Abstract

Reduced Beam Section (RBS) joints generally reduce the plastic section of column-beam joints or column faces by reducing the flange width in the plastic joint area. The research compares the behavior and internal forces in the column-beam joints in conventional and Reduced Beam Section column-beam joints. The method used is a method of numerical analysis of research variables by standards and regulations. A notch with a reduction of 45% can be used as a first step in designing an RBS connection. The reduced beam section connection with a notch depth of 35 mm produces a maximum moment on the face of the column (Mf = 37800.466 Kgm) less than the plastic moment on the beam (ϕd Mpe = 44807.117 Kgm), The reduced beam section connection produces a shear force that occurs Vu = VRBS is (Vu = VRBS = 180.73 Kn) less than the allowable shear resistance (Vn = 280.8 kN), and the Reduced Beam Section (RBS) connection in the structure is more efficient than using conventional joints

Abstract

This study investigates the role of digital leadership in fostering technopreneurship in Indonesia, a rapidly evolving sector shaped by technological advancements and digital transformation. As technological innovation and data-driven decision-making are central to the success of technopreneurs, understanding the role of leadership in this context is critical for sustainable growth. The primary aim of this research is to explore how digital leadership can enhance technopreneurship in Indonesia by promoting collaboration, innovation, and operational efficiency. The method a literature review and bibliometric analysis are employed to identify key trends and research patterns in digital leadership and its impact on the technopreneurship ecosystem. By analyzing data from various sources, the study provides an in-depth examination of the current state of the field. This research contributes a unique perspective by combining bibliometric analysis with traditional literature review, providing a comprehensive, data-driven approach to understanding how digital leadership drives technological innovation. It also emphasizes the challenges technopreneurs face, such as the digital skills gap and regulatory barriers, areas often overlooked in previous studies. While previous research has explored the general impact of digital leadership on business transformation, this study fills the gap by specifically focusing on Indonesia technopreneurship ecosystem and its unique challenges. The findings confirm that digital leadership plays a pivotal role in overcoming obstacles like unequal access to technology and driving innovation in technopreneurship. The study recommends strategies such as enhancing digital skills, investing in infrastructure, and fostering more flexible regulations to support the growth of technopreneurship in Indonesia.

Abstract

Balok kastela merupakan solusi efisien dalam desain struktur modern karena mampu mengurangi berat material tanpa mengorbankan kekuatan secara signifikan. Namun, keberadaan bukaan pada badan balok menimbulkan konsentrasi tegangan dan risiko tekuk lokal, sehingga diperlukan evaluasi keandalan strukturnya. Penelitian ini bertujuan menganalisis Faktor Keamanan Global (FKG) dan tahanan desain balok kastela heksagonal terhadap beban lentur. Pendekatan analitis dilakukan dengan mempertimbangkan variasi dimensi profil, geometri bukaan, serta parameter keandalan seperti indeks keandalan (β), faktor sensitivitas, dan koefisien variasi material. Hasil analisis menunjukkan bahwa kapasitas lentur (Mn) balok berkisar antara 0,48 kNm hingga 16,36 kNm, tergantung pada dimensi profil dan geometri bukaan. Nilai FKG bervariasi antara 1,297–1,485, dipengaruhi oleh standar yang digunakan (misalnya, β = 3,8 pada ISO 13822:2010 menghasilkan FKG lebih tinggi dibandingkan β = 2,5 pada NEN 8700:2009). Semakin tinggi indeks keandalan, semakin besar FKG, tetapi nilai tahanan desain (Rd) menjadi lebih kecil, mengindikasikan desain yang lebih konservatif. Studi ini juga mengungkap bahwa SNI 1729:2020 (dengan FKG 1,67) lebih ketat dibandingkan standar internasional lainnya. Kesimpulannya, pendekatan FKG memberikan gambaran tentang desain balok kastela, dimana nilai Rd ditentukan oleh β target dan umur bangunan, dimana jika β tinggi menghasilkan FKG tinggi begitu pula sebaliknya.
