Abstract

Asap cair dari kayu karet dapat digunakan sebagai bahan pengawet ikan kembung (Rastrelliger kanagurta) karena mengandung senyawa fenol dan asam organik yang bersifat sebagai senyawa anti bakteri dan antioksidan. Penelitian ini bertujuan untuk menentukan konsentrasi asap cair kayu karet redestilasi dan lama perendaman ikan terbaik pada pengasapan ikan kembung. Penelitian menggunakan rancangan acak kelompok faktorial (RAK Faktorial) dengan perlakuan konesntrasi asap cair (10, 15 dan 20%) dan lama perendaman (10, 15 dan 20 menit). Analisis yang dilakukan meliputi angka lempeng total, kadar air dan organoleptik. Hasil terbaik yaitu menggunakan konsentrasi asap cair kayu karet redestilasi 10% dan lama perendaman ikan selama 15 menit dengan nilai angka lempeng total 4,4×103 CFU/g pada hari ke-0 dan 4,7×104 CFU/g pada hari ke-6, kadar air di bawah 60% selama penyimpanan, dan sifat organoleptik berupa skor aroma 4,48 (netral)dan skor penerimaan keseluruhan 4,51 (netral).

Abstract

Cellulose from the solid waste of seaweed Eucheuma cottonii is one of the wastes that can be used as raw material for making biodegradable films. The condition for making optimum conditions for making biodegradable film from E. cottonii with treatment of glycerol concentration (0; 0,25; 0,5; 0,75; and 1%), tapioca concentration (2; 4; 6; 8; and 10%) , carboxy methyl cellulose (CMC) concentration (1; 2; 3; 4and 5%) and chitosan concentration (1; 2; 3; 4; and 5 The experimental design uses a surface response method with 4 replications. The analysis carried out consisted of elongation percent, tensile strength, solubility and biodegradable film using surface response method. The optimum value occurs in the process conditions using a concentration of glycerol of 0.162%, tapioca concentration of 3.78%, CMC concentration of 2.5% and chitosan concentration of 1.62% with tensile strength 95.013 Mpa, percent elongation of 8.92%, and solubility 80.62%.

Abstract

Used newsprint is one of the most potential materials to be recovered into pulp raw material. The problem is the color of newsprint that requires bleaching process. One of the oxidizing agents used for bleaching is the peroxide acid in the acetic acid medium. The purpose of this research is to know the effect of peroxide acid concentration in acetic acid media and the duration of heating to the chemical properties of pulp produced. The best results were obtained at 12% per oxide acid concentration in acetic acid medium and 5 hour heating time, yielding 58.653% cellulose, hemicellulose 9,033%, lignin 22,683%, and color score 4,503% (rather white).

Abstract

Fish proccessed product is a favorite food that contain high protein in Indonesia, such as, otak-otak ikan. The aim of this research was to observe of phatogen bacteria contaminant on fish proccessed product, ex. Salmonella sp., Escherichia coli and Staphylococcus aureus. This research was had done on food proccessed product, used random sampling technicque, at traditional markets. The result data was arranged with descriptive statistic. The result research showed that contaminant of Escherichia coli was 1.54 x 102 colony/ ml at Tani market; 0.3 x 101 colony/ml at Gudang Lelang market. Fish proccessed product was contaminated by Salmonella, too. This research found that Fish proccessed product at Tamin, Tani and Rajabas was Salmonella contaminant detected. The Fish proccessed product that content the highest level of Stahpylococcus aureus were at Tugu narket (1,07 x 102 colony/ml) and Gudang Lelang market (1,12 x 102 colony/ml).
