This study aims to evaluate the distribution of phosphorus (P) fractions within the soil horizons or profile of forest, agroforestry, and dryland in West Java and their correlations with soil chemical properties. Evaluation was based on the analytical results of soil samples taken from four soil horizons (Ao or Ap, A1 or A2, B1, and, B2) in each land use types. Fractionation of soil P was carried out using a sequential extraction method to get readily available-P (NaHCO3-P-inorganic (i)-P-organic (o)), rather available-P (NaOH-Pi-Po), slowly available-P (HCl-Pi), not available-P (residual-P), and total-P (HCl25%-P) fractions. The results showed that the average concentration of soil residual-P fraction in all land use types reached >99% of the total-P. The highest average concentration of residual-P fraction was measured in dryland, followed by forest and agroforestry. This indicated that soil P adsorption capacity was very high and resulted in a very low concentrations of the soil available-P fractions. The high concentrations of soil residual-P and total-P fractions were most probably related to P fertilizer application, particularly in dryland soil. Distributions of P fractions within the soil horizons at all land use types were significantly correlated with the concentration of soil organic matter content. It is therefore the concentration of soil NaOH-Po fraction was decreasing with the soil depths. The highest concentration was found at Ao or Ap horizon, although it was not the case for NaOH-Po fractions that was relatively constant.

Post-harvest handling of rice, especially in the rainy season, often experiences problems due to changes in weather, so that it takes a long time. In addition, conventional drying by drying using sunlight often causes the grain to become wet, moist, and some even grow. This causes the rice to break during milling so that it does not meet the quality standards of rice and the price decreases. If this process is disrupted, the level of stability of rice productivity and the supply of rice to the community will be delayed, which in turn will disrupt food security. A rice dryer with UV (Ultra Violet) Dryer technology can be a solution that can be used during the rainy and dry seasons. This tool is a dryer building measuring 10 m x 21 m, 3 m high, with a tool capacity of 10 tons, polycarbonate roof, galvanized pipe frame, and cast floor. The method of implementing PTDM activities, is socialization activities, design, preparation of materials, labor, implementation of assembly, and construction. The result of the socialization activity, is the application of dryer technology, really helps farmers in post-harvest handling, especially in the rainy season. It is hoped that the existence of this UV Dryer rice dryer can help post-harvest handling of rice and become a model for the community

This study aims to determine the macronutrients status of Nitrogen (N), Phosphorus (P), and Potassium (K), and soil acidity (pH) in the use of forest land, agroforestry, and dryland agriculture. The study was conducted by taking soil samples at four soil horizons (Ao or Ap, A1 or A2, B1, and B2) in each land use. Soil analysis in the laboratory to determine the concentration of N, P, K, organic C, and soil pH. Data analysis was carried out descriptively. The results showed that the distribution of N, P, and K on forest land and agroforestry decreased based on the depth of the land horizon, while the dryland agriculture has fluctuated. On forest land the concentration of N = 0.20-1.11%, P = 5.81-6.62 ppm, and K = 0.19-1.52%. Agroforestry N = 0.06-0.22%, P = 3.66-4.70 ppm, and K = 0.11-0.78 ppm. Whereas in the dryland agriculture concentration, N = 0.18-0.51%, P = 5.61-6.68 ppm, and K = 0.11-0.37 ppm. Organic matter, the intensity of tillage plays an important role in the distribution pattern and concentration of N, P, and K in the soil. Agroforestry systems can be a solution to the stability of soil fertility.

The results showed that peanut plants in paddy fields/moorlands, scrub lands and dry land forests obtained marginal land suitability class (S3) with limiting factors for nutrient retention (f) and available nutrients (n) for paddy fields/fields and dryland forests. , while the limiting factors in bushland are rooting media (r), nutrient retention (f), and available nutrients (n). Land suitability class for maize, on marginally suitable paddy fields/moor (S3) with limiting factors for nutrient retention (f), available nutrients (n), for bushland and dry land forests are not suitable at this time (N1) with limiting factors available nutrients (n). Basically, the existing limiting factors can be improved by fertilizing and liming.

The aim of the research was to determine the chemical properties of the soil in the rice fields of the Semangga district. The research method used is survey method. This research was conducted in 3 villages in the Semangga district which had rice fields. Soil sampling was carried out in a composite manner by taking soil samples at a depth of 0-25 cm. Soil samples were analyzed at the Bogor Environmental Biotechnology Laboratory. Based on the analysis results obtained data on soil chemical properties pH, C-organic, and cation exchange capacity (CEC). Based on the research results, the pH value was obtained from neutral to acid. The neutral pH value was found at location A, which was 7.61, at location B, the pH value was 4.42, and at location C, the pH value was 4.75. C-organic from the results of research at 3 locations is classified as moderate to high. At location A the soil organic matter value was 1.19, at location B the soil organic C value was 6.30 and at C location the soil organic C value was 4.11. Cation exchange capacity (CEC) at the study site was classified as moderate to high. At location A it has a cation exchange capacity value of 21.46 cmol/kg, at location B it has a cation exchange capacity value of 30.00, and at location C it has a cation exchange capacity value of 29.12.

Soil plays an important role in agriculture, soil cannot be separated from soil fertility in order to obtain maximum results. Soil quality on soil fertility is determined by the interaction of a number of physical, chemical and biological soil properties. pH, c-organic, and Al are some of the quality factors of soil fertility. Evaluation of pH, c-organic, and Al content aims to find out the current conditions and what solutions must be made. The research method was carried out by taking disturbed soil samples on primary, secondary, residential, and grassland lands, then carried out soil laboratory analysis. The results showed that: actual and potential soil pH is highest on residential land. The actual pH is 7.61 and the potential is 6.75 and is classified as neutral. While the actual pH in secondary forest, primary forest, and grasslands, the soil pH ranges from 4.42-4.99 which is classified as acid and the potential pH is 3.81-4.19 and is classified as very acidic. Meanwhile, the Al+ content was relatively low for each land use, namely 1.81-5.76 cmol/kg.

Sagu merupakan salah satu tanaman pangan yang dijadikan sebagai komoditi unggulan dan makanan pokok terutama bagi masyarakat Orang Asli papua (OAP) di Kabupaten Merauke. Penyebaran sagu di daerah ini terdapat di 60 kampung lokal termasuk di Kampung Tambat. Seiring dengan permintaan pasar pengolahan sagu sudah dilakukan dengan semi mekanik, sehingga tidak hanya menghasilkan sagu basah namun sagu kering juga sudah diproduksi. Pelaksanaan pengabdian dilakukan pada bulan September - Oktober tahun 2023 bertempat di Kampung Tambat Distrik Tanah Miring Kabupaten Merauke. Tahapan pelaksanaan kegiatan dimulai dari survei lokasi, serta mencari informasi tentang masalah yang dihadapi oleh masyarakat lokal terhadap pengolahan sagu. Setelah informasi diperoleh, selanjutnya tim pelaksana kegiatan bersama dengan masyarakat dan aparat kampung menyepakati pelaksanaan kegiatan penyuluhan, pendampingan dan demosntrasi alat pengayak sagu guna menyelesaikan permsalahan-permasalahan yang ada terutama pengolahan sagu
