Abstract
Kegiatan Pengerukan yang dilaksanakan di alur masuk dermaga, dermaga, maupun canal water intake PLTU Lontar akan berdampak pada penurunan kualitas air laut karena peningkatan kekeruhan dan zat padat tersuspensi. Kajian aspek lingkungan dan sosial perlu dilakukan pada wilayah studi yang merupakan daerah atau ruang yang digunakan sebagai tempat kehidupan masyarakat yang diperkirakan akan terkena dampak dari kegiatan pengerukan. Analisa yang dilakukan pada penelitian ini adalah analisa pengaruh kegiatan pengerukan terhadap kegiatan masyarakat dan lingkungan dengan menggunakan metode kuantitatif dengan analisis statistik deskriptif. Jenis statistik deskriptif yang digunakan adalah perhitungan deskriptif persentase dan tabulasi silang (crosstab) dan uji chi-square dengan bantuan software SPSS. Dari hasil analisis data dapat disimpulkan bahwa kegiatan yang paling terpengaruh oleh tahap kegiatan pengerukan adalah aktivitas nelayan. Sebesar 33,6% responden menyatakan
tahap mobilisasi alat berat mengganggu ruang gerak nelayan di laut. Sedangkan 37,3% responden menyatakan tahap pengerukan (dredging) mengakibatkan penurunan hasil
tangkapan nelayan. Sementara itu, 30,8% responden mengeluhkan kerusakan pada alat tangkap yang diakibatkan oleh jaring yang terlanggar kapal pengangkut lumpur atau
alat dredging lainnya. Pada tahap pasca-pengerukan sebesar 3,4% responden menyatakan gangguan berupa pendangkalan kolam tambak dan penurunan kualitas air
laut, yang berdasarkan pemantauan kualitas air laut bulan November 2017 didapat parameter Kadmium (Cd)+ sebesar 0,002 mg/L dan Timah Hitam (Pb)+ sebesar 0,012 mg/L yang mana jumlah tersebut melebihi ambang batas baku mutu yang dianjurkan, yakni sebesar 0,001 mg/L untuk Kadmium (Cd)+ dan <0,008 mg/L untuk Timah Hitam (Pb)+. Namun, terlepas dari dampak negatif yang ditimbulkan, 64% responden menyatakan dukungan terhadap kegiatan pengerukan di PLTU Lontar.

Dredging activities carried out at the dock entrance, docks, and canal water intake Lontar power plant will have an impact on the decrease of sea water quality due to increased turbidity and suspended solids. A review of environmental and social aspects needs to be undertaken in the area of study which is the area or space used as a place of community life that is expected to be affected by dredging activities. The analysis conducted in this research is the analysis of the influence of dredging activities on the community and the environment by using quantitative methods with descriptive statistical analysis. Descriptive statistics used are descriptive percentage and cross tabulation (crosstab) and chi-square test with SPSS software.
From the results of data analysis can be concluded that the activities most affected by the dredging activity stage is the activity of fishermen. As much as 33.6% of
respondents said the stage of mobilization of heavy equipment disrupt the movement of fishermen at sea. While 37.3% of respondents said the dredging stage resulted in a decrease in the catch of fishermen. Meanwhile, 30.8% of respondents complained of damage to fishing gear caused by mud carrier vessels or other dredging equipment. In the post-dredging stage of 3.4% respondents stated that the disturbance of pond and the decrease of seawater quality, based on monitoring of seawater quality in November 2017, obtained parameters of Cadmium (Cd)+=
0.002 mg/L and (Pb)+=0.012 mg/L in which the amount exceeds the recommended quality standard threshold of 0.001 mg /L for Cadmium (Cd) + and <0.008 mg /L for (Pb)+. However, despite the negative impact, 64% of respondents expressed support for dredging activities at PLTU Lontar.
