BISNIS SYARIAH; TRANSAKSI TIDAK TUNAI MENURUT PANDANGAN WAHBAH AL-ZUHAILY DALAM TAFSIR AL-MUNIR
Authors: Adiyes Putra Popi , Z. Hrp Ade Khadijatul , Tarigan Azhari Akmal , Nasution Yenni Samri Juliati
Published: May 2022

Bisnis adalah upaya untuk mendapatkan keuntungan lewat jalur perdagangan. Perdagangan atau jual beli dilakukan secara tunai maupun secara tidak tunai. Terkait dengan ketentuan dalam transaksi tidak tunai, Allah SWT menyebutkannya dalam Al-Qur’an pada Surat Al-Baqarah ayat 282-283 secara jelas. Dalam ayat ini diterangkan pencatatan transaksi tidak tunai ini ditujukan untuk melindungi hak-hak orang yang bertransaksi agar tidak terjadi kehilangan barang/uang sebagai akibat dari perselisihan. Pencatatan ini juga dikuatkan oleh adanya saksi dari orang yang berprilaku adil, benar dan tidak berpihak kepada salah satu yang bertransaksi, sehingga transaksi secara tidak tunai akan terhindar dari keraguan dan penyelewengan. Transaksi secara tidak tunai dewasa ini dilaksanakan dalam bentuk akad murabahah. Akad murabahah yang dipraktekan lembaga keuangan syariah memunculkan berbagai macam praktek-praktek yang menyimpang dari kaedah syariah seperti yang dijelaskan dalam Surat Al-Baqarah ayat 282-283 ini. Terkait dengan penjelasan dalam bentuk tafsir ayat tentang transaksi secara tidak tunai ini, Tafsir Al-Munir karya Imam Az-Zuhaili menjelaskan secara rinci ketentuan-ketentuan dalam transaksi tidak tunai tersebut. Karena kajian dalam penelitian berdasarkan pada telaah atas bacaan-bacaan terutama bacaan dalam Tafsir Al-Munir, maka penelitian ini tergolong kepada penelitian kepustakaan dengan metode kualitatif.
Law and Violence
Authors: Guerrero Alexander
Published: May 2022

The law marks a significant difference between violent and non-violent criminal actions. Violent crimes are typically met with more severe punishments and consequences than non-violent crimes. Even in discussions of criminal justice reform, the refrain remains: violent crime is different; those convicted of violent crimes are different; and it is appropriate to respond to violent crime differently. This article argues that the violent/non-violent distinction cannot bear the normative weight placed on it and that we should jettison violence and move to thinking about objectionable harm caused and risked. There are moral constraints on punishment from considerations of proportionality and equality, these are connected to wrongful harm and facts about agent culpability, and there is no consistent relationship between violence and wrongful harm nor between violence and culpability. The article concludes by offering an error-theory concerning our commitment to treating violent crime differently and suggests that morally better categorizations are available.
Platelet-Rich Fibrin Versus Connective Tissue Graft Using Vestibular Incision Subperiosteal Tunnel Access (VISTA) Technique in Multiple Gingival Recessions: Randomized Controlled Trial
Authors: Serry Yasmin , Hegab Marwa , Keraa Khaled , El Barbary Ahmed
Published: May 2022

