<![CDATA[The textile industry including batik has provided broad benefits to society from an economic standpoint. However, there is negative impact from wastewater generated in the production process, which is containing dyes. Various types of dyes are used in the coloring process, and methylene blue is one of most used dye. Various ways have been done to treat wastewater containing methylene blue. Methylene blue processing techniques by adsorption have been carried out with various types of adsorbents. Research on the comparison of the ability of commercial activated charcoal and commercial activated zeolite to adsorb methylene blue was carried out with the addition of an Fe catalyst and a hydrogen peroxide oxidizer. The results showed that the addition of Fe catalyst would increase the degradation of methylene blue in the waste either with activated charcoal or activated zeolite. The combination of using Fe catalyst and hydrogen peroxide oxidizer further increases the removal of methylene blue in both types of adsorbents, activated charcoal and activated zeolite. Activated zeolite has the better ability to adsorb methylene blue than activated charcoal under various conditions.]]>

<![CDATA[The development of the tannery industry in addition to being beneficial for the economic growth of the community also has a negative impact on the environment due to the disposal of waste produced. Components of waste produced from the leather tanning industry include residual protein and fat, surfactants, anti-bacterial, anti-fungal, coloring and tanning agents. One component that is found in surfactants and often pollutes waters is alkyl benzene sulfonate and linear alkyl benzene sulfonate surfactants. Alkyl benzene sulfonate (ABS) is an anionic surfactant that has a very long and branched carbon chain that is difficult to degrade by microorganisms in nature. Characterization and testing of the activity of porous/activated carbon catalysts will be carried out. The type of porous activated carbon used is coconut shell carbon with microspores character. The stages of this research consisted of the process of impregnation of iron oxide on porous carbon, the surfactant waste degradation process and the characterization of the catalysts produced. Based on the research that has been done, it can be concluded that the catalyst Fe2O3/coconut shell activated carbon is very effective to be applied for the degradation of surfactant waste. The degradation capacity of surfactant wastes increases with increasing concentration of active site Fe. The capacity of the surfactant waste degradation reaction using coconut shell catalyst at t = 3 hours for variations in the concentration of Fe 2%, 4% and 6% respectively 6.77 mmol/gram catalyst, 3.18 mmol/gram catalyst and 1.61 mmol/gram catalyst. The data show that the surfactant waste degradation reaction capacity increases with the increase in the composition of iron oxide added to the surface of the porous carbon support.]]>

<![CDATA[The colorant that is often used in the textile industry is methylene blue which is a cationic heterocyclic aromatic compound. This compound is very stable and is difficult to decompose naturally leading to environment in large concentrations. Therefore, a waste treatment technology to reduce the concentration of dye waste in water becomes importannt. So far, adsorption method with activated carbon remains the most efficient and effective technique in removing dyes from liquid waste due to its relatively large adsorption capacity. Activated carbon is one of the non-metallic mineral commodities or multipurpose industrial minerals, one of which is as an adsorbent or adsorbent media. This study aims to determine the potential of activated carbon in adsorbing methylene blue with variations in the concentration of methylene blue and particle size of activated carbon. The procedures in this experiment include, the preparation of activated carbon with size variations (20-60, 60-100 and> 100 mesh) and variations in the concentration of methylene blue (15 ppm, 30 ppm and 45 ppm) with contact time (0 to 180 minutes). From the results of the study, it was found that the smaller the size of activated carbon used, the greater the adsorption capacity, ie at mesh size> 100 mesh, the adsorption capacity was 9.8%. Whereas, the smaller the concentration of methylene blue, the activated carbon could work optimally at a concentration of 15 ppm at 30 minutes with adsorption capacity as high as 100%.Keywords: adsorption; Methylene Blue; activated carbon; concentration; time; particle size]]>

<![CDATA[The use of dyes in the textile industry has a negative impact, namely water pollution if the waste is discharged directly into the river or not treated properly. Liquid waste from the textile industry generally still contains dyes that are harmful to living things and the environment. In this study the dye adsorption method was used by using modified activated carbon from the coconut shell with the addition of the active site Fe2O3. Characterization and activity testing of iron / porous oxide activated carbon adsorbent will be carried out. The type of porous activated carbon used is coconut shell carbon with micropore characters. The stages of this study consisted of the impregnation process of iron oxide on porous carbon, the methylene blue adsorption process and the characterization of the resulting adsorbent. Based on the research that has been done, it can be concluded that the adsorption of Fe2O3 / coconut shell activated carbon is very effectively applied for the absorption of dye wastewater. The adsorption capacity of methylene blue increased with increasing concentrations of loading of active sites of Fe and the percentage of adsorption capacity in the 180 minute reaction was 89.8% with the loading of iron oxide / coconut shell adsorbent 2%. In addition, from the results of the adsorbent activity test with variations in the mass addition of the adsorbent it can be concluded that the mass increase of the adsorbent significantly affected the yield of blue methylene adsorption.]]>

