Abstrak

 

Di daerah perkotaan pada umumnya menunjukkan adanya peningkatan pertumbuhan penduduk dan bangunan yang mengakibatkan berkurangnya daerah resapan air yang dapat menimbulkan banjir pada musim hujan dan juga kualitas udara yang kurang baik yang bisa ditimbulkan dari kebakaran hutan dari daerah disekitarnya. Hal ini juga terjadi di Kelurahan Bambu Kuning, untuk itu tim menawarkan untuk meningkatkan kepedulian pemuda dengan memberikan pengetahuan tentang pentingnya lingkungan hidup bagi kehidupan manusia dan dengan pengetahuan tersebut pemuda dapat mengimplementasikannya kedalam suatu tindakan atau gerakan. Tim Pengabdian Dosen bekerjasama dengan Balai Pengelolaan Daerah Aliran Sungai dan Hutan Lindung dalam pengadaan bibit. Bibit yang diberikan adalah bibit Sirsak, Matoa, Mahoni, Pulai, Gaharu dan Ketapang Kencana.  Dalam pelaksanaan bantuan bibit tidak saja didistribusikan ke Kelompok Pemuda RW 09 Kelurahan Bambu Kuning saja, tetapi ada permintaan bibit dari pihak lainnya.  Pihak lain tersebut adalah: warga di RW 013 Kelurahan Sidomulyo Timur Kecamatan Marpoyan Damai, SMK Pertanian, SMA N 6 , TK Zamrad, SMK N 8, Kelompok Mahasiswa Pencinta Alam Unilak dan  Organisasi Mahasiswa BEM Unilak. Temuan yang menarik di lapangan adalah adanya keinginan dari SMA N 8 Kelurahan Palas untuk membuat kerjasama bagi dosen untuk melakukan pengabdian di sekolahnya untuk siswa-siswa di sekolah tersebut yang perlu untuk ditindak lanjuti.

Published: July 2019

Isolation and identification of mycoplasmas from different species of domestic animals have recently become increasingly important. This prompted us to carry out research work to simplify the methods of sampling, cultivation, cloning, and storage of mycoplasmas living on the mucous membranes of dogs and cats. However, the unique properties of these bacteria, actually occupying an intermediate position between extracellular and intracellular parasites, often lead to confusion and misunderstanding. Indeed, even highly qualified veterinarians often have the wrong judgment that mycoplasmas are obligate intracellular bacteria similar Chlamydia or Rickettsia. Therefore, before presenting the main results of our studies, we gave a brief description of these unusual bacteria in this small review, with putting a focus on the properties which prevent to effective laboratory diagnostics.

Due to climatic changes across the globe, alignment of processes and products according to international environment standards is a rising concern for business stakeholders. Though this reform process to minimize environmental impact is occurring across different industries and countries but at a varying pace. Therefore, environmental management is still naïve and often compromised. If it is left unaddressed, it would lead to massive protests and social movements in future which will be messy to deal with, since climate change is occurring at an alarming pace. Moreover, the environmental consciousness is rising among masses, it is inevitable to deceive stakeholders for long time in this information era where controlling information is impossible. Corporate scandals and information/data leaks regarding greenwashing can lead to social protests and corporate defamation. Although in most of the countries environmental reporting is not a legal requirement however it is a societal requirement in different communities. Organizations use obfuscation eco-friendly claims, vague visual imagery, selective disclosure of corporate reports, and misleading communication modes to intentionally portray false environment-friendly claims of poor environmental performance to maintain positive social image by deceiving stakeholders. These symbolic strategic practices have stark difference with the real environmental impact. human resource managers and employees play significant role in developing and implementing such environment friendly organizational culture. Therefore, human resource function can facilitate by designing systems to build green organizational culture in organizations. In this research paper the pre-existing literature on green organizational culture in organizations is be reviewed, since in the last decade many researches were conducted on this issue. This review will give a holistic view of existing literature to the future researchers and will help them to identify research gap. Moreover, it will help practitioners and decision makers in knowing the advantages and disadvantages of green culture in organizations, so that they will understand whole impact of opting it.

