PURPOSE

The essence of guideline recommendations often is intertwined in large texts. This impedes clinical implementation and evaluation and delays timely modular revisions needed to deal with an ever-growing amount of knowledge and application of personalized medicine. The aim of this project was to model guideline recommendations as data-driven clinical decision trees (CDTs) that are clinically interpretable and suitable for implementation in decision support systems.

METHODS

All recommendations of the Dutch national breast cancer guideline for nonmetastatic breast cancer were translated into CDTs. CDTs were constructed by nodes, branches, and leaves that represent data items (patient and tumor characteristics [eg, T stage]), data item values (eg, T2 or less), and recommendations (eg, chemotherapy), respectively. For all data items, source of origin was identified (eg, pathology), and where applicable, data item values were defined on the basis of existing classification and coding systems (eg, TNM, Breast Imaging Reporting and Data System, Systematized Nomenclature of Medicine). All unique routes through all CDTs were counted to measure the degree of data-based personalization of recommendations.

RESULTS

In total, 60 CDTs were necessary to cover the whole guideline and were driven by 114 data items. Data items originated from pathology (49%), radiology (27%), clinical (12%), and multidisciplinary team (12%) reports. Of all data items, 101 (89%) could be classified by existing classification and coding systems. All 60 CDTs could be integrated in an interactive decision support app that contained 376 unique patient subpopulations.

CONCLUSION

By defining data items unambiguously and unequivocally and coding them to an international coding system, it was possible to present a complex guideline as systematically constructed modular data-driven CDTs that are clinically interpretable and accessible in a decision support app.

Published: May 2019

The ventricular-subventricular zone (V-SVZ) of the forebrain is the source of neurogenic stem/precursor cells for adaptive and homeostatic needs throughout the life of most mammals. Here, we report that Suppressor of Fused (SUFU) plays a critical role in the establishment of the V-SVZ at early neonatal stages by controlling the proliferation of distinct subpopulations of stem/precursor cells. Conditional deletion of Sufu in radial glial progenitor cells (RGCs) at E13.5 resulted in a dramatic increase in the proliferation of Sox2+ Type B1 cells. In contrast, we found a significant decrease in Gsx2+ and a more dramatic decrease in Tbr2+ transit amplifying cells (TACs) indicating that innate differences between dorsal and ventral forebrain derived Type B1 cells influence Sufu function. However, many precursors accumulated in the dorsal V-SVZ or failed to survive, demonstrating that despite the over-proliferation of Type B1 cells, they are unable to transition into functional differentiated progenies. These defects were accompanied by reduced Gli3 expression and surprisingly, a significant downregulation of Sonic hedgehog (Shh) signaling. Therefore, these findings indicate a potential role of the Sufu-Gli3 regulatory axis in the neonatal dorsal V-SVZ independent of Shh signaling in the establishment and survival of functional stem/precursor cells in the postnatal dorsal V-SVZ.
Eyes and negative phototaxis in juvenile crown-of-thorns starfish, Acanthaster species complex
Authors: Korsvig-Nielsen Camilla , Hall Mike , Motti Cherie , Garm Anders
Published: May 2019

As a corallivore, the Crown-of-Thorns Starfish (COTS; Acanthaster species complex), has significant impacts on coral mortality and community structure on tropical reefs throughout its Indo-Pacific range. COTS form aggregations which systematically move through and across reefs causing significant loss in hard coral cover. Previous work has shown that their behaviours on the reef are influenced by rheotaxis, olfaction, and vision, with vision guiding adult animals to their coral habitat at short distances. As the compound eye of starfish grows throughout life the visual capacity of juvenile eyes is putatively less than for adult animals. Here we show this to be the case. Juvenile eyes have approximately the same visual field as adult eyes but significantly lower spatial resolution. They display negative phototaxis, as observed in adults, but we found no direct proof for the use of spatial resolution in this behaviour. Our results show that juveniles are able to use their eyes to locate their habitat, the coral reef, however, their putatively lower spatial resolution would make this visual task more difficult than for the adults.
FT-IR/NIR Spectroscopic Study of Interactions between Water and Alkylamines
Authors: Iwamoto Reikichi
Published: May 2019

