Co-op Students di PT PLN (Persero)

Sekarang ini  banyak sekali model CRS yang di lakukan oleh perusahaan salah satunya yaitu Co-op Student. CSR adalah Tanggung jawab Sosial Perusahaan atau Corporate Social Responsibility (selanjutnya dalam artikel akan disingkat CSR) adalah suatu konsep bahwa organisasi, khususnya (namun bukan hanya) perusahaan adalah memiliki suatu tanggung jawab terhadap konsumen, karyawan, pemegang saham, komunitas dan lingkungan dalam segala aspek operasional perusahaan.

Memperbaiki level transmitter  baca manual book yah :)

Memperbaiki alat instrumentasi

Meeting Pagi lagi diskusi :)

Co-op students banyak di lakukan oleh perusahaan- perusahaan besar yaitu  Telkom ,PLN yaitu sebagai CSR. Saya berkesempatan untuk Co-op Students Di PLTU Tarahan, Lampung. Selama co-op ini banyak ilmu yang saya dapatkan terutama dalam bidang saya yaitu Electrical Engineering. Disini daya analisa kemampuan teknik saya dapatkan dimana ilmu-ilmu tersebut tentu tidak di dapatkan selama kuliah yang lebih condong ke teoritis sedangkan di PLTU ini saya mendapatkan teoritis sekaligus aplikatif tentang peroses pembangkitan listrik.
Selain ilmu teoritis tentu juga ilmu social yaitu bagaimana cara berinteraksi sesame karyawan dan berkomunikasi dengan secara teknis dan diskusi-diskusi mengenai permasalahan yang ada. Saya merasa beruntung sekali mendapatkan kesempatan co-op ini karena tidak semua mahasiswa memperolehnya karena ada tesnya

pH transmitter calibration

In chemistry, pH is a measure of the activity of the (solvated) hydrogen ion. p[H], which measures the hydrogen ion concentration is closely related to, and is often written as, pH.^[1] Pure water has a pH very close to 7 at 25°C. Solutions with a pH less than 7 are said to be acidic and solutions with a pH greater than 7 are basic or alkaline. The pH scale is traceable to a set of standard solutions whose pH is established by international agreement.^[2] Primary pH standard values are determined using a concentration cell with transference, by measuring the potential difference between a hydrogen electrode and a standard electrode such as the silver chloride electrode. Measurement of pH for aqueous solutions can be done with a glass electrode and a pH meter, or using indicators.

In industri have instrumentasison for calibration pH ..

DIGITAL COMPASS DESCRIPTION

Basic Description
The digital compass gives measurements based on Earth's magnetic field for robot navigation. Inside this commonly available MEMS are tiny nano-structures that bend due to electromagnetic fields. When this MEMS experiences any form of EM field, the tiny structures bend by an amount which can be electrically detected. Cheaper digital compasses usually have a resolution of around +/- 5 degrees, but newer and better ones can detect with a better accuracy.

Tips and Uses
• Keep digital compasses far away from anything that emits EM, such as motors, transformers, inductors, etc.
• Large conductive items significantly altar magnetic fields (cars, fridges, steel plates, etc.)
• Use this device to help for navigation, such as robot race tracks or navigating a maze
• because the Earth's magnetic lines of flux "dip" in declination, the compass must remain level for the readings to be accurate. Some electronic compasses employ a 2-axis gimbal in an attempt to keep the compass level, but these are problematic in the rough off-road environments