Background: One of the most common esthetic concerns in dentistry is gingival recession (GR), and despite the various treatment strategies for root coverage, multiple recessions still present a great challenge, especially Miller Class III/RT2. Thus, this study aimed to compare the effect of platelet-rich fibrin (PRF) versus connective tissue graft (CTG) using vestibular incision subperiosteal tunnel access (VISTA) in patients with Miller class III/RT2 multiple recessions for root coverage. Methods: Twenty-eight patients with multiple Class III/RT2 gingival recessions were randomly allocated to two equal groups – group 1 (VISTA+PRF) and group 2 (VISTA+CTG). Recession depth (RD) and width (RW), probing depth (PD), clinical attachment level (CAL), gingival thickness, keratinized tissue width, and root coverage esthetic score (RES) were measured at 0, 3, and 6 months. Statistical analysis was performed using repeated measures analysis of variance (ANOVA). Bonferroni’s post-hoc test was used for pair-wise comparisons when ANOVA was significant. For non-parametric data, the Mann-Whitney U test was used to compare between the two groups. Results: Within each group, a significant difference from baseline to six months was found. However, between groups, the results for the VISTA+CTG group significantly surpassed the VISTA+PRF group in most clinical outcomes; gingival recession depth (0.5 [0.25-1.75] and 1.33 [0.75-2], respectively), and width (1 [0.38-3.75] and 2.33 [1.33-3], respectively), gingival thickness at three and six months (2.62±0.36 and 2.63±0.36, respectively) and (1.85±0.2 and 1.87±0.18, respectively), and keratinized tissue width (3.98±0.72 and 3.33±0.56, respectively). However, CAL and PD showed a statistically insignificant difference when comparing both groups. Conclusion: The use of CTG is superior to PRF in root coverage of Miller Class III/RT2 when the VISTA technique is used. Connective tissue grafts can be considered the gold standard for root coverage.
A qualitative exploration of the views of paramedics regarding the identification of cardiovascular risk factors in the pre-hospital environment
Authors: Taylor Josie , McClelland Graham
Published: May 2022

Background: Cardiovascular disease remains the most prominent cause of death in England. Healthcare professionals have been encouraged to identify cardiovascular risk factors (CVRFs). The aim of this study was to explore how paramedics contribute to the identification of CVRFs
in the pre-hospital setting, through their role, behaviours and practice.Methods: The study took place within the North East Ambulance Service NHS Foundation Trust supported by a National Institute for Health Research clinical research internship. A qualitative approach was used,
and a single focus group was conducted. The study recruited participants through advertising for volunteers and purposive sampling. The themes that arose from the focus group allowed the initial exploration of the views of paramedics in relation to role, behaviour and practice in identifying
CVRFs.Results: A single focus group with five paramedics was conducted in June 2021. Two central themes emerged: education/health promotion and fear/anxiety. Participants agreed that their role in this area centred around patient education. Participants’ behaviours and practice
were adversely affected through fear of complaints, fear of hypocrisy and feeling a lack of support from the ambulance service. Participants felt that further training and subsequent indemnity from complaints would improve the likelihood of more direct patient education. Support from the ambulance
service to improve employees’ own health and well-being was also a key topic of discussion.Conclusion: The study explored the views of a small sample of paramedics on this topic. Patient education was felt to be part of a paramedic’s role; however, barriers were identified
that prevent paramedics from carrying out this role. Further research is needed to explore these barriers further.
Not so FAST: pre-hospital posterior circulation stroke
Authors: Devlin Shane
Published: May 2022

Introduction: Posterior circulation strokes account for 20% of ischaemic strokes, but may present differently to their anterior circulation counterparts. Patients may not exhibit unilateral facial weakness, speech disturbances and unilateral limb weakness, but instead present
with more vague symptoms of sudden headache, dizziness, loss of balance and visual problems. This case describes a patient displaying signs and symptoms of a posterior stroke, but who eluded the FAST (face, arm, speech, time) test.Case presentation: An ambulance was called for a
60-year-old man who had a sudden onset of generalised weakness, diaphoresis and one episode of emesis at home in rural Ireland. He had a history of hypertension, hypercholesterolaemia, angina and a coronary stent placed 4 months previously. Cardiac, respiratory, abdominal, urinary and gastrointestinal
exams were unremarkable. Vital signs and 12-lead electrocardiogram were normal. He was FAST negative on exam. Due to persistent dizziness, further neurological exams were carried out, showing a left visual field neglect, new nystagmus, left-sided dysmetria on finger-to-nose and heel-to-shin
tests and he was unable to walk unassisted upon standing. A posterior circulation stroke was suspected, and the nearest stroke unit was pre-alerted en route. A rapid assessment and computed tomography took place at hospital, with timely thrombolysis with tissue plasminogen activator. The patient
subsequently had a full neurological recovery.Conclusion: This case describes a patient displaying signs and symptoms of a posterior circulation stroke albeit being FAST negative on exam. There is potential here to improve our recognition of posterior stroke in the pre-hospital
field by including additional neurological exams to the FAST test. Use of ‘BEFAST’ (balance, eyes, face, arm, speech, time), the finger-to-nose test, and the ‘5 Ds’ and ‘DANISH’ mnemonics may help increase recognition of these subtle presentations.
Assuring safe artificial intelligence in critical ambulance service response: study protocol
Authors: Sujan Mark , Thimbleby Harold , Habli Ibrahim , Cleve Andreas , Maaløe Lars , Rees Nigel
Published: May 2022

