STEM fields are viewed as being important for global economic development, as well as for the well-being of society. Many factors, including knowledge of future pay and other occupational insights, influence university major selection. This paper reports the findings from an empirical study of diploma, undergraduate, and postgraduate on the relationship between gender equality and university support with students’ views on STEM careers, as well as their persistence and attrition in STEM majors. The findings from PLS-SEM analysis shows that gender equality did positively affect students’ views on STEM careers and students’ persistence in STEM majors. It was also found that gender equality did not affect students’ attrition. In contrast, the university support did not positively affect students’ views on STEM careers and students’ attrition in STEM majors. However, university support was found to positively affect students’ persistence in STEM majors. The implications of the findings are that the university can channel its support systems in nurturing the students’ skills and knowledge by providing physical and psychosocial support for the students to persist in STEM majors. Hence, encouraging more students to opt for STEM majors is necessary to enhance the global economy so that it can contribute to the well-being not just of the STEM graduates, but the society and nation as well.

The intergenerational diversity of teachers in the school community offers rich resources for professional learning and development. Nonetheless, intergenerational (IG) relationship is essential for teachers to access these social resources. Hence, through a systematic grounded theory design, this study looked into the IG relationship building process among teachers in the Philippine multigenerational basic education schools, based on a contextualized understanding of the teachers’ intergenerational diversity in terms of their age, period, cohort, and professional experiences. Smooth IG Relationship Building Theory eventually emerged from the grounded data that were gathered from 20 multigenerational Filipino teachers. This grounded theory offers five theoretical propositions: (1) Multigenerational teacher community offers a wide range of resources for professional and personal development of teachers, and access to these resources is unlocked by smooth IG relationships; (2) Smooth IG relationships are hindered by generational gaps, seniority, and isolating structures and programs of the schools; (3) IG values are important to ensure that smooth IG relations do not have underlying tensions beyond the surface interactions; (4) The quality of opportunities and strategies influence the nature of relationships that could develop among colleagues; and (5) Development of smooth IG relationships among colleagues is influenced by the school culture, Filipino social relations, gender differences and IG diversity.

Published: August 2023

In this work, the molecular properties of the (E)-3-(4-nitrobenzylidene)-2-(4-methoxyphenyl)- 2,3-dihydro-1-(phenylsulfonyl)-quinolin-4(1H)-one were studied, both in a solid and isolated state. The effect of changing the substituent groups –OCH3 and –Cl in the phenyl portion was verified, where the structural and electronic properties were compared. The density functional theory was employed using the hybrid exchange-correlation functional with long-range correction M06-2X, combined with the polarized and diffuse basis set 6-311++G(d,p), in the gas phase. The electronic structure was also analyzed by frontier molecular orbitals and molecular electrostatic potential maps, where information about its chemical reactivity was obtained. Also, the supramolecular arrangement was analyzed by Hirshfeld surface (HS), 2D fingerprint plots, and quantum theory of atoms in molecules (QTAIM). The natural bond orbitals (NBO) calculations were carried out to analyze the stability and hyperconjugation energy. Finally, molecular docking was carried out to investigate the affinities of the quinoline-chalcone with a bacterial protein (Agrobacterium pathogens) and an ecdysone receptor-potential pesticidal activity. The results encourage further in vitro and in vivo analyses of the two kinds of organisms investigated.
Geomorphometric based catchment runoff characterization and assessment of temporal landuse change impact on runoff inflow to an ungauged reservoir under different climatic scenarios using geospatial techniques and SWAT model
Authors: Prasad Vishnu , Bhardwaj Anil
Published: August 2023

