Abstract

Cookies are a type of dry cake that is similar to biscuits and is popular in Indonesia. This research aims to determine the effect of the concentration of sorghum flour and katuk leaf flour on the physical, chemical and hedonic properties of cookies and determine the product with the best treatment. This research used a Randomized Block Design with 5 treatments adding katuk leaf flour (0%, 5%, 10%, !5% and 20%) and 3 replications. The research results showed that the concentration of sorghum flour and katuk leaf flour had a significant effect on the hedonic test and the hedonic quality of color, taste and aroma, as well as on the color test results (L, a, b). However, it had no real effect on water content, carbohydrates, protein, texture as well as hedonic tests and hedonic quality of texture. Treatment P1, namely adding 5% katuk leaf flour to the cookies, gave the best results from the hedonic test and hedonic quality and color (L, a, b).

Abstract

The extremely low frequency (ELF) magnetic field exposure technology for food processing and preservation is a future technology that produces better food quality. This research aims to examine the exposure of extremely low frequency (ELF) magnetic field waves to pasteurized cow milk and its effect on pH, chemical content, total microbial count, and sensory tests. This research was carried out by exposing ELF waves of 834.8 micro Tesla (μT) for 90 minutes to fresh milk and pasteurized milk. Samples were stored at room temperature then observed at 0, 2, 6, and 21 hours. Each treatment was repeated three times. The results showed that exposure to ELF waves had no effect on chemical content (P<0.05). The pH measurement shows that exposure to ELF waves could maintain the pH value. The total microbial count showed that exposure to ELF waves had an effect on reducing the total microbial count. The organoleptic test showed that pasteurized milk exposed to ELF waves had a smaller level of change. Based on observations, exposure to ELF waves has the potential to be developed in pasteurization, storage of cow milk, and retain its nutritional content. Keywords: Cow milk, Exposure, Extremely low frequency, Influence, Pasteurization.

Abstract

Fisheries are sector with great potential to meet food needs. Teaching Factory Canning Politeknik Negeri Jember (Polije) is one of the Fish Processing Units (UPI) engaged in canning seasoned sardines. Teaching Factory Canning Polije is a UPI included in the medium-large category. This research aims to determine the processing feasibility of canning teaching factory. Data were collected by interview and checklist analysis referring to the Ministry of Marine Affairs, namely the Decree of the Minister of Marine Affairs and Fisheries No.Kep.01/MEN/2007. The application of basic eligibility requirements is carried out by analyzing whether there is a discrepancy with existing regulations or deviations, which are then synchronized with the value of the eligibility criteria. The production process of Teaching Factory Canning has followed the processing feasibility certification set by KKP No.Kep.01/MEN/2007 with good eligibility criteria. The assessment is based on 6 minor deviations, 7 significant deviations, and 1 serious deviation. In addition, the GAP Analysis of the UPI TEFA Canning Polije Processing Feasibility Certification showed that the basic feasibility had met the basic requirements and 1 general requirement by correcting the deviations found

Abstract

Mango (Mangifera indica L) is one of commodities with high food loss rate due to the characteristics of mango, which is easily spoiled and difficult to store. One of the strategies to reduce mango food loss caused by post-harvest handling is the diversification of mango products. Mango flour can be developed to minimize mango food waste and enhance its added value. This study aimed to determine the optimum formulation for making mango flour. The study used Response Surface Methodology (RSM) type Central Composite Design (CCD) to optimize mango flour yield, using three factors: rice flour concentration (X1: 2 5%), maltodextrin concentration (X2: 2-5%), and tapioca flour concentration (X3: 2-5%). The significance of response was carried out using analysis of variance (ANOVA) at the 95% confidence level (p<0.05). The linear model was the model suggested by software. Model analysis showed that rice flour and tapioca flour concentration significantly affected mango flour yield, while maltodextrin did not have a considerable impact. Based on the results of this study, the optimum conditions in making mango flour were found using rice flour concentration of 4.94%, maltodextrin concentration of 2.25%, and tapioca flour concentration of 4.88% to produce mango flour yield of 20.9578%. Keywords: Mango flour, Optimization, Response surface methodology, Yield.

Abstract

Pada umumnya brownies terbuat dari tepung terigu. Penggunaan tepung terigu semakin meningkat di Indonesia. Namun tidak semua masyarakat dapat mengkonsumsi gluten, seperti penyandang penyakit autis dan intolerant gluten. Untuk meminimalisir penggunaan tepung terigu, dapat menggantikan tepung terigu dengan tepung yang terbuat dari umbi yang tumbuh di Indonesia seperti tepung talas dan tepung sagu. Penelitian ini mempelajari tentang pengaruh perbandingan penggunaan tepung talas dan tepung sagu pada karakteristik fisik, kimia, dan sifat organoleptik paling disukai panelis agak terlatih dalam pembuatan brownies cookies. Hasil obsevasi analisis sidik ragam terhadap perbandingan tepung talas dan tepung sagu pada pembuatan brownies cookies memberikan pengaruh nyata terhadap sifat fisik dan kimia yaitu tekstur, kadar air, kadar abu, kadar karbohidrat, kadar protein dan kadar lemak. Perlakuan terbaik dari variasi penggunaan tepung talas dan sagu adalah 80:20 dari hasil tes hedonik atau penerimaan panelis agak terlatih. Sehingga dapat disimpulkan bahwa formulasi tepung sagu dan talas dengan variasi perbandingan 20:80 dapat memberikan prospektif baru dalam pembuatan brownies cookies yang bebas gluten
