Abstract

Polyethylene terephthalate (PET) is a polyester which is widely used as a container or packaging material, especially mineral water and soft drinks. Recycling is necessary to overcome the post-consumer PET waste PET difficult because degraded naturally. Chemical recycling is an appropriate method for depolymerisation. Glycolysis is the method that is often used as the process was easy. Optimization parameters of glycolysis on the rate of reaction in the efforts to improve the products of glycolysis has been done as the use of catalysts. Metal acetate catalysts such as zinc acetate is a catalyst which shows good activity in the reactions of glycolysis, but the catalyst is non-biodegradable and toxic. The metal oxide catalysts are also many well developed but these catalysts are toxic, corrosive and can cause severe pollution. More environmentally friendly catalysts such as sodium salt today began much developed to minimize the impact to the environment.

Abstract

The energy crisis demands the development of an alternative energy that can meet daily needs. The existence of rice straw biomass waste and corncob is a potential to be utilized as bioenergy in the briquettes form. This research was conducted to develop and test the characteristics of biomass briquettes as alternative fuels. Biomass used in this research is rice straw and corn cob. The making of briquettes is done by carbonation and compaction with starch adhesive by 10%. To know the best quality of briquettes, a mixture of rice straw (100%) was used, mixed rice straw: corncobs (25%: 75%, 50%: 50%, and 75%: 25%), and corncobs (100 %). Test parameters used are ash content, volatile matter content, and calorific value. The results showed that briquettes from corncobs were the best briquettes from ash content and volatile matter content of 9.52% and 9.7% respectively. While based on calorific value, briquettes with highest heating value is rice straw briquettes that is equal to 3562 Kcal / kg but has the highest volatile matter and ash content which can decrease the quality of briquette.

Abstract

Seawater intrusion causes groundwater in coastal areas to be brackish, so it requires special processing to remove salt levels in raw water so that the water becomes tasteless. In addition to salinity, the presence of bacteria in water can cause disease if consumed without proper processing. Brackish water treatment called desalination can be done by ion exchange using an activated carbon filter. The purpose of this study was to determine the efficiency of the performance of brackish water processing filters in setting aside water quality parameters in the form of: coli bacteria and total bacteria expressed in the Total Plate Count (TPC). The filtration reactor is made using filter media in the form of activated charcoal (20cm), silica sand (15cm), zeolite (15cm), and gravel (10cm). laying the reactor upright and tilted 45 degrees. The results showed that the reactor filter was effective in reducing coli bacteria and total bacteria in raw water up to 100% and 97%, respectively, although it did not meet drinking water quality standards PERMENKES No.492 / Menkes / Per / IV / 2010. Both reactor variations have performance effectiveness that is not significantly different in processing raw water, but overall reactors with upright variations have better performance.

Abstract

Waste has become material considered useless anymore. The rate of waste generation continually increase along with the increase of population, making it increasingly threaten the environment. This situation has been exacerbated by the poor handling of the government and society towards waste. Management of waste sources has become an alternative that can be used to handle the waste problem. The community service program has been carried out in the village of Medalem, Tulangan, Sidoarjo to overcome the occurring of waste problem. The public understanding and awareness of waste issues has been improved through the explanation of material, direct practice and the discussion how to process and sort the household waste. The material that has been explained, includes the waste, the classification of the waste based on its nature, and how to manage waste. It was found out that the Community Service program has improved the public understanding of waste, it was shown that more than 65% of participants had answered the questions correctly. The results of the analysis showed that the public attitude and behavior towards waste problems was good. It was supported by the presence of waste facilities that have been provided by the Village Devices.
