      Abstract
      Leaf litter has a positive influence on the physical and chemical properties of soil through the provision of organic matter on the soil surface. This study aimed to measure the decomposition rate of leaf litter, and analyze the relationship between site characteristics and environmental conditions on the decomposition rate in agroforestry systems areas. Vegetation analysis was carried out on 50 m x 50 m sample plots totalling 14 plots. In addition, decomposition rate analysis, site characteristics, climate, and correlation tests were carried out. The dominant tree species in agroforestry systems areas was Agathis dammara. The highest and lowest decomposition rates in agroforestry systems areas at Gunung Kendeng Resort were 0.57 g/day and 0.33 g/day, respectively. The correlation between decomposition rate and edaphic factors that had a positive correlation were pH, soil organic matter, organic carbon, and porosity, while soil temperature, soil respiration, and bulk density had a negative correlation. The correlation between decomposition rate and climatic factors that had a positive correlation was moisture, while air temperature and light intensity had a negative correlation.
       
      Serasah memiliki pengaruh yang positif terhadap sifat fisik dan kimia tanah melalui penyediaan bahan organik di permukaan tanah. Penelitian ini bertujuan untuk mengukur laju dekomposisi serasah daun, dan menganalisis hubungan karakteristik tapak dan kondisi lingkungan terhadap laju dekomposisi pada areal sistem agroforestri. Analisis vegetasi dilakukan pada plot contoh 50 m×50 m sebanyak 14 plot. Selain itu, dilakukan analisis laju dekomposisi, karakteristik tapak, dan klimatis, serta uji korelasi. Jenis pohon yang mendominasi pada areal sistem agroforestri adalah Agathis dammara. Laju dekomposisi tertinggi dan terendah pada areal dengan sistem agroforestri di Resort Gunung Kendeng secara berturut-turut sebesar 0,57 g/hari dan 0,33 g/hari. Hubungan korelasi laju dekomposisi dengan faktor edafis yang memiliki korelasi positif adalah pH, bahan organik tanah, C-Organik, dan porositas, sedangkan suhu tanah, respirasi tanah, dan bulk density memiliki korelasi negatif. Hubungan korelasi laju dekomposisi dengan faktor klimatis yang memiliki korelasi positif adalah kelembapan, sedangkan suhu udara dan intensitas cahaya memiliki korelasi negatif.
