Abstract

As human activities degrade the environment, comprehensive environmental knowledge is vital for sustainability. This paper reviews literature across disciplines to synthesize ecological principles, ethics, environmental threats, and solutions. Major challenges analyzed include climate change, biodiversity declines, pollution, and overexploitation. Conservation approaches like protected areas are examined, along with environmental law and sustainable development integrating economic, social, and ecological dimensions. Implementing sustainability requires transforming awareness, values, and behaviors toward environmental responsibility across society. Findings integrate insights from ecological and social sciences. This interdisciplinary framework informs urgent ethical policies and lifestyle changes to mitigate threats and uphold ecosystem integrity. Despite complex systemic challenges, creative collaboration can integrate human civilization and nature conservation for thriving societies.

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

Groundwater quality degradation in small volcanic islands presents complex challenges for freshwater availability, particularly where communities heavily rely on groundwater resources. A study of groundwater dynamics in dug wells on Ternate Island, Indonesia, examined the relationship between water volume changes and water quality parameters while evaluating seawater intrusion potential through hydrostatic balance analysis. Researchers measured physical parameters (temperature, surface pressure) and chemical parameters (salinity, dissolved oxygen, electrical conductivity, total dissolved solids) in three sample wells and one coastal point. The analysis incorporated calculations of water volume changes, flushing rates, and regression analysis between water volume changes and water quality parameters to assess the dynamics of groundwater quality fluctuations. Water level changes showed a 27-minute lag after tidal shifts, with well 1 showing dominant volume changes during ebb tide (65%), while wells 2 and 3 were dominant during flood tide. Well 2 showed higher susceptibility to quality changes due to its lower flushing rate (13.7%) compared to well 1 (56.6%). Statistical analysis revealed that water volume increases did not significantly influence water quality changes (p > 0.05). These findings enhance our understanding of groundwater dynamics in volcanic islands and suggest that factors beyond water volume changes should be considered when managing groundwater resources in these settings. The research provides valuable insights for developing effective water resource management strategies in similar geological contexts worldwide.

Abstract

The infestation of Anisakis spp. in Chub mackerel (Scomber japonicus) may have significant health and socioeconomic implications. Understanding the spatio-seasonal occurrence of Anisakis spp. in its host, S. japonicus, is crucial ecologically and for effective management. This research aimed to develop a predictive map (spatial-seasonal patterns) for Anisakis’s infestation in S. japonicus using the maximum entropy (MaxEnt) algorithm. Anisakis spp. and S. japonicus occurrences were obtained through a comprehensive Bibliographic analysis of the Scopus database (2017-2022) and the Ocean Biodiversity Information System (OBIS) database to collect the necessary data. Environmental predictors were sourced from the Global Marine Environment Data. The resulting model demonstrated a reliable performance, as indicated by an Area Under Curve (AUC) value on the Receiver Operating Characteristic (ROC) chart exceeding 0.8. The findings of this study revealed that the infestation of Anisakis spp. in S. japonicus is projected to be more prevalent during the fourth quarter of each year. Furthermore, the environmental factors influencing the infestation were identified as diffuse attenuation, water depth, and distance from the coast. These research outcomes can be a foundational reference for developing an effective control system for inspecting fresh or frozen fish within the quarantine department. By utilizing the spatial-seasonal patterns and environmental predictors identified in this study, authorities can implement targeted measures to prevent and mitigate the infestation of Anisakis spp. in S. japonicus, safeguarding public health and maintaining the quality of fish products.
