The participation of household prosumers in wholesale electricity markets is very limited, considering the minimum participation limit imposed by most market participation rules. The generation capacity of households has been increasing since the installation of distributed generation from renewable sources in their facilities brings advantages for themselves and the system. Due to the growth of self-consumption, network operators have been putting aside the purchase of electricity from households, and there has been a reduction in the price of these transactions. This paper proposes an innovative model that uses the aggregation of households to reach the minimum limits of electricity volume needed to participate in the wholesale market. In this way, the Aggregator represents the community of households in market sales and purchases. An electricity transactions portfolio optimization model is proposed to enable the Aggregator reaching the decisions on which markets to participate to maximize the market negotiation outcomes, considering the day-ahead market, intra-day market, and retail market. A case study is presented, considering the Iberian wholesale electricity market and the Portuguese retail market. A community of 50 prosumers equipped with photovoltaic generators and individual storage systems is used to carry out the experiments. A cost reduction of 6–11% is achieved when the community of households buys and sells electricity in the wholesale market through the Aggregator.

Aquaculture Industry

Abstract Aquaculture is currently one of the most rapidly growing food production industries in the world. The increasing global importance for this industry stems primarily from the fact that it is reducing the gap between the supply and demand for fish products. Commercial aquaculture contributes significantly to the economies of many countries since high-value fish species are a major source of foreign exchange. This review looks at the aquaculture industry, the issues raised by the production of fish through aquaculture for food security, the sustainability of the practice to agriculture, what the future holds for the industry in the next 10-20 years, and why there is a need to have available analytical procedures to regulate the safe use of chemicals and veterinary drugs in aquaculture.

Marginal Price

In contemporary energy markets, the Retailer acts as the intermediate between the generation and demand sectors. The scope of the Retailer is to maximize its profits by selecting the appropriate procurement mechanism and selling price to the consumers. The wholesale market operation influences the profits since the mix of generation plants determines the system marginal price (SMP). In the related literature, the SMP is treated as a stochastic variable, and the wholesale market conditions are not taken into account. The present paper presents a novel methodology that aims at connecting the wholesale and retail market operations from a Retailer’s perspective. A wholesale market clearing problem is formulated and solved. The scope is to examine how different photovoltaics (PV) penetration levels in the generation side influences the profits of the Retailer and the selling prices to the consumers. The resulting SMPs are used as inputs in a retailer profit maximization problem. This approach allows the Retailer to minimize economic risks and maximize profits. The results indicate that different PV implementation levels on the generation side highly influences the profits and the selling prices.

The increasing demand of vegetal biomass for biogas production is causing competition with food production. To reduce this problem and to provide new opportunities it is necessary to take into consideration different kinds of vegetable biomass that are more sustainable. Grass from the maintenance of non-cultivated areas such as riverbanks has not yet been fully studied as a potential biomass for biogas production. Although grass has lower methane potential, it could be interesting because it does not compete with food production. However, there is a lack of appropriate technologies and working system adapted to these areas. In this paper, different systems that could be available for the mowing and harvesting of grass along riverbanks have been preliminarily assessed through the evaluation of the field capacity, labour requirement, economic and energy aspects. The splitting of the cutting and harvesting phases into operations with different machinery seems to be the best system for handling this biomass. However, these solutions have to take into consideration the presence of obstacles or accessibility problems in the harvesting areas that could limit the operational feasibility and subsequent correct sizing.

Of 629 fresh fish (sixty-five species) and forty-two samples of fish-washings obtained from a fish-market in Colombo, and investigated bacteriologically for the presence of Salmonella, thirty-nine fish (twenty-four species) and five samples of washings were found to be harbouring the organisms.Of fifteen salmonella types found, all except Salm. chittagong and Salm. oranienberg had been previously isolated from human and animal sources in Ceylon.The presence of Salmonella in the intestines of fresh fish examined suggested that the organisms had entered the live fish, whilst their isolation from the gills and fish-washings was evidence that the fish could have been contaminated post-mortem.The significance of these findings in relation to hazard to health is discussed.

