Abstract

The sunlight intensity level requirement for dragon fruit plants is more than 90%, which is essential for the photosynthesis process and the morphological development of the plant. This plant is classified as long-day plant, meaning that it requires at least 12 hours or more of sunlight to reproduce. Dragon fruit farmers utilize artificial lighting as an alternative to sunlight to support the plant's biological processes at night. The energy source is conventional electricity from grid (PLN). The design of an off-grid PV system at the Yosomulyo dragon fruit farm is carried out to support the farm's daily electricity needs. The design begins with field observations to obtain geographic data of the farm, daily electrical load profile data with amperes, calculating the PV system capacity, determining PV system components, and testing the performance of the design with PVSyst simulation. The simulation results of the PLTS design are 70.9% with an inverter variation of 6500 W, solar modules of 550 Wp, batteries of 200 Ah 12 V at a system voltage of 48 VDC, and an autonomy day of 1.

Abstract

This paper discusses a cascade inverter 9 three-phase power system using a Cascade H Bridge inverter type with a DC Fuel Cell voltage source. The goal is to reduce the Total Harmonic Distrotion (THD) content in the output waveform in accordance with IEEE 519 standards below 5%. At each level the inverter is supplied by the fuel cell as a DC source and in series with the next level inverter circuit to get 9 output voltage levels. The switch performance of each level is controlled by PWM pulses at the level of different amplitudes but the same frequency. Unlike conventional approaches that rely solely on low-level inverters or fixed DC sources, this study proposes the implementation of a nine-level cascade H-Bridge inverter topology powered by a DC fuel cell with three-phase multi-carrier modulation technique to produce high-quality sinusoidal voltage. This system shows increased efficiency, harmonic reduction, and more optimal utilization of green energy. Simulation results show that the output voltage form of each phase inverter is a 9-level ladder wave with a THD of 13.67%. By installing a low pass filter, the output voltage waveform changes to sinusoidal with and THD can be reduced to 2.92%. The power system with this THD value can still be tolerated to occur in an electric power system

Abstract

The issue of limited human resources in the agricultural sector, particularly in terms of labor availability, has led to increased operational costs and decreased harvesting efficiency. On the other hand, existing IoT-based tractors are generally large-scale and expensive, making them inaccessible to smallholder farmers. To address this challenge, this study proposes the development of a modular attachment for conventional two-wheeled tractors. The device is designed to be efficient, affordable, and capable of minimizing dependence on human labor without requiring the replacement of the main tractor unit. The proposed solution includes a dual blade system (for both tilling and harvesting), a harvest quality detection system, and IoT-based autonomous navigation. All components are integrated into a single functional module that can be attached to existing two-wheeled tractors owned by farmers. This approach eliminates the need to purchase a new tractor, as the innovation enhances the functionality of equipment already in use. Additional advantages include the installation of a mechanical counterweight to stabilize the tractor during operation and the integration of quality detection capabilities, which improve efficiency by enabling simultaneous harvesting and quality monitoring. This study demonstrates that transforming conventional tractors into semi-autonomous systems can significantly enhance labor efficiency, harvesting precision, and reduce operational costs. The innovation offers a sustainable approach to agricultural modernization through the integration of modular technology and IoT, tailored for small to medium-scale farming.

Abstract

Indonesia as a maritime nation with vast and strategic oceanic territory, continues to develop efficient and innovative ship technologies. This research focuses on the design and construction of a speed monitoring system for a trimaran vessel using the Pixhawk controller. The system integrates a Pixhawk autopilot unit as the main controller, an STM32 microcontroller for processing, dual BLDC motors, an internal combustion engine (ICE), and a remote control system. The Internet of Things (IoT) platform is employed for real-time data logging and monitoring. Experimental tests were conducted on five reference speed levels slow patrol, reconnaissance, medium patrol, cruising, and chase modes. Quantitative results show that the system achieved rapid response times at medium speeds, with stable operation and an average delay below 0.5 seconds. At high speeds, however, stability decreased by 15–20% due to environmental and load variations. Remote control communication maintained stable performance up to 210 meters with obstructions and 280 meters without obstacles. The results demonstrate that the system effectively supports real-time speed monitoring for trimaran vessels. The novelty of this study lies in the integration of hybrid propulsion and adaptive control within an IoT-based Pixhawk monitoring system, contributing to advancements in smart maritime technology.

Abstract

Reliability of electricity supply is crucial for ensuring the continuity of company operations, particularly for server systems. This research designed a prototype IoT-based Automatic Transfer Switch (ATS) and Automatic Main Failure (AMF) system integrated with the Blynk application. The goal was to test whether the Blynk application could monitor power supply switching and automatically store voltage data using the Blynk Cloud Data Logger. This system was developed using a WeMos D1 R32 microcontroller and a PZEM-004T sensor to measure voltage and current from two sources: the state electricity company (PLN) and a generator. Measurement data was displayed in real time in the Blynk application and recorded to the cloud. Testing was conducted over 14 days at one-hour intervals, during which the system was tested under both automatic and manual switching conditions. The results showed that the Blynk application could display power supply switching status with a fast response and accurately log voltage data. This demonstrates the effectiveness of Blynk as a cloud-based monitoring and data logging tool in the IoT-based ATS-AMF power supply system
