Abstract

The caffeine, antioxidant levels, and the quality of coffee powder produced by some small and medium industries in Tanah Datar District were determined in this study. The results of this study are expected to be a reference for the public regarding the caffeine and antioxidants content, as well as the quality of the coffee powder. Samples were obtained from 3 sub-districts in Tanah Datar District, including Salimpauang District, Sungai Tarab District, and Limo Kaum District. The purposive sampling method was used in this study by considering the most famous coffee powder products and well-liked by the public. Analysis of the characteristics of the coffee powder included the caffeine and antioxidant levels, water content, and ash content, as well as organoleptic tests. The results showed that the caffeine content of the coffee powder of most SMI (4 from 6 SMI sample) in the Tanah Datar Regency met the quality standards of SNI.  The content of antioxidant was ranged from 32,79 to 39,53%. Likewise, the water (7%)  and ash (5%) content have fulfilled the SNI 01-3542-2004 quality standards.

Abstract

Pempek merupakan salah satu jenis makanan tradisional masyarakat Sumatera Selatan dengan bahan utama daging ikan dan tepung tapioka serta ditambahkan air dan garam. Penelitian ini bertujuan untuk mempelajari pengaruh penambahan bahan lokal tepung talas Bogor dan penggunaan ikan lele dumbo terhadap profil tekstur dan kesukaan pempek lenjer serta kadar protein dan seratnya. Metode penelitian yang digunakan meliputi proses pemfilletan daging ikan lele, pembuatan adonan dengan campuran tepung tapioka dan talas, pembentukan pempek lenjer, dan perebusan. Perlakuan yang digunakan adalah perbandingan tepung tapioka dan tepung talas Bogor sebesar 100g:0g, 85g:15g, dan 70g:30g serta penggunaan daging ikan lele dumbo sebanyak 90g, 100g, dan 110g. Pempek yang telah dihasilkan kemudian diuji profil tekstur yang meliputi kekerasan, kekenyalan, dan kelengketan serta uji hedonik yang meliputi warna, aroma, rasa, dan tekstur kekenyalan. Hasil menunjukkan bahwa penggunaan ikan lele dumbo dan tepung talas Bogor yang lebih banyak menyebabkan kecenderungan semakin menurunnya tingkat kekerasan dan meningkatnya tingkat kekenyalan pempek lenjer yang dihasilkan serta tidak berpengaruh secara nyata terhadap tingkat kelengketan. Uji hedonik menunjukkan bahwa penambahan tepung talas dan ikan lele cenderung memiliki nilai kesukaan yang masih rendah terhadap parameter aroma, rasa, dan tekstur kekenyalan walaupun nilai kesukaan terhadap parameter warna cenderung memiliki nilai kesukaan yang lebih tinggi. Selain itu, uji hedonik menghasilkan kombinasi perlakuan perbandingan tepung tapioka dan talas 85g:15g dan ikan lele sebanyak 100 g sebagai perlakuan terpilih dalam penelitian ini. Pempek terpilih memiliki kadar protein dan serat pangan sebesar, berturut-turut, 7,06% dan 2,16%.

Abstract

The development of taro flour as raw material for instant porridge requires the addition of other constituents to improve the quality of sensory and nutrition. The research aimed to determine the effect of the addition of pumpkin flour to the level of preference and content of oxalic acid and calcium oxalate instant taro-skipjack fish. The study used a Completely Randomized Design with the treatment of 3 concentrations of pumpkin flour (5%, 10%, 15%) applied to taro-skipjack fish-taro flour as an instant porridge material. The results showed that the level of panelists' preference increased with increasing concentrations of pumpkin flour. The treatment of pumpkin flour 15% produced the best sensory instant pulp both in terms of color, taste, aroma, and texture. The content of oxalic acid and calcium oxalate in the treatment was 0.54 mg / 100 g and 2.41 mg / 100 g, respectively.

