Abstract

The objective of this research was to determine the shelf life of the traditional snack food “rengginang” using the Labuza Model (the accelerated storage studies method (ASS Method)), as well as comparing the results with the extended storage studies (ESS) method. The rengginang was packed with the polyethelene plastic 0.03 mm, and store at room temperature with 75% of RH. The shelf life was determine using the accelerated storage studies method with Labuza Model, and extended storage studies method. The parameters observe in determination of shelf life were initial moisture content, critical moisture content, equilibrium moisture content, slope of sorption isotherm curve, moisture permeability of plastic used, ratio of plastic package are and product weight, and saturated pressure of storage condition. The result showed that the shelf life of rengginang calculated using Labuza Model (ASS Method) was 39 days, while the ESS method resulted 46 days. These was indicating that the Labuza model can be used to predicting the shelf life of rengginang like snack food.

Abstract

This research was aimed to study the effect of using the tempe flour to substitute the wheat flour on the characteristic of breads produced, as well as to know how much the tempe flour can be used to substitute wheat flour in order to breads that could still be accepted by panelist with the best characteristic. This research was design using Randomized Block Design with 6 level substitutions treatments, namely: 100% wheat flour : 0% tempe flour, 98% wheat flour : 2% tempe flour, 96% wheat flour : 4% tempe flour, 94% wheat flour: 6% tempe flour, 92% wheat flour : 8% tempe flour, 90% wheat flour : 10% tempe flour. There were three replications of each treatments, so that be 18 experiments unit. The data was analyzed with ANOVA and followed by Duncan’s Method if the treatments effected the parameter. The research showed that substitution treatment up to 96g wheat flour: 4g tempe flour has result breads with the best characteristic in which leavening bread loaves was 404,83%, water content was 36,62(%w/w), ash content was 0,72(%w/w), and protein content was 9,31(%w/w). According to sensory analyzed of the breads produced, the colour of breads were yellow-brown, flavor were neutral, like of taste, texture were moderately soft, sponge formation were moderately variant, and overall acceptance were like.

Abstract

The purpose of thus research were to find out the formulation of extract of curcumin and tamarind leaves which had an optimum antioxidant activity. The observations were undertaken on the phenol values, radical scavenging activity, antioxidant activity test with FTC method, antioxidant activity test with TBA method, water content, and pH. The result showed that the formulation of curcumin and tamarind leaves had influence to the phenol values and the radical scavenging activity. Addition of curcumin and tamarind extract in FTC and TBA methods showed that the formula was successful to purpose lipid oxidation. The highest phenol value (18.51%) was found in R9 which consisted of 20% curcumin extract and 80% of tamarind leaves extract, meanwhile the phenol value of 100% tamarind leaves extract was 9.05%, and the phenol value if 100% tamarind leaves extract was 5.34%. The highest radical scavenging activity (0.27%) was found in R8 which consisted of 30% curcumin extract and 70% of tamarind leaves extract, meanwhile radical scavenging activity of 100% curcumin extract was 0.17% abd the 100% tamarind leaves was 0.23%.

Abstract

The objective of this research were to know the content of vitamin C, and the consumer preferences on several combination of fresh cutting fruits that were packed in several types of packaging during shelve life. This research was undertaken by factorial experiment using randomized block design. There were three factors in this research namely: (i) combination of fruits (water melon and rock melon; water melon and papaya; rock melon and papaya); (ii) types of packaging used (without packaging; mika; stretch film); and (iii) duration of shelve life (10 hours; 20 hours; 30 hours). Analysis was undertaken on vitamin C contents, and organoleptic test on several parameters namely colour, aroma, texture, taste, and overall acceptance. The research result showed that the combination of fruits, types of packaging and duration of shelve life were significantly affecting the vitamin C content. The most stable of vitamin C content was found in the fruits combination of water melon and papaya which was packaged by using stretch film within 10 hours. The highest overall acceptance was found in the fruits combination of water melon and rock melon which was packaged by using mika within 10 hours of shelve life.

Abstract

A green house that roofed by using transparent materials such as glasses, fiberglass, plastic, etc. could provide an optimum growth environment for plants such as mushrooms. However, green house effect during the day leads to a higher temperature inside the green house in comparison to the outside temperature. In order to provide an optimal environment for growing mushrooms in a green house, it is required a temperature machine control which is able to bring the room temperatures between 160C to 210C. The dynamic of room temperature can be predicted by using a mathematical model simulation. A stimulation model developed by using Matlab program could be implemented in a temperature control machine in order to bring the room temperature between 160C, 190C and 210C. Research results showed that it took 16.8 minutes, 26.4 minutes, and 30 minutes to bring the room temperature down to 160C, 190C and 210C respectively. When the room temperature reaching the target temperature, the room temperature were varying within 0.010C.

Abstract

This research objective was to know the profile of an area which will be developed as an agro-tourism area in order to increase the economic activities of the area. The profile of the area was studied through a potency analysis by using a factor analysis on several economic potential namely agro-estate, industry, and tourism. Meanwhile, the projection analysis od estate commodity production and tourism arrival when using a forecasting method. Jembrana Regency has some centers of estate commodity which could developed as an agro-tourism area. This potency is also supported by the existence of industrial sector and the increasing trend of tourism arrival. So that, development of new tourist objects, such as agro-tourism at Jembrana Regency is still prospective.