In the present paper we have studied interactions of the N and NH of alkylamines with water. We analyzed the property from the infrared and near-infrared absorptions that hydration causes to tributylamine (TBA) ((Bu)3N) and dibutylamine (DBA) ((Bu)2NH or (Bu)2HN) in the neat liquid or their solutions in heptane at varying concentrations. It has been found that the amine N of TBA very strongly interacts with water and forms the complex (Bu)3N⋯Hb-O-Hf (OHb: bonded OH, OHf: free OH) which is partly dissociated into (Bu)3NH+ and OH− at equilibrium. DBA retains an NH and may act not only as a proton acceptor but also a proton donor to water. Correspondingly, it has been found, the NH is hydrogen-bonded partly through the N to form the strongly-bound complex (Bu)2HN⋯Hb-O-Hf and partly through the H to form the complex (Bu)2NH⋯OH2. From their associated spectral features we propose that the former is partly dissociated into (Bu)2NH2+ and OH− at equilibrium as in the case of TBA and the latter is rather stabilized to be a larger cluster such as (Bu)2NH⋯OH2·(H2O)m.

Published: May 2019

Single-cell RNA sequencing (scRNA-seq) has emerged as a popular method to profile gene expression at the resolution of individual cells. While there have been methods and software specifically developed to analyze scRNA-seq data, they are most accessible to users who program. We have created a scRNA-seq clustering analysis GenePattern Notebook that provides an interactive, easy-to-use interface for data analysis and exploration of scRNA-Seq data, without the need to write or view any code. The notebook provides a standard scRNA-seq analysis workflow for pre-processing data, identification of sub-populations of cells by clustering, and exploration of biomarkers to characterize heterogeneous cell populations and delineate cell types.
Emerging ideas and tools to study the emergent properties of the cortical neural circuits for voluntary motor control in non-human primates
Authors: Kalaska John F.
Published: May 2019

For years, neurophysiological studies of the cerebral cortical mechanisms of voluntary motor control were limited to single-electrode recordings of the activity of one or a few neurons at a time. This approach was supported by the widely accepted belief that single neurons were the fundamental computational units of the brain (the “neuron doctrine”). Experiments were guided by motor-control models that proposed that the motor system attempted to plan and control specific parameters of a desired action, such as the direction, speed or causal forces of a reaching movement in specific coordinate frameworks, and that assumed that the controlled parameters would be expressed in the task-related activity of single neurons. The advent of chronically implanted multi-electrode arrays about 20 years ago permitted the simultaneous recording of the activity of many neurons. This greatly enhanced the ability to study neural control mechanisms at the population level. It has also shifted the focus of the analysis of neural activity from quantifying single-neuron correlates with different movement parameters to probing the structure of multi-neuron activity patterns to identify the emergent computational properties of cortical neural circuits. In particular, recent advances in “dimension reduction” algorithms have attempted to identify specific covariance patterns in multi-neuron activity which are presumed to reflect the underlying computational processes by which neural circuits convert the intention to perform a particular movement into the required causal descending motor commands. These analyses have led to many new perspectives and insights on how cortical motor circuits covertly plan and prepare to initiate a movement without causing muscle contractions, transition from preparation to overt execution of the desired movement, generate muscle-centered motor output commands, and learn new motor skills. Progress is also being made to import optical-imaging and optogenetic toolboxes from rodents to non-human primates to overcome some technical limitations of multi-electrode recording technology.
Brexanolone, a neurosteroid antidepressant, vindicates the GABAergic deficit hypothesis of depression and may foster resilience
Authors: Lüscher Bernhard , Möhler Hanns
Published: May 2019

