Abstract

Desain berbasis keandalan sering digunakan dalam perancangan struktur yang mempunyai ketidakpastian harga dari parameter, baik parameter kekuatan struktur maupun parameter beban operasional. Pendekatan desain berbasis keandalan lebih realistis dibanding dengan pendekatan faktor keamanan untuk mengakomodasi ketidakpastian tersebut. Salah satu metode untuk menghitung keandalan struktur yang efisien adalah metode Mean Value First Order Second Moment (MVFOSM). Dalam paper ini akan dibahas perkiraan umur lelah struktur kapal berbasis keandalan, khusunya pada sambungan pelat alas pada midship kapal. Dengan menyatakan keandalan sebagai fungsi waktu maka peluang aman dari struktur tersebut pada waktu tertentu dapat diketahui. Studi kasus diambil pada kapal tanker 17.500 DWT yang dioperasikan di perairan Masalembo. Akibat fabrikasi pada pelat alas kapal diasumsikan terjadi retak permukaan sedalam 0,5 mm. Dengan menggunakan metode MVFOSM didapat bahwa nilai keandalan kapal dengan nilai rentang tegangan (Ds) rata-rata sebesar 25,63 MPa dengan COV 0,416, dan tegangan rata-rata (smean)  sebesar 47,81 MPa, struktur kapal tanker dianggap cukup andal sampai tahun ke-18 dengan indeks keandalan 3,65 atau peluang aman sebesar 99,8%

Abstract

Background: ARI is one of the diseases with a fairly high mortality and mortality rate, the housing environment in particular is very influential on the immune system. Housing that is dirty, cramped, crowded, and does not have adequate clean water facilities will cause children to be often infected by germs that come from dirty places and eventually get various infectious diseases. Houses that do not have enough clean air flow and whose residents are often found in the kitchen accumulated in the house will be susceptible to ARI. Methods: The type of research uses a quantitative research design with a cross sectional study design with a total sample of 95 respondents. Results: There is a relationship between residential density, home environment and immunization with the incidence of ARI in children under five in the coastal area of ​​the working area of ​​the Kolono Health Center and Tumbujaya Health Center, Kolono District and East Kolono District, South Konawe Regency. Conclusion: Factors related to ARI in toddlers include residential density, home environment, and immunization.
