Published: December 2021

The Covid-19 pandemic has caused recessions in many countries around the world. This happened after economic growth in the first and second quarters of 2020. Some of the countries experiencing recession are Singapore, South Korea, Germany, Japan, France, Hong Kong, and the United States. If the economic growth in each quarter is also negative, Indonesia will experience a recession. The Central Statistics Agency (BPS) noted that Indonesia's economic growth rate fell to minus (5.32%) in the second quarter of 2020. Previously, Indonesia's economic growth in the first quarter of 2020 was 2.97% or started to slow down. Inflation is a tendency to increase the prices of goods and services in general, which continues continuously, which will reduce the purchasing power of the public, especially for low-income groups. Therefore, it is hoped that there will be a control over the rate of inflation, especially during the Covid 19 Pandemic which had an impact on Indonesia's macro conditions. This observation discusses "The Impact of the Covid-19 Pandemic on Indonesia's Inflation Rate", aims to determine the effect of the Covid-19 Pandemic on the Level of Inflation in Indonesia. The results of this observation show that in March 2020 there was inflation of 2.96% year on year (yoy), with an increase in the price of gold jewelery and several food prices that experienced a quite drastic increase.

Ensuring A Better Water Future for Malaysia
Authors: Abdullah Academician Tan Sri Dato’ Ir. Shahrizaila
Published: December 2021

Human overuse of water resources and diffuse contamination of freshwater are stressing the water resources in the terrestrial water cycle. As a consequence, the ecological functions of water bodies, soils and groundwater in the water cycle are hampered and being further exacerbated by threats from impending climate change. Though Malaysia is blessed with fairly abundant rainfall it still has its fair share of water woes, such as occasional droughts, looding and pollution of its rivers and water bodies. Only recently, the country was faced with water related hazards of fairly disastrous proportions. Recurring potable water shortages that occurred in 2014 and 2015 in several states had led to water rationing. Malaysia has since the early 1990s set its vision to become a fully developed country by the year 2020 (Vision 2020). The transformation of the water sector must also evolve in tandem to meet sustainable development goals beitting a developed nation status by 2020. The National Water Resources Policy (NWRP), launched in March 2012, is based on the 3 essential principles i.e. water resources security, water resources sustainability and collaborative governance. This paper will review the various water-related issues and challenges whilst proposing the implementation of the Integrated Water Resources Management (IWRM) Road Map including the measures to be undertaken to effect the transformation of the water sector in pursuit of Vision 2020 and to achieve the post 2015 Sustainable Development Goals (SDGs). The indings and recommendations are largely based on several in-depth studies undertaken by the Academy of Sciences, Malaysia (ASM) pertaining to the water sector and the IWRM agenda.

Published: December 2021

The thermochemical behaviour of Co-Pyrolysis between Empty Fruit Bunches (EFB) and Palm Oil Mill Efluent (POME)  sludge were studied using Thermogravimetric Analysis (TGA). EFB, POME sludge, and their blends (EFB : POME sludge of 100:0, 90:10, 75:25, 50:50, 25:75, and 0:100) were studied at different heating rates (5, 10, 20, 30, and 40ºC/min) with nitrogen (N2) purge of 20 ml/min to simulate pyrolysis conditions. All the samples experienced three pyrolysis stages and for each stage, the mechanisms responsible were determined. During co-pyrolysis, a positive synergistic effect was observed in the  experiments, which is a favourable inding. With the increase in POME sludge percentage in the blends, the activation energy for the main decomposition stage (Stage 2) decreased from 89.33 kJ/mol to 63.47 kJ/mol, when the kinetic model was irst order reaction (F1).

