Abstract
Instalasi Pengolahan Air Limbah (IPAL) PT. SIER merupakan pengelolaan air limbah industri dengan menggunakan activated sludge. Keberadaan IPAL untuk pengolahan limbah industri merupakan sumber pertambahan emisi pada kawasan tersebut. Kandungan COD dan BOD di dalam air limbah yang terdapat pada unit – unit IPAL dapat teroksidasi menjadi CO2 sehingga menghasilkan emisi. Penelitian ini menentukan data seri waktu konsentrasi CO2 selama 12 jam dan nilai kumulatif Net_CO2-Con serta menetapkan persamaan matematis proporsi vegetasi dalam mereduksi CO2 di kawasan IPAL PT. SIER.
Metode yang digunakan yaitu model box. Pengukuran konsentrasi CO2 dilakukan selama 12 jam setiap 2-3 jam pada 12 titik lokasi dengan 6 kali pengulangan pada hari Kamis. Metode perhitungan integrasi dan diferensiasi digunakan untuk menghitung nilai reduksi Net_CO2-Con. Analisis korelasi dan regresi dilakukan untuk mengetahui pengaruh proporsi vegetasi terhadap nilai reduksi Net_CO2-Con serta perumusan persamaan matematis vegetasi yang sesuai.
Nilai rata-rata konsentrasi seri waktu CO2 udara ambien di kawasan IPAL PT. SIER selama 12 jam yaitu 408,39 ppmV. Konsentrasi tersebut di atas ambang baku mutu CO2 udara ambien yang telah ditetapkan WHO (World Health Organization) tahun 2005 yaitu 310–330 ppm. Kawasan IPAL PT. SIER mereduksi CO2 sebesar 40,49 ppmV selama 12 jam. Hasil analisis korelasi dan regresi (α = 0,20) proporsi lahan terhadap nilai reduksi Net_CO2-Con menunjukkan bahwa proporsi vegetasi memiliki korelasi yang signifikan dan memiliki hubungan yang berbanding terbalik dengan nilai Net_CO2-Con. Proporsi unit IPAL dan proporsi jalan memiliki korelasi yang signifikan serta memiliki hubungan yang berbanding lurus dengan nilai Net_CO2-Con. Rumus persamaan empiris pengaruh proporsi vegetasi terhadap nilai reduksi Net_CO2-Con pada kawasan IPAL PT. SIER yaitu Net_CO2-Con = -30,71 – 31,94 %Proporsi Vegetasi.

PT. SIER wastewater treatment plant is industrial wastewater management using activated sludge. The existence of a wastewater treatment plant for industrial waste treatment is a source of increased emissions in the region. COD and BOD content in wastewater contained in IPAL units can be oxidized into CO2 resulting in emissions. This study determined the data series of CO2 concentration time for 12 hours and the cumulative value of Net_CO2-Con and established mathematical equations of vegetation proportion in reducing CO2 in the PT. SIER wastewater treatment plant.
The method used in this research is model box method. Measurement of CO2 concentration is performed for 12 hours every 2-3 hours at 12 location points with 6 repetitions on Thursday. Integration and differentiation calculation methods are used to calculate Net_CO2-Con reduction values. Correlation and regression analysis was conducted to determine the effect of vegetation proportions on Net_CO2-Con reduction values as well as the formulation of appropriate mathematical vegetation equations.
The average concentration of ambient air CO2 series in the IPAL PT region. SIER is 408.39 ppmV for 12 hours. The concentration is above the standard threshold of ambient air CO2 quality set by WHO (World Health Organization) in 2005 which is 310-330 ppm. PT. SIER wastewater treatment plant reduces CO2 for 12 hours is 40.49 ppmV. The results of correlation and regression analysis (α = 0.20) of land proportion to Net_CO2-Con reduction value showed that the proportion of vegetation had a significant correlation and had a relationship inversely proportional to the Net_CO2-Con value. The proportion of wastewater treatment plant and the proportion of roads has a significant correlation and has a relationship that is directly proportional to the value of Net_CO2-Con. Empirical equation formula of the effect of vegetation proportion on Net_CO2-Con reduction value in PT. SIER wastewater treatment plant area is Net_CO2-Con = -30,71 – 31,94 %Proportion Vegetation.
