Travertine is a non-marine carbonate rock precipitated from calcium- and bicarbonate-rich waters, commonly associated with hot springs, streams, and lakes in tectonically active regions. This study presents a systematic literature review of travertine deposit characteristics, encompassing mineralogical composition, geochemical signatures, petrographic textures, morphological types, isotopic properties, biotic–abiotic controls on formation, early diagenesis, and petrophysical implications. The synthesis indicates that travertine is predominantly composed of calcite, with aragonite forming under conditions of elevated temperature, high Mg/Ca ratios, and rapid CO₂ degassing. Travertines display exceptional textural diversity, ranging from abiotic crystalline crusts to microbially mediated fabrics such as shrub, peloidal, and stromatolitic structures. Major morphologies include fissure ridges, mounds, terraces, cascades, and slopes, strongly governed by tectonic setting, topography, hydrology, and substrate geology. Stable isotopes (δ¹³C and δ¹⁸O), strontium isotopes, trace elements, and REE patterns effectively constrain fluid provenance and distinguish thermogene from meteogene travertines. Microbial activity plays a crucial role in biomineralization, influencing precipitation rates, crystal morphology, and lamination patterns. Early diagenetic processes occurring during active deposition may significantly modify primary fabrics and geochemical signals. Travertine petrophysical properties exhibit distinctive porosity–velocity relationships, making them valuable analogues for subsurface carbonate reservoirs. This review highlights that travertines record complex interactions among physical, chemical, biological, and geological processes and hold significant value for paleoenvironmental reconstruction and carbonate reservoir studies.

. Malnutrition rates among children remain quite high, according to 2024 national statistics, which indicate that good eating habits in accordance with balanced nutritional needs are not yet ideal. Children's eating habits, dietary diversity, and parental understanding all impact their nutritional status. To promote optimal growth and development in children, it is crucial to monitor and establish appropriate eating habits from an early age. The aim of this study was to determine the relationship between eating habits and nutritional status of preschool-aged children. This study used a cross-sectional analytical design and quantitative methodology. Purposeful sampling was used to select a sample of 33 children from the 50 children in the study population. The study was conducted between September 22 and October 1, 2025. A Food Frequency Questionnaire (FFQ) was used to examine dietary patterns, while nutritional status was measured through weighing using a digital scale. Based on the findings, 22 children (66.7%) had a healthy diet, while 11 children (33.3%) had a poor diet. The Chi-Square statistical test showed a p value of 0.008 (p < 0.05), indicating a relationship between eating habits and nutritional status in preschool children at Taman Annisa Miruek Kindergarten, Aceh Besar Regency. According to balanced nutrition guidelines, parents should regularly assess their children's growth and focus more on the diversity and balance of their food intake. To improve children's nutritional status as much as possible, schools are required to collaborate with health workers to educate parents and children about nutrition.

The fisheries sector plays an important role in Indonesia’s economy due to its abundant marine resources; however, unsustainable fishing activities have caused damage to marine ecosystems and a decline in biodiversity. To support sustainable fisheries management, the use of environmentally friendly fishing gear is essential. At the Tenau Coastal Fishing Port (PPP Tenau) in Kupang, East Nusa Tenggara, handline fishing is the most commonly used traditional fishing method among small-scale fishers because it is selective and causes minimal habitat disturbance. This study aims to analyze the environmental friendliness level of handline fishing gear based on the nine criteria of the Code of Conduct for Responsible Fisheries (CCRF) established by FAO in 1995, which include gear selectivity, habitat impact, fisher safety, catch quality, product safety, by- catch, biodiversity impact, capture of protected species, and social acceptance. The research was conducted from November 2025 to January 2026 using a descriptive quantitative method involving 30 handline fishermen selected from a population of 420 using the Slovin formula with a 20% error rate. Data were collected through observation, interviews, and documentation, then analyzed using a weighting system based on the guidelines of the Ministry of Marine Affairs and Fisheries (2006). The results are expected to show that handline fishing is categorized as environmentally friendly to highly environmentally friendly and can serve as a basis for developing sustainable fisheries management policies in East Nusa Tenggara.

