PURIFIKASI DAN UJI DEGRADASI BAKTERI MIKROPLASTIK DARI PERAIRAN MUARA SUNGAI MUSI, SUMATERA SELATAN

Kepadatan limbah plastik menjadi suatu ancaman besar bagi lingkungan dan organisme perairan, pasalnya proses degradasi plastik menjadi mikroplastik membutuhkan waktu yang sangat lama. Salah satu upaya alternatif untuk mengurangi dampaknya dapat menggunakan bakteri.  Penelitian ini bertujuan untuk  mengidentifkasi jenis bakteri pendegradasi limbah mikroplastik dan menentukan kemampuan isolat bakteri dalam mendegradasi limbah mikroplastik. Penelitian ini dilaksanakan pada bulan Juli – September 2019. Pengambilan sampel air menggunakan jaring micro nett berdiameter 90x15 cm dengan mesh size 300 ?m dan dilakukan pengukuran kualitas air, meliputi suhu, salinitas, DO, pH dan kecepatan arus. Identifikasi bakteri menggunakan uji biokimia otomatis (VITEK-2). Hasil penelitian menunjukkan adanya tiga jenis bakteri yang berpotensi mendegradasi mikroplastik dari enam isolat yang berhasil dimurnikan yaitu Vibrio fluvialis, Serratia rubidaea, Serratia marcescens dan Psedomonas putida.Kata Kunci : Bakteri mikroplastik, degradasi, kualitas air, Muara Sungai Musi

Effectiveness of a stunting recovery program for children treated in a specialized center

BACKGROUND: Stunting is still very prevalent in many poor and developing regions in the world. This study assessed the effectiveness of a stunting recovery program in children and its associated factor. METHODS: The retrospective study was conducted in a center of stunting recovery. There, children stayed in a day hospital system (9h per day5 days per week), and received five meals per day, pioviding 80% of their energetic daily needs. The main outcome was the stunting recovery rate (i.e., the child present a height for age index (HAZ) > - 1.0 at the time of data collection). A total of 75 children treated for at least 24 months, aged between 6 and 48 months and with an HAZ 24 months" (prevalence rate (PR) = 0.39, 95% confidence interval (Cl): 0.15-0.99P = 0.04) and the variable "Household crowding index" (PR = 0.65, 95% Cl: 0.44-0.95, P = 0.03) were associated with the success of the treatment. CONCLUSION: The environmental conditions in which the children live in their households and late admission to the center negatively influenced the success of stunting recovery, even with an intensive treatment.Univ Fed Alagoas, Fac Nutr, Ctr Recuperacao & Educ Nutr, Cidade Univ, Maceio, BrazilUniv Fed Sao Paulo, Dept Fisiol, Sao Paulo, BrazilUniv Fed Sao Paulo, Dept Fisiol, Sao Paulo, BrazilWeb of Scienc
