Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis which transmission is sputum less micro-discharge issued by an infected patient. The examination of tuberculosis in acid-resistant bacteria is recommended by WHO using the Ziehl Neelsen method. The objective of this study is to determine the differences in the way the preparations were examined for the number of acid-resistant bacteria. This research is a cross-sectional design laboratory experimental research. The study was conducted in June-July 2018. The examination was conducted microscopically using the Ziehl Neelsen method. The inspection procedure is performed on direct preparations and indirectly checked. The results of the study conducted showed that there was no significant difference in the number of acid-resistant bacteria (p-value = 0.758). It was concluded that the results of examining the number of positive acid-resistant bacteria in direct and indirect preparations examined did not affect the results of the number of bacteria on the microscopic examination of positive acid-resistant bacteria. It is recommended for further studies on the use of uniformed samples for the making of preparations using one of the samples at any time.

The availability of non-synthetic media from natural ingredients is needed to answer the needs in laboratories where the price of nutrient media is quite expensive and there are limited supplies of material ware houses. Cowpea (Vigna unguiculata L.) and pigeonpea (Cajanus cajan L.) are the local foods of people of NTT (East Nusa Tenggara) which have a high enough nutritional content which has the potential to be developed into cheap, easy and simple non-synthetic media in making. The purpose of this study was to determine whether the agar media contained nutrient from cowpea and pigeonpea water can be used as a alternative for nutrient agar for the growth of Escherchia coli and Staphylococcus aureus bacteria. This research is a true experiment with posttest-only control design. The growth rate of S. aureus bacteria on pigeonpea medium, cowpea medium, nutrient agar medium, were 164 CFU/mL (SD=3,13), 161 CFU/mL (SD=3,02) and 164 CFU/mL (SD=3,21), respectively. The average growth of E. coli on cowpea medium, pigeonpea medium, and nutrient agar control medium were 163 CFU/mL (SD=2,79), 167 CFU/mL (SD-2,63) and 164 CFU/mL (SD=2,75) respectively. Test results ANOVA between pigeonpea medium, cowpea medium and nutrient medium in order to obtain p value = 0.145 (p> 0.05) for the growth of E. coli bacteria and p value = 0.393 (p> 0.05) for growth S. aureus. It was concluded that there was no difference between the number of bacterial colonies of E. coli and S. aureus on three medium. The pigeonpea medium and cowpea can be used to grow and alternative nutrient agar in order to grow bacteria E. coli and S. aureus.
