This research was conducted to determine the dose of shallot skin extract that is effective for controlling Spodoptera litura F. This research was carried out for 2 months at the Biology Laboratory, Faculty of Agriculture, Santo Thomas Catholic University, Medan. The research design used was a Non-Factoral Completely Randomized Design (CRD) consisting of five treatments and each treatment was repeated four times to form 20 experimental units of Red Onion Skin Soaking (K), namely: K0 = 0% (Control), K1 = 20 gr/liter of water, K2 = 40 gr/liter of water, K3 = 60 gr/liter of water, and K4 = 80 gr/liter of water. The parameters observed were pest mortality, 50% death time and larval behavior after application. From the research results, it can be seen that administering shallot skin extract at the highest dose, namely 80 g/L, can be quadratically used as a botanical insecticide to control S. litura pests with a death time of 27 hours

This research aims to determine the effect of shallot extract concentration and soaking time on the growth of pepper plant stems. This research was carried out at the Unika Santo Thomas Medan agricultural experimental field Jl. Setia Budi no. 479, Tanjung Sari, Medan. With a height of around 32 meters above sea level (meters above sea level). This research was conducted from March to May 2023. This research used a factorial Randomized Block Design (RAK) consisting of 2 factors. The first factor is the concentration of shallot extract (K) and the second factor is the soaking time (P). The first factor is the concentration of shallot extract (K) consisting of 4 treatment levels, namely: K0: 0% (control), K1: 30% (30 mL of shallot extract + 70 mL of distilled water), K2: 60% (60 mL of shallot extract + 40 mL distilled water), K3: 90% (90 mL shallot extract + 10 mL distilled water). The second factor is the length of soaking of pepper plant cuttings (P) consisting of 3 treatment levels, namely: P1: 3 hours, P2: 6 hours, P3: 9 hours. Based on the research results, it can be seen that the concentration of onion extract has no effect on the percentage of live cuttings of pepper plant cuttings, but it has a real influence on the length of the shoots with the highest shoots obtained at a concentration of 93.33% at a concentration of 83.77% for the number of leaves. the most. Regarding the number of roots, a concentration of 78.66% produced the highest number of roots.

Heavy metal pollution in urban soil is an increasingly urgent problem today. High concentrations of heavy metals in soil can cause long-term risks to ecosystems and humans. It is necessary to find a solution to reduce heavy metal pollution, especially through phytoremediation using patchouli plants. Research on patchouli plants was carried out using a non-factorial randomized block design; consists of 1 factor, namely the concentration of the heavy metal Cd which consists of five levels: K0= 0 ppm, K= 85 ppm, K2= 170 ppm, K3= 255 ppm, K4= 340 ppm. Each treatment was made in 3 replications where each experimental unit consisted of 3 plants. Data on essential oil content and uptake of the heavy metal Cd from the results of this study were analyzed using IBM SPSS Statistics 20, then the treatment that showed a real influence on the observed variables was continued with the Duncan's Multiple Range Test (DMRT) at a confidence level of 5%. The parameters observed were root length (cm), root volume (cm3), root wet and dry weight (g), shoot wet and dry weight (g), essential oil content (ml/g), cadmium uptake in the roots and shoots. (ppm). The research results show that patchouli plants are classified as plants that are resistant to heavy metal stress, this can be indicated by their ability to grow and develop well at concentrations ranging from 0 ppm to 255 ppm. Based on the absorbed Cd content, patchouli plants are classified as phyto-extraction plants because they are able to accumulate greater Cd metal in their shoots compared to the Cd content in their roots. Likewise, the production of essential oils produced is not influenced by the concentration of Cd metal.

Mucuna bracteata plants can be propagated in two ways: generatively and vegetatively. Vegetative propagation is done through cuttings, while generative propagation uses seeds. In 1999, Mucuna bracteata found it very difficult to produce flowers, fruits, and seeds. Due to this difficulty, propagation can be done through cuttings. This study uses a Non-Factorial Randomized Block Design (RBD) with 4 Treatments (P) and 6 Replications (U). The concentration of watering consists of 4 levels: P0 (0 ml), P1 (50 ml), P2 (150 ml), and P3 (250 ml). Meanwhile, the soaking duration also consists of 4 levels: P0 (0 minutes), P1 (5 minutes), P2 (10 minutes), and P3 (15 minutes). The results of the study showed that the interaction between the concentration of watering with MOL (Microorganism Local) from banana stems and the soaking duration did not have a significant effect on all parameters. Various concentrations of watering with MOL from banana stems and soaking duration significantly affected the growth of Mucuna bracteata. Although statistically, it did not show a significant effect, several treatment combinations could be observed, such as U6P3, which showed the highest root weight (15.44 grams). Then, the vine length was 117.1 cm, the number of leaves was 20, and the number of nodules was 11. As the highest values from P3, this shows the highest concentration of watering and soaking duration with MOL from banana stems. Thus, this effort can reduce agricultural waste and pathogens.

Biomass Analysis of Mucuna bracteata DC Due to the Application of Coffee Husk Waste as an Organic Nutrient Source. Mucuna bracteata DC is a cover crop that plays a crucial role in soil conservation and soil fertility improvement. This study aims to analyze the effect of liquid organic fertilizer (LOF) derived from coffee husk waste on the biomass growth of Mucuna bracteata DC, particularly in terms of fresh shoot weight, fresh root weight, dry shoot weight, and dry root weight. The research was conducted at Jalan Kuali No. 50, Medan Petisah District. The experiment was designed using a Completely Randomized Block Design (CRBD) with a single-factor treatment consisting of seven LOF dosage levels: K0 (no treatment), K1 (5 mL/polybag), K2 (10 mL/polybag), K3 (15 mL/polybag), K4 (20 mL/polybag), K5 (25 mL/polybag), and K6 (30 mL/polybag), with four replications, totaling 28 experimental plots. The results showed that the application of coffee husk LOF significantly affected the biomass growth of Mucuna bracteata DC. The highest fresh shoot weight (9.51 g) and dry shoot weight (2.14 g) were recorded in treatment K6 (30 mL/polybag), whereas the highest fresh root weight (2.29 g) and dry root weight (0.32 g) were observed in treatment K5 (25 mL/polybag). Higher LOF doses generally increase plant biomass up to an optimal threshold, beyond which nutrient absorption efficiency by roots declines. Overall, the optimal LOF dosage for maximizing biomass growth in Mucuna bracteata DC ranges between 25–30 mL/polybag. The use of coffee husk waste as an organic nutrient source presents a sustainable alternative for improving plant productivity while reducing dependency on synthetic fertilizers.
