Speaking anxiety during English oral presentations
Authors: Alharbi Ayed T.
Published: October 2022

Students at the tertiary level must be placed in an interactive learning setting since traditional lectures are no longer the most effective method of getting students involved in active learning. One of the criteria for passing the course in the department of English and Translation at Qassim University is the performance in the oral presentation simulation. Since this performance of a presentation is not just dependent on the cognitive domain but also the affective dimension, and speaking anxiety can be detrimental to students’ performance affecting their learning motivation in the long run and grades in the short term. This study, therefore, examines the level of anxiety, signs of anxiety and factors that lead to oral anxiety among Saudi EFL students. Fifty students from the department of English and Translation at Qassim University’s second semester comprised the study sample. Direct observation, in-depth interviews, and surveys were used to collect data from the participants. Results show that students experience moderate levels of anxiety related to language  (M= 3.51, SD= 0.54).

İnsanın olduğu her yerde var olan ve engel olunmadığı sürece varlığını artırarak devam ettiren şiddet, günümüzde en büyük toplumsal sorunlardan biridir. Kişinin kendisine ya da karşısındakilere (canlı, cansız her tür varlık olabilir) üstünlük sağlamak amacıyla fiziksel ve/veya duygusal biçimde uyguladığı baskıyı, zorlamayı ifade eden, gerek bireysel, gerek toplumsal açıdan genel olarak kötüyü çağrıştıran bir ifadedir. Bu bakışla, güzelle örtüşen unsurları şiddetle bağdaştırabilmek daha zordur. Bu yönden çoğu kişi tarafından güzel algısıyla bütünleştirilen sanatın şiddetle anılması çok da alışıldık bir yaklaşım değildir. Özünde güzeli barındırması beklenen sanatla uğraşan kişilerin, şiddete ilişkin tutumlarının nasıl olduğu sorusundan hareketle başlayan çalışma, müzik eğitimi alan ve bu alanda mesleğini sürdüren bireylerle sınırlandırılmıştır. Türkiye’de farklı bölgelerde çalışan 100 müzik öğretmeninin şiddet tutumlarını belirlemek amacıyla, Adıbelli, Saçan ve Türkoğlu tarafından geliştirilen Şiddet Tutum Ölçeği kullanılmıştır. Şiddet tutumuna farklı değişkenlerin etkisini saptamak amacıyla kişisel bilgi formundan yararlanılmıştır. Verilerin analizi için SPSS 22 istatistik programı kullanılmıştır. Cinsiyetin, yaşın, mezun olunan lise türünün, müzik öğretmenlerinin okudukları kitap, izledikleri film, dinledikleri müzik türlerinin, şiddet tutumları üzerindeki etkilerini belirlemeye yönelik sorular neticesinde, dinlenilen müzik türü ile şiddet tutum düzeyi arasında anlamlı sonuçlar elde edilmiştir.

The data of comparative studies of the development of plastic flow in pure aluminum and iron-based austenitic alloy (Fe-Cr-Ni) are presented. Deformation patterns were studied during tests in the temperature range 143-420 K. It was found that the effect of temperature is different for these two cases. When a stationary dissipative structure appears at the stage of parabolic strain hardening, the effect of temperature is determined by the change in the length of the localized plasticity autowave. At the stage of linear strain hardening, when a phase autowave of localized plasticity is formed, the effect is associated with an exponential increase in its rate with temperature.

The study of the supercapacitor electrodes based on silicon-carbon films obtained by electrochemical deposition from solutions with different ratios of methanol/hexamethyldisilane and addition of manganese and nickel salts was carried out using cyclic voltammetry, electrochemical impedance spectroscopy and impedance hodograph simulation by equivalent circuits method. The predominance of mesopores in the electrode samples was confirmed by the functional density method. According to a scanning electron microscopy study, the surface morphology of the silicon-carbon films is highly developed due to the presence of three-dimensional agglomerates and "foliated" structures. The best retention of specific capacity after 450 charge/discharge cycles is observed for electrode samples containing manganese and nickel. Simulation of equivalent circuits showed that all types of electrodes have hierarchical pore structure, after 450 charge/discharge cycles an increase in pore storage resistance and a decrease in transport pore resistance due to the activation of deeper pore levels is observed. The applicability of Peukert's law for this type of electrodes for prediction of electrode discharge time is shown.