The author examines theoretical aspects of designing a virtual tour: Its essential components, tour types, technologies to be used. Qualitative features which allow to expect their rapid growth and implementation in many spheres, in particular, in libraries, are revealed. Library virtual tours are specified and characterized based on the study of different types of libraries. For this purpose, the www-sites of 236 libraries were reviewed. Significant divergence in interpreting the term of “virtual tour” in the museum and library spheres is revealed. The most popular technologies of designing such tours are described. The key objects of the library virtual tours are discussed, i. e. library’s history and current situation, individual divisions, or the most valuable units (old manuscripts, rare collections, etc.).
The Study of Syntactic and Semantic Features of Verbs In Problem Statement Section of Master Theses
Authors: Ebrahimi Seyed Foad , Hosseinzadeh Mansoor
Published: July 2019

The present study was carried to investigate the realisation of verbs in problem statement of English Language Teaching (ELT) theses. To reach this objective, 40 ELT theses, were chosen from reliable databases (ProQuest). The corpus was read carefully to identify the grammatical verbs. Then, the identified verbs were classified based on tenses, aspects and voices. Tenses comprise three tenses of present, past and future. Aspects consist of simple, progressive and perfect. Voices can be either active or passive. To analyse the data for the semantic meanings of the identified verbs, Biber et al.’s (1999) classification was used. After scrutinising the problem statements of forty theses, the data, it was found that the verbs of different tenses, aspects, voices and semantic meanings were used. The findings were discussed to give a clear picture of how verbs are used in problem statements of theses written by native writers of English. The findings may help instructors to equip their students with the ability to use the verbs appropriately in writing the problem statement of their theses.

Quality management system is the ability of an organization to maintain the quality of goods or services that are served. The efforts made by the company are to improve the management system that is prime with ISO 9001: 2008 which is an international requirement for a company's management system. PT Softex Indonesia is the first producer of sanitary napkin made in Indonesia which has obtained ISO 9001: 2008 certificate and applied it in the implementation of production activities. One way to achieve success in maintaining the quality of a product is by improving work performance in order to produce quality products. Based on this, the researchers analyzed the effect of implementing ISO 9001: 2008 on improving employee performance. The data used in this study were obtained from a questionnaire (primary) and several observations and direct interviews with parties related to employee performance. The analysis technique used is simple regression using hypothesis testing, namely F test and t test. Based on the results of the study the magnitude of the influence of the application of ISO 9001: 2008 which directly affects the improvement of employee performance. From this study, R Square value was 0.504, which means that 50.4% of employee performance improvement variables can be explained by its independent variables, namely ISO 9001: 2008, while the remaining 49.3% is explained by other variables outside of this study
A Genetic System for Methanocaldococcus jannaschii: An Evolutionary Deeply Rooted Hyperthermophilic Methanarchaeon
Authors: Susanti Dwi , Frazier Mary C. , Mukhopadhyay Biswarup
Published: July 2019

Phylogenetically deeply rooted methanogens belonging to the genus of Methanocaldococcus living in deep-sea hydrothermal vents derive energy exclusively from hydrogenotrophic methanogenesis, one of the oldest respiratory metabolisms on Earth. These hyperthermophilic, autotrophic archaea synthesize their biomolecules from inorganic substrates and perform high temperature biocatalysis producing methane, a valuable fuel and potent greenhouse gas. The information processing and stress response systems of archaea are highly homologous to those of the eukaryotes. For this broad relevance, Methanocaldococcus jannaschii, the first hyperthermophilic chemolithotrophic organism that was isolated from a deep-sea hydrothermal vent, was also the first archaeon and third organism for which the whole genome sequence was determined. The research that followed uncovered numerous novel information in multiple fields, including those described above. M. jannaschii was found to carry ancient redox control systems, precursors of dissimilatory sulfate reduction enzymes, and a eukaryotic-like protein translocation system. It provided a platform for structural genomics and tools for incorporating unnatural amino acids into proteins. However, the assignments of in vivo relevance to these findings or interrogations of unknown aspects of M. jannaschii through genetic manipulations remained out of reach, as the organism was genetically intractable. This report presents tools and methods that remove this block. It is now possible to knockout or modify a gene in M. jannaschii and genetically fuse a gene with an affinity tag sequence, thereby allowing facile isolation of a protein with M. jannaschii-specific attributes. These tools have helped to genetically validate the role of a novel coenzyme F420-dependent sulfite reductase in conferring resistance to sulfite in M. jannaschii and to demonstrate that the organism possesses a deazaflavin-dependent system for neutralizing oxygen.
Assessing the Hybrid Effects of Neutral and Niche Processes on Gut Microbiome Influenced by HIV Infection
Authors: Yin Guanshu , Xia Yao
Published: July 2019

