Cocoa is one of the mainstay commodities of Malang Region, which is sensitive to climate change. This research aimed to simulate climate change and its impact on water availability for cocoa plants in Donomulyo, Dampit, and Kromengan of Malang Regency using a simulated water balance method with climate change scenarios based on predictions from Indonesia Meteorological, Climatological, and Geophysical Agency (BMKG) and Intergovernmental Panel on Climate Change (IPCC). The climate change scenario consisted of an increase in air temperature of 0.5, 0.7, and 1°C, combined with changes in rainfall -5, -10, and -20%. Climate change impacted the air temperature increase at the earth’s surface followed by rainfall pattern changing, thus affecting the agricultural sector related to water needed increase and water availability decreased for plants. The results showed that along with the increase in temperature and decrease in rainfall, the water demand increased by 1.08-2.31%. The water availability in the soil decreased, followed by an increase in production reduction. The reduction in cocoa production occurred in each scenario with the highest percentage in scenario C9 (ΔT1⸰C, ΔH-20%). Production reduction results from not meeting the water needs of cocoa plants because it has a value greater than the ability to store water in the soil that occurs in several phases of cocoa plant growth, especially during the dry month period.

Coffee is one of the farm commodities which is a source of national income and foreign exchange for Indonesia. One of the successes in the production of coffee plants is climatic conditions because it has an important role related to the water needs of plants. The availability of soil water is closely related to the ability of the soil to hold water in the soil pores (pF) and provide water for plants. Efforts to reduce the impact of climate change are the use of shade plants which will produce many litters which affect the input of water in the soil to improve soil structure and pore distribution, which will affect the soil water holding capacity. This research was conducted from March to September 2020. The research was conducted in five fields based on differences in shade plants, namely in Sumbermanjing Wetan District, Malang. The results of this research indicate that the highest soil water holding capacity is in the PK land (cocoa shade coffee garden) both at a depth of 0-20 cm and 20-40 cm because PK land has denser shade plants so that it affects the amount of water available.

One of the damages that can occur in the soil structure is a decrease in aggregate stability. This study aimed to analyze the relationship between the stability of soil aggregates on a land by considering the level or type of land cover and the influence of several physical properties of the soil on coffee grounds. In this study there were four treatments with five replicates using a randomized block design at 2 depths, namely 0-20 cm deep and 20-40 cm deep. The treatments were based on different types of shade plants, namely P1 (cocoa shade), P2 (sengon shade), P3 (lantoro shade), and P4 (gamal shade). The results showed that lowest and highest soil aggregate stability values at the top depth (0-20 cm) were found in treatment P1 (cocoa shade) of 1.76 mm and P4 (gamal shade) of 3.33 mm. While at the depth of 20-40 cm, the highest and lowest values were found in the treatment P3 (lamtoro shade) of 1.92 mm and P1 (cocoa shade) of 2.37 mm. The stability of soil aggregates significantly affected soil bulk density, specific gravity, porosity, and organic matter. All treatments gave a significant effect on the thickness of the litter. The highest and lowest values were found in the treatment P4 (shade gamal) and P2 (shade sengon) of 3.4 cm and 1.7 cm, respectively.

Water and nutrients is important for plant which has its characteristics. This study has been carried out in the UB (Brawijaya University) forest about soil moisture content during rainy and dry seasons, Total-N, -P, -K from litter on different types of shade and age of coffee plants, and their effect on soil Available-N, -P, and -K. There are P1 (control), P2 (4-year-coffee + pine), P3 (7-year-coffee + pine), P4 (4-year-coffee + mahogany), and P5 (7-year-coffee + mahogany). These treatments affected to total soil moisture storage, Total-N, -P, -K of litter, and Available-N, -P, -K in the soil. The soil moisture storage change between rainy and dry seasons was 36.97 mm. The highest Total-N, -P, and -K of litter was 11.00 kg ha-1 y-1 at P3, 1.06 kg ha-1 y-1 at P2, and 4.35 kg ha-1 y-1 at P3, which was inconsistently associated with high soil nutrients. The highest Total-N was 0.40 (0-20 cm), 0.27 (20-40 cm), 0.30% (40-60 cm) at P4, Available-K was 1.69 (0-20 cm), 1.64 (20-40 cm), 1.87 cmol kg-1 (40-60 cm) at P5, and Available-P was 15.21 (0-20 cm), 14.06 (20-40 cm), 12.64 mg kg-1 (40-60 cm) at P1.

