QUALITY ASSESSMENT OF ORGANIC MENTIK SUSU AND NON-ORGANIC CIHERANG RICE IN CANDIPURO, SOUTH LAMPUNG

Combining text mining of social media data and conjoint approach to investigate consumer choices on organic food

The organic industry in Australia has grown from a few farmers into an established and complex system with thousands of producers. The participants in the system include producers, processors, marketers, retailers, exporters, consumers, certifiers, researchers and government institutions. Its boundary is marked by organic standards, certification and labelling. Producers are motivated to convert to organic farming, and consumers to purchase organic food, due to a mixture of tangible and intangible factors that influence their belief regarding the benefits they will obtain. However, for individual farmers, converting from conventional to organic production is often a challenging process because it requires a change in established farming practices. The burden of change is borne by farmers alone, even though many of the benefits of organic farming (such as health and environmental benefits) are enjoyed by wider society. This research examines the complex range of social, financial and environmental factors that influence farmers’ perceptions of the benefits and costs of converting to organic farming, using a probabilistic model. A similar model was also developed for illustrating consumers’ perceptions of the benefits and costs of purchasing organic food. The models aim to integrate the range and variability of farmer and consumer viewpoints surrounding the decision to convert, so that policy levers most likely to support the organic industry can be identified. Workshops, interviews, surveys and the findings of previous studies were used in this research to capture the key benefit and cost criteria considered by producers and consumers when deciding to adopt organic farming or food consumption. Bayesian Belief Networks (BBN) were used to integrate the criteria into Cost Benefit Analysis (CBA) models for comparing organic and conventional farming, and organic and nonorganic food. These models captured a variety of opinion from organic and conventional farmers, and organic and non-organic consumers, to produce a probabilistic assessment of the benefit-cost ratio of alternative farming and food consumption options. The BBN models were used to conduct sensitivity analysis to identify where policy interventions might bring about the greatest shift in the benefitcost ratio of organic farming and food consumption for producers and consumers. The research revealed that, for the certified organic farmers surveyed, intangible health and environmental benefits were greater motivations for converting to organic farming than tangible benefits such as profitability. Sensitivity analysis revealed that a shift in cost factors such as yield and price risks, certification costs, poor information availability and undeveloped market had a relatively large influence on the benefit-cost ratio associated with organic farming. Similar results from the consumer model indicated that intangible health and environmental benefits were strong motivations for frequent organic consumers to purchase organic food. However, the inconvenience of purchasing organic food and its price are still significant costs for them. The study identified some policy interventions that could have a relatively large influence on the organic sector. These were reducing yield and price risk of organic farming; streamlining the certification process to reduce costs and complexity; better provision of information on organic farming and best management practices; assisting the organic food distribution systems to improve market development and convenience of buying organic products; and increasing public awareness of the benefits of organic food production and consumption to improve the perceived value for money of organic food consumption. The BBN models developed in this study illustrate the complex mix of benefits and costs considered by farmers and consumers when choosing to enter that organic industry and offer an objective means for policy development in the industry to maintain the existing population of organic producers and consumers or attract new entrants to the organic industry.

Demand for local food in the US has significantly increased over the past decade. In an attempt to understand the drivers of this demand and how they have changed over time, we investigate the literature on organic and local foods over the past few decades. We focus our review on studies that allow comparison of characteristics now associated with both local and organic food. We summarize the major findings of these studies and their implications for understanding drivers of local food demand. Prior to the late 1990s, most studies failed to consider factors now associated with local food, and the few that included these factors found very little support for them. In many cases, the lines between local and organic were blurred. Coincident with the development of federal organic food standards, studies began to find comparatively more support for local food as distinct and separate from organic food. Our review uncovers a distinct turn in the demand for local and organic food. Before the federal organic standards, organic food was linked to small farms, animal welfare, deep sustainability, community support and many other factors that are not associated with most organic foods today. Based on our review, we argue that demand for local food arose largely in response to corporate co-optation of the organic food market and the arrival of ‘organic lite’. This important shift in consumer preferences away from organic and toward local food has broad implications for the environment and society. If these patterns of consumer preferences prove to be sustainable, producers, activists and others should be aware of the implications that these trends have for the food system at large.

