This work investigates the removal of cyanide as a noxious pollutant in the gold processing effluent (Aq-Dara mine, Takab, Iran) using H2O2, H2O2+Fe(II) (Fenton), H2O2+Cu(II), NaClO and Ca(ClO)2 oxidants. Implementation of purification operation was carried out by varying the parameters including pH, oxidant dosage, temperature and time of the reaction. The results show that the oxidants have the highest efficacy at pH 10-12, while the Fenton process has the highest efficiency at pH 8. The results confirm that Ca(ClO)2 is the best oxidant due to the shorter time, low reaction rate, high degradation of cyanide and low cost. The obtained results of response surface methodology optimization show that cyanide degradation has a direct relation to temperature, amount of oxidant, time and catalyst dosage parameters and has an inverse relation to pH. Also, the cyanide elimination efficiency is more than 99.5% and residual cyanide less than Environmental Protection Agency standards and 40% of the consumed water can be compensated by the effluent treatment and its return to the factory's processing circuit. Keywords: Oxidation Process; Gold Processing Effluents Treatment; Cyanide Degradation; Non-linear Kinetic Modeling, Response Surface Method.
The European Parliament Elections and Czech Political Parties: Much Ado About Nothing?
Authors: Mocek Ondřej , Petlach Martin , Hudečková Zuzana
Published: July 2020

The paper inquires divergences in electoral programs of four Czech political parties (the ČSSD, KDU-ČSL, KSČM, and the ODS) as delivered for all the previous European Parliament elections. The aim of this study is to compare the use of national and European themes as delineated in programs. It is assumed that, in many cases, the programs contain topics and aspects which are specific and valid for elections on the national level instead. Thus, the paper elaborates on one of the characteristics of the second-order elections theory as exemplified in the Euro-elections. Results of the analysis showed a significant superiority of national affairs over the European issues in the examined samples. Although the number of political parties varies in individual periods, the study has also confirmed the assumption drawn from the theory of second-order elections. Therefore, political parties utilize political programs for the European Parliament elections as of national interest with domestic affairs, not European. Furthermore, the study considers dissimilarities among political parties in positive and negative attitudes toward the EU. Hence, sundry approaches to European affairs may be identified across the Czech political parties.
Post-Soviet Revolutions and Post-Revolution Discourses: Explaining the Construction of Political Identities in Post-Rose Revolution Georgia and Post-Velvet Revolution Armenia
Authors: Terzyan Aram
Published: July 2020

The 2018 “Velvet Revolution” in Armenia has renewed scholarly interest in post-Soviet revolution studies. This paper explores the core narratives underlying post-Rose Revolution and post-Velvet Revolution identity construction in Georgian and Armenian political discourses. More specifically, it examines the core narratives employed by the Georgian and Armenian revolution leaders Mikheil Saakashvili and Nikol Pashinyan in constructing the political identities of “New Georgia” and “New Armenia.” The findings suggest that the core narratives dominating Saakashvili’s discourse on post-revolution Georgia are as follows: “democratic Georgia” and “laboratory of democratic reforms,” “stereotype breaker,” “European Georgia,” “peaceful Georgia,” “powerful Georgia” and “security contributor,” determined to homecoming to Europe. Pashinyan’s discourse has revolved around the notion of “proud Armenians,” who established “people’s government” capable of carrying out an “economic revolution.” In contrast to Saakashvili’s emphasis on escaping post-Soviet geopolitical space and gaining centrality in the EU-driven socio-political order, Pashinyan’s discourse does not suggest foreign policy U-turns. It concludes that while the 2003 “Rose Revolution” marked fundamental shifts in self-other conceptions within the Georgian political discourse, the post-revolution Armenian discourse has not experienced dramatic identity-driven transformations.

