Abstract

One of the problems in the sugar industry is lack of low cost, simple and accurate measurement techniques for sugar recovery of sugarcane in the field or laboratory. This study investigated the potential using of bioelectrical properties as a non-destructive technique for this purpose. A parallel plate capacitor was developed to measure the bioelectric properties of sugarcane in a lateral and longitudinal position of the samples. Eighteen internode samples from 3 sugarcane varieties were measured within 0.1-10 kHz frequency range of LCR meter and then was analyzed sugar recovery in the laboratory. The result showed that in the lateral position are more capacitive and resistive than the longitudinal position. Artificial neural network (ANN) was developed for prediction of sugar recovery as a function of bioelectrical properties. The best ANN model produces a high accuracy in the lateral bioelectrical measurement position with a correlation coefficient (R) > 0.90 and mean square error (MSE) <; 0.05. It showed that the ANN model based on bioelectrical properties had the potential to be developed as a simple technique to predict the sugar recovery of sugarcane.

Abstract

Aplikasi tracking kuliner halal telah dikembangkan untuk melacak kuliner tersertifikasi halal di daerah kunjungan wisata. Aplikasi ini mengintegrasikan aplikasi Android dengan layanan Google maps dan Global Positioning System (GPS)  untuk membantu wisatawan mengetahui lokasi kuliner tersertifikasi halal dengan peta navigasi dan informasi menu makanan yang disajikan. Sistem tracking ini masih dikembangakan di daerah terbatas. Sebelum penggunaan aplikasi ini diperluas perlu dievaluasi penerimaannya oleh masyarakat. Penelitian ini menggunakan metode TAM (Technology Acceptance Model), dimana faktor yang diteliti adalah kemanfaatan dan kemudahan untuk menggunakan aplikasi. Data diolah dengan metode Partial Least Square (PLS). Hasil pengujian aplikasi tracking kuliner halal menunjukkan persepsi kemudahan berpengaruh nyata terhadap kemanfaatan aplikasi. Persepsi manfaat dan persepsi kemudahan masing-masing berpengaruh nyata terhadap minat menggunakan aplikasi. Pengguna yakin bahwa aplikasi yang mudah digunakan dan memiliki manfaat akan menarik minat masyarakat untuk menggunakan. Minat menggunakan aplikasi berpengaruh nyata terhadap penggunaan nyata aplikasi ini. Nilai predictive relevance sebesar 0,885 berarti model dinilai baik untuk menggambarkan keadaan sebenarnya di lapang.

Abstract

Jackfruit is one of tropical fruit that is widespread in the world. Jackfruit fruit had a seasonal charachteristic and very perishable, so it needed to be further processed. One of the fruit chips producers in Malang SJ produced defects in jackfruit chips that were broken 74.5% of all defects types in 2014. Six Sigma method can be applied to evaluate the quality of jackfruit chips. This study aimed to evaluate the quality of jackfruit chips with Six Sigma - Define, Measure, Analyze, Improve (DMAI) so that it was known the Sigma of production, the main factors causing the defect, the priority proposed improvement, and the alternative using of jackfruit. The result of quality evaluation obtained by Sigma of production is 2.05. Factors that cause broken of jackfruit chips were machine, material, human, and methods. Priority improvements were made by resetting rotation speed of spinner according to the standard, completed the spinner’s standard operational procedure (SOP) and selecting the right jackfruit. Jackfruit from Malang can be an alternative raw material because it produces more whole jackfruit chips.

