Abstract

AbstrakMikroplastik adalah partikel berukuran kurang dari 5 mm yang ditemukan di berbagai media, mulai dari tanah, air, hingga udara. Penelitian tentang mikroplastik banyak berfokus pada media air dan tanah, sedangkan penelitian tentang mikroplastik di udara  Indonesia masih jarang. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis keberadaan mikroplastik di udara ambien sekitar Tempat Pembuangan Akhir (TPA) Piyungan, Yogyakarta. Sampel udara diambil menggunakan High Volume Air Sampler (HVAS) selama 24 jam dan diperiksa secara visual menggunakan mikroskop, Scaning Electron Microscope (SEM) kemudaian dianalisis dengan Spektroskopi Infra merah Transformasi Fourier (FTIR). Hasil penelitian menunjukkan adanya kelimpahan partikel mikroplastik dalam bentuk fragmen, film, dan fiber dengan berbagai warna terutama warna hitam. Mikroplatik ditemukan dalam semua partikel yang dianalisa, termasuk pada Total Suspended Particulate (TSP), Particulate Matter 10 µm (PM10) dan Particulate Matter 2,5 µm (PM2,5). Penelitian ini menunjukkan kelimpahan jenis, warna dan potensi dugaan keberadaan mikroplastik dalam ukuran partikel yang lebih halus sehingga dapat menjadi dasar penelitian lebih lanjut mengenai mikroplastik yang dapat terhirup dan berdampak pada kesehatan.Kata kunci : mikroplastik, sampah padat, partikulat di udara

Abstract

Many urban cities in Indonesia face critical challenges such as limited green open spaces, declining environmental quality, and spatial pressure driven by rapid population growth. These conditions threaten urban environmental resilience, particularly in maintaining quality of life and sustainable resource use. This study aims to formulate adaptive green infrastructure planning strategies for the Baciro historical neighbourhood in Yogyakarta to enhance environmental quality while preserving the area’s cultural identity. A qualitative case study approach was employed, combining spatial planning documents, field observations, and stakeholder interviews. The findings indicate that despite limited open spaces, Baciro offers significant opportunities for green infrastructure development through the utilization of residual and vertical spaces, including narrow alleys, riverbanks, and commercial building façades. Proposed strategies include the implementation of vertical gardens, green corridors, revitalized riverfronts, and pedestrian-friendly green streets. These interventions contribute ecological functions—such as water infiltration, microclimate regulation, and air quality improvement—while also strengthening social cohesion through community participation. Furthermore, integrating green infrastructure with the Transit Oriented Development (TOD) concept expands its role in promoting sustainable mobility and liveable urban spaces. This research demonstrates that green infrastructure can serve as a strategic instrument for achieving urban environmental resilience while safeguarding historical heritage in the face of urbanization pressures. The results provide insights and practical implications for planning similar historic neighbourhoods across Indonesian cities that encounter comparable spatial and environmental challenges.

Abstract

Microplastics, recognized as emerging contaminants, have been detected in numerous rivers globally. This study focuses on the Ciliwung River in Jakarta, examining the influence of seasonal variations—specifically the rainy and dry seasons—on microplastics' concentration, types, and colors. Sampling was conducted during November 2022 (dry season) and March 2023 (wet season) using a plankton net for water (10 liters) and an Ekman grab sampler for sediment (400 mililiters). Microplastic abundance was analyzed following the National Oceanic and Atmospheric Administration (NOAA) adaptation method, and their material characteristics were identified using Fourier Transform Infrared Spectroscopy (FTIR) testing. Results revealed a notable seasonal impact: in the dry season, average microplastic abundance was 530 particles/liter in water and 859 particles/100 grams in sediment, whereas, in the wet season, these figures rose to 1,111 particles/ liter and 1,583 particles/100 grams, respectively. Fragments were the predominant type of microplastics, and black was the dominant color in both seasons. This consistency suggests similar sources and activities contributing year-round to microplastic pollution in the Ciliwung River.

Abstract

Kualitas udara tidak hanya dinilai dari parameter gas dan partikulat, tetapi juga dari indikator mikrobiologi, karena bioaerosol yang mengandung bakteri dan jamur dapat terhirup langsung serta menyebabkan dampak kesehatan yang serius seperti infeksi saluran pernapas atas (ISPA), alergi, hingga pneumonia. Udara merupakan elemen penting bagi kehidupan manusia dan makhluk hidup lain, namun kualitasnya semakin terancam akibat aktivitas manusia, industrialisasi, dan dinamika lingkungan. Penelitian ini bertujuan menilai kualitas bakteriologi udara di permukiman Dusun Lendang Batu yang berdekatan dengan Tempat Pembuangan Akhir (TPA) Jugil, Kabupaten Lombok Utara, serta membandingkan kualitas udara dalam ruangan dan luar ruangan dengan standar kesehatan yang berlaku. Metode penelitian menggunakan pendekatan kuantitatif deskriptif, dengan pengambilan sampel di tiga titik berbeda. Hasil pengukuran menunjukkan bahwa kualitas udara luar ruangan memiliki angka maksimum 6.710 CFU/m³ pada titik kedua dan minimum 2.931 CFU/m³ pada titik pertama. Sementara itu, udara dalam ruangan menunjukkan angka maksimum 3.567 CFU/m³ pada titik pertama dan minimum 2.366 CFU/m³ pada titik ketiga. Kedua hasil tersebut melebihi standar baku mutu yang ditetapkan dalam Kepmenkes No. 1405/MENKES/SK/XI/2004 dan Permenkes No. 1077/Menkes/Per/VIII/2011, yaitu 200–500 CFU/m³. Hasil uji korelasi Rank Spearman menunjukkan koefisien -0,500 dengan nilai Sig. 0,667 > 0,05. Hal ini menandakan tidak terdapat hubungan signifikan antara kualitas bakteriologis udara dalam dan luar ruangan.

Abstract

This study aimed to analyze the abundance and morphology of airborne microorganisms in the Environmental Engineering Laboratory and to relate their distribution to differences in room conditions and sampling time. Sampling was conducted in two rooms, Room A and Room B, during the morning and afternoon using a microbiological air sampler with Nutrient Agar (NA), Potato Dextrose Agar (PDA), and Plate Count Agar (PCA) media. Statistical analysis showed that room conditions strongly influenced the distribution of airborne microorganisms and were also affected by indoor airflow patterns. The findings revealed higher concentrations in Room B than in Room A (morning averages: 60.75 vs. 23.75 CFU/m³; afternoon averages: 44.5 vs. 24.25 CFU/m³), with a statistically significant difference (Mann–Whitney, p-value < 0.05). These results indicate that optimizing airflow direction, scheduling cleaning activities, and conducting routine bioaerosol monitoring are necessary as indicators of control performance. Morphological analysis identified Gram-positive bacteria such as Staphylococcus and Bacillus, as well as fungi such as Aspergillus and Trichoderma, all of which may affect health and indoor air quality. This study underscores the importance of laboratory indoor air quality management in reducing health risks associated with airborne microorganisms.
