Abstract. Handayani T, Maarif MS, Riani E, Djazuli N. 2019. Mercury levels and tolerable weekly intakes (TWI) of tuna and tuna-like species from the Southern Indian Ocean (Indonesia): Public health perspective. Biodiversitas 20: 504-509. Tuna and tuna-like species are essential sources of protein for much of the world and provide employment in areas where fishing and processing are concentrated, as well as their value are confirmed as extremely valuable. However, their benefits may be overshadowed by the presence of mercury. The main objectives of the study were to analyze mercury content in tuna and tuna-like caught from Southern Indian Ocean related to its correlation with the weight of fish. The method used was linear regression and tolerable weekly intake (TWI) calculation. Mercury levels in yellowfin tuna (Thunnus albacares) and bigeye tuna (Thunnus obesus) indicated significant variations with the level that ranged from 0.049 to 0.654 mg/kg across individual fish weight, while for tuna-like ranged from 0.014 to 1.908 mg/kg. All mercury levels in tuna not exceeded 1.0 mg/kg, while for tuna-like 7.3% (30 kg up), 27.3% (51 kg up) and 34% (51 kg up) for oilfish (Lepidocybium flavobrunneum), marlin (Makaira indica) and swordfish (Xiphias gladius) were exceeded of 1.0 mg/kg respectively. TWI calculation indicates that people who are not in high-risk categories (most adult and adolescents) may consume about 1,000 g of tuna a week and less than for tuna-like.

Abstract. Mawarni L, Nisa TC, Napitupulu JA, Karyudi. 2019. Determination of leaf status of soybean varieties on shading. Biodiversitas 20: 615-620. The shading tolerant soybean varieties could be identified through the character growth such as leaf status. This study was aimed to obtain the shading tolerant of soybean variety based on their seed size and on the leaf status. Design of experiments was a split-plot design with three replications. The level of shading as the main plot with four levels of treatment was without shading, 30%, 50%, and 70% shading. Soybean varieties as the subplot had 4 genotypes namely Anjasmoro, Pangrango, Tanggamus, and Nanti wherein one variety comes with large seed; two come with medium seeds and the other one comes with small seed. The leaf status for determination was the greenness of leaves, the sum of chlorophyll a, chlorophyll b, total chlorophyll a and b, the forms of chloroplasts and leaf area. The soybean varieties with different seed sizes showed the differences only on the leaf area but not on leaf greenness or on the sum of chlorophyll. Nanti variety, having small seed, turns out to have the largest leaf area but is not shade tolerant. The large leaf area may be due to the forming of tetra foliate leaves on Nanti variety. The form of chloroplast of Anjasmoro variety in 70% shading is better than other varieties. Therefore, determining leaf status can identify shading tolerant of soybeans.

Abstract. Wahidi BR, Yanuhar U, Fadjar M, Andayani A. 2019. Pathognomonic features and ultrastructural of Koi Herpesvirus infected Oreochromis niloticus. Biodiversitas 20: 497-503. Koi Herpesvirus (KHV) has caused considerable losses in the cultivation of the Cyprinidae family worldwide. In addition to infecting Cyprinidae, KHV can also infect other freshwater fish. This study reports histopathology and ultrastructural analysis of KHV that infect Nile tilapia. Although there are no specific clinical symptoms, pathognomonic indicating Nile tilapia fish has been infected with KHV have been found, i.e. through the formation of intranuclear inclusion body and cell swelling which essentially experience chromatin margination. In addition, histopathology results indicate changes or damage to other tilapia tissue, i.e. necrosis, hypertrophy, edema, hemorrhage, inflammation, congestion, degeneration, and apoptosis. These results indicate that KHV has been distributed and replicated in tilapia organs. Based on the Transmission Electron Microscopy (TEM) analysis, KHV virions have been detected in the cytoplasm or outside the cells on a size of 150-170 nm.

