      Abstract: Sumatra’s lowland tropical rainforest is in the third place after Kalimantan and Papua in terms of Indonesia’s plant species diversity. Shorea macroptera is one of the species from the Dipterocarpaceae family, known as an important commercial timber tree species. In September 2019, the study was conducted in Rantau Bertuah Forest, Siak Regency, Riau Province, Sumatra, with a total sample plot area of 1 ha. The data were analyzed to show the vegetation quantitative structure and composition on the study site using the Important Value Index, and the association of S. macroptera using the Ochiai index. The results recorded 55 plant species belong to 33 families on this study site. Dipterocarpaceae, Euphorbiaceae, and Fabaceae have the most abundant species, encompassed 51 species ≥10 cm in diameter with a total of 624 individuals. The result showed that the top three dominant species in this area, namely Callophyllum macrocarpum Hook.f. (IVI = 27.88%), Shorea parvifolia Dyer (IVI = 21.98%) and Gironniera nervosa Planch. (IVI = 19.99%). C. macrocarpum dominated all the regeneration levels: tree, sapling and seedling with IVI of 27.88%, 49.57% and 86.31%, respectively. S. macroptera has the strongest association with C. macrocarpum (Ochiai index of 0.73), followed by the S. parvifolia (Ochiai index of 0.61) and G. nervosa species (Ochiai index of 0.51). S. macroptera is widely used for industrial timber purposes and has limited distribution. Therefore, it is necessary to increase the efforts to manage it sustainably, especially in production forests.

  • The tree diversity of Srengseng Urban Forest in DKI Jakarta

    • Authors: Layla Azizah Ditha Sari, Denni Susanto, Mukhlison Mukhlison
      Pages: 13 - 20
      Abstract: Urban forests are part of urban green open spaces that are sought to be able to create a micro-climate and as a means of conservation for plants and the environment. The presence of urban forests is expected to be able to maintain urban ecosystems, so the presence of constituent trees becomes very important. This study aims to determine the tree species diversity of the Srengseng Urban Forest in DKI Jakarta. Data were collected using the systematic sampling method with nested sampling plots with 10% of sampling intensity. The results showed that the highest important value index at the seedling level was Adenanthera pavonina. Sapling and pole levels were dominated by Swietenia macrophylla. Meanwhile, the tree level was dominated by Gmelina arborea. The diversity index (H') of the urban forest at the seedling, sapling, pole, and tree were 1.32, 2.35, 2.24, and 2.81, respectively. Based on H’ value, the diversity index is in the low to moderate category. The research results will be useful for provincial governments as the basis for efforts to manage and develop the Srengseng Urban Forest.

           forest of Sangatta, East Kutai, East Kalimantan

    • Authors: Mariana Takandjandji, NM Heriyanto
      Pages: 21 - 31
      Abstract: Forest fires can reduce biomass, carbon storage, and vegetation diversity.  This research aims to obtain information on vegetation diversity, biomass, carbon content, and carbon dioxide equivalent in two lowland forests of Sangatta (East Kutai) that experienced forest fire in 2015 and 2017. The research was conducted in May 2019 by establishing one plot of 100m x 100m in 2015 and 2017 burned forests, respectively, and placed purposively in each site. The plots were divided into 25 sub-plots of 20m x 20m. All trees and saplings within its respected plots were identified and measured, including their DBH and height, while seedlings were identified and counted. The results showed that in 2015 burned forest contained 103 species and 38 families, including 59 species of trees (DBH ≥10cm) from 467 individuals. Meanwhile, in 2017 burned forest, we found 87 species and 36 families, including 69 species of trees from 398 individuals. We also found that three dominants species in 2015 burned forest were Macaranga gigantea with a density of 120 trees/ha or carbon sinks of 25.84 C kg, Melicope lunuankenda with a density of 63 trees/ha or 6.56 C kg, and Shorea seminis with a density/ha of 6 trees or 0.93 C kg. While three dominants species in 2017 burned forest were Alpitonia incana with a density of 165 trees/ha or carbon sinks of 6.87 C kg, Macaranga gigantea with a density of 60 trees/ha or carbon sinks of 6.18 C kg, and Callicarpa pentandra with a density/ha of 43 trees or 2.75 C kg. The estimated biomass, carbon content, and carbon dioxide equivalent in the burned forest in 2015 with a diameter ≥10cm were 102.20 tons/ha, 47.94 tons C/ha, and 175.94 tons CO2 eq/ha, respectively. Meanwhile, biomass, carbon content, and carbon dioxide equivalent in the burned forest in 2017 with a diameter of ≥10cm were 56.56 tons/ha, 26.58 tons C/ha, and 97.56 tons CO2 eq/ha, respectively.

