Judul: Komposisi Kimia, Asam Amino, Mineral dan Residu Logam Berat (Hg, Pb) Kupang Merah (Musculista senhausia) Segar dan Rebus
Abstrak: The red kupang (Musculista senhausia) is that many bivalves living on the East Coast Surabaya, East Java. Processing is done by boiling. The purpose of this study was to determine the yield, chemical composition, amino acids, minerals, and heavy metal residues (Pb, Hg) fresh and boiled mussel. Analysis of chemical composition include moisture content, ash, protein, and fat. Amino acid analysis by HPLC, minerals and heavy metals by AAS and phosphorus by spectrophotometer. The yield of meat and the shells of mussels decreased after boiling. The chemical composition of mussels decreased after boiling water levels fell 6.09%, 2.25% ash, 1.39% protein, 0.42% fat, and carbohydrate increased 4.07%. Analysis of amino acids produces 9 essential amino acids and 8 non-essential amino acids in fresh and boiled mussels. Amino acids decreased after boiling. Analysis of macro minerals produce minerals (Ca, Mg, K, P, and Na) and micro minerals (Co, Cu, Fe, Mn, Se, and Zn) and heavy metal Hg and Pb in mussels fresh and boiled. Mineral Ca, Mg, K, P, Na, Cu down, while Co, Fe, Mn and Zn ride. Heavy metals Pb decreased, Hg and Se was not detected.

Judul: Kadar Asam Lemak dan Kolesterol Kupang Merah (Musculista senhausia) Segar dan Rebus
Abstrak: Kupang merah (Musculista senhausia) consumed by many people of Surabaya area by boiling however information on the nutritional content changes due to processing kupang merah still a little. The purpose of this study was to determine the proximate , fatty acid and cholesterol of fresh and boiled kupang merah. The method used for proximate analysis by AOAC , fatty acids by GC, and cholesterol by Liebermann - Buchard . Fresh kupang has a moisture content 81.57% , ash 10.11% , 25.58% fat and protein 62.99%, while the boiled, water content is 75.48 % , ash 7.86% , 25.16% fat and protein 61.29%, fatty acids detected is SAFA 38.71% (fresh) and 37.31% (boiled), MUFA 8.13% (fresh) and 8.02% (boiled), PUFA 10.31% (fresh) and 8.77% (boiled), cholesterol content amounted to 102.57 mg/100 gram of fresh and boiled at 100.97 mg/100 gram . Boiling had a effect moisture content, ash, fat, protein, fatty acids and cholesterol.

Judul: A Continuous Vaccination Strategy in the SVIR Epidemic Model
Abstrak: Vaccination is conducted to minimize the spread of a disease. The vaccination is usually done several times within a fixed time interval. In the SVIR model, it is assumed that individuals do not get immediate immunity following a vaccination program. So according to process of vaccination on SVIR model, there are two strategies, i.e. the continuous vaccination strategy (CVS) and the pulse vaccination strategy (PVS). In this study, only the CVS strategy in epidemic model SVIR is considered. Results of the study indicate that dynamics of the CVS system depends on the basic reproductive number. If the basic reproductive number is less than one, then the disease-free fixed point is asymptotically stable. It means that the disease will eventually disappear from the population. Conversely, if the basic reproductive number is greater than one, then the endemic fixed point is asymptotically stable, which means that the disease will remain exist in the population. Simulation result shows that the vaccination would minimize the spread of disease by reducing the basic reproductive number. If the time for the vaccinated recipients to obtain the immunity, as well as a possibility of vaccinated recipients to be infected are neglected, then the disease will be eradicated. This condition is called an over-evaluating effect of vaccination.
