Abstract

Hydroponics is a farming method in which plant nutrients are provided by a nutrient solution dissolved in water. Hydroponic systems are classified into two types, namely substrate systems and systems without substrate. The media used in hydroponics is organic media. Organic media have different physical and chemical structures compared to inorganic media. This media has durability as a strong support which has a good effect on plants such as being a good nutrients storage place. Green mustard plants with fibrous roots that grow and spread in all directions, no plants form around the soil surface. Mustard greens have short, straight stems that are planted on the ground. The leaves on the green mustard plant are round, glabrous, and light to dark green in color.

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 effectiveness of auxin (IBA) and cytokinin (BAP) application on avocado (Persea americana) in improving grafting success. The method used was a factorial randomized block design (RBD) of 3×3 with three replications. The observed parameters included the percentage of graft survival, time to bud emergence, number of buds, bud length, and number of leaves. The results showed that the application of IBA and BAP significantly affected the time to bud emergence and bud length, but had no significant effect on the percentage of graft survival, number of buds, and number of leaves. In conclusion, growth hormones can accelerate the initial physiological response in grafting, although they do not always impact overall vegetative growth.  Keywords: Avocado, BAP, Grafting, IBA, Persea americana

Abstract

Red guava (Psidium guajava L.) has antioxidants that can prevent or inhibit the oxidation process inhibit the oxidation process. The purpose of the study was to determine the amount of comparison the highest vitamin C and antioxidant levels between fresh red guava and packaged red guava. red guava fruit in packaging. The research method used was quantitative quantitative method by free radicals DPPH (Diphenyl Picrylhydrazyl). The results of the study found that fresh red guava vitamin C guava has a level of 0.70 mg/100 grams higher than the packaged vitamin C of 0.43 mg/100 grams packaged at 0.43 mg/100 grams. IC50 value of red guava value of 194.22 ppm which is categorized as moderate, while the IC50 value in the packaging 516.59 ppm is categorized as very weak.
