The Problem
Background of the Study A leaf is a lateral photosynthetic appendage of the stem of a plant, commonly broad, flat, thin and of a green color. Leaves (plural) are the “food factories of plants, the sites where most of the plant’s energy is produced [1]. There are leaves that provide a protective service when a plant is under attack. Leaves may also serve as a storage sites or help obtain food for a plant [2]. For plants, as defense, leaves protect them from enemies such as animals, diseases, and environmental extremes through specific defense mechanism [3]. The most important contributions leaves make to our planet’s ecosystem are through their processing of oxygen and carbon dioxide. Oxygen, though a waste product of photosynthesis is essential to plant, animal, and human survival. As leaves break down carbon dioxide and release oxygen, they also help determine global climate patterns [4]. On the other side, a block is a molded rectangular brick of clay or sand enclosed in a molder and hardened for long hours and used as a building and paving material. Bricks were often used for reasons of speed and economy [5]. The researchers aimed to make dry leaves into use not only by preserving it and use as decorations but by making it as one of the main component for concrete blocks. Also, to support the RA 9003 or known as Ecological Solid Waste Management Act for implement.
Objectives of the Study This study primarily aims to make dry leaves as one of the main component in making concrete
