<![CDATA[This study aimed to determine the effect of rearing system (intensive and free-range) and village location (Karanggintung, Karangcegak, and Datar) on the proximate quality (crude protein, crude fat, moisture, and ash content) of duck eggs in Sumbang Subdistrict, Banyumas Regency. A 2×3 factorial Completely Randomized Design (CRD) was used, consisting of six treatment combinations and three replications, giving 18 experimental units. Proximate data were analyzed using Analysis of Variance (ANOVA), followed by the Least Significant Difference (LSD) test for significant effects. Results showed that rearing system, location, and their interaction had a highly significant effect (P<0.01) on duck egg moisture content. The highest moisture content was recorded in the intensive system in Datar Village (65.73%), while the lowest was in the free-range system in Karanggintung Village (58.81%). In contrast, rearing system, location, and their interaction did not significantly affect crude protein, crude fat, or ash content (P> 0.05). These findings indicate that moisture content is the proximate parameter most responsive to rearing management and location, whereas the macronutrient quality of duck eggs remains relatively stable, giving farmers flexibility in choosing a rearing system; the free-range system is more suitable for the processed-egg industry because of its lower moisture content.]]>
