Authors: Qu Shi , Zheng Yi , Yan Hua , Deng Weiqiang , Liu Taiyang 
Published: May 2021

Abstract
Operational effectiveness evaluation is of great significance for early warning operation of antimissile, which provides quantitative basis for equipment development, operational planning, combat method research and operational management. In view of the shortcomings of TOPSIS, this paper improves the TOPSIS method. First, before calculating positive and negative ideal solutions, it establishes corresponding standardized methods for different evaluation indexes to solve the problems of inconsistent impact of each evaluation index on operational effectiveness and the “drowning” of small value indexes by large value indexes. Second, it calculates the weight of each index based on combination weighting method to overcome the shortcomings of single subjective or objective weighted method. On this basis, the operational effectiveness evaluation method of antimissile early warning based on combination weighted TOPSIS is proposed, and the quantitative evaluation and comparative analysis of different operational schemes are carried out. The simulation results show that the effectiveness evaluation result of antimissile early warning operation based on combination weighted TOPSIS method is scientific.

Abstract
It is one of the main hidden dangers of power transmission lines accidents if there is the uncovered earth under or near power transmission lines. It can give the important early warning message to prevent the accidents through recognizing the uncovered earth region from aerial images of Unmanned Aerial Vehicle (UAV) power transmission lines inspection. Due to the low recognizing precision of Mask RCNN CNN (Mask Convolution Neural Network), this paper proposed an approach to recognize the uncovered earth region from aerial images of UAV by image feature fusion. The HOG and LBP features of aerial images were extracted and their dimension were reduced. Then these two features were fused by different weights. The experiments show that, (1) the average precision of recognizing the uncovered earth region can be above 80%, which is the lowest requirement to use; (2) the weights of two features should make the orders of magnitude of the two features as equal as possible. The approach is application for the first image filtering by the UAV airborne platform because it not only has enough good recognizing precision but also is very rapid, which provides a novel way for objective recognition from UAV aerial images.

Published: May 2021

Abstract
Text detection in complex scenes is very hard realize by the diversification of text distribution, direction, and typesetting. This paper proposes one scene text detection method with end-to-end structure with parallel backbone network and region segmentation. With multiple deformable convolutions and extracting features of multi-dimensional text regions, multiple candidate regions of different sizes are generated and corresponding states are further given. Experiments show that compared with baseline, this method can further adapt to the problem that the different shapes and angles of the target in the image lead to the decrease of accuracy.

Abstract
The current control principles of long-distance crude oil pipeline production and operation are all obtained by theory in the design stage, and lack of on-site actual operation verification. Based on the pigging data of the pipeline put into production in 2017, the simulation software SPS was used to establish the model. Based on the operating data of the pipeline in recent years, the control principles in the preliminary design are checked one by one to verify the reliability of the control principles and propose corresponding improvement suggestions for existing defects. The research results show that the initial control principle of the pipeline has two actual operation defects. One is the low setting value of the water hammer pressure relief valve in the BS station, and the second is the advance protection program error under the failure condition of the MD station; The simulation obtains the set value of the pressure relief limit of each station entry and exit under the principle of advanced protection, and the set value can be adjusted appropriately according to the pressure of the entry and exit pipelines of each station; the response time of each step of the control principle under different fault conditions is simulated, Provide optimization suggestions for some control principles. The above research results can minimize the failure results produced by the failure conditions under the premise of ensuring the effective control principle.

Published: May 2021

Abstract
We apply bayesian algorithms to studying the effects of binary stellar population models on the age determination of 46 new star clusters in Gaia DR2. The ages of star clusters are obtained via color-magnitude diagram (CMDs). The data are selected from two works. Our analysis focus on exploring the potential of bayesian algorithm to estimate the effects of binary stars on the parameter determination of star clusters. Our work is based on simple stellar population models of binary stars and single stars. As a result, the bayesian analysis shows that binary stars have significant effects on the determination of ages of star clusters. The models with binary stars report older ages for most star clusters. The age difference between binary-star models and single-star models follows a Gaussian distribution with mean of 1.2 Gyr.