Abstract

Propolis is one of the natural products from Trigona sp. containing flavonoid compounds which have antimicrobial, antifungal, and antioxidant activity.  The purpose of this research was to determine the ethanol concentration, extraction methods, and characteristics of propolis extract that can inhibit the growth of Escherichia coli bacteria.  The method used was a randomized block design with 6 treatments in 3 replications. The treatments consisted of extraction methods and ethanol concentrations of 50%, 70%, and 90%.  The best results of this study were the extraction of propolis by the maceration method at 70% ethanol concentration. This propolis extract had a value of antimicrobial activity against Escherichia coli of 4.65 mm, brownish-black color, typical aroma of strong propolis, bitter taste, and had a minimum effective value of growing bacteria of 0.20% extract.

Abstract

The quality of ice cream is largely determined by the type of emulsifier used.  The utilization of an appropriate emulsifier will produce ice cream with good quality. A mixture of Mono-Diacylglycerol made from fully Hydrogenated Palm Kernel Oil (furthermore in this paper we named it as MDAG) and Tween-80 in various comparisons was used as an emulsifier in ice cream making and their effects were analyzed. The composition of the mixture was determined based on 5 types of HLB values, namely 4.5 (E1); 5.3 (E2); 6.1 (E3); 6.9 (E4); and 7.7 (E5); obtained from a mixture of MDAG and Tween-80 (87.5: 12.5); (80.8: 19.2); (74.2: 25.8); (67.5: 32.5); and (60.8: 39.2), respectively. The five treatment levels of the mixture composition of the two types of emulsifiers were arranged in a completely randomized design with 4 replications. The parameters observed were overrun, melting time, texture, and consumer preferences for taste and overall acceptance. The data obtained were statistically analyzed using ANOVA, followed by Duncan New Multiple Range Test (DNMRT) . The results showed that the composition of the mixture of MDAG and Tween-80 had a very significant effect on overrun, melting time, texture, taste, and overall acceptance of the ice cream produced. The best quality ice cream was obtained from the mixture composition of MDAG and Tween-80 at HLB 6.1 with MDAG: Tween-80 (74.2: 25.8) with an overrun value of 68.43%, melting time of 21.13 minutes, texture score of 4.76 (as good as a local commercial ice cream produced in Kumpeh District, Muaro Jambi), preferences score of taste was 5.92 (from a score interval of 1-7), and an overall acceptance score was 5.56 (from a score interval of 1-7).

Abstract

Sweet bread produced by UD. CJ Bakery has defects in the form of size, texture and color. In this study the process of improving the quality of sweet bread in UD. CJ Bakery was done by application of the six sigma and kaizen methods. The results showed that the cause of bread size defects was a less efficient cutting technique with a defect percentage of 28.97%. Color defects were caused by the length of the curing process and too high heating temperature with a defect percentage value of 20.51%, while texture defects were caused by a prolonged proofing process with a defect percentage value of 50.51%. Actions to reduce the value of product size, color and texture defects were by using good and correct cutting techniques, taking into account the time and temperature of the oven, and making a simple proofing cabinet. The sigma level before the improvement was 2.24 with a DPMO value of 259,333. After improvement, the sigma level value was 2.38 and the DPMO value was 115,600. These results showed that UD. CJ Bakery has improved its quality after implementing Six Sigma and Kaizen.

Abstract

Nutmeg oleoresin microcapsule is the solid, liquid, and gas coating technology of the nutmeg fruit.  The purpose of this study was to know how mace nutmeg oleoresin microcapsules could preserve the broiler chicken meat at room temperature during 4 days of observation. The experimental design used was a Completely Randomized Design (CRD) consisting of 5 treatments with mace concentration of nutmeg microcapsules oleoresin (0, 50, 100, 150, and 200) ppm. The variables observed were water content, pH value, total microbes, and organoleptic properties (color, aroma, and texture). The results showed that mace nutmeg oleoresin microcapsules did not affect (p> 0.05)  water content and sensory properties of broiler chicken meat, but had a significant effect (p <0.05) on the pH value and total microbe at the same day of room temperature storage. Panel organoleptic test results on the level of preference for meat color, aroma, and texture of chicken meat were in the range score of 3 (somewhat like) to 4 (somewhat dislike). The treatments of nutmeg oleoresin did not affect (p> 0.05) on color, the aroma, and the texture of broiler chicken meat. This research shows that marinating using oleoresin microcapsules has not been effective as a preservative to broiler chicken meat at room temperature. Keywords: chicken meat, mace nutmeg oleoresin microcapsules
