An educational poster, likely displayed indoors on a light-colored wall, illustrates the "Proses Pembentukan TANAH" (Soil Formation Process) in Indonesian. The poster is divided into five main stages, depicted chronologically from left to right with numbered headers and distinct background colors. Stage 1, "PELAPUKAN BAHAN INDUK TANAH" (Weathering of Parent Material), shows bedrock (Batuan Induk) breaking down, influenced by "PENGARUH IKLIM" (Climate Influence) such as "Curah Hujan dan Suhu" (Rainfall and Temperature). Stage 2, "ORGANISME + B.ORG DUKUNG PELAPUKAN" (Organisms + Organic Matter Support Weathering), shows the accumulation of organic material and the initial formation of Horizon A. Stage 3, "LAPISAN DAN HORISON TERBENTUK" (Layers and Horizons Formed), illustrates the development of humus and the distinct A and B horizons through "Translokasi" (translocation). Stage 4, "PROSES INTERAKSI HARA TANAH DAN TANAMAN" (Process of Soil Nutrient and Plant Interaction), depicts a more developed soil profile with established plants. The fifth section, labeled "PEMANFAATAN TANAH PERTANIAN" (Agricultural Soil Utilization), highlights "PENGELOLAAN TANAH EROSI, TAMBANG DAN TIMBUNAN" (Soil Management Erosion, Mining, and Accumulation) and the potential for "DEGRADASI" (Degradation), showing a diminished soil profile. Below the main diagram, the poster lists factors for soil formation ("Pembentukan Tanah = fungsi dari:"), including climate, relief/topography, organisms, parent material, time, and soil management. It also details "HORISONISASI" (Horizonization), defining Horison A (Epipedon) with examples like Molik and Okhrik, Horison B (Horison Penciri) with examples like Argilik and Oksik, and Horison C (Batuan Induk/Parent Rock). The poster is attributed to "Kasuma Nugraha, 2020."
