Photochemical solution-phase reactions have been widely applied for the syntheses of nanocrystals. In particular, tuning of the nucleation and growth of solids has been a major area of focus. Here we ...demonstrate a facile approach to generate atomically dispersed platinum via photochemical reduction of frozen chloroplatinic acid solution using ultraviolet light. Using this iced-photochemical reduction, the aggregation of atoms is prevented, and single atoms are successfully stabilized. The platinum atoms are deposited on various substrates, including mesoporous carbon, graphene, carbon nanotubes, titanium dioxide nanoparticles, and zinc oxide nanowires. The atomically dispersed platinum on mesoporous carbon exhibits efficient catalytic activity for the electrochemical hydrogen evolution reaction, with an overpotential of only 65 mV at a current density of 100 mA cm
and long-time durability (>10 h), superior to state-of-the-art platinum/carbon. This iced-photochemical reduction may be extended to other single atoms, for example gold and silver, as demonstrated in this study.
Penggunaan smartphone yang canggih di dunia kerja kerap menimbulkan masalah seperti yang terjadi di PT. X dimana seorang pekerjanya yaitu Ibu A pada awal tahun 2022 lalu dipaksa untuk memberikan ...smartphone-nya untuk digeledah atas perintah dari Direktur PT.X yaitu Ibu B. Perintah penggeledahan itu muncul seiring dugaan ujaran kebencian yang diutarakan oleh Ibu A tentang Ibu B ke sesama pekerja melalui pesan singkat Whatsapp. Penulisan artikel ini bertujuan untuk menjawab pertanyaan besar apakah perusahaan berwenang untuk memeriksa ponsel pegawainya ditinjau dari hukum positif di Indonesia yaitu Undang-Undang ITE. Penulisan artikel ini menggunakan metode yuridis normatif dogmatik dengan melakukan pendekatan melalui peraturan perundang-undangan (statutes approach) dan pendekatan konsep. Hasil akhir dari penulisan ini adalah bahwa Smartphone milik Ibu A adalah milik pribadi Ibu A dimana seluruh data yang ada didalam ponsel itu adalah milik pribadi yang dilindungi oleh Pasal 26 ayat (1) UU ITE jo Pasal 30 ayat (1) UU ITE sementara Ibu B selaku Direktur PT. X dapat melakukan penggeledahan karena Ibu B tidak tergolong sebagai penyidik sebagaimana telah dijelaskan dalam Pasal 43 UU ITE.
It has been recorded so far that the earthquake in Indonesia has damaged many publicfacilities and claimed many victims. Most cases of casualties were not caused directly by the earthquake but as a ...result of falling debris from buildings that were unable to respond to the earthquake. To avoid similar incidents in the future, all buildingsin Indonesia need to be inspected and ensured that they are safe from the threat of an earthquake, and school buildings are no exception. The absence of a specific assessment tool for earthquake-resistant school buildings underlies this research. The assessment tool was developed based on the results of a literature review of several building inspection standards in various countries. Several research variables that were previously identified were then validated and processed using the Analytical Hierarchy Process method. Some experts in related fields were involved in the process to formulate the significant variables, the respective weights as well as scoring systems. This research produced a preliminary assessment tool in two parts. The first one, which emphasizes examination by visual method, is translated into four new categories: Building Slope Inspection, Sub-structure Component Inspection, Upper Structure Component Inspection, and Document Inspection, with 12 sub-categories and 28 indicators. Meanwhile, the second part emphasizes on the non-destructive testing as additional scores. It includes three types of tests for concrete and two tests for steel materials. Finally, the level of preparedness for the structural components of a good school building needs to meet a minimum score of 70.
This research paper discusses the Child labor protection law, specifically in culinary business. The Author raises a phenomenon regarding a Child with initials JS who built Tang Kitchen culinary ...business along with his brother in Surabaya. Research method used is a Normative Juridical method, that processes legal material collected through literature review.
This study aims to discover applicable law (legal protection) towards Children working in culinary business, particularly based on Act No. 13 year 2003 concerning Employment, Art No. 23 year 2002 concerning Children Protection and Art No. 35 year 2014 regarding Amendment of Art No. 23 year 2002 concerning Children Protection (Art No. 35 year 2014).
The research result shows that JS and his Brother who are still classified as Children, have received a protection from Indonesian applicable law protection based on Article 69 and 71 of Act No. 13 year 2003 regarding Employment. Moreover, JS’ job in Tang Kitchen culinary is not considered as a job that endangers Children as regulated under KEPMENAKERTRANS 235/2003, and has complied with JS’ talents and interests as regulated under KEPMENAKERTRANS 115/2004.
Money Laundering Crime as a further criminal act has placed and involved two main perpetrators, namely active actors as parties trying to hide or disguise the origin of assets that are the result of ...criminal acts in various ways, and passive actors as parties who receive Money Laundering Crime assets. The return of Money Laundering Crime assets is not only through coercive measures, but also requires a voluntary return by the receiving party. In practice, voluntary returns create uncertainty when the receiving party (passive actor) from the beginning does not know the origin of the assets received. Through various money laundering cases in Indonesia in June-July 2022, the Authors are very interested in analyzing the extent of obligations related to the return of Money Laundering Crime assets. This research uses normative juridical methodology with Law approach and concept approach. The purpose of this study is to determine the obligations that must be carried out by passive trafficking actors based on Law No. 8 of 2010.
Traffic accident often happens and involved underage child as driver of the vehicle and might lead to fatal consequences, such as the death casualities. In Indonesia, it is stipulated in Act No. 22 ...Year 2009 concerning Traffic and Road Transportation. The result shows that M’s illegal underage driving caused the death of K. Thus, M and his family are obliged to give compensation to the K’s family as stipulated in of Act No. 22 Year 2009 throughout Juvenile Justice System as the case procedur using Diversion case is stipulated in Act No. 11 Year 2012 regarding Juvenile Justice System
•We measured structural complexity in a biodiversity enrichment experiment in oil palm.•Mixed-species tree planting rapidly enhanced structural complexity.•Species identity was a strong driver of ...structural complexity–diversity relationship.•Structural complexity of mixed-species plots remains much lower than that of forests.
Conversion of structurally complex rainforests into simplified oil palm monocultures leads to dramatic losses of biodiversity and ecosystem functioning. To alleviate negative ecological impacts, enrichment with native tree species may rapidly restore structural complexity in existing oil palm plantations. However, the mechanisms underlying the recovery of structural complexity in mixed-species tree plantings remain poorly understood. We measured structural complexity from terrestrial laser scanning in a biodiversity enrichment experiment with multiple tree species planted in an oil palm monoculture, forming agroforestry plots of varying tree species diversity and plot size. We find that three years after tree planting, structural complexity in oil palm increased by one third, representing 25% of the increase needed to restore the structural complexity of tropical forests. Changes in structural complexity were associated with denser and more complex filling of three-dimensional space, whereas vertical stratification was mainly influenced by oil palm. Furthermore, structural complexity increased with tree species diversity in the agroforestry plots. This relationship was mainly due the presence of well-performing species that contributed to higher levels of structural complexity. However, interactions among multiple species independently from the species identity were also detected. Finally, increasing plot size had a positive effect on a scale-independent measure of structural complexity. Our results provide evidence that planting multiple tree species in large agroforestry plots is a suitable strategy to rapidly enhance structural complexity in oil palm plantations.
