A bamboo inventory for Banggai Kepulauan has never been done. Knowledge of the islands’ floristic diversity is poor. This study explored bamboo diversity in Banggai Kepulauan, Central Sulawesi, Indonesia. We conducted fieldwork from June – July 2019 on the islands of Peleng and Bakalan. Bamboo specimens were collected and deposited in Herbarium Bogoriense. We describe these specimens here. We found eight species: Bambusa tuldoides Munro, B. vulgaris Schrad. ex Wendl., Dendrocalamus asper (Schult.f.) Backer ex Heyne, Gigantochloa atter (Hassk.) Kurz, Neololeba atra (Lindl.) Widjaja, Schizostachyum brachycladum (Kurz ex Munro) Kurz, S. lima (Blanco) Merr., and Thyrsostachys siamensis Gamble. Here we record information on morphology, habitat and distribution alongside photographs and an identification key to the bamboo species of Banggai Kepulauan.

Abstract. Damayanto IPGP, Rustiami H, Miftahudin, Chikmawati T. 2020. A Synopsis of Bambusoideae (Poaceae) in Lombok, Indonesia. Biodiversitas 21: 4489-4500. There is little documentation of bamboo on Lombok. Non-native Indonesian bamboos have been reported occurring in Lombok. As such, suspicious bamboo specimens and information in those reports need to be examined and possibly re-determined. This study aimed to provide updated taxonomical information of bamboo species in Lombok and to investigate the accuracy of previous studies regarding the existence of several non-native Indonesian bamboo species on the island (i.e. they do not have original distribution in Indonesia). Data from fieldwork were combined with specimens in Herbarium Bogoriense to create a synopsis of bamboo in Lombok and to develop an identification key to the species. Eleven species of bamboos in Lombok were reported from this study, namely Bambusa glaucophylla, B. maculata, B. multiplex, B. spinosa, B. vulgaris, Dendrocalamus asper, Gigantochloa apus, G. atter, Schizostachyum brachycladum, S. lima, and Thyrsostachys siamensis. Several doubtful species (B. albustiata, B. ventricosa, Guadua angustifolia, S. jaculans, Pseudosasa japonica) were presented to clarify the existence of a non-native Indonesian bamboo in Lombok. Moreover, there is not enough evidence to state Dinochloa sp. occurred in Lombok. The results of this study can be used by stakeholders for bamboo identification and as the baseline taxonomic account for future studies and conservation of bamboo species in Lombok.