The optical and electrical properties of bismuth ferrite thin films obtained by high-frequency magnetron sputtering in an atmosphere of argon and oxygen (80% + 20%) has been studied. Investigations of the optical properties have shown that for polycrystalline bismuth ferrite films the optical band gap is ~3 eV, which is in the range of given in the literature values. The dependences of the specific electrical conductivity on the magnitude of the electric field has been studied for the synthesized films. It has been established that the electrical conductivity does not depend on the electric field strength up to the value of E = 2.1106 V/m. The experimental results are discussed in terms of the model of charge carrier injection from aluminum electrode into the conduction band of bismuth ferrite.

Using X-ray diffraction, there were determined the residual stresses on the surface of the AISI 310S stainless steel carrier tape used in manufacture of the second generation high temperature superconducting (2G HTS) wires at the National Research Center “Kurchatov Institute”, from delivery to deposition of the main buffer layer YSZ between the tape and the superconducting layer, and the residual stress in the buffer layer YSZ itself. The compressive stress of –0.8 GPa induced by rolling was found on the surface of the tape as-delivered. During processing, it varies from –0.5 to –1.1 GPa. At each stage, its depth distribution was found down to 10 μm, and the residual stresses caused by processing were determined. The residual stress in the YSZ layer deposited using the ABAD technology is compressive and amounts to –3.29 GPa. The layer has a defective single-crystal structure in type to radiation swelling with the unstressed lattice period of 5.1820 Å, 0.9% larger than in ordinary crystal. The results obtained are in agreement with the data of the earlier neutron diffraction study of residual stresses inside the carrier tape.
Use of Artificial Intelligence in the Search for New Information Through Routine Laboratory Tests: Systematic Review
Authors: Cardozo Glauco , Tirloni Salvador Francisco , Pereira Moro Antônio Renato , Marques Jefferson Luiz Brum
Published: October 2022

Background

In recent decades, the use of artificial intelligence has been widely explored in health care. Similarly, the amount of data generated in the most varied medical processes has practically doubled every year, requiring new methods of analysis and treatment of these data. Mainly aimed at aiding in the diagnosis and prevention of diseases, this precision medicine has shown great potential in different medical disciplines. Laboratory tests, for example, almost always present their results separately as individual values. However, physicians need to analyze a set of results to propose a supposed diagnosis, which leads us to think that sets of laboratory tests may contain more information than those presented separately for each result. In this way, the processes of medical laboratories can be strongly affected by these techniques.

Objective

In this sense, we sought to identify scientific research that used laboratory tests and machine learning techniques to predict hidden information and diagnose diseases.

Methods

The methodology adopted used the population, intervention, comparison, and outcomes principle, searching the main engineering and health sciences databases. The search terms were defined based on the list of terms used in the Medical Subject Heading database. Data from this study were presented descriptively and followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses; 2020) statement flow diagram and the National Institutes of Health tool for quality assessment of articles. During the analysis, the inclusion and exclusion criteria were independently applied by 2 authors, with a third author being consulted in cases of disagreement.

Results

Following the defined requirements, 40 studies presenting good quality in the analysis process were selected and evaluated. We found that, in recent years, there has been a significant increase in the number of works that have used this methodology, mainly because of COVID-19. In general, the studies used machine learning classification models to predict new information, and the most used parameters were data from routine laboratory tests such as the complete blood count.

Conclusions

Finally, we conclude that laboratory tests, together with machine learning techniques, can predict new tests, thus helping the search for new diagnoses. This process has proved to be advantageous and innovative for medical laboratories. It is making it possible to discover hidden information and propose additional tests, reducing the number of false negatives and helping in the early discovery of unknown diseases.

Authors: Berentsen Birgitte , Hillestad Eline Margrete Randulff , Steinsvik Elisabeth Kjelsvik , Hausken Trygve , Hatlebakk Jan Gunnar
Published: October 2022

BACKGROUND

Patient education can influence patient behavior that subsequently may lead to changes in attitudes and skills necessary for maintenance or improvement in management of symptom severity and quality of life.

OBJECTIVE

In this randomized study, we have investigated the effects of a digital eHealth program on the domains of symptom severity, quality of life, anxiety and depression, and a measure of general client satisfaction, compared to a physical patient school, in a cohort of 256 patients with irritable bowel syndrome (IBS).

