Education systems in schools today are generally still oriented to the material media books and verbal material delivery by the teacher. This problem raises the lack of understanding and lack of interest of students in understanding material, especially in Biology chapter Genetics. The learning media provided by the teacher are felt to be lacking to support the achievement of maximum student learning achievement. Therefore an interesting learning media is needed that aims to foster students 'interest in learning and increase students' understanding of genetic material. Alternative learning media that can be used is with educational games. In the process of developing this educational game using the  waterfall method. The selection of the waterfall method is because the process of making each stage is systematic, meaning that each stage is interrelated so that it can facilitate the making of the system. The results of this study were in the form of an educational game "The Adventure of Cali-Cali" which was tested on students to find out the improvement in learning achievement. From the data obtained at the pretest results show that students still do not understand the genetic material provided by the teacher. This is evidenced by as many as 90.3% of students who have not met the  Minimum Completion Criteria (KKM). Then the treatment game was given when the posttest showed that as much as 6.50% of students did not meet the KKM. The comparison of the results of the pretest and posttest showed an increase in student learning achievement which increased to 83.8%.

In this era of digital optimization, Information and Communication Technology is growing very rapidly. This is in line with the demands and human needs that have been actualized in various fields, such as knowledge and education. To support a learning process based on SCIENCE (Science and Technology) required several supporting aspects such as online dictionary that includes vocabulary and functions of words / terms in the FIELD of IT. One of the supporting aspects is an alternative tool in the form of media that facilitates every community in learning the terms in the field of informatics. According to pie chart data from questionnaires that the authors made, as much as 50 percent of the knowledge of the term informatics of the general public (lay people) can be said to be still very low. In contrast to the academic community such as IT Lecturers and IT Students who do master the field, although it does not close the possibility there are some IT Students who do not fully understand in their fields. The expected result of the authors in this study is the increasing knowledge, especially the general public (lay people) in studying science in the field of IT especially language and informatics terms through online disses. This Online Dictionary application will be designed website-based using sequential search method where sequential search (also called linear search) is the most simple search model performed on a data set. The Online Dictionary application will run by searching for vocabulary or terms in informatics according to the keywords they are looking for, making it easier for users to learn the language of informatics. Keywords: Website, Vocabulary, Dictionary Online, Informatics, IT, Sequential Search, Science and Technology
