This research shows that the use of SAVI-based learning multimedia can improve high school students’ understanding of concepts and learning motivation. However, this research was only conducted in certain high school schools. The research gap in this research is whether the use of SAVI learning multimedia can increase students' understanding of concepts and learning motivation. The type of re…
ABSTRACT Lithology interpretation in Gean de Green II Housing, Rimba Panjang Village, Tambang Sub-district, Kampar Regency has been measured using Schlumberger geoelectric method. This study aims to determine the lithology layer and aquifer layer that has the potential for fresh water. The measurements are carried out in two trajectories with a length of 300 meters. Based on data processing, t…
ABSTRACT Research on the biosynthesis of ZnO nanomaterials using pineapple extract and their antibacterial activity has been carried out. The aim of this research were to modify and characterize ZnO nanomaterials and its application as an E.Coli antibacterial. ZnO nanomaterials were formed through a biosynthesis process of Zn(NO3)2.6H2O as precursor with pineapple fruit extract acts as a biore…
ABSTRACT This research is to fabricate Dye Sensitized Solar Cell (DSSC) based on ZnO nanomaterials. One of the efforts to increase the efficiency of DSSC is by doping the ZnO active material. ZnO nanomaterial doped with Niobium 0 wt%; 2.5 wt% and 3.0 wt% is successfully synthesized using the hydrothermal method. The results of the synthesis are analyzed using UV-Vis absorption spectroscopi…
Learning media on Newton's Law material that has been developed by several researchers previously needs to be given more additions, including by using Smart Apps Creator technology. This research aims to develop learning media Smart Apps Creator Newton's Law that is valid, practical, and effective to be used as media in high school physics lessons that can increase learning motivation and …
The android-assisted experimental device on sound wave material has been developed by several researchers before it does not cover complete experiments such as linear doppler effect, rotational doppler effect, resonance and interference all at once. This study aims to develop a valid, practical and effective androidassisted sound wave experiment device for use in high school physics lessons…
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.
