Tomato is a plant of solanaceae family, has short stems, and grows well in tropical climates. Tomatoes have vegetative and generative growth phases. The availability of nutrients largely determines the vegetative growth phase. The purpose of the study is to determine: (1) the effect of vermicompost on tomato growth, (2) the effect of NPK fertilizer treatment on tomato growth, (3) the interaction effect of vermicompost and NPK fertilizer on tomato growth. The research was conducted using experimental methods. The research was carried out from April to July 2021. The research design was a 4 x 5 complete random factorial design with three repetitions. NPK fertilizer consisted of 4 levels of treatment doses, while vermicompost consisted of 5 levels of treatment doses. The research finding shows that the application of NPK fertilizer of 0.8 grams per plant significantly affected stem diameter, the number of compound leaves, leaf length, and stem height of tomatoes. Treatment of vermicompost of 1.8 kg of vermicompost resulted in the best stem diameter, number of compound leaves, leaf length, and stem height. The combination of vermicompost and NPK fertilizer had no significant effect on stem diameter, the number of compound leaves, leaf length, and stem height of tomatoes.

The use of inhibitors is one of the most effective ways to control corrosion. The study aims to determine and examine more deeply the effect of variations in the concentration of organic inhibitors from Moringa leaf extract on the corrosion rate of A36 steel material in seawater media. Moringa leaf extract's effectiveness in inhibiting the corrosion rate of A36 steel material in seawater media is also determined. This research was conducted by immersing specimens with inhibitor concentrations of 0 ppm, 100 ppm, 200 ppm, 300 ppm, 400 ppm, and 500 ppm for seven days of immersion. The corrosion rate is calculated using the weight loss method. The results showed that the corrosion rate decreased with the inhibitor concentration in the corrosion media. The inhibitor concentration of 500 ppm Moringa leaf extract was able to inhibit the corrosion rate optimally. It is indicated by the smallest corrosion rate value of 1.07 mpy. On the other hand, the inhibitor efficiency increases with the inhibitor concentration in the corrosion media. The highest inhibitor efficiency was 78.71% at the addition of 500 ppm inhibitor to the solution.
