Authors: Jabeen Khajista , Naeem Zara , Iqbal Sumera , Saeed Muhammad Khalid
Published: December 2021

Ochratoxigenic fungal species are a major cause of various infections in plants and posed a serious threat to their consumers,including humans and animals. In the current study the objective was to examine the in vitro efficacy of different concentrations of leaves methanolic extract of S. helepense L. (Pers.) against target pathogenic ochratoxin producing fungal species (Trichoderma viride Pers., Trichoderma harzianum Rifai. and Cladosporium cladosporioides (Fresen.) G.A. de Vries).For this purpose, different concentrations viz. 2%, 4%, 6%, 8% and 10% of leaf methanolic extract were prepared and tested for antifungal potential in a completely randomized design (CRD). Results revealed that all the applied concentrations of S. helepense inhibited the growth of all the tested fungal strain. Maximum growth inhibition was observed in 2% of concentration of methanolic extract of S. helepense in case of C. cladosporoides i.e. 84%. On the other hand minimum reduction was observed in 4% of concentration of methanolic extract of S. helepense against T. viride as compared to control. The phytochemical analysis was also conducted to evaluate that which chemical entities were present that account for antifungal potency of methanolic extract of S. helepense. Results of phytochemical analysis revealed the occurrence of saponins, alkaloids, coumarins, flavonoids and tannins while the plant is devoid of terpenoids, phlobatanins and glycosides respectively. Hence it can be concluded that the methanolic leaf extract of the tested plant proved to be beneficial for inhibiting the growth of test ochratoxigenic fungi.

Published: December 2021

Vigna mungo L. (black gram) is a summer pulse crop endemic to Central Asia. It is one of Pakistan's top five premium food beans and a highly cost-effective crop. Allelochemicals in Trianthema portulacastrum leaf extract effect and inhibit black gram germination rate, seedling length, fresh and dry biomass of seedling from low to high concentrations. The research revealed that in vitro leaf extract of black pigweed decrease the mash bean leaf germination percentage (34% to 6%), seedling length (10cm to 3cm), fresh biomass of seedling (2.4g to 0.94g), dry biomass (1.2g to 0.47g). Biological tool Pseudomonas (PF- 097) act as bioherbicide and as plant growth promoter agent (PGPR) to decrease the Trianthema portulacastrum allelopathic stress and to enhance the growth of black gram. The Pseudomonas (PF-097) PGPR addition in vitro experiment increased mash bean leaf germination (8-42%), seedling length (12-54%), and fresh biomass of seedling (8-17%) and dry biomass of seedling (0.47g-1.2g). In vivo experimental study revealed that whole plant material of black pigweed significantly suppress the shoot length (46cm to 18cm), shoot fresh biomass (2.6g to 0.66g) and shoot dry biomass (1.31g to 0.33g) and Pseudomonas (PF-097) PGPR incorporation in vivo experminet significantly increased the shoot length (4% to 12%), shoot fresh biomass (18% to 35%), shoot dry biomass (17% to 35%).  Physiological activity of Catalase and peroxidase considerably increased in negative treatments amended with only T. portulacastrum and decreased in positive treatments by using biological agent Pseudomonas spp (PF- 097). By the amendment of Pseudomonas (PF- 097) protein content of mash bean seedling was significantly increased in positive treatments as compared to negative treatments.
Prediction of Hydraulic Fractured Well Performance Using Empirical Correlation and Machine Learning
Authors: Hamzah Kamal , Yasutra Amega , Irawan Dedy
Published: December 2021

Hydraulic fracturing has been established as one of production enhancement methods in the petroleum industry. This method is proven to increase productivity and reserves in low permeability reservoirs, while in medium permeability, it accelerates production without affecting well reserves. However, production result looks scattered and appears to have no direct correlation to individual parameters. It also tend to have a decreasing trend, hence the success ratio needs to be increased. Hydraulic fracturing in the South Sumatra area has been implemented since 2002 and there is plenty of data that can be analyzed to resolve the relationship between actual production with reservoir parameters and fracturing treatment. Empirical correlation approach and machine learning (ML) methods are both used to evaluate this relationship. Concept of Darcy's equation is utilized as basis for the empirical correlation on the actual data. The ML method is then applied to provide better predictions both for production rate and water cut. This method has also been developed to solve data limitations so that the prediction method can be used for all wells. Empirical correlation can gives an R2 of 0.67, while ML can gives a better R2 that is close to 0.80. Furthermore, this prediction method can be used for well candidate selection means.