A morphometric analysis was carried out to study runoff characteristics of the Saleran reservoir catchment. Further, the impact of catchment landuse change on runoff generation and inflow to the Saleran reservoir has been assessed using geospatial techniques and SWAT. The geomorphometric analysis shows that the catchment is less elongated in shape, having fourth-order stream network, high stream frequency (9.36 no./km2), drainage density (4.55 km/km2) and high relief (220 m), which indicates that catchment would generate a moderate amount of runoff. The SWAT (ArcSWAT) model was used for the simulation of runoff and the average annual runoff inflow was simulated to be 14.2 mm (1995–1999), 13.2 mm (2000–2009) and 11.8 mm (2010–2019) per 100 mm of rainfall under the landuse 1999, 2009 and 2019, respectively. The results indicated that the temporal change in catchment landuse has significantly increased the runoff generation and its inflow to the reservoir but there is a decrease in the volume of runoff inflow which may be due to the decreasing trend in monsoon rainfall. Hence, an appropriate conservation strategy needs to be developed and adopted in the Shivalik foot-hills for managing the catchment landuse for sustainable water supply through reservoirs.

Published: August 2023

Contaminants of emerging concern (CECs) and their respective transformation products (TPs) formed following photodegradation pose considerable threats to the environment and our health. The formation of TPs during UV-LED-based degradation of three target pollutants in the EU Watch List of CECs was accessed by LC-MS-Orbitrap, and their reaction pathways were elucidated. The influence of different matrices and treatments of choice on TP formation was investigated. Results showed that matrix changes did not produce different reaction pathways during UV-A photocatalysis, although plots of TP peak areas vs. time were different for each case. A new TP was found for the antidepressant venlafaxine, (1-[2-(dimethylnitroryl)-1-(4-methoxyphenyl)ethyl]cyclohexanol. When comparing UV-A photocatalysis with UV-C photolysis, dissimilar pathways were observed due to the distinct reaction mechanisms of each process, since photocatalysis, unlike photolysis, relies on radical-based reaction routes. Different levels of confidence were obtained for each TP depending on the availability of MS2 data in the literature and of standards for comparison. All the found TPs had similar molecular masses in comparison to their respective parent compounds. Most of the TPs remained in the effluent after 6 hours of photodegradation, which highlights the importance of their control, close-monitoring, and further toxicity assessments.
The impact of solid/floc holdup on oxygen transfer in a rotating hollow fiber membrane bioreactor under endogenous conditions
Authors: Mahdariza Fathul , Georg Wilhelm , Wille Ernst-Marius , Morck Tobias
Published: August 2023

A set of oxygen transfer experiments in clean water and three different activated sludge concentrations were conducted with fine and coarse bubble aeration in a rotating hollow fiber membrane bioreactor to observe the impact of different rotational speeds on the oxygen transfer rate. The results showed that with increasing membrane rotational speed, the oxygen transfer coefficient enhanced while the α-factor showed similar values at comparable sludge concentrations and solid/floc holdups. The highest improvement rates occurred during the experiments with coarse bubble aeration at 50 rpm and the lowest specific airflow rate. The solid/floc holdup appears to universally impact oxygen transfer depletion regardless of what reactor type, diffuser setup and membrane rotational speed were used in the wastewater experiments.
Saltwater Intrusion Impacts Microbial Diversity and Function in Groundwater Ecosystems
Authors: Houghton Karen M. , Fournier Mano , Tschritter Conny
Published: August 2023

Background:

Groundwater ecosystem services provided by microbial communities are essential for the maintenance of water quality. For example, nitrate contamination is a recognised health and ecosystem issue in most groundwater systems, often alleviated through microbial processes. The effects of climate change, including increasing salinity from rising sea levels, or over-abstraction, on these communities are largely unknown.

Methods:

This study uses a combination of culture-dependent (growth curves, isolation of bacteria) and culture-independent (16S rRNA gene sequencing) methods to identify the potential effects of saltwater intrusion on groundwater microbes and their ecosystem functions.

Results:

Some groundwater microbial communities are negatively impacted by increasing chloride concentrations, including declines in bacteria responsible for nitrate and ammonia removal. These ecosystems should be prioritised for future protection from sea level rise or increased extraction of groundwater for agriculture and other uses. Other microbial communities are stimulated in the presence of chloride, often caused by an increase in abundance of salt-tolerant heterotrophic bacteria using sugars, peptides, or organic acids for energy.

