The use of Serious Games in education has experienced rapid development. However, not all studies have been able to show evidence that game-based methods are superior to other methods. It is important to analyze the quality of game designs used in learning and assessment used to assess students. This study focuses on how to design a serious game called B-block used in the assessment. The researcher validates the quality of the serious game first before conducting a pilot study regarding the feasibility of the Serious Game given for assessment. The game focuses on basic arithmetic, including addition, subtraction, division, and multiplication, and involves positive and negative numbers. The study was conducted in one of the schools in Indonesia and given to 35 students with an age range of 11-12 years with different student backgrounds in their experience with game-based exams. Based on these results, 85.7% of respondents agreed that this game could be used as a substitute for paper-based exams, with the analysis of game design quality having an average value of 78% pedagogic specifications and 73% playful and 80% technical specifications. Thus, the average value of this game quality analysis is considered superior and meets almost all the specifications needed for assessment. We also argue that serious game is closely related to how game design meets specifications for use as educational tools.

Introduction. The cost of construction is the most important indicator of any investment and construction project which is subject to change at every stage of its lifecycle due to the influence of many internal and external factors. Creation of an effective integrated construction cost management system, which allows controlling changes in construction costs in the process of developing a construction facility, is relevant for all participants of investment and construction processes. Certain methods and tools are applied at every lifecycle stage of a construction facility; they solve construction cost management problems. At the stage of capital investment planning and preliminary design, the main task is to determine trustworthy construction costs and possible limits of their change, taking into account any risks and uncertainties. This task turns more complex due to the lack of initial data about the facility and tight deadlines. This article is focused on the system of methods and practical tools used to determine construction costs at the stages of capex planning and preliminary design of a construction facility.

Materials and methods. In the course of the study, current construction cost calculation methods were analyzed. Methods of analysis, synthesis, expert and comparative evaluation were applied.

Results. As a result of the analysis the main principles of this methodological approach and a set of practical tools were developed to find reliable construction costs.

Conclusions. The proposed methods and practical construction cost management tools can be applied in the process of implementation of investment and construction projects of any complexity.
The effects of organic planting medium on growth and root formation of tea seedling at early stage of tea nursery
Authors: Dalimoenthe Salwa Lubnan
Published: February 2023

Tea plants commonly propagated through vegetative propagation using single node leaf cutting and planting on mixed of topsoil and subsoil. From time to time, it is difficult to get suitable soil for nursery and the activity could disturb ecosystem. In addition, the medium weight would become a constraint in transporation of tea seedling. To overcome these problems, an alternative planting medium of tea seedling has to be explored to reduce the use of soil. In this research, various organic materials have been tested to know their effect on growth and root formation of tea seedling at early stage of tea nursery. The experiment arranged in a complete randomized design with nine treatments, replicated three times. Treatments tested were combination of organic matter (cocopith, rice husk, sawdust, and peat soil) with top soil (15% and 25%). Cow dung, as organic fertilizer, was added to enrich planting medium. Results shows that cocopith, rice husk, sawdust, and peat soil enriched with cow dung resulted the same with top soil medium (convensional planting medium) on growth and root formation of tea seedlings at early stage of tea nursery.

Authors: Dalimoenthe Salwa Lubnan
Published: February 2023

In Indonesia has been found 11 cinchona species but only two species recognized as an economically important Cinchona succirubra known as resistant plant to root disease while Cinchona ledgeriana quinine high content. To put together those two characters from mostly through grafting it took twelve months. Micrografting is one of the propagation techniques through tissue culture. Micrografting has already been used in wide spread for plants propagation either only for research or as mass product. Hopefully, the use of micrografting to obtain cinchona propagation would be short more or less 10 months and provide plants as mass production economically. The result showed that micro grafting at V shape could be used as the propagation method on cinchona species besides bud multiplication through tissue culture. MS medium is the best medium for cinchona micrografting. If there is no IBA on rooting media, there is no root formation from the plants. The increasing of IBA from 1 up to 4 mg/l in media, will increase also the number of rooting plants.different plant material as scion and stock and different concentrarions (0,1,2,3,4 mg/l) of IBA gives the significantly different respons on rooting formation. The increasing of IBA on media will increase the number of rooting plants also. The highest rooting formation are found on medium with 3 danÂ  4 mg/LÂ  IBA. The combination between C. ledgeriana-C. succirubra, C. ledgeriana-C.ledgeriana, C. succrirubra-C.succirubra gives significantly difference on the growth dan development of root. The use of C. ledgeriana as a root stock doesnâ€™t showed good rooting formation. The combination between CSA/QRC205 gives the highest number of leaves result compare wth others combination on as much as 9,8.

