When the selection of food ingredients is done inappropriately, the food maker can suffer losses because the ingredients chosen exceed the target for their use. Proper data collection in managing food ingredients is also needed by food makers in large quantities to produce delicious food as well. Universitas Advent Indonesia is a boarding campus which organizes and serves food for students on campus. Food serving for students is managed by the Cafeteria Department. One of the challenges that faced by this department is the collection of food ingredients on each food menu. Because of cooking in large portions, errors in the use of food ingredients are often found. In one meal, the cafeteria manager must prepare food for 1000-1500 servings. Then in one day the cafeteria must prepare food for 3000-4500 servings. Therefore, conducting this research aims at designing an information system that can record incoming materials, available materials and exit materials. This study also aims to make it easier for workers in the selection and data collection at the cafeteria of Universitas Advent Indonesia. The method that used in this study is SDLC (System Development Life Cycle), they are: (1) Analysis of Program requirements (Requirements). (2) Design (System Design). (3) Writing the Program Code (coding). (4) Program Testing (Testing). (5) Program Leading (implementation). Based on the design that has been described, it can be concluded that the system built can improve the performance of Universitas Advent Indonesia employees; the information system that is designed includes the selection of food ingredients as well as monitoring incoming, outgoing and available ingredients. The system built can also store data as desired. The design of this system is web-based, the use of this system will be even better if the design of this system is implemented mobile in the future.</em></p> Vember Ezer Sihotang Andrew Fernando Pakpahan Copyright (c) 2020 TeIKa http://creativecommons.org/licenses/by-sa/4.0 2020-10-30 2020-10-30 10 2 81 95 10.36342/teika.v10i2.2375 Design of Information Systems for Universitas Advent Indonesia Graduates https://jurnal.unai.edu/index.php/teika/article/view/2382 <p><em>The use of a technology is currently very widely used in the community.

The population for this study is all students enrolled both in the odd and even semester 2019/2020, i.e. 1516 students, and all population become sample. The academic achievement is seen solely by Semester Grade Point Average (GPA) achieved by the students in end of semester. Generally, at the university level, the academic achievement increased, although there are two faculties, i.e. Economics and Education, the academic achievement of students decreased slightly, while for other faculties, the achievement increased. Based on the batch, the first year student showed a negative impact of daring system, while other batches performed positively. In terms gender, both male and female students have a positive impact of daring learning system, however female students performed better than male students. These results are surprising, since it was assumed before that the academic achievement will be decreased due to the drastic change in the learning model from class room model to virtual model. This study implied that the covid-19 pandemic brought a positive impact in the academic achievement of UNAI students. This happened since both faculties and students of UNAI were successful to overcome any difficulties or challenges in the learning model due to the covid-19 pandemic However, this study needs to be continued to see the long term observation, whether the positive impact still happens or not in the odd semester 2020/2021.</p> Albinur Limbong Copyright (c) 2020 TeIKa http://creativecommons.org/licenses/by-sa/4.0 2020-10-30 2020-10-30 10 2 161 168 10.36342/teika.v10i2.2386 Design of Web Based 360 Virtual Reality Application at Universitas Advent Indonesia https://jurnal.unai.edu/index.php/teika/article/view/2383 <p><span lang="id">Today, many web applications are dynamic and interactive to be applied in Information Systems, Telecommunications, Trade, Banking, Education and various other types.

The marketing team sent randomly may not be able to achieve the expected target. In order to achieve the target, the placement of the appropriate marketing team will get more efficient results. Customer data that has been stored when a customer registers for check-in at Sutan Raja Hotel and Soreang Convention Center, can be utilized to create marketing support strategies that can be very useful for the Hotel. Data used in marketing strategy decision support include data from the customer's home city, gender, main segment, and duration of stay that is analyzed using the K-Means Clustering Algorithm so that the right customer cluster is known for the promotion approach. Data will be processed using Weka data processing software with K-Means Clustering Algorithm and K = 3 so that the data will produce three clusters. With the final result of Cluster 0 in Jakarta City, male gender, OTA segment play, and 1 day stay duration. Cluster 1, Jakarta City, male gender, individual segment play, and duration of stay for 3 days. Cluster 2 Bandung City, male gender, individual segment play, and duration of stay of 2 days.</span></p> Romiwita Irene Klarita Fergie Joanda Kaunang Copyright (c) 2020 TeIKa http://creativecommons.org/licenses/by-sa/4.0 2020-10-30 2020-10-30 10 2 107 115 10.36342/teika.v10i2.2380 DESIGN OF EXPERT IDENTIFICATION SYSTEM USING FORWARD CHAINING METHOD ON ANDROID https://jurnal.unai.edu/index.php/teika/article/view/2384 <p><span lang="IN">Goldfish are loved by ornamental goldfish enthusiasts in education and the general public. Goldfish in Indonesia, there are several types of popular goldfish that people often keep. As a layman, sometimes he is still confused about the types of goldfish he meets. The name of the type of goldfish in one area is usually different from the name in another area, even though it is from the same type of goldfish. This makes it difficult for fellow goldfish lovers or fish farmers who deal with goldfish as a business in the world of ornamental fish. It takes a goldfish expert who is experienced in identifying types of goldfish. In fact, the number of goldfish experts is very small, making it difficult to find at any time. The solution offered is by designing an expert system application that can identify types of goldfish based on android which can identify types of fish based on body shape, tail, eyes, head and color of the goldfish. This study uses the System Development Life Cycle (SDLC) method as an application design method, and the identification method uses forward chaining. The conclusion of this research is the application of identification of types of goldfish helps goldfish lovers in finding the type of goldfish correctly. Applications made produce an accuracy of 87.5% with a system inaccuracy of 12.5%. The suggestion from this research is that it is hoped that this application can be made and used by using the image recognizer on goldfish so that this application can be more easily used by goldfish lovers in identifying the type of goldfish desired in the future.</span></p> Andre Renaldy Sihombing Copyright (c) 2020 TeIKa http://creativecommons.org/licenses/by-sa/4.0 2020-10-30 2020-10-30 10 2 143 159 10.36342/teika.v10i2.2384 THE APPLICATION FOR PRIMARY SCHOOL STUDENT LEARNING USING MULTIMEDIA DEVELOPMENT METHOD LIFE CYCLE (MDLC) https://jurnal.unai.edu/index.php/teika/article/view/2381 <p><span lang="IN">Learning models using computer technology should be developed in the present.
