Authors: Md Razak Mohd Razali , Kassim Zaleha , Abd Wahab Ridhwan , Hazahari Noor Yuslida
Published: March 2022

This study was conducted at horseshoe crab’s natural spawning ground in Johor Lama, Kota Tinggi, Johor, Malaysia (1°35'00"N 104°00'49"E). Six nests were excavated on 4 August 2020, four hours after the highest tide. Conditions of the spawning site were observed and recorded. Grain size analysis was conducted. Eggs hatching rate, larvae moulting rate, infection rate, and larvae abnormality rate were recorded. There are two types of reclamation observed in Johor Lama: (i) concrete wall and (ii) stack of boulders. Mangrove and muddy areas in Johor Lama are still preserved and in good condition. Sand in the horseshoe crab spawning beach in Johor Lama was coarser and poorly sorted ( : 0.09± 0.01 cm; : 1.89 ± 0.03) as compared to the one in Balok, Pahang (mid-tide mark, August 2012: : 2.38 ± 0.04 cm; : 0.86 ± 0.04). The quantity of the eggs inside each nest in Johor Lama was also in accordance with the other previous studies (first nest n: 256, second nest n: 229, third nest n: 132, fourth nest n: 123, fifth nest n: 149, sixth nest n: 134). However, the hatching rates of each sample in this population were observed to be lower than the others previously studied (31.8% – 66.1%). Two types of larvae abnormalities were reported in this study: (i) genetic impairment that changed the basic Xiphosura’s body plan and (ii) external factor that caused by the impact of the substrate or predatory action that would distort the shape of the juvenile exoskeleton. Based on the observation, the natural ecosystem in Johor Lama is still in good preservation, since it is far from urbanisation and has less deforestation. However, the future of this spawning site is still in doubt, since many ports and industrials zones are located on the opposite side of the river in Johor Bahru district that could lead to the worst water pollution.

Published: March 2022

The river sand mining activity has taken place in a sand-bed river system in Selangor, Malaysia for decades even before the legalisation was initiated in 2008. This study focuses on the determination of optimum sand extraction for low-flow and high-flow seasons. The sand replenishment rate was used as the benchmark in determining the threshold level of the extractable rate in the Langat River, Selangor system. The total sediment load was computed using Yang (1973) equation due to the high percentage of agreement between the predicted sediment load and measured sediment load. Almost 41.6% of the predicted data fall within the allowable discrepancy ratio test between the predicted value and measured value. The comparison of sand replenishment rate in high and low flow seasons proved that the river system has quicker capabilities in sand replenishment rate at the extraction point during the high-flow season compared to the latter by 83%. The quantifiable volume of the extractable sand rate is proposed specifically during low-flow months (May to September) whereby the slower replenishment rate is critical and riskier. The optimal sand mining volume during the low-flow months is calculated by reducing 10% from the total replenishment volume and the recommended optimum extraction load has been delivered by the number of 25 tons lorries for easier observation by the contractor and authority’s body. The monthly optimum extraction in Langat River during low-flow months is calculated at a minimum of 437 trucks to a maximum of 20,114 trucks per month.

Published: March 2022

Regarding the seemingly ignored corpus for pedagogical contexts, it is necessary to investigate how prospective English teachers perceive corpus and its use for language teaching. From the description of the perceptions, it is then possible to consider further pedagogical implementation. This study thus examines English Education Department students' perceptions of corpus use for English language teaching in the Indonesian context. There are 31 participants from the fifth-semester students of an English Education Department in Yogyakarta, Indonesia. The perception data were collected through questionnaires and interviews after some practice of corpus use. The questionnaires and interviews show that most students perceived corpus positively and found corpus application for language teaching beneficial and essential, albeit unfamiliar with corpus. Due to ignorance, there are some difficulties faced by the students. However, this study shows the advantages of using corpus for teaching language outweighed the challenges. Thus, it should be considered to equip students in language education departments with corpus lessons intensively.