The GABAergic deficit hypothesis of depression states that a deficit of GABAergic transmission in defined neural circuits is causal for depression. Conversely, an enhancement of GABA transmission, including that triggered by selective serotonin reuptake inhibitors or ketamine, has antidepressant effects. Brexanolone, an intravenous formulation of the endogenous neurosteroid allopregnanolone, showed clinically significant antidepressant activity in postpartum depression. By allosterically enhancing GABAAreceptor function, the antidepressant activity of allopregnanolone is attributed to an increase in GABAergic inhibition. In addition, allopregnanolone may stabilize normal mood by decreasing the activity of stress-responsive dentate granule cells and thereby sustain resilience behavior. Therefore, allopregnanolone may augment and extend its antidepressant activity by fostering resilience. The recent structural resolution of the neurosteroid binding domain of GABAAreceptors will expedite the development of more selective ligands as a potential new class of central nervous system drugs.
Sleep monitoring with the Apple Watch: comparison to a clinically validated actigraph
Authors: Roomkham Sirinthip , Hittle Michael , Cheung Joseph , Lovell David , Mignot Emmanuel , Perrin Dimitri
Published: May 2019

Background: We investigate the feasibility of using an Apple Watch for sleep monitoring by comparing its performance to the clinically validated Philips Actiwatch Spectrum Pro (the gold standard in this study), under free-living conditions.

Methods: We recorded 27 nights of sleep from 14 healthy adults (9 male, 5 female). We extracted activity counts from the Actiwatch and classified 15-second epochs into sleep/wake using the Actiware Software. We extracted triaxial acceleration data (at 50 Hz) from the Apple Watch, calculated Euclidean norm minus one (ENMO) for the same epochs, and classified them using a similar algorithm. We used a range of analyses, including Bland-Altman plots and linear correlation, to visualize and assess the agreement between Actiwatch and Apple Watch.

Results: The Apple Watch had high overall accuracy (97%) and sensitivity (99%) in detecting actigraphy-defined sleep, and adequate specificity (79%) in detecting actigraphy defined wakefulness. Over the 27 nights, total sleep time was strongly linearly correlated between the two devices (r=0.85). On average, the Apple Watch over-estimated total sleep time by 6.31 minutes and under-estimated Wake After Sleep Onset by 5.74 minutes. The performance of the Apple Watch compares favorably to the clinically validated Actiwatch in a normal environment.

Conclusions: This study suggests that the Apple Watch could be an acceptable alternative to the Philips Actiwatch for sleep monitoring, paving the way for larger-scale sleep studies using Apple’s consumer-grade mobile device and publicly available sleep classification algorithms. Further study is needed to assess longer-term performance in natural conditions, and against polysomnography in clinical settings.
Access to contraceptives for adolescents in northern Nigeria – a cross-sectional study from three secondary health facilities in Kaduna metropolis, Kaduna
Authors: Alayande Audu , Bello-Garko Bahijjatu , Umeh Gregory , Nuhu Islamiyat
Published: May 2019

Background: In 2015, the United Nations Development Programme (UNDP) noted that countries will need to meet the increasing demand for contraceptives by the over 600 million 15- to 19-year-olds around the world. Although the unmet need for contraception for Women of Child Bearing Age (WCBA) in Nigeria is 12.7%, the value is higher (35.3%) among adolescents aged 15 – 19 years. Additionally, the unmet need for family planning (FP) among WCBA in Kaduna state is 5.8%, with 33.3% of women aged 20-24 years in Kaduna reported to have had a live birth before the age of 18 years. This study sought to evaluate adolescent contraceptive use in three referral health facilities of Kaduna metropolis.

Methods: This is a descriptive cross-sectional desk review of 5543 FP clients that attended three referral centers between 2014 and 2016. Data on their age, parity and the use of contraceptives were collected from the clinic registers and analyzed using SPSS 22.

