Abstract Introduction Audit of waste management in an elective orthopaedic complex was interrupted due Covid-19 pandemic. We investigated the impact of the enforced changes on theatre waste due to Covid-19. Method Over a 1week period data on waste bag availability and number of bags of each category of waste per surgical case in an elective theatre complex was collated; this was compared to waste generated during Covid-19 pandemic. Results Prior to Covid-19 only clinical waste bins were available in many non-dominant clinical areas providing evidence of inappropriate routine disposal of domestic/recyclable waste. Pre-Covid-19 a mean of 6waste bags were used per surgical case (3.7yellow clinical bags, 1.3black domestic bags, 0.4clear recycling bags), with Covid-19 changes to waste management practice the mean number of waste bags used per case increased to 11 (9 orange contaminated bags, 0.5black, 0.3clear bags). Conclusions Clinical waste management has a significant economic and environmental impact. Covid-19 has led to nearly all waste being deemed to be contaminated and so requiring incineration, with increased volumes of waste generated per case through widespread adoption of PPE. This has increased cost and reduced the ability to recycle non-contaminated waste.

Latar Belakang: Pertolongan persalinan yang di lakukan oleh petugas kesehatan (dokter atau bidan) merupakan salah satu faktor resiko penularan penyakit dari pasien ke tenaga kesehatan atau sebaliknya karena berhubungan langsung dengan cairan tubuh pasien. Proporsi persalinan yang ditolong oleh bidan yaitu 60,9% dibandingkan dokter 16,2%. Mengingat bahwa infeksi ditularkan melalui darah, sekret vagina, air mani, cairan amnion dan cairan tubuh lainnya maka hal tersebut mempunyai resiko untuk tertular bila tidak mengindahkan pencegahan infeksi.Tujuan: mengetahui gambaran pelaksanaan pencegahan infeksi pada pertolongan persalinan dibidan praktik mandiri Kota Banjarmasin.Metode: Metode penelitian ini bersifat deskriptif. Populasi berjumlah 112 bidan praktik mandiri. Cara pengambilan sampel dengan simple random sampling dengan jumlah 35 bidan praktik mandiri. Analisa data dengan menggunakan analisa univariat.Hasil: Melakukan prosedur cuci tangan sebanyak 35 responden (100%), sarung tangan dtt/steril 35 responden (100%), apron/celemek 35 responden (100%), masker 35 responden (100%), kacamata google 7 responden (20%), tutup kepala 20 responden (57,1%), sepatu boot 17 responden (49%), melakukan tindakan aseptik 35 responden (100%), penanganan benda tajam dengan aman 35 responden (100%), cara pemprosesan alat bekas pakai 35 responden (100%), pengelolaan sampah terkontaminasi 35 responden (100%), membersihkan lantai dan ruangan dengan klorin 0,5% sebanyak 35 responden (100%).Simpulan: Pencegahan infeksi pada pertolongan persalinan dibidan praktik mandiri kategori baik sebanyak 27 responden (77,1%) dan dengan kategori kurang baik sebanyak 8 responden (22,9%).                                                                                        Kata Kunci: Praktik Mandiri Bidan, Pencegahan Infeksi, Penggunaan Instrumen, Pertolongan Persalinan Prevention Of Infections In Relief Treatment In Practice Midwife Independent BanjarmasinABSTRACTBackground: Delivery aid performed by health workers (doctors or midwives) is one of the risk factors disease transmission from patient to health worker or vice versa because it is directly related to patient's body fluid. The proportion of births assisted by midwives is 60.9% compared to doctors at 16.2%. Given that blood-borne infections, vaginal secretions, semen, amniotic fluids and other body fluids are at risk of contracting if they do not heed infection prevention.Objective: Knowing the description of the implementation of infection prevention in delivery aid midwife independent practice Banjarmasin city.Method: This research method is descriptive. Population there are 112 independent practice midwives. Sampling method With simple random sampling with 35 independent midwives practice. Analysis using univariate analysis.Result: Perform handwashing procedures 35 respondents (100%), DTT / sterile gloves 35 respondents (100%), apron 35 respondents (100%), mask 35 respondents (100%), google glasses 7 gespondents (20 %), head cover 20 respondents (57.1%), boots 17 respondents (49%), aseptic actions 35 respondents (100%), safe handling of Sharps 35 respondents (100%), contaminated waste management 35 respondents (100%), cleaning floor and room with 0.5% chlorine as many as 35 respondents (100%).Conclusion: Prevention of infections at birth assistance in practice self-esteem good category as many as 27 respondents (77.1%) and with bad category as many as 8 respondents (22.9%). Keywords : Independent Midwives, Labor Help, Prevention Of Infection, Use Of Instrument

Bioremediation technologies are one of the novel methods in the field of waste and environment management and are presently gaining immense credibility for being eco-compatible. Bioremediation using microbes has been well accepted as an environment friendly and economical treatment method for disposal of hazardous petroleum hydrocarbon contaminated waste (oily waste). Besides this, earthworms can be used to extract toxic heavy metals, including cadmium and lead, from solid waste from domestic refuse collection and waste from vegetable and flower markets. Other novel methods used recently for treatment of wastes are plasma incineration or plasma assisted gasification and pyrolysis technology. The technologies applied for conditioning include ultrasonic degradation, chemical degradation, enzyme addition, electro-coagulation and biological cell destruction. Genetic engineering is another method for improving bioremediation of heavy metals and organic pollutants. Transgenic plants and associated bacteria constitute a new generation of genetically modified organisms for bioremediation.
