interaksi mahasiswa kurang dapat tersalurkan. Di dalam penelitian ini, dilakukan analisis dampak penggunaan teknologi informasi sensor kamera 3 dimensi Kinect sebagai media pembelajaran dalam suatu sistem Smart Classroom. Kinect merupakan sensor yang dapat menangkap gerakan tangan seseorang kemudian menginterpretasikan gerakan tersebut sebagai suatu perintah komputasi berdasarkan algoritma pemrograman tertentu. Berdasarkan hasil penelitian, penggunaan Kinect terbukti dapat meningkatkan efektivitas pembelajaran SCL dan antusiasme belajar mahasiswa karena mahasiswa dapat berinteraksi di dalam suatu materi perkuliahan secara lebih alami menggunakan gerakan tangan.

Abstract

Lombok merupakan salah satu tujuan wisata utama yang ada di Indonesia, keindahan alamnya tidak kalah dengan Bali yang sudah terlebih dahulu terkenal di Manca Negara. Keberagaman budaya dan produk lokal yang dimiliki juga sangat banyak dan mendukung peningkatan jumlah kunjungan wisata. Promosi yang dilakukan oleh pemerintah tidak dapat mengakomodir semua obyek wisata dan mempromosikan produk lokal dari masyarakat tersebut, karena seiring dengan kesadaran masyarakat tentang pentingnya pariwisata dalam meningkatkan kesejahteraan, banyak sekali muncul obyek wisata baru dan produk- produk baru yang tidak tersentuh oleh promosi pemerintah. Dan promosi yang dilakukan secara konvensional membutuhkan biaya yang sangat mahal. Diera digital saat ini media sosial, memegang peranan sangat penting dalam mempromosikan sesuatu. Selain kemampuannya untuk mempromosikan produk ataupun obyek, media sosial juga bisa digunakan untuk membuat personal branding yang pada hilirnya dapat mendatangkan keuntungan materi. Untuk membuat konten yang menarik perlu pelatihan ketrampilan kepada masyarakat untuk dapat meningkatkan kemampuannya dalam membuat konten yang ditampilkan dalam media sosial sehingga lebih banyak orang melihat dan berkomentar yang pada akhirnya dapat menjadi media promosi yang murah

Abstract

Currently, almost all banks have used mobile banking in conducting banking transactions, one of which is Bank Syariah Indonesia (BSI). BSI mobile is still classified as a new mobile banking application compared to other mobile banking, this certainly still has a low rating and really needs feedback from users which can be seen through reviews on the Google Play Store application. Input in the form of criticism and suggestions from BSI mobile users can be used by BSI mobile as a suggestion for careful supervision and evaluation material in improving its services. This study aims to find the best algorithm to analyze review sentiment on the Google Play Store for the BSI mobile application and provide an overview of the response of application users to application developers based on the results of review data processing. The data mining methodology used in this study is CRISP-DM, using a dataset collected for 6 years (2018-2023) which is annotated into positive and negative labels manually, then modeled using 2 algorithms, namely Naïve Bayes (NB) and Bidirectional LSTM (BiLSTM). The contribution of this study is to test, evaluate and compare the two algorithms (NB and BiLSTM) using the K-Fold Cross Validation (NB) testing model and over-sampling techniques to the minority class (negative) then provide recommendations for the best algorithm. The conclusion of the study is that the BiLSTM algorithm is superior to NB with an accuracy of 94.90 % while the NB algorithm is 94%. In addition, the over-sampling technique is more optimal in increasing the accuracy of the algorithm's performance compared to without over-sampling.

Abstract

We developed a virtual reality (VR) simulation of a chemistry practicum that incorporates the act of pouring liquid using hand gestures. This addresses the need for safe, cost-effective alternatives in chemistry education while still exercising practicum motor skills. Our simulation centers on the practicum of making picric acid, which presents significant both cost and safety challenges. Utilizing Leap Motion hand gesture technology as an input method offers a more affordable option than traditional VR controllers. We conducted usability testing with 16 participants, including a lecturer and undergraduate students from multiple backgrounds, to evaluate the application’s effectiveness and gather feedback. Results indicate that the simulation works as intended and accurately represents the practicum, achieving marginal usability. The application can reduce costs by at least IDR 658,638.00 per session and eliminates hazards associated with handling picric acid, highlighting its potential as a valuable educational tool.
