Abstract

ABSTRAKKomunikasi cahaya tampak (Visible Light Communication) merupakan solusi untuk komunikasi berkecepatan tinggi pada sistem berbasis Internet of Things. Model pintu otomatis berbasis IoT menggunakan komunikasi cahaya tampak berhasil dibuat untuk keamanan rumah. Komunikasi tersebut dengan panjang gelombang 650 nm berwarna merah diujicobakan untuk jarak 20 cm. Penerima fotodioda mengaktifkan motor servo untuk membuka pintu dengan maksimal sudut rotasi 120 derajat. Ada enam macam kondisi pintu terbuka yang ditampilkan di LCD dan dikirimkan melalui internet ke website. Secara keseluruhan sistem berjalan dengan baik. Komunikasi cahaya tampak juga diujicobakan sebagai sinyal pembawa dengan mendeteksi tegangan yang dikirimkan oleh laser di fotodioda. Berdasarkan ujicoba didapatkan data yang dikirimkan dapat diterima dengan baik, walaupun perubahan tegangan turun sampai dengan 1.5% di fotodioda.Kata kunci: komunikasi cahaya tampak (Visible Light Communication), Internet of Things, pintu otomatis, keamanan, sinyal pembawa ABSTRACTVisible Light Communication (VLC) is a solution for high-speed communication that can be utilized for Internet of Things (IoT) systems. An automatic door model based on IoT using VLC has been successfully assembled for user security at home. This communication, with a wavelength of 650 nm in red light, was tested for 20 cm. The photodiode receiver activates the servo motor to open the door with a maximum rotation angle of 120 degrees. The open door process consists of 6 different conditions displayed on the LCD and transmitted via the internet to the website. In a comprehensive evaluation, the system operates optimally. In addition, VLC was also tested as a carrier signal to examine the voltage sent by the laser. Based on the experiment, the data sent can still be received well, even though there is a voltage change up to 1.5% at the photodiode receiver.Keywords: Visible Light Communications (VLC), Internet of Things, automatic door, security, carrier signal

Abstract

The results of the analysis test can be used as a means to know the students' learning difficulties and as a guide to know how to overcome such difficulties. The purpose of this study is to identify and know the causes of learning difficulties on accounting worksheet materials. In analyzing the data presented the difficulty of learning accounting work sheet material based on the cognitive domain. The results showed that students had difficulty working on the worksheet on the dimensions of remembering i.e : "Writing corporate identity and period of worksheet", Categorization and account coding", and on the dimensions of understanding i.e : "Write the code of the newly opened account", and on the dimensions of applying i.e : "Lacking careful when posting post balance and adjusting journal", "Preparation of balance sheet after adjusted", and on analyzing dimensions: "Specifying real account and nominal account", and on evaluating dimensions i.e : "Determine the profit/loss company," and on the dimensions of creating difficulties caused by difficulties in other dimensions, while the way to overcome learning difficulties accounting worksheet material learning is to continue to practice in working worksheet and often ask to friends and teachers if there is a not understood.

Abstract

Komunikasi verbal adalah komunikasi umum digunakan sebagai sarana dalam memberikan informasi kepada orang lain. Disamping itu, untuk berkomunikasi dengan tuna rungu serta tuna wicara sarana komunikasi dapat melalui bahasa isyarat. Indonesia telah memiliki sistem bahasa isyarat yaitu Bahasa Isyarat Indonesia atau Sistim Isyarat Bahasa Indonesia (SIBI). Aplikasi pengenalan dan pembelajaran SIBI yang ada pada saat ini berupa aplikasi yang terikat pada platform. Aplikasi beserta proses pengenalan menjadi satu sehingga memiliki kebergantungan yang cukup tinggi. Penelitian ini bertujuan mengembangkan platform cloud sebagai backend untuk pengenalan gerakan tangan, sehingga memudahkan pengembang untuk membuat aplikasi pengenalan SIBI. Platform tersebut memiliki kemampuan untuk mengenal gerakan tangan yang diperoleh dari data sensor Myo Armband. Aplikasi yang berada sisi frontend dapat menggunakan fitur platform melalui Application Programming Interface (API) yang disediakan. Penelitian ini juga membangun aplikasi permainan edukasi yang menggunakan platform cloud tersebut sebagai implementasi dari penggunaan platform. Hasil pengujian terhadap platform yang dilakukan menghasilkan kemampuan pengenalan secara real-time dari satu atau lebih client secara simultan. Pada uji 5 client request bersamaan secara simultan, waktu yang dibutuhkan rerata 0.1107333 detik per request pada latency jaringan rerata 36.7 ms.   AbstractVerbal communication is a general communication used in providing information to other people. On the other hand, to communicate with deaf and speech impaired people can use sign language. Indonesia has a sign language system called Indonesian Sign Language or Indonesian Sign Language System (SIBI). The current SIBI introduction and learning application is an application tied to the platform. Application, along with the recognition process, is combined so that it has a high enough dependence. This study aims to develop a cloud platform as a backend for hand gesture recognition, making it easier for developers to create SIBI recognition applications. The platform can recognize hand movements obtained from Myo Armband sensor data. Applications on the front-end side can use the platform features through the provided Application Programming Interface (API). This study also builds an educational game application that uses the cloud platform to implement platform usage. The results of the platform's testing carried out resulted in real-time recognition capabilities from one or more clients simultaneously. In the five simultaneous client requests test, the average time needed is 0.12654 seconds per request at a mean network latency of 36.7 ms.
