Published: November 2021

Abstract
The model of the skipjack tuna resource management that can provide maximum rent can be done with a clear ownership regime (sole owner) or in the condition of MEY balance. However, the management and utilization of skipjack tuna resources must also consider the factors that can result in overfishing of both biological and economics overfishing. This study aims to assess the management and utilization of skipjack tuna fisheries resources in North Gorontalo Regency using a bioeconomic approach. Data processing is done by approaching the bioeconomic model using skipjack tuna fisheries biological and economic parameters. The results showed that the maximum rent obtained in skipjack fisheries in North Gorontalo Regency was at the MEY regime compared to the MSY and OA regime. However, based on the actual data obtained, it is known that the average production of skipjack tuna in North Gorontalo Regency has not reached the optimum catch value in the equilibrium condition of MSY (hMSY
), but in some period the actual catch value has passed the optimal catch value (hMSY
), this means that skipjack tuna has overfished (biological overfishing). While the actual production value of skipjack tuna catches in North Gorontalo Regency has passed the production of optimum MEY (hMEY
). This condition indicates that actually skipjack tuna resources have experienced an economic overfishing.

Abstract
The blue shark (Prionace glauca Linnaeus, 1758) was a targeted shark caught in the artisanal fisheries in Tanjung Luar, West Nusa Tenggara. This species was caught by drifting longline. The study aims to obtain the parameter population, size distribution and sex ratio of the blue shark from these waters. The research was conducted in Tanjung Luar during 2019-2020, and a total of 1676 blue sharks were caught by drift longline. The data were analyzed by using ELEFAN II. The size blue sharks varied from 73 cm to 397 cm total length (TL), with mean length was 266 cm for males and 72-390 cm with mean length 255,61 cm TL for females. Male was dominated sex ratio. The equation growth for blue shark for male was Lt = 400 (1 – e−0.28 (t-0.2921)) and female was Lt = 390 (1 – e−0.25 (t-0.3307)) . The first captured (Lc ) length for males and females are 267.76 cm and 250.98 cm, respectively. Natural mortality (M) = 0.42/year, the fishing mortality (F ) = 0.50/year. The exploitation rate was > 0.55/year it means that utilization rate of blue sharks in Southern of Nusa Tenggara waters was susceptible to overfishing. This condition needs good management actions for this species.

Traditional wisdom as a starting point for conservation: A review
Authors: Supyan  , Susanto A N , Samadan G M , Sulistiono  
Published: November 2021

Abstract
Traditional wisdom was established on familiarity and concern for the homeland, where people are very dependent on their local resources and they developed management values based on their cultural beliefs. Traditional wisdom and its application can be useful for ecological management plans, especially conservation programs. The application of traditional wisdom as a starting point for conservation is based on: (1) Community institutional system (2) Community collective knowledge (3) Community relationship with their environment. Traditional wisdom is part of the basic theoretical framework in strengthening research designs with specific local knowledge, including environmental relationships that occur in the area. When conservationists recognize usefulness of traditional wisdom, they can engage in knowledge exchange and foster sharing of responsibilities with indigenous peoples. This type of exchange can also provide opportunities for indigenous peoples to develop scientific infrastructure.

Abstract
Coconut crab is a coastal animal that lives in costal forest on islands of tropical Indo-Pacific. Crab populations are currently under threat of extinction. Several issues contribute to this, including high levels of exploitation, degradation of their native habitat, land clearance, and plantations development. This study aimed to examine the biomorphometric of coconut crabs, which includes the composition, sex ratio, distribution, widht and weight relation, condition factors and gonad maturity level. The descriptive explorative methods was used in this research. The results showed that the composition of 156 coconut crabs consisted of 82 females. The results obtained a balanced sex ratio. The size of the carapace width obtained ranged from 40.15 to 88.55 mm, with a weight of 150-565 grams. The relationship between width and capacity is allometric. The values obtained from these factors ranged from 1.01 to 1.03 for men and 1.01 to 1.012 for females. The gonad maturity level of male and female mud crabs was dominated by TKG III and IV. This indicated that the research time was in spawning period.
Reafirmation of archipelagic state principle through the establishment of archipelagic region law in Indonesia
Authors: Abdulajid S , Tauda G A , Achmad M J 
Published: November 2021

Abstract
Archipelagic regions characterized by vast ocean area and groups of small islands are dominant factor in affirming the identity of the Republic of Indonesia as an archipelagic state. However, it has not been sufficiently accommodated in Indonesian national legislation. The principle of an archipelagic state should be adopted mutatis-mutandis to be formulated in the management of autonomous regions, not only in Law Number 23 of 2014 concerning Regional Government which is lex generalis in nature, but also in the specificity of the administration of regional governance in archipelagic regions which is lex specialis. The “Principle of Archipelagic State” needs to be implemented into “Principle of Archipelagic Region” for regions with archipelagic characteristics. In this context, an Archipelagic Regional Law is very much needed to reinforce the identity of the Republic of Indonesia as an archipelagic country, and to overcome extraordinary development disparities between eastern Indonesia dominated by islands regions and western Indonesia dominated by large islands.