Published: July 2020

Background: The outbreak of the new coronavirus disease (COVID-19) imposes a considerable psychological burden on the medical staff working in central hospitals for COVID-19. In this systematic review, we will discuss the Prevalence and the risk factors of anxiety disorder among the frontline medical staff dealing with COVID-19 patients. Methods: PubMed, Scopus, Embase, Web of Science databases systematically searched from December 1, 2019, to April 30, 2020, for related published articles. In all electronic databases, the following search strategy implemented, and these keywords (in the title/abstract) used: "COVID-19" OR "novel Coronavirus" AND "anxiety" OR "psychology" OR "psychiatry" OR "psychological distress" AND "nurses" or "clinicians." We included only the cross-sectional studies. Results: Through the search strategy, we could identify eight related cross-sectional articles about anxiety among the healthcare workers in central hospitals for COVID-19 infection. However, the authors scanned the reference lists of the included studies and identified multiple references. According to our findings, the frontline medical staff are at risk of developing an anxiety disorder, which is mainly mild. Additionally, female nurses are more susceptible to experience anxiety during the COVID-19 pandemic. Conclusion: Regarding the outbreak of COVID-19 worldwide and the workload of the frontline medical staff dealing with COVID-19 patients, particular attention should be given on the mental health of the healthcare provides.

Authors: Dhameliya Jignesh Dhirubhai , Chandra Umesh Kumar , Vishwakarma Sumit Kumar , Ganganpalli Dattaprasad , Verma Archana
Published: July 2020

Background: It is suggested that there is a positive association between vitamin D deficiency and benign paroxysmal positional vertigo (BPPV). We suggest, as a hypothesis, there is a positive association between vitamin D deficiency and BPPV. The current study aimed to investigate the association between vitamin D levels and BPPV. Methods: The present observational case-control study was planned and conducted on 100 participants (50 cases and 50 controls) in the Department of Neurology, Choithram Hospital & Research Center (CHRC), Indore, MP, India, from January 2018 to December 2018. All consecutive patients with diagnosis of idiopathic BPPV who were above the age of 18 years with a negative neurological status were included. Analyses were performed using SPSS software version 10. Results: BPPV was more common among those aged 50 to 70 years (64%). Out of 100 participants, 72 (72%) had vitamin D deficiency, in which 40 (80%) were cases and 32 (64%) were controls. 32 (64%) patients had posterior canal involved, out of them 20 (40%) were females and 12 (24%) were males, and in both groups posterior canal was more involved. Canal involvement according to gender was not statistically significant (P value=0.45). Mean vitamin D level for cases and controls was 34.9 and 46.5 nmol/L, respectively, and this difference was statically very significant with a p-value of 0.01 (P value < 0.05). Conclusion: According to the findings, there is a statistically significant association between vitamin D3 deficiency and Idiopathic BPPV. It can be noted that vitamin D3 deficiency may be a risk factor for the BPPV.

Introduction: Stroke is one of the most devastating neurologic conditions in the world. Despite all the efforts that have been made for effective treatment, the prevalence of this medical condition is still high. One of the new methods in the treatment of patients is the use of low power laser and pulsed magnetic fields. The previous studies investigated the effectiveness of these methods individually. However, the present study aimed to investigate their effectiveness in combination. Methods: We divided the patients into control (n=26) and experimental (n=26) groups. The primary variables included the Mini-Mental State Examination (MMSE) and the National Institute of Health Stroke Scale (NIHSS). The experimental group received extremely low-frequency electromagnetic field (EMF-ELF) treatment with 1 mT power and laser in rejection with a wavelength of 840 nm for 5 days and 45 min/d. Results: The variable measured during this study, in addition to comparing the results of the intervention between the control and experimental groups, showed a significant difference in all indicators before and after the intervention. The mean and standard deviations of the modified Rankin scale (mRS), functional status (Barthel’s index), and cognitive status (MMSE) (P<0.001) were signed between 2 groups. Conclusion: Laser and magnetic field combination can be effective in the treatment of stroke. Further studies are recommended to ensure a better comparison.

