Published: August 2021

Addressable flat-panel x-ray source has important applications in next-generation low-dose x-ray imaging technology. In this study, a fully vacuum-sealed addressable flat-panel x-ray source has been fabricated using a ZnO nanowire cold cathode. The x-ray source was formed by assembling gated ZnO nanowire field emitters and a molybdenum thin film transmission anode target. Pulsed and addressable x-ray emission was achieved by applying voltages to the extraction gate. Radiation dose rates of 235 nGy/s were achieved when the device was operated at 21 kV anode voltage and 140 V gate voltage. Projection x-ray images of objects were obtained by the flat-panel x-ray source. Our results demonstrated the feasibility of a fully addressable cold cathode flat-panel x-ray source.

Significance

Prostate infections and inflammation are potential initiating factors in prostate cancer development. Here, we investigated whether bacterial infections are associated with the presence of the most common prostate cancer oncogenic gene fusion, TMPRSS2:ERG, in early precursor lesions. We provide evidence that TMPRSS2:ERG (ERG+) gene fusions can initiate in early prostate cancer risk factor lesions, including proliferative inflammatory atrophy in the setting of prostate infection. We further demonstrate that these infection-associated ERG+ precursor lesions are transitioning to early invasive cancer. Overall, we provide evidence that, in at least a subset of cases, infection-induced TMPRSS2:ERG gene fusions are an early alteration in the carcinogenic process.

Published: August 2021

Significance

During the COVID-19 pandemic, individuals have been forced to balance conflicting needs: stay-at-home guidelines mitigate the spread of the disease but often at the expense of people’s mental health and economic stability. To balance these needs, individuals should be mindful of actual local virus transmission risk. We found that although pandemic-related risk perception was likely inaccurate, perceived risk closely predicted compliance with public health guidelines. Realigning perceived and actual risk is crucial for combating pandemic fatigue and slowing the spread of disease. Therefore, we developed a fast and effective intervention to realign perceived risk with actual risk. Our intervention improved perceived risk and reduced willingness to engage in risky activities, both immediately and after a 1- to 3-wk delay.
Creative constructs, constructions, and frames in Internet discourse
Authors: Vandelanotte Lieven
Published: August 2021

This paper explores questions of constructionality and framing in Internet discourse. It proposes a sharper understanding of what, as analysts, we mean by Internet memes, before turning to formal and semantic aspects of Internet memes as multimodal (image-text) constructions. A broad range of examples is considered, but the focus is mainly on image macro memes and labelling memes. Particular attention is focused on the presentational templates that mark out particular meme constructions, and grounds for distinctions between creative constructs and entrenched, conventionalized constructions are offered. The role of frames in the meaning-making mechanisms of memes is investigated, and also explored for a type of Twitter discourse not usually considered alongside established Internet memes.
Grammar change
Authors: Haider Hubert
Published: August 2021

Structurally, cognitive and biological evolution are highly similar. Random variation and constant but blind selection drive evolution within biology as well as within cognition. However, evolution of cognitive programs, and in particular of grammar systems, is not a subclass of biological evolution but a domain of its own. The abstract evolutionary principles, however, are akin in cognitive and biological evolution. In other words, insights gained in the biological domain can be cautiously applied to the cognitive domain. This paper claims that the cognitively encapsulated, i.e. consciously inaccessible, aspects of grammars as cognitively represented systems, that is, the procedural and structural parts of grammars, are subject to, and results of, Darwinian evolution, applying to a domain-specific cognitive program. Other, consciously accessible aspects of language do not fall under Darwinian evolutionary principles, but are mostly instances of social changes.
Variation in language use is different from variation in genes
Authors: Sansò Andrea
Published: August 2021

This commentary discusses some aspects of Haider’s model of grammar change that are problematic from the
perspective of usage-based approaches to language change. These aspects include (i) the postulated equivalence between
intentionality and teleology, (ii) the metaphorical nature of Darwinism when applied to other domains, and (iii) the nature of
explanations of language change. With respect to (i), it is argued that equating intentionality with teleology disregards the fact
that innovation in grammar is not unprincipled like in genes. With respect to (ii), the question is whether a comparison between
as different concepts as human behaviors/brains and genes/populations can be considered as more than a metaphor (however
powerful). Finally, with respect to (iii), a number of diachronic-typological studies are discussed that concur to suggest that
variation in speakers’ verbal productions is largely adaptive, and therefore selection operates on a skewed pool of variants in
which non-adaptive/dysfunctional variants are a minority (if any).