METHODS

All patients were enrolled after referral to Section of Gastroenterology at Haukeland University Hospital (HUH). Data were collected at enrolment and after three months, between 2017 and 2019.

RESULTS

On group level, patients attending the eHealth program reported a significant reduction in IBS symptom severity 3 months after treatment (n = 71), compared to patients attending the IBS-school (n = 50). Overall, patients categorized as responders in both programs showed a significant reduction in symptom severity three months after enrolment. Here, 42% of patients attending the eHealth program reported a mean IBS-SSS reduction of 109 points (p <.05) In addition, patients attending the eHealth program reported enhanced quality of life, especially the degree of dysphoria, body image, food avoidance, health worry, interference with activity, relations, and social relations. Patients responding to the physical IBS-school, reported no difference in overall quality of life. However, patients attending the physical IBS-school reported a significantly better satisfaction with the program, compared to the digital eHealth program. Interestingly, patients who were not considered responders to either program also reported a high client satisfaction.

CONCLUSIONS

We conclude that patient education is beneficial for most patients with IBS. However, patients benefit from different aspects of a multidisciplinary patient education program and a stratification of patient benefits needs to be further investigated in a larger cohort of patients.

UNSTRUCTURED

There are over 8 million central venous access devices inserted each year, many in patients with chronic conditions who rely on central access for life-preserving therapies. Central venous access device–related complications can be life-threatening and add tens of billions of dollars to health care costs, while their incidence is most likely grossly mis- or underreported by medical institutions. In this communication, we review the challenges that impair retention, exchange, and analysis of data necessary for a meaningful understanding of critical events and outcomes in this clinical domain. The difficulty is not only with data extraction and harmonization from electronic health records, national surveillance systems, or other health information repositories where data might be stored. The problem is that reliable and appropriate data are not recorded, or falsely recorded, at least in part because policy, payment, penalties, proprietary concerns, and workflow burdens discourage completeness and accuracy. We provide a roadmap for the development of health care information systems and infrastructure that address these challenges, framed within the context of research studies that build a framework of standardized terminology, decision support, data capture, and information exchange necessary for the task. This roadmap is embedded in a broader Coordinated Registry Network Learning Community, and facilitated by the Medical Device Epidemiology Network, a Public-Private Partnership sponsored by the US Food and Drug Administration, with the scope of advancing methods, national and international infrastructure, and partnerships needed for the evaluation of medical devices throughout their total life cycle.
Telemental healthcare for Latino cancer patients during the COVID-19 pandemic in Latin America, Spain, and United States (Preprint)
Authors: Costas-Muñiz Rosario
Published: October 2022

BACKGROUND

The COVID-19 pandemic is affecting the health and mental health of the general population, including Latino cancer patients with unique health, emotional, and socioeconomic concerns.

OBJECTIVE

To describe mental health professionals’ clinical practice and mental healthcare care delivery to Latino cancer patients in the US, Latin America, and Spain during the COVID-19 pandemic (2020 and 2021).

METHODS

Mental healthcare practitioners treating Latino cancer patients were invited to complete a web-based survey in two waves (first wave: May-July 2020; second wave: March-July 2021). Two independent samples completed the web-based surveys.

RESULTS

Of the samples of clinicians (approximately first n=80 and second n=146 waves), most reported decreased productivity in clinical activities, especially outpatient care (50% median decrease for 2020 and 30% median decrease for 2021). In 2020, one-fourth (23.7%) completely stopped treating patients, and in 2021, only 3.4% were not treating in person. Although half (51.3%) still met patients in person in 2020, and two-thirds (67.8%) in 2021, 76.9% reported having remote sessions with patients in 2020 and 93.8% in 2021. Factors associated with the delivery of sessions via video were gender and type of patient population and rural/urban location. Factors associated with delivering care via phone were gender, country economy, type of primary clinical work site, and patient age group, and patient socioeconomic status.

