Abstract

Ikan merupakan produk pangan yang cukup potensial di Indonesia. Salah satu yang berperan dalam industri perikanan yaitu TEFA (Teaching Factory) Fish Canning di Politeknik Negeri Jember. Produk baru yang dikembangkan dalam tahap penelitian saat ini yaitu ikan lemuru bumbu kuning dalam kaleng. Namun, produk ikan kaleng TEFA Fish Canning ini belum dikaji umur simpan sehingga akan berbahaya jika dikonsumsi oleh konsumen dalam waktu yang melebihi expired date. Penelitian ini dilakukan untuk mengetahui mutu dari ikan lemuru bumbu kuning dalam kaleng yang diuji dengan melihat kadar protein selama penyimpanan. Penurunan protein dapat digunakan sebagai parameter kerusakan suatu bahan makanan. Penyimpanan dilakukan selama 1 bulan dengan pengamatan yang dilakukan setiap 7 hari hingga 28 hari. Hasil penelitian menunjukkan bahwa mutu ikan lemuru bumbu kuning dengan parameter pengujian kadar protein didapatkan mengalami penurunan dengan meningkatnya suhu (30⁰C, 45⁰C, dan 60⁰C) dan lawa waktu penyimpanan (0, 7, 14, 21, dan 28 hari). Hasil pengujian arrhenius menunjukkan jika produk ikan lemuru bumbu kuning dalam kaleng dapat memiliki umur simpan sebesar 224 hari dengan kondisi penyimpanan 30⁰C.

Abstract

The use of enzymes in Indonesia is increasing rapidly and is used in various industries, especially FCMG. One of the enzymes that is widely used is xylanase, which is an extracellular enzyme that can hydrolyze xylan into xylose and xylo-oligosaccharides. This research aims to determine the optimum conditions for the xylanase production process from coffee cherry processing waste (CCPW) using Trichoderma viride through solid fermentation. The research method used was experimental using central composite design (CCD) in Design Expert 13.0 software. The treatment designs used were fermentation times of 24 hours, 48 ​​hours, and 72 hours; and substrate concentrations of 25%, 50%, and 75%. The experimental response analysis design was enzyme activity, protein content, and specific activity. The results of the research show that the optimum conditions for xylanase production are at a substrate concentration of 75% and a fermentation time of 24 hours with a desirability value of 0.742, which produces an enzyme activity value of 36.388 U/mL and a dissolved protein content of 0.494 mg/mL with a specific activity of 73.660. U/mg. The verification results show conformity with the formula predicted by the Design Expert 13.0 software, namely enzyme activity of 36,292 U/mL and protein content of 0.488 mg/mL with a specific activity of 74,369 U/mg

Abstract

Indonesia is the 4th largest coffee-producing country in the world. Coffee cherry can produce 60% CCPW, more than the core product of coffee beans as the main product produced. CCPW contains lignocellulosic material that can be converted into value-added products. This research optimizes the production of xylose and xylanase enzymes as an integrated process with a biorefinery model to increase the added value of CCPW using the Research Surface Methodology (RSM). Enzyme production is carried out using a bioprocess using Trichoderma viride. Xylose production is carried out using the dregs of xylanase production as raw material and xylanase enzymes which are produced in the integrated process. The xylanase and xylose produced are in the liquid phase. The treatment design for xylanase production is substrate concentration and incubation time, while for xylose production it is substrate concentration and xylanase concentration. Based on the optimization conducted, the optimum condition of xylanase production was 75% substrate concentration with an incubation time of 72 hours, which will result in xylanase an enzyme with an activity of 29.275 U/ml with desirability of 99.55%. On the other hand, the optimum condition of xylose production was 12.54% substrate concentration with a xylanase concentration of 4.01%, which will result in 0.53 g/L xylose content with desirability of 94.06%. These findings show that xylose production efficiency can be achieved through integrated two-stage biorefinery production for efficient and sustainable utilization of CCPW.

Abstract

Edamame is included in perishable products or products that have a fairly short shelf life if post-harvest processing is not carried out. One of the post-harvest processing methods commonly used by the community is drying. The purpose of this study was to analyze the drying process of edamame related to the MLRL and ANN models. This study used a completely randomized design (CRD) with three variations of air velocity, namely 1 m/s, 3 m/s, and 5 m/s. Data collection was repeated three times every 30 minutes until 330 minutes.  Multiple linear regression (MLR) model training and validation produce accuracy values of 88.03 and 82.23, and the value of R2 of 0.93 and 0.90. While the training and validation of the artificial neural network (ANN) model resulted in accuracy values of 88.34 and 82.15, and R2 values of 0.93 and 0.90. Keywords:    ANN, Drying, Edamame, Food  dehydrator

Abstract

Understanding the development planning priorities and commodity sub-sector in Jember Regency, it is necessary to acknowledge the prime sub-sector and the primary commodity sector in Jember Regency. Regional products should be able to prioritize the sub-sector and the preferred crop, prime and which is considered a sub-sector basis to optimize the food security in the region. The research was conducted from 2016 to 2021 by several analysis methods: Location Quotient, Analytical Hierarchy Process, and Exponential Comparative Method. The criteria used are based on seven normative criteria. The results showed that plantation and horticultural crops were the basis of sectors in the 2016-2020 survey, with values of 2,1036 and 1,3879. Based on the analytical hierarchy process and exponential comparative method analysis, it is seen that there are many leading commodities in the agriculture sector. These commodities are orange fruit, durian, banana, mushrooms, chili, coffee, and sugarcane.

Abstract

Xylose is a sugar obtained from breaking down hemicellulose. It is a polysaccharide found in the cellulose fibers of plant cell walls. One example of a plant containing hemicellulose is coffee, especially its waste called Coffee Cherry Processing Waste (CCPW). Its process's 10 L capacity production design was carried out to establish its mini factory. The financial feasibility study of each processing unit was designed. The research method used was quantitative methods. Apart from that, the approach used in this research is descriptive. The test results show that the crystalline xylose sugar processing unit is feasible to develop because the calculation results of the financial feasibility criteria are met with NPV > 0, B/C > 1, IRR 51%, PBP for two months < 5 years, which means the business owner could have returned his capital before the project period ends and BEP Q of IDR 15,565,013.54 while BEP Rp IDR 22,002479.88 was declared feasible because the BEP value was lower than the net income from xylose crystal sugar.
