Abstract

Causes of degenerative diseases are caused by activities and unhealthy lifestyle. unhealthy lifestyle which in turn triggers free radicals. free radicals are moleculs that are not oxidized which cause the formation of new molecules that can damage body cells. free radicals can be overcome by giving natural antioxidants, one of which is form the olive plant (Olea europaea L.).The purpose of this study was to determine the effect of temperature treatment on antioxidant activity in olive leaves based on leaf age by calculating the IC50 value. The method used in this research is the DPPH method. Based on the results of the study, it can be concluded that the temperature of 31.6°c in young leaves according to calculations is categorized as a strong antioxidant because it provides a calculated value of 82.778 ppm and 165.093 ppm on old leaves and classified as moderate antioxidants, while temperature of 44°c give dominant level under 31.6°c with IC50 values 123.78 ppm for young leaves and 165.170 ppm for old leaves and classified as moderate antioxidants according to the theory that compounds that have very strong antioxidant activity values IC50 values are less than 50 ppm, strong if the IC50 are between 50 and 100, moderate antioxidant if the IC50 values are feasible 100-250 ppm, weak if the IC50 value is 250-500 ppm and inactive if the IC50 value is more than 500 ppm. and vice versa related to the selection of leaf age also affects the level of antioxidant activity seen from the comparison of results from the two treatments that young leaves have a higher level of antioxidant activity than old leaves in counteracting free radicals.Keywords : Temperature, Antioxidant, Olive (Olea europaea L.), DPPH.ABSTRAKPenyebab penyakit degeneratif disebabkan karena aktivitas dan pola hidup yang kurang sehat. Pola hidup kurang sehat yang pada akhirnya memicu radikal bebas. Radikal bebas adalah molekul yang tidak teroksidasi yang menyebabkan terbentuk molekul baru yang dapat merusak sel tubuh. Radikal bebas dapat diatasi dengan pemberian antioksidan salah satunya dari tumbuhan zaitun (Olea europaea L.). Tujuan dari penelitian ini adalah untuk mengetahui pengaruh perlakuan suhu terhadap aktivitas antioksidan pada daun zaitun berdasarkan umur daun melalui perhitungan nilai IC50. Metode yang digunakan dalam penelitian ini adalah metode DPPH. Berdasarkan hasil penelitian dapat disimpulkan bahwa perlakuan suhu 31.6°C pada daun muda  menurut perhitungan IC50 dikategorikan sebagai antioksidan kuat karena memberikan nilai hasil perhitungan IC50  sebesar 82.778 ppm dan 165.093 ppm pada daun tua dan tergolong antioksidan sedang, sementara pada perlakuan suhu 44°C memberikan pengaruh lebih rendah dibandingkan dengan perlakuan suhu 31.6°C dengan nilai IC50 sebesar 123.78 ppm untuk daun muda dan 165.170 ppm untuk daun tua dan tergolong antioksidan sedang sesuai teori bahwa senyawa yang memiliki nilai aktivitas antioksidan sangat kuat jika nilai IC50 kurang dari 50 ppm, kuat apabila nilai IC50 bernilai antara 50 sampai 100, antioksidan sedang apabila jika nilai IC50 bernilai 100-250 ppm, lemah jika nilai IC50 bernilai 250-500 ppm dan tidak aktif jika nilai IC50 bernilai lebih dari 500 ppm, begitupun sebaliknya terkait pemilihan umur daun juga berpengaruh terhadap tinggi rendahnya aktivitas antioksidan dilihat dari perbandingan hasil dari kedua perlakuan bahwa daun muda memiliki tingkat aktivitas antioksidan lebih tinggi dibandingkan dengan daun tua dalam menangkal radikal bebas.Kata Kunci : Suhu, Antioksidan, Zaitun (Olea europaea L.), DPPH.

Abstract

Dendrobium orchids come in a variety of colors, shapes, and beauty that are in great demand. The process of growing orchids requires special handling of an appropriate growing environment, such as proper planting media and nutrients that can stimulate orchid growth. This type of thin liquid film media is the use of liquid media with an immersion system while vermiculite and perlite media have almost the same properties. However, vermiculite has a higher water absorption capacity than perlite. Nanobubbles are bubbles with 1-100 nm that can live more stably in water. This study aims to influence the type of media and the addition of Nanobubbles O2 on the growth of Dendrobium burana Green × Ong Ang Ai Boon orchid plantlets. This research was carried out from November to December 2022 at the PT. Java Indo Arjuna Singosari, Malang. This study used a completely randomized design (CRD) with 10 treatments, namely solid MS, gaviota solid, thin liquid film, thin liquid film + NBs O2, vermiculite, vermiculite + NBs O2, perlite, perlite + NBs O2, vermiculite + Perlite, vermiculite + perlite + NBs O2 with 4 replications. The data were analyzed descriptively and the Manova test. The results showed that the vermiculite + NBs O2 treatment had the potential to increase the length of plantlets by 13.80 mm, the wet weight of plantlets by 0.30 g, the percentage of live plantlets by 100% whereas in the vermiculite + perlite treatment has the potential for the first root growth to appear, namely 5 HST. The vermiculite treatment had the potential to increase the highest number of leaves by 5 leaves, whereas in the leaf color treatment the solid MS treatment had a more intense green color.

