Abstract

The effect of gain to The Width at Half Maximum (FWHM) and Full Width at Tenth Maximum (FWTM) on B-mode image ultrasonogram (USG) has been investigated. The aim of this research is to determine the effect of gain on the spatial resolution according the measurements of FWHM and FWTM. The evaluated resolution type is axial and lateral. This research used phantom multipurpose multi tissue with gain (30 dB, 35 dB, 40 dB, 45 dB, 50 dB, 55 dB and 60 dB) on frequency variation source 6,2 Mhz, 8 MHz dan 10MHz. The axial and lateral resolution images were obtained by using USG which uses B-Mode imaging. The measurement was made by using digital image and calculated objectively with MATLAB. The measurement of FWHM and FWTM was obtained from IP-PSF analysis (In Plane-Point Spread Function) using approximation for the Gaussian function. The result shows that there is influence from gain on FWHM and FWTM. The decreasing gain resulted in decreasing of FWHM and FWTM. The decreasing of FWHM and FWTM represents better spatial resolution, and vice versa. Keywords: FWHM, Gain, Point Spread Function, Spatial resolution, USG,

Abstract

Senyawa nitrat dan fosfat merupakan nutrien yang dapat dijadikan sebagai petunjuk kesuburan perairan dan dibutuhkan baik pertumbuhan dan perkembangan lamun. Nutrien di perairan padang lamun berperan sebagai faktor pembatas pertumbuhan. Penyerapan nutrien oleh lamun dilakukan oleh daun dan akar. Besarnya kandungan nutrien dalam sedimen bukan berarti akan selalu dalam konsentrasi yang sama pada karakteristik  sedimen dasar dan kedalaman perairan. Bila terjadi perbedaan maka hal ini bisa mempengaruhi terjadinya perbedaan kondisi kepadatan dan sebaran pada setiap jenis lamun yang tumbuh dalam perairan, oleh karena itu perlu dilakukan penelitian tentang hubungan kandungan Nitrat dan fosfat dalam substrat terhadap kerapatan lamun di perairan pantai Prawean, Jepara. Penelitian ini dilakukan pada bulan Desember 2018- Januari 2019. Metode penentuan lokasi pengambilan sampel dengan metode purposive sampling. Materi yang digunakan dalam penelitian adalah sampel sedimen, parameter perairan, dan kerapatan lamun. Berdasarkan hasil penelitian didapatkan Nilai kandungan Nitrat di substrat Perairan Pantai Prawean Jepara berkisar antara 1,27–1,36 mg/L tergolong pada kategori kesuburan rendah. Nilai kandungan Fosfat pada sedimen yaitu 0,049–0,086 mg/L tergolong pada kategori rendah hingga tinggi. Tingkat kerapatan padang lamun berada pada kondisi kerapatan sangat  rapat (> 175 tegakan/m2).  Nitrate and phosphate compounds are nutrients that could be used as an indicator of aquatic fertility and needed by for growth and development of seagrass. Nutrients in seagrass waters serve as a limiting factor for growth. Nutrient absorption by seagrass were done by leaves and roots. The amount of nutrient content in sediment does not mean would be always same at the concentration on the basic sediment characteristics and depth water level. If there is a difference, it will cause an affect the different conditions of density and distribution in each type of seagrass which grows in the waters, therefore it is necessary to do research about relation of nutrient in the substrate to seagrass density in Prawean Beach, Jepara. This research was conducted in December 2018 - January 2019. The method used in this study was descriptive method. The material used in the study were sediment samples, water parameters, and seagrass density.