Study Results

The fisheries sector is one of the agricultural sub-sectors that has a role in providing food for the people of Indonesia. Consumers have behavior in purchasing fish in meeting their needs or desires to obtain a product. This study aims to analyze consumer preferences for the type of fish and the order of attributes. The method used in this research is a case study. The research location was carried out at the Muara Baru Modern Fish Market (PIM) DKI Jakarta. The data used are primary data and secondary data. The primary data collection technique used accidental sampling with a sample of 100 respondents while the secondary data were obtained from Perum Perikanan Indonesia as the manager of the Muara Baru Modern Fish Market, the Library, the Central Statistics Agency (BPS) DKI Jakarta, the National Statistics Agency (BPS). Consumer preference analysis used attitude measurement analysis measured by Chi-square and based on rank orders analysis to determine the order of attribute importance. Based on the study results, it was shown that all the attributes observed in this study were significantly different at the 95% confidence level. In contrast, the analysis of the level of importance of the attributes showed that the priority of consumers' interests in fish in the Muara Baru Modern Fish Market (PIM) was price, freshness, cleanliness, texture, and fish scent.

Nowadays, the use of formalin as a preservative in fish is often found in society. Besides, the consumption of fresh fish products containing heavy metals will potentially cause various diseases both short and long-term. The aims of this study were to assess the knowledge of society about formalin, detect the presence of formalin, and analyze the heavy metal content of Pb, Cd, and Hg in Yellow striped fish, Tuna and Mackerel fish. The qualitative detection was done using Schiff reagents, while the quantitative detection was done by using the Spectrophotometry based on the reaction of formaldehyde and Nash reagents. The results showed that 50 percent of society did not know about the use of formaldehyde and its characteristics in fish. The Qualitative testing on 9 samples found that 2 samples contained positive formalin, while 7 samples were negative. The quantitative test showed that the highest formalin content was found in Tuna and Mackerel fish with concentration of 3.36 ppm, and 1.26 ppm, respectively. Also, mercury was found as the highest concentration in fish roughly 1 to 1.60 ppm for those samples from three different markets.                                                                                                                                                 Keywords: formalin, heavy metal, fresh fish, market, Kupang city

The relationship between fishermen and fisheries (sea) is very close, the dependence of fishermen on fish as a source of livelihood makes fish the main sector in coastal areas. Fish resources can be utilized for the greatest prosperity and welfare of the people, however the utilization of these fish resources must be carried out in a sustainable and responsible manner. This means that the utilization of fish resources must be carried out in a balanced manner and taking into account their carrying capacity and the ability of the resources to recover. During the current Covid 19 pandemic, fishermen's “fishing” activities in the Serang District of Banten Province have been disrupted, due to limited supply of fuel due to the PSBB (Large-Scale Social Restrictions), the catch is not selling well in the market or the reduced end (consumers) to the fish market . Indonesia since 2016 has had Law Number 7 of 2016 concerning the Protection and Empowerment of Fishermen, Fish Farmers and Salt Farmers, however the implementing regulations have not yet existed, so it is difficult to implement, moreover this regulation is urgently needed during a pandemic civid 19 this time.This writing is the result of an independent internal research that has been completed using legal (juridical) normative and empirical research methods (as supporting data and research arguments) carried out in the coastal area of Serang Regency.

The direct contribution of agriculture sector to national economy is reflected by its share in total GDP, its foreign exchange earnings, and its role in supplying savings and labor to other sectors. However the contribution has declined in the last two decades. The traditional market structure of agriculture leads to exploitation of poor and illiterate farmers by intermediaries. ITC E-chaupal supply chain model is a strategic agribusiness approach to free this vulnerable section from the clutches of intermediaries by making them aware about market and other such information necessary for better farming. The success of E-choupal has signaled a new era in Indian agro-sector and is a win-win partnership between the farmers and the organization.
