Abstract

Calliandra (Calliandra sp.) is a shrub with multiple benefits, including its use as firewood and as a high-protein livestock feed. Sengon (Paraserianthes falcataria) is a fast-growing tree species widely cultivated to support the timber industry. To enhance seedling growth and productivity, environmental manipulation through shading and fertilization is necessary. This study aims to evaluate the effects of shading and NPK fertilizer doses on the growth of Calliandra calothyrsus and Sengon seedlings in the context of industrial forest plantation management. Using a completely randomized design, this study tested four shading levels (no shading, 25%, 50%, and 75%) and four NPK fertilizer doses (0, 1, 2, and 3 g per seedling). Each treatment was repeated twice, resulting in a total of 248 seedlings per species. The observed variables included height, diameter, and leaf count. The results showed that Calliandra exhibited no significant differences in height growth across shading levels. However, the best growth was observed under 25% shading, with a height increase of 11.84 cm and a diameter of 1.55 mm, and at an NPK dose of 2 g, with a height of 10.75 cm and a diameter of 1.54 mm. Meanwhile, Sengon showed the best height growth under 75% shading with an NPK dose of 1 g per seedling. The optimal diameter growth for Calliandra was achieved under 25% shading with an NPK dose of 1 g, while Sengon exhibited the best diameter growth without shading and with an NPK dose of 3 g.

Abstract

The protected forest of Londerang Jambi is an area of hydrological unity with a surface area of 12.484 ha that is located in the district of Tanjung Timur and Muaro Jambi, which is surrounded by palm plantations and forest of industrial crops and 10 villages in the Districts of Tanjung Jabung Timur and Jambi. Based on the results of the Landsat 8 OLI image analysis and the SPOT 7 image interpretation by WWF Indonesia in 2015 that the Londerang Forest Protection Area (HLG) has an area of 12.848 Ha, currently the steep vegetation cover that canopies closely on the HLG Londerang remains only less than 10% of the area of HLG londerang due to forest fires in 2015. An attempt to overcome the situation has been made, one of them in the HLG Londerang being made an of the Hydrological Union of Mendahara-Sungai Batanghari which has been intervened by the Badan Restorasi Gambut (BRG). This effort was also carried out by the KIFC (Korea Indonesia Forest Center) by revegetating the blocks of land that had been burned in HLG Londerang. The planting has been carried out from the beginning of 2022 to December 2022. The species of plants planted among them are Pulai Rawa (Alstonia scholaris), Balangeran (Shorea balangeran), Gelam (Melaleuca leucadendron). In order to support the success of the revegetation, intensive maintenance is required, including the provision of soil fertilizers such as dolomite and NPK fertilizer. The research was conducted for seven months from May to December 2023 at HLG Londerang. Measuring fields are made with group random designs (RAK). The clustering is based on the difference in the height of the groundwater surface

Abstract

ABSTRACT A specific type of plant that yield high-value non-timber forest products (NTFPs) that can be traded in large quantities is agarwood. Considering increasing demand and possibility of extinction to the agarwood population in natural forests, cultivation of this kind is imperative. Microorganisms found in local bamboo shoots are useful as fertilizers to promote the growth of agarwood seedlings. This research aims to investigate the effect of different doses of MOL fertilizer on the growth of agarwood seedlings and to determine the optimal dose for enhancing seedling development. This study has a completely randomized design with five treatments: m1 (10 ml/l), m2 (20 ml/l), m3 (30 ml/l), m4 (40 ml/l) and m5 (50ml/l). The results demonstrated that agarwood seedlings were impacted by the dosage of bamboo shoot MOL fertilizer. The optimum growth response to the parameters of height, diameter, number of leaves and root dry weight was obtained when bamboo shoot MOL fertilizer was treated at a concentration of 20 ml/l.   Keywords: agarwood, bamboo shoots, local microorganisms   ABSTRAK Gaharu merupakan jenis tanaman penghasil hasil hutan bukan kayu (HHBK) bernilai tinggi yang menghasilkan produk-produk turunan yang dapat dipasarkan secara luas. Budidaya jenis ini sangat diperlukan, mengingat kebutuhan yang semakin tinggi, sementara populasi gaharu di hutan alam semakin terancam punah. Mikroorganisme local rebung bambu merupakan pupuk yang dapat membantu pertumbuhan bibit gaharu. penelitian ini bertujuan untuk mengetahui pengaruh dosis pupuk MOL rebung terhadap pertumbuhan bibit gaharu serta mendapatkan dosis terbaik dalam meningkatkan pertumbuhan bibit gaharu. Penelitian ini menggunakan rancangan acak lengkap dengan 5 perlakuan yaitu m1 (10 ml/l), m2 (20 ml/l), m3 (30 ml/l), m4 (40 ml/l) dan m5 (50ml/l). Hasil penelitian menunjukkan dosis pemberian pupuk MOL rebung bambu berpengaruh terhadap bibit gaharu. Perlakuan pupuk MOL rebung bambu dengan dosis 20 ml/l memberikan respon pertumbuhan terbaik terhadap parameter tinggi tanaman, diameter batang, jumlah daun, dan berat kering akar.   Katakunci: gaharu, mikroorganisme lokal, rebung bambu
