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…
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…
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…

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…
Ilmu pengetahuan murni dan ilmu pengetahuan terapan merupakan dua hal yang saling berhubungan satu sama lain. Ilmu teapan tidak akan bias berkembang tanpa adanya ilmu pengtahuan murni, dan sebaliknya ilmu pengetahuan murni membutuhkan ilmu ttterapan untuk menyediahkan fasilitas dan peralatan penelitian yang akurat. Fisika terapan merupakan ilmu pengetahuan yang penting pagi pembaca …
The study focuses on advancing dissimilar metal welding techniques. The intense heat during welding leads to thermal expansion or contraction of the metal upon cooling, resulting in residual stresses in the weld area. Post Weld Heat Treatment (PWHT) is employed to alleviate these residual stresses. The research investigates the impact of PWHT on the mechanical and physical properties of joints …
One of the things that affects the water distribution process is energy loss or head loss. Several conditions have an influence on fluid flow losses, such as friction on the pipe walls, bends, enlargement or reduction in the pipe, and other variables so that the pressure in the pipe decreases. Calculation of fluid flow rates in pipe networks shows the relationship between power loss and flow ra…
The radiator is an important component in the automotive industry that functions as a heat exchanger. The way radiators work involves the use of liquids as a heat exchange medium, especially liquids with high thermophysical characteristics such as nanofluids. This study aims to determine the stability and thermophysical properties of TiO2-MWCNT / Aquades nanofluids and the factors that influenc…
