Purple sweet potato (Ipomoea batatas L.) is one of the tubers or roots that is widely grown in Indonesia that contain high antioxidants. One type of flavonoid that functions as an antioxidant is a natural dye called anthocyanin. In the process of extraction of anthocyanin, the solvent has an important role. In this research, the deep eutectic solvent was used because it is more economical and environmentally friendly. This research will optimize the microwave assisted extraction of anthocyanin content in purple sweet potato (Ipomoea batatas L.) using a deep eutectic solvent with the variation of material to solvent ratio, microwave power, and extraction time. Optimization is done by using the statistical method Response Surface Method (RSM) with Total Anthocyanin content as a response. The optimum operating conditions for the extraction of anthocyanins from purple sweet potato using the deep eutectic solvent were obtained at a solid to solvent ratio of 1:29 at a microwave power of 270 watts for 193 s, with an optimum TAC value of 311.64 mg/L and an antioxidant value of 44.85%. The use of DES can increase the extraction yield and is environmentally friendly.

The strategic plan for the development of the Semaki area is to develop regional-based economic, social and cultural communities with various training programs. One of which is handmade batik craftsmen who is in UKM Balai Agung Cendana Batik Tulis. The problems are high production costs and the length of production time in making batik. The purpose is to increase the knowledge and capacity of partners in producing batik with natural dyes by introducing natural dyeing technology so as to reduce the stages of the process so as to reduce production costs. Methods and approaches in implementing this activity are counseling and training. Community service activities at Balai Agung Cendana Batik Tulis were able to increase participants' knowledge in drawing motifs, wax painting, dyeing processes, and pre-mordanting with chitosan up to 100%. The batik training provided to the community was also able to improve the community's skills in drawing and painting batik up to 92% and the skills of dyeing fabrics with natural dyes and chitosan mordanting up to 98%.

Pengelolaan dan Pengolahan Sampah Organik di Dukuh Sanan, Kabupaten Bantul Rachma Tia Evitasari; Dinan Yulianto; Firda Mahira Alfiata Chusna

Dukuh Sanan terletak di Provinsi Daerah Istimewa Yogyakarta, Kabupaten Bantul, Kecamatan Pleret, dan Kelurahan Bawuran. Mayoritas pemuda di Dukuh Sanan tergabung ke dalam karang taruna yang berperan aktif memilah sampah botol plastik dan plastik bening untuk dijual dengan nilai ekonomis yang rendah. Hal ini suatu rintisan yang baik tetapi belum mengakomodasi ketegori sampah lain. Program pengabdian ini berupaya meningkatkan ilmu pengetahuan pemuda karang taruna Dukuh Sanan selaku mitra dalam mengelola dan mengolah sampah organik menjadi pupuk kompos. Metode pelaksanaan pengabdian masyarakat ini terdiri dari tahap pra-pelaksanaan, pelaksanaan, dan pasca-pelaksanaan. Tahap pra-pelaksanaan berupa persiapan dan sosialisasi kegiatan. Tahap pelaksanaan meliputi penyuluhan pemisahan jenis sampah organik dan anorganik, pelatihan pengelolaan sampah dengan prinsip 3R (reduce, reuse, dan recycle), dan pelatihan pembuatan pupuk kompos dari sampah organik. Para peserta mengikuti kegiatan dengan sangat antusias dan berhasil membuat produk berupa pupuk kompos. Tahap pasca-pelaksanaan dilakukan evaluasi peningkatan pengetahuan mengenai pembuatan pupuk kompos sebesar 93%.

Natural dyes are alternatives to synthetic dyes as batik dyes. However, color results produced by natural dyes were not as good as synthetic dyes, hence mordant compounds were required. As a substitute for metal mordant, it was essential to have another alternative mordant, such as chitosan. This research was intended to analyze the color produced by various sources of natural dyes, betel nut; spurred mangrove (tingi) bark; baheda (jolawe) peel; mangrove bark; mahogany bark; and copperpod (jambal) bark, quantitatively by testing the value of color differences (ΔE) on variations of the chitosan concentration and fabric dyeing. In conclusion, the use of chitosan could enhance the absorption of dye into the fabric. In a chitosan concentration of 10 g/L, betel nut reached an ΔE value of 15.40; spurred mangrove 16.26; baheda peel 18.97; mangrove 10.87; mahogany 14.01; and copperpod 19.33. Furthermore, the test of fastness to sunlight with greyscale showed the value in range of 4-5 (good).

Yogyakarta is one of the largest batik-producing cities in Indonesia. It has a positive impact on the artisans's economy. It adds new jobs, but this has yet to be matched by the skills and knowledge of the artisans in managing liquid waste generated from batik activities. So far, liquid batik waste has been stored in holding tanks and allowed to seep into the ground or even directly thrown into the water without further processing. So, it harms the environment, such as pollution of the waters and the surrounding environment and even the death of aquatic biota. Therefore, a renewable technological innovation was created, combined with the Heterogeneous Fenton method as a medium for processing batik waste. The methods used include pre-test, lecture, question and answer and post-test. Based on service activities that have been carried out, including providing information on equipment technology of batik waste processing to batik artisans in Desai Iroyudan, Guwosari Village, Pajangan District, Bantul Regency, Yogyakarta, it is known that the level of community understanding has become 98% or increased by 23%.