Conclusion:

There have been no previous studies investigating the impact of chloride on Aotearoa New Zealand groundwaters. The identification of keystone species that are affected by increasing salinity, which have a disproportionately large effect on the ecosystem and low functional redundancy, is essential. Water management decisions about future abstraction limits and defences against sea level rise can be underpinned by robust scientific knowledge about microbial community sensitivity to salinity.

Published: August 2023

Ionic liquids (ILs) are presently one of the most interesting research fields gaining vast attention from researchers from multidisciplinary research
areas worldwide. Without any ambiguity, ionic liquids or molten salts, neoteric materials have become a significant and crucial area under study
for the exploration of the science of molecules. The data in the literature emphasises that a plethora of papers have been published on ionic liquids
each year. These neoteric materials have been the subject of several major reviews and books, dealing with different explorations and aspects of
their behaviours. The supramolecular material called cyclodextrin (CDs), and their ability to form inclusion complexes with ILs due to their
hydrophobic and hydrophilic properties, is well known to date. This review offers a vision of the chemical behaviours of ionic liquids complexes
using cyclodextrins. The review takes care of different sections related to i) introduction of cyclodextrin, ii) history of ionic liquids, iii) history of
inclusion compounds, iv) general methods for the formation of inclusion complexes, and v) the inclusion complex formation of ionic liquids with
cyclodextrins.

Combined Model
Authors: Shan Ruiqing , Niu Jitao , Chai Xuzheng , Gu Qingfa
Published: August 2023

Background:

Increasing the accuracy of the output power forecasting for wind power
is helpful to the improvement of the reliability of power dispatching.

Objective:

This study aimed to improve the forecasting accuracy of mid-to-long term wind
power.

Methods:

A mid-to-long term wind power forecasting based on ARIMA-BP combined model
was proposed. The Empirical Mode Decomposition (EMD) was used to decompose the historical
wind power series and obtain the Intrinsic Mode Function (IMF) and residual components,
thereby obtaining more regular components. Then, the optimum feature set was obtained based
on the minimum Redundancy Maximum Relevance (mRAR) to improve the prediction accuracy
for feature extraction. After that, the high-frequency components were predicted using the Back
Propagation (BP) neural network model, while the low-frequency components were predicted
using the Autoregressive Integrated Moving Average model (ARIMA). Finally, the predicted
components obtained were superimposed to deduce the final mid- and long-term wind power
prediction results.

Results:

An analysis was conducted according to the actual data from a typical wind farm. After
comparison, it was found that, after empirical mode decomposition and feature extraction analysis,
the error of the intelligent combination algorithm based on the ARIMA-BP combined model
was smaller than that using only the BP neural network or only the ARIMA.

Conclusion:

By means of actual data analysis, the effectiveness of the method proposed by the
study for mid- and long-term wind power prediction was verified.

Published: August 2023

Hematite is an n-type semiconductor, and its semiconducting properties can
further be improved by nano-structuring and doping. In several optoelectronic devices,
such as thermoelectric and solar cells, both n- and p-type semiconductors are required.
The p-type hematite can be synthesized by doping cations, such as Ni2+, Mg2+, Cu2+, and
Mn2+. Furthermore, hematite is a weak ferromagnetic material, and its magnetic
properties vary with the size of nanoparticles, doping of cations as well as doping
concentration. This chapter discusses various properties of nanostructured nickel-doped
hematite. As nickel is a ferromagnetic divalent dopant with a high magnetic moment,
its doping in hematite together with nano-structuring shows a large variation in both
electrical and magnetic properties in nickel.

