Abstract

Vector-borne disease such as Dengue Hemorrghagic (DHF), transmitted by Aedes aegypti and Aedes albopictus, remain a significant public health concern in Indonesia. Controlling these disease often involves insectides; however, the negative impact of chemical insecticides have prompted interest in organic alternatives derived from plants. Certain weeds, including cogon grass (Imperata cylindrica), wild sugarcane (Saccharum spontaneoum), and needle grass (Andropogon aciculatus), have shown potential as botanical insecticides. Research findings showed that weed root extracts significantly affect larval mortality rate of Ae. Aegypti. At 1000 ppm, larval mortality was significantly higher compared to 100 ppm and the control, while treatments of 1 ppm and 10 ppm showed similar results to the control. Probit analysis revealed that I. cylindrica root extract achieved an LC50 of 974.99 ppm within 24 hours, indicating it could kill 50% of Ae. Aegypti larvae. Within 48 hours, the LC50 dropped to 889.20 ppm. Toxicity tests further revealed significant differences in Ae. Aegypti egg-laying abilities when treated with extracts. Analysis of variance yielded p-values of 0.000 for egg hatching within 72 and 96 hours, highlighting significant differences across samples. These findings suggest the extracts influence mosquito reproduction, warranting further studies to assess the quality of egg hatched from larvae exposed to these treatments. The potential of botanical insecticides derived from weeds represents a promising step toward sustainable mosquito control in the fight against vector-borne diseases.

Abstract

Microplastic pollution has become an increasingly worrying global environmental issue. Microplastics are plastic particles measuring less than 5 mm from the degradation of large plastics or using products containing microplastics. Microplastics can enter the human body through contaminated food, water, and air, with feces being one of the indicators of exposure. This study aims to analyze the characteristics and abundance of microplastics in feces in communities on the banks of the Musi River in Palembang City. This study used a descriptive design with laboratory analysis. Fecal samples were collected from 50 respondents selected by purposive sampling based on fish consumption patterns and water sourced from the Musi River. The study was carried out using the microplastic separation method using a solution and particle identification using a stereo microscope and FTIR spectroscopy. The results showed that microplastics were found in all respondents' feces samples, with concentrations ranging from 9-27 particles per gram and an average of 18 particles per gram. The dominant types of microplastic polymers found were Polystyrene (PS), Nylon, Polyvinyl chloride (PVC), Polypropylene (PP), Polyethylene Terephthalate (PET), and Polyethylene (PE). It was concluded that the presence of microplastics in feces indicates significant exposure. Microplastics, such as fragments, fibers, and other particles, were found in people's feces with various shapes, sizes, and colors. The abundance of microplastics in feces indicates contamination, which most likely comes from consuming food and drinks exposed to microplastics. It is recommended that a campaign be carried out to reduce single-use plastic or increase waste processing in riverbank areas.

Abstract

Flooding is one of the causes of environmental damage worldwide. Several things that can affect flooding in urban areas, Palembang experiences periodic flooding problems, especially every rainy season. The data in this article consists of primary data obtained from location surveys in retention ponds, including: documentation, topography, depth of retention ponds and secondary data from related agencies, including: location maps, climatology, regional topography. Palembang City has varying levels of flood vulnerability: high (Jakabaring, Kertapati, Plaju, and Seberang Ulu), medium (Ilir Barat and Sukarame), and low (Alang-Alang Lebar). Lowland areas with poor drainage systems require more attention. Retention ponds play an important role in managing rainwater runoff, such as the Jakabaring Sports Hall (200,000 m²), Ogan Permai Indah (22,217 m²), and Brimob Demang Lebar Daun (30,000 m²). The city's topography, which is mostly flat and low, especially around the Musi River, further increases the risk of flooding.

Abstract

Forest fires are a common ecosystem disturbance globally and have a significant impact on the environment and human life. Ecologically, fires result in decreased land productivity, loss of forest economic value, and threats to biodiversity. The study was conducted quantitatively and qualitatively with secondary and primary data. The data shows fluctuations in the number of hotspots and the area of burned land from 2019 to 2024. Major fires occurred in 2019 and 2023, while a significant decline was seen in 2020 and 2024. This decline reflects the effectiveness of fire mitigation involving the government and the community. Efforts that have been made to reduce the risk of forest and land fires in OKI Regency include peatland rewetting, community education, peatland-based economic empowerment, joint patrols, and the active role of the Fire Aware Community (MAPI) group. The use of satellite-based monitoring technology is also an important step in fire monitoring and mitigation. Preventing forest and land fires in the future requires a comprehensive and sustainable approach, including law enforcement against illegal land burning, increasing patrols, and strengthening community education. Collaboration between stakeholders such as BPBD, local governments, communities, and the private sector is very important to maintain the stability of forest and land fire reduction in the OKI region.

Abstract

Coal mining activities carried out openly can have a negative impact on the environment. One of the environmental damages that occurs is the loss of habitat for soil-level insects. This research was conducted to identify the diversity of soil surface insect species in post-coal mining land of PT. Bukit Asam Tbk Tanjung Enim IUP Banko Barat at various ages of reclamation. Soil surface insect samples were collected using the pitfall trap method which was carried out for 1x24 hours. The results showed that the highest presence of soil surface insect species occurred in aged 6 years with a total of 128 individuals and was dominated by the order Hymenoptera. The species diversity index in post-coal mining land aged 6 years, namely 1.51, is classified as moderate. The lowest presence of soil surface insects occurred in aged 2 years with a total of 24 individuals. The species diversity index in post-coal mining land aged 2 years, namely 0.85, is relatively low. Thus, the research results show that the diversity of surface soil insects is influenced by the age of reclamation. The longer the land is managed, the higher the index of diversity of soil surface insect species in post-coal mining land.

Abstract

This study examines the effectiveness of Ganoderma sp. in decomposing lignin in herbaceous plants. The study was conducted in a greenhouse at the Faculty of Agriculture, Sriwijaya University, with temperatures ranging from 28-30oC and humidity reaching 70-80%. The test plants consisted of uwi (Dioscorea alata) and talas (Colocasia esculenta), and oil palm seedlings were used as a comparison. The parameters observed included the level of decay and mycelium viability after inoculation. The results showed that the highest level of decay occurred in taro, reaching 65.22% in sterilized soil and 52.56% in unsterilized soil, while uwi experienced decay of 33.9% and 33.03%. The viability of Ganoderma sp. mycelium remained high (>70%) in all treatments. This indicates a strong ability to adapt to various environmental conditions. Thus, the study shows that the ligninase activity of Ganoderma sp. contributes significantly to decomposition without reducing the viability of the Ganoderma sp.
