Abstract

Air limbah yang dihasilkan dari industri petrokimia berupa pupuk tersebut masih mengandung banyak kadar ammonia sehingga perlu dihilangkan terlebih dahulu sebelum di buang ke lingkungan. Baku mutu kadar ammonia dalam air limbah adalah 300 ppm. Ammonia Stripper pada IPAL berperan untuk melucuti ammonia dalam air limbah perlu di evaluasi untuk mengetahui kelayakan alat tersebut dan mengetahui pengaruh flowrate terhadap kinerja stripper. Hasil evaluasi menggunakan software ASPEN HYSYS menunjukkan bahwa kadar ammonia yang berhasil dilucuti dari air limbah sedikit lebih tinggi untuk data desain sekitar 296 ppm dibandingkan dengan data desain yaitu 2,7 ppm. Bila ditinjau dari kadar pH air limbah yang telah di proses ammonia stripper menunjukkan masih diatas baku mutu (7-8,5) yaitu 8,9-9,0. Efisiensi alat ammonia stripper berbanding lurus dengan flowrate steam per flowrate air limbah, Perbandingan antara flowrate steam dengan air limbah agar tetap berada di standar baku mutu adalah 0,385 m3 /ton. Data aktual yang lebih tinggi dibandingkan data desain menunjukkan bahwa Ammonia Stripper pada IPAL perlu dilakukan perawatan atau perbaikan agar kinerjanya data lebih mendekati data desain, namun alat tersebut masih dapat dikatakan layak untuk digunakan karena masih berada di dalam baku mutu, yaitu 296 ppm.

Abstract

Acid Mine Drainage (AMD) generated by coal mining is commonly regarded as an environmental liability, yet it may also serve as a secondary source of Rare Earth Elements (REEs). This study evaluated the distribution, classification, and recovery potential of REEs in AMD water and sedimentation pond sludge from a coal mining area in South Sumatera, Indonesia. Four AMD water samples were collected from different mine pits, while two sludge samples were obtained from the inlet and outlet of a sedimentation pond. REEs concentrations were determined using Inductively Coupled Plasma–Mass Spectrometry, and recovery potential was assessed using the Outlook Coefficient and the relative proportion of critical REEs. The results showed that REEs concentrations in AMD water were low, ranging from 0.0005 to 0.449 ppm, with PIT 1 exhibiting the highest concentration under strongly acidic conditions. However, sludge samples exhibited considerable REEs enrichment with total concentrations of 178.13 ppm and 59.09 ppm at the inlet and outlet of the sedimentation pond, respectively. The preliminary outlook analysis showed low potential for direct recovery of REEs from AMD water, but sedimentation pond sludge, especially at the outlet, showed a promising outlook due to its combined high total REEs concentration and high critical content. This study showed that REEs can be recovered and concentrated in solid phases of AMD treatment systems. In addition, the sludge was a more viable and environmentally friendly secondary source.

Abstract

Consumption of fuel energy continues to increase every year. Still, the fuel used today is almost entirely derived from fossil materials that are toxic to the environment and not renewable, so they need renewability to be guaranteed. One solution to this problem is ethyl ester based on catfish (Pangasius Hypothalamus) tallow waste. The catfish fish tallow is extracted first and then in a liquid phase and then reacted with the help of a KOH catalyst (1%; 1.5%; 2%) by electrolysis method using copper electrodes with a transesterification reaction. The research was conducted on the ratio of raw materials to ethanol of 1:5, 1:6, and 1:7 with a power supply voltage of 20V. It can be seen from the research results that the mole ratio of raw material and ethanol at 1:6 produces ethyl esters with a tendency to be of better quality. The best ethyl ester yield was obtained at a ratio of 1:6 raw material and 1.5% catalyst amount, and the resulting yield was 92.4058%.
