Abstract

The increasing demand for meat has increased the number of livestock slaughtered. An increase in cuts means an increase in the waste generated. One of the wastewater treatment techniques is the aluminium (Al) plate electrocoagulation method. Electrocoagulation is a coagulation process or coagulation and deposition of fine particles in wastewater by utilizing electrical energy through an electrolysis process so that it can degrade pollutants or contaminants in RPH liquid waste. This research was conducted to determine the effect of variations in current density and contact time and their effectiveness in reducing levels of COD and TSS, as well as increasing DO and optimum pH changes in abattoir waste. The current density variations used are 40, 45 and 50 A/m2 with 30, 60, 90, 120, 150 and 180 minutes of contact times. The effectiveness of electrocoagulation on the decrease in the highest TSS value was 96.04%, and COD was 76.81%, with a contact time of 180 minutes and a current density of 50 A/m2. The pH value increased at 50 A/m2 current density with a contact time of 180 minutes, an increase from 5.9 to 8.1, and the DO value increased at a current density of 50 A/m2 with a contact time of 180 minutes, an increase from 1.2 to 4,3 mg/L.

Abstract

Penelitian ini bertujuan untuk menganalisis indikator produk skincare yang dapat dikategorikan sebagai overclaim serta bentuk tanggung jawab produsen terhadap kerugian konsumen akibat praktik tersebut. Overclaim dalam konteks ini merujuk pada klaim berlebihan atau menyesatkan yang tidak sesuai dengan kandungan sebenarnya maupun tidak didukung oleh bukti ilmiah yang valid. Penelitian ini menggunakan pendekatan hukum normatif dengan menelaah peraturan perundang-undangan seperti Undang-Undang Nomor 8 Tahun 1999 tentang Perlindungan Konsumen, Kitab Undang-Undang Hukum Perdata, serta regulasi teknis dari Badan Pengawas Obat dan Makanan (BPOM). Hasil penelitian menunjukkan bahwa indikator suatu produk dikategorikan overclaim antara lain apabila terdapat ketidaksesuaian antara klaim dan komposisi produk, penggunaan bahasa yang menyesatkan, serta tidak terpenuhinya ketentuan hukum mengenai periklanan dan informasi produk. Praktik overclaim ini terbukti merugikan konsumen secara materiil dan immateriil. Berdasarkan hasil analisis, produsen memiliki tanggung jawab hukum, etika, dan sosial terhadap kerugian yang ditimbulkan akibat overclaim. Tanggung jawab tersebut mencakup kewajiban memberikan informasi yang benar, jelas, dan jujur serta menyediakan produk yang aman dan sesuai standar. Penelitian ini menegaskan pentingnya penegakan regulasi serta kesadaran produsen dalam mematuhi ketentuan hukum guna melindungi konsumen dari praktik promosi yang menyesatkan.
