Abstract

Kapasitas penyerapan energi industrial safety helmet sangat dipengaruhi oleh bahan yang digunakan dalam pembuatan helm. Pada umumnya industrial safety helmet terbuat dari High-Density Polyethylene (HDPE) dan Polycarbonate. Penggunaan material komposit masih jarang digunakan pada proses pembuatan industrial safety helmet. Material komposit memiliki sifat yang unggul seperti ringan, kekuatan dan kekakuan yang cukup tinggi. Dengan keunggulan sifat yang dimiliki oleh komposit, sehingga pada penelitian ini dikembangkan industrial safety helmet yang terbuat dari komposit Glass Fiber Reinforced Polymer (GFRP). Penelitian yang dilakukan berfokus pada perancangan dan proses manufaktur industrial safety helmet komposit GFRP. Pertama proses perancangan industrial safety helmet dikembangkan dengan menyusun DR&O (Design Requirement & Objective). Proses selanjutnya adalah proses manufaktur industrial safety helmet dengan material komposit GFRP 3 lapis dengan metode pembuatan hand lay-up. Hasil penelitian didapatkan bahwa industrial safety helmet dengan bahan komposit GFRP berhasil dikembangkan dan memiliki keunggulan lebih ringan dibandingkan dengan Industrial safety helmet standard SNI.

Abstract

The growth of congregation activities in Aceh's old mosques has contributed to the area expansion of the old mosques. This article examines three case studies of old mosques in Aceh that represent three scenarios of spatial expansion, including:  mihrab extension integrated into the old mosque, side expansion attached to the old building, and expansion by adding a new mosque building. Three old mosques under study were Teungku Di Anjong Mosque in Banda Aceh, the Asal Penampaan Mosque in Gayo Lues, and the Gunong Kleng Mosque in West Aceh. This paper aims to analyze the mosque's spatial connection from three architectural aspects:  (1) Pattern of Additional Area, (2) Functionality and Other Features, (3) The Architectural Forms and Materiality of the old and new mosques. A qualitative study was employed through the analysis of architectural and visual images of the three mosques. The study found that adding new spaces to the three mosques significantly divides old and new mosques. The main function of the mosque as a place of worship intertwines with its function as a center of cultural activities as found in the old and new spaces. Furthermore, the old mosque architecture influenced modern mosques, although not completely. The old form harmonized with new materials to reconcile with contemporary construction methods.