Authors: Meilani  , Nugroho Soebandrija Khristian Edi , Wijaksono Sigit
Published: August 2021

The main goal of this study is to analyze the correlation between the detonation source and the time duration of blast loading and the plate’s dynamic response with the variation of peak pressures. The plate was modeled as a concrete orthotropic plate with semi rigid support at all its sides. Natural frequency can be found with Modified Bolotin Method and the numerical calculation is solved with Mathematica and Microsoft Excel. The results show that the longer the explosion distance, the maximum pressure due to the explosion is smaller and the time that the blast wave needed to reach the plate’s surface will become longer. When the peak pressure of blast loading become bigger, the plate’s dynamic response and deflection will become bigger.

Published: August 2021

As the growth in geotechnical science, there are a lot of new innovations that are used for solving geotechnical problems. One of those innovations is geotextile.This geotextile is often used in earth fill as reinforcement with function to increase the shear strength of existing fill and related with the interaction between geotextile and fill material. Based on this fact, this research is conducted to know the interaction of soil type to geotextile. The result of the research shows that all of the tested soil shear strength parameter comparison are below 1 (0.23; 0.29; 0.24 for C of clay comparison), (0.65; 0.77; 0.98 for ϕ of clay comparison), (0.53; 0.66; 0.67 for ϕ of sand comparison), and (0.53; 0.66; 0.67 for ϕ of coarse aggregate comparison). So it could be concluded that the shear strength of fill material and geotextile material is lower than the shear strength of fill material without geotextile.

Published: August 2021

Study of damage index of Eccentrically Braced Frame-Vertical Shear Link (V-EBF) was performed. The study was part of the research of damage index of several types of seismic resistance of steel structure. Three different stories of the V-EBF were taken from the preceding experimental study conducted by other researchers. Monotonic and semi-cyclic pushover analysis was carried out by using OpenSees software to get the parameters needed to determine the damage index which was calculated according to Park Ang’s theory. The index is measured as a sum of deformation per-cycle and the energy absorption. The study found that the natural frequency of the structure decrease with the increasing of structural damage. The reduction of natural frequency from the initial condition to the third damage is 70.79%, 71.68%, and 62.13% of the one, two and three stories of The V-EBF structure, respectively. The study observed the critical limit where the damage index begins to increase drastically, followed by a decrease of the natural frequency. It occurred when the ratio of natural frequency to the initial frequency was in the range of 43% to 59%.

Authors: Berawi Mohammed Ali , Calista Miranda , Gunawan
Published: August 2021

Transit-Oriented Development (TOD) is a city concept that encourages public transport usage (transit). However, the development of the TOD in Jakarta is currently still focused on the development of residential buildings near the station. It causes a shift in the essence of TOD to TAD, Transit Adjacent Development, an area that is close to transit stations but does not trigger transit activities. Mixed land use is essential in the TOD area because the diversity of building functions will affect the transit activities of the community. To maximize the function of TOD, ridership information for each building function is needed to determine transportation mode selection. This study reviews residential and office buildings, while trains, buses, and private vehicles are transportation modes reviewed, to obtain ridership value that is expected to affect TOD area planning. Questionnaire surveys is performed as a data collection technique to acquire information that will be mathematically processed. The result shows that the mode split value of residential buildings is 47.1% for trains, 11.8% for buses, and 41.2% for private vehicles, while mode split value of office buildings for trains, buses, and private vehicles are 43.8%, 18.8%, and 37.5%, respectively. It indicates that train is the public transportation mode widely used by the users of residential and office buildings located in a 0-800 meters from transit stations.

