<![CDATA[Indonesia, including in the Kelep Watershed, Lombok Island, flood disasters frequently occur. Land use changes and climate variability make this area more vulnerable to floods. This study aims to analyze the distribution and level of flood vulnerability and the dominant factors causing flood vulnerability in the Kelep Watershed. The method used was the weighting of six parameters, namely slope, landform, soil type, rainfall, land use, and river buffer, which were then overlaid using ArcGIS 10.8 software. The results showed that the highly flood-prone areas were spread across all sub-districts in the Kelep watershed, with the highest concentration in Sekotong, Lembar and Southwest Praya sub-districts. The three villages with the highest flood-prone areas are Candi Manik, Sekotong Tengah and Taman Baru. These areas require special attention as they often experience serious impacts due to flooding. Based on the validation test, the RMSE value of 5.95% indicates acceptable accuracy. The resulting flood vulnerability classification map can be used as a flood early warning system or basis for flood risk mitigation and is proposed to be implemented through cross-sector collaboration to improve preparedness and reduce disaster impacts.]]>

<![CDATA[Regional inequality between Lombok and Sumbawa Islands in West Nusa Tenggara remains a persistent development challenge that requires collaborative strategies. This study aims to analyze equitable development strategies by integrating Implementation Theory with the Pentahelix Collaboration model. A qualitative case study design was employed, involving 25 purposively selected stakeholders from government, private sector, academia, community, and media. Data were collected through in-depth interviews, field observations, and document reviews, and analyzed thematically using NVivo 12 Plus, supported by Four Quadrant Analysis and Implementation Theory. The findings show that development disparities are rooted in unequal infrastructure distribution, dominance of tourism and services in Lombok, and dependence on mining in Sumbawa despite its vast agricultural and forestry resources. The analysis highlights four key dimensions: coherence through a shared equitable vision, cognitive participation via inclusive stakeholder collaboration, collective action in leveraging natural resources with cultural embeddedness, and reflective monitoring through participatory evaluation. The study concludes that equitable development in West Nusa Tenggara requires not only economic growth but also fair distribution of benefits, strengthened connectivity, and inclusive governance. Scientifically, this research reinforces the applicability of Implementation Theory in regional development studies and recommends adaptive, evidence-based policies that integrate local cultural values and multi-stakeholder collaboration for sustainable and just outcomes.]]>

<![CDATA[Light spectrum plays a crucial role in photosynthesis and biomass development of marine macroalgae. This study aimed to evaluate the effects of different light spectra on biomass development of Caulerpa lentillifera in controlled cultivation systems. Four LED light treatments (white, red, yellow, and green spectra at 3000 lux intensity) were applied using a completely randomized design with three replications over 30 days. Growth parameters including absolute growth, relative growth, specific growth rate (SGR), and biomass residue were measured at 10-day intervals. Results showed that red light produced the highest absolute growth (0.107±0.004 mg), relative growth (2.39±0.15%), and SGR (0.237±0.015% day⁻¹), followed by white light (0.101±0.015 mg, 2.26±0.34%, 0.224±0.034% day⁻¹). All treatments exhibited biphasic growth patterns with peak biomass on day 10, followed by progressive decline. White light maintained the highest biomass residue (64.4±23.3%), while green light showed the lowest performance across all parameters (39.3±3.7%). The superior growth under red light is attributed to optimal absorption by photosystem II at 680 nm wavelength. This study recommends red light for maximizing short-term biomass production and white light for maintaining long-term stability in C. lentillifera cultivation systems.]]>

<![CDATA[Mytilopsis adamsi, a small filter-feeding bivalve mollusk, has become an invasive species cultivated in Indonesia as natural feed for economically valuable crustaceans. This study determined optimal salinity levels for growth and survival of M. adamsi during larval to early juvenile transition. Using a completely randomized design, four salinity treatments (10, 20, 30, and 40 ppt) were tested with three replicates each. Larvae were reared for 28 days with Nannochloropsis sp. and Pavlova lutheri as feed, developing from 50.4 µm to 140.17 ± 6.12 µm. Treatments at 20 and 30 ppt demonstrated optimal performance with identical specific growth rates (SGR) of 3.90% per day. Survival rates showed no significant difference (p > 0.05) between treatments, ranging from 24.6% to 27.8%, with highest values at 40 ppt (27.8 ± 0.4%). Statistical analysis revealed a quadratic relationship for SGR (y = -0.0014x² + 0.0615x + 3.2576, R² = 0.8753) with theoretical optimum at 22.0 ppt. The optimal salinity range for M. adamsi cultivation is 20–30 ppt based on growth performance. These results provide baseline data for commercial cultivation protocols and environmental management strategies.]]>

<![CDATA[Integrated farming systems (IFS) offer a sustainable approach to optimize agricultural resources and support agro-tourism development in dryland regions. This study aims to analyze farmers' perceptions of IFS and its potential implementation for sustainable agro-tourism in the Batu Lanteh watershed, Sumbawa. Using a descriptive-analytical mixed-methods approach, data were collected through surveys of 30 purposively selected farmers across three villages, complemented by in-depth interviews and field observations. Results indicate that farmers partially adopt IFS practices such as using crop residues as feed, cultivating legumes, and recycling manure but face constraints due to limited agricultural literacy, small land holdings, aging farmers, and inadequate market access. Although economic benefits like increased income and reduced production costs are positively perceived, consistent implementation of long-term ecological practices remains low. The study concludes that enhancing IFS adoption and agro-tourism integration requires targeted technical assistance, farmer education, and improved infrastructure. These efforts can optimize resource use, strengthen environmental conservation, and promote sustainable agro-tourism in dryland contexts.]]>