Results: The FP client age ranged from 12 to 57 years, of which only 3.6% were adolescent. The annual proportion of adolescent contraceptive users ranged from 3.1 – 4.1%. More than 96% of the adolescents had given birth to at least one child. Around 62% of the adolescents used injectable contraceptives but there was no IUD use reported by any adolescent.

Conclusions: The low proportion of adolescent contraceptive users and their limited choice of contraceptive methods, emanating from multiplicity of client and provider bias, calls for innovative interventions to meet the contraceptive needs of adolescents.

A Matter of Perspective: How Failure Shapes Distributive Preferences
Authors: Cassar Lea , Klein Arnd H.
Published: May 2019

People vary in what they view as a fair distribution of earnings in organizations and, more generally, society. Where do these different views originate? We study the question of whether the experience of failure or success in a winner-take-most competition shapes people’s perspectives about distributive justice. In a laboratory experiment, subjects generated a high or low income either through a lottery or through a performance-based tournament. A subset of subjects could then redistribute the income of another subset of subjects. We find that the tournament losers redistribute significantly more than all of the other distributors when the inequality is generated by the tournament, whereas the lottery losers redistribute significantly more than all of the other distributors when the inequality is generated by the lottery. The effect still holds when controlling for potential self-selection into different outcomes of the tournament. We replicate the results in a second experiment and show that the underlying psychological mechanisms include an in-group bias and a self-serving bias in responsibility attribution. These findings have implications for the design of compensation schemes in organizations and for public policies in general.

Disguised compliance or undisguised nonsense? A critical discourse analysis of compliance and resistance in social work practice
Authors: Leigh Jadwiga , Beddoe Liz , Keddell Emily
Published: May 2019

This article examines how the term ‘disguised compliance’ first emerged and developed into the popular catchphrase that is used in practice today. Using critical discourse analysis, we explore how language affects practice and how social workers draw on a predetermined concept to rationalise concerns relating to parental resistance. We contend that concepts such as disguised compliance are misleading as they do not improve social workers’ abilities in detecting resistance or compliance. Instead, we argue that social workers should be cautious when using popular mantras which, on the surface, appear effective in describing parents’ behaviours but, in reality, conceal concerns relating to risk, accountability and blame. This study differs from the current literature that advocates social workers should be aware of disguised compliance by shifting the emphasis away from the behaviours of parents and towards acknowledging the power such discursive activities can have on practice.
Surveillance of the equine infectious anemia virus in Eastern and Central Saudi Arabia during 2014-2016
Authors: Alnaeem Abdulmohsen Abdullah , Hemida Maged Gomaa
Published: May 2019

Background: Equine infectious anemia virus (EIAV) is one of the most important threats to the equine industry globally. This is due to the poor performance of the affected horses, which requires euthanization of the infected animals upon the infection confirmation. Infected animals remain carriers throughout their life. EIAV infection has been reported in many parts of the world, including North America, Europe, Asia, and Africa. However, the EIAV status is never assessed in horses in the Gulf area, especially in the Kingdom of Saudi Arabia (KSA).

Aim: This study aimed to perform molecular and serological surveillance among some horse populations in Eastern and Central Saudi Arabia.

Materials and Methods: Sera and whole blood were collected from 361 horses and 19 donkeys from the eastern and central regions of Saudi Arabia during January 2014-December 2016. Sera were tested by the commercial EIAV enzyme-linked immunosorbent assay kits. Moreover, the collected blood samples were tested by the commercial real-time polymerase chain reaction kits.

Results: Our serological surveillance revealed the absence of any antibodies against EIAV in the tested animals. Similar results were reported for the tested horses' plasma. This study confirms the absence of EIAV in horses and donkeys from Eastern and Central Saudi Arabia during the tenure of the current study. However, careful monitoring of the EIAV is highly recommended to avoid the emergence of such a virus in the horse population in Saudi Arabia.

