Abstract

Waste is a crucial issue with far-reaching impacts on the environment, public health, and economy. The Putri Cempo landfill receives waste from Surakarta City. Waste can pollute the river near the landfill, given the location of the river that adjoins and is close to residential areas. The purpose of this research was to analyze the river water quality around the Putri Cempo landfill for heavy metals Pb and Mn. The research was conducted by taking samples directly from the river and then analyzing the heavy metal content. The results were compared with river water quality standards according to Indonesian Government Regulation 22/2021. The results showed that the Pb content in river was -0.02392344 mg/L and Mn was 4.206021703 mg/L. From these results, the Pb content in the river did not exceed the quality standard limit, whereas the Mn content exceeded the quality standard limit. It can be concluded that the river water around Putri Cempo landfill has been contaminated with Mn. Heavy metals in high levels can harm living things and the environment, can cause death to aquatic biota and plants, disease in humans, degrade water quality and damage river aesthetics. Further evaluation of stakeholders is required to address heavy metal pollution

Abstract. Rahmadhani SE, Salsabila S, Andrianto R, Rosyida SH, Ainia Q, Dewangga A, Setyawan AD. 2025. Diversity and potential invasiveness of insects in agricultural landscapes of Wonosobo, Central Java, Indonesia. Asian J Agric 9: 663-670. Altitude and microclimatic variation act as key ecological filters that shape species diversity, community structure, and invasion potential altitude, microclimate, and land-use intensity jointly structure insect communities in the agricultural landscapes of Wonosobo, Central Java, Indonesia. Surveys across lowland Karangsambung (621 masl), mid-elevation Blederan (969 masl), and highland Sembungan (2,056 masl) recorded 57 species from 31 families, revealing clear diversity gradients. Species richness and functional balance peaked at mid-elevation, where moderate temperatures and heterogeneous vegetation supported diverse herbivores, predators, and pollinators. Lowland sites retained high diversity driven by warm conditions and productive cropping systems. In contrast, highland assemblages were simplified and dominated by synanthropic Diptera (Musca domestica, Leucostoma simplex), reflecting harsh climatic filters and nutrient-enriched soils. NMDS-envfit analyses highlighted altitude, temperature, illumination, and wind as the main determinants of community structure. Invasiveness remained low overall, but disturbance-tolerant taxa increased with elevation. These findings emphasize the importance of vegetation heterogeneity, microclimate buffering, and biological control in sustaining ecological stability. As climate warming accelerates, mid-elevation agroecosystems may become critical resilience zones for conserving biodiversity and maintaining agricultural sustainability.
