Authors: Jumabay Uldanay , Nevskaya Irina , Tazhibayeva Saule 
Published: November 2022

Abstract
Many languages distinguish numeral classifiers in their grammar systems categorizing nominals in terms of their inherent nature, such as animacy, shape, form, and arrangement. Kazakh, a Turkic language of Central Asia, distinguishes numeral classifiers, which are used in numeral classifier constructions consisting of a numeral, a numeral classifier and a specified noun. Numeral classifiers in such constructions can be optional. This paper aims at a preliminary description of the features, types, and usage of numeral classifiers in Kazakh.
What does image schema facilitate in English L2 vocabulary processing?
Authors: Sato Takeshi , Ogura Masa’aki , Burden Tyler 
Published: November 2022

AbstractThis study aims to examine the effectiveness of image-schema-oriented visual aids to cohesively process the semantic information of English (L2) phrasal verbs (PVs), leading to the proper understanding of their senses. As previous studies suggested the advantage of image-schema-based L2 vocabulary learning, our study hypothesizes that image-schema-oriented visual aids in a multimedia environment can develop the motivated semantic networks of L2 PVs, leading to their successful processing and comprehension. To verify the hypothesis, we administered two empirical studies to Japanese undergraduates learning with image-schema-oriented visual aids. Although they were administered in different settings, both studies showed that the participants could obtain significant learning gains, especially figurative meanings. This finding suggests that the use of image-schema-oriented aids could successfully process semantic information of L2 PVs enough to develop a motivated semantic network and reconfirm the significance of image schema in terms of enhancing learners’ metaphoric competence.

Abstract
Titanium dioxide (TiO2) is an attractive semiconductor oxide compound due to its good stability properties both in chemical and photochemical. TiO2 in the form of nanofibers offers many advantages such as high surface area, flexibility of structures and mechanical properties such as stiffness and tensile strength. In this study, we reported the synthesis of TiO2 nanofibers using electrospinning technique. TiO2 nanofibers were produced from titanium (IV) iso-propoxide precursor solution at different applied voltages of 10 kV and 12 kV, while the flowrate was kept constant at 0.7 ml/hours during the process. The electrospinning process produced a thin layer of nanofibers which was then calcined for 1 hour at different calcination temperature. Based on the SEM images, we found that at applied voltage of 12 kV uniform and continuous nanofibers had already formed with the average diameter of nanofibers was in the order of sub microns. The diffraction pattern of TiO2 nanofibers shows that at a calcination temperature of 450°C, the phase was dominated by the anatase phase, while at 500°C it has a combination of anatase and rutile phases. Based on UV-Vis spectroscopy, it was found that the energy gap of TiO2 nanofibers calcined at temperature of 450°C and 500°C were 3.32 eV and 3.22 eV, respectively.

Abstract
The vertical cylinder tank can serve as a measuring tool and as a storage device. When the vertical cylinder tank is used as a measuring instrument, it needs to be calibrated. In this process, measuring the diameter of the vertical cylinder tank is the most important step. The diameter of the tank is divided into several parts, the first part is referred to as a reference, where the results of the reference measurement will be used in the measurement of other parts. To conduct this measurement, a prototype consisting of two sensors, namely, laser distance and rotary encoder, is build. The prototype was tested using five variations in standard tube diameters measured using a steel ruler. The results of this test produce an average correction of +0.17 mm with an error of 0.59%. Furthermore, the prototype is used to measure the diameter of the vertical cylinder tank, which is compared with the certificate of the results of tank measurements using a theodolite. Testing the prototype with a vertical cylindrical tank produces a correction of +8.73 mm with an error of 0.03%. This error value is within the error limit according to the OIML International Recommendation of R-071 for vertical tanks.

Abstract
Bantimurung is located in the early tertiary isolated small land area in Sulawesi, and this is the factor that caused the endemism of its flora and fauna. Pothos tener Wall is an excellent aquatic plant used as a bioindicator in rain tropical forests and its lives under the Bantimurung waterfalls. Aquatic plant biodiversity has a great potential for bringing about new pharmaceutical inventions derived from freshwater aquatic flora. The genus Pothos is quite popular as a medicinal plant in India and Srilanka similarly P. scandens and P.chinensis as an anti-inflammatory, anticancer, cytotoxic potential, anti-oxidant, antibacterial, anthelmintic potential, antipyretic, anti-diabetic, and bronchodilator. However, the research regarding P.tenner is quite lacking. The study aimed to analyze the antioxidant activity from three extracts (methanol, ethyl acetate, and n-hexane) of P.tenner as an endemic plant from Indonesia. The TLC chromatogram pattern of three extracts had identified the free radical scavenging after being sprayed with a 0,2% DPPH spraying agent. The DPPH method with minor modification was adopted in three extracts of P.tener to examine the antioxidant activity. The IC50 value of quercetin (standard), n-hexane, ethyl acetate, and methanol extracts were 7.4 ppm, 156,26 ppm, 196,25 ppm, and 163,78 ppm, respectively. In general, the potential antioxidant activity of three extracts was n-hexane>methanol>ethyl acetate. To conclude, the n-hexane extract of P.tener has the strongest antioxidant activity among others.