Suppply chain analysis of Indonesia tea
Authors: Suprihatini Rohayati
Published: February 2023

Indonesian tea market share tend to decrease due to the weakness of competitive advantage of Indonesian tea. The weakness of Indonesian tea competitiveness should be cla-rified by supply chain. Primary data collected from survey as well as expert meeting. Analysis method applied in this research is supply chain analysis. Research results showed that in term of Indonesia tea production of 165.070 tons in 2006, tea volume to be processed to down-stream products for domestic consumption is around 62.776 tons. The rest is for export pur-poses consists of bulk black tea export (92.763 tons) as well as bulk green tea export (9.531Â tons). This condition relatively stable up to 2013 due to Indonesia tea import volume around 20,000 ton disburse to domestic con-sumption (55%) as well as re-export purposes (45%). The most of smallholder tea production (63%) come to jasmine tea processors located in Central Java. Farm gate price of green leaf is around 15,8% of consumer price of jasmine tea. Total margin of supply chain from tea farmers to jasmine tea consumers is around Rp22.100,00/kg of made tea consists of Rp13.121,00/kg made tea (50% of total margin) as cost margin and Rp8.979,00/kg made tea (34,1%) as profit margin. To remedy supply chain of smallholder tea should remedy factors affecting supply chain. Priority factors should be improved i.e. (1) quality of tea in each chain, (2) availability as well as assistancy to credit access, and (3) conducive of trade policies.

Among problems encountered in the availability of quality seedlings in nurseries is a low percentage of seedlings ready to plant. The seedling will remain stunted if no treatment is provided. Therefore, there must be some treat-ments carry in the nursery, as increase seedling ready to plant. One of the problems causing lack of good seedling growth is less than optimal growth and the role of the root, thus, the increase in the growth of the tea plant seeds can be cultivated among others through im-proved root system. The objective of this re-search was to determine the effect arbuscular mycorrhizal fungi (AMF) and plant growth regulator (PGR) against the percentage of root seedlings were ready to plant. Root growth can be accelerated by the application of PGR roots, ability to function and role of the roots can be improved by application of biological fertilizers such as AMF. The experimental design used was a randomized block design combined con-centration of PGR roots consisting of Z0: 0 mg/mL; Z1: 25 mg/mL; Z2: 50 mg/mL; Z3: 75 mg/mL with a dose of FMA consisting of: F0: 0 g FMA/plant; F1: 5,0 g FMA/plant; F2: 7,5 g FMA/plant and F3: 10,0 g FMA/plant. The experiment was conducted at the Gambung Experimental Station at the Research Institute for Tea and Cinchona, Bandung, West Java, at a height of Â± 1.350 m above sea level with the type of Andisols. Rainfall including B-type according to the classification of Schmidt and Fergusson (1951). The experiments resulted in the conclusion FMA 7,5 g dose combination treatment plants PGR-1 with a concentration of 25 mg/mL root, generating growth in both the percentage of root infection, seedling height, the number of leaves, and the amount of leaf chlorophyll and the percentage of tea planting material. The treatment resulted in a 35% increase in plant height, a number of leaves nearly 68% and the amount of chlorophyll is 83% higher compared to treatment without the FMA and without PGR. The percentage of 12 months old planting material with treatment reached 78,11% higher than the treatment without AMF and PGR which reached 49,28%.
Graph-theoretic approach to Bell experiments with low detection efficiency
Authors: Xu Zhen-Peng , Steinberg Jonathan , Singh Jaskaran , López-Tarrida Antonio J. , Portillo José R. , Cabello Adán
Published: February 2023

