Abstract

The existence of the textile industry in Indonesia is not only in the category of large and medium scale industries but also in small scale and some even in the home industry. These caused pollution mainly as a result of the dyeing of textiles. Dye not only occurs in industrial areas but also occurs in densely populated settlements. An attempt to treat the waste of the textile industry is needed to solve the environmental pollution. In this research, liquid waste was processed using the electrocoagulation method, and the expected concentration or hazard caused by waste was decreased and to fulfill the required environmental quality standard. Treatment of jumputan wastewater by electrocoagulation method using 4 aluminum electrodes 11x10.5 cm in size with MP-P configuration type (Monopolar-Paralel) for 120 minutes. The parameters measured in this study were chromium heavy metal content, TSS (Total Suspended Solid), TDS (Total Dissolved Solids), as well as changes in pH, color and turbidity values where the applied voltage variations were 10, 13, 15, 17, and 20 volts with variation of electrode distance used 1.5; 2.0; and 2.5 cm. The best condition for each parameter was obtained at a distance of 1.5 cm with a voltage of 20 volts. Effectiveness of electrocoagulation method to decrease turbidity value up to 99.84%; color 99.33%, chromium content of 62.5%; TSS 33.68%; TDS of 66.59% and raised the pH from 5.64 to 8.10, respectively.

Abstract

The increase in population has increased the need for fuel oil and gas, our fossil energy reserve is increasingly decreasing, while its needs continue to increase. This fact opens up a chance to use renewable energy and reduce the use of fossil fuels. In addition to the depletion of the number of fossil fuels, other important reasons for reducing its use are environmental damage issues, ongoing prices, and greater subsidization burden. To overcome the situation, can be pursued in two ways. First reducing the level of consumption and both continue to develop other alternative energy sources, especially renewable energy sources. Lately emerged various findings. Ranging from cassava, sweet potatoes, to corn that is processed into bioethanol. But on its way, the development of the fuel is often burp. The clash with food needs is one of the challenges. While the crop fails and the land needed to be another problem that cannot be underestimated, especially amid the issue of global warming. BioEthanol itself is processed from carbohydrates or starch contained in natural materials. During this time bioethanol is produced by many food crops such as corn, cassava, and sweet potatoes. In fact, these materials are still needed as a support for foodstuffs. Through this study, the author lifted the green algae (Cladophora sp) as one of the alternative solutions in the production of bioethanol which can someday become an alternative fuel. This is because green algae (Cladophora sp) are scattered everywhere and the Carbohydrates content is quite high i.e. 52.54-60.98% (Khuantrairong et al., 2011). In this research researchers utilize the green algae to produce alternative fuels by looking at how the H2SO4 solvent concentration affects the resulting product.

Abstract

The development of micro, small and medium enterprises (MSMEs) is the basis of the economy in improving the national economic rate because most of the existing businesses in Indonesia are small and medium enterprises. Among those small and middle enterprises, Palembang Jumputan Textile has its own characteristics in patterns and colors. Under the influence of a certain pattern, Jumputan Textile has been known and spread in Sumatra and even in Indonesia and overseas. Nowadays, the regional pattern in every province has been in the fast track of development nationally. The creative industry in Palembang is including around 300 industries of Songket and Jumputan Textile recorded in this city. Community service activities have been conducted to two small and medium enterprises in the center of Palembang Jumputan Textile. The community activities are including the development of pattern making or motif on fabric, dyeing process, and online marketing technique in attempt to improve the sales.

Abstract

The increment of Songket popularity as the traditional fabric from South Sumatra increases the production of Songket and the wastewater produced during the dying process. The dying process produces the reddish wastewater, and if it is disposed of directly into the environment, it will have a negative impact on the waters. The wastewater treatment of this reddish liquid is by electrocoagulation method. Electrocoagulation method is contaminants removal by electrical and chemical treatment system. The electrocoagulation method in this research was conducted in a batch where the wastewater was treated using 16.5 x 7.0 x 0.2 cm aluminum electrode. The parameters varied were the current density and processing time to determine the pH value, color intensity, BOD5, COD, TSS, and phenol levels. The optimum condition obtained from this study at a current density of 25 A/m2 with a processing time of 160 minutes. The effectiveness of Songket wastewater electrocoagulation was 67.28% for TSS, 54.13% for BOD5, 63.64% for COD, color intensity 79.21% and phenol content of 74.93% respectively. The result has fulfilled the quality standard of textile industry wastewater treatment.
