This research aims to design an applications of goods inventory system that uses barcode scanner on Android device. The desktop applications is based on Basic language and on for Android applications is developed using Java language. MySql database is store on online server, so that can be accessed by applications in Android mobile. The process of data exchange between Android and database is done by using web service to make distribution data easier.The result of making the application that is able to check the information status of goods stock availability via Android smartphone just by scanning the barcode listed on the goods. Indirectly this application can also increase the waiter’s service to the consumers.

Ilmu pengetahuan dan teknologi dalam bidang robotika pada saat ini berkembang dengan sangat cepat. Teknologi robotika pada dasarnya dikembangkan dengan tujuan untuk membantu manusia dalam melakukan pekerjaan tertentu, seperti pekerjaan yang berisiko tinggi, pekerjaan yang tidak bisa dikerjakan oleh tangan manusia secara langsung dan pekerjaan yang membutuhkan ketelitian tinggi. Pada saat ini, robot masih dikendalikan secara manual oleh manusia menggunakan Baterai sebagai sumber energi robot dan melakukan pengisian secara manual. Berdasarkan hal tersebut maka ada suatu keinginan untuk berkontribusi dalam pengembangan teknologi robot 6WD yaitu dengan merancang sebuah sistem Smart charging menggunakan Panel surya sebagai sumber energi untuk melakukan pengisian baterai robot secara langsung. Sistem yang dibuat, nantinya dapat membuat robot 6WD, bergerak dengan cara manual menggunakan inputan dari komputer yang dikontrol manual dari manusia. Manusia hanya perlu menggerakkan dan dapat melihat kondisi dari 2 buah baterai robot 6WD dari Komputer, kemudian komunikasi yang terjadi antara komputer dengan robot dapat dilakukan secara dua arah, agar robot dapat memberikan informasi balik kepada komputer, baik itu daya baterai, loss area dan lain sebagainya.Arduino Mega 2560 digunakan sebagai sistem utama yang mengolah semua data input dan output pada sistem. Modul HM-TRP befungsi untuk mengirimkan data dari robot ke komputer untuk ditampilkan.Pengiriman informasi robot 6WD meliputi informasi kondisi status 2 buah baterai, arus baterai, tegangan baterai, dan arah dari gerakan robot yang akan dikendalikan melalui GCS(Ground Control Station).   [TURNITIN CHECK 8%, 18042017]

With the number of existing data, would have difficulty in doing the classification and the classification of the existing data. To resolve the issue, one way to do clustering is with data mining using clustering technique. The purpose of this research is the importance of knowing the pattern of the production of an industry that can provide the decision and the construction of clustering patterns for development and industrial progress. The results of this research can provide recommendations to improve the development of industry, help the owners of industry to develop the industry to an increase in the number of production and product quality, improve the competitiveness of the owner of the industry in developing its products. In this research will use the K-Medoids algorithm for data grouping of the industry so that it will be found the information that can be used for the recommendations of the improvement of marketing. The results of clustering with the number of cluster 3 produces the first group contains 85 members, the second group contains 222 members and the third group numbered 3 members. The third group are classified as productive because it has a combination of the value of the production of the most high the results of clustering have the quality of purity worth 1 means good cluster quality.

Gastroenteritis is a disease that attacks the body's digestive system, especially in thesmall intestine and stomach through viruses and bacteria. In addition to its transmission causedvirus and bacteria, it can also caused by unhygienic food and drink. However, people generallyequate gastroenteritis with diarrheal disease, causing medical mismanagement that can befatal. Therefore, this research trying to build an Android based application that can help peoplein diagnose gastroenteritis. So in this research, the application was build using ClassificationAnd Regression Tree using an Android platform and flutter extension. This research usinghistorical data of 780 patients with 2 classes of disease, namely gastroenteritis and gastritis.The testing results is done to determine the peformance of application such as accuracy,precision , and recall of the application in diagnosing disease. According to confusion matrixtesting results, the application that was build able to diagnose gastroenteritis and gastritisdisease by obtaining an Accuracy of 85.1 %, Precision of 84 %, and Recall (applicationsensitivity in diagnosing) of 98 %.

Student motivation at class takes major role on achieving courses’ learning outcomes. Multimedia based content, game-based quiz, or self-assessment can maintain student interest to follow the learning process. Apart from the individual solution, working in group is one way to improve student motivation, however without proper arrangement, putting students in groups can degrade the competitive atmosphere of class, as less-smart students hang up to the more-smart students. Another alternative is implementing collaborative learning such as peer assessment that allows students to grade their fellows. However, objectivity between students must be concerned as students tend to give high-grade for their fellows. Combining group mode and peer assessment, this work proposed group peer assessment to improve student motivation on e-learning. Proposed method started by teacher open a group assignment on e-learning. Students then work on group to create solution. After the solutions are submitted, the extra-group peer assessment begins, where each group examines another group work. To maintain the objectivity of the peer assessment, final grade of each group obtained by combining grade from another group and grade from teacher.  In the meantime, cooperation atmosphere in each group is maintained by intra-group peer assessment, where each member asses all his/her teammates in terms of intra-personal and inter-personal skills.
