Abstract

Oral health hygiene constitutes one of public health problems that require comprehensive management due to its wide dimension. The lack of Calcium will hinder the process of teeth calcification and slow down the dental maturity. Low dental quality will lead the dental carries. Calcium is highest number of mineral in the human body. It will be obtained only from food, and the lack of it in the body will cause dental carries. This research is  an explanatory research with survey method and cross sectional approach. The total number of respondents is one hundred (100) students of grade 4 and 5 in the elementary school. The variables of the research include calcium intake during 3 x 24 hours, the frequency of eating high calcium food, frequency of eating carriogenic food, frequency, of tooth brushing, and the severity of the dental carries. The result of the research shows all ,students .suffer the deficiency of calcium (97% severaly lack of calcium, 1% moderately lack of calciurn, and 2 % lack of the calcium). Most of the students  (40%)  suffer dental carries of tight level. The result of rank Spearman test shows there is not correlation between calcium intake and food and beverage and the severity of dental carries (p=0,185). There is no correlation between frequency of eating high calcium food and the severity of dental carries (p=0,527). There is no correlation between frequency of tooth brushing and the severity of dental carries (p=0,495). Keyword : calcium intake, frequency of tooth brushing, severity of the dental carries

Abstract

Plant oil is one of the potential plant resources as hidro carbon or energy source in Indonesia. Nevertheless, the oil can nol be used automatically because of having high viscosity, lower octan number, free fat, lower volatility, gum, and higher residue if it is used as ready to use fuel. There fore it has to be changed to another form, that is, to be alkil ester ( biodiesel ).Biodiesel usage still uses solar fuel as mixture. In this research, it is found that performance dffirence between solar and biodisel and biodiesel use usage.fully.Diesel machine performance which wants to be researched is machine torsion generated by diesel machine using solar fuel and resulted by diesel machine by using different fuel.As preliminary study, testing used in injection system diesel machine is when machine in stationer or netral condition, and diesel fuel used is biodisel made of jarak pagar oil.Ester oil usage as biodiesel fuel is based on temporary prediction that biodiesel with jarctk pagar oil fuel does not need solar fuel mixture and need diesel machine modification.Keywords : Biodisel, Diesel Machine, and Machine Torsion.