      Pages: 33 - 43
      Abstract: Ectomycorrhizal fungi play an important role in a forest ecosystem. The genus of Amanita is one of the common ectomycorrhizal fungi in the forest. The information on the diversity of Amanita in Indonesia is not properly organized. This is due to most of the prior publications were not equipped with basidiomata descriptions. The current research aimed to inventory the diversity of Amanita and provide a description of the basidiomata from the Haurbentes Research Forest, West Java. Macrofungi exploration was carried out by the opportunistic sampling method and identification of fungi based on morphological characters. A total of seven species of Amanita were successfully described and identified in this study : Amanita sp.1, Amanita sp.2 sect. Vaginatae, Amanita sp.3 sect. Vaginatae, Amanita cf. alboflavescens, Amanita cf. virginea, Amanita cf. fulva and Amanita cf. sychnopyramis.This report is the first information of Amanita in research site and adds to the record of mushroom diversity in Indonesia.

  • Characteristic of plywood using wood mahagony bark powder as veneer
           bonding agent at several storage life

    • Authors: Nurfianah Mustamin, S Suhasman, Andi Detti Yunianti, Heru Arisandi, A Agussalim
      Pages: 45 - 52
      Abstract: Several barks from certain species, such as mahogany, have a relatively high tannin compound content. These tannin compounds have several hydroxyl groups that can be oxidized to produce radical groups. These radical groups can bind to wood chemical components through bonding mechanisms, such as esterification and phenoxy radicals coupling. The use of oxidized bark as a bonding agent has shown good characteristics of plywood. However, this method will have a problem, in terms of storage life, when being applied at industrial scale. The purpose of this study was to investigate the possible application of oxidized mahagony bark powder as a bonding agent for producing plywood and evaluate the relationship between storage life and the quality of bonding agent stock in the form of oxidized bark powder. The bark powder was oxidized using hydrogen peroxide and a catalyst. The oxidized powder was stored for 0 days, 1 day, 1 week (7 days), and 1 month (30 days) in a tightly closed container before being applied for the plywood manufacture. The tests carried out were physical and mechanical properties of plywood. The results showed that the physical properties of plywood using oxidized mahagony bark powder as a bonding agent with various storage periods have met SNI 5008.2:2016. However, the mechanical properties of the produced plywood were still below the standard. The results indicated that technology for producing plywood using oxidized bark powder is potential for further development

      Pages: 53 - 70
      Abstract: Mangrove forest is located along the coastal area and regularly waterlogged because it is influenced by the tides, and has an important ecological function for life. Mangrove forest, especially in urban areas, is the most threatened and damaged ecosystem. Surabaya has a mangrove forest in the Mangrove Botanic Garden of Gunung Anyar (MBGGA) with an area of 32,761 m2 and has the potential for educational tourism. Scientific information concerning plant species in MBGGA is needed to support this potential. This study aimed to inventory the mangrove plants and their associated species in MBGGA and their potential as medicinal plants. The inventory was carried out by tracking method while information on medicinal potential was obtained through literature study. The results showed that MBGGA had 14 mangrove species and 11 mangrove-associated species. Around 18 species are included in the least concern category and one in the vulnerable category of the IUCN red list. All plant species in MBGGA also have potential as medicinal plants and almost all their parts, including leaves, fruit, bark, and roots, can be used for that purpose. This study showed that MBGGA was rich in mangrove species and their associated plants which were potential as medicine.

  • No-till farming activites in some Umanapu (agroforestry land) on earthworm
           diversity : a case study in Detusoko District, Ende Regency

    • Authors: Nedy Saga, kristono Fowo
      Pages: 71 - 78
      Abstract: No-till farming (NTF) is an agricultural activity without tillage process, so it can minimize damage to soil structure, reduce erosion, and reduce the decrease in soil organic matter content related to the presence of earthworms. The purpose of this study was to determine the activity of no-till farming on earthworm diversity. Exploration of earthworms was carried out by hand sorting and monolith sampling methods in Umanapu (agroforestry) of Clove, Cocoa, Candlenut, Coffee and intensive tillage farms. The earthworms were identified by observing the morphology characteristics. In addition, the observation of biomass and population of earthworms, and environmental factors were also carried out. The results showed that there were four genera of endogeic and epigeic worms, namely Lumbricus, aMegascolex, Perithima and Pontoscolex. Diversity index (H'), maximum diversity (H'max) and species evenness (E) of earthworms in intensive tillage agriculture were low but in Umanapu of Clove, Cocoa, Candlenut and Coffee were moderate. The earthworm populations, earthworm biomass (g m2) and the ratio of biomass and population of earthworms (B/P) in Umanapu of Clove, Cocoa, Candlenut and Coffee were equal and significantly different from intensive tillage. The importance value index (IVI) in Umanapu of Clove, Cocoa, Candlenut, Coffee and intensive tillage agriculture were dominated by the Pontoscolex genus. In addition, the environmental conditions such as temperature and pH of soil at each location in Umanapu were not different, as well as the environmental temperature and humidity. NTF can maintain and sustain the existence of species, population and IVI of earthworms, so that soil biological properties are still maintained.
