OPTIMIZATION OF LEISA SYSTEMS AND BIOREMEDIATION MODELS IN PITISIDE AND HEAVY METAL RESIDUES IN POTATO CULTURE (Solanum Tuberosum L)

Optimization of the LEISA system and the development of an in-situ bioremediation model are primarily aimed at making healthy agricultural land cultivated with varieties of granola varieties G0, G1 and G2. The impact of healthy land is (1) tubers not indicated to contain pesticide residues and heavy metals, (2) seed potato tubers (weight less than 10 g) less than 20%, (3) medium class potato tubers (weight 10 - 30 g ) more than 40%, (4) large grade tubers (31-60 g weight) of 30-40% and tubers not suitable for seedlings (weighing more than 60 g) less than 5%, and (5) potato seed production targets broad union of around 15 tons / ha.
The scope of the study are (1) identification of pesticide and heavy metal contamination in the land cultivated by seed potatoes, (2) active microbial reliability testing on compost to carry out the bioremediation process of pesticide residues and heavy metals in-situ, (3) optimization of the use dose effective compost supporting bioremediation processes in-situ; (4) developing in situ bioremediation processes on pesticide-contaminated land; and (5) optimization of productivity and quality of seed potatoes produced.
In 2018 the research was (1) finding the level of pesticide contamination in cultivated potato seed land, and (2) finding the type of bacteria that was most active in carrying out the bioremidiation process in-situ through incubation, dilution, inoculation, isolation, identification, reliability degradation testing pesticide residues, and bacterial activity tests. Microbial reliability testing in the bioremediation process in a laboratory will produce output types and compost doses that effectively support the bioremediation process of pesticide residues.
Research activities in 2019 will focus on optimizing the LEISA system and developing a bioremediation model for in-situ pesticide-contaminated land. This year's research activities include: (1) optimization of doses and types of compost used as organic fertilizer and reliability testing of pesticide-contaminated land bioremediation processes in a controlled environment (greenhouse), and (2) reliability testing of bioremediation processes of pesticide-contaminated land in-situ on open land. The second year research output is optimal in-situ bioremediation process, the bioremediation process is measured by the level of pesticide contamination after the process.
Research activities on optimizing the productivity and quality of the resulting potatoes carried out in 2020 are the activities of implementing the bioremediation process in-situ. Manipulation of the environmental conditions of the bioremediation process (water content, soil media and soil pH in the root zone) is done to achieve productivity and quality of seed potato output, because in potato cultivation there are two different seasons.
