Journal of Renewable Energy and Mechanics Vol. 4 No. 02 (2021): Journal of Renewable Energy and Mechanics (REM)
Publisher : UIR PRESS

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

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.

Repeated welding caused by welding defects in the weld joint will result in changes in the mechanical properties of the weld joint, especially in the Heat Affected Zone (HAZ). Significant changes will occur when welding on steel materials that have undergone special treatment during the manufacturing process, such as quenched and tempered S690Q steel. S690Q steel is a structural steel with high yield strength with quenched and tempered conditions. The research was conducted by doing repeated welding as a simulation of the repair process using the GMAW process. Macro observations as well as tensile, bending, hardness, toughness tests were carried out on cross sections of welded joints. From the results of all the tests carried out the results meet the requirements of the BS EN ISO 15614-1 standard, but the results of the hardness test can identify significant changes in mechanical properties in the HAZ, especially in the bottom or root pass and hot pass areas. The average hardness value decreased from 334.07 HV at the top (face) to 209.55 HV and 198.88 HV at the bottom (hot pass and root pass) on the left side of the HAZ. While on the right side of the HAZ, the hardness value is 337.40 HV to 254.34 HV and 208.64 HV. Keywords: HAZ, S690Q, Structural Steel, Quenched and Tempered Steel

Experimental Investigation of Natural Plant Extracts as A Green Corrosion Inhibitor in Steel Muhamad Akrom
Journal of Renewable Energy and Mechanics Vol. 5 No. 01 (2022): REM VOL 5 NO 01 2022
Publisher : UIR PRESS

Natural plant extracts show excellent performance in inhibiting steel corrosion. Steel has a relatively weak resistance to corrosion when in a corrosive environment. The use of natural plant extracts as green corrosion inhibitors is able to provide good performance with high inhibition efficiency. Experimental methods such as gravimetric analysis, potentiodynamic polarization, and electrochemical impedance spectroscopy are commonly used to investigate corrosion inhibition based on corrosion activity. A comparative literature review of this work is important for the development and utilization of green inhibitors. Experimental studies still do not clearly reveal the mechanism of adsorption and inhibition of molecular inhibitors at the atomic level. For this reason, future developments are very important to study theoretically at the atomic level of the main components of natural plant extracts as corrosion inhibitors, so that it is hoped that there will be a clear and systematic understanding of the mechanism of corrosion inhibition in steel.

With the decreasing of world oil reserves, energy savings programs have started across the entire world. Recently, Indonesia has now become one of the importing countries for crude oil. Biomass gasification sustainability, especially in Indonesia, is very guaranteed because of the abundant availability of biomass in Indonesia. The goals of this study are examine the 5 kW diesel generator performance against various load with diesel fuel and diesel fuel plus syngas (synthetic gas) from sawdust. This research was carried out at Renewable Energy Laboratorium of Engineering Faculty UNTIRTA. The author performed this research using 5,2 kW total load of halogen lamp. In this research the load used was only at 3.2 kW because of the "not optimal condition" of the diesel generator resulting in not optimal engine rotation. Diesel generator power value at low loading point was increased. Whereas, at high loading point was decreased.