CONCLUSIONS

During the worldwide COVID-19 crisis, for Latinos with cancer, appointments for in-person mental health treatment stopped, were reduced, or transformed to remote care. There were indications of socioeconomic disparities in telehealth access. Studies should address remote mental healthcare implementation with Latino cancer patients at the individual, provider, and healthcare system levels and determine the eHealth/telehealth training needs of providers.
ON SOME FEATURES OF ULTRASOUND REFLECTION WATER-SAMPLE IN AN INCLINED FALL (PHYSICAL MODELING)
Authors: Fedin Konstantin , Lukyanowa Alina , Kolesnikov Yuriy
Published: October 2022

In recent years, the analysis of the dependence of reflection coefficients on the magnitude of the angle of incidence of reflected waves has been successfully used in the practice of seismic research. AVO analysis is one of the methods of dynamic analysis that is used to estimate changes in the amplitude of reflected waves depending on the distance between the explosion points and the receivers. The AVO method is based on the analysis of the dependence of the reflection coefficients on the angle of incidence. In real conditions, this dependence can be determined, for example, by the roughness of the boundaries. This determines the relevance of studying the features of reflection coefficients on uneven boundaries on objects with well-controlled properties. The aim of the work is to determine the nature of the influence of different-scale roughness of seismic boundaries on the reflection coefficients of elastic waves. The work also used the technique of isolating standing waves to determine the wave velocity. As a result, graphs were obtained demonstrating the dependence of the reflection coefficients on the magnitude of the angle of incidence of reflected waves from a rough surface. Reflection coefficients were also obtained for the boundary of an isotropic medium in the direction of the isotropy plane and possible ways of applying the results were analyzed. Based on the data obtained, we can say that when the azimuth changes relative to the direction of the surface, the reflection coefficients change significantly only at the supercritical angles of incidence.

The participants of this research are the author, together with her elder brother. Data were gathered from online personal diaries through blogger, digital journals, participants' memories and writings regarding ACEs, of which analyzed in the form of narrative themes. The result shows that changes could happen if a person reflects on themselves and find meanings through their experiences even though ACEs indeed had negative impacts in adulthood. Various meanings obtained through events wrien in autoethnography which then brings the author to the process of awareness, whilst enabling her to understand ACEs from different perspectives and build a new motivation to make efforts of overcoming the side effects of her past traumatic experiences. The research can provide insights for mental health professionals to help adults dealing with past trauma. Aside from that, autoethnography is part of therapeutic tools which are effective not just for the authors, but also the readers who faced the same struggles as the author, in this context, make peace with ACEs. This enhances the importance of doing the research, not only to benefit practitioners, but also for future readers who experienced ACEs itself.

This study investigated school climate and students’ academic achievement in public secondary schools in Anambra State. Three research questions and hypotheses guided the study. This is a correlational survey of the ex-post-facto research design. 127(50%) respondents were sampled from a population of 254 principals using a simple sampling technique. A self-developed questionnaire titled School Climate Questionnaire was employed to collect information from respondents. While a checklist was used to obtain information on students’ academic achievement. The questionnaire was validated through the face and content validity. It was also subjected to a reliability test using Cronbach-Alpha and a coefficient of .79 was obtained revealing a high-reliability index. Coefficient of determination, Pearson r, and Regression were used for data analysis. The finding shows that the relationship between teachers’ motivation, instructional supervision, school climate, and students’ academic achievement in Anambra State was significant. It was thus, recommended that since educational supervision enhances instructors’ professional competence and the effectiveness of their instructional activities school principals should ensure that the climate of the school enhances the teacher’s job.

Authors: Fitri Yanuar , Nainggolan Saidin , Ulma Riri Oktari
Published: October 2022

This research aims to; analyze the optimization model of the use of production inputs in order to increase production and the efficiency of potato farming. This study uses cross-section data from 62 farmers. Sampling was done by Simple Random Sampling. The approach taken to examine the response of production to inputs is made descriptively. The production and efficiency functions are estimated using the stochastic frontier production function and the dual cost function. The results showed that there was no optimal use of production inputs. The frontier production function was mainly determined by the input of seed production of SP-36 fertilizer, KCL fertilizer, and liquid insecticide. The determinants of optimal production are determined by the use of seeds, urea fertilizer, and the use of drugs. The optimal use of inputs can produce an optimal production of 21,768 kg, while the actual production is only 12,250 kg. The use of seeds, SP-36 fertilizer, organic fertilizers, liquid insecticides, and labor are risk-reducing productivity factors. The technical efficiency of potato farming is in the medium category (ET=0.6644). Sources of technical inefficiency mainly come from the land area, age, and distance of farming land. Meanwhile, income, farming experience education and the number of family members reduce the occurrence of technical inefficiency. Farmers' behavior in responding to productivity risks is the average risk taker.

