Abstract

Abstract — Coconut stick insect, Graeffea crouanii (Le Guillou) is one of the important pests of coconut palms in Fiji. It causes extensive leaf damage resulting in production losses. The field surveys revealed the presence of several naturally-occurring natural enemies (predators and parasitoids) on G. crouanii in the major coconut growing regions in the Fiji Islands viz., Viti Levu, Vanua Levu and Taveuni. Two species of egg parasitoids, Paranastatus verticalis Eady and Paranastatus nigriscutellatus Eady were recorded as the most prevalent natural enemies, of which P. verticalis was the dominant species. This paper presents information from field and laboratory studies on the pest and dominant natural enemy and role of P. verticalis on the population suppression of G. crouanii in Fiji. The release of P. verticalis and field sanitation were the two best management practices identified that contributed to the improvement of plant health toward the management of G. crouanii. Keywords — Cocos nucifera L., Coconut stick insect pest, Graeffea crouanii, natural enemies, Paranastatus verticalis, Fiji.

Abstract

The demand for organic food in Indonesia is increasing annually. Organic rice is one of the most consumed organic foods in Indonesia. Organic rice perceive as healthier than conventional rice; however, in the context of the food system (from farm to fork), is organic rice better than conventional rice? To what extent does the transition contribute to sustainability? We have been investigating organic rice in the context of the food system since 2016. Our experiment reveals that (1) organic rice fits the organic principle in the level of farming where less pesticide, better farmer income and protecting biodiversity (2) lower degree of milling in organic rice resulted in the highest nutritional benefit (3) consumer perception depend on nutritional information From this point of view, we conclude that organic rice would be fit for the organic food principle and sustainable way if the rice has a lower degree of milling. Keywords—organic food systems, organic rice, contaminant, cultivation, processing, consumer preference, Indonesia

Abstract

Abstract— Tempe is a traditional indigenous fermentation food from Indonesia. The addition of rice bran as raw material for soybean mixture aims to improve functional properties of tempe. The sensory description and sensory mapping of four formulations rice bran tempe were measured. Seventy-five consumers were recruited to participate in the projective mapping of rice bran tempe cookies at the sensory laboratory of Universitas Bakrie, one of the private universities in Indonesia. The test consists of a descriptive evaluation of products with sensory attributes: taste, color, flavor, texture and aftertaste. Data was used to develop a preference map for rice bran tempe cookies. The cookies formulation consist of rice bran tempe without any addition (RBT1), rice bran tempe with cocoa powder (RBT2), rice bran with dates extract (RBT3), and rice bran tempe with cocoa powder and dates extract (RBT4). Results from preference mapping showed that the position for each rice bran tempe cookies formulation show differently with commercial products. The map shows RBT1 and RBT2 cookies have higher consumer preferences (elevation 40) than RBT3 cookies (elevation 30) or RBT4 cookies (elevation 20). Average overall acceptance scores for the four samples ranged from 4.37 to 4.81 on a 1-9 scale. The addition of rice bran tempe to the cookies formulation has not been accepted by the consumers due to the sensory attributes of bitter taste, dark color, aroma like animal feed, hard texture and bitter aftertaste. The presence of cocoa powder and dates extract has not been able to increase consumer preference of the tempe rice bran cookies.

Abstract

The variation of forest conditions shows structural differences, species composition, and potential value as well as stand density. The need and important role of stand structure model in forest management, particularly in forest-based product regulation become the supply demands quantitatively for various forest conditions in Indonesia. The objective of the study was to determine the stand structure model of dry forest. The study was conducted at the dry forest of Binafun, Bonmuti, Letkole and Oelbanu, East Nusa Tenggara Province. Determination of the best stand structure model based on maximum likelihood function of family distribution that tested including the function of exponential, gamma, lognormal and Weibull. A total of 2097 tree individuals, its representing 94 species, 72 genera and 45 families, were found in the research sites. Eucalyptus urophylla were found to be the most dominant species in the research sites and Elattostachys verrucosa have potential to replace Dryobalanops aromatic. Most of family distribution models can describe the stand structure in research sites. The models presented here are the basis for further developments toward the tree diversity for general purpose in tropical dry forest management of East Nusa Tenggara, Indonesia.

Abstract

Climate variability is one of the factors that directly and greatly affect cropping system and plant yield. It is therefore very important to obtain a good understanding about climate variability or changes in the climate and the effect of these changes to clearly understand the vulnerability of food crops as well as its agronomic impacts for us to create and implement adaptive strategies to mitigate its negative effects. This study assessed the effect of climate in rice crop yield in both irrigated and rainfed ecotype farming system in Nueva Ecija Province in the Philippines using semi-annual yield data and the different climate variables such as seasonal rainfall, mean temperature, minimum temperature, and relative humidity by using empirical/statistical method through time series analysis, and correlation analysis. Results indicated that rice yield for irrigated and rainfed ecosystem type of farming in Nueva Ecija show an overall increasing trend from year 1991-2018, although there are observed decline and fluctuations in some years. The different climate variables (i.e., rainfall, temperature, and humidity) show fluctuating trends and irregularities spanning from the year 1991-2018. But it showed overall decreasing trends for relative humidity and increasing trends for rainfall, minimum temperature, and mean temperature. There are significant correlations between rice yield the all the climate variables in both irrigated and rainfed farming ecosystem types.