That both stochastic neutral and deterministic niche forces are in effect in shaping the community assembly and diversity maintenance is becoming an increasingly important consensus. However, assessing the effects of disease on the balance between the two forces in the human microbiome has not been explored to the best of our knowledge. In this article, we applied a hybrid model to address this issue by analyzing the potential effect of HIV infection on the human gut microbiome and adopted a further step of multimodality testing to improve the interpretation of their model. Our study revealed that although niche process is the dominant force in shaping human gut microbial communities, niche process- and neutral process-driven taxa could coexist in the same microbiome, confirming the notion of their joint responsibility. However, we failed to detect the effect of HIV infection in changing the balance. This suggests that the rule governing community assembly and diversity maintenance may be changed by the disturbance from HIV infection-caused dysbiosis. Although we admit that the general question of disease effect on community assembly and diversity maintenance may still be an open question, our study presents the first piece of evidence to reject the significant influence of diseases.

First, single-factor experiments were conducted to evaluate GPR performance. The factors that were evaluated were (i) root diameter; (ii) root moisture level; (iii) root depth; (iv) root spacing; (v) survey angle; and, (vi) soil moisture level. Second, two multi-factor field experiments were conducted to evaluate the performance of the GPR in complex orchard environments. The GPR generated a hyperbola in the radar profile upon root detection; the diameter of the root was successfully determined according to the width of the hyperbola when the roots were larger than 6 mm in diameter. The GPR also distinguished live from dead roots, a capability that is indispensable for studying the effects of soil-borne and other diseases on the citrus tree root system. The GPR can distinguish the roots only if their horizontal distance is greater than 10 cm and their vertical distance is greater than 5 cm if two or more roots are in proximity. GPR technology can be applied to determine the efficacy of advanced crop production strategies, especially under the pressures of disease and environmental stresses.

THz time-domain spectroscopy (TDS) is a promising tool for quality control purposes in industrial applications, but the high cost and the relatively large laser sources still make it difficult to use the full potential of the technology for a decent price. In this work, a THz TDS system, which uses a commercially available Fabry–Perot laser diode emitting at 1550 nm, is presented. By dispersion compensation, pulses with a duration of 544 fs were generated, resulting in THz radiation with a bandwidth of 1.4 THz and a peak dynamic range of 56 dB with state-of-the-art ErAs:In(Al)GaAs photoconducting antennas. These results are compared with those of a conventional and expensive fiber laser system with a 90 fs pulse duration.

Previous research shows that freeze–thaw cycles represent one of the most dangerous threats to reinforced concrete (RC) structures. However, there is almost no experimental data on the effects of freeze–thaw cycles on the seismic behavior of RC columns showing flexure-shear failure. In this study, three columns with the shear span-to-depth ratio of 2.5 were subjected to different numbers of freeze–thaw cycles (FTCs) and pseudo-static testing. The seismic performance indexes of the specimens were analyzed in terms of hysteretic behavior, skeleton curves, shear deformation, and energy dissipation. The test observations show that the failure patterns of the test columns altered from the flexure dominated to shear dominated, owing to the more severe deterioration in shear capacity induced by freeze–thaw attack than in flexure capacity. The test results also indicate that freeze–thaw cycles significantly decrease the ductility and energy dissipation of test columns, and they increase the contributions of shear deformation to the total deformation.

