Abstract

The process of curing fish is generally done by using wood burning smoke. The utilization of wood is not efficient and lead to negative effect to the environment. Therefore it is necessary to modify the smoked fish meat processing by utilize a liquid smoke. The aim of this study was to determine the optimum combination of palm oil shell liquid smoke concentration and immersion time in smoke catfish meat production. The result showed that the optimum condition was obtained from the treatment of 2% (v/v) palm oil shell liquid smoke concentration and 30 minutes of immersion time with water content of 59,80%, fat content 23,73%, protein content 28,99%, and TPC 6.42x104 cfu / gram. Organoleptic analysis was performed to find out the panelist's preference of color, flavor, and texture with values of 3.57%, 3.93%, and 3.64%. The feasibility study was shown that the smoke catfish meat production by using palm oil shell liquid smoke is feasible to conduct. Proses pengasapan ikan pada umumnya dilakukan dengan menggunakan asap hasil pembakaran kayu. Penggunaan kayu tidak cukup efisien dan memiliki nilai negatif dari segi pengelolaan lingkungan. Oleh karena itu perlu dilakukan dimodifikasi proses pembuatan daging ikan asap dengan menggunakan asap cair. Penelitian ini bertujuan untuk mendapatkan konsentrasi dan lama perendaman daging ikan patin yang optimum didalam asap cair dari cangkang kelapa sawit yang tepat untuk daging ikan patin asap. Hasil yang diperoleh menunjukkan bahwa kondisi optimum didapat dari perlakuan konsentrasi asap cair 2% (v/v) dan lama perendaman 30 menit. Dengan kadar air 59,80%, kadar lemak 23,73%, kadar protein 28,99%, dan TPC 6.42x102 cfu/gram. Uji organoleptik terhadap warna, rasa, dan tekstur dengan nilai 3,57%, 3,93%, dan 3,64%. Analisa kelayakan usaha menunjukkan bahwa proses pembuatan ikan patin asap dengan menggunakan asap cair dari cangkang kelapa sawit layak untuk diusahakan.

Abstract

This study aims to determine the best dosage of Nitrogen fertilizer and biochar on mustard plant pakcoy (Brassica rapa L.) in inceptisol soil. The research was conducted in Hamlet Kraguman, Tegalwaru Village, Dau District, Malang Regency, East Java Province, for three months from September to November 2016. The study used Randomized Block Design (RAK) with 13 treatments and repeated 3 times. Observation was done 3 times that is age 25 HST, 35 HST, 45 HST with observed variables include plant height, leaf area, number of leaves, wet weight, and dry weight of mustard plant pakcoy. The results showed that the interaction of nitrogen and biochar fertilizers did not affect all observation parameters. Provision of nitrogen and biochar fertilizers increases the percentage of plant height increase, leaf area, wet weight, and dry weight of mustard plant pakcoy. Penelitian ini bertujuan untuk menentukan takaran pupuk nitrogen dan biochar terbaik pada tanaman sawi pakcoy (Brassica rapa L.) di tanah inceptisol. Penelitian dilaksanakan di Dukuh Kraguman, Desa Tegalwaru, Kecamatan Dau, Kabupaten Malang, Provinsi Jawa Timur, selama tiga bulan mulai September ? November 2016. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan 13 perlakuan dan diulang sebanyak 3 kali. Pengamatan dilakukan sebanyak 3 kali yaitu umur 25 HST, 35 HST, 45 HST dengan variabel yang diamati meliputi tinggi tanaman, luas daun, jumlah daun, bobot basah, dan bobot kering tanaman sawi pakcoy. Hasil penelitian menunjukkan bahwa penggunaan pupuk nitrogen dan biochar tidak berpengaruh terhadap semua parameter pengamatan. Pemberian pupuk nitrogen dan biochar meningkatkan persentase pertumbuhan tinggi, luas daun, bobot basah, dan bobot kering tanaman sawi pakcoy.
