Abstract

Indonesia, known for its high biodiversity, is threatened due to alien plants that invade local plant species in forest areas. West Bali National Park is overgrown with invasive exotic plants, such as Lantana camara L., known locally as the kembang telek. The research aims to predict the distribution of L. camara using species distribution models (SDMs) and analysis variable contribution in the model featured in the biodiversity climate change virtual laboratory (BCCVL) application. L. camara distribution prediction model in Bali used the Bioclim data input by identifying areas of low, medium, and high habitat suitability. Central mountainous regions, including parts of Buleleng, Jembrana, Bangli, Karangasem, and Tabanan, show the highest suitability. Response curves demonstrated the correlation between climate variables and occurrence probability, highlighting the specific condition of rainfall and temperature ranges favoring Lantana's growth. The model showed a reliable AUC value of 0.89, indicating realibility. Potential improvements through additional environmental parameters were suggested. While L. camara has some potential benefits as a medicinal plant in Balinese culture, its invasive nature poses significant threats to native ecosystems. The predictive map offers valuable insights for authorities to implement initiative-taking strategies for preventing and controlling Lantanas spread in vulnerable areas of Bali.

Abstract

Locusta migratoria (Linnaeus, 1758) is one of the locusts known as important pests of food crops. Outbreaks of this species can cause catastrophic damage to maize, paddy, and many other crops. A species distribution model was used to identify the probability of the locust's current and future potential distribution in the Indonesian archipelago. The study relied on the machine learning method Maximum Entropy (Maxent) Model to forecast the future spread of the species in the Indonesian archipelago and to find the climate variable that influenced the distribution of Locusta migratoria. The results showed an Area Under Curve (AUC) value of 0.956 for the Locusta migratoria model, indicating a highly reliable model. The important variable for the distribution of this species was precipitation, especially during the dry season. A low amount of rainfall increases the possibility of the species existing and being distributed. Maxent prediction models showed the potential distribution in the southern part of the Indonesian archipelago under both middle and worst-case scenarios for 2070. This model can become one of the baselines for early warning systems, targeted monitoring and surveillance, and the use of specific pesticides or biological control agents to prevent or minimize the harm of Locusta migratoria outbreak to agricultural lands in the future.

Abstract

The Alas Mentaok was a forest dominated by the mentaok tree (Wrightia javanica) that once existed in Yogyakarta, Java Island, Indonesia. This forest has cultural and historical value, as it is believed to be the first location to establish the Mataram Islam Kingdom in Java in 1582 AD. This study utilized species distribution models (SDMs) to investigate the species distribution pattern and assess its latest conservation status in Java and the Lesser Sunda Islands, Indonesia. The methodology used involved collecting occurrence and environmental data of W. javanica, conducting species distribution modeling using the maximum entropy algorithm, evaluating the model's accuracy, and performing an independent assessment of the area of occupancy (AOO) and extensive occurrence (EOO) using the geospatial conservation assessment tool (GeoCAT). While the number of suitable habitat areas for W. javanica in Yogyakarta is projected to decrease by 2100, the islands of Sumba and Timor are anticipated to experience an increase in the suitable habitat areas for the species during the same year. The analysis of BIOCLIM 34 indicates the mean moisture index of the warmest quarter plays a vital role in the current and future projections. AOO calculation in GeoCAT places this species in the endangered (EN) category, particularly within our regions of interest in Java and the Lesser Sunda Islands. Overall, a full assessment combining a habitat suitability model with current conservation status information would provide a more comprehensive understanding of mentaok's habitat preferences and current conservation status in Indonesia.

Abstract

The forested regions within the Bedugul highland stand as some of the last remaining tropical mountain rainforests in Bali. However, recent development in Bedugul indicates a surge in mass tourism, posing a threat to its diverse plant life due to increased land-use changes and overpopulation. Hence, this research aimed to ascertain the composition and diversity of tree communities within the Bedugul highland forest, focusing on Mt. Pohen and Mt. Tapak. While Mt. Pohen has a history of disturbances like the establishment of a geothermal power plant and forest fires, Mt. Tapak experiences comparatively less disruption. The methods include species identification, the diversity index calculation, the species composition and abundance, and the similarity analysis between permanent sample plot (PSP) from Mt. Pohen and PSP from Mt. Tapak. The result shows a clear separation in tree species composition and abundance between both PSPs. Some species are only detected at Tapak but absent at Pohen or vice versa. However, Euphorbiaceae is the dominating family in both mounts, as the species are known as pioneer plants that benefit in growth and adaptation to the highland habitat after disturbance. The most abundant species in a one-hectare plot on Mt. Pohen are Crypteronia paniculata and Acronychia trifoliata. While on Mt. Tapak, it appears to be Dendrochnide stimulans. Both mounts are occupied mainly by tree groups with diameters ranging from 10 to 20 cm.

