This study aims to calculate the total economic value of lowland rice farming in Bogor Regency, and identify the factors that influence land conversion from agricultural to non-agricultural uses. By using the productivity method approach, CVM and benefit transfer, it can be seen that the total economic value of lowland rice farming in Bogor Regency, West Java is Rp. 119,480,139 / hectare / year. The new economic value is calculated based on functions as a food producer, as a function of absorbing labor, as a function of food security stability, and as a function of flood mitigation, not yet included as a function of erosion and sedimentation mitigation, as a function of air conditioning and freshener, as a function of carbon retarding, as a function of recycling organic waste, as well as a function of social culture and rural appeal. Then by using descriptive statistical analysis and simple regression, it is known that the conversion of paddy farming land in Bogor Regency, is influenced by internal factors, external factors, and government policies. Internal factors include: the geographical location of agricultural land, the area of agricultural land owned by farmers, the amount of farmers’ income, transformation of farmers’ economic structure, and farmers’ understanding of multifunctional agriculture. External factors include: population growth, urbanization, the macroeconomic situation, the ability of agricultural land, the value of land (land prices), the opportunity to buy land elsewhere which is cheaper, and the influence of the private sector. Government policy is the factor that is considered to have the greatest influence on the occurrence of agricultural land conversion in Bogor Regency, especially the problem of the implementation of government policies relating to rules regarding conversion of agricultural land that have not been implemented optimally.

Land conservation in the upstream Ciliwung watershed is an effort to achieve sustainable development. Considering that land conservation is external, assistance from the government is needed to implement it, especially for farmers as conservation users of land resources. The purpose of this study is the influence of farmer behavior in land conservation and motivation about land conservation on farmers’ income in the Ciliwung Hulu watershed, Bogor Regency. This research is explanatory research with a descriptive method where data collection using survey techniques. This research was conducted in the Ciliwung watershed, namely Cisarua and Megamendung Districts, Bogor Regency. To find out the behavior and motivation of farmers in land conservation that affect the income level of farmers, it was identified using the Multiple Linear Regression analysis model with OLS (Ordinary Least Square) estimation. The results showed that the behavior and motivation of farmers in land conservation in the Upper Ciliwung watershed, Bogor Regency influenced efforts to increase farmers’ income. An alternative cropping pattern, it is recommended to plant leeks once in the rainy season accompanying rice and two times to plant mustard greens accompanying leeks in the dry season.

Setting the cropping pattern in the use of paddy fields is one of the important steps that determine the income, use, and distribution of farm labor. The study was conducted by utilizing secondary data production, cost analysis, etc. in the series 2009-2018 in Bogor Regency. The analysis uses linear programming by setting the raw area of paddy fields and paddy farmer labor as constraints and maximizing income as a goal. The use of agricultural land in the Bogor Regency continues to shrink every year. The optimal solution to the cropping pattern that is produced turns out to still leave land and labor resources, so an alternative cropping pattern is needed to utilize these resources. The recommended cropping pattern needs to be implemented through empowering farmer groups proportionally according to the area of land and labor they have.

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).

Land and Building Tax is one type of central tax, the collection and imposition of which is largely left to the Regional Government. Analysis of the Sales Value of Tax Objects (NJOP) on Land and Building Tax (PBB) Revenues, and Land and Building Acquisition Fees (BPHTB), to find out more efficient and effective ways in the matter of PBB and BPHTB revenue. Therefore, research on the increase in NJOP on PBB and BPHTB revenue is deemed necessary to obtain valid information as the basis for PBB and BPHTB revenue. This research was conducted in Cibinong Subdistrict, Bogor Regency, with a sample of 180 taxpayers in Ciriung, Cirimekar, and Pondok Rajek Villages which are included in the Cibinong District area. The results showed that the (NJOP) of the earth was strongly influenced by the location of the object and land use, and the NJOP of the building was strongly influenced by the type of building, the area of the building, the year it was built, the roof of the building and the floor, and the NJOP and the building were strongly influenced by the value of the earth per M2 land area, and building area. NJOP has an increasing effect on PBB and BPHTB.
