“…It is a combination of several technologies such as global positioning system (GPS), remote sensing (RS) technology, geographic information system (GIS), and physical sensors that collect data of growth traits and yield of fields and carries out various kinds of management (Lin et al, 2019). For example, Roslan et al (2013) used microwave and machine vision application as the rapid detection method in determining the surface of Dioscorea hispida rhizome alkaloid content. They found that the method can be used to visualise the colours on the D.hispida rhizome peel.…”

Weed infestation happens when there is intense competition between rice and weeds for light, nutrients and water. These conditions need to be monitored and controlled to lower the growth of weeds as they affected crops production. The characteristics of weeds and rice are challenging to differentiate macroscopically. However, information can be acquired using a spectral signature graph. Hence, this study emphasises using the spectral signature of weed species and rice in a rice field. The study aims to generate a spectral signature graph of weeds in rice fields and develop a mobile application for the spectral signature of weeds. Six weeds were identified in Ladang Merdeka using Fieldspec HandHeld 2 Spectroradiometer. All the spectral signatures were stored in a spectral database using Apps Master Builder, viewed using smartphones. The results from the spectral signature graph show that the jungle rice (Echinochloa spp.) has the highest near-infrared (NIR) reflectance. In contrast, the saromacca grass (Ischaemum rugosum) shows the lowest NIR reflectance. Then, the first derivative (FD) analysis was run to visualise the separation of each species, and the 710 nm to 750 nm region shows the highest separation. It shows that the weed species can be identified using spectral signature by FD analysis with accurate separation. The mobile application was developed to provide information about the weeds and control methods to the users. Users can access information regarding weeds and take action based on the recommendations of the mobile application.

The high concentration of cyanide in Dioscorea hispida dennst should be reduced through immersion in seawater and interaction with rubbing ash. Soaking seawater prepared in immersion time 12, 24, and 36 hours accompanied by the replacement of seawater every three hours, while interaction with rubbing ash was ready with 75% and 100% concentration of ash on 12, 24, and 36 hours of storage time respectively. Measurement of cyanide concentrations of Dioscorea hispida dennst samples was prepared by argentometry titration with Liebig method after through the steam distillation process. Based on the results of this study, it found that immersion time for 12, 24, and 36 hours could reduce cyanide concentrations about 48.30%, 64.44%, and 70.88%, respectively. The interaction by using 75% rubbing ash for 12, 24, and 36 hours, it can reduce 24.09%, 38.69%, and 51.42% cyanide concentration in Dioscorea hispida dennst tubers, respectively. The Dioscorea hispida dennst tubers smeared with100% rubbing ash for 12, 24, and 36 hours. It can reduce cyanide content in Dioscorea hispida dennst by 36.26%, 49.92%, and 59.63%, respectively. Further treatment with drying and fermentation produces Dioscorea hispida dennst with a lower concentration of cyanide about 88.68% with a soft and white texture.
