Analisis Performansi OSPFv3 Pada Jaringan IPv6 Menggunakan Free Range Routing
No full textPengalamatan Internet Protocol atau IP merupakan salah satu faktor daam kemajuan internet saati ini. IPv6 merupakan standar pengalamatan IP yang digunakan untuk mrnggantikan IPv4 yang jumlahnya sudah sangat terbatas dan mulai habis. IPv6 sendiri masih cukup jarang digunakan oleh pengguna di dunia, di mana untuk sekarang masih sekitar 35% - 40% pengguna di seluruh dunia. Namun dengan banyaknya pengguna sekarang tidak menutup kemungkinan IPv6 ini kedepannya akan benar-benar menggantikan IPv4. Dengan hadirnya IPv6 ini tentu perlu adanya routing protokol yang nantinya dapat mengatur pemilihan jalur pengiriman data untuk berbagi informasi tentang jaringan dan koneksi antar router. Adapun protokol roting yang dapat digunakan pada jaringan IPv6 adalah OSPFv3 merupakan pengembangan dari OSPF dan OSPFv2 yang digunakan pada jaringan IPv4. OSPFv3 pada dasarnya merupakan protokol routing yang berfokus di jaringan IPv6. Mampu menerapkan protokol routing OSPFv3 pada jaringan IPv6. Membuat sebuah jaringan yang menerapkan aturan routing OSPFv3 pada free range routing OSPFv3 merupakan jenis protokol routing yang digunakan untuk menghubungkan segmen jaringan yang berbeda untuk mengirimkan paket data khususnya pada jaringan IPv6. Kualitas performa dalam melakukan pengiriman paket data dapat dipengaruhi oleh banyaknya transfer data yang terjadi secara bersamaan dan jelek atau bagusnya performa protokol routing diukur berdasarkan standar klasifikasi setelah melakukan analisis QoS

No full textThe South Korean entertainment industry, particularly K-Pop, uses social media to connect the idols to their fans worldwide. This strategy is also used by Seventeen. K Pop idols Seventeen through their agencies manage continuous interactions, making fans believe they are close and know their idol well. The use of platforms also emphasizes the media multiplexity to connect with their mediated parasocial interaction. This phenomenon raises the question of how fandom Carat, the group of fans of Seventeen, weaves the parasocial interaction on Seventeen’s Youtube and Weverse. This research investigates the parasocial interaction done by Carat on Seventeen's Youtube and Weverse and the web of media or known as media multiplexity which emerges within the activity of idolization. This research uses a quasi-qualitative approach. Data collection techniques used in this study are interviews and document study. Based on the results, we found that Carat became their identity presented in parasocial interactions. Carat conducted mediated parasocial interactions on Youtube and Weverse. Through the media multiplexity Carat created a sense of comfort and familiarity coming from repeated exposure to Seventeen’s media and content. The next finding is that Carat felt that they were not close to Seventeen if they didn’t actively weave and connect their parasocial interaction.

No full textThis research aims to redesign an ergonomic tourist boat ladder to improve the comfort and safety of tourists in the context of marine tourism. Tanjung Luar Tourism Village, East Lombok, was chosen as the research location due to the high potential of tourists using boats as a means of transportation to marine tourism destinations. Currently, many tourist boats are not equipped with safe and comfortable stairs, increasing the risk of accidents. The method used in this research is Quality Function Deployment (QFD), which identifies the needs and preferences of tourists through surveys and questionnaires. The research sample consisted of 57 respondents, including tourists, boat crew, and ergonomics experts. The House of Quality (HoQ) results showed that the main needs of tourists include comfortable and safe handrails, anti-slip stair surfaces, and corrosion-resistant stair materials. Based on these needs, three alternative boat ladder designs were developed that consider aspects of safety, durability, and ease of use in marine environmental conditions. Products with ergonomic handrails, stainless steel material, and design flexibility were prioritized in the development. These designs are expected to not only provide a safer and more comfortable solution for users but also contribute to the development of safety standards for tourist boats in Indonesia. This research provides a foundation for the improvement of tourist boat facilities, especially in areas with great potential in marine tourism
Ergonomic analysis on wheelchair redesign to improve user health and safety
No full textThis research aims to redesign a wheelchair to enhance comfort and safety based on the ergonomic needs of users through a holistic ergonomic approach. The study employs the FMEA (Failure Mode and Effects Analysis) method to identify product failures in wheelchairs and determine preventive measures using the Risk Priority Number (RPN), calculated from Severity (S), Occurrence (O), and Detection (D). A biomechanical assessment using REBA (Rapid Entire Body Assessment) evaluates the posture and movements of wheelchair users and identifies factors contributing to ergonomic risks. The FMEA analysis revealed three failure modes with the highest RPN values: "head drooping" (192), "hands hitting the wheels" (120), and "feet drooping" (112). The REBA assessment indicated a final score of 9, signifying a high risk of injury, necessitating immediate corrective actions. In response to the findings from FMEA and REBA, a new wheelchair design is proposed, incorporating features such as neck support, a hydraulic system for the back, and calf supports. Additionally, the wheelchair dimensions will be adjusted based on the users' anthropometric measurements to ensure better ergonomics
