Configuration Management Dengan Ansible Dan Telegram Untuk Automasi Laboratorium Komputer
Get PDFManajemen sistem secara manual terbukti menjadi tugas yang melelahkan dan tidak efisien di era
teknologi yang terus berkembang. Tugas-tugas administratif seperti pembaruan sistem, pembaruan perangkat lunak,
pengaturan konfigurasi semua dilakukan dengan tenaga manusia. Tugas tersebut menghabiskan waktu jika dilakukan
secara berulang-ulang dan menghabiskan tenaga. Selain itu, manajemen sistem secara manual juga rentan terhadap
kesalahan manusia dimana setiap perubahan dalam sistem harus dilakukan secara konsisten dan terdokumentasi. Dalam
hal ini Laboratorium Jurusan Teknik Informatika dan Komputer masih mengadopsi cara tersebut. Laboratorium JTIK
pada umumnya digunakan untuk keperluan praktikum dan pembelajaran mahasiswa. Untuk menjaga kualitas dari
pembelajaran dalam laboratorium, dibutuhkan sebuah sistem pendukung yang dapat melakukan otomatisasi pada tugas
tersebut. Sistem Configuration Management yang dibangun akan menggunakan Ansible dan Telegram untuk automasi
laboratorium komputer di JTIK. Hasil pengujian menunjukkan beberapa metode konfigurasi otomatis dengan Ansible
memberikan waktu yang lebih singkat dalam menyelesaikan tugas-tugas secara efisien dibandingkan metode konfigurasi
manual. Metode konfigurasi otomatis lebih efisien dalam penggunaan sumber daya CPU dengan rata-rata 6,25%
dibandingkan konfigurasi manual dengan rata-rata 15,67%. Namun, konfigurasi manual lebih efisien dalam penggunaan
sumber daya memory dengan rata-rata ketersediaan memory konfigurasi manual sebesar 3522 MB, sedangkan konfigurasi
otomatis sebesar 3478 MB. Dalam keseluruhan hasil, implementasi CM dengan Ansible dan Telegram berhasil
meningkatkan efisiensi dan produktivitas dalam pengelolaan laboratorium komputer di JTIK.Manajemen sistem secara manual terbukti menjadi tugas yang melelahkan dan tidak efisien di era teknologi yang terus berkembang.

Performance Analysis of Earthquake-Resistant Building Structures with Conventional Columns and Flat Columns
Get PDFThe structural integrity of a building depends on the ability of its column components to support the loads above them. The strength of a column is greatly influenced by its shape and dimensions. This study aims to analyze the performance of earthquake-resistant building structures with conventional columns and flat columns. This research was conducted by modeling two variations of an 8-story building structure using ETABS software, which are Model 1 with conventional columns and Model 2 with a combination of conventional columns and flat columns using L-shaped and T-shaped columns. The analysis of earthquake loads was performed by using the response spectrum analysis method, while the structural performance and the collapse mechanism of the building were performed by using the pushover analysis method. The results showed that Model 1 had smaller values of internal force, base shear, displacement, and inter-storey drift than Model 2. The results of the structural performance level in both models had the same level, which is Damage Control (DC). The structural collapse mechanism in Model 1 has qualified the requirement of strong column weak beam, while Model 2 has not met this requirement and falls into the column sway mechanism because the first collapse happened in columns. Based on the statistics analysis, there is no significant difference between Model 1 and Model 2, but in terms of maintaining the room area and aesthetic interior, Model 2 with flat columns has more value
DECODING CULTURAL NUANCES: SUBTITLING CULTURAL TERMS IN NETFLIX ORIGINAL SERIES “GADIS KRETEK”
Get PDFAudiovisual translation, particularly subtitling, plays a crucial role in bridging cultural gaps for a global audience by making local expressions and culturally-bound references accessible across languages. The globalization of media content has increased the demand for accurate and culturally sensitive subtitles, prompting a deeper examination of how cultural nuances are conveyed in translation. This study investigates the translation of cultural terms in the Netflix Original Series Gadis Kretek. The objectives are to (1) classify cultural terms based on Newmark's (2017) framework, (2) analyze the subtitling strategies used, following Pedersen's (2011) theory, and (3) evaluate translation accuracy using Nababan et al.'s (2012) criteria. Employing a descriptive qualitative method and Spradley's (1980) analytical approach, 206 data of cultural terms were identified. Social Culture was the most common category, comprising 136 data (66.01%), followed by Material Culture (21.85%), Organization (8.25%), and Ecology (3.89%). This study found six subtitling strategies: retention, specification, direct translation, generalization, substitution, and omission. Direct translation was the most frequently used strategy (61.65%), while specification was the least used (1.46%). Translation accuracy was assessed through a Focus Group Discussion (FGD), which showed that strategies such as Direct Translation and Retention achieved higher accuracy by preserving cultural context. Conversely, Generalization and Omission often resulted in lower accuracy due to a loss of cultural specificity. Overall, the translation quality of cultural terms in Gadis Kretek was rated as accurate, with an average score of 2.93