Bone tissue is a material with a complex structure and mechanical properties. Diseases or even normal repetitive loads may cause microfractures to appear in the bone structure, leading to a deterioration of its properties. A better understanding of this phenomenon will lead to better predictions of bone fracture or bone-implant performance. In this work, the model proposed by Frémond and Nedjar in 1996 (initially for concrete structures) is numerically analyzed and compared against a bone specific mechanical model proposed by García et al. in 2009. The objective is to evaluate both models implemented with a finite element method. This will allow us to determine if the modified Frémond–Nedjar model is adequate for this purpose. We show that, in one dimension, both models show similar results, reproducing the qualitative behaviour of bone subjected to typical engineering tests. In particular, the Frémond–Nedjar model with the introduced modifications shows good agreement with experimental data. Finally, some two-dimensional results are also provided for the Frémond–Nedjar model to show its behaviour in the simulation of a real tensile test.

The purpose of this work was to analyse and characterize the behavior of a 5 kW/5 kWh vanadium battery integrated in an experimental facility with all the auxiliary equipment and determine whether it would be possible to ascertain the most appropriate application for storage of electricity in photovoltaic (PV) grid applications. The battery has been in operation for 9–10 months. During this time the battery has achieve a full cycle efficiency of approximately 65%. A slight reduction in efficiency is the result of the constant auxiliary power consumption from pumps amounting to 8–9% of rated power, meanwhile the stack is quite efficient showing a cycle efficiency of 73%.The operation of the pumps has been adjusted to fix the current density applied together with the state of charge in order to reduce unnecessary consumption related to the energy required for pumping. According to the results obtained, the intended improvement in global efficiency for the system has not been achieved by this proposed strategy. However, the flow factor evolution selected at this stage needs further optimization in order to establish a trade-off between the concentration overpotential and a detrimental loss in energy due to pumping. Therefore, one should be able to improve system performance through a better configuration of flow factors in order to reach total system efficiencies of 70–75% required for achieving a commercially viable product.

Published: July 2019

The Internet of things (IoT) technology, which is currently considered the new growth engine of the fourth industrial revolution, affects our daily life and has been applied to various industrial fields. Studies on overcoming the limitations of scalability and stability in a centralized IoT operating environment by employing distributed blockchain technology have been actively conducted. However, the nature of IoT that ensures connectivity with multiple objects at any time and any place increases security threats. Further, it extends the influence of the cyber world into the physical domain, resulting in serious damage to human life and property. Therefore, we aim to study a method to increase the security of IoT devices and effectively extend them simultaneously. To this end, we analyze the authentication methods and limitations of traditional IoT devices and examine cases for improving IoT environments by using blockchain technology. Accordingly, we propose a framework that allows IoT devices to be securely connected and extended to other devices by automatically evaluating security using blockchain technology and the whitelist. The method proposed in this paper restricts the extension of devices vulnerable to security risks by imposing penalties and allows only devices with high security to be securely and quickly authenticated and extended without user intervention. In this study, we applied the proposed method to IoT network simulation environments and observed that the number of devices vulnerable to security was reduced by 48.5% compared with traditional IoT environments.
Adaptive Algorithm on Block-Compressive Sensing and Noisy Data Estimation