Abstract. Yemata G, Desta B, Fetene M. 2019. In vitro antibacterial activity of traditionally used medicinal plants against Xanthomonas campestris pv. musacearum in Ethiopia. Biodiversitas 20: 555-561. In Ethiopia, traditional medicinal plants have long been used to treat human and livestock ailments. Nevertheless, studies about the use of these plant extracts to control crop diseases are scarce. Therefore, the aim of the present study was to evaluate the antibacterial activity of traditionally used medicinal plants against Xanthomonas campestris pv. musacearum (Xcm). The bioactive chemicals from leaf samples were drawn using methanol by maceration method. Total phenolic content of the extracts was determined by Folin Ciocalteau reagent. The antibacterial activity of leaf extracts was evaluated by disc diffusion method. The phytochemical analysis revealed the presence of alkaloids, flavonoids, phenolic compounds, terpenoids, tannins and saponins. Extracts with higher total phenolic content had greater antibacterial activity. The extract of each species showed antibacterial activity against Xcm on a dose dependent manner. Significant differences were recorded between species and test concentrations. The extract of Bersama abyssinica exhibited the strongest antibacterial activity at 200 mg/mL followed by Ricinus communis, Eucalyptus citriodora and Acokanthera schimperi. At lower test concentrations, extracts of E. citriodora and R. communis revealed higher antibacterial activity. Moreover, these species had lower bacteriostatic and bactericidal concentrations. The results showed the potential potency of E. citriodora and R. communis leaf extracts in controlling enset bacterial wilt. However, further studies on the identification of chemical compounds and in vivo evaluation of the extracts are recommended.

Abstract. Silalahi M, Nisyawati, Pandiangan D. 2019. Medicinal plants used by the Batak Toba Tribe in Peadundung Village, North Sumatra, Indonesia. Biodiversitas 20: 510-525. Research of the medicinal plants by the Toba Batak ethnic has limited, even though the globalization and modernization resulted to degradation of the local knowledge. The objectives of this study were (i) documentation of medicinal plants used in the traditional therapies by the Batak Toba tribe of Peadundung Village, North Sumatra, Indonesia, and (ii) analysing the data by quantitative ethnobotanical tools such as use value (UV), cultural significance index (CSI), relative frequency of citation (RCF) and informant consensus factor (ICF) to determine the cultural importance of medicinal plants in order to develop a tool for their conservation. Semi-structured interviews with 41 identified respondents was the methodology employed for qualitative data collection. A total of 149 medicinal species of plants, belonging to 131 genera and 55 families, were recorded in the study which are used in the treatment of 21 categories of ailments. Plants with the highest UV were Eurycoma longifolia (UV=3.44), Curcuma longa (UV=2.67) and Zingiber officinale (UV=2.60). Eight species, namely Curcuma longa, Eurycoma longifolia, Allium cepa, Psidium guajava, Aleurites moluccanus, Piper betle, Citrus hystrix and Uncaria gambir were found to be having the highest RCF value of 1.00. Eurycoma longifolia (CSI=126), Curcuma longa (CSI=112) and Zingiber officinale (CSI = 105) emerged as the culturally most significant medicinal plants. Thrush and aphrodisiac use categories received the highest ICF of 1.00 each because the informants agreed of using only a single species for each of these categories. Eurycoma longifolia was used as an aphrodisiac whereas Averrhoa carambola was used against thrush. All these important and significant plants suffer the greatest harvesting pressure, hence their conservation should be given priority.

Abstract. Susila E, Susilowati A, Yunus A. 2019. The morphological diversity of Chrysanthemum resulted from gamma ray irradiation. Biodiversitas 20: 463-467. Chrysanthemum is a popular ornamental plant. The high market demand makes breeders develop new cultivars to meet market preferences. One way to get superior varieties of Chrysanthemum is by using gamma ray mutation induction which will increase the morphological variations. The purpose of this study is to determine the Chrysanthemum’s morphological diversity resulted from gamma irradiation through morphological markers. This experimental research used a completely randomized design (CRD) with one factor, i.e. radiation doses: 0 Gy (control), 10 Gy, 15 Gy, and 20 Gy. The observations were carried out qualitatively and quantitatively. The data obtained were analyzed using the SPSS 15.0 and the NTSYS (Numerical Taxonomy and Multivariate Analysis System) 2.02 program. The results showed that increasing the dose of gamma irradiation inhibited plant growth. Irradiation at 10 Gy and 20 Gy produced the most color changes in flowers compared to other doses. The basic color of 0 Gy irradiation is purple. Irradiation at 10 Gy and 20 Gy produced dark purple and deep red. Quantitative data showed that the treatment of gamma ray irradiation significantly affected the leaf length, leaf width, stem diameter, stem length, and diameter of flowers. The irradiation also caused changes in shape and texture of the leaves. The dendrogram showed that 20 Gy irradiation resulted the most diverse morphology compared to the control, 10 Gy and 15 Gy.

