Industry in Indonesia is currently increasing both in terms of technology and diversity. However, industries ocated near the rivers tends to dispose of their wastewater into the river bodies which causes water pollution. PT. Wahana Kreasi Hasil Kencana (PT KHK) Tangerang is a metal coating industry that produces heavy metal wastewater. The wastewater has been processed in the wastewater treatment plant (WWTP) but has not met the discharge standard yet. The study aims to examine the process performance of wastewater treatment in an existing condition and in the addition of a biochemical oxidation process. The results showed that the existing a lower concentrations of Pb, TSS, Ni, Zn, Cu, BOD, and COD. While the addition of biochemical oxidation process by adding microorganisms (Microplus) revealed high effectivity in decreasing the concentration of the wastewater. The addition of microorganisms into WWTP proved that heavy metal concentration in the effluent was removed. The efficiency of the removal was 78%, 63%, 80%, 61%, 78%, 62% and for Ni, Zn, CN, Cu, Pb, and BOD respectively, but the COD removal was approximately COD 53%. Furthermore, statistical analysis showed that pH has also influenced the removal of BOD and TSS up to 95.3% and 75.6% respectively, while Ni, Zn, Cu, and Pb concentration was not affected by pH. Keywords: Chemical oxidation, Electroplating, Heavy metals, Wastewater ABSTRAK Industri di Indonesia saat ini telah berkembang pesat baik dalam hal teknologi maupun keanekaragamannya. Namun, ada kecenderungan industri yang berlokasi dekat aliran sungai membuang limbah cairnya ke badan sungai sehingga menyebabkan pencemaran. PT. Wahana Kreasi Hasil Kencana (PT WKHK) Tangerang merupakan salah satu industri pelapisan logam yang menghasilkan limbah cair logam berat. Limbah cair logam berat tersebut diolah pada instalasi pengolahan air limbah (IPAL) yang fluennya belum memenuhi baku mutu air limbah. Penelitian ini bertujuan untuk mengkaji proses kinerja pengolahan limbah cair pada IPAL PT WKHK Tangerang pada kondisi eksisting dan dengan penambahan proses pengolahannya. Penambahan proses pengolahan air limbah logam berat yang dilakukan adalah proses oksidasi biokimia. Hasil yang didapatkan dari hasil observasi ini adalah IPAL PT WKHK belum optimal dalam mereduksi konsentrasi Pb, TSS, Ni, Zn, Cu, BOD, dan COD sehingga belum memenuhi baku mutu. Sedangkan penambahan proses pengolahan biologi setelah unit intermediated basin dinilai cukup efektif dalam menurunkan konsentrasi limbah logam berat tersebut. Dibandingkan dengan kondisi eksisting, penambahan proses oksidasi biokimia dapat mereduksi lebih banyak konsentrasi logam berat pada efluen air limbah. Penambahan mikroorganisme pada pengolahan air limbah logam berat terbukti efektif dalam mereduksi konsentrasi dengan efisiensi 78%, 63%, 80%, 61%, 78%, 62% dan untuk parameter Ni, Zn, CN, Cu, Pb, dan BOD, sedangkan reduksi COD sebesar 53%. Analisis statistik menunjukkan adanya pengaruh pH terhadap penurunan konsentrasi BOD sebesar 95,3% dan TSS sebesar 75,6%. Sedangkan penurunan konsentrasi Ni, Zn, Cu dan Pb tidak dipengaruhi oleh pH.

Lakes, reservoirs, and rivers are among the most changing ecosystems on the earth’s surface. Chlorophyll-a as the main pigment in phytoplankton is often used to describe the water quality of lake and reservoirs and as an important element that indicates the tropical status of a waters. Spatial and temporal changes in algae blooms in a lake make it difficult to use in situ monitoring. The aim of the study is to predict the concentration of chlorophyll-a in Jatiluhur Reservoirs. The data used in this study were chlorophyll-a data from in situ measurements and satellite data Sentinel-2A. The method to obtain the value of the concentration of chlorophyll-a are an empirical and semi-analytical method. The empirical method is carried out by correlating in situ data with ratio of band 5 (red edge) and band 4 (red) (B5/B4). While the semi-analytical method is carried out by analyzing the Case 2 Regional Coast Colour (C2RCC) algorithm that integration in Sentinel Application Platform (SNAP) software. Correlation between in situ data and prediction of chlorophyll-a data has a strong relationship with the coefficient of determination R2=0.67 (in situ data with ratio prediction data) and R2=0.56 (in situ data with C2RCC prediction data). Based on this, remote sensing data on Sentinel-2A imagery with the application of several algorithms, can be used to support water quality monitoring activities in lakes and reservoirs, especially chlorophyll-a. Keywords: Chlorophyll-a, Sentinel-2A satellite imagery, Jatiluhur reservoirs, Empirical, Semi-analytical ABSTRAK Danau, waduk, dan sungai merupakan salah satu ekosistem yang paling banyak berubah di permukaan bumi. Klorofil-a sebagai pigmen utama fitoplankton sering digunakan untuk menggambarkan kualitas perairan danau dan waduk. Selain itu, klorofil-a merupakan unsur penting yang menandakan status tropik suatu perairan. Perubahan secara spasial dan temporal blooming alga pada suatu danau/waduk membuat sulit untuk melakukan monitoring secara in situ. Penelitian dilakukan untuk memprediksi nilai konsentrasi klorofil-a di Waduk Jatiluhur menggunakan data penginderaan jauh. Data yang digunakan dalam penelitian ini adalah data klorofil-a hasil pengukuran in situ dan data citra satelit Sentinel-2A. Metode yang digunakan untuk memprediksi nilai konsentrasi klorofil-a adalah metode empiris dan semi analisis. Metode empiris dilakukan dengan mengkorelasikan antara nilai klorofil-a in situ dengan nilai rasio band 5 (red edge) dan band 4 (red) (B5/B4). Sedangkan metode semi analisis dilakukan dengan analisis algoritma Case 2 Regional Coast Colour (C2RCC) yang terintegrasi pada perangkat lunak Sentinel Application Platform (SNAP). Hasil korelasi antara data in situ dan data prediksi klorofil-a diperoleh hubungan yang kuat dengan koefisien determinasi R2=0,67 (data in situ dengan data prediksi rasio) dan R2=0,56 (data in situ dengan data prediksi C2RCC). Berdasarkan hal tersebut, data penginderaan jauh citra Sentinel-2A dengan aplikasi beberapa algoritma, dapat digunakan untuk mendukung kegiatan monitoring kualitas perairan di danau dan waduk terutama klorofil-a.
