Abstract

The Solomon Sengon tree (Paraserienthes falcataria moluccana subsp. solomonensis) is one of the fast-growing tree species widely planted, particularly in Industrial Plantation Forests (HTI), due to its rapid growth and adaptability to various soil types. The wood characteristics of Solomon Sengon are highly suitable for industrial needs. To monitor plant development, including diameter and height growth, plant survival criteria and measurement techniques must be applied. Growth evaluation is necessary to assess the development of Solomon Sengon, to determine the success and challenges encountered, and to serve as a basis for the extension or return of forest management permits. The research was conducted at PT Rimba Tanaman Industri, located in the villages of Hajran, Olak Besar, and Jelutih, Batin XXIV Sub-district, Batanghari Regency, Jambi Province. The research site consists of old rubber plantations and secondary forests with alluvial soil conditions and significant water activity due to rainfall and tributary streams. The study took place from July to September 2024 using an exploratory survey method. Samples were collected based on tree age (1-year, 2-year, and 3-year-old trees) using a purposive sampling technique. Data were analyzed using analysis of variance (ANOVA) followed by multiple linear regression. The results from PT Rimba Tanaman Industri showed that the survival rate of Solomon Sengon trees at 1 year of age was 69.81%, at 2 years 74.77%, and at 3 years 89.18%, indicating a successful growth trend. Based on the analysis and multiple linear regression test, soil pH and organic carbon (C-organic) were found to significantly influence tree diameter growth across all observed tree clusters (A, B, C, and D) at each age level. Pohon sengon solomon (Paraserienthes falcataria moluccana subsp Solomonensis) merupakan salah satu spesies pohon yang banyak ditanami khususnya pada Hutan Tanaman Industri karena pertumbuhannya yang cepat dan kemampuan untuk bertahan hidup di berbagai jenis tanah. Karakteristik kayu sengon salomon sangat cocok untuk kebutuhan industri. Kriteria kehidupan tanaman dan teknik pengukurang perlu digunakan untuk mengetahui perkembangan tanaman termasuk pertumbuhan diameter dan tinggi. Untuk mengetahui pertumbuhan tanaman sengon salomon perlu dilakukan evaluasi pertumbuhan. Evaluasi dilakukan untuk mengetahui keberhasilan dan kendala yang dihadapi hingga sebagai dasar perpanjangan dan pengembalian izin tindakan dalam mengelola kawasan hutan. Penelitian dilakukan di PT Rimba Tanaman Industri yang berada di Desa Hajran, Olak Besar dan Jelutih Kec. Batin XXIV, Kab. Batanghari, Provinsi Jambi lokasi penelitian ini adalah perkebunan karet tua dan hutan belukar dengan kondisi tanah aluvial dengan banyak aktifitas air akibat hujan dan anak sungai. Penelitian dilakukan dari bulan Juli hingga September 2024. Penelitian ini menggunakan metode survei eksplorasi. Dilakukan pengambilan sampel umur tanaman 1 tahun, 2 tahun dan 3 tahun menggukan sistem purpisive sampling. Analisis sidik ragam digunakan dalam menganalisis data, kemudian dilakukan uji regresi linear berganda. Hasil penelitian yang dilakukan di PT Rimba Tanaman Industri presentase hidup tanaman sengon salomon pada umur tanaman 1 tahun adalah 69.81%, untuk umur 2 tahun 74.77%, sedangkan untuk umur 3 tahun 89.18%, hasil tersebut dapat dijelaskan berhasil. Berdasarkan hasil analisis dan uji regresi linear berganda pertumbuhan tanaman dengan variabel Ph dan C-Organik menjelaskan pengaruh yang signifikan dengan diameter tanaman terhadap seluruh kalster tanaman yaitu A,B,C dann D di setiap umur tanaman yang diamati
