AbstractNira derived from palm sugar (Arenga pinnataMerr.) can be made into several processed products such as brown sugar, vinegar, and wine. Nata de arenga is one of the products that utilizing from nira of palm sugar as one of the basic materials. This study aims to determine the Effect of starter fermentation time and the difference in the volume of starters for making nata from nira ofArenga pinnata.There are two stages used in this study; the first is making the starter, and the second is making nata. In the making of a starter, there are three starter fermentation’s time, namely starter which fermentation for four days (F1), six days (F2), and eight days (F3). In making nata, given the three different variations volume of starter, i.e., 100 ml (Va), 200 ml (Vb), and 300 ml (Vc) combined with starter fermentation’s time. Each treatment combination is three repetitions to enhance the validity of the results. The research data were then analysed using a completely randomized design (CRD) with a factorial experiment. The results showed the highest average yield in the combination of starter treatment which fermented for eight days with a 300 ml volume of starter (F3Vc). In this combination, the microbes in the fermentation medium are in optimum physiological conditions for the fermentation process.

Abstract
Biodiversity loss can be drastically aggravated by mining activities. Opened pit mining removes all material, including vegetation, above the ore deposit. Cement industries always implement opened mining as they process all rocks into cement. Restoration is known as the best human interference to drive the damaged ecosystem to recover. This study aimed to observe vegetation that was naturally grown under Pinus sp after 20 years of planting on ex-cement mining. The study was conducted in Sukabumi District, in three sites that were distributed in Cicantayan (2 sites) Sub District and Cibadak Sub District. Each location disses ivided into three points to conduct analysis vegetation in transects, for trees 2 units (10 x 10 m), shrubs 4 units (5 x 5 m), and grasses 5 units (1x1 m). The study resulted after 20 years of planting with Pinus (3 x 3 m) the sites recorded have been inhabited by 13 new species. They are 4 woody trees species, 4 species of shrubs, and 5 species of under-story (grasses). Tree stratum new inhabitants are Ficus spp, Macaranga gigantea, Schima wallichii, and Hibiscus tilliaceus, with the important value index (IVI) 57.83%; 53.67%; 33.17 %, 26.5%; respectively. Shrub’s stratum is inhabited by Mimosa invisa (IVI 76.66%); Eupatorium odoratum (IVI 76.66 %); Melastoma malabathricum (IVI 73.83%); and Clibadium suninamensis (IVI 72.837%). Whereas grasses stratum inhabited by Imperrata cyllindrica (IVI 98.77%); Brachiaria decumbens (IVI 98.60%); Themedia gigantea (IVI 43.11%); Setaria spp (IVI 31.83%), Cymbophogon citratus (IVI 27.69%). Shortly, restoration has encouraged natural colonization even acid mine drainage on the body waters remains occurred.

Abstract
Sweetpotato (Ipomea batatas), as a well-known plant and widely cultivated by farmers in South Sulawesi, if it is intercropped with satoimo taro (Colocasia esculenta (L.) Schott var. Antiquorum) as a staple crop should be suspected of being able to be a ‘safety’ crop when there is a failure in taro plant—due to the relatively new and un-well-known plant. The study was aimed to know the productivity and economic value of sweet potato planted as an intercropped on the staple crop satoimo taro plantation with several levels of compost. The study used a randomized complete block design with four levels of manure compost, namely 400 grams, 800 grams, and 1200 grams per staple plant, which put into and mixed evenly in the plant hole, and 1200 grams per staple plant which mixed evenly in the beds, and three blocks. Sweet potatoes were planted between staple plants satoimo that arranged 20 plants in a bed of 500 cm x 110 cm in two rows. The parameters observed were yields of tuber per plant, size of tuber, number of tubers, and dry weight of tops. The results showed that there is no level of compost affected significantly. However, both of the levels of 1200 grams of compost which is filled into the plant hole, and 1200 grams of compost mixed in the beds tended to be higher than the others in tuber productivity. By economic valuations, the RC-ratio and RC-ratio indicated that planting intercropped sweet potato are beneficially in all levels and increased after the levels of compost. Cultivating sweet potato intercropped in the two kinds application of 1200 grams levels in the taro plantation is more recommended.