This study aims to Determine the factors influencing the demand for organic Wakawondu rice in the Cooperative Bina Insan Cita Indonesia (BICI) in Baruga District, Kendari City. Wakawondu organic rice is essential to research because it is one of Southeast Sulawesi's leading commodities, and no research has discussed organic Wakawondu rice. This research was conducted from June to August 2022 at the BICI Cooperative Office. The data collected in this study was collected using primary data and secondary data. Preliminary data were obtained from interviews using questionnaires with BICI cooperative members as consumers and several buyers of organic rice they met. The method of determining the sample is accidental sampling, with the number of cooperative members as many as 30 people who happen to be at the research location. The analysis used Multiple Linear Regression analysis with the Ln method (Natural logarithm). The results showed that the factors that had a significant effect simultaneously on the demand for Wakawondu organic rice in the Bina Insan Cita Indonesia Cooperative, Baruga District, Kendari City, were the price of organic rice, the price of non-organic rice (rice head ), income, number of family dependents and consumer tastes.

Rice milling mode (brown and polished rice) creates a dilemma for organic brown rice (OBR) where the nexus is between consumer preference and nutritional properties. The appearance of rice is often considering an important attribute for consumers. Based on this, the present study examines the effect of nutritional information to the consumer preference of OBR. Forty university students have been recruited based on interest and availability. The subjects have been divided into two groups: A (nine males and 11 females) and B (seven males and 13 females), as per the order of information and non-information about the nutritional benefits of consuming OBR. Questionnaires to examine the quality concept of organic rice before and after the treatment have been prepared. ISO 13299, 2016 has been applied to establish a sensory profile. The single list attributes (taste, aroma, colour, and texture) have been used to examine panellist responses. Two varieties of long-grain organic rice have been prepared in the two-milling mode (brown and polished). This study reveals that the nutritional information of brown rice affects panellist responses on colour and texture. For the un-informed group B, colour and texture attributes were considered lower for brown rice compared with polished rice, while for the informed group A, there were no significant differences of these quality attributes between both rice types. The intervention of nutritional information seems to improve the lower brown rice attributes.

As an effort to overcome problems in rice cultivation system, it is necessary to use new technologies and innovations. This study aims to determine the physical and nutritional quality of grain and milled rice from 2 varieties of rice using several planting systems. The research was conducted using a Completely Randomized Design of factorial pattern, consisting of 2 factors with 3 replications. The factors were: a) Planting system (S1 = Cubic S2 = Double row 2: 1, and S3 = Twin seed) and b) Rice varieties (V1 = Ciherang; V2 = Inpari 10). The observation parameters include: physical quality of grain, rice milled quality, physical quality of rice and rice nutrition. The results showed that the cubic planting system produced a higher empty grains than the double row and twin seed planting system. The twin seed planting system, yielding lime green grains and yellow broken grains lower than other planting systems, both on rice varieties of Ciherang and Inpari 10. Grains from Ciherang variety had a thinner shell and a higher hardness level of rice compared to grain of Inpari 10 variety, resulting in higher milled rice and head rice, but lower in broken rice and rice groats contents. It can be concluded that: a) the physical quality of rice was not affected by the planting system, but it was significantly affected by the rice varieties; b) the planting system and rice varieties used in this study did not have significant effect on the nutritional quality of the rice produced.

