A 5G RURAL, REMOTE, AND DIFFICULT AREAS HOPE: A REVIEW
Get PDFThe 5G cellular networks are “urban” areas technology in nature, extensively deployed where the user’s density is high to provide very high data rates, coupled with extremely low delays and dealing with very high mobility of users. On the contrary, one-third of people experience a lack of mobile broadband connectivity living in rural zones. These mobile broadband lacks recognized as the main barriers impairing the Sustainable Developing Goals (SDGs) defined by the United Nations. Those that are not currently covered will be unlikely to be covered also soon, as the network operators are not keen to invest in such zones, because of potentially low revenues. While it is confirmed that 5G would meet stringent requirements in urban zones, rural areas still suffer from almost inexistent MBB (Mobile Broadband) coverage, especially in the developing world. The big deal of isolated rural areas, which are sparsely inhabited by low-income populations, is that the classical access using traditional backhaul technologies is a bad solution for operators since it does not ensure a good ROI (Return of Investment)
HOW MACHINE LEARNING METHOD PERFORMANCE FOR IMBALANCED DATA : Case Study: Classification of Working Status of Banten Province
Get PDFThis study will examine the application of several classification methods to machine learning models by taking into account the case of imbalanced data. The research was conducted on a case study of classification modeling for working status in Banten Province in 2020. The data used comes from the National Labor Force Survey, Statistics Indonesia. The machine learning methods used are Classification and Regression Tree (CART), Naïve Bayes, Random Forest, Rotation Forest, Support Vector Machine (SVM), Neural Network Analysis, One Rule (OneR), and Boosting. Classification modeling using resample techniques in cases of imbalanced data and large data sets is proven to improve classification accuracy, especially for minority classes, which can be seen from the sensitivity and specificity values that are more balanced than the original data (without treatment). Furthermore, the eight classification models tested shows that the Boost model provides the best performance based on the highest sensitivity, specificity, G-mean, and kappa coefficient values. The most important/most influential variables in the classification of working status are marital status, education, and age

RAW DATA SECURITY BY USING ELGAMAL AND SHA 256 PUBLIC KEY ALGORITHM
Get PDFThe development of information technology has grown exponentially and various of data collections and its method has been obtained. In the era of big data, data has now become an asset that held important values, while in the implementation of data delivery, it clearly is not always safe. One of the method to secure data delivery is data encryption using Cryptography. Cryptography provides an encryption service to secure data delivery by transforming it to random values so that it can no longer be read. The goal in this study was to produce an application that could be used to encrypt data, using ElGamal's cryptography method and hash checking using the SHA256 algorithm. After encryption, to ensure the encrypted data is still the original data without any changes or manipulation by unauthorized 3rd party then done by checking the hash generated using SHA256 algorithm. The data used in this study was a sample of raw data from the ATPWTP survey (ability to pay and willing to pay) conducted by the BPS Cirebon (Central Statistics) in 2019 and the data was in the form of Excel and txt files. The encryption process resulted in a cipher larger than the plaintext and takes longer for the data encryption process than during the data cipher decryption process