Bell inequality tests where the detection efficiency is below a certain threshold ηcrit can be simulated with local hidden-variable models. Here, we introduce a method to identify Bell tests requiring low ηcrit and relatively low dimension d of the local quantum systems. The method has two steps. First, we show a family of bipartite Bell inequalities for which, for correlations produced by maximally entangled states, ηcrit can be upper bounded by a function of some invariants of graphs, and use it to identify correlations that require small ηcrit. We present examples in which, for maximally entangled states, ηcrit≤0.516 for d=16, ηcrit≤0.407 for d=28, and ηcrit≤0.326 for d=32. We also show evidence that the upper bound for ηcrit can be lowered down to 0.415 for d=16 and present a method to make the upper bound of ηcrit arbitrarily small by increasing the dimension and the number of settings. All these upper bounds for ηcrit are valid (as it is the case in the literature) assuming no noise. The second step is based on the observation that, using the initial state and measurement settings identified in the first step, we can construct Bell inequalities with smaller ηcrit and better noise robustness. For that, we use a modified version of Gilbert's algorithm that takes advantage of the automorphisms of the graphs used in the first step. We illustrate its power by explicitly developing an example in which ηcrit is 12.38% lower and the required visibility is 14.62% lower than the upper bounds obtained in the first step. The tools presented here may allow for developing high-dimensional loophole-free Bell tests and loophole-free Bell nonlocality over long distances.
Enabling Multi-programming Mechanism for Quantum Computing in the NISQ Era
Authors: Niu Siyuan , Todri-Sanial Aida
Published: February 2023

NISQ devices have several physical limitations and unavoidable noisy quantum operations, and only small circuits can be executed on a quantum machine to get reliable results. This leads to the quantum hardware under-utilization issue. Here, we address this problem and improve the quantum hardware throughput by proposing a Quantum Multi-programming Compiler (QuMC) to execute multiple quantum circuits on quantum hardware simultaneously. This approach can also reduce the total runtime of circuits. We first introduce a parallelism manager to select an appropriate number of circuits to be executed at the same time. Second, we present two different qubit partitioning algorithms to allocate reliable partitions to multiple circuits – a greedy and a heuristic. Third, we use the Simultaneous Randomized Benchmarking protocol to characterize the crosstalk properties and consider them in the qubit partition process to avoid the crosstalk effect during simultaneous executions. Finally, we enhance the mapping transition algorithm to make circuits executable on hardware using a decreased number of inserted gates. We demonstrate the performance of our QuMC approach by executing circuits of different sizes on IBM quantum hardware simultaneously. We also investigate this method on VQE algorithm to reduce its overhead.

Published: February 2023

Amylases are the digestive enzymes belong to the family of glycoside hydrolase capable of hydrolysing starch and polysaccharides. These are the recent breakthroughs in food, feed, pulp and pharma industries. Our aim of this study is to purify amylases from Bacillus subtilis and Bacillus megaterium and optimize the growth conditions to achieve the cost-effective production of amylases from bacillus species. Extensive research on amylases from different sources is essential in producing enzymes in large scale and in optimizing the growth conditions and minimize the production cost to meet the increased demand of these industrially important enzymes. Amylases were produced in the current study using submerged fermentation and purified the extracellular enzymes from bacillus species using ultracentrifugation, Ammonium sulphate precipitation and gel filtration chromatography. There was no effect on amylase production from bacillus species when the initial substrate concentration is increased from 1% to 5%. Increase in inoculum size from 1% to 5% and the addition of yeast extract to broth had significantly increased the amylase production. The study observed significantly higher levels of amylase production using rice starch when compared with wheat starch also higher levels of amylase production observed with B. megaterium when compared with B. subtilis. The study concludes 1% rice starch and 5% B. megaterium inoculum can be used for cost effective production of amylases. In the current study, cost effective amylase production was evaluated and able to optimize the yield of extracellular amylases from Bacillus megaterium to a concentration level of 120 IU/ml of fermentation broth.
Deposit insurance for New Zealand: New scheme for the banking industry
Authors: Amanda Citra , Pradipta Ananta Dian
Published: February 2023

Using recent data from the New Zealand banking industry, this paper examines the most important factors that determine bank risk. We use a sample of 24 banks in New Zealand from the period from 2012 to 2021, using quarterly data. The risk-based deposit premium is preferable to be implemented in New Zealand as it calculates the risk attached to each bank as the flat rate is simpler yet imposes moral hazard. Thus, we use a weighting method based on statistical learning models using gradient boosted model to predict the most important variable that explains bank risk. The result shows that capital equity is the most important variable that can predict bank risk that weighs more than 40%. This research indicated that a risk-based premium is preferable and fairer than a flat-rate premium to reduce moral hazard (Bloecher et al., 2003). This study supports the deposit insurance schemes in New Zealand as a part of the system to maintain banking stability (Cerrone, 2018)
Single-cell detection of DMSO promoted HL-60 differentiation towards granulocyte based on DC-iDEP for medicine screening