Effect of various combinations of temperature during different phenological periods on indica rice yield and quality in the Yangtze River Basin in China

This study examined the preferences and development of Sitophilus oryzae on different organic and inorganic rice varieties by free-choice and no-choice tests. Feeding preference was assessed by the male and female adult present and the percentage of weight loss. The development was assessed by the numbers of eggs, larvae, pupae, and adults, the period of eggs, larvae, and pupae, the total development time, larval growth index, growth index, and biotic potential. The free-choice test showed that the number of male and female present and the percentage of weight loss were higher on inorganic rice than on organic rice of either the Shinta Nur or IR-64 variety. The no-choice test showed that the numbers of eggs, larvae, pupae, and adults were higher on inorganic rice than on both varieties of organic rice. The period of eggs, larvae, and pupae and the total development time were shorter on inorganic rice than on organic rice. The larval growth index, growth index, and biotic potential were higher on inorganic rice than on organic varieties. Organic rice had high levels of phenolic, amylose, and carbohydrates, but smaller seed size and lower protein levels and ash was preferred less compared with inorganic rice of both varieties.

Global organic food consumption has increased significantly in the last decade. Organic product agriculture is a one-of-a-kind technique that strikes a balance between environmental sustainability and consumer safety by developing a good client relationship with the end customer or consumer group. According to environmental studies, organic farming is less damaging to the environment than traditional agricultural methods. Recent studies show that customers who eat organic foods have lower pesticide exposure, which results in fewer human diseases. Organic food has more nutrients. However, the evidence to support this is lacking, and no well-designed human study has shown any direct health benefits or disease prevention benefits from consuming organically produced food. Furthermore, some researchers mention that for some types of plants, the nutrients in the case of conventional products were better. This study aims to identify the benefits of organic foods over conventional foods and consumers' beliefs about health and environmental benefits associated with organic foods. Secondary data for this research have been gathered from different international journals and the Internet, utilizing information from a variety of scholarly publications. The author addresses the present state of organic farming, as well as the benefits and disadvantages of consuming organic and conventional food,. The article has also investigated the effects of organic and conventional food production on both health and the environment.

Growing interest in organic agriculture has prompted numerous studies that compare various aspects of organic and conventionally produced foods. This paper provides a comprehensive evaluation of empirical studies comparing organic products and conventionally grown alternatives. The emphasis is on key organic consumer demand and marketing issues, including: (1) the implications of an economic definition of organically grown food for consumer demand; (2) attributes that shoppers consider most when comparing organic with conventionally grown products; (3) level and characteristics of consumer knowledge and awareness about organic food; (4) assessment methods and characteristics of organic consumer attitudes and preferences; (5) size of price premium and characteristics of consumers’ willingness-to-pay for organic products; and (6) profile of organic consumers. Overall, although there is some knowledge and awareness about organic products, consumers are not consistent in their interpretation of what is organic. Secondly, while consumers typically understand the broad issues about organic foods, many tend not to understand the complexities and niceties of organic farming practices and organic food quality attributes. Uncertainty regarding the true attributes of organic, and skepticism about organic labels, part of which stems from reported cases of (inadvertent) mislabeling, and product misrepresentation, and partly because of nonuniform organic standards and certification procedures, may hold some consumers back from purchasing organic. Thirdly, concern for human health and safety, which is a key factor that influences consumer preference for organic food, is consistent with observed deterioration in human health over time and, therefore, motivates consumers to buy organic food as insurance and/or investment in health. Fourthly, the proportion of consumers who are willing to pay a price premium for organic food decreases with premium level. On the other hand, premiums tend to increase with (combinations of) preferred attributes. In addition, demand tends to depend more on the price differential with respect to conventionally grown products, than on actual price. In contrast to sensitivity of demand to changes in price, income elasticity of demand for organic foods is generally small. Finally, it is important for policy analysts and researchers to note that organic fresh fruits and vegetables currently dominate the organic consumer's food basket. Furthermore, it is not clear whether frequent buyers consider particular organic products (e.g., organic meat) as normal goods, or if consumers consider such products as luxury goods.

