Keywords : developer, density, pH (acidity), NaOH, Na 2 CO 3. In this study aims to determine the pH value of the liquid developer and image density with the addition of NaOH and Na 2 CO 3 as well as a result of the use of the developer fluid. This research is done by washing the film on the object stepwedge used the same exposure factors namely 60 kV tube voltage, time and tube current of 8 mAs. After that film development using weak developer liquid was done. To increase developer liquid’s acidity, two part of processing using 5 grams addition of NaOH and Na 2 CO 3 on each part were done. On the first film the process was carried out by adding 5 grams of NaOH and Na 2 CO 3 to each film on the first part of liquid. The same procedure applied using the Na 2 CO 3. The film image density then measured by densoitometer. Result of research shows that adding NaOH and Na 2 CO 3 to developer liquid can increase the acidity and density of film images. Adding NaOH resulted in the highest acidity level of 12,01 with the highest density level of 0,94, while adding Na 2 CO 3 resulted in the highest acidity level of 10,49 with the highest density level of 0,93.
