Abstract

Dalam proses instalasi lifting deck extension terdapat beberapa metode diantaranya deck laying. Dalam Proses instalasi lifting penentuan metode sangat menentukan dalam keseluruhan aspek teknis pelaksanaannya. Dalam tugas akhir ini dilakukan analisis respon struktur new deck extension pada saat dilakukan proses single point lifting. Spesifikasi lifting equipment pada sling shackle padeye, dan reaksi skidding pada proses instalasi. Respon deck extension menunjukkan bahwa hasil analisis nilai tegangan yang terjadi pada seluruh Connected member dan Non-connected member berada di bawah batas tegangan izin dengan unity check maksimum sebesar 0.95 dan 0.77. Spesifikasi dan konfigurasi lifting equipment pada deck extension dinyatakan aman dan memenuhi kriteria standar API RP 2A-WSD karena seluruh unity check berada di bawah batas izin (≤ 1,0). Hasil perhitungan menunjukkan shackle Crosby G-2130 (SWL 35 MT) dan sling Galvanized Steel Wire Rope (SWL 28 MT) menghasilkan unity check maksimum sebesar 0,926. Sementara itu, konfigurasi dimensi padeye untuk lifting memenuhi tegangan izin dengan combined stress sebesar 0,97. Analisis temporary skid support frame menunjukkan kekuatan struktur yang memenuhi tegangan izin. Unity check temporary skid frame check maksimum berada di bawah batas aman sebesar 0,83. Selain itu, selama proses skidding didapatkan unity check maksimum pada support frame sebesar 0,89 pada kondisi normal dan sebesar 0,91 pada kondisi abnormal (unbalance load 10%). Konfigurasi dimensi padeye untuk memenuhi tegangan izin dengan combined stress sebesar 0.256. Selain itu, analisis kekuatan jacket (inplace) setelah instalasi menghasilkan Unity Check (UC) maksimum sebesar 0,883.

Traffic congestion in Bali Province, particularly in Badung Regency, Denpasar City, and Gianyar Regency, is driven by the high demand for mobility towards shopping centers, tourism destinations, accommodations, educational institutions, and business activities. The government has introduced the Trans Metro Dewata and Trans Sarbagita public transportation systems to reduce private vehicle usage, but their effectiveness remains low due to a service gap in reaching final destinations (the first–last mile). Users tend to prefer punctual, safe, and affordable modes of transport, whereas the large size of current public vehicles is incompatible with the narrow road widths in destination areas. This condition sustains the dominance of private vehicles and increases transportation sector emissions, which contributed 42.67% to Bali's total emissions in 2023. This research and design aim to produce an adaptive, efficient, and sustainable Bali tourist shuttle bus design concept by: (1) identifying tourist mobility issues and the need for shortdistance shuttles between destinations; (2) applying universal design and ergonomics to ensure inclusivity for the elderly and people with disabilities; (3) designing a comfortable interior layout that allows for easy boarding and alighting, as well as providing adequate storage space; (4) developing an exterior design with a distinct Balinese character based on local identity; and (5) integrating the electric vehicle concept. The methods used include literature reviews, field surveys, and interviews with stakeholders (planners, management, drivers, and users). The findings highlight the need for improved universal accessibility, the provision of easy-to-understand travel information, ergonomic seat designs, and the use of electric vehicles with large battery capacities. The layout development begins by setting a capacity of 10–12 passengers, with all seats facing forward to allow passengers to enjoy the panoramic views. Furthermore, the entrance, circulation space, priority areas, and luggage compartments are designed based on human factors. The visual concept is inspired by Jalak Bali (Leucopsar rothschildi), adapting its dominant white color, blue accents, and dark elements on the wings and tail to present a modern shuttle that aligns with Bali's tourism identity.
