Abstract

The use of botanical pesticides from natural ingredients that can be utilized is the bintaro plant (Cerbera odollam Gaertn.). This research aims to determine the effectiveness of bintaro leaf extract with water and ethanol as a solvent in controlling the main pests on chili plants. This research was conducted using the Completely Randomized Design (CRD) method. The results of the research showed that the application of the botanical pesticide Bintaro leaves was able to reduce pest damage to chilies, the lowest intensity of leaf damage was seen in the PD treatment (5.99%), then the lowest percentage of fruit damage was observed in the KC treatment (11.37%) and the PC (14.94%). Apart from that, the application of the botanical pesticide Bintaro PA leaves produced the number of fruit (47,146 fruit/ha), the second largest after chemical control (49,923 fruit/ha).

Abstract

This research aims to determine pests in feed corn at several moisture levels in storage warehouses developed in Tirta Jaya Village, Bajuin District, Tanah Laut Regency and PT Arutmin Site Satui, Tanah Bumbu Regency. Sampling at two locations was carried out directly at the farmer's corn storage warehouse and PT Arutmin Site Satui, at the Tirta Jaya Village location 4 kg samples were taken and at the PT Arutmin Site Satui location 3 kg samples were taken, then each sample was weighed weighing 300g each with 3 repetitions, and stored for 1 month. The warehouse pest data obtained will be grouped based on water content, varieties and pests obtained in 1 table. Next, the number of warehouse pest populations is calculated, the population average is calculated, the damage intensity is calculated, the data is tabulated and analyzed descriptively. The observation results showed that the Bisi 2 variety had the highest population of warehouse pests and the intensity of damage with a population of 143 Doloessa viridis, Tribolium sp. 58 individuals, 242 larvae and 11 pupae, with the highest average damage intensity reaching 34.6%. Meanwhile, the warehouse pest population and intensity were the lowest in the RK 457 variety with a total population of Tribolium sp. 8 tails with damage intensity reaching 8%.

Abstract

Leaf fall disease is one of the main problems in rubber plant cultivation (Brazilian rubber tree) which can significantly reduce latex productivity. This study aims to observe the intensity of leaf fall disease attacks on rubber plants treated with organic fertilizer plus Trichoderma, Plant Growth Promoting Rhizobacteria (PGPR), and eco-enzymes. Observations were conducted three times in the rubber plantation owned by PT. Bridgestone Kalimantan Plantation (BSKP), using a visual assessment method for disease symptoms and calculating the percentage of infected leaves. The data obtained were analyzed descriptively and quantitatively to determine disease progression trends. The results showed that the application of organic fertilizer plus PGPR was able to suppress disease attacks by 74.50%. followed by other treatments: application of organic fertilizer plus Trichoderma, control plants without application, and organic fertilizer plus Trichoderma supplemented with eco-enzyme, with percentages of attack suppression of 68.97%, 68.83%, and 66.83%, respectively. Air humidity and daily rainfall factors showed a positive correlation with increasing attack intensity. These findings demonstrate the importance of environmentally friendly disease control strategies. This research is expected to form the basis for more effective and sustainable management of leaf fall disease.