Published: December 2021

Computer-Aided Molecular Design (CAMD) is a powerful tool for designing promising molecules with the targeted properties. Besides properties, the safety and health aspects must also be considered during design stage to ensure the synthesized molecules do not cause much harm. The molecules are assessed by several safety and health parameters, which are measured using physicochemical properties that can be estimated via property prediction methods. Each parameter/sub-index is allocated with a penalty score based on the property to represent the hazard level of molecules. However, uncertainty in the prediction models can adversely affect the accuracy of scores. The main highlight of this paper is to manage the effect of uncertainty on the safety and health sub-indexes, by improving the scores at the uncertain region for enhanced measurement of molecular hazards. A case study on solvent design for carotenoids extraction from Palm Pressed Fiber (PPF) has been considered with the proposed methodology.

Published: December 2021

The feasibility of using palm kernel cake and crude glycerol in liquefaction process to produce bio polyol was investigated in  this study. The identiied parameters for liquefaction conditions were reaction temperature, reaction time, biomass loading and  acid loading. The optimal liquefaction conditions for bio polyol production were determined to be 10%(w/w) biomass loading, 1%(w/w) acid loading, and reaction temperature at 160°C for 90min. The optimal condition yielded 83 % biomass conversion with hydroxyl and acid numbers of 552 mg KOH/g and 0.56 mg KOH/g respectively. Result shows that palm kernel cake and crude glycerol can be used as an alternative raw material and liquefaction solvent to the production of bio polyol.
Maximizing the Impact of Air Bubbles for Membrane Fouling Control in Microalgae Harvesting
Authors: Arthur Eliseus  , Muhammad Roil Bilad
Published: December 2021

Harvesting microalgae using membrane is challenging due to the nature of microalgae having very high membrane fouling potential. Numerous techniques have been proposed for membrane fouling control, including optimizing operational cycles, imposing shear-rates via air bubbles and dosing chemicals for feed conditioning and membrane cleaning. As an established  method, the eficacy of air bubbles for membrane fouling control can be improved by maximizing the impact of shear-rates in  scouring foulant from the membrane surface. In this study, we investigate the effect of tilting angles, switching periods as well as aeration rates in a lab-scale submerged iltration system by iltering microalgae solution. Results showed that higher tilting angles improve the cleaning eficiency by offering higher lux of up to 2.7 times at an angle of 20◦ as opposed to the vertical one. It was also found that operating a one-sided panel (without switching) was about 20% better than a two-sided panel, in which the latter involved switching mode to offer aeration of both panel sides. This technique is effective in controlling fouling and can lead to energy saving for full-scale modules.

Vou falar de memoria e a memoria é fráxil e selectiva, cada vez máis fráxil, máis selectiva, e máis politicamente incorrecta, por iso pido desculpas anticipadas se os feitos diverxen da realidade; pero isto pretende ser unha visión persoal, case introspectiva, da miña relación coa Táboa Periódica. Por onde comezar?…Nun exceso de orixinalidade, polo principio: o hidróxeno. É o primeiro elemento que me veu a mente á hora de establecer esta relación miña coa Táboa Periódica. As razóns poderían ser múltiples, pero elixamos a mais pragmática: Instituto de Bacharelato Xoán Montes, Lugo, Xuño de 1988. Oposicións de Agregados de Bacharelato. Tema a desenvolver: Ácidos e bases. Obviando o feito de que a famosa “transferencia de protóns” leve a confusións derivadas da incorrecta apreciación que resulta de empregar H+ en vez de H3O+, aí comeza todo o que teño que agradecerlle a ese transcendental elemento da Táboa Periódica. E non só polo soporte e estabilidade económica, senón por permitir que se me pague por facer algo do que desfruto.
Primo Levi, a Táboa Periódica e máis eu
Authors: Armesto Constantino
Published: December 2021

