The systems entitled ’Nakula’ and ’Sadewa’ are designed in an integrated manner to meet the needs of the distribution and promotion process of student work. There are three main needs in managing audio-visual works in the broadcasting study program: (1) The need for a work archive system. (2) Open access to works for students as a learning medium. (3) Showcase student work so that it can be accessed on a limited basis by stakeholders or sponsors. These findings can complement the findings of previous studies which have been able to use the E-portfolio system as a promotional medium and the E-Catalog as a student learning medium. These two systems are then combined into an integrated system that can answer the three main needs for the distribution and archiving of works in the broadcasting study program. The method used in this research is the development research method (DRM). This method tries to map the problem at a locus and find a solution based on the problem found. Apart from that DRM also prioritizes the involvement of each actor in these activities so that it can maximize the role of each actor. The findings in this article are a platform called Nakula-Sadewa, which has features including a showcase of student assignments that can be accessed in full version for polymedia students so that it can be maximized as a learning medium, limited access by sponsors or external parties, work archive facilities, and writing practice for students. \u0000Keywords: Nakula-Sadewa, promotion, learing, media, platform","PeriodicalId":106635,"journal":{"name":"KnE Engineering","volume":"12 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140258941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Instilling conception from an early age in children regarding reproductive health education, which is still taboo in most Indonesian societies, is an indication of research achievements that are relevant to be applied in social sciences and humanity. This research aims to test the feasibility of the pop-up book with the title “Yours” (Reproductive Health Education Book) for the age group of children over 6 years. The research method applied in this study is the research and development (R&D) method with the 4D flow (define, design, development, and dissemination). The pop-up book product with the title Pop Up Yours is a product created by the author and has never been tested for feasibility before. The results showed that the Pop Up Book “Yours” can be a medium for reproductive health education in children with the results of testing on 30 children(n=30) aged 9 years, an increase in knowledge of 93.3% was observed. Based on the results of the feasibility test, it can be seen that the “Yours” Pop Up Book is suitable for use by groups of children over 6 years old with the important concern of using this pop-up book under parental guidance. \u0000Keywords: pop-up book, child, reproductive health","PeriodicalId":106635,"journal":{"name":"KnE Engineering","volume":"42 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140259263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is common practice for individuals to store money (angpau) in the peci for easy access, however, there is a problem with the existing traditional peci design. Money will scatter when the peci falls off, thus, compromising user comfort and safety. The peci design was explored by introducing an additional wallet feature with a zipper that allows customization and versatility. Additionally, the use of Betawi traditional ornaments further enhances the peci value, making it suitable as an iconic souvenir from Jakarta. This research applied the design thinking approach of the Hasso Platner Institute (HPI) Stanford model with five steps comprised of empathize, define, ideate, prototype, and test as a problem-solving tool to provide a better understanding of the needs and perspectives of peci users. The results show that pecipaw innovation could cater to the added value of traditional peci products as an iconic souvenir of Jakarta.

The direct synthesis approach is preferred to provide the environmentally friendly production of H2O2 for market requirements. Bimetallic PdNi nanocatalysts were chosen for this study because of their catalytic activity and the structural characteristics of the material system. First, for the development of order-structured bimetallic PdNi nanocatalysts based on mesoporous carbon template after hydrogen-assisted heat treatment at 750∘C. The transformation of the disordered structure into ordered intermetallically structured PdNi alloys with higher alloying extents was confirmed by X-ray absorption spectroscopy (XAS) and high-resolution transition electron microscopy (HR-TEM). Then, to improve the oxygen oxidation reaction, two-electron pathway selectivity was used by TiO2-C as a support-ordered structure material to facilitate strong metal-support interactions. XAS and X-ray photoelectron spectra (XPS) techniques show more clear evidence of metal-support interactions with electron transfer from defects in the TiO2-C support to the ordered alloyed PdNi nanocatalysts, resulting in record productivity and selectivity of H2O2 production at ambient conditions. The results demonstrated in this study will enlighten a reliable design of new heterogeneous nanocatalysts with ordered structure. Electron transfer between hybrid support and active sites can clarify the catalytic behavior and prompt further research during the direct synthesis of hydrogen peroxide. \u0000Keywords: hydrogen peroxide, direct synthesis, heterogeneous nanocatalysts PdNi, TiO2-C","PeriodicalId":106635,"journal":{"name":"KnE Engineering","volume":"2 27","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140258589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, the catalyst used in the production of the material plays a key role leading to intensive research. Synthesis of nanomaterials is becoming an important way to discover new catalysts by changing sizes and combining two or more metals on the nanoscale. Pd-based catalysts are well-known catalysts such as Pd-Pt, Pd-H, and Pd-Au for many chemical reactions such as the direct synthesis of hydrogen peroxide. Therefore, the provision of nanocluster bimetallic catalysts offers more benefits such as the rearrangement of surfaces to suit characteristics and lower material costs. However, the stability of the catalyst challenges researchers beyond reactivity and selectivity. In this paper, we predict the structural stability of Pd-based catalysts using a density functional theory approach. We use the 38-atom model in the M6@Pd32 core shell, where M is Hg, Pt, Au, Cu, Ni, Cu, Zn, Ag, Pd, and Cd, Pt. We prepared and investigated a series of structures such as truncated octahedral (TO) and polyhedral (PH) by calculating the excess energy. Based on our calculations and placing the monometallic Pd38 nanocluster as a reference, the TO structure is more stable than that of PH. The Zn6@Pd32 system showed the most stable followed by Cd6@Pd32 and Hg6@Pd32 was the worst. \u0000Keywords: structural stability, core-shell, nanocluster, Pd-based catalyst","PeriodicalId":106635,"journal":{"name":"KnE Engineering","volume":"33 16","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140260390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
