Abstract

Memasuki era Big Data, pihak yang mampu mengolah dan memanfaatkan data-data yang bervolume besar, cepat berubah, variatif, dan kompleks, dapat mengambil keuntungan yang besar. Mengacu pada manfaat besar yang dapat ditawarkan oleh teknologi Big Data, menarik untuk melihat sejauh mana Teknologi Big Data sudah dimanfaatkan di Indonesia, khususnya di lembaga pemerintahan maupun lembaga swasta, dan tantangan apa saja yang muncul dalam penerapannya.. Pengumpulan data pada penelitian ini dilakukan melalui teknik studi literatur. penulis melakukan pencarian dan mempelajari beberapa referensi seperti buku, jurnal maupun artikel ilmiah yang berkaitan dengan penelitian ini. Selanjutnya akan dipaparkan faktor-faktor yang memicu perkembangan pesatnya, klasifikasi data yang terdapat dalam Big Data, serta tahapan untuk mengelolanya.

Abstract

Layanan cloud computing dihadirkan sebagai upaya untuk memungkinkan akses sumber daya dan aplikasi dari mana saja melalui jaringan Internet di era digital. Pada penulisan ini untuk memberikan gambaran mengenai cloud computing, review mengenai cloud computing terbagi menjadi 3 bagian yaitu karakteristik cloud computing, model layanan cloud computing dan model implementasi cloud computing. Karakteristik cloud computing terdiri dari on-demand self service, broad network access, resource pooling, rapid elasticity ,dan measured service. Penelitian ini dilakukan secara deduktif, dilakukan dengan cara mengkaji layanan cloud computing secara umum kemudian dilakukan pengkajian khusus mengenai perkembangan di berbagi bidang. Setelah dilakukan kajian deduktif maka peneliti akan mengidentifikasi permasalahan dan melakukan studi literatur terkait topik penelitian. Model layanan cloud computing melakukan terdiri dari software as a service (saas), platform as a service (paas) dan infrastructure as a service (iaas). Sedangkan untuk model implementasi cloud computing terdiri dari public cloud, private cloud, hybrid cloud dan community cloud. Pembahasan mengenai beberapa pendapat dan penelitian terdahulu tentang teknologi cloud computing, selanjutnya ditinjau kelebihan dan kekurangan yang dapat ditimbulkan atas implementasi.

Abstract

The development of this technology makes humans design various tools that can support daily work, such as digital height measuring devices that can work automatically. XYZ Boutique is a clothing boutique located in the Tangerang Regency area. One of the innovations in the application of technology at the XYZ boutique is utilizing microcontroller technology to measure the height of visitors who come. The visitor's height data is used to determine the appropriate clothing model and determine the size and model of clothing. So, boutique employees can offer or recommend clothes according to height. The author uses 3 methods in data collection, namely observation of visits to XYZ boutiques, interviews with boutique owners and employees to find out the problems of tools and equipment needs and conducting journal literature studies related to research conducted by microcontrollers and Ultrasonic Sensors HC-SR04. The result of the research is that a series of automatic height measuring instruments with a microcontroller can be used as an innovation to replace manual height measuring instruments. The results of measuring the height of visitors who come to the boutique will automatically be displayed on the LCD, which can be used as a reference for boutique employee data to recommend clothes based on height grouping.

Abstract

Indonesia is one of the countries located in the Pacific Ring of Fire, where three tectonic plates meet. This makes Indonesia very vulnerable to natural disasters such as earthquakes, volcanic eruptions, and tsunamis. These natural phenomena occur very frequently, as evidenced by events such as those that have occurred on the island of Sumatra. This study aims to classify earthquake data in the Sumatra Islands based on hypocenter using the Naive Bayes Algorithm. The study uses earthquake datasets specifically from the Sumatra Islands, which are divided into training and testing data. The results of the study indicate that classification can be performed using the Naive Bayes Algorithm based on three categories, ranging from shallow earthquakes, moderate earthquakes, to deep earthquakes.

Abstract

In daily life activities, every human being will be faced with various problems that will require them to make the right decisions in order to solve these problems. So to make important decisions, more careful, unhurried and mature considerations will be needed. Decision making is also carried out by organizations and companies, for example at PT. To make it easier to select appropriate exemplary employees, based on the company's needs, a decision support system using the SMART method is used. The SMART method is more widely used in calculating alternatives and ranking, because it is simple in responding to researchers' needs in making decisions and analyzing responses. The author collected the data needed to be processed in selecting exemplary employees. This stage of the data collection process was obtained by the author from observation, interviews and literature studies. Criteria for evaluating exemplary employees include attendance, discipline, responsibility, work targets and length of service. After evaluating alternative employees, an exemplary employee with the highest score was obtained.

Abstract

The development of information technology in the current digital era encourages various sectors to enhance efficiency, competitiveness, and service reach through digital transformation. One form of its implementation is the development of online product sales systems. Toko XYZ, a business engaged in shoe sales, still relies on conventional sales methods through physical stores, thus facing challenges in reaching a wider range of customers amid changing consumer behavior. This study aims to develop a website-based sales system to support the digitalization of business operations at Toko XYZ. Data collection methods included observation, interviews, and literature studies to identify system requirements. The developed e-commerce website is designed to expand market reach, facilitate transaction processes, and provide a more convenient shopping experience for customers. System evaluation was carried out using the Technology Acceptance Model (TAM) approach, with measurements conducted through a Likert scale-based questionnaire. Analysis results show that the user acceptance rate for the website reached 89%, which falls into the "strongly agree" category. These findings indicate that the implementation of a website-based online sales system can improve sales effectiveness, expand the customer base, and strengthen Toko XYZ's competitive position in the digital market.