Conclusion: To the best of our knowledge, this is the first EIAV surveillance conducted not only in Saudi Arabia but also in the Gulf area. This study confirms the absence of EIAV in the tested equine population in the eastern and central regions of Saudi Arabia during 2014-2016.
Direct Instantaneous Torque Control of the Switched Reluctance Motor for Electric Vehicles Applications Using Fuzzy Logic Control
Authors: Abdel-Fadil Reyad Mohamed , Számel László
Published: May 2019

This paper presents direct torque control of Switched Reluctance Motor (SRM) using Fuzzy Logic Control (FLC) for electric vehicles applications. The PD-FLC is proposed for SRM torque control, to keep the torque of the motor shaft in tracking the reference torque with high accuracy. With the help of FLC techniques, the SRM torque ripples can be reduced compared to traditional control techniques. In this study, the nonlinear 6/4 SRM model is simulated with the symmetrical converter, and the converter controller is programmed using C-language. The proposed method is tested at different load and variable speed conditions, and the obtained results confirm that the FLC direct torque control can be used for torque control to improve the motor performance and reduce the torque ripples compared to other techniques such as direct instantaneous torque control.

Published: May 2019

Cone penetration in-situ tests are commonly used to measure the cone index of the soils. This measurement process can be modelled very well with Discrete Element Method (DEM) if the parameters of the correct contact model are defined properly. In this paper the Hertz-Mindlin with bonding contact model are used and the effect of the properties of this contact model on soil’s penetration resistance is investigated. Our aim was to determine those contact parameters which play important role in the penetration process, thus are necessary to take into account while calibrating the discrete element soil model to the results of real penetration tests.

Arni Kartikaningtyas, Eko Ariyanto, in this paper explain that In electric power transmission and distribution, volt-ampere reactive (var) is the unit used to measure reactive power into AC electric power system. Reactive power in AC circuits when current and voltage are not in phase. Is a true symbol and Var, var, or VAR, but all three terms are widely used. Var terms proposed by Romanian Constantin Budeanu electrical engineer and was introduced in 1930 by the IEC in Stockholm, which has been adopted as a unit for reactive power. Var can be regarded as both the imaginary part of the apparent power, or the power flowing to the load reactive, where voltages and currents specified in volts and amperes. Two definitions are equivalent. Reactive power into the power unit kVArh is used by passive components beyond resistor which is a power loss or power that is not desirable. This power to a minimum to avoid, or at least minimized, although it will not disappear altogether, by minimizing the power factor. Industrial customers are groups of customers with the use of induction machines used for the induction process that requires a great power to drive the motor and pull out the reactive power usage needs to be taken into account. Customers I 2 is the class of tariffs for industrial purposes being at low voltage with power above 14 kVA to 200 kVA. Keywords: VAR, customer Industry.

Dewantara, Priyo Sasmoko, in this paper explain that a measuring instrument is a tool used by humans to help determine parameters such as height and weight. Most height and weight gauges used today still use simple and still conventional equipment. In addition, if manually, there are still frequent measurement errors that come from the measuring instrument itself or from the human. This happens because of inaccuracies in reading measuring instruments that lack precision or perhaps from the human factor itself. The purpose of this study was to create a digital height and weight automation system accompanied by displaying its ideal weight based on height. This system is built using Arduino as a system controller. The ultrasonic sensor is used as a measure of height. Load cell is used as a measure of weight. And a 20x4 LCD to display the output. From testing and analyzing the results of measurements of height according to the actual height, the results of measurements of weight have an error percentage of 0.53% - 2.77%. The system determines the ideal or not body weight based on BMI. Keywords: 20x4 LCD, Load Cell Sensor, Arduino.ReferencesFogaswara, Eka. 2013.

