Abstract

Sound signals polluted by noise are a common problem in various audio applications, including communication, sound processing, and audio recording. In this article, proposes the use of Kalman Filter algorithm as an effective method to reduce noise in speech signals. Simulations are performed using Matlab software to implement the Kalman Filter algorithm on noise polluted voice signals. The study includes several important steps, including the input of noise-polluted speech signals and the implementation of the Kalman Filter to clean the signals. Simulation results are measured using commonly used audio quality metrics, such as Signal-to-Noise Ratio (SNR) and Mean Square Error (MSE), to evaluate the effectiveness of the algorithm. The results from the simulations show that the use of the Kalman Filter algorithm significantly improves the quality of noise-contaminated speech signals. These results indicate that this algorithm can be a potential solution to the problem of noise reduction in audio applications. In addition, the implementation in the Matlab environment allows for easy testing and adaptation of this algorithm for different types of audio applications. This research makes a positive contribution to the development of more efficient noise reduction techniques in speech signal processing, focusing on the use of the Kalman Filter algorithm and its implementation using Matlab software. The implications of this research can be potentially beneficial in improving the quality of sound signals in various audio application contexts.

Abstract

The presence of wild monkeys in the Engineering Prayer Room at Malikussaleh University has become a severe problem for cleanliness and worship activities. Monkeys often damage equipment and disturb the comfort of pilgrims, causing material losses and threatening environmental cleanliness. Traditional methods to repel monkeys have proven ineffective for a long time, so technological solutions such as ultrasonic waves are needed. This study looked at the effects of using various ultrasonic frequencies on monkeys at multiple distances to determine their effective range of distraction. The results show higher frequencies cause more significant interference, especially at close range. At 23 kHz and 26 kHz, monkeys were only disturbed at a distance of 1 and 2 meters, without disturbance at 3 and 4 meters. The frequencies 29 kHz and 32 kHz show interference at a distance of 1 and 2 meters, with variations at 29 kHz at 3 meters. At 35 kHz, the monkeys were highly disturbed at 1 meter, disturbed at 2 meters, and slightly disturbed at 3 and 4 meters. The 38 kHz and 41 kHz frequencies cause significant interference at 1 and 2 meters, and interference is still felt at 3 and 4 meters. Thus, using frequencies above 30 kHz has proven effective in driving away monkeys up to a distance of 4 meters, with the highest intensity of interference at a distance of 1 to 2 meters. It is hoped that using ultrasonic technology can maintain cleanliness, safety, and comfort in prayer activities in prayer rooms and demonstrate commitment to sustainable and environmentally friendly solutions.

Abstract

Program pengabdian kepada masyarakat ini bertujuan untuk memberikan pendampingan teknis dan manajerial kepada siswa dan guru Madrasah Aliyah Negeri (MAN) Kota Lhokseumawe dalam mempersiapkan partisipasi mereka di ajang Madrasah Robot Competition (MRC). Latar belakang kegiatan ini adalah keterbatasan pengetahuan dan pengalaman dalam penyusunan proposal yang sesuai dengan standar kompetisi, serta kurangnya keterampilan teknis dalam pengembangan robot yang kompetitif di tingkat nasional. Untuk itu, program ini dirancang untuk memberikan bimbingan secara komprehensif mulai dari pelatihan penyusunan proposal, pemahaman dasar robotika, perancangan dan pemrograman robot, hingga pengujian kinerja robot. Pelaksanaan program dilakukan melalui beberapa tahap, yaitu identifikasi kebutuhan, pelatihan penyusunan proposal, workshop teknis perancangan robot, dan simulasi uji coba robot. Hasil yang diperoleh menunjukkan peningkatan yang signifikan dalam kemampuan siswa dan guru dalam menyusun proposal yang lebih inovatif dan terstruktur, serta merancang robot yang sesuai dengan spesifikasi kompetisi. Selain itu, program ini juga berhasil memperkuat kapasitas guru dalam mendampingi siswa, sehingga mereka dapat berperan sebagai mentor yang efektif dalam pengembangan proyek-proyek robotika di masa depan. Tindak lanjut yang dirancang dari program ini mencakup pembentukan tim robotika sekolah yang berkelanjutan, pengembangan kerjasama dengan universitas dan komunitas robotika, serta peningkatan fasilitas sekolah seperti pengadaan laboratorium robotika. Selain itu, siswa juga didorong untuk mengembangkan proyek-proyek robotika berbasis solusi permasalahan lokal, yang dapat bermanfaat bagi masyarakat sekitar. Dengan adanya tindak lanjut ini, diharapkan MAN Kota Lhokseumawe dapat terus mengembangkan program robotika secara mandiri dan mampu bersaing di berbagai kompetisi robotika di masa mendatang, sekaligus memperkuat kualitas pendidikan berbasis teknologi di lingkungan sekolah.

Abstract

Indonesia memiliki populasi penduduk yang padat dan tinggi, menyebabkan kepadatan lalu lintas yang tinggi dan meningkatkan risiko kecelakaan. Kurangnya kendali dan kontrol terhadap sistem pengereman kendaraan roda dua dapat menyebabkan kecelakaan serius. Untuk mengatasi masalah ini, penelitian ini bertujuan untuk merancang dan membangun alat perekam waktu rem dan benturan pada kendaraan roda dua. Alat ini menggunakan sensor kecepatan LM393, GPS, GY-521, dan ACS712 untuk merekam data kecepatan, posisi geografis, dan kejadian tabrakan atau pengereman pada kendaraan. Dari hasil pengujian, sensor GPS menunjukkan galat antara nilai yang diberikan oleh sensor GPS dan Google Maps berkisar antara 0.0000103% hingga 0.0092% untuk Lattitude, dan 0.0010% hingga 0.0396% untuk Longitude. Sensor accelerometer GY-521 mengukur akselerasi laju perubahan kecepatan suatu objek . Sensor LM393 memiliki jumlah galat sebesar 17,20% dengan nilai rata-rata galat sebesar 1,72%. Modul SD Card menunjukkan kinerja yang baik dalam menyimpan data, dengan hasil pengujian menunjukkan bahwa modul dapat diandalkan dan kompatibel dengan berbagai jenis kartu memori. Hasil pengujian simulasi tabrakan menunjukkan bahwa alat perekam berhasil mendeteksi kejadian tabrakan dengan akurat, dan hasil pengujian simulasi jatuh sendiri juga mengindikasikan bahwa alat perekam dapat merekam kejadian tersebut dengan baik.