Published: July 2019

In this paper, an altered adaptive algorithm on block-compressive sensing (BCS) is developed by using saliency and error analysis. A phenomenon has been observed that the performance of BCS can be improved by means of rational block and uneven sampling ratio as well as adopting error analysis in the process of reconstruction. The weighted mean information entropy is adopted as the basis for partitioning of BCS which results in a flexible block group. Furthermore, the synthetic feature (SF) based on local saliency and variance is introduced to step-less adaptive sampling that works well in distinguishing and sampling between smooth blocks and detail blocks. The error analysis method is used to estimate the optimal number of iterations in sparse reconstruction. Based on the above points, an altered adaptive block-compressive sensing algorithm with flexible partitioning and error analysis is proposed in the article. On the one hand, it provides a feasible solution for the partitioning and sampling of an image, on the other hand, it also changes the iteration stop condition of reconstruction, and then improves the quality of the reconstructed image. The experimental results verify the effectiveness of the proposed algorithm and illustrate a good improvement in the indexes of the Peak Signal to Noise Ratio (PSNR), Structural Similarity (SSIM), Gradient Magnitude Similarity Deviation (GMSD), and Block Effect Index (BEI).

Published: July 2019

With many lives lost every year in crashes, highway traffic safety is a major concern. With 93% of crashes being contributed to by roadway users’ poor behaviors, one of the most effective ways to improve highway traffic safety is to improve the performance of organizations enforcing traffic laws to change those poor behaviors. This research introduces a framework that makes it possible to benchmark the efficiency performance within the highway patrol. Data envelopment analysis (DEA), a mathematical methodology based on the concepts of optimization and linear programming, was used to develop that framework to measure the efficiency performance of a highway patrol’s divisions. Such framework is used to measure and compare the efficiency performance of 17 divisions of the Wyoming Highway Patrol to allow internal benchmarking and thus to improve the overall organizational performance. The concepts discussed in this paper can be implemented by highway patrol agencies for internal and external efficiency benchmarking. Although DEA has been utilized for organizational performance evaluation in multiple sectors, literature review to date has not identified any study that has specifically utilized DEA in the context of highway traffic safety from the highway patrol’s perspective. As such, this study is original and timely.
The Regulatory Role of Rac1, a Small Molecular Weight GTPase, in the Development of Diabetic Retinopathy

Published: July 2019

Diabetic retinopathy, a microvascular complication of diabetes, remains the leading cause of vision loss in working age adults. Hyperglycemia is considered as the main instigator for its development, around which other molecular pathways orchestrate. Of these multiple pathways, oxidative stress induces many metabolic, functional and structural changes in the retinal cells, leading to the development of pathological features characteristic of this blinding disease. An increase in cytosolic reactive oxygen species (ROS), produced by cytosolic NADPH oxidase 2 (Nox2), is an early event in the pathogenesis of diabetic retinopathy, which leads to mitochondrial damage and retinal capillary cell apoptosis. Activation of Nox2 is mediated through an obligatory small molecular weight GTPase, Ras-related C3 botulinum toxin substrate 1 (Rac1), and subcellular localization of Rac1 and its activation are regulated by several regulators, rendering it a complex biological process. In diabetes, Rac1 is functionally activated in the retina and its vasculature, and, via Nox2-ROS, contributes to mitochondrial damage and the development of retinopathy. In addition, Rac1 is also transcriptionally activated, and epigenetic modifications play a major role in this transcriptional activation. This review focusses on the role of Rac1 and its regulation in the development and progression of diabetic retinopathy, and discusses some possible avenues for therapeutic interventions.
Metabolic Plasticity and Epithelial-Mesenchymal Transition
Authors: Thomson Timothy M. , Balcells Cristina , Cascante Marta
Published: July 2019

A major transcriptional and phenotypic reprogramming event during development is the establishment of the mesodermal layer from the ectoderm through epithelial-mesenchymal transition (EMT). EMT is employed in subsequent developmental events, and also in many physiological and pathological processes, such as the dissemination of cancer cells through metastasis, as a reversible transition between epithelial and mesenchymal states. The remarkable phenotypic remodeling accompanying these transitions is driven by characteristic transcription factors whose activities and/or activation depend upon signaling cues and co-factors, including intermediary metabolites. In this review, we summarize salient metabolic features that enable or instigate these transitions, as well as adaptations undergone by cells to meet the metabolic requirements of their new states, with an emphasis on the roles played by the metabolic regulation of epigenetic modifications, notably methylation and acetylation.
