Abstract

Hanif et al, 2017. Efficacy of Bacillus thuringiensis Barliner Bioinsecticide against  Gryllus bimaculatus De Geer (Orthoptera: Gryllidae) in Major Rice Crops and Ratooning Rice. JLSO 6(1):95-105. Crickets (Gryllus bimaculatus) are an important pests on rice that can reduce productivity. The application of Bacillus thuringiensis bioinsecticide is expected to be an alternative methode to control these pest. The objective of the study was to investigate optimal dose of B. thuringiensis in suppressing rice damage was caused by G. bimaculatus. The observation were conducted on rice cultivation in Pelabuhan Dalam Village, Pemulutan Subdistrict of Ogan Ilir Regency. The results showed that application of B. thuringiensis bioinsecticide had significant effects in suppressing rice crop damage by G. bimaculatus, but did not had significant effect on growth of rice plants.

Abstract

Prabawati et al, 2017. The Role of Wild Flowering Plants in Conserving Insect Natural Enemies in Lowland Oil-Palm Ecosystem of South Sumatera. JLSO 6(1):78-86.Wild flowering plants can be used in increasing the potential of insect natural enemies on oil palm plantations. This paper inventoried the diversity of natural enemies that interacted with wild flowering plants in the oil palm ecosystem. Wild flowering plants are used as feed sources and living places  which provide alternate hosts for natural enemies, namely predators and parasitoids. Some families of flowering plants associated with  parasitoids in oil palm ecosystem include Euphorbiaceae, Leguminosae, Fabaceae, Acanthaceae, Asteraceae, Polygonaceae, Rubiaceae, Capparidaceae, Lamiaceae, Turneraceae. Some plant species associated with predators in oil palm plantations include Antigonon leptosus, Elephantopus tomentosus, Nephrolepis biserata.

Abstract

Hanif et al, 2019. Population of Pest Insects and Predatory Arthropods Inhabiting Freshwater Swamp Rice of South Sumatra Treated with Bioinsectide of Beauveria bassiana and a Synthetic Insecticide. JLSO (8)1:31-38.Entomopathogenic fungi, Beauveria bassiana, could  kill various species of insect pests, but  their impact on predatory arthropods needs to be studied. The aim of this study was to compare population of pest insects and predatory arthropods inhabiting rice sprayed with bioinsecticide of B. bassiana and conventional rice field using a synthetic insecticides. Bioinsecticide was made from conidia of B. bassiana and sprayed on rice canopy. The plot of conventional farmers was sprayed with synthetic insecticides made from Abamektrin. The results showed that the application of bioinsecticide of B. bassiana was not proven to reduce the pest insect population. The abundance of natural enemies of pest insects, such as  spiders and predatory insects was also more abundant in plots sprayed with  bioinsecticide than conventional plots that used synthetic insecticide. The synthetic insecticides have been shown to reduce the abundance of predatory insects and spiders. Bioinsecticides containing carrier of  liquid compost were proven to increase the growth and development of rice, which was an increase in the number of rice tillers per clump in plots applied by bioinsecticide. Thus, B. bassiana of bioinsecticide with liquid compost carrier material was safer and could maintain the abundance of predatory arthropods and increased rice growth.

Abstract

Swampland is one of the agroecosystems that has not been optimally utilized, especially in agriculture. This land is included in sub obtimal land in South Sumatera province. This research aims to determine the feasibility of horticulture cultivation efforts with floating methods on swampland. The location of the research was the swampland in Srimulya Village, Sematang Borang District of Palembang City on inundated season from January to June. This study was conducted by combining interview methods and participatory observation with respondents. The method used in determining economic feasibility was business feasibility analysis using R/C and B/C Ratios. The types of data processed were primary data and secondary data with quantitative type. Based on the results, it can be concluded that floating cultivation system for kale can add family income to swampland. With the total cost of each harvest being Rp 4.390.000,00 , an acceptance of Rp 14.000.000,00 is obtained. The net income earned every harvest is Rp 9.610.000,00. The Revenue / Cost Ratio is 3.19 while Benefit / Cost Ratio is 2.19. It can be concluded that the floating cultivation system is feasible to be implemented on swampland.
