Abstract

The Thousand Islands, a key marine tourism destination in Indonesia, faces serious threats from environmental pollution. Plastic waste, oil spills, and unsustainable tourism activities damage the marine ecosystem, human health, and the socio-economic well-being of the local community. This study aims to examine the sources of pollution, its impacts, and mitigation efforts implemented in the Thousand Islands. The research method utilized a literature 1the primary pollution comes from microplastics, oil spills, and illegal tourism and fishing activities. This environmental damage reduces marine productivity, poses health risks, and fuels social inequality. Mitigation efforts need to be strengthened through plastic reduction policies, conservation education, and integrated waste management.

Abstract

Field Work Internship (PKL) is an experiential learning activity aimed at improving student competency through the direct application of theory learned in class. This PKL was conducted by a third-semester student at PT. Inkoneksi Izi Konsultan for 90 working days. Students were involved in the organization, supervision, and control of a construction project, including schedule planning, cost and material control, quality control and OHS, and daily and weekly project reporting. Key technical decisions included the recommendation to install a 500x500 Heavy Duty box culvert channel toward the road and the closure of half the road due to dense utilities along the roadside, as well as the proposed change in channel dimensions from 300x300 to 500x500. The PKL results demonstrated that the field experience provided a concrete understanding of the project's complexity, particularly in aspects of coordination, safety, congestion risk, and time management. A comparison between theory and practice revealed a gap in understanding of work methods that could only be bridged through direct experience. Thus, PKL plays a crucial role in developing students' managerial, technical, and problem-solving skills in the construction field

Abstract

The steel structure design for the SMPN 50 Bekasi commercial building was carried out to produce a safe, strong, and efficient structural system in terms of material usage and construction costs. The steel structure was selected based on its advantages of high strength, good ductility, and ease of fabrication and field implementation. The planning method used in this study is Load and Resistance Factor Design (LRFD), which considers load factors and strength reduction factors to ensure the structural safety level meets regulatory requirements. The structural design refers to Indonesian national standards, namely SNI 1729:2020 for steel structure specifications, SNI 1727:2020 for building loading, and SNI 1726:2019 for earthquake resistance. The planning stages include collecting building data, determining dead loads, live loads, and earthquake loads, modeling the structure using structural analysis software, and analyzing internal forces in the form of axial forces, bending moments, and shear forces. These internal forces are then used as the basis for designing the main structural elements, namely beams, columns, and steel connections, using the LRFD method. The design results indicate that the selected steel profile is capable of withstanding the factored load combination and meets the requirements for flexural, shear, and compressive strength, as well as structural stability. Therefore, the steel structure design for the SMPN 50 Bekasi commercial building using the LRFD method can be used as a reference for safe, efficient planning that complies with applicable regulations
