Abstract

Pemanfaatan biomassa sebagai bahan baku energi alternatif saat ini menjadi fokus utama dalam upaya mengurangi ketergantungan terhadap bahan bakar fosil dan mengatasi masalah lingkungan. Dengan kandungan organik yang tinggi dan jumlah yang berlimpah, palm oil mill eflluent (POME) merupakan bahan baku potensial dalam produksi energi alternatif, sekaligus dapat menggantikan posisi tanaman pangan sebagai bahan baku bioenergi.  Produksi energi alternatif melalui limbah POME dapat dilakukan dengan biokonversi limbah secara anaerobik. Secara umum, produk bioenergi berupa bioetanol, biohidrogen, serta produk turunan berupa asam lemak volatil akan dihasilkan pada fase asidogenesis. Karakterisasi limbah POME menunjukkan nilai COD yang tinggi, yaitu mencapai 16.934 mg/L. Hasil identifikasi mikroorganisme menunjukkan POME didominasi oleh Lactobacillaceae, Acetobacteraceae, Prevotellaceae, dan Clostridiceae, yang merupakan kelompok bakteri yang berperan dalam degradasi senyawa organik menghasilkan produk berupa etanol, hidrogen, dan asam lemak volatil sehingga POME berpotensi sebagai bahan baku bagi produksi bioenergi.

Abstract

Personal Care Cosmetic Products (PCCPs) are used on the exterior of the body, such as the skin, nails, hair, lips, external genitalia, teeth, and oral membranes. Greywater from a bathing activity is a significant contributor to domestic wastewater quantity. The greywater contains residual substances from the rinsing process of body care products. Aim: This study will focus on the characteristic and the specific pollutant load of greywater generated from the usage of shower gel. Methodology and Results: The characterization and specific pollutant loads are conducted based on artificial greywater which is made from three brands of shower gel which is diluted in tap water. The greywater from body cleaning activities has a pH value in the range of 7.26-7.33; total phosphate in the range of 1.71-3.09 mg/L; the value of NTK total Kjedahl nitrogen in the range of 2.45-4.03 mg/L; total COD in the range of 380.97-506.16 mg/L; dissolved COD values in the range of 310.92-393.68 mg/L; TSS value in the range of 62-229.50 mg/L; and TDS values in the range of 283-376.67 mg/L. The specific pollutant load generated from shower gel usage in greywater are 0.012 g TP/person/day; 0.016 g TKN/person/day; 2.14 g Total COD/person/day; 1.59 g dissolved COD/person/day; 0.94 g/person/day for TSS; and 1.48 g/person/day for TDS. Conclusion, significance, and impact study: The Greywater from shower gel usage contains physical and chemical constituents that can promote environmental deterioration. The finding of this research will provide useful information for domestic wastewater management and system design, especially for urban areas in Indonesia.

Abstract

Indonesia is a country that has considerable coal reserves with coal resources of 149.01 billion tons. One of the problems of coal mining is turbidity. The turbidity is caused by the excavation of the open pit mine so that rainwater contact with the main wall. So that mud is formed, which can increase turbidity levels. The concentration of Total Suspended Solids (TSS) due to this phenomenon reaches 5,400 mg/L. Aim: This study aims to set aside TSS by electrocoagulation processing method using a batch system with eight pairs of iron electrodes arranged monopolarly. Methodology and Results: Comparisons using statistically independent t-tests showed that there was no significant difference between the iron and aluminium electrodes in the pH parameter. Conclusion, significance, and impact study:There were significant differences between iron and aluminum electrodes in the parameters of TDS and TSS. In the measured TDS and TSS parameters, the electrocoagulation process using iron electrodes has a higher value than aluminum electrodes. In the TSS removal, there is no significant difference between the two electrodes (iron and aluminium).
