As a representative of the Minang Region, the city of Padang is very representative of sampling chicken rendang because each rendang has a different process and taste. This research examined the quality, nutritional value, and taste of chicken rendang sold in Padang City. The method used in this research was a survey method with random sampling (purposive sampling), and then laboratory analysis was carried out. Data processing used a 9x2 randomized block design (nine samples and two groups), with samples being places where chicken rendang was taken from 8 restaurants in the city of Padang and one chicken rendang sold commercially (packing) as a control, while quality test without using controls. The parameters observed were quality (FFA, TBA, and cholesterol levels), nutritional value (moisture content, protein content, fat content, ash content), and sensory analysis (color, aroma, texture, and taste of 30 untrained panelists) of chicken rendang. Sample G had the highest nutritional value but was lower than the sensory analysis. On the other hand, the sample I had the highest sensory assessment and high-fat content. Sample D was the best sample regarding quality, nutritional value, and sensory with FFA 0.800%, TBA 0.021 mg malonaldehyde/kg, cholesterol levels 44.35 mg/dl), nutritional value (moisture content 45.03%, protein content 14.48%, fat content 15.44%, ash content 2.80%), and sensory analysis neutral.</p> Deni Novia Yuherman Winda Sartika Rini Rustini Copyright (c) 2024 Deni Novia, Yuherman, Winda Sartika, Rini Rustini https://creativecommons.org/licenses/by-nc-sa/4.0 2024-03-30 2024-03-30 19 1 1 14 10.21776/ub.jitek.2024.019.01.1 Enhancement of Antibacterial Activity from Chicken Head Protein Hydrolysate Using Dual-Enzyme Hydrolysis https://www.jitek.ub.ac.id/index.php/jitek/article/view/738 <p>The chicken head is one of the by-products with a high protein content. Therefore, chicken heads can be used as raw materials to produce protein hydrolysates containing bioactive peptides that have biological activities, such as antibacterial, anti-inflammatory, and antioxidant activities. This research aimed to evaluate the use of the combined ratio of papain and bromelain enzymes to produce chicken head protein hydrolysate that has antibacterial activity. The research method used in this study was a laboratory experiment using a completely randomized design (CRD) with four treatments and five replications. Statistical significance was done using one-way analysis of variance (ANOVA) followed by Duncan’s multiple range test (DMRT). The inhibition zones of chicken head protein hydrolysate using a combination of papain enzymes against <em>Lactobacillus casei</em>, <em>Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, </em>and <em>Salmonella typhimurium</em> were 1.72-2.68, 1.19-4.47, 0.93-1.45, 1.64-2.46, and 1.01-3.62 mm, respectively. The result showed that the highest antibacterial activities against <em>Lactobacillus</em> <em>casei</em>, <em>Escherichia</em> <em>coli, </em>and <em>Staphylococcus aureus</em> were in A1 (hydrolysis using papain 75% and bromelain 25%), the highest antibacterial activities against <em>Pseudomonas aeruginosa</em> was in A3 (hydrolysis using papain 25% and bromelain 75%), and the highest antibacterial activity against <em>Salmonella typhimurium </em>was in A2 (hydrolysis using papain 50% and bromelain 50%). However, all the hydrolysate didn’t exhibit antibacterial activity against<em> Bacillus subtilis</em>. Chicken head protein hydrolysate had the potential to be an antibacterial agent against pathogenic bacteria.</p> Pramudya Andiana Moch.

