Abstract. Hartoyo APP, Prasetyo LB, Siregar IZ, Supriyanto, Theilade I, Siregar UJ. 2019. Carbon stock assessment using forest canopy density mapper in agroforestry land in Berau, East Kalimantan, Indonesia. Biodiversitas 20: 2661-2676. In the Reducing Emissions from Deforestation and forest Degradation (REDD+) program, remote sensing is the most important tool for measuring forest cover and carbon dynamic, including the utilization of software Forest Canopy Density (FCD) mapper. However, there have been rarely untested the accuracy of FCD applied in agroforestry landscapes to support carbon stock assessment compared to conventional field measurement data. This research was aimed to investigate the correlation between: (i) the value of FCD (%) and tree stand density (N/ha), (ii) the value of FCD (%) and basal area (m2/ha), (iii) the value of FCD (%) and total carbon stock (Mg C/ha), and iv) total carbon stock and percentage of canopy closure (%). Tree stand density, basal area, carbon stock and canopy profile were conventionally measured by trained members of local communities. The results of this study showed that the R2 between FCD and tree density was 37.7% (r = 61.4%), while the R2 between FCD and the basal area was 3.33% (r = 18.3%). The result of normality and heteroscedasticity tests showed that FCD was more accurate and precise in estimating the tree stand density model than the basal area model. Total carbon stock differed significantly (p<0.1) from tree density with R2 = 27.7% (r = 27.3%). Total carbon can be predicted using FCD with total carbon (Mg C/ha) = 13.005 + 0.826 FCD. Our findings suggest that FCD can be used as a new method to estimate tree density and total carbon stock cheaply, efficiently and accurately to support carbon stock assessment in agroforest practices. In carbon assessment, total carbon stock can also be estimated using canopy closure measurement.

Abstract. Siregar UJ, Rahmawati D, Damayanti A. 2019. Fingerprinting sengon (Falcatria moluccana) accessions resistant to boktor pest and gall rust disease using microsatellite markers. Biodiversitas 20: 2698-2706. Sengon (Falcataria moluccana Miq.) is a multipurpose fast-growing tree species and widely planted as community forest in Indonesia. According to Indonesian Light Wood Association (ILWA) F. moluccana wood products coming from forest industries in Jawa worth US$ 244.46 million export to China alone. The wood dust also has high potential as source for biomass-based energy in the form of wood-pellet. Monoculture plantation however often suffers from stem borer pest, known as boktor (Xystrocera festiva) and a gall rust disease, caused by fungi Uromycladium falcatarium. This research was aimed to characterize accessions of resistant and susceptible sengon individuals to both gall rust disease as well as stem borer pest using microsatellite markers. Totally 50 accessions of resistant and of resistant to stem borer pest were collected from Sumedang, West Jawa Province, while 88 accessions of resistant and of resistant to gall rust disease were sampled from Kediri, East Jawa Province and Sukabumi, Indonesia. Eight microsatellite markers could amplify most of the accessions used in this study and produce polymorphic fragments. High genetic diversity was detected in all of F. moluccana populations, with He ranged from 0.431 to 0.650. AMOVA showed that most genetic variations come from within populations. A dendrogram based on Nei’s genetic distance (1972) clustered some resistant accessions to either stem borer pest or gall rust disease separately from susceptible ones.

Abstract. Zakiyah U, Mulyanto, Suwanti LT, Koerniawan MD, Suyono EA, Budiman A, Siregar UJ. 2020. Diversity and distribution of microalgae in coastal areas of East Java, Indonesia. Biodiversitas 21: 1149-1159. Indonesia is well known as one of hotspot for biodiversity, including marine resources. However, Indonesia biodiversity has declined rapidly due to the changes in the aquatic environmental quality as the consequence of human activities. Biodiversity loss has been well studied in larger organisms, however, less is known for microorganisms, such as microalgae. Microalgae have received much attention recently due to its potential as renewable energy sources. This study aimed at describing biodiversity and distribution of microalgae in coastal areas of East Java and Madura, Indonesia. Six sites, i.e. Trenggalek and Sendangbiru representing south coast, Banyuwangi and Situbondo representing north coast of East Java, Pasongsongan and Pamekasan representing Madura north and south coast, respectively were sampled, which representing different background of anthropogenic development in these areas. Results showed that seawater condition in all sites is still good, with average pH 8.0 despite intense human activities, such as ecotourism, fishing and boat harbor, as well as residential area that has the potential to produce a lot of waste. Totally, there were 35 genera from all locations with varying abundance in each location and diversity index ranging from 1.105-3.312. Although most genera belonged to Bacyllariophyta, domination indices showed that there was not any single specific domination in all locations. Morisita indices showed that most distribution gave positive values indicating clumped dispersion of microalgae in all locations. Higher Shannon-Weaver indices characterized the south coast of East Java and Madura compared to the north coast of East Java area, which corresponded with lower dominancy indices.

