Abstract: The physical and chemical properties of compost are important in supporting agricultural development. The physical and chemical properties of compost are greatly influenced by the basic ingredients for making compost. Apart from that, to produce quality compost fertilizer, decomposer bacteria are needed. This research aims to determine the role of decomposers in accelerating fertilizer decomposition, and to determine the physical and chemical content of compost fertilizer from waste palm fronds and leaves with the addition of cow dung fertilizer. This research was carried out from May to July 2023, located in Kembang Janggut District, Kutai Kertanegara Regency, East Kalimantan Province. The research was structured with 2 treatments, namely P1 and P2. The variables observed include composting time, physical properties of the compost (temperature, color, smell, texture), and chemical properties of the compost (total N, total P, total K, total C, C/N ratio). The observation data was analyzed descriptively and compared with the fertilizer quality standards of the Republic of Indonesia Ministry of Agriculture number 261/Permentan/SR.310/4/2019. The results of the research showed that the length of time for composting palm oil leaf sheath and leaves waste in treatment P1 was faster, namely 42 days, while in treatment P2 it was 45 days. Physical data on compost fertilizer shows that the temperature in treatment P1 on day 39 and in treatment P2 on day 42 the temperature has begun to fall. and was declared ripe, followed by a black color change and no smell. The results of compost nutrient analysis in treatment P1 were N total (0.042%), P total (0.069%), K total (0.067), C-organic (29.176), C/N ratio (69.765%), while in treatment P2 it was N total (1.202%), P total (0.319%), K 0.096%, C-organic (28.314%), C/N ratio (23.591%). These results indicate that the P1 and P2 treatments for observing organic C and the C/N ratio have fulfilled the quality requirements for solid organic fertilizers in the Ministry of Agriculture Regulation for compost requirements number 261/MOA/SR.310/4/2019.
