Abstract

The Mucuna bracteata plant breeding training aims to improve students knowledge and skills in vegetative and generative plant propagation. Plant breeding is a combination of art, science and technology in assembling the genetic diversity of a particular plant population to be better or superior than before. Community service activities were carried out on Thursday, May 15, 2025 using socialization and training methods. This activity involved the active participation of participants in all stages of the process. This training covers the topic of vegetative and generative plant propagation. The training showed positive results where participants were able to understand how to select cuttings and prepare mucuna seeds and plant the cuttings and mucuna seeds in the planting medium. Keywords: mucuna, plant breeding, plant propagation

Abstract

The rhinoceros beetle ( Oryctes rhinoceros L.) is one of the main pests in oil palm plants that can cause serious damage, especially in the Immature Plant (IMPACT) phase. This pest attack causes damage to the growing point, thus inhibiting vegetative growth, reducing plant vigor, and potentially delaying the plant entering the productive phase. One of the control efforts commonly applied in oil palm plantations is the use of insecticides containing the active ingredient cypermethrin. This study aims to evaluate the effectiveness of cypermethrin application in reducing the intensity of O. rhinoceros attacks on IMPACT phase oil palm plants at PTPN IV Regional 1 Rantauprapat Plantation. The study was conducted in January–February 2026 using a field observation method with a quantitative approach and a paired observation design . A total of 114 sample plants from Blocks N07, N09, and O07 were observed before and after cypermethrin application at a dose of 1.6 cc per plant. Data were analyzed descriptively and tested using a Paired Sample t-test at a significance level of 5%. The results showed that the average attack intensity decreased from 78.07% before application to 20.18% after application, with a control efficiency of 74.15%. The results of statistical tests showed that cypermethrin application had a significant effect on reducing the intensity of O. rhinoceros attacks ( p < 0.05). Thus, cypermethrin is effective as a control measure against active attacks of O. rhinoceros on oil palm plants in the TBM phase. However, its use still needs to be combined with the implementation of Integrated Pest Management (IPM) to increase control effectiveness and reduce the risk of insecticide resistance.

Abstract

Rice (Oryza sativa L.) is a strategic food commodity and a primary source of carbohydrates for most of the world's population, including Indonesia. One effort to increase rice production is through mutation.The purpose of this study is to study the influencegamma ray irradiation on several rice varieties at the germination seedling phase. Gamma ray irradiation was carried out in January 2025 at the Center for Isotope and Radiation Applications (PAIR), National Nuclear Energy Agency (BATAN), Pasar Jumat, Jakarta, while planting was carried out on Jl. Belibis, Rantau Selatan District, Labuhanbatu Regency in March 2025. The study used a non-factorial Completely Randomized Design (CRD) namely gamma ray irradiation at the following doses: 0 Gy (control/no radiation dose); 50 Gy; 100 Gy; 150 Gy; 200 Gy; 250 Gy; 300 Gy; 350 Gy; 400 Gy and 450 Gy.Observations were made on germination rate, seedling height, and root length. The data were analyzed using analysis of variance followed by Duncan's multiple range test (DMRT). The results showed a visible effect of gamma ray irradiation on germination rate. Gamma ray irradiation also affected average seedling height and root length.The lowest reduction in germination and seedling height occurred in the Sibenang rice variety at a dose of 450 Gy, at 0%. Meanwhile, the shortest root length was in the Ciherang rice variety at a dose of 450 Gy, at 1.93 cm.

Abstract

Mucuna bracteata is a type of legume commonly used as a ground cover plant in oil palm plantations. This plant is useful for reducing weeds, increasing soil fertility, and improving soil structure through nitrogen fixation. However, Mucuna bracteata seeds have a very hard, impermeable shell, which prevents water from entering the embryo and slows down the germination process. The purpose of this study was to examine how mechanical scarification of seeds can improve their germination capacity. Mechanical scarification was carried out by damaging the tip of the seed until the white flesh was visible. Observations were made for 4 weeks after planting and included the percentage of germination, plant vine length, and number of leaves. The results showed that scarification accelerated and increased the seed germination rate by 30%. However, its effectiveness in breaking the dormancy of all seeds was still low, so additional methods or combinations of other treatments are needed to achieve higher germination rates. Keywords: Mucuna Bracteata, Mechanical Scarification, Germination