Published: November 2022

Abstract
Since pandemic mask mandates are being applied with numerous equipment to protect the wearer from exposure to viruses which become the main reason why medical masks are preferred. The increase of medical mask waste and its poor management in most countries raises concerns about microplastics in the environment. On the other hand, the usage of medical masks delivers drastic waste that is harmful to the environment in the long run. Through this research, we transform medical mask waste into polypropylene microparticles which are applicable in numerous fields. The process includes pre-treatment, creating the polypropylene solvent, freeze-drying, and characterization. There is no eloquent difference for each concentration, but the higher the polypropylene percentage, the intensity of -OH and - NH2 decreased. The XRD (X-Ray Diffraction) pattern for 6% polypropylene microparticles is slightly higher than the 15% though the peak shows at the same 2θ. Morphology of polypropylene microparticles visualized by SEM (Scanning Electron Microscope). The material has a perfectly spherical shape indicating the removal of xylene is perfectly done.

Abstract
The development of Science and Techno Park (STP) is one of the government’s efforts to increase competitiveness in the science and technology sectors as well as to improve the regional and national economy. Relevant to this, the government has planned the development of the herbal and horticultural sectors known as the Science and Techno Park of Herbal and Horticultural (STPH2). It is located in Pollung, North Sumatera Province, specifically in the Forest for Specific Purpose (KHDTK). In line with the government’s program to reduce greenhouse gas (GHG) emissions, the planning of the STP development has used the principle of Low Carbon Development (LCD) as it will bring many benefits from reducing carbon emissions which also supports sustainable regional development programs. This research was carried out by reviewing the STPH2 planning documents, such as the master plan and Detailed Engineering Design (DED), which was followed by identifying components that could reduce carbon emissions and absorb carbon emissions. The results of these findings are then compared with references. The conclusion shows that the planned components, such as building design, land cover, and water and waste management systems have followed the LCD principle.

Published: November 2022

Abstract
Environmental management program performance ratings for companies (PROPER) is a public disclosure program for environmental compliance by the Indonesian Ministry of Environment and Forestry (KLHK). PROPER is a type of government policy to enhance the business’ environmental management performance by the law’s requirements. Furthermore, PROPER is an example of how environmental management has become more open and democratic in Indonesia. The application of this instrument is an effort by the KLHK to implement some of the virtues of good governance — transparency, equity, responsibility, and community participation — in environmental management. In 2021, the PROPER Program expanded its activities’ scope by including elements of LCA implementation in the program report. This paper aims to provide recommendations for the PROPER program implementation concerning applying the ISO 14025 standard. The method used in this study are literature studies of related regulations and mapping the existing conditions against the conformity of the ISO 14025 standard. The study shows that the current PROPER program has met several requirements of the ISO 14025, comprising life cycle assessments and environmental product declarations. However, the existing program should have determined that PCR is one of the elements required to assess environmental management performance ratings.

Abstract
Passenger train products labelled as environmentally friendly now tend to be a requirement in world trade. Life Cycle Assessment (LCA) is a method for quantifying environmental performance using the Product Category Rules (PCR) document as a guideline referring to the ISO 14027 standard. This study aimed to determine the methodological requirements for the PCR draft for the Indonesian Rail-Vehicle Industry by comparing and analysing the Environmental Product Declarations (EPD) of three different rail vehicles. They were train A (from Europe) and train B and C (from non-Europe), which already had the type III ecolabel predicates, and published an EPD report referring to the PCR 2009:05 - Rolling Stock document. The result showed that each type of train had different energy consumption and environmental performance characteristics. It depends on the energy source, the weight of the material, passenger loading, and the train design speed. Train A has a carbon emission value of 0.763 grams, while trains B and C are 8.19 grams and 12.8 grams per passenger-km, respectively. The analysis of the carbon emissions in those three trains will be used as input to develop the Indonesian version of the Rail Vehicle PCR document.

Published: November 2022

Abstract
The power sector in Indonesia has a significant chance to contribute to the accomplishment of the national emission mitigation target towards NZE (Net Zero emissions) in 2060. In this study, a quantitative evaluation was used to explore and analyze the effectiveness of mitigation efforts toward energy saving potential and GHG emission reduction, as well as the cost-effectiveness of mitigation actions based on the AIM/end-use model. The RUPTL mitigation efforts (CM1 & CM2) contribute 40% (CM1) and 46% (CM2) of the energy sector’s First NDC GHG emission reduction target. Through CM3, the power sector will peak GHG emissions in 2035. This will lead to carbon neutrality by 2060. The considerable reduction in GHG emissions is affected by new and renewable development, low carbon technologies, coal phase-out, and the integration of CCS technology with an additional investment cost of 1810 billion USD or 48 million USD/year (2022-2060). Deep decarbonization in CM3 could enable the power sector avoid carbon taxes and gain revenue $2.2 billion in 2060 from carbon trading.

Published: November 2022

Abstract
An increase in population is one of the common trends in urban areas. An increase in population will affect the development of the city due to the increasing need for urban facilities and infrastructure. The number of activities and developments produced by the city also produces a large amount of energy. Part of this considerable energy is lost in the form of accumulated heat due to being trapped by urban structures. The energy lost in the form of heat accumulates as the emission level which produces heat in the form of CO2 and heat absorption in the urban materials. The Thamrin City area is one of the important trades and service areas in Jakarta which has a high level of activities. The purpose of this study is to see the urban configuration in the Thamrin City. This study uses quantitative methodology. The result is identification of several components, namely urban heat island, urban canyon, and urban energy balance in Thamrin City which affect the increase of heat temperature in urban areas and induce climate change.