Published: May 2021

Abstract
The consistency of the semen extender used is one of the deciding factors in the quality of the frozen semen. Water clover extract (WCE) was supposed to retain the semen content during freeze storage with the antioxidant compounds. The objective of this analysis was to determine the impact on the consistency of post-thawed Boer Goat Semen of the water clover extract supplement. The Boer semen was collected from 3 Boer bucks aged at 3 to 3.5 years Boer bucks which weighed at 40 to 42 kg. The semen was obtained by artificial vagina two days a week and the semen used for this research should have at least 80 percent individual motility and feasibility and maximum anomalies of 10 %. The semen was added with WCE at different concentration levels (0, 2, 4 and 6%) by using Tris-fructose citric glycerol diluents as the base extender. The study was done in a randomized way and the results were evaluated using a variance analysis followed by a multiple range test from Duncan. The results showed that a WCE supplementation with Tris-fructose citric glycerol diluent as the base extensor had a significant (P<.05) effect on motility, viability and integrity of plasma membrane but not on abnormalities (P>0.05). The research shows that the best way to preserve frozen boer goat semen consistency was to add 4% WCE in tris fructose citric glycerol.

AbstractAssociation is a relationship in an ecosystem between living organisms. Positive associations arise when a plant species is associated with other plant species, and negative associations occur under opposite situations. This study aimed to identify the relationship among dominant tree species of the National Park Mount Halimun Salak by producing a permanent 100 m × 100 m plot divided into 25 sub-plots of 20 m × 20 m to store the trees. Smaller sizes of 5 m × 5 m and 1 m × 1 m were nested on each sub-plot to inventory saplings and seedlings. Vegetation research determined the dominant tree species. In addition to an association coefficient, the Association indexes were determined by a contingency table of 2 × 2. The results showed that the composition of vegetation at the tree levels includes 32 families, 46 genera and 61 species; 28 families, 35 genera and 53 species at sapling stage; 24 families with 19 genera and 43 species at the seedling level.

Published: May 2021

AbstractDamping-off disease caused by a fungusSclerotium rolfsiiis one of important diseases on kenaf, a fiber-producing crop. The disease could cause considerable yield losses on fiber production. The use of resistant varieties is the most effective control method for the disease. Understanding the characteristic of resistance of kenaf accessions is important to support the development of resistant varieties. Therefore, this research aimed to determine resistant characters of 15 kenaf accessions to damping-off disease caused byS. rolfsii. The research revealed that there was one accession (CI/77/17/37) showed moderately resistance to S.rolfsii. In addition, five accessions (CI/77/17/21, CI/77/17/25, CI/190/31, C2/210/50/1, and C3/222/2/57) were susceptible and the other accessions were very susceptible toS. rolfsii. It was expected that this information would be useful for kenaf breeders to develop resistant varieties of kenaf to damping-off disease.

Published: May 2021

Abstract
Wehea-Kelay landscape is an unprotected area, located on the eastern part of Borneo Island. It is managed by 7 unit managements, which were mostly timber companies. We compiled and collated our avifauna data with previous studies. We recorded 273 bird species belonging to 60 families during field work. 61 species were protected based on Indonesian regulations. Among of them were threatened species with small population such as Great argus Argusianus argus, Storm’s stork Ciconia stormi, and Helmeted hornbill Buceros vigil. Although Wehea-Kelay is dominated by timber concessions, the landscape can still provide habitat for many species of bird. Nevertheless, anthropogenic pressures i.e. illegal hunting have increased and become a threat for birds particularly commercially traded species such as Leafbirds Chloropsis spp, White-rumped Shama Copsychus malabaricus, Common hill myna Gracula religiosa, and also Helmeted hornbill Buceros vigil.

