Palm oil fresh fruit bunch ripeness grading identification using color features

This research investigates the ripeness grading identification of the palm oil FFB using colorfeatures that are color histogram, color moment and color correlogram. Palm is harvestedduring the optimum stage of its ripeness since it improves the FFB oil quality and quantity.Harvesting wrong bunches decreases the oil extraction rate of the palm. A preliminaryresearch on the palm oil FFB grading identification is conducted. Each ripeness stage has itsown unique color. A study on color features is investigated.A new dataset of images of FFB isconstructed. A comparative study between Support Vector Machine (SVM) and Naïve Bayesclassifiers has been performed using the values of color histogram, color moment and colorcorrelogram. The results of the experiments indicate that color moment with SVM produce ahigher palm oil FFB ripeness grading identification accuracy compared to color histogramand color correlogram.Keywords: color features, fresh fruit bunch (FFB), Naïve Bayes, ripeness stage, supportvector machine.

Electric Wheelchair Controlled by Joystick and Android/iOS Smartphone

A wheelchair is used by people who are difficult to walk because of having physical problems, injuries, or disabilities. There are many options and different types of wheelchairs such as manual wheelchairs, electric wheelchairs, and scooters depending on the patient's financial ability, physical limits, and strength. Not all people with movement disabilities have enough strength especially elders. Moreover, there is no wheelchair controlled by smartphones currently available in the market and even custom-made electric wheelchairs are very expensive. Therefore, the main objective of this project is to provide a solution to this matter by modifying an existing manual wheelchair that would use smartphones (android/iOS) and joystick to control its movement. So, the rationale of this project is it can help patients with movement difficulty to move easily with significantly at a lower cost. Implementation of this project will be using System Development (SDLC) Life Cycle methodology that divide the complex task into several phases of development. This project will be divided into two parts, namely the implementation of hardware and software. The main hardware of this system consists of Arduino microcontrollers and motors that can be controlled using a smartphone via Bluetooth module and joystick. Ultrasonic sensors are located on the rear of this wheelchair to detect objects or obstacles and buzz the buzzer so that the person who uses it can be acknowledged when there are objects behind during reverse movement. The software part will consist of Arduino programming using Arduino Integrated Development Environment (IDE) software and mobile apps programming using Massachusetts Institute of Technology (MIT) App Inventor software. In the end, the implementation of this project can be used in universities, companies, hospitals, and at home as well to facilitate someone's movement without having to rely too much on help from others. In conclusion, this project is expected can help the disability and elder to move freely and control the electric wheelchair by themselves independently