Published: July 2020

Background: Glioblastoma multiforme (GBM) is the most type of brain malignancy in adults. Radical excision surgery, chemotherapy, and radiotherapy in some cases are still unsuccessful, and most patients with GBM die within 3 to 6 months following diagnosis. Botulinum toxin type A (BtxA) has cellular toxin effects and suppresses the cell division of certain types of cancer cell lines in vivo and in vitro study. The present study designed to evaluate the apoptotic effect of BtxA on the GBM cell line. Methods: U87-MG GBM cell line cultured according to the routing protocols, divided into 2 groups including, trial (BtxA treated) and control groups. Cells of the trial group exposed to different doses of BtxA. The cell viability, cycle arrest, and pro-apoptotic proteins evaluated respectively by MTT assay, subG1, and Western blotting. Results: MTT assay showed that the viability of the BtxA treated cells at doses of 1.45 Unit and other doses after 24 to 48 hours, significantly decreased (P<0.001) compared to the control groups. Apoptosis percentage of the subG1 test also indicated that 1.45 unit dose significantly increased in the cells exposed to BtxA compared to the control group in 24 hours. The expression of P53 and caspase 3 proteins indicated a significant increase. Conclusion: BtxA induces apoptosis in U87-MG cell line via p53 and caspase 3 pathways and could have clinical applications. In vivo studies need to confirm the clinical application of the present findings.
The Effective Brain Areas in Recognition of Dyslexia
Authors: Kheyrkhah Shali Roya , Setarehdan Seyed Kamaledin
Published: July 2020

Background: The brain has four lobes consist of frontal, parietal, occipital, and temporal. Most researchers have reported that the left occipitotemporal region of the brain, which is the combined region of the occipital and temporal lobes, is less active in children with dyslexia like Sklar, Glaburda, Ashkenazi and Leisman. Methods: There are different methods and tools to investigate how the brain works, such as magnetic resonance imaging (MRI), positron emission tomography (PET), magneto-encephalography (MEG) and electroencephalography (EEG). Among these, EEG determines the electrical activity of the brain with the electrodes placed on the special areas on the scalp. In this research, we processed the EEG signals of dyslexic children and healthy ones to determine what the areas of the brain are most likely to cause the disease. Results: For this purpose, we extracted 43 features, including relative spectral power (RSP) features, mean, standard deviation, skewness, kurtosis, Hjorth, and AR parameters. Then an SVM classifier is used to separate two classes. Finally, we show the particular brain activation pattern by calculating the correlation coefficients and co-occurrence matrices, which suggests the activation of the working memory region as an active area. Conclusion: By identifying the brain areas involved in reading activity, it has expected that psychologists and physicians will be able to design the therapeutic exercises to activate this part of the brain.

Authors: Dinh Thi Phuong Hoai , Mai Dang Thi , Truong Van Tri
Published: July 2020

Instruction: The current study reports a woman with pituitary adenoma and frontal convexity meningioma that was detected accidentally. To the best of our knowledge, this case is considered as a rare clinical scenario. Case Presentation: A 37 years old woman suffering from amenorrhea and galactorrhea had her detail investigation showed hyperprolactinemia. The patient was diagnosed with a prolactinoma, and a frontal convexity meningioma was discovered on magnetic resonance imaging (MRI). The prolactinoma controlled with Bromocriptine therapy, while the meningioma monitored through medical observation. After two months of pharmaceutical medication, her symptoms improved with the decrease in serum prolactin. Conclusion: Thanks to sophisticated MRI techniques, meningioma and prolactinoma were incidentally detected. It should be noted that co-morbidity of prolactinoma and meningioma is very rare. The mechanism of the association between these two familiar types of intracranial tumors has not yet been clarified, which indicates the need for further studies to offer possible targeted treatment for patients.

