ATMK merupakan salah satu industri kecil menengah (IKM) yang juga menjalankan optimasi metode kerja. Penanganan material oleh IKM sebagian besar dilakukan secara manual sehingga dikhawatirkan akan mempengaruhi kesehatan dan keselamatan kerja karyawan. Hal tersebut dapat diatasi dengan melakukan analisis postur kerja karyawan (operator) dengan menggunakan metode quality exposure check (QEC). Penelitian diawali dengan mengamati postur kerja operator setiap stasiun kerja, pengumpulan data dengan pengisian lembar kuesioner oleh observer dan operator. Langkah berikutnya merekapitulasi data kuesioner dalam lembar skor QEC; menentukan exposure score dengan metode QEC; penghitungan exposure level. Langkah tersebut dilakukan untuk setiap operator stasiun kerja. Maka diperoleh exposure level tertinggi pada operator stasiun kerja amplas mesin dengan presentase 62%, sehingga diperlukan penelitian lebih lanjut dan dilakukan Perubahan. Usulan rancangan perbaikan postur kerja yang disarankan untuk memperhatikan faktor risiko penting, seperti punggung tidak membungkuk, posisi tangan, kemudian frekuensi saat memutar tangan serta kekuatan tangan dan untuk bagian leher agar lebih rileks

Desain Mobile Unit Instalasi Pengolahan Air Minum untuk Kondisi Darurat Bencana Banjir Menggunakan Membran Ultrafiltrasi

Banjir merupakan bencana alam yang paling sering terjadi di Indonesia, yaitu terdapat 5.051 kejadian sejak tahun 1.815 hingga tahun 2013. Penyediaan air minum yang aman dapat menjadi sumber masalah kesehatan utama setelah bencana alam, namun menyediakan air minum untuk penduduk yang terkena bencana adalah aktivitas yang menantang karena kontaminasi yang parah dan kurangnya akses terhadap infrastruktur. Sebuah sistem pengolahan air minum onsite untuk penduduk yang terkena bencana adalah solusi yang lebih berkelanjutan daripada mengangkut air minum kemasan, sehingga pengolahan air minum mobile merupakan salah satu solusi yang tepat untuk kondisi banjir. Produksi air minum secara mobile cocok menggunakan membran karena sifatnya yang modular dan prosesnya sederhana. Dalam kaitan ini maka perlu direncanakan desain instalasi pengolahan air minum mobile untuk kondisi darurat bencana banjir dengan menggunakan membran. Membran yang digunakan adalah membran ultrafiltrasi. Membran ultrafiltrasi mempunyai kelebihan yaitu dapat menahan atau menyaring makromolekul (bakteri, ragi), namun tekanan yang dibutuhan rendah sehingga energi yang diperlukan rendah. Pada perencanaan ini juga direncanakan unit-unit pengolahan sebelum dan sesudah membran ultrafiltrasi sehingga kualitas effluent memenuhi baku mutu sesuai dengan PERMENKES RI No. 492/MEN.KES/PER/IV/2010
