5. Conversation Describing Abilities

Oneday  Laila come to the laboratory ,firstly she found Retno in the laboratory. And then They are talking about anything.

Laila    : hey retno ,why you are come early today ? it is not unusualy .

Retno  : hahaha ... I just want to doing positive in today lai.

Laila    : okay , I think this is good. By the way what the job today ret ?

Retno  : the job today is practicume tranducer LDR. Do you have the job papers lai ?

Laila    : I have ret. Okay I will take it for you.

Retno  : thank’s lai. By the way where we can find LDR lai ?

Laila    : LDR ? what is that retno ?

Retno  : LDR is Light Dependent Resistor , this is a component that has a (variable) resistance that changes with the light intensity that falls upon it. This allows them to be used in light sensing circuits.

Laila    : and then , do you know another ?

Retno  : When light falls upon it then the resistance changes. Values of the resistance of the LDR may change over many orders of magnitude the value of the resistance falling as the level of light increases.

Laila    : what is the characteristic features of  LDR ret?

Retno  : we can look the material of  LDR is cadmium sulfide .

Laila    : oh I see ret, I seem to see LDR there is in the cupboard.

Retno  : can you take it for me ?

Laila    : okay ret, I will take it for you .

Retno  : don’t forget to take the project board too lai .

Laila    : okay , and then ?anyone else ?

Retno  : yes , we need resistance 470 ohm , 1000 ohm and 220 ohm .

Laila    : ret , do you know the color of them ?

Retno  : 470 ohm is yellow, purple and brown . get it lai ?

Laila    : yes I get it ret, and then 1000 ohm ?

Retno  : 1000 ohm is brown, black , and red lai . there’s ?

Laila    : just a moment ret , I will look for it .

Retno  : okay , I will wait you in here .

Laila    : ret , I get it 1000 ohm . and the last what is the color ?

Retno  : 220 ohm is red,red and brown lai.

Laila    : okay  retno , I get it all . now I will practice with you .

They are practicing together on laboratory. The bell is ringing, they are prepare to the class for next lesson. On the class laila ask retno about mathematics problems .

Laila    : ret do you have finishing your mathematic problem ?

Retno  : yes I have . why you ask about it lai ? there’s problem ?

Laila    : yes there’s. I was finishing my mathematic firstly and i was correction

, but not same with answer key. I feel confused ret .

Retno      : what should I do for you lai ?

Laila       : can you help me to correction my answer sheet?

Retno      : okay , give me your paper please !

Retno have correction laila’s paper in the class. After 20 minutes later .

 Retno     : lai , come here please ! now I know what the problem you have .

Laila       : what is that ret ?

Retno      : in second step u must change in polar form , because For the operation of multiplication of complex numbers is easier if using Polar form.

Laila       : oh I see ret , and then for the In addition operations using complex numbers Rectangular shape, right ?

Retno      : yes , all right lai. Now you can answer the question again. Fighting laila .

Laila       : thank you retno .

After laila answer the question of mathematic, they are back to laboratory to practicume . suddenly Retno come to the laila to ask about  operate the electronic devices. 

Retno      : lai , can you teach me about how to delete this program on CPM1A ?

Laila       : okay , I will teach you ret. The first you must turn on at the PLC , look the key , on program , monitor or run ?

Retno      : and then what the is the right for the key if we will to delete this program ?

Laila       : if you know the program is false ,you can choose program to justifying wrong. And then you can input the password and you can delete this program .

Retno      : password ? what is the password lai ?

Laila       : the password is CLR_MONTR_CLR.

Retno      : okay laila . now I can delete my program , right?

Laila       : yes ret , you can turn CLR_SET_NOT_RESET_MONTR_CLR to delete your program . 

Retno      : that’s great , thanks you so much laila , you are the best.

Laila       : please ret , don’t make me arrogant . 

Retno      : lai , my program less one command , what should I do ?

Laila       : you can turn CLR , drop down and then you can write the program , next you turn INS and drop down again . 

Retno      : okay , if we want to running the program we can change the key to the  RUN , right ?

Laila       : yes , you are right . 

Retno      : okay thank you lai . 

Laila       : okay retno, you are welcome.

After 20 minutes later , retno ask to laila about how to wiring the PLC .

Retno      : lai, can I look your CPM1A ?

Laila       : of course ret . by the way do you know if we need power supply to practicume today?

Retno      : I know lai , but I can’t to operate the devices. 

Laila       : what should I do for you ? maybe I can help you

Retno      : I feel so confused lai , how to calibration the power supply if we need current ?

Laila       : let’s me doing for you . I will teach you how to operate the power supply if we need current we can connect the two pole cable, and then we can manage how the current.

Retno      : but  if we need voltages what we should to do ?

Laila       : we can use multimeters to know if we need voltages. Finishing ret.

They are practicing together on laboratory until the bell is ringing to back to the home.