Abstract: Higher education is the most contributing and paramount instrument in designing and redesigning the landscape and destiny of any country. Undeniably, it is always the key socio-economic device and has positively proportionate relation with any state’s GDP, Health indicators, industrial growth and multifaceted development. If it is not moved in the prospective dimension, the devastation it causes can be precarious and unpredictable too. Our Indian higher education, which is the largest in the world with 70 million enrolments, 1000 plus different universities and 45000 HEI,s is not an exception to this widely proved doctrine. As UN- General Secretary commented, ‘The Present notable COVID-19 disaster has triggered history’s biggest disruption of education, affecting 1.6 billion students worldwide (70% of the world student population) and some 23.8 million students may not be able to return to schools to next year because of economic fallout’. ‘It is critical that education is at the heart of international solidarity’. (The Hindu, 09-08-2020). The Research and other forms of scholastic endeavors, which indeed are more consultative and collaborative in nature, have completely paused desperately at greater extent and caused on insurmountable obstacle. Unfortunately, as in most other developing and underdeveloped countries, in India too, there were no predetermined pathways to combat and compete with the perlious pandemic type cataclysmic circumstances. Still we should enshrine with huge hope to face and fight the unprecedented challenges thrown by the pandemic.

Published: October 2022

Abstract: Shopping at large malls has become a commonplace activity in smart cities. This project is aimed to shorten the line at a supermarket's billing counter. The module displays the total price of the product stored in the cart. In this manner, the buyer can directly pay the amount at the billing counter and leave with the goods purchased. It replaces the traditional scanning of products at the counter, which speeds up the entire shopping process. Additionally, with this system, the user will know the total amount to be paid and can thus plan his shopping accordingly, only purchasing essential commodities, resulting in increased savings. Because the entire billing process is automated, the chance of human error is greatly reduced. In addition, the system contains a feature that allows the user to delete scanned products, which improves the customer's purchasing experience. The test hardware is based on the Arduino platform. There is also an app that communicates with the Arduino UNO board and displays a list of all the products purchased by the user as well as the produced bill.

Published: October 2022

Abstract: In this study behaviour and concept of Pre- Engineered structure & SSI is included. Behavioural study of preengineered building is observed in this paper. Soil structure interaction (SSI) taken into consideration to study the interface between Soil and the structure rested on that soil. Many resources can be used to gather information on the present theories and practices, including IEEE explorer, technical papers, journal, conferences, patent information research thesis, international and national workshop proceedings. The following case studies the influence of soil structure interaction on pre-engineered building (PEB). By considering the fixed support conditions at the base of structure, the structural behaviour is analysed. The structural response of building seems to be affected because in conventional method the foundation flexibility of soil mass has been ignored. Winkler’s spring model approach is used for the analysis of soil flexibility by integrating. The effect of SSI on various parameters like base shear, lateral displacement, etc. are studied and discussed. The subgrade must be modelled adequately well to get real behaviour of superstructure. The analysis is administered in STAAD Pro. connect edition software using response spectra of IS 1893-2016

Published: October 2022

Abstract: Cranial implants are utilised during the medical surgery known as cranioplasty to fill the deficiency and preserve the cranium's aesthetic, which eventually aids in fulfilling the patients' metabolic demands. There are several materials, each with unique benefits and drawbacks categorised into biological and synthetic material. The research of various structures that may be used in biomedical implants to replicate the structure or qualities of bone has been facilitated by the development of specific materials throughout history and improvements in manufacturing processes. One of the cellular structure types that is frequently utilised in biomedical implants is the lattice structure. This work models a cranial implant based on lattice structures. Body-centered cubic (BCC), Face-centered cubic (FCC), and fluorite were the three lattice structures that were selected. The effects of external load on cranial implants are next examined while considering two polymeric materials, Polymethylmethacrylate (PMMA) and Polyetheretherketone (PEEK).

Abstract: Since it is now vital to have female staff in factories and other commercial market segments, there hasbeen an upsurge in violent crimes and physical assaults against women. For women to work in fields that need them to travel at odd hours and go to isolated, In this project,when a woman senses danger, she must hold ON the device’s trigger. As soon as the gadget is turned on, it uses the GPS to determine the user’s current location and sendsan emergency message via the GSM (Global System for Mobile communication) to both the police stations and the registered mobile number. Our project focuses on a safety system that is expressly designed to fulfil that goal in order to avoid women from feeling helpless in the face of such social concerns.