<![CDATA[Perkembangan populasi masyarakat Indonesia sedemikian pesat sehingga menimbulkan berbagai dampak baik positif maupun negative. Salah satu dampak negative yang ditimbulkan akibat pertumbuhan penduduk adalah sampah. Setiap rumah tangga menghasilkan sampah yang tidak sedikit jumlahnya. Beban pengelolaan sampah saat ini tergantung pada Tempat Pembuangan Akhir (TPA) di masing-masing daerah. Sehingga hal ini menimbulkan dampak sosial dan lingkungan yang cukup serius. Masalah sampah tidak hanya terdapat di wilayah perkotaan namun telah sampai pada wilayah pedesaan. Masyarakat pedesaan biasanya membuang sampah langsung ke sungai atau membakarnya di kebun mereka. Pola kebiasaan tersebut dapat menimbulkan pencemaran udara maupun lingkungan perairan. Oleh karena itu, pengabdian ini bertujuan untuk mengedukasi masyarakat agar dapat memilah sampah menurut jenisnya sehingga tahap selanjutnya sampah tersebut lebih mudah untuk diolah menjadi barang yang bernilai jual. Berdasarkan jenisnya sampah dibagi menjadi 2, yaitu sampah anorganik dan sampah organik. Sampah anorganik yang dihasilkan dalam rumah tangga antara lain, botol, plastik kemasan makanan maupun minuman. Sedangkan sampah organik yang dihasilkan rumah tangga seperti, sisa sayur, sisa buah maupun sisa makanan. Dalam pengabdian ini masyarakat diberikan penyuluhan dan pelatihan mengenai cara memilah dan mengolah sampah anorganik maupun organik. Sampah anorganik dioleh menjadi ecobrick sedangkan sampah organik diolah menjadi pupuk cair. Hasil pengabdian ini adalah dapat menambah wawasan dan merubah pola penanganan sampah di masyarakat agar lebih peduli terhadap kelestarian lingkungan. Selain itu teknologi sederhana dan ramah lingkungan sehingga masyarakat dapat mengaplikasikan langsung untuk mengolah sampah rumah tangganya secara mandiri. Â Â Â ]]>

<![CDATA[Consumption of fruit is highly recommended to keep the body healthy. In line with increasing public awareness of fruit consumption, the amount of fruit waste also increases. One way to reusing fruit waste is to convert it into liquid organic fertilizer (LOF). A group of female senior citizen (PKK) from Murtigading Village, Sanden, Bantul participated a workshop on making LOF reactors in the form of stacked buckets as an effort to convert fruit waste into plant fertilizer. LOF is made from fruit waste that is put into a stacked bucket reactor. The entire process takes two months to produce leachate, which is then aerated for one month before being used. The participants were pleased about the workshop and learned about the benefits of LOF 80% and how to make LOF 84%. ]]>

<![CDATA[The low quality of groundwater, along with the increasing demand for drinking water for the community, encourages the need for water treatment technology to produce quality drinking water that is environmentally friendly. One promising method to be applied is membrane technology. In water treatment systems, membrane technology is often not used alone but combined with other methods to improve water quality more effectively. This study aims to apply several methods for the raw water treatment system to drinking water, including membrane filtration and UV irradiation. The removal of chemical pollutants was investigated and compared to the standard value from Minister of Health Regulation No. 492 Year 2010 for drinking water quality. This coupled treatment successfully improved the water quality. The concentration of chemical and biological pollutants such as total dissolved solids (TDS), Fe, Zn, Pb, and total Coliform were reduced by 58.53%; 43.48%; 88.89%; 66.67%.; and 86.15%, respectively. The results indicate that coupling microfiltration membrane to UV irradiation method can be an effective treatment to remove chemical pollutants and enhance the quality of raw water for drinking water preparation.]]>