Published: August 2023

Carbon nanotubes (CNTs) composed of sp2
carbon units oriented as one
rolled-up graphene have provided exceptional advances in the design of chemical
sensors for environmental and health monitoring. The remarkable properties of CNTs,
such as high active surface area, chemical inertness, high strength, high electrical
conductivity, excellent thermal stability, and low charge-transfer resistance, have made
them a potential candidate for the detection of various explosive, combustible, and
toxic gases, such as hydrogen sulfide (H2S), nitrogen oxides (NOx
), ozone (O3
), and
halogens (Br2
, Cl2
, and I2
). However, CNT-based sensor shows issues like low
sensitivity and slow response/recovery time due to minimum charge transfer between
the pristine CNTs and target analytes. The functionalization of CNTs with metal
oxides, noble metal nanoparticles, and organic semiconductors not only improves the
gas sensing parameters but also enhances their selectivity toward a particular type of
target analyte due to the better charge transfer between the composite and gas analytes.
This book chapter focuses on the ways to create CNT-based sensors exhibiting
selective responses to different target analytes, future developments in the field of
chemical sensors, and the viewpoint of their commercialization.

Land of peaceful separatists – the Szeklerland in Romanian media
Authors: Zahorán Csaba
Published: August 2023

In Romanian media, Szeklerland — a region in Central Romania with an ethnic Hungarian majority – is often evoked as a troublesome part of the country, where Romanians are discriminated against and Hungarian separatism undermines the authority of the state. This representation has endured since the fall of Communism in 1989, even though — unlike in other regions of Europe — the local Hungarian autonomist movement has always relied on peaceful means. The mainstream Romanian discourse, with its focus on the political efforts of Hungarian parties, the symbolic rivalry between Hungarian and Romanian elites, and the fight for economic resources has largely been unchanged. This conflict-oriented perspective makes for a skewed and ethnicized representation of Szeklerland, portrayed as an ‘intolerant region’. While the region witnessed only a minor Hungarian–Romanian conflict in March 1990, the topics of instability and constant tension pervaded the media discourse regarding Szeklerland during the 1990s. Even though the dominant nationalist discourse has become less virulent, this pattern has persisted with the advent of digital and new media formats. Many contemporary representations of Szeklerland on commercial television and social media platforms keep reproducing the stereotypes inherited from the 1990s. This article is based on a historical approach, and, through the analysis of several recent Romanian short documentary films about the Szekler area, highlights the reproduction of the region’s imagery and the most common strategies that feed this polarizing representation.

Using COVID-19 Vaccine Attitudes on Twitter to Improve Vaccine Uptake Forecast Models in the United States: Infodemiology Study of Tweets (Preprint)
Authors: Sigalo Nekabari , Awasthi Naman , Abrar Saad Mohammad , Frias-Martinez Vanessa
Published: August 2023

BACKGROUND

Since the onset of the COVID-19 pandemic, there has been a global effort to develop vaccines that protect against COVID-19. Individuals who are fully vaccinated are far less likely to contract and therefore transmit the virus to others. Researchers have found that the internet and social media both play a role in shaping personal choices about vaccinations.

OBJECTIVE

This study aims to determine whether supplementing COVID-19 vaccine uptake forecast models with the attitudes found in tweets improves over baseline models that only use historical vaccination data.

METHODS

Daily COVID-19 vaccination data at the county level was collected for the January 2021 to May 2021 study period. Twitter’s streaming application programming interface was used to collect COVID-19 vaccine tweets during this same period. Several autoregressive integrated moving average models were executed to predict the vaccine uptake rate using only historical data (baseline autoregressive integrated moving average) and individual Twitter-derived features (autoregressive integrated moving average exogenous variable model).

RESULTS

In this study, we found that supplementing baseline forecast models with both historical vaccination data and COVID-19 vaccine attitudes found in tweets reduced root mean square error by as much as 83%.

CONCLUSIONS

Developing a predictive tool for vaccination uptake in the United States will empower public health researchers and decisionmakers to design targeted vaccination campaigns in hopes of achieving the vaccination threshold required for the United States to reach widespread population protection.