This research is motivated by the reality of ethnic and cultural diversity in congregation life which reflects the dynamics of a multicultural society, where differences in cultural identity have the potential to cause social friction if not managed wisely. This research uses a descriptive qualitative approach with normative studies, with data collection techniques through interviews, observations, and documentation of informants consisting of pastors, congregation councils, and presbyters. The theory used is Ralph Linton's role theory which explains how individuals carry out social functions according to their status in society. The results of the study indicate that the life of the GMIT Sion Oepura congregation is characterized by multicultural dynamics as seen from the diversity of ethnicities such as Timor, Rote, Sabu, Flores, and Alor which not only enriches church life through cultural expressions in worship and church activities, but also gives rise to symbolic friction between ethnic groups, such as the tendency for the dominance of certain cultural symbols and the emergence of group ego attitudes in several worship activities, for example in the celebration of Language and Culture Month. In this situation, religious leaders play a role as leaders who embrace diversity, mediators in managing potential conflicts, and social and moral role models for the congregation through sermons, pastoral guidance, and various service activities that involve the entire congregation without differentiating cultural backgrounds. Despite the existence of cultural differences and the tendency for certain symbolic dominance, religious leaders are able to manage this diversity normatively so that it does not develop into open conflict. This study concludes that the role of religious leaders is very important in strengthening social solidarity and maintaining harmony in multicultural congregations.

The integration of Pancasila values within the tourism sector such as mutual cooperation, environmental stewardship, social justice, and respect for cultural diversity can foster sustainable tourism development that balances economic growth with moral responsibility. Furthermore, these values contribute to strengthening national identity, preserving local wisdom, and enhancing community participation in tourism activities. The study also highlights that tourism grounded in Pancasila principles can improve social welfare by empowering local communities and promoting inclusive development. In conclusion, the application of Pancasila principles in tourism development is essential for maintaining a balance between economic progress and socio-cultural preservation, while reinforcing national character and resilience in the face of globalization and rapid global change.

This study aims to analyze the influence of Qirâat (variant Qur’anic readings) on the interpretation of legal verses in Adhwâ’ al-Bayân by Muhammad al-Amîn al-Syinqîthi. Employing a qualitative library research approach, this study examines how both mutawâtir and syâdz Qirâat contribute to the process of Islamic legal deduction (istinbâth). The findings reveal that Qirâat function not merely as linguistic variations but also have significant implications for expanding, reinforcing, and providing flexibility in legal meanings across various domains, including worship (ibadah), family law (munâkahât), transactions (mu‘âmalah), and jihad. Al-Syinqîthi integrates linguistic analysis, textual evidence, and the objectives of Islamic law (maqâṣid al-syarî‘ah) in a comprehensive manner, enabling him to accommodate different Qirâat without generating legal contradictions. Mutawâtir Qirâat serve as the primary foundation for legal rulings, while syâdz Qirâat function as complementary and supportive arguments. This study concludes that the diversity of Qirâat constitutes an integral component of Qur’anic exegesis and Islamic jurisprudence, contributing to the development of a flexible, contextual, and relevant Islamic legal framework.

This article discusses strengthening civic identity through multicultural education based on local wisdom in Gorontalo Regency. The main problem raised is how local culture, although recognized as a symbol of regional identity, has not been fully translated into an inclusive and reflective pedagogical design to shape students' civic awareness. This study uses a qualitative case study design based on document analysis, with data sources in the form of indexed journal articles, regional official publications, and educational documents published in 2021–2026. The focus of the study is directed at educational practices in Limboto and Dungaliyo. The data was selected purposively based on relevance, credibility, and thematic proximity, then analyzed through the stages of data reduction, data presentation, and conclusion drawn. The results of the study show three main findings: first, huyula local wisdom as the value of mutual cooperation, solidarity, and collective responsibility functions as a cultural bridge that connects social diversity with civic disposition. Second, multicultural education is more effective when local values are explicitly integrated into classroom interactions, school habituation, collaborative work, and reflective discussions. Third, challenges arise because many local values are still implicitly practiced so that they have not yet formed a reflective citizenship consciousness. This article concludes the need for a shift from symbolic recognition to structured pedagogical design through curriculum contextualization, teacher mediation, and school-to-community partnerships.

