Flood is a major disaster which often occurred in last decade. Generally, land management in upper watershed is the main driving factor that cause flood. Upper watershed area should be intended for catchment area, but in fact land use change from natural forest become agriculture practices continuously happened. This research was done in September-October 2008 in Sumber Brantas sub watershed, City of Batu and some part of Malang Regency. Spatial analysis and land maping was done in Geographic Information System Laboratory of Soil Science Department, Brawijaya University. The objective of this research was to estimate troubled area of flash flood distribution. The parameters were:river flow discharge, slope, distance from river & elevation. The predicted river flow discharge was compared to actual river flow discharge and stastistically tested using doubled regression. This was done to know the accuracy of the model. River flow debit assessment using 15 micro sub watersheds with Thiessen Fraction Distribution (TFD-micro watershed) treatment result the most accurate river flow debit compared to field measurement. River flow debit assessment using one watershed with Average Thiessen (AT-watershed) treatment result lower accurate compared to TFD-micro watershed. In AT-watershed treatment river flow debit result is slightly close to measurement, but there are a significant difference in July and August. The worst result of the validation is the method using 15 micro sub watersheds with Average Thiessen. This caused by rainfall distribution which was used as input data was inappropriate with micro sub watershed distribution in Sumber Brantas sub watershed area. Totally the troubled area of flash flood based on troubled river area of flash flood is as much as 202.23 ha. Troubled area of flash flood is located in 4 Sub Regency, they are: Batu sub- regency as much as 29.39 ha, Bumiaji sub-Regency as much as 164.43 ha, Junrejo sub-Regency as much as 6.08 ha and Pujon sub-Regency as much as 2.43 ha.

Tea plantations are mostly more suitable to be cultivated in areas with highland characteristics to get itsâ€™ subtropical climate which is great for the growth of tea. This requirement showed that tea plantations are also cultivated in areas with different ranges of slope and this condition could affect soil chemical properties such as soil nutrient content, including soil pH, soil organic carbon (SOC) and contents of N, Available P, K and Mg inside the soil. This study was conducted to analyze the correlation on different slope levels with soil nutrient contents by collecting the secondary data of land slope and soil chemical properties, analyzed statistically with a simple correlation method. The result showed there was no significant correlation between the slope levels and contents of soil chemical properties. Most of the soil chemical properties have a negative correlation to different slope gradients such as soil pH (r = -0.391), SOC (r = -0.348), total N ( r = -0.169), Available P (r = - 0.039), K content (r = -0.135), Mg content (r = -0.027). where the highest levels of nutrients were found at the lowest level of slope based on the site data. Soil chemical properties are needed to be considered in many tea plantations with different levels of slope and could be used as a recommendation in planning for conservation or restoration of degraded land or soil.

The role of shading trees in coffee farms has been well understood to establish suitable condition for the growth of coffee trees, on the other hand their role in nitrogen cycle in coffee farming is not yet well understood. The objectives of this study are to investigate the influence of various legume shading trees on the concentration of soil mineral N (N-NH4 + and N-NO3-), potential nitrification and to study the controlling factors of nitrification under field conditions. This field explorative research was carried out in Sumberjaya, West Lampung. Twelve observation plots covered four land use systems (LUS), i.e. 1) Coffee agroforestry with Gliricidiasepium as shade trees; 2) Coffee agroforestry with Gliricidiaas shade trees and Arachis pintoias cover crops; 3)Coffee agroforestry with Paraserianthes falcataria as shade trees; and 4) Mixed/multistrata coffee agroforestry with Gliricidiaand other fruit crops as shade trees. Measurements of soil mineral-N concentration were carried out every three weeks for three months. Results showed that shade tree species in coffee agroforestry significantly affected concentrations of soil NH4 +, NO3- and potential nitrification. Mixed coffee agroforestry had the highest NH4+/N-mineral ratio (7.16%) and the lowest potential nitrification (0.13 mg NO2-kg-1 hour -1 ) compared to other coffee agroforestry systems using single species of leguminous shade trees. Ratio of NH4 + /N-mineral increased 0.8—21% while potential nitrification decreased 55—79% in mixed coffee agroforestry compared to coffee agroforestry with Gliricidia or P. falcatariaas shade trees. Coffee agroforestry with P. falcatariaas shade trees had potential nitrification 53% lower and ratio of NH4 + /N-mineral concentration 20% higher than that with Gliricidia. Coffee agroforestry with P. falcataria as shade trees also had organic C content 17% higher, total N 40% higher, available P 112% higher than that with Gliricidia. The presence of A. pintoiin coffee agroforestry with Gliricidiareduced 56% potential nitrification but increased 19.3% of NH4+/N-mineral concentration. The low soil potential nitrification in the mixed coffee agroforestry had close relationship with the high content of soil organic matter. Key words : Nitrogen-mineral, nitrification, shading trees, agroforestry, Coffea canephora, nitrate, organic matter, intercropping,Gliricidia sepium, Arachis pintoi, Paraserianthes falcataria.

