Abstract

Industri manufaktur adalah industri yang dioperasikan untuk mengolah material menjadi barang jual yang memiliki nilai tinggi. Setiap industri juga memiliki tujuan, yaitu memperoleh keuntungan yang optimal dengan mempertahankan kualitas produk sesuai dengan standar yang ditentukan. PT King Plastic merupakan perusahaan manufaktur yang bergerak pada bidang produksi kemasan plastik dan jerry can. Proses pembuatan dilakukan dengan dua metode yaitu proses blow molding dan injection molding. Dalam mempertahankan kualitas produk, PT King Plastic melakukan analisis pada setiap produk yang dihasilkan. Namun, terdapat permasalahan terkait adanya perbandingan nilai dari banyaknya reject serta defect hasil produksi. Analisis dilakukan untuk mengetahui nilai reject serta macam-macam defect pada setiap mesin. Metode yang digunakan yaitu analisis menggunakan diagram pareto untuk melihat nilai presentase reject setiap mesin.  Dari kelima jenis mesin tersebut didapatkan bahwa defect yang dihasilkan hampir sama, akan tetapi jenis defect yang sering terjadi pada 5 jenis mesin tersebut yaitu: material asing (Q011) dan tebal/tipis/berat over/kurang (Q023).

Abstract

In this study, banana peel was used as a natural sunscreen compound because of its natural antioxidants, such as flavonoids, tannins, triterpenoids, and phenols. Extraction is carried out using Ultrasound-Assisted Extraction method with variations in ethanol solvent concentration and material to solvent ratio at 45oC for 45 minutes. The ethanol concentrations used are 96%, 70%, and 50% and the material to solvent ratio 1/10, 1/20, and 1/30. From the results of the study, the highest yield and SPF value were obtained at ethanol concentration of 50% and material to solvent ratio 1/30. The yield in this variation is 15.2646%, and the SPF value is 8.9874 with the maximum protection category. The highest Total Flavonoid Content (TFC) results was obtained at 70% ethanol concentration and the ratio of material to solvent 1/30, namely 1.6559 mg QE/g. From the variation with the best TFC value, the mass transfer coefficient is 0.0151 mL/µg QE.min.