Industri ban vulkanisir menguasai pangsa pasar lokal sebesar 25% dari total konsumsi karet alam domestik. Ban vulkanisir yang dapat memperpanjang umur pakai ban dengan menawarkan tingkat harga lebih rendah dibanding ban baru telah menjadi daya tarik bagi pengguna ban vulkanisir yang utamanya berasal dari industri transportasi umum dan logistik. Salah satu faktor penentu kualitas ban vulkanisir adalah pemilihan cushion gum sebagai perekat antara telapak ban baru dengan bagian kesing ban lama. Riset ini mempelajari pengaruh dosis bahan pelunak alami pine tar oil dan peningkatan kapasitas produksi terhadap mutu cushion gum. Dosis pine tar oil diatur sebesar 5 phr untuk pembuatan cushion gum skala laboratorium pada kapasitas 1 kg kompon/batch, dan 10 phr untuk cushion gum yang dibuat pada skala semi pilot kapasitas 10 kg kompon/batch. Hasil pengujian kompon dan vulkanisat lembaran karet cushion gum menunjukkan bahwa peningkatan dosis pine tar oil dalam formulasi kompon dan kapasitas produksi cushion gum dapat memperbaiki mutu lembaran karet cushion gum khususnya sifat perpanjangan putus namun menurunkan kemampuan proses kompon karet cushion gum tersebut.

Konsep desain penggunaan karet peredam gempa adalah energi disipasi, yaitu penyerapan gaya gempa sebelum masuk ke bangunan dengan cara pemisah struktur bangunan diatasnya dari tanah yang merupakan pusat sumber kedatangan gempa. Aspek keamanan pelaksanaan pembangunan terutama untuk perumahan rakyat seringkali terabaikan. Hal ini terutama berkaitan dengan pendetailan tulangan baja yang merupakan aspek penting dalam kriteria bangunan tahan gempa yang kerap kali terabaikan di dalam pelaksanaan baik secara tidak disengaja maupun disengaja dengan dalih menekan biaya pembangunan agar nilai bangunan lebih ekonomis. Dengan pertimbangan kedua permasalahan di atas, maka solusi yang paling elegan dan memungkinkan untuk negara berkembang seperti Indonesia dimana sebagian besar penduduknya menghuni perumahan rakyat daripada apartemen bertingkat adalah mengenalkan penggunaan karet peredam gempa. Karet peredam gempa berfungsi sebagai penyekat atau peredam agar gaya gempa sebelum merambat masuk ke struktur bangunan dapat diredam. Peredam gempa ini dikembangkan mulai dari teknik proses dan pembuatan bahan dasar kompon karet agar tepat sesuai dengan peruntukannya sebagai bahan isolator (pemisah). Untuk perkuatan digunakan lapisan reinforcement woven roving fiberglass sebagai pengganti pelat baja yang secara nilai ekonomi lebih inovatif dan dapat diaplikasikan. Aplikasi penggunaan karet peredam gempa dilakukan dengan pengujian material karet dan menganalisa karet peredam gempa tersebut secara numerik untuk menghasilkan sifat mekanik dan nilai redaman disipasi energi sebesar 9 persen. Nilai rasio redaman tersebut dimasukan ke dalam simulasi bangunan rumah tinggal tahan gempa menggunakan software ETABS dengan sebelas rekaman gempa yang pernah terjadi. Dari hasil simulasi diperoleh perilaku bangunan rumah tinggal menggunakan karet peredam gempa mampu menaikan performa bangunan, dari yang sebelumnya tanpa karet peredam gempa bangunan mengalami kerusakan saat terjadi gempa, setelah diaplikasikan karet peredam gempa bangunan tidak mengalami kerusakan.
SIFAT KARET MENTAH DAN VULKANISAT KARET ALAM DENGAN PENAMBAHAN ASAM AMINO

