Any deficiency of carotenoid in goldfish’ feeds can fade the color of the fish (Carassius auratus), especially in aquarium condition. The aim of this study was to explore other sources of carotenoid which is to replace the synthetic carotenoid already used. The fish were fed with different types of feed i.e. those without carotenoid source (A), those with synthetic astaxanthin (synthetic carotenoid) (B), Haematococcus pluvialis meal (C), and marigold petal meal (D). Lightness (L), chroma (C), hue (H), and the content of total carotenoids in the skin of fish were analyzed. The result showed that lightness was not significantly different among treatments. The best value of chroma was 35.59% (D), significantly different from those with other treatments and followed by 25.25% (B), 20.36% (C), and 19.98% (A). The highest content of total carotenoid in the skin was derived from B (59.55mg/kg), followed by D (24.79mg/kg), C (6.84mg/kg), and A (5.37mg/kg). This study suggests that marigold petal can be used as an alternative natural carotenoid source replacing synthetic carotenoid.

A hybrid model of Probabilistic Neural Network and Fuzzy C-Means has been developed. The model has been applied using Mel Frequency Cepstrum Coefficients (MFCC) as feature extraction for identification. In addition to the natural voice, the effect of noise has also been taken into account. It has been shown that the model has good accuracy at 96% for voice without noise, 85.5% for voice with noise at the level of signal to noise ratio 30, and 60% for voice with noise at the level of signal to noise ratio 20. It has also been concluded that the clustering procedure using Fuzzy C-Means could improve the accuracy up to 96% for large number of training data.

Dengan disahkannya UU No.40/2004 tentang SJSN, salah satu upaya pemerintah adalah memberikan perlindungan kesehatan bagi seluruh rakyat Indonesia. Hal ini berdampak pada peningkatan belanja kesehatan publik. Kondisi ini sebaiknya diikuti dengan peningkatan pendapatan, sehingga dapat diperoleh sumber pem- biayaan yang berkesinambungan. Penelitian ini menyajikan besarnya elastisitas PDB per kapita regional pada pengeluaran kesehatan per kapita masyarakat di Indonesia. Studi ini menggunakan data panel dari 2007–2009 dan dibagi dalam dua cakupan analisis, yaitu: sebanyak 35 negara dan 33 provinsi di Indonesia. Penelitian ini menerapkan metode OLS dan Fixed Effect Model. Hasil penelitian menunjukkan bahwa elastisitas pendapatan pengeluaran kesehatan per kapita masyarakat sangat tinggi dan bisa ditafsirkan menjadi sangat sensitif terhadap perubahan pendapatan negara terutama untuk kasus Indonesia sehingga keberlanjutan rencana pembiayaan skema asuransi kesehatan masyarakat di bawah Sistem Jaminan Sosial Nasional cukup memprihatinkan.
