Feasibility of Solid Waste Tuna Loin of Yellowfin Thunnus albacares Raw Materials for The Product Diversification

Abstract

<p>Indonesia is one country in the world exporters of tuna in the form of fresh, frozen and<br />processed. Tuna exported in processed form large enough to leave waste for exporting companies.<br />The purpose of this study was to determine a feasibility study on solid waste exported tuna loin for<br />raw material diversification. This research was conducted in Majene Makassar Strait. The study was<br />conducted using descriptive exploratory method by taking a sample of 3 times and each sample<br />was tested 3 times resulting in 9 times of testing for each of the observed variables. Chemical test<br />which includes moisture, protein, fat, ash, carbohydrates, and histamine. Microbiological test that<br />is E. coli, Salmonella and the total number of bacteria. Data were analyzed by descriptive qualitative<br />and quantitative display via Tables, Graphics and Image in the form of average value. The results<br />showed that the chemical solid waste tuna loin has a water content ranged from 78.34 to 78.78%,<br />protein content ranged from 14.32 to 16.41%, fat ranged from 1.56 to 1.66%, ash content ranged<br />from 5.18 to 5. 58%, carbohydrate content ranged from 1.29 to 1.34%, and histamine ranged from<br />2.08 to 3.21 mg / kg. Solid waste microbiologically tuna loin contains E.coli range from 1.2 to 1.9<br />(<2), Salmonella negative and TPC ranged from 1.4 to 1.8 x 105 kol/g. The results of chemical and<br />microbiological testing showed solid waste tuna loin still suitable as raw material diversification<br />products.</p>

Mortality, Development and Nutrient Content of Black Soldier Fly Larvae (Hermetia illucens L.) Maintained on Different Types of Household Organic Waste

“…Low fat content in BSF due to the high moisture content contained in larvae. Moisture content has the opposite relationship with the fat content that is the higher the moisture content contained then the lower the fat content [25]. The addition of animal protein waste in this study can increase protein levels.…”

Analisis mutu ikan kurisi dan swanggi hasil tangkapan nelayan di tempat pelelangan ikan Mayangan, Probollinggo

“…Sankar et al (2013) menyatakan kadar air ikan kurisi sebesar 75,72% dan Dileep et al (2011) menambahkan bahwa kadar air ikan swanggi sebesar 78,70% serta Jaziri et al (2022) menambahkan bahwa kadar air ikan swanggi sebesar 79,26%. Kantun et al (2015) menyebutkan bahwa salah satu hal yang membuat kadar air ikan tinggi disebabkan oleh lamanya waktu penangkapan dan kesalahan penataan ikan di dalam palka yaitu tidak adanya saluran pembuangan sisa darah, lendir, serta es. Lama waktu penangkapan kapal yang berlabuh di TPI Mayangan berkisar antara 3-5 hari serta keadaan palka pada saat kapal telah berlabuh terlihat banyak air, sisa darah, lendir dan juga es baik yang sudah mencair menjadi air maupun serpihan es, sehingga berpeluang merendam ikan dan meningkatkan kadar air dalam tubuh ikan tersebut.…”

Identifikasi Spesies Pendukung Perikanan Kembung dengan Alat Tangkap Purse Seine di Perairan Utara Probolinggo, Jawa Timur

“…Ikan ini dapat ditemukan pada zona neritik dan laut lepas dengan kedalaman sampai 90m dari permukaan perairan (Wandira, et al, 2019;Suwarso et al, 2015). Selain untuk dikonsumsi, ikan yang banyak ditemukan di perairan Natuna, Sumatra Barat, Laut Jawa, Selat Malaka, Laut Arafuru, dan Sulawesi Selatan (Utami et al, 2014) ini juga digunakan oleh nelayan pancing sebagai umpan untuk menangkap ikan seperti kakap merah, kakap putih, kerapu dan emperor (Kantun et al, 2014). Tingginya kebutuhan akan sumber daya ikan ini menyebabkan tekanan pada sumber daya ikan kembung cukup tinggi.…”
