KATA PENGANTAR

Puji syukur penulis ucapkan kepada Tuhan Yang Maha Kuasa yang selalu

memberi rahmat serta karuniaNya, sehingga penulis mampu menyelesaikan

perancangan serta penulisan tugas akhir berjudul “Perancangan Sistem Pengukur

Panjang Produksi Galvalum Menggunakan Sensor Rotary Encoder di PT. Kepuh

Kencana Arum” ini, sebagai syarat kelulusan di Fakultas Teknik Elektronika dan

Komputer Universitas Kristen Satya Wacana.

Penulis juga mengucapkan terima kasih kepada berbagai pihak yang telah secara

langsung maupun tidak langsung membantu dalam penyelesaian pembuatan dan

penulisan tugas akhir ini. Penulis mengucapkan terima kasih khusus kepada :

1. Tuhan Yang Maha Kuasa yang selalu memberi rahmat serta karuniaNya dalam

setiap kegiatan yang penulis telah tempuh selama pendidikan S1 di FTEK

UKSW dari awal hingga akhir.

2. Bapak Rudy Kurniawan dan Ibu Eny Hiendarti selaku orang tua penulis yang

selalu memberikan doa, motivasi, dukungan, dan didikan.

3. Bapak Deddy Susilo, S.T., M.Eng. serta Bapak Atyanta Nika R, M.BA,M.T.

selaku dosen pembimbing yang telah memberikan banyak arahan dan

ABSTRACT

Productivity monitoring is important in a business because the data obtained

becomes a reference. Lack of monitoring in production can lead to several losses such

as errors in recording by officers or manipulation of data carried out by workers that can

harm the company. PT. Kepuh Kencana Arum monitors every process that the forming

machine does manually, starting from the opening of the base material (galvalume) to

producing a product form (Wave Roof, Hollow). Therefore, the system design is done

in this thesis to meet the monitoring needs of PT. Kepuh Kencana Arum to be able to

monitor the productivity of each machine in each city in real-time. To fulfill one of the

back-end parts in the Telemetry system, the final project was made using Arduino UNO

as a microcontroller. Arduino UNO here works as a tool to facilitate monitoring of

forming machine performance (yield / number of products) by utilizing readers of

sensors that have been installed in the forming machine accurately and precisely. From

the results of the tests that have been carried out, the use of Arduino UNO can monitor

the performance of the forming machine by reading the rotary encoder, push button,

limit switch installed on the forming machine using an optocoupler circuit. By using a

rotary encoder optocoupler circuit, push button, the limit switch on Arduino UNO has

errata below 2%.

Keywords : Rotary encoder, optocoupler, push button, limit switch dan Arduino
