Briquettes are biomass-based alternative energy sources. Biomass used in this study is cow dung. The purpose of this research is to utilize cow dung waste as raw material of briquettes, study the effect of using and without using adhesive to briquette’s characteristics and to determine the best briquette composition according to the national quality standard 01-6235-2000. The treatment of raw…
Waste has become a difficult problem to overcome worldwide where plastic consumes 40% of the waste. basically plastic is used as a wrapping tool. because the price is cheap, airtight and resistant to changes in plastic temperature so favored by the community while recycling technology is still expensive and the plastic is difficult to be deciphered by bacteria so that plastic waste accumulates.…
Used oil is used cooking oil that is generally not used for cooking or frying. The use of used cooking oil is very dangerous because it can cause various diseases, then the utilization of used cooking oil by way of clarified again for the manufacture of transparent soap. Transparent soap is bar soap with transparent or translucent appearance. In this study, the use of wood charcoal on refining …

Corrosion is the deterioration of metal by chemical attack or reaction with its environment. It is a constant and continuous problem, often difficult to eliminate completely. One of the method of inhibiting corrosion process is use corrosion inhibitors. Guava leaf extract contains tannins which can be used as inhibitor. AISI 4140 steel is an alloy of nickel and chromium steel. The purpose of th…
Making biodiesel from Palm Fatty Acid Distillate (PFAD) through processes, Esterification processes which produce methyl esters which can be used as an alternative to petroleum substitutes for diesel fuel. The purpose of this research is to utilize PFAD as raw material of biodiesel making with esterification process then continued with transesterification process, Studied the influence of ester…
A mixture of waste cooking oil with diesel fuel there has not been used people to fuel stove the stove. During this time, many people used the oil land on the stove, but the price is very expensive. This study aims to look for materials alternative fuels substitute oil ground to the stove furnace wheelbase. To get the performance of the fuel best eaten do a variety of treatment ratio a mixture …
Pulp industry generally uses wood as raw material for pulp making. The limited number of wood raw materials causes a raw material crisis. Indonesia is a rich country of agricultural and plantation products, one of which is corn. Corn and corncobs contain 44.08% cellulose content that can be used for pulp making. This research uses raw material of corn husk and corn cob. The fixed variables were…
Ink markers are tools that often used for writing on the whiteboard. It's different from chalk, ink markers have high levels of VOC (Volatile Organic Compound) and very harmful to health due to the xylene content in it. One of the chemical constituents in mangosteen peel is tannin. Tannins that contained in mangosteen peel can be processed back into the basic ingredients of ink marker that safe…
The pulp industry generally uses wood as raw material for pulp making. The limited number of wood raw materials causes a raw material crisis. Indonesia is a rich country of agricultural and plantation products, one of which is pineapple leaves. Pineapple leaves contain 71.5% cellulose content that can be used for pulp making. This research uses semi mechanical soda method. The fixed variable of…
Biodiesel is an alternative fuel that is similar to diesel. Previously many biodiesel developed using raw materials of vegetable oil, but for raw materials using animal fat is still not widely developed. One of animal fat that can be used as raw material for making biodiesel is chicken fat. In this study chicken fat will pass through the hydrolysis stage before transesterification into biodiese…
Wrapped oil has not been maximally utilized. The purpose of this research is to utilize cooking oil as fuel mixed with diesel oil with certain ratio. Before the mixture is used as fuel in the furnace stove first, it is treated with a detergent adsorbent. To get the best fuel performance, then treated variation misbah cooking oil : Diesel oil (1:9, 2:8, 3:7, 4:6 and 5:5) treatment ofvariation of…

Durian (Durio zibethinus Murr) is one of plantation which know for long time ago by societies and in general only us the fruits. Most of societies are consume fruit of durian until produce rubbish like seeds and skins of durian. The purposes of this research were to take advantage the rubbish of durian seeds become essence and then analyse the nutrient and test of organoleptic essence that has …
Corrosion is a metal reduction due to a chemical reaction of a metal with its environment. One way to reduce the rate of corrosion is by the addition of the inhibitor. The mangosteen rind contains tannins that can be used as an inhibitor. This research aims to know the value of the rate of metal corrosion inhibitor skin extracts using mangosteen. Sokletasi is used to extract tannin from the bar…