Authors: Maskun  , Assidiq H , Bachril S N , Al-Mukarramah N 
Published: November 2021

AbstractIndonesia has ratified the United Convention Law of the Sea of 1982 with the Law No. 17 of 1985 concerning the Ratification of United Nations Convention on The Law of the Sea 1982. It means that Indonesia has the right to use, conserve, and manage fish resources in the Indonesia’s Exclusive Economic Zone (IEEZ). To guarantee the optimal and sustainable management of Indonesian fish resources, the role of fishery supervisors and community participation in an efficient and effective manner is needed. Law enforcement in the field of fisheries is very important and strategic to support fishery development in accordance with the principle of fishery management, so that the sustainable development of fisheries can be done continuously. Therefore, the existence of legal certainty is absolutely necessary to support fishery management in Indonesia.

Published: November 2021

Abstract
The inconsistency of the state’s commitment to the protection of the archipelago’s indigenous people in the management of coastal areas and small islands has become more apparent since the passage of Law Number 11 of 2020 concerning Job Creation. This research is normative legal research that analyzes the synchronization of legislation relating to the management of coastal resources and small islands that are responsive to the protection of indigenous people. The results show that (1) Recognition of indigenous people according to the Job Creation Law is placed on government legal politics in accordance with the provisions of the applicable legislation, showing the incompleteness of norms, which has implications for the weak position of indigenous people in managing coastal resources without recognition/determination as legal subjects. (2) Indigenous people who have received recognition/determination from the local government have the privilege of including the management area as part of the RZ WP3K and managing coastal resources and small islands in accordance with customary law, as long as it does not conflict with the applicable laws. As a result, the research’s recommendations are as follows: (1) Policy advocacy, encouraging acceleration of the legislative process for the Draft Law on Indigenous People and the Draft Law on Archipelagic Regions; and (2) Empowerment, support for capacity building of indigenous people to be critical and innovative in sustainable coastal and small island management through community development.

Authors: Mahabror D , Zulkarnain R , Waryanto  
Published: November 2021

Abstract
The minimal availability of fresh water during the dry season seems to be a classic problem that occurs in Pamekasan Regency. Based on data from the Regional Disaster Management Agency (BPBD) of the Pamekasan Regency Government, it shows that the drought that occurred in Pamekasan in 2019 was 325 hamlets in 82 well-known villages in 11 sub-districts. This data shows that most of the coastal areas in Pamekasan Regency are still experiencing a fresh water crisis. Therefore, alternative water treatment is needed to help provide fresh water in this area. Desalination is an important technology for coastal areas far from fresh water sources. The main objective of this study is to create a mini design for reverse osmosis desalination (RO) production in coastal areas to supply fresh water at the hamlet scale. The RO design for fresh water production of 5 m3/day is compact with brackish water well as raw material which has a TDS ranging from 5,000-10,000 ppm. In addition, this study also analyzes the economics of small-scale desalination based on the Revenue Cost Ratio (RC Ratio) with an RC Ratio value of 5.03, a Payback Period value of 0.17 years (2 months), and a production Break Event Point (BEP). Amounting to 149,007 liters (7843 gallons) and a BEP price of IDR 79.47/liter, the small-scale desalination business is declared profitable and feasible to be realized.

Published: November 2021

Abstract
An analysis of chemical element distribution in technozems of tailing dumps of the lead-zinc deposits of Eastern Transbaikalia is carried out. The potential toxicity of tailing mine technozems was calculated. A comparative analysis of the toxic element concentrations in the technozems of the lead-zinc deposit tailing dumps has revealed significant differences in the concentrations of toxic elements. It was found that the highest concentrations of toxic elements of the first class of hazard (As, Pb, Zn, and Cd) are characterized by the technozems of the Blagodatsky Deposit, while the lowest concentrations by those of the Khapcheranginsky Deposit. It has been established that the greatest ecological hazard is posed by the tailing dump of the Blagodatsky lead-zinc deposit, whereas a significantly smaller one by tailing dumps of the Khapcheranginsky and Novo-Shirokinsky deposits.

Published: November 2021

Abstract
The paper presents results of the analysis of the land use map compiled for transboundary Lake Khanka Basin using remote sensing data and geoinformation systems. The map reflects the distribution of 12 land categories in Lake Khanka basin in 2017 (arable land, abandoned arable land, paddy field, abandoned paddy field, shrubs and sparse growth, forest land, open pit, settlements, meadows and pastures, wet meadows and marshes, water bodies, forest cuttings and fire sites). The data of land use structure in the whole Lake’s watershed, in its Russian and Chinese parts are given. Data on the distribution of different land categories in the administrative territories of the rank of districts (Russia) and counties (China) are also presented. The analysis of land use structure showed that about 50 % of the Chinese part of the basin is covered by anthropogenically transformed natural complexes. The share of such lands in the territory of Russia amounts to 28 %. Agriculture is the most important factor in the change of natural complexes in Lake Khanka basin. Before early 1990s, the area of farmland had increased in the basin on both sides of the border, after that there was a significant reduction in cultivated lands, which had lasted for 10 years in the territory of China and for 20 years in Russia. Over the past decade, the area of cultivated areas in the basin and adjacent territories has extended again, which indicates an increase of anthropogenic impact and requires serious attention to monitoring of the ecological state of lands in the basin.

