Abstract

Gmelina is a fast growing species that has high sufficient economy value and useful as medicinal plant. Propagation of gmelina by tissue culture has not been widely applied in Indonesia. This study aims to analize the effect of explant types and sterilization methods on the success of gmelina initiation. Treatments used in this study are explant types (apical shoot and leaf) and four sterilization methods (B1-B4) using detergent, tween 80, fungicide, bactericide, NaOCl, and HgCl2. All sterilization methods can produce 6‒19% sterile gmelina shoot culture, but has not succeded producing sterile gmelina leaf culture. Contamination by fungi and bacteria is the main cause of failed gmelina shoot and leaf culture initiation. In general, sterilization methods used in this study has succeeded in eliminating microbes on the explant’s surface, but has not succeeded in eliminating microbes inside the explant.

Abstract

Sungai Buluh Peat Protection Forest (HLG) is a peat protected area in Jambi that still natural and characterized by a high degree of vegetation density. This study aimed to estimate vegetation density using the Normalized Difference Vegetation Index (NDVI), estimate biomass and carbon stock along with fire hazard levels, and analyze the relationship between NDVI, vegetation diversity, and carbon reserves in HLG Sungai Buluh. The methods used include vegetation analysis, carbon estimation using allometric and destructive testing for seedlings and understory plants, fire hazard level estimation using land cover scoring and NDVI values. The result showed NDVI was categorized into three classes, nemely class 1 (-0,015 – 0,369), class 2 (0,369 – 0,438), class 3 (0,438 – 0,633). The most families found were Lauraceae, Dipterocarpaceae, and Myrtaceae. The average biomass and carbon stock obtained were 191,26 tons/ha and 89,90 tons C/ha, respectively. Fire hazard levels in all classes were found to be high. Carbon stock strongly correlated with LBDS (r = 98,2%). The NDVI value strongly correlated with the number of species.

Abstract

Mangrove ecosystems are essential for maintaining coastal ecological stability, yet they remain highly vulnerable to degradation due to increasing anthropogenic pressures. Rehabilitation efforts are a strategic step in restoring the ecological functions of these areas. This study was conducted to evaluate mangrove planting through growth parameters and to analyze the effect of planting distance on the growth of 11-month-old Rhizophora apiculata at a rehabilitation site in Purworejo Village, East Lampung. The survival rate at a planting distance of 1×1 m (95%) and 2×2 m (85%) showed good results, while at a planting distance of 1×2 m (68.3%) showed less favorable results. The stem height measurements indicated that the highest average was at a planting distance of 1×1 m (41.9 cm), followed by 2×2 m (36.7 cm), and 1×2 m (27.2 cm). In contrast, the diameter measurements showed that the largest average was at a planting distance of 1×1 m (1.17 cm), 2×2 m (1.10 cm), and 1×2 m (0.84 cm). Analysis of variance shows that the appropriate planting distance arrangement can improve the efficiency of space utilization and nutrient availability, as well as contribute to the structural growth of mangroves in the early phase.

Abstract

Perkebunan Bangelan PTPN I Regional 5 terletak di Desa Bangelan, tepatnya di Kecamatan Wonosari, Kabupaten Malang, Jawa Timur. Total luas areal konsesi Perkebunan Bangelan adalah 883,20 hektare, yang terdiri dari dua divisi perkebunan: Afdeling Besaran dan Afdeling Kampung Baru. Akibat perubahan iklim, Perkebunan Bangelan mengalami penurunan produksi kopi. Penyebab penurunan ini antara lain terganggunya sistem pembungaan akibat perubahan iklim yang tidak terjadi, serangan hama yang menyerang tanaman kopi, serta serangan gulma yang menyerap unsur hara sehingga terjadi persaingan antara tanaman kopi utama dengan gulma. Tujuan penelitian ini adalah menganalisis keanekaragaman vegetasi dalam sistem agroforestri kopi dan mengestimasi cadangan karbon pada berbagai pola agroforestri. Metode yang digunakan dalam penelitian ini adalah purposive sampling, berdasarkan tegakan agroforestri yang representatif. Sebanyak 27 petak dibuat dengan ukuran masing-masing 20 m x 20 m. Petak-petak tersebut tersebar pada tiga petak per tahun tanam, dengan luas total 1,08 ha. Kombinasi dominan pada sistem agroforestri yang diterapkan Kebun Bangelan dalam penelitian ini adalah campuran tanaman sengon, jabon, lamtoro, dan kopi Robusta. Salah satu tujuan pola tanam ini adalah untuk mengatur intensitas cahaya matahari yang masuk, yang oleh pengelola Bangelan disebut sebagai metode "tabur bintang". Jenis tanaman yang dominan untuk semua kelas semai, tiang, pancang, dan pohon adalah Leucaena leucocephala dan Coffea Robusta. Rata-rata stok karbon sebesar 21,86 ton, dan total stok karbon sebesar 196,74 ton. Total stok karbon tertinggi sebesar 29,24 ton, yaitu pada tahun tanam 1935. Pola agroforestri yang memadukan beragam jenis naungan dengan kerapatan tajuk terbukti paling efektif dalam mendukung keanekaragaman hayati dan meningkatkan penyerapan karbon.
