The Problem-And It’s Background
Potato as an alternative battery for scientific calculator is the chosen topic of the researchers. The researchers thought of many topics but the topic about the scientific calculator get their attention. They thought that scientific calculator is very useful to students especially to 4th year students.
A scientific calculator is a type of electronic calculator, designed to calculate problems in science, engineering, and mathematics. They have almost completely replaced slide rules in almost all traditional applications, and are widely used in both education and professional settings. In certain contexts such as higher education, scientific calculators have been superseded by graphing calculators, which offer a superset of scientific calculator functionality along with the ability to graph input data and write and store programs for the device. There is also some overlap with the financial calculator market.1
The first scientific calculator with basic functions was released in 1968. And in February 1, 1972 Pocket Calculator and the world’s first hand-held scientific calculator was released by Hewlett-Packard. Until now many brands like Casio and Sharp were releasing new models of scientific calculator with more hi-tech program.
The researchers thought that the battery of scientific calculator is hard to find. It cannot be found in an ordinary market. They thought what if the user of scientific calculator runs out of battery? What if they can’t find a battery for it? What can be an alternative battery for it? The researchers want to prove and study that potato can be an alternative battery for a scientific calculator. Potato can produce and convert energy and it can be use in a scientific calculator. The researchers thought that potato can be used by the students and users of scientific calculator because it can be found easily in the market.
