Abstract

Proyek Light Rail Transit (LRT) Ruas Cawang-Dukuh Atas yang sedang dilaksanakan oleh PT. Adhi Karya Tbk. berpotensi tinggi terjadi risiko kecelakaan kerja. Penelitian dilakukan untuk mengevaluasi penerapan SMK3 oleh PT. Adhi karya Tbk. dengang melakukan identifikasi tingkat penerapannya dan memberikan evaluasi apakah masih ada yang perlu diperbaiki. Metode yang digunakan adalah kualitatif deskriptif kemudian melakukan penilaian kesesuaian penerapannya terhadap Australian Standard/New Zealand Standard (AS/NZS) ISO 31000:2009. Data sekunder diperoleh dari sumber Departemen QHSE Perkereta apian PT. Adhi Karya Tbk dan informasi elektronik yang sudah dibuat, sedangkan data primer diambil dengan kuesioner kepada pekerja dan wawancara dengan karyawan. Berdasarkan data hasil penelitian dan analisis secara kualitatif didapatkan tingkat kesesuaian terhadap Australian Standard/New Zealand Standard (AS/NZS) ISO 31000:2009 mencapai 90 %, risiko kecelakaan kerja dapat dikontrol dengan baik, dan tingkat terjadinya insiden kecelakaan dapat dinihilkan tanpa mengurangi kinerja produksi atau pencapaian progress pekerjaan. Saran untuk perbaikan ke depan perlu dilakukan adalah menstandarkan kepada seluruh personil K3 harus bersertifikat, dan menjaga konsistensi pelaksanaan SMK3 yang sudah baik.

Abstract

In order to improve the function of the Mosque in this case, mushalla as a place of worship and the construction of the people in particular, where people's lives are so compound and crowded, and to increase piety in performing worship (congregational prayer) as best as possible, prospering the Mosque has a positive influence for the development of the community in order to improve the quality of life of the community and the country. In order for religious syi'ar to be more echoed because it requires some improvement because of the inadequate physical condition of the building, it is necessary to renovate the construction of Mushalla and Al-Qur'an Education Park (TPA) which is regressive, is a program of mushalla management in Curug Village, RT.06 RW.04, Bojongsari Subdistrict, Depok City, West Java for the creation of a solemn and comfortable atmosphere of worship. The activities began with a coordination meeting with mushalla administrators in Curug Village, RT.06 RW.04, Bojongsari Subdistrict, Depok City, West Java, and residents around the Mosque, planning, drafting, and calculation in the making of Unit Price Analysis (AHS) in order to be analyzed and carried out on time. Mushalla is a center of community activities and development. And besides that, we should be able to position the Mosque as a unifying forum for Muslims

Abstract

The aviation industry increasingly relies on composite materials to optimize performance and reduce weight in high-speed aircraft structures. These materials offer superior strength-to-weight ratios, corrosion resistance, and design flexibility. Understanding the mechanical properties of composite materials is essential for enhancing the safety and efficiency of high-speed aircraft. This research aims to analyze the strength characteristics of composite materials used in high-speed aircraft structures. The study focuses on evaluating the mechanical properties and performance under various loading conditions to determine their suitability for aviation applications. An experimental approach was employed, involving the fabrication of composite samples using different matrix and fiber combinations. Tensile, compressive, and flexural tests were conducted to assess mechanical properties. Data were collected and analyzed to evaluate the performance of each composite configuration under simulated operational conditions. The findings indicated that hybrid composite materials exhibited the highest strength and stiffness, outperforming traditional materials. The tensile strength of the best-performing composite reached up to 600 MPa, while flexural tests showed significant resistance to deformation. These results highlight the potential of advanced composites to enhance the structural integrity of high-speed aircraft. The research underscores the importance of selecting appropriate composite materials for high-speed aircraft applications.