Published: February 2023

Acute leukemia is the most common form of leukemia in adults. Drug
differentiation control is critical for the treatment of acute leukemia.
Unfortunately, current techniques detecting differentiation control
experience long time and complex steps of verification hindering the
steps of medicine discovery: flow cytometry and RT-PCR are highly
accurate and efficient at a cost of inconvenient fluorescent labeling or
a high risk of contamination; conventional staining leads to cell death
unavailable for further pharmacological tests. Simple, fast and
non-invasive techniques for medicine screening are in demand. DC-iDEP is
an emerging label-free identification technique sorting cell populations
taking advantage of the whole cell native biophysical property. Here,
HL-60 cell line has been used as a model to study the differentiation
process towards granulocytes and medicine efficacy. The results showed
that DEP could detect the DMSO promoted differentiation degree by the
weighted average characterization factor. This factor is related to the
single cell biophysical property, which accumulate to generate
differences in each population with distinct constitutions. Furthermore,
chichoric acid was first found to promote DMSO-induced differentiation
efficiently. The change induced by chichoric acid has been detected by
DEP for primary medicine screening application. A rapid, label-free
medicine screening method has been established monitoring HL-60
differentiation towards granulocyte for control and has great potential
for medicine screening.

Influences of six oil recesses shapes on the performance characteristics
of hydrostatic thrust bearings is discussed by using CFD methods. The
performance in terms of oil film pressure, temperature and load carrying
capacity is calculated. The recess pressure increases with its
circumference, the variation of maximum and the minimum recess pressure
in six recess shapes is 9%. The load carrying capacity (LCC) increases
with the recess circumference, and the maximum on equilateral triangle
recess while minimum pressure on circular. The LCC decreased 16.46%
when the rotation speed from 0 to 5000rpm. The recess shape have no
significant influence on the temperature distribution of oil film, but
the average temperature is inversely proportional to the width of middle
circle. Finally, the experiments were carried out to validating the CFD
methods.

The domestic pig (Sus scrofa) and subfamilies have a long-term and
extensive gene flow, especially in Southeast Asia. Demographically, as a
gateway of southern China, Yunnan province with unique geographical
location and complex climate system, but genomic, genetic introgression
of Yunnan indigenous pigs is insufficient. Here, we analyzed population
structure, differentiation, gene flow, adaptive introgression, signature
selection and gene function of Yunnan indigenous pigs, European
commercial and other Southeast Asia pigs using a pig genomics reference
panel (PGRP v1) from pig Genotype-Tissue Expression project (PigGTEx).
In this study, we clarified that the Diannan small-ear pig owned
particular genetic information in the whole genome; we provided evidence
of the introgression events from the Vietnam pig to the Diannan
small-ear pig. We also outlined at least two conceptual routes of gene
flow to Diannan small-ear in Southeast Asia. Three introgressed loci
with similar chromosome positions and strong signature selection
harbored the NAF1, NPY1R and NPY5R genes, which related to fat mass,
immunity, and litter weight of pig complex trait using multiple
bio-functionalization databases. Conclusively, these results laid the
foundation for understanding introgression from Southeast Asia pigs to
Yunnan indigenous pigs and provided a new insight into explaining the
biological function of genes through multiple databases.

