Halal Food Prediction Using the Similarity Graph Algorithms
Full text linkOnly halal food is food allowed by Islamic sharia. In contrast, haram food is forbidden, for example, alcohol, pork, blood, carrion, and meat not slaughtered according to sharia regulations. In Indonesia, halal certificates are issued by the Halal Product Guarantee Agency (BPJPH) based on Article 39 of Law Number 33/2014 concerning Halal Product Guarantees. A halal certificate guarantees that food is composed of halal ingredients. However, many halal food products do not have a halal certificate. Therefore, it is useful to estimate the halal status of food products that have not been certified. In this work, we attempted to predict the halal status of food using several graph similarity algorithms. We acquired product data from the KlikIndomaret website, which contained the food product name, the composition of the food product, and the manufacturer. Then, we crawled the halal food database on the Halal MUI website. Both datasets were merged into a single dataset based on the product names. Then, similarity algorithms such as Jaccard Similarity, Approximate Nearest Neighbor, Adamic Adar and Preferential Attachment were performed on the products in the dataset. The accuracy of each algorithm evaluated by F-measure
Bringing together Stakeholders’ Interaction and Economic Modelling: Recent Experiences in Designing Research and Agricultural Policy
Full text linkPolicies are becoming intensively interrelated while increasing numbers of societal groups and stakeholders are affected. At the same time, current and future challenges require improved capacity in terms of models, their linkages or redesigns to deliver forward-looking insights on policies. Different stakeholder workshops have recently been carried out in the context of two scenario studies to support these activities, including stocktaking, inputs for narratives, validation of the outcomes, acceptance of analysis and drafting future research agendas. This paper describes the approaches applied in both projects, shortly presents their results and findings to finally draw some general conclusions
Agricultural Cooperative Development and Institutional Change: Swedish Examples from 1990 to 2020
Full text linkThis paper shows how cooperatives’ changing organizational structures can be explained by the Theory of Institutional Change. When a cooperative’s decision makers receive exogenous signals, endogenous processes concerning organizational adaptations start. Radical changes are met with resistance, such as the conver sion of a traditional cooperative into an entrepreneurial cooperative (where members have individual ownership) or a farmer-controlled business (external investors participate in ownership and governance). Cooperative memberships and leaderships may have change agents who advocate for new institutions while gatekeepers try to resist them.The development of Swedish agricultural cooperatives from 1990 until 2020 illustrates this theoretical reasoning
Mindsets in Intra-familial Farm Transfer: Successful Successor and Predecessor Prototypes
Full text linkThis paper investigates mindsets in the context of family farm succession. Using a grounded theory approach, interviews and group discussions were analyzed. Results based on both data sets present prototypical mindsets of successful predecessors and successors. The mindset construct, which has been developed for this study, was expanded with stakeholders, information flows, and time, according to the results of this study. The findings provide insights into information processing in intra-familial farm succession and the mindsets of successful predecessors and successors. The mindset approach offers a supplementary and valuable perspective on the succession process. It can contribute to early action taking of farming families or consultants
Price Dependence in the Supply Chain on the Mushroom Market in Canada
Full text linkThe aim of this dissertation is to assess the dependence in the mushroom supply chain in Canada. Statistical research has proven that there exists vertical transmission of prices between those of the producers, wholesalers and retailers. According to the results, retail prices, which are definitely higher than prices at other distribution levels, did not exhibit a statistically significant relationship with other prices. At this stage of distribution, the level of prices depended mainly on values in previous periods at the same stage of sales. At the stage of wholesale trade and the producer’s level, relations in price formation were demonstrated. The autoregressive distributed lag model (ARDL) therefore indicates the occurrence of asymmetry in the transmission of mushroom prices between trade levels. The results suggest that retail prices paid by the final consumers depend on retail prices from previous months. Wholesale prices seem to be significantly affected by both producer prices and retail prices. At the same time, it was pointed out that producer prices depend on prices from previous periods and as well as on those applied at the wholesale level

Prospective cultivation Area of Field Peas used in Animal Meat Substitutes in the EU
