Abstract

The relatively high silica content in bagasse ash can be used as raw material for making zeolite. Zeolite can be used as a heavy metal adsorbent in industrial wastewater treatment. This study aims to synthesize zeolite from bagasse ash and to apply zeolite as an adsorbent of Cu(II) in a continuous system reactor. The effects of contact time, zeolite size, and concentration of Cu(II) solution on the removal efficiency of metals have been studied in this research. The synthesis of zeolite was carried out using the hydrothermal method at 100°C for 7 hours. The synthesized zeolite was characterized using SEM-EDX, XRD, FTIR, and BET The adsorption process was carried out using a continuous reactor with a flow rate of 0.4 L/min and flowed for 60 minutes with sampling at 15-minute intervals. The zeolite size used was 100 and 200 mesh. The results of SEM-EDX analysis showed that Zeolite has an irregular morphology and contains Si at 35.15%. The XRD results show that the zeolite crystallinity is relatively low. The specific surface area of zeolite at size 100 mesh and 200 mesh were 439.48 m2 /g and 697.76 m2/g respectively. The best Cu(II) waste adsorption test results were obtained under zeolite conditions with a particle size of 200 mesh, the concentration of Cu(II) wastewater of 25 mg/L, and an operational time of 60 minutes with a removal efficiency of Cu(II) of 41.57%

Abstract

Pembangkit Listrik Tenaga Uap (PLTU) Kabupaten Probolinggo sebagai industri pembangkit listrik tenaga uap berbahan bakar batubara menghasilkan beberapa parameter emisi dari proses industrinya, salah satunya Sulfur Dioksida (SO2). Emisi SO2 ini dikeluarkan melalui cerobong dimana nantinya akan menyebar ke kawasan sekitar plant. Emisi SO2 ini dapat berbahaya bagi kesehatan masyarakat dan lingkungan sekitar apabila Flue-Gas Desulfurization (FGD) sebagai instalasi pengendali emisi SO2 sedang bermasalah dan membutuhkan corrective maintenance. Oleh karena itu perlu dilakukan penelitian terkait analisis dispersi emisi SO2 agar dapat mengestimasikan dampak dari emisi tersebut terhadap lingkungan sekitar. Tujuan penelitian ini yaitu menganalisis dispersi emisi SO2 dari cerobong PLTU Kabupaten Probolinggo Unit 9 pada musim kemarau. Penelitian dilakukan dengan menggunakan data emisi pada periode pemantauan Bulan Juli – September 2019 dan data meteorologi pada periode pemantauan Januari 2018 – Mei 2020. Pada penelitian ini, Gaussian Dispersion Model dipilih untuk memodelkan dispersi emisi SO2. Software Surfer dan Google Earth digunakan untuk penggambaran pola dispersi emisi SO2. Hasil penelitian menunjukkan bahwa emisi SO2 terdispersi ke arah selatan dengan stabilitas atmosfer kelas B pada musim kemarau. Konsentrasi tertinggi emisi SO2 berdasarkan hasil model sebesar 107,74 μg/m3 dengan koordinat 7°43’43.452” LS; 113°34’17.766” BT dan memiliki jarak sebesar 1986,87 meter dari cerobong. Setelah sampai di titik maksimum, konsentrasi emisi terus menurun seiring dengan bertambahnya jarak dari cerobong.

Abstract

Masalah akibat kepadatan penduduk adalah meningkatnya sampah yang mencakup keseluruhan wilayah, baik perkotaan maupun pedesaan. Sampah di wilayah pedesaan didominasi oleh sampah organik pasar dan limbah peternakan. Tidak berjalannya sistem pengolahan dan pendistribusian sampah yang baik, menyebabkan penumpukan sampah seperti pada wilayah Dusun Gedangklutuk, Desa Kedungboto, Kabupaten Pasuruan. Kegiatan ini bertujuan untuk memanfaatkan sampah organik dan limbah peternakan sebagai Energi Baru Terbarukan (EBT) ramah lingkungan dengan metode biodigester. Biodigester mampu mengubah sampah organik pasar menjadi biogas yang memiliki kandungan CH4 sekitar 50-75%, CO2 sekitar 25-50%, dan sisanya adalah gas lain yang persentasenya sangat kecil. Gas berasal dari penguraian bahan organik oleh bakteri anaerob dengan suhu optimum sekitar 30-35°C dan pH sekitar 6-8. Biodigester menghasilkan 847,8 liter gas yang tertampung.
