Abstract

Penelitian ini bertujuan untuk menentukan pengaruh penggunaan ekstrak etanolik Padina sp. terhadap daya simpan filet ikan kembung selama penyimpanan pada suhu kamar. Filet ikan kembung direndam selama 30 menit dalam larutan ekstrak etanolik Padina sp. dengan konsentrasi 0; 0,5; 1; 1,5; dan 2 g/ 100 mL akuades. Filet ikan kembung kemudian disimpan pada kotak styrofoam pada suhu kamar selama 24 jam dengan selang waktu pengamatan setiap 6 jam. Parameter yang diamati meliputi: pH, Total Plate Count (TPC), kadar histamin, kandungan bakteri pembentuk histamin (BPH), dan organoleptik (kenampakan, bau, dan tekstur). Hasil penelitian menunjukkan bahwa penggunaan ekstrak etanolik Padina sp. yang berbeda memberikan pengaruh nyata (p<0,05) terhadap nilai TPC, kandungan BPH, dan nilai organoleptik keseluruhan filet ikan kembung selama 24 jam. Filet ikan kembung yang diberi ekstrak etanolik Padina sp. masih layak konsumsi hingga jam ke-6.

Abstract

Indonesia as one of the developing countries has a high dependence on petroleum fuels derived from petroleum refinery as the main energy source. the use of foil in Indonesia is dominated to meet the needs of transportation vehicles. Fuel oil as a source of energy into the spotlight in the world lately because of the impact of environmental degradation that arise from the utilization. The industrial activity of fuel oil production in refineries is inseparable from the environmental impacts. The oil processing process at the refinery is the second highest emission contributor after the use of fuel oil itself during its product life cycle. In this research LCA analysis is conducted for the production of gasoline (bensin) and gasoil (diesel) vehicle fuels during processing at the refinery to compare the environmental impact of each type of fuel. From the result of LCA analysis, it is known that from two types of vehicle fuel, to produce 1 kilo litter of gasoline (bensin) type more energy and produce higher emission compared to diesel type gas (gasoil) fuel production. The gasoline fuel produced in the platformer unit is the product that has the highest emission contribution in its production process with greenhouse gas emissions of 1 Ton CO-2eq and the acid gas emissions of 0.001 Ton SO-2eq per 1 kilo litter of the resulting product.
