Abstract

Pepaya dimanfaatkan pula daunnya sebagai sayuran dan pelunak daging. Daun pepaya muda dimakan sebagai lalap (setelah dilayukan dengan air panas) atau dijadikan pembungkus buntil. Bunga pepaya yang diurap menjadi sayuran yang biasa dimakan. Getah pepaya (dapat ditemukan di batang, daun, dan buah) mengandung enzim papain, semacam protease, yang dapat melunakkan daging dan mengubah konformasi protein lainnya. Tujuan PKM adalah (1). Memanfaatkan buah pepaya dengan menggunakan teknologi esterifikasi. (2). Melakukan pembuatan sabun alami dengan penambahan bahan organic untuk menghasilkan senyawa kimia bioaktif Mmenjalin kemitraan kelompok petani pepaya dan pihak terkait (masyarakat dan Desa) agar memanfaatkan buah papaya dan biji papaya untuk digunakan untuk bahan pembuatan sabun. Rencana PKM ini akan diilaksanakan Kecamatan Anggeraja di Kabupaten Enrekang, Jenis luaran yang dihasilkan sesuai rencana kegiatan PKM ini adalah produk berupa teknologi tepat guna berupa esterifikasi di modifikasi untuk menghasilkan sabun alami , Pelatihan pembuatan sabun organic dari limbah papaya mampu meningkatkan kesejakteraan petani di kelurahan tanete dan mampu mengetahui cara mengolah limbah papaya untu produk sabun organic, dan produk sabun tersebut bisa dilaukan dari rumah masyarakat petani tersebut.

Abstract

A new modification of natural coagulant and flocculant from papaya seeds Carica papaya L. and aloe vera gel has been developed in this study to remove Remazol Yellow dye. The research parameters studied included the initial concentration of the test solution, pH, and stirring speed during the coagulation process. The initial concentration of the test solution varied from 10 to 50 mg/L, the pH ranged from 1 to 6, and the stirring speed was 650 to 1050 rpm during the coagulation phase. The coagulation and flocculation results were characterized using an FTIR spectrophotometer. The results showed that the optimum conditions were an initial concentration of 30 mg/L at pH 2 and a stirring speed of 950 rpm, resulting in the highest removal effectiveness of 97.55%. The results of FTIR spectrophotometry characterization showed that the sulfonate group -SO₃⁻ in Remazol Yellow had been removed, indicating that the protonated groups -NH₃⁺ and -COOH₂⁺ in papaya seeds and the anionic groups of the dye had electrostatic interactions. This study shows that the modification of papaya seeds and aloe vera gel as natural coagulants and flocculants shows sustainable potential for azo dye-based textile wastewater treatment.

Abstract

Textile dye effluents are hazardous because many residual dyes are persistent, toxic, and potentially carcinogenic. This study assessed an environmentally friendly coagulation flocculation route to remove Remazol Yellow, an azo dye used in the batik industry in South Sulawesi, by substituting synthetic reagents with papaya (Carica papaya) seeds as a coagulant and Aloe vera gel as a flocculant. FTIR confirmed hydroxyl, carboxyl, and amine groups in papaya seeds, while Aloe vera gel was dominated by polysaccharide and carboxylate features. Jar tests were performed at room temperature using an initial dye concentration of 30 mg L−1. Coagulation was conducted for 5 min at 950 rpm, followed by flocculation for 30 min at 125 rpm and sedimentation for 30 min. Residual dye was measured by UV Vis spectrophotometry at 417 nm. Operational variables were optimized, including coagulant particle size (30 to 100 mesh), papaya seed dose (10 to 50 mg L−1), and Aloe vera gel dose (10 to 60 g L−1). The optimum particle size was 70 mesh, giving 60.4 percent removal. The optimum papaya seed dose was 20 mg L−1 with 83.5 percent removal, and the optimum Aloe vera gel dose was 50 g L−1, achieving 97.4 percent removal. These results demonstrate the potential of papaya seeds and Aloe vera gel as effective and sustainable materials for batik dye wastewater treatment.
