ABSTRACT Multispectral imaging has many applications in agriculture, such as prediction of the internal qualities of fruit and vegetables. Multispectral is preferable than Hyperspectral imaging for fast inline sorting and grading machine vision due to fewer wavelength bands applied. Oil palm fresh fruit bunches (FFBs) are the source of crude palm oil (CPO) in Indonesia and Malaysia. However, t…
ABSTRACT Sorting plastic covering is crucial before plastic waste has brought into landfill. Manual sorting doesn’t recognized due to limitation of human vision, subjective, and time consuming. Multispectral imaging has advantages for plastic waste classification, because it can cover only visible range of electromagnetic spectrum, but also infrared range (700 – 2500 nm). Plastic waste has…
ABSTRACT Plastic waste is one of environmental problem which needs immediate solution. The amount of plastic waste in Indonesia has reached 5.63 million tons per year or 17.1% of the total national waste in 2021. Waste segregation is still operated manually and traditionally. Digital waste segregation or separation using imaging methods is a potential method to obtain efficient and low cost re…
ABSTRACT Sorting and grading of oil palm fresh fruit bunches (FFBs) is essential in producing quality Crude Palm Oil (CPO). Multispectral imaging systems are a fast, non-destructive alternative to sorting because they use fewer wavelengths. This research aims to classify the maturity of oil palm FFBs using a multispectral imaging system. The multispectral imaging system consists of a filter wh…
ABSTRACT Multispectral imaging is a remote sensing method that only records the total intensity falling on each pixel. This method is also use to determine the ripeness of oil palm's fresh fruit bunches (FBB). The soil used for fresh fruit bunches of oil palm is mineral soils and peat soil FFB is the main source of crude palm oil (CPO), to obtain fruit with good quality. The sorting and gradin…
ABSTRACT Fresh Fruit Bunches (FFB) Oil Palm is a source of crude palm oil (CPO). The palm oil industry one of Indonesian commodities. The sustainability of this industry reguires technology development, especially in the automatic process of sorting and grading palm FFB for the quality of CPO. One of the sorting and grading parameters is to determine the percentage of Tenera's FFB compared to …
ABSTRACT Organic waste is still mixed with other types of waste in landfills. Waste segregation is important to process to facilitate the recycling process. Modern waste segregation method is required for less time and more effective than traditional methods. Modern waste segregation can be supported using computer vision. Computer vision consists of a combination of optical and non optical co…
ABSTRACT Waste is still a crucial problems faced by global society daily. It requires further waste management. The waste sorting system has implemented an imaging method for a plastic and organic waste sorting system that is effective in identifying and distinguishing waste based on color or chemical substances. Waste segregation is important to facilitate the recycling process of polyethylen…
ABSTRACT Electrical and physical properties of soil can be used as indicators to measure soil conditions in agriculture because of their fast and efficient measurements. One method developing agricultural applications to understand on land conditions by measuring the value of electrical conductivity and water content. The land investigated is peatland in Teluk Meranti Village, Riau. Measuremen…
The main problem of Science learning was caused by the low absorption of students in cognitive abilities, as seen from the students’ low learning outcomes. Depending on this condition, the results showed that the responses of students were passive and got difficulties to solve problems in their learning, where the teachers still used the lecturing method as a learning resource. The Discovery …
SOLE E-Module, is a teaching material developed using Canva media on light material that produces modules in digital form used for independent learning. This E-Module is prepared with the SOLE (Self Orgenized Learning Enviroment) learning model The purpose of this study is to design and test the validity of E-Module learning media based on the Self Organized Learning Environments (SOLE) le…
Science learning is learning that requires a high level of conceptual understanding and good skills. Conceptual understanding will increase if there is the application of appropriate learning models and media. But the learning results show that students have a low understanding of the concept. Efforts to increase student understanding of concepts can be applied through innovative learning, name…