Published: March 2022

Infections by maternally inherited bacterial endosymbionts, especially
Wolbachia, are common in insects and other invertebrates but
infection dynamics across species ranges are largely under studied.
Specifically, we lack a broad understanding of the origin of
Wolbachia infections in novel hosts and the factors governing
their spread. We used Genotype-by-Sequencing (GBS) data from previous
population genomics studies for range-wide surveys of Wolbachia
presence and genetic diversity in over 2,700 North American butterflies
of the genus Lycaeides. As few as one sequence read identified by
assembly to a Wolbachia pan-reference genome provided high
accuracy in detecting infections as determined by confirmatory PCR
tests. Using a conservative threshold of five reads, we detected
Wolbachia in all but two of the 107 sampling localities spanning
the continent, and with most localities having high infection
frequencies (mean = 91\% infection rate). Three major
lineages of Wolbachia were identified as separate strains that
appear to represent three separate invasions of Lycaeides
butterflies. Overall, we found extensive evidence for acquisition of
Wolbachia through interspecific transfer between host lineages.
Strain wLycC was confined to a single butterfly taxon, hybrid
lineages derived from it, and closely adjacent populations in other
taxa. While the other two strains were detected throughout the rest of
the continent, strain wLycB almost always co-occurred with
wLycA. Our demographic modeling suggests wLycB is a recent
invasion. These results demonstrate the utility of using resequencing
data from hosts to quantify Wolbachia genetic variation and
provide evidence of multiple colonizations of novel hosts through
hybridization between butterfly lineages and complex dynamics between
Wolbachia strains.

Mitochondria continuously undergo morphologically dynamic processes of
fusion and fission to maintain their size, shape, amount, and function;
yet the precise molecular mechanisms by which mitochondrial dynamics is
regulated remain to be fully elucidated. Here, we report a previous
unappreciated but critical role of eukaryotic elongation factor 2 (eEF2)
in regulating mitochondrial fission. eEF2, a G-protein superfamily
member encoded by EEF2 gene in human, has long been appreciated as a
promoter of the GTP-dependent translocation of the ribosome during
protein synthesis. We found unexpectedly in several types of cells that
eEF2 was not only present in the cytosol but also in the mitochondria.
Furthermore, we showed that mitochondrial length was significantly
increased when the cells were subjected to silencing of eEF2 expression,
suggesting a promotive role for eEF2 in the mitochondrial fission.
Inversely, overexpression of eEF2 decreased mitochondrial length,
suggesting an increase of mitochondrial fission. Inhibition of
mitochondrial fission caused by eEF2 depletion was accompanied by
alterations of cellular metabolism, as evidenced by a reduction of
oxygen consumption and an increase of oxidative stress in the
mitochondria. We further demonstrated that eEF2 and Drp1, a key driver
of mitochondrial fission, co-localized at the mitochondria, as evidenced
by microscopic observation, co-immunoprecipitation, and GST pulldown
assay. Deletion of the GTP binding motif of eEF2 decreased its
association with Drp1 and abrogated its effect on mitochondria fission.
Moreover, we showed that wild-type eEF2 stimulated GTPase activity of
Drp1, whereas deletion of the GTP binding site of eEF2 diminished its
stimulatory effect on GTPase activity. This work not only reveals a
previously unrecognized function of eEF2 (i.e., promoting mitochondrial
fission), but also uncovers the interaction of eEF2 with Drp1 as a novel
regulatory mechanism of the mitochondrial dynamics. Therefore, eEF2
warrants further exploration for its potential as a therapeutic target
for the mitochondria-related diseases.