Cocoa is one of the agricultural commodities that have important role and are reliable in realizing agricultural development program of Indonesia. The cocoaproduction of Indonesia tends to decrease that caused by in appropriate farming. This research aimed to evaluate the shade management to cocoa productivity and evaluating the correlation between soil quality and the cocoa production with the different shade management. This research was conducted from October 2016 until June 2017 in Kaliwining Experimental Station and Soil Laboratory of Indonesian Coffee and Cocoa Research Institute (ICCRI), Jember, Indonesia. Clones at the trial plots were Sulawesi 1 and Sulawesi 2, 10 years old, and arranged in 3 m x 3 m spacing. The design of this research was conducted by observing parameters of sample trees on cocoa field. This research used three observation plots, with shade trees of leucaena (Leucaena sp.), teak (Tectona grandis), and teak combined with krete (Cassia surithensis) shade. The results indicated that shade species affected the cocoa production. Teak shade gave higher production of cocoa (i.e 3,01 kg.tree-1) compared to other species of shade (1.83 and 1.39 kg.tree-1 for leucaena and teak and krete combination, respectively). The correlation of soil quality with cocoa production showed that soil calcium content, earthworm biomass and soil bulk density were positively correlated with the production of cocoa. Shade species greatly affected the production in combination with the soil quality.

Microclimate monitoring in agroforestry is very important to understand the complex interactions between vegetation, soil, and the environment. Microclimate parameters include air and soil temperature, air humidity, soil moisture, and light intensity. This research aims to develop a new microclimate data recording system for coffee-pine agroforestry, utilizing LoRaWAN and IoT technology to capture real-time microclimate parameters. Unlike traditional data loggers that require manual download on-site, this innovative system enables instant data download from IoT servers, thereby increasing data efficiency and accessibility. The system proved effective, significantly improving the precision of air temperature and humidity, as well as soil temperature measurements, with an average accuracy of 100%. However, soil moisture and light intensity recorded lower accuracies of 81.23% and 82.56%, respectively, indicating potential areas for future research and system refinement. The system maintains a 15-minute sampling period, aligning with conventional datalogger intervals. This represents an advancement in precision agriculture for microclimate monitoring, enabling the data to be utilized in decision-making for agroforestry management, which involves complex interactions between the local microclimate and the broader ecological system. It underscores the significance of sustainable land use as a response to global climate change.

Drought stress and acid soil pH are a form of abiotic stress on acid-dry land. Actinomycetes are a group of transitional microbes that have benefits as bioprotectants, biostimulators, and biofertilizers. This study aimed to determine the optimum growth environment for Actinomycetes at various incubation temperatures (25, 30, 35, and 40 ℃) and media pH (5, 6, 7, 8, and 9) and prove its effectiveness on mustard plants when given drought stress, and increase in acid soil pH. The research was conducted in the LOB greenhouse of PT Great Giant Pineapple using two factors, namely Actinomycetes (F22, F26, F34, F39, and F47) and irrigation (watered and not watered). Observations included Actinomycetes population (CFU mL-1), plant response (percentage of stress, death, survival, recovery), plant growth (plant length, number of leaves, root length), plant production (fresh weight), soil pH, and soil organic matter. Results of this study showed that Actinomycetes F22 gave the highest total population (107 CFU mL-1), and the P4K1, P4K2, and P2K2 treatment combination gave the best results on the observed parameters.

