Published: April 2023

Recently, science, technology, engineering and mathematics (STEM) applications have become more demanding, promoting students' interest in science from an early age. Science class in primary school needs more attention to attract students’ interest. This study aims to develop an inquiry- based module with scientific equipment for the primary school level to optimize science learning at the primary school level. The development process used a 4-D (define, design, develop and disseminate) model. The developed module and equipment cover the topics of forces and include four experiments, i.e., exploring friction in inclined planes, exploring the mechanical advantage of a pulley, observing magnetic force and exploring static equilibrium in a lever. The modules and scientific equipment are distributed to some schools in Indonesia that lack practical work facilities. The inquiry-based modules and scientific equipment are implemented in classes at four primary schools in Indonesia. In this study, the students' response to the implementation of inquiry-based modules and scientific equipment in the class is also investigated. Overall, the average of the students' responses is 3.37 (out of 4.00). It means students respond positively to the learning activity and the supporting module. Active learning with an inquiry approach is feasible to attract students' interest in science.

Published: April 2023

A queima das bainhas, causada pelo fungo Rhizoctonia solani é uma doença de extrema importância e de difícil manejo por se tratar de um fungo habitante de solo, que produz estrutura de resistência chamada de escleródios, ocasionando perdas de até 50% na cultura do arroz. O objetivo deste trabalho foi avaliar a resistência de 20 genótipos de arroz irrigado à queima das bainhas, em condições de campo e em casa de vegetação. As avaliações de severidade da doença foram realizadas através de uma escala de notas de 0 a 9. Em campo, o genótipo BRS Pampeira se mostrou mais resistente à doença, com média da Área Abaixo da Curva de Progresso da Doença (AACPD) de 68,25%. Houve diferença estatística em comparação aos genótipos AB191186 e AB191157 que obtiveram os maiores valores de AACPD correspondendo à 98,25% e 107,63%, respectivamente, evidenciando a alta susceptibilidade de ambos à queima das bainhas. Em condições controladas, BRS A705 se manteve mais resistente, possuindo uma AACPD de 22,13%, mas não deferiu estatisticamente da BRS Pampeira. Já os genótipos AB191186 e AB191157 mantiveram a alta susceptibilidade à doença em condições controladas.

Authors: Dinurrosifa Rahmawati Salsa , Indriyanti Erwin 
Published: April 2023

<p>Clove oil is an essential oil from the clove plant (<em>Syzygium aromaticum</em>) containing eugenol compounds. One of the properties of eugenol is as an anti-inflammatory with a mechanism of inhibition of prostaglandin synthesis and neutrophil chemotaxis. Several derivatives of eugenol have active compounds that have been developed into new drug compounds as anti-inflammatory such as acetyl eugenol (4-allyl-2-methoxyphenyl acetate). This study aims to determine the % yield of acetyl eugenol produced from synthesis using ultrasonic 0.0323 mol of eugenol added to Erlenmeyer, and 0.25 mol of 10% sodium hydroxide was added. The mixture was put in a sonicator for 15 minutes and heated at 60<sup>0</sup>C. Then, 0.0974 mol acetic anhydride was reacted with DCC, added to the mix and sonicated with time variations (60, 80, and 100 minutes). The chemical structure was elucidated using FTIR, ATR, and GC-MS. The synthesized % yield is 32.75%. Based on the interpretation data from FTIR, 3405 cm<sup>-1</sup> is an O-H group (free phenol), 1405 cm<sup>-1 </sup>is an alkene group (C=C) aliphatic, and 1560 cm<sup>-1</sup> is an aromatic compound with the presence of a C=C aromatic bond. The presence of the (C-O) ether group is indicated in the wave number at 1301 cm<sup>-1</sup>. The C=O ester bond in the ester group is shown at 1700 cm<sup>-1</sup>. GC-MS shows that the synthesized compound has a molecular ion with m/z = 206. According to the molecular weight of acetyl eugenol of 206 g/mol, it can be concluded that acetyl eugenol was successfully synthesized. The most stable ionic fragment, 37, has a molecular weight of m/z = 164. The activities of anti-inflammatory, acetyl eugenol compounds at 400 concentration ppm get % inhibition of 32.20%.</p><p class="Standard"><strong><em> </em></strong></p>

Published: April 2023

Abstract
Poor management of water sources is one of the major challenge for developing nations to provide safe water to increasing population. The Central Ground Water Board, India 2019 reports that all 13 zones of Jaipur city are in the dark zone. Dark zones are those area where the ground water exploitation is extremely high and are notified for protection by the State Government. With a population of 4.1 million, Jaipur city has a water demand deficit of around 125 MLD with dependence on ground water is increasing tremendously. The city's water table has gone down 25 metres in the last decade. Higher concentrations of fluoride, nitrate, and total dissolved solids, is a common problem in the city's ground water. Presently the city gets its water from Bisalpur dam which is 120 km away, proved to be a very costly arrangement. This paper analyses the various contaminants present in ground water. A detailed survey and data collection was done, which was further analysed through GIS spatial distribution, predicting the concentration in all 91 wards of the city. Results show that some wards are at a critical point in terms of deteriorating water quality to be addressed by city planners and urban local bodies.

