Abstract

The purpose of this study were to analyze the quantity of microorganisms in some local ragi tape and determine the panelists' acceptance of the "tape jusinta" was produced. This type of research is an experiment with a solid substrate fermentation method. The used ragi tape is 4 kinds of local ragi tape from South Sulawesi Province (ragi tape A, B, C, and D) and 1 type of local ragi tape from Southeast Sulawesi Province (ragi tape E). The Tape Jusinta was produced by fermentation of a solid mixture of purple sweet potato and cassava tubers in a ratio of 1: 1 using 5 kinds of local ragi tape. Analysis of microbial quantity in ragi tape includes the number of molds, yeasts and bacteria in viable count using the Standard Plate Count (SPC) method. Panelist acceptance of the Tape Jusinta product was analyzed using the Hedonic test with a numerical scale range of "6". Data were analyzed descriptively and inferentially using Anova and Duncan's Multiple Test. The results of the data analysis showed that the level of palatability of the panelists to the tapejusinta  fermentedragi tape B was not different from the tape jusinta fermented ragi tape A and C, but the tape jusinta fermented by Cragi tape was different from the results of fermentation ragi tape D and E. The “tape jusinta” fermented ragi tape B is preferred over the tape jusinta fermented ragi tape A, C, D and E with the highest average panelist rating of 4.15. The quantity of microorganisms on ragi tape B are mold types as much as 1.0 x 104 cfu / g, yeast 8.0 x 103 cfu / g and bacteria 5.7 x 104 cfu/ g. Keywords: cassava roots, purple sweet potatoes, ragi tape, "tape jusinta", palatabilityAbstrakTujuan penelitian adalah menganalisis kuantitas mikroorganisme pada beberapa ragi tape lokal dan mengetahui daya terima panelis terhadap “tape jusinta” yang dihasilkan.

Abstract

The Cocoa pod husk (CPH) is a processed cocoa fruit waste, containing lignocellulosic biomass which can be pyrolysis to produce liquid smoke. The purpose of this study was to obtain antibacterial material from liquid smoke using the CPH pyrolysis method. This research method includes: preparation by drying the CPH raw materials for 5-7 days and then chopping the CPH sample dry. Furthermore, the pyrolysis process is carried out at 385-500 °C with a heating flow rate of 6 °C/min. The liquid smoke crude obtained is filtered and distilled fractionated to produce clearer liquid smoke. Analysis of Total Phenolic Content (TPC) of liquid smoke was carried out by the Folin-Ciocalteu (FC) method using gallic acid standards and Ultraviolet-Visible spectrophotometer instruments at maximum wavelength (λmax) 765 nm. The CPH liquid smoke antibacterial test was carried out using a dilution method with variations in liquid smoke concentrations of 5, 7, 10and 15%. The TPC of CPH liquid smoke is 1.035 g / L.The spectrogram analysis of Gas Chromatography-Mass spectroscopy (GC-MS)  of CPH liquid smoke shows the presence of compounds:acetic acid, Methyl glyoxal,Pyridine, 4-methyl- pyridine,  4-[2(methylamino)ethyl]- Phenol.The results of the analysis of the minimum inhibitory concentration (MIC) of CPH liquid smoke against Escherichia coli and Staphylococcus aureus bacteria were obtained at a concentration of 15%.This study shows that pyrolysis extraction can be used as a technique for obtaining extracts of phenolic compounds from CPH and is promising for safe antibacterial agents.Keywords: CPH, liquid smoke, pyrolysis, Phenolic, antibacterial.Abstrak Kulit buah kakao (KBK) merupakan limbah hasil olahan buah kakao, mengandung biomassa lignoselulosa yang dapat dipirolisis menghasilkan asap cair.Tujuan penelitian ini untuk mendapatkan zat antibakteri dari asap cair dengan metode pirolisis KBK.