Abstract
This study aimed to analyze the gap between visitors’ perception and expectation for better development of ecotourism potential in Bantimurung Bulusaraung National Park (BBNP). The gap analysis approach used a descriptive survey to 200 respondents selected by non-probability sampling in November 2018. Several ecotourism potentials assessed were accessibility, accommodation, cultural attractions, public facilities, human resources, information and natural attractions. The result showed that there is a higher expectation rather than perception of visitor in BBNP. The highest gap value was found in public facility [-1.71], while the lowest gap value was found in accessibility [-0.97]. Thus, public facility should be prioritized to develop in order to meet the visitor s’ expectation. In term of public facility, the highest gap value was found in communication facilities (telephone, fax, internet), while the lowest gap value was found in garbage dump and clean water availability. Therefore, the top priority to improve was the quality and quantity of communication facilities (telephone, fax, internet).

Abstract
Termites as wood biodeterioration agents have an important role in the ecosystem. This study aimed to observe termite diversity. A termites survey was conducted on Forest Concession Areas of PT. Inhutani I, South Sulawesi Indonesia. The termite specimens collected used the standardized transect sampling protocols at three different sites (forest with mixed vegetation, Pinus merkusii plantation, and logged-over area; and measurement of nine morphological characters of the soldier was conducted, i.e: head length without mandibles, head width at base of mandible, maximum width of head, left mandible length, pronotum length, maximum width of pronotum, postmentum length, postmentum width of postmentum, and the number of antenna segments. The results showed that there are four species found based on the morphological characteristics and morphometrical data, namely: Odontotermes javanicus., Nasutitermes sp., Schedorhinotermes sp. and Coptotermes curvignathus. The highest termite abundance was found in forest with mixed vegetation. The termite diversity in logged-over area and forest with mixed areas was moderate, while species diversity in pine plantation was low.

Abstract
This study aims to determine the effectiveness of a portable honey thickener machine on several qualities of Trigona incisa bee honey. The research was conducted in Tamalanrea, Makassar City, South Sulawesi, and the process of testing the quality of honey was carried out at the Makassar Health Laboratory Center and PT. SUCOFINDO Makassar. The data analysis used is quantitative by calculating each of the observed variables, then the data obtained from each variable is compared with the SNI Standard 01-3545:2013. The variables observed in this study were Hydroxymethylfurfural (HMF), water content, reducing sugars (glucose and fructose), Sucrose, Acidity (ml NaOH 1 N/kg), water insoluble solids, and ash content. The results showed that the portable honey thickener machine was very effective in improving the quality of Trigona incisa honey after being added to the portable honey thickener machine when compared to SNI 2018, but when compared with the SNI 01-3545-2013 standard, some of the honey quality variables did not meet the standards. Honey quality standards are water content, reducing sugars (Glucose and Fructose), acidity, insoluble solids in water, and ash content, while those that meet SNI Standard 01-3545-2013 are reducing sugars Glucose and Sucrose.

Abstract
Bacterioplankton community taxonomic composition of four large freshwater lakes of the Yeravninskaya depression (Bolshoye Yeravnoye, Gunda, Isinga, and Sosnovoye) which have great fishery significance for the region has been studied. The microbial community consists in the main of bacterial phyla Gammaproteobacteria (22-74%), Actinobacteria (4-35%), Firmicutes (1.17-34.6%), Bacteroidetes (0.3-7%), Cyanobacteria (0.9-6.5%) and Planctomycetes (1.5-10.5%). Total dissolved solids and sulphates accounted for 57% of the variation in the microbial community distribution. At the genus level, Acinetobacter dominated (average 21.4-25.2%). Pseudomonas, Exiguobacterium, and Massilia were also widespread. Their predominance may indicate a possible change in the structure of the community caused by natural and anthropogenic factors. In lakes Isinga and Gunda, a large number of bacteria of the genus Klebsiella was observed, Staphylococcus and Streptococcus were detected. These features indicate insufficient water quality as a result of anthropogenic impact.

