Abstract

Darmawan AR, Rani A, Hawari MH, Nurhaliza S, Zuhri S, Nainggolan YA, Pratama, W. 2022. Inventory of the koksi beetle on citrus plants in north Indralaya Village, Indralaya Mulia Village, and Pemulutan Village, Ogan Ilir Regency. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 489-494. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).In citrus plants, the koksi beetle acts as a natural enemy for pests, they will eat insects such as aphids, caterpillars, and other plant-destroying insects. This study aimed to inventory the species of koksi beetle in Indralaya Mulia Village, Pemulutan Village, North Indralaya Village, Ogan Ilir Regency. The method carried out in this observation uses a random survey method which is carried out by direct observation. The results showed that the koksi beetle in the first, second and third fields were different in each observation, the koksi beetle found on citrus plants, namely Coleomagilla macullata, Coccidulinae, Novius cardinalis, was found on the leaves and also on the young twigs, namely below the surface. leaves, the data used using primary data and secondary data. Secondary data were obtained from literature reference sources. While the primary data obtained from observations in the field. The data obtained will be presented in the form of a table. So the population of the koksi beetle in the three villages has different species, this is influenced by the presence of abiotic and biotic factors that are around the land. To find out more detailed data from the koksi beetle on citrus trees, an inventory of the koksi beetle can be used.

Abstract

Suboptimal land such as tidal swamps is still quite widespread in Indonesia and has a low fertility level. This land requires good management to support optimal crop production. One management that still has the potential to be developed is the use of microorganisms, namely AMF. Use of AMF in tidal soil in the form of AMF inoculant as a natural biofertilizer. The aim of the research is to evaluate the effectiveness of local tidal AMF propagules produced during trapping on corn host plants which will be used later as biofertilizer. This study used a factorial randomized complete group design (RKLT). The first factor is the dose of local AMF propagules from the corn host plant (0, 5 and 10 g plant-1) and the second factor is the fertilization interval (1 and 2 times a week), with 3 replications for each treatment unit consisting of 20 plants. The application of AMF propagules showed an effect on plant height, leaf green level, shoot dry weight and percentage of AMF infection. The level of greenness of corn plant leaves was highest when 5 g of AMF propagules were given when compared with 10 g of AMF propagules and without AMF propagules. The increase in the percentage of infection of corn roots by AMF at 10 g of AMF propagules+1 time a week when compared with no AMF propagules+1 time a week and 5 g of propagules+fertilization 2 times a week was 50.67% and 46.34%.
