implementation of KK-PPL integrated in schools SMA N 1 Jember
Lecture Field Work Experience
Program (KK-PPL), an integrated program carried out in S1 FKIP Jember
University is one of the culminating point or estuary program that provides
opportunities for students to establish mastery of pedagogical competence,
personality, professionally and socially in an integrated manner in accordance
with the demands of the Law No. 14/ 2005. Besides, KK-integrated PPL Education
is also intended to improve or enhance the quality of learning in the classroom
and to improve the quality of educational performance of non-teaching that can
optimize the learning achievement conducted by the teacher.
Management of learning in the
classroom is one of the job-oriented professional teachers on the needs of
learners. Therefore to run the KK-PPL is required mastery of a number of
competencies that support, namely pedagogical competence, professional
competence, personal competence and social competence. The
four competencies is an integral competence
from each other. Pedagogical
competence, personality (personal) and social
competence should be able to animate the professional
competence of teachers. So that will occur in
steps of unity movement of teachers in carrying out his duties as a professional
teacher. Strengthening the four competencies in
an integrated way, then in every
action of teachers in learning manage decision
is an act of devotion that can be accounted for in scientific, professional,
and moral.
Competencies possessed by students
in KK-PPL acquired through education and training in a systematic and reliable
by the competent institutions. The process of acquiring competence through a
lot of meaningful educational interaction, namely interaction between students,
student and teacher officials, students and lecturers, students and student,
student and teaching materials. Competence is then enriched also by giving
students practical experience in management or school management,
organizational development students, and the increase in competitive graduate
school, so the achievement of the four competencies of teachers are expected to
be more optimal and relevant to the duties of a professional, either as
teachers or as managers of learning in school. Therefore, the implementation of
the KK-PPL Education for S1 students must provide opportunities for these
interactions occur which will cultivate the necessary competencies possessed by
a professional teacher.
With the implementation of KK-PPL
integrated in schools, it is expected that all the experience gained during the
KK-KK PPL field of learning and non-PPL field of learning will be relevant to
the needs as a professional teacher, because the KK-integrated PPL Education
implemented in a real environment that will became the task of future university
students if they had graduated and served as a
teacher.
and for the relation, i give my lesson plan during implementation KK-PPL.
happy fun with your international klas....neutronian

Electromagnetic
Induction
Induced
electromotive force
If a coil or
wire is moved in magnetic field, at the end of wire or coir will appear potential
difference called induced electromotive force (induced EMF). The potential
difference produced electric current in the wire or coil called induced
current.
Inducced current is produced by difference potential
called induced electromotive force (EMF). Induced EMF is can appear because of
the presence of relative motion between the coil and bar magnet, induced EMF is
one example of electromagnetic induction.
To increase induced EMF it can be done by the method
of:
a. Accelerating the motion of taking in and out a bar
magnet.
b. Adding the number of winding in the coil.
c. Using a stronger magnet.
Generator
Generator is machine that change kinetic/mechanical
energy into electric energy.
Principally, a generator consists of rectangle-shaped
coil that is located in a strong enough magnetic field.this magnetic field
stems from two magnetic field that flank a coil, so the magnetic force lines
that go out from the north pole (N) willl penetrate the coil before reaching
the south pole (S). when the coil is rotate, the number of magnetic force lines
will change according to the position of the coil in relation to magnet. The
change of magnetic force lines produced induced EMF at the end of the coil and
finally produced elctric energy.
There are two kind of generator. Those are alternating
current and direct current generator. The difference of those two kind is
located in its conductor ring.
Transformator
In figure. A is connected to the sourece of AC and B
is connected to galvanometer. Coil A is called primer coil, and B is called
secondary coil.when electric current flow fromAC corrent source in primary
coil. Around the coil magnetic force lines appear. Some of the magnetic force
lines from the primary coil enter the secondary coil. Because the elctric
current thet is produced by the AC current source is allternating current, the
number of its magnetic force lines will change againts times. This cause the
number of its magnetic force lines that are covered by the secondary coil will
also change. As a result induced electric current will flow in the secondary
coil and the galvanometer’s needle will deflected.
Working principle of transformator
If you observe a transformator, you will see the
number of winding in both coil differenct. One winding is more then the other.
The difference of the number of winding in primary or
secondary coils will determines the function of the transformator, whether to
step up (increase) or step down (decrease) voltages.
The ratio between the number of winding in primary and
secondary coils to the voltages in primary and secondary coils in a tranformer
is formulated by:
Ry coils
Where:
Vs= voltage in primary coils
Vp= voltage in secondary coils
Ns= winding in secondry coils
Np= winding in primary coils
In an ideal transformator, power that runs from a
primary coil to the secondary coil is equal to 100% (n=100%).
Pp=Ps
Vp Ip= Vs Is
= 
Ip= electric current in primery coil
Is= electric current in secondary coil
The efficiency of transformator
=the efficiency of transformator (100%)
