Abstract

Interpolasi splin kubik merupakan sebuah metode pencocokan kurva yang sangat populer karena mudah diterapkan dan menghasilkan kurva yang mulus. Pada artikel ini dibahas pengembangan metode interpolasi splin kubik untuk syarat batas terapit yang diambil dari rumus eksplisit beda hingga dengan ketelitian orde lebih tinggi. Pengembangan metode ini diterapkan pada masalah pelacakan trajektori objek (object tracking). Secara khusus, masalah ini diujikan untuk splin kubik terapit orde dua, dan hasil interpolasinya dibandingkan dengan hasil pada splin kubik alami dan splin kubik terapit orde satu. Dari simulasi data trajektori yang dibangkitkan dari kurva spiral Archimedean, diperoleh nilai galat total untuk splin kubik alami, terapit orde satu dan terapit orde dua masing-masing sebagai berikut: ,  dan . Berdasarkan hasil tersebut, disimpulkan bahwa interpolasi splin kubik terapit orde dua yang dikembangkan pada artikel ini dapat menghasilkan trajektori objek yang lebih akurat dibandingkan splin kubik alami dan splin kubik terapit orde satu. AbstrractCubic spline interpolation is a very popular curve fitting method since it is easy to implement and produces a smooth curve. This article discusses the development of the cubic spline interpolation method for a clamped boundary condition taken from finite-difference explicit formulas with higher-order accuracy. The development of this method is applied to an object tracking problem. In particular, this problem is examined for second-order clamped cubic spline, and the interpolated results are compared with those for natural and first-order clamped cubic splines. From the simulation of trajectory data generated from the Archimedean spiral curve, the total error values for natural, first-order, and second-order clamped cubic splines are respectively ,  and . Based on these results, it is concluded that the second-order clamped cubic spline interpolation developed in this article can produce a more accurate object trajectory than the natural and first-order clamped cubic splines.

Abstract

SMK Al-Farisi Leles currently provides hotspot services which is an area where there is a wireless internet connection that can be accessed through Laptops, Gadgets, and other devices that support the technology. With hotspots in SMK Al-Farisi Leles, users can enjoy internet access in the hotspot area without having to connect by cable. Hotspots in SMK Al-Farisi can be accessed directly by anyone because the authentication system is still conventional which is authentication that enters a password to be connected to the hotspot network, this often results in an unstable connection because there is no limit to being connected to the hotspot network so that people outside the school community who are in the hotspot area can also be connected freely. Therefore, the author implements SMS Gateway-based Authentication User in SMK Al-Farisi where the user is required to request first to obtain a hotspot account via SMS with the provision stipulated by the admin. The results showed that this authentication system runs smoothly and can manage users connected to hotspot networks.

Abstract

Early Childhood Education (ECCE) has an important role in shaping the basis of children's knowledge and understanding of the surrounding world, including animal recognition. At Al-Hidayah ECD, animal recognition materials currently use only picture cards, songs, and stories, conducted four times a week. However, there are drawbacks to this method, which is that it only introduces animals based on the letter prefixes of the alphabet and has not introduced the type of food and ecosystem of animals. The results showed that the success rate of animal recognition by students was only 55% with the usual method. In an effort to improve animal recognition methods, this research aims to develop learning media innovations using Augmented Reality (AR) technology with a focus on recognizing animal types based on food and its ecosystem. In this study, researchers chose the Multimedia Development Lyfe Cycle (MDLC) method because this method is suitable for designing and developing multimedia applications. This research was conducted at PAUD Al-Hidayah. The creation of this learning media application was made using the main software Unity 3D. Based on the results of questionnaires filled out by students and teachers, it can be said that animal recognition learning media based on food types and ecosystems that contain video material is equipped with audio, displays 3D animal objects with markers, then contains interestingly made quizzes. The results obtained from the User Acceptance Test (UAT) get results with a percentage of 96.7%. With these positive results, it is hoped that the use of AR for the learning of PAUD Al-Hidayah students can understand more interactive learning.

Abstract

Absensi karyawan merupakan proses pendataan kehadiran yang berlangsung setiap harinya di PT. Codepolitan Integrasi Indonesia, hal ini dilakukan agar dapat membantu dalam proses rekap kehadiran karyawan. Pengelolaan tersebut masih bersifat manual yang menyebabkan ketidakefektifan dalam melakukan absensi untuk memudahkan pengelolaan data karyawan. Dibutuhkan teknologi bernama geolocation, oleh karena itu penulis membuat suatu aplikasi berbasis web dengan memanfaatkan geolocation untuk membantu proses absensi karyawan di PT. Codepolitan Integrasi Indonesia. Dengan menggunakan teknologi geolocation suatu sistem mempunyai kemampuan untuk menentukan posisi suatu objek atau orang yang berada di bumi dengan menggunakan koordinat geografis (latitude dan longitude). Penerapan geolocation pada aplikasi digunakan sebagai pengaman aplikasi dimana pada aplikasi ditentukan lokasi titik koordinat dengan titik radius maksimal 1 kilometer. Oleh karenanya penulis membuat aplikasi absensi online dengan metode geolocation. Sistem ini terbukti dapat diterima dengan baik oleh karyawan PT. Codepolitan Integrasi Indonesia.

Abstract

The current digital era is characterized by cross-platform multimedia consumption, which has become the backbone of information and entertainment, with video content dominating more than 82% of total global internet traffic. The main challenge of adaptive compression for multi-platform multimedia streaming lies in device heterogeneity, network conditions, and the need for Quality of Experience (QoE), as adaptive compression adjusts the bitrate, resolution, and encoding level in real-time. The aim of this research is to explore these issues through a literature review study to identify the scope, taxonomy, gaps, and proposed future research directions. The method used is a literature review covering 51 publications (interval 2019-2025) to examine conceptual aspects, system taxonomy (System Architecture Layer, Adaptation Strategy, Compression Technique, and Artificial Intelligence Model), and to identify research gaps. The review results show that streaming efficiency depends on adaptive compression mechanisms, with a research paradigm shifting from rule-based adaptation toward intelligent adaptive compression. Despite these developments, significant unaddressed gaps remain, particularly concerning synchronization across platforms based on different codecs, low-latency real-time AI compression, robust network adaptation solutions for 5G/B5G, and cross-dimensional integration within a single framework. Future research directions are proposed in platform-specific synchronization models, multi-constraint compression, adaptive AI for slicing, and energy optimization through Federated Learning.
