“…According to our results, the RGB colour analysis originating from IR thermal imaging reflects “pre-emptively” the orientation of the inner impairment of pea seeds caused by the hidden pest. Our results confirm the findings of Tuhid et al [ 22 ], who analysed RGB components stemming from plant surfaces in order to differentiate between orchids infected by phytopathogen, and their findings showed that the proposed method is capable of detecting the disease as well as some diseases categorised into different groups. The enzymatic processes involving heat production by the seed [ 23 ] as well as its differences caused by stressors could be detected by IR thermal imaging.…”

Pea (Pisum sativum L.) is an important leguminous plant worldwide, in which pests trigger significant damage every year. One of the most important pest is pea weevil (Bruchus pisorum, L) which causes covert damage in crops. In the present study, our aim was to obtain precise information pertaining to the extent and the nature of damage in pea caused by B. pisorum by means of non-invasive imaging methods. The infested pea samples were analysed by an infrared thermometer and a bioluminescence plant imaging system as well as a computer tomograph under laboratory conditions. The calculated weight of organic matter destroyed by the developing larvae was 36.46%. The changing of RGB (red, blue, green) codes obtained through thermal imaging and the CPS (counts per second) values originating from bioluminescence imaging in infested samples were statistically verifiable. According to our CT assay, the damage caused by B. pisorum changed the tissue density, volume and shape of the pea seeds by the end of the development of the pest. The results of thermal and bioluminescence imaging contribute to a better understanding of the internal chemical processes and the CT analysis helps to understand the alteration trends of the inner structure of seeds caused by this pest.

“…1). The standard deviation approach is generally influenced by the distribution of data values for each character of the R (red), G (Green), and (Blue) bands [15][16][17]. This approach was carried out by taking a logical approach to the calculation results of the statistical values and then grouping the selected vegetation type [17].…”

Aims: The study was carried out to assess the species composition, vegetation structure, regeneration and possible direction of vegetation development due to Acacia nilotica invasion. Study Design: The study applied the vegetation analysis and remote sensing technique in the deciduous forest of the Palu Valley in Central Sulawesi. Place and Duration of Study: The study was conducted in Biromuli District, Sigi Regency, Central Sulawesi Province of Indonesia in February 2019. Methodology: Species composition, vegetation structure and regeneration were studied using the split plot method, while the specific population and distribution of A. nilotica were studied using drone photos in an area of 10.24 ha. Results: Individuals >2cm in diameter are 24 species, 22 genera and 14 families. The main species are Tabernaemontana pandacaqui, A. nilotica and Jatropha gossypiifolia. The ground vegetation (diameter<2cm) contained 21 species, 21 genera and 17 families, dominated by Digitaria ciliaris and A. nilotica. The species diversity index is 2.3880 (moderate), while the species evenness index is 0.75 (unstable). Density of 1.069 individual’s per ha and total basal area 2.48 m2 per ha. The dominance of individuals with a diameter of 2.0-4.9 cm (62.9%), followed by diameter of 5.0-9.9 cm (32.4%), and diameter of 10 cm up (4.67%). The canopy layer consists of only one main layer at a height of 4-7m. Canopy analysis using drone photos showed that 27% of the total forest canopy area and 32.9% of the total individuals were controlled by A. nilotica. Conclusion: The dry forest in Sigi is the remnant deciduous forest located specifically in the Palu Valley which is still in the process of development. The invasion of A. nilotica needs to be controlled in a sustainable way so that the rest of the forest does not turn into a stretch of A. nilotica.

“…Successful control of siphoned water movement depends on receiving accurate real-time inlet and outlet flow rate of the water relayed by the sensors installed in the system and, most importantly, on instantaneous data acquisition from the fog server. 8 Moreover, aquaponics NFT system requires continuous flow of water. Hence, the monitoring and controlling of water flow is a very important aspect.…”

Objective: The article presents a discussion on the aquaponics technology, including its working principles and applications in farming as well as the trends and challenges associated with its use in different areas of agriculture. Methods/statistical analysis: In this work, we discuss aquaponics, a combination of two techniques: a. 'hydroponic', which means cultivating plants/vegetables without soil, and b. 'aquaculture', which means fish farming. Aquaponics has become a popular technique because of its similarities to natural ecosystem, where the only difference is that it is a controlled system, in which the fish eats and produce ammonia, beneficial bacteria convert ammonia produced by the fish into nutrients, and the plant absorbs the natural fertilizer and the nutrients. In addition, the water carrying the ammonia and nutrients is continuously recirculated through the system. Findings: The present study was conducted to explore and find a better way to apply the aquaponics agriculture system in various agriculture industries. Findings show that this method enhances the benefits and eliminates the many drawbacks that occur in traditional soil-based agriculture. Application/improvement: This agriculture system does not depend on the soil, and no pesticide is required during the farming. This system is suitable for year-round farming and can produce high-quality vegetables at a much higher yield rate. Vegetables grow at a much faster rate using this technique, compared traditional farming techniques. Aquaponics takes place in a closed system and there is no discharge of waste into the stream. This system produces up to 30% more production compared to traditional farming using the same amount of space. This system requires less water compared to traditional farming.
