This study aim was to determine technical production factors affecting payang fishery catch in Madura Strait. Research was conducted at Gili Ketapang village, Sumberasih subdistrict, Probolinggo District, East Java Province. It is center of payang fishing activities in Probolinggo. This research was conducted during January to May 2014. This study uses descriptive method method with survey research techniques. A data analysis tool is Cobb-Douglass analysis. Production factors of payang fisheries in Madura Strait (X) that allegedly affect on production or catch in tones/year (Y) are experience (years), amount of catch trip (trip), amount of fuel required (Rp) and payang pockets length (m). Determination Coefficient (R2) obtained from analysis is 91.6%. It can be interpreted that increase or decrease amount of payang catch in Madura Strait that affected by production factors investigated are 91.6%, while 8.4% is determined by factors or other variables that not examined. Analysis results with F test values show Fcount = 68.008. This value is greater than Ftab = 2.690. This shows that all technical production factors significantly affect on payang catch. Meanwhile, effect of production factors on payang production is known by Student t test. Test results show that partially fishing experience (X1), amount of arrests trip (X2) and pocket payang length (X4) have significant direct effect on payang production at 95% confidence level. Analysis result of Cobb Douglas function obtains regression equation of payang production factor in Madura Strait, namely: Y =-8,580 + 0,454 X1 + 1,147 X2 + 0,239 X3 + 0,344 X4. To obtain optimum production, fishermen must intensify payang catch at peak fishing season and increases the size of payang pocket. Further research should include variable production factors outside these study variables in order to determine ratio of payang catch production.
