A home-made and low-cost basic logic kit equipped with lecture notes has been developed. The main purpose of developing this kit is to support undergraduate students in learning basic digital system, which is delivered in the digital electronics topic of Basic Electronics-2 course, at Physics Department, Surabaya State University. This kit consists of input switches, output indicators, a battery, and several logic gates, i.e. AND, OR, INVERTER, NAND, NOR, XOR, XNOR, which are assembled on a matrix board and plywood. The kit, which was packed in a plastic box and its front panel was made from a glossy photo paper, is simply portable to be used in classroom and laboratory. The lecture notes contain of digital system principle with emphasis on practical experiments and applications. The kit and the lecture notes were composed so that students easily understand those using provided examples to conduct experiments of digital logic. They were developed using a 4-D model that includes define, design, develop, and disseminate. The usefulness of the kit and the readability of the lecture notes were evaluated by distributing a questionnaire to 20 students taking the course. It was found that the students give the score of 4.6, 4.15, 4.03, 4 out of 5 for content, language, helpful for understanding basic logic, and layout, respectively, which indicate that the kit and the lecture, notes is advantageous tools in achieving better understanding of basic digital system.