Published: October 2022

Pembuatan karet viskositas mantap biasanya menggunakan hidroksil amine sulfate (HNS) sebagai bahan penstabil viskositas yang ditambahkan ke dalam lateks karet alam. Akan tetapi HNS bersifat korosif sehingga perlu digantikan dengan bahan kimia lain yang tidak korosif seperti asam amino. Pada penelitian ini, penambahan asam amino (glisin dan arginin) ke dalam lateks karet alam diinvestigasi untuk memperbaiki sifat karet mentah, kompon, dan vulkanisat karet alamnya. Pada penelitian ini dosis asam amino (glisin dan arginin) yang digunakan disesuaikan dengan dosis HNS yang biasa diterapkan di dalam praktek, yaitu sebanyak 0,15% berat karet kering. Lateks karet alam dengan kandungan gel tinggi yang didapat dari pohon karet tua digunakan pada penelitian ini. Sifat karet mentah seperti sifat plastisitas, kandungan gel, plasticity retention index (PRI), dan kestabilan pada saat penyimpanan diobservasi. Sementara itu karakteristik pematangan dan sifat vulkanisat karet alam dikarakterisasi dengan menggunakan rheometer dan universal tension machine. Hasil penelitian menunjukkan bahwa penambahan asam amino dapat meningkatkan PRI dan untuk sampel yang mengandung arginin dan penstabil dapat menurunkan kandungan gel dan karet mentah stabil pada saat penyimpanan dibandingkan dengan sampel tanpa penambahan arginin dan penstabil. Dengan adanya penurunan kandungan gel di dalam karet mentah dapat meningkatkan derajat ikatan silang dari vulkanisat karet alam menyebabkan peningkatkan sifat kuat tarik karet alam. Arginin merupakan asam amino polar yang cocok digunakan untuk meningkatkan sifat karet mentah dan memudahkan pemrosesan serta menghasilkan peningkatan sifat kuat tarik vulkanisat karet alamnya.
POTENSI PENGGUNAAN KARET ALAM TERMOPLASTIK (COPOLYMER NR-VYNIL MONOMER) UNTUK ALTERNATIF MODIFIER ASPAL KARET: I.	PEMBUATAN KARET ALAM TERMOPLASTIK DARI KARET ALAM DAN MONOMER VINIL SECARA KOPOLIMERISASI CANGKOK EMULSI

Aspal karet merupakan salah satu bentuk aspal modifikasi polimer. Umumnya, aspal modifikasi polimer dibuat dengan mencampurkan modifier termoplastik elastomer sintetik jenis stirena butadiene stirena (SBS) ke dalam aspal. SBS berpotensi digantikan oleh karet alam termoplastik (Thermoplastic Natural Rubber, TPNR). Di Indonesia, pengembangan aspal karet skala lapangan telah diinisasi sejak 2016 namun belum menggunakan TPNR. Riset ini bertujuan untuk mempelajari karakteristik TPNR yang dibuat melalui kopolimerisasi cangkok emulsi karet alam protein rendah (DPNR) dengan kombinasi monomer vinil (MV) stirena (ST) dan metil metakrilat (MMA). Komposisi DPNR/MV diatur pada 60/40 bagian, sedangkan rasio kombinasi MV ditetapkan sebesar 1:2; 1:1; 2:1. Urutan penambahan MV diatur MMA dahulu diikuti ST, dan sebaliknya. Hasil eksperimen menunjukkan bahwa TPNR atau kopolimer cangkok yang disintesis dari DPNR dengan penambahan ST diikuti MMA pada rasio 2:1 (kopoli (DPNR/ST-MMA 2:1)) memiliki sifat yang paling mendekati SBS sehingga berpotensi digunakan sebagai alternatif modifier dalam pembuatan aspal karet.
WORKERS FLOW AND ON-TIME COMPLETION OF CONSTRUCTION PROJECTS

Published: October 2022

The construction sector is one of the most important economic activities since it is responsible for planning, designing, and developing the infrastructure that social development requires, such as roads, schools, and hospitals. Thus, the late completion of construction projects may harm social welfare. Construction companies have problems coping with completion times since they simultaneously manage multiple infrastructure projects that differ in the number of workers they need and the possibility of having projects whose development overlaps. So, companies split their projects into development stages to simplify the management of construction projects, which require an efficient allocation of workers to cope with the stages’ activities. This paper analyzes the distribution of workers among development stages to cope with the projects’ completion times. Noticing that not all workers should participate in the same development stage of a single project, the previous problem casts similarities with the maximum flow problem. We follow this modeling approach to determine the number of workers participating at each development stage when a company simultaneously manages more than one construction project. Later, we apply the previous model for a company that operates 11 projects and has 24 workers; the maximum workers’ flow model sets the number of workers that each development stage needs for the on-time completion of the 11 projects by considering three different scenarios, concerning the overlapping of development stages.
