Abstract

ABC mix biological hydroponic nutrition is an innovation by developing the AB Mix hydroponic nutrition formulation (based on 100% chemicals) in collaboration with Liquid Organic Biofertilizer/LOB from LOB Plant PT. Great Giant Pineapple (PT.GGP). This invention is created in order to solve the problem of industries that want to produce hydroponic nutrients based on liquid organic biological fertilizer to reduce the concentration of chemicals in hydroponic nutrients. The aim of this invention are (1) to develop hydroponic nutrient products consisting of chemical fertilizers and biological fertilizers so that the use of chemicals can be reduced, (2) to produce patents granted regarding hydroponic nutrition based on chemical fertilizers and biological fertilizers, and (3) to apply the results of the invention to society and industry that requires the invention. The ABC Mix biological hydroponic nutrition product already has a patent with number IDS000006120 and has been implemented at Miftahul Huda Islamic Boarding School 606 through community service activities.

Abstract

Cauliflower is a vegetable with high economic value. However cauliflower production was decrease caused by crop failure resulting, pest and deseasse attack. Decrease of Cauliflower production related to soil fertility. One of attempts to overcome this problem is combining NPK fertilizer and setting of plant spacing to increase cauliflower production in Indonesia. The aims of this research is Firts: Determine the most effective dose of NPK fertilizer for growth and yield cauliflower, Seccond: Finding the optimal plant spacing to support growth and yield of cauliflower, and Third: indentifying best combinations of NPK fertilizer dosage and plant spacing to increasing growth and yield of cauliflower production. This research used a factorial Randomized Group Design (RAK) by two factors: NPK fertilizer dose (0 g/plot, 5 g/plot, 10 g/plot dan 15 g/plot), plant spacing (40 x 45 cm, 50 x 45 cm, and 60 x45 cm). Results of this research show that aplication doses of NPK fertilizer provides best results at an NPK fertilizer dose of 10 g/plot. Application of plant spacing did not show significant differences throughout observed of all parameters. Additionally, no interactions from combination of NPK fertilizer dosage and plant spacing cauliflower.

Abstract

Whiteflies are the main insect pests of Solanaceae plants, especially tomatoes. The need for tomatoes has not been met due to fluctuating production. Increasing tomato production to meet national needs can be done by controlling these two main insect pests. Control can be done using vegetable pesticides. These ingredients include tobacco leaves, citronella leaves, and Javanese chilies. This research was carried out in June - August 2024 at the Lampung State Polytechnic practicum area. The study used a randomized block design with 6 treatments and 4 replications. The six treatments consisted of six plant-based pesticide compositions based on tobacco leaves. The composition of the botanical pesticide made is A. 100% tobacco leaves, B. 50% tobacco leaves + 50% citronella leaves, C. 75% tobacco leaves + 25% citronella leaves, D. 50% tobacco leaves + 50% Javanese chili, E. 75% tobacco leaves + 25% Javanese chili, and F. 35% tobacco leaves + 35% citronella leaves, and 30% Javanese chili. The results obtained in this study were that all tobacco-based botanical pesticide treatments could reduce the whitefly population by 100%. No composition is most effective in suppressing whitefly populations on tomato plants.
