Judul: Ekstrak Air Buah Belimbing Wuluh (Averrhoa bilimbi) sebagai Reduktor dalam Pembuatan Nanomagnetit
Abstrak: Citrate content of bilimbi fruit (Averrhoa bilimbi) is potential as a Fe3+ reductor in nanomagnetite synthesis through hydrothermal method. The purpose of this experiment was to synthesis nanomagnetite using FeCl3, urea, and water extract of the fruit by hydrothermal method. Some fruit samples were smashed using blender to give suspension and water extract. The suspension reacted with FeCl3 and urea by hydrothermal method at 200 oC for 12 hours did not formed nanomagnetite, while those reacted under the same treatment formed nanomagnetite. The filtrate gave crystal size of 27.06 nm, which was smaller than that synthesized using sodium citrate as a reducing agent. The synthesized nanomagnetite contained 7 ppm cobalt and the liquid of the synthesized magnetite contained 52% ammonium showing the decomposed urea during the synthesis. Based on the experiment, water extract of bilimbi fruit can be used in nanomagnetite synthesis.

Judul: Analisis Bifurkasi Fluxon pada Persambungan Josephson Bertipe Superkonduktor-Feromagnetik-Superkonduktor (S/F/S)
Abstrak: Dynamics for the Josephson junction of type S/F/S is different from ordinary Josephon junction, where on the junction is contained the addition of tribal sin 2φ which is the result of the second harmonic supercurrent on the Josephson junction of type S/F/S that is related to Shapiro Steps symptoms. Research has been done is analyze the fluxon bifurcation to determine the stability of the fluxon in a Josephson junction of type S/F/S. The analysis was done by using the approach of analytically dynamics system and assisted by numerical solution that uses the application ODE 45 on MATLAB. The result of the critical point and the bifurcation types which is obtained to show the normalized damping (β and ϳₑ) does not affect the change of fluxon stability at the limit of less than one. Parameter β only affects the type of critical point and bifurcation that occurs, if β = 0, for ϳₑ = 0 and ϳₑ = 0.4 the bifurcation occurs is a saddle-center, and if β = 0.5 the bifurcation is a saddle-focus. Parameter ϳₑ affects the amplitude on the generated fluxon oscillation, if ϳₑ = 0 the fluxon amplitude is very small, whereas if ϳₑ = 0.4 the amplitude is larger. In each case, the fluxon stability is affected by the first harmonic supercurrents which is different sign, those are when ϳ₁ < 0 the fluxon is always stable, whereas when ϳ₁ < 0 fluxon is unstable at first but it tends towards to the point of its stability.

Judul: Kandungan steroid dari beberapa spesies ikan laut dalam di perairan Barat Sumatera dan Selatan Jawa
Abstrak: Perikanan tangkap di Indonesia umumnya masih terbatas pada perairan pantai atau perairan dangkal yang merupakan daerah paparan benua dengan kedalaman yang kurang dari 100 m (Suman 2006). Meningkatnya penangkapan setiap tahun di daerah tersebut telah menimbulkan fenomena overfishing. Salah satu alternatif untuk membatasi hal tersebut yaitu dengan memanfaatkan perikanan laut dalam (kedalaman lebih dari 200 m) yang sampai sekarang belum terjamah pemanfaatannya secara optimal. Negara - negara lain seperti Australia dan Jepang telah mengembangkan perikanan laut dalamnya. Oleh karena itu Indonesia bekerjasama dengan Jepang melakukan riset perairan Indonesia di sekitar perairan barat Sumatera dan Selatan Jawa.

Judul: Dynamical System of Hepatitis B in Three Groups with Vaccination
Abstrak: The aim of this study is to modify the hepatitis B transmission model in three age groups involving vaccination from the model conducted by Zhoe and Zhang.The method used is to analyze the stability of the fixed point and its basic reproduction number (R_0). Performed stability analysis and numerical simulation to see population dynamics. Next, a sensitivity analysis of the parameters was carried out to see its effect on R_0. From the analysis obtained two fixed points, namely non-endemic and endemic fixed points. Non-endemic fixed points are locally asymptotically stable if R_0 <1 Meanwhile, the endemic fixed point is locally asymptotically stable if R_0 > 1. Hepatitis vaccination affects the number of susceptible population, because the more successful the vaccination, the smaller the number of susceptible populations so that the smaller the population will be infected.

Judul: Bifurkasi Hopf pada Model Siklus Bisnis Kaldor Kalecki tanpa dan dengan Waktu Tunda
Abstrak: Business cycle model is one of dynamical system models in economic. One of the business cycles model is Kaldor-Kalecki model. Kaldor-Kalecki business cycle model that is written in delayed defferential equations, is a business cycle model that involves gross product and capital stock of a company. In this paper Kaldor-Kalecki business cycle model is analyzed using both nondelay and delay in time of capital stock. By Taylor expansion for the time delayed model, an analysis of stability around the fixed points has been done. Furthermore, by using Hopf bifurcation theorem, it can be shown that there exists periodic orbits and limit cycle. In the nondelayed model, changing the parameter of goods market could lead to the occurrence of Hopf bifurcation and the existence of limit cycle. Similarly, for the delayed model, it has been shown that changing the time delay parameter may result in the occurrence of Hopf bifurcation and limit cycle.