Volvín ler “A táboa periódica”, un fermoso libro escrito por Primo Levi. Se xa me gustaba cando se publicou en España no ano 2004, esta segunda lectura deleitoume, se cabe, aínda máis. O seu autor, químico de profesión, ademais de talentoso escritor, evoca varias aventuras humanas fascinantes, ligadas cada unha delas a un elemento químico. Comeza co argon, lembrando aos seus nobres antepasados; ségueo o relato dunha amizade de ferro; conta as desventuras que sofre quen confunde semellantes (ou substitúe o sodio polo potasio); o maleable e brando vanadio sérvelle para preguntarse se a pasividade ante o mal é responsable; o arsénico, arma para o cruel asasinato, tamén pode enxalzar a dignidade do perdón; o envelenamento que castigaba aos primitivos mineiros do chumbo é lendario; sublime a obtención do mercurio; e así sucesivamente con, nada menos que, vinte e un elementos. “Ao chegar a este momento da vida, que químico, ante a táboa periódica non recoñece, espallados por ela, os farrapos ou os trofeos do propio pasado profesional?… Ocorre, pois, que cada elemento lle di algo a cada un (a cada cal unha cousa diferente), igual que pasa cos vales ou as praias visitadas durante a mocidade”. Ao longo de todo o artigo atereime a estas indicacións. Inspirándome en Primo Levi quero lembrar os elementos da táboa periódica que me gustan e as historias que me suxiren; non comentarei as súas propiedades, obtención ou reaccións, tampouco destacarei a súa importa química ou económica, describirei as distintas ideas, nostalxias e emocións que espertan en min; porque eses coñecementos e esa paixón téntolla comunicar aos meus alumnos.
A Táboa Periódica na Química Inorgánica
Authors: Bermejo Manuel R. , González-Noya Ana M. , Maneiro Marcelino , Pedrido Rosa
Published: December 2021

No século XVIII non había táboa periódica, pero si existía xa a Química Inorgánica, que os franceses chamaban “Chemie Minerale”. Ata finais do século XVIII e desde os tempos alquímicos, as químicas de todos os tempos miraban canto estaba ao seu redor e investigaban para coñecelo mellor e utilizalo na súa vida cotiá. Deste xeito foron descubrindo e utilizando os chamados metais clásicos (Au, Ag, Cu, Sn, Fe, Pb, e Hg), tamén o carbono e o xofre, e logo foron aparecendo moitos outros elementos químicos. Así ata 33 elementos, que os Lavoisier colocaron na súa Táboa das sustancias simples do seu libro “Tratado Elemental de Química”, no que incluíron tamén sustancias que erroneamente consideraron elementos. Incidentalmente anotaremos que, dende os filósofos clásicos (hai máis de 2300 anos) se enunciaron e se aceptaron como Elementos-Principio: a Auga, a Terra, o Aire e o Lume. Estes Elementos, enunciados como tales por Aristóteles, foron recuperados por Tomás de Aquino e os escolásticos para seren propagados no tempo ata chegar ao século XVIII, no que foron agrupados por G. Stahl na súa Teoría do Floxisto. A finais do século XVIII (entre 1780-1789) será o matrimonio Lavoisier quen, paseniño, irá desmontando esta teoría do floxisto ao demostrar que non se trataba de elementos, senón que eran compostos integrados por varios elementos químicos distintos. Nese derradeiro terzo de século o mundo da química era un auténtico caos: estábanse descubrindo novos elementos, pero tíñase pouca seguridade de que foran auténticos e novidosos. Tíñanse preparado moitos compostos, pero cada un era chamado como lle petaba ao seu descubridor, e mesmo un mesmo composto tiña diversos nomes en función de que investigador o citaba. Existía unha teoría, a do Floxisto, que semellaba ser incorrecta e non seguida por todos. Non existía unha linguaxe común, coa que todos se puideran entender. Non había unha linguaxe institucionalizada, como sucedía nas matemáticas e na física, na que todos cantos as practicaban puideran expresar as súas ideas e comunicarse,…etc. En resume, a Química non era, aínda, unha ciencia institucionalizada, como o eran as Matemáticas e a Física.