Published: July 2020

Background: Cost is a major barrier to maternal health service utilisation for many women in low- and middle-income countries (LMICs). However, comparable evidence of the available cost data in these countries is limited. We conducted a systematic review and comparative analysis of costs of utilising maternal health services in these settings. Methods: We searched peer-reviewed and grey literature databases for articles reporting cost of utilising maternal health services in LMICs published post-2000. All retrieved records were screened and articles meeting the inclusion criteria selected. Quality assessment was performed using the relevant cost-specific criteria of the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist. To guarantee comparability, disaggregated costs data were inflated to 2019 US dollar equivalents. Total adjusted costs and cost drivers associated with utilising each service were systematically compared. Where heterogeneity in methods or non-disaggregated costs was observed, narrative synthesis was used to summarise findings. Results: Thirty-six studies met our inclusion criteria. Many of the studies costed multiple services. However, the most frequently costed services were utilisation of normal vaginal delivery (22 studies), caesarean delivery (13), and antenatal care (ANC) (10). The least costed services were post-natal care (PNC) and post-abortion care (PAC) (5 each). Studies used varied methods for data collection and analysis and their quality ranged from low to high with most assessed as average or high. Generally, across all included studies, cost of utilisation progressively increased from ANC and PNC to delivery and PAC, and from public to private providers. Medicines and diagnostics were main cost drivers for ANC and PNC while cost drivers were variable for delivery. Women experienced financial burden of utilising maternal health services and also had to pay some unofficial costs to access care, even where formal exemptions existed. Conclusion: Consensus regarding approach for costing maternal health services will help to improve their relevance for supporting policy-making towards achieving universal health coverage. If indeed the post-2015 mission of the global community is to "leave no one behind," then we need to ensure that women and their families are not facing unnecessary and unaffordable costs that could potentially tip them into poverty.
A Board Level Intervention to Develop OrganisationWide Quality Improvement Strategies: Cost-Consequences Analysis in 15 Healthcare Organisations
Authors: Barbosa Estela Capelas , Jones Lorelei , Pomeroy Linda , Robert Glenn , Burnett Susan , Anderson Janet E. , Morris Steve , Naomi Fulop
Published: July 2020

Background: Hospital boards have statutory responsibility for upholding the quality of care in their organisations. International research on quality in hospitals resulted in a research-based guide to help senior hospital leaders develop and implement quality improvement (QI) strategies, the QUASER Guide. Previous research has established a link between board practices and quality of care; however, to our knowledge, no board-level intervention has been evaluated in relation to its costs and consequences. The aim of this research was to evaluate these impacts when the QUASER Guide was implemented in an organisational development intervention (iQUASER). Methods: We conducted a ‘before and after’ cost-consequences analysis (CCA), as part of a mixed methods evaluation. The analysis combined qualitative data collected from 66 interviews, 60 hours of board meeting observations and documents from 15 healthcare organisations, of which 6 took part on iQUASER, and included direct and opportunity costs associated with the intervention. The consequences focused on the development of an organisation-wide QI strategy, progress on addressing 8 dimensions of QI (the QUASER challenges), how organisations compared to benchmarks, engagement with the intervention and progress in the implementation of a QI project. Results: We found that participating organisations made greater progress in developing an organisation-wide QI strategy and became more similar to the high-performing benchmark than the comparators. However, progress in addressing all 8 QUASER challenges was only observed in one organisation. Stronger engagement with the intervention was associated with the implementation of a QI project. On average, iQUASER costed £23 496 per participating organisation, of which approximately 44% were staff time costs. Organisations that engaged less with the intervention had lower than average costs (£21 267 per organisation), but also failed to implement an organisation-wide QI project. Conclusion: We found a positive association between level of engagement with the intervention, development of an organisation-wide QI strategy and the implementation of an organisation-wide QI project. Support from the board, particularly the chair and chief executive, for participation in the intervention, is important for organisations to accrue most benefit. A board-level intervention for QI, such as iQUASER, is relatively inexpensive as a proportion of an organisation’s budget.
Defining Delayed Discharges of Inpatients and Their Impact in Acute Hospital Care: A Scoping Review
Authors: Micallef Alexander , Buttigieg Sandra C. , Tomaselli Gianpaolo , Garg Lalit
Published: July 2020

