Utilization of Striped Snakehead Fish and Tofu Dregs in Making Nugget

This research aimed to get the best formulation of striped snakehead fish and tofu dregs nuggets based on Indonesian National Standard SNI 7758-2013. A completely randomized design was conducted with five treatments, which were the ratios of striped snakehead fish and tofu dregs, such as 90:10, 85:15, 80:20, 75:25, and 70:30, and three replications. Data showed a significant effect of the ratio of striped snakehead fish and tofu dregs on moisture, ash, protein, crude fibre content, and descriptive analysis in sensory evaluation and overall hedonic test on nugget. The nugget from the ratio of striped snakehead fish and tofu dregs 90:10 was the best formulation with a moisture content of 64.66%, an ash content of 1.04%, protein content of 9.69%, a fat content of 0.65%, and crude fibre content of 0.61%. The descriptive sensory analysis showed that the nugget had a white color inside and a golden yellow outside, flavored with striped snakehead fish, a bit chewy, and had a striped snakehead fish taste

Pendugaan Umur Simpan Rendang Telur yang Dikemas Plastik High Density Polyetilen (HDPE) dan Aluminium Foil dengan Teknik Pengemasan Berbeda Menggunakan Metode Akselerasi

The purpose of this research is to estimate the shelf life of egg rendang  that is packed with High Density Polyetilen (HDPE) plastic, aluminium foil, and vacuum aluminium foil. Estimation of shelf life using the acceleration method by storing the egg rendang for 30 days at three different temperatures, i.e, 30°C, 35°C, and 40°C. The parameters observed during the storage process were sensory assessments of rancidity and thiobarbituric acid (TBA) values of egg rendang. Data were analyzed using linear regression and the equations obtained were used to calculate the shelf life of egg rendang at normal temperature, which is 27°C. The egg rendang stored using vacuum aluminium foil packaging have a longer shelf life compared to HDPE packaging and non vacuum aluminum foil. The egg rendang shelf life packed with aluminium foil vacuum based on rancidity sensory test was 100 days, with the regression equation y =-7241,9x+20,317, an activation energy (Ea) of 14.382,4 kal.mol-1, and the value of quality degradation (k) was 0.021 quality unit per day. The egg rendang shelf life packed with aluminium foil vacuum based on the TBA value was 99.50 days, with the regression equation y =-6995,3x+18,577, the activation energy (Ea) of 13.892.7 kal.mol-1, and the value of quality degradation (k) was 0.008 quality unit per day

Pembuatan Nugget Ikan Kembung Dengan Penambahan Jamur Tiram

The purpose of this study was to obtain the best ratio of oyster mushrooms in addition to the quality of mackerel fish nugget. The research method used a completely randomized design CRD experiment consisting of four treatments and four replications. The treatments consisted of KJ1 (ratio of mackerel fish and oyster mushrooms 70:30), KJ2 (ratio of mackerel fish and oyster mushrooms 60:40), KJ3 (ratio of mackerel fish and oyster mushrooms 50:50), and KJ4 (ratio of mackerel fish and oyster mushrooms 40:60). The data obtained were statistically analyzed using analysis of variance and continued with Duncan's multiple range test (DMRT) at the 5% level. The results showed that the ratio of mackerel fish and oyster mushrooms significantly affected moisture, ash, protein, and crude fiber content, as well as descriptive sensory assessments such as color before and after frying, aroma before and after frying, texture before frying, elasticity, taste and overall hedonic assessment. The best treatment was KJ3 (ratio of mackerel fish and oyster mushrooms 50:50) which of 56.45% moisture 1.11% ash, 15.40% protein, and 2.98% crude fiber content. The overall sensory assessment of the nugget was slightly white color before frying, yellowness after frying, a little oyster mushroom flavoring before and after frying, a little soft texture, chewy, and slightly oyster mushroom taste

Banana Hump Starch and Ginger Extract as Edible Coating to Extend the Shelf-life of Red Chili Peppers

Fresh red chili peppers is a product that spoils easily and has a concise shelf-life. Coating a natural edible coating on fresh red chili peppers will significantly increase their shelf-life. This research aims to obtain the best concentration of ginger extract in the edible coating of banana hump starch to extend the shelf-life of red chili peppers. The research was carried out experimentally using a completely randomized design with five treatments and three replications. The treatment in this research was an edible coating of banana hump starch with the addition of various concentrations of ginger extract; J0 (0%), J1 (1%), J2 (3%), J3 (5%), and J4 (7%); which were applied on red chili peppers for 15 days of storage. The parameters observed were weight loss, vitamin C, total microbes, and sensory assessment. The best treatment in this study was J4 (addition of 7% ginger extract). On the 15th day of storage, red chili peppers coated with edible coating treated with J4 experienced a reduction in weight loss of 41.20%, with 18.54 mg/100g of vitamin C and 5.89 log CFU/g of total microbes. Descriptive tests showed that on the 15th day of storage, red chili peppers had a red color, started to smell and taste rotten, and had a slightly hard texture