Published: August 2023

BACKGROUND

Nephrolithiasis is a prevalent urological disease that affects 10% to 15% people worldwide. It is not only a painful and debilitating disease but it is also placing a significant financial burden on the healthcare system. Overweight and obese individuals have a 1.5 to 2.5-fold increased risk of developing kidney stones, but there was no rapid and simple screening test for nephrolithiasis in asymptomatic populations.

OBJECTIVE

Our aim is to build and evaluate models to screen for clinically significant nephrolithiasis in overweight and obesity populations using machine learning (ML) methodologies and simple health checkup clinical and urine parameters easily obtained in clinics.

METHODS

We developed several models to screen for clinically significant nephrolithiasis 2mm kidney stones) in overweight and obesity populations using ML methodologies and simple health checkup clinical information, including gender, age, body mass index (BMI), the presence or absence of gout, the presence or absence of diabetes mellitus, estimated glomerular filtration rate, bacteriuria, urine pH, urine red blood cell counts, and urine specific gravity. Then, socio-demographic, health, and clinical data were collected from overweight and obese people (BMI≥25 kg/m2) with and without clinically significant nephrolithiasis from hospitals in Kaohsiung, Taiwan between 2012 and 2021. Data obtained from 2012 to 2019 were used for model training and validation (ratio 3:1). Data obtained from 2020 to 2021 were used for model testing.

RESULTS

Of the 2928 subjects we enrolled, 1148 (39.21%) had clinically significant nephrolithiasis and 1780 (60.79%) did not. The testing dataset consisted of data collected from 574 subjects, 235 (40.94%) with clinically significant nephrolithiasis and 339 (59.06%) without. One model had a testing area under curve of 0.965 (95% CI, 0.9506-0.9794), a sensitivity of 0.860 (95% CI, 0.8152-0.9040), a specificity of 0.947 (95% CI, 0.9230-0.9708), a positive predictive value of 0.918 (95% CI, 0.8820-0.9544), and negative predictive value of 0.907 (95% CI, 0.8756-0.9371).

CONCLUSIONS

This ML-based model was found able to effectively distinguish the overweight and obese subjects with clinically significant nephrolithiasis from those without. We believe that such a model can serve as an easily accessible and reliable screening tool for nephrolithiasis in overweight and obesity populations and make possible early intervention such as lifestyle modifications and medication for prevention stone complications.
Virtual Reality in Nursing over the Past Ten Years: An Umbrel-la Review of Meta-Analyses (Preprint)
Authors: Hu Yanjie , Yuan Xingzhu , Ye Peiling , Chang Chengting , Hu Yuehan , Zhang Weihua , Li Ka
Published: August 2023

BACKGROUND

VR has shown promising levels of effectiveness in various scenarios, such as nursing education, pain management and rehabilitation. Current meta-analyses have discussed the effects of VR usage in nursing unilaterally and inconsistently, and the evidence base is diffuse and varied.

OBJECTIVE

This umbrella review aimed to synthesize the combined evidence from meta-analyses assessing the effects of nurses using virtual reality technology on nursing educations or patient health outcome.

METHODS

We conducted an umbrella review by searching Web of Science, Embase, Cochrane, PubMed and the reference lists of relevant studies. Eligible
reviews published between 1 December 2012 and 1 December 2022. Appraised the quality of reviews using the AMSTAR and the GRADE Checklist for Systematic Reviews and meta-analysis.

RESULTS

63 meta-analyses were included. The most VR study conditions were neuronursing(33%), neo-natal(26%), gerontic(8%), oncological(6%),wound care(5%) and nursing education(8%), and the problems expected to solve were pain(17%),anxiety(15%),motor(12%) and cognitive(8%) function and depression(7%).VR treatment on cognitive function, pain and depression is effective in neu-rological, neonatal, chronic & aging, breast cancer and wound patients, while it is controversial on anxiety for education and carcinoma other than breast cancer. Symptoms of adverse event were reported mainly including nausea, vomiting, dizziness. The prevalence of adverse reac-tions ranged from 4.76%-50% where VR interventions were used. Most of these meta-analyses are meta-analyses of randomized controlled trials. Approximately 61% were rated as very low, 27% as low, and 9% as moderate on the GRADE scale.

