Abstract

Arabica coffee is coffee that has a special taste that is more complex than the Robusta, Ekselsa, or Liberica coffee types. The distinctive taste is caused by the presence of secondary metabolite compounds present in coffee cherries. The content of secondary metabolite compounds in coffee is formed when it becomes coffee cherries, in the post-harvest process, and the roasting process of coffee beans. Several regions in Indonesia are coffee bean producing areas, including Aceh, Bogor, Bandung, Situbondo and Temanggung. The purpose of this research was to determine the content of phytochemical compounds, total phenol content, and antioxidant activity in the five samples of Arabica coffee beans with the natural process which were roasted at the same light to medium roasting level. The results showed that the water content ranged from 0,867 %-1,01 %, lightness 19,66 – 20,11, the degree of acidity 5,15 – 5,33, and the total dissolved solids were 1,84 – 1,96 °Brix. Phytochemical analysis on the five samples showed that each sample contained flavonoids, tannins, saponins, steroids, triterpenoids, and alkaloids with relatively the same value qualitatively. The analysis showed that the total phenol content was 8 316,52 – 8 576,76 mg/kg gallic acid equivalent. The antioxidant activity of samples from Bandung and Situbondo was not significantly different and had the highest activity among other samples. The results of the analysis of total phenol content and antioxidant activity showed a high degree of correlation between samples. ABSTRAKKopi Arabika merupakan kopi yang memiliki cita rasa khas dan lebih kompleks dibandingkan dengan jenis kopi Robusta, Ekselsa, atau Liberica. Rasa yang khas tersebut disebabkan oleh adanya senyawa metabolit sekunder yang terdapat pada buah kopi. Kandungan senyawa metabolit sekunder pada kopi terbentuk saat menjadi buah kopi, pada proses pascapanen, dan proses penyangraian biji kopi. Beberapa daerah di Indonesia merupakan daerah penghasil biji kopi, antara lain Aceh, Bogor, Bandung, Situbondo dan Temanggung. Tujuan dari penelitian ini adalah untuk mengetahui kandungan senyawa fitokimia, kandungan total fenol, dan aktivitas antioksidan pada kelima sampel biji kopi Arabika dengan proses natural yang disangrai pada tingkat penyangraian yang sama yaitu ringan hingga medium (light to medium). Hasil penelitian menunjukkan bahwa kadar air berkisar antara 0,867 %-1,01 %, kecerahan 19,66 - 20,11, derajat keasaman 5,15 – 5,33, dan total padatan terlarut adalah 1,84 – 1,96 Brix. Analisis fitokimia pada kelima sampel menunjukkan bahwa setiap sampel mengandung flavonoid, tanin, saponin, steroid, triterpenoid, dan alkaloid dengan nilai kualitatif yang relatif sama. Karakterisasi senyawa total fenol dilakukan dengan menggunakan metode Folin-Ciocalteu dengan senyawa asam galat sebagai pembanding. Hasil analisis menunjukkan bahwa kandungan total fenol setara dengan 8 316,52 – 8 576,76 mg/kg asam galat. Analisis aktivitas antioksidan sampel dilakukan dengan metode DPPH (2,2-difenil-1-pikrilhidrazil) dengan asam askorbat sebagai standar perbandingan. Aktivitas antioksidan sampel dari Bandung dan Situbondo tidak berbeda nyata dan memiliki aktivitas paling tinggi di antara sampel lainnya. Hasil analisis kandungan total fenol dan aktivitas antioksidan menunjukkan tingkat korelasi yang tinggi antar sampel.

Abstract

Nuggets are a product that should be stored frozen, but nuggets are often sold at inappropriate temperatures, causing physical changes such as pale color. Dayak onion extract can improve color appearance and provide added antioxidant value to tilapia nuggets. Quality testing of tilapia nuggets with Eleutherine palmifolia (Dayak onion) extract coatings has been investigated. The objectives of this research are to apply Dayak onion extract to improve the appearance of tilapia nuggets and to obtain tilapia nuggets with Dayak onion extract that meets SNI requirements. The results of organoleptic tests showed that panelists preferred tilapia nuggets with Dayak onion extract over commercial controls and nuggets. The panelists preferred tilapia nuggets with 100 ppm ethanol extract and 10000 ppm aqueous extract, both continued to the SNI conformity test. The sensory evaluation results based on SNI showed that the appearance of the tilapia nuggets with 100 ppm ethanol extract was significantly different. Adding Dayak onion extract to tilapia nuggets affected the lightness and yellowness of tilapia nuggets and gave a 'moderate orange' color to the tilapia nuggets with ethanol and aqueous extract. The selected tilapia nugget with 100 ppm aqueous Dayak onion extract meets all chemical, microbiological, and sensory requirements as SNI 7758:2013 concerning fish nuggets. Tilapia nuggets with Dayak onion extract had a brighter Moderate orange color and were preferred by panelists compared to controls and commercial fish nuggets that were moderate dark orange. Applying Dayak onion extract on tilapia nuggets can improve the appearance and it potentially contains natural antioxidants.

Abstract

The provision of quality and sufficient shrimp fry for production is largely determined by the management of maintenance during larval stadia. This study aims to obtain the best treatment of natural feed in the form of Spirulina sp. and Artemia sp. as feed supplements to improve the growth performance and survival rate of patin fish larvae. The experiment used a Complete Randomized Design consisting of 4 feed treatments and 3 replicates: A (Artemia sp. 100%), B (Artemia sp. 100% and Spirulina sp. 100%), C (Artemia sp. 50% and Spirulina sp. 50%), and D (Spirulina sp. 100%). The larvae with a density of 50 heads/L were kept in the aquarium and fed according to the treatment. The density of Spirulina sp. administered was 104–105 cells/mL maintained until day 7 according to the treatment. The parameters measured included growth performance, which included specific growth rate (SGR), survival (SR), absolute length growth (PPM), and analysis of larval digestive enzymes (amylase, lipase, and protease). The data were analyzed using one way-analysis of variance and continued with Duncan's Multiple Range Test with a 95% confidence interval using SPSS version 22.0. The results showed that the administration of Spirulina sp. produced better SGR, SR, PPM, amylase enzyme, lipase, and protease activities compared to the control (100% administration of Artemia sp.). The best treatment was given by 100% Spirulina sp. treatment. Keywords: Artemia sp., digestive enzymes, patin fish larvae, Spirulina sp.