Abstract
In 2017, for the purposes of the Pulp and Saw Mill (PSM) “Polyarnaya”, the spillover dam was constructed on the Amazar River, a left tributary of the Amur River. Upon completion of the dam construction, the waters of the river formed a small river reservoir PSM “Polyarnaya”. This work covers findings on components and quantities of the newly formed reservoir at its initial stage and the data on biodiversity of its feeding flows. At this stage, the species composition of the flora and fauna in the reservoir falls in between the lacustrine and the riverine ones. The riverine conditions are observed in the upstream area of the reservoir; the middle area bears an intermediate status; while the limnetic zone near the dam features transformation of the river system into a lake-like running-water ecosystem. Seasonally, in the period from spring to autumn, phytoplankton showed a decreasing trend of the quantitative values; whereas the total abundance and biomass of zooplankton were increasing; zoobenthos featured lack of trends; macrophytes contents were different from season to season being abundant in the Amazar River near the urban settlement in spring and in the Amazar River downstream from the dam in autumn. Consequently, the initial stage of the formation of the reservoir is rather similar to original watercourses in the physical and chemical parameters and in the composition of flora and fauna as well.

Abstract
Compared to research on eutrophication in lakes, our understanding of eutrophication in rivers remains extremely limited. This is especially true of the impact of fires, which have become much more frequent in recent decades. Since the risks of eutrophication in rivers as a result of fires increase, it is important to timely assess the impact of fires on the state of rivers draining fire-prone territories. The aim of the study is to select and evaluate the reliability of criteria for impact of fires on eutrophication in stream on the example of the Simmi River (Bolon Nature Reserve, Far East, Russia). The tasks of the work are to assess the fire-prone of the territory from remote sensing data and and to identify markers of the impact of fires on the Simmi River. The fire-prone of the river watershed was estimated by the fire repeatability. The in situ study dealt with river bottom sediments. The sampling was carried out in in three month and the third year after the fire. To assess the impact of fires on eutrophication in the Simmi River, we used the P content in bottom sediments as a marker of the nutrient loading. The obtained results indicate high fire-prone and repeatability of fires the river watershed. In the first months after the fire, the response of the river system is the sequestration of P soluble compounds as a result of the binding of phosphate ions to vivianite. Vivianite is formed on the surface of clay microaggregates, which are removed by the stream over time. In three years after fire, vivianite-clay microaggregates were not detected. Flushing in flow system tends to reduce the scale of the fire impact.
Pollution and biodiversity: a case study of the Argun River Basin
Authors: Kuklin A P , Ts Tsybekmitova G 
Published: November 2021

Abstract
We analyzed the studies on the hydrochemical composition in the Argun basin and evaluated the level of pollution. We found that the water of the Argun River was contaminated by organic substances and toxic elements. We distinguished 9 major types of the ecosystems based on the prior findings. The prevalent species of Cladophora fracta was chosen as an indicator for the monitoring of the Argun drainage basin pollution by toxic elements. The concentrations of toxic elements in algae remained unchanged for a long term and they appeared to be more informative for the assessment of pollution than the rapidly changing water quality. It is necessary to determine indicator hydrobionts for each type of the ecosystems within such a vast territory as the Argun basin. Our findings showed that current mining production produces a negative ecological impact on the quality of the water ecosystems which should be considered during further developments. It is necessary to conduct a research on the regional background concentrations for toxic elements in water and hydrobionts, and to enlarge the list of indicator hydrobionts for water quality assessment.
Interaction of fresh and submarine saline groundwater in the coastal zone of the Sea of Okhotsk and the Sea of Japan
Authors: Kulakov V V 
Published: November 2021

Abstract
The multidirectional interaction of fresh groundwater of land with a mineralization of 0.1 - 0.2 g/dm3 and submarine saline groundwater in the coastal zone of the western coast of the Sea of Okhotsk and the Sea of Japan has been characterized. The main hydrochemical background in the coastal zone of the seas is created by ultra-fresh and fresh hydrocarbonate groundwater of land in the free gravity runoff zone. The main types of submarine groundwater are silt sediment waters, pore-stratal and fissure-stratal waters of sedimentary rocks, fissure and fissure-vein waters of effusive, metamorphic and intrusive rocks. With the salinity of the modern sea waters within the range of 30-34.4 g/dm3, a decrease is traced from 27-30 g/dm3 in the sediments of the Upper Miocene-Holocene aquifer complex to 14-20 g/dm3 in the sediments of the Oligocene-Lower Miocene complex. Fresh groundwater of volcanogenic hydrogeological basins, the deposits of which have been explored in basalts, are distinguished by special advantages. These waters do not have environmental restrictions for drinking, they belong to the highest class and their resources may well be involved for a worthy use within the region and beyond.
