KAJIAN AKTIVITAS ANTIBAKTERI EKSTRAK KULIT PISANG RAJA (Musa Paradisiaca var. Raja) DAN SERAI (Cymbopogon Citratus) TERHADAP UMUR SIMPAN BAKSO AYAM

ABSTRACT The purpose of this study was to determine the interaction effect of storage time and concentration of plantain peel extract and lemongrass on organoleptic characteristics (color, aroma, texture, and elasticity) and total microbes in chicken meatballs. This study used a 2-Factorial Completely Randomized Design method. The first factor was storage time with three levels, namely 0 days (T0), 2 days (T1), and 4 days (T2. Meanwhile, the second factor was the concentration of plantain peel and lemongrass extract with three levels, namely 0% (C0), 30% plantain peel extract + 20% lemongrass extract (C1), 20% banana peel extract + 30% lemongrass extract (C2), and 25% banana peel extract + 25% lemongrass extract (C3). Observation variables were organoleptic tests which included color, aroma, texture, elasticity, and shelf life after treatment based on the results of the total plate count (TPC) calculation. The results show that the 2-day storage period with the addition of 25% plantain peel extract and 25% lemongrass extract (T1C3) was the best treatment for organoleptic characteristics (color, aroma, texture, and elasticity). Based on the results of the study, it can be concluded that the administration of plantain peel extract and lemongrass was able to maintain the quality of chicken meatballs for two different days compared to the control. Treatment with a storage period of 2 days with 25% plantain peel extract and 25% lemongrass extract (T1C3) was the best treatment that was most favored by the panelists and had the least number of microbial colonies.Keywords: Meatballs, preservatives, banana peel extract and lemongrass, storage time.ABSTRAKTujuan penelitian ini adalah untuk mengetahui pengaruh interaksi lama penyimpanan dan konsentrasi ekstrak kulit pisang raja dan serai terhadap uji organoleptik (warna, aroma, tekstur dan kekenyalan) dan total mikroba pada bakso ayam.

Changes in The Number of Mold and Acceptance Rate of Kappaphycus alvarezii Jelly Candy Packed with Edible Film Gelatin-CMC During Storage

This study aimed to analyze changes in the number of molds and the level of panelist acceptance of K. alvarezii jelly candy packaged using gelatin-CMC edible film during storage. The method used in this study is a laboratory experimental method which consists of two stages, namely preliminary research which aims to determine the best edible film formula to be used as jelly candy packaging and the main research to analyze changes in the number of molds and the level of acceptance of appearance, taste, aroma and texture of jelly candy that has been packaged using a gelatin-CMC edible film during storage. Storage for 60 days was converted to 15 days in a climatic chamber with a temperature of 40 ℃ and a humidity of 75%. Sampling was carried out every 3 days. The research design used linear regression to see the relationship between storage time and test parameters. The results of the preliminary study showed the best formula for edible film, namely 1% gelatin, 0.3% bees wax, 0.75% CMC, and 0.3% glycerol which resulted in a water vapor transmission rate of 18.60 g/m2/24 hours. The results of the main study showed that storage time had a moderate effect on mold. Mold was detected on the last day of observation, storage time had a very strong effect on the level of acceptance which decreased with storage time. The organoleptic value of jelly candy packaged using gelatin-CMC edible film was still acceptable to the panelists until the 36th day of storage.

ANALISIS KADAR POLIFENOL DAN AKTIVITAS ANTIOKSIDAN YANG TERDAPAT PADA EKSTRAK BUAH : STUDI KEPUSTAKAAN

ABSTRACTPolyphenols are one of the largest categories of phytochemicals and are the most widely distributed among various types of plants and fruits. Polyphenols can also inhibit, prevent, and reduce oxidation by free radicals, which are good for health. Analysis of polyphenol content starts from the sample preparation process which includes the extraction of solid and liquid samples. The types of solvents commonly used for extraction are ethanol, methanol, and acetone. Furthermore, the analysis of polyphenol levels uses the Folin-Ciocalteau analysis method. The results of the review show that ripe bisbul fruit extract (Diospyros blancoi A. DC.) which was extracted using ethanol as a solvent had the highest polyphenol content and yield of several fruit extracts reported in this review. Meanwhile, the extract of green grapes (Vitis vinifera Linn. Var. Chinsiang) which was extracted using ethanol as a solvent had the lowest levels and yields of polyphenols. The highest antioxidant activity was shown by samples of red dragon fruit extract (Hylocereus polyrhizus (f.a.c weber) britton & rose). Meanwhile, the lowest antioxidant activity was shown by samples of Watermelon (Citrullus lanatus) fruit extract.Keywords: Pholyphenol, Extracts, Solvents, Folin CiocalteauABSTRAKPolifenol adalah salah satu kategori terbesar dari fitokimia yang paling banyak penyebarannya diantara berbagai jenis tanaman dan buah-buahan. Polifenol juga dapat menghambat, mencegah, mengurangi oksidasi oleh radikal bebas sehingga baik untuk kesehatan. Analisis kadar polifenol dimulai dari proses preparasi sampel yang meliputi ekstrasi sampel padat dan ekstraksi sampel cair. Jenis pelarut yang umum digunakan saat pengekstrakan yaitu etanol, metanol, dan aseton. Selanjutnya analisis kadar polifenol menggunakan metode analisis folin ciocalteau. Hasil review menunjukkan Ekstrak buah bisbul matang (Diospyros blancoi A.
