The purpose of this study was to develop data and information on potential locations to analyze the level of vulnerability to conversion of paddy fields in Prafi Mulia village. This research is a descriptive study with survey methods by using questionnaire and taking coordinates of paddy fields using the Avenza Maps application. The results found that there are three level of vulnerability to conversion of paddy fields, namely very vulnerable, vulnerable, and not vulnerable. After overlapping the maps, it was found that the land that is very vulnerable to land conversion is 59.5 ha from 13 farmer groups. The farmer group with the highest level of vulnerability is Harapan Makmur with an area of 14 ha and the lowest level of vulnerability is the Sidodadi Farmer Group with an area of 0.5 ha. There are 138 ha of land with the highest vulnerability category and the highest vulnerability is found on land belonging to the Karya Bakti farmer group, which is 16 ha and the lowest is the Rukun Tani, Sido Dadi, and Sumber hasil farmer groups with an area of 5 ha. In the non-prone category, there is an area of 81 ha with the highest value in the Tekat Maju farmer group of 21 ha and the lowest in the Karya Bakti, Sido Mukti, and Margo Mulyo farmer groups with an area of 1 ha.

The purpose of this study was to identify the area distribution of Sustainable Food Agricultural Land (LP2B) in Bowi Subur Village (SP6) Masni District. The methods used are spatial methods and field surveys. Observational variables in this study include data on paddy fields based on lowland rice cultivation techniques, lowland rice productivity results, irrigation facilities and farmer responses regarding lowland rice cultivation. The results of this study found that Bowi Subur Village in recent years experienced a decrease in productivity, which was only 0.69 to 1.1 tons/ha due to the acidic nature of the soil, and damaged irrigation networks that were still being renovated, so to meet the needs of life, farmers sold land. rice fields, and finally change the function of the land. There were 3 categories of land availability for LP2B in Bowi Subur Village, namely very eligible, eligible and inappropriate. Very eligible criteria for LP2B has an area of 14 ha, while Eligible criteria and unfeasible criteria for LP2B have area of 23.5 ha and 11 ha, respectively.

This study aimed to predict the need for lowland rice land, and evaluate the suitability of the land to meet food needs in the West Papua province. This study used a descriptive method with food demand projection techniques to predict the need for lowland rice land; and the technique of matching data on physical characteristics of land with land suitability criteria for lowland rice plants based on the Land Evaluation Technical Manual to evaluate the suitability of lowland rice fields. The projection result showed that the demand for food and land tends to increase every year, therefore, based on the comparison between food needs and the production, the West Papua province tends to experience a food deficit. An alternative to increase rice production is the extensification of paddy fields. The results of the evaluation of actual land suitability for lowland rice in the West Papua province ranged from the suitability class moderately suitable (S2) to marginally suitable (S3), with the limiting factor in the S2 land suitability class were nutrient retention (KB, CEC), available nutrients ( P2O5, N-total) and soil texture; while the limiting factors in the S3 land suitability class were slope, temperature and soil texture. If improvement efforts are made by adding organic matter and fertilization, then the distribution of potential land availability (available and suitable) is spread in very suitable land suitability classes (S1) and quite suitable (S2), with the largest land area being in Teluk Bintuni district.

Land degradation is the result of land use or utilization that exceeds the capacity of the land, which will cause critical land. The impacts that occur due to critical land include land degradation in the quality of soil properties, decreasing conservation and production functions, as well as affecting the social and economic life of the people who use the land. This study aimed to reduce the hazard of critical land, based on modeling changes in land cover/use using the Artificial Neural Network (ANN) method. The results of this study indicated that land classified as dangerous to become critical land includes sloping land with converted land cover/use. Reducing the risk of critical land hazard can be done by using land that is in accordance with the ability of the land, by following the rules of soil and water conservation, as well as the role of the government in conserving upstream areas that are oriented towards regional spatial patterns.
