Banana peel is one of the wastes that can pollute environment so it needs to be utilized. One ingredients in kepok banana peels starch (carbohydrates). converted into glucose by hydrolysis method. This study aimed find out effect suspension levels on reaction kinetics process. The process used 2 N oxalic acid with times 10, 20, 30, 40 and 50 minutes (gr/mlcamp) were 10/250, 20/250 30/250. resul...

Oil waste produced from motor vehicle lubricants can pollute the environment. One alternative that be done to prevent environmental pollution is by utilizing oil as fuel. Several factors affect temperature and quality of combustion, namely air flow rate addition water vapor in combustion process. The purpose this study was determine effect number steam holes on efficiency stove with used resear...

Abstract A modification method of clay mineral surface was developed to improve its adsorption capacity uranium. Uranium is a radionuclide with high toxicity and extremely long half-life, which can pollute the environment endanger human health. This study proposes new activation phosphoric acid for rapid uranium from aqueous solution. Compared other methods, this has advantages availability raw...

One of the basic assignments modern society is preserving quality freshwater resources, especially drinking water. Line facilities potentially pose a higher risk to environment due large length extension and diversity they may affect. Storm water drained from railway could pollute surrounding land besides track. Based on data available research, it has been determined that heavy metals (iron, c...

Preventing the spread of Coronavirus Disease 2019 (COVID-19) has become focus epidemiologists as highly infectious respiratory disease spreads primarily by close, person-to-person contact via droplets or skin. Aerosol dissemination may occur in a closed, high-aerosol environment. The aerosols generated dental procedures can pollute surrounding air and device surfaces. In this paper, we summariz...

Abstract In the past few years, efficiency of perovskite cells has been improved rapidly, and current can reach 25.8%. Since lead in materials will pollute environment, so people turn their attention to lead-free tin-based perovskites. Tin-based perovskites are becoming a research hotspot recently due nontoxic properties. However, fast crystallization rate perovskite, improvement is limited. th...
