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

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.

Abstract

ABSTRACT                 The number of people in the world continues to increase causing a soaring energy needs and wood needs. The way to get raw materials for renewable energy is to use energy wood from leguminous species, such as red calliandra (Calliandra calothyrsus Meissn.). The benefits of calliandra are forage for livestock, erosion control, conservation and reclamation, and raw material for wood pellets. The success of generative calliandra cultivation is determined by many factors, one of which is the planting media. Planting media used in cultivation do not all contain sufficient nutrients, such as ultisol soil which has problems such as soil acidity, and low macro nutrients and low C-organic, to overcome these problems the addition of organic matter in the from of cow manure. The purpose of this study was to analyse the effect of cow manure and the best dose of cow manure on the growth of red calliandra seedlings. Methods the study used a CRD single-factor with 5 levels of cow manure treatment (k0 without fertilizer, k1=50 g/polybag, k2=100 g/polybag, k3=150 g/polybag, k4=200 g/polybag) repeated 6 times so as to obtain 30 experimental units, consisting of 5 seedlings so that a total of 150 seedlings. The observation variables were height, diameter, number of leaves, root and crown dry weight. The results showed that the application of cow manure had a significant effect on the growth of red calliandra seedlings, especially on the variables of height, number of leaves, and root dry weight but had no significant effect on the variables of diameter and crown dry weight. The application of cow manure at a dose of 100 g/polybag is the best dose to support the growth of red calliandra (Calliandra calothyrsus Meissn.) seedlings.   Key words: red calliandra, cow manure, ultisol.   ABSTRAK             Jumlah penduduk di dunia terus mengalami peningkatan menyebabkan melonjaknya kebutuhan energi maupun kebutuhan kayu. Cara untuk mendapatkan bahan baku Energi Terbarukan (EBT) adalah menggunakan kayu energi dari jenis leguminosa, seperti tanaman kaliandra merah (Calliandra calothyrsus Meissn.). Manfaat kaliandra yaitu hijauan makan ternak, pengontrol erosi, konservasi dan reklamasi, serta bahan baku wood pellet. Keberhasilan budidaya kaliandra secara generatif ditentukan dari banyak faktor salah satunya yaitu media tanam. Media tanam yang digunakan dalam budidaya tidak semua mengandung unsur hara yang cukup, seperti tanah ultisol yang memiliki permasalahan seperti kemasaman tanah, dan unsur hara makro yang rendah serta C-organik yang rendah, untuk mengatasi permasalahan tersebut dilakukan penambahan bahan organik berupa pupuk kandang sapi. Tujuan penelitian ini untuk menganalisis pengaruh pupuk kandang sapi dan dosis terbaik pada pemberian pupuk kandang sapi terhadap pertumbuhan bibit kaliandra merah. Metode penelitian menggunakan RAL faktor tunggal dengan 5 taraf perlakuan pupuk kandang sapi (k0=tanpa pupuk, k1=50 g/polybag, k2=100 g/polybag, k3=150 g/polybag, k4=200 g/polybag) diulang 6 kali sehingga diperoleh 30 satuan percobaan, terdiri dari 5 bibit sehingga total 150 bibit. Variabel pengamatan berupa pertambahan tinggi, diameter, jumlah daun, berat kering akar dan tajuk. Hasil penelitian menunjukkan bahwa pemberian pupuk kandang sapi berpengaruh nyata terhadap pertumbuhan bibit kaliandra merah terutama pada variabel tinggi, jumlah daun, dan berat kering akar namun tidak berpengaruh nyata pada variabel diameter dan berat kering tajuk. Pemberian pupuk kandang sapi dengan dosis 100 g/polybag merupakan dosis terbaik untuk menunjang pertumbuhan bibit kaliandra merah (Calliandra calothyrsus Meissn.).   Kata kunci: kaliandra merah, pupuk kandang sapi, ultisol.

