    The development of composite materials can be combined with the test material to obtain a composite material properties such as strength, hardness, wear, and surface roughness. The surface roughness of polymeric materials and composites can be tested in many ways, ranging from tactile method (profile measurement), focus variation (area measurement), fringe projection (area measurement), confocal laser scanning microscope (area measurement), and several other methods. Varied roughness testing on the surface will be compared to obtain the most suitable testing method to obtain the roughness of hybrid composite and composite ceramic specimens. The method used in this study is literature review. For hybrid composite material will be less suitable when using tactile method because of hybrid composite having a lower surface hardness. Additionally hybrid composite has a porosity value greater than the ceramic composite. This causes hybrid composite is more rugged than ceramic composite. Therefore with greater porosity will be suitable when using the roughness measurement with a microscope device such as fringe projection (area measurement), and confocal laser scanning microscope (area measurement)

    Hull Inspection Productivity Measurement for a New Shipbuilding Project (Case Study of Bic 11.02 a New Shipbuilding Project)

    Hull construction process for a new shipbuilding project usualy consist of a set of stages. Starting from material identification, marking, cutting fabrication, assembly and testing. For many shipyard hull inspection activity and hull production stages are joined to simplify production progress monitoring. A 20% credit given for inspection activity. Inspection activities particulary for hull construction which consist of inspection and repair work. Schedule slip of a new shipbuilding is very potencial. This condition is met when man power allocation and work priority are not set properly. Therefore, a clear parameter which conduct with inspection productivity to production manager should be provided. This parameter could help production manager to determine priority of repair work. In this case, differences parameter between production that is using pane measurement and inspection that is using compartement measurement. These two different parameter could make difficulties, particulary when production manager want to know how much progess has been done. A new method to converting the two different parameter has become a topic of this pape

    High Speed Ship Total Resistance Calculation (an Empirical Study)

    High speed design studies became very intense studies. One of the subject that can be explore is obtaining total resistace. A high speed ship has four stages of condition when she operates. Starting from low speed condition until developent of dinamics lift force. These four states that happened on high speed ship when she cuise on her operational speed, make a specific consideration on predicting her total resistance. As high speed ship become more widely built and operate in Indonesia, the study of the state of art of high speed vessel especially for obtaining total resistance has became more challenging In this paper is foccused on proposing an applicative methods for high speed resistance calculation based on savitsky method. Result which obtained form empirical study is compared to numerical software. Result of this study shows that there are no significant differences between empirical method and result form software application. Considering of sea margin would be effective to made the empirical method would be applicable. There is a 128,0812 KN of total resistance using empirical method, by considering sea margine factor, and a 128,512 KN of total resistance resulted form software calculatio

    Birth weight can be a potential predictor for short-term and long-term health outcomes. Low birth weight can be an output from maternal malnutrition. Mothers' chronic energy malnutrition risk is detected by measuring maternal mid-upper arm circumference (MUAC). This study aimed to analyze the correlation of maternal MUAC with a baby's birth weight. This study was an analytic observational study that used secondary data from October 2021 to January 2022. Data were obtained from Tanjungsari Intergenerational Study Nutrition Working Group from 2014 to 2016. Subjects were 124 pairs of mother and baby who were recruited using total sampling. Data were analyzed using t-test and logistic regression. A significant association of maternal MUAC and the baby's birth weight (t (122) = 3.75, 95% CI 174.5, 564.0, p=0.000) was detected. Underweight (OR 23.3, 95% CI 2.6, 209.0, p=0.005), overweight, and obese (OR 0.05, 95% CI 0.01, 0.42, p=0.006) status was shown to have an association with MUAC. Education level and occupation status had no associations with MUAC. In conclusion, maternal MUAC is associated with baby's birth weight. The determinant factors of maternal MUAC were underweight, overweight, and obese status
