Abstract

Water quality assessment in the tsunami-affected areas conducted in Meuraxa and Kutaradja sub-districts in the area of Banda Aceh City. Water samples were collected in October 2006 from dug wells of tsunami-affected areas. These were characterized for various physical and chemical parameters. Water quality in the selected areas has shown that the surface water was contaminated due to the tsunami. Total Dissolved Solid, Total Suspended Solid, Acidity, and salinity were high in the affected areas indicating saline water intrusion into surface water tables. Dug wells in the highly affected locations showed higher values of heavy metal ions like Mn, Pb, Cu, Fe, Zn, and Cu compared to the reference points. No ion Hg was found in all samples. Keywords: Banda Aceh, heavy metals, tsunami, water quality

Abstract

Wetlands, as part of ecological technology commonly applied in wastewater treatment, are an innovative solution in environmental protection and restoration. Floating Treatment Wetland Systems (FTWs) are a new concept in wastewater treatment using macrophytes rooted in aquatic plants modified as floating systems. Use of a local aquatic plant that is often found and thrives as a weed in rice fields throughout Aceh, namely Actinoscirpusgrossus. Variables varied according to plant height, pond I 90cm – 150cm, pond II 50cm – 90cm and pond III control without plants, influent and effluent were analyzed every two weeks for 18 weeks with 9 analytical sampling times. The results of the domestic wastewater experimental parameter test showed that the average degradation efficiency (%DE) was pH 6.92, total suspended solid (TSS): 98.28%, biological oxygen demand (BOD): 97.77% and chemical oxygen demand (COD): 98.30%, very significant results. The management process of regularly cutting plants is an important part for the Actinoscirpusgrossus aquatic plant to achieve optimum results in processing wastewater, namely for 112 days with a maximum plant growth height of 165cm and 173cm for the two variations of the experimental ponds.

Abstract

This study explores the development of a character-building model that integrates the Merdeka Curriculum and School-Driven Program to foster religious and social care values among high school students in Banda Aceh. Using a qualitative approach, data was collected through observations, in-depth interviews, and documentation analysis, involving school principals, teachers, students, and community members from four high schools in Banda Aceh. Triangulation of sources and techniques ensured data validity. The findings show that each school employs unique character-building strategies aligned with its vision and mission. The study emphasizes the importance of proactive school leadership, teacher engagement, and community collaboration in successful character education. To address challenges such as cultural differences, student readiness, and resource limitations, the Busi (Islamic School Culture) model was developed. This model integrates religious values and social activities, enhancing students discipline, empathy, and social skills. The implementation of the Busi model led to significant improvements in students moral and social development. The study underscores the need for integrating religious and social values into the curriculum and fostering collaboration between schools, families, and communities to achieve holistic character education.

Abstract

Pelaksanaan Merdeka Belajar Kampus Merdeka (MBKM) tahun 2022 telah dilakukan pada bulan Agustus semester ganjil tahun 2022-2023. Peserta yang mengikuti program ini sebanyak 241 mahasiswa skema MBKM ISS dan 2.318 mahasiswa skema MBKM USK Unggul yang merupakan salah satu inovasi yang dikemas oleh USK dalam meningkatkan keikutsertaan mahasiswa MBKM. Pelaksanaan MBKM ini melibatkan 116 mitra skema ISS dan 486 mitra skema USK Unggul. Khususnya pada kegiatan MBKM Asistensi Mengajar diikuti oleh 1.252 mahasiswa, sehingga survey pada kegiatan ini dilakukan secara bertahap oleh tim universitas. Adapun tujuan pemanfaatan metode survei sebagai strategi evaluasi kegiatan ini adalah untuk dapat memastikan bahwa kegiatan asistensi mengajar di lapangan berjalan sesuai panduan MBKM USK tahun 2020. Metode survei dilakukan melalui pengamatan secara langsung kepada mitra kegiatan asistensi mengajar yaitu melalui wawancara dan penyebaran kuesioner kepada responden menggunakan google forms. Strategi evaluasi kegiatan dilakukan kepada semua yang terlibat, yaitu peserta didik, dosen pembimbing lapangan (DPL) dan sekolah sebagai mitra. Hasil pemanfaatan metode ini secara umum menjelaskan bahwa kegiatan asistensi mengajar telah berjalan tertib, aman, dan lancar tanpa adanya kendala yang berarti. Mahasiswa mejalankan tugas dan kegiatan secara terstruktur didampingi oleh pembimbing lapangan serta dosen. Namun demikian, masih ditemukan beberapa kasus minor (kecil) yang terjadi di beberapa lokasi tertentu dan dapat ditanggulangi segera pada saat pelaksanaan kegiatan. Kasus-kasus minor yang tidak dominan dan tidak terjadi di seluruh lokasi tersebut dipelajari dan diperbaiki oleh semua pemangku kepentingan termasuk pimpinan universitas sehingga kendala pada pelaksanaan kegiatan asistensi mengajar saat ini, menjadi pembelajaran perbaikan lebih baik untuk kegiatan ke depan.

