The length-weight relationship of fish and the condition factor provides an overview of the fish growth conditions in the river. The purpose of this study was to determine the length-weight relationship and factor condition of five fish species in the Suwi River wetlands. The method of catching fish used gill nets, ceiling nets, fishing rods, traps, and other nets. The research was conducted for to months in the Suwi river wetlands. The results the length-weight relationship of five fish were varied, Ompok bimaculatus had b value 2,93, Helostoma temminckii (b Â value 2.15), Mystus nemurus Â (b value 2,62), and Channa) micropeltes (b 2.61) which indicated a negative allometric growth pattern. Meanwhile Leptobarbus hoevenii (b 3.12) was a positive allometric growth pattern. Negative allometric indicates growth in length faster than weight growth, thus the physical shape looks flattened, while positive allometric indicates growth in fish length slower than growth in fish weight. Based on the relative weight (Wr) of Ompok bimaculatus 101.28 Â± 19.13, Helostoma temminckii 101.05 Â± 15.51, Mystus nemurus 100.95 Â± 14.84, Channa micropeltes 101.09 Â± 14.14, Leptobarbus hoevenii 103.71 Â± 34.57. Condition factor above 100, indicates sufficient food availability or low predator density

The Important Ecosystem Area of Mesangat Suwi Wetlands has a total area of around 14,722.69 ha located in East Kutai Regency, East Kalimantan. These wetlands have a strategic role as a regulators of the upstream water system, a source of freshwater fisheries, and a habitat for important protected animals. This study aimed to determine the rate of suspended sediment transport and river water quality. The study was conducted in two stages, the first was data and sample collection in the field, and the second was laboratory testing. The results of the study showed that the river water discharge and TSS in the Suwi and Masangat Rivers at the study location were directly proportional to the height of suspended sediment. The total average of suspended sediment in Suwi was smaller, it's 0.79 tons/year compared to Masangat at 2.64 tons/year. suspended sediment grains could settle and become bottom sediment. The rate of sedimentation in the river would accelerate the shallowing process which affected the wetlands ecosystem. The reduction in vegetated or forested areas in the Masangat wetlands was due to high human activity compared to Suwi. Currently, the water quality in the study areas, including COD, BOD, TDS, and TSS, is generally still below the standard quality threshold and is categorized as class two, namely water that can be used for freshwater fish farming, recreational facilities, livestock farming, and can be used to irrigate crops or rice fields.

The conservation and protected areas within the Essential Ecological Areas of the Mesangat-Suwi Wetlands are ecologically significant due to their high biodiversity, local community fishing resources, and habitat for endangered species. The distinctiveness of the Suwi Wetlands as a habitat for proboscis monkeys (Nasalis larvatus) and Crocodylus siamensis enhances the prospects for sustainable ecotourism through natural attractions. This study references the evaluation of natural tourism attractions' potential and the carrying capacity of both biotic and abiotic environments. Of the fourteen prospective variables evaluated, nine exhibit significant potential: natural attractions, market potential, surrounding circumstances, climate, accommodation, supporting infrastructure, security, area carrying capacity, and market share. The Physical Carrying Capacity (PCC) for the maximum number of visitors is 80 individuals per day, whereas the Real Carrying Capacity (RCC) is 3 individuals per day. The quantity of visitors is consistent with the condition of biophysical characteristics. Wetlands of significant conservation significance must be safeguarded via sustainable ecotourism approaches. Conservation initiatives beyond forested regions should focus on cultivating ecotourism potential to guarantee long-term environmental sustainability.

Landscape transformation driven by rapid urbanization is a primary determinant of microclimate change in peri-urban regions. This study aims to analyze the spatiotemporal dynamics of land surface temperature (LST) and its relationship with vegetation density (Normalized Difference Vegetation Index/NDVI) in the Southern Jember landscape. Utilizing Landsat 7 ETM+ and Landsat 8 OLI/TIRS imagery from 2001, 2013, and 2025, this research evaluates the impact of land cover changes on the regional thermal regime and vegetation index variability. The results reveal a fundamental landscape transition, where the dominance of paddy fields shrank drastically from 66.400 ha (2001) to 13.800 ha (2025), replaced by a massive expansion of settlements reaching 82,900 ha. This shift triggered a significant surface urban heat island (SUHI) phenomenon. Settlement areas recorded an extreme maximum LST of 38,1°C in 2025, a sharp increase compared to the initial study period. Spectral analysis confirms that the rise in LST has a negative correlation with NDVI. This evidence suggests that the loss of vegetation biomass and the increase in impervious surfaces due to uncontrolled urbanization are the primary drivers of environmental warming in South Jember. These findings underscore the urgency of climate-mitigation-based spatial planning strategies for regional sustainability.
