Some flowering plants like common zinnia (Zinnia elegans (Jacq) Kuntze), marigold (Tagetes erecta Linnaeus), and cockscomb flowers (Celosia sp.) have been used as refugia and conservation plants for predators and parasitoids but are still not yet optimal. Planting refugia plants can affect insect diversity and evenness index, affecting the stability and balance of the agroecosystem. The study aimed to determine the effect of common zinnia, cockscomb flowers, and marigold as refugia on insectsâ€™ diversity and evenness index and their potential as a medium for conservation of predators and parasitoids. The study was conducted in organic rice fields in Batang Anai Sub-district, Padang Pariaman District, West Sumatra, from May to July 2020. The Insect was collected from plots covering an area of ??48 m2 and identified in the Bioecology laboratory, Faculty of Agriculture, Universitas Andalas. Planting common zinnia, marigolds, and cockscomb flowers increased the index of diversity and evenness of insects around rice fields. The index of diversity and evenness of insects on cockscomb flowers (H = 2.90) was higher than that of common zinnia (H = 2.61) and marigold (H = 2.63). Cockscomb flowers have more potential as a medium for conserving predators and parasitoids.

Forecasting of brown planthopper attack or BPH (Nilaparvata lugens Stal) using artificial intelligence and vegetation index of Sentinel-2 Satellite Imagery improves forecasting the incidence of hopperburn. This study aimed to determine the accuracy and correlation of the random forest classification of Sentinel-2 imagery to the incidence of hopperburn reported by Plant Pest Organisms Observer (PPOO) and determine the best method for predicting it. The study was done through observation and secondary data processing about the age of the plant, the incidence of hopperburn by BPH, interviews with farmers, and PPOO. The results showed that the hopperburn NDVI index ranged from 0.23 - 3.8. The random forest classification accuracy was high (Kappa Index = 0.82). The relationship between the hopperburn area from the PPOO report and the predicted area from Sentinel-2 images classified as (R2 = 0.53, R = 0.728) with the equation Y = -1.5 + 0.82 X. The correlation can be improved using spatial regression Geographically Weighted Regression (GWR4) with the best gaussian distance of 1.76 km (R2 = 0.6, R = 0.77). The best prediction for the NDVI stage of hopperburn attack time series with random forest (RMSE = 0.12819) was better than the prediction of the hopperburn attack time series with the exponential smoothing method from the PPOO report (RMSE 3.302184).

Biological control using parasitoids should be carried out to reduce the population of Brontispa longissima without pesticides. Tetrastichus brontispae is a larva-pupa parasitoid and is a gregarious parasitoid. Many factors can influence the biology of the parasitoid, which consists of biotic and abiotic factors. The existence of a host is one of the biotic factors that influence the life of parasitoids. The aim of the study was to study various biological parameters of the T. brontispae parasitoid which included the shape, size, color and length of each egg, larva, pupa, and imago stages as well as personality, sex ratio and number of hosts parasitized by female T. brontispae imago. The research was carried out in the form of an experiment using a completely randomized design. Experiments for biological observations of female T. brontispae parasitoids consisted of 4 treatments and 10 replications. The period of development, offspring, and sex ratio of the parasitoid Tetrastichus brontispae were studied using young pupa Brontispa longissima as hosts. Maintenance is carried out by inserting the parasitized larvae or pupa into the test tube provided. T. brontispae is a gregarious endoparasitoid. The development period from egg to imago is 18.95 ± 0.75 days. The length of life of the imago was significantly different between females (9.7 ± 0.51 days) and males (4.5 ± 0.52 days)—honey in increasing lifespan and enhancing T. brontispae offspring. The offspring of a female is 17.50 ± 1.08, with a female proportion of 60.12%. Imago T. brontispae fed honey had a longer and higher actual life span than without honey. Apart from the honey feed, the presence of a host can also affect T. brontispae.

The process of physical and chemical properties of the former gold mining soil which is caused by the transformation of different land conditions in natural rice fields, reclaimed rice fields, and mine fields. This study aims to determine the differences in the characteristics of the former gold mining soil in natural rice fields, reclaimed rice fields and mining fields in Sijunjung Regency. There were three sampling locations with three sample points each and the samples were analyzed physically and chemically. Results of this study showed that natural paddy soil has optimal conditions for the growth of rice plants followed by reclaimed lowland soil and the worst was in mining paddy soil based on soil physical and chemical properties. The difference in soil physical properties in the form of natural paddy soil texture was smoother compared to land conditions in reclaimed rice fields and mining rice fields. This was due to intensive inundation processes, which created a plough tread layer, low volume weight accompanied by a moderate total pore space. The difference in chemical properties was in the stable pH of natural paddy soil due to inundation and high organic carbon accompanied by rice reclamation and very low organic carbon in mining soils, which would affect the growth of rice plant.