Published: December 2021

This study aimed to uncover the internal and external factors driving Millennial consumers to engage in Online Video Advertisements (OVAs) sharing. Underpinned by the Theory of Planned Behaviour (TPB), the internal factors tested in this study were attitude, subjective norms, and perceived behavioural control. The external factors predicted to influence consumers’ intention and actual sharing behaviour of OVAs were company reputation, brand awareness, and celebrity endorsement were underpinned by Stimulus Organism Response Model (S-O-R). The study included perceived intrusiveness as a moderator between the aforementioned antecedents and the sharing behaviour of OVAs. A total of 220 Millennial respondents was collected in Selangor, Malaysia. Partial Least Squares Structural Equation Modelling (PLS-SEM) analysis showed that attitude and subjective norms significantly predict consumers’ intention to share OVAs. In terms of external antecedents, only celebrity endorsements were found to positively influence the sharing intention of OVAs. The study also revealed that perceived intrusiveness negatively moderates the effects of attitude and social norms on the intention to share OVAs.

Published: December 2021

OBJECTIVE: To investigate the uptake and usage of a WhatsApp-based interactive communication strategy to avert pre-diagnosis loss to follow-up (LTFU) from TB care in a high-incidence setting.METHODS: We enrolled adults (≥18 years) who underwent routine sputum TB
testing in two primary healthcare clinics in Khayelitsha, Cape Town, South Africa. The intervention consisted of structured WhatsApp-based reminders (prompts) sent prior to a routine clinic appointment scheduled 2–3 days after the diagnostic visit. Pre-diagnosis LTFU was defined as failure
to return for the scheduled appointment and within 10 days.RESULTS: We approached 332 adults with presumptive TB, of whom 103 (31%) were successfully enrolled; 213 (64%) did not own a WhatsApp-compatible phone. Of 103 participants, 74 (72%) actively responded to WhatsApp prompts;
69 (67%) opted to include a close contact in group communication to co-receive reminders. Pre-diagnosis LTFU was low overall (n = 7, 6.8%) and was not associated with failure to respond to WhatsApp prompts.CONCLUSION: In this high-incidence setting, enrolment in a WhatsApp-based
communication intervention among adults with presumptive TB was low, mainly due to low availability of WhatsApp-compatible phones. Among participants, we observed high message response rates and low LTFU, suggesting potential for interactive messaging services to support pre-diagnosis TB care.

BACKGROUND: The surgical treatment for non-tuberculous mycobacterial pulmonary disease (NTM-PD) has an important adjunctive role and reported outcomes have been generally good; however, the prognostic factors remain unclear.METHODS: Sixty-one patients with NTM-PD who
underwent surgical resection for a therapeutic purpose from January 2000 to March 2017 at five affiliated institutions were enrolled. We explored the factors that influence complications and prognosis by retrospectively referring to the medical records.RESULTS: The mean age of the
present cohort was 61.8 ± 11.4 years. The pathogen was Mycobacterium avium complex in 49 patients, M. abscessus in 5. The most common indications were refractory to medication in 39. The surgical techniques employed were lobectomy or further resection in 49, sublobar resection
in 8, with video-assisted thoracoscopic surgery in 21. Sputum culture conversion rate was 95.1%. Univariate analysis of factors associated with deterioration revealed significant differences related to age (P = 0.025), pre-operative albumin level (P = 0.001) and development of
postoperative complications (P = 0.037), while pre-operative albumin level alone was a significant factor in multivariate analysis (P = 0.009).CONCLUSION: Outcomes after resection were generally good in the present cases. Nutritional status, as indicated by albumin
level, may affect prognosis after surgical treatment.
Prognozowanie stanu bezpieczeństwa narodowego
Authors: Wyrębek Henryk
Published: December 2021

