The rapid development of technology generated a lot of instant messaging applications, as an example is LINE Messenger, Telegram, WhatsApp, Facebook Messenger, BlackBerry Messenger, etc. Many instant messaging applications cause some problems, one of which is the possibility of owning more than one instant messaging applications to meet messaging needs. This is very ineffective because messages will be received from various instant messaging applications and have to open all instant messaging applications one by one to reply to those messages. Application Programming Interface technology of instant messaging can be used to build a transport layer system that allows message exchange with several instant messaging applications using only one instant messaging application. The system built in this research requires a master instant messaging to be able to distribute messages to partner instant messaging, which in this case uses LINE Messenger as the master instant messaging to distribute messages to several partner instant messaging, which is Telegram and Extensible Messaging Presence Protocol.

Binary Log Design for One-Way Data Replication with ZeroMQ

Today, many business transactions are done online, especially in the financial sector or banking [1]. But as companies grow, many problems occur such as the inability to manage data consistency, especially when data is associated with more than one database. Replication is one of the most commonly used way of syncing data. However, to ensure data remains consistent, it is not enough just to take advantage of the replication process. The problem that often happens is connection failure or offline host. The Binary Log approach is one of the alternative methods that can be used to develop database synchronization. Generally, binary log is used for data recovery or backup purposes. Binary log in the DBMS (Database Management System) record all changes that occur in the database both at the data and structure level, as well as the duration of time used. This information can be used as a reference in updating data, while the ZeroMQ socket used as data exchange medium so data in all system locations will be synchronized and integrated in real time. This research will discuss how to develop a synchronization system by utilizing Binary Log from MySQL to recognize data changes, inherit changes, send changes, and hopefully can contribute new alternative method in developing real time database synchronization.

Internal Control Improvement for Creating Good Governance

Cooperative, which support the national economy of Indonesia, still has many problems. In 2015 the report by the Ministry of Cooperatives and SMEs shows many cooperatives are inactive because of having incompetence. Some issues such as the value of savings that do not fit between the cooperative and its customers, embezzlement of customer funds by parties who are not responsible, refunds troubled loans so that the cooperative suffered losses. These problems will be used as a critical point to do mapping with COBIT 5 framework. Based on the result of this mapping, it will be prepared internal control based on the framework of possible internal controls such as COBIT(Control Objective for Information & Related Technology), COSO(Committee of Sponsoring Organizations), ITIL(IT Infrastructure Library) and national regulations that are prevailing in Indonesia. Control is expected to discuss the internal problems that occurred in each business process that used in the cooperative.