Abstract

Black rice is an alternative staple food better than white rice. It has lower carbs, but higher antocyanin compared to white rice. Nowadays, black rice consumption has increased, production needs to be increased to accomodate the demand. But, to our knowledge, there is lack of information about black rice resistance against biotic stresses, one of black rice cultivar is Cempo Ireng. This information needed for optimal Cempo Ireng cultivation. In this research, we determined chlorophyl content and analyzed OsNPR1 expression of three cultivars: Java14 (resistant control), Cempo Ireng, and IR64 (susceptible control), against Xanthomonas oryzae (Xoo). All of them were sprayed with salicylic acid (SA) before inoculated with Xoo. IR64 24h had the lowest chlorophyll content (0,576 ± 0,066 mg/g), meanwhile Java14 72h had the highest content (2,358 ± 1,301 mg/g). However, all the cultivars did not show any correlation between them and time after Xoo inoculation. OsNPR1 expression did not show any significant change in Java14 and Cempo Ireng after being inoculation. However, IR64 showed increasing OsNPR1 in 72h and did not change in 96h after inoculation. It indicated that OsNPR1 played important role in IR64 resistance against Xoo, but not in Cempo Ireng and Java14.

Abstract

A thorough study was conducted on foliar diseases of cowpea under widely cultivated cowpea producing areas of Nadia & Hooghly district of West Bengal. The areas were Mondouri, Jaguli Instructional farm, Muragacha, Rajberia, Chakdaha, Madanpur, Basantapur, Kalyani Incheck farm, Kalyani “C” block farm under Nadia district and Mogra under Hooghly district. The fixed plot survey was conducted during Pre-kharif, Kharif & Rabi season. Seven fungus has been isolated during survey period and these are- Alternaria alternata, Colletotrichum capsici, Corynespora cassicola, Fusarium ciceri, Rhizoctonia solani, Sclerotium rolfsii, Curvularialunata. Among these pathogens, Alternaria alternata, Colletotrichum capsici,Corynesporacassicola found to be most dominating pathogen during Pre-Kharif, Kharif & Rabi season respectively.Shifting of planting time was carried out for avoiding the plant pathogen at a particular growth stage of the crop. Five cultivars (Kashikanchan, Triguna, Manikanchan, KSP-170 &Arkagarima) were selected for the experimental trial for three different seasons against the main dominating pathogens. For Pre-Kharif planting of cowpea, the 1st week of March, for Kharif planting time, 1st week of June were established as most profitable. During Rabi season for planting of three varieties viz.Kashikanchan, Manikanchan& KSP-170, 4th week of November and for Triguna&Arka Garima, 2nd week of November were found most profitable due to least incidence of diseases and maximum yield.

Abstract

This study was designed to generate baseline data of the fish and seafood consumption pattern among major ethnics in urban, rural, and coastal regions of Peninsular Malaysia. A food frequency questionnaire was adapted and administered on healthy adult participants above 18 years. Fish and seafood is the prime animal protein source in Malaysian diet, comprising about one-third of total animal protein consumed. Average per capita fish and seafood consumption is 44.53kg/year, with higher levels observed in coastal (51.9kg/year) and rural (51.8kg/year) than urban areas (36.9kg/year). While the fish and seafood intake is relatively high, the total polyunsaturated fatty acids intake is borderline low. Despite cross- cultural and regional variations, there is a great overall preference for wild caught marine pelagic fishes. The demand has to be satisfied by imports, even after increasing local fishing effort. The data are beneficial for sustainability assessment and to inform policies for a sustainable food future

Abstract

Pineapple is a perishable agricultural products, therefore it needs an appropriate treatments at the postharvest stage. An appropriate treatment will contribute on maintaining the quality and prolong shelf life of the products. Recently, several efforts have been conducted to achieve the purposes. Moreover, appropriate treatments are still required for alternatives solution of pineapples producers. This study aims to determine the effect of the dipping on CaCl2 solution at various concentration on physical (mold incidence and mold severity), chemical (pH value) and sensory properties (color, texture, aroma, taste, and overall acceptance) of pineapple during storage. The dipping of the fruits were conducted at hot condition (50℃). The samples were MD-2 pineapple with two different classification of shell color (shell color 0 and shell color 2). The results showed that there was no significant effect of CaCl2 application treatment by dipping in hot water (50℃) on the parameters of pH value. The incidence and severity of mold were detected after 16th of storage on treated samples and the control. After storage for 40th days, the treated sample had better sensory properties, particularly on texture, color, and overall acceptance.

Abstract

The purpose of this research was to assess the efficiency of monosodium glutamate (MSG) as growth promoter in broiler chicken production. The study evaluated the effect of varying concentrations of MSG in the drinking water of broiler chickens on their growth performance, carcass characteristics and caecal Escherichia coli population. Ninety (90) chicks at 21 days of age were randomly selected and assigned to 5 treatment groups (0g/L, 2g/L, 3g/L, 4g/L and 5g/L) of MSG concentrations in a Completely Randomized Design (CRD) with 18 chicks per treatment and 6 chicks per replicate. MSG was administered in the drinking water. Feed and water were given ad-libitum and light provided 24 hours. The parameters measured were feed intake, weight gain, feed conversion efficiency, carcass dress weight, digestive organ traits and caecal Escherichia coli concentrations. Data collected were analysed using one-way ANOVA in GenStat (version 8). The results of the study showed an improvement (P<0.05) in feed intake and daily weight gain at 5g/L concentration and the highest (P<0.05) feed conversion efficiency was achieved at concentrations of 2 and 3g/L respectively. Carcass dress weight, liver and intestinal weights increased (P<0.05) at a concentration of 5g/L. However, those group of birds on 2g/L MSG concentration had the highest (P<0.05) heart weight and those of birds in the control had the highest (P<0.05) intestinal length. Escherichia coli concentration in the caeca reduced (P<0.05) as the concentration of MSG increased in the drinking water of birds. In conclusion, MSG supplementation in broiler chickens production could improve growth performance and reduce pathogenic microbes especially E. coli.