Behavioral components of pro-healthy lifestyle and bioelectrical impedance body composition in Polish young adults: Preliminary results
Authors: Skrzypek Michał , Pokarowski Maciej , Partycka-Pietrzyk Kornela , Poźniak Olga , Kędra Michał
Published: December 2021

Introduction:
Adverse health behaviors changes are reported during emerging adulthood, inter alia the reduced level of physical activity (PA), worse diet quality etc. There are only very few studies concerned with the relationship between health behaviors and body composition in healthy young adults.

Aim:
The aim was to investigate the relationship between behavioral components of prohealthy lifestyle and body composition assessed by bioelectrical impedance (BIA) in the cohort of Polish young adults.

Material and methods:
A cross-sectional observational study of health behaviors, anthropometric indices and BIA body composition was conducted in Polish young adults (n = 92) aged 18–24 (mean 19.33, SD 0.915), 71 females. Behavioral variables included: general health behaviors, PA, eating behaviors and nutritional knowledge. Body composition was analyzed by means of the BIA phase-sensitive 8-electrode medical SECA mBCA 525 device.

Results and discussion:
A higher level of PA was associated with a lower volume of visceral adipose tissue in females (r = –0.27; P < 0.05). In the males, the intensification of unhealthy diet was negatively correlated with the muscle mass (r = 0.65; P < 0.01), and the higher level of nutritional knowledge resulted in a smaller waist circumference (r = –0.45; P < 0.05). Behavioral components of pro-healthy lifestyle were not significant predictors of body composition/anthropometric indices such as waist circumference, fat mass index, fat free mass index and body mass index.

Conclusions:
The reported studies provide an important insight into the sex-specific correlations between the behavioral components of the pro-healthy lifestyle and body composition in healthy young adults.

Asam lemak merupakan hasil hidrolisa dari minyak sawit, didalam minyak sawit terdapat berbagai macam asam lemak, tetapi didalam perhitungan asam lemak yang digunakan adalah asam palmitate. Selain proses hidrolisa, proses oksidasi juga dapat terjadi karena kenaikan asam lemak bebas. Air dapat menguap pada minyak sawit jika dipanaskan pada suhu 150oC, karena itu pemanasan perlu dilakukan untuk mengurangi pertambahan asam lemak bebas pada CPO dengan proses hidrolisa. Penelitian ini bertujuan untuk membandingkan antara lama penyimpanan, suhu pemanasan dan persentase air didalam minyak kelapa sawit. Metode yang digunakan yaitu persiapan bahan baku dan tahap pengujian. Untuk hasil dalam analisa asam lemak bebas dan kadar air yang paling bagus yaitu waktu penyimpanan selama 8 jam pada suhu 60oC dengan nilai asam lemak bebas (ALB) yaitu 2,5% dan kadar airnya dengan nilai 0,38%. Hasil analisa yang dihasilkan persentase air sangat berpengaruh besar dalam kenaikan asam lemak bebas (ALB) dibandingkan dengan suhu pemanasan dalam minyak kelapa sawit. Diharapkan untuk penelitian selanjutnya dapat dilakukan variasi waktu pemanasan agar memperoleh hasil yang sesuai dengan standar mutu.

