Abstract

Perkembangan teknologi informasi dan komunikasi (TIK) telah menjadi elemen penting dalam berbagai sektor, termasuk pendidikan, bisnis, hingga pemerintahan. Di era digital ini, diharapkan proses administrasi dan layanan publik dapat menjadi lebih cepat, efisien, dan terintegrasi. Kelurahan Sei Enam, yang terletak di Kabupaten Bintan, meskipun telah menunjukkan adaptasi yang baik terhadap teknologi, tapi masih menjalankan proses administrasi secara manual, seperti pengurusan surat ahli waris, surat keterangan penghasilan, surat kematian, dan surat keterangan domisili. Selain itu, sistem pengaduan masyarakat belum terintegrasi, sehingga pengelolaan keluhan warga menjadi kurang efisien. Penelitian ini mengusulkan pembuatan website pelayanan administrasi bagi masyarakat Kelurahan Sei Enam. Website dibangun menggunakan metode Rapid Application Development (RAD), sedangkan bahasa pemrograman yang digunakan adalah PHP, JavaScript, dan HTML dengan memanfaatkan framework Laravel dan framework Bootstrap. Pengujian terhadap sistem menggunakan metode blackbox testing. Hasil pengujian menyatakan bahwa website ini dapat berfungsi sesuai dengan spesifikasi dan kebutuhan pengguna, serta mempermudah permintaan surat kapan saja dan di mana saja tanpa harus mengunjungi kantor kelurahan. Keberadaan website ini juga meningkatkan efisiensi, efektivitas, dan transparansi dalam proses administrasi dan pengarsipan.

Abstract

Tides are the periodic rise and fall of sea levels caused by the gravitational effects of the moon and the sun. This tidal phenomenon can be measured manually or automatically using instruments. The objective of this study is to design and develop a tide gauge instrument using the JSN-SR04T sensor based on the Internet of Things (IoT). The research method includes hardware design, electrical design, firmware development, and dashboard creation. Once the system design is completed, the components are assembled. Functional and laboratory tests are conducted to ensure that each component operates properly, followed by field testing. The tide gauge instrument is capable of operating for 7 days with good accuracy in the measurement range of 25 cm to 200 cm (with an error between 0.02 and 0.16 cm). Field observations indicate that the type of tide corresponds to previous studies, which is a mixed tide. The DS18B20 sensor produced temperature readings that matched those of a standard thermometer.Pasang surut merupakan gerak naik turun muka air laut secara periodik yang disebabkan oleh efek gravitasi bulan dan matahari.

Abstract

Within the context of energy-efficient automation, simple electronic control systems remain an essential research area for practical yet low-cost solutions. This study aims to evaluate the functional performance of two circuit prototypes based on the IC Timer 555 a Laser-LDR Security Alarm and a Blinking Turn-Signal Light to address the need for reliable automation in energy engineering applications. The methodology follows a structured three-step approach: (1) circuit simulation using tools such as Multisim or Proteus, (2) physical realization via PCB design and assembly, and (3) functional testing to verify performance metrics of each prototype. Results demonstrate that the security alarm effectively detects laser beam interruption via the LDR in a monostable (latch) configuration, while the turn-signal circuit reliably generates periodic LED blinking using the astable mode. Together, these prototypical systems illustrate how simple timing control circuits using IC 555 can deliver versatile, cost-effective automation suitable for practical applications in energy engineering.

Abstract

To reduce pollution caused by fuel spills during the refueling process, this research designs and implements an automatic fuel filling device on a wooden boat with a capacity of 6 GT. This system consists of the JSN-SR04T ultrasonic sensor unit, an automatic pump, Neopixel-based LED visual indicators, and a microcontroller as the control center. This tool is designed to automate the fuel transfer process from the dock tank to the ship's tank without the need for manual intervention, thereby increasing operational efficiency and safety. Laboratory tests show that the system has high accuracy, with a Root Mean Square Error (RMSE) value of 0.30 cm, equivalent to an accuracy level of 99.39% in measuring the fuel surface height. In field tests on the Sungai Ungar–Batam route, this device was able to fill 75.76 liters of fuel in 9 minutes and 29.15 liters in 3 minutes automatically. The system is capable of detecting fuel levels, activating the pump when needed, and providing real-time visual notifications. The system's performance is affected by turbulence in the tank when the ship is moving, which reduces the stability of the sensor readings. Therefore, the use of sensors that are more resistant to dynamic conditions and the expansion of testing on larger capacity ships will be the next direction for development.

Abstract

Agricultural sustainability is essential for rural communities, particularly in Kampung Gisi, where celery cultivation is a major source of household income. However, farmers continue to rely on manual irrigation, which is labor intensive, time consuming, and often inefficient in terms of water use. This study aimed to design and implement a solar powered automatic irrigation system that improves water efficiency while reducing farmers’ workload. The approach addressed these challenges by developing an autonomous system powered by solar energy and guided by soil moisture sensing to optimize water delivery. The proposed system integrates a solar panel, an ESP32 microcontroller, a soil moisture sensor, a relay module, and a DC pump to enable irrigation decisions based on real time soil moisture data. Implementation and testing were conducted in Kampung Gisi, Bintan Regency, Riau Islands. Data collection included site visits and semi structured interviews with local farmers to document existing irrigation practices and constraints. Field trials indicated that the system effectively automated irrigation, and the results showed an approximately 30% reduction in water use compared with manual watering. Prior to deployment, farmers typically spent several hours per day irrigating, whereas the automated system substantially reduced time requirements, allowing farmers to allocate effort to other farm activities. Farmers also reported more stable soil moisture conditions, which supported healthier crop development and improved yields. Overall, the findings demonstrate that the system can enhance irrigation efficiency, reduce labor demands, and support more sustainable agricultural practices. Community participation was critical, as farmers developed technical familiarity and a sense of ownership, which supports long term system viability. These results underscore the role of appropriate technology in strengthening farming communities, and they suggest that future work should prioritize accessibility and scalability to support broader adoption.

Abstract

This research aims to analyze the comparison of the power output of monocrystalline solar panels with and without the use of mirror reflectors. The utilization of solar energy continues to grow, but the efficiency of solar panels highly depends on light intensity. The use of mirror reflectors is proposed as a method to increase the irradiation received by the panels. A quantitative experimental method was used, involving two identical configurations of monocrystalline solar panels: one without a reflector (control) and one with a mirror reflector. Voltage, current, temperature, and power data were collected every minute from 08:00 to 14:00 WIB using a microcontroller-based data acquisition system. The average results show an increase in the output power of the panel with a reflector (1.75W) compared to without a reflector (1.58W), although the temperature of the panel with a reflector is slightly higher. Analysis of variance (ANOVA) shows that the F-value (15206.12) far exceeds the F-table (2.012305) with a p-value approaching zero (0). These results statistically prove the existence of a significant difference in power output between the two configurations. Thus, it can be concluded that the use of mirror reflectors substantially increases the power output of monocrystalline solar panels, making it an effective strategy for optimizing the performance of photovoltaic systems.
