Abstract

Penggunaan sampah plastik semakin meningkat seiring berkembangnya teknologi oleh karena itu, perlu adanya alternatif proses daur ulang. Salah satunya adalah mengonversi sampah plastik menjadi minyak. Tujuan dari penelitian ini adalah untuk memanfaatkan sampah plastik LDPE (Low Density Polyethylene) dan PP (polipropilena) dengan cara pirolisis. Pengolahan sampah plastik menjadi minyak dilakukan selama 180 menit dengan jumlah sampah plastik yang diperlukan dalam satu kali percobaan sebanyak 6000 gram dengan 3 kali pengulangan. Penelitian dilakukan di TPA Wonosari Kota Singkawang dengan parameter yang diuji densitas, viskositas, dan warna. Hasil pirolisis diuji konsistensinya menggunakan uji statiska non parametrik (Uji Mann Whitney). Berdasarkan hasil penelitian, nilai parameter fisik viskositas dan densitas minyak hasil pirolisis LDPE   rata-rata 0,302 cP, LDPE katalis 0,114 cP serta densitasnya 767 kg/m3 dan 737 kg/m3. Sedangkan, nilai PP viskositas rata-rata 2,812 cP, PP katalis 0,248 cP serta densitasnya 774 kg/m3 dan 735 kg/m3. Berdasarkan hasil analisis kualitas dan kuantitas serta uji konsistensi dengan statiska bahwa nilai densitas sampel mendekati bensin, sedamgkan nilai viskositas tergolong dalam klasifikasi minyak tanah.

Abstract

Clean water is essential for human life; however, its distribution in Kubu Raya Regency remains limited, prompting residents to rely on dug wells as their primary water source. In the Hosana Fhileo residential area, groundwater quality exceeds permissible limits, with iron (Fe) concentration at 14.41 mg/L and turbidity at 288 NTU, surpassing the standards set by the Indonesian Ministry of Health Regulation No. 2 of 2023. Concurrently, the abundance of eggshell waste offers potential for its use as a natural coagulant due to its calcium carbonate (CaCO₃) content. This study aims to evaluate the effectiveness of eggshell powder as a coagulant in reducing iron concentration and turbidity in groundwater, and to compare it with the chemical coagulant Poly Aluminium Chloride (PAC). Laboratory-scale jar tests were conducted in two stages: the first used eggshell powder at 30, 50, and 70 g/L, while the second used PAC at 60, 70, and 80 g/L. Results showed that a 70 g/L dose of eggshell powder reduced iron concentration by 34.52% to 9.44 mg/L (p = 0.003 < 0.05) and turbidity by 90.61% to 27.05 NTU (p = 0.002 < 0.05). In contrast, a 60 g/L PAC dose increased iron levels to 16.32 mg/L (p = 0.002 < 0.05), but reduced turbidity by 84.57% to 44.43 NTU (p = 0.001 < 0.05). These findings indicate that eggshell powder is a promising eco- friendly coagulant. However, its Fe removal efficiency may be improved through process optimization, such as pH adjustment to enhance coagulation performance.