Simple Span Bridge Loading Based on Weight in Motion Data
Authors: Suangga M. , Mahathir
Published: August 2021

Over Dimension Over Load (ODOL) vehicle is claimed to be the cause of a number of fatal accidents and damage to road infrastructure in Indonesia and has become a serious issue for roads and bridges maintenance. Over loaded vehicles can result in damage to the bridge, reduced bridge capacity and can even result in collapse of the bridge. Therefore the characteristics of the actual vehicle load need to be known and compared to the bridge design load according to the bridge design code and standard. In this paper, an analysis is carried out on the actual traffic load data obtained from the measurement results using Weight in Motion (WIM) in Kaligawe, Semarang, Indonesia. Monte Carlo simulation is used to simulate the arrival of the vehicle. The results of vehicle load simulation are then applied to a simple span bridge with a span of 30, 40, 50 m. The bending moment and shear force obtained due to actual load compared to the magnitude of the bending moment and shear by applying Indonesia Bridge Loading Standard. The results show that 43 percent of vehicles are overloaded. The bending moment and shear force caused by actual load is less than the design bending moment and shear force for 30 m, 40 m and 50 m bridge span.

Published: August 2021

Indonesia experiences floods which are rarely well documented in map form. Monitoring and estimating the impact of floods at almost the same time involves using a variety of techniques, from digital maps to using detailed surveys or remote sensing techniques. However, when using remote sensing techniques, the results depend on the data acquisition time (day or night) as well as by weather conditions. However, this obstacle can be overcome by using radar satellite imagery. The purpose of this study is to describe the surface of the water bodies affected by flooding in the Cidanau-Ciujung-Cidurian River Basin from 2016 to 2020. For this case study, the Sentinel-1 SAR Band data obtained from the ESA (European Space Agency) were used as research data. Data sets are retrieved before, during or after a flood and processed using SNAP Desktop. The result will display flood conditions using RGB color as a sign between wet areas (inundated) and dry areas (not inundated).

Authors: Puspitasari Nia Budi , Glennardo Paskalis
Published: August 2021

The construction industry has always been the biggest contributor to environmental damage. With the emergence of Leadership in Energy and Environmental Design (LEED) certification and Mayor Regulation Number 24 of 2019 concerning green buildings and Presidential Regulation in Indonesia concerning the importance of green industry products in the procurement process led to the emergence of urgency for the construction sector to create a focus on green. One focus that needs to be considered because contributing a large role in the construction process from beginning to end is the procurement process. The problem that occurs is that there is no awareness from Project Manager in Central Java is regarding environmental aspects in making procurement specifications. This is evident because the consideration of certification of Environmental Impact Assessment, and Occupational Health and Safety Regulation has not yet been taken into consideration in the specification of Project Manager considerations. As a result, government buildings have 46% lower energy efficiency compared to private buildings. With the DEMATEL method, it was found that the criteria “lowest bid value”, “Reducing the use of hazardous materials”, “Minimizing energy consumption”, “Minimizing energy loss”, “Clarifying environmentally friendly fuels”, “Impact on the environment during and after construction”, “Work procedures”; “Supervision”, and “Frequency of failure” is a criterion that is considered to influence other criteria is greater and can be an urgency for the government of Central Java.

