In recent years, the International Working Group led by the Islamic Research and Training Institute has developed guidelines known as the Zakat Core Principles for effective Zakat supervision. While these efforts represent significant progress and are widely adopted in the Islamic world, we argue that the efforts miss a key piece of the cultural and moral normative frameworks by not examining how Muslim public's support could influence the effectiveness of alternative supervision methods. In environments where transparency and disclosure are prioritised, these cultural and moral norms play a crucial role in differentiating between legitimate and illegitimate zakat transactions. However, the International Working Group primarily emphasises financial reporting and institutional development, which often overlook these cultural and moral dimensions essential for effective zakat supervision. This article draws insights from international practices, such as the Islamic Bank of Thailand's zakat account, where funds are managed within Islamic financial institutions under stringent supervision, and the Lembaga Zakat Negeri Kedah's approach to risk management and public accountability. It argues for adopting an integrated approach that incorporates normative and cultural dimensions, aligned with Indonesia's religious and social contexts, for a more comprehensive zakat supervision and fund management strategy. This approach will not only improve the efficiency of zakat distribution but also enhance public trust in zakat institutions, leading to increased zakat collection and a greater positive impact on those in need.

This study contributes to understanding ecological changes in land use following slash-and-burn land clearing. This study aimed to compare the richness and density of plant species and soil fertility in farmland cultivated for one year (1 Y), three years (3 Y), and five years (5 Y) after slash-andburn, with the conditions in the secondary forest (SF) in Berau Regency of East Kalimantan. Understory plant taxon types, numbers, and soil organic matter were measured in each region using a series of nested plots. The size of each observation plot was 20 x 100 m. Data on understory vegetation composition was collected using 1 x 1 m mini plots at 20 sampling points and divided into five blocks, with a 10 m spacing between sampling points on each property. Understory vegetation species and cover percentage, litter cover percentage, open soil percentage, and soil fertility were measured for each observation plot. The results showed that the land cover percentage increased each year during the 5 years transition from secondary forest to farmland. Furthermore, within the 5 years, there was a change in understory species, particularly the presence of grasses and sedges at 3 and 5 years after the land use change. However, the transition from secondary forest to farmland within 5 years did not alter soil organic matter and total nitrogen. [ABSTRACT FROM AUTHOR]

Justice Collaborator aims to facilitate evidence and prosecution as well as fully reveal a crime, especially those related to organized crime. However, not everyone who commits a crime as a perpetrator wants to become a justice collaborator for various reasons, including a lack of legal protection. The formulation of the problem is 1. What is the legal protection for justice collaborators in narcotics crimes so far? 2. What is the ideal concept of legal protection for justice collaborators in the criminal justice process, especially narcotics, in the future? This research uses a type of normative research with statutory, comparative and conceptual approaches. The research results show that in Indonesia, only a few perpetrators of narcotics crimes are willing to become justice collaborators, one of the reasons is the lack of legal protection. The ideal concept of legal protection for justice collaborators in the criminal justice process, especially narcotics, in the future is carried out by reconstructing regulations regarding justice collaborators. Reconstruction can be carried out using two alternatives, namely: reconstructing the Witness and Victim Protection Law, or creating separate regulations regarding justice collaborators in the form of a law.

The purpose of this study is to examine the effect of religiosity and customer trust on brand loyalty among Generation Z (Muslim consumers in Indonesia), during a particular timeframe (post-Israeli-Palestinian conflict), thereby adding nuanced insights to consumer behavior research in a globalized context. The study is located in Cirebon, Indonesia, with research subjects namely consumers who buy products from McDonald's and people who follow the issue of boycotting Israeli products from the Palestinian conflict among FEB Management students of Universitas Swadaya Gunung Jati. The results of the fit model test show that religious values and consumer trust significantly impact McDonald's brand loyalty in the Z generation. Consumer trust has a positive and significant effect on Brand loyalty (Z), with the remaining (1 - 0.505) = 0.495 (49.5%), which is influenced by other variables not determined by the model. This research contributes by bridging the gap between religious values, consumer trust, and brand loyalty, in the post-israeli conflict Z generation (Generation Z, Muslims in Indonesia). The study suggests strengthening the involvement of consumers through social media and promotional events, while also considering the importance of religious beliefs in decision-making.