Bambu memiliki kandungan ekstraktif dengan persentase yang berbeda antar jenis bambu. Penelitian ini bertujuan untuk mengetahui pengaruh perlakuan ekstraksi pada jenis bambu yang berbeda terhadap sifat papan partikel. Dua jenis bambu digunakan yaitu Bambu Petung (Dendrocalamus asper) dan Bambu Wulung (Gigantochloa atroviolacea). Perlakuan ekstraksi digunakan pada partikel bambu sebelum proses pembuatan papan partikel yaitu tanpa ekstraksi, ekstraksi air dingin dan ekstraksi air panas. Papan partikel dibuat dalam ukuran 25 cm x 25 cm x 0,7 cm, target kerapatan 0,9 g/cm3, jumlah asam sitrat 30%, serta kondisi pengempaan suhu 180°C selama 10 menit. Hasil penelitian menunjukkan bahwa interaksi perlakuan ekstraksi dan jenis bambu hanya berpengaruh signifikan pada sifat penyerapan air dan keteguhan rekat internal, sedangkan jenis bambu berpengaruh signifikan pada nilai kadar air, modulus patah dan modulus elastisitas. Semua papan partikel yang dihasilkan memenuhi standar Japanese Industrial Standard (JIS) A 5908 tipe 13. Pada penelitian ini, papan partikel dari bambu wulung tanpa perlakuan ekstraksi mempunyai nilai yang memenuhi standar tipe 18 dan berpotensi sebagai bahan baku untuk produk furnitur eksterior. Perlakuan ekstraksi dapat meningkatkan secara signifikan nilai keteguhan rekat internal papan partikel bambu petung, walaupun secara umum dengan jumlah asam sitrat 30% perlakuan tersebut tidak diperlukan pada papan partikel bambu Properties of Particleboard made from Petung Bamboo (Dendrocalamus asper) and Wulung Bamboo (Gigantochloa atroviolacea) Particles with Extraction TreatmentAbstractBamboo has extractives, which the percentage of extractive was different based on bamboo species. This research aimed to investigate the effect of extraction treatment at different bamboo species on the particleboard properties. Two types of bamboo were used, i.e. Petung bamboo (Dendrocalamus asper) and Wulung bamboo (Gigantochloa atroviolacea). Three extraction treatments were conducted to the bamboo particles before the particleboard manufacture, i.e. unextracted, cold-water extraction, and hot-waterextraction. The particleboard was made in the size of 25 cm x 25 cm x 0.7 cm, target density of 0.9 g/cm³, citric acid content of 30%, and pressing temperature of 180°C for 10 min. The results showed that the interaction between extraction treatment and bamboo species significantly affected on the water absorption and internal bond strength, however bamboo species affected significantly on the moisture content, modulus of rupture, and modulus of elasticity. All of particleboards could met the requirement of the 13 type of Japanese Industrial Standard (JIS) A 5908. In this research, particleboards made from wulung bamboo particles without extraction treatment have properties that met the requirement of the 18 type and the products have potential to be as exterior materials for furniture. In general, an extraction treatment was not an important step on the manufacturing of bamboo particleboard using citric acid 30% as adhesive. However, the extraction treatment could increase significantly the internal bond strength of particleboard made from petung bamboo.

Bamboo, among other natural plants, has a special structure, with different characterization along the culms and between species. In this study, the thermal stabilities of four bamboo species, named Dendrocalamus pendulus (DP), Dendrocalamus asper (DA), Gigantochloa levis (GL), and Gigantochloa scortechinii (GS), were investigated by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) under a nitrogen atmosphere. Each species was divided into three different portions: bottom, middle, and top, and fibres were manually extracted from the specified sections of each species. The thermal analysis of extracted bamboo fibres indicated that the thermal degradation behaviour of each bamboo species varied from bottom to top and between species. However, these variations were lower in DA species compared to GS, GL, and DP, because of minor differences between lignocellulosic components of its three portions. The top and middle portions of the four species degraded at a higher temperature range (314 to 379 °C) than the bottom portions. The results of this study suggest that DA and GS species, according to their thermal stabilities, are most suitable for use as reinforcement in composite materials.

Majority of the bamboo production in Northern India is accounted from forests where productivity is very low. Efforts are therefore required for enhancing the productivity of bamboos by undertaking organized cultivation outside the forest areas. The present study was undertaken for screening eight different bamboo species viz. Bambusa balcooa, B. bambos, B. nutans, B. tulda, B. vulgaris, Dendrocalamus asper, D. hamiltonii, D. strictus in terms of growth behaviour, biomass production, carbon storage potential and soil health. After six years of plantation, maximum clump height (10.67 m) and clump girth (5.93 m) was observed for B. nutans whereas minimum clump height and girth was observed for D. asper. Highest culm diameter was observed in B. vulgaris (6.23 cm). Total above ground biomass and carbon stock were maximum for D. hamiltonii (144.5 t ha-1 and 64.63 t ha-1 respectively) whereas minimum above ground biomass (14.34 t ha-1) and carbon stock (6.39 t ha-1) were accumulated by D. asper. D. hamiltonii was found to mitigate highest 237.2 t ha-1 CO2. Oxygen released from different species ranged from 17.1-172.6 t ha–1 during the six year of study. Soil health was significantly improved under all the bamboo species as compared to control. Among all bamboo species, D. hamiltonii was better species for its effect on soil health.