Authors: Oktarina Rienna
Published: August 2021

The earthquakes can cause serious the disruption to the functioning of a community, and can cause physical damage, including damage to houses and the environment. The number of damaged houses by the earthquake needs to be predicted well, so the disaster management activities can be carried out properly as well. This research performs calculations to predict the number of damaged houses by the earthquake, using RADIUS. The results obtained from the prediction model in this study still provide a high error value, which is 71.9%. This means that the output of the prediction model in this research is not accurate enough to predict the number of damaged houses by the earthquake in Indonesia. However, the prediction model in this research is presented in a mathematical model and has clearly shown the relationship between the input and output variables. So that it is easy to understand and can be developed in further research more easily. The prediction model for the number of damaged houses in this research then can be developed into an estimation model for the relief items needed by the internally displaced persons (IDPs). After predicting the number of damaged houses, the process of estimating the number of IDPs then can be carried out, if the estimated number of IDPs is known, then an estimate of the relief items needed by the IDPs can be calculated well.

Published: August 2021

The present paper deals with the research about bacterial decontamination by using non thermal argon plasma jet and exploring the argon plasma jet application study for non thermal raw milk processing. Escherichia coli and Staphylococcus aureus bacterias were chosen in this research to be treated by argon plasma jet system, due to those types of bacterias are usually contained in raw milk. The bacteria that have been cultured in agar media was irradiated by argon plasma jet at various plasma treatment time to understand the effect of the jet on the bacteria growth. It was found that the growth of bacteria was inhibited proportionally with the plasma treatment time in their appropriate agar media. This was clarified by the increasing of inhibition zone diameter of bacteria’s growth in petri dish. From this result, attempting the application of the developed plasma system for raw milk processing by adopting the system to generate plasma under liquid milk. Argon plasma discharge inside the milk solution can be generated by applying 1.5 kVp-p electrical AC power and the operation temperature could be constantly kept under 32°C even after 15 min underwater plasma treatment to confirm non thermal processing. Investigating the effect of plasma treatment time on non thermal raw milk processing has been done, however all the results show the achievement still less comparable with the conventional raw milk processing, thermal pasteurisation.

Published: August 2021

Convolutional neural networks (ConvNet or CNN) are deep learning algorithms that can process input images, assign meaning to various aspects or objects in the image (biases and learnable weight) and recognize one image from another. The bigger kernel size will take more time to process the input.We present a novelty way to use a 4D rank tensor to improve a convolutional process. At the early stage of the Convolve4D development, the edge detection with 3×3 kernel and The Laplacian of Gaussian (LoG) with 5×5 kernel size was used to demonstrate the convolutional process improvement. The Convolve4D needs more elaboration to be used into a CNN algorithm. The advantage of convolve4D is only need 9 loops to calculate 81 outputs, whereas convolve2D need 9 × 9 × 3 × 1 × 7 × 7 = 11.907 loops. The result is 18.5% shorter when using a 5×5 kernel; it reduces from 0.54 seconds to 0.44 seconds for the edge detection convolution process.

Published: August 2021

Indonesia is a country with a tropical climate so that fruit and vegetable plants can grow easily in Indonesia.Fruits have many good nutrients such as vitamins, proteins and others. But the fruit also has a period where the fruit is said to be fresh fruit.During this time there are still many fruit supplier companies that send fruit unfit for consumption due to lack of accuracy in the process of sorting the fruit when the fruit is taken from the plantation and the entry of other fruit into an improper packaging. Thus, it makes detecting food spoilage from the production stage to consumption is very important. We propose a design of computer vision-based technique usingdeep learning with the Convolutional Neural Network (CNN) model to detect fruit freshness. The specially designed CNN model is then evaluated with public datasets of fruits fresh and rotten for classification derived from Kaggle.

Published: August 2021

Portable healthcare solution to detect fall is needed for special care people and elderly, especially if they want to live independently. If this solution needs special made device by the factory, it requires huge electric consumption, lots of materials, and can contribute to the environmental pollution. Smartphone is one of the most promising device to be used as fall detection because it has lot of potentials: easy to find, compact, has sensors, and can even be accepted by elderly. There are two main approaches in fall detection: threshold-based method and model-based: pattern recognition method. Threshold-based usually been used in real life because it can be developed quite quickly and use minimal computation process to provide movement classification result (fall or non-fall). Model-based: pattern recognition method (using machine learning) has relatively better accuracy result but requires a long training time, a lot of resources to process, and more difficult to be developed. The researchers present the comparison results of threshold-based and model-based: pattern recognition; and optimizing the model in machine learning so the model has the prospect to be implemented in applications to support green computing.