Abstract. Patantis G, Dewi AS, Fawzya YN, Nursid M. 2019. Identification of Beche-de-mers from Indonesia by molecular approach. Biodiversitas 20: 537-543. Sea cucumbers have been commercially traded around the world due to their nutritional values and health benefits. Sea cucumbers are marketed as processed sea cucumber, also known as beche de mer, teripang, haisen or gamat. Due to the high global demand of beche-de-mers, there have been several cases of fraud due to the visual shape and color similarities of processed sea cucumbers. Additionally, the local name diversity of Indonesian sea cucumbers making the identification of beche-de-mers difficult. Therefore, this study aimed to identify commercial sea cucumbers from selected locations in Indonesia by molecular approach. The targeted Cytochrome c oxidase subunit I (COI) was used in this research. A total of 25 beche-de-mers was purchased from local markets in Indonesia, i.e. Boalemo (17 local names), Pesawaran (5), Surabaya (2) and West Lombok (1). Results showed that 22 species of beche-de-mer were successfully identified, ie. Acaudina sp., Actinopyga echinites, A. lecanora, A. miliaris, Bohadschia argus, B. marmorata, B. ocellata, B. vitiensis, Holothuria sp. H. atra, H. coluber, H. edulis, H. excellens, H. fuscocinerea, H. fuscogilva, H. fuscopunctata, H. scabra, Pearsonothuria graeffei, Phyrella sp., Stichopus herrmanni, S. horrens and S. monotuberculatus. The identification of Indonesian beche-de-mers using molecular method could support the identification of the local sea cucumbers to overcome mislabeled and fraud. Correct identification is important for the record of beche-de-mer trade in Indonesia and further conservation management.

Antioxidant activity, total phenolic and flavonoid content of several indigenous species of ferns in East Kalimantan, Indonesia. Biodiversitas 20: 576-580. This study aimed to determine the total phenolic and flavonoids content and antioxidant activity of ethanol extract of several indigenous species of ferns in East Kalimantan. Total phenolic content was determined by Folin-Ciocalteau method and flavonoid content was measured by colorimetric method. Antioxidant activity was evaluated by DPPH (2,2-diphenyl-1-picrylhydrazyl) method. The result of photochemical screening indicated that the leaves of Plagiogyria pycnophylla, Plagiogyria glauca, and Stenochlaena palustris contained alkaloid, flavonoid, tannin, saponin, and steroid while Acrostichum aureum contained flavonoid, tannin, saponin and steroid. The result showed extract Acrostichum aureum had the highest total phenolic content (366.4573 ± 2.2117 mg GAE.g-1), flavonoid content (228.6087 ± 2.2548 mg QE.g-1), and very strong antioxidant activity with IC50 value 29.5303 ppm. There is positive correlation between total phenolic content, flavonoid with antioxidant activity.

Abstract

Ruchin AB, Antropov AV, Khapugin AA. 2019. Distribution, abundance, and habitats of rare species Parnopes grandior (Pallas 1771) (Hymenoptera, Chrysididae) in Mordovia and adjacent regions, Russia. Biodiversitas 20: 303-310. The study of biological and ecological characteristics is essential in conservation efforts of threatened and locally rare species. Obtaining the comparable data in different regions of a species range allows developing a conservation strategy. We aimed to study the distribution, acquired characteristics of the abundance and habitats of the biology of a rare species Parnopes grandior (Pallas, 1771) in the Republic of Mordovia (European Russia). As a result of our study, the biology of Parnopes grandior found in the Republic of Mordovia and in five adjacent regions (Volga River Basin, Russia) is described. In the Republic of Mordovia in 2008-2018, 18 habitats of this species were identified. In all cases, it was found next to the host wasp colonies of Bembix rostrata (Linnaeus, 1758). The species population was low (no more than five individuals per study site). In all the sites surveyed, it inhabited xerophytic plant communities on sandy disturbed substrate. In these habitats, the coverage of plants is low and does not exceed 20%. The list of plants visited by the adults of Parnopes grandior is given. In the adjacent regions, the species abundance is also not high, but the number of records and abundance increases significantly to the south of the Ulyanovsk region.
