Abstract

ANALISIS KESEHATAN TEGAKAN SENGON SOLOMON (Falcataria mollucana (Miq) Berneby & Grime) PADA BEBERAPA KELAS UMUR DI PT RIMBA TANAMAN INDUSTRI Julian Nurdin1) Bambang Irawan2) Suci Ratna Puri3) 1)Mahasiswa Jurusan Kehutanan Fakultas Pertanian Universitas Jambi 2)Dosen Jurusan Kehutanan Fakultas Pertanian Universitas Jambi 3)Dosen Jurusan Kehutanan Fakultas Pertanian Universitas Jambi Email: juliannurdin13@gmail.com ABSTRACT PT Rimba Tanaman Industri has made Solomon Gum (Falcataria moluccana (Miq) Barneby & Grime) one of the commodities developed in its working area, as Solomon Gum has rapid growth, is easy to adapt, and has a relatively short lifespan of 5-7 years after planting. In addition, Solomon Gum can also ensure the availability of raw materials for the pulp and paper industry, as well as for carpentry and construction needs. Solomon Gum, with the scientific name Falcataria moluccana (Miq.) Barneby & Grime, is a type of plant from the Fabaceae family that grows rapidly (fast-growing). The Solomon Gum plant is easy to adapt to the environment, soil types, and silvicultural characteristics (Baskorowati, 2014). The Solomon Gum plant has significant economic value, as its wood can be used for construction materials, furniture, and raw materials for the pulp and paper industry. This research was conducted using the Purposive Sampling method. Purposive Sampling is used to assess the health of trees within the cluster plot, and observations with this method are made by obtaining data on the most prevalent diseases in certain trees. The creation of cluster plots was carried out in the age classes of 1-4 years at a research location covering 733.21 ha with a sampling intensity of 0.5%. KU1 (10 months) covers 194.1 ha with 2 cluster plots, KU2 (18 months) covers 281.91 ha with 3 cluster plots, KU3 (30 months) covers 175.7 ha with 2 cluster plots, and KU4 (41 months) covers 81.5 ha with 1 cluster plot. Data analysis using the Forest Health Monitoring (FHM) method aims to establish criteria for evaluating tree damage. This evaluation serves as a basis for calculating the damage index value using the weight code of the Damage Index Value (NIK). NIK is the final value used to assess tree damage based on damage level criteria. The index value is obtained by multiplying the index value weight of the type of damage, the location damage index weight, and the severity of damage index value weight. In the final calculation results, the NIK is determined (healthy class, light damage, moderate damage, and severe damage) (Nuhamara and Kasno, 2001). The research results indicate that the condition of the Solomon acacia stand (Falcataria mollucana (miq) Barneby & Grime) at PT Rimba Tanaman Industri is healthy with light damage. The most common type of damage encountered is branch breakage with KU 1 at 16.41%, KU 2 at 61.98%, KU 3 at 99.27%, and KU 4 at 40.37%. The condition of the Solomon acacia stand (Falcataria mollucana (miq) Barneby & Grime) at PT Rimba Tanaman Industri has a damage index value for the 1-year age class of 0.60 (healthy), for the 2-year age class of 2.48 (healthy), for the 3-year age class of 5.30 (light damage), and for the 4-year age class of 5.78 (light damage). The condition of the Solomon acacia stand (Falcataria mollucana (miq) Barneby & Grime) based on the Damage Index Value across all age classes is 3.54, which falls into the healthy category. Key words: Health Analysis, Sengon Solomon (Falcataria mollucana (Miq) Berneby & Grime), Forest Health Monitoring (FHM) ABSTRAK PT Rimba Tanaman Industri menjadikan Sengon solomon (Falcataria moluccana (Miq) Barneby & Grime) sebagai salah satu komoditas yang dikembangkan di wilayah kerjanya, karena sengon memiliki pertumbuhan yang cepat, mudah beradaptasi serta memiliki umur yang relatif singkat yaitu 5-7 tahun setelah tanam. Selain itu sengon juga bisa menjamin ketersediaan bahan baku bagi industri pulp dan kertas serta untuk keperluan kayu pertukangan maupun bangunan. Sengon solomon dengan nama latin yaitu Falcataria moluccana (Miq.) Barneby & Grime merupakan salah satu jenis tanaman dengan suku Fabaceae yang memiliki pertumbuhan yang cepat (fast growing). Tanaman sengon mudah beradaptasi terhadap lingkungan, jenis tanah serta karakteristik silvikultur (Baskorowati, 2014). Tanaman sengon memiliki nilai ekonomi yang cukup besar seperti kayu nya dapat digunakan untuk bahan baku kontruksi, perabotan dan bahan baku industri pulp kertas. Penelitian ini dilakukan dengan menggunakan metode Purposive Sampling. Purposive Sampling digunakan untuk menilai kesehatan pohon yang berada didalam klaster plot, pengamatan dengan metode ini dilakukan dengan memperoleh data penyakit paling banyak pada suatu pohon. Pembuatan klaster plot dilakukan pada kelas umur 1-4 tahun di lokasi penelitian seluas 733,21 ha dengan intensitas sampling 0,5%. KU1 (10 bulan) seluas 194,1 ha 2 klaster plot, KU2 (18 bulan) seluas 281,91 ha 3 klaster plot, KU3 (30 bulan) seluas 175,7 ha 2 klaster plot dan KU4 (41 bulan) seluas 81,5 ha 1 klaster plot. Analisis data menggunakan Metode Forest Health Monitoring (FHM) bertujuan untuk menetapkan evaluasi kriteria kerusakan pohon. Evaluasi tersebut dijadikan dasar untung menghitung nilai indeks kerusakan dengan menggunakan kode bobot Nilai Indeks Keruskan (NIK). NIK merupakan nilai akhir yang digunakan untuk menilai kerusakan pohon berdasarkan kriteria tingkat kerusakan pohon. Nilai indeks diperoleh dengan mengalikan bobot nilai indeks tipe kerusakan, bobot indeks lokasi kerusakan dan bobot nilai indeks tingkat keparahan kerusakan. Dalam hasil akhir perhitungan maka diketahui NIK (kelas sehat, kerusakan ringan, kerusakan sedang dan berat (Nuhamara dan Kasno, 2001). Hasil penelitian menyatakan bahwa kondisi tegakan sengon solomon (Falcataria mollucana (miq) Barneby & Grime) di PT Rimba Tanaman Industri yaitu sehat dan kerusakan ringan. Tipe kerusakan yang paling banyak dijumpai adalah yaitu patah cabang dengan KU 1 16,41%, KU 2 61,98%, KU 3 99,27% dan KU 4 40,37%. Kondisi tegakan sengon solomon (Falcataria mollucana (miq) Barneby & Grime) di PT Rimba Tanaman Industri memiliki nilai indeks kerusakan pada kelas umur 1 tahun yaitu 0.60 (sehat), kelas umur 2 tahun yaitu 2,48 (sehat), kelas umur 3 tahun yaitu 5,30 (kerusakan ringan) dan kelas umur 4 tahun yaitu 5,78 (kerusakan ringan). Kondisi tegakan Sengon Solomon (Falcataria mollucana (miq) Barneby & Grime) berdasarkan Nilai Indeks Kerusakan pada seluruh kelas umur yaitu 3,54 termasuk kategori sehat.
