Abstract

Di pedesaan, biasanya sekolah negeri begitu banyak diminati karena biaya pendidikan yang relatif terjangkau. Namun pada kenyataan, banyak orang tua memilih sekolah swasta untuk mendapatkan fasilitas belajar lebih nyaman baik dari sekolah maupun dari pengajarnya. Unsur-unsur pendidikan menjadi penentu keberhasilan proses peningkatan mutu pendidikan dalam pencapaian tujuan pendidikan di satuan pendidikan. Penelitian ini bertujuan untuk mendeteksi pembagian cluster terkait jumlah sekolah negeri dan swasta tingkat sekolah menengah atas tiap provinsi di Indonesia dengan menerapkan model probabilitas Bernoulli. Berdasarkan analisis yang sudah dilakukan dapat disimpulkan bahwa persebaran cluster menggunakan model probabilitas Bernoulli pada jumlah sekolah negeri tingkat menengah atas di indonesia memiliki 5 cluster dan banyak tersebar di bagian Indonesia wilayah tengah dan timur. Sedangkan pada jumlah sekolah swasta tingkat menengah atas di indonesia memiliki 6 cluster dan banyak tersebar di bagian pulau jawa. Provinsi-provinsi yang masuk ke wilayah cluster tersebut berarti memiliki karakteristik yang mirip yang dimilikinya sehingga mengelompok kedalam satu kelompok yang sama. In rural areas, public schools are usually in great demand because of the relatively affordable costs of education. But in fact, many parents choose private schools to get more comfortable learning facilities from both the school and the teachers. The elements of education are the determinants of the success of the process of improving the quality of education in achieving educational goals in educational units. This study aims to detect the division of clusters related to the number of public and private high school level schools in each province in Indonesia by applying the Bernoulli probability model. Based on the analysis that has been done, it can be concluded that the distribution of clusters using the Bernoulli probability model is that the number of senior high school public schools in Indonesia has 5 clusters and many are scattered in the central and eastern parts of Indonesia. Meanwhile, the number of high school private schools in Indonesia has 6 clusters and many are scattered in parts of the island of Java. Provinces that are included in the cluster area mean that they have similar characteristics so that they are grouped into the same group.

Abstract

In modern times, many people rely on sophisticated technology to meet their needs. Already many technologies today can replace the role and function of society in the field of investment. There are many ways to fulfill the lives of these people, such as Bitcoin investment. Bitcoin is a digital asset that only exists in digital form by means of peer-to-peer work. To maximize profits, it is necessary to forecast Bitcoin prices when it will go up or down. This study tries to address the changes in Bitcoin prices whether to go up or down the next day with an artificial neural network model. The editor used in this study is the LSTM method. The data used is the Bitcoin blockchain data, namely time-series data in a one-day period from 1 January 2018 to 31 May 2019. Obtained forecasting results in June 2019 for Bitcoin to rise slowly and an accuracy value of 97.5% based on MAPE with the first day worth $8901.50.
