Abstract

The term acid rain refers to the deposition of the atmosphere containing acidic compounds that fall to the earth in the form of rain, snow, particulates, gases and vapors and have a negative impact on the earth. Acid rain was first introduced by Ducros (1845) and later described by the English chemist Robert Angus Smith (1852) whose research studies linked the sources of acid rain to industrial emissions and included early observations of the damaging environmental effects. This article summarizes the scope of acid rain by providing the latest scientific advances on how emissions, deposition, and temporal trends of the pollutants that cause acid rain vary around the world. Considerable progress in reducing SO2 and NOX emissions is evident throughout North America and Europe. In contrast, the decline in SO2 started only about 10 years ago in China and the decline in NOX emissions only in the last few years. While in other parts of Asia such as India, these emissions continue to increase. Investigations of chemical contaminants in surface water, soil, fish, and vegetation show that recovery is slow and will unfold over decades as emissions and depositions continue to decline. Whether the affected ecosystems will return to their current acid rain conditions is uncertain and will likely depend on many other factors such as human disturbance and natural disasters and climate change. Gaining a better understanding of how acid rain interacts with various factors that affect ecosystem trajectories remains a challenge for the scientific community to address.

Abstract

Waste’s dynamic problem will always be present in humans life and even get increasing each day. Waste generated from various kind of human activities and it will cause serious problem if it is not handled properly. One among many waste types which mostly produced from humans daily activities is organic waste and the concrete example is vegetable trash. Vegetable trash generated in large amount everyday that the treatment of this trash is important to be carried out. Also, vegetable trash is a source of biomass which can be converted into renewable energy source, that is biogas. This research aims to collected literature references (review) of vegetable trash conversion into biogas by adding with cow dung and draw conclusion about optimum composition of mixture of cow dung and vegetable trash which obtain highest methane gas (CH4) concentration. Cow dung is known as potential biogas raw material for its high cellulose content after digested in cow’s stomach that its is easier broken down by methane composing bacteria in methanogenenis process to produce methane gas (CH4). The variables used in this research are mass ratio between cow dung (KS) and vegetable waste (SS) variation of 100:0; 75:25; 50:50; 25:75; and 0:100 with addition of EM4. Literature review give conclusion that optimum composition mixture in biogas production process is 70% cow dung and 30% vegetable trash.

Abstract

Utilization of biogas sludge waste from cow dung into briquettes is an alternative to reduce the use of fossil fuels. In the manufacture of briquettes made from biogas sludge, molasses is used as an adhesive which is a by-product of a sugar factory. In this study, variable compression briquettes with variations of 10, 15, 20, and 25 mm were used and further testing was carried out on the moisture content, ash content, and calorific value of the briquettes. The effect of briquette compression on the water content of the best briquettes according to the SNI standard (less than 8%) is at 10 mm compression variation with a moisture content value of 6.03%. Meanwhile, the effect of pressing briquettes on the ash content and calorific value is still above the SNI standard and requires further study.

Abstract

Plastic is a polymer compound whose main constituent elements consist of carbon and hydrogen where one of the raw materials that is often used to make plastic is naphtha, which is a material produced from refining petroleum or natural gas (Surono, 2013). Chemical decomposition through a heating process without oxygen where the raw material will undergo a breakdown of the gas phase structure called pyrolysis (Jahiding et al., 2020). The quality comparison of pyrolisis oil, kerosene and oil, namely pyrolysis oil is lower than the quality of kerosene but higher than diesel oil based on density oil, duration of combustion, water temperature and volume of water that evaporates. Based on the research that has been done by Wahyudi (2018) and Mustam (2021) which is shown from the comparison chart of kerosene, pyrolysis oil and diesel oil based on the density of oil, duration of oil burning, temperature of cooked water and vaporized water volume. The quality of kerosene is better when compared to pyrolysis oil and diesel oil which is determined by the flash point of kerosene which is lower between pyrolysis oil and diesel oil, which is 47.8 oC. The flash point of diesel oil is 55 oC (the data on the flash point of kerosene and diesel oil were obtained from the Ministry of Energy and Mineral Resources in 2006). While the point of pyrolysis oil can be under the range of more than 47.8 oC and less than 55 oC. This is because the quality of pyrolysis oil is between kerosene and diesel oil.

Abstract

Air pollution requires proper handling so that the impact can be reduced. Nipah fruit shell contains high cellulose and lignin so that carbon from nipah fruit shell needs to be implemented as an adsorbent to reduce the concentration of Hydrogen sulfide (H2S) gas produced from fish waste. The purpose of this study was to determine the characterization of carbon from nipah fruit shells as H2S gas absorbers with the effect of time variations of 10 minutes, 15 minutes and 20 minutes. The method of absorption of H2S absorption using iodine absorption with iodometric titration. The sampling process went through several stages, such as the carbonization process, carbon characterization process, and H2S gas adsorption using carbon that had been characterized by water content and iodine absorption. This research resulted in the production of carbon from nipa palm shell as an H2S gas absorber which has a water content characterization of 1.0651% and an iodine absorption capacity of 615.6105 mg/g so that it can adsorb H2S gas with an initial concentration of 64 ppm until it reaches the lowest concentration of 5.538 ppm.

Abstract

Cilacap State Polytechnic chemical laboratory has waste derived from the disposal of practicum and testing activities that use hazardous and toxic materials or chemicals. Adsorption process with the addition of preparation bentonite and bamboo charcoal with bambusa vulgaris var type. striata or yellow bamboo. Activation of bamboo (Bambusa vulgaris var. striata) chemically using a solution of 10% H3PO4 (phosphoric acid). Chemical activation of bentonite by mixing bentonite with a 5% HCl solution. This study aims to find out the decrease in concentrations of Total Dissolved Solid (TDS) and Total Suspended Solid (TSS) in the liquid waste treatment of Cilacap State Polytechnic chemical laborator. Chemical activation of adsorbents decreased the concentration level of Total Dissolved Solid (TDS) by 88.793% and decreased concentration of Total Suspended Solid (TSS) by 84%. The trapping capacity of yellow bamboo adsorben material (Bambusa vulgaris var. striata) with 10% H3PO4 chemical activation and bentonite with 5% HCl chemical activation can trap total dissolved solid (TDS) adsorent capacity levels of 6,866 mg/g and Total Suspended Solid (TSS) absorption capacity of 0.0875 mg/g. Utilization of bentonite and yellow bamboo waste (Bambusa vulgaris var. striata) can be used as an effective adsorbent material in the processing of chemical laboratory liquid waste.
