Abstract

Increasing tomato production requires special handling to increase longer shelf life by applying chitosan and modifying storage temperatures. Chitosan is a chitin derivative whose function is similar to wax compounds so that it is able to inhibit metabolic activity. Storage temperature of 10°C can extend shelf life and maintain the physical quality of tomatoes. This study aims to determine the effect of chitosan administration, the effect of storage temperature, and the effect of the combination of chitosan and storage temperature on the physical quality of tomatoes. This study used a Factorial Complete Randomized Design, the first factor was tomatoes without chitosan coating (K0), and tomatoes with chitosan coating (K1) = shrimp shell, (K2) = crab shell, (K3) = fish scales using the same concentration of 6%. The second factor is storage temperature (T1) = room temperature (26-32°C) and (T2) = temperature 10°C.  The changes observed are shrinkage in weight, color, texture, aroma, taste based on organoleptic test (hedonic test). Data analysis using ANOVA at 5% level and BNJ follow-up test at 5% level. The results showed that the use of crab chitosan (K2) had an effect on weight loss (0.42%). Storage temperature of 10°C (T2) affects weight loss (5.04%). The best treatment combination for weight loss (0.07%) and color (7.40) was crab chitosan and temperature of 10°C (K2T2), while the best treatment combination for texture (7.56), aroma (7.08), and taste (7.16) was fish scales and temperature of 10°C (K3T2). In general, the best treatment is chitosan fish scales and a temperature of 10°C (K3T2).

Abstract

Tanaman Jeruju (Acanthus ilicifolius L.) merupakan salah satu jenis mangrove yang memiliki banyak manfaat, salah satunya adalah pemanfaatannya untuk membuat teh dengan campuran jahe (Zingiber officinale). Penelitian ini menggunakan metode eksperimen dengan analisis data kuantitatif untuk menguji kadar antioksidan dan kadar flavonoid pada berbagai formulasi, yaitu 80%: 20%, 70%: 30%, 60%: 40%, dan 50%: 50%. Selain itu, penelitian ini juga menggunakan metode survei dengan analisis data kualitatif untuk menguji sifat organoleptik. Hasil penelitian menunjukkan bahwa formulasi dengan 50% jeruju dan 50% jahe memiliki kadar antioksidan dan kadar flavonoid total tertinggi. Dari segi organoleptik, formulasi 60%: 40% mendapatkan nilai tertinggi dari segi kesukaan yaitu 56%, sedangkan dari segi aroma, formulasi 60%: 40% mendapatkan nilai tertinggi yaitu 75%. Dari segi rasa, formulasi 50%:50% mendapatkan nilai tertinggi yaitu 75,6%, dan dari segi warna, formulasi 50%:50% mendapatkan nilai tertinggi yaitu 80,4%.

Abstract

This study aimed to determine the effects of various concentrations of growth regulators (ZPT) derived from mung bean sprout extract on the vegetative growth of Solanum lycopersicum, as well as the effect of aloe vera extract–based botanical pesticide on pest infestation intensity, either independently or in combination. The study employed a two-factor randomized block design consisting of ZPT concentrations (0%, 20%, 30%, 40%, 50%) and botanical pesticide concentrations (0%, 15%, 40%, 65%, 90%), each with three replications. The results showed that mung bean sprout extract–based ZPT significantly affected all vegetative growth parameters. The 50% concentration produced the greatest plant height (72.93 cm) and number of leaves (70.47), while the highest number of branches was obtained at the 20% (12.67) and 40% (12.53) concentrations. The botanical pesticide made from aloe vera extract significantly reduced pest infestation intensity, with the 65% and 90% concentrations classified as light damage (<25%), while the control (0%) showed very severe damage (>85%). The findings indicate that mung bean sprout–based ZPT effectively improves vegetative growth, and aloe vera–based botanical pesticide effectively suppresses pest attacks; however, their separate application is more optimal for achieving specific targets.
