This study examines whether economic policy ideologies or economic threat perceptions predict Indonesian Muslim voters’ support for non-Muslim political leaders. Using 2018 World Values Survey data from 1877 employed Muslim respondents, the analysis tests two competing mechanisms. Traditional economic ideologies —preferences for income distribution, government ownership, welfare policies, and success determinants—show no relationship with support for non-Muslim leaders across presidential, mayoral, and parliamentary positions, confirming that left–right economic cleavages do not structure Indonesian political competition. However, perceptions of competition as threatening significantly reduce support for non-Muslim candidates, with effects strongest at local legislative levels characterized by direct patron–client relationships. Inter-religious trust buffers against competition-based exclusion, while competition anxiety manifests through eroded neighborhood trust and labor market concerns rather than explicit outgroup rejection. Moderate institutional trust correlates with viewing competition as harmful, suggesting partial confidence heightens awareness of competitive risks. These findings demonstrate that economic factors relate to religious-political attitudes through psychological mechanisms of perceived threat rather than ideological alignment, extending post-Ahok scholarship on religious mobilization by specifying individual-level pathways linking economic anxieties to political exclusion.

<title>Abstract</title> Tropical coastal cities such as Bandar Lampung, Indonesia, are experiencing rapid urbanization, leading to increased surface temperatures (Land Surface Temperature/LST) and energy consumption as reflected in nighttime light (NTL) emissions. These phenomena degrade environmental quality and reduce urban livability. This study aims to identify land potential for expanding green open spaces (GOS) by analyzing the spatial correlation between LST intensity and NTL emissions using the Geographically Weighted Regression (GWR) method. Surface temperature data were derived from Landsat 8 imagery, while NTL data were sourced from the VIIRS satellite. The findings reveal a significant spatial relationship between high light emissions and elevated surface temperatures. Moreover, several zones with high LST intensity but low light emissions were identified as potential areas for GOS intervention. These results provide a scientific basis for formulating climate-adaptive urban planning strategies and enhancing environmental quality in rapidly growing coastal cities.

<title>Abstract</title> Functional metagenomics has emerged as an effective tool for discovering novel enzymes directly from environmental samples, overcoming the limitations of traditional culture-based methods. In this study, we used a functional metagenomic approach on a stool sample from <italic>Axis kuhlii</italic> , an endemic deer species from Indonesia, to identify active cellulases. We created an efficient workflow for enzyme expression directly in <italic>Komagatella phaffii</italic> by combining metagenomic sequencing to investigate enzyme diversity, multiplex PCR to build a genes library, and rolling circle amplification (RCA) to streamline the cloning process, eliminating the need for intermediate <italic>Escherichia coli</italic> transformation and propagation steps. Furthermore, a semi-high-throughput screening method was used to evaluate multiple samples at once, allowing for the rapid identification of active enzymes. Using this approach, we discovered five novel endoglucanases and three β-glucosidases with confirmed enzyme activity. This study shows that functional metagenomics can bridge the gap between computational predictions and experimental validation, providing a reliable platform for enzyme discovery and characterization from complex environmental microbiomes.

The Five-Factor Model (FFM) is the most widely used framework for understanding personality, typically assessed through self-report inventories such as the IPIP-NEO-120. Although these tools show strong psychometric properties, reliance on self-reports introduces vulnerabilities to bias, including social desirability, response distortion, and faking, particularly in high-stakes contexts like personnel selection. To address such limitations, researchers have increasingly explored behavior-oriented measures, notably Situational Judgment Tests (SJTs). When analyzed using Cognitive Diagnostic Models (CDMs), SJTs can yield multidimensional mastery profiles that offer a nuanced representation of personality. However, limited evidence exists regarding the convergence between CDM-based SJT profiles and traditional self-reports. This study applied Robust Canonical Correlation Analysis (RCCA) with a Spearman rank correlation matrix to examine structural alignment between CDM-based SJT scores and IPIP-NEO-120 domain scores in a sample of 289 participants. RCCA was chosen to handle common violations of multivariate assumptions, such as non-normality and outliers. Results showed a moderate canonical correlation in the first root, supporting convergent validity while highlighting distinct trait representations across methods. Subsequent roots yielded weaker and less stable associations. Overall, findings indicate that RCCA is a viable approach for evaluating cross-method validity and emphasize the complementary insights of situational and self-report approaches in personality assessment.

Indonesia routinely imports buffalo to meet domestic meat demand, however outbreaks of theileriosis caused by Theileria orientalis have been reported in Vietnam among imported buffalo. Early detection is crucial in Jambi Province, which receives large consignments of buffalo meat. Theileriosis is an intracellular protozoan infection caused by Theileria sp., significantly affects livestock health and productivity. Information on detection and genetic diversity of Theileria sp. in Indonesian buffalo remains scarce. This study aimed to identify Theileria sp. from imported buffalo arriving in Jambi and to analyze their phylogenetic relationship with isolates from other regions using microscopic examination, PCR, and 18S rRNA sequencing. A total of 38 blood samples were examined microscopically and tested by PCR targeting the 18S rRNA gene, followed by Sanger sequencing for phylogenetic analysis. Microscopic examination did not reveal intraerythrocytic piroplasms, whereas PCR confirmed infection in two samples, yielding an prevalence of 5.26%. Phylogenetic reconstruction using the maximum likelihood method demonstrated that Jambi isolates shared high nucleotide homology and clustered with T. orientalis from Thailand and T. buffeli from Myanmar, Vietnam, and India, supported by a bootstrap value of 85%. These findings suggest the possibility of transboundary dissemination of T. orientalis genotypes through livestock trade. This study contributes to understanding the distribution and genetic relationship of T. orientalis in buffalo imported into Indonesia and provides useful insights for epidemiological studies.

This study aims to explore the application of the principle of social justice in the development of the new capital city IKN towards the collective rights of indigenous peoples, as well as the legal challenges they face in defending their rights during the development process. The research amploys by the qualitative approach, with the data collected from litelature studies. The data include books, articles journal scientific, news, studies academic, official website governmen, and others reference relevant. In the process of writing and discussing in this academic is used descriptive analytical method. The findings of this research is development of the National Capital City (IKN) in North Penajam Paser can bother rights collective public customs in the environment. These impact include the loss of customary land, neglect of culture local, and social injustice consequence from the lack of involvement public custom in the planning and development process. Research results This can used as base for maker policy For to design regulation inclusive and equitable development social. The result of this study is about the push involvement active public custom in the planning process development, as well as strengthening protection law to right customs and culture threatened local. The novelty from this study lies in focus integrated analytical focus in the social justiceperspective to phenomenon of the dispossession of the public collective right in the Balik indigeneous community. This research fills in emptiness studies in previous that have not thoroughly examined the social justice in dimension of the context of IKN development and the impact on the existence of local indigeneous communities.

This study aims to examine the spiritual relationship between humans and nature in Mappangiso healing practices in Soppeng Regency. The subjects of the study were Bugis sanro who were involved in healing rituals. With a qualitative approach and Starhawk's spiritual ecology theory, it was found that Mappangiso integrates natural elements and mantras as healing media. This tradition reflects ecospiritual awareness and local wisdom in maintaining ecological balance and health.
