Plastik merupakan bahan yang banyak digunakan dalam kehidupan sehari-hari, tetapi mencemari lingkungan karena plastik tidak dapat diuraikan oleh lingkungan. Penelitian mengenai bioplastik diperlukan untuk bahan alternatif plastik yang mudah terurai. Karagenan dan amilum merupakan polisakarida yang berpotensi sebagai bahan pembuatan bioplastik. Tujuan dari penelitian ini untuk menentukan perbedaan karakteristik (ketebalan, kuat tarik dan elongasi) bioplastik berbahan dasar karagenan dan gliserol terhadap pertambahan konsentrasi amilum. Metode penelitian yang digunakan yaitu Eksperimental Laboratorium. Karagenan diperoleh dari ektraksi K. alvarezii yang berasal dari perairan Jepara, Jawa Tengah. Bioplastik dibuat dengan gelatinasi amilum (1; 2; 3; dan 4 g) dalam 50 ml akuades pada suhu 90ºC selama 15 menit dalam erlenmeyer menggunakan Hot Plate Stirrer. Gliserol 20% ditambahkan dan dihomogenkan selama 5 menit. Suhu diturunkan hingga 70ºC, selanjutnya karagenan 1 g dan akuades ditambahkan hingga volume 150 ml dihomogenkan selama 45 menit. Bioplastik dicetak dan dikeringkan di oven selama 18 jam pada suhu 50ºC. Hasil penelitian menunjukkan bahwa karakteristik bioplastik κ-karagenan dengan penambahan amilum yaitu memiliki kuat tarik 6,42-11,47 MPa, nilai elongasi 7,03-21,88% dan ketebalan 0,13-0,25 mm. Elongasi konsentrasi amilum 1 g telah memenuhi standar SNI. Parameter yang sesuai dengan standar Japanese Industrial Standard yaitu parameter kuat tarik dan ketebalan. Plastic is a material that is widely used in everyday life, but it pollutes the environment because plastic cannot be decomposed by the environment. Research on bioplastics needs to get alternative materials for plastics that are easily biodegradable. Carrageenan and starch are polysaccharides that have the potential as materials for making bioplastics. This study aimed to determine differences in characteristics (thickness, tensile strength, and elongation) of bioplastics based on carrageenan and glycerol because of increased starch concentration. The research method used is Experimental Laboratory. Carrageenan from the extraction of K. alvarezii from the waters of Jepara, Central Java. Bioplastics were prepared by gelatinization starch (1; 2; 3; and 4 g) in 50 ml of distilled water at 90ºC for 15 minutes in an Erlenmeyer using a Hot Plate Stirrer. Glycerol 20% was added and homogenized for 5 minutes. Lower the temperature to 70ºC, then add 1 g of carrageenan and distilled water until the volume is 150 ml, after that homogenize it for 45 minutes. The bioplastics were molded and dried in the oven for 18 hours at 50ºC. The results showed that the characteristics of κ-carrageenan bioplastic with the addition of starch had a tensile strength of 6.42-11.47 MPa, an elongation value of 7.03-21.88% and a thickness of 0.13-0.25 mm. The elongation of starch concentration of 1 g is in accordance with the SNI standard. Parameters that comply with the Japanese Industrial Standard are the tensile strength and thickness parameters.

“…This is because studies have shown that seaweed-based bioplastics have good protective qualities (Lomartire et al, 2022). There are a few types of seaweed-based bioplastics that differ in terms of their source of biomass, like using whole seaweed (Hanry & Surugau, 2020;Moey et al, 2018), agar (Hii et al, 2016), alginate (Castro-Yobal et al, 2021;Yupa et al, 2021), and carrageenan (Farhan & Hani, 2017;Nasution et al, 2019). However, the properties of seaweed-based bioplastics depend on a few factors, starting from the source of biomass until the process of developing bioplastics (Lomartire et al, 2022).…”

Plastic pollution has become one of the most concerning problems globally due to excessive use of one-time use plastics. However, bioplastics could be the answer to help combat this problem as they are readily biodegradable. Development of bioplastics was done by mixing seaweed biomass into distilled water at specific ratio, using glycerol as plasticizer. Bioplastics were developed at the ratio of 100:0, 75:25, 50:50, 25:75, and 0:100 K. alvarezii to commercial sodium alginate ratio. Characterization was done based on their appearance, mechanical, thermal and permeability properties, and biodegradability. Resulted data for their appearance showed that when more K. alvarezii was in the mixture there were more colour differences in comparison to white background and the same trend for the opacity due to the natural colour of whole K. alvarezii. As for their mechanical properties, tensile strength of the bioplastics decreased from 100:0 ratio to 0:100 ratio at 7.91 ± 0.45 MPa (100:0), 6.78 ± 0.31 MPa (75:25), 5.20 ± 0.37 MPa (50:50), 4.13 ± 0.17 MPa (25:75) and 3.76 ± 0.14 MPa (0:100), respectively. Same goes for their elastic modulus at 20.93 ± 0.61 MPa (100:0), 16.47 ± 0.99 MPa (75:25), 11.42 ± 0.53 MPa (50:50), 8.78 ± 0.45 MPa (25:75) and 6.65 ± 0.32 MPa (0:100), respectively. This shows that the addition of alginate enhances the elasticity but decreases tensile strength. As a conclusion, developed seaweed-based bioplastics resulted different properties at different mixture ratio show potential to be incorporated into the market as they are a greener option to fight single-use plastic wrappings such as saran wrap, beverages and food additive packets.

The natural resources of agricultural products have the potential to be raw material for making biodegradable plastic, one of which is starch from kluwih seeds (Artocarpus camansi). This study examines the potential of kluwih seed starch as a basic material for making biodegradable plastic. This research method is experimental, the raw material for making biodegradable plastic is the kluwih seed starch originating from Aceh Besar Regency, Aceh Province. Other additives used are chitosan as reinforcement and glycerol as plasticizers. The analysis is carried out, namely mechanical properties, morphology, thermal, functional groups, water absorption and degradation analysis. The results of the analysis of this study show that the kluwih seed starch functions as a basic material for making biodegradable plastic. As chitosan concentration increases, the resulting tensile strength increases with results obtained around 119.17-166.67 kgf/mm2, while the percentage of elongation is lower the results obtained are 6.82-11.15%. The morphological analysis shows the biodegrable plastic produced has a compact and homogeneous structure. The thermal analysis shows a good thermal stability to ranging from 180 to 370 oC. The results of the biodegradable plastic FTIR show wave numbers 1662.64–1049 cm-1. Water absorption analysis is obtained around 7.658-12.068%, a decrease in water absorption is influenced by the addition of chitosan concentration. Biodegradable paltic planted in the soil containing EM4 degraded for 3 days.
