Abstract. Budi SW, Wibowo C, Sukendro A, Bekti HS. 2020. Growth improvement of Falcataria moluccana inoculated with MycoSilvi grown in post-mining silica sand soil medium amended with soil ameliorants. Biodiversitas 21: 422-427. High aluminum content in soil of post-mining silica sand area inhibits plant growth. MycoSilvi is an inoculum of Arbuscular Mycorrhizal Fungi (FMA) enriched with Mycorrhizal Helper Bacteria (MHBs) which plays an important role for improving plant growth in unfertile soil medium. The aims of this research were to analyze the growth response of Falcataria moluccana (Miq.) Barneby & JW Grimes) seedlings treated with MycoSilvi and soil ameliorants (compost and lime) in post-mining silica sand soil medium. The randomized complete design with factorial scheme was used in this study. The results showed that the interactions of MycoSilvi and Soil ameliorant significantly increased height, diameter, biomass and mycorrhizal colonization of F. moluccana. Combination of MycoSilvi variant 3 and lime increased height, diameter, and biomass of F. moluccana by 965%, 147%, and 1427% respectively, as compared to those of control plants. The mycorrhizal roots colonization in those treatments was 98%. The addition of compost and lime increased pH and decreased Aluminum and Fe of the soil medium. F. moluccana seedlings have high mycorrhizal dependency on post-mining silica sand soil media. These results indicate prospective uses of MycoSilvi and soil ameliorants for improving plant growth in unfertile soil medium, including soil in post-mining area.

Short communication: The dissimilarity in plant species composition of savanna ecosystem along the elevation gradient on Flores Island, East Nusa Tenggara, Indonesia. Biodiversitas 21: 492-496. Savannas in Indonesia are located from west to the east across the archipelago. The objective of this research was to investigate the dissimilarity of floristic composition among savannas at different elevations in Flores. Sixteen sampling plots, each measuring 20 x 20 m were spread over the lowland, midland, and upland savannas. We analyzed the differences in plant community composition among the savannas using NMDS ordination and SIMPER analyses available in PRIMER V.6. As many as 41 species of plants were found in all of the sampling plots. The lowland savanna plant community consisted of Themeda arguens, Zoesya sp., Chromolaena odorata, Crotalaria sp., Adenanthera pavonina, Ocimum sp., Lantana camara in the groundcover layer, and Ziziphus jujube, and Borassus flabellifer at the tree layer. The midland savanna had almost similar composition, except the occurrence of Imperata cylindrica and Leucaena leucocephala, and the upland savanna plant species were Cyperus sp., Polygala paniculata, I. cylindrica, Melastoma malabathricum, C. odorata, Centella asiatica, Vaccinium sp., and Cymbopogon sp. The savannas in Flores were invaded by invasive exotic species, namely L. camara and C. Odorata which may pose serious threat to the existence of savannas.

Abstract. Priawandiputra W, Tsuji Y, Widayati KA, Suryobroto B. 2020. Dung beetle assemblages in lowland forests of Pangandaran Nature Reserve, West Java, Indonesia. Biodiversitas 21: 497-504. Dung beetles play crucial role in forest ecosystem, but no information on the dung beetle fauna has been reported in lowland forest of Java Island, Indonesia. Pangandaran Nature Reserve (PNR) area, which is recognized as lowland habitat of wildlife, can also support diversity of dung beetles. This study was conducted to examine the dung beetle diversity in lowland forests of PNR. The dung beetles were collected using pitfall traps baited with five species of mammal’s feces and hand collection of beetles found on dung along the road, between 2016 and 2018. During the study, 853 individuals of dung beetles from 17 species were collected. The dominant species were Onthophagus babirussa with 434 individuals (50.8%). The species were not dominant in the mountainous forests of West Java and in lowland forests of Southeast Sulawesi and East Kalimantan. The highest dung beetle abundances were found during the dry season (August): 335 individuals in 2017 and 286 in 2018. However, the diversity index value of dung beetles in this study was lower in the dry season than in the wet season (t-test of diversity index, P<0.05). The dung beetle assemblages in PNR were barely similar to most dung beetle studies of other regions.

