<em><span>Ventilators are one of the medical devices that are needed as a breathing apparatus for COVID-19 patients who have respiratory problems. One of the low-cost ventilators currently being developed by several domestic institutions is the ambu bag-based ventilator. The point is an air bag (bag) that is pressed by two carefully controlled automatic clamps, so that it can reach all, while taking into account portability, aesthetics and ease of manufacture. Therefore, the Bag Valve Mask (BVM) or ambu bag is an emergency option to replace the function of the ventilator. This study aims to make an ambu bag that can be applied as a portable mechanical ventilator. Thus, the ambu bag which was originally used manually can be used automatically like a ventilator machine in general. In determining the type of mechanical arm pressure, several parameters such as minute volume, respiratory rate, and tidal volume are used. As recommended by the American Heart Association (AHA) that the tolerance limit for the RR value is +/-10 BPM, it can be said that the automatic BVM as a result of this study can be used with or without a reservoir as needed or with the addition of oxygen</span></em>

<p>Air merupakan kebutuhan utama mahluk hidup. Kegunaan air yang bersifat universal atau menyeluruh dari setiap aspek kehidupan menjadi semakin berharga baik secara kuantitas maupun kualitas. Pengelolaan sumber daya air untuk penyelenggaraan irigasi berkaitan dengan keberlangsungan sistem irigasi dalam rangka pemenuhan kebutuhan pangan yang terus meningkat. Untuk menjaga keberlangsungan sistem irigasi memerlukan biaya operasional untuk terus menjalankan  pengelolaan sumber daya air irigasi untuk mendukung kegiatan pengelolaan irigasi. Di desa Mulyorejo terdapat pengelolaan jasa irigasi pompa yang mengambil sumber air bengawan solo yang terletak tepat di utara desa Mulyorejo. Di dalam rumah pompa tersebut terdapat 2 pompa sentrifugal dengan merk torishima pump yang berkapasitas besar, saat ini pengguna jasa irigasi pompa hanya areal persawahan masyarakat desa Mulyorejo, Hasil dari penelitian kali ini adalah kebutuhan air areal persawahan 65 Ha desa Mulyorejo sebesar 1.012 m³/h, kapasitas pompa 1.102 m³/h, dan jam operasional pompa dalam satu kali musim panen 1.152 jam. Dan jumlah biaya operasional dalam satu kali musim panen sebesar Rp. 147.043.420 Dengan besarnya kapasitas pompa dan banyaknya ketersediaan air, perlu pengembangan luas areal persawahan yang teraliri jasa irigasi pompa, dengan membuka komunikasi ke petani di samping kiri ataupun kanan desa, guna memanfaatkan kelebihan air dari kapasitas pompa.</p>