Abstract. Riastiwi I, Witjaksono, Ratnadewi D, Siregar UJ. 2022. Genetic diversity of rosewood (Dalbergia latifolia) in Yogyakarta, Indonesia for plus trees selection. Biodiversitas 23: 2630-2639. Rosewood (Dalbergia latifolia Roxb.) or sonokeling is an important woody plant species with a high selling value. However, due to overexploitation, this species has been listed in Appendix II of CITES and its trade is strictly regulated. Therefore, the cultivation of this plant needs encouragement, and superior planting materials from selected plus trees are needed. This study aimed to examine the genetic diversity of the rosewood population and select plus trees in Yogyakarta Province, Indonesia. The plus tree selection was performed by comparing plus tree candidates with five other trees nearby in four districts, i.e. Bantul, Gunungkidul, Kulon Progo, and Sleman. As many as 61 plus tree candidates have been identified. Genetic diversity was assessed using 10 selected ISSR primers, resulting in 101 ISSR loci with average Polymorphic Loci values ??of 64.71% and Nei Heterozygosity of 0.23. The highest gene diversity (He=0.29) was found in the Kulon Progo population, and the lowest He=0.17 was in the Bantul population. The dendogram and PCA analysis put Gunungkidul and Bantul populations into one group, separated from the Sleman and Kulon Progo populations. Based on morphological and molecular analysis, six superior plus trees were obtained.

Abstract. Lukman, Dinarti D, Siregar UJ, Turjaman M, Sudarsono. 2022. Characterization and identification of agarwood-producing plants (Aquilaria spp.) from North Aceh, Indonesia, based on morphological and molecular markers. Biodiversitas 23: 4861-4871. Agarwood is one of the non-timber export commodities important as raw materials for bioindustry. There are 26 agarwood-producing plant species in Indonesia belonging to three families (Thymelaeaceae, Euphorbiaceae, and Fabaceae). This study aims to identify the agarwood-producing plant species in North Aceh District, Aceh Province, Indonesia, based on their morphological and molecular characters. The evaluated morphological characteristics include the bark and leaf structures of endemic plants. Molecular characterization was carried out by sequencing of matK, ITS, and trnL-trnF genes. The collected data were analyzed using the appropriate software, such as R software, BlastX, Geneious Prime and MEGA X. The evaluated 66 accessions were clustered into two major groups based on their morphology. Group 1 consisted of 10.61% of the evaluated accessions is identified as Aquilaria beccariana. Group 2 was further classified into two subclusters (Group 2a and 3b). Group 2a consisted of 10,61% of the accessions as A. malaccensis and Group 2b consisted of 78,79% of the accessions as A. microcarpa. All samples are identified as A. malaccensis based on the matK DNA sequences. Meanwhile, Groups 1 are identified as A. beccariana and Group 2a and 2b as A. microcarpa based on the ITS sequences. Based on the trnL-trnF sequences, Groups 1 and 2a was identified as A. malaccensis and Group 2b as A. microcarpa.

Abstract. Afililla Z, Suwanti LT, Mufasirin, Koerniawan HP, Suyono EA, Budiman A, Siregar UJ. 2022. The immunomodulatory effect of Glagah consortium microalgae polysaccharides based on splenocyte proliferation and cytokine production in vitro. Biodiversitas 23: 5205-5209. Indonesia is known as a maritime country that has various organisms, including microalgae. Some microalgae have many bioactivities, such as immunomodulatory activity. This study aimed to determine Glagah consortium microalgae polysaccharide (GCMP) and polysaccharide of Spirulina platensis (PSP) as an immunomodulator based on its effect on splenocyte proliferation and cytokine production in vitro. Crude polysaccharides were extracted by lye extraction method. Splenocytes were obtained from spleen of healthy mice and cultured in RPMI 1640 medium with and without Concanavalin A (Con A). Cells (3×105 per well) were treated with polysaccharide with dose gradually 0, 1.25, 2.5, 10 and 20 µg/mL. Splenocytes proliferation were observed by 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) assay. The supernatant was taken for the detection of cytokines using enzyme-linked immunoassay (ELISA). The results showed that GCMP, both with and without Con A at a concentration of less than 10 mg/mL decreased cell viability, on the other hand, a concentration of 10-20 mg/mL had a proliferative effect. Splenocytes were shown a proliferative effect at all concentrations of PSP, both with and without Con A. The concentration of polysaccharides, both GCMP and PSP, did not affect cytokine levels. In conclusion, based on the proliferation of splenocytes, GCMP has an immunomodulatory effect depending on its concentration.