Utrzymanie bezpieczeństwa narodowego jest jedną z podstawowych funkcji każdego kraju. Bezpieczeństwo narodowe obejmuje problematykę przeciwstawiania się wszelkim zagrożeniom jego istnienia i rozwoju zarówno zewnętrznym,
jak i wewnętrznym. Jest to uwarunkowane ewolucją i funkcjonowaniem środowiska międzynarodowego, w którym powstają różnorodne zagrożenia i wyzwania, a także jest uwarunkowane również potrzebami bezpieczeństwa wewnątrz struktury społeczeństwa. Biorąc pod uwagę fakt, że pojmowane powszechnie bezpieczeństwo ma związek bezpośrednio z zagrożeniami zewnętrznymi, to istotne znaczenie przypisywane jest polityce zagranicznej kraju, a całokształt przedsięwzięć zmierza do ochrony jego suwerenności. Prognozowanie bezpieczeństwa narodowego jest konieczne, a już na pewno należy do obowiązków każdego decydenta, który jest odpowiedzialny w szczególności za kwestie bezpieczeństwa wewnętrznego. Świadomi szefowie czy przywódcy powinni, a nawet muszą planować przyszłość swojego kraju, swojej organizacji czy jakiejkolwiek instytucji i to jak najdokładniej na nadchodzące lata. Ważne jest umiejętne prognozowanie stanu bezpieczeństwa, gdyż posiadanie wizji przyszłości, poczynionych planów, może być pomocne w zapobieganiu czy przeciwdziałaniu różnego rodzaju zagrożeniom.

Kara pozbawienia wolności oraz inne formy izolacji osób naruszających porządek prawny i zagrażający bezpieczeństwu innych jednostek należą do najdalej idących form ingerencji w sferę praw i wolności człowieka. Izolacja penitencjarna pociąga za sobą wiele negatywnych następstw dla jednostek inkarcerowanych, wśród których szczególne miejsce zajmują sytuacje i zjawiska zagrażające zarówno bezpieczeństwu podopiecznych instytucji penitencjarnej, jak i personelowi odpowiedzialnemu za stworzenie bezpiecznych warunków przebywania w czasie izolacji. Precyzyjne określenie zagrożeń bezpieczeństwa osobistego osób izolowanych i personelu jest niezwykle trudne. Trzeba pamiętać, że charakter tych zagrożeń nie jest jednorodny, a intensywność i zakres oddziaływania bardzo zróżnicowany. Wśród zjawisk i sytuacji stwarzających zagrożenie dla bezpieczeństwa osobistego
wymienia się: zjawiska związane z podkulturą więzienną (różne formy agresji, samouszkodzenia, tatuaże) czy procesem prizonizacji, zamierzone i niezamierzone działania lub zaniechania ze strony administracji oraz działania środowisk przestępczych wewnątrz i na zewnątrz jednostek izolacyjnych.

Autor artykułu przedstawia wyniki badań przeprowadzonych w styczniu i lutym 2021 r. wśród personelu zespołów ratownictwa medycznego w Polsce oraz Belgii dotyczących zmian i trudności w niesieniu pomocy medycznej ofiarom przemocy domowej w związku z pandemią koronawirusa SARS-CoV-2. W artykule omówiono także aktualne zalecenia Europejskiej Rady Resuscytacji dotyczące pomocy poszkodowanym zakażonym koronawirusem. Na podstawie analizy wyników badań przedstawione zostały zdiagnozowane przez personel zespołów ratownictwa medycznego zmiany w niesieniu pomocy medycznej ofiarom przemocy domowej w związku z pandemią COVID-19. Z uwagi na ograniczenia techniczne wynikające z panującej pandemii badania zostały zawężone do grupy pięćdziesięciu osób i nie powinny być odnoszone do ogółu personelu zespołów ratownictwa medycznego.
Three-phase inverter with a variable control algorithm
Authors: Szerszeń Grzegorz , Zygadło Damian
Published: December 2021

The paper presents the construction of a three-phase frequency converter with the possibility of choosing the type of PWM modulation and a smooth change of the frequency of the modulated signal. In a practical way, various inverter control algorithms were implemented in the same hardware system using the STM ARM Cortex M3 processor. The use of THIPWM modulation allowed to reduce the harmonic content in the output signal and effectively use the possibilities of the power source. The system can choose one of two scalar control algorithms, with the option of compensation for the influence of the stator resistance on the motor shaft torque in the initial range of the linear control characteristic at a constant voltage to frequency ratio. The research confirmed that the most advantageous type of PWM in this system is unipolar double-edge modulation. The use of the THIPWM method resulted in a gain in the amplitude of the fundamental harmonic of the output voltage for the three-phase inverter operation mode compared to the SPWM method. The appropriate precision of the frequency control step was also obtained, and the test results confirmed the functionality of the converter.