Biodiesel, an alternative to traditional diesel, is essential for the sustainability of long-term energy supplies and often synthesized through a non-alcoholic route called interesterification. The described synthesis method facilitates the modification of oil and fat by exchanging acyl radical groups between triglyceride and alcoholic acid (alcoholysis), fat (acidolysis), or ester (transesterification). Therefore, this research aimed to determine the effect of the reactant ratio between crude palm oil (CPO) and dimethyl carbonate (DMC), along with the use of an eco-enzyme catalyst, on biodiesel characteristics. The CPO:DMC ratio was 1:1.5, 1:2, 1:2.5, and 1:3, while the immobilized eco-enzyme catalyst was 2%, 3%, 4%, 5%, and 6% of CPO mass. The results showed that interesterification with a 1:3 reactant ratio using a 4%wt catalyst was the best procedure, producing biodiesel yield of 73.65%, density of 0.860 g/mL, viscosity of 4.63 mm2/s (cSt), flash point of 113 °C, calorific value of 34.454 MJ/kg, and cetane number of 70.6%.

In Second Language Writing class, the use of student-based assessment such as self and peer assessments has been increasingly promoted in addition to the teacher-assessment (Alias, Masek, & Salleh, 2015; Chang, Tseng, & Lou, 2012; Esfandiari & Myford, 2013) to help the students make a good writing product (Andrade, Du, & Mycek, 2010). Nevertheless, the inclusion of the student-based assessment result in determining the students’ final score still becomes a controversial matter since some studies prove that the student-based assessment and teacher assessment are not in agreement and tend to be questionable (Alias et al., 2015; Panadero, Romero, & Strijbos, 2013). Therefore, to bridge the gap, this study aims at investigating the level of consistency among self-assessment, peer assessment, and teacher assessment in a writing course. Through a correlational research design, the current study involved 21 students who took a paragraph writing course and experienced in self and peer assessing. To collect the data, the students were asked to write an expository paragraph that was assessed through self, peer and teacher assessments. After collecting the data, then the data analysis is done by using Spearman Rank Order Correlation to answer whether or not there is consistency among self-assessment, peer assessment, and instructor assessment. The results reveal that the students provided the same score in self, peer and teacher assessment. However, the correlations in both self and peer-assessment, as well as self and teacher assessment, are not considered statistically significant. The significant difference occurs in the correlation between peer and teacher assessment result only. From this finding, it can be recommended to the teacher to include the result of peer assessment in determining the students' final grade.

Technology has a big and significant impact on everyone's life. This is due to the increasing development of technology from time to time and is supported by the internet. Until now, the internet has become a necessity for society, because the internet supports all community activities in terms of communication and information, and makes it easier for everyone, whether working, studying or carrying out other activities. In this case, ever-increasing progress means that everyone can take advantage of a situation that can be called digital technology. This allows advertising targeting to the general public which is very focused on communicating with each other, tracking potential buyers and engaging them in related content. Advances in communication and network technology, especially the internet, provide the infrastructure needed for businesses that are run using the internet. The very rapid development of computer and telecommunications technology (information technology) today has resulted in a revolution in the world of trade and industry. In this research, the author used a qualitative research method with a bibliometric approach. In this bibliometric approach there are four analyses, namely, co-authoring analysis, bibliometric network visualization analysis, overlay visualization analysis, and density visualization analysis. This provides an overview and a mapping to the reader regarding a preparation related to Digital Marketing Strategy. [ABSTRACT FROM AUTHOR]

