Salah satu bahan baling-baling yang banyak digunakan adalah aluminium paduan. Kerusakan propeller yang terjadi di dominasi oleh terjadinya patah pada salah satu atau beberapa daunnya. Kerusakan berupa patahnya propeller tidak hanya disebabkan oleh beban kerja propeller, melainkan sebagai hasil akumulasi antara kerja propeller dan lingkungan kerjanya yang korosif. Salah satu cara meningkatkan sifat mekanis paduan aluminium adalah dengan perlakuan panas penuaan (aging treatment). Penelitian ini bertujuan untuk mendapatkan laju korosi akibat pengaruh kecepatan putaran propeller dan aging. Pada penelitian ini material Al paduan di-aging pada temperatur 170°C selama 180 menit. Material tanpa aging dan hasil aging kemudian diuji korosi dengan metode celup pada variasi putaran propeller 800 rpm, 1000 rpm, 1200, dan 1500 rpm dengan waktu perendaman 12 jam , 24 jam, 48 jam,dan 168 jam. Hasil penelitian menunjukan bahwa kecepatan putaran propeller mempengaruhi laju korosi material. Spesimen yang diputar pada kecepatan 1500 rpm memiliki laju korosi 1,0084 mm/year untuk material tanpa aging dan 0,9447 mm/year untuk material dengan aging. Laju korosi ini lebih besar dibandingkan spesimen yang diputar pada kecepatan 800 rpm, 1000 rpm dan 1200 rpm. Laju korosi pada putaran 800 rpm adalah 0,6472 mm/year untuk material tanpa aging dan 0,5141 mm/year Utuk material dengan aging. Aging yang dilakukan pada material dapat menurunkan laju korosi dari 0,6472 mm/year menjadi 0,5141 mm/year pada putaran 800 rpm, 0,7913 mm/year Menjadi 0,6775 mm/year pada putaran 1000 rpm, 0,8805 mm/year menjadi 7438 mm/year Pada putaran 1200 rpm dan 1,0084 mm/year menjadi 0,9447 mm year pada putaran 1500 rpm. Pengamatan foto mikro menunjukan bahwa jenis korosi yang terjadi adalah korosi kavitasi.

The condition of a well if it is produced continuously will cause reservoir pressure to fall, and the flow rate will also go down, as a result the productivity of the well will also decrease. For this reason, there is a need for energy that can help lift fluid up to the surface. In the primary method there are 2 stages of production, namely natural flow where oil is raised directly through the tubing surface, and artificial lift is the method of obtaining oil by using the aid of additional tools. In the oil industry there are various types of artificial lifts, one of which is an electric submersible pump (ESP). Electric Submersible Pump is an electric pump that is immersed into a liquid. This pump is made on the basis of a multilevel centrifugal pump where each level has an impeller and iffuser which aims to push the fluid to the surface. ESP planning is strongly influenced by the roductivity of production wells. The rate of fluid production influences the selection of pump type and size. This is because each pump has its own production rate based on the type and size of each pump used. In the course of producing oil, there will certainly be a problem that will cause a decline in production, therefore it is necessary to evaluate and redesign the ESP pump, in an effort to optimize the production potential of these wells. In this study an evaluation of the performance of the electrical submersible pump will be carried out and a pump redesigned to optimize production using AutographPC software on the well X in the field Y Kondisi suatu sumur jika diproduksikan terus-menerus akan mengakibatkan tekananreservoir turun, dan laju alir akan turun pula, akibatnya produktivitas sumur akan turunjuga. Untuk itu perlu adanya tenaga yang dapat membantu mengangkat fluida sampaikepermukaan. Dalam metode primer terdapat 2 tahapan produksi yaitu natural flowdimana minyak terangkat kepermukaan langsung melalu tubing, dan artificial liftmerupakan metode perolehan minyak dengan menggunakan bantuan alat tambahan.Dalam dunia perminyakan ada berbagai macam jenis pengangkatan buatan salahsatunya adalah electric submersible pump (ESP). Electric Submersibel Pump merupakan pompa listrik yang dibenamkan kedalam cairan.Pompa ini dibuat atas dasar pompa sentrifugal bertingkat banyak dimana setiap tingkatmempunyai impeller dan diffuser yang bertujuan untuk mendorong fluida kepermukaan.Perencanaan ESP sangat dipengaruhi oleh produktivitas sumur produksi. Laju produksifluida berpengaruh terhadap pemilihan jenis dan ukuran pompa. Hal ini dikarenakantiap-tiap pompa memiliki laju produksi sendiri berdasarkan jenis dan ukuran tiap- tiappompa yang dipakai. Dalam kegiatan memproduksikan minyak tentu suatu saat akan terjadi permasalahanyang mengakibatkan menurunnya produksi, Oleh karena itu perlu dilaksanakan evaluasidan design ulang pompa ESP, sebagai upaya untuk mengoptimalkan potensi produksisumur-sumur tersebut. Pada penelitian ini akan dilakukan evaluasi kinerja electricalsubmersible pump dan melakukan desain ulang pompa untuk optimasi produksidengan menggunakan software AutographPC pada sumur X lapangan y Kata kunci: electric submersible pump, AutographPC, laju produksi