Authors: Zaitseva S V , Dagurova O P 
Published: November 2021

Abstract
Three large freshwater lakes located in the Baikal region (Gusinoye, Shchuchye, and Kotokel) with high touristic significance were studied. Increased anthropogenic pressure is one of the most important causes of water quality deterioration (in particular, high solute and nutrient loads, high productivity). The structural features of microbial communities associated with an increased anthropogenic load have been revealed in different environmental gradients. It was shown that the genera Rhodobacter, Polynucleobacter, and Luteolibacter preferred environments with a higher trophic level and are indicators of possible anthropogenic impact.

Abstract
With the aim to find endophytic actinomycetes that synthesize bioactive compounds over 800 strains were isolated from 53 desert plants of the Gobi-Sumber, Umnugobi, Dundgobi, Dornogobi, Bayankhongor, and Gobi-Altai provinces of Mongolia. The HPLC study of strains with high anti-quorum sensing and antibacterial activities revealed that they produced flavonoids and phenolic compounds. Molecular diversity evaluated with 16S rRNA gene sequences of 123 strains showed that they belonged to 12 genera: Streptomyces, Promicromonospora, Micromonospora, Streptosporangium, Kribbella, Pseudonocardia, Nocardia, Micromonospora, Saccharothrix, Friedmanniella, Actinocatenispora, and Geodermatophilus, the latter two genera were registered in Mongolia for the first time. Moreover, the genus Actinocatenispora was isolated from plants for the first time.

Published: November 2021

Abstract
This study determined for the first time the changes in leukocyte composition of the pronephros (head kidney) of sand sculpin Leocottus kesslerii, (Sideleva, 2001) (Lake Gusinoye, Lake Baikal basin, Eastern Siberia, Russia), infected and uninfected with hemoflaggellates of the genus Trypanosoma. The results indicated that the trypanosomes modulated the development of the immune response of their host (suppression of B cell immunity and granulocytic reactions, activation of the leucopoiesis and monocytopoiesis). Selective suppression of immune response in host with trypanosomes promotes the survival and development of parasites.

Published: November 2021

AbstractGround beetles are sensitive to environmental changes. We analysed the consequences of haymaking and cattle grazing on communities of meadow ground beetles in Barguzin State Reserve. We assessed community structures during 12 years of the anthropogenic disturbance and after its cessation. The number of categories, types, and variants increased. A decrease in species diversity, a rearrangement of the composition of dominant species, an increase in the relative abundance and share of participation of dominants in the carabid community observed. Of nine dominant species of ground beetles six showed increase of the population number, while others were stable.

Published: November 2021

Abstract
In laboratory experiments, purposeful predatory inter-relations with moving insects have been revealed and described in three species of herbivorous voles: the East European vole, the narrow-headed vole, and the Tuva silver vole. The appearance of the full hunting stereotype in these species does not require preliminary experience, which indicates its innate nature. The hunting behaviour of the Tuva silver vole differed from that of the East European vole and narrow-headed vole, which probably reflects the phylogenetic relationships between these species.

Abstract
The article presents the results of applying the radiophysical method for modelling the dielectric permittivity on the example of Haplic Chernozem Molliglossic soils in the south of the Vitim plateau, depending on VHF and UHF wavelengths, temperature, and soil moisture. Depending on the heterogeneity of moisture reserves and heat content, the soil is considered as a three-layer medium with different soil characteristics. A difference in the frequency dispersion of the complex dielectric permittivity over the entire soil profile in the VHF and UHF ranges has been established.

