Obesity is a disease that is caused by the condition of a person's body that has a lot of fat in his body and is overweight or very fat. This condition is usually caused by the intake of calories into the human body that exceeds the capacity required by the body, where this condition causes a buildup of calories that turn into saturated fat. These conditions cause various chronic diseases such as diabetes, hypertension and coronary heart disease. Therefore, in order to avoid disease conditions caused by obesity, treatment and knowledge are needed so that it is not too late to take action so that the disease does not become severe. One of them uses an expert system, so that people can check for diseases without having to see a doctor. The method used Hybrid Case Base is used to make the best decision from a number of symptoms or alternatives from the diagnosed disease. The aim is to make it easier for the public to find out the diseases they suffer from obesity and be able to check them early. Where this expert system applies the Hybrid Case Base method which has the final result of this research producing an accurate diagnosis with a sample of symptom data used and getting a similarity measurement percentage of 77% with a diagnosis of the possibility of having Type 2 Diabetes.

alternative ways in determining trinomial coefficient with ladder multiplication and its construction in a cone. Ladder Multiplication perform by trinomial form factoring, then determine a factor as ladder and as ladder user. Every trinomial coefficient that we get will be constructed in a cone. Coefficient that constructed from a cone is another alternative aside from construction from Pascal's pyramid. Every cone's layer that have trinomial's coefficient shows power of that trinomial's coefficient. Such as third layer means that trinomial coefficient on power n = 3.

Game merupakan sebuah media pembelajaran yang menyenangkan, yang disukai oleh anak dan remaja saat sekarang ini.  Dengan mengembangkan game untuk pendidikan diharapkan dapat meningkatkan engagement siswa pada pelajaran yang ditawarkan. Oleh karena itu, perlu dibuat suatu pelatihan untuk mengembangkan kemampuan mahasiswa agar dapat membuat game edukasi yang meningkatkan kemampuan pemrogramannya. Melalui pembuatan game ini mahasiswa dapat berlatih memprogram dengan baik dalam bentuk logika game pada software game IDE bernama UNITY. Selain itu mahasiswa juga dapat meningkatkan kreatifitas dan keterampilan design game yang akan dibangunnya.