Full text linkMeat alternatives from leguminous raw materials are expected to play an increasing role in human nutrition.The US Company Beyond Meat entered the EU retail market in the UK, the Netherlands and Germany with apea-based vegan burger patty in 2019 which is seen as accelerating the trend towards plant-based meatalternatives in the EU. Pea protein isolate is the protein basis of the Beyond Meat burger patty. The rawmaterial basis for the protein isolate can be assumed to be peas from the northern states of the US and fromCanada. Additional global cultivation areas and additional general cultivation potential for peas are forecastedfor the short to medium term. European peas may become increasingly used as raw materials in the future ifthe expected market growth evolves with a regional origin of the raw materials. This would result in additionalsales potential for EU legume producers with growing cultivation areas. The aim of the present study is toestimate the prospective area of peas for pea-based meat alternatives in the EU within a simple modelcalculation. Various data sources were used to estimate the cultivation potential. In addition, plausibleassumptions were made in case of unavailable data. To estimate future consumption shares, an expert panelwas interviewed as part of the European joint project LegValue. Based on per capita consumption of animalmeat, consumption volumes of pea-based meat alternatives were estimated. With a consumption share of 2 %for pea-based meat alternatives in the EU, the effects on the production volume and pea cultivation arearemain relatively small. With an increased consumption share of pea-based meat alternatives of 12.5 % the peacultivation area would rise to almost 100 % compared to the current cultivated area. By the third scenario witha consumption of 40 % pea-based meat, the cultivated area would triple. However, the additional share of thepea cultivation area in the total arable area in the EU would be only a small additional increase. Thus, increasedpea cultivation would only have minor effects on competition for agricultural land. If pea-meat replaced animalmeat, land used for animal feed production would become available
Modeling of Salt Supply Chains to Achieve Competitive Salt Prices
Full text linkTo achieve the self-sufficiency of salt, prices need to be considered. This study develops a dynamic simulation model of salt supply chains to analyze the significant factors affecting prices from upstream to Indonesia's downstream levels. A set of dynamic simulation models is developed to achieve competitive prices using system dynamics. Furthermore, the system dynamics framework is utilized because it can model non-linear behavior between variables with a significant contribution to the system. Based on the simulation results, local and imported salt prices may compete by implementing land integration systems. This system is likely to reduce production costs and increase farmers' revenues to IDR 61,211,892 at the end of the simulation in 2035
Do Customer Profitability Accounting and Analyses Provide Managers with new Decision Support? Evidence from Norwegian Fish Exporters
Full text linkThis paper has two purposes: (1) to study the relationships between subject ive and objective (cost-based) measures of customer profitability, and (2) to study managers’ collective cognitions of their customers’ profitability. Empiricaldata have been collected from four Norwegian fish exporters: (1) managers’ a priori subjective judgments of the profitability of customers, and (2) customer profitability accounts (not available earlier). This industry has a very high level of directly traceable costs (98.5 per cent) implying very low uncertainties in the measures of customer profitability. Associations between subjective and objective measures of customer profitability measures are weak both regarding absolute and relative customer results. Managers have common perceptions with respect to customer profitability, however, not in accordance with the customer profitability accounts (CPA). Neither education nor experience can compensate for insufficient or missing customer accounts that provide reliableprofitability figures. Intuition may function best when “cornerstones” based on rational working methods are available for the decision makers. Thus, CPA provide managers with new decision support . The paper emphasizespractical implications regarding customer profitability accounting and management decisions
Management of Disease-triggered Shocks in Complex Value Chains: An Ex Ante Analysis of Market Effects of HPAI Control in the Dutch Egg Supply Chain
Full text linkExternal shocks, such as disease occurrence, can be very disruptive in complex food producing value chains. To analyze this, a vertically linked dynamic partial equilibrium model was used to analyze market effects of outbreaks of Highly Pathogenic Avian Influenza (HPAI) in The Netherlands. Various shock inducing scenarios were analyzed, e.g control strategy, demand shocks and trade bans. The results showed that in densely populated poultry areas (1) market effects usually outweigh direct control costs, (2) vaccination could help mitigating total disease costs,particularly if (3) channeling to industrial processing is included. Moreover, large, and in some cases opposing differences in market effects between the various stakeholders could be observed. The result suggest a number ofimportant policy factors that should be considered in HPAI control, e.g. the poultry density, the production structure and differentiation of stakeholders, the dependency on international trade and the potential capacity ofindustrial processing of eggs. General implications for other food producing value chains are discussed
