Green Pesticide High Activity Based on TiO Nanosuspension Incorporated Silver Microspheres Against .

Cocoa pod production has experienced a significant decline due to attacks by the () fungus, which is the main cause of cocoa pod rot. To overcome this problem, Titanium dioxide (TiO) was chosen because of its potential as an antifungal, and its activity can be increased by adding silver nanoparticles (AgNPs). This research aims to determine the antifungal properties of TiO-Ag nanosuspension on the growth of under exposure to UV, Visible and without irradiation.

Local knowledge as the basis of disaster management and humanitarian assistance.

Recent policy discourse on the localisation of disaster management and humanitarian assistance lacks attention to the culture, history, and traditions of the Global South. This special issue of Disasters argues that it is imperative to recognise the dynamic, interactive, contested, and negotiated nature of local knowledge. Such local knowledge saves lives by enabling responders to situate ad hoc, one-off events such as disasters in the broader and deeper context of community relationships, thereby providing more appropriate and more effective aid.

Quantifying social capital creation in post-disaster recovery aid in Indonesia: methodological innovation by an AI-based language model.

Smooth interaction with a disaster-affected community can create and strengthen its social capital, leading to greater effectiveness in the provision of successful post-disaster recovery aid. To understand the relationship between the types of interaction, the strength of social capital generated, and the provision of successful post-disaster recovery aid, intricate ethnographic qualitative research is required, but it is likely to remain illustrative because it is based, at least to some degree, on the researcher's intuition. This paper thus offers an innovative research method employing a quantitative artificial intelligence (AI)-based language model, which allows researchers to re-examine data, thereby validating the findings of the qualitative research, and to glean additional insights that might otherwise have been missed.

Islamic faith-based organisations and their role in building social capital for post-disaster recovery in Indonesia.

This paper investigates the role of Islamic faith-based organisations (FBOs) in Indonesia and examines the way in which their disaster recovery aid can be successful or less successful depending on social capital formation in communities affected by a disaster. The paper argues that Islamic FBOs play a prominent role in disaster-affected communities by building new social capital or strengthening existing social capital. Failure to do so may affect a community's recovery and its long-term resilience.

Air-Processable Perovskite Solar Cells by Hexamine Molecule Phase Stabilization.

Perovskite solar cells have emerged as a potential energy alternative due to their low cost of fabrication and high power conversion efficiency. Unfortunately, their poor ambient stability has critically limited their industrialization and application in real environmental conditions. Here, we show that by introducing hexamine molecules into the perovskite lattice, we can enhance the photoactive phase stability, enabling high-performance and air-processable perovskite solar cells.

DNA barcoding detects resurrected taxon (Sauvage 1880) in Sulawesi, Indonesia: Bolano Sau Lake phylogeny, phenotypic characters and implications for spp. conservation.

: The freshwater ichthyofauna of Wallacea is diverse and understudied. A baseline survey of Bolano Sau Lake in Parigi Moutong District, Central Sulawesi Province, Indonesia in 2019 found an eleotrid goby (local name payangka) with characters conforming to the genus , long considered monophyletic as but recently found to comprise at least eight species. This study focused on the molecular (DNA barcoding) identification and phenotypic characters of the payangka.

Antioxidant Activity of Usnic Acid Compound from Methanol Extract of Lichen Usnea sp.

Lichen Usnea sp. is one of the sources of natural bioactive compounds which are currently being developed as medicinal ingredients. The purpose of this study was the isolation and identification of secondary metabolites from methanol extract, toxicity test and antioxidant activity of Usnea sp.

Formation of Ultimate Thin 2D Crystal of Pt in the Presence of Hexamethylenetetramine.

Platinum naturally crystalizes into a three-dimensional crystal due to its highly symmetrical fcc lattice, with a metallic bond which is non-directional and highly isotropic. This inherently means ultimately that 2D crystals of a few atoms thick growth are hardly available in this material. Here, we discovered that a combinative effect of formic acid reductant and hexamethylenetetramine surfactant during the reduction of their metal ions precursor can realize an ultimate thin 2D crystal growth in platinum.

Highly Synergistic Sensor of Graphene Electrode Functionalized with Rutile TiO Microstructures to Detect L-Tryptophan Compound.

Spatial analysis of COVID-19 outbreak to assess the effectiveness of social restriction policy in dealing with the pandemic in Jakarta.

Coronavirus disease 2019 (COVID-19) has been spread globally and brought health and socioeconomic issues. Jakarta tried to accommodate health and economic interests through the Large-Scale Social Restriction (LSSR) policy that should be assessed. This study aims to (1) visualize the spatial patterns of confirmed Covid-19 cases and the locations of potential risk of transmission, and (2) determine the spatial processes underlying the spatial patterns of Covid-19 cases.

Effectiveness of Green Chemical Solvent-based on Triethylammonium Methanesulfonate Ion Liquid for the OPEFB Pretreatment Process.

Many studies have explored the pretreatment of lignocellulosic biomass based on oil palm empty fruit bunch (OPEFB) which is categorized as potential biomass waste for bioethanol production. Before proceeding further to obtain bioethanol, several steps such as pretreatment to increase organic constituents are needed. The ionic liquids (ILs) were commonly investigated by many researchers for lignocellulosic pretreatment because it is easy solubilization property, non-toxic, and not harmful impacts on the environment.

Facilitators and Barriers to the Implementation of Preschool Oral Healthcare Programme in Malaysia from the Perspective of Dental Therapists: A Qualitative Study.

The Preschool Oral Healthcare Programme (POHP) was introduced in Malaysia by the Ministry of Health in 1984 to provide oral healthcare for 5-6-year-old children. Most of its evaluations were directed towards assessing children's oral health status. Little emphasis has been placed on assessing the programme feasibility from the perspectives of the oral health personnel.

Hierarchical Bimetallic AgPt Nanoferns as High-Performance Catalysts for Selective Acetone Hydrogenation to Isopropanol.

A combinative effect of two or more individual material properties, such as lattice parameters and chemical properties, has been well-known to generate novel nanomaterials with special crystal growth behavior and physico-chemical performance. This paper reports unusually high catalytic performance of AgPt nanoferns in the hydrogenation reaction of acetone conversion to isopropanol, which is several orders higher compared to the performance shown by pristine Pt nanocatalysts or other metals and metal-metal oxide hybrid catalyst systems. It has been demonstrated that the combinative effect during the bimetallisation of Ag and Pt produced nanostructures with a highly anisotropic morphology, i.
