Judul: Characteristics  Testing of Bioplastik Based Packaging for Fresh Products
Abstrak: Produk hortikultura merupakan produk yang mudah mengalami kerusakan yang biasanya dikarenakan oleh penanganan pascapanen yang tidak sesuai terutama pada pengemasan. Kemasan plastik banyak digunakan sebagai bahan kemasan yang popular namun tidak ramah lingkungan. Maka dari itu penggunaannya dapat digantikan dengan bioplastik. Penelitian ini bertujuan untuk mengkaji karakteristik dari kemasan bioplastik berbahan dasar pati dan High Density Polyethylene (HDPE) dengan variasi kondisi penyimpanan lalu membandingkan nilai perubahan mutu produk segar terhadap pengaplikasian kemasan selama penyimpanan. Pengujian karakteristik dilakukan dengan memperhatikan parameter Water Vapor Transmission Rate (WVTR) serta sifat mekanik dari kedua jenis kemasan selama penyimpanan 8 jam pada variasi suhu 16 ˚C, 25 ˚C, dan 30 ˚C, dan variasi RH 18%, 51%, 79%, dan 90%. Pengujian perubahan mutu selama pengaplikasian dilakukan dengan menggunakan pisang cavendish dengan memperhatikan parameter laju respirasi, susut bobot, dan perubahan warna serta sifat mekanik dari kemasan setelah dilakukan penyimpanan selama 10 hari dengan variasi suhu 16 ˚C dan 25 ˚C. Pengamatan pada produk dilakukan setiap 2 hari sekali pada penyimpanan hari ke-2, ke-4, ke-6, ke-8, dan ke-10. Hasil dari setiap parameter dibandingkan dengan menggunakan Rancangan Acak Lengkap (RAL) dan analisis menggunakan three way ANOVA. Hasil penelitian menunjukkan bahwa peningkatan nilai WVTR pada kedua kemasan dipengaruhi oleh peningkatan RH lingkungan. Nilai kuat tarik pada kedua kemasan dipengaruhi oleh bahan penyusun masing-masing kemasannya saja, bukan oleh kondisi lingkungan penyimpanannya. Nilai elongasi kedua kemasan dipengaruhi oleh RH lingkungan penyimpanannya yang dapat mengubah sifat dari bahan penyusunnya. Dari pengamatan mutu produk selama penyimpanan 10 hari dapat dinyatakan bahwa pengemasan produk dengan bioplastik hanya dapat mempertahankan mutu visual produk pada penyimpanan suhu rendah., Horticultural products are easily damaged products, usually caused by improper postharvest handling, especially in packaging. Plastic packaging is widely used as a popular packaging material but is not environmentally friendly. Therefore its use can be replaced with bioplastic. This study aims to examine the characteristics of bioplastic packaging made from starch and High Density Polyethylene (HDPE) with variations of storage conditions and to compare the value of quality changes on fresh products to packaging during storage. Characteristic testing was carried out by observing the Water Vapor Transmission Rate (WVTR) parameters and mechanical properties of both types of packaging during 8 hours of storage at temperature variations of 16 ˚C, 25 ˚C, and 30 ˚C, also RH variations of 18%, 51%, 79%, and 90%. Quality change testing was carried out using cavendish bananas by observing the parameters of respiration rate, weight loss, color change, and the mechanical properties of the packaging after being stored for ten days with temperature variations of 16 ˚C and 25 ˚C. Observations on the product were carried out every two days on the 2nd, 4th, 6th, 8th, and 10th day of storage. The results of each parameter were compared using a Completely Randomized Design (CRD) and analyzed using three-way ANOVA. The results showed that the increase in WVTR value on both packages was affected by an increase in environmental RH. The tensile strength value of both packages is influenced by the constituent materials of each package, not by the environmental conditions of storage. The elongation value of

Judul: Application of starch-based plastics (bioplastics) as packaging material for horticultural products (tomato and bell pepper)
Abstrak: One of the post-harvest handling for minimize the losses of horticultural product was regulating the storage temperature and packaging technique. The objective of this research was to determine the cold storage’s characteristic of agricultural product from the climacteric products (tomato) and non-climacteric products (bell pepper) that were packed by the fruit bag packaging from bioplastic compared with the HDPE. The packed product stored on three levels of storage temperature (5, 10 and 15oC) for 21 days and every three days the product was for respiration rate, weight losses, hardness, the changing of fruit color, total soluble solids and vitamin C content. The result of the research showed that bioplastic packaging could delay the climacteric phase of tomato until the 21st day of storage, longer than packed by the HDPE. However the bell pepper packed by the bio-plastic started the senescence phase since the 12th days of storage, faster than packed by HDPE. Bio-plastic packaging was un-appropriate for low temperature (5-10 oC) storage. Tomato and bell pepper packed by the bio-plastic were giving better color change and hardness during the storage temperature of 15 oC. Based on the ratio changing a*/b*, the tomato shelf life stored on the temperature of 15 oC with using the bio-plastic (29 days) was longer than using HDPE (25 days). The bell pepper with using the bio-plastic had lower shelf life than bell pepper using HDPE on all temperature levels.