Abstract. Pratiwi, Narendra BH, Mulyanto B. 2020. Soil properties improvement and use of adaptive plants for land rehabilitation of post tin mining closure in Bangka Island, Indonesia. Biodiversitas 21: 505-511. Indonesia is still facing several environmental problems due to improper mining activities, such as tin mining activities in Bangka island. The area of post tin mining closure in this island has left tailing area over unstructured overburden. This condition causes infertile land, which is indicated by low physical, chemical, and biological soil properties for supporting plant growth. Therefore, amelioration material is needed to increase soil fertility in rehabilitating this area. The purposes of the study are to improve soil properties and the use of adaptive plants for land rehabilitation of post tin mining closure. The observation was carried out on plots with ameliorant materials treatment, and no treatment as a control plot. Adaptive plants used are trembesi (Samanea saman), sengon buto (Enterolobium cyclocarpum), and ampupu (Eucalyptus urophylla); while ameliorant materials were mixture of overburden materials, NPK fertilizer, lime (dolomite), topsoil material, and compost, with proportion 49%, 1%, 10%, 20%, 20% of media weight respectively. The results showed that three years after planting, ameliorant treatment plots showed growth percentage of E. urophylla, E. cyclocarpum, and S. saman as 96.1%, 73.4%, and 52.4% respectively, while in the control plots were 94.1%, 93.8%, and 35.0% respectively. The ameliorant treatment plots as compared to control plots, showed a significantly different effect on the growth parameters, both height and diameter for S. saman and E. cyclocarpum, while for E. urophylla, although the ameliorant treatment showed better growth parameters, but the differences were not significant.

Abstract. Nuryanto A, Bhagawati D, Kusbiyanto. 2020. Evaluation of conservation and trade status of marine ornamental fish harvested from Pangandaran Coastal Waters, West Java, Indonesia. Biodiversitas 21: 512-520. Pangandaran coastal waters are among the main supply areas of marine ornamental fish in Indonesia. However, no scientific data are available on the conservation and trade status of marine ornamental fish harvested in this region. This study aimed to evaluate the diversity, conservation, and trade status of marine ornamental fish species harvested from Pangandaran coastal waters. Fish were collected during surveys conducted in March, April, July, and September 2019. Species were identified by referring to the available guidance books. The conservation status was analyzed according to the IUCN database, whereas the trade status was evaluated based on the CITES database. A total of 107 marine ornamental fish species from 32 families and eight orders was obtained. The two out of these 107 species had an unresolved conservation status, whereas 24 species were listed as Not Evaluated, 80 species were listed as Least Concern, and one species was listed as Vulnerable by IUCN. Two species had an unknown trade status, whereas 104 species were listed as Not Evaluated and one species was listed in Appendix II of CITES. Our data prove that Pangandaran coastal waters have a high potential for supplying marine ornamental fish, with most of the species listed as having a Not Evaluated or Least Concern status. Most of the species identified were also categorized as having a Not Evaluated trade status.

Published: January 2020

Solid-state light detection and ranging, capable of performing beam scanning without using any mechanical moving parts, requires a phase-modulator array. Polymers facilitate the fabrication of efficient phase modulators with low drive power, owing to their high thermo-optic (TO) effect and low thermal conductivity. We designed and fabricated a polymeric phase-modulator array and analyzed the temporal response of the TO phase modulator. The frequency response of the phase modulator was measured for a Mach–Zehnder interferometer (MZI), and the transfer function was modeled in terms of multiple poles and zeros. The frequency response of a fabricated beam-scanning device incorporating the TO phase modulator was also measured. The temporal response of the beam scanner was confirmed to coincide well with that of the MZI modulator. The device exhibited a fast rise time of 12 ms, accompanied by slight power variations appearing for a long period (over hundreds of seconds), which originated from the inherent viscoelastic effect of the polymer materials.

