Abstract

Coffee flavor strongly influences consumers preference. Geographical location is one factor influencing the flavor of Robusta coffee. Descriptive sensory using RATA was used to differentiate the sensory profiles of several Robusta coffees. Sensomic approach by Principal Component Analysis (PCA) success- fully differentiated Robusta coffee from Jember Regency, East Java, Indonesia. It showed that Robusta from different growing locations has specific sensory characteristics. Robusta coffee from Gunung Malang, Tanggul, and Pakis was characterized by sweet and acid aromas, while coffee from Kemiri was characterized by sweet and sour taste, brown color, bitter aroma, and rough mouthfeel. Meanwhile Sidomulyo I and Sidomulyo II coffees, which were grown near each other and at similar altitudes, have similar characteristics, although the process was different. Both coffees have bitter aftertastes and bodies, burnt aromas, astringent flavors, and high levels of bitterness. In contrast, Robusta Rowosari, Tugusari, and Badean were characterized by low sweetness, sourness, bitter aroma, and rough mouthfeel.

Abstract

Abstract—Enzymes are biocatalysts widely applied in agriculture, food processing, chemical industries, and medical fields. Enzymes can be used singly or immobilized within a matrix. However, free enzymes often exhibit lower stability compared to immobilized enzymes. Therefore, this research aimed to evaluate the combined two proteolytic enzymes for extracting protein hydrolysates. The objective was to analyze enzymes' immobilization characteristics using carrageenan and determine the optimal concentration combination. Calotropin and papain were applied at concentrations of 2.5 mL, 3.5 mL, and 4.0 mL, respectively. The analysis parameters included yield, enzyme activity, soluble protein content, specific enzyme activity, stability, and kinetic parameters (Km and Vmax). The results showed that the combined proteases exhibited yields ranging from 44.43% to 48.63%; enzyme activities of 9.23–53.63 U/mL; soluble protein contents of 2.40–2.89 mg/mL; and specific enzyme activities of 3.54–18.62 U/mg protein. The enzymes were maintained stability at temperatures ranging from 30 to 60 °C. The kinetic parameters were determined as Km = 0.0034 g/mL and Vmax = 17.094 U/min.

Abstract

Papaya Calina atau Pepaya California merupakan buah klimaterik yang memiliki daya simpan yang pendek sehingga sangat mudah rusak oleh mikroorganisme. Edible coating dapat melindungi produk dari kerusakan mikroorganisme, mencegah adanya kerusakan kimiawi yang membuat produk menjadi berjamur bersifat hidrofobik dan memiliki sifat antimikroba. Kitosan memiliki sifat yang mudah mengalami degradasi secara biologis, renewable, tidak beracun, dan merupakan kation kuat, flokulan, koagulan yang baik, serta mudah membentuk membrane atau film. Tujuan dari penelitian ini yaitu membentuk Edible coating kitosan untuk melindungi pepaya dari kerusakan mikroorganisme. Edible coating kitosan diaplikasikan pada Pepaya Calina dengan tiga teknik yaitu cara pemolesan, penyemprotan, dan pencelupan. Data uji fisik dan kimia dianalisa ragam atau ANOVA dengan signifikansi 0,05 (5%) atau taraf kepercayaan 95%, apabila didapatkan perbedaan nyata, maka dilanjutkan dengan uji lanjut Duncan's Multiple Range Test (DMRT) pada taraf 5%. Nilai hasil tertinggi dari Uji de Garmo yaitu perlakuan pelapisan edible coating berbasis kitosan pada Pepaya Calina menggunakan teknik pengaplikasian pencelupan mendapat nilai 0,859 dan pelapisan edible coating berbasis kitosan menggunakan teknik pengaplikasian penguasan mendapat nilai 0,842.  Berdasarkan uji indeks efektivitas dengan bobot sebesar 0,859 yaitu jenis perlakuan edible coating kitosan teknik celup dapat bertahan ingga hari ke-9 memiliki hasil data pengujian: susut bobot 7,62%, tekstur 25,9 mm/10dtk, warna L* 55,4; warna a* 11,6; warna b* 33,7; laju respirasi 14,250 mgCO2/kg/jam, vitamin C 291,22 mg/100g, dan total padatan terlarut 18,2 ⁰Brix.

