P fertilization and application of organic matter are some of the efforts to increase the P availability in the soil. The application of organic matter enriched with phosphate fertilizer increases the P-available in soil. This study therefore aims to determine the effect of applying organic matter enriched with phosphate fertilizer on several chemical properties as well as productivity of lowland rice fields in Bogor Regency. The study was conducted by UNB’s greenhouse and paddy fields in Darmaga, Kemang and Sukaraja Districts, Bogor Regency. Organic material in the form of cow dung with a dose of five levels was enriched with phosphate fertilizer in the form of H3PO4 in an equal dose, and incubated for 30 days. Subsequently, the phosphate enriched mixture with the best incubation result for fertility level was applied in the paddy fields. The results showed about 60 tons / ha of organic matter 225ppm P of Posfat fertilizer had optimum fertility after 30 days incubation, followed by 40 tons / ha of organic, enriched with the same dose of phosphate fertilizer. In addition, Latosol soil, Bogor Regency, where organic matter enriched with about 225ppm P of phosphate fertilizer in all locations had the same soil fertility and lowland rice productivity, meaning no significant difference was obtained using the same dosage of organic matter. Meanwhile, soil fertility in the form of pH, available CEC and P increased, as well as lowland rice productivity, increased with the application of organic matter (60 tons / ha).

In every region that is transitioning from agrarian economic activity to industrial economic activity, it is always faced with deforestation or changes in forest cover, including in West Nusa Tenggara. This study aims to determine the effect of economic growth and population on land cover change and deforestation in West Nusa Tenggara Province. The research was conducted in March -August 2020, which consisted of activities to determine land cover changes through processing satellite image data, which was matched with data from BPS. Data on economic growth and population are obtained from BPS. Modeling with multiple linear regression. The results of regression modeling show that economic growth and population growth significantly increase land for building and reduce forest land cover.

The economic growth rate is an indicator used to measure the achievement of development. In 2020, the economic growth rate of Banyumas Regency contracted by -1.65 percent but this figure is still above the economic growth rate of Central Java Province which is -2.65 percent. The economic growth of a region is driven by the leading sectors in the region. This research aims to find out the leading sectors in Banyumas Regency that experienced progressive, growing, sluggish and backward movement during the Covid-19 outbreak compared to Central Java Province using Location Quotient and Shift-Share (LQ Shift- Share) analysis.  The results of the analysis showed that the sectors that contributed the two largest to the Gross Regional Domestic Product (GRDP) in Banyumas Regency in 2020 at the same time including the progressive sector were trade sector (G) and construction sector(F).
