Abstract

This study was conducted to find out how the effect of different fish bone meal substitution ingredients on the hedonic test properties of crackers. This study uses an experiment method  with 2 factors, namely fish bone type factors (tuna fish bones and starry triggerfish bones), fish bone meal comparison factors (10%, 15% and 20%). The hedonic test (preference test) is used to measure organoleptic properties (taste, aroma, color, and texture). Nonparametric data were analyzed using the Kruskall-Wallis method  and continued  with the Mann-Whitney test  if there were significant differences and the Bayes test was carried out  to determine the best treatment. Based on the results of the study, it can be concluded that panelists still like crackers added with tuna and starry triggerfish bone meal in all treatments. However, treatment B which added  starry triggerfish bone meal by 10% resulted in crackers that were preferred over other treatments. The taste preference values for taste, aroma, color, and texture were 8.36±0.15, 8.23±0.10, 8.18±0.05, and 8.19±0.05 respectively.

Abstract

Limbah secara luas diklasifikasikan menjadi dua kategori sebagai biodegradable dan non biodegradable. Salah satu limbah yang saat ini menjadi masalah lingkungan adalah limbah yang berasal dari ikan. Limbah jika tidak dimanfaatkan pada akhirnya akan mencemari lingkungan. Proses pengomposan merupakan salah satu kegiatan untuk mengubah limbah menjadi produk yang bermanfaat. Penelitian ini bertujuan mengetahui apakah limbah ikan dapat dijadikan pupuk organik dengan penambahan sumber mineral yang berbeda dan untuk mengetahui sumber mineral manakah yang terbaik dalam pembuatan pupuk organik kompos. Penelitian ini dilakukan di Lampoh Keude, Aceh Besar, serta pengujian pH, N,P,K dan C-Organik yang  dilakukan di Laboratorium Ilmu Tanah dan Tanaman Fakultas Pertanian Universitas Syiah Kuala. Parameter pengujian pada penelitian ini adalah pH, N,P,K dan C-Organik dan uji organoleptik spesifikasi aroma. Hasil penelitian menunjukkan bahwa limbah ikan dapat dijadikan pupuk organik dengan penambahan sumber mineral yang berbeda karena mengandung Unsur N, P, K C-organik dan pH yang sesuai standar kualitas pupuk organik (SNI 19-7030-2004). Sumber mineral yang terbaik dalam pembuatan pupuk organik kompos dalam penelitian ini berdasarkan uji organoleptik adalah limbah sayuran karena memiliki tingkat kematangan dengan rasio C/N paling rendah yaitu 12 %, dan berdasarkan uji laboratorium adalah limbah buah karena mengandung kandungan unsur C- organik (18,68%) dan unsur N (1,55%) yang lebih tinggi dari yang lain, selain itu juga mengandung unsur P dan K yang masih tergolong tinggi serta nilai pH yang normal juga mengandung rasio C/N kedua lebih rendah daripada lainnya.

Abstract

This study was conducted to determine the effect of oyster shell flour additives on the properties of the cracker organoleptic test. The research method used is the Laboratory experimental method through two stages of making oyster shell flour with NaOH 0.1 N and husk ash, and making crackers with the addition of oyster shell flour is selected as the best of the two flours as ingredients in making crackers. Nonparametric data were analyzed using the Kruskall-Wallis method, the Mann-Whitney test if there was a significant difference, followed by the Bayes test to determine the best treatment. Oyster shell crackers were selected by 30 semi-trained panelists, and the results showed that treatment D (addition of 15% oyster shell flour) resulted in more preferred crackers than other samples, with a taste value of 7.86±0.02, aroma value of 7.71±0.07, texture 7.75±0.07 (crispy), and color 7.79±0.02 (faded yellow, similar to the color of crackers in general).

Abstract

The aim of this research is to determine the effectiveness of traditional drying methods on several types of fish. Comparing the quality of dried fish products from drying with the SNI requirements for dried fish, looking for methods that are suitable for types of fish in traditional drying. Optimal time to produce the best quality fish. The research results showed that drying this type of fish was different from drying it under direct sunlight for 8 hours per day for 3 days. The average value of percent water content obtained ranged from 26% -32%. It was concluded that drying using traditional methods could be the right choice for drying fish.

Abstract

There are several compounds in flavoring that give food's special aroma, taste or characteristics, such as Monosodium Glutamate (MSG). MSG is a synthetic chemical that if consumed in excess can have a bad impact on health. MSG can be replaced with natural flavors that have a similar taste. Fish skin and bones have a high content of calcium and phosphorus, in addition to minerals, proteins and volatile compounds, so they can be used as natural spices as consumer awareness of natural flavors increases. This study aims to determine the effect of the comparison of tuna fish bone and skin (Thunnus sp.) as a natural flavor on organoleptics. The research method used is an experimental laboratory method, this study used two different types of waste and each treatment was carried out 3 times, The type of waste used was tuna bones and skin. With a ratio of water and tuna bone and skin waste, namely: 1:2 (b/v), 1:3 (b/v), 1:4 (w/v). Nonparametric data were analyzed using the Kruskall-Wallis method, the Mann-Whitney test if there was a significant difference, followed by the Bayes test to determine the best treatment. Flavoring was analyzed by 30 trained and semi-trained panelists. Based on the results of the organoleptic test, the best flavor was found in sample E with a taste preference value of 6.82±0.068, aroma 6.89±0.11, color 7.19±0.02, and texture 7.14±0.08.
