Abstract

Information technology (IT) has been applied to various sectors, including industry, government, education and health. However, technological sophistication is also accompanied by threats in terms of data security. For this reason, a system is needed that can secure the data, where attacks on data often occur from networks connected to the internet. The world of education today is also very dependent on technological sophistication, especially in data storage. One that utilizes this technology is SMPN I Muara Kelingi. The problem currently faced is the lack of a data security system on the Dapodik Server at SMPN I Muara Kelingi. The attack that can attack the network is in the form of a sniffing attack. The purpose of making this system is so that the data or information contained in the system cannot be accessed by unauthorized persons and to prevent damage to the system. By using the Security Policy Development Life Cycle (SPDLC) and using Snort as a tool to detect packet sniffing attacks, the school can quickly detect attacks that occur on the school Dapodik Server.

Abstract

This paper presents the design of self-balancing electric scooters, especially those that use two wheels. Scooter with two wheels cannot stand in balance without a control of speed and direction on both wheels. Two-wheel scooter balance is also a non-linear problem which is quite difficult to solve. For this reason, the Fuzzy Logic Controller (FLC) is designed to control the balance of the two-wheeled scooter. As an input parameter for the FLC control, an accelerometer sensor is used which can detect the elevation angle of the scooter to the ground. FLC is designed using twenty-five rules. The test results show that the scooter can maintain its balance between elevation angles of -30° to 30°.

Abstract

The school library is a place to manage a collection of books and libraries owned by an agency. At SMP Negeri 1 Trowulan, the process of filling in member data, borrowing books, returning books, extending the borrowing period, inputting new book data is still done manually which requires ledgers to record all data. With the creation of a web-based inteligent library information system, business processes at SMPN 1 Trowulan will become more effective and librarians will be more helped. This study aims to build a library information system at SMPN 1 Trowulan that is in accordance with the needs of business processes. Done using the Prototyping method, using the CI (CodeIgniter) programming language, and using the MySQL database as the database tool.

Abstract

Distribution network reconfiguration serves to mitigate power losses in distribution networks. Each distribution network encounters disturbances resulting in power losses and voltage drops. Various methods can reduce power losses and improve voltage values in distribution networks. This research presents an effort to reduce power losses using the Binary Particle Swarm Optimization (BPSO) method through a case study on the Barata Feeder. Distribution network reconfiguration occurs by adding new channels without altering existing ones and without relocating loads through additional switches in the distribution network. The creation of new channels assumed the use of the same type and conductor. Planning five new channels using the Binary Particle Swarm Optimization (BPSO) method could decrease power losses from 242.2333 kW before distribution network reconfiguration to 93.1859 kW. Thus, it achieved a reduction of 62.1555 kW.Kata kunci: Reconfiguration, Distribution Network, Power Losses, Voltage, Binary particle Swarm Optimization

Abstract

Bed Occupancy Rate (BOR) merupakan indikator penting dalam menilai efisiensi dan mutu pelayanan rumah sakit, khususnya pada layanan rawat inap. Fluktuasi BOR yang tidak terkelola dengan baik dapat berdampak pada pemborosan sumber daya maupun penurunan kualitas layanan kesehatan. Penelitian ini bertujuan untuk memprediksi nilai BOR di Rumah Sakit Haji Surabaya menggunakan metode Prophet berbasis deret waktu. Data yang digunakan berupa data BOR bulanan periode Januari 2021 hingga Juni 2025 sebanyak 54 observasi. Hasil analisis deskriptif menunjukkan rata-rata BOR sebesar 61% dengan variasi moderat. Model Prophet diterapkan dengan pembagian data latih sebanyak 48 observasi dan data uji sebanyak 6 observasi. Evaluasi model menunjukkan performa yang baik dengan nilai MAE sebesar 2,16% dan MAPE 3,72% pada data latih, serta MAE 3,82% dan MAPE 6,13% pada data uji. Hasil ini mengindikasikan bahwa metode Prophet mampu menangkap pola tren dan musiman BOR secara akurat, sehingga dapat digunakan sebagai alat pendukung pengambilan keputusan dalam perencanaan kapasitas rumah sakit.

Abstract

The reliability of the electricity distribution system is very important for PLN. With a high level of reliability, PLN can ensure that electrical energy is distributed properly to customers. A high level of reliability is a guarantee for customers to get electrical energy. Some researchers measure reliability using the SAIDI (System Average Interruption Duration Index) and SAIFI (System Average Interruption Frequency Index) values. Apart from that, there are also those who use the FMEA (Failure Modes and Effects Analysis) method. In this study, researchers carried out reliability classification based on the SPLN 59-1985 standard using the artificial neuron network single perceptron method. Researchers used 3 neurons as input, namely the SAIDI value, SAIFI value and bias. The training data used is SAIDI value data and SAIFI value data for 10 months in 2021. The single perceptron neuron network application was created using C++ language with a learning rate of 0.1, and a sigmoid signal as the activation. So the weighting values obtained for 3 neurons, namely -3.95772 (W[0]), 1.15408 (W[1]) and 1.45799 (W[2]) in 6 training times to classify the level of reliability.

Abstract

Peningkatan kebutuhan energi global mendorong peralihan menuju sumber energi yang lebih berkelanjutan, salah satunya melalui pemanfaatan energi surya. Meskipun teknologi panel surya telah berkembang, efisiensinya masih sangat dipengaruhi oleh faktor eksternal seperti debu dan kotoran yang menempel pada permukaannya. Penelitian ini bertujuan untuk merancang dan menguji sistem pembersihan otomatis panel surya berbasis motor stepper guna meningkatkan efisiensi energi yang dihasilkan. Sistem ini bekerja dengan menggerakkan wiper secara presisi untuk membersihkan permukaan panel secara berkala, menggunakan energi yang dihasilkan oleh panel itu sendiri, tanpa membutuhkan sumber daya eksternal. Metode penelitian ini mengukur pengaruh variabel seperti ketinggian panel, kecepatan wiper, dan waktu pembersihan terhadap efisiensi panel surya. Hasil penelitian menunjukkan bahwa sistem pembersihan otomatis dapat meningkatkan efisiensi energi panel surya hingga 30%, memperpanjang umur operasional panel, dan mengurangi biaya pemeliharaan. Dengan menggunakan motor stepper, sistem ini juga menawarkan solusi hemat energi yang efisien, di mana wiper bergerak secara terkontrol berdasarkan kebutuhan pembersihan. Penggunaan teknologi ini diharapkan dapat mempercepat adopsi energi surya, terutama di daerah dengan kondisi lingkungan ekstrem, serta mendukung transisi menuju penggunaan energi yang lebih ramah lingkungan dan berkelanjutan.