Organically farmed rice is believed to be healthier, safer, and eco-friendlier than its conventionally farmed counterparts and sells for a premium price in global markets. Deliberate mislabeling of organic rice has become a critical consumer concern in China and elsewhere, and there is an increased risk of buying fraudulent organic rice in the market place. In this study, stable isotopic and multielemental analysis combined with chemometrics was used to differentiate organically farmed rice from green and conventional rice in a 4-year experimental field trial from 2014 to 2017. A total of 108 rice samples and their associated soils were collected during the study from three farming (fertilization) systems to investigate whether there are long-term changes in the rice farming classification accuracy from climate effects. Stable carbon and nitrogen isotopic ratios (i.e., δ13C and δ15N) and 27 elemental contents (e.g., Na, K, Ca, Fe, and Zn) of rice and soil samples were determined and then evaluated using statistical analysis [i.e., one-way analysis of variance, multivariable correlation analysis, and modeling of partial least-squares discriminant analysis]. Although δ15N values can be an effective indicator for organic rice authentication during one crop rotation, both δ13C and δ15N values of rice were easily affected by rice cultivar and interannual soil fertilization and localized agroclimatic variations. These two isotopes were not able to separate organic rice from green and conventional rice accurately. Elemental contents of green and conventional rice (especially K and Ca) were found at higher levels due to the abundant application of synthetic fertilizers (e.g., KNO3, KH2PO4, and CaHPO4), unlike organically farmed rice, which primarily used animal manure and composts. Partial least-squares discriminant analysis modeling combined isotopic and elemental signatures to correctly differentiate organic rice from green and conventional counterparts, with an accuracy up to 100% over the 4-year study. Therefore, this multi-isotope and -element strategy proposes a more rigorous, alternative tool to combat fraudulent mislabeling of organic rice, increasing the trust of organically labeled rice products and supporting the integrity of the organic sector worldwide.

Factors influencing participation in collective marketing through organic rice farmer groups in northeast Thailand

The production and consumption of organic rice in Indonesia continue to increase along with the growing public awareness of the importance of healthy eating habits and environmental conservation efforts. Consumers in Central Java and Yogyakarta increasingly favor organic rice, prioritizing health and product quality. This has led to increased demand and can also motivate farmers to increase organic rice production to meet the ever-growing market needs. This study analyzes the market dynamics and consumer preferences for organic rice in Central Java and Yogyakarta. The research employed a quantitative descriptive approach, utilizing the 4P marketing mix (product, price, place, promotion) and a Likert scale to measure consumer preferences. Sampling was conducted through proportional stratified random sampling from five regencies, with 310 respondents. The results show that promotion is the most significant factor influencing consumer purchasing decisions, with a relative importance of 30.289%. The primary factors driving consumer preferences for organic rice are health benefits and product quality. Although organic rice is priced higher than conventional rice, consumers tend to choose it due to its health and sustainability benefits. However, uneven distribution of organic rice and price fluctuations caused by high production costs and climate factors pose major challenges. The study suggests more intensive promotional strategies, improved market accessibility, and subsidy policies to support farmers’ production costs. By understanding market dynamics and consumer preferences, this research provides critical insights for stakeholders to design more effective policies and marketing strategies while supporting sustainable agriculture in Indonesia.

IntroductionThe threat of climate warming to global rice production has been widely addressed, but little is known about its influence on the quality of rice grains.MethodsA free-air temperature increase (FATI) facility with two widely-planted high-quality cultivars was used to explore the impact of warming on the grain quality of early rice in subtropical China over 3 consecutive years.ResultsCompared with the control, FATI increased diurnal canopy temperature by 1.5°, and thus, rice growth duration was shortened by 4.0 d under warming. We found that warming significantly reduced both the milled rice and head rice rates relative to the control, thereby leading to a decrease in the milled rice and head rice yield by 3.9 and 8.3%, respectively. The chalky grain rate and chalkiness were increased by 19.1 and 22.2% under warming compared with the control, respectively. The content of protein, essential amino acids, and non-essential amino acids were increased by 4.1, 5.4, and 4.9% under warming, respectively. Warming reduced the amylose content and setback by 2.0 and 47.5% but increasing peak viscosity, trough viscosity, breakdown, and final viscosity by 9.5, 13.6, 5.7, and 6.0%, respectively.ConclusionOur results suggest that the deteriorated milling and appearance quality induced by warming may be an upcoming challenge for high-quality early rice production in the future.