Background: With the ever-increasing demand on acute healthcare, the hospital discharge process and delayed discharges are considered relevant in achieving optimal performance in clinical settings. The purpose of this paper is to review the literature to identify conceptual and operational definitions of delayed discharges, identify causes and effects of delayed discharges, and also to explore the literature for interventions aimed at decreasing the impact (in terms of reducing the number/rate of delays) of delayed discharges in acute healthcare settings. Methods: An extensive literature search yielded a total of 26 248 records. Sixty-four research articles were included in the scoping review after considering inclusion/exclusion criteria and the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) search strategy. The following databases were utilized: Cochrane, EBSCO, PubMed, PubMed Central, Medline, and Web of Science. The search was carried out between January 2017 and March 2020 and covered literature ranging from 1990 to 2019. Results were reviewed by authors for duplicates and filtered using the inclusion/ exclusion criteria. Tables were created to classify the chosen articles (n = 64), allowing us to organise findings and results. Results: Conceptual and operational definitions were analysed. In turn, causes and effects of delayed discharges were extracted and represented in diagrammatic format, together with specific interventions used in acute healthcare settings to lessen the effect of delayed discharges. Operational definitions of delayed discharges were found to be more difficult to establish, particularly in the light of the vast number of different scenarios and workplace interventions uncovered in the literature. The main causes of delayed discharges were faulty organisational management, inadequate discharge planning, transfer of care problems, and age. The main effects were bed-blocking, A&E (Accident & Emergency) overcrowding, and financial implications. The main interventions included ‘discharge before noon’ initiative, ‘discharge facilitation tools,’ ‘discharge delay tracking’ mechanisms, and the role of general practitioners and social care staff. Conclusion: This paper fills a gap in the fragmented literature on delayed inpatient discharges by providing a researchbased perspective on conceptual and operational definitions, causes and effects, as well as interventions to minimize their impact. The findings and definitions are intended as points of reference for future research.
Family’s Supportive Behaviors in the Care of the Patient Admitted to the Cardiac Care Unit: A Qualitative Study
Authors: Babaei Sima , Abolhasani Shahla
Published: July 2020

Introduction: A life-threatening illness can cause the involvement of family members and the imposition of psychological and physical stress on them. Certainly, the family is a very valuable resource in patient care and plays an important role in maintaining the emotional support and patient’s recovery. The aim of this study was to explain the family members’ supporting behaviors of the patient admitted to the cardiac special units. Methods: This qualitative study was performed in the cardiac special units in Isfahan. The number of participants was 20, including 5 nurses, 8 family members, and 7 patients. The data were collected through interview and observation by purposive sampling. Then, the data were analyzed by Graneheim and Lundman’s qualitative content analysis method. The study lasted 12 months. Results: Data analysis showed that family’s support can be classified into three levels, including support by the therapeutic alliance (attempts to console and reassure, restoration of selfesteem, diminishing patient’s insensitivity, commitment to the patient, and visiting the patient ), participatory information (obtaining reliable information from the nurse, active role in providing meaningful information about the patient’s prognosis), practical and instrumental support (searching for economic support resources, providing the patient with the necessary equipment, trying to do the right care taking into account the family culture). Conclusion: Understanding family’s supportive behaviors can help improve counseling and planning for quality care of patients admitted to the cardiac care units (CCUs).

Published: July 2020

Introduction: Hospitalization of patients in the intensive care units always has negative
consequences such as anxiety and concern for patients and their families. This study aimed to
investigate the effect of programmed family presence in intensive care units on patients’ and
families’ anxiety.
Methods: This was a quasi-experimental study conducted in Iran. The eligible patients and a
member of their families were assigned into two groups (N = 80) through convenience sampling.
The family members in the experimental group were allowed to attend twice a day for 15
minutes in a planned way beside the patient and contribute to their clinical primary care. In
the control group, the family members had a strict limitation to visit their patients based on the
usual policy. Anxiety in both groups at the beginning and on the third day of patient’s admission
was measured, using Spielberger’s questionnaire. The data were analyzed with SPSS version13.
Results: The mean score of anxiety in the control group did not show significant difference
in patients and in families, however it had decreased significantly in the experimental group
after the intervention for both patients and families. The results showed that mean differences
between the two groups was statistically significant in patients and families.
Conclusion: The planned presence of the family of patients in coronary care unit (CCU) played a
crucial role in reducing the anxiety of patients and their family. Furthermore, it is recommended
that strategies of visiting policy in intensive care units (ICUs) should be revised and the possibility
be provided for the families’ planned presence and participation in the patient care.
Love in Nursing: A Concept Analysis
Authors: Adib Hajbaghery Mohsen , Bolandian Shahnaz
Published: July 2020

