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

Rice farming is susceptible to failure due to several risks including natural disasters of flood and drought as well as pest and disease attacks. Risk mitigation such as agricultural insurance is required to cope with the risks. This study aims to portray rice production risks to failure and farmer’s perception on the implementation of agricultural insurance in Bali province. Three regencies were selected purposively based on the area insured. A survey was conducted to 180 respondents who paid for the agricultural insurance (AUTP). Data were analyzed using descriptive qualitative analysis and chi-square test. Results of the research show that most rice farming risks to failure in Bali were blast and rat attacks. In terms of agricultural insurance implementation, all farmers accept the program as a mitigation risk to bridge rice farming failure. However, most farmers (85 %) asked for fully support of premium subsidy from the government while the rest agreed to pay for a-20 % of the premium. The result from the Chi-square test shows insignificant, implying that the distribution of farmers’ perception towards full subsidy of agricultural insurance is indifferent across locations. Implication of the study noted that the government and insurer need to socialize the agricultural insurance program more intensively covering premium payment, coverage and claiming.Keywords: production risk, agricultural insurance, farmer’s perception, AUTP, Chi-square

Abstract

Dacrycarpus imbricatus Blume is a member of the Podocarpaceae family. In Bali, D. imbricatus was found in Bukit Tapak, Tabanan Regency. This species is one of the dominant species in Bukit Tapak. This study aimed to determine the genetic variation of D. imbricatus in Bukit Tapak using molecular markers RAPD (Random Amplified Polymorphic DNA). The genetic diversity of D. imbricatus needs to be studied to obtain the information used for the conservation of this species. Leaf samples were taken from Bukit Tapak, Candikuning, Baturiti, Tabanan Regency, Bali. DNA was extracted using the CTAB method, followed by extraction using chloroform: isoamyl alcohol. DNA precipitation was carried out using ethanol. RAPD analysis was performed using polymerase chain reaction (PCR) using four primers. PCR products were visualized using agarose gel electrophoresis and ethidium bromide staining. The results showed that the amplified DNA bands ranged from 1 to 5 bands with DNA band sizes ranging from 230 bp - 422 bp. Only OPA4 and UBC106 primers can be used to detect D. imbricatus diversity based on the H, D, and R values. The detected genetic variation is low, as indicated by an average polymorphism of 32.5% and similarities between samples ranging from 0.51 to 1

Abstract

Abstract Light is the main energy source for plants for the photosynthesis process. In indoor cultivation systems (plant factories), LEDs can be used as artificial light. The dominant light colors absorbed by plants for the photosynthesis process are red and blue, but the proportion of the LED colors used is unknown, so it is necessary to research the proportions of light colors. This study aims to determine the effect of the proportions of red, blue, and white light on the chlorophyll content (SPAD value) and the canopy area of Pakcoy. Pakcoy was planted in a growth chamber and given seven different proportions of light for 12 hours with a lamp total of 60 Watt and light intensity of 2000 lux. This study was conducted for 49 days, and the observations to make once a week. The results showed the proportion of red, blue, and white LED light treatment affects the chlorophyll content and canopy area. The proportions of LED light 30 Watt red, 20 Watt blue, and 10 Watt white produced the highest chlorophyll content (35.0 SPAD value) and canopy area (70.7 cm2). In conclusion, the proportion of red, blue, and white LED light showed significantly different in the growth of Pakcoy.
