The Perintis Lake area in Bone Bolango Regency, Gorontalo Province, faces a growing conflict between tourism investment and environmental conservation. This study aims to analyze the impact of tourism infrastructure development on the lake’s ecosystem, highlight the importance of conservation, and provide strategic recommendations for sustainable tourism development. Using a qualitative-descriptive approach, the research is based on field observations, literature review, and regional policy analysis. Findings show that unregulated investment activities, particularly constructions along the lake's buffer zone, have led to environmental degradation, such as water pollution, habitat loss, and ecological imbalance. Conservation efforts remain fragmented and lack integration into broader development planning. The study recommends the implementation of sustainable spatial planning policies, stricter environmental regulations, and active community involvement. Collaborative governance between local authorities, private investors, and environmental stakeholders is essential to ensure that economic development aligns with ecological preservation. Striking a balance between investment and conservation is key to maintaining Perintis Lake as a resilient ecotourism destination for future generations.

Land degradation due to intensive agricultural practices is a serious issue threatening food security and ecosystem balance. Monoculture farming systems often lead to soil fertility decline, increased erosion, and reduced soil biodiversity. As an alternative, agroforestry has been developed to enhance agricultural productivity without compromising soil health. Agroforestry integrates agricultural crops with trees or other woody plants in a mutually beneficial system. Several studies have shown that agroforestry improves soil organic matter content, retains soil moisture, and reduces erosion and nutrient loss. This study employs a literature review method to analyze the effectiveness of agroforestry in improving soil health and agricultural productivity. Agroforestry has been found to enhance agricultural productivity through crop diversification, efficient land use, and climate change mitigation. Diversification not only strengthens food security but also increases farmers’ income by minimizing crop failure risks and enhancing nutritional value. Additionally, agroforestry optimizes land use by improving yield per unit area and reducing environmental degradation through natural resource conservation. Agroforestry also plays a crucial role in mitigating climate change by increasing ecosystem resilience, sequestering carbon, and reducing extreme weather impacts. However, the adoption of agroforestry faces challenges, including a lack of farmers’ knowledge, limited policy support, and varying environmental conditions. Addressing these barriers through improved education, supportive policies, and sustainable resource management can accelerate agroforestry adoption. With broader implementation and strong policy support, agroforestry can drive agricultural sustainability and enhance community well-being.

The increase in human activities, such as industrialization, urbanization, and transportation, has led to air pollution, including heavy metal contamination such as lead (Pb). Lead originates from vehicle emissions, industrial activities, and fossil fuel combustion, which have detrimental effects on the environment and human health. One effective method for monitoring air pollution is biomonitoring using bioindicators, such as lichen. Lichen is sensitive to air quality and can absorb pollutants, including heavy metals, through its surface. This study uses a literature review to analyze the role of lichen as a bioindicator of heavy metal pollution, specifically lead. Several lichen species, such as *Xanthoparmelia xanthofarinosa* and *Canoparmelia aptata*, are known to accumulate heavy metals from the environment. The results show that the lead content in lichen varies depending on the pollution level in the location. Areas with high traffic have higher lead concentrations compared to areas with low traffic. The advantages of using lichen as a bioindicator include low cost, practicality, and its ability to provide long-term data on air quality. With this understanding, lichen data can be used for pollution mitigation and evidence-based policies to reduce the impact of air pollution. Further research is recommended to explore the potential of lichen in detecting other heavy metals, such as cadmium (Cd) and copper (Cu).
 

This study aims to analyze the level of attack by Macaca hecki on cultivated plants in Makarti Jaya Village, Pohuwato, Gorontalo. Agriculture is the main source of income for the local community, but the presence of Macaca hecki can threaten agricultural yields. The method used in this research is descriptive qualitative, with data collected through direct observation and interviews with farmers experiencing the attacks. The results indicate that corn (Zea mays) is the most consumed plant by Macaca hecki, followed by cocoa (Theobroma cacao) and several other types of fruit such as bananas and papayas. The high consumption rates of these cultivated plants negatively impact agricultural results, causing significant economic losses for farmers. Therefore, it is important to understand the attack patterns and the factors influencing the behavior of Macaca hecki. This research recommends the need for more effective protection strategies, such as the placement of physical barriers and diversification of plant types. Thus, it is hoped that this study can contribute to the management of conflicts between wildlife and agriculture, as well as enhance the economic sustainability of farming communities.

This research aims to evaluate strategies for increasing beef cattle productivity through optimizing concentrate feed based on local ingredients in Perbaungan, Serdang Bedagai Regency. Surveys and interviews were conducted to collect data regarding feeding patterns, costs and production efficiency. The research results show that concentrate feed, although more expensive than forage, provides higher efficiency in supporting daily weight gain in beef cattle. Local ingredients such as rice bran, palm oil cake and tofu dregs have great potential for use in concentrate formulations, thereby reducing costs and increasing the sustainability of livestock businesses. Optimal strategies include providing concentrate as needed, combining with forage, and managing feed stock. This optimization has been proven to be able to increase beef cattle. productivity and support national meat self-sufficiency efforts

Indonesia is one of the countries with the highest levels of biodiversity in the world and possesses vast tropical forest areas that play a crucial role in maintaining the stability of global ecosystems. However, in recent decades, Indonesia’s forests have faced significant pressures due to deforestation and environmental degradation, which have broad impacts on ecological functions, climate balance, and the socio-economic lives of communities. This study aims to examine the role of biodiversity and ecological adaptation mechanisms in maintaining the stability of Indonesia’s forest ecosystems through a literature review approach. The findings show that deforestation directly affects biodiversity decline, habitat fragmentation, disruption of hydrological systems, increased erosion, and carbon emissions. Additionally, illegal activities such as logging and mining exacerbate environmental degradation. Biodiversity is proven to be an important factor in enhancing ecosystem resilience to disturbances, including climate change. Adaptation mechanisms such as the presence of bioindicator species, the formation of ecological corridors, and community participation in conservation can strengthen ecological resilience. Rehabilitation of degraded areas and the implementation of sustainable governance policies are necessary to restore the ecological functions of forests. This study emphasizes the importance of a multidisciplinary and collaborative approach in conservation strategies, supported by strong scientific, social, and institutional frameworks to ensure the sustainability of Indonesia’s forest ecosystems in the future.

The rapid growth of the city in Pulubala Urban Village, Gorontalo City, has resulted in pressure on the environment and the use of green open space (RTH).
