Abstract

Tanaman kelapa memiliki banyak manfaat mulai dari akar, pohon hingga buah. Hingga saat ini pohon kelapa banyak dimanfaatkan namun masih belum optimal, khususnya limbah padat kelapa. Limbah padat kelapa dapat diubah menjadi briket bio arang yang dapat dimanfaatkan sebagai bahan bakar alternatif yang ramah lingkungan. Briket adalah proses percetakan bahan menjadi bentuk kotak, bulat, silinder atau bentuk lain yang memungkinkan dalam bentuk padat dengan memberi tekanan dari luar. Tujuan penelitian ini untuk memanfaatkan limbah sampah organic sebagai bahan baku briket arang. Proses pengarangan dilakukan dengan drum kiln yang di modifikasi. Arang yang diperoleh kemudian ditumbuk dan kemudian dijadikan bahan baku briket arang. Kegiatan pengabdian masyarakat ini bersama ibu-ibu PKK RK 02 di Desa Rawang Kao Barat, Lubuk Dalam, Kabupaten Siak. Kegiatan ini diharapkan dapat melatih masyarakat agar dapat memanfaatkan limbah padat kelapa menjadi briket sederhana yang dapat dimanfaatkan menjadi sumber bahan bakar pengganti minyak tanah.

Abstract

Young leachate from the inlet zone of Muara Fajar Landfill is characterized by high acidity (pH 5.5) and pollutant load, posing risks of heavy metal mobilization into groundwater. This study evaluates the performance of alkali-activated duck eggshell biosorbent as a neutralizing and clarifying agent for acidogenic leachate. A batch system was employed with varying contact times (0–120 mins), 2% (w/v) adsorbent dosage, and 175 rpm agitation. Results showed the biosorbent effectively increased leachate pH from 5.5 to 6.6, complying with MoEF Regulation No. 59/2016 standards. Turbidity decreased by 37% (72.4 to 45.6 NTU) at the optimum time of 60 minutes. Kinetic analysis fitted the Pseudo-Second Order model (R2= 0.9557) with a maximum adsorption capacity (qe) of 1.49 NTU.L/g and rate constant (k2) of 0.041 g/NTU.min, indicating dominant chemisorption mechanisms. Duck eggshell waste shows potential as an economical, eco-friendly pre-treatment for acidic leachate.

Abstract

This study evaluates the potential of activated carbon derived from oil palm mesocarp fibers (OPMF) using 0.5 M NaOH activation as a sustainable solution for the advanced treatment (polishing) of POME. Through a pyrolysis process at 250°C, the carbon produced a 16.5% yield and 4.44% moisture content, meeting the SNI 06-3730-1995 standards. The results indicate that an adsorbent dosage of 3 grams per 200 mL of sample significantly reduced COD levels by 50.03% (to 14,261 mg/L), although the final value has not yet met the quality standards of Permen LHK No. 5 of 2014. However, this activated carbon proved highly effective in improving acidity levels, increasing the effluent's pH from 5.37 to 7.31, thereby successfully.
