The curriculum requirement requires the lecturer to be creative in developing the learning style. However, in interpersonal skill subject, the lecturer only provides things that available on the textbook conventionally and focusing on the material accomplishment of the curriculum without considering the learning expected output. To resolve that problem, the lecturer needs to modify the learning style by providing a learning innovation. One of the alternatives is implementing game-based learning model by playing media card. Therefore, the research objective was to describe positive effect of game-based learning model towards collegian’s learning motivation and achievement in Interpersonal Skill subject in STMIK STIKOM Indonesia. The research method used was Quasi-Experiment with non-equivalent control group design. The research instrument used was a motivation questionnaire and learning achievement test. The research result showed that there was a positive effect of game-based learning model towards Collegian’s motivation and learning achievement in Interpersonal Skill subject.

A Flooding is a disaster that often occurs in the Semarang area, especially on Jl. Raya Kaligawe. Flooding can occur due to the ineffectiveness of the pump work in a water impregnation pool. The impact of the floods is detrimental to students because with the flooding it can interfere with teaching and learning activities and studying student activities when on campus. At Sultan Agung Islamic University, Semarang has a water impregnation pool that is still manually controlled. By using Fuzzy Tsukamoto as artificial intelligence on Internet of Things technology, we can carry out intelligent control systems in water absorption pool pumps in realtime, so as to prevent and reduce human error that causes flooding. In principle, the Internet of Things works using a microcontroller, one of the microcontrollers that can be used, namely Wemos D1 mini. Wemos D1 mini is connected with an ultrasonic sensor to measure water level in a water infiltration pond, air temperature and air humidity sensor to detect rain.

Archiving in University that have not been well organized will cause a problems, the documents need for structuring and archives properly in the systems for the good standard a universities. The most importance of ease in finding the required archives is an important reason why it is necessary to develop an archive search system that can facilitate and improve the process of searching the archived document. Apllying cosine similarity algorithm in Information Systems is a solution for University to organizing archived documents, results from this reserach is the systems can show the relavant document from database list with precision 88.8% and recall 76.1%   from all the data in database.