People are becoming more aware of environmental difficulties in this time of globalization. Waste is one such problem, as waste is a major source of pollution in the air, soil and water. It is hoped that all individuals and businesses in Indonesia, including consumers, will increase awareness and concern for the environment as an effort to preserve and restore the earth's ecosystem. Emina products are one example of a company that prioritizes sustainability in its systems and products at PT Technology and Innovation. Emina is considered a product that contributes to a positive reputation and values social responsibility. Green marketing includes all efforts and endeavors directed at promoting, packaging, distributing, consuming, and recalling products through environmental awareness or response. Corporate social responsibility is a condition in which businesses must continue to pay attention to the environment in an effort to reduce environmental problems that have occurred or are occurring. To achieve sustainable growth and performance, corporate social responsibility is an initiative that is integrated into the investment strategy and is considered a corporate social obligation. Brand image, alongside environmental concerns and corporate social responsibility will emerge as an important consideration for companies in the coming years. Consequently, brand image is consumers' and customers' perception of a brand, which in turn inspires trust in the brand. This research highlights the importance of green marketing and environmental accountability in general by building a good perception of the organization's brand within the local community. The purpose of this study is to determine the correlation between brand image (Z) and the impact of corporate social responsibility (Y) and green marketing (X). Uncertainty surrounds most Emina product users who make up the population of this study. In the absence of population information, the sample size for a given study will be calculated based on criteria for an unknown population, resulting in a total of 100 respondents. This research will use a purposive sampling method, which involves selecting a sample from the population under study based on certain criteria. Regression analysis and path analysis will be used to analyze the data. Hypothesis testing, validity and reliability tests, normality and multicollinearity tests, path analysis model fit tests, and SPSS and AMOS Softwer analysis tools will be used for data analysis. According to the findings of this study, green marketing influences consumer perceptions of Emina products favorably, thereby contributing to improved environmental stewardship. Emina is perceived as an ethical and socially responsible entity, which positively impacts its reputation. [ABSTRACT FROM AUTHOR]

Creative spaces have become important places that encourage innovation, collaboration, and imagination in various fields. This study investigates the complex dynamics of creative spaces by studying physical, social, and psychological aspects. We do this from the perspective of different disciplines and designs and see how special characteristics and creative processes interact with each other. We investigate the influence of spatial confirmation, atmosphere, and accessibility on individual creativity and productivity in this setting using mixed methods, including qualitative case studies and quantitative analysis. Our results show that design components such as layout flexibility, natural lighting, and aesthetic appeal influence how people think and interact with others. All this forms a broad creative experience. In addition, this research investigates how organizational culture, leaders and community dynamics play a role in building and maintaining creative ecosystems in these places. By explaining the complex relationship between the physical environment and human behaviour our research offers insights for practitioners, policy makers, and educators who want to create better creative spaces for collaboration and innovation. Using the Visualization of Similarities (Vos Viewers) tool, this research uses qualitative and bibliometric techniques. Using Vos Viewers you can search 992 articles by entering keywords such as; creative space; digital space; customer experience; and metaverse reduction. The results of the analysis show scientific mapping and potential for future research regarding creative spaces as a new marketing world. These results can be used as recommendation variables for researchers conducting further research. [ABSTRACT FROM AUTHOR]

The accuracy of air quality detection is a crucial aspect influencing user trust and satisfaction with artificial intelligence (AI) based air quality detection applications. However, only a few studies have tested the effect of the accuracy of AI-based quality detection on users' acceptance and use of these applications. This study aims to fill this gap by addressing the impact of perceived accuracy on behavioral intention and behavior using the AIKU application. This research uses a quantitative approach with the online survey method, distributed in January 2023 - February 2023 to AIKU users. Valid data were 287 respondents from 317 who were received and analyzed using partial least squares structural equation modeling (PLS-SEM). This study uses a modified technology acceptance (TAM) model by adding perceived intelligence as a mediating variable between perceived accuracy and usefulness. The results showed that nine hypotheses were accepted from the 13 hypotheses proposed. The results section of hypothesis testing shows that the effect of perceived AIKU application accuracy on perceived usability and ease of use is insignificant. However, these influences indirectly affect the behavioral intentions and attitudes of users. Even if users do not perceive purity as an essential factor, the user's attitude towards the application is still positive. This study makes a theoretical contribution by developing the TAM model by incorporating variables of perceived accuracy and perceived intelligence relevant to the AI-based context.

The COVID-19 pandemic is a virus that is changing habits in human life worldwide. The COVID-19 outbreaks in Indonesia have forced educational activities such as teaching and learning to be conducted online. Teaching and learning activities using the online method are familiar, but the effectiveness of this method still needs to be investigated to be applied in all educational systems. This study used the predictive modeling of Recurrent Forecasting (RF) derived from Singular Spectrum Analysis (SSA) to know the online learning method's practicality on the student's academic performance. The fundamental notion of the predictive fusion model is to improve the effectiveness of several forms of forecast models in SSA by employing a fusion method of two parameters, a window length (L), and a number of leading components (r). This study used undergraduate students' grade point averages (GPA) from a public university in Indonesia through online classes during the COVID-19 epidemic. The experiments unveiled that a parameter of L = 14 (T/20) yielded the finest prediction using the RF-SSA model with a root mean square error (RMSE) value of 0.20. Such a finding signified the ability of the RF-SSA to project the students' academic performance according to the GPA for the forthcoming semester. Nonetheless, developing the RF-SSA algorithm for greater effectiveness is essential to acquiring more datasets, such as by gathering a bigger group of respondents from several Indonesian universities.

