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

Aim: This study aims to assess the entire process of septage management comprising regulation, operational procedures, finance, community involvement, and water quality analysis to maximize the initial and hugest human fecal sludge treatment called Faecal Sludge Treatment Plant (IPLT) in Yogyakarta. Methodology and Results: The Modified EHRA (Environmental Health Risk Assessment) method was applied which focused only on wastewater treatment aspect. Several regulations including standard quality methods (SNI) were utilized and made a comparison between baseline rules and obtained results. Furthermore, quality assessment was accomplished by observation and interview. The results showed that the human sector needs to improve not only the amount of operators but also urgently put up protective personal equipment during the suction process. The dissemination of attractive information about sludge suction service done by PUPKP as a representation of the local government among the dwellers ought to upgrade a lot. Technologies employed which are carriage transportation and vacuum machine, are good enough. Contrarily, septage treatment plants require extra-effort to enhance it as most water quality parameters barely meet the standard quality. BOD, COD, ammonia, total coliform, oil and grease do not meet the third class of water quality (Government Regulation of Republic of Indonesia No. 82/2001). Subsequently, the effectiveness of each unit i.e. anaerobic tank and stabilization ponds are under 50% and the loading rate has a maximum capacity of 87.5m3/day, and 60m3/day minimum capacity. Conclusion, significance and impact of study: Therefore, almost all aspects of septage management in Bantul Yogyakarta are required to improve

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.
