Abstract

PT. Palokoto Agro Industri masih menghadapi permasalahan dalam sistem pencatatan gudang dimana masih mengandalkan microsoft excel dalam pencatatan gudang yang tidak efektif untuk data besar, rawan kesalahan, dan kurang aman. Proses pembaruan stok manual menambah beban kerja serta menurunkan akurasi data. Ketiadaan akses real-time juga membatasi pimpinan dalam memantau keadaan gudang dan mengambil keputusan tepat waktu. Untuk mengatas permasalah tersebut, diusulkan pengembangan sistem Point of Sales berbasis web yang memungkinkan sistem pencatatan gudang yang lebih efektif dan efisien. Sistem ini dibangun dengan pendekatan prototype dengan arsitektur Model-View-Controller (MVC) menggunakan framework Laravel dengan fitur sesuai dengan standar pencatatan gudang, rekapitulasi transaksi  barang masuk dan keluar secara otomatis, memberikan akses yang luas bagi pimpinan untuk memantau keadaan gudang dan pembuatan laporan yang cepat dan kekinian. Berdasarkan hasil pengujian menggunakan standar ISO/IEC 25010, sistem Point of Sales ini telah memenuhi semua aspek kualitas perangkat lunak, seperti functional suitability (100%), reliability (rating A), usability (89,5%), maintainability (rating A), performance efficiency (100%), portability (100%), compatibility (100%), dan security (rating A). Oleh karena itu, aplikasi yang dibuat telah memenuhi kriteria kualitas yang diperlukan serta dapat digunakan sebagai solusi dalam penanganan pencatatan gudang di PT Palokoto Agro industri.

Abstract

Oil palm plantations require continuous and reliable monitoring to ensure efficient irrigation, yet many farmers still depend on manual watering methods that are time-consuming and inconsistent. To address this issue, this study develops an Internet of Things (IoT)-based irrigation monitoring system using the MQTT communication protocol to support real-time data delivery and automated control. The system integrates ESP32 microcontrollers, soil moisture and environmental sensors, HiveMQ Cloud as the MQTT broker, and Telegram Bot notifications. The research was conducted on a 27 m × 70 m oil palm plantation consisting of 24 trees. System testing was performed over seven days with two irrigation sessions daily, during which sensor data transmission and notification timestamps were recorded. QoS parameters including throughput, packet loss, delay, and jitter were analyzed using Wireshark. The results show that sensor data and irrigation notifications were consistently delivered within 3–5 seconds, demonstrating stable real-time communication. QoS evaluation indicates 0% packet loss, an average delay of 180 ms, and an average jitter of 0.17 ms, with an overall QoS index of 3.02, classified as “Satisfied.” These findings confirm that MQTT provides reliable communication performance in plantation environments and effectively supports automated irrigation monitoring for improving agricultural efficiency.

Abstract

Pengabdian kepada mayarakat ini dilaksanakan di Desa Bunsur Kecamatan Sungai Apit Kabupaten Siak Propinsi Riau dengan khalayak sasarannya masyarakat nelayan desa tersebut. Sektor pertanian dan nelayan merupakan profesi yang sangat dominan sebagai sumber kehidupan di desa ini. Berdasarkan informasi kepala desa, desa ini terkenal sebagai penghasil ikan Bilis Asam. Berdasarkan hasil survei harga jual ikan ini di Pasar Panam Kota Pekanbaru berkisar Rp. 125 ribu per kg. Harga ini menunjukkan nilai keekonomian yang tinggi dan sangat menjanjikan bagi kehidupan masyarakat nelayan di Desa Bunsur ini. Dari informasi para nelayan, pada musim hujan semua hasil tangkapan ikan ini tidak dapat dijual bahkan dibuang begitu saja karena membusuk akhibat tidak bisa dikeringkan karena tidak ada cahaya matahari. Keadaan ini dapat diatasi dengan membuat sebuah tempat pengeringan khusus dengan teknik rekayasa cahaya lampu dalam sebuah ruangan yang dirancang sedemikian rupa. Ruangan ini akan dapat menyelamatkan gagal produksi ikan Bilis Asam masyarakat nelayan di Desa Bunsur dengan demikian kehidupan mayarakat nelayan dapat lebih stabil di setiap musim, baik musim hujan maupun musim panas. Pengeringan ikan yang akan dirancang adalah tipe pengeringan mekanis dengan rekayasa cahaya lampu. Pengeringan ikan ini akan dibuat transparan yang dikelilingi akrilik bening dan tembus cahaya. Penjemuran tembus cahaya ini bertujuan agar di musim panas masyarakat juga tetap menggunakan penjemuran ini.  Penjemuran ini akan dipasang sensor sehingga pada saat hujan atau panas pengeringan tetap berfungsi dengan baik dan otomatis. Sistem ini dirancang agar nelayan tidak perlu kuatir ikannya terkena hujan atau tidak kena panas karena sudah beroperasi secara otomatis