Introduction:Early recognition of out-of-hospital cardiac arrest (OHCA) by ambulance service call centre operators is important so that cardiopulmonary resuscitation can be delivered immediately, but around 25% of OHCAs are not picked up by call centre operators. An artificial intelligence (AI) system has been developed to support call centre operators in the detection of OHCA. The study aims to (1) explore ambulance service stakeholder perceptions on the safety of OHCA AI decision support in call centres, and (2) develop a clinical safety case for the OHCA AI decision-support system.Methods and analysis:The study will be undertaken within the Welsh Ambulance Service. The study is part research and part service evaluation. The research utilises a qualitative study design based on thematic analysis of interview data. The service evaluation consists of the development of a clinical safety case based on document analysis, analysis of the AI model and its development process and informal interviews with the technology developer.Conclusions:AI presents many opportunities for ambulance services, but safety assurance requirements need to be understood. The ASSIST project will continue to explore and build the body of knowledge in this area.
‘Very hit and miss’: an interpretive phenomenological analysis of ambulance service care for young people experiencing mental health crisis
Authors: Gee Brioney , Nicholls Helen , Rivett Sam , Clarke Tim , Wilson Jon , Prothero Larissa
Published: May 2022

Introduction: The ambulance service provides vital front line mental healthcare for young people in crisis, but there is a lack of evidence to guide best practice in this area. The lived experiences of service users can offer important insights to guide service development, therefore
we carried out a qualitative evaluation of care provided by the ambulance service to young people experiencing a mental health-related emergency.Methods: Ten participants aged 16‐25 years who had used the ambulance service due to a mental health crisis within the past 2 years
were interviewed about their experiences and view of the care they received. Interviews were transcribed verbatim and interpretative phenomenological analysis used to explore participants’ individual narratives and identify recurrent themes.Results: A theme of inconsistent
quality of care was evident in all participants’ accounts. Contributing to this superordinate theme were six recurrent themes: positive qualities of individual ambulance clinicians, ambivalence about seeking care, the importance of retaining agency, need for mental health training for
ambulance clinicians, need for inter-service collaboration and favourable comparison of the ambulance service to other services.Conclusions: We identified some examples of good practice, including person-centred care, respect for patient autonomy and attending to physical health
needs. However, our findings suggest the quality of ambulance service mental healthcare is not yet sufficiently consistent. In the absence of mandatory high-quality mental health training and evidence-based protocols, the quality of care appears largely dependent on the qualities and experience
of individual ambulance clinicians.
Documentation of atrial fibrillation among non-conveyed ambulance patients: a new primary prevention opportunity?
Authors: Heppenstall Emily , McClelland Graham , Price Chris , Wilkinson Chris
Published: May 2022

Introduction: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and is a significant risk factor for stroke. Prescription of oral anticoagulant (OAC) medication reduces the risk of AF-related stroke by 64% ‐ yet over 400,000 people in England have
undiagnosed (and therefore untreated) AF.Emergency medical services (EMS) encounter a wide range of patients, some of whom may not engage with other healthcare services. AF may be detected by EMS in connection with the cause of the call, or as an incidental finding. While EMS are not traditionally
utilised for public health screening, they may offer an opportunity to identify patients with undiagnosed or untreated AF and refer onward.This study aimed to explore what proportion of patients seen by EMS who were not transported to hospital had AF and to estimate how many would potentially
benefit from OAC.Methods: A retrospective service evaluation was conducted using routinely collected data from a large UK regional ambulance service. The sample included adults attended by EMS on the 15th of each month in 2019, who were not transported to hospital and where an electrocardiogram
was recorded. Of those with AF, we calculated the proportion in whom this was possibly new and report whether OAC was prescribed.Results: There were 859 patients who met the inclusion criteria, of whom 91 (11%) had AF documented. Of the 91 patients with AF, 23 (25%) had no documented
history of AF or OAC prescription, so were potentially new diagnoses of AF, who would benefit from consideration of OAC therapy.Conclusion: The EMS assessment offers an opportunity for AF to be identified in patients who were not transported to hospital. EMS may have a role in primary
prevention of harm, including stroke, by identifying and referring patients with AF for consideration of OAC.
The effect of a specialist paramedic primary care rotation on appropriate non-conveyance decisions (SPRAINED) study: a controlled interrupted time series analysis
Authors: Pilbery Richard , Young Tracey , Hodge Andrew
Published: May 2022

