Abstract

Sampah plastik merupakan masalah penting yang terus meningkat setiap tahunnya. Ini adalah ancaman bagi ekosistem laut di seluruh dunia. Penelitian telah menunjukkan bahwa benda-benda plastik, seperti mikroplastik, hadir di air laut dan lingkungan lainnya. Mikroplastik dapat dikonsumsi oleh ikan, kemudian ikan dikonsumsi oleh manusia. Sampah plastik juga sangat mengganggu jalur transportasi laut, di mana banyak sampah padat ditemukan di jalur kapal dan perahu nelayan. Kematian terumbu karang dan lamun dapat berdampak signifikan terhadap lingkungan laut. Dengan menekan jumlah produksi plastik yang dihasilkan di darat maka sampah tidak akan berakhir di lautan kita dan tidak menyebapkan kerusakan lingkungan yang ada di laut melalui Bank Sampah mengolah sampah plastik menjadi barang kreatif yang kemudian dijual menjadikan suatu sumber ekonomi bagi kehidupan di sekitarnya, serta penggunaan kantong kain pengganti kantong plastik.

Abstract

Stunting is a growth and development disorder in children caused by chronic malnutrition and recurrent infections, and is characterized by height or height below normal. The short-term impact of stunting can be reduced learning ability due to lack of cognitive development. Stunting is a nutritional problem caused by multifactors, namely social factors, biological factors and environmental factors. Environmental conditions such as poor water and sanitation are indirect factors that cause stunting in children. This research aims to analyze the factors that influence stunting in toddlers. The research design used was the literature review method. A total of 20 articles from the Google Scholar database were reviewed in this research with criteria published in 2019-2023. This study was prepared using a narrative method. Articles were grouped with similar results to answer research questions. This study found that theoretically, sanitation and water quality have an influence on the occurrence of stunting events. Conclusion: In overcoming stunting, environmental factors must be considered to improve the quality of drinking water so that it meets health standards and is suitable and safe for consumption. It is recommended to maintain good sanitation to prevent the emergence of disease outbreaks which increase the number of illnesses and deaths.

Abstract

Rivers play an important role in supporting people's lives. However, poor river water quality due to pollution has a significant impact on the survival of coastal communities and the condition of the surrounding environment. To overcome water pollution, it is important to implement stricter regulations that are regulated in Law no. 32 of 2009 supplemented by Republic of Indonesia Government Regulation Number 22 of 2021. The research carried out was quantitative descriptive in nature, highlighting the impact on the water quality of the Batang Arau river from examining BOD, COD and TSS, which are river water pollution parameters. The research results show that in 2023, the results of examining COD parameters in the upstream river area will exceed the set quality standard limit, namely 25 mg/L. The recorded value reached 87.3 mg/L, which indicates the presence of very high levels of organic chemicals in these waters. In 2024, inspection results show significant improvements in the water quality of the Batang Arau River. It was concluded that the water quality of the Batang Arau river shows a positive trend. The pollution conditions that occurred in 2023, especially in the COD and BOD parameters in the upstream river, have been successfully improved by 2024. This shows the success of efforts to improve environmental quality carried out in the river area.

Abstract

The environment is a unity of space that includes all natural elements, including living things and the interactions between these elements. In recent decades, waste pollution, especially microplastics, has become a major threat to aquatic ecosystems and human health. Microplastics are small plastic particles that are dispersed in various aquatic ecosystems and can accumulate in the food chain. This study aims to assess the abundance of microplastics in West Sumatra waters, especially in coastal areas, rivers and lakes. The method used in this research is literature review. Based on the literature review, microplastics were found in sediments and marine organisms, such as fish contaminated by microplastics, with the dominant type being fibers. Some areas, such as Carocok Beach, Bungus Bay and Purus Beach, show high abundance of microplastics, which is associated with human activities and poor waste management. These findings emphasize the importance of better waste management to reduce microplastic pollution. This study also provides a clearer picture of the distribution of microplastics, their impacts on aquatic ecosystems and human health, and suggests more effective plastic waste management policies in West Sumatra to maintain the sustainability of aquatic ecosystems and public health.

Abstract

Evaluation of student abilities in Biology subjects often faces challenges in ensuring that the instruments used actually measure what they are supposed to measure. The data analysis used is the Rasch model, which is part of item response theory, offering a more accurate approach in analyzing evaluation data. This model allows the identification of items that are inappropriate or too difficult, as well as providing more in-depth information about individual student abilities.  Through analysis of instruments and question items from 30 multiple choice questions that emphasize critical thinking skills, the aim of this research is to assess the quality of Biology questions for class X SMA. Testing was carried out using WinStep software and Rasch modeling analysis on 166 students from five high schools/vocational schools. The research method used is quantitative. The results of the instrument investigation show that the issue has very good dependability and the unidimensionality of the instrument is indicated by unexplained changes in the first differentiation. These results show that the Rasch test can help educators in selecting questions that meet the evaluation criteria and contribute to improving the quality of national education. The implications of this research are By applying the Rasch Model, educators can develop more accurate and fair evaluation tools, which are able to identify individual student difficulties and strengths.
