The language and automata theory are which required course must implemented by college student in informatic engineering study program. In this course, there are finite state automata (FSA) and deterministic finite automata (DFA) which are important materials in language and automata theory. This material requires more understanding of mathematical logic from students to determine an input which can be accepted or rejected in an abstract machine system. The assist students  to understand the material, it is need to develop the learning media for mobile learning applications for language  and automata theory on finite state automata (FSA) and deterministic finite automata (DFA) based on android as an evaluation of learning media for students. And the development of this learning media use the ADDIE development model (analysis, design, development, implementation, evaluation) to  design language and automata theory applications learning so can be support the learning process for students and then assist lecturer to explain the material more dynamic and applicative.

Lingkungan sekolah merupakan wadah bagi siswa untuk menempuh Pendidikan. Dalam dunia pendidikan akan selalu memiliki berbagai kendala yang menyebabkan warga sekolah merasa tidak nyaman, diantaranya seperti kurangnya fasilitas yang dibutuhkan, terjadi hambatan atau kerusakan pada infrastruktur yang tidak kunjung diperbaiki karena ketidaktahuan petugas, adanya warga sekolah yang berkelakuan tidak baik seperti perbuatan guru yang kurang baik terhadap siswa dalam proses belajar mengajar yang menyebabkan siswa tidak nyaman dan takut untuk memberikan pengaduan, adanya siswa berkelakuan buruk yang dapat merugikan diri sendiri maupun orang lain, dan masih banyak lagi problematika yang berkaitan dengan pendidikan di lingkungan sekolah. Pada penelitian ini penulis membangun aplikasi berbasis website mengenai layanan pengaduan sekolah untuk memfasilitasi warga sekolah dan luar sekolah untuk dapat melakukan pengaduan atau pelaporan segala tindakan yang perlu disampaikan dengan tujuan dapat meminimalisir segala kekurangan dan kebutuhan yang ada yang berkaitan dengan sekolah dengan beberapa kategori diantaranya pelaporan yang berkaitan dengan Infrastruktur, keamanan, sarana, pelaporan tindakan negatif warga disekolah yang terlibat di dalamnya. Metode yang digunakan dalam membangun sistem ini menggunakan metode Extreme Programming. Penelitian ini menggunakan instrumen ISO/IEC 25010 dalam evaluasi aplikasi. Berdasarkan hasil yang diperoleh dari instrumen functional suitability sistem dikatakan baik karena hasil mendekati 1. Aplikasi juga dikatakan layak karena dapat memuat halaman di bawah 7 detik berdasarkan instrumen performance efficiency. Berdasarkan analisis Usability sitem memiliki kriteria Layak dengan nilai 93,8%, dari aspek reliability sistem memenuhi aspek dengan nilai ?95%. Dan memiliki grade A dalam instrumen Portaility

Medical science is a science that explores the handling of diseases carried out by health workers. The importance of the role of health workers today is based on data from the Ministry of Health, Indonesia still lacks health workers and it is hoped that a new generation will come who have broad knowledge, are intelligent, competitive and useful for public health. Basically, many prospective students who will enter medical education do not yet have knowledge about the use of medical devices, so education on the use of medical and medical devices needs to be carried out to provide insight to prospective health workers in the future. In this study, the author designed an application to provide education about medical devices commonly used in hospitals, both in terms of functions and how to use them for prospective students who are interested in majoring in health and medical sciences. The method in designing this system uses the Computer Assisted Instruction method. In its use, users can learn about medical and medical equipment according to their class, namely hospital health care and treatment, anesthesia equipment, teeth, eyes, ENT, radiology, cardiology, surgery, and several others. The author uses an expert review instrument in testing the validity and testing one to one to determine the practicality of using the application. Based on the results of the Expert Review, this application is declared valid based on the average value of the assessment results of media experts, design experts and evaluation experts with an average score of 4.0 so that this application category is declared valid. Furthermore, the results of the product practicality test through one to one testing were assessed by 3 respondents with an average value of 3.9 with practical criteria.