Intisari
Selama ini Jakarta dikenal dengan kota berpolusi dengan indeks pencemaran udara yang cukup tinggi. Salah satu penyebab pencemaran udara adalah polutan partikulat (PM2.5) dan gas CO yang berasal dari pembakaran tidak sempurna. Pada masa pandemi Covid-19, pemerintah menerapkan  kebijakan Pemberlakuan Pembatasan Kegiatan Masyarakat (PPKM) untuk menekan jumlah penularan virus Covid-19. Jakarta Pusat sebagai salah satu kota yang melaksanakan kebijakan PPKM mewajibkan perkantoran yang ada untuk menerapkan Work From Home (WFH). Jumlah konsentrasi polusi udara PM2.5 pada periode WFH Maret 2020 tidak jauh berbeda dibandingkan lima tahun sebelumnya. Sedangkan konsentrasi CO pada periode yang sama mengalami penurunan dibandingkan lima tahun sebelumnya. Hasil analisis hubungan antara pengaruh parameter cuaca dengan konsentrasi polutan menunjukkan pengaruh parameter cuaca kurang signifikan terhadap konsentrasi PM2.5 dan gas CO. Nilai R-Square adj antara beberapa parameter cuaca terhadap konsentrasi PM2.5 dan konsentrasi CO cukup kecil. Hal ini menunjukkan bahwa pengurangan nilai konsentrasi PM2.5 dan gas CO bukan dipengaruhi oleh parameter cuaca. Faktor lain yang diduga memengaruhi konsentrasi PM2.5 dan gas CO adalah kegiatan manusia seperti WFH sehingga terjadi pengurangan aktivitas masyarakat untuk pergi ke kantor.
Abstract
Jakarta is known as a polluted city with a high air pollution index. One of the air pollution causes is particulate pollutants (PM2.5) and CO from incomplete combustion. During the Covid-19 pandemic, the government implemented a policy of Community Activity Restrictions, known as PPKM, to reduce the number of transmissions of the Covid-19. As one of the cities implementing the PPKM policy, Central Jakarta requires offices to implement Work From Home (WFH). The total PM2.5 air pollution concentration in the March 2020 WFH period was not much different from the previous five years. However, the CO concentration in the same period decreased compared to the last five years. Relationship analysis between the influence of weather parameters and pollutant concentrations shows that weather parameters are less significant on PM2.5 and CO concentration. The R-Square adj between several weather parameters on the concentration of PM2.5 and the concentration of CO is small. It means that weather parameters do not influence the reduction in the concentration of PM2.5 and CO. It is assumed that the PM2.5 and CO concentrations decreased due to fewer human activities in the office and public areas.

Exploring students' perceptions about intercultural communication education: Rethinking the design and facilitation of a course in Japan
Authors: Allen Todd James
Published: December 2021

Researchers and intercultural educators have put forward various theoretical principles and pedagogical ideas related to the design and implementation of intercultural communication (IC) courses. Recently, researchers have called for curriculum development to include students’ voices about their intercultural communication education (ICE). This paper reports on a study which examined 42 students’ perceptions of an intercultural communication course taught over one semester at a university in Japan, focusing in particular on motivations for students’ intercultural learning and their strategies for maintaining or further developing their IC competence upon completing their studies. Students were also asked to consider the significance of ICE in terms of their life experiences. Survey results revealed that participants enrolled in the IC course to reflect on their study abroad experiences, develop tangible skills for their vocations, and effectively manage IC interactions. They also claimed that learning about perceptions and IC transitions contributed to their understanding of their own experiences and broader intercultural issues. The study contributes to understanding of what students who choose to enrol in an IC course potentially seek from such a course in this context and how they interpret its significance in terms of their own goals and anticipated life trajectories. It also offers some implications for the design of future IC courses.
Computer-related metacognitive and selfefficacy beliefs of university students: A Japanese case study
Authors: Saunders-Wyndham James , Smith Eleanor , Past Travis H.
Published: December 2021

This study aims to measure student cognitive and metacognitive perceptions regarding computer use in university. This study addresses three key questions: a) how does the model fit the key construct of metacognitive and self-efficacy beliefs; b) to what degree do independent variables predict dependent factor outcomes; and c) how can understanding student metacognitive and self-efficacy beliefs inform ICT policy in education? This representative model uses four latent factors to measure student perceptions: self-efficacy (SE), computer anxiety (CA), vicarious experiences (VE), and belief of benefits (BB). This study uses a 16-item survey model to test a sample of 602 students from a university in Japan. Quantitative data were analysed using a confirmatory factor analysis to test the validity of dependent latent factors, and a multiple regression analysis to identify independent variables that can predict dependent variable outcomes. Results identify statistically significant predictors of outcome related to two of the dependent variables (self-efficacy and computer anxiety) concerning the demographic groups: a) Gender, b) Computer use age (the age when participants begin using computers), c) Computer use based on hours per day, d) Ownership of computer devices, and e) Location of computer use. Findings conclude that the tested model gives substantial insights into the cognitive and metacognitive processes of students, which can meaningfully contribute to the development of ICT policies in schools.
