KARAKTERISASI CROSSDRAFT GASIFIER MENGGUNAKAN KULIT KOPI SEBAGAI BAHAN BAKAR.

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…

GASIFIKASI SEKAM PADI PADA UPDRAFT GASIFIER DENGAN GAS KELUAR DARI ARAH REDUK…

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…

EFEK POST WELDING HEAT TREATMENT PADA SIFAT MEKANIK DAN FISIK PADA SAMBUNGAN …

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…