Nowadays considering that cycling as a widely increasing daily transport mode is becoming more popular and also more publicly required among all kinds of interest groups of our society, municipal policies and practical activities for local cycling developments are already steadily growing and will be a substantial part of municipal statutory development planning in Latvia, too, and that needs modern adaptive governance application and must be properly integrated within necessary sustainable municipal mobility approach. The study starts with an overview of the municipal cycling governance developments in Latvia as the aim of this research is to study the municipal cycling governance building frame, via the complementary set of cycling governance instruments application in terms of their development, implementation and impact evaluation – political and legal, institutional, planning, economic, infrastructure and also communication instruments. As the model’s case study area, Valmiera township municipality (case of medium and small size town municipalities in Latvia) was chosen, where our sustainable mobility studies have been step-wise continuing from 2016, particularly participatory documenting the cycling mobility development and its governance as sub-system of municipal mobility/transportation governance. The research methodologies applied included both research-and-development framework, being realized in active collaboration with municipal administration, and, case study research, allowing to provide integrative contextual analysis of the case phenomenon, including document studies, infrastructure observations with photo documentation, followed by semi-structured in-depth interviews with whole set of the main stakeholders. The study highlights direct necessity of the particular cycling mobility governance system approach understanding and adaptive application, based on three governance dimensions (governance content, stakeholders and instruments). Besides social-ecological system as governance content dimension approach and stakeholders’ participation as governance stakeholders’ dimension approach, also and particularly, not only to use usually emphasized infrastructure planning, but further design and complementary use of all groups of traditional governance instruments, also additionally developing adaptive governance based disciplinary/sectorial cycling mobility instruments, esp. whole set of cycling communication instruments (information, education/training, participation, pro-cycling friendly behaviour). This triple governance dimensions’ model and principle as well as action policy recommendations elaborated may be used by the other local municipalities starting to expand cycling mobility.

Published: February 2023

Public services and demands for increasing efficiency of the public administration have been in public spotlight and on the political agenda for at least last twenty years in Latvia. In Europe and the USA this trend has been going even longer. Nevertheless, the public services and their systems are still object of the research. The aim of this study is to test the suitability of the system of systems (SoS) approach for describing and researching public service system and to identify new dimensions in the understanding of the public services. The SoS approach means that the object under study is defined not as the single system, which should be managed from a single point, but as an association of several systems, where each element of the system is independent and has its own goals, tasks and interests. In order to investigate the suitability of the method, it is tested for one service, describing this service from point of view of different actors involved. The result of the study shows that investigating the public service with SoS method can reveal new dimensions of this service and gain in-depth understanding of the impact of the service process on the parties involved and society as whole.

The paper examines the current trends in income generation of rural households in Ukraine and specifics of its relationship with social capital. The significance of the research topic stems from the need to use social capital as a factor in increasing the profitability of rural households in conditions of high deprivation poverty and low living standards in rural areas. Social capital is a resource, the capitalization of which forms the preconditions for increasing the profitability of households by converting social capital into other types of capital and minimizing transaction costs. The purpose of the study is to assess current trends in income generation of rural households in Ukraine and to define specifics of the relationship between income and social capital of villagers’ families. The study uses statistical methods, general scientific methods of analysis and synthesis, dialectics and abstract-logical methods, the method of comparison. The methods of studying the relationship between social capital and household income are based on understanding the interaction of these economic categories in development. It is established that the vast majority of rural households in Ukraine are not involved in social networks that have a high potential for income growth, and the level and structure of their income are a barrier to the formation of social capital. The income and social capital of rural UTCs are accumulated mainly by the local elite, which is the reason for the spread of fragmented social capital, which is formed on the basis of closed networks.

Machine manufacturers face the challenge that components in contact with aggressive media must fulfill extreme requirements in terms of corrosion and wear resistance. In many cases, filled polymer-based coatings provide sufficient protection. In the course of this work, such coatings were produced and tribologically tested with respect to their tribological performance from model to component-like levels. To obtain information on the occurring tribological influences with regard to used resin or particle size, rotational ball-on-disk tests were carried out. Based on these findings, the most promising coating was selected and tested using application-oriented test methods. The obtained results showed a generally good wear resistance of the coatings against metallic counterparts in lubricated states. In addition, the further development of the model tests, towards application-oriented tests, also provided the basis for the transferability of the results.
Influence of Manufacturing Tolerances on the Behavior of Pneumatic Seals using EHL Simulations
Authors: Bauer Niklas , Schmitz Katharina
Published: February 2023

The sealing friction in pneumatic spool valves is influenced by several factors, like the lubricant and sealing material properties, the topography of the contacting surfaces and the geometry. In practice, surface roughness and geometry are subject to manufacturing tolerances. This publication presents a simulative investigation on how these tolerances affect the sealing contact. For that, friction force and leakage are calculated for different bore diameters and surface roughness. An increase in bore diameter leads to an almost linear decrease in friction and an increase in expected leakage. Higher surface roughness amplitudes are predicted to increase both friction and expected leakage.