Illegal logging is a serious environmental problem in Indonesia due to its direct impact on forest destruction, biodiversity loss, and increased carbon emissions. The Indonesian government has established various public policies and legal instruments to address illegal logging practices, such as the Forestry Law, the licensing system, and strengthening law enforcement agencies. However, the effectiveness of these policies remains a concern, given that illegal logging cases continue to occur in various regions. This study aims to assess the effectiveness of public policies in enforcing environmental law, focusing on illegal logging cases in Indonesia. The method used in this study is a normative juridical approach by examining regulations, government policies, and secondary data from reports from relevant institutions and previous research results. Analysis shows that despite comprehensive public policy design, its implementation still faces various obstacles, such as weak oversight, poor coordination between institutions, limited human resources, and corrupt practices. Furthermore, social and economic factors in communities surrounding forests also influence the success of environmental law enforcement. Therefore, strengthening law enforcement agencies, transparency and accountability, and active community involvement in forest management are essential. With these improvements, public policy is expected to be more effective in preventing and combating illegal logging for the sake of environmental sustainability in Indonesia.

This article examines three major streams of Islamic political thought in Indonesia through a comparative analysis of the ideas of Mohammad Natsir, Abu Bakar Ba’asyir, and Abdurrahman Wahid (Gus Dur). Mohammad Natsir embodies the constitutional–integralist perspective, which seeks to formalize Islam as the foundation of the state by utilizing democratic mechanisms and constitutional political processes. In contrast, Abu Bakar Ba’asyir reflects a radical–ideological orientation that firmly rejects democracy and advocates the full implementation of Islamic Sharia through extra-constitutional and non-parliamentary movements. Meanwhile, Abdurrahman Wahid represents a substantive–cultural approach, opposing the formal institutionalization of Islam within the state while promoting Islamic values as ethical guidance for building a tolerant and pluralistic nation. The contrasting viewpoints of these three figures highlight the diversity of Islamic political discourse in Indonesia and illustrate the evolving interaction between religion and state. Overall, this study demonstrates how Islamic thought continues to adapt and remain relevant within Indonesia’s multicultural and democratic context.

This research examines how families and communities play a role in instilling the value of tolerance through multicultural education. As a country rich in ethnic, religious, cultural and linguistic diversity, Indonesia needs an attitude of mutual respect so that social life continues to run in peace and harmony. Therefore, it is important to introduce the value of tolerance from an early age through the child's closest environment, such as family, community and school. In everyday life, the family is the first place where children receive education about tolerance through providing understanding, habituating positive behavior, example from parents, and monitoring children's attitudes. On the other hand, society also has a contribution as a learning environment that introduces children to diversity through social interaction and various joint activities. Schools also play a role in forming a tolerant character by implementing multicultural education in a planned and sustainable manner. This research uses a literature study method by examining various scientific sources related to multicultural education and instilling the value of tolerance. Based on the results of the study, it is known that cooperation between family, school and community has a very important role in shaping children's character so that they are able to appreciate differences, live side by side in harmony, and maintain unity in the life of a diverse society.