Abstract

This study discusses the development of a web-based property management system designed to meet the needs of two types of users: administrators and tenants. The system was developed using the Research and Development (R&D) method with the Rational Unified Process (RUP) approach and implements the Model-View-Controller (MVC) architectural pattern. The application was built using the Laravel framework and MySQL database. It consists of two main interfaces: an administrator interface that includes a landing page, login page, and dashboard, and a tenant interface that is designed to be user-friendly. The features available in the administrator interface include property management, tenant data management, financial management, complaint handling, and user account management, all aimed at improving operational efficiency. System testing was conducted using SonarQube to evaluate code quality, PageSpeed Insights to assess application performance, and the User Experience Questionnaire (UEQ) to measure user experience. The test results indicate that the application meets various important quality aspects, including functional suitability, reliability, maintainability, performance efficiency, portability, compatibility, security, and usability. Despite the system’s many advantages, several areas for improvement remain. Suggested enhancements include integration with WhatsApp for better communication, a notification system to keep users updated, the addition of diverse payment options, and optimization of the user interface for a more responsive and attractive design. Therefore, the developed application is expected to improve the efficiency of property management and enhance user satisfaction, particularly for administrators managing property units, tenant data, finances, complaints, and user accounts.

Abstract

Efforts and strategies have been done both by the providers of electrical energy and the government to handle the increase in electricity demand.  However, there has been no satisfactory result. The government has set a major policy on energy management, namely conservation and energy diversification in order to reduce dependence on non-renewable energy sources and utilize renewable energy available in areas where power plants will be built to meet the growing demand for electricity. Riau Province in addition to located in tropical climates and many of its areas are on the coast that its existence is very far for affordable network of PLN electricity, therefore the provision of solar power plant is one appropriate alternative, to meet the needs of electrical energy for the needs of the population. While the output voltage generated by solar cells is not constant, but it depends on the natural conditions that at any time vary the intensity of sunlight, so that the output voltage of the solar cell is also not constant and varies throughout the daytime. In general, commercial equipment has specification limits for ± 10% voltage variation. Disturbances such as voltage varization, if not handled seriously can cause damage to consumer electrical equipment, in addition to the use of electrical energy, in the form of varying output voltage resulting in expensive cost. To overcome the problem of voltage variations produced solar cell can be used prototype dc to dc converter using boost converter technology, which  automatically  adjust  the  output  voltage  according  to  the  desired  voltage.Designing  DC  to  DC Converters To Stabilize Solar Cell Outputs Using Boost Converter Technology has been tested for performance through the output voltage of a 100 WP solar cell panel whose values vary from 13.5 volts to 20.8 volts as a boost converter input and produce a regulated output voltage 24 volt. Based on the results of prototype testi ng dc to dc converter using booast converter technology that has been designed to produce a voltage regulated voltage of 24 volts direct current declared valid. The valid intent here because the output voltage is still dirange 24 volts ± 10%.
