Inelastic Behavior of Steel X-Bracings with Back-To-Back Channel Sections: A Numerical Study
Get PDFThere are two approaches in determining compression capacity of braces in X-bracing type of concentrically braced frames (CBFs) where the compression braces are connected and interacted with the tension braces. One approach is assuming the effective length factor, K, of the braces to be taken as 0.5, while the other approaches suggest more conservative K values and indicate that the compression braces behavior might be affected by the tension braces and connection plates stiffness. Finite element analyses using ABAQUS are conducted evaluate the nonlinear behavior of X-bracings with back-to-back channel sections with varied slenderness ratio and gusset plates flexural stiffness. From the analytical results, it is found that in all evaluated configurations, yielding in tension braces occurs before buckling of compression braces. Although behave inelastically, the tension braces could act as partial restraints for the compression braces at the intersection points, resulting symmetrical buckling shapes when the compression braces reach their axial capacity. Equivalent effective length factors, which are determined from back calculations based on AISC360-22 formulations for compression members, are ranged from 0.36 to 0.46 and from 0.70 to 0.82, for braces with higher and lower slenderness ratios, respectively. Yielding of gusset plates indicates that the corresponding brace lengths should be measured between the designated fold lines. Gusset plates flexural stiffness could also contribute to the compression capacity of the braces
EFEKTIVITAS PENGGUNAAN MICROBUBBLE VENTURI UNTUK SISTEM AERASI PADA TEMPAT PEMBIBITAN NILA
Get PDFBudidaya ikan nila telah menjadi sumber protein penting untuk konsumsi manusia. Namun, keberhasilan penangkaran ikan nila sangat bergantung pada sistem aerasi yang digunakan di kolam penangkaran. Tujuan dari penelitian ini adalah untuk mengevaluasi efektivitas penggunaan microbubble venturi untuk sistem aerasi di kolam penangkaran ikan nila. Eksperimen dilakukan di dua kolam dengan dimensi yang sama, satu kolam menggunakan sistem microbubble venturi dan kolam lainnya menggunakan sistem aerasi tradisional. Penelitian berlangsung selama enam bulan, selama itu parameter kualitas air, kinerja pertumbuhan ikan, dan tingkat kelangsungan hidup dipantau. Hasil penelitian menunjukkan bahwa sistem microbubble venturi secara signifikan meningkatkan parameter kualitas air di tambak, termasuk oksigen terlarut, pH, dan total amonia nitrogen. Selain itu, kinerja pertumbuhan dan tingkat kelangsungan hidup ikan secara signifikan lebih tinggi di kolam dengan sistem venturi microbubble dibandingkan dengan sistem aerasi tradisional.

Gaya Bahasa Lead Berita Pada Kanal Daerah Media RRI.Co.Id
Get PDFIn today's digital era, online media has become the primary choice for the public to access information quickly and easily. These platforms offer a diverse range of content, from business and politics to technology and entertainment. News, as an informational product of online media, plays a crucial role in conveying facts and ideas that are engaging to the audience. According to Sumadiria (2016), news can be categorized into two types: hard news and soft news. The structure of news writing follows specific elements, including the headline, dateline, lead, body, and conclusion. The lead serves as an important summary that captures readers' interest and must address the 5W+1H questions (What, Who, When, Where, Why, and How).This study aims to analyze the application of language style in writing leads on the regional channel of rri.co.id Jakarta network. The methodology employed is descriptive, utilizing data collection techniques such as literature review, direct observation during an industry internship at Radio Republik Indonesia, and interviews with editorial staff. From the analysis of 10 news articles published in December 2023, it was found that only 20% of the leads met the concise criteria (30-45 words), while 80% exceeded this limit. The most frequently used elements were "What" and "Who."The conclusion of this research indicates that the leads in news articles on the regional rri.co.id channel do not fully meet all 5W+1H elements and the necessary concise characteristics to attract readers' attention. This suggests a need for improvement in lead writing to be more effective in delivering information to the public. This study provides insights into the importance of language style in online journalism to enhance news appeal.Nowadays, online media has become the primary source for public to access information.