Published: November 2021

Abstract
This study reveals temperature regimes of the three contrasting ecosystems in the permafrost area of Western Transbaikalia: meadow-forest ecosystem, forest-steppe and dry-steppe. Annual profile temperature data show the functioning of the studied soils in cryogenic and long-term-seasonally-freezing temperature regime. The most explanatory temperature variables are temperature penetration above 5°C at 100 cm depth and the amount of days with temperature above 0.5°C and 10°C at 20 cm, 50 cm, and 100 cm depths. Also, this work presents a comparative analysis of indicators of soil climate change and shows the spatial-temporal distribution of the reaction of the thawing and freezing depth in soils.
Natural and anthropogenic risks after a giant landslide in the Russian Far East

Published: November 2021

Abstract
At the Bureiskoe Reservoir (Far East, Russia) in December 2018 at a temperature of 36°C below zero the giant landslide is occurred. Landslide with a total volume of 24.5 million m3 blocked the reservoir from one shore to the opposite one, disrupting the access of water to a large hydroelectric power station downstream. Blasting operations were carried out with the use of trinitrotoluene and hexogen to revive the water flow. As a result of the landslide natural hazards (direct impact of the landslide, and tsunami) were happened, and the further strong impact was caused by humans (blasting). Volatile organic compounds (VOCs) and elemental composition were accepted as the main indicators of water quality. Parameters of these indicators varied at different near-shore sites above and below the landslide area. More significant changes are recorded after blasting operations. Hexane and toluene dominated the water passing the artificial channel. The genesis of VOCs can be associated with the biogeochemical processes of methanogenesis, methanotrophy, and the detonation products of explosives. Mercury, methanol, toluene, and xylenes in water samples were detected. This is evidence of the presence of a prerequisite for the formation of toxic methylmercury, a risk factor for aquatic biota.
The study of plants and embryozem soils on the technogenic dumps aimed to the improvement of the monitoring and remediation in industrial zones
Authors: Tupikova G S , Shergina O V , Egorova I N , Tupitsyna Yu S 
Published: November 2021

Abstract
In the soil cover of technogenic territories (Usolye-Sibirskoye, Irkutsk Region, Eastern Siberia, Russia) the initial, organo-accumulative, soddy, and humus-accumulative embryozems were identified. The period of soil formation was established: from 20 years (organo-accumulative) to 40 years (humus-accumulative embryozems). The relationship between regenerative successions of vegetation and stages of the soil-forming process was found. Each stage of post-technogenic soil formation (type of embryozem) corresponds to a certain type of plant communities possessing a clear discrepancy in the species composition. The first stage is represented by plant communities comprising few ruderal species on the initial embryozem. The more advanced stage is characterized by complex communities consisting of grasses, shrubs, and trees on the humus-accumulative soil. It has been shown that the humus content determines the degree of natural restoration of biocenotic functions in the post-technogenic ecosystem. Plants-concentrators that can be effectively used in phytoextraction of metals for decontamination of embryozems have been studied. Natural renewal of vegetation and the development of soil-forming processes serve as the best option for the rational use of nature management in comparison with the artificial restoration of natural landscapes in technogenic territories.
Assessment of regulating ecosystem functions/services of the urban forests in the Angara region (Eastern Siberia, Russia)
Authors: Shergina O V , Mikhailova T A , Mironova A S 
Published: November 2021

Abstract
The studies of urban forests were carried out on the territory of the Angara region in cities with a high air pollution index (up to 20) and with a high recreational load. The state of forest biogeocenoses was assessed by the parameters of trees, forest litter, and soil. Morphostructural, physicochemical, biochemical, and toxicological indicators were analysed. It was found that the selected biogeochemical parameters of trees and soils have a high level of correlation relationships under conditions of negative anthropogenic impact. The biogeochemical redistribution of technogenic pollutants in urban forests connects with the accumulating capacity of the soil cover and the regulatory function of trees, namely the ability to purify atmospheric air by accumulating toxicants in the needles and leaves. Regulatory function/service of pollutant absorption and air purification depends not only on the condition of urban forests, it is unequal for forests of different cities and, even more, for different forested territories.
