Abstract
The material for research was a collected fish in the littoral and sublittoral zones of the Islands of Nedorazumeniya and Zavyalov coasts (Northern part of the sea of Okhotsk) in June 2018 and August 2019.The authors’ research identified 22 and 25 species of fish that live in the summer in the littoral and sublittoral zones of the sea coast of Zavyalov and Nedorazumeniya Islands, respectively. Of these the most numerous are the Blue rockfish Sebastes glaucus (24.5-49.0%), and White spotted greenling Hexagrammos stelleri (13.5-35.7%). Most species are demersal and benthic ichthyocoen. 41% of the species are characterized by the broad-boreal near-Asian type of range, 28% - mainly boreal, 13% - Arctic-boreal, 9% - high-boreal near-Asian and broad-boreal Pacific. For the development of recreational fishing, 15 species of fish can be promising, for which size and weight indicators are given.
Evaluation of efficiencies of biological propylene oxidation in the presence of metals
Authors: Avdeeva L V , Golovanova S A 
Published: March 2021

Abstract
The effect of metal ions (iron, nickel, zinc) in concentration range (1÷60)×10−5 M on biological propylene oxidation by bacteria Methylococcus capsulatus (M) was evaluated. The influence of metal varied from activation to inhibition. It was found that at low concentrations (up to (1÷10) ×10−5 M) iron ions stimulate the biological propylene oxidation, while nickel and zinc ions have no that effect. When the metal concentration increases to 60×10−5 M, it leads to inhibition of propylene oxidation by both nickel and zinc ions, but the inhibition by iron was not observed. The minimum inhibitory concentrations for the studied metals were determined.

Published: March 2021

Abstract
At present, a significant area of Siberian dark coniferous forests is characterized by a significant decrease in resistance due to recurrent forest fires, mass reproduction of insect pests and diseases, which leads to their natural degradation and death. However, the intensity of the growth processes of the coniferous stand under certain forest conditions persists in the long term. Therefore, the creation of regression models of the course of forest growth with the identification of forest conditions is very important both from the point of view of practice and environmental monitoring. The object of the study was the stands of Siberian fir (Abies sibirica Ledeb) and Siberian spruce (Picea obovate Ledeb) of bonitet classes III-IV, growing in the conditions of the West Siberian southern taiga plain forest region on the territory of the Yenisei forestry of the Krasnoyarsk Territory. The initial data for studying the processes of natural growth of fir and spruce plantations were the materials of the mass inventory of 11097 units. As a result of the work carried out for modal fir-spruce stands, concentrated in the territory of Central Siberia (Yenisei forestry of the Krasnoyarsk Territory), regression models of the growth course have been developed, which make it possible to predict the dynamics of taxation indicators and reproduce the succession picture of the development of stands.

Authors: Wulandari S , Villano R 
Published: March 2021

Abstract
Palm cattle integration as an integrated farming system is intrinsically complex. The model involves different processes and interactions between various actors in the value chain. The participation of women farmers in agriculture is considered the primary social capital in creating agricultural sustainability and improving productivity, but norms and socio-cultural aspects often dictate these roles. Investing in women in smallholder-based supply chains is expected to increase productivity, reduce costs, and improve broader goals. Approximately 49% of agricultural households comprise of women farmers. While both men and women contribute significantly to palm cattle integration, rural women’s roles in production activities and technology transfer are not fully documented. On the other side, women’s participation in agricultural activities is still faced with various constraints. Hence, this study’s aim is twofold: to analyze the driving factors and constraints that motivate women’s participation and formulate strategies to increase women’s participation in palm cattle integration. This study provides useful information to develop appropriate intervention policies and strategies to support, enhance, and increase women’s participation in palm cattle integration.