Published: January 2020

An experimental platform operating at the level of individual quanta and providing strong light-matter coupling is a key requirement for quantum information processing. In our work, we show that hollow-core photonic bandgap fibers filled with laser-cooled atoms might serve as such a platform, despite their typical complicated birefringence properties. To this end, we present a detailed theoretical and experimental study to identify a fiber with suitable properties to achieve operation at the single-photon level. In the fiber, we demonstrate the storage and on-demand retrieval as well as the creation of stationary light pulses, based on electromagnetically induced transparency, for weak coherent light pulses down to the single-photon level with an unconditional noise floor of 0.017(4) photons per pulse. These results clearly demonstrate the prospects of such a fiber-based platform for applications in quantum information networks.
Enriching absorption features for hyperspectral materials identification
Authors: Guo Baofeng
Published: January 2020

Many materials have certain unique ‘spectral fingerprints’ in electromagnetic spectrum, which enables identification of materials based on hyperspectral imaging technique. In this paper, besides using the location information of absorptions, we propose to extract a group of real-valued parameters based on a detected absorption valley. These absorption parameters are chosen to characterize the details of the spectral absorption quantitatively, and are measured without human intervention. Moreover, we design an orientation descriptor to explore the local characterization for the shape representation of a hyperspectral absorption. According to the idea of information fusion, the augmentation of the absorption parameters and the orientation descriptor may increase the discriminatory ability and lead to an improved hyperspectral material identification. Simulations of material identification accuracy were carried out on two hyperspectral data sets, including a 7 classes of materials from ASD sensor, and a 16 classes of vegetation data from the AVIRIS 92AV3C. Results conclude the effectiveness of the method, which increases the identification accuracy compared to two classical approaches.
Multi-parameter sensing based on surface plasma resonance with tungsten disulfide sheets coated
Authors: Liu Yin , Xia Qi , Zhou Ai , Wang Xianbin , Yuan Libo
Published: January 2020

A tungsten disulfide (WS2) coated surface plasmon resonance (SPR) sensor based on gradient pitch Mach-Zehnder interferometer (GP-MZI) for measuring ethanol vapor concentration is proposed and verified by experiments. Under continuous CO2 laser heating, a MZI based on GP helix structure is fabricated by twisting single mode fiber (SMF), which can excites multi-order cladding modes. A gold film is deposited on the surface of the GP helix structure by a magnetic sputtering coating machine. WS2 film is coated on the gold film of the GP helix structure, which increases the evanescent field strength of the twisted structure surface and enhances the interaction between SPR wave and ethanol molecules. Since the absorption of ethanol molecules by WS2 sheets will cause the change of effective refractive index (RI) of WS2 film, the intensity of transmission signal can be adjusted accordingly. For multi-order cladding modes, the effective RI and the effective thermo-optic coefficient vary with the modal order, so the RI and temperature sensitivity of different modal orders are also different. So, the ethanol vapor concentration, relative humidity (RH), and temperature can be simultaneously measured by monitoring the intensity of those dips with the resolution of ± 0.030 mg/L, ±0.035%RH, and ± 0.010 ℃, respectively. This sensor structure provides a promising platform for multi-parameter sensing applications.

Authors: Wei ShiLi , Zhu ZhengBo , Fan ZiChao , Ma DingLin
Published: January 2020

Computing a source-target map that yields integrable surface normal field is quite challenging for freeform illumination design. Here, we propose a least-squares ray mapping method to calculate a superior ray mapping by iteratively correcting an integrable map to approach the energy conservation and boundary condition. The process is implemented via solving three minimization problems. The first two problems can be figured out pointwise and the third can be converted to two decoupled Poisson equations with Robin boundary conditions. We demonstrate the robustness and high efficiency of the proposed method with several design examples.