Abstract
Stormwater harvesting via managed aquifer recharge in retrofitted infrastructure has been posited as a method for resource augmentation in Cape Town. However, the existing guidelines on stormwater retrofits are technically inclined, occidental, and generally misaligned with the realities and socio-economic contexts of developing nations like South Africa. Water and urban practitioners from developing nations cannot just 'copy and paste' existing guidelines as different socio-economic dimensions and colonial histories typically hinder 'traditional' approaches. This paper assesses how a transdisciplinary team navigated these realities in a case study of a retrofitted pond in Mitchells Plain, Cape Town. A decolonial thinking framework was applied for reflection and thematic content analysis. The framework was used to unpack how the team encountered, addressed, and learned from the challenges during the retrofit process. The research team found that the retrofit process within a context of under-resourced South African communities can be viewed as developmental work with a strong emphasis on continuous community engagement. Thus, it is suggested that in the South African context, water practitioners should consider, at the fore, interaction with local communities, including awareness of racialised histories, to ensure projects are successfully implemented and completed.
International Water Comprehensive Organization (IWCO): Creating alliances for improved water management and solving water conflicts
Authors: Abdi Babak , Bozorg-Haddad Omid , Loáiciga Hugo A. 
Published: April 2023

AbstractInternational organizations constitute the basis to increase water co-operation, prevent or reduce the possibility of conflicts between countries, and, were they to occur, achieve co-operation to resolve them. The proliferation of water-related conflicts, especially involving transboundary watersheds, the need for stakeholder co-operation, and the necessity of creating alliances between water organizations call for the formation of an organization to tackle the resolution of such conflicts. River Basin Organizations (RBOs) have been created in the water field in recent years, which have addressed a variety of water-related problems. Yet, there is no holistic agency at present tasked with the comprehensive review and resolution of water conflicts worldwide. This paper presents a plan to create an International Water Comprehensive Organization (IWCO) under the auspices of the United Nations that would address water conflicts worldwide, which would integrate other existing organizations with jurisdiction in the realm of water management. Furthermore, this work describes the objectives and needs for creating the IWCO, defines its structure, and outlines its main tasks and authorities. The IWCO would integrate existing water-related organizations for solving hydropolitical issues, and would provide logistic support leading to scientific and legal advances in the water field.

Abstract
This study emphasizes the possible utilization of carbonized microplastic particles (CMPs) prepared from polyethylene terephthalate (PET) plastic bottle waste for dye adsorption. Methylene blue (MB) and methyl orange (MO) are adsorbed in a batch experiment to determine the effects of various experimental factors, including contact time (1–210 min), solution pH (3–11), adsorbent dosage (1–20 g/L), temperature (25–600 °C), and initial dye concentration (5–70 mg/L). The variance analysis (ANOVA) results of response surface methodology (RSM) indicated that the second-order model was statistically significant and had a high coefficient value (R2 = 0.99 for MO and R2 = 0.92 for MB). The RSM results stated that solution pH and adsorbent dose significantly influence MO and MB dyes removal, where the maximum adsorption removal was 99.95 and 99.04% for MO and MB dye at high acidic (pH 3) and alkaline (pH 11) conditions, respectively, with high adsorbent doses. Furthermore, trained neural networks demonstrated a strong correlation between the experimental and projected colour removal efficiencies. The adsorption data for MO and MB were well explained by pseudo-second-order kinetics and Langmuir isotherm models. A thermodynamic study shows that dyes adsorptions are favourable, exothermic, and spontaneous. Finally, real wastewater and desorption studies indicate the effectiveness and environmentally friendly properties of CMPs.

Abstract
The Narmada basin is one of the major river basins of Central India. The basin frequently experiences droughts and floods due to its geography and uneven topography. Therefore, it is important to understand the spatiotemporal variability of hydroclimatic extremes over the basin. Large-scale climate oscillations (LSCOs) have been observed significantly affecting the patterns of hydroclimatic extremes at the basin and continental scale. In this study, we have analysed the relative influence of LSCOs (EL Nino-Southern Oscillation (ENSO), Indian Ocean Dipole (IOD), and Atlantic multidecadal oscillation (AMO)) over hydroclimatic extremes of the Narmada basin. Precipitation, temperature, and streamflow extremes were analysed in stationary and nonstationary frameworks of generalized extreme value distribution. The precipitation extremes, PRCPTOT and R95p were observed significantly influenced by ENSO, IOD, and AMO individually whereas extreme Rx5day was relatively more influenced by ENSO and AMO individually and collectively. Temperature extremes, TXx was significantly more influenced by ENSO alone (26.47% of the region), while TNx was observed to be substantially more influenced by ENSO and AMO. The upper Narmada basin was found vulnerable to flooding and whereas the basin was projected to experience more frequent and intense heatwave-associated disasters in long term.
