Judul: Pengaruh Imunomodulator Pemberian Antibiotika Enrofloksasin, Oksitetrasiklin, Dan Tilmikosin Terhadap Gambaran Ulas Darah Putih, Aktifitas Dan Kapasitas Fagositosis Sel Fagosit Peritoneum Ayam Broiler (Gauus Domesticus Strain Hybro).
Abstrak: The aim of this research is to evaluate the effect of enrojloxacin, oxytetracydin and tilmicosin on host immune system, especiauy on white blood ceus differentiation, phagocytic activity and capability from peritoneum jluids. Thirty two broiler chickens (three weeks old) were distributed into four different treatments, three groups of them were given antibiotics (enrojloxacin, oxytetracydin and tilmicosin) and one control (non medicated control). Treatments were set for 5 days using subcutaneous application with 24 hours interval. Preparation of blood slide were done 24 hours after the last treatment and before chauenged using a nonprotein A Staphylococcus aureus intra peritoneumly. Intra peritoneum jluid were harvested one hour after the chauenged by opening the abdomen and couected the jluid fouowed by fir:ation and staining using Giemsa. In this trial, au antibiotics treatments showed increased the number of heterophil and decreased of lymphocyte. In the other hand, the result also showed no Significant effect of monocyte, eosinophil and basophil number. Tilmicosin treated group could enhance the activity of phagocytic ceus. Statisticauy, au antibiotics treatments showed no significant effect of phagocytic capability between control and au antibiotics treatments.

Judul: Pengaruh antibiotika tilmikosin, enrofloksasin dan oksitetrasiklin terhadap gambaran ulas darah, aktivitas dan kapasitas fagositosis sel fagosit mencit
Abstrak: Penggunaan antibiotik dewasa ini sangat luas sekali, tidak hanya dalam bidang kedokteran manusia saja tapi juga kedokteran hewan. Penelitian ini bertujuan mengetahui pengaruh dari pemberian tilmikosin, enrofloksasin dan oksitetrasiklin terhadap gambaran ulas darah, aktivitas dan kapasitas fagositosis hewan mencit. Pemberian tilmikosin, enrofloksasin dan oksitetrasiklin mempengaruhi jumlah sel limfosit, monosit dan netrofil mencit pada gambaran ulas darah. Pemberian tilmikosin meningkatkan jumlah limfosit tetapi menurunkan monosit dan netrofil, sedangkan enrofloksasin dan oksitetrasiklin meningkatkan jumlah limfosit dan monosit tetapi menurunkan netrofil. Pada uji aktivitas dan kapasitas fagositosis antar kelompok perlakuan antibiotik tidak berbeda nyata (P>0,05), tetapi jika dibandingkan dengan kontrol aktivitas dan kapasitasnya berbeda nyata (P<0,05). Dari hasil penelitian menunjukan secara umum tilmikosin, enrofloksasin dan oksitetrasiklin menimbulkan efek imunomodulator, yaitu meningkatkan jumlah sel limfosit dan aktivitas serta kapasitas fagositosis sel fagosit mencit.

Judul: : Persamaan Tunggal sebagai Representasi Kurva Komposit
Abstrak: A mathematical method is introduced to represent a composite curve based on an extension of analytic geometry. The representation is given either with a single equation or with two equations, in the case of parametric representation. This method permits the representation of composite curves in similar manner to the conventional representation of non-composite curves. Some mathematical tools, including Heaviside unit step function and periodizer function, are used in the establishment of a single equation. In this paper, regular equations of regular and irregular polygon, as well as composite curves of two dimensions, are implemented using a computer algebraic system, Mathematica.