Authors: Xu Jia , Jia Delin , Liu Yi , Tian Yuan , Yu Xiaomei
Published: January 2020

We report a tunable terahertz (THz) metamaterial absorber (MA) actuated by thermomechanical bimaterial microcantilevers. The THz MA, which is suspended on a silicon substrate by the bimaterial microcantilevers, is a sandwich structure with a bottom Al ground plane, middle air and SiNx dielectric layers, and a top Al rotationally symmetric open split ring resonator. Upon application of a current, a Ti heating resistor integrated on the SiNx dielectric layer induces the bimaterial microcantilevers to bend, causing the air layer thickness to change, modulating the absorption of the THz MA. The tunable THz MA exhibited a relative modulation depth of absorption of 28.1% at 0.69 THz and a thermomechanical sensitivity of 0.12°/K. This tunable THz MA has potential applications in filtering, modulation, control, and THz imaging.

Published: January 2020

Aim: This study aimed to identify the effect of the insulin-like growth factor 1 (IGF1) gene on growth, to uncover the genetic marker at the IGF1 gene, and to predict growth performance by analyzing growth models of Kejobong goats based on their genotype.

Materials and Methods: DNA and records of body weight (BW) and body measurements (BM) of Kejobong goats were collected, the IGF1 gene was amplified from the DNA template by polymerase chain reaction (PCR); the PCR products were then sequenced to determine single nucleotide polymorphisms (SNP). Linear mixed model (LMM) was used to analyze the association between SNP and growth traits. Four non-linear growth models were analyzed using non-LMM to describe the growth model and to compare the growth within genotypes.

Results: An SNP at intron 4 (g5752G→C) genotyped into GG and CC was significantly associated with BW and BM. Goats of genotype GG had a significantly higher BW and BM (p<0.05) than those of genotype CC. Growth analysis showed that the von Bertalanffy model was the most fit for describing BW, the Brody model for chest width and hip height, the Gompertz and Logistic models for heart girth, and the von Bertalanffy and Gompertz models for hip width.

Conclusion: An SNP at intron 4 of the IGF1 gene was associated with the growth trait and was usable as a genetic marker candidate for improvement of growth traits of Kejobong goats while von Bertalanffy model provides proper and accurate estimates of parameters to describe the growth performance of Kejobong goats.

Published: January 2020

Riedel`s thyroiditis is a rare disease with an unknown etiology, which is characterized by replacement of the thyroid gland tissue with a fibrous connective tissue, the main characteristic sign is the stony-hard texture of the gland, extending to the surrounding structures (trachea, esophagus, blood vessels and nerves). Dense adhesion causes clinical symptoms of tracheal compression, such as shortness of breath, hoarseness, coughing and dyspnoea. Regarding functional activity, both euthyroidism and thyrotoxicosis with the subsequent development of hypothyroidism can be observed. A difficult preoperative diagnosis allows only to suspect this disease, as well as differentiate it with some aggressive forms of cancer, and therefore the final diagnosis is possible only after histological and immunohistochemical examinations of postoperative material. The conservative treatment (mainly glucocorticoid drugs) and surgical intervention can be applied. It is necessary to be meticulous about the choice of a treatment method, taking into account the firmly adhesion with surrounding structures and a high risk of complications of surgical treatment of the thyroid gland. This case report describes a patient with a confirmed morphological diagnosis of Riedelapos;s thyroiditis after thyroidectomy. The peculiarity of this case is a clear positive correlation of the occurrence of subfebrile fever with the onset of the disease and its resolution after surgical treatment and a 11-month follow-up period.
Possibilities of preoperative ultrasound of neck vessels in the diagnosis of non-recurrent laryngeal nerve
Authors: Kuprin Aleksandr A. , Malyuga Viktor Y.
Published: January 2020

