Nutrient Analysis of Plant Mantangan and it is Potential as the Organic Fertilizer in Supporting Plant Physiology Courses

Plant physiology is one of the subjects in higher education, where the material and the subjects studied in this course is implemented in daily life related to human needs thathave the opportunity to be developed into business capital by modifying it according to needs, because the nutrient content and the secondary metabolites possessed by green plants studied in plant physiology courses are very useful for the growth and development of the plant itself. Plant of Mantangan (Merremia peltata (L) Merril.) is a plant that is classified as an Invasive Allien Species which grows and develops well although it is not in its natural ecosystem. The effort to prevent Mantangan at this time is still very minimal so that it is necessary to find the right way to anticipate the speed of growth and development of these plants such as by utilizing these invasive plants as ingredients for organic fertilizer for plants. Plants that are considered detrimental such as Mantangan turned out to have great potential to be used again as ingredients that have value and are very useful for human life. This research was conducted to analyze the nutrient content of the plant Mantangan (Merremia peltata (L) Merr.) and its potential as organic fertilizer in supporting the subject of plant physiology. The study was conducted at the Laboratory of the Agricultural Technology Study Center in East Kalimantan from March 27 to May 19, 2018.The results of the study show that the leaves, stems and flowers of the plants of Mantangan have the potential to be used as organic fertilizer. This can be seen from the nutrient content of Mantangan leaves, namely 10.25 water content, 44.87 C-organic, 1.68 N total, P 0.15, and 5.14 K. Stems of Mantangan have a water content of 15.18, C-Organic 42.91, N Total 1.19, P 0.18, K 2.54. Mantangan Flowers have 15.78, C-organic 39.35, N total 1.58, and K 2.11. The potential of the plant as an organic fertilizer can support plant physiology courses because the procedure for making organic fertilizer is contained in a Student Activity Sheet which can be done by students themselves.