Authors: Rahutomo Reza , Pardamean Bens
Published: August 2021

Jakarta lifted up lockdown after passing more than 50 days of large-scale social activity restriction and initiated phase opening to new normal. To analyse Jakarta’s air quality after passing lockdown, a pipeline of data engineering is needed. By acquiring time series data from openaq.com, a time-series database system is developed with Python programming language and its fundamental libraries namely Pandas, NumPy, SQLite. After PM 2.5 data are pre-processed into average per-hour and grouped by applicable periods (pre-lockdown, lockdown, and phase opening), a pattern of PM 2.5 in South Jakarta is revealed by using data visualization library Matplotlib. The apex of PM 2.5 occurs earlier during lockdown (04:00) and phase opening (02:00) rather than when it was normal or pre-lockdown (08:00) even though the nadir of PM2.5 still occurs at the same time (16:00 – 17:00).

The increasing positive cases of Covid-19 have quite significant impact on the Indonesia economy especially for Small and Medium Enterprises (SME’s). The Indonesian government is preparing a way to live side by side with the COVID-19 outbreak through less contact activity (LCA). Regarding the thematic efforts for economic recovery after the implementation of the new normal protocol, the adaptation process in people’s economic activities known as the Less Contact Economy (LCE) which can be interpreted as economic activity without contact, but by using digital communication equipment. This model of economic activity, which is strongly influenced by current technological trends, will certainly be the future of the world economy, as part of the 4.0 industrial revolution. For example: mobile apps based on e-commerce. Based on design thinking process, this paper proposes a practical interface design for mobile apps design. In this research, the researcher designing Graphical User Interface (GUI) for mobile apps based on e-commerce “Tuku Sayur” to marketing and distribute agriculture products during pandemic. GUI is one of the most important issues in development of mobile apps. The major problem in the interface design mostly caused by unique feature of mobile device. This is quite challenging for designer how to present clear user interface on a limited screen without overload. The Semantic Differential method was used to understand the impression captured by respondents on the GUI design of Tuku Sayur application. This research is very important to help farmers to marketing and distributing agriculture products through mobile apps. Hopefully, this research can be used as a reference to published mobile apps to support less contact economy in order to makes the economy relatively productive during the pandemic.

Asset is valuable properties belonging to company. To support daily activities, usually companies lend their assets to the employees. Lending and borrowing assets can be problematic if the company does not have good asset management tool. We studied one of the ISP company in Jakarta that need help to create asset management tool for their daily activities. Human error and untraceable historical data were the main problems of the company’s old system. The objective of this project is to help providing solution by designing a prototype system of an asset management tool, especially for lending process to the employees. The system is using RFID-card, barcode, camera, and web-based client server architecture. By using this architecture, the asset lending process can save both paper and time consuming for borrowing process. After going through several stages of an experiment and data collection, it can be concluded that this design succeeded in helping the asset lending process to be better, which can be proven by the results of user satisfactory surveys that have been done

Turmeric, tamarind, and ginger are widely used as ingredients of Indonesian traditional beverage known as jamu. This latter is known for its beneficial properties for human health, such as high antioxidant capacity, which make it potential to be developed as functional beverage. This study aimed at optimizing functional beverage formula made from turmeric, tamarind and ginger with regard to antioxidant capacity and sensory qualities using D-optimal mixture design. It was revealed that the optimum formula was the mixture containing 5.0%(v/v) turmeric extract, 9.9%(v/v) tamarind extract, 15.1%(v/v) ginger extract, 40%(v/v) sugar solution, and 30%(v/v) water. Such a formula exhibited an antioxidant capacity of (0.184 ± 0.002) mgAEq/mL and an overall hedonic score of 4.27 (out of 7).
