Abstract

Proyek pembangunan Hotel Azana Bandar Lampung merupakan proyek gedung berlantai 11 yang memiliki potensi risiko kecelakaan kerja tinggi. Identifikasi risiko dilakukan terhadap beberapa faktor, seperti kurang fokusnya pekerja, penggunaan alat berat, area proyek yang tidak bersih, dan rendahnya kesadaran penggunaan Alat Pelindung Diri (APD). Tujuan penelitian ini adalah untuk menganalisis risiko kecelakaan melalui identifikasi risiko, survei lapangan, penilaian tingkat kecelakaan (likelihood index dan severity index), serta penentuan peringkat risiko. Metode penelitian yang digunakan adalah kualitatif. Hasil penelitian menunjukkan bahwa risiko paling dominan adalah pekerja terjatuh dari ketinggian dengan likelihood index 21% dan severity index 64%, serta putusnya sling crane dengan likelihood index 7% dan severity index 61%. Analisis risiko menggunakan diagram Bow Tie mengungkap bahwa risiko pekerja terjatuh disebabkan oleh kecerobohan pekerja, tidak adanya alat pengaman, fasilitas yang tidak memadai, dan kebersihan lokasi yang buruk, dengan konsekuensi berupa luka ringan, luka berat, atau kematian. Sementara itu, risiko putusnya sling crane dipicu oleh usia alat yang sudah tua, kondisi sling tidak aman, kelebihan beban, cuaca ekstrem, kurang fokusnya operator, dan tidak adanya rambu pengaman, yang berakibat pada luka berat, kematian, atau kerusakan alat berat. Kontrol peristiwa dan faktor eskalasi juga dianalisis untuk memitigasi risiko yang mungkin terjadi.

Abstract

Simple Healthy Instant Homes (RISHA) was developed as a fast and affordable housing solution to reduce slum settlements and improve housing quality. However, optimal spatial planning and natural lighting are still needed to meet comfort and health standards. This research evaluates the suitability of spatial planning and natural lighting in RISHA housing in Kampung Deret Petogogan, focusing on type 18 and type 36 houses. The methods used include primary and secondary data collection and analysis based on the Housing and Settlement Development Guide and the Healthy Home Module. Evaluation of natural lighting using Dialux Evo 12.1 refers to SNI 03-2396-2001. The research results show that spatial planning suitability reaches 50% in type 18 houses and 53% in type 36 houses, classified as "quite suitable." The distribution of natural light only meets the standard of 50% in type 18 and 40% in type 36, with the multipurpose room and bathroom being the most affected. Improvements are needed in RISHA design to improve occupant comfort and health, such as optimizing openings and transparent materials to increase natural lighting. Further research is recommended to develop more adaptive design strategies for environmental conditions.

Abstract

The implementation of construction projects often faces delays that are difficult to avoid, as experienced in the construction of the City X Hospital Building, where there was a discrepancy between the initial plan and actual field implementation, resulting in a two-week delay in weekly progress. This study aims to analyze time and cost efficiency and compare the effectiveness of alternatives between extending working hours and adding labor using the Time Cost Trade Off method. This research is comparative, comparing the total cost and duration of the project for both acceleration alternatives. The total project cost under normal conditions was recorded at IDR 7,289,386,643.45 with a duration of 86 days until the completion of the third floor. The analysis shows that extending working hours by 1 to 4 hours resulted in costs of IDR 14,584,817,481; IDR 21,871,659,072; IDR 28,672,701,971; and IDR 34,564,808,294, with cost efficiency of –100.08%, –200.05%, –293.35%, and –374.18%, respectively. The project duration was reduced to 64, 50, 41, and 36 days, with time efficiency of 26%, 42%, 53%, and 58%. Meanwhile, the alternative of adding labor resulted in a total cost of IDR 13,660,989,499 with a cost efficiency of –87.41% and a project duration of 64 days (26% time efficiency). Based on these results, both extending working hours by one hour and adding labor showed the most efficient outcomes, but overall, adding labor was considered more optimal as it achieved the same acceleration with the lowest total cost.