Fly ash waste is a by-product of coal burning at PLTU Nagan Raya, Aceh Province, Indonesia. Since 2017, the coal used is a mixture of 90% Kalimantan coal (sub-bituminous) and 10% local Nagan Raya coal (lignite) which is still young so that the mineral ash content is still high. Silica is among the interesting minerals to be extracted from fly ash, given its wide range of benefits. This paper describes the process of extracting silica from fly ash at the Aceh power plant through the leaching method using a chemical solution and heating for 2 and 4 hours at a temperature of 100°C. The difference in heat treatment aimed to study the changes in properties and obtain the best method in the silica extraction process. The effect of heat treatment on silica characteristics was studied based on X Ray Diffraction (XRD) test for phase identification, Scanning Electron Microscopy (SEM) test for morphological identification, Energy Dispersive X-Ray Spectroscopy (EDS) test for mineralogy element identification, Fourier Transform Infra-Red (FTIR) test for identification of functional groups and surface chemistry, and differential calorimetric analysis/thermogravimetric (DSC/TGA) test for identification of thermal properties. As a result, it was found that fly ash still contains unburned carbon, which significantly affects its color, and has the potential for application as a hydrogen storage material because its pore diameter structure is larger than 0.7 nm. The silica extracted from fly ash is capable of achieving a purity of up to 87% and exhibits excellent thermal stability, especially at temperatures between 120-300 °C; thus, it has the potential to be a catalyst material in the adsorption-desorption reaction of hydrogen by magnesium, although further research is still needed.

This study aimed to screen and characterize halotolerant bacterial isolates, which could enhance plant growth performance in saline soil. Halotolerant bacteria was isolated from weeds rhizosphere grown in saline soil of coastal agricultural land located at Brondong District, Lamongan Regency, East Java Province, Indonesia. This research was conducted from June to September 2018. Seven bacterial isolates can grow in a Nutrient Agar medium containing 10% of NaCl, suggesting that these bacteria were halotolerant. Furthermore, all bacterial isolates were shown to produce indol acetic acid (IAA) and do not induce a hypersensitive response when infiltrated into tobacco leaves. These results explain that these bacteria had potency as plant growth-promoting rhizobacteria (PGPR) and were not tend to be the plant pathogen. The growth of seedlings when inoculated in cucumber seed grown in saline media were higher than those in control. This result suggests that the halotolerant bacteria can enhance the development of cucumber seedlings in saline stress conditions. Three potential halotolerant bacteria i.e., SN22, SN23, SN26 were selected and molecularly identified as Bacillus megaterium, Bacillus sp., and B. megaterium, respectively. [ABSTRACT FROM AUTHOR]

Thermal energy storage is an important element in order to conserve the energy and optimize the overall efficiency. Development of energy storage system for local purposes requires some information on the raw material which is abundantly available in the local market. This study aimed to investigate the characteristics of traditionally produced salt in Aceh in terms of its potential use as a raw material for thermal energy storage. The sample was collected from the Aceh Besar District and treated by heating at temperatures of 400 °C and 800 °C in a muffle furnace. This treatment is carried out to study the changes in properties and define the best procedure for salt preparation. All samples were characterized under a number of techniques including XRF, XRD, SEM/EDS, TGA/ DSC analysis, density, thermal conductivity, and electrolytic conductivity. The XRF characterization showed that the local Aceh salt was graded as a category III salt. Furthermore, according to the TGA/DSC characterization, the melting temperature is close to 800 °C, and the enthalpy value is close to 492 kJ/kg. It is ample evidence that the Aceh salt can be used as a thermal energy storage material. Furthermore, increasing the temperature of local salt’s heat treatment contributes to increasing the enthalpy value, crystal size, density, thermal conductivity, and electrolyte conductivity.
