Studi Penelusuran Lulusan Prodi S1 Pendidikan Tata Busana Fakultas Teknik Universitas Negeri Surabaya

Abstrak Tracer Study pada Prodi S1 Pendidikan Tata Busana merupakan metode yang digunakan pada perguruan tinggi terutama di Universitas Negeri Surabaya yang digunakan sebagai penghubung antara instansi dan stakeholder  untuk mengetahui dan menggali beberapa informasi dalam memperoleh umpan balik (feedback) dari alumninya.  Umpan balik (feedback) digunakan sebagai bahan perbaikan sistem dan pengelolaan serta  menggali informasi terkait keberadaan alumni. Kegiatan tracer study dilaksanakan dengan  memberikan pemetaan antara lulusan yang bekerja di berbagai instansi. Keterserapan alumni merupakan bagian dari  persentase keberhasilan alumni untuk masuk di dunia kerja sesuai dengan bidang kompetensi yang diperoleh selama melaksanakan studi di perguruan tinggi. Lulusan/alumni dari Prodi S1 Pendidikan Tata Busana yang   memiliki pengetahuan, dan keterampilan yang akan dibutuhkan pada saat memasuki dunia kerja, baik itu bekerja pada instansi pemerintahan, swasta maupun berwirausaha. Hasil Tracer Study Program Studi S1 Pendidikan Tata Busana  telah menunjukkan bahwa karakteristik lulusan bekerja di bidang pendidikan dan berwirausaha. Sebanyak 23, 3% bekerja sebagai guru atau tenaga pengajar. 41, 7% para alumni bekerja secara mandiri yaitu dengan berwirausaha dan sesuai dengan bidang keahliahnya, selebihnya bekerja pada sektor bidang pekerjaan lain. Waktu tunggu lulusan program Studi S1 Pendidikan Tata Busana menunjukkan bahwa  73% sebelum mereka lulusan kurang dari 3 bulan setelah lulus sudah mendapatkan pekerjaan, artinya tidak perlu menunggu lama bagi lulusan program studi S1 Pendidikan Tata Busana untuk mendapatkan pekerjaan pertamanya Kata Kunci: Tracer study, Lulusan, Jenis Pekerjaan

Removal of Synthetic Dyes from Aqueous Media Using Biocomposites

Wastewater which is produced from different textile industries is also the major cause of water pollution. In present research work, the optimum conditions of biosorption experiments for the elimination of synthetic dyes were determined by doing batch and continuous study. The optimum pH for getting the maximum biosorption of four selected acid dyes (ADG-180, AO-RL, ANB N-RBL and ATB E-2G) was observed in acidic range (2-6) while the 0.05 g/50 mL biosorbent dose (PPy/SB, PAn/SB, PPy/Ch, PAn/Ch, PPy/St and PAn/St; PPy/RH, PAn/RH, PPy/Ch, PAn/Ch, PPy/St and PAn/St; PPy/PH, PAn/PH, PPy/Ch, PAn/Ch, PPy/St and PAn/St andPPy/CS, PAn/CS, PPy/Ch, PAn/Ch, PPy/St and PAn/St ) was determined as optimum dose for the removal of all four selected acid dyes respectively. The equilibrium was attained within 45-60 min for all selected biosorbents for the elimination of selected acid dyes. The optimum initial dye concentration was observed in 125-150 mg/L range to get maximum acid dyes elimination using different types of selected biosorbents. The optimum temperature for getting maximum removal of all selected acid dyes was observed as 30 ºC and reduction in biosorption potential of all biosorbents was investigated by temperature rise. It showed the exothermic nature of all biosorption processes that engaged in elimination of selected acid dyes. Langmuir and Freundlich biosorption equilibrium isotherms showed satisfactorily fitness on biosorption data where as the pseudo-first-order and pseudo-second-order both demonstrated satisfactory fitness on experimental kinetic data. Various thermodynamical parameters were determined to know about nature and feasibility of biosorption. Biosorption capability of selected efficient biosorbents for their respective acid dyes was reduced significantly by surfactants/detergents presence in acid dye solution. Maximum desorption was achieved using 0.5 N NaOH. In column study; 3 cm, 70 mg/L and 1.8 mL/min were observed as optimum bed height, inlet initial dye concentration and flow rate for attainment of highest biosorption of ADG-180, AO-RL, ANB N-RBL and 90 mg/L for ATB E-2G dye. The biosorption study of real textile effluents was also carried out for the application of this technology on practical scale. The characterization ofprepared biosorbents was done by FT-IR, thermal analysis and SEM which provided significant information about thermal stability, active binding functional groups and surface morphology.
