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…
Mengingat pentingnya Ilmu Pengetahuan Alam dalam berbagai bidang kehidupan manusia, maka perlu diperhatikan mutu pengajaran mata pelajaran Ilmu Pengetahuan Alam yang diajarkan di tiap jenjang dan jenis pendidikan. Masalah utama pembelajaran yang masih banyak ditemui adalah tentang rendahnya hasil belajar peserta didik. Rendahnya hasil belajar Fisika siswa disebabkan oleh banyak hal antara lain:…
The purpose of this research is to develop test instruments based on aspects of scientific literacy indicators. The type of research used is Research and Development (R&D) research using the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) development model. Validation was carried out by 3 expert lecturers, all assessment indicators for each feasibility aspect were declared…
This study aims to describe the Improvement of Students' Cognitive Learning Outcomes after applying the Problem Solving Learning Model with a Contextual Approach and to compare it with Conventional Learning which is applied in Class VIII of SMP Negeri 11 Pekanbaru. This research uses Intact Group Comparison research. The population in this study included all eighth grade students of SMP Ne…
ABSTRACT Every year oil palm fresh fruit bunches (FFB) production continues to increase. However, one of the problems in crude palm oil (CPO) production is the process of sorting and grading, which is still done manually and traditionally. This problem can be eased by introducing a computer vision-based sorting and grading system and you only look once (YOLO) object detection method. This stud…
ABSTRACT Clothing is one of the most basic human needs that cannot be ignored. Clothes can be washed and dried several times. However, drying clothes is not possible during the rainy season and after sunset. This research aims to create a new clothes dryer made from coconut shell waste using a digital system and a heat source from burning biomass which can be used at night or when it rains. Te…
ABSTRACT The purpose of this study is to determine the magnetic properties expressed in the hysteresis loop as well as the morphology of Iron sand Iron Oxide nanoparticles of Logas Village, natural sand, which are doped with Chromium. The separation between magnetic and non-magnetic particles is investigated using the strong magnet Neodymium Iron Boron (NdFeB). Magnetic nanoparticle preparatio…

ABSTRACT The main problem of cassava farmers is post-harvest processing, which is the drying process. The drying process is required to process cassava into Gaplek, done using sunlight or a cabinet dryer based on coconut shell biomass. The cabinet dryer is usually operated manually; therefore, an instrument is purposed to measure Gaplek moisture content, temperature, and humidity in the cabine…
ABSTRACT Noise is a major issue for people who live near roads or other noisy places. Sound absorbers are a good solution to this problem. This study aims to determine the absorption coefficient of the acoustic wall with a composition of palm fronds with a thickness of 3 cm and varying frond mass of 0.1 kg, 0.15 kg and 0.2 kg. This research used an impedance tube and the transfer function appr…
