Onmi-directional robot has the advantage of movement when compared to other cars robots, where motion can be generated with the flexibility of linear and rotational rnotion that can be done simultaneously or independently. This is due to the omnidirectional robot using special wheels called omni-directional wheels. Omnidirectional wheel is a unique because it has the ability to move freely in b…
Nanofluid is a suspension containing nanoparticles or a fluid with nanoparticles dispersed in it. The addition of surfactants to nanofluids aims to increase the dispersion properties of particles by reducing the surface tension of the liquid. The nanofluid preparation process is an important role in this research to obtain accurate results. Nanofluid preparation in this study used a two-step me…
Tectonically, the research area is located in the South Sumatra Basin. The South Sumatra Basin is known as a complex geological area. In general, the research area is located in the Early Postrift (Early Miocene-Middle Miocene). In the Talang Baru area, research on the diagenesis of the Gumai Formation calcareous sandstone has not been carried out comprehensively, so this study aims to determin…
Nanofluid is a solution consisting of nanoparticles dispersed in a base fluid, typically derived from metals, metal oxides, and various forms of carbon. The addition of nanoparticles to the fluid enhances its thermal, mechanical, and electrical properties. To ensure the stability and uniform distribution of nanoparticles within the fluid, surfactants are used as agents to stabilize and disperse…
Sumur “X” merupakan sumur migas pada lapangan pengembangan di daerah Rimau dengan metode area pengangkatan fluida menggunakan sucker rod pump. Laju produksi teraktual yaitu 120 BFPD. Berdasarkan analisa kurva IPR (Inflow Performance Relationship), laju produksi maksimalnya mencapai 433 BFPD (Barrel Fluid per Day). Nilai efisiensi volumetris pompa (Ev) sebesar 48% tergolong rendah. Untuk men…
Secara umum metode produksi minyak bumi dibagi dua, yaitu metode sembur alam {natural flow) dan pengangkatan buatan {artificial lift). Sembur alam merupakan metode mengalirnya fluida dari zona perforasi ke permukaan sumur secara alamiah, hal ini disebabkan oleh tekanan reservoir yang mendorong fluida naik ke permukaan masih sangat tinggi. Seiring diproduksinya sumur tersebut,maka tekanan reserv…
Coffee skins contain many complex organic components, air content in biomass or moisture (M) and little ash. Organic components consist of four basic elements, namely carbon (C), hydrogen (H), oxygen (O) and nitrogen (N). Biomass can also contain small amounts of chlorine (Cl) and sulfur (S). Thermal design for biomass utilization systems, whether gasifier or combustion, requires the compositio…
Rice husks are a biomass that is quite abundant in Indonesia, especially in South Sumatra. One method that can be used to convert rice husks into energy is the gasification process. The gasification process occurs in a gasifier reactor where in this research it was carried out in an updraft type gasifier. Updraft gasifier is a type of gasifier that is very popular because of its simple construc…
Seiring perkembangan zaman pengunaan bahan bakar fosil semakin lama akan semakin meningkat yang mencangkup dalam aspek-aspek sosial, ekonomi, dan lingkungan. Selain itu, bahan bakar fosil juga berperan penting dalam peningkatan berbagai bidang, terutama di bidang industri. Akibat pesatnya pengunaan bahan bakar fosil yang akan berakibat polusi udara semakin mengkhawatirkan maka dari itu diperluk…
A fermentor is a device used in the fermentation process for bioethanol production. The development of computational technology has contributed significantly to understanding and optimizing fermentor performance. One of the approaches used is Computational Fluid Dynamics (CFD) analysis, which enables numerical simulations of fluid flow and mass transfer within the fermentor. CFD simulations on …
Silicone Rubber insulation is used because it has a good dielectric properties. The use of Silicone Rubber for a long time can cause the insulation to expand (increase in length) and result in a decrease in the quality of the insulation. Aluminum has low density, corrosion resistance and good elasticity. In addition, aluminum has tailorability properties, so that the required mechanical propert…
This study reported the leakage current and resistance value in Silicone Rubber (SiR) insulation material mix Silicone dioxide (SiO2) filler by applying voltage of 220 V, 500 V, and 1000 V. Test samples were sheet form with dimensions of 50 × 25 mm and thickness 1 mm. Test are carried out using an Aluminum tape electrode system glued on both sides of the object with a gap distance of 20 mm. Th…
Nanofluida merupakan dua campuran fase dimana fase yang biasanya cairan dan fase yang terdispersi terdiri dari nanopartikel padat yang sangat halus, berukuran lebih kecil daripada 100 nm. Penelitian dalam bidang nanofluida banyak dilakukan khususnya dalam aplikasinya sebagai pendingin dalam sistem penukar panas (heat exchanger). Nanofluida memiliki sifat–sifat yang berbeda dengan fluida dasar…
