Abstract

The aim of this study was to identify the mold of salted flying fish (Hirundichthys oxycephalus) at pasar Bersehati Manado. The aim Manado this study was to identified the mold of salted Flying fish at pasar Bersehati Manado. These research was carried out chemical analysis and microbial analysis of salted fish in two steps which are the total plate colony and identified the species of mold. The chemical analysis was persentase of water content and pH. The result showed that the water content of the flying fish was 29.33–37.00% and pH was 7.24–7.37. And the result of the microbial test showed that total colony of mold was 7x102–13.1x103 CFU/gram and the spesies were Fusarium sp and Aspergillus sp.Keywords: flying fish, salted, microbial, Manado.

Abstract

The Ferry Ro-Ro 5000GT has three levels of car deck that are connected by internal ramps. Two issues that have to be paid attention during the operation of the internal ramp there are the strength capacity and the design fatigue life of the internal ramp structure. The purpose of the research is to determine the strength and fatigue life of the internal ramp construction. The method used the Finite Element Method using a static load by load case of point load at top girder and between girders. Results of the research detected the maximum stress value is in the load case of the point load (three sedan car) at between of the girder is 52.143 MPa with the fatigue life is 44.47 years with the load cycle is 7300000 cycle while the minimum stress value detected at the load case of the point load (two sedan cars) at top girder is 34.199 MPa with the fatigue life is 195.92 years with the load cycle is 50000000 cycle. For the safety factor, ramp construction 6.08 ~ 10.38. The safety factor value above is still in safe condition because the value is SF > 1.