The research method used experimental method, counting was a completely randomized design consisting of 5 treatments and 4 replications. As a treatment, the storage time for purebred chicken egg flour at room temperature is formulated as follows T<sub>0</sub> (0 days), T<sub>1</sub> (10 days), T<sub>2</sub> (20 days), T<sub>3</sub> (30 days) and T<sub>4</sub> (40 days). The variables observed were water content, pH and total microbes. The results of analysis of variance showed that storage time at room temperature had a highly significant different effect (P&lt;0.01) on the water content, pH and total microbes of purebred chicken egg flour. The results of the orthogonal polynomial test show that storage time at room temperature has a highly different linear effect on water content obtained by the equation Y=6.561+0.0177X, linear and quadratic on pH obtained by the equation Y=7.64+0.0095X+0.00015X<sup>2</sup> and total microbial colonies of purebred chicken egg flour obtained by the equation Y=2686-0.0172X+0.0006X<sup>2</sup>. It can be concluded that the kinetics of deterioration in the quality of purebred chicken egg flour occurs 0.25% increase for water content and 0.25 increase for pH and 0.24 log cfu/g increase in the number of bacterial colonies during storage.</p> Merri Diana Rotinsulu Sjaloom Ester Sakul Copyright (c) 2024 Merri Diana Rotinsulu, Sjaloom Ester Sakul https://creativecommons.org/licenses/by-nc-sa/4.0 2024-03-30 2024-03-30 19 1 25 32 10.21776/ub.jitek.2024.019.01.3 Effect of Temperature and Duration of Gasbio Heat Energy on Bee Pollen Bioactive Compounds and Bee Propolis Extraction Trigona sp https://www.jitek.ub.ac.id/index.php/jitek/article/view/748 <p>Processing of dried bee pollen and propolis extraction to optimize the use of processed by-products of <em>Trigona sp</em> bees in the general public by utilizing biogas as heat energy. This research uses bee pollen and raw bee propolis (<em>Trigona sp)</em>.

Laboratory test results showed pH levels of 3.4, moisture content of 18.2 %, reducing sugar levels of 55.44 % and 56.71 % and diastase enzyme activity of 3.18 DN and 3.19 DN. In conclusion that formula feeding did not show high honey production when compared to the time taken to reach harvest and also did not show fulfilling reducing sugar content and diastase enzyme activity test results.</p> Aulia Fahnaz Fanisa Dedi Fardiaz Dewi Masyithoh Copyright (c) 2024 Aulia Fahnaz Fanisa, Dedi Fardiaz, Dewi Masyithoh https://creativecommons.org/licenses/by-nc-sa/4.0 2024-03-30 2024-03-30 19 1 54 62 10.21776/ub.jitek.2024.019.01.6 Effect of Chitosan-Beeswax Edible Coating on Microbiological Profile of Chicken Thigh Meat at Freezer Storage https://www.jitek.ub.ac.id/index.php/jitek/article/view/744 <p>This research examined the effect of chitosan and beeswax edible coating with different percentages on the microbiological value (aerobic bacteria, <em>Staphylococcus aureus</em>,<em> Coliform,</em> and <em>Escherichia coli</em>) of chicken thigh meat in two days of storage at freezer temperature (-18<sup>o</sup>C to -20<sup>o</sup>C). The study used Completely Randomized Design with 4 treatments and 5 replications. Treatments included were A0 (control), A1 (chitosan 2%), A2 (chitosan 2% + beeswax 1%), and A3 (chitosan 2% + beeswax 2%). Variables observed were the number of aerobic bacteria, <em>S. aureus</em>, <em>Coliform</em>, and <em>E. coli</em> using 3M<sup>TM</sup> Petrifilm<sup>TM</sup> Plates. Results showed significant differences (p&lt;0.05) in the number of aerobic bacteria colonies with the least colony on treatment A1. <em>S. aureus</em> and <em>Coliform</em> colonies showed significant differences (p&lt;0.05) with the least colony on treatment A2 and A3, sequentially. There was no significant difference (p&gt;0.05) in <em>E. coli</em> count due to no colonies detected on all treated samples. However, compared to controlled samples, it was found to decrease. The decrease in colony numbers shows that edible coating treatments can be used to help preserve or extend the shelf life of chicken thigh meat.</p> Salwa Haneefah Fauzia Dedi Fardiaz Laprianika Retha Hapita Sari Dewi Masyithoh Copyright (c) 2024 Salwa Haneefah Fauzia, Dedi Fardiaz, Laprianika Retha Hapita Sari, Dewi Masyithoh https://creativecommons.org/licenses/by-nc-sa/4.0 2024-03-30 2024-03-30 19 1 63 68 10.21776/ub.jitek.2024.019.01.7
