Abstract

Electrical energy plays an important role in human life and has become a major necessity for daily activities. One of the most commonly used sources of electrical energy is batteries, which are known as flexible energy sources because they can be utilized in various places and situations. However, batteries contain various hazardous chemicals, such as mercury, manganese, lead, nickel, lithium, and cadmium. Renewable energy and environmentally friendly storage technologies are urgently needed to reduce environmental impacts. This study aimed to determine the best ratio of carrageenan and PVA based on the performance of a carrageenan-PVA membrane as an organic anode in paper battery applications. The methods used included membrane preparation with varying ratios of carrageenan and PVA, membrane characteristics, air absorption, functional group analysis, tensile strength, proton conductivity, and electrical properties of paper batteries. The results of the study showed that the membrane with a ratio of 3:1 gave the best results, with the highest proton conductivity of 9.310-6 S/cm, air absorption of 93.91%, the highest electric current of 0.008±0.001 mA, the highest electric voltage of 0.24±0.02 V and the highest electric power of 0.0019±0.0004 mW. The FTIR spectrum of the carrageenan-PVA membrane showed no chemical reaction or the formation of new groups. Carrageenan-PVA has the potential to be an environmentally friendly, flexible battery material.

Abstract

Ikan asap merupakan salah satu produk olahan perikanan yang digemari karena rasanya khas dan aromanya yang sedap spesifik. Proses pengasapan menggunakan teknik konvensional memiliki umur simpan yang lebih pendek. Penjualan ikan asap tanpa pengemasan memungkinkan terpaparnya mikrob dan kapang kontaminan yang dapat memengaruhi mutunya. Pengemasan dengan metode modified atmosphere packaging (MAP) dan pengemasan plastik vakum merupakan upaya memperpanjang umur simpan dan mempertahankan mutu ikan asap. Tujuan penelitian ini, yaitu menentukan metode pengemasan dan lama waktu penyimpanan terbaik ikan tongkol (Euthynus affinis) asap yang disimpan pada suhu ruang. Metode eksperimen rancangan acak lengkap faktorial (RALF) dilakukan pada penelitian ini dengan variabel perlakuan metode pengemasan plastik nonvakum, vakum, dan MAP) serta lama waktu penyimpanan (hari ke-0, 1, 2, dan 3). Hasil uji mutu ikan asap yang diproduksi pada sentra pengasapan ikan bengkorok bakteri (Salmonella spp., S. aureus, E. coli) dan benzo[a]piren memenuhi standar SNI 2725:2013. Hasil analisis histamin pada setiap perlakuan selama penyimpanan sesuai standar SNI ikan asap, yaitu ≤100 mg/kg dengan nilai terendah pada metode pengemasan MAP, yaitu 52,32 mg/kg. Hasil analisis kimia dan mikrob pada pengemasan MAP dan plastik vakum hingga hari terakhir penyimpanan memenuhi standar SNI 2725:2013, kadar air < 60%, log total mikrob < 4,7 log CFU/g, dan log total kapang < 2 log CFU/g.
