ABSTRACT
Broiler chicken eggs are one of the main and strategic foods for the people of Indonesia and contribute to regional and national inflation. Broiler egg production in Indonesia differs between regions. Areas with a surplus of eggs tend to have lower prices than areas with a deficit. This research is to measure the transmission of broiler egg prices between markets in surplus and deficit areas, using weekly price time series data for the period January 2018-December 2021. Areas of surplus broiler eggs, East Java Province (the highest broiler egg production in Indonesia) which become one of the main suppliers to the Province of East Nusa Tenggara as a deficit area. Using the Johannsen cointegration test it is found that there is no cointegration or there is no relationship between the surplus and deficit regions in the long term but not in the short term. Factors of marketing infrastructure, market information systems, and geographical conditions can be obstacles to the absence of cointegration. The VAR (Vector Auto-Regressive) Vector Error Correction model (VECM) test, found that price transmission occurred between surplus and deficit areas, meaning that between the two regions, there was market integration prior to Covid. The transmission has weakened, and due to the Covid situation, there have been restrictions on the movement of people and goods. The government and other market players need to study the response of the broiler egg market, in the short and long term so that market players can make the right policies.
ABSTRACT
Conjunctivitis is one of the common and contagious ocular diseases which affects the conjunctiva of the human eye. Both the bacterial and viral types of it can be treated with eye drops and other medicines. It is important to diagnose the disease at its early stage to realise the connection between it and other diseases, especially COVID-19. Mobile applications like iConDet is such a solution that performs well for the initial screening of Conjunctivitis. In this work, we present with iConDet2 which provides an advanced solution than the earlier version of it. It is faster with a higher accuracy level (95%) than the previously released iConDet. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
ABSTRACT
An efficient commodity market creates a price relationship between two or more markets. This study provides an overview of the behavior of premium granulated sugar prices and the price relationship between market levels. Time series data for the period January 2018-March 2022, are used in this study. Graphical trend analysis;and cointegration analysis with Vector Autoregression (VAR) approach to find research objectives. The research found that the price behavior of premium quality granulated sugar in the traditional market and the modern market is more dynamic than the price at the wholesaler level. The highest price spike occurred in the early period of covid-19, and several months later it returned to stability. Price behavior in traditional markets does not follow movements at other market levels simultaneously but takes some time to reach equilibrium. There is a long-term rionship (cointegration) between prices at the level of traditional markets, modern markets, and wholesalers, which contribute to the balance in the market. Market players need to take a strategic role in maintaining price balance at every level of the market in order to create an efficient and fair market.
ABSTRACT
Conjunctivitis is a common ocular disease characterized by infection or swelling in the outer membrane of human eye. This contagious ocular disease could be controlled and well treated by medicines depending upon it’s category. To realize the connection between Conjunctivitis and other viral diseases, even for COVID-19, timely detection plays an important role. In this study, we have designed a mobile healthcare application (iConDet) through which initial level of Conjunctivitis detection is possible. Deep learning techniques have been used upon the Conjunctivitis dataset prepared by us in support of the claim and to achieve the desired accuracy of 84%. © 2021, Springer Nature Switzerland AG.
ABSTRACT
Horticultural food commodities such as shallots are a staple and strategic commodity in Indonesia which is affected by the covid-19 pandemic situation. This study is to answer the pattern of price movements and disparities, as well as the level of fluctuations in the price of shallots due to the covid-19 pandemic in traditional markets in Kupang and Surabaya. Kupang NTT as the recipient of shallots supplies from Surabaya, East Java. Using time-series data of the shallot prices for the period of June 2016 - March 2020 to see disparities and fluctuations, which analyzed using graphics and coefficient of variation (CV). The results of the analysis found that the disparity and fluctuations of the price of shallots between the periods of June 2016 - March 2020, showed a movement that continues to increase, but with a fluctuating increase. Price disparity and fluctuation in Kupang is higher than in Surabaya. This difference is in addition to the seasonal factor also because Surabaya is one of the main suppliers of shallots to Kupang. So that the prices sensitively will rise if there is a disruption in distribution (supply). This seems clear when the initial enactment of social distancing and panic buying took place. Market operations and policies to improve efficiency in the distribution of trade in goods need attention.