Introduction: Professional nursing is based on caring. Care is a combination of love and respect
in interacting with others. There are many concerns about nursing care without love. However,
the concept and meaning of love in nursing have not been paid the due attention. This study
analyzed the concept of love in nursing. The aim of this study is to describe and discuss the
concept of love in nursing.
Methods: A concept analysis was conducted using the 8-step Walker and Avant’s model.
Databases such as SID, PubMed, Web of Science, CINHAL, SCOPUS and Google Scholar
were searched. The terms “love”,”concept analysis” and “nursing” were used for searching in
international sources. No time limit was considered in searching the databases and all studies
were published until December 2017. In the initial search, 142 articles were found but finally
eight articles remained relevant and entered the study.
Results: The authors did not find a special independent tool to measure love in nursing.
Therefore, we define love in nursing as follows: the combination of nursing care with a sense
of responsibility, benevolence, attention and concern, respect, and understanding of others as a
human being, regardless of their negative consequences for themselves.
Conclusion: Understanding the meaning of love in nursing can promote nursing practice in
two ways. First, the nurses are examining their values and beliefs. Second, they find out how to
interact with patients.

Published: July 2020

Introduction
: Literature has shown the effects of intravenous/intracoronary nicorandil on increased myocardial salvage in patients with ST-segment elevation myocardial infarction (STEMI) treated with mechanical reperfusion. However, the possible cardioprotective effect of oral nicorandil on the clinical outcome prior to primary coronary angioplasty is not well documented. Our aim was to assess the effect of oral nicorandil on primary percutaneous coronary intervention (PPCI). Methods: A total of 240 patients with acute STEMI undergoing PPCI were randomly assigned to oral nicorandil (Intervention, n=116) and placebo (Control, n=124) groups. The intervention group received 20 mg oral nicorandil at the emergency department and another 20 mg oral nicorandil in the catheterization laboratory just before the procedure. The control group received matched placebo. Our primary outcome was ST-segment resolution ≥50% one hour after primary angioplasty. Secondary outcome was in-hospital major adverse cardiovascular events (MACE), defined as a composite of death, ventricular arrhythmia, heart failure and stroke. Results: In the patients of intervention and control groups, the occurrence of ST-segment resolution ≥ 50% were 68.1% and 62.9% respectively, (P=0.27). In-hospital MACE occurred less frequently in the intervention group, compared to placebo group (11.2% vs. 22.5%, P=0.012). Conclusion: Although the administration of oral nicorandil before primary coronary angioplasty did not improve ST-segment resolution in patients with acute STEMI, its promoting effects was remarkable on in-hospital clinical outcomes.

Published: July 2020

Introduction:
Subclavian artery injury is an uncommon vascular trauma with potential morbidity and mortality. Management of subclavian artery trauma requires open and endovascular techniques and timely and efficacious decision is mandatory. We retrospectively reviewed traumatic subclavian artery injuries in a high-volume vascular surgery center in Iran. Methods: In a retrospective study, we assessed subclavian artery injuries during 6 years in ShohadaTajrish Medical Center. Background characteristics, type of incision, type of operation and outcome of patients were evaluated. Results: A total of 14 patients had subclavian artery injury (mean age 29.9 ± 13.4 years, 92.9% male). Trauma was in left and right sides in eight (57.1%) and six patients (42.9%) respectively. Arteriorrhaphy, interposition and ligation of injured artery was done in 7 (50.0%), 3 (21.4%) and 4 (28.6%) patients respectively. Associated nerve injury was present in six patients (42.9%). Endovascular proximal control was obtained in six patients (42.9%) prior to vascular exposure. Time of patient referral did not have significant association with shock or type of operation (P > 0.05). Conclusion: Although traumatic subclavian artery injuries are rare, its vascular exposures and reconstructions are of potential clinical concern. Endovascular interventions can facilitate proximal control. In addition, endovascular repair by covered stent is an alternative to open surgery.