Abstract. Herliyana EN, Oktavianto P, Siregar UJ. 2022. Identification and characterization of Pestalotiopsis spp. causing leaf spot and leaf blight on jabon (Neolamarckia spp.) in Indonesia. Biodiversitas 23: 6547-6556. Jabon (Neolamarckia spp.) is one of the fast-growing trees with high economic value for industrial plantations. Its monoculture planting system is faced with certain problems, such as the leaf spot and leaf blight diseases caused by Pestalotiopsis sp. Therefore, the aim of this research was to describe the morphology of Pestalotiopsis species through macroscopic and microscopic observations, followed by the identification of fungus using DNA barcoding causing leaf spot and leaf blight on the tree. A total of 11 Pestalotiopsis isolates were used for this research. The morphology was identified by observing mycelium colonies and fungal conidia, while DNA barcoding was initiated after DNA isolation using cetyltrimethylammonium bromide (CTAB) method, amplification with ITS 1 and 4 primers, followed by sequencing process. The results of DNA barcoding showed that 5 species of Pestalotiopsis, namely Pseudopestalotiopsis theae, Pestalotiopsis microspora, Pestalotiopsis palmarum, Neopestalotiopsis clavispora, and Pestalotiopsis virgatula were found associated with leaf spot and blight disease. All the five species were further classified into 3 clades using phylogeny according to their median cells and apical appendage shape. The clade X consisted of P. palmarum, N. clavispora, and P. virgatula with versicolorous median cells, whereas clade Y included P. microspora with concolorous median cell, and clade Z consisted Ps. theae with concolorous median cell and knobbed apical appendage.

Abstract. Lukman, Dinarti D, Siregar UJ, Turjaman M, Sudarsono. 2023. Isolation and molecular identification of agarwood-inducing fungi and their virulence test using Aquilaria sp. seedlings. Biodiversitas 24: 140-148. Agarwood is a lump of fragrant resin with a dark color and distinctive aroma from secondary metabolite products that accumulate in wood fibers produced from the genus Aquilaria and Gyrinops, a plant defense mechanism against damage caused by wounds and infection of specific fungal pathogens. The three main factors in producing agarwood sapwood are the presence of plants that have the potential to produce agarwood (family Thymelaceae) as a host, a supportive environment, and the presence of specific fungal pathogens. The isolation, identification, and virulence testing of local isolates must be made to get the correct agarwood-inducing pathogens without posing potential environmental problems. A total of five explants of Aquilaria sp. branches producing agarwood from the study site were used. This study aims to isolate local strains of fungi associated with agarwood formation from North Aceh regency, Aceh province, Indonesia, figure out their virulence against and ability to induce agarwood from seedlings of target trees, and determine their species identity. The experiments comprised isolation, macroscopic and microscopic identification, virulence tests, and species identification based on ITS sequences. The study resulted in five local Aceh isolates (LAI-1- LAI-5). Four isolates (LAI-1 - LAI-4) can induce agarwood formation, and oneisolate (LAI-5) is a white rot fungus. The ITS sequence analysis showed that LAI-1 - LAI-4 were Fusarium solani, while two colonies taken from LAI-5 isolate were identified as Ceriporia lacerataor Irpex laceratus (LAI-5 colony#1), and Daldinia eschscholtzii (LAI-5 colony #3). Based on these findings, the LA-5 isolate was probably a mixture of the two white rot fungus isolates.

Abstract. Istikorini Y, Cahyani NN, Haneda NF, Shabrina H, Nugroho A, Indriani F, Siregar UJ. 2022. Isolation and identification of fungi associated with Falcataria moluccana gall-rust in Kediri, East Java, Indonesia. Biodiversitas 23: 6171-6179. Gall-rust disease caused by Uromycladium falcatariae is the most important disease of sengon in Indonesia. Plant pathogenic parasitism as a biological control mechanism is usually associated with fungal biocontrol agents. This study aimed to isolate and identify the fungi associated with the sengon gall rust from the Forest Management Unit of Jatirejo, Indonesian State Forest Company, Kediri. Fungi were isolated from the black or gray-green patches of gall-rust samples on Potato Dextrose Agar (PDA) plates. The fungi were identified using macroscopic and microscopic examinations. The molecular identification of fungal DNA was amplified by PCR using a specific internal transcribed spacer primer (ITS1/ITS4). The PCR products were sequenced and compared with the other related sequences in GenBank (NCBI). DNA barcode identification results showed 9 isolates containing of 8 species, namely Fusarium oxysporum, F. solani, F. chlamydosporum, F. circinatum, F. incarnatum, F. verticillioides, Lasiodiplodia theobromae, and Pestalotiopsis palmarum. This result showed that the Fusarium was the most fungi commonly found fungi on the gall's rust teliospore surface.

Abstract

The embryogenesis (SE) has important role for genetic engineering of cassava (Manihot esculenta Crantz). However, the success of SE induction depend on plant growth regulator s (PGR)s and treatment enriched in induction media. This experiment tried to induce callus formation of cassava from several in vitro explants: immature leaf, apical bud, and internode; and to develop somatic embryogenesis of cassava in several media enriched with tyrosine and copper sulphate (CuSO4) added into media enrich with picloram as treatment. Different response of explants source to callus induction treatment from those three varieties in callus induction as well as friable callus formation were found in this experiment. The best medium to induce varied with variety; MS media supplemented 12 mg/L picloram + 0.5 mg/L CuSO4 was the best for “Adira 4” and half MS and half GD media supplemented 12 mg/L picloram + 100 mg/L tyrosine for “Malang 6”. All treatments resulted somatic embryo which developed indirectly and in morphologically normal somatic embryos
