Polarization entanglement holds significant importance for photonic quantum technologies. Recently emerging subwavelength nonlinear quantum light sources, e.g., GaP and LiNbO3 thin films, benefiting from the relaxed phase-matching constraints and volume confinement, has shown intriguing properties, such as high-dimensional hyperentanglement and robust entanglement anti-degradation. Van der Waals (vdW) NbOCl2 crystal, renowned for its superior optical nonlinearities, has emerged as one of ideal candidates for ultrathin quantum light sources [Nature 613, 53 (2023)]. However, polarization-entanglement is inaccessible in NbOCl2 crystal due to its unfavorable nonlinear susceptibility tensor. Here, by leveraging the twist-stacking degree of freedom inherently in vdW systems, we showcase the preparation of tunable polarization entanglement and quantum Bell states. Our work not only provides a new and tunable polarization-entangled vdW photon-pair source, but also introduces a new knob in engineering the entanglement state of quantum light at the nanoscale. © 2024, CC BY-NC-ND.

Indonesian government through National Medium Development Term Plan (2015-2019) aims 100% easy access of clean and fresh drink water, and 100% decent access of sanitation. The present study aims to determine index risk of sanitation modeling (IRS) of domestic waste water as an effort in achieving the target of Universal Access 2020. Discriminants that resulted from the present study are: Z1 = -41.86 - (1,16*IRS) + (0,07*PM) + (0,16*PP) + (0,11*PWM) dan Z2 = 6.74 + (1,54*IRS) + (0,01*PM) + (0,21*PP) - (0,26*PWM) in which it is used to determine domestic waste water system. Variables that influence this system are index risk of sanitation (IRS), female participant (PP), poor people (PWM), and beneficiary (PM). When the equation mentioned above is applied into 154 districts in Surabaya, the result will be as follow: 1) Based on Domestic Waste Water System there are 57 districts (37,01%) that can be included into communal system, 31 (20,13%) districts are included into domestic IPAL system and 66 districts (42,86%) are included into combination between communal and IPAL system. © Published under licence by IOP Publishing Ltd.

The research aims at developing a learning video to make shredded chicken and testing its feasibility. This video demonstrates the steps of product making. This research can be categorized as research and development (R&D) with a 4D model (Define, Design, Develop, and Disseminate). The video was taken with multiple camera angles and completed with text annotation, picture, animation, music, and voice lay-over. The were collected through interviews and questionnaires for feasibility testing. The data were analyzed using quantitative descriptive analysis. The stage of define was a needs analysis, while the design stage consisted of testing recipes, scriptwriting, selection of presenters, talents, dubber, and the video team and preparing tools and materials. The develop stage covered the process of shooting, recording, editing, and feasibility test by two material experts and a media expert. Meanwhile, the disseminate stage referred to the feasibility test among 30 students of State Vocational High School 1 Cangkringan, and the video dissemination was done through the YouTube channel. The feasibility test result based on the material experts was 90.96%, based on the media expert was 98.96%, and from the students was 85.35%, respectively.

In diffraction experiments, natural gratings often create uncommon diffraction patterns compared with those resulting from manufactured gratings. This study analyzed a unique diffraction pattern obtained by a grating from a flying termite wing. A ring-like diffraction pattern was formed because of the grating morphology from a flying termite wing, which consisted of horizontal- and vertical-structured slits. The mechanism of diffraction pattern formation is also provided. The distance between slits was measured using digital microscope images and a diffraction experiment, with the results coming to an agreement. Using this grating in a diffraction experiment can help educators provide an alternative diffraction experiment that supports students in studying the topic in a more complex manner. © 2022 IOP Publishing Ltd.

Multi-perspective review on application of self-healing concrete and its prospect in Asia

Concrete is the most popular material construction which can be applied in broad construction projects. In addition, concrete is also featured with robust strength, durability, reflectivity, and versatility. However, concrete is prone to rupture that results in decreasing life span and its quality, so it requires additional cost for repair toward its damage. Self-healing concrete is one of the innovations developed by researchers to solve the cracks in concrete allowing the concrete to recover the cracks through the healing process. A self-healing concrete has more superior mechanical properties compared with normal concrete. Self-healing mechanisms can be divided into two types: autogenic and autonomic self-healing. Autogenic self-healing takes advantage of the formation of calcium carbonate crystals from unhydrated cement or mineral particles. Meanwhile, autonomic self-healing uses a healing agent capsulized into microvascular, microencapsulation, and pallets. Researchers applied self-healing concrete on a macro-scale, such as in panel walls, roof slabs, and river floodgates. This paper uses the literature review method to collect the data about self-healing concrete. This study aims to discuss self-healing concrete, its mechanical properties, durability, and analysis of the use of self-healing concrete from multi-perspective disciplines including economy, health and environment, construction, and public policy in Asia’s countries.

Whiteboard animation videos are engaging learning media for Generation Z. This study aimed to develop and assess the feasibility of a whiteboard animation video for vitamin in the Nutrition science subject for class X culinary vocational school. This study was research and development using a 4D approach (define, design, develop, disseminate). The define stage analyzed the curriculum, material, student character, learning media, and school facilities. The design stage included the writing and assessing the material, the writing and assessing of storyboards, and production team selection. The develop stage was making a video and assessing the feasibility. Animation images were created using Paint Tool Sai. Image conversion from JPEG to SVG was performed with Inkscape. The dubber's voice was recorded with Universal Audio using the Apollo Twin audio interface and Avantone CV12 microphone. The audio was edited in Pro Tools 2020.9. To produce a whiteboard animation video, animation images, captions, dubber's voice, and back sound were combined with VideoScribe. Videos used mpg format. In order to maintain video duration below 10 minutes, the video was divided into two parts. The assessment of video feasibility was carried out by one media expert and two content experts. The assessment of feasibility at the disseminate stage was carried out to 30 users. Based on the feasibility assessment, this video was very suitable to be applied as a learning medium.