Bamboo is an evergreen plant native to Asia and America that grows at every altitude, even in unideal climate conditions. Betung bamboo or its scientific name Dendrocalamus Asper is one of the bamboo species that are easily found in peninsular Malaysia. This study examined the characteristics of Betung bamboo and its potential to manufacture chipboard. Several tests were conducted, namely modulus of elastic (MOE), modulus of rupture (MOR), thickness swelling (TS), and water absorption (WA) to evaluate the potential of Betung bamboo as the primary material in the manufacture of chipboard mixed with polyethylene as additive are the parameters considered. This study found that the composition of 70% bamboo and 30% polyethylene was produced optimum chipboard which met BS EN standards (British and European Standard). It was also found that the MOE and MOR values of the resulting chipboard exceeded the medium density board standards. For WA and TS values, the chipboard achieved the standard requirements. Thus, this study concludes that chipboard made of Betung bamboo with the addition of polyethylene is suitable to be applied for internal and external doors, and internal paneling for any commercial or domestic building and furniture.

Inventory, identification key, mapping, and management recommendation of bamboo species in the ecology park, center for plant conservation, botanic gardens–LIPI, Bogor Regency, West Java. This study aimed to make an inventory of bamboo species to provide an identification key, a distribution map of those bamboos, as well as, a recommendation on bamboo management in the Ecology Park. The study was conducted in January-February 2019 using the exploration method, located in the Ecology Park, Center for Plant Conservation, Botanic Gardens, Campus of Cibinong Science Center–Botanic Gardens (CSC–BG), LIPI, Cibinong, Bogor, West Java. The bamboo herbarium specimens were made to determine the bamboo species found in the Ecology Park. The bamboo specimens were processed and deposited in the Herbarium Bogoriense (BO). The morphology characters of bamboo were described and to be used to determine the species and also to provide an identification key. The distribution map of bamboo in the Ecology Park created and it was overlapped with the existing map of the Ecology Park area. The bamboo management recommendation was made based on the data of bamboo inventory and mapping. The results showed that there are three species of bamboo from 40 clumps found in the Ecology Park, namely Bambusa vulgaris (bambu ampel), Gigantochloa apus (bambu tali), and G. pseudoarundinacea (bambu andong). These bamboos were alleged spontaneous collection and mostly distributed near the lake and along the road. An identification key to the species and a distribution map of bamboo species in the Ecology Park were presented. These bamboos play an important role in the Ecology Park to maintain water availability and to help to prevent a landslide. It is recommended that bamboo clumps in Ecology Park need to be tidied by making a fence and thinning of bamboo clumps needs to be done at least every 2 years. The management staff need to enrich the bamboo species in the Ecology Park, particularly ornamental and endemic bamboo of Indonesia, such as Schizostachyum brachycladum (bambu gading) and Dinochloa scandens (bambu cangkoreh), planted in accordance with the bioregion where the species come from.

Binderless particleboards (BP) were produced from three different species of Sulawesi bamboos. Parring bamboo (Gigantochloa ater) was extracted from Tanralili Maros while betung bamboo (Dendrocalamus asper) and tallang bamboo (Schizostacyum barcahycladum) were extracted from Batu Papan Makale Tana Toraja. The bark and nodes were removed, followed by cutting into chips; air drying, and finally converting into fine particles. The particles were oxidized using hydrogen peroxide 15% based on oven dry particle weight and 7.5% ferrous sulfat based on hydrogen peroxide weight. Hot pressing was applied for 12 min at 180ºC. Seven types of bamboo BP were produced based on the raw materials, i.e. the bamboo species namely; parring bamboo, betung bamboo, tallang bamboo, parring-betung bamboo with ratio 1 : 1,  parring-tallang bamboo with ratio 1 : 1, betung-tallang bamboo with ratio 1 : 1, and parring-betung-tallang bamboo with ratio 1 : 1 : 1. The results indicated that the characteristics of betung bamboo BP were better than the two other bamboos. The physical and mechanical properties however have not fulfilled JIS A 5908 2003 yet. Differences in BP characteristics were caused by the chemical contents of bamboo, especially lignin that is different from species to species.
