Abstract

Astuti et al, 2018. Utilization of Organic Waste in the Making of Bacillus thuringiensis-based Bioinsecticides as Agents for Control of Caisim Brassica juncea Pests. JLSO 7(2):136-143. Bacillus thuringiensis was one of the entomopathogenic bacteria that can produces toxic crystal proteine (ᴕ-endotoksin). The use of bioinsecticide as a biological agent in pest control was one component of integrated pest control (IPM). The aimed of this reseacrh was to know the population of pests in plants and the percentage of damage to plants that exist in each treatment. The research was conducted in a vegetable garden in the Banyuasin district in November 2017 until January 2018. The research method used a randomized block design with 5 treatments and 4 blocks. The treatment was Bacillus thuringiensis KJ3R5 cultured in coconut water and rice washing water  (A), Bacillus thuringiensis LC2 cultured in coconut water and tofu wastewater (B), commercial Bacillus thuringiensis (C), inorganic insecticide (sidametrin) (D), and water as control (E). The variables observed were arthropod populations on the canopy and ground surface of choy sum (Brassica rapa var. parachinensis or Brassica chinensis var. parachinensis) plants. The results showed that 4 species of pests i.e. Pyllotreta crucifera, Spodoptera litura, Plutella xylostella, and Helula sp. Treatment with Bacillus thuringiensis LC2 (B) resulted in reduction of plant damage by 61%.

Abstract

The dynamic nature of forest habitats is currently influenced by the impact of many disturbing factors, including fire, grazing, area fragmentation, land use conversion and invasion of communities outside forest areas. Fire and smoke from forest and land fires have a profound effect in producing landscape changes that also affect the regeneration of associated vegetation and animals. This study aims to determine the participation of the members of the beekeeper group in preserving the Subanjeriji production forest, in Muara Enim Regency, South Sumatra Province. The research was conducted using a survey method with a qualitative approach. This study also aims to determine the attitudes, knowledge and perceptions of beekeepers on the relationship between beekeeping and forest suistanibility. The results showed that beekeepers known the suistanibility of forest areas that affect the success of beekeeping (80%), so that 60% of beekeepers understand very well that forest and land fires can reduce bee populations and reduce the amount of honey bee. Most breekeepers also understand that the existence of forest plants is very beneficial to support honey production, so that the majority beekeepers are involved in land enrichment efforts with woody plants and most choose Multi Purpose Tree Species (MPTS) plants that produce fruit. Keywords: Participation, Beekeepers, Beekeeping, Sustainibility, HP Subanjeriji

Abstract

Organophosphate pesticides are one of the causes of contamination in animal feed. The cholinesterase enzyme test is used to diagnose toxic exposure due to organophosphate pesticides. Quantitative research with survey design using cross sectional design using 35 samples of cows. The study was conducted in March - September 2020. Concentration measurement on cholinesterase enzyme concentrations of blood plasma used the biosystem A15 DGKC-Colorimetric Kinetic method. This study aims to evaluate the concentration of the enzyme cholinesterase as a marker of organophosphate poisoning in cattle. Blood samples were collected from the ventrolateral neck veins of male and female cattle aged 1-7 years and collected from local cattle in the Ogan Ilir area. The results showed that the cows raised in breeders were exposed to organophosphate pesticides as indicated by a decrease in the concentration and levels of the cholinesterase enzyme in the plasma of female cows. Cholinestrase enzyme levels in female cows were 0.20 ± 0.067 U / ml and bulls were 0.27 ± 0.183 U / ml. The highest concentration of cholinesterase enzyme levels occurred in cows aged 2 years, namely 0.25 ± 0.34 U / ml and the lowest was in cows aged 7 years, namely 0.12 ± 0.04 U / ml.
