Abstract

Taro flour is one of dried products of taro (Colocasia esculenta L.). The characteristics of taro flour that low water content has an important role in determining the storage time. The presence of water in materials is influenced by internal factors of material, processing, moisture of storage and packaging materials. The water level reduction technique commonly used is by drying process, one of them is by using a tray dryer machine. The aim of the study was to analyze the physical properties, and nutritional content of taro flour produced from drying taro chips using a tray dryer machine at a drying temperature of 50°C, 60°C and 70°C with drying times 5, 6, and 7 hours. The physical parameters observed were water content, density and color, the nutritional parameters observed were protein, fat, ash, carbohydrates and crude fiber. The results of study showed that the water content ranged from 6.14 - 8.34%, density ranged from 0.45 - 0.57 kg/m3 and the lightness parameter values ranged from 69.9 - 72.0, with redness values between 12.2 - 12.8 and yellowness values between 11.5 - 13.1. The highest values of protein, fat and carbohydrate were 8.34%, 0.38% and 86.94%. The highest ash and crude fiber values were 3.84% and 2.99%.

Abstract

Sari tebu hijau merupakan diversifikasi produk olahan tebu hijau. Pada proses pastuerisasi sari tebu hijau dapat dilakukan dengan dua cara yaitu termal dan nontermal. Kandungan tertinggi pada sari tebu yaitu gula sebesar 75-92 %, bila dipanaskan dengan metode termal adanya ion OH- akan terjadi proses dekomposisi diawali dengan pembentukan asam organik (asam laktat) diikuti senyawa kompleks yang akhirnya dapat menghasilkan warna coklat. Berdasarkan hal tersebut dibutuhkan alternatif pengolahan sari tebu hijau nontermal. Salah satu pengolahan nontermal menggunakan Pulsed Electric Field (PEF). Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi tegangan dan frekuensi PEF terhadap kualitas sari tebu hijau, serta untuk mengetahui kombinasi tegangan dan frekuensi PEF yang paling tepat agar dihasilkan kualitas sari tebu hijau yang terbaik. Hasil penelitian menunjukkan bahwa tegangan (< 40 kV) dan frekuensi (< 40 kHz) yang rendah pada perlakuan PEF tidak berpengaruh signifikan terhadap total mikroba, total padatan terlarut, total gula, viskositas dan warna pada sari tebu hijau. Perlakuan terbaik pada penelitian ini yaitu perlakuan PEF menggunakan tegangan 40 kV dan frekuensi 40 kHz. Hasil perlakuan terbaik pada pengujian TPC pada perlakuan PEF tegangan 40 kV dengan frekuensi 40 kHz yaitu 87,48 % dengan total mikroba 8,5 x 106 cfu/ml. Penurunan total mikroba pada tegangan 40 kV dan frekuensi 40 kHz sebesar 0,9 log cycle, dengan karakteristik pH yaitu 5,83, total padatan terlarut (TPT) sebesar 13,4 derajat Brix, viskositas sebesar 5 Cp, warna kecerahan (L*) sebesar 23,55, kemerahan (a*) sebesar 7, kekuningan (b*) sebesar 7,3, dan total gula sebesar 12,24 %.Kata Kunci: Frekuensi, Pulsed Electric Field (PEF), Sari tebu hijau, Tegangan, emerging processing

Abstract

The Deep Flow Technique (DFT) method combined with the Nutrient Film Technique system. The purpose of this service activity is the first to organize training on the manufacture of simple DFT-NFT hydroponics, with methods and materials that are safe to use and serve as material for debriefing and providing entrepreneurial motivation for community groups in Malang district. The implementation of this service is at SMP N 1 and SMPN 5 Karangploso, Malang Regency. The webinar participants were attended by 61 participants consisting of 8th and 9th grade students, accompanying teachers, and a team of service lecturers. As for the results of this activity 81% of the webinar participants are familiar with the pattern of farming using the DFT NFT hydroponic system well. So that participants have benefited from this activity and these academics are able to apply knowledge to society significantly.

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.

Abstract

In the past few years, 5-Hydroxymethylfurfural (5-HMF) has been used in many industrial practices as a substitution for plastics and a versatile precursor for synthesis into a variety of value-added chemicals and fuels. The potential use of glucose monomers from cassava (Manihot uttilisma) as a potential source for 5-HMF production needed to be considered. Deep Eutectic Solvent (DES) is natural, environmentally friendly, easy to obtain, and it was used as a solvent to increase the 5-HMF yield. Therefore, the objectives of this research are to obtain the 5-HMF from cassava flour with the suitable molar ratio of the DES solvent and to analyze the effect of the addition of DES solvent on the yield of 5-HMF. The synthesis of DES was based on choline chloride with ethylene glycol with a molar ratio of 1:2, 1:3, and 1:4 and was suitable for use as a solvent in the 5-HMF dehydration process. The ratio of glucose: DES of 1:6 affects the 5-HMF yield with the highest yield was 78.61% at a glucose concentration of 51.24% and the lowest without DES was 44.49% with the same glucose concentration.
