Koperasi Indonesia
BENTUK : Logo Sekuntum Bunga Teratai bertuliskan KOPERASI INDONESIA
Sila pertama ini mengandung makna bahwa bangsa Indonesia adalah
bangsa yang percaya akan adanya Tuhan Yang Maha Esa. Sebagai wujud
penerapannya, maka keanggotaan koperasi Indonesia terbuka untuk semua
penganut agama/kepercayaan dan golongan, serta setiap anggota koperasi
wajib menghormati agama/kepercayaan yang dianut oleh anggota yang lain.
Koperasi juga sangat mementingkan kejujuran. Baik pengurus, manajer,
pengawas, dan anggota koperasi harus berlaku jujur sebagai perwujudan
pengamalan sila pertama Pancasila.
b) Kemanusiaan yang adil dan beradab
Penerapan dari sila kedua Pancasila ini adalah:
(1) koperasi tidak membedakan kedudukan sosial, agama, dan golongan
masing-masing anggota; dan
(2) semua anggota koperasi berhak mendapat perlakuan yang sama dan adil.
c) Persatuan Indonesia
Penerapan sila ketiga dalam koperasi adalah bahwa di dalam koperasi
tidak mengenal perbedaan suku, agama, ras, antargolongan, politik atau status
sosial anggotanya. Semua anggota bersatu dalam wadah koperasi.
Koperasi harus mampu menempatkan rasa solidaritas tanpa memandang
asal usul dan status sosial.
d) Kerakyatan yang dipimpin oleh hikmat kebijaksanaan dalam
permusyawaratan/perwakilan
Dalam koperasi, pengambilan keputusan harus didasarkan pada
musyawarah mufakat. Jika terdapat perbedaan pendapat di antara anggota
koperasi, maka hal tersebut harus dipecahkan melalui musyawarah mufakat
dalam rapat anggota. Pelaksanaan musyawarah mufakat dalam koperasi
mencerminkan penerapan sila keempat Pancasila.
106 Ekonomi XII untuk SMA/MA
e) Keadilan sosial bagi seluruh rakyat Indonesia
Penerapan sila kelima Pancasila dalam koperasi tercermin dalam hal
berikut ini.
(1) Tujuan koperasi adalah untuk memajukan kesejahteraan anggota dan
turut membangun perekonomian nasional menuju masyarakat adil dan
makmur.
(2) Sisa hasil usaha dibagikan kepada anggota sebanding dengan jasa dan
karyanya.
(3) Koperasi mengutamakan perbuatan-perbuatan yang luhur dan penuh
kekeluargaan serta kegotongroyongan yang merupakan ciri khas koperasi
Indonesia sebagai badan usaha.

Electronic Circuit Symbols
Wires
Electronic Component | Circuit Symbol | Description |
Wire |
Used to connect one component to another.
|
|
Wires Joined |
One device may be connected to another
through wires. This is represented by drawing “blobs” on the point where
they are shorted.
|
|
Unjoined Wires |
When circuits are drawn some wires may
not touch others. This can only be shown by bridging them or by drawing
them without blobs. But bridging is commonly practised as there will not
arise any confusion.
|
Power Supplies
Electronic Component | Circuit Symbol | Description |
Cell |
Used to provide a supply for a circuit.
|
|
Battery |
A battery has more than a cell and is
used for the same purpose. The smaller terminal is negative and the
larger one is positive. Abbreviated as ‘B’.
|
|
DC Supply |
Used as a DC power supply, that is, the current will always flow in one direction.
|
|
AC Supply |
Used as AC power supply, that is, the current will keep alternating directions.
|
|
Fuse |
Used
in circuits where a probability of excessive current flows. The fuse
will break the circuit if excessive current flows and saves the other
devices from damage.
|
|
Transformer |
Used as an ac power supply. Consists of
two coils, the primary and secondary that are linked together through an
iron core. There is no physical connection between the two coils. The
principle of mutual inductance is used to obtain power. Abbreviated as
‘T’.
|
|
Earth/Ground |
Used in electronic circuits to represent
the 0 volts of the power supply. It can also be defined as the real
earth , when it is applied in radio circuits and power circuits.
|
Resistor
Electronic Component | Circuit Symbol | Description |
Resistor |
A resistor is used to restrict the amount of current flow through a device. Abbreviated as ‘R’.
|
|
Rheostat |
A rheostat is used to control the current flow with two contacts. Applicable in controlling lamp brightness, capacitor charge rate, etc.
|
|
Potentiometer |