CONCLUSIONS

VR in nursing has a positive effect on relieving patients' anxiety and pain and improving cognitive function; The application of nursing VR in nursing education and improve patients' motor function, memory and attention is still controversial. Nursing researchers need to further explore the effect of VR on anxiety, pain, cognitive impairment and rehabilitation training, promote the clinical application of VR technology with practical clinical significance, and judge the trade-off between the actual benefits of VR use to patients and the human cost of VR equipment development costs, and more high-quality nursing VR articles are needed.

Gudeg producers as one of the MSMEs in the traditional culinary also have various types of work accident risks in their production process, including in the process of producing Gudeg Chicken. Overall, the process of producing Gudeg Chicken includes sorting, washing, cooking, and distribution. The results of the initial observations indicated that workers in sorting division had the complaints of back pain and several work accidents have occurred in the production division of Gudeg Chicken. Hence, it is deemed necessary to analyze the risk of work accidents occurred. The analysis of work accident risks was done using the Failure Mode and Effect Analysis (FMEA) method by considering severity, occurrence, and detection values to obtain a Risk Priority Number (RPN). The results were then analyzed using a Pareto diagram to determine the work accident with the highest risk. Recommendations for improvement were given using the Hazard Identification Risk Assessment and Risk Control (HIRARC). The results showed that the highest risk of work accidents was related to the position of sitting that is not ergonomic in the process of sorting Gudeg Chicken. The elimination of these risks does not need to be carried out, but it needs to do substitution of production areas, engineering controls with modifications towards the tables or chairs of employees, administrative controls, and the use of Personal Protective Equipment.

Impact of Tourism on Soil Erosion in Tourist Area of KaliurangTourism is one alternative of non timber based forest managements however, tourism activities will impact on the tourist areas, both biophysically and socially. The purpose of this research was to study the factors influencing soil erosion rate in tourist area, and to examine the effect of tourist characteristics, e.g. visiting characteristics and tourist activities on erosion rate.The erosion prediction was carried out at tourist areas including Hutan Alam (Natural Forest), Taman Bermain Anak (Play Ground), Taman Wisata Alam (Natural Tourist Park), and Kali Kuning Camping Ground. The Universal Soil Loss Equation (USLE) model was applied. Correlation analysis was used to analyze the correlation between factors influencing soil erosion rate (rainfall erosivity, soil erodibility, slopes, vegetation and conservation practices) and erosion.The research resulted that tourism significantly impacted on erosion at Play Ground, Natural Tourist Park 1, and Kali Kuning Camping Ground, except at Natural Tourist Park 2. The correlation analysis showed that all of the factors influencing soil erosion rate positively affected erosion. The results also showed that the tourist characteristics which influence erosion rate were tourists' visiting characteristics and their activities.

