The utilization of pumice as an adsorbent has been tested in adsorption column applications in removing chromium (Cr) from groundwater. The pumice was taken from the banks of the Pasak River, Pariaman, West Sumatra. The column used is made of glass with 130 cm in height and 2,6 cm in diameter. The experiment was carried out by varying the bed height (65, 75, and 85 cm) and the influent flow rate (2, 3, and 4 gpm/ft2), while the influent concentration used was according to the groundwater sample conditions. The concentration of Cr was analyzed using inductively coupled plasma emission (ICPE). The performance of the adsorption column can be evaluated from the breakthrough curve, which is a plot between the Ct/C0 ratio and the sampling time. The experimental results showed that the optimum condition with the highest removal efficiency of 65.15% and an adsorption capacity of 0.0031 mg/g were obtained at a bed height of 85 cm and an influent flow rate of 2 gpm/ft2. Based on the experimental results, it was concluded that Cr removal efficiency increased as the influent flow rate decreased and as the bed height of adsorbent increased. The adsorption column with Sungai Pasak Pariaman pumice as an adsorbent has potential to be applied in removing Cr metal from groundwater.

Fly ash and bottom ash (FABA) in Sawahlunto City are backfilling materials for former mining areas. The FABA dumping is estimated to hurt groundwater. This study aims to analyze the concentration of Pb metal in groundwater and its distribution using response surface methodology. This study is a quantitative experimental field research using Response Surface Methodology (RSM). The research subjects involved were groundwater samples from four different points around the fly ash and bottom ash (FABA) dumping location in Sawahlunto City. The data collection method was carried out by taking groundwater samples three times consecutively with a three-week interval, following the procedures of SNI 6989.58: 2008 and SNI 6989-84: 2019. Data analysis methods included ANOVA and RSM tests in the SAS platform. The research findings showed that the groundwater at the study location did not meet drinking water quality with a Pb concentration of 0.144 mg/L exceeding the quality standard (0.01 mg/L). The accumulation of FABA in former mining areas pollutes groundwater with Pb parameters. The distribution pattern of Pb decreases with increasing distance and increases with increasing time. Therefore, the government needs to re-evaluate the implementation of FABA utilization as a filling material for former mining areas. The implications of this study indicate the need to re-evaluate the practice of FABA disposal in mine pits, as improper waste disposal will negatively impact groundwater quality.

Batu Ampar Port is the largest loading and unloading port of the three existing loading and unloading port facilities in Batam and the largest port for manufactured goods used by companies to supply the industrial sector in Batam. In addition to having a positive impact, the Batu Ampar port also has a negative impact in the form of a decrease in environmental quality, especially the noise level generated by activities in the Batu Ampar Port area. In this study the noise sampling process used the Svantek tool, sampling was carried out for 24 hours with a time limit of 24 intervals, then sampling was carried out for 10 minutes at each time interval. The research results obtained were that from all sampling points the highest noise was in the East Pier area of 70 – 78.5 dB(A) at 08:00 – 23:00 WIB. While the area with the lowest noise level is in the BPJS flat area of 54.7 – 73.5 dB(A) at 06:00 – 05:00 WIB. It can be concluded that many of the noise values obtained exceed the quality standards in accordance with Kepmen LH No. 48 of 1996. This was due to several factors, namely loading and uploading of very dense containers which resulted in more and more work activities. Noise elimination measures in the Batu Ampar port area are important to do considering the results of noise measurements still exceed the quality standards, Barriers are one of the technologies that can be applied to reduce noise in the Batu Ampar port, Batam, both natural and artificial barriers, so the Batu Ampar port noise problem can be solved

Batu apung dikenal sebagai material low-cost yang memiliki struktur berpori sehingga berpotensi sebagai adsorben untuk menyisihkan senyawa polutan dalam air, seperti amonium yang hadir sebagai dampak aktivitas industri, pertanian maupun domestik. Keberadaan batu apung yang melimpah terdapat di daerah Sungai Pasak dan hingga saat ini belum dimanfaatkan. Kemungkinan adanya regenerasi dari adsorben yang telah digunakan merupakan keuntungan proses adsorpsi sebagai salah satu teknologi ramah lingkungan. Regenerasi dapat dilakukan melalui proses desorpsi sehingga reuse dapat diterapkan terhadap adsorben dan recovery terhadap senyawa yang disisihkan. Tujuan penelitian ini adalah untuk mengetahui agen desorpsi terbaik yang berguna untuk regenerasi, yaitu memperpanjang masa pakai batu apung khususnya pada proses penyisihan amonium. Regenerasi terdiri dari percobaan adsorpsi dan desorpsi dengan metode batch sebanyak 2 kali reuse menggunakan kondisi optimum yang diperoleh, terdiri dari pH, waktu kontak, ukuran serta dosis batu apung yang diaplikasikan pada larutan artifisial dan sampel. Proses desorpsi menggunakan agen desorpsi asam (HCl), netral (akuades) dan basa (NaOH). Percobaan pada larutan artifisial amonium 4 mg/l menghasilkan HCl sebagai agen desorpsi terbaik dengan kapasitas adsorpsi tertinggi, yaitu reuse I 6,335 mg/g serta reuse II 6,018 mg/g dengan efisiensi penyisihan rata-rata 46,324%. Agen HCl juga memberikan % desorpsi tertinggi pada proses desorpsi I dan II sebesar 89,734% dan 88,048%. Percobaan juga dilakukan terhadap sampel air tanah dekat area pertanian dengan % desorpsi pada desorpsi I dan II yaitu 87,875% dan 86,892%, dengan kapasitas adsorpsi saat reuse I dan II adalah 1,889 mg/g dan 1,845 mg/g. Hasil penelitian menunjukkan agen terbaik untuk regenerasi batu apung yaitu asam (HCl) dengan kemampuan hingga 2 kali reuse dengan nilai efisiensi penyisihan dan kapasitas adsorpsi hampir sama dengan nilai adsorpsi awal, sehingga memungkinkan untuk dilakukan reuse selanjutnya. Potensi batu apung Sungai Pasak ini dapat dimanfaatkan dalam pengolahan air tanah maupun air limbah dengan kandungan amonium yang rendah.
