Abstract

The use of biological agents is an effective way to prevent the negative impacts of excessive synthetic chemical pesticide use. Trichoderma sp., a saprophytic fungus, acts as a biocontrol agent against various phytopathogenic molds and is more commonly found in rooted soil and leaves than in stems or fruits. This study aims to identify the characteristics and presence of Trichoderma sp. in horticultural land using the baiting method. Isolation was carried out by collecting fungi grown on rice, corn, and coconut bait using an inoculation needle. Three Trichoderma sp. isolates were obtained from chili and bamboo root soil using rice and corn bait. The results showed that the three isolates had similar characteristics: colonies were dark green, circular in shape, powdery in texture, and had entire margins. Microscopically, the isolates featured branched and upright conidiophores arranged vertically, short and thick phialides, round greenish conidia, and septate hyphae resembling threads.

Abstract

This study aims to develop a peel-off gel mask formulated from orange peel eco-enzyme solution and its physical characteristics and antibacterial activity against Staphylococcus epidermidis. The resulting gel mask has organoleptic characteristics of transparent brownish color, thick gel consistency, and fresh sour-sweet aroma. Physical characteristic tests showed that the gel mask meets pharmaceutical requirements, namely: pH value 4.5-6.5, spreadability 5-7 cm, and drying time 15-30 minutes. The mask showed good homogeneity without aggregates, although it was a little difficult to peel off, but it was not easily torn, and had stable thermodynamic stability. Antibacterial tests revealed that the peel-off gel mask made from orange peel eco-enzyme was effective in inhibiting the growth of Staphylococcus epidermidis. The diameters of the inhibition zones of the P1, P2, and P3 masks were 2.5 ± 0.5 mm, 2.1 ± 0.35 mm, and 1.5 ± 0.5 mm, respectively. These results indicate the potential of eco-enzymes from orange peel as active ingredients for peel-off gel mask formulation for skin care, especially in inhibiting acne-causing bacteria.

Abstract

This study aims to determine the effect of natural Plant Growth Regulators (PGR) from rice washing water on the growth of grafting plants through the stem cutting method. The research method used in this study was a Completely Randomized Design (CRD) consisting of 3 treatments and each treatment was repeated 8 times. The experiments carried out were as follows: P1 (control, without soaking in PGR rice washing water), P2 (soaking for 10 minutes in PGR rice washing water), and P3 (soaking for 20 minutes in PGR rice washing water). The parameters observed included plant height, number of leaves, and leaf area. The results showed that the treatment of soaking for 10 minutes in natural PGR rice washing water was the best treatment because the average value for the number of leaves tended to be high and affected the leaf area. The control treatment (without soaking) produced the highest plants. Soaking for 20 minutes (P3) tended to only increase the average growth value for each parameter each week.

Abstract

Onion are one of the many types of shallots that exist in the world. Shallots are a member of the Allium genus which is usually used as a cooking spice. Demand for shallots will continue to increase along with people's needs that continue to increase. Hydroponics is a method of growing crops without using soil, usually using cocpeat, husks and sand as a substitute for soil. One hydroponic model that is easy to implement is the wick system method, where in this system the plants absorb water through the wick. The parameters observed were plant height, root length and number of tubers. The results of the research showed that the planting medium did not have a real influence on plant height and number of tubers, but on root length the planting medium had a real influence. The best planting medium for growing tall shallots is husk media: cocopeat (1:1) with the highest score of 27.90. Meanwhile, the root length and number of shallot bulbs were highest in the husk: sand (1:1) media with values of 16.00 and 6.22.

Abstract

Inulin is a type of prebiotic which is generally produced from artichoke plants (Helianthus tuberosus). Considering the diversity of tubers in Indonesia, in this study the prebiotic potential of inulin was tested from various tubers, namely gembili tubers (Dioscororea esculenta), dahlia tubers (Dahlia Pinnata L.) and yakon tubers (Smallanthus sonchifolius). In this study, the prebiotic activity of tubers was tested against bifidiobacterium bacteria. Bacterial growth was carried out on MRS media, which is added with inulin from each tuber as much as 1% b/v gram. In addition to that negative control group and positive control group (comercial inulin) were added. During the incubation time of 24 hours, 48 and 92 hours, all varian group has positive correlation with the growth of Bifidiobacterium. The bigger correlation was found in Gembili tuber group with R = 0,9 and had the maxiumun bifidiobacterium colony which reached 14.4 x 108 CFU/ml.