Background: According to the anatomical data, the non-recurrent laryngeal nerve is a rather common abnormality and can be found in 4.78% of people. At the same time, the non-recurrent laryngeal nerve is difficult to visualize during surgery, which increases the risk of its damage.
Aim: to determine the possibilities of ultrasound of neck vessels in the preoperative diagnosis of the aberrant right subclavian artery (arteria lusoria) and the abnormality of the branches of the vagus nerve.
Materials and methods: An observational, single-center, single-stage, randomized, uncontrolled clinical trial was performed, which included patients in whom surgery was performed due to thyroid and parathyroid pathology. In the preoperative period, all patients underwent the ultrasound of the right half of the neck vessels and the mediastinum with visualization of the brachiocephalic trunk and its branches. When the brachiocephalic trunk was detected in the preoperative period, mobilization of the thyroid gland during operation was started with ligation of the upper pole vessels, and followed by a search for the recurrent laryngeal nerve. However, if the brachiocephalic trunk was absent, the right common carotid artery was traced as low as possible to the aortic arch and assessed on its relationship with the right subclavian artery. In such cases, thyroid mobilization was started from the lateral surface of the lobe with the necessary visualization of all structures of this region and followed by a primary search for the inferior laryngeal nerve. When the non-recurrent laryngeal nerve was detected, the computed tomography of the brachiocephalic arteries was performed in the postoperative period.
Results: The study has shown that 202 (95.28%) patients out of the total 212 revealed the brachiocephalic trunk on preoperative ultrasound and the recurrent laryngeal nerve was located in a the typical place. Arteria lusoria was detected in 4 (1.89%) cases after the preoperative ultrasound. In this group of patients the non-recurrent laryngeal nerve was identified during operation and the aberrant right subclavian artery was confirmed at computed tomography. In 6 (2.83%) cases the brachiocephalic trunk could not be detected on ultrasound due to the constitutional features of the patient. However, in all these cases, the typical recurrent laryngeal nerve was identified during a surgery.
Conclusions: The ultrasound of the neck vessels is the effective method to detect arteria lusoria, which is the predictor of the non-recurrent laryngeal nerve.

Rights And Treatment Of Prisoners Of War Under Islamic International Humanitarian Law: A Legal Analysis
Authors: Abdullahi Ibrahim
Published: January 2020

The central thrust of this paper is on the legal analysis of the rights and treatment of prisoners of war under Islamic International Humanitarian law. Islamic Law as a complete system of law has corresponding rules regulating the treatment of prisoners of war and imbibed therein is the elementary considerations of humanity. This paper makes use of the doctrinal methodology in making legal analysis of the Rights and Treatment of Prisoners of War under Islamic International Humanitarian and in so doing, making cross references with the International Humanitarian Laws of the Geneva Conventions. The paper concludes that the fundamental rules and principles relating to the rights of prisoners of war under Islamic Law show striking similarities with that of the Geneva Conventions. However, issues of maltreatment of persons detained in armed conflicts as well as lack of political will by belligerents to respect and prevent violation of International Humanitarian Law (IHL) are increasingly common area of concern to the extent that Islamic laws and norms relating to the rights and treatment of prisoners of war is a better alternative to conventional  International Humanitarian Laws and can be used as a model for improving the contemporary International Legal Regime

Published: January 2020

The evolution of NIgerian State is shrouded in cultural complexities that are built on linquistc  variations and ethno-religious discontents. Asa a product of the British imperialism, the 1914 amaglmation of the northern and southern protectorates saw the emergence of what became an independent NigerianState on October 1, 1960. Thus, the activities of these imperialists led to the birth of Nigeria's naionalism which was couched in ethnic nationalism rather than true pan Nigerianism. This ethnocentrism has advertently deepened Nigeria's problems and led to the evolution of several regime system that manifested into resource control, independent movement and ethnic militants. Scholars and policy-makers alike, have over the last two decades tried several workable political system without actually arriving at any possible solution thereby stoking the flame of ethnic based crises that fraught Nigerian sovereignty. Against this background, the proclamation of the Sovereign State of Biafra was celebrated with attended war that followed therein. Therefore, it is understood that the aftermath of the war still linger and gave birth to Indigenous People of Biafra. While it could be said that the bulk of Nigerian resources are committed to finding solution to the existing political structures, it is obvious that the weighter problems arising from corruption, prebendalism and lack of true federalism that resulted to the evolution of ethnic millitias are still neglected. Therefore, the study identifies corruption, favouritism and nepotism as the majorproblems of ethnic politics in Nigeria while applying thematic, and historical analytical method as a method of analysis