Abstract

This study aims to evaluate the effectiveness of the leachate treatment plant at the Blang Bintang Regional landfill and analyze its impact on the water quality of the Krueng Uteun Siblah River. The method used is a comparative analysis of leachate quality monitoring data (influent and effluent) from the landfill from 2021 to 2025. The results showed that the treatment plant successfully reduced the concentration of pollutants in leachate, with an average efficiency percentage for the parameters of Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), and Total Suspended Solids (TSS) Nitrate, NH₃, Cd, Fe were 23.87%, 64.15%, 50.53%, 35.26%, 62.19%, 71.05%, and 40.18%, respectively. However, effluent values for COD and BOD parameters still exceed the established quality standards. Further analysis of the Krueng Uteun Siblah River revealed a significant decline in water quality immediately after the leachate outfall point, marked by a spike in BOD (27.4-30 mg/L), COD (51.17-62 mg/L), and iron concentration (3.65-4.21 mg/L) that exceeded quality standards, as well as a drastic decrease in Dissolved Oxygen (DO) levels to 3.5 mg/L improving the performance of leachate treatment facilities and implementing stricter management strategies are absolutely necessary to protect the aquatic ecosystem around the landfill.

Abstract

Abstract: A continuous assessment of river water quality is a crucial aspect of water resources management and environmental protection. This research aims to assess the water quality status in Krueng Peusangan River that crosses Bireuen, Bener Meriah and Aceh Tengah Regency, Aceh Province, using the pollution index (IP) method. The water quality data used in this research is secondary data from monitoring results at several sampling locations from upstream to downstream over 10 (ten) years period from 2016 to 2025. Key parameters analyzed include physical, chemical, and biological parameters, such as pH, temperature, Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), nitrate, nitrite, phosphate, and bacteriological (Total Coliform). The pollution index calculation results show fluctuations in water quality status from year to year. In 2016-2018 and 2020-2021, the river was categorized as moderately polluted with IP values ranging from 5.829 to 8.898. Meanwhile, in 2019 and the 2022-2025 period, water quality experienced significant improvement and remained stable in the lightly polluted category, with IP values decreasing and remaining in the range of 1.243 to 3.378. This trend change needs to be observed by considering the change in the number of parameters for the IP calculation from 21 parameters (2016-2021) to 9 parameters (2022-2025). This indicates that the use of a more comprehensive parameter set (21 parameters) can provide higher analytical resolution and be sensitive to fluctuations in various pollutants. Therefore, parameter simplification has the potential to affect the interpretation of long-term pollution trends. Abstrak: Penilaian kualitas air sungai secara berkelanjutan merupakan aspek krusial dalam manajemen sumber daya air dan perlindungan lingkungan. Penelitian ini bertujuan untuk menentukan status kualitas air Sungai Krueng Peusangan yang melintasi Kabupaten Bireuen, Bener Meriah dan Aceh Tengah, Provinsi Aceh, dengan menggunakan metode Indeks Pencemaran (IP). Data kualitas air yang digunakan merupakan data sekunder hasil pemantauan pada beberapa titik sampling dari hulu hingga hilir selama periode 10 (sepuluh) tahun mulai tahun 2016 hingga 2025. Parameter kunci yang dianalisis meliputi parameter fisika, kimia, dan biologis, seperti pH, suhu, Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), nitrat, nitrit, fosfat, serta bakteriologis (Total Coliform). Hasil perhitungan Indeks Pencemaran menunjukkan fluktuasi status kualitas air dari tahun ke tahun. Pada tahun 2016, 2017, 2018, 2020, dan 2021, sungai berada dalam kategori tercemar sedang dengan nilai IP berkisar antara 5,829 hingga 8,898. Sementara itu, pada tahun 2019 dan periode 2022-2025, kualitas air mengalami perbaikan yang signifikan dan stabil masuk dalam kategori tercemar ringan, dengan nilai IP menurun dan bertahan di kisaran 1,243 hingga 3,378. Perubahan tren ini perlu dicermati dengan mempertimbangkan perubahan jumlah parameter untuk perhitungan IP dari 21 parameter (2016-2021) menjadi 9 parameter (2022-2025). Hal ini mengindikasikan bahwa penggunaan parameter yang lebih komprehensif, yaitu 21 parameter, dapat memberikan resolusi analitik yang lebih tinggi dan sensitif terhadap fluktuasi berbagai polutan, sehingga penyederhanaan parameter berpotensi memengaruhi interpretasi tren pencemaran jangka panjang.
