Judul: Hubungan perilaku hidup bersih dan sehat, konsumsi pangan, status anemia dan prestasi belajar pada remaja putri smpn 27 di Kelurahan Sumur Batu Bantar Gebang Bekasi
Abstrak: This study was aimed to analyze the relationship between clean and healthy behaviour, food consumption, anaemia status and learning achievement of female students of SMPN 27 Sumur Batu Village Bantar Gebang Bekasi. This research was a cross sectional study. The number of samples were 90 female students aged 13-15 years old. This research used semiquantitative food frequency questionnaire and anaemia status with hemoglobin level. The result indicated that clean and healthy behaviour of the female was in good category (81.1%). A large number of female were in normal anaemia status (84.5%) while the rest was anaemia (15.5%). Majority of the female had normal nutritional status (73.3%). The food habit was good (57.8%). Based on semiquantitative food consumption frequency, there was still lack of food consumption in the female. Largely, learning achievement of the female students classified in good category were 59 students (66%). Spearman’s correlation showed there’s no relationship between clean and healthy behaviour, food consumption, anaemia status and learning achievement (p>0.05).

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.
