Warna pada limbah cair indusri tekstil dihasilkan berasal proses pewarnaan. Limbah cair yang berwarna ini jika di buang langsung akan menghambat proses transfer oksigen dibadan air. Tujuan dari studi literatur ini adalah mengetahui waktu kontak dan media penyerap yang terbaik pada metode adsorpsi, filtrasi dan elektrolisis dalam pengolahan warna pada limbah cair industri tekstil. Metode adsorpsi, filtrasi dan elektrolisis adalah metode yang sering digunakan pada pengolahan warna pada limbah cair industri tekstil. Berdasarkan studi literatur yang telah dilakukan didapatkan hasil waktu kontak optimum dan media penyerap yang terbaik pada metode adsorpsi menggunakan media penyerap biosorben selama 30 menit mampu menyerap warna dengan efesiensi penyerapan 99,9%, metode filtrasi menggunakan media penyerap membran nanofiltrasi selama 480 menit mampu menyerap warna dengan efesiensi penyerapan 99,9% dan meode elektrolisis menggunakan media penyerap elektroda PbO2, Al, C selama 120 menit mampu menyerap warna dengan efesiensi penyerapan 99,78%.

The development of the property industry is very influential on the agricultural sector. Gampingrowo Village is an area where most of the people earn their living from agriculture. This relates to the availability of land if the land is used for the property industry. One alternative to overcome the limitations of agricultural land is to apply agricultural cultivation technology with the hydroponic method. The purpose of this service is to provide youth with skills, knowledge about hydroponics. This training method is carried out by providing counseling on hydroponic methods in general and training participants practice to assemble simple starter kits. Participants 25 people were divided into 3 groups where each group got 2 starter kit packages. The results of this dedication were that the participants were very enthusiastic and eager to know more about the hydroponic method with a few questions and they were very happy because the starter kit could be taken home
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
