Abstract-Technology has a great impact on human civilization. In order to bring the technology to meet its requirement, a system is developed. A system is a collection of elements or components that are organized for a common purpose. Through a system, technology is able to meet its requirements and benefit humans. In terms of crime investigation, previously, most of the crime investigation processes had been done manually. However, Asante (2013) had developed a simple application, which concerns the time of death estimation. However, this application was not a fully automatic system and was unable to give a proper contribution to the forensic science field and the time of death estimation. Thus, the Post-Mortem Interval Estimation System (e-PMI) was developed to assist in estimating the time of death by considering rectum temperature, ambient temperature, weight of corpse, layer of corpse's clothes, condition of corpse, and the condition of air and water. This system is expected to become the base system in estimating the time of death in order to produce a more reliable and better result.Index Terms-Technology, system, time of death. I. INTRODUCTIONTechnology refers to the core knowledge dedicated to create tools, unfolding the actions, and drawing out materials. In fact, technology can be described as products, processes, or even organizations. It is purposely designed to extend human abilities, which is the most significant part in any technological system. Thus, human abilities can accomplish even greater achievements, which then raise the credibility of humans. Technology also represents an application of science in solving problems. It assists in solving problems in communication, transportation, learning, manufacturing, creating artifacts, securing data, scaling businesses, and so on. A well-applied technology could benefit humans and create a new economic environment. The advancement of technology raises the information age which provides different work environment for highly competitive demands especially in business and in accomplishing various tasks [1].According to Ackerley [2], a system is a collection of elements or components that are organized for a common purpose. A system is a type of technology, which is developed to assist in human life. With an efficient system, many works that have been done manually can now be done automatically with less time consumed. Thus, a system imparts an outstanding benefit towards humans. Science is also related to crime observation. The field is known as forensic science. Forensic science is any science used for the purpose of law, which also provides impartial scientific evidence for use in the courts of law such as in criminal investigation and trial [3]. Forensic science is also an application of broad spectrum of science and technology that helps in investigations or in establishing facts of interest in relation to crime investigation or civil law [4]. In other words, forensic science is a legal way of investigating a crime scene as the source of information...
