Abstract

Increased population growth results in increasing human needs over time. Meeting the high needs triggered the development of industries that meet the needs. Problems arise from the many industries that emerge, one of which is an environmental problem. Many industries in Indonesia have not used good waste treatment standards, causing pollution from the rest of the production process in the industry, one of which contains heavy metals such as Pb, Zn, Mercury and so on. Heavy metal is a type of pollutant that is harmful to plants, animals and humans through the process of bioaccumulation in the food chain. The purpose of this research is the content of heavy metals that are harmful to the sustainability of ecosystems in the environment requires a long time so that one way to prevent heavy metal compounds that can be released to the environment is by managing the bioremediasi process with fragrant root medicinal plants (Vetiveria Zizanioides) which has hyperaccumulator properties which can absorb one of the heavy metals namely Cadmium (Cd) and Lead (Pb).

Abstract

The increase in population will automatically increase the use of motorized fuel, especially motorbikes and cars. That way, of course the need for fuels such as petrol, diesel, and the like will continue to increase, so there is a need for alternative renewable fuels such as bioethanol which is a renewable fuel that can substitute for these needs. Bioethanol itself is known to have a knock rate value equal to the gasoline and diesel phases when the purity reaches 99.5%. In this study, the characterization process of bioethanol products made from sugarcane juice was carried out using bentonite clay purifiers and looked at the characteristics of pH, brix, and bioethanol content. This research was conducted experimentally, using a completely randomized design (CRD) with 3 treatments, namely variations in the weight of bentonite clay 40 grams, 50 grams, and 60 grams with 3 replications. The results showed that there was an effect of adding variations in the weight of bentonite clay on the bioethanol content of sugarcane juice and there was an effect on the pH value, but there was no effect on the sugar content (brix). The best treatment in this study was bioetano from sugarcane juice with the addition of a weight of 60 grams, with alcohol content production of 9.33%, a pH of 5.13, and 6.33% brix.

Abstract

Amalgamation to gold in artisanal small scale generally uses mercury (Hg) that decrease the quality of environment especially water. A study of mercury artisanal small scale gold mine waste water was conducted by utilizing simple technology using Sub Surface Flow - Constructed Wetland (SSF-CW) system. This system is a combination of phytoremediation methods using Echinodorus palaefolius plant with zeolite as growth media. The purpose of this study was to determine the stability of SSF-CW in reducing Hg concentration in water. This SSF-CW system model has dimensions of 820 mm x 320 mm x 585 mm consisting of 3 zones, namely the inlet zone, the reaction zone and the outlet zone. The study was conducted with an initial HgCl2 waste concentration of 14.94 mg / L which was carried out in two stages, continuous and batch for 12 hours and lasted for 3 days for each stage. Effluent samples were taken every 0 hours, 4 hours, 8 hours, and 12 hours for mercury concentration analysis using Direct Mercury Analyzer (DMA). The result showed that SSF-CW could support the process of reducing Hg concentration n wastewater with removal efficiency of 98.99%. Echinodorus had the ability to accumulate metals with a BCF value of 9,117 and the accumulation of Hg in the zeolite (as growth media) was still far from the saturated capacity to absorb mercury.

Abstract

ndonesian turpentine contains 65-85% α-pinene, 1% camphene, 1-3% β-pinene, 10-18% 3-carene and 1-3% limonene. The largest content of turpentine is alpha pinene. Alpha pinene is also a monoterpene compound that has double bonds and is the main raw material in the perfume industry. In addition, alpha pinene is also an important raw material for the manufacture of fine chemicals that have high sales value such as pine oil, camphor and alpha terpineol. To increase the sale value, alpha pinene can be further processed into derivative compounds such as alpha terpineol and alpha terpinyl acetate. Both are valuable derivative compounds used in the perfume industry and the pharmaceutical industry. Hydration is the reaction between alpha pinene and water to produce alpha terpineol compounds. In the reaction process that will be carried out on alpha pinene usually uses a catalyst that can accelerate the reaction rate without becoming a byproduct, catalyst used in this study is a type of resin. This study aims to study the effect of temperature variables at temperatures of 65, 75, 85 and 950C. The conversion of alpha pinene increases with increasing reaction temperature. Assuming a reversible reaction, the relationship of temperature to each reaction rate constant is determined according to the Arrhenius equation.

Abstract

Urea is an important nitrogen source for plant but the price of urea fertilizer is relatively high. Urea uptake from urea manufacture waste water and its application as fertilizer is of high interest. The purpose of this study is to find out desorption ability of urea adsorbed porous carbon to be applied as fertilizer. Theoritically, urea released from porous carbon to environment has slower rate of mass transfer compare to conventional urea fertilizer because urea molecules in porous carbon has to pass through pores of carbon during its movement out of carbon. The porous carbon as adsorbent was made from coconut shell by pyrolysis, followed by sulfuric acid oxidation treatment Oxidation treatment carried out to extent adsorption capacity as well as to give additional sulfur nutrient when applied as fertilizer. Oxidation of carbon surface was performed using sulfuric acid (50%w) to soak porous carbon followed by heating at 90oC temperature for 2 hours. Desorption was conducted by placing porous carbon into beaker contain water and the raising of urea concentration in water recorded after 3,5,10, 30, and 60 minutes. Results reveal that the value of mass transfer coefficient (kc) and effective diffusivity (De) of urea desorption from porous carbon are 0,0293 – 0,0743 cm/s and 8 x 10-10 – 5 x 10-9 cm2/s with initial concentration of urea 1000, 2000, and 4000 mg/L. Release rate of urea from porous carbon and urea prill are 0,07 ppm/s and 1,23 ppm/s. Slower release rate of urea off porous carbon than urea prill shows the promising of urea recovery using porous carbon as slow release fertilizer.

Abstract

In recent years, more and more oily wastewater has been producing from several industrial areas such as the petrochemical plant, the cosmetic plant, the dye plant, even the food plant which has delivered in solemn environmental problems. One of the splittings to surmount this problem is the supply of advanced technology adsorption, such as membrane technology. The separation process with technology was first present in the 21st centenary. The membrane separation process has got a new technology for oily wastewater treatment due to its upper oil excision efficiency and comparatively easy operation. Some of the fittest methods based on the membrane separation process are dehydration of the oil emulsion by evaporation or flocculation followed by microfiltration or by reverse osmosis, membrane distillation, and ultrafiltration. However, the major problem that frequently occurs in the separation process with membrane technology is membrane blockage (membrane fouling). This journal is a review that depicts the latest expansion in membrane technology such as the membrane technology process and the membrane emulsification process. In addition, the influence of operating parameters on membrane performance is discussed in detail.
