Examining Heterogeneity Structured on a Large Data Volume with Minimal Incompleteness

While Big Data analytics can provide a variety of benefits, processing heterogeneous data comes with its own set of limitations. A transaction pattern must be studied independently while working with Bitcoin data, this study examines twitter data related to Bitcoin and investigate communications pattern on bitcoin transactional tweet. Using the hashtags #Bitcoin or #BTC on Twitter, a vast amount of data was gathered, which was mined to uncover a pattern that everyone either (speculators, teaches, or the stakeholders) uses on Twitter to discuss Bitcoin transactions. This aim is to determine the direction of Bitcoin transaction tweets based on historical data. As a result, this research proposes using Big Data analytics to track Bitcoin transaction communications in tweets in order to discover a pattern. Hadoop platform MapReduce was used. The finding indicate that In the map step of the procedure, Hadoop's tokenize the dataset and parse them to the mapper where thirteen patterns were established and reduced to three patterns using the attributes previously stored data in the Hadoop context, one of which is the Emoji data that was left out in previous research discussions, but the text is only one piece of the puzzle on bitcoin transaction interaction, and the key part of it is “No certainty, only possibilities” in Bitcoin transactions

PRODUCT BUNDLING APPLICATION TO SUPPORT IMPLEMENTATION OF ASSOCIATION RULE MINING USING FP-GROWTH

Online media has been proven to gave good impact especially in the business field, for opening and widen access to people and society, and so giving more opportunity to any business broader and easy access through electronic commerce (e-commerce).

Indonesian MSME E-Commerce among the Covid-19 Pandemic

Objective - This study aims to find out (1) how the e-commerce utilization model before and during the pandemic, (2) the influence of the level of education on the tendency to use e-commerce (3) the marketing media used before and after the Covid-19 pandemic, and ( 4) the average income of MSME actors before and after the Covid-19 pandemic. The research method used is an explanative quantitative method, using a questionnaire, examining theories and policies related to Covid-19 and the application of e-commerce. Methodology/Technique – This study used a sample of 75 MSME actors and found that there was a significant increase in the use of e-commerce by Indonesian MSME actors during the Covid-19 pandemic. The use of online media in economic activities during the pandemic increased from 21.33% to 54.67%. Meanwhile, the education level of the MSME actors did not influence the decision to change the transaction pattern from offline to online with r score of 0.132. Finding – This means that this pandemic has changed the way of transactions in economic activity to its roots no matter how high the education level of the MSME actors is. The income of MSME actors has actually dropped dramatically during the pandemic, especially the period when the government implemented the Large-Scale Social Restrictions (PSBB) policy.

HUBUNGAN SPASIAL TRANSAKSI TANAH DENGAN PERKEMBANGAN WILAYAH DI KABUPATEN CIREBON, JAWA BARAT

The big potential of Cirebon Regency with good transportation access and demography bonus is able to promote its regional development. Not all of the potential has been optimized to invite investment in Cirebon Regency. One of the causes is some of the lands haven't been registered, so that obstructs investment that requires land. We explore the spatial relationship between the regional development level and land transaction pattern. We calculate the entropy diversification index to see the level of regional development. We also interpolate the land transaction to see the spatial pattern. The natural neighbor interpolation method was used to show spatial patterns of land transactions. Then, we overlay the map of the entropy index and land transaction pattern map to see the relationship spatially. Land transactions in Cirebon Regency gathered in a very developed and developing region. Districts of Palimanan, Depok, Plumbon, Weru, and Plered that are categorized very developed have more quantity of transactions and land transaction value than the undeveloped area. Pasaleman district has Kecamatan Depok, has the smallest entropy index, and categorized as undeveloped has a lower number and value of land transactions. We found a similar spatial pattern between the regional level of development and land transaction interpolation.

Make or buy: the case of harvesting mechanization in coffee crop in Brazil

This paper investigates the make-or-buy choice on the harvesting mechanization transaction in Brazilian coffee production. It empirically tests this organization choice following the transaction attributes of asset specificity, uncertainty and path dependence. Using a two-stage probit model conditioned by credit availability in a sample of 105 coffee growers in Brazil, our study evidences that the governance decision follows the efficient alignment argument of the Transaction Cost Economics. The research contributes to the understanding of institutional arrangements in place at coffee grower perspective. An additional descriptive field investigation presented the existence of three different types of arrangement as a solution for coffee harvesting mechanization: total vertical integration (make), outsourcing contracts (buy) and tapped vertical integration. Those results demonstrate a shift from a spot transaction pattern to more sophisticated contractual tools. We present managerial implications by illustrating the determinants of each decision, either make or buy, in the harvesting mechanization transaction in coffee production which can provide support to efficient strategies elaboration by farmers or service providers.