Published: March 2022

It is not straightforward to urge and prepare MSMEs to participate in the standard tax system. MSMEs must have adequate tax knowledge and competence to comply with their tax obligations after they enter the standard tax system. The research aims to develop a strategy for transitioning to a normal tax system from the perspective of both the taxpayer and the government, including the barriers encountered. This study used a qualitative approach and an in-depth interview to obtain data. A review of the literature was conducted, as well as in-depth interviews with DGT officials, tax scholars, tax practitioners, and SME taxpayers. The most recent rule on final income tax for MSMEs establishes a time restriction for applying the final income tax rate and recording. The grace period was designed to teach MSMEs how to manage their bookkeeping and other obligations under the conventional tax system while growing their business. According to the study's findings, MSMEs taxpayers do not have a distinct strategy for dealing with the conventional tax system. They do, however, have commercial plans that overlap with the transition strategy. On the other hand, the government, through DGT, launched a plan called Business Development Services. The challenges of human resources and initiative affect both government and MSMEs taxpayers. This article examines the strategic procedures necessary to convert MSME taxpayers from a presumptive tax regime to the implementation of a conventional tax system, as well as the barriers encountered in achieving tax equity. The report proposes a transition strategy from a presumptive, tax regime to the implementation of a conventional tax system on the hard-to-tax sector by the Indonesian tax authorities and MSME taxpayers.

Published: March 2022

Conducting polymer nanocomposites are the forthcoming materials for developing technologies, as they possess a combination of unique properties of their components. This study used the sol-gel technique to prepare and fabricate nanocomposite of polyaniline (PANI), with nanomaterial (TiO2), doped by tin (Sn+2) (PANI/Sn+2/TiO2). Novel nanocomposites were prepared in different ratios (5%, 10%, 15%, 20%, and 25%) of weight for the nanomaterial (Sn+2/TiO2) to the polymer (PANI). The prepared nanocomposites were characterized with several techniques including Fourier transform infrared (FT-IR) Spectrometer, Ultraviolet-visible (UV-vis.) spectroscopy, X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and Atomic Force Microscopy (AFM). This research has presented the role of nanomaterial and described the easy process of their homogenous distribution in the (PANI/Sn+2/TiO2) nanocomposites. The electrical conductivity of the prepared materials was examined and confirmed by electrical conductivity. The combination of Sn+2/TiO2 in the PANI matrix will be very valuable for the improvement of the physical and chemical properties of the polymer's conductivity.

Bystander intervention in potential sexual assault situations is a common method of helping to address sexual violence on college campuses. Although numerous variables have been shown to mediate bystander intervention behavior, the pool of potential correlates is limited. The present study used regression analysis to determine the relationship between bystander behavior and three predictors: religiosity, gratitude, and victim empathy. Consistent with prior research, both religiosity and gratitude significantly predicted bystander behavior. Contrary to prior research, the relationship between victim empathy and bystander behavior was negative. Findings are discussed relating to potential bystander intervention programs, and future research, particularly on gratitude, is suggested.
An Assessment on Water Quality (TDS, EC, ORP, and PH) of Selected Boreholes in Baraton Centre
Authors: A Baraka
Published: March 2022

Drinking water is a very essential part of every living being. Due to shortage of tap water for many households in Kenya, Borehole has become one of the main sources of water, which offers support to human health, diversity in the ecosystem and economic growth. Water quality is essential for policy formulation affecting health. This is due to the fact that, ground water resources are commonly vulnerable to pollution which degrades their quality. Some of the toxicological effect that have been reported of drinking polluted water include cancer, genetic aberrations among other ailments due to borehole minerals and metals. In this study, borehole water quality analysis involved determining the levels of Total dissolved solids (TDS), Electrical conductivity (EC), Oxidation-Reduction potential, and pH to aid in monitoring borehole water data. This was compared against the standards set by W.H.O, who have created water quality guidelines which provides a Limit Value for each parameter for drinking water. It is crucial that a continuous monitoring of water quality is done at regular periods due to global changes in population, increased pollution and use of river waters resulting in the consumption of contaminated drinking water. Many people suffer from varied water borne diseases hence the great interest in having details about various physico-chemical parameters such TDS, EC, ORP, salinity and pH determined. The samples collected were analyzed. The average PH was 5.25 which is not fit to be consumed thus posing a risk to humanity. The electrical conductivity was averagely 113µS/cm. The TDS level was averagely 56.5 ppm. The average ORP was 376.8 mV. There was a variation in the samples collected depending with the season. By use of standard analytical methods, the research investigated the variation of pH, EC, ORP, TDS and salinity which is a good indicator of water quality. WHO has asserted that, the safest water should be of lower conductivity of 200 to 800 µS/cm, ORP of -50 millivolts, TDS of 300 parts per million (ppm) and pH of 6.5-8.5. The study has thus compared the levels against the above standards and also presented the correlation between the parameters in addition to showing the seasonal variations of the above physical –chemical parameters.

