Permainan tenis meja atau yang lebih dikenal dengan istilah “pingpong” merupakan suatu cabang olahraga yang unik dan kreatif. Kemajuan teknologi telah memunculkan robot pelontar bola tenis meja yang membantu dalam proses latihan permainan tersebut. Penelitian ini bertujuan membuat sistem antarmuka robot pelatih tenis meja yang lebih murah, lebih menarik dari sisi tampilan user interface serta menggunakan apikasi desktop berbasis Borland Delphi yang terkoneksi kabel USB. Hasil uji coba robot pelatih tenis meja menunjukan bahwa robot dapat dikendalikan melalui aplikasi dengan jarak maksimal koneksi sejauh 20 meter. Untuk menghasilkan lontaran bola servis parameter robot pelatih tenis meja yaitu dengan mengatur kecepatan pelontar atas dan bawah sebesar 30% kecepatan PWM dengan sudut atas bawah (-30° sampai + 30°), sudut kanan kiri (-30°) sampai (+30°) sedangkan kecepatan ball feeder berkisar antara 70% - 100%. Dengan menggunakan metode System Usability Score penilaian tampilan aplikasi robot pelatih tenis meja mendapat skor 64,5 pada Acceptability range marjinal high, Adjective rating mendapatkan rating OK, dan Grade scale mendapat nilai D.

Pada era modern saat ini, pemanfaatan Internet of Things (IoT) sudah sangat banyak diterapkan di berbagai lini kehidupan, hampir dari semua perangkat elektronik sudah tersambung ke internet. Seiring dengan berkembangnya teknologi, pengaplikasian teknologi di sektor pertanian sangat perlu diperhatikan. Dikarenakan kebutuhan akan pengamatan dan pemeliharaan tanaman semakin meningkat. Oleh karena itu, pentingnya pemeliharaan serta pengamatan tanaman agar tanaman yang ditanam dapat menghasilkan mutu yang baik. Pada penelitian ini, dirancang sebuah program penyiraman tanaman dan pengamatan tanaman otomatis yang terhubung ke jaringan internet sehingga para penggunanya dapat merawat dan memantau tanaman agar terjaga dan menghasilkan kualitas tanaman yang bermutu. Sistem ini dirancang menggunakan mikrokontroler NodeMCU ESP8266 sebagai pusat kontrol sistem. Pada penelitian ini telah berhasil dirancang suatu program pemantauan serta penyiraman tanaman secara otomatis dengan membaca kadar kelembaban yang ada di dalam tanah. Hasilnya adalah program ini dapat memberikan kebutuhan air yang tepat untuk tanaman. Kemudian program mengirimkan informasi ke halaman website yang telah dibangun agar pengguna dapat memonitor tanamannya.
The progress of the library automation system (Library Management System) in the library has now been carried out, especially during a pandemic that requires maintaining distance and face-to-face contact. Starting from that thought, the UNISMA community service team is interested in holding library NGO (Library Management System) training activities Web-based BJ School. This BJ Scholl library website serves to present various information on books, journals and magazines, history and school vision and mission, member data, online book lending and book return data. Apart from the web, it also displays a link feature with several online libraries from several agencies. The training was carried out offline for 1 day and continued with online discussions. The training begins with the introduction of several topics about the website, followed by downloading and installation. Prior to the training, 100% of the participants had never created a website, either with wordpress or with other applications. And after the training, 60% of the participants have been able to apply website creation for their library. Some of the participants were constrained by a slow network and computer damage, so they were late in following the material given. All participants stated that this training was very useful.