Abstract

Children's rights advocacy is a series of systematic efforts made by individuals, groups, institutions, or organizations to protect, promote, and ensure the fulfillment of children's rights in accordance with international and national legal standards and norms. This advocacy aims to fight for the best interests of children so that their rights such as the right to protection, education, health, and participation are respected and guaranteed by the state, family, and society, especially in Indonesia which is greatly influenced by religious norms, morals and decency in addition to legal norms. However, children's rights can be threatened due to divorce events that occur between their parents. The divorce triggers those related to the interests of the child whether they are fulfilled or not fulfilled. The divorce process not only has an impact on married couples, but also has significant implications for the children who are part of the family. Children who are in divorce situations are prone to experiencing various negative impacts, both psychological, social, and economic. This study examines the role of advocacy for children's rights after divorce and what are the factors that make the role of advocacy effective. The research uses normative research methods. Normative legal research itself is legal research that is carried out by researching literature materials or secondary data. To then conduct an analysis and study of the ministry a conclusion is taken.

Abstract

A strong command of vocabulary is pivotal in early language development, especially for young learners navigating cognitive and language skill growth. This research examines how fifth graders at SD Islam Sultan Agung 4 expanded their formal language lexicon using the Words of Wonders (WoW) digital tool. A case study methodology was adopted, with data gathered through classroom observations and semi-structured interviews. Analysis indicated that the WoW app significantly boosted learners’ motivation, prompting active participation and greater self-assurance in experimenting with newly acquired terms. Despite this progress, students struggled to consistently use these words in informal contexts. The application’s gamified design created a dynamic and engaging educational setting, amplified by teacher guidance and parental involvement. Recurring issues, such as vocabulary retention gaps and sporadic learner drive, highlight areas needing strategic support. Ultimately, this study underscores WoW’s efficacy as a vocabulary-enhancement platform while advocating for curriculum innovations that leverage interactive technologies to address evolving pedagogical demands.

Abstract

Peran agama dalam membentuk dan memelihara perdamaian global telah menjadi topik diskusi yang signifikan dalam berbagai kajian lintas disiplin, mulai dari teologi, sosiologi, hingga hubungan internasional. Meski kerap kali dikaitkan dengan konflik dan kekerasan dalam sejarah kemanusiaan, agama sejatinya mengandung nilai-nilai universal yang mendorong solidaritas, keadilan sosial, rekonsiliasi, dan non-kekerasan. Artikel ini bertujuan untuk mengeksplorasi secara kritis peran agama sebagai instrumen perdamaian dalam konteks kontemporer yang sarat konflik identitas, polarisasi sosial, dan kekerasan struktural. Dengan menelaah teks-teks suci, ajaran etis dari berbagai tradisi agama besar, serta studi-studi empiris tentang inisiatif perdamaian berbasis agama, tulisan ini menegaskan bahwa agama bukan semata-mata produk budaya, melainkan kekuatan moral dan spiritual yang dapat memperkuat kohesi sosial dan membangun ruang dialog lintas perbedaan. Melalui pendekatan multidisipliner, penulis mengajukan kerangka konseptual yang menempatkan agama sebagai aktor normatif dalam resolusi konflik dan pembangunan perdamaian yang inklusif dan berkelanjutan. Penelitian ini menyimpulkan bahwa perdamaian yang ditopang oleh nilai-nilai keagamaan lebih berpotensi berakar dalam kehidupan masyarakat karena ia menyentuh dimensi terdalam dari identitas dan motivasi moral individu. Oleh karena itu, peran agama dalam proses perdamaian tidak dapat diabaikan, namun harus dimobilisasi secara konstruktif melalui pendidikan, dialog antariman, dan kolaborasi lintas sektoral.

Abstract

This study examines the concept, urgency, and strategies of dakwah (Islamic preaching) in promoting peace, particularly within Indonesia’s plural and dynamic society. In Islam, dakwah is not merely understood as the transmission of religious teachings, but also as a means of social transformation aimed at fostering harmony, preventing conflict, and strengthening the values of tolerance. This research employs a library-based approach, reviewing the Qur’an, Hadith, classical literature, works of contemporary scholars, and relevant academic journals. The findings identify five key strategies for peaceful dakwah: (1) a humanistic approach emphasizing empathy, constructive dialogue, and two-way communication; (2) consistent uswah hasanah (exemplary conduct) in daily life; (3) creative and ethical utilization of digital media to engage younger generations; (4) strengthening multicultural and interfaith dakwah as a means to foster social cohesion; and (5) community empowerment through socio-economic programs grounded in Islamic values. The implementation of these strategies requires strong communication skills, deep contextual understanding, and high moral integrity on the part of the da’i. This study affirms that strengthening peaceful dakwah based on the rahmatan lil ‘alamin principle is a strategic step toward building an inclusive, just, and civilized society in the era of globalization.