Introduction:NHS ambulance service non-conveyance rates in the United Kingdom are around 30%, despite an increase in non-emergency cases and a national policy of integrating urgent and emergency care to provide patients with the ‘right care, in the right place, at the right time’. Emergency department overcrowding is a significant issue for patients, resulting in poorer quality of care, increased healthcare costs and potentially, increased mortality. It also contributes to increased ambulance turnaround times. Yorkshire Ambulance Service NHS Trust (YAS) introduced a specialist paramedic (SP) to improve the management of lower acuity cases, but non-conveyance rates in this group have not been as high as expected.In 2018, Health Education England funded a pilot scheme to rotate paramedics into a range of healthcare settings and in YAS, 10 SPs undertook a 10-week placement in a GP practice. This study aimed to evaluate whether a primary care placement appropriately increased the level and trend of non-conveyance decisions made by SPs following a 10-week GP placement, in a cost-effective manner.Methods:We conducted a controlled interrupted time series analysis using data from incidents between 1 June 2017 and 31 December 2019, to study appropriate non-conveyance rates before and after a GP placement. A costing analysis, examining the average cost per appropriate non-conveyance achieved for patients receiving care from intervention group SPs pre- and post-placement, was also conducted.Results:A total of 7349 incidents attended by intervention group SPs were eligible for inclusion. Following removal of cases with missing data, 5537 (75.3%) cases remained. Post-placement, the intervention group demonstrated an increase in appropriate non-conveyance rate of 35.0% (95% CI 23.8%‐46.2%), and a reduction in the trend of appropriate non-conveyance of -1.2% (95% CI -2.8%‐0.5%), relative to the control group.Post-placement, the cost per appropriate non-conveyance for intervention group SPs was a mean of £509.41 (95% bootstrapped CI £454.92‐£564.26) versus £1257.81 (95% bootstrapped CI £1233.42‐£1283.95) for the same group in the pre-placement phase.Conclusion:In this single UK NHS ambulance service study, we found a clinically important and statistically significant increase in appropriate non-conveyance rates by SPs who had completed a 10-week GP placement. This improvement persisted for the 12-month period following the placement and demonstrated cost savings compared to usual care.
Strategic Environmental Policies in the Presence of Differentiated Goods
Authors: Espinosa Ramírez Rafael Salvador , Sandoval Salvador
Published: May 2022

We develop a theoretical model of partial equilibrium where firms, located in a country, compete and produce differentiated goods in a duopolistic market. Emission of pollution is related to production, and firms produce their output using different levels of polluting technology. To control pollution emission, the government applies discriminatory pollution quotas considering the benefits for firms, consumers, and environmental damage. The results show that if the disutility to be polluted is very high, the government imposes a zero-emission quota on the companies. But, if such disutility is not significantly high, it allows a certain amount of emissions, imposing different quotas on firms depending on the levels of technology they use to control their emissions. The proposed model stresses the importance of the rational establishment of strategic environmental policies, which benefit all economic agents in the market, firms, consumers, and the environment.
 