Dengue remains a major vector-borne disease worldwide, and the increasing resistance of Aedes aegypti to synthetic insecticides has encouraged the exploration of environmentally friendly botanical larvicides. This study aimed to systematically evaluate scientific evidence regarding the larvicidal potential of endemic Kalimantan plants against Aedes aegypti and to identify priority candidates for future research. A systematic literature review was conducted following the PRISMA 2020 guidelines. Literature searches were performed across Scopus, PubMed, ScienceDirect, SpringerLink, Web of Science, MDPI, Wiley Online Library, Garuda, SINTA, and Google Scholar for studies published between January 2016 and January 2026. A total of 925 records were identified, and after duplicate removal, screening, and eligibility assessment, 88 studies were included in the final synthesis. The results showed that botanical larvicides rich in alkaloids, flavonoids, terpenoids, phenolics, limonoids, and sulfur compounds demonstrated significant larvicidal activity against Aedes aegypti. However, no direct larvicidal studies were identified for endemic Kalimantan species, including Fibraurea tinctoria, Arcangelisia flava, Dacrydium beccarii, Agathis borneensis, and Scorodocarpus borneensis. These findings highlight substantial evidence gaps and indicate that Kalimantan biodiversity represents a promising source of novel larvicidal agents for sustainable dengue vector control.

Environmental damage caused by human activities has become an increasingly pressing global issue. Poetry as a literary work has the power to represent ecological problems symbolically and critically. This study aims to describe the representation of the impact of the environmental crisis in Taufiq Ismail's poems, namely "Menengajah Ke Atas, Merenungi Ozone yang Tak terlihat" and "Membaca Tanda-Tanda." The analysis is based on Greg Garrard's ecocritical study. This study uses a qualitative method with content analysis techniques. There are two stages of analysis, namely the literal and symbolic meaning of the poems, then an ecocritical interpretation is carried out based on Garrard's categories which include pollution, wilderness, apocalypse, dwelling, animals, and earth. The results of the study indicate that both poems represent the impact of the environmental crisis through health problems due to pollution and radiation, damage to water and forest ecosystems, climate change, threats to human living space, and the decline in biodiversity. The research findings also show that the most dominant categories are pollution and apocalypse, which confirms that the environmental crisis in Taufiq Ismail's poems is the result of human behavior that ignores nature. Thus, Taufiq Ismail's poems not only function as aesthetic works, but also as cultural criticism and moral warnings for humanity.

Indonesia is a country rich in cultural diversity, one of which is Javanese culture which is full of philosophical values ​​and symbolic meanings in every practice, including in the traditional wedding procession. One of the important rituals in Javanese traditional weddings is the Panggih Manten ritual, which represents the meeting between the bride and groom with various symbols of life, hope and blessings. Along with the development of the times and the flow of modernization, people's understanding of the philosophical meaning of the ritual has shifted. Some people still carry out this tradition as a hereditary custom without understanding the values ​​contained in it, even giving rise to debates regarding its suitability with Islamic teachings. This study aims to analyze the practice of the Panggih Manten ritual in Javanese traditional wedding traditions and review its suitability with the 'Urf argument in Islamic law. The research method used is qualitative with a juridical-normative approach, while the research location was carried out in Pengkol village, Mantingan District. The results of the study show that the Panggih Manten ritual is basically acceptable in Islamic law as long as it does not conflict with the principles of sharia. Based on analysis from the perspective of al-'urf, several aspects of the Panggih Manten ritual, such as muter asem (the act of making offerings), and the belief in disasters, contain elements that are inconsistent with Islamic law and could potentially lead to idolatry, thus being categorized as al-'urf al-fāsid. Therefore, the Panggih Manten tradition can be preserved through reinterpretation of its meaning and the elimination of elements that contradict Islamic teachings, thus aligning it with Islamic principles.

Indonesia is a country rich in cultural diversity, one of which is the Tedak Siten tradition that is still preserved by Javanese communities, including those in Bancar Village. This tradition is not merely a cultural heritage but also contains important educational and spiritual values in community life. This study aims to understand the meaning of the Tedak Siten tradition, identify the educational and spiritual values embedded within it, and analyze it from the perspective of Islam Nusantara. The research employs a qualitative descriptive approach using observation, interviews, and documentation techniques, with informants selected purposively from community members directly involved in the tradition. The findings reveal that Tedak Siten functions as a medium for character education, instilling values such as independence, responsibility, and perseverance from an early age. In addition, the tradition strengthens spiritual values through prayers and expressions of gratitude to Allah SWT. From the perspective of Islam Nusantara, Tedak Siten reflects a harmonious acculturation between local culture and Islamic teachings without contradicting the principle of monotheism. The implications of this study indicate that local traditions can be utilized as contextual learning resources in Islamic education while also serving as a means of preserving valuable cultural heritage. Therefore, Tedak Siten remains relevant not only as a tradition but also as a medium for character building and strengthening religious values in society.

