Fish is a rapidly decomposing source of animal protein, so good handling is important to ensure that the quality of the fish is preserved. How the freshness of fish meat can be preserved can be accomplished through the preservation process. By adding natural ingredients that can prevent the growth of bacteria using liquid smoke, one way of preserving fish meat can be achieved.However, in a traditional way, the application of producing liquid smoke is also carried out such that the resulting liquid smoke still contains ash, tar and carcinogenic compounds.In this reasearch, a pyrolyzer made from stainless steel 304 was designed, with a pyrolysis reactor with a capacity of 10 kg coconut shell and a multi-stage condensation system whose working principle utilizes the properties of smoke molecules that tend to flow or move from the bottom up, so that the higher the quality of the smoke molecules the better because they do not contain Ashes from combustion which cause the creation of carcinogenic Polycyclic Aromatic Hydrcarbon (PAH) compounds.The research method includes planning the pyrolyzer design, selecting engineering materials, procedures for making liquid smoke made from coconut shells, pyrolyzer performance test, testing the chemical content of liquid smoke. I. a) Should not contain Polycyclic Aromatic Hydrcarbon (PAH) more than 0.05 µg / kg of liquid smoke, PAH compounds can be carcinogenic, among the PAH Mustopa Kamal et al.
Tujuan penelitian ini adalah untuk mengetahui komoditi perikanan yang potensial atau unggulan dan menghitung potensi serta tingkat pemanfaatanya. Penelitian ini dilakukan dengan menggunakan metode survei dan observasi lapangan Pengumpulan data dilakukan dua tahap yaitu pengumpulan data primer di lapangan dengan pengamatan langsung dan data sekunder menggunakan kuesioner. Sumber data diperoleh berdasarkan informasi dari responden melalui wawancara dengan daftar pertanyaan atau kuesioner. Analisi data yang digunakan adalah menggunakan skoring dengan fungsi nilai sebagai standarisasi nilai untuk menentukan sumberya ikan unggulan dan surplus produksi dengan pendekatan Schaefer untuk menghitung kelimpahan dan tingkat pemanfaatannya. Hasil penelitian menunjukan bahwa sumberdaya ikan unggulan berdasarkan aspek nilai produksi; harga pasaran; wilayah pemasaran; dan nilai tambah komoditi dengan fungsi nilai ditetapkan komoditi kerapu menjadi unggulan teratas dengan nilai total 2,39. kelimpahan atau potensi lestari kerapu adalah 423 ton/tahun, effort yang optimum untuk memanfaatkan kerapu adalah 3.470 unit pancing, jumlah tangkapan yang diperbolehkan sebesar 339 ton/tahun, dan tingkat pemanfaatan mencapai 70% (Fully Exploited) artinya upaya penangkapan dipertahankan dengan monitor ketat.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
