Abstract

The Color and appearance are the most important indicators for a farmer to determine the condition of oil palm fresh fruit bunches (FFB) in the harvesting process. As the main attributes, the color and appearance become the guidelines for the initial assessment of fresh fruit bunches (FFB) of oil palm condition that is suitable or not for harvesting. In Facts, the FFB assessment activities are still carried out manually by utilizing the farmers visual, which is it will be prone to errors during the assessment. Due to this problem, it is important to automate the assessment of the color characteristics of oil palm FFB in order to minimize errors by farmers. The purpose of this study was to determine the efficiency of RGB color imaging techniques on oil palm FFB. The method used is processing and color analysis on 30 FFB images based on smartphone cameras to find the correlations for each color. Each color channel R, G and B in the FFB images was extracted and converted into grayscale using MATLAB R2021 software. The results show that the correlation value of R channel and grayscale has the highest value with R2 = 0.9569. This correlation is expected to be an initial study and suitable alternative for automating the assessment of the condition of oil palm FFB.

Abstract

Bioflapon is a construction material developed as an alternative to gypsum, widely used as ceiling panels. As the demand for gypsum continues to increase, other alternatives such as bioflapon need to be evaluated. This study assesses the environmental impacts of pilot-scale bioflapon production using a Life Cycle Assessment approach. The Life Cycle Impact Assessment is conducted using the CML method, focusing on four key impact categories: Global Warming Potential (GWP), acidification, eutrophication, and human toxicity. The bioflapon production consists of two main stages: transportation and processing. The processing includes pulverisation, mixing, and curing. It shows that transportation and curing are the major contributors to environmental impacts. Transportation has the highest contribution to GWP (0.94 kg CO₂ eq), acidification (5.5 × 10⁻³ kg SO₂ eq), and human toxicity (0.41 kg 1,4-dichlorobenzene eq), mainly due to fuel use and emissions. In contrast, eutrophication is dominated by the curing stage, with a value of 2.5 × 10⁻³ kg PO₄³⁻ eq, associated with high energy consumption. These findings indicate that efforts to reduce the environmental impacts of bioflapon production should focus on optimising transportation and improving energy efficiency during the curing process.
