- Description: Abstract: Coconuts are very popular fruits worldwide. They have a variety of uses, health, and nutritional benefits. The uses of coconuts range from cooking and nutrition, skin health, cancer prevention, beauty products, charcoal with a coconut shell. The coconut scraping machines that are commercialized aren’t fully automated and require human hands. Scraping coconut is a laborious and time-consuming process. The manual process requires the operator to both rotate and apply human effort to scrape the meat portion of the coconut. The semi-automated process, on the other hand, requires the operator to hold the coconut half-shell against a rotary blade that rotates usually using an electric motor. Both ways, the operator is presented with dangerous forms of hazards. In this paper, an automated coconut scraping machine has been developed to solve a well know challenge regarding grating coconuts. The design proposed in this study will eliminate virtually all hazards related to coconut scrapers. It is a fully automated machine that takes both risks and effort from the operator. The system incorporates an adjustable blade that allows the movements according to two axes. A clamping mechanism that moves in the third direction allows a three-dimensional movement. The mounting of the coconut half shell in the clamp is set to take no more than fifteen seconds. Upon mounting, at a push of a start button, the scraping of the coconut is to be completely autonomous. Details of the designing and the development of the working model constitute the main contributions of this paper.

- Description: Abstract: In this paper, we highlight the effects of contaminated water on humans as well as the crisis of water supply and distribution of potable water in many areas of developing countries. Water is the most important substance on earth. While water is a primary human need, contaminated water can cause and spread diseases. It is, therefore, necessary to ensure that water is purified and decontaminated for daily use at a low-cost. Therefore, the design of solar-powered water purification systems is considered to produce clean water. Solar energy poses no polluting effect; thus, has become a dependable energy source for usage. The design of a solar-powered water purification system is based totally on the thermal method by using the thermal heating system principle. This principle converts sunlight rays into heat. The most vital aspect is the absorption of heat to induce evaporation of water. Research shows that flat plate collectors produce heat at relatively low temperatures (27°C to 60°C) and are commonly used to heat liquids. A solar-powered water purification system consists of a solar collector that absorbs sunlight to ensure vaporisation which is the first stage of purifying and a filter that removes contaminants. Four different concepts have been developed. A detailed description of the components and the operation of the systems constitute the main contribution of this paper.
