      Abstract
      Model arsitektur pohon merupakan bentuk tiga dimensi dari bangunan suatu pohon. Bentuk/model arsitektur ini disusun berdasarkan bagian-bagian tanaman yang berada di atas tanah seperti pola pertumbuhan batang, percabangan, ukuran, bentuk serta posisi daun dan bunga. Model arsitektur suatu pohon mempengaruhi nilai aliran batang (stemflow) dan curahan tajuk (through fall), selanjutnya aliran batang dan curahan tajuk menentukan besarnya nilai aliran permukaan dan erosi tanah yang akan menimbulkan kerusakan pada tanah tersebut. Erosi tanah, sejauh ini merupakan bentuk yang paling banyak menyebabkan degradasi atau kerusakan tanah. Pada daerah tropis seperti Indonesia, air merupakan penyebab utama terjadinya erosi. Model arsitektur pohon diperkirakan memiliki peranan yang sangat penting terkait dengan keberadaan pohon tersebut dalam konservasi tanah dan air pada suatu ekositem di daerah tropis.
       
      Agathis dammara L.C. Richard is plant that shaded Coffea arabica L. in the Pengelolaan Hutan Bersama Masyarakat (PHMB)'s ecosystem in South Bandung. Agathis dammara L.C. Richard with Massart's architecture has the contribution toward the soil and water conservation within its ecosystem. The purposes of this research are: 1) Determining the parameter’s scale of soil and water conservation (rain fall, stem flow, through fall, surface run-off and erosion) in the PHBM’s ecosystem, 2) determining the correlation between the parameter of soil and water conservation in PHMB's ecosystem, 3) determining the role of plant architecture model Massart of Agathis dammara L.C. Richard toward soil and water conservation in PHBM’s ecosystem. The results shows the scale of rain fall, stem flow, through fall, surface run-off, and erosion of Massart architecture model of Agathis dammara L.C.Richard in a row are 981.6 mm, 17.905 mm, 515.86 mm, 45.49 mm, and 5.314 ton/ha/year. Biplot Analysis shows the positive correlation among the parameter of rain fall, stem flow, through fall, surface runoff and erosion. Therefore, it can be concluded that the Massart’s Architecture model for Agathis dammara L.C. Richard is good for supporting the soil and water conservation of PHBM’s ecosystem where stem flow is the most closely related to the erosion.
