Since revolution 4.0 and the outbreak of COVID 19, the world of education has been required to be able to transform from a face-to-face learning system to a distance learning system. Teachers have the flexibility of time to share scientific studies and provide independent assignments to students. In addition, teachers can also open discussion rooms for students online (Putri & Dewi, 2019). Independent learning is the readiness of individuals who are willing and able to learn on their own initiative , with or without the help of other parties in terms of determining learning objectives, learning methods, and evaluating learning outcomes. According to (Mujiman 2005 in (Aliyyah & Djuanda, 2020) the research was conducted using a descriptive quantitative approach. The subjects of this study were students majoring in Computer and Network Engineering, SMK Negeri 1 Ketapang class XII as many as 36 respondents. The results of the discussion show that the learning independence of students is lacking in indicators of not depending on others, discipline, responsibility, initiative and self-control it is proven that only indicators of self-confidence are in a good category Utilization of the application is felt to be less supportive because there are several billing assignments that are not known to have been collected or have not been collected or there is no system in place restrain students from being able to continue to the next material if there are assignments that have not been done. This is one of the declines in the percentage of independent learning. Until a positive value is obtained for future application development in order to increase the percentage of independent learning.

<em>The limitations of practice in the department become a dilemma in assessing students Computer Systems course in the Department of Computer and Network Engineering class X. Meanwhile In the realm of assessment there are values or skills. use Application Logic Circuit Designer (LCD) is one of the existing solutions. This app too can be installed (installed) on a Laptop or Personal Computer (PC). Whatever the purpose The use of this application in this research is so that students are able to carry out practicum in accordance with the material presented and develop skills without limit. To be able to increase the motivation of student learning outcomes on the Gate material Class X Logic majoring in Computer and Network Engineering (TKJ) at SMK Negeri 1 Ketapang. This research is a classroom action research consisting of 2 cycles, with the help of learning participation observation sheet from 36 students. Each cycle consists of planning, implementation, observation and reflection. results Based on research obtained from the use of Logic Circuit Designer (LCD) applications in learning must follow these steps that has been determined, namely starting from downloading the application, installing the application on a laptop or smartphone until how to use it.</em>