Abstract
Growth and yield of copea can be affected by abiotic stress such as salinity. Aim of this study was to analyze the tollerant level of cowpea againts salinity. The study was conducted in the screenhouse of Iletri at Malang, East Java during the dry season of 2017. This study conduct using factorial completely randomized design with two replications. The first factor was two environments (non salt stress and salt stress with soil electrical conductivity 9.5 dS m -1). The second factor was 125 cowpea genotypes. Data measurement included plant height, number of branches, number of nodes, pod number, pod length, number of seeds per pods, and seed weight. The soil used in the trial was highly saline, and the stress intensity were ranged from 0.25 to 0.88 for all the observed characters. The genotypes responded variedly to salt stress, and there were a very significant effect on all the characters except the number of nodes. Seed yield and pod number per plant experienced the highest stress level with stress intensity above 0.80. Based on seed yield and the tolerance index, six genotypes were tolerant to the high salinity. The six genotypes were MLG 17019, MLG 17055, MLG 17060, MLG 17186, KT 4, and KT 6. Selected genotypes were prospective for development in the improvement of cowpea varieties tolerance to salinity.

Abstract
The study of bird community structure was carried out in the water sources area in “Malang Raya”. Birds have an important role in sustaining habitat conditions and ecosystem stability. The purpose of this study is to evaluate the condition and charachters of habitats and ecosystems of water sources, based on the bird’s community structure. In this present study, visual observation was used by the cruising method, then counting the number of species and number of individuals within a radius of 200 meters from the water source as a focal point of observation. Those methods were performed with three times replications a day during March 2019. Data collection was done at eight water sources, including Kendedes, Waras, Taman, Sira, Jenon, Wendit, Brantas, and Cangar. The analyses showed that the diversity index (H’) gain 2.88 scores, 0.92 scores for evenness (E), and 5.25 for species richness (R). Based on the results, We interpret that the ecosystem condition at eight sites of the water source can still support as a bird habitat under the carrying capacity. Overall, habitat and ecosystem conditions in the Malang Raya water sources still tend to be stable, with low ecological pressure.

Published: May 2021

AbstractRed and yellow inflorescence ofCelosiaindicated the content of betalain pigment, betacyanin and betaxantin. In vitro system through callus culture is one of the strategies for producing plant bioactive compounds including betalain. Therefore, this study aims to analyse the content and profile of betalain pigments inCelosiacallus in vitro induced by a combination of auxin and cytokinin. Callus was induced from in vitro cotyledonary and hypocotyl sprouts at 1 week after germination. Callus induction medium was MS + BAP + 2,4-D or NAA. Subsequently, the profile and content of betalain pigments in each type of pigmented callus and in vitro hypocotyl and leaves were analysed by HPLC method. Repeated subcultures every two weeks resulted three types of pigmented callus: red, yellow and greenish white. HPLC analysis of in vitro hypocotyl, leaf and callus tissue derived from red and yellowCelosiainflorescence detected six types of compounds, namely 1) amaranthin, 2) isoamaranthin, 3) betalamic acid, 4) miraxanthin V, 5) 3-methoxytyramine betaxanthine and 6) (S)-tryptophan betaxanthine. Callus from redCelosiacontains a small amount of betaxanthin which was higher in yellowCelosia. BAP:2,4-D combination produced higher total content of betalain pigments.

Published: May 2021

Abstract
Botanic garden play a central role in the ex-situ plants conservation. It is important to maintain the survival life of the living plant collections. Knowledge on the details of reproductive biology of the living collections becomes vital to monitor the success or failure of conservation efforts. Tabebuia pallida (Lindl.) Miers. (Bignoniaceae) is one of the living plants collection in Purwodadi Botanic Garden that need to be monitored. So far information on the reproductive biology of this species is still limited. Based on that, in relation to the conservation effort, the objectives of this study were to provide knowledge about the reproductive biology of T. pallida. The research was conducted at Purwodadi BG, from September 2019 to February 2020. Several important aspects of reproductive biology, including flower biology, pollen viability and stigma receptivity, breeding system (Out-Crossing Index), and pollination biology were investigated. The results showed that T. pallida was monocious, has a pinkish tubular corolla with a yellow throat. There was no spatial separation between the anther and stigma. At the time of anthesis, both pollen and stigma have been receptive. Based on flower biology, pollen ornamentation (reticulate type), and the Out-Crossing Index (OCI=3), the flower showed some characters of entomophily, but self-pollination was possible. There are some insects visitor, but that acts as a pollinating agent was Vespula. The availability of effective pollinators in botanic garden was an obvious requirement for successful plants conservation.
