After 3 years of development, the first trial was started on September 2009 in 6 sub-districts in Indonesia, including South Padang (Padang), West Denpasar (Denpasar), Tamalanrea (Makassar), Gondokusuman (Yogyakarta), Duku Puntang (Cirebon), and Jembrana Negara. It is planned that every Indonesia citizen will already have e-ID by the end of year 2012. If the plan is successful, then the next election in 2014 will be the first election using e-ID (e-Voting), which means, a brand new election system/procedure must be designed to maximize the use of e-ID. This book talks about how it should be implemented and how it would bring benefits for Indonesia.

By using User Experience Questionnaire (UEQ), this research is to evaluat e which aspect of mobile application is looked for by its u ser. Survey is conducted to 60 people to answer what experience they have on old application, new application and user expectation for application and compare them. The result shows that there s mu ch improvement from old application to new application, and for expectation user towards new and old application, the gap between new app to expectation become closer if compare with old app to expectation

Therefore, this is the reason for this platform to choose the beauty industry as a business sector. Besides being a business opportunity, the purpose of this research is to create a business model suitable for beauty service providers to improve their current business in the form of platforms and this platform is also a new media to promote the services they offer. In addition, this platform will provide an opportunity for beauty consumers to be able to find beauty products, beauty services, and book the beauty services they want. Qualitative method is used to gather data from beauty care providers and consumers. After platform testing, feedback gathering will be carried out using a qualitative method for beauty care providers and quantitative methods for consumers. This study also analyses the correlation between customer sa...

This paper hopes to show the comparison that can be made between the two kinds of databases on different platforms to see which one is truly better for data storage and removal for the Covid-19 pandemic, inspired by many countries attempts at creating tracing apps to reduce infections of the Novel Coronavirus.

This application relies on community participation to share location data with each other while traveling so that contact history tracing with COVID-19 victims can be carried out. However because COVID-19 is a recent virus, the application is also relatively new, which leads to frequent bugs like unable to load data, data is not saved, long response time, some features only work on android while in IOS it's not working, and the list goes on.

UI and UX is a very important part of mobile application design as it affects how easy it is for users to use the application, and also how easy it is to understand the application. Especially in the case of designing a mobile app for the currently ongoing pandemic that everyone has to use in a day-today basis to enter public areas around the country, such as malls, supermarkets, and others.

It has become a powerful way to store data in a specialized format that yields fast performance for a large amount of data. NoSQL databases are designed for modern web-scale databases. Although, nowadays, it is used to handle big data and many real-time web applications. They can handle enormous amount of unstructured data and structured data. As a result, developers will be able to be more nimble. NoSQL database developers, for example, may deploy code updates more quickly than relational database developers. However, security remains a very difficult issue even with NoSQL databases, as the security concerns inherent in previous databases have not been resolved in NoSQL. The most common example is that their password storage mechanism is weak, meaning it can be decrypted easily. This means that NoSQL databases have weaknesses and one of them is authentication weakness. This paper evaluates how strong the authentication aspect towards different kinds of attacks on a NoSQL database.

government, and many more. However, every system will always have flaws inside which is usually known as its weakness.
One of the weaknesses that existed inside MongoDB is related to the security inside the database such as the encryption.
MongoDB does not have any encryption which means that the database inside will not be secure. Every database should be
able to encrypt the data inside for the purpose of security. If not, attacks like data breach will reach the database and all data
will be leaked. With this research paper that aims to increase the security in MongoDB by using Percona Server, it is certain
that security inside the database could be implemented for further use inside the MongoDB database

MICE is important for seeing the visitors at a different angle, such as having an insight on the most visited booth of the event, how long the visitors spend time in one booth, and so on. The need of an application on this research for tracking visitors will be high especially during this Covid-19 pandemic. Therefore, to support the Indonesia economy recovery for years to come, especially on the MICE, a visitor tracking application is developed and tested. The purpose of this research is to develop algorithm for measuring the distance between visitors and the visitor density of a certain area in real time. This algorithm is implemented in the MICE event’s visitor mobile tracking application which uses Internet of Things (IoT) and Big Data Analytics as their foundation to embrace the n...
