This study aims to design and implement a load cell sensor system for fresh fruit bunches (FFB) based on mass, using a conveyor and load cell sensor. The system is designed to detect the weight of the bunches in real time and separate them according to the minimum weight criteria established by the Indonesian Ministry of Agriculture Regulation No. 1 of 2018, which is above 3 kg. The mass de…
A machine vision system has been developed to assist in the automatic and real-time sorting and grading of oil palm Fresh Fruit Bunches (FFB), especially for detecting their ripeness level. The system consists of a computer vision unit, a conveyor, a control circuit, and a separation arm. The conveyor speed and the camera's frame rate per second (FPS) influence the accuracy of image detection. …
The manual classification process of fresh fruit bunches (FFB) in oil palm has limitations, particularly with stacked objects, due to subjective assessment and low efficiency. This research develops an automated system based on computer vision using the YOLOv8 algorithm to detect and classify normal and defective FFB (empty bunches, rotten, long stalks, and long thorns) stacked on a conveyor. A…
The multispectral imaging has been used in agriculture to evaluate fruits and vegetable. This system consists of a light source, monochrome camera and two color filters. In the implementation of the size of the sorted and graded FFB, it varies causing varying intensity because the working distance which varies causes errors in determining the maturity of oil palm FFB because the shadow of the…
Oil palm is a major commodity in Indonesia’s plantation industry. However, the identification process of fresh fruit bunch (FFB) varieties such as Dura and Tenera is still carried out manually and destructively, making it inefficient and tiring. This research aims to develop a non-destructive identification system based on ultrasonic sensors and Artificial Neural Networks (ANN) to distinguish…
Oil palm is a primary commodity in Indonesia’s plantation industry, with the production of fresh fruit bunches (FFB) increasing annually. However, the process of identifying FFB varieties such as Dura and Tenera is still performed manually using axes in a destructive manner, which is inefficient and damages the surface of the fruit. Non-destructive imaging methods have emerged to address this…
This research is titled "Mapping the Potential of Groundwater Using the Schlumberger Configuration Geoelectric Method in Jati Mandiri Housing, Air Putih Village, Tuah Madani District, Pekanbaru City". The main objective of this study is to evaluate the groundwater resource potential in the area, where most residents still rely on boreholes and dug wells as sources of clean water. The geoelectri…

The main challenge in energy management lies in the instability of power supply from different sources and the need for an automated system that efficiently switches between energy sources. This study aims to design and develop a power management module based on Arduino Uno that is capable of automatically monitoring and controlling the transitions between power sources. The system uses INA219 …
People tend to have a less productive lifestyle, excessive use of electronics and consumptive behavior that affects sleep patterns. Bad habits carried out continuously cause hormonal imbalances characterized by insomnia and depression. The amino acid L-Tryptophan (Trp) is reported to improve sleep quality and early treatment of early symptoms of insomnia without depressant drugs. However, the u…
This study aims to design a system for detecting ripeness levels and automatically counting oil palm Fresh Fruit Bunches (FFB) using a computer vision approach based on YOLOv8 and ByteTrack algorithms. The main issue addressed is the low efficiency and accuracy of the manual sorting process based on ripeness level, which is still commonly used in the palm oil industry. The system is designed to…
The development of optical communication technology demands stable and efficient transmission media, one of which is single mode fiber (SMF). One of the main challenges in optical fiber performance is the birefringence phenomenon, which is the difference in refractive index between two orthogonal polarization directions, which can cause polarization dispersion and decreased transmission quality…
