Abstract

The efficiency of palm oil harvesting is crucial to ensuring optimal yield and quality of fresh fruit bunches (FFB). Traditional manual harvesting methods often result in inconsistent outcomes due to human error and subjectivity in ripeness evaluation. This study proposes an intelligent, image-based harvesting decision system that utilizes Convolutional Neural Networks (CNN) and Support Vector Machines (SVM) to automate the classification of palm oil FFB ripeness. High-resolution images of palm fruit are processed using Python-based frameworks (Google Colab 3.10.12, YOLOv8) to extract features such as color and texture, which are then used to train the CNN and SVM models. The system architecture includes stages for image acquisition, preprocessing, feature extraction, classification, and decision-making. Both CNN and SVM were evaluated for performance using accuracy, precision, recall, and F1-score. The experimental results demonstrated high classification accuracy, with CNN achieving an average of 0.97 and the highest result recorded at 0.89. The system significantly enhances harvesting decision accuracy and reduces dependence on manual inspection. This study demonstrates the viability of using deep learning and machine learning algorithms for real-time agricultural decision-making. The integration of CNN and SVM not only improves productivity but also contributes to sustainable practices by reducing waste and labor intensity. The proposed system offers a scalable solution that can be adapted for broader smart farming applications, supporting national goals of digital transformation and energy efficiency in agriculture.

Abstract

Variable voltage DC power supply that has wide range of power, lightweight and inexpensive is quite difficult to obtain. This research designs and tests a DC power supply without a transformer using switching technology that utilizes TRIAC. The 220 Volt AC power source is converted to DC electricity by the method of cutting off some AC waves signal, using TRIAC, and then rectifying it with diodes and filters. DIAC functions as a trigger TRIAC at the specified time, by turning the variable resistor. The test results show that the output DC power voltage can be adjusted from 5 Volts to 75 Volts by adjusting the DIAC resistance and the load resistance. The results of the series image characteristics are given 2-dimensional and 3-dimensional graphics.

Abstract

This paper discusses the simulation of the Fuzzy-PID hybrid algorithm as a method for controlling the speed of a DC motor compared to the usual PID method. Comparisons were also made to the membership functions used in the fuzzy logic fuzzification process. Membership functions that are used are triangular, trapezoidal, and gaussian shaped function with each having 3, 5, and 7 as the number of membership to be compared. The performance of this control is compared by looking at the results of the step unit responses and the ability in tracking signals. The simulation results show that the Fuzzy-PID algorithm is superior to the ordinary PID algorithm but slower on computation time. The results of the comparison in the fuzzification process shows that the more number used in membership function, the faster the response reaches the set point, while the difference in shape has little effect on the response. The best results are achieved by fuzzy triangle shaped function with 7 membership number.

Abstract

Deafness is a condition in which a person cannot hear due to a disturbance in his hearing organs. In communicating, most of the deaf sufferers only receive hearing aids. WHO (World Health Organization) initiated the Sound of Hearing 2030 by preventing hearing loss by 50% in 2015 and 90% in 2030. The main objective of Sound of Hearing is to develop a comprehensive, inclusive, and sustainable ear care program. Various studies on tools for deafness have been developed. However, this tool is only used to help deaf hearing but not to help speech learning (learn to speak). Thus we need hearing aids and speech learning tools for the deaf. This tool can be a government program, namely supporting a diffable-friendly Indonesia. The tool is designed like a headband, where the headband is composed of a row of vibrating modules that will be connected to the Google Assistant on a smartphone, so that any sound received by the Google Assistant will be sent to the tool to be converted into a vibration pattern. It is from these vibration patterns that a deaf person will get experience in recognizing sounds and learn to speak based on the vibration patterns that are formed. With the design of this tool, it hoped that it can help deaf people and get support from the community and government to create a diffable-friendly Indonesia.

Abstract

The limited capacity of renewable energy sources in the grid utility is a challenge. Increasing the capacity of renewable energy sources is supported by energy storage in the grid. The Battery Energy Storage System (BESS) allows storing more electricity from New and Renewable Energy (EBT) sources to meet load requirements. This paper designs a techno-economic study of various battery technologies using HOMER (Hybrid Optimization Modeling Software) software simulation. Simulations are made for grid-connected photovoltaic systems in Indonesia. HOMER is used to find the energy cost ($ / kWh) for each type of battery technology and battery system size. The simulation is designed using 1MWp PV component parameters, inverter, energy storage to be compared, residental load, and connected to the grid. The results will help to determine which technology and battery size is more suitable for the system. The findings from this paper resulted in the lowest Levelized Cost Of Energy (LCOE) of $ 1.03 in solar power generation.

Abstract

Design of electrical system in the Faculty of Economics and Management Bogor Agricultural Institute was based guidance consisting of PUIL, SNI, as well as provisions of modern security and technology and aesthetic beauty. Design is also based on the relevant IEC standards, specifically IEC 60364. In the electrical system, it is necessary to pay attention to the conductor and safety factor to minimize power losses and drop voltage. Losses on the customer side due to drop voltage besides damaging electrical equipment is customers only can have a voltage less than 220 V. The distance between load panel and main panel is directly proportional to the drop voltage value, much farther the load panel to the main panel, resulting greater drop voltage value produced. The calculation of drop voltage based on total load, length, and area of conductor. To overcome the problems that occurred in this case study, the conductor uses 1.25 times the nominal current as a safety factor. The selection area of conductor can be said to be quite good with the farthest drop voltage value from SDP-TR is 0.89%. The total amount of electricity in the building is 158.33 kVA, assuming that if there is an additional 5-10 years, the total electric power and 15% of the others SDP is 182.04 kVA.

Abstract

The diminishing availability of non-renewable energy resources such as coal, oil, and natural gas has prompted efforts to seek sustainable energy alternatives. One promising alternative is wind energy, which can be converted into electricity through wind turbines. However, Horizontal Axis Wind Turbines (HAWTs) have limitations in capturing wind from various directions, affecting operational efficiency. Therefore, this research attempts to address this issue through an innovation in yawing-based monitoring systems integrated with HAWTs and Internet of Things (IoT) technology. The yawing-based monitoring system is designed to monitor the performance of HAWTs in real time, including wind speed, rotations per minute (rpm), electrical current, and voltage. Data obtained from this monitoring system is used to identify potential damage to HAWTs, enabling timely preventive measures. Furthermore, this monitoring system can enhance the operational efficiency of HAWTs, reduce maintenance costs, and extend their lifespan. The results obtained from the comparison between the conventional system and the system with active yawing show a significant increase in power generated by the turbines equipped with the active yawing system. On average, turbines with the conventional system produce 213 watts of power, while turbines equipped with the active yawing system reach a power output of 296 watts. This represents a 39% increase in turbine efficiency, enhancing wind energy capture efficiency. These findings confirm that the integration of the active yawing system can optimally align the turbines with the incoming wind direction, thereby improving the overall system performance.
