Abstract. The research was aimed to determine the effect of the addition of Azolla sp. on
physiological conditions, the kinetics of temperature, and the quality of compost which
includes carbon content, and compost organic matter. The method used was experimental with
A Completely Randomized Design (CRD). There were three treatments that were the addition
of Azolla sp. 0% (P0), 10% (P1), and 20% (P2). Each treatment was repeated 6 times, so that
the number of experimental unit was 18 mounds of compost. Variables measured were
temperature kinetics, levels of organic carbon and compost organic matter. Observations of
temperature were carried out on days 0, 4, 8, 12, 16, 20, 24 and 28 at 01.30 – 02.30 pm. The
carbon content and compost organic matter of the final compost product were analyzed in the
laboratory. Data on the kinetics of temperature were analyzed using Repeated Measure
Analysis of variance (RMA), while those of the levels of organic carbon and organic matter
compost were analyzed using Analysis of variance (ANOVA). The results of the variance
analysis showed a significant interaction (P < 0.05) between the treatment and the days of
observation on the kinetics of temperature. The highest temperature kinetics observed for P2
and P1 were achieved on day 4 (54.00˚C and 50.50˚C, respectively), while the highest
temperature for P0 was achieved on day 8 (50.33˚C). The temperature of P0, P1 and P2 ranged
27.17-50.33˚C; 28.17-50.50˚C and 30.00-54.00˚C, respectively. Least Significance Different
(LSD) results showed significant variations in temperature kinetics. Enrichment of compost
with Azolla sp had no significant effect (P > 0.05) on the levels of organic carbon and compost
organic matter