Resumen
Desarrollamos un modelo teórico de equilibrio parcial donde las empresas, ubicadas en un país, compiten y producen bienes diferenciados en un mercado duopolístico. La emisión de contaminación está relacionada con la producción, y las empresas producen utilizando diferentes niveles de tecnología contaminante. Para controlar la emisión de contaminación, el gobierno aplica cuotas de contaminación discriminatorias teniendo en cuenta el beneficio para las empresas, los consumidores y el daño ambiental. Los resultados muestran que si la desutilidad a contaminar es muy alta, el gobierno impone una cuota de cero emisiones a las empresas. Pero, si dicha desutilidad no es significativamente alta, permite una cierta cantidad de emisiones, imponiendo diferentes cuotas a las empresas dependiendo de los niveles de tecnología que utilizan para controlar sus emisiones. El modelo propuesto subraya la importancia del establecimiento racional de políticas ambientales estratégicas, que actúen en beneficio de todos los agentes económicos en el mercado, las empresas, los consumidores y el medio ambiente.
Student Engagement in Concept Mapping
Authors: Onabadejo Dr. Juliet , Camacho Richard
Published: May 2022

Student engagement has been an important discourse in higher education, and researchers have determined that engagement in educational activities is vital for student retention. Retaining students in learning is crucial in a stressful healthcare environment, hence the need to identify the associated engagement factors. Concept mapping offers students a realistic venue for critical thinking, clinical reasoning, and engagement in educational activities. Building on the results obtained from a basic qualitative study where, interviews and journals were analyzed, we examined the theoretical basis for students’ engagement during concept mapping in a flipped clinical learning. Accordingly, this article discusses the factors that influenced engagement while concept mapping within a stressful healthcare clinical learning environment and explains how the process of mapping patient care improved students’ engagement in learning. The impacts of concept mapping process went beyond participation to self-direction, higher-level thinking, and greater impact on clinical decision making for the student participants.
Signature Pedagogies -- A Cautionary Tale
Authors: Kelly Theodore
Published: May 2022

The idea that each discipline in higher education has its own unique "signature pedagogy" has gained popularity since Lee Shulman first proposed the idea in 2005. But can the focus on signature pedagogies in SOTL work be a problem as well as a benefit? This essay explores both the history of signature pedagogies and the possible downside of the use of this concept to frame SOTL research and teaching informed by SOTL.
Who's at the Research Table?

Published: May 2022

In this reflection, a group of undergraduate research assistants and student changemakers use a podcast to explore which students are at the research table, and what barriers are keeping many others outside of it. This student-authored paper and SoTL-inspired auditory experience dives into multiple demographic topics such as gender, race, and socio-economic status in relation to student-faculty partnerships in the research realm. Both listeners and readers are encouraged to reflect on the recruitment process they use in finding their student partners, and how they can better serve priority populations and implement diversity and inclusion in their practice.
Considerations for Seeking Equity and Justice through Pedagogical Partnership
Authors: De Bie Alise , Krishna Prasad Srikripa , Nguyen Elaina , Marquis Elizabeth
Published: May 2022

Student-faculty pedagogical partnership has recently been understood to have the potential to contribute to equity and justice in postsecondary education. Nevertheless, important equity-related concerns about partnership have also been raised. In a presentation at a previous Symposium on Scholarship of Teaching and Learning, one of the co-authors of this article proposed a series of "tentative principles" for working toward equity in and through student-faculty partnership, which synthesized and foregrounded some of these possibilities and critiques. In this article, we share these "tentative principles," as well as a series of critical responses to them, offered by the three co-authors. In so doing, we aim to offer an expanded set of significant considerations for those interested in student-faculty partnership and equity, and to invite and encourage further discussion and critique rather than reify singular principles.

In this invited article, we reflect on how SoTL came to be, at least within one institution, Mount Royal University (MRU). We caught up with Dr. Jim Zimmer, Associate Professor in General Education and past- Associate Vice-President of Teaching and Learning to discuss the early days of SoTL at MRU, and his perspectives and role in laying the foundations for SoTL at MRU. We also discuss how Jim has seen SoTL evolve over the last 10-15 years and some of the key catalysts that, in his view, formalized SoTL as an integral part of MRU.

