To develop a sustainable concrete solution, the aggregates and cement in mixture were partially replaced with Cocos nucifera endocarp (coconut shell) aggregate biomass ash (sugarcane bagasse ash) respectively. The fresh hardened properties studied for three types of mixes (i) mix 10-30% replacement (BA), (ii) Bagasse scrap steel fiber 10 - 50% coconut shell aggregate. property is positively inf...

Agricultural residues such as Maize Husk, Groundnut Shell, Coconut Shell and Sugarcane Bagasse were collected, sorted, dried ground to particulate fillers. The various fillers characterized in terms of density, moisture content pH value. Single ordinates 150 µm particle size 30 parts per hundred rubber (pphr) loading respectively adopted for all filler types. They used alongside with convention...

Adsorption of heavy metal on the solid surfaces is an important technique to remove them from the industrial wastewaters. The purpose of the present study is to evaluate the ability of agro-waste material coconut shell to remove Cr (VI) from wastewater. The extant of removal was found to be dependent on pH, contact time, adsorbent dose, concentration of metal and particle size. The adsorption f...

Coconut is one of the industrial plants that plays an important role in Indonesian economy. The part coconut has a high economic value shell. This study aims to see maximum temperature shell pyrolysis reactor and examine spectrum pattern charcoal purified using activation hydrochloric acid (HCl), acetic (CH 3 COOH), nitric (HNO ) hot water (H 2 O). process steps are carried out at ± 310 °C for ...

Industrialization and urbanization have led to the release of increasing amounts of heavy metals into the environment. Metal ion contamination of drinking water and waste water is a serious ongoing problem especially with high toxic metals such as lead and cadmium and less toxic metals such as copper and zinc. Several biological materials have attracted many researchers and scientists as they o...

In occupational hygiene, activated carbon produced from coconut shell is a common adsorbent material for harmful substances including organic vapors due to its outstanding adsorption capacity and cost advantage. However, moisture adsorption of the carbon generally decreases the adsorption capacity for organic vapors. In a previous report, we prepared several coconut shell activated carbons whic...
