Judul: Analisis Biologi Berbasis Deret Waktu Pada  Sampel Feces Monyet Ekor Panjang
Abstrak: Long-tailed macaques (Macaca fascicularis) are valuable in forensic laboratory tests due to their similarities to humans. This study analyzed biological changes in macaque fecal samples over 24 hours, highlighting the need for fresh samples for accurate diagnostics. Ten healthy macaque fecal samples were examined using macroscopic examination, fluorescence imaging, and protein content assessment via the Bradford method. Results showed no significant changes in color and size, but consistency decreased from 4 to 6-hours, then increased at 8-hours. Odour score decreased initially, then increased at 8-hours. The fluorescent particle number rose up to 4-hours, then gradually decreased from 6 to 24-hours. The highest fluorescent color intensity was at 8-hours, with the lowest at 16-hours. Fluorescent particle size significantly increased at 6-hours and decreased at 16-hours. The protein content significantly rose after 2-hours, remained stable until 20-hours, and then decreased by 24-hours. No correlation was found between protein content and macroscopic examination (color, consistency, odour, size). This study underscores the dynamic biological changes in macaque fecal samples over 24 hours and the importance of using fresh fecal for accurate diagnostics., Monyet ekor panjang (Macaca fascicularis) memiliki nilai penting dalam uji laboratorium forensik karena kesamaannya dengan manusia. Studi ini menganalisis perubahan biologis dalam sampel tinja monyet selama 24 jam, menekankan perlunya sampel segar untuk diagnosis yang akurat. Sepuluh sampel tinja monyet sehat diperiksa menggunakan pemeriksaan makroskopis, pencitraan fluoresensi, dan penilaian kandungan protein dengan metode Bradford. Hasil menunjukkan tidak ada perubahan signifikan dalam warna dan ukuran, tetapi konsistensi berkurang dari 4 hingga 6-jam, kemudian meningkat pada 8-jam. Skor bau berkurang pada awalnya, kemudian meningkat pada 8-jam. Jumlah partikel fluoresen naik hingga 4-jam, kemudian secara bertahap menurun dari 6 hingga 24-jam. Intensitas warna fluoresen tertinggi adalah pada 8-jam, dengan yang terendah pada 16-jam. Ukuran partikel fluoresen meningkat secara signifikan pada 6-jam dan menurun pada 16-jam. Kandungan protein naik secara signifikan setelah 2-jam, tetap stabil hingga 20-jam, dan kemudian menurun pada 24-jam. Tidak ditemukan korelasi antara kandungan protein dan pemeriksaan makroskopis (warna, konsistensi, bau, ukuran). Studi ini menekankan perubahan biologis dinamis dalam sampel tinja monyet selama 24 jam dan pentingnya menggunakan tinja segar untuk diagnosis yang akurat.

Abstrak: The aim of this research was to observe Macaque’s (Macaca fascicularis) blood and get information of the haematology. This research was done during four months with four times collected, at IndoAnilab, Taman Kencana, Bogor and were analysed in pathology and lipid laboratory of primate centre, Pusat Studi Satwa Primata (PSSP), Bogor. Macaca fascicularis were being fed with three kinds of diets. Two kinds were high energy diet with different composition, both with tallow but one with yolk egg and the other one with monkey chow. There were fifteen adult males M. fascicularis and every five monkeys got different maintenance. This research observed erythrocytes number (million/ml), haemoglobin concentration (g/dl), hematocrit value (%), Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH), Mean Corpuscular Haemoglobin Concentration (MCHC) the differentiations of leucocytes (eosinophil, neutrophil, basophil, lymphocyte and monocyte). The results of this research were high energy diet extremely significant (P<0.01) affected in erythrocytes number, haemoglobin concentration, hematocrit value, MCV and MCH. Periods nested in treatment extremely significant (P<0.01) affected in erythrocytes number, haemoglobin concentration, hematocrit value, MCHC and significant (P<0.05) affected in monocyte. Positive relationship was present between erythrocytes number, haemoglobin concentration and hematocrit value as well as MCV, MCH and MCHC. Negative relationship was present between lymphocyte and neutrophil. The highest influence showed in high energy diet with tallow and yolk egg.