Analysis of output characteristics of ion sensitive field effect transistor based biosensor for measurement of pH in biochemical solutions
Authors: Babatunde S. Emmanuel
Published: May 2022

The need for improved system’s response time, sensitivity, selectivity and miniaturization has continued to form the premise for focusing research attention on innovative design and development of biochemical sensors. Ion sensitive field effect transistor (ISFET) can be used to innovatively drive biochemical sensors for the measurement of concentration of ions and molecules in solutions. This simulation study focuses on the determination of output characteristics of ISFET pH sensor as applied in the measurement of concentration of hydrogen potential (pH) which is a function of the proton concentration in an analyte solution. The pH of a target analyte interacts with the ion sensitive membrane of ISFET to produce charges which in turn changes the potential of the working electrode of the sensor. The output characteristic of interest is the gate voltage of ISFET which is a function of pH concentration of analyte under study. The relationship between the sensor’s input pH concentration and its output gate voltage describes the sensitivity of the device. From the results obtained from the study, as the input pH concentration was increased from 5 to 11, the output gate voltage ISFET pH sensor increased from 2.65 V to 2.9 V.

Published: May 2022

The study examined the determinants of compliance to safety and health measures in construction sites in Kampala Central Division, Uganda. Questionnaires containing information relating to safety and health measures at the sites were administered randomly to the construction workers selected from four (4) selected building sites across the division. The results revealed that there was a 95% level of compliance to safety and health measures which is considered an unacceptable standard and requires attention in the short term according to the scale developed by MBSAT, among the building construction workers in the division. It was also established that there were no personal determinants that affected compliance to safety and health measures within the division as all of them were found to be statistically insignificant. This indicated that none of the personal determinants is a significant predictor of compliance (at 5% level of significance). The results further revealed that there was a significant association between three organizational determinants of compliance: adequacy of legislation, availability of personal protective equipment (PPE) and availability of standard operating procedures (SOPs) or policy. This proved that there is an association between personal and organizational determinants of compliance to occupational safety in construction sites in Kampala Central Division (at 5% level of significance). However in practice this means there is no one single factor which can determine compliance but a combination of factors of which the organizational factors are more significant in compliance than personal determinants.

Published: May 2022

This study was undertaken to assess the effect of total excusive breast feeding on the prevalence of malaria among children, 0-2 years of age. A simple random sampling method was used to select 176 nursing mothers, having children aged 0-2 years during consultation hours at the pediatric outpatient ward of the Federal Medical Center, Owerri, Nigeria. A well-structured interviewer administered questionnaire was used to source information from the nursing mothers that provided answers to the questions on socio demographic characteristics and breast feeding practices. Blood samples also were collected from the concerned children, stained with Giemsa and Leishman for both thick and thin film preparations respectively, and examined under the oil immersion microscopy for malaria parasites. The results showed that 100% of the mothers had good knowledge of breast feeding, but their practice of total exclusive breast feeding was low (22.7%). Out of 40 exclusively breast-fed children examined in the study, only 4(10.0%) were infected with malaria, while out of the 136 non-exclusively breast-fed children, 50(36.8%) had malaria. The prevalence of malaria was also lowest (6.7%) among the exclusively breast-fed children in the age group 0-6 months. Total exclusive breast feeding practice should be sustained and recommended to all nursing mothers in order to gain from its numerous and indispensable benefits including reduction in the prevalence of malaria among children.
MARITIME CRYPTOLOGY
Authors: Alamsyah Intan Muchtadi
Published: May 2022

Maritime has special needs for information security, including the protection of classified information. As written in â€œCryptographyâ€™s Role in Securing the Information Societyâ€: â€˜Cryptography provides important capabilities that can help deal with the vulnerabilities of electronic information. Cryptography can help to assure the integrity of data, to authenticate the identity of specific parties, to prevent individuals from plausibly denying that they have signed something, and to preserve the confidentiality of information that may have improperly come into the possession of unauthorized parties [Dam and Lin, 1996].

Elliptic Curve Cryptography (ECC) was first introduced by Neal Koblitz and Victor Miller ([Koblitz1987],[Miller1985]). They independently introduced the elliptic curve to design a public-key cryptography. Compared to other cryptography method, it has several advantages: its arithmetic operations are spesific and can not be predicted, it offers smaller key length for the same security level compared to other method and its operations have many layers and combinations. ECC relies on the security level of the discrete logarithm problem called Elliptic Curve Discrete Logarithm Problem (ECDLP) [Hankerson et al, 2004].