Published: March 2021

Abstract
Peatland degradation is caused by various factors, such as excessive drainage and frequent fires. The Government of Indonesia established the Peatland Restoration Agency in 2016 to accelerate peatland restoration and peat’s hydrological function. This study analyses agroforestry in priority areas for peat restoration. The results showed that farmers applied agroforestry cultivated land by combining jelutong (Dyera costulata) with many types of commercial plants at a spacing of 3 m × 6 m. Growth of Jelutong showed good performance with an average growth of 1.42 ± 0.49 cm yr−1 diameter and a height of 91.33 ± 36.77 cm yr−1. The crops cultivated with jelutong included luffa (Luffa acutangula), bitter gourd (Momordica charantia), leek (Allium ampeloprasum), and chilli (Capsicum annuum). The average income per planting period ranging from IDR 850,000 up to IDR 19,250,000 for a 1000 m2 planting area. The best income and cost ratio (R/C) is bitter gourd farming with a value of 7, eggplant, luffa, and waxy corn with a value of 3, while the smallest is leek with a value of 2. Some farmers can develop their agriculture in the form of planting areas or agricultural varieties. The formation of agricultural capital has now begun with monthly contribution obligations at regular monthly meetings.

Published: March 2021

Abstract

Sesbania grandiflora is a fast-growing multipurpose legume tree used for animal feed, besides that. S. grandiflora has a high crude protein content. Several studies have reported regeneration of plantlets from explants but a successful transfer of regenerated plantlets following micropropagation of S. grandiflora has not previously been reported. The objective of this study was to regenerate S. grandiflora by tissue culture. Explants were cultured on Murashige Skoog (MS), Woody Plant Medium (WPM), and Gamborg medium (B5). The best medium was supplemented with different concentrations of naphthalene acetic acid (0.0, 0.08, 0.10 mg/l NAA) and butyric amino purine (1 mg/l BAP) for induction of shoots. Several concentrations of NAA (0.2, 0.4, 0,6 mg/l) were used to induce roots, and plantlets were then transplanted to acclimatization media. The basal medium, MS performed better than WPM and B5. The best shoot induction was obtained on MS medium containing 1 mg/l BAP and 0.08 mg/l NAA. Shootlets were rooted in WPM medium supplemented with 0.2 mg/l naphthalene acetic acid transplanted to acclimatization medium. MS medium and cotyledon explants can be used in micropropagation of turi.

Abstract
Rice crop improvement program for direct-seeded has been directed at identifying the quality of seeds with rapid uniform germination and biomass accumulation during the initial phase of seedling establishment. Seed and embryo size are thought as two critical factors in the emergence of faster and vigorous seedlings. For the reason, this study was purposed to evaluate the relationship between the size and shape of rice seed with embryo size and its effects on germination. This study was designed using rice seeds from 55 genotypes, which were grouped in three sizes (medium, long, and extra-long) and two shapes (medium and slender). Germination was conducted with the top of paper method in a controlled germinator (24h lighting, 25 ± 2°C, 95%). We have found that the size and shape of seed significantly affected (α < 0.05) to embryo length, the time of radicles and plumules emergence, and seedling dry weight. Longer seeds tended to have longer embryos and emerged of radicles and plumules faster. Meanwhile, longer seeds with slender shape tend to have greater seedling dry weight. The results informed that the size and shape of rice seeds could be considered important characters for early seedling vigor traits in direct-seeded systems.

Published: March 2021

Abstract
In this paper, the temperature variation characteristics and control methods of power battery during rapid charging are studied. For the problem of large heat production in power battery fast-charging process, a refrigerant-based direct cooling battery thermal management system were built based on the AMEsim one-dimensional simulation platform. The change law of the battery temperature and the influence of different types of control thresholds on the cooling effect and the thermal management boundary of the cooling process in the constant current charging method of were studied. The results show that in the cooling process with the temperature as the threshold value, the cooling response is good under the condition of lower C-rate. With the increase of the C-rate, the temperature threshold cooling can not meet the cooling response requirements. Based on the consequence, the battery’s SOC(state of charge) was proposed as the control threshold signal for the advance cooling. The simulation results show that the SOC threshold cooling can control the highest temperature of the battery below 40°C, meeting the requirements of battery operation request. Through the full cooling of the maximum power, it is obtained that the thermal management boundary C-rate decreases linearly with the initial temperature change, and the final temperature in different initial temperatures increases linearly with the increase of the C-rate.