Kabupaten Gunungkidul dulu terkenal tandus kering gersang pada tahun 1940-1970-an tetapi kini telah menjadi hijau kembali. Proses ini disebut dengan proses transisi. Penelitian ini memberikan bukti empirik melalui alat bantu analisis perubahan spasial dan penginderaan jauh yang hasilnya kemudian digunakan untuk memodelkan proses tahapan transisi sebagaimana model menurut Mather (1992) dan Hosunuma (2002). Tahapan transisi saat ini menurut model tersebut adalah menuju tahap akhir dari proses pertumbuhan. Yang unik dari proses transisi di wilayah ini adalah model penutupan/penggunaan lahan yang dominan dengan bentuk pemukiman/pekarangan, sawah tadah hujan dan tegalan/ladang (sesuai SNI 7645-2010). Model ini dapat dikatakan merupakan model penyusun ekosistem baru yang terjadi dalam proses transisi yang berbeda dari model penutupan sebelumnya yang berupa hutan campuran sebagaimana dijelaskan oleh Nibbering (1991). Model ini merupakan bentuk kompromi sosial-ekologis hasil proses rehabilitasi saat itu yang dilakukan baik oleh masyarakat maupun oleh Pemerintah Daerah dengan program INPRES Penghijauan dari Pemerintah Pusat saat itu. Pembelajaran yang menarik dari proses transisi adalah kembalinya lahan bervegetasi menjadi sebuah ekosistem baru di Gunungkidul melalui dominasi penutupan/penggunaan lahan pemukiman (pekarangan), sawah tadah hujan dan tegalan/ladang. Bentuk-bentuk ini merupakan proses kompromi yang menjadi faktor keberhasilan rehabilitasi yang dilakukan saat itu.Katakunci: Gunungkidul, transisi hutan, rehabilitasi, perubahan spasial, penginderaan jauh Analysis on the Land Transition in Gunungkidul using Multi Temporal Remote SensingAbstractGunungkidul was well known as barren area during 1940-1970 but now becomes fully vegetated. This process called the transition process. This study provided empirical evidences by spatial changes and remote sensing analysis and then the results were used for modelling of  the transition phases according to Mather (1992) and Hosunuma (2002). According to the model, the current transition phase is close to the final stage of the growth process. A unique phenomenon of the transition process of re-vegetation is that the regions dominated by settlement/yard, rain fed and upland/fields (in accordance to SNI 7645-2010). This model could be categorize as model of new ecosystem in the transition process, which is different from the previous one. The previous model was in the form of mixed forest as described by Nibbering(1991). This model is a compromise form of socio-ecological aspect as a result of the rehabilitation process, which was conducted by either the public or the Local Government based on Greening  Program of the Central Government according to Presidential Instruction. Interested learning from the process of re-vegetation transition is that the formations of re-vegetation lead to a new ecosystem in Gunungkidul through the dominance of settlement, rain field and upland.

Tujuan penelitian ini adalah untuk mengetahui kualitas kayu cacat. Spesimen penelitian berupa 10 pohon miring yang diperoleh dari kegiatan penjarangan dari tegakan jati (Tectona grandis L.f.) di Randublatung, Jawa Tengah. Pada setiap pohon, kayu di bagian eksentrisnya dipisahkan \, kemudian sampel serbuk kayu diambil pada bagian teras terluar pada kedua lebar lingkaran tahun maksimum (bagian atas pohon miring) dan pada arah yang berlawanan, yaitu yang mempunyai lebar lingkaran tahun minimum (bagian bawah pohon miring). Serbuk kayu dihaluskan sampai mencapai 40-60 mesh untuk analisis kimia. Analisis data melalui uji t pohon pada kadar ekstraktif etanol-benzena (4-12%), kadar terlarut air panas (1-3%), kadar abu (0,7-3%) dan kadar lignin terlarut asam (0,7-1,4%). Pengukuran menggunakan GC dan GC-MS, menunjukkan tidak ada beda yang mencolok pada jumlah komponen utama ekstraktif etanol-benzena. Sebaliknya, kayu dengan lingkaran tahun paling lebar secara konsisten memiliki kadar lignin Klason lebih tinggi (32-35%) dibandingkan kayu dengan lingkaran tahun sempit (29-33%). Hasil-hasil tersebut menunjukkan bahwa eksentris lebih berkaitan dengan komponen dinding sel kayu daripada zat-zat metabolism sekunder. Selanjutnya, tidak terlihat juga adanya indikasi terhadap pembentukan kayu tarik.Kata kunci: Tectona Grandis, kayu eksentris, pohon miring, sifat kimia, riap tumbuh. Chemical Components of Teak Wood with Eccentric Growth AbstractThe objective of this study is to learn the quality of abnormal woods. The specimens were 10 leaning trees obtained from thinned teak (Tectona grandis L.f.) stand in Randublatung, Central Java. In each tree, the eccentric growth parts were isolated, then wood meal sample was drilled at the outer heartwood part of both maximum annual-ring width (upper part of leaning stem) and in its opposite side, which had minimum annual-ring width (lower part of leaning stem). The wood meals were ground to size of 40-60 mesh for chemical analysis. Data analysis by paired t-test showed that no significant difference was found between the upper and lower parts in ethanol-benzene extractive content (4-12%), hot-water soluble content (1-3%), ash content (0.73%) and acid soluble lignin content (0.7-1.4 %) . By means of Gas Chromatography (GC) and Gas Chromatography-Mass Spectrometry (GC-MS), no striking difference was also observed in the levels of major components of ethanol-benzene extracts. On the other hand, in Klason lignin content, the wood with widest ring consistently showed a higher content (32-35 %) than that with narrowest ring (29-33 %). These findings indicated that the eccentricity is more related to cell wall components than to secondary metabolites. Further, there is no indication with regard to the formation of tension wood.

