The Mexican sword (Aquarius palifolius) is an ornamental plant with attractive leaves and flowers. Besides being used as a potted ornamental plant, this plant is also widely used as an aquatic ornamental plant in aquariums because it can adapt to a watery environment. This research is a descriptive study by observing the morphological form of the Mexican sword (A. palifolius) planted in pots at the Green House of the Payakumbuh State Agricultural Polytechnic. The data obtained from the morphological characters of Mexican sword plants in roots, stems, leaves, and flowers were entered the table and analyzed descriptively. Then take photos as research documentation. The results showed that the characteristics of roots that have long soft fibers with white to cream-brown color have a little sap. Whole leaves Undersurface dull. Leaf-blade length 20–25.5 cm, width 16.5–22.5 cm. The surface of the stalk has nine ribs with a length of 29.3–47.7 cm, with a diameter of 6.6–9.8 mm. The midrib length is 8.5–11 cm and has a width of 2.3–2.5 cm. In one clump of plants, there are 9-10 leaves. The petals are 2.5 cm long and 2.6 cm wide. The stamens have 20 to 24 stamens. The filaments are light yellow to light green, and the anthers are yellow. The pistil is supers (above the base of the flower). The results the morphological characteristics of plants that are cultivated in the Harau area of Lima Puluh Kota district using certain pot sizes

Understanding science, especially physics, can not only be done with theory and formulation. It should relate the physics theory studied to everyday events. In addition, strengthening the characteristics of learning in madrasas can be done with an approach to religion (Qur'an science). The dichotomy occurring between science and religion makes them look like not interconnected. In fact, the Qur'an is the source of all sources of knowledge. The study of the integration between religion and physics presents a direction that can break the deadlock of physics problems. It is hoped to form an integration between religion and physics, which gives two understandings at once when learning. Examining the force and its relation to Newton's second law, also means examining the mass and acceleration. These quantities have a reciprocal relationship that can be peeled down in terms of religion and its relation to life. Mass can be analogous to the inertia (willingness) of a person to change his state, which is later also influenced by the quantity of the action (force) that a person will perform, and the determinant of the acceleration of his life (with a change in circumstances). Learning about force (F) will be closely related to acceleration and mass. A person with an enormous mass (m>>) will be more inert, because of which the acceleration he has will be smaller (a<<)