RANCANG BANGUN EXTERNAL ELECTROMAGNETIC RETARDERS SYSTEM PADA MOTOR 1 PHASA
Authors: Dewantara Bima Dicky Anugrah , Manan Saiful
Published: May 2019

Bima Dicky Anugrah Dewantara, Saiful Manan, in this paper explain that Electromagnetic retarders are generally known as electromagnetic inhibitors or brakes, the braking system eliminates most braking mechanics, thereby reducing conventional braking systems. Safety requirements and safety systems are developed and become a focal point of an equipment. Electromagnetic brakes are a safety component with a control system that is easy to control. With this electromagnetic brake, it will reduce maintenance costs, because it only requires a factor of electricity to be able to move it. The braking system uses electromagnetic forces to slow down a movement, which is generally a shaft motion. A dish with non-ferromagnetic metal material is attached to a rotating shaft. The disk is flanked by the side of the stator in the form of an electromagnetic coil system that can generate a magnetic field from electricity. Electric current generates a magnetic field in the coil. And the metal plate that cuts the magnetic field will cause eddy currents on the disk itself. This eddy current will generate a magnetic field whose direction is opposite to the previous magnetic field, thus inhibiting the rotary motion of the shaft. In designing, experimenting and making an External Electromagnetic Retarders System Design on 1 Phase Motor, use the NE 555 IC as the control duty cycle. So that the relationship between braking current and braking time is inversely proportional if the higher the current, the shorter the time it takes for the rotor to stop. And the relationship between braking current and motor current is directly proportional, by increasing the braking current will increase the load on the motor causing the motor current to increase. Keywords: Electromagnetic Retarders, Electromagnetic Brakes, Eddy Flow EffectReferencesTipler, P. 2008.

RANCANG BANGUN PROTOTIPE SISTEM KENDALI IRON REMOVAL FILTER (IRF) PADA UNIT PENGOLAHAN AIR BERSIH BERBASIS PLC
Authors: Karyadi Kukuh , Suseno Jatmiko Endro
Published: May 2019

Kukuh Karyadi, Jatmiko Endro Suseno in this paper explain that Water is a necessity of life that is very important for mankind. The availability of clean water has been sought to be fulfilled in various ways. One of them is by making a clean water treatment plant that can process water that is not yet suitable for consumption to be more feasible and ready to be consumed for everyday life. The operation of water treatment plant is still manually operated such as in the Iron Removal Filter (IRF) control system so that the processing is not easy to operate. To facilitate the operation of a clean water treatment unit, a control system based on a Programmable Logic Controller (PLC) is created on the Iron Removal Filter (IRF) processing unit. Control system consisting of PLC, relay circuit, power supply and Human Machine Interface (HMI), works to control the clean water processing unit including controlling the process on the IRF automatically. Also made a prototype of a water treatment plant consisting of an aerator unit, an IRF unit, a storage tank, several pumps and several control valves to be controlled by the control system in operation. The control system uses PLC as a control center because PLC is a controller that is simple, easy to program and very reliable as already widely used in the industrial world. The PLC brand used is Omron because it is cheap, reliable and has software named CX-Programmer which is easy in programming. The control system uses laptop computer as an HMI in the operation. HMI uses VTScada software and is connected to a PLC using OPC CX-Server software. The control system that is made can control the clean water processing unit in the form of a prototype.