The deposition of heavy metals in Ambon Bay was investigated by using sponge species (Callispongia sp.) as bioindicator. Two different sampling schemes are discussed in this paper: a random sampling scheme with 8 sampling sites distributed over the whole territory of Ambon Bay. Unwashed, dried samples were totally the concentrations of metal elements were determined by inductively coupled plasma atomic emission spectroscopy (ICP-AES). Heavy metal Cd. The median concentrations and statistical parameters of elements were discussed by comparing two sampling schemes. The results of both sampling schemes are compared with the results of other the location of the net. Different levels of the contamination valuated by the respective contamination factor (CF) of each element are obtained for both sampling schemes, while the local contamination  identified like cadmium metallurgy and cement industry, oil refinery, mining industry, and transport have been the same for both sampling schemes. In addition, the natural sources, from the accumulation of these metals in sponge caused by metal-enriched soil, associated with activity in the land were pointed as another possibility of local factors.

Has made an alcohol concentration detector based on microcontroller that can detect alcohol concentration in liquor is accurate, fast, stable and has a high sensitivity. In this research, use traditional liquor of Moluccas â€œSopiâ€, and liquors on the market. An alcohol concentration detector was built based on microcontroller ATmega16 which can receive and process data from the sensor MQ-3 in a form that can be converted into the form of an electrical signal and the output is displayed on the LCD. Calibration of the sensor MQ-3 shows that the greater the value of resistance sensor, the smaller the value of an alcohol concentration. The correlation of resistance sensor to alcohol concentration is plotted in a graph of linearity with R2 = 0,9982. The results of liquor on the market and Sopi (premium quality) had alcohol concentration ranging between 3 â€“ 5% per mL, while an alcohol concentration of Sopi (regular quality) is below 3% per mL.

At present, fossil fuels are playing the major role to meet the energy requirements of the world. The large consumption of fossil fuels creates so many environmental problems, such as green-house gases have motivated the search for alternative, renewable fuel options. Biomass is one of the few resources that have the potential to meet the challenges of sustainable and green energy systems. Current biomass resources comprise primarily industrial waste materials such as sawdust or pulp process wastes, hog fuel, forest residues, clean wood waste from landfills, and agricultural prunings and residues from plants such as lignocellulosic materials. There are already a considerable range of chemical building blocks derived from renewable resources. Among them, 5-hydroxymethylfurfural (HMF) is a versatile platform chemical for the synthesis of a wide range of industrially important materials, including biofuels.

The eyes are one of the vital organs owned by humans. One of the common eye diseases is cataracts. This disease is characterized by clouding of the lens of the eye and can interfere with vision. Worst case, sufferers can experience blindness. Cataract maturity can be divided into four categories, namely incipient, immature, mature, and hypermature. Cataracts can be removed through surgery when the cataract is in the mature or hypermature phase. Cataract examination is usually done using a slit lamp. The lack of hospitals that have this equipment can cause delays in the healing process for cataract sufferers. This study created an image processing algorithm for the maturity classification process of cataracts using the Convolutional Neural Network method with LeNet network architecture. The algorithm that has been built is capable of classifying the maturity of cataracts with an accuracy rate of 93.33%

One of the tofu-producing companies in Kupang City is Bintang Oesapa. With the Covid-19 pandemic,the factory needs to reconsider the amount of production by taking into account the unpredictability ofdemand and resources to minimize losses due to excessive accumulation or shortages of supplies. Indetermining the amount of production, Mamdani’s Fuzzy Inference System (FIS) can be used, whichis a method for the analysis of an uncertain system. This method has three stages in the process ofdecision making, namely fuzzification, inferencing and defuzzification. In the defuzzification stage,the FIS Mamdani has five methods, namely Centroid, Bisector, Mean of Maximum (MOM), Smallestof Maximum (SOM), and Largest of Maximum (LOM). This study discusses an application of FISMamdani with five defuzzification methods for determining daily tofu production. The purpose of thisstudy is to offer a solution by first comparing the five defuzzification methods in assessing the amount oftofu production at the Bintang Oesapa factory and then determining that which is most appropriate. Theinput variables used in this research are the amount of demand and the amount of available stock, whilethe amount of production is our variable of interest. The results showed that the best defuzzificationmethod was the MOM method with an accuracy level of 94.73% and a small error value, 5.27%. TheMOM defuzzification is expected to aid decision makers in determining the best amount of productionduring the pandemic.
