Utilization of Data Mining Techniques in National Food Security during the Covid-19 Pandemic in Indonesia

Abstract

The aim of the research is to map clusters on Indonesia’s national food security during the Covid-19 Pandemic. Where food security is a condition for the fulfillment of food for the state up to individuals, which is reflected in the availability of sufficient food, both in quantity and quality, safe, diverse, nutritious, equitable, and affordable and does not conflict with the religion, beliefs and culture of the community, to be able to live a healthy, active, and productive life in a sustainable manner. The data source used is secondary data from the Central Statistics Agency (abbreviated BPS). The data consists of monthly per capita expenditure in urban and rural areas by province and group of goods (rupiah) consisting of 33 data records (2011-2018). The group of goods used is expenditures used for food costs. The data mining method used is k-medoids which are part of the clustering. Cluster mapping uses 2 labels namely C1: labels with high food security and C2: labels with low food security. The results of the k-medoids method calculation concluded that 19 provinces were in C1 cluster and 14 provinces were in C2 cluster. From these results it is stated that 42% of Indonesia still has low food security as evidenced by the fulfillment of higher food needs than non-food. These regions are West Sumatra, Riau, Bangka Belitung Islands, Riau islands, DKI Jakarta, West Java, Banten, Bali, Central Kalimantan, South Borneo, East Kalimantan, North Sulawesi, West Papua and Papua.

Market basket analysis of administrative patterns data of consumer purchases using data mining technology

“…Data mining is the process of obtaining data from databases using algorithms and techniques that include statistics, mechanical study and databases, in which data extraction in a large variety of databases gives you a joy in the form of knowledge [11,[15][16][17]. Important matters concerning the mining of data are: a.…”

“…Furthermore, the application of data mining can perform data analysis of item sales transaction data, which produces several association rules in customer purchasing patterns in supermarkets, which is why it is being implemented [7][8][9]. The process of searching for hidden patterns of data for each transaction whose previously unknown type of data is stored in databases, data warehouses, or other information storage media is referred to as data mining [10][11][12][13]. Several data mining methods are frequently used, including the Apriori Algorithm, which determines the itemset of book loan transactions, which are then grouped into itemset1 [14].…”

Battling COVID-19 using machine learning: A review

“…After certain iterations, we get medoids which successfully cluster the dataset. Deployment of Data Mining Techniques which included k-medoids algorithm in National Food Security in Indonesia during the COVID-19 pandemic was discussed in (Elsi et al, 2020).…”

Forecast Analysis of Gross Regional Domestic Product based on the Linear Regression Algorithm Technique

“…There is a need to develop an extraction approach which can inform more knowledge of the regional economy [1]. Another mechanism that could be employed is data mining [2]. Data mining is an extraction of hidden information from data warehouses [3].…”
