UB Forest is one example of forest ecosystems that are closely related to carbon cycle. However, the change of use of forest land into agricultural land in the forest can cause a negative impact on the environment, including reduced carbon reserves and decrease soil fertility, indicated by the reduced population of microbial activity and soil macrofauna. This study was aimed to explore effects of lang use change on microbial biomass and bacteria and bacterial population in the UB forest. The observation plot was determined based on land use, i.e., MK (mahogany 40 years and coffee 2-4 years), PK1 (pine 20 years and coffee 4-6 years), PK2 (pine 30 years and coffee 2- 4 years), PS (pine 40 years and cabbage), PM (pine 20 years and shrubs), MT (mahoni 40 years and taro), PK4 (pine 40 years and coffee 3-5 years) PK3 (pine 35 years and coffee 5-8 years). Observations were repeated 3 times, resulting in 24 plots. The extent of land area observed was 20 m x 20 m, including there was litter trap of 1 m x 3 m for observation of litter input dynamics. Vegetation observations and analyzes included in-situ litter weight, dry weight of litter per two weeks, dry weight of understorey, and polyphenol and lignin contents. Soil sampling was collected for analyses of C-organic, pH, microbial biomass, and total population of bacteria. The results showed that the highest values of microbial biomass carbon and total population of bacteria was found on PK3 land. The high microbial biomass carbon of 55,48 mg / kg-1 and total population of bacteria of 10.1 x 10-6 cfu/ml-1 had positive correlation and are influenced by litter input, understorey, C-organic content, soil pH, and litter quality in the form of polyphenols and lignin.

UB Forest has been converted into various uses such as agriculture and settlement. Land use conversion has an impact on decreasing soil organic matter, water quality, chemical properties and diversity of soil biota. Phosphorus is an essential nutrient for plants. But, its availability is very low, it is only 0.01% of the total P, because it is bound by the soil colloids. The aim of this study was to explore the difference of land uses and effect of enviroment to the diversity and population of phosphate solubilizing bacteria in the UB Forest. This study was conducted at various land uses i.e., protected area (KL), pine and coffee (PK), pine and annual crop (PS), mahogany and coffee (MK), and mahogany and annual crop (MS). Differences in land use significantly affected the population of phosphate solubilizing bacteria. The highest population of phosphate solubilizing bacteria was found in the plot of protected area (KL) of 103 x 106 cfu mL-1 and the lowest (7 x 106 cfu mL-1) was in the plot of pine and annual crop (PS).There were 11 bacterial isolates capable of dissolving phosphate sources in Pikovskaya media that were characterized by holozone with a ratio of 2.00 and 1.78. The suitable environment and sufficient substract can increase population of phosphate solubilizing bacteria.

There are many material of lime with different shape and size. The purpose of this study was to analyze calcium source with the right doses that can increase pH, provide nutrient available and decrease any toxic elements. This study used a completely randomized design with 18 treatments. The treatment included D0, C0, T0 (control), dolomite with 1, 2, 3, 4 and 5 t ha-1 doses (D1, D2, D3, D4, D5), Granular Calcite with doses of 100, 200, 300, 400, and 500 kg ha-1 (C1, C2, C3, C4, C5) and Suspension of Calcite with doses of 75, 100, 125, 150, 175 L ha-1 (T1, T2, T3, T4, T5). The results showed that application of calcium sources had significant effect on soil pH, Al saturation, Fe available, exchangeable-Ca, exchangeable-Mg, CEC, Base Saturation, available-P, total-N, and exchangeable-K in several time of observations. Application of 5 t dolomite ha-1 increased soil pH, and decreased Al saturation and available-Fe, and it also increased Ca and Mg contents. However, application of dolomite had no significant effects on N, available-P and exchangeable-K at several time of observations. The initial growth parameter was not significantly affected by application of dolomite.

Coffee plants belong to important commodities in Indonesia. In 2003, coffee productivity in Indonesia reached 725 kg ha-1 and decreased 0.41% in 2016 to 722 kg ha-1. Climate change is expected on the production of coffee crops. Some possibilities to reduce the effect of climate change are mitigation by implementing shade plants. This study aimed to understand the influence of differences shade on coffee plants toward infiltration and water storage in the soil. This study used a randomized block design that consisted of three treatments and five replications. The parameters observed were infiltration and water content in the soil conducted in three periods as well as the bulk density, particle density, porosity, macro pore, texture and structure. The results showed that the differences of shade on coffee plants gave a significant effect (p<0.5) toward infiltration of water. The highest total of infiltration was found in coffee plant with sengon shade (309.968 Â± 5.855 mm) from total rainfall of 354.731 mm. The results of water storage observation showed that the differences of shade in coffee plants had no significant effect (p>0.05) toward the amount of water storage in the soil. The value of water storage in the soil continued to decrease. The highest value in the coffee plant with durian shade was (287.0 Â± 15.086 mm) in the first week and the lowest value was found in the coffee plant with sengon shade (239.4 Â± 10.871 mm) in fifth week.

Forest plays important roles including, ecology, social and economic, for the sustainability of life. UB Forest, as an example, is located at the foot slope of Mt. Arjuna. This study aimed at elucidating exploring soil chemical properties of the UB forest. Five different land uses i.e., protected areas (KL), pine + coffee (PK), pine + annual crop (PS), mahogany + coffee (MK), and mahogany + annual crop (MS) were selected for this study. Each land use was repeated three times. Inside of each plot (20 x 20 m2 size), three sub-plots (5 x 5 m2 size) were prepared randomly for soil and litter sampling. Soil samples were taken from every sub plot, at four different depths (0-10, 10-30, 30-50, 50-100 cm), and then composited for the respective depth. Soil chemical properties (CEC, pH, total N, available P, C, available bases, soil texture, and litter (thickness, dry weight) were measured. The results showed that land uses in UB Forest significant affected total N, and pH, but theyÂ did not affect available P and CEC. The highest CEC was in KL. However, MS and MK tended to have high total, especially in the depth of 50-100cm.
