Abstract

Status kesehatan ternak dalam suatu lingkungan merupakan hal penting yang mendukung keberlangsungan budidayanya yang dapat dilihat melalui parameter profil hematologis. Penelitian ini bertujuan untuk mengetahui profil hematologis sapi pasundan betina dipelihara di Kandang Teaching Farm Ciparanje. Penentuan sampel dilakukan meggunakan teknik purposive sampling. Objek penelitian adalah sapi pasundan betina terdiri dari rentang umur 1,5 – 2 tahun sebanyak 9 ekor dan umur >2 tahun sebanyak 9 ekor. Parameter yang diukur adalah jumlah leukosit, jumlah eritrosit, kadar hemoglobin, nilai hematokrit, dan indeks eritrosit. Hasil penelitian menunjukkan sapi pasundan kelompok umur 1,5-2 tahun memiliki jumlah leukosit, jumlah eritrosit relatif lebih tinggi dan kadar hemoglobin, nilai hematokrit, dan indeks eritrosit relatif lebih rendah dibandingkan kelompok umur >2 tahun. Kisaran profil hematologis penelitian ini dapat berguna sebagai nilai referensi untuk pemeliharaan sapi pasundan dalam mengevaluasi kondisi klinis yang berbeda.

Abstract

Research was carried out on the analysis of the sound absorption level of several types of patchwork acoustic materials which aims to find out whether patchwork can be used as a sound dampening material, to determine the sound absorption level of several types of patchwork acoustic materials and to determine the best attenuation level of several types of patchwork acoustic materials. the type of patchwork acoustic material. The background of this research is due to the acoustic quality of the room which has received less attention for the comfort of listeners when they are in a room. The study used variations of sound absorbing materials, namely cotton and denim patchwork. Measurement of the sound absorption coefficient of patchwork is done by making a sample chamber with a length of 13.5 cm, a width of 13.5 cm and a height of 8.5 cm. Sound Level Meter is a tool used to measure the level of sound pressure. Variations in the thickness of the patchwork used were 3, 5, and 10 mm. In measuring the entire inner wall surface of the sample room will be covered with patchwork, then the speaker is placed in the sample room. The sound source comes from speakers with a frequency of 90 dB which is arranged in a frequency range of 125, 250, 500, 1000, 2000 and 4000 Hz. The best damping level of the three materials is a mixture of cotton and denim with a thickness of 10 mm, because the thicker the patchwork layer, the α value obtained is 0.629.
