Waktu Transit, Nilai Organoleptik, dan Nilai Keasaman (pH): Hasil Tangkapan Purse Seine

Abstract

ABSTRAK Penelitian ini bertujuan untuk mengetahui pengaruh antara fasilitas penanganan, cara penanganan, dan waktu transit dengan kualitas ikan pada alat tangkap purse seine. pengukuran pH dan nilai organoleptik lima jenis ikan yang dominan tertangkap di atas kapal, di Tempat Pelelangan Ikan (TPI) sebelum dilelang, dan di TPI sesaat setelah dilelang. Pengamatan juga dilakukan terhadap kondisi fasilitas dan cara penanganan di atas kapal dan di TPI dan durasi waktu sejak ikan ditangkap sampai selesai dilelang. Hubungan fasilitas penanganan, cara penanganan, dan waktu transit dengan kualitas ikan ditentukan menggunakan analisis uji t, regresi linear sederhana, dan regresi linear berganda. Lima Jenis ikan yang dominan tertangkap adalah cakalang (Katsuwonus pelamis), kembung lelaki (Rastrelliger kanagurta), kembung perempuan (Rastrelliger brachysoma), tembang (Sardinella), dan layang (Decapterus ruselli). Berdasarkan hasil analisis fasilitas penanganan di atas kapal dan di TPI, cara penanganan di TPI, dan waktu transit tidak berbeda (p>0,05). Hubungan nilai pH dengan organoleptik ikan diprediksi berdasarkan persamaan Y = 0,3978x + 2,7662; R2 = 0,9977, jika nilai organoleptik (X) = 0 maka nilai pH (Y) = 2,7662. Fasilitas penanganan di atas kapal (X1), cara penanganan di atas kapal (X3), dan waktu transit (X5) menentukan kualitas (organoleptik) sebesar 17,1% dengan persamaan regresi Y = 7,293-0,1461X1 + 0,0193 X3 + 0,1265X5 ;R2 = 0,171, sedangkan kualitas (pH) ditentukan hanya sebesar 4,4% oleh fasilitas penanganan di atas kapal (X1), cara penanganan di atas kapal (X3), dan waktu transit (X5) dengan persamaan Y = 5,697-0,0761 X1 + 0,1233X3 + 0,0125X5 ; R2 = 0,044, sedangkan 95,6% dipengaruhi variabel lain..

Observations were also made on the condition of the facility and how to handle it on board and at the TPI and the duration of time since the fish was caught until it was finished auctioned. The relationship between handling facilities, handling methods and transit times with fish quality was determined using t test analysis, simple linear regression, and multiple linear regression. Five dominant fish species were Katsuwonus pelamis, Rastrelliger kanagurta, Rastrelliger brachysoma, Sardinella, and Decapterus ruselli. Based on the results of the analysis of the aboard handling facilities and in the TPI, how to handle the TPI, and the transit time is not different (p> 0.05). The relationship of pH value with organoleptic fish was predicted based on the equation Y = 0.3978x + 2.7662; R2 = 0.9977, if the organoleptic value (X) = 0 then the pH value (Y) = 2.7662. Aboard handling facilities (X1), handling methods on board (X3), and transit time (X5) determine the quality (organoleptic) of 17.1% with the regression equation Y = 7.293-0.1461X1 + 0.0193 X3 + 0.1265X5, R2 = 0.171, while the quality (pH) was determined only at 4.4% by the above ship handling facility (X1), the method of handling on board (X3), and transit time (X5) with the equation Y = 5,697-0.0761 X1 + 0.1233X3 + 0.0125X5; R2 = 0.044, while 95.6% is influenced by other variables..
