Abstract

Pengenalan aktivitas manusia atau Human Activity Recognition (HAR) merupakan salah satu topik yang populer karena besarnya peluang untuk diterapkan di kehidupan sehari-hari. Tujuan dari pengenalan ini adalah untuk mengenali, mendeteksi, dan mengklasifikasikan aktivitas yang dilakukan manusia. Pengenalan aktivitas manusia adalah salah satu teknologi penting untuk memantau dinamisme seseorang sehingga dapat bermanfaat di berbagai hal. Selain untuk menjaga kesehatan, pencegahan penyakit, dan membantu menentukan jenis olah raga, HAR dapat dimanfaatkan juga untuk diterapkan pada bidang keamanan dan pengembangan teknologi. Penelitian ini menggunakan smartphone sebagai teknologi utama dalam memperoleh data dengan memanfaatkan sensor akselerometer dan giroskop yang telah tertanam di dalamnya. Terdapat 8 macam aktivitas yang diteliti dengan kombinasi lama waktu eksperimen 5, 10, dan 15 detik serta posisi smartphone dipegang bebas maupun di dalam saku celana kanan. Data yang diperoleh terdiri dari 3 sumbu (x, y, dan z) pada setiap sensor yang digunakan. Data tersebut kemudian melalui proses pengolahan dan klasifikasi menggunakan algoritme k-Nearest Neighbor (k-NN). Hasil akurasi yang didapat dalam penelitian ini mencapai 79,56%. Hasil yang diperoleh melalui penelitian ini menunjukkan bahwa perbedaan peletakan smartphone mempengaruhi hasil pengenalan aktivitas manusia secara stabil. Selain itu, perbedaan jumlah data akibat perbedaan lamanya waktu eksperimen dapat mengakibatkan perbedaan lamanya waktu komputasi. Penelitian ini menjadi penting karena hasilnya dapat menjadi batu loncatan bagi penelitian selanjutnya. Beberapa peluang pengembangan juga dilampirkan pada bagian akhir. AbstractHuman activity recognition (HAR) is one of the most popular topics because of the large opportunities for its application in life. The purpose of HAR is to recognize, detect and classify human activities. Human activity recognition is one of the important technologies for monitoring a person's dynamism so that it can be utilized in various ways. Apart from maintaining health, preventing disease, and helping determine the type of exercise, HAR can also be used to be applied in the field of security and technological developments. This study uses smartphones as the main technology in obtaining data by utilizing the built-in accelerometer and gyroscope sensors. There are 8 types of activities studied with a combination of 5, 10, and 15 seconds of experimental time and the position of the smartphone is carried freely or in the right trouser pocket. The data obtained consists of 3 axes (x, y, and z) on each sensor used. The data then processed and classified using the k-Nearest Neighbor (k-NN) algorithm. The accuracy results obtained in this study reaches 79.56%. The results obtained through this study indicate that differences in smartphone placement affect the results of human activity recognition stably. In addition, differences in the amount of data due to differences in the length of the experiment period can result in differences in the length of computation time. This research is important because the results can be used as material for further research assistance. Some development opportunities are also attached at the end.

Abstract

Special Economic Zones (SEZs) aim to boost the economy of a region or even a country. In Indonesia, as of 2022, eighteen regions belonged to SEZs, and Singhasari is among those regions—the only SEZ with a digital economic concept. In its implementation, a Good Governance concept is needed to allow for the organisation of management and the achievement of the goals of the development of the SEZ. Concepts such as Community Participation, Stakeholder Involvement, and Local Ownership will be discussed in this research. On the other hand, technology can be utilised to give value to SEZ. The digitalisation of the SEZ can be used in the implementation of Good Governance concepts as well as attracting people and investors to participate. The concept of digitizing the SEZ Singhasari area utilising Augmented Reality and Virtual Reality can be used to introduce the SEZ of Singhasari. Besides, there are also other features such as legal materials underpinning the development of SEZ Singhasari. This study used the principle of Good Governance that underlies SEZ governance. Meanwhile, the concept of digitalisation with the addition of augmented and virtual reality will be used as one of the breakthroughs to harmonize development in the current technological era. Keywords: Special Economic Zone, Singhasari, Digitalisation, Good Governance.
