increase in the effectiveness of learning in the
classroom, such as (1) A reduction in the need to print
paper time-sheets along with the resultant time and
cost this process requires. (2)Negating the need for
collection and collation of time-sheets along with the
time and and costs this incurs, as well as the costs for
any subsequent storage of such sheets (3) Reduce
human errors in filling out of time-sheets as as well
as errors which may occur during collation or, in
communication associated from any absenteeism. (4)
To provide valuable data and information resource
which can be quickly and easily accessed by staff. (5)
To provide a real-time information resource to
parents about the presence, or not, of their children in
school. (6) To minimize fraud and to additionally
train students to be honest in recording their presence
in class. (7) To provide important real-time
information to any relevant authority on the exact
numbers and identities of the students in the school in
the event of any emergency situation.
In this study there are few journals that used as
reference sources, there are in the research of RFID-
based Attendance Systems published in Journal
Technic compyer the results of these studies are (1)
the system can only store student attendance data as
many as 45 more ID tags system error will occur. (2)
if the timer is pressed then after 30 minutes the
student does not can do attendance to limit students
who arrive late cannot do absent (1), The other
Journal which used as reference is Attendance
System for college students used Radio Frequency
Identification(RFID) at Electrical Engineering,
universitas Riau and the outcome of the research are
attendance of the Universitas Riau Electrical
Engineering students which are integrated with RFID,
consists of 8 from which have been made using
Visual Basic Express 2010 and to maintain the
database they Created a database using Mysql
2. METHODOLOGY
a. Unified Modelling Language (UML)
UML is a language that has become a standard in the
industry for visualizing, specifying, designing, and
documenting software systems (Booch, G., et al.
2007). UML offers a standard for designing a system
model. Like other languages, UML also has a
notation. UML notation is a set of special forms to
describe various software diagrams. Each form has a
specific meaning and UML explains how these forms
are defined.
a. Building a model for a software system is very
dependent on the construction or ease of
repairing it. A good model is very important to
produce good communication between team
members and to ensure the perfect system
architecture is built.
b. If you want to build a model from a complex
system, it is impossible for us to understand it
as a whole. With the increasing complexity of
the system, visualization and modeling are very
important. UML is created to respond to those
needs.
c. Looking at the historical factors and the drivers
of UML formation, a conclusion can be drawn
regarding the purpose of the establishment of
UML, namely as follows:
a) Describe the conceptual software model of a
textual programming language so that it can be
understood by people who are non-programmers.
b) Build an appropriate, unambiguous, and
complete model that can assist in the stages of
analysis, design, and implementation.
c) Can model several types of programming
languages, and help re-map the model to another
programming language.
d) Assist in software design documentation.
b. Radio Frequency Identification (RFID)
Identification with radio frequency is technology to
identify a person or object by using radio frequency
transmission, especially 125kHz, 13.56Mhz, or 800-
900Mhz. RFID uses radio wave communication to
identify an object or person uniquely. There are
several meanings of RFID, according to (Maryono.
2005), namely:
a. RFID (Radio Frequency Identification) is an
identification method using a tool called RFID
label or transponder (tag) to store and retrieve
data remotely
b. Label or transponder (tag) is an object that can
be installed or inserted in a product, animal, or
even human being to identify using radio
waves. The RFID label consists of a silicon
microchip and antenna.
c.
RFID System Components
RFID tags can be in the form of stickers, paper, cards,
or plastic of various sizes. In each of these tags, there
is a chip that can store certain amounts of
information. RFID tags function as transponders
(transmitter and responder) that contain data using
frequency. RFID tags consist of three types, namely:
