Many factors could affect electricity distribution to seclusion places or the outer part of an island that needs electricity, for instance the power plant center is located very far away, low population, and difficult access to electricity. This is a design to establish a battery power generator that has the same concept with a common generator that could result in electricity power up to 36 kWh, this power can supply electricity to 30 houses with 1,2 kWh for each house. The goal of this research is to re-designing a generator by considering user needs. A survey had been made to acknowledge what customers might need from this product and axiomatic design is used to compile a parameter design using mapping process from customer attribute and functional requirement.

The employee management information system at Nazra Swim School (NSS) was created with the aim of improving the performance and service of employees at Nazra Swim School (NSS). Nazra Swim School has a lot of data, one of which is employee data that needs to be stored and processed. Employee data processing is currently still done manually. To facilitate the processing of employee data, an information system is needed to process employee data so that the resulting information is more accurate, efficient and precise. This employee management information system is done using the waterfall method. This information system design includes document flowcharts, system flowcharts, data flow diagrams, context diagrams, database design, conceptual data model (CDM), physical data model (PDM) and user interface design. The employee management information system is designed using the programming language PHP, Notepad++ and MySQL database. implementation of a web-based employee management information system can help administration and employees in managing employee data automatically.

Almost all aspects of human life have now been touched by tehnological advances, one of which is food recipes. In the past, when you wanted to learn food recipes, you had to go through magazines and newspaper. Then was a change, food recipes can be found on the website in the form of the text and images. Then it developed in to video broadcast on youtube, which can access via a computer or smartphone. This development in the culinery field is indeed very helpful, but it still has weaknees namely, the information contained on the websites and videos is only for one type of food, if you want to find another dish you have to search again, this method also requires quite a lot of time to find food recipes according to your wants and needs, and the food recipes you are looking for are easily lost and easily forgotten because they cannot be stored permanently. So that with the application Android-based tradisional Indonesian food recipes, it can be accsessed mobile by using a smartphone.So this is quite helpful for users to make it easier to find information about the materials needed to how make to make them. The approach used is an agile process approach with an extreme programming model, then the design uses UML (Unified Modeling Language).