Human activities and global warming cause forest fires that impact increasing carbon emissions, destroy forest biodiversity and destroy soil properties. This research is needed to examine carbon storage and soil physical properties on various types of land cover in the Cempaka Forest area, which will later be used as a basis for carrying out restoration and conservation actions. This study used four observation points: Timber Forest Products, Non-Timber Forest Products, Pine, and Shrubs land cover. Carbon storage was measured in the Cempaka forest using the standard RaCSA procedure. The results showed that land cover differences significantly affect the value of carbon storage, with the highest value for storing carbon being the land cover of HHK. However, the difference in land cover did not cause different results on the physical properties of the soil. Correlation and simple regression between the value of carbon storage and other parameters show that carbon storage is strongly influenced by tree biomass and litter, with respective values of 94% and 21%.

Application of balanced fertilizers and the use of decomposers on land can improve soil health and nutrient availability for plants. Giving recommended doses of fertilization through the use of multispectral camera images lead to more efficient fertilization. This study aims to analyze the impact of the application of decomposers on the implementation of a multispectral camera image-based fertilizer recommendation system on soil physical properties, growth, and crop yield. This research was carried out from November 2021 to April 2022 at the experimental field in Sukamandijaya Village, Ciasem District, Subang Regency, West Java. This study was carried out with 2 treatments, namely land without the decomposers (P1) and with the decomposers treatment (P2) on rice fields of the Mekongga variety. The decomposer used was Petro Gladiator with dose 5 liters/ha (480 ml/plot or 56 ml/m²). Data analysis was carried out by unpaired T test at 5% level to determine the effect of decomposer application on soil physical properties as well as growth and crop yield. The results showed that the application of decomposers to fertilizer recommendation systems based on multispectral camera images can improve soil conditions including improvements in soil bulk density, soil particle density, total pore space, soil moisture content pF 1, 2, and 4.2, available pore water, then soil pH, available-P soil contents, potential-K soil content, as well as rice plant height.

Brassica sp. is a horticultural crop with high demand for consumption. To meet the demand, farmers apply intensive farming to increase yields and prevent plant pests and diseases that cause yield loss. Agrochemical applications in the form of inorganic fertilizers and pesticides contribute to lead (Pb) contamination in agricultural soils and increase lead (Pb) content in the cultivated plants. Nowadays, using bacteria for remediation (bioremediation) is environmentally friendly and effective in cleaning pollutants by converting organic Pb into inorganic Pb which is less toxic. This study aims to explore Pb-resistant bacteria that can reduce Pb-accumulation on food crops such as Brassica sp. grown in Pb-contaminated soil. This study isolated 15 isolates that survived on nutrient agar containing 1,000 mg/L Pb(NO3)2. The study showed 2 potential Pb-resistant bacteria that reduced Pb accumulation in Brassica sp. up to 30.5%. The bacteria are gram-positive bacilli and non-human pathogens (PT-3 and PT-5). DNA barcode identification results showed the isolates identified as Bacillus altitudinis (PT-3) and Bacillus wiedmannii (PT-5). Aplication of the bacteria increases the shoot length and fresh weight of Brassica sp. Application of the bacteria improves food crops quality by reducing heavy metals accumulation, such as Pb. Thus, the bacteria are potential as biofertilizers for reducing agrochemicals use in intensive agriculture areas and preventing environmental destruction and food contamination.
