Abstract

Heavy metals in waters are a threat to living things both biota that are in these waters, as well as on plants and humans that depend on these water sources. Water quality improvement can be done by utilizing local gravestone (Pilsbryoconcha exilis) as a natural filter. In this study consisted of four treatments and three replications. The amount of gravestone weights of 200 grams, 300 grams and 400 grams acts as a treatment that will later be seen its effect on water containing arsenic metal. The results of this study indicate that local gravestone can reduce arsenic levels in waters with a treatment weight of 400 grams showed the best results with the final result arsenic level of 0.0101 ppm and the highest daily growth rate is 200 grams of weight treatment with a market value of 4.40%.

Abstract

Plants, like other living things, need a combination of nutrients to live, grow and reproduce. Nutrients in plants can also be divided into two, namely mobile nutrients and immobile nutrients (non-moving nutrients). The condition of plants that are deficient or lacking in nutrients will experience growth disturbances and affect the yield of leaves or fruit. Leaf color can be a characteristic of plants under normal conditions or experiencing nutrient deficiencies. Deficiency of nutrients in plants will affect leaf shape, fruit production and plant age which results in stunted growth and rapid death of plants, in fruit production there will be loss of flowers or ovaries so that production will decrease. So far, plant maintenance has been done manually. Each plant is seen for later analysis of the results and it takes time to identify nutrient deficiencies. The aim of the study was to identify nutrient deficiencies in image-based chili plants based on the characteristics of the Red, Green, Blue (RGB) color and texture analysis using the Support Vector Model (SVM). The benefit of the research is to make machine learning-based applications to identify nutrient deficiencies which are divided into four classes, namely nitrogen (N) and phosphorus (P) deficiencies, P and potassium (K) deficiencies, N and K deficiencies, and chili leaves with normal class. .There are 120 plant data with an accuracy of 84.4%.
