Penilaian Kesehatan Pohon di Taman Kota 1 BSD Menggunakan Forest Health Monitoring dan Aplikasi i-Tree Eco

Abstract

Taman Kota 1 BSD merupakan salah satu RTH di Kota Tangerang Selatan. Tekanan lingkungan perkotaan menyebabkan pohon rentan mengalami kerusakan sehingga berdampak pada menurunnya fungsi fisiologis pohon dan jasa lingkungan yang dihasilkan. Penelitian bertujuan menilai tingkat kesehatan pohon, kondisi tajuk, serta menganalisis jasa lingkungan. Pengumpulan data dilakukan pada empat plot FHM secara purposive sampling. Data yang dikumpulkan meliputi spesies, diameter, tinggi, parameter kesehatan pohon, kondisi tajuk, dan koordinat pohon. Pengolahan data kesehatan pohon dan kondisi tajuk menggunakan metode FHM, sedangkan jasa lingkungan menggunakan i-Tree Eco, persamaan alometrik, dan persamaan fotosintesis. Seluruh data kemudian dianalisis secara deskriptif kuantitatif dan kualitatif. Hasil penelitian menunjukkan dominasi pohon sehat (61%), kerusakan ringan (35%), dan kerusakan sedang (4%). Kondisi tajuk didominasi nilai VCR 4 (44%) dengan kerapatan tegakan 86,96% (kategori rapat). Perhitungan i-Tree Eco menunjukkan simpanan karbon sebesar 14,17 ton/ha, serapan CO2 0,49 ton/ha/tahun, dan produksi O2 1,41 ton/ha/tahun.

Taman Kota 1 BSD is one of the green open spaces in South Tangerang City. Urban environmental pressures effected trees to be more susceptible to damage, which can reduce its physiological functions and ecosystem services. This study aims to assess tree health, crown condition, and analyzed ecosystem services. Data collection was conducted at four FHM plots using purposive sampling. The collected data included species, diameter, height, tree health parameters, crown condition, and tree coordinates. Tree health and crown condition data were processed using the FHM method, while ecosystem services were analyzed using i-Tree Eco, allometric equations, and photosynthesis equations. All data were subsequently analyzed using quantitative and qualitative descriptive methods. The results showed a dominance of healthy trees (61%), followed by light damage (35%) and moderate damage (4%). The crown condition was dominated by a VCR value of 4 (44%), with a stand density of 86.96% (dense category). Calculations using i-Tree Eco indicated a carbon storage of 14.17 tons/ha, CO2 sequestration of 0.49 tons/ha/year, and O2 production of 1.41 tons/ha/year.
