Judul: Pengaruh Pemberian Ekstrak Etanol Rimpang Temu Putih (Curcuma zedoaria (Berg.) Roscoe) Terhadap Jumlah Dan Diferensiasi Leukosit Pada Kelinci Yang Diinduksi Tumor Dan Diterapi Dengan Operasi
Abstrak: The objective of this research was to observe the profile of rabbit leococytes which was induced by tumour and treated by combination of surgery (ovariohisterectomy and mastectomy) with ethanolic extract of zedoary rhizome (Curcurna zedoaria (Berg.) Roscoe): preventive; curative; preventive and curative. Twenty one rabbits were used in this research, divided into seven groups: negative control, preventive and curative of curcumin, positive control, surgery, preventive of ethanolic extract of zedoary rhizome, preventive and curative of ethanolic extract of zedoary rhizome, and curative of ethanolic extract of zedoary rhizome. The blood collection was done every week for 9 weeks. The tumour was induced on second quarter of mammary gland by n-methyl-nnitrosourea (MNU) every week for 3 weeks. The ethanolic extract of zedoary was given daily for 4 weeks (preventive; curative) and 8 weeks (preventive and curative). The surgery was done in the fifth week. The result showed that the total leucocyte, neutrophil (heterophil), eosinophil and basophil count increased before surgery. On the other hand, the total leucocyte, neutrophil and lymphocyte count decreased after the administration of ethanolic extract of zedoary rhizome.

Judul: Gambaran jumlah total dan diferensiasi leukosit sebelum dan sesudah mastektomi dan Ovarihisterektomi pada kelinci yang diinduksi tumor dan diobati temu putih (Curcuma zedoaria (Berg.) Roscoe)
Abstrak: The objective of this research is to find out the potency of zedoary rhizome extract on the total and differentiation of leucocytes of mammary glands tumor rabbit before and after surgey. Twelves females between 6-9 months old rabbit were divided into 4 groups. First group was a control, the second group was induced by n-methyl-n-nitrosourea (MNU), the third group was induced by MNU and treated by operation, and the fourth group was induced by MNU and treated by combination between operation and administration of extract of zedoary rhizome. MNU was given every week for 4 weeks and the next week was the surgery. Extract of zedoary rhizome was given every week after surgery for 5 weeks. The blood collection was done every week for 9 weeks. Blood were observe to count total and differentiation of leucocytes. The result showed that the leucocytes and lymphocytes increased in blood circulatory of group 1,2, and 4. The conclusion is the administration of zedoary rhizome extract can increased the immunity system by increasing of leucocytes and lymphocytes., Penelitian ini bertujuan untuk mengetahui pengaruh ekstrak rimpang temu putih terhadap gambaran jumlah total dan diferensiasi leukosit pada kelinci tumor kelenjar mammaria sebelum dan sesudah operasi. Dua belas ekor kelinci betina berumur 6-9 bulan dibagi ke dalam 4 kelompok perlakuan, kelompok kontrol, kelompok induksi n-metil-n-nitrosourea (MNU), kelompok induksi MNU + operasi dan kelompok induksi MNU + operasi + ekstrak temu putih. Induksi dilakukan selama 4 minggu dan minggu ke-5 kelinci dioperasi. Ekstrak temu putih diberikan selama 5 minggu sesudah operasi. Darah kelinci diambil setiap minggu selama 9 minggu. Darah diperiksa untuk dihitung jumlah total dan diferensiasi leukosit. Hasil pengamatan menunjukkan bahwa jumlah total leukosit dan limfosit meningkat di sirkulasi pada kelompok 1,2 dan 4. Dari pengamatan dapat disimpulkan bahwa pemberian ekstrak temu putih dapat meningkatkan sistem pertahanan tubuh melalui peningkatan jumlah total leukosit dan limfosit. Kata kunci : kelinci, leukosit, zedoaria.

Abstrak: An automatic detector of water level with sensor UGN3505 as detector of changes water level has been successfully be made for this research. Sensor UGN3505 is a hall effect sensor which works based on the large magnetic fields on the surface. The output voltage generated by the sensor without the influence of a magnetic field is 2,525 volts, the output voltage is different than it should be 0.025 volts is 2.50. This shows that the sensor is not completely free from magnetic field sources, there is still the effect of the Earth's magnetic field to the sensor. Sensor output voltage will increase, with increasing magnetic field on the surface of the sensor. As the central data processing equipment, used microcontroller ATmega16. The input of microcontroller is the changes output voltage of sensor than has been converted into digital data (internal ADC ATmega16) caused the changes of magnetic field. The digital data are readable by microcontroller be processed and displayed in the 16x2 LCD, LED indicator and buzzer. Programs created using software tools CVAVR with C + + language.