Abstract

Plants need nutrients which are then provided through fertilizers, but this can cause long-term problems due to limited absorption by plants so recently implemented NBs technology that can help reduce environmental pollution. This study aimed to determine the effect of NBsO2, NBsH2, NBsCO2, NBsN2 and, NBsO3 on the growth of Phalaenopsis sp. orchid plants. The research method was a complete randomized design (RAL) with 7 treatments (control without application of fertilizer and NBs, foliar fertilizer, NBsO2, NBsH2, NBsCO2, NBsN2, NBsO3) and 4 repeats. NBs were made using a nanogenerator with a flow of 5 liters/ minute and induced for 15 minutes. The data analysis used is the Multivariate Analysis of Variance (MANNOVA) test. The control and NBs treatments were given by dropping 5 ml on each orchid plant. The results showed that leaf length, number of leaves, plant weight and number of plant roots NBsN2 treatment had the best effect, while on root length, NBs O2 treatment had a better effect than other treatments. The application of foliar fertilizer is less effective to meet plant growth needs. At the same time, NBs are more effective because they are very small making it easier for plants to absorb.

Abstract

The growth and development of orchids take a relatively long time, while the demand for high-quality orchids continues to increase significantly. Tissue culture is a technique of isolating plant parts in organs, tissues, and cells and then culturing these plants on artificial media in a sterile environment. Tissue culture techniques can reproduce plants in a relatively short time, with the same properties and quality, so efforts to optimize tissue culture with technology are the right solution, one of which is using nanogenerator technology that produces Nanobubbles (NBs). NBs are one of the nanotechnologies that are ?100 nm in size with induced gas needed by plants. This study aims to determine the effectiveness of growth and development from the induction of NBsN2 and NBsO2 in Cattleya sp. planlet in vitro culture. This research method uses in vitro culture with a Randomized Group Design. The results of the MsO treatment showed higher weight than other treatments, with a total plant weight value of 0.3550 g and a total plant height value of 1.3983 cm. Murashige-Skoog + NBsNitrogen (MsN) treatment showed higher root length than other treatments with a total value of 1.2367 cm. In the treatment of Ms, MsO, OJ and NJ, a live percentage of 83-100% was observed. The statistical test results indicate that NBs positively affect Cattleya sp. plantlets. This effect includes increasing plant weight, height, and root length and promoting new shoots growth. Additionally, nitrogen supplements play a role in colour changes, indicating the plant's health and photosynthetic efficiency. In the treatment with Induction O2, the initial colour changes from Strong Yellow Green (141 D) to Strong Yellowish Green (141 C), while in the treatment with Induction NBsN2, the initial colour changes from Strong Yellow Green (141 D) to Deep Yellow Green (141 B).

Abstract

In in vitro culture, light and nitrogen absorption play crucial roles in the growth of Dendrobium sp orchids. Light affects plant absorption; thus, nitrogen must be added in the right amount for optimal growth. Nanobubbles (NBs) technology has been developed to convert nitrogen into smaller particles, facilitating plant absorption. This study aims to investigate the effects of color spectrum and N2 NBs on the growth of Dendrobium sp orchids. The experimental research method involved different treatments of media (MS; MS+ZPT; MS+ NBs N2; MS+ZPT+NBs N2) and color spectrum (white, red, blue, red-blue). Data on live percentage, plantlet legth and plantlet weight were analyzed descriptively and statistically (normality, homogeneity, multivariate, and Games-Howell tests). The results showed that the highest percentage of live plantlets, 97.91%, was found in the treatments with red and red-blue color spectrum. The red-blue color spectrum significantly increased the plantlet weight by 0.363 g in the MS treatment, and the application of red color spectrum potentially increased the plantlet length by 1.707 mm in the MS+ZPT treatment. The addition of NBs N2 in the subculture media showed potential for 100% live plantlet percentage in the MS+NBs N2 treatment.

Abstract

Strawberry plants are a type of plant that grows extensively in Indonesia. Some studies show that Strawberries (Fragaria x ananassa) are a source of bioactive compounds, rich in ascorbic acid, anthocyanins and phenol compounds, and have high levels of antioxidants. Strawberries have compounds that provide pigment and antioxidant activity, namely anthocyanins. This study aims to detect secondary metabolite compounds in strawberry fruit extract (Fragaria x ananassa) using Thin Layer Chromatography (TLC) with a mobile phase containing butanol, acetic acid, and aqua-distillate (4:1:1) and infrared spectrophotometry. The results of phytochemical screening tests showed that the strawberry extract contained secondary metabolite compounds, including alkaloids, flavonoids, tannins, and saponins. TLC with the Rf value in Strawberry fruit extract results in 0.38. The results of the infrared spectrophotometry analysis indicate the presence of functional groups, including C-H, CO, OH, C꓿C, and ꓿C-O-C, which corroborate the results of TLC, suggesting that the strawberry extract contains anthocyanins.
