Abstract

Sungai Jembayan merupakan salah satu sungai pendukung kegiatan masyarakat sehari-hari, pertanian dan perkebunan di sebagian Kecamatan Loa Kulu, Kutai Kartanegara. Masuknya unsur nitrogen dan fosfor dari aktivitas di sekitarnya ke perairan akan menimbulkan dampak lingkungan seperti eutrofikasi, perubahan struktur dan komunitas alga yang pada akhirnya mengganggu kualitas perairan. Tujuan penelitian ini untuk mengetahui perbedaan struktur dan komposisi fitoplankton penyusun ekosistem perairan Sungai Jembayan, status trofik, dan hubungan antara faktor-faktor yang mempengaruhinya. Penelitian dilakukan dengan teknik survey sampling di 3 lokasi yakni bagian hulu, tengah dan hilir. Parameter air yang diukur secara insitu adalah suhu, kecerahan dan pH, sedangkan parameter kekeruhan, oksigen terlarut, Nitrat, Fosfat,sedangkan analisis fitoplankton dan kandungan Klorofil-a dilakukan analisis di Laboratorium. Status trofik indeks perairan dihitung menggunakan metode Trophic State Index (TSI Carlson). Hasil analisis TSI diperoleh kisaran nilai TSI antara 38,46-55,00 dengan rata-rata 50,18 sehingga dapat dinyatakan bahwa sepanjang segmentasi Sungai Jembayan (dari daerah hulu-hilir) berada pada tingkatan eutrofik. Struktur komunitas fitoplankton didominasi oleh kelas Cyanophyceae dan Bacillariophyceae serta terdapat jenis Nitzschia sp yang merupakan fitoplankton jenis Harmful Algal Blooms (HABs). Berdasarkan nilai indeks keanekaragamannya menunjukkan penyebaran individu dan kestabilan komunitas dalam kategori tinggi. Nilai dominansi jenis serta jumlah individu tiap jenis relatif sama

Abstract

Rivers are open waters that flow and get input from various human activity discharges such as; settlements, industries that will result in changes in physical, chemical and biological factors in the waters. This can cause damage, disturbance and danger to living things that depend on water resources. This research was conducted in March 2022 in Karang Asam Besar River, Samarinda City, East Kalimantan Province. This study aims to determine the difference in Nitrogen and Phosphate content at high and low tide in Karang Asam Besar River, Samarinda City. Total Nitrogen at the five stations in the Karang Asam Besar River at average values ranged from 13.02-16.45 mg/L and at low tide ranged from 13.20-20.78 mg/L, the highest Nitrogen value at high tide was at Station 2 and the lowest at Station 4, while the highest Nitrogen at low tide was at Station 4 and the lowest at Station 1. Total Phosphate at the five stations at high tide ranged from 0.14-0.19 mg/L and at low tide ranged from 0.18-0.23 mg/L, the highest Total Phosphate value at high tide was at Station 1 and the lowest at Station 4, while the highest Phosphate at low tide was at Station 4 and the lowest at Stations 1, 3 and 5. Nitrogen compounds at each station in the Karang Asam Besar river based on the quality standards of PP No. 82 of 2001, Ammonia has exceeded the quality standard threshold which exceeds 0.5 mg/L. Nitrite does not exceed the quality standard threshold of less than 0.06 mg/L. Nitrate does not exceed the quality standard threshold value of less than 10 mg/L. Phosphate is still within normal levels and there is no pollution by phosphate compounds.

Abstract

This study aims to identify and analyze the relationship between the level of perception and the level of community participation in household waste management in Loa Bakung Village. The research employed both quantitative and qualitative methods using questionnaires, literature review, and direct observation. Respondents were selected using purposive sampling with a total of 80 participants. The results show a p-value of 0.001 ≤ α = 0.05 with a correlation coefficient of 0.361, indicating that there is a correlation between perception and participation in waste management, although the relationship is weak and positive. Qualitative findings reveal that waste banks can help reduce waste volume (66.3%) and highlight the importance of separating organic and inorganic waste (61.3%). However, actual participation remains limited, with only a small proportion of respondents regularly practicing waste sorting, composting, or recycling. The suggested recommendation is the need for awareness programs through KIE (Communicative, Implementation, and Education) approaches and regular monitoring.
