The development of an increasingly fast and instant era in this millennial era, makes electronic devices, especially laptops, also experience very fast and extensive development. The capacity of a ...laptop is closely related to the price of a laptop, if the capacity of the laptop is higher, the price of the laptop will also be higher, and vice versa if the capacity of the laptop is lower, the price of the laptop will also be lower. each laptop offers different features of each type and gives each type a unique look and shape. This is what makes students and the public confused about which laptop to choose according to their wishes and the money budget they have so that they don't make the wrong choice in determining the type of laptop that students and the community want later. On this basis, a study was made that is used in making decisions on laptop selection using the Analytical Hierarchy Process (AHP) method. This research was conducted to find out how the decision support system in choosing a laptop that suits the needs and economic conditions for students and the community.
This study aims to explore the interactions between the government, the tourism industry, universities, media, society, and the environment in the management and utilization of tourist villages in ...Bandung Regency, Indonesia. The research employed a qualitative-explorative method with a case study approach. Research analysis was assisted by the Nvivo 12 Plus qualitative analysis tool. The result's findings show that tourist villages require coordinated efforts from the government, tourism sector, universities, media, local communities, and the environment because in our opinion the environment/nature cannot only be viewed as an object but must rather be aligned with other important sectors in development programs. This connection may at the very least provide a means of enhancing the management of tourism villages and achieving sustainability and resilience. The contribution of this research provides insight into the process of developing creative tourism villages in realizing sustainability and resilience through tourism villages that pay attention to economic, social, infrastructure, and environmental dimensions.
The problem of ultrafine particles (UFPs; PM0.1) has been prevalent since the past decades. In addition to become easily inhaled by human respiratory system due to their ultrafine diameter (<100 nm), ...ambient UFPs possess various physicochemical properties which make it more toxic. These properties vary based on the emission source profile. The current development of UFPs studies is hindered by the problem of expensive instruments and the inexistence of standardized measurement method. This review provides detailed insights on ambient UFPs sources, physicochemical properties, measurements, and estimation models development. Implications on health impacts due to short-term and long-term exposure of ambient UFPs are also presented alongside the development progress of potentially low-cost UFPs sensors which can be used for future UFPs studies references. Current challenge and future outlook of ambient UFPs research are also discussed in this review. Based on the review results, ambient UFPs may originate from primary and secondary sources which include anthropogenic and natural activities. In addition to that, it is confirmed from various chemical content analysis that UFPs carry heavy metals, PAHs, BCs which are toxic in its nature. Measurement of ambient UFPs may be performed through stationary and mobile methods for environmental profiling and exposure assessment purposes. UFPs PNC estimation model (LUR) developed from measurement data could be deployed to support future epidemiological study of ambient UFPs. Low-cost sensors such as bipolar ion and ionization sensor from common smoke detector device may be further developed as affordable instrument to monitor ambient UFPs. Recent studies indicate that short-term exposure of UFPs can be associated with HRV change and increased cardiopulmonary effects. On the other hand, long-term UFPs exposure have positive association with COPD, CVD, CHF, pre-term birth, asthma, and also acute myocardial infarction cases.

As a result of its carbon-dense structure and renewable nature, lignocellulosic biomass has emerged as a novel source for the production of graphene. At sufficient heat, biopolymers (cellulose, ...hemicellulose, and lignin) can be disintegrated into three-dimensional turbostratic crystallites, consisting of partially defective carbon sheets of aromatic rings (graphite-like material) via pyrolysis, where it may serve as a precursor in graphene synthesis. There are several techniques employed for graphene synthesis from lignocellulosic biomass; carbonization, graphitization, hydrothermal carbonization, chemical activation, chemical blowing technique, template-based confinement, mechanical and chemical exfoliation, and carbon growth via chemical vapor deposition. This review offers an insight into lignocellulosic biomass compositions and those aforementioned mechanisms to produce graphene-based materials, which cover various parameters and properties outcomes.

This article discusses islamophobia as a threat to multiculturalism in Indonesia. To test this assumption, this article uses the theory expressed by Huntington as a multicultural clash between ...Western civilization and Islam. The method used is qualitative-explorative with a phenomenological approach. By analysis using Nvivo 12 Pro Tools. The results of this study state that islamophobia has significantly undermined the harmonization of diversity in Indonesia. This is evidenced by the phenomenon of mutual disbelief among fellow Muslims and bigotry between Islamic groups in Indonesia. As an offer to face the threat of division from the high influence of islamophobia, it is to present Islam as rahmatan lil alamin to maintain national and state harmonization in Indonesia.
Fuels and fuel additives from furfural derivatives via etherification are reviewed. Etherification is classified into two methods such as reductive etherification and direct etherification. A ...previous study showed that ethers containing shorter alkyl chains increase the octane number of fuels. Ethers containing longer alkyl chains enhanced the cetane number of diesel fuel. The etherification of furfural and its derivatives hold particular promise for the production of fuel additives. There are two strategies to produce furanic ethers: (1) the conversion of furfural to furfuryl alcohol or acetal followed by etherification and (2) the etherification of furfuryl alcohol (FFA), occasionally known as direct etherification. Both strategies require an acid catalyst. The conversion of furfuryl alcohol to furfuryl ethers was influenced by Brønsted or Lewis acid. The synthesis of methylfurans, which has higher research octane number than gasoline, is also described.