Abstract

Kecubung (Datura metel L.) memiliki  senyawa fitokimia seperti alkaloid, tannin, saponin, fenolik, dan sebagainya. Senyawa ini memiliki manfaat farmakologis diantaranya sebagai anti mikroba, anti fungi, anti inflamasi, anti oksidan, analgesik, anastesi, dan sebagainya. Berdasar hal tersebut, kecubung diduga dapat dijadikan agen antibakteri jerawat, salah satunya Propionibacterium acnes. Penelitian ini berfokus pada optimasi ekstraksi daun kecubung menggunakan metode respon permukaan (RSM). Optimasi ekstraksi mempelajari rasio pelarut terhadap bahan (v/b) (X1)  dan lama sonikasi (menit) (X2). Respon yang diamati yaitu rendemen ekstrak kental (%) (Y1) dan aktivitas antibakteri ekstrak daun kecubung terhadap Propionibacterium acnes (mm) (Y2). Batas atas percobaan faktor X1 yaitu 15:1 dan batas bawah 5:1. Batas atas X2 yaitu 15 menit dan batas bawah 5 menit. Hasil uji Anova menunjukkan bahwa faktor rasio pelarut terhadap bahan dan lama sonikasi berpengaruh terhadap rendemen (P 0,001). Uji aktivitas antibakteri menunjukkan zona hambat sebesar 7-12 mm yang mengindikasikan bahwa ekstrak kental daun kecubung memiliki kemampuan antibakteri. Selanjutnya, optimasi rasio pelarut terhadap bahan 15:1 dan lama sonikasi 15 menit menghasilkan prediksi respon rendemen 8,155%. Pada tahap verifikasi didapat rendemen sebesar 8,262% dengan selisih 1,31% dibanding prediksi model.

Abstract

Halal food certification in the university canteen needs to prepare Halal Assurance System (HAS) implementation. Halal Control Point (HCP) traceability in the canteen is very complicated because it has several menus, processes, and materials. This study aims to trace the HCP on materials, processing and serving in Universitas Brawijaya (UB) Canteen, then provide improvement. This research used seven criteria of HAS-23102 for a restaurant to evaluate the menus, ingredients, production, and serving in UB Canteen. HCP traceability was done on 60 menus from 4 food tenants and one beverage tenant. The results showed that grouping the menus and ingredients facilitates HCP identification. The menu consists of six groups: soup, deep-fried, stir-fried, strong spices dish, medium soup, and beverages. The materials consist of fresh ingredients, dry ingredients, and liquids. The menus required 113 materials. There are 16 (14%) materials HCP, including chicken, beef, noodles, and soy sauce. HCP materials do not meet HAS criteria and be replaced with halal-certified material or halal production process (HPP) description from the producer that needs to be checked by a halal auditor. The HCP did not found in the process and serving because the canteen does not produce and service haram (unlawful) products. Still, there is contamination possibility of haram and najis (unclean in Islamic terms) materials. For prevention, the Standard Operational Procedure (SOP) of production, serving the tenant, employee, and visitor need to be applied. The alternatives are supplying chicken meat and beef from a halal-certified slaughterhouse, monitoring and controlling the tenants' kitchen periodically three months, applying the halal standard for storage in tenant's kitchen and canteen facilities, and food serving in canteen. The HCP traceability of the university canteen according to halal standards, including raw materials, additional materials, processes, and serving, including the equipment used.

Abstract

This study aimed to investigate the effect of the voltage of the pulsed electric field (PEF) and ginger extract concentration on sugar cane juice's physicochemical and organoleptic quality. The experiments were carried out at voltages of 20 kV and 40 kV, and ginger extract concentrations of 2, 4, and 6%. The PEF with 40 kV and 6% ginger extract concentration resulted in the most efficient microbial reduction by 99.54%. Sugarcane juice has a total number of microbes of 3.7x103 CFU/ml, antibacterial activity 1.48, pH of 6.26, total solids dissolved of 20.5 °Brix, a viscosity of 4.67 Cp, reducing sugar of 2.17%, brightness of 24.4, redness of 7.17, and yellowness of 8.1. The combination of pulsed electric field and ginger extract addition can preserve the shelf life and maintain sugarcane juice quality. The higher the PEF voltage and ginger extract concentration, the longer the quality of the sugarcane juice can be preserved.
