Abstract

Analisa elemen pelat terus berkembang sehubungan dengan semakin kompleksnya bentuk struktur. Menganalisa elemen pelat yang kompleks, peneliti menggunakan metode numerik, dalam hal ini metode elemen hingga. Metode elemen hingga sudah banyak digunakan dalam menganalisa pelat elemen, peneliti terus berlomba dalam mengembangkan elemen pelat dan cangkang yang dapat diaplikasi dalam berbagai kondisi dan mempunyai akurasi yang tinggi. Penggunaan elemen segitiga menarik perhatian peneliti karena simplisitas dan fleksibilitas dalam mendiskritisasi elemen yang kompleks. Elemen segitiga tiga nodal MITC3 (Mixed Interpolation of Tensorial Components) merupakan salah satu elemen pelat yang menggunakan elemen segitiga dan merupakan elemen pelat yang terkenal serta banyak digunakan oleh perangkat lunak komersial. Penelitian tentang elemen MITC3 sudah banyak dilakukan terutama dalam kasus statik, pada penelitian ini peneliti menganalisa elemen pelat isotropik MITC3 pada kasus tekuk yang diberi beban mekanikal berupa beban in-plane uniaksial dan biaksial. Penelitian ini bertujuan untuk melihat tingkat konvergensi elemen pelat isotropik MITC3 pada kasus tekuk, penelitian ini diawali dengan melakukan studi literatur, selanjutnya menguji kinerja dan prilaku konvergensi elemen pelat MITC3 pada kasus pelat persegi dengan memvariasikan rasio panjang terhadap tebalnya. Hasil analisa akan dibandingkan dengan referensi yang ada di literatur.

Abstract

Pembangunan suatu konstruksi sangat berhubungan erat dengan suatu struktur yang menyokong konstruksi tersebut. Salah satu yang berperan besar dalam menyokong suatu konstruksi adalah kolom. Penelitian ini dilakukan pada konstruksi baja sistem rangka pemikul momen khusus (SRPMK) 2 lantai yang berada di tanah lunak dengan 2 jenis Pemodelan. Model 1 menggunakan kolom profil WF (Wide Flange) standar SNI BJ 37 dan menggunakan balok dengan profil WF (Wide Flange) standar SNI BJ 37, sedangkan Model 2 menggunakan kolom profil HSS (Hollow Structural Section) Standard JIS G 3466, Grade STKR400 dan mengguna-kan balok dengan profil WF (Wide Flange) Standard SNI BJ 37. Konstruksi baja tersebut menerima beban gravitasi dan beban gempa. Untuk pemodelan dan pengecekan dilakukan menggunakan program bantu SAP2000 v.18.2.0 dan cara manual sesuai SNI 1729-2015. Melakukan analisa perbandingan efektifitas profil WF terhadap profil HSS sebagai kolom yang ditinjau dari simpangan, rasio tegangan dan berat konstruksi baja. Hasil penelitian menunjuk konstruksi yang menggunakan kolom profil HSS (Hollow Structural Section) mempunyai simpangan yang lebih besar, rasio tegangan yang lebih besar dan berat konstruksi baja yang lebih ringan dibanding profil WF (Wide Flange).

Abstract

The development of construction material that is more efficient and friendly continued by researchers. Steel is a material that is widely used in construction, especially hot-rolled steel, the use of cold-formed steel is an innovation where cold-formed steel has more advantages than hot-rolled steel. Many studies of cold-formed steel sections due to applied loads have been carried out to observe the behavior and capacity of the sections. An unlipped channel is a steel section that can be used in buildings, cold-formed steel unlipped channel will be subjected to an axial load to see the behavior and capacity of the section which is the aim of this study. In this study, a numerical analysis of cold-formed steel sections will be performed using the finite element method through ABAQUS software, the numerical analysis is committed based on existing research in the literature. The Sectional capacity resulting from the numerical analysis will be compared with the effective width method approach based on SNI 7971-2013.

Abstract

This study explores the strategic application of Integrated Marketing Communication (IMC) in Islamic higher education by observing Muhammadiyah University Jakarta (UMJ), the first Muhammadiyah university that has been established for 70 years in maintaining its reputation as a modern Islamic campus. Using a qualitative approach through an integrative literature review and observations at Muhammadiyah University of Jakarta regarding IMC, university branding, and digital communication, the analysis shows that UMJ has implemented some IMC principles through coordinated activities from the Public Relations, Multimedia, and Protocol units under the University Secretariat Office. Although these practices demonstrate message synergy, their implementation is not yet structured within the IMC framework because they are still separate from the PMB promotion section. This article proposes the Value Digital Coordination (VDC) Model as a strategic guideline for Islamic universities to integrate value-based persuasion, digital synergy, and institutional coordination in building a modern Islamic campus image. The results of the study confirm that IMC is not merely a promotional tool, but rather a communication ideology that integrates Islamic values of trustworthiness, professionalism, and social responsibility into institutional communication.

Abstract

This study aims to describe the communication strategy of Universitas Muhammadiyah Jakarta (UMJ) in building its brand image through the UniRank 4ICU ranking indicators. As the oldest Muhammadiyah higher education institution, established in 1955, UMJ holds a strategic position in Indonesia’s higher education landscape. Therefore, UMJ bears the responsibility to project an image of excellence, uniqueness, and strong institutional reputation, particularly in the digital era. This research employs a descriptive qualitative approach, guided by Cangara’s theory of communication strategy and Keller’s Customer-Based Brand Equity (CBBE) model. Data collection was conducted through in-depth interviews, and thematic analysis was carried out based on the CBBE framework and UniRank indicators, including referring domains, global rank, domain authority, and trust flow. The findings indicate that UMJ strategically implements these ranking indicators through the management of its official website, social media platforms, and the application of search engine optimization (SEO) techniques. These efforts form part of the university’s broader communication strategy to build a strong institutional brand image. The achievement of a global ranking not only reflects digital communication performance but also serves as a strategic communication tool that reinforces UMJ’s image as a modern, reputable, and Islamic-oriented higher education institution. This study underscores the importance of integrating digital communication strategies with brand image development to enhance institutional competitiveness at the global level.

Abstract

Steel building structures must be designed to safely and efficiently resist gravity and lateral loads. One of the key factors influencing structural performance is the shape and type of column section used, as differences in geometric characteristics affect stiffness, strength capacity, and structural response to lateral loads, particularly seismic forces. This study aims to analyze the effect of using King Cross, Tube, and Wide Flange sections as columns in steel building structures on overall building performance under gravity and lateral loads. Structural modeling was carried out using ETABS software by developing three building models with identical configurations, dimensions, and loading conditions, differing only in the type of column section applied. All models were designed using a Special Moment Resisting Frame (SMRF) system. The results indicate that variations in column section types significantly influence structural performance, where sections with higher stiffness produce smaller inter-story drift and better lateral load response. Furthermore, differences in column sections affect the fundamental period of vibration, internal forces, and strength ratios of structural elements, which in turn impact the efficiency and safety level of steel building structures. These findings are expected to provide useful guidance for structural engineers in selecting the most suitable column section for a given design requirement.Keywords: Steel Column, King Cross, Wide Flange, Special Moment Resisting Frame, Story Drift
