Coffee is a source of foreign exchange that plays an important role in the development of the plantation industry. However, many coffee-producing regions have experienced quite detrimental yields in recent years due to the rust of coffee leaves (Hemileia vastatrix), a parasitic fungus that reduces yields and that can ultimately kill coffee plants. The use of biochar enriched with Trichoderma can help to improve soil conditions and increase crop production because biochar can increase the availability of N and P. Trichoderma as a biocontrol agent that can help in solving the problem of coffee leaf rust. This study that was conducted at Gondorejo Village, Oro-oro Ombo sub-district, Batu District used a completely randomized design with seven treatments and four replications. The results showed that the application of media with a composition of 1% biochar enriched with Trichoderma supported the growth of Arabica coffee seedlings at the age of 3 months. It can be seen from the available N content, which showed an increase and the number of leaves which had the highest increase among other treatments. This indicated that the composition was sufficient to support good media for the growth of Arabica coffee seedlings.

Various efforts have been carried out by the Indonesian Government to increase rice production, especially the construction of new paddy fields and paddy intensification through increasing intensity or planting frequency in a year. Overcoming the problems of chemical and physical soil properties that have caused low soil productivity is an effort that can be made to increase rice production. This study was aimed to assess the quality of soil physical and chemical properties of the paddy fields in order to find out the cause of the low productivity of paddy soils. The study was conducted in 24 locations in Banten and West Java Provinces. In general, based on their soil quality indexes, the study found that the soil physical quality of paddy soil is good and better than soil chemical quality. There was no significantly different between soil physical quality of paddy soil in Banten and West Java Provinces. However, the soil chemical quality of paddy soils in West Java Province is significantly better than in Banten Province. There were no limiting factors for soil physical properties, while in some locations, some limiting factors of soil chemicals properties were found. Dominant limiting factors for plant growth were the low available P, organic matter and total organic N contents, low pH, and low exchangeable K, and high level of Fe.

The land use condition in Sumber Brantas Village, Batu City is 25.66% not compatible to the land capability class, while the land use condition based on the regional spatial plan there is an increase in land use by 32.05%. Land use conversion at Batu City in 2008 - 2015 reduced 748.06 ha of forest area in line with an increase in dryland area of 565.18 ha; and the increase of garden area by 329.84 ha. Transfer of land functions results in changes in land cover and causes a decrease in the potential of the actual forest function. A study related to the physical properties of the soil in Sumber Brantas Village is thus needed to obtain data on current soil conditions. This study was conducted to analyze the effect of differences in land cover and soil depth on aggregate stability and its correlation with other soil properties on the western slope of Mount Arjuna. Soil sampling was carried out on four types of land cover, i.e. horticulture, forest, shrub, and grassland at depths of 0-20 cm, 20-40 cm, and 40-60 cm with three replications for each treatment. The results showed that the type of land cover affected the soil aggregate stability, while the depth of the soil did not affect the soil aggregate stability. Organic matter influenced the value of aggregate stability with the R2 value of 0.87. Clay particles affected aggregate stability by 0.56. Aggregate stability affected soil porosity, soil macropores, and soil hydraulic conductivity with the R2 values of 0.76, 0.53, and 0.42, respectively.
