Abstract

It has been tested against carrageenan characteristics resulting from harvesting seaweed with different ages, namely 30 days, 45 days, and 60 days. The purpose of this study was to determine the exact age of harvest in relation to the characteristics carrageenan produced from seaweed Kappaphycus alvarezii in coastal waters Desa Tolongio, Kec. Anggrek Kab. Gorontalo Utara. The research was carried out for 6 months from preparation to reporting. The method used was the explorative method, by using a Completely Randomized Design (CRD) with three replications. To determine the effect of harvest age on the characteristics carrageenan, we had tested the gel strength, viscosity, whiteness, water content, ash content and heavy metal (Hg). And to see differences between the treatment and to determine the best harvest age followed by Least Small Difference Test (LSD). All observational datas were tabulated and processed statistically using SPSS 16.0. Based on the results of research, it was known that carrageenan that was harvested of 45 days had some characteristics that approach required carrageenan for trading, namely 318.07 g/cm2 gel strength, viscosity of 101.33 cP, 10.72% ash content, and heavy metal (Hg) was not detected, whereas the water content of 23.68% and 37.2% whiteness degree was still not meet the standards of commercial carrageenan.

Abstract

Penelitian tentang analisis organoleptik dengan metode uji pembedaan (discriminative test) ikan teri (Stolephorus sp.) kering dari lama pengeringan berbeda dengan ikan teri komersial dari Desa Tolotio, Kecamatan Bonepantai, Kabupaten Bone Bolango, Provinsi Gorontalo telah dilaksanakan pada bulan Oktober sampai Desember 2013. Tujuan penelitian adalah untuk mengetahui perbedaan ikan teri kering hasil penelitian dengan ikan teri komersial. Penelitian menggunakan uji hipotesis berekor dua, dengan jumlah panelis yang dipakai 25 orang semi terlatih. Perlakuan penelitian yaitu lama pengeringan yang terdiri atas 24 jam, 28 jam, dan 32 jam. Parameter yang diamati pada penelitian ini adalah pembedaan secara organoleptik yang terdiri atas tekstur, aroma dan warna. Data hasil uji pembedaan dibandingkan dengan Tabel Hipotesis Berekor Dua pada taraf kepercayaan 5% dan 1%. Hasil analisis menunjukan bahwa ikan teri hasil penelitian pada semua perlakuan dapat dibedakan secara sangat nyata dengan ikan teri komersial berdasarkan atribut tekstur dan warna, namun berbeda nyata berdasarkan atribut aroma yaitu pada lama pengeringan 28 jam. Tekstur ikan teri kering hasil perlakuan lebih keras serta mudah dipatahkan dan warna dari ikan teri kering lebih cerah dibandingkan dengan ikan teri komersial. Aroma ikan teri hasil perlakuan yang berbeda tersebut memiliki aroma ikan teri yang lebih kuat dibandingkan dengan dua pelakuan yang lain dan ikan teri komersial. Kata kunci: Ikan teri, Stolephorus sp., pengeringan, uji pembedaan

Abstract

This study aims to determine the characteristics of the formula selected and crackers made from corn starch with the addition of tilapia (Oreochromis niloticus). Treatment factors in this study were different concentrations of tilapia were 30%, 50% and 70%. At the formulation stage conducted organoleptic tests (hedonic) against crackers consisting of texture, taste, color, appearance, and aroma. Phase characterization analyzed are the organoleptic quality of hedonic include texture, flavor, appearance and aroma. Hedonic test results indicate that the selected product is a composition of formula B with 100% corn starch and 50% of tilapia. Kruskal Wallis test results showed that the addition of tilapia no significant effect on the texture and flavor, but significant effect (p