The objective of this study was to develop a prebiotic beverage from yacon and pineapple sweetened with stevia. Nine functional beverage formulations were prepared. The yacon and the pineapple were incorporated in three proportions, P1: 30-70, P2: 50-50 and P3: 70-30, respectively. The selection of the optimal treatment was made by sensory analysis. The physicochemical analyzes of the optimal formulation evaluated were pH, acidity, total soluble solids, instrumental color and % Fructo oligosaccharides (FOS) (1-Kestose and Nystose). For the interpretation of results, a randomized design with a 3 x 3 factorial arrangement was used. Beverages P1 and P2, obtained the highest score on a scale of 9 points (p> 0,05); however, the latter had a higher percentage of FOS (0,19%). The beverage presented the following physicochemical characteristics, pH: 3,58 ± 0,03, Total soluble solids: 5 ± 0,01 ° Brix, Acidity: 0,36 ± 0,01%, Density: 1,02 ± 0,01g / ml, Viscosity: 13,55 ± 0,15 cP, Color Index: -14,03 ± 1,65 and FOS (1-Kestose: 0,06% and Nystose: 0,13%).

Published: July 2020

Pembuatan sampan berbahan ember cat bekas diharapkan dapat menjadi alternatif pengganti kayu yang semakin sulit diperoleh dan pengganti bahan serat fiber yang tidak murah. Namun sampan ini memiliki kekurangan, yakni stabilitasnya yang rendah. Bobotnya yang ringan membuat sampan mudah oleng meskipun hanya beroperasi diperairan yang relatif tenang. Oleh karenanya instalasi sirip peredam oleng (bilge keel) diharapkan dapat meningkatkan stablitas sampan ini. Tujuan penelitian ini adalah untuk mendapatkan nilai stabililitas sampan dengan instalasi bilge keel pada sudut yang berbeda dalam rangka mendapatkan stabilitas sampan yang baik. Ukuran sampan yang dijadikan obyek dalam penelitian ini adalah panjang (LOA) 3,15 m; lebar (B) 0,64 m; dalam (D) 0,30 m. Metode simulasi numerik untuk mendapatkan nilai stabilitas serta beberapa parameter seakeeping (pitching, roling dan heaving) digunakan dalam penelitian ini dengan bantuan perangkat lunak yang sesuai. Hasil analisis menunjukkan bahwa terdapat perbedaan stabilitas yang ditunjukkan oleh nilai lengan GZ (righting arm) pada sampan yang dipasangi bilge keel dengan sudut 30 dan 60 derajat sebesar 0,002 m. Bilge keel dengan sudut 30 derajat memberikan nilai stabilitas yang lebih besar dibandingkan dengan sudut 60 derajat.

Lomek and biang fish are types of fish commonly used as raw materials for making salted fish in Dumai. Industrial activity in Dumai can influence on heavy metal content in dried salted fish. In addition, the requirements for the quality of salted fish are salt concentration and Salmonella test. The aim of this study were to determine heavy metal (Pb and Cd), salt concentration, and Salmonella test in dried salted fish. The study was carried out the preparation of raw materials and the manufacture of salted fish using dry salting method with a salt concentration of 5%, 10% and 15% for lomek and biang fish. The second was the analysis of heavy metal, salt concentration, and Salmonella test. The addition of 10% salt concentration to Lomek fish was the highest result for Pb (1,48± 0,01 ppm), while all samples were not identified for Cd levels. The highest salt concentration was L3 that was 22,45%, while for Salmonella test results all samples were negative. Based on the results, it was concluded that Pb contamination passed the safe limit, while Cd was not detected. The difference in salt addition gave an effect on the salt concentration for dried salted lomek and biang. Salmonella were not found in all salted fish samples.Keywords : Food safety, pathogen, product quality, salted method
