Abstract

Air adalah sumber kehidupan bagi makhluk hidup, selain untuk dikonsumsi, air juga berperan penting bagi kelangsungan makhluk hidup, bukan hanya untuk kebutuhan tumbuh-tumbuhan seperti perkebunan ataupun peternakan, salah satunya digunakan untuk kegiatan beribadah, khususnya umat Islam. penggunaan air ketika berwudhu seringkali terjadi pemborosan air, oleh karena itu penulis ingin merancang dan membuat sebuah alat yang dapat bermanfaat bagi masyarakat dan mempunyai nilai guna seperti: “rancang bangun kran air wudhu otomatis berbasis Arduino” yang bertujuan untuk meminimalisir pemborosan air dimeunasah maupun masjid. metode yang digunakan yaitu menggunakan gerak gelombang ultrasonik, seperti sensor proximity, yang berfungsi mendeteksi pergerakan manusia dengan jarak yang telah disetting pada program sesuai dengan kebutuhan jarak objek yang diperlukan, kemudian mengaktifkan keran/valve guna membuka maupun menutup keran air sehingga air dapat mengalir keluar dan dapat digunakan untuk berwudhu.

Abstract

The electricity distribution system generally starts from the generation, transmission, and distribution systems. In the distribution system, there are two channels, namely primary distribution with a voltage value of 20 kV and secondary distribution with a voltage of 220/380 V. Distributing electrical energy often experiences problems, one of which is the occurrence of energy losses during the distribution of electrical power to customers. Energy losses are energy losses due to technical and non-technical factors. This study evaluates energy losses due to technical factors in the express extension PL 03 and LW 09 PT PLN (Persero) ULP Lhoksukon. The method used to assess energy losses due to technThe calculation results show that theological factors with ETAP software simulations and more detailed technical shrinkage calculations, namely by calculating conductor and transformer shrinkage on the repeater. From the results of the ETAP simulation, it is obtained that the voltage losses of the PL 03 and LW 09 Lhoksukon ULPs still meet the standards according to SPLN 1: 1995 for a voltage of 20 kV where the limits set are +5% maximum and -10% minimum of the system voltage. The drop Voltage of PL 03 Extension is 7.6%, and LW 09 Extension is 8.25% of the nominal voltage of 20 kV. From the calculation results, of Drop Voltage of the PL 03 Repeater is 5.5%, and the LW 09 Repeater is 8.5% of the nominal voltage of 20 kV.

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

Undang Undang Nomor 11 tahun 2008 tentang Informasi Transaksi Elektronik atau UU ITE merupakan undang-undang atau peraturan yang sering kali bersentuhan langsung dengan berbagai orang, terutama pada era teknologi yang sedang berkembang saat ini. Secara umum, UU ITE masih belum tersosialisasikan dengan baik ke semua kalangan, termasuk pada kalangan siswa/siswi Sekolah Menengah Atas. Oleh karena itu, SMA Negeri 4 Lhokseumawe menjadi sasaran tim Pengabdian kepada Masyarakat Universitas Malikussaleh sebagai sarana untuk mensosialisasikan UU ITE. Hal ini dianggap penting karena pada saat ini kalangan muda (terutama siswa/siswi SMA) tidak terpisahkan dari teknologi internet. Sehingga perlu disampaikan bahwa ada sanksi atau hukuman yang berlaku apabila tidak waspada dalam memakai internet. Kegiatan sosialisasi ini diharapkan menjadi pembelajaran bagi siswa/siswi maupun guru-guru di SMA Negeri 4 Lhokseumawe agar lebih cerdas dan bijak dalam memakai internet, terutama untuk mencegah penyebaran berita hoax melalui social media maupun aplikasi chatting. Dari hasil sosialisasi yang dilaksanakan, dapat disimpulkan bahwa kesadaran dan pengetahuan siswa/siswi dan guru SMA Negeri 4 Lhokseumawe mengenai UU ITE masih rendah, sehingga sosialisasi ini diharapkan menjadi pembekalan agar mereka dapat waspada dalam menggunakan internet, terutama untuk menangkal berita hoax.