Similar to other botanic gardens, Bali Botanic Garden (BBG) is also prone to the spread of Invasive Alien Plant (IAP) species. Unfortunately, research about IAP species in BBG is still very limited. Thus, the study aims to update the list of IAP species in BBG and its adjacent areas as well as to provide a garden manager with data of the most important IAP species. This study was conducted by using sampling plots that were purposively established in three areas of BBG, namely the Ekor Burung (EB), VIP, and Kepala Burung (KB). Data analysis was performed to calculate the Relative Frequency (RF), Important Value Index (IVI), Clustering analysis, and NMDS ordination. The study was able to document 18 IAP species. Ageratina riparia and Bidens pilosa have the highest RF in EB, while the former also has the highest RF in VIP and KB. Similarly, the highest IVI was acquired by A. riparia in VIP and KB, as well as by Sida rhombifolia in EB. Cluster analysis revealed two subsets. NMDS ordination suggested that VIP and KB have more similar IAPs than the EB. This study suggested that A. riparia is the most important IAP species in BBG and its surrounding areas.Inventarisasi Tumbuhan Asing Invasif di Kebun Raya Bali dan Wilayah Sekitarnya IntisariSepertihalnya Kebun Raya lain, Kebun Raya Bali (BBG) juga rentan terhadap penyebaran Tumbuhan Asing Invasif (IAP). Sayangnya, penelitian tentang IAP di BBG dan daerah sekitarnya masih sangat terbatas. Karena itu, penelitian ini bertujuan untuk memperbarui daftar jenis IAP di BBG dan daerah sekitarnya serta menyediakan data jenis IAP paling penting bagi pengelola Kebun Raya. Penelitian ini dilakukan dengan menggunakan plot sampel yang secara purposive diletakan pada tiga wilayah BBG yaitu Ekor Burung (EB), VIP dan Kepala burung (KB). Analisis data dilakukan untuk menghitung Frekuensi Relatif (RF), Indeks Nilai Penting (IVI), analisis klaster dan ordinasi NMDS. Penelitian ini mampu mendokumentasikan 18 spesies IAP. Ageratina riparia dan Bidens pilosa memiliki nilai RF tertinggi di EB, sementara yang disebutkan pertama juga memiliki RF tertinggi di VIP dan KB. Demikian pula, nilai IVI tertinggi di VIP dan KB diperoleh oleh A. riparia serta oleh Sida rhombifolia di EB. Analisis klaster mengungkapkan dua subset. Ordinasi NMDS menunjukan bahwa VIP dan KB memiliki jenis-jenis IAP yang lebih mirip daripada EB. Studi ini juga menunjukkan bahwa A. riparia adalah jenis invasif paling penting di BBG dan daerah sekitarnya.