<![CDATA[Palm sap (Arenga pinnata) plays a crucial role in sustaining local livelihoods and preserving cultural identity in Kekait Village, West Lombok. However, the development of this commodity remains limited by low product quality, inadequate processing technology, and weak integration with the village’s agrotourism sector, resulting in suboptimal economic benefits for the local community. This study aims to formulate a comprehensive development strategy for palm sap–based products to increase value-added and strengthen sustainable agrotourism. A narrative review method was applied by synthesizing primary data from field observations, semi-structured interviews, and community empowerment activities with secondary literature. The data were analyzed descriptively using SWOT analysis to examine key internal and external factors influencing the sector. The results show that technological interventions, such as the use of cabinet dryers and the application of Good Food Handling Practices, significantly enhance product shelf life and compliance with market standards. In addition, institutional strengthening, digital marketing, and the integration of cultural-based educational tourism are effective in expanding market access and improving competitiveness. The scientific contribution of this study lies in offering a holistic upstream–downstream development model grounded in community empowerment, positioning palm sap products not only as economic commodities but also as drivers of cultural preservation, environmental sustainability, and improved community welfare within agrotourism-based rural development.]]>

<![CDATA[Seagrass meadows are among the most productive coastal ecosystems, yet they are estimated to experience annual losses of approximately 7% due to ongoing conflicts between conservation objectives and local livelihood needs. This study maps the evolution of seagrass–ecotourism research from 2016 to 2025 and proposes a regenerative tourism framework tailored to the Indonesian context. A hybrid bibliometric analysis of 235 scientific publications was conducted, complemented by a Systematic Literature Review (SLR) of 27 key articles selected for relevance and methodological rigor. Knowledge structures and thematic clusters were visualized to identify dominant research trends and gaps. The results reveal a paradigm shift from ecology-centered studies toward integrated socio-economic and governance-oriented approaches. Indonesia contributes 41% of global research output, highlighting its role as a major seagrass hotspot and living laboratory for conservation-based tourism. Empirical evidence shows that integrating Regional Public Service Agency (BLUD) governance with Blue Carbon financing mechanisms, as observed in Raja Ampat, has strengthened financial support for seagrass conservation and restoration. Overall, the findings indicate a transition from passive conservation to regenerative management, where ecotourism serves as a strategic financing engine for ecosystem recovery. Integrating Indigenous and Local Knowledge (ILK) with carbon trading schemes is crucial to ensure long-term sustainability and resilience of seagrass ecosystems in the Anthropocene]]>

<![CDATA[Mangrove ecosystems provide essential ecological and socio-economic services that support coastal sustainability, yet their potential has not been fully optimized in ecotourism development. This study aims to identify the roles of mangrove ecosystem services, review effective ecotourism models, and formulate development recommendations for the Tanjung Batu Mangrove Area. A Systematic Literature Review (SLR) following the PRISMA 2020 protocol was conducted, and 52 eligible articles were analyzed using thematic synthesis supported by bibliometric mapping. The findings show that regulating and cultural ecosystem services are the most influential in shaping mangrove ecotourism, particularly through shoreline protection, habitat support, and educational value. Community-based ecotourism (CBE), educational tourism, and conservation-oriented approaches emerge as the most effective models across tropical coastal regions. Successful implementation is determined by ecological integrity, community participation, and supportive governance. For Tanjung Batu, integrating these components offers a strategic framework for enhancing tourism potential while strengthening conservation outcomes. This study recommends applying a hybrid community-based and education-focused ecotourism model supported by governance collaboration to ensure long-term ecological resilience and sustainable coastal development.]]>

<![CDATA[The abundant pineapple waste in East Lombok remains underutilized as a functional food resource and has not been integrated into sustainable agrotourism development, leading to environmental challenges and missed economic opportunities for local communities. This study aims to design a model for converting pineapple waste into functional food products within a zero-waste agrotourism and circular economy framework that supports community-based development. A descriptive qualitative literature review was conducted using reputable journals, BPS statistics, data from agricultural and tourism agencies, and regional planning documents. Thematic analysis identified the bioactive potential of pineapple waste, explored functional product innovations, and formulated integration schemes for agrotourism activities. The results show that pineapple peel, core, and crown contain bromelain, phenolic compounds, and dietary fiber that can be processed into fermented beverages, functional vinegar, peel tea, fiber flour, and high-fiber snacks suitable as agrotourism products. Integrating these products through workshops, demonstrations, tasting sessions, educational tours, and souvenir sales can enhance commodity value, strengthen green destination branding, and support the SDGs. Overall, the utilization of pineapple waste offers a synergistic strategy that links agriculture, food innovation, sustainability, and tourism. The study highlights the need to establish a circular economy–based pineapple agrotourism pilot model supported by product guidelines, food safety standards, innovation facilities, and collaboration among farmers, MSMEs, researchers, and local government.]]>
