Abstract

Lemea is a traditional food from Rejang tribes that needs improvement in packaging so that the product can compete with other packaged foods. A study to get the proper packaging to maintain lemea’s quality using various types of packaging materials and storage temperatures is necessary to be conducted. The objective of this study is to examine effect of various types of packaging materials and storage temperature on quality changes of lemea. The study designed using CRD with 2 factors and 3 replications. Type of packaging material used in this research is LDPE plastic with a thickness of 0:01 mm, OPP / PP multilayer plastic with a thickness of 0.05 mm and PETE plastic bottles with a thickness of 1:25 mm; storage temperature used is room temperature at 27-32 °C and refrigerator temperature at 12-15 °C. Parameters measured were changes in water content, pH value, the number of colonies of microbes and organoleptic (color, scent, shape and overall acceptance attributes of lemea) on lemea that stored for 28 days with the observation point on day 7, 14, 21 and 28. Various of packaging materials of lemea are LDPE plastic, OPP / PP multilayer plastic, and PETE plastic bottles showed significant effect on moisture content, pH, TPC, and organoleptic in room temperature storage at 27-32 °C but it had no significant effect in the refrigerator temperature storage at 12-15 °C. The difference in storage temperature affects the occurrence of deviation or alteration of lemea quality.

Abstract

Cube chili has potential to be commercialized.   However, packaging of the product has not yet been prepared well for commercialized purpose. Therefore, it’s necessary to do a research about product packaging.  This research aims to obtain the best secondary packaging for cube chili, determine the level of consumer preference towards the packaging and get the information about the added value of packaged cube chilli. Selection of the best secondary packaging for cube chili according assessment from 5 experts with Analytical Hierarchy Process (AHP) method, distributing hedonic test questionnaires to 25 customers for the selection of the preferred packaging, analyzed with Kruskal Wallis method and determination of the added value packaging with Hayami method. Secondary packagings that have been used are  plastic box polistirene (PS) with thickness of 0.167 mm, folding box carton (FC) with thickness of 0.5 mm and  plastic box polistirene (PS) with thickness of 1 mm. Result of this research  showed that the best secondary packaging  according to expert assessment is PS box 1 mm (0,468).  The packaging of cube chili that most preferred by consumers is FC-box 0.5 mm (4,44). The highest added value is owned by the cube chili that packed with PS boxes 0.167 mm (51.89%)

Abstract

The research objective is to obtain the drying period of various capacities dryer to reach the best moisture content in the process of blocks dried chili production and gaining the consumer acceptance to the product. This study used a completely randomized design (CRD) with two factors: the capacity of the material and the drying time and three times repetition. The measured parameters were changes of weight during drying process, moisture content, organoleptic tests and levels of acidity (pH). The results showed that the drying periods with best moisture in the process of blocks dried chili production are drying for 8 hours at capacity of 0.3 g/cm2, 10 hours at a capacity of 0.5 g/cm2 and 10 hours at a capacity of 1 g/cm2. The highest consumer acceptance to the product for the color, aroma and overall attributes is on the blocks dried chili with a water content of 41-60%, while for the aroma is on the blocks dried chili with a water content of 61-80%.

Abstract

Lemea is one of the unique food of Rejangnese which  made from bamboo shoots  and fermented fish.  This research is  aimed to find the effect of processing and storage temperature on moisture content, pH, total microbial and consumers preferences ( color, aroma, and taste) of sambal lemea. This research carried out by using CRD with two factors namely processing (pots and bamboo) and storage temperature (room temperature and refrigerator). The results showed that the treatment gives significant effect on moisture content, pH and the level of preference (color, aroma and flavor). While the temperature did not show significant differences.  Sambal lemea which cooked in bamboo has the highest preferences score on color, aroma and flavor on days 0 and 7.

Abstract

The purpose of this study is to examine the effect of drying time in weight and water content, combination effect of drying time and size of the material, and consumer acceptance to the product in the wet processing of chili blocks production. Method used in the research is completely randomized design (CRD) with two factorials are material size and drying time. Data were analyzed using ANOVA and further analysis using DMRT at 5% significance level. Organoleptic test result was analyzed using the Kruskal-Wallis and Tukey test for further analysis. Application of the equal drying time to two different size of material: rough and finest block chili, showed the result that water content of the rough block chili is lower than the finest block chilli. Application of the different drying time duration to the same size of chili showed the lower water content with increasing duration of drying time. The water content of the material tends to decrease with increasing duration of drying time. The level of consumer’s preferences to the product of wet processing of chili blocks production is equal for scents, but it’s different for color, texture and overall preferences.

Abstract

The vinegar production needs two steps, the sugar changing to alcohol by yeast and then alcohol changing to vinegar by acetic acid bacteria. The vinegar could be produce by slow methods. The purposed of this study were to determine the influence of yeast and sugar using against the quality of fermentation result in first step (anaerobic), analyzing the influence of fermentation time against the vinegar quality based on SNI 01-3711-1995, and study the influence of fermentation time against the acetic acid content in second step (aerobic) with slow methods. This research used completely randomized design, the adding sugar (3 level) and yeast (3 level) as treatment. Each treatment was repeated three times. While the observation of vinegar quality used experiment research without the difference of treatment and repetition, used single error design. Result of research showed that vinegar quality have been suitable with SNI 01-3711-1995 about vinegar, include form, smell, acetic acid content, formic acid and oxalic acid. If the fermentation time be longer, the acetic acid content be lower in aerobic fermentation with slow methods, it was showed by the exponential regression formula ?= 20,695e-0,088x.

Abstract

Vinegar could be produced from any fruit juice. Coconut water as raw material was used by increasing sugar concentration. Vinegar is one of the alternatives in the use of coconut water waste. This is supported by the needs of the growing vinegar. Vinegar  manufacture involves two stages of fermentation (anaerobic and aerobic). Aerobic fermentation by adding yeast and sugar yield of 12% alcohol (the alcohol optimal), where as aerobic fermentation produces vinegar 4% -12.5% (SNI). The purpose of this study were to determine the optimal percentage of the addition of yeast and sugar to produce alcohol 12%, and to compare the quality of coco vinegar with SNI 01-3711-1995 vinegar. This study used factorial completely randomized design , the adding sugar and  yeast as treatment, 3 level of adding sugar and  yeast with 3 observations. Results of variance analysis  showed that the treatment was very real effect on levels of alcohol and alcohol pH. The Duncans Multiple Range Test (DMRT) showed that the highest quality levels of alcohol present in addition of 16% sugar and   6% of yeast. while the pH of alcohol contained in the addition of yeast 4.5% and sugar 10%
