Abstract

Mapping of Land Drought in El Nino Phenomenon 2002, 2009 and 2015 in Bali Province Using Remote Sensing Technology and Geographical Information System Land dryness caused by the El Nino phenomenon in an area has a major impact on land productivity. The objectives of this study are (1) to compare the level of land dryness based on the El Nino phenomenon in 2002, 2009 and 2015, and (2) to determine the impact of El Nino on food crop production in Bali Province. To achieve this goal, this study uses Terra MODIS images. Drought condition is evaluated using vegetation greenness and air temperature parameters. Normalized Difference Vegetation Index (NDVI) and Vegetation Condition Index (VCI) are used to predict the vegetation greenness, where as Land Surface Temperature (LST) and Temperature Condition Index (TCI) are utilized to estimate the air temperature. Finally, Vegetation Healthy Index (VHI) is calculated based on value of VCI and TCI. The results shows that the El Nino phenomena in 2002 is the strongest dryness in Bali Province followed by the El Nino in 2015 and 2009. Most of the drought is spread over coastal area of Bali Province. There is the time lag around 6 months between decreasing of rainfall and appearance of drought symptoms. The total production of food crops in 2015 is the lowest, namely 1,032,067 tons, compared with production in 2002 and 2009 that is 1,127,452 tons and 1,252,443 tons respectively. However, statistically El Nino phenomena has no significant effect on food crop production. This is caused by the rice field irrigation sistem in Bali Province is still well maintained and the ability of farmers to mitigate the impact of drough on agriculture production.

Abstract

Effectiveness of Differences in the Planting Media Composition and Corm Size in Bali Local Banana (Musa paradisiaca var. Milk) Propagation Banana (Musa paradisiaca) is one of the important commodities in Indonesia. Based on BPS Prov data. Bali (2017), the number of productive banana plants in Bali has decreased enormously, from 13,140,965 clumps in 2016 to only 4,681,879 clumps alone in 2017. The need for banana supply is so high when balinese people celebrate Galungan and Kuningan Ceremony. Banana needs that occur cannot be met because the production in Bali is low, not filled with production because of difficulty in obtaining seedlings, for that it is necessary to do research on the composition of planting media and the right size of banana chopped corm to provide good banana seeds. The growth and development of good banana plant seeds cannot be separated from the use of good planting media and the use of quality seeds. This study aimed to find out the interaction of planting media composition and the size of chopped corm in local Balinese susu bananas. This research was conducted at the experimental garden paranet house of the Faculty of Agriculture, Udayana University, Jl. Pulau Moyo No. 15 X, Pedungan, South Denpasar, Denpasar City, Bali from April to July 2020. The design used in this study is RandomIzed Block Design (RBD) Factorial pattern with 2 treatment factors, the first factor was the composition of planting media consists of 4 levels of treatment namely M1 (mixed media of soil and compost (1:1/V:V) 100% + burn husk 0%), M2 (mixed media of soil and compost (1:1/V:V) 75% + burn husk 25 %), M3 (mixed soil and compost media (1:1/V:V) 50% + 50% burn husks), M4 (mixed soil and compost media (1:1/V:V) 25% + burn husks 75%), M5 (mixed soil and compost media (1:1/V:V) 0% + 100% burn husks). The second factor was the size of the weevil hemisphere, consisting of 3 levels of treatment, namely B1 (size of corm hemisphere 4 x 4 x 4 cm), B2 (6 x 6 x 6 cm) and B3 (8 x 8 x 8 cm). The results showed that M3 media (mixed soil and compost media (1:1/V:V) 50% + 50% burn husks) was the composition of the planting media was best, the M3 treatment produces leaf chlorophyll, plant height, number of leaves, diameter of stems, time of root appear and the time the bud appears. B3 (8 x 8 x 8 cm) was the best size of banana weevil, B3 treatment produces leaf chlorine, plant height, number of leaves, stem diameter, root time and the best leaf appear time. There was an interaction between the combination of planting media (M) and the size factor of weevil (B) to the growth of susu banana seedlings, which is indicated by the time the bud appears, the time the root appears, the diameter of the stem, the height of the plant and the number of leaves. The best value was obtained on the M3B3 combination.
