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

The research objective is to examine the best materials of primary packaging for beledang fish crackers and measure its value added. The packaging used in the research are plastic PP (Polypropylene) with a thickness of 0.09 mm, rigid LDPE (Low Density Polyethylene) plastic with a thickness of 0.36 mm, OPP multilayer (Oriented Polypropylene) with a thickness of 0.06 mm, aluminum foil packaging with a thickness of 0.04 mm and plastic vacuum with a thickness of 0.02 mm. Respondents in the study were experts respondents consist of one academic person in food packaging subject, one practitioners in food industry (owners of the fish industry beledang chips) and three person of BPPOM practitioners in Bengkulu. The results showed that rigid LDPE plastic is considered to be the best packaging. The value-added on beledang fish crackers for using rigid LDPE plastic is 51504.48 USD / kg or increase of 49.05%.

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

The research objective is to obtain the new method with highest productivity; determine the normal and basis hour in order to get the best working hour with highest productivity; and to determine number of worker need in each section based on its workload to get the balance in production line. Time measurement was done using a technique based on stopwatch and workload measurement analysis method. The balancing of production line was done by trial and error method. Initial conditions in production line indicate an imbalance with 2312,18 seconds idle time, 51,60% efficiency of production line and 48,39% balance delay. The balancing of production line resulted 1585,77 seconds of idle time, 45% efficiency of production line and 55% balance delay. There are eight permanent workers in this home industry with labor productivity at station I is 6,42% units / man-hour before repairs and 8,57% units / man-hour after repairs, resulted the increase in productivity by 33,48%. Labor productivity at station II, III and IV before repairs is 87,5% and after repairs is 116,62% resulted the increase in labor productivity by 33,28%.

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.
