Gastric disease is a disease that cannot be underestimated, because if left unchecked it can result in other diseases appearing and can also cause death if not treated immediately. Diseases of the stomach can be caused by an inappropriate diet, a burden on the mind and also infections caused by bacteria. The little public knowledge of the early symptoms of gastric disease is the author's background to create a system that helps the public in obtaining information, consultation or initial treatment for gastric diseases without having to meet in person. The ability of an expert who can diagnose stomach diseases can be implemented into an application system. The methodology used in making the Gastric Disease Diagnosis Expert System Website is waterfall, namely analysis, design, implementation and testing. The testing phase focuses on the functional specifications of the program. In this Expert System, it uses the Forward Chaining method as reasoning and the Certainty Factor method to calculate the results of the yield trust. Hasil testing shows that this website can perform its function to diagnose gastric diseases. The test results are obtained from the inputs made by visitors by selecting the options that have been given and then will get the test results.

Announcement is a form of delivering information addressed to the general public. Announcement is a letter addressed to several people, agencies, or other parties whose names are too many to mention one by one. In the announcement in the Department of Informatics, University of Palangka Raya, it still uses a manual system. In a way that is still manual, it takes a lot of time in the process. Like what students have to do, they have to come check the latest announcements, and see new announcements through Whatsapp groups and Telegram groups. Therefore, with this problem, in the process of solving it, an Announcement Bot was made at the Department of Informatics, University of Palangka Raya on the Telegram Application which can complete the completion of finding the latest information by students. The stages of modeling the Announcement Bot in the Department of Informatics, University of Palangka Raya in the Telegram Application using the waterfall research methodology. Where, this methodology has several stages, namely, requirements definition, system and software design, implementation and unit testing, integration and system testing and operation. This Announcement Bot uses the Long Polling method. Where, this method the server will periodically check to the bot whether there is an incoming message. If there is an incoming message, the server will execute based on the request message sent by the user. Testing this system uses a User Acceptance Testing (UAT) testing system. The test results will be used as evidence that the software has been received and has met the requested requirements. This research produces an Announcement Bot at the Department of Informatics, University of Palangka Raya on the Telegram Application that can help find information in the Department for Students.

Augmented Reality is an environment that incorporates 3D virtual objects into the real environment in real-time. This study aims to develop applications for handicrafts typical of Central Kalimantan based on Unity 3D. With this application, it is hoped that it can be useful to help elementary school students to get to know handicrafts in Central Kalimantan which has been almost extinct. And the purpose of this application is so that students can learn more interactively using the Android platform without having to go to a place for making or selling handicrafts typical of Central Kalimantan.Making this application is built using Unity, Blender, and Figma Web. The methodology used in making this application for introducing handicrafts typical of Central Kalimantan is the Multimedia Development Life Cycle (MDLC), namely Concept, Design, Material Collecting, Assembly, Testing and Distribution. Design the design with UML. This thesis incorporates AR technology into handicraft applications typical of Central Kalimantan, so that this handicraft application becomes more real with the presence of 3D objects in handicrafts. Then this application will track and detect the marker, if the marker is detected correctly it will open an image of a 3D handicraft object and an audio explanation. The results of this study indicate that the Unity 3D-based learning evaluation media is feasible to be used as a learning medium in the arts. This is evidenced by the positive assessment of material experts and media experts. The results of the study were also strengthened by the assessment of the students in the agree category from the 15 respondents. Meanwhile , in the calculation of the calculation scale model , the respondent 's answer score is 345. Meanwhile, in the Likert scale calculation, the percentage is 92%. Based on these data, it can be concluded that the Unity 3D-based learning application is feasible to be used as an evaluation medium for elementary school art learning.

This method is still considered inadequate for reaching a wider market, especially among young people. So Joca felt the need to replace their old marketing concept with the concept of online food ordering (e-catering). This research aims to build a website-based e-catering application that is able to become Joca Catering's marketing and sales medium. The development methodology used in making this website application is the waterfall development method. The result of this study is a website-based e-catering application that can provide information for visitors and customers about the food menu provided and can be used to order food menus.

The development of information technology in the field of education, especially in the SKB (Study of Learning Activities) in the city of Palangka Raya requires e-learning applications to increase the effectiveness and flexibility of learning, because in this Learning Activity Studio it is still conventional, namely the learning process is still by teaching between students with This can only be done with the condition that there is a meeting between students and teachers in the classroom. This school is included in non-formal education which has the aim of replacing, adding to, and complementing formal education.The development method used by the author is the waterfall method in conducting this research. The waterfall method is a method that uses a systematic and sequential approach starting from the level of defining system requirements to maintenance. Where the waterfall method has 6 phases, namely Requirement Specification, Architectural Design, Coding, Integration & Testing, Operation & Maintenance.The results achieved are the availability of applications to support teaching and learning activities that can be obtained without being bound by time and place. The conclusion with this web-based e-learning is that it facilitates teacher and student communication, provides material, facilitates assignment and collection of assignments, and facilitates value information.