Authors: TRADECKI Piotr , Pałka Wojciech
Published: December 2021

The paper describes analyses of soils taken from open shooting ranges to find pollutants in the form of selected heavy metals. Test samples were taken from closed shooting ranges located in Wloclawek commune. During the investigations the content of following elements was identified: Zn, Pb, Cd, Cu, Ni, Co, Fe, As. The characterization of investigated localizations was also made with evaluation of samples of soils according to the Regulation of the Minister of Environment from 01 September, 2016 on the assessment of ground surface pollution. Studies confirm the relationship occurring between the effects of carried out shooting activities and the degree of accumulation of selected heavy metals elements in the soil of open shooting ranges. Indications show that this is sometimes a very complex issue and if neglected it can cause in the future a serious threat.

Wargames go back to the beginnings of human civilization and continuously accompany its development, shaping the course of history for over three thousand years. Organized and conducted in various forms, they influenced and created interstate and international relations in the diplomatic and military, economic and social dimensions. Countries, wanting to secure their vital interests and striving to preserve or expand their spheres of influence, used and still use wargames in their decision-making processes.
Wargames, initially taking the form of simple board games, thanks to research and scientific achievements (including initially the development of print, maps, game theory, computer technology etc.), have today taken the form of professional tools allowing for the optimization of the use of the most often limited resources in the decision-making process, both in the institutional dimension (governmental and non-governmental organizations) and emotional (in social and interpersonal relations).
As the course and support of decision-making processes plays an extremely important role in the security sciences, experience and historical analysis show that wargames have been and are also an essential tool for shaping the state's security.

Recently, Indonesia has been rapidly developing public transport infrastructure. However, many people still prefer using a private vehicle for their daily mobility. This study explored the design direction of an electric bike sharing system (EBS) for the first mile/last mile (FMLM) as part of an integrated public transport system to attract more people to public transportation. A focus group interview (FGI) was performed with ten Indonesian students currently studying at Daegu City, South Korea. All of them had experience using public transportation in both Indonesia and South Korea. From the FGI, the data on user needs related to FMLM was analyzed to understand the gap between expectations and reality as well as to enhance the feasibility of the design and development of EBS. In the next stage, based on the various needs and expectations of the participants about ideal public transportation in Indonesia, design strategies and elements were achieved and optimized specifically for EBS. Furthermore, we propose two usability scenarios in order to meet the user requirements. This study will be proposed to traffic policymakers for use in developing a design strategy and direction for an eco-friendly EBS formulation.

This study investigated the perception of Physical Education (PE) teachers on barriers to implementation of PE pro[1]gramme in terms of the administration of PE programme, and the provision of non-human resources. A total of 248 PE[1]major teachers were surveyed using questionnaires which were mailed to schools. The sample consisted of almost 63% male teachers and the majority was under 40 years of age. A 12-item questionnaire was used to assess the administration of the PE programme, and the provision of non-human resources. Results showed that a majority of administrators did not assume PE important; they did not seek consensus in assigning teaching duty, did not discuss teaching and learning factors, and did not organize staff training programme (STP). Older teachers and teachers with 15 years of teaching ex[1]perience or more agreed that administrators discuss their teaching assignment, observe them, and organize STP. Respon[1]dents also perceived inadequacy of facilities, equipment, financial allocation, and reference books in the school PE pro[1]gramme. Male teachers, younger teachers and teachers with less teaching experience concurred the inadequacy of human resources. It is recommended that further research on solving PE human resource problems and PE administration be undertaken. Specifically, greater attention should be given to the needs of younger and junior PE teachers.