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

Gold mining activities degrade soil physical and chemical properties, increasing compaction, reducing drainage and aeration, lowering productivity, and limiting plant growth. This study evaluated soil fertility, physical and chemical characteristics of ex-illegal gold mining land, and identified arbuscular mycorrhizal fungi (AMF) species and ammonifying bacteria associated with pioneer plants used for phytoremediation. The results showed that high clay content limited water and nutrient infiltration. The average clay content increased from 42.41% in 2019 to 45.12% in 2021. Soil pH (H₂O and KCl) was acidic, ranging from 4.20 to 5.92. Organic carbon (0.96–1.87%) and total nitrogen (0.11–0.26%) were classified as low, indicating poor soil fertility. Among pioneer plants, Melastoma malabathricum showed the highest AMF spore abundance, with 37, 30, and 29 spores per 50 g of soil in 2019, 2020, and 2021, respectively. The highest population of ammonifying bacteria was found in the 2021, with a count of 46.3 x 105 individuals per gram of soil. This study aims to identify the interactions between AMF and ammonifying bacteria associated with pioneer plants to support phytoremediation activities on ex-illegal gold mining land.

Abstract

ABSTRACT Leaf roller pest Strepsicrates sp. is a major threat to Eucalyptus pellita in Industrial Plantation Forests, reducing leaf area available for photosynthesis and consequently inhibiting plant growth. Chemical insecticides have been widely used to control this pest; however, variations in insecticide type and dosage often show limited effectiveness while posing environmental risks and increasing the potential for pest resistance. Therefore, integrated pest management using biological control and refugia plants such as Turnera sp., which provide nectar and pollen resources for natural enemies, has been proposed as an environmentally friendly alternative. This study aimed to evaluate the effect of different planting densities of Turnera sp. on the population and damage caused by leaf roller pests. The research was conducted at PT. Wirakarya Sakti using a systematic sampling method with 8 × 8 m² observation plots. Four treatments were applied: 0% (control), 25%, 50%, and 75% Turnera sp. planting density. Observed parameters included attack intensity, attack percentage, and pest population density. It was hypothesized that increasing the density of Turnera sp. would significantly reduce pest populations and attack levels. However, the results indicated that different planting densities of Turnera sp. had no significant effect on the attack intensity or population density of leaf roller caterpillars and stem borers. These findings indicate that increasing the density of Turnera sp. alone was insufficient to suppress pest infestations in E. pellita plantations under the conditions of this study.   Keywords: biological identification, Eucalyptus pellita, Refugia, Strepsicrates sp., Turnera sp.   ABSTRAK Serangan hama penggulung daun (Strepsicrates sp.) merupakan masalah serius pada Hutan Tanaman Industri (HTI) Eucalyptus pellita. Serangan penggulung daun mengurangi hasil fotosintesis yang memperlambat pertumbuhan. Pengendalian Strepsicrates sp. pada bibit Eucalyptus pellita menggunakan insektisida telah banyak dilakukan bahwa variasi jenis dan dosis insektisida tidak berpengaruh nyata terhadap mortalitas maupun morfologi.Penggunaan insektisida sintetik selama ini dinilai kurang efektif dan berisiko merusak lingkungan serta memicu resistensi hama. Pengendalian Terpadu dengan memanfaatkan agensia hayati dan tanaman refugia seperti Turnera sp. menjadi alternatif untuk menyediakan sumber pakan (nektar dan polen) bagi musuh alami.Penelitian ini bertujuan untuk menganalisis pengaruh berbagai tingkat kerapatan penanaman Turnera sp. dalam menekan populasi dan kerusakan akibat hama penggulung daun. Penelitian dilakukan di PT. WiraKarya Sakti menggunakan metode systematic sampling dengan plot pengamatan berukuran 8x8m². Perlakuan terdiri dari empat tingkat kerapatan tanaman refugia, yaitu: kontrol 0%, 25%, 50%, dan 75%. Parameter yang diamati meliputi intensitas serangan, persentase serangan, dan kepadatan populasi hama. Hipotesis penelitian menduga bahwa semakin tinggi kerapatan Turnera sp., maka populasi dan tingkat serangan hama akan semakin menurun secara signifikan.Hasil penelitian menunjukkan bahwa keberadaan Turnera sp. dengan berbagai tingkat kerapatan tidak berpengaruh signifikan terhadap intensitas serangan maupun populasi ulat penggulung daun dan penggerek batang. Dengan demikian, hipotesis yang menyatakan bahwa penanaman Turnera sp. efektif dalam menekan serangan hama tersebut pada tanaman E. pellita dinyatakan ditolak.   Kata kunci: Eucalyptus pellita, pengendalian hayati, Refugia, Strepsicrates sp., Turnera sp.