Kuliah Kerja Nyata adalah bentuk kegiatan mahasiswa yang memberikan ilmu dari pengalaman belajar yang didapat kepada masyarakat di luar lingkungan kampus. Walaupun di tengah wabah pandemi covid-19, mahasiswa masih tetap bisa melakukan Kuliah Kerja Nyata (KKN) secara online untuk menghasilkan riset dalam bentuk laporan yang didapat dari beberapa sumber tulisan guna memberikan masyarakat pengetahuan tentang akan kemajuan teknologi di bidang informasi dan komunikasi. Kemajuan teknologi informasi dan komunikasi kini bisa merambah ke bidang apapun termasuk merambah ke sektor bisnis. Dengan kemajuan teknologi informasi dan komunikasi, masyarakat desa yang kebanyakan bermata pencaharian sebagai petani dapat menggunakan kemajuan teknologi informasi dan komunikasi untuk membantu menjual produk hasil pertaniannya secara luas tidak hanya di pasar lokal saja, melainkan dapat dipasarkan hingga luar daerah bahkan dapat diekspor ke luar negeri. Dengan riset yang dihasilkan oleh mahasiswa akan kemajuan teknologi informasi dan komunikasi di sektor penjualan atau bisnis, diharapkan masyarakat dapat diberikan ide dan inovasi dalam memperluas pemasaran hasil pertaniannya. Walaupun ada masyarakat yang sudah familiar dengan kemajuan teknologi informasi di bidang penjualan atau bisnis ini, namun diharapkan hasil riset mahasiswa yang dituangkan dalam bentuk laporan, e-book, dan buku saku ini dapat lebih membantu atau memberikan inspirasi kepada masyarakat tentang aplikasi apa saja yang dapat digunakan untuk membantu memperluas pemasaran produk pertaniannya secara mudah dan bahkan gratis.

IMPROVING PAYAKUMBUH ELEMENTARY TEACHERS' ABILITY IN DESIGNING MATHEMATICAL HIGHER ORDER THINKING SKILLS PROBLEMS
Authors: Tasman Fridgo
Published: March 2022

The 2015 PISA (Program for international students assessment) results put Indonesia in 65th position out of 72 countries. The results show that the mathematical abilities of Indonesian students are still very low. These low abilities include. : (1) understanding complex information; (2) theory, analysis and problem solving; (3) use of tools, procedures and problem solving; and (4) conducting an investigation. These four abilities are known as high-order thinking skills (HOTS). Similar conditions are also found in the city of Payakumbuh. Based on interviews with several elementary school teachers from Payakumbuh it was revealed that students were not used to solving problems that demanded HOTS because in general teachers are also not trained to design mathematical problems with high cognitive levels. They tend to give questions at low level. As a result, this is not developing students' mathematical abilities. Based on this, a community partnership program was implemented with the aim of increasing the ability of elementary school teachers to design questions to assess HOTS. The activity partners were high school elementary school teachers in Groups 1 and 3 of Payakumbuh, which numbered 55 people. Activities are packaged in the form of a combination of workshops and implementation in schools. In the workshop, the teachers were given knowledge and skills in designing HOTS questions by the resource person. Next, the teachers in groups designed HOTS questions. The questions that have been designed by the teacher are validated together, then tested to students in grades IV, V, and VI. Based on the collected data, it is known that there was an increase in the ability of high-class teachers in Elementary Groups 1 and 3 of Payakumbuh in solving HOTS questions. The ability of the teachers to design HOTS questions also increased, although some of the questions that were designed were still slightly above the application (few still want high analysis, evaluating, or creating).
