Abstract

ABSTRAKDalam pencarian suatu obyek di bawah air dibutuhkan metode khusus yang digunakan dengan suara (gelombang akustik), dikarenakan suara dapat merambat dalam jarak jauh pada air. Frekuensi yang dapat diterima oleh SONAR bergantung pada alat penerima yang mengubah suara menjadi sinyal elektrik agar dapat mendeteksi frekuensi, alat penerima ini dinamakan hydrophone. Dalam penelitian ini dibuat perancangan prototipe hydrophone, yang tersusun dari transducer (akustik-elektrik) dan penguat. Berdasarkan perancangan yang telah dibuat prototipe hydrophone mampu menerima (menangkap) gelombang akustik pada range frekuensi 100 Hz – 60 kHz, dengan menggunakan transducer berupa condenser microphone yang diselimuti oleh bahan karet tipis. Prototipe hydrophone tanpa pelindung anti air, dengan pelindung anti air, dan di dalam air dapat menerima (menangkap) gelombang akustik.Kata Kunci: SONAR, hydrophone, transducer ABSTRACTIn finding an object beneath the water there has to be a specific method used sound (accoustic wave) in keeping with it can apread in long distance in the depth of water. The frequency which can be detected by sonar system, counts on the receiver which converts sound to electric signal so that the frequency can be detected and it is called hydrophone. In this research, there is hydrophone prototype which piled up by tranducer and amplifier. Based on the trial, hydrophone prototype can detect accoustic wave in range 100 Hz-60 kHz with the condensor microphone as a transducer covered of thin rubber material. Besides, hydrophone prototype with or without water resistor is still capable to detect acoustic wave.   Keywords: SONAR, hydrophone, transducer

Abstract

ABSTRAKElectrical Submersible Pump (ESP) merupakan salah satu sistem pumping yang digunakan dalam produksi minyak bumi dengan menggunakan motor induksi sebagai penggerak utama yang ditanamkan ke dalam sumur. Seperti yang telah diketahui bahwa kinerja sistem ESP yang digunakan di PT Baker Hughes Indonesia, berlangsung secara terus-menerus. Hal ini dapat mempengaruhi kinerja motor yang menyebabkan hasil produksi menurun. Hasil produksi minyak mentah berbeda-beda untuk masing-masing wellpad, dimana 1 wellpad terdiri dari beberapa sumur dan masing-masing sumur memiliki kedalaman yang berbeda sehingga kapasitas motor dan pompa yang digunakan berbeda pula. Kapasitas pompa sangat bergantung pada parameter sumur minyak yaitu kedalaman sumur, Total Dynamic Head (TDH), hasil produksi perjam, dan hasil produksi perhari per-TDH. Oleh karena itu, dapat ditentukan korelasi antara kapasitas Motor ESP terhadap keempat paramter sumur tersebut. Berdasarkan hasil pengolahan data dan analisis sistem diperoleh bahwa kapasitas daya motor berbanding lurus secara linier terhadap keempat parameter tersebut. Kata Kunci: ESP, wellpad, hasil produksi, kapasitas daya motor.ABSTRACTElectrical Submersible Pump (ESP) is one of the pumping system used in the production of petroleum by using an induction motor as the prime mover which are implanted into the well. As we known that the performance of the ESP system which is used in PT Baker Hughes Indonesia, has worked continuously. This can affect motor performance which led to decreased production yield. The production of crude oil varies for each well pad, that 1 well pad consists of several wells and each well has a different depth so that the capacity of the motor and pump are used differently. Pump capacity is very dependent on the parameters of the oil wells, the depth of the well, Total Dynamic Head (TDH), the hourly production and production per day per-TDH. Therefore, we can determine the correlation between the motor power againts the four well’s parameters. Based on the results of data processing and systems analysis showed that the motor power linearly proportional to the four parameters.Keywords: ESP, well pad, production, capacity motor power.
