Abstract

Combustion is a very complex matter. Therefore, we need to know the phenomenon that occur in combustion apart from the temperature distribution. This research uses quasi-research. The background in using quasi-experimental is because it has advantages in data collection. Moreover, the phenomena that occur in more detailed research by means of a numerical approach could also be observed. This research was conducted with an approach (simulation) of diffusion combustion using methane (CH4) fuel and air containing 29% oxygen (O2), 71% nitrogen (N2) and the addition of swirl in the air ducts. k-ɛ turbulence modeling was aaplied in this somulation. This variation of the fuel velocities are 3 m/s, 5 m/s, 7 m/s, where the air velocity was varied for 3 m/s, 5 m/s, 7m/s. In this simulation, room pressure of 1 atm was applied for the surrounding. The results showed that, the greater the angle of inclination of the swirl burner, the shorter the flame. And on the variation of fuel velocity, we get the result that the higher fuel velocity, increase fire height; however, the temperature of the fire height will decrease.

Abstract

ABSTRAK Bidan dalam memberikan pelayanan kebidanan yang paripurna dan berkesinambungan akan berorientasi pada asuhan kebidanan yang bersifat holistik. Hal itu tidak terlepas dari kompetensi yang harus dikuasai seorang bidan berdasarkan wewenangnya. Dalam praktiknya kompetensi bidan saat ini belum seperti yang diharapkan. Ilmu pengetahuan dan teknologi berkembang dengan pesat dan dampaknya terjadi perubahan nilai serta kebutuhan masyarakat yang meningkat terhadap bidan. Bila kondisi tersebut tidak diatasi, maka kepuasan dan kepercayaan masyarakat terhadap bidan akan semakin menurun. Penelitian bertujuan untuk mengetahui hubungan kompetensi asuhan kehamilan mahasiswa kebidanan dengan kepuasan pasien pada praktik klinik kebidanan. Metode yang digunakan adalah rancangan observasional analitik dengan pendekatan cross sectional. Populasi dalam penelitian ini adalah mahasiswa semester IV program studi DIII Kebidanan UNS dan pasien ibu hamil di rumah sakit dan puskesmas di wilayah Surakarta. Sampel dalam penelitian ini menggunakan total populasi. Analisis data menggunakan analisis bivariat Chi-Square dilanjutkan dengan regresi logistik. Simpulan penelitian adalah terdapat hubungan kompetensi asuhan kehamilan mahasiswa D III kebidanan dengan kepuasan pasien pada praktik klinik kebidanan.   Kata kunci: kompetensi, kepuasan pasien       ABSTRACT Midwives in providing maternity services that complete and continuous to be oriented holistic midwifery care. It was not separated from the competencies that must be controlled by a midwife pursuant to her authority. In practice competence of midwives currently not as expected. Science and technology is developing rapidly and the impact a change in the values and needs of the people who improve to the midwife.