Latar belakang : Tindakan operasi akan menyebabkan terjadinya suatu respon stres. Stres yang timbul dapat merupakan stres psikologi, stres anestesi dan stres pembedahan. Pasien yang akan menjalani operasi elektif seringkali mengalami kecemasan preoperasi, suatu keadaan stres psikologi yang dapat mengaktivasi sistem neuroendokrin dan inflamasi. Kecemasan yang dialami pasien dapat menimbulkan masalah yang signifikan dalam manajemen pasien. Ketidakstabilan hemodinamik, stimulasi otonom dan endokrin dapat memperburuk kondisi metabolik akibat operasi. Tujuan : Untuk mengetahui pengaruh minuman karbohidrat terhadap kadar glukosa darah dan tingkat kecemasan preoperasi pasien.Metode : Jenis penelitian adalah uji klinis eksperimental acak tersamar ganda. Sampel diambil secara consecutive sampling sebanyak 30 pasien dengan ASA I dan II,  kemudian dibagi menjadi dua kelompok yaitu kelompok kontrol yang menjalani puasa malam hari dan kelompok perlakuan yang mendapatkan minuman karbohidrat 12,5% 400ml 2-3 jam preoperasi. Penilaian tingkat kecemasan dan pengukuran kadar glukosa darah dilakukan di ruang premedikasi kamar operasi. Data yang diperoleh akan dianalisis menggunakan analisa jalur.Hasil : Minuman karbohidrat memiliki pengaruh yang signfikan (p<0,05) terhadap penurunan tingkat kecemasan preoperasi pasien dengan koefisien jalur sebesar -0,771. Pengaruh perubahan kadar glukosa darah tidak menunjukkan hasil yang signifikan (p>0,05) terhadap penurunan tingkat kecemasan preoperasi pasien dengan koefisien jalur sebesar -0,173.Kesimpulan : Pemberian minuman karbohidrat menurunkan tingkat kecemasan preoperasi pasien secara signifikan. Sedangkan perubahan kadar glukosa darah tidak memiliki pengaruh yang signifikan terhadap penurunan tingkat kecemasan preoperasi pasien dan tidak menambah pengaruh penurunan tingkat kecemasan oleh minuman karbohidrat.

Electronic equipment is produced to meet human needs, so this will also have a significant impact on increasing the rate of e-waste generation in landfills in almost all countries. One of the environmental pollution issues that are of concern throughout the world is the management of e-waste (e-waste). This is due to the rapid increase in the use of electronic products. Thus, the existence of electrical and electronic equipment becomes shorter and becomes obsolete. The absence of information related to the volume of e-waste generation and material flow is one of the problems of the Indonesian government in managing e-waste. Therefore, the purpose of this paper is to calculate e-waste and analyze material flow. The method used in this study is Material Flow Analysis (MFA). Furthermore, a survey of household and informal sector respondents was used. The questionnaire adopted from UNEP was modified and distributed to 400 households and 54 informal sectors in DKI Jakarta. The results show the total rate of generation of e-waste produced aaproximately 7713.42013 kg/year. Furthermore, it is necessary to develop several strategies in order to avoid negative impact. This research can be information in filling the data limitations and management of sustainable e-waste in DKI Jakarta.

The coastal zone of Losari Beach is located in a strategic position and rich in potential coastal resources, but the high density of human activities has decreased the quality of the surrounding waters.This study aimed to examine water quality based on meiofauna abundance and pollution index in the coastal zone of Losari Beach, Makassar. It employed a quantitative descriptive approach with purposive sampling method. The identified total meiofauna abundance was117,176 individuals/m2consisting of 138 species from 13 phyla. Ostracoda, olygochaeta, sarcomastigophora, ciliophora, and polychaetawere phyla with the highest abundance because of their high adaptability to polluted aquatic conditions. Meanwhile, tardigrada and aelosomatidaewere found in very low abundance because both phyla only thrive in pollution-free environments and have a pattern of high migration flow from one habitat to another. As for aelosomatidae, the habitat of its speciesis limitedto brackish or saline waters. A good-quality aquatic environment is a habitat for all benthic organisms and enables their even distribution. It explains the discovery of true and temporary meiofauna with uniform or even compositions in the bottom of the waters. The waters in the coastal zone of Losari Beach are heavily polluted. The stationslocated around the traditional Paotere harbor, hotels, restaurants, Losari Beach Platforms, the waste disposal outlets of Stella Maris Hospital, Fort Rotterdam canals, and Jeneberang River mouthhad very high pollution index. Some of these stations had low meiofauna abundance levels, and the poor water quality in their surroundings was caused by anthropogenic activity. Even though the area around TanjungMerdeka Beach had relatively low pollution index, it was categorized as severely contaminated because the index score was >10.
