Abstract

This research is motivated by the condition of children with autism who require continuous monitoring without a parent accompany, and certain therapies who is capable to reduce repetitive behaviors and increase the concentration. Music therapy is one of the treatment which able to perform it. The implementation of this research is located in a special schools with autism, the perform is proper at certain times and requires tools for music therapy. Therefore, the integrated device was made to monitor the activities of children with autism, as well as providing music therapy automatic face recognition based on Eigenface method.This device perform when the children with autism under certain conditions (e.g. crying, the teacher would not work orders, etc.), then by capturing the the facial image, the system will process to compare the similarity with the existing database. Then, the shortest distance of euclidean is chosen. If the captured of facial image is similar to the one existing database, then the music is performed as music therapy for children with autism. The results of this system, indicates that the childs responses become more calm, easy concentration, and the repetitive attitude is reduced. While the accuracy of the system achieves by 80% (compare with the old and new database) and 20%. (without new database). ©2017 JNSMR UIN Walisongo. All rights reserved.

Abstract

Telah dilakukan perancangan, dan implementasi sistem pengendali motor servo dalam FPGA FLEX-10Kmenggunakan VHDL. Sistem terbagi atas 2 macam, yang masing-masing dibatasi dengan ruang putar servo 0-180 derajat.Sistem pertama dirancang secara keseluruhan menggunakan deskripsi VHDL dengan pengontrol 2 tombol-tekan danpenampil sudutnya 3x7-segment. Sistem kedua merupakan kombinasi antara modul driver yang ditulis dalam deskripsiVHDL, dan bagian antarmuka yang dituliskan dalam Delphi 7.0. Sumber daya yang dibutuhkan pada sistem pengendali yangpertama adalah 277 elemen logika dan 63 flip-flop dengan waktu rambat sebesar 12.5 nd. Sedangkan yang keduamembutuhkan 140 elemen logika, dan 33 flip-flop dengan waktu rambatnya 12.4 nd.

Abstract

Safe is a tool used to store goods or assets and securities. Generally, a safe uses an analog lock made of metal and a rotary combination lock as a security system. However, the existing safe is not equipped with an information system that will notify the owner when the safe is accessed. This research was developed a safe security system using a digital key in e-KTP form which is detected by RFID (Radio Frequency Identification) sensor and the system was equipped with an information system based on nodeMCU ESP8266 to send notifications. The system designed consists of RC522 RFID module used to detect the e-KTP ID of the safe accesser. RFID connected to the nodeMCU platform which is an IoT device and connected to the cloud via wifi ESP8266. The information contained in the cloud from the IoT device and forwarded to the receiving smartphone as notification.

Abstract

Budidaya ikan air tawar dengan sistem bioflok telah menjadi solusi inovatif dalam meningkatkan produktivitas serta efisiensi penggunaan air dan pakan. Namun, tantangan utama dalam sistem ini adalah menjaga kualitas air tetap optimal secara berkelanjutan. Penelitian ini mengembangkan sistem kendali kualitas air berbasis logika Fuzzy Sugeno yang diimplementasikan pada mikrokontroler ESP32 dual-core untuk mengotomatisasi pemantauan dan pengendalian parameter suhu, pH, serta kekeruhan air secara real-time. Penggunaan ESP32 memungkinkan pengolahan data yang lebih cepat dan efisien berkat fitur dual-core yang mendukung pemrosesan sensor dan aktuator secara simultan.Hasil pengujian menunjukkan bahwa metode Fuzzy Sugeno mampu memberikan respons kendali yang lebih presisi dibandingkan dengan sistem manual. Meskipun sistem kendali telah bekerja sesuai rancangan, sensor amonia yang dibuat menggunakan kombinasi sensor warna TCS3200 dan kertas uji amonia masih memerlukan pengembangan lebih lanjut karena belum mampu mendeteksi amonia secara aktual. Dengan peningkatan ini, sistem diharapkan dapat menjadi solusi efektif dalam otomatisasi pemeliharaan kualitas air kolam dan meningkatkan keberlanjutan produksi akuakultur.