Abstract

Smart flavor is a food flavor generator made from cardinal fish which has a high content of antioxidants and protein. The research objective was to determine changes in critical water content, antioxidant activity, dissolved protein during storage and to analyze the economy and nutrition. This research used two observation variables, namely the difference in temperature (cold and room) and storage time (4 days). The results showed a decrease in critical water content, antioxidant activity, and dissolved protein for 4 days of storage at room and cold temperature. The critical moisture content at room temperature storage is 8,65-9,37% and at cold temperature storage is 7,46-8,22%. Changes in antioxidant activity at room temperature storage were 72,56-41,35% and in cold temperature storage were 75,94-41,35%. The changes in dissolved protein at room temperature storage were 5,151-2,958µg and at cold storage were 5,211-4,377µg. Economic analysis shows that the cost of goods manufactured is Rp 2.581 , BEP units 52792 , BEP rupiahs of Rp 204.393.223 , NPV of Rp 672.228.848 , net B/C of Rp 1.5 , PBP of 0,15 years.

Abstract

The unstable availability and trading system of beef has resulted in many acts of pork adulteration by irresponsible parties. This action disadvantages consumers, especially Muslim consumers. Based on this, a rapid detection method for aroma identification is needed. The rapid aroma detection in this research uses an electronic nose based on MQ3 and MQ5 sensors with Arduino Mega as a microcontroller. Digital data displayed using Cool Term software is processed using Microsoft Excel and analyzed descriptively. The sensing process uses beef and pork with a temperature of 40 to 120 oC at every 10 oC increase. Based on the results, the optimum sensing temperature to differentiate beef and pork is at 70 oC. The sensor response pattern and beef and pork flavor print showed significant differences. Using PCA analysis with a total score plot of 100% shows that the electronic nose based on MQ3 and MQ5 sensors can detect differences in the aroma of beef and pork.

Abstract

The majority of Indonesia's population is Muslim; therefore, halal food education should be instilled from an early age, particularly at the elementary school. The activity aimed to enhance students’ literacy and understanding of halal food through an educational approach implemented at Al-Munawwiriy Islamic School (AIS), Sumbersari, Jember. The activity was conducted by the Research Group (Keris E-Food) from University of Jember in collaboration with AIS. The program began with an introduction Elmarom Bread production process, continued with an assessment of students’ initial understanding, and concluded with interactive socialization sessions. Educational methods employed included visual media, group discussions, and direct observation of the halal food production process. The results indicated that this educational approach was highly effective in increasing students’ knowledge of the concepts of halal and thayyib, as well as in fostering a critical attitude in selecting food in accordance with Islamic principles. Furthermore, the program reinforced the role of schools as institutions for embedding Islamic values. Early halal education has proven to be a strategic effort in shaping a generation that is both aware of and committed to halal food consumption.

Abstract

One of the main obstacles faced by Micro, Small and Medium Enterprises in Rejoagung Village is the lack of halal certification. Although halal certification is a mandatory requirement for all food products circulating in Indonesia, many Micro, Small and Medium Enterprises in this village do not understand the importance of halal certification and have not taken care of it. In fact, halal certification not only guarantees the halalness of the product, but can also increase consumer confidence and open up wider market opportunities. To overcome this problem, efforts are needed to increase awareness of Micro, Small and Medium Enterprises about the importance of halal certification. Through the community service program, it is hoped that it can provide socialization and assistance to Micro, Small and Medium Enterprises so that they are motivated to take care of the halal certification of their products. Finally, at the end of the service, ten halal certificates were successfully issued for Business Actors who are partners of Sekolah Kopi Raisa. Thus, Micro, Small and Medium Enterprises in Rejoagung Village can develop further and make a greater contribution to the village economy.
