Understanding computer system hardware is basic for the undergraduate student which study in the computer area. System user always needs a faster, cheap and reliable process which is conducted by it computer system self. To fulfill that process is required how a computer works from their design and how they operate. That course is conducted by Computer Architecture and Organization (CAO) course. Two computer undergraduate area which studies CAO is Computer Engineering (CE) and Computer Science (CS). To support great learning at CAO both CE and CS needs to not just study which has a material course but they had to practically study computer architecture and design by the simulator. Why simulator is chosen, because to create computer such as CPU, RAM etc. needs big systems that can manufacture them. Nowadays too much freely available simulator that can be downloaded and used anytime, but not all simulators meet study requirements and didn't meet the CAO Learning Outcome. CS and CE have an international curriculum that given by ACM Computing Curricula. So this paper is discussed what kind of simulator that meets Computing Curricula requirement to implement at learning process which helps the instructor to choose simulator that can be able to grasp knowledge that delivered to the student.

Computer Architecture consists of some basic design based on Computer Organization and Architecture (COA) such as logic design. Leading students to improve knowledge about COA needs a comprehensive learning with a working simulation of a simple 8-bit Central Processing Unit (CPU). The Design based on Von Neumann Architecture that generally includes Registers, Bus Interface, ALU, Memory and their structures. The CPU Architecture simulation used Logisim which capable to performs the digital logic simulation. Logisim has an ability to perform digital logic to build subcircuit become a larger circuit in a single environment from low-level combinational and sequential circuits to build a complete CPU. An undergraduate student has suffered to study COA with the theory that explained in several lessons, the lesson explained a structure and an architecture computer only. There are not providing a simulation that explained step by step computer architecture. This research to propose design and implementation 8-bit CPU (Central Processing Unit) architecture that designed and implemented step by step that created in Logisim and used the simplest design that is Mic-1. So the simulation easy to visualize then the Undergraduate Student can learn about the next competency which is to design and make a specific purpose computer.

The aim of this research is to design a smart medical device that is able to provide an initial diagnosis of lung condition based on body temperature and fingernail color. The presence of smart device is needed because the current lung examination is expensive and requires help from medical personnel. Due to the vital function of the lungs, it is necessary to check the lung condition which can be done independently, real-time and at an affordable cost. So if there is a problem in the lungs, it can be detected early and can be treated immediately before the disease becomes more serious. Based on the WHO, there are two lung diseases that cause millions of deaths, that is pneumonia and tuberculosis. The symptoms of both diseases can be known from the body temperature and fingernail color which indicates the oxygen levels in the blood. Temperature and color sensor was used to acquire data from these two parameters. Classification of lung condition based on the data from both sensors was designed using the Naïve Bayes method. There are three classification classes designed, healthy lung, pneumonia and TB. From the test result, the system provides an accuracy of 84.21% in classifying lung condition.