The accentuation of these inclusive values is expected to become the foundation for a more just and sustainable coastal community in Makassar.

The Panji Story is one of the Intangible Cultural Heritage (ICH) that has historical, cultural, and local identity values, especially for the people of Kediri. However, currently, the community's understanding of the Panji Story tends to be limited and is often considered only as a romantic story, so that the historical and cultural values contained therein are not fully understood. This activity aims to strengthen the community's understanding of the Panji Story as a source of history and local cultural heritage through a national seminar. The activity was conducted in the form of a seminar involving presentations by expert speakers, interactive discussions, and question and answer sessions with participants from various backgrounds, such as students, the general public, and cultural activists. The results of the activity showed an increase in participants' understanding and awareness of the historical, cultural, and educational value of the Panji Story. Participants not only understood the diversity of versions of the Panji Story, but also began to view it as an important part of local cultural identity that needs to be preserved and sustained. This activity showed that national seminars can be an effective educational medium in building collective public awareness of the sustainable preservation of local history and culture.

The agricultural sector plays a strategic role in meeting food needs while maintaining environmental sustainability and community welfare. However, conventional farming practices that rely on chemical inputs have caused various problems, such as soil degradation, loss of biodiversity, and environmental pollution. This condition has encouraged the adoption of the Sustainable Agriculture concept, which emphasizes a balance between ecological, economic, and social aspects. Its successful implementation is strongly influenced by farmers’ perceptions as the main actors. This study aims to analyze rice farmers’ perceptions of the implementation of Sustainable Agriculture in swampy areas of Tebas District, Sambas Regency. The research was conducted from October to November 2025 using a survey method involving 95 farmers selected through the Slovin formula and proportional random sampling technique. Data were collected through observation, interviews, and Likert-scale questionnaires, and analyzed using descriptive analysis and binary logistic regression. The results show that farmers’ perceptions are generally positive, particularly regarding water management, variety selection, and cropping patterns. However, the use of organic fertilizers, environmentally friendly pest control, and post-harvest management are still considered difficult. Education level and non-farming occupations significantly influence farmers’ perceptions. Therefore, enhancing extension services, training, and support for business diversification is necessary to promote the adoption of Sustainable Agriculture.

The customary forest of Sub-Tribe Afsya, Bariat Village, South Sorong Regency, Southwest Papua is a lowland tropical rainforest of approximately 2,500 hectares managed under the indigenous "Sasi Adat" system. This study aimed to determine bird species diversity, evenness of distribution, and the relationship between bird communities and vegetation structure. Research was conducted in January 2026 using a combination of line transect and point count methods along five 1,000-meter transects, observed in the morning (06:00–10:00 WIT) and afternoon (15:30–18:00 WIT). Data were analyzed using the Shannon–Wiener Diversity Index (H’), Simpson's Dominance Index (D), Evenness Index (E), and vegetation Important Value Index (IVI). The study recorded 30 bird species from 16 families with 492 individuals, including 12 Papua-endemic species protected under Minister of Environment and Forestry Regulation No. P.106/2018. H’ values ranged from 1.197 to 2.472 (moderate to high); dominance was low to moderate; and evenness ranged from 0.668 to 0.933, with most transects showing high evenness (E > 0.75). Vegetation was dominated by damar trees (Agathis labillardierei) and fruiting trees synergistically supporting frugivore, insectivore, and nectarivore bird guilds. The Sasi Adat management system demonstrably contributes to habitat quality, rendering this forest of significant conservation value for Southwest Papua's avifauna.