With increasing concerns regarding water resource management and environmental sustainability, understanding land use change and the hydrological health of watersheds is critical for informed decision-making. This study aimed to explore the effect of land use changes on hydrological health resilience in the Rejoso watershed, East Java, using remote sensing techniques and geographic information system tools to characterize the various land cover types. Landsat ETM 7+ satellite imagery was used to describe land cover classes. Hydrological health indicators such as water transmission, water availability during the dry season, and peak rainfall buffer events were systematically analyzed in relation to land cover change conditions. Regression statistical methods were used to measure the impact of land cover changes on hydrological parameters. The study results showed that the area of forest land in the Rejoso watershed tended to increase from 2011 to 2021; on the other hand, the area of agroforestry land tended to decrease along with the increase in upland land. In general, the hydrological health of the Rejoso watershed is decreasing from year to year. The increase in forest area, agroforestry, settlements, and ponds provides a positive response to the hydrological health of the watershed. On the other hand, the increase in moorland and rice fields has a negative impact on the hydrological health of the watershed.

Bromo Tengger Semeru National Park (BTS-NP) in East Java, Indonesia showcases a breathtaking volcanic landscape and cultural allure, drawing hundreds of thousands of domestic and international visitors. Recreational activities involving human and animal trampling and motorized-vehicle traffic caused soil disturbance along their networks of paths, trails, or roads, potentially having a detrimental long-term effect on the tourism industry and environmental services provided by the national parks. However, the extent of the impact of these disturbances on soil properties remains unclear. This study assessed the impact of different disturbance intensities, consisting of undisturbed locations as a control (zone 1), low to medium- (zone 2), and high- (zone 3) disturbance intensities on five different BTS-NP tourism hotspots, including Entrance Wonokitri (EW), Whispering Sand (WS), Parking Temple (PT), Teletubbies Hill (TH), and Entrance Bromo Stairs (EB), on soil properties, including soil compaction represented by soil penetration resistance, and soil infiltration. This study revealed that the higher severity impact of recreational activities on soil compaction was parallel with higher disturbance intensity, particularly in EW and TH. In these particular locations, higher soil compaction is significantly linked to lower soil infiltration, thus needing extra attention and protection. Meanwhile, in WS, PT, and EB, soil infiltration was more controlled by the establishment of a cemented topsoil layer consisting of mixed sand, sulfur, and water. Better management strategies, such as the use of proper trails and road infrastructures, particularly on EW and TH, might be relevant to minimize the impact of recreational activities on these ecologically, economically, and culturally important areas.

Agroforestry systems have significant potential for development in increasing coffee production in Indonesia. Besides providing economic benefits, agroforestry can also have ecological impacts, such as improving soil structure, reducing erosion, and other environmental services. There is a complex interaction between trees, soil, and crops in agroforestry systems, making modeling a valuable approach to unraveling these processes. We utilized the spatial and temporal explicit model WaNuLCAS to (i) evaluate the model's performance in depicting actual events (through coffee production and soil water content), (ii) assess the dynamic processes influencing coffee production and the environmental impact of management patterns, (iii) formulate and simulate optimal scenarios for coffee production optimization. Data from a one-year period involving five agroforestry management patterns for coffee-pine in UB Forest were used as input for the model. The model validation results showed satisfactory and acceptable outcomes for coffee production and groundwater dynamics. WaNuLCAS simulation results indicated that pruning and thinning management are crucial factors in increasing coffee production and are related to creating optimal conditions for coffee plants (light, humidity, and inter-plant competition). Additionally, fertilization management can be combined as a supporting factor to meet the nutritional needs of coffee plants. WaNuLCAS simulation results also suggested that pruning and thinning can improve soil physical properties, but thinning increases surface runoff within the system. This research provides insights into how modeling can be used as a decision-making tool.
