Abstract

The development of technology in the field of electrical engineering and renewable energy provides great opportunities for the application of automation systems in agriculture. One of the common problems faced by farmers is the irrigation process, which is often carried out manually, requiring significant time, labor, and electrical energy consumption. This study aims to design and evaluate an automatic sprinkler system based on soil moisture sensors powered primarily by solar panels. The system employs an Arduino Uno as the main controller, a soil moisture sensor to detect soil conditions, and a water pump as the actuator for irrigation. Energy is supplied by a solar cell connected to a charging module and a battery as the power storage unit. The research method includes hardware design, software programming, and performance testing of the system under various solar panel tilt angles (30°, 37°, 45°, 53°, and 60°). The evaluation focuses on measuring the water discharge rate, irrigation time, and the efficiency of energy harvested from the solar panel. The results demonstrate that the tilt angle of the solar panel significantly influences irrigation performance. The optimal tilt angle was found at 45°, achieving a maximum discharge rate of 24.1 ml/s, which provides the most efficient irrigation compared to other angles. Although the discharge rate varies across different tilt angles, the total water volume delivered remains relatively constant, indicating that the difference is mainly reflected in the irrigation duration. In conclusion, the proposed automatic sprinkler system based on soil moisture sensors and solar energy offers an effective, efficient, and environmentally friendly solution to support sustainable agriculture. This study also contributes to the achievement of SDGs Goal 15 (Life on Land) by promoting renewable energy utilization and automation in agricultural land management.

Abstract

The objective of this research is to develop a home security system that utilizes facial recognition technology using the Haar Cascade method and ESP32CAM. In the face of criminal threats, the importance of an effective home security system is increasing. The facial recognition method employed in this study is the Haar Cascade method, which utilizes specific facial features to identify individual identities. The ESP32CAM sensor is used as a camera to capture facial images of the home occupants. The research involves the process of collecting facial image data from the home occupants, which is then used to train the facial recognition model. Subsequently, the model is implemented in a home security system that is connected to the internet and equipped with motion sensors. When motion is detected, the ESP32CAM camera captures an image of the visitor's face and compares it with the previously identified facial data. If a match is found, the system grants access to the visitor. The research results demonstrate that the developed home security system achieves accurate facial recognition with a high success rate. Therefore, this system has the potential to enhance home security and provide better protection for its occupants

Abstract

Simulation analysis and quantitative approaches have become very important in the foundry industry to improve product quality and minimize defects. This study aims to analyze macro defects, particularly porosity, in ashtray patterns produced through sand casting. A quantitative approach was used to identify and evaluate macro defects in the castings by utilizing 3D simulation techniques. This process involves taking macro images of the molded samples and then processing them to determine the porosity level. The porosity evaluation was carried out by comparing the simulation results with experimental data, thus enabling a more in-depth understanding of the factors affecting casting quality. The results of this study show the porosity formed by 3-dimensional simulation and the porosity percentage derived from statistical interpretation of macro photographs of sand casting materials. The findings are expected to make a meaningful contribution to the foundry industry, particularly in the effort to improve product quality through process optimization. This study also highlights the importance of quantitative and simulation approaches in analyzing and predicting casting defects, which can ultimately reduce production costs and improve product yield.

Abstract

Tangki Ukur Tetap Silinder Tegak (TUTSIT) selain dapat berfungsi sebagai alat penyimpanan dapat juga berfungsi sebagai alat ukur. Untuk menjaga akurasi hasil pengukuran, setiap alat ukur perlu dilakukan pengujian/kalibrasi. Terdapat beberapa metode untuk menguji TUTSIT, salah satunya metode optik dengan teodolit yang memiliki kelebihan yaitu waktu pengujian singkat dan keperluan jumlah personil yang sedikit. Selain kelebihan tersebut, teodolit tetap memiliki kekurangan yaitu harga yang mahal, menggunakan personil khusus, dan pengolahan data masih manual. Pengujian TUTSIT memanfaatkan fungsi teodolit untuk pengukuran sudut dan pengukuran jarak. Pada makalah ini membuat prototipe yang dapat mengukur diameter cincin referensi sebagai langkah awal pengujian TUTSIT. Diameter referensi ini sebagai acuan untuk pengukuran diameter pada cincin di atasnya. Proses pengujian prototipe yaitu dengan membandingkan terhadap teodolit pada posisi yang sama. Hasil pengukuran diameter cincin referensi oleh prototipe lebih besar 15,8 mm dibandingkan dengan teodolit. Adapun nilai-nilai karakteristik prototipe untuk akurasi sebesar 99,2%, presisi sebesar 99,9% dan kesalahan sebesar 0,8%. Prototipe ini memiliki potensi untuk dikembangkan sebagai alternatif ekonomis instrumen pengujian TUTSIT.

Abstract

Urbanisasi yang pesat mengurangi ruang terbuka hijau dan lahan pertanian di perkotaan, sehingga mengancam ketahanan pangan masyarakat. Pemberdayaan komunitas melalui urban farming menjadi alternatif strategis, namun kajian tentang peran komunikasi partisipatif dalam konteks ini masih terbatas. Penelitian ini bertujuan menganalisis strategi komunikasi partisipatif yang diterapkan Komunitas Selaras Farm dalam membangun kemandirian ekonomi warga melalui program urban farming. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan pengumpulan data melalui observasi, wawancara mendalam, dan dokumentasi. Tiga informan kunci dipilih secara purposive, yaitu Ketua, Koordinator, dan Pembina Komunitas Selaras Farm. Data penelitian kemudian dianalisis menggunakan model interaktif Miles dan Huberman (reduksi data, penyajian data, penarikan kesimpulan) dan keabsahan data diuji dengan triangulasi metode dan sumber. Hasil penelitian menunjukan bahwa Komunitas Selaras Farm menggunakan lima strategi komunikasi partisipatif yaitu komunikasi dialogis tatap muka dan virtual (grup WhatsApp), pelatihan dan edukasi anggota, keterlibatan aktif warga dalam pengembangan program, transparansi pengelolaan keuangan berbasis koperasi, serta membangun kepercayaan melalui pemanfaatan aset lokal. Strategi ini meningkatkan keterampilan bercocok tanam warga, mengurangi pengeluaran rumah tangga untuk pangan, dan menyediakan akses hasil panen dengan harga terjangkau. Komunikasi partisipatif efektif memberdayakan masyarakat perkotaan mencapai kemandirian ekonomi dengan mengoptimalkan lahan terbatas melalui urban farming. Penelitian ini berkontribusi pada pengembangan teori komunikasi partisipatif dalam konteks pertanian perkotaan dan menawarkan model pemberdayaan ekonomi berbasis komunitas yang dapat direplikasi di wilayah permukiman urban lain.
