Housing is a set of houses that are established with different functions for the owner with equipped infrastructure that is equipped according to the owner wishes. In determining the location of housing in Pringsewu district, the criteria were needed in accordance with the consumer’s wish. This study will be explained on how to determine the location of housing in Pringsewu district using weighted product method. Because the weighted product method can help decision making in determining the location of housing, the calculation only resulted the greatest value that will be chosen as the best alternative.

Shape Memory Polymers (SMPs) have emerged as adaptable and promising biomaterials in biomedical engineering, enabling innovative solutions for minimally invasive procedures and personalized therapies. This review presents a comprehensive overview of SMPs, focusing on their unique shape memory effects, tuneable material properties, and emerging biomedical applications. Unlike previous reviews that primarily focused on performance enhancement through conductive fillers or crosslinking strategies, this work highlights both the tailored modification of SMP characteristics and their functional integration within biomedical contexts. Key SMP types, such as poly(lactic acid), polycaprolactone, polyurethane, poly(methyl methacrylate) and bile acid-based polymers are critically evaluated with respect to their biocompatibility, biodegradability, and responsiveness to external stimuli. Moreover, biomedical applications such as controlled drug delivery, vascular stenting, dental devices, and tissue engineering are also discussed, with particular attention to recent advances and persisting challenges. Furthermore, the review identifies essential considerations for SMP selection, including mechanical robustness, physiological compatibility, and regulatory requirements. By synthesizing current developments and outlining emerging research directions, this article provides a framework to guide both researchers and clinicians in leveraging the full potential of SMPs for next-generation biomedical devices and therapeutic platforms.

Chili is a high value vegetable commodity. Because there are still many people who do not understand the type of superior chili plant. Because all this time the community determines the superior chili plants only by guessing, because of that, it was developed a Decision Support System which was used to determine the superior chili plant. Sample (alternative) of this research were 3 types of chili plant, namely cayenne curly chili, large chili. While the criteria used were plant age, plant height, leaf conditions, number of leaves and the results obtained from this study large chili plants are the highest ranked. The method used in determining the superior chili was Simple Additive Weighting (SAW), and the construction of Decision Support System (DSS) to determine superior chili plant using the Delphi 7 application program.

Nitrogen-doped graphene aerogels (NGAs) have attracted much attention as next-generation electrode materials for supercapacitors because of their high surface area, excellent conductivity, and chemical tunability. Recent studies have confirmed how nitrogen doping can improve pseudocapacitive behaviour, wettability, and electron transport, thus significantly improving the specific capacitance, energy density, and cycling performance. This review analyses the different synthesis strategies, such as hydrothermal self-assembly, sol-gel polymerisation, and template-directed synthesis, and shows the electrochemical performance obtained from both symmetric and asymmetric set-ups. The best-performing NGAs have demonstrated specific capacitances reaching 900 F/g, energy densities of over 60 Wh/kg, and long-term retention exceeding 90% over 10,000 cycles. Nonetheless, multiple synthesis strategies are still limited by batch processing, excessive thermal demand, and difficulty with dopant homogeneity. Details on the electrode configuration and performance reported between studies are inconsistent, making direct comparisons challenging and hindering industrial translation. This review highlights the critical demand for scalable, greener synthesis protocols, standardised testing protocols, and systematic evaluations of the role of nitrogen species in capacitance enhancement. This work can be extended to dual-doping, flexible electrode fabrication, and the incorporation of the doped material into practical device architectures. Such insights provide a basis for rationally designing high-performance N-GAs for supercapacitors.

Per- and polyfluoroalkyl substances (PFAS) persist in aquatic environments and resist conventional wastewater treatment, thereby sustaining long-term exposure risks. However, decision-making is hindered by uneven global monitoring, especially in Southeast Asia, along with method-dependent variations in occurrence or removal estimates, and limited pilot-scale evidence for truly destructive yet cost-credible treatments. This review synthesises global occurrence trends before and after major regulatory actions and compares reported removals across wastewater treatment plants (WWTPs), highlighting geographic variability, gaps in treatment efficiencies and method-dependent results. It also examines the health and environmental threats associated with legacy PFAS and their emerging alternatives when inadequately treated. Current PFAS remediation options (i.e., physical adsorption, membrane treatment, advanced oxidation processes (AOPs), and photocatalysis), are benchmarked against practical criteria (i.e., efficiencies, limitations, stability and cost). Particular attention is given to the advantages and challenges of photocatalytic technologies. In particular, membrane technology can considerably improve photocatalytic treatment. Photocatalytic membrane techniques may improve catalyst stability, reusability, and degradation yield. By reducing energy and secondary-waste burdens through catalyst reuse, photocatalytic membranes may be cost-credible. Their scalability depends on durable immobilisation, fouling control, and straightforward integration with current infrastructure. Therefore, these considerations highlight the necessity to investigate and enhance photocatalytic membrane systems for effective and sustainable PFAS remediation.