Lead Apron is a Personal Protective Equipment (PPE) against the effect of Ionizing Radiation such as X-ray. It is essential for the radiation worker to wear Radiation Protection Equipment during commissions involving ionizing radiation. In Pekanbaru, Indonesia the most common radiation worker is Radiographer which help in hospital for diagnose. In this study the Lead Apron analyzed were 6 apron which suspected to have fault due to its inappropriate tend using NDT radiography methods. Radiography methods have advantage of graphic presentation of object unlike any NDT-methods. The image produce from radiography were analyzed using Computed Radiography (CR) and measured the defection of the material. There was only 3 of 6 Lead Apron appropriate for radiation protection.

During this time the ship's hull often occurs due to corrosion levels of salt in the Indonesian sea varies. The repair process often done to overcome this problem is by sandblasting which aims to clean the metal from the surface of the rust and provide suitable surface roughness on the metal surface so that the coating material can stick properly. This study aims to determine the size of silica sand and the repetition of the sandblasting process on the value of surface roughness and cleanliness of the material. In this study the SS400 material was sandblasting using 12 mesh, 16 mesh and 20 mesh sand at 7 bar, spraying 1x and 2x. From the test results obtained at a particle size of 20 mesh, 7 bar pressure, repeated spraying 2x which results in a surface roughness of 19.80 µm and cleanliness results achieved according to standard SA 2 1/2 (SSPC-SP10) from these conditions obtained surface roughness values according with the standard surface roughness of sandblasting and the level of cleanliness achieved in accordance with ISO 8503 standards and has been allowed for application.

In producing oil, one of the common problems faced by oil and gas companies is the production of a lot of water. Increased water production causes the storage tank to be unable to accommodate the produced water. To overcome the excess water production, some of the water is injected back into the well. In Field A, an innovation has been made for a water injection pump with the driving force coming from the Electrical Submersible Pump (ESP) pump. The working principle of this ESP pump is to drain water from the disposal well to the injection well. Therefore, in order for the injection to run optimally, synchronization is carried out starting from the water entering the holding tank, the flow rate in the Disposal well and the pump capacity (ESP) for injecting from the holding well to the injection well. The amount of water flow rate injected through the ESP pump is 9,500 BWPD. For this reason, the capacity of the ESP pump as an injection pump is calculated. First, determine the water level in the tank to control the amount of flow that enters the reservoir well. Based on the results of the research that has been done, the water level in the holding tank to get a flow rate of 9,500 BWPD is 4.11 ft. And the results of the calculation of water will be injected using an ESP pump with a number of stages 22 with the TRW Reda Pump Devision pump type. The water will be channeled to the injection well with a type of galvanized iron pipe with a diameter of the main pipe (mainline) of 6 inches. From the disposal well, it flows with a 4 inch pipe as far as 45.93 ft and a 2 inch pipe as far as 2214.57 ft for well 07. As for wells 60, the flowline size is 4 inches as far as 708.66 ft and 2 inches as far as 987.53 ft.
