1. Basic Concept of Information and system
Information System Concept

2. System System Approach : Procedure Element
A network of procedures in sequence of linked activities, gather together to achieve certain goals
Element
Set of interrelated components working together to achieve a particular goal

3. System Goals
The purpose of a system is to achieve a goal or to reach objectives. Goal covers a wide scope, while objectives covering a narrow scope

4. System Classification
Abstract Systems & Physical Systems System Abstract: The system of thought / ideas that do not seem physically. Example: theological systems. Physical Systems: Systems that are physically visible.
Natural System & Man-Made Systems Natural systems: the system is going through a natural process and not man-made. Example: the earth's rotation system. Man-Made Systems: Systems that are designed by humans and involves the interaction between man and machine. Example: information systems

5. System Classification (2)
Deterministic Systems and Probabilistic System
Deterministic system: The system operates with a certain behavior that could be predicted, the interaction between the parts can be detected with certainty than the output can be predicted
Ex : Computer System using program
Probabilistic system
System that the future conditions can not be predicted because it contains elements of probability.
Example: Gambling

6. System Classification (3)
Closed System and Open System
Closed system: The system is not connected and are not affected by the external environment. This system works automatically without any intervening from the outside (in fact no system is completely closed) there is only a relatively closed system
Open System: The system-related and affected by the external environment. This system accept input and produce output to the outside environment or other subsystems, so it should have good control systems

7. System Characteristic
Component Consists of components that interact with each other and working together become a unity. The components can be composed of several subsystems / subsections, where each subsystem has a specific function and will affect the overall system.
System Boundary
An area which limits between one system to another system / with the outside environment. This system allows the boundary system is viewed as a limit of a system indicates the scope of the system

8. System Characteristic (2)
External Environment System Anything beyond the limits of the system that affects the system operational . External environment can be both beneficial and detrimental. Favorable environment must be kept and maintained, otherwise adverse environment should be retained and controlled to compromised the viability of the system.
Interface
interface as media subsystem, which allows resources to flow from one subsystem to another subsystem. Output (output) of the subsystem will be input to other subsystems through liaison as well as to integrate subsystems become a unity

9. System Characteristic (3)
Input
Energy put into the system, can be maintenance input and signal input . Maintenance Input: the energy that entered to system to make system operate, meanwhile input signal is energy processed to obtain the output. For example, in the computer system, program as maintenance input is used to operate the computer and the data is input signal to be processed into information.
Output
Result of processed energy and classified as useful output and residual disposal. Output can be input for other subsystems.

10. System Characteristic (4)
Processor
A system can have a processing section that will transform inputs into outputs. A production system will process the input of raw materials and other ingredients into the output of finished goods. Accounting system will process the transaction data into financial reports and other reports required by management.
Objectives

11. INFORMATION
The data are processed into a form that is more useful and more meaningful for those who receive
Something real / real half to reduce the degree of uncertainty about the state of things / events. For example: information that states that the value of the rupiah will rise, so will reduce the uncertainty about whether an investment will be made

12. Information Quality Relevance Accurate
Information should provide benefits to the wearer. Relevance of the information for each person different from one another
Accurate
Information should be free from errors and not misleading and should clearly reflect the intent. Inaccuracies may occur because of resources (data) impaired / intent to destroy, to change the original data

13. Information Quality (2)
Component of Accurate :
Completeness
Correctness
Security

14. Information Quality (3)
On Time
The resulting information / needs should not be too late (obsolete). Outdated information does not have a good value, so if used as a basis for decision-making would be fatal / errors in decisions and actions
Economics
Information system costs will increase with time

15. Information Quality (4)
Efficient
How many units of production increased due to additional resources in the production process
Trustworthy
An important indicator of information system is to consider the problem of reliability
Usefullness
Nothing better than a system designed in accordance with criteria

16. Information Types Content Form
Information is usually called by the main content or subject matter of the relevant information. The subject: about activity / particular field of activity, ranging from broad to narrow subject level.
Form
Information Description: In the story form with brief and clear sentences
Recapitulation Information
Image Information
Model Information
Statistic Information
Form Information
Animation Information
Simulation Information

17. Information Types (2) Output Anwer of questions Ex : FAQ Report
Periodic Report
On Request Report
Exception Report
Special Report
Predictive Report
Anwer of questions
Ex : FAQ

18. Information and Management Level
Strategic Information
For Top level and used for long time decision
Tactical Information
For Mid Level
Technical Information
For Low level

19. Information Values
To help provide clarity of uncertainty or to reduce uncertainty so that people can make decisions with certainty and more profitable. The greater help to reduce the uncertainty the higher the value of the information.
