Water is one of the limiting factors in the growth of coffee plants. If plants experience a lack of water, it can inhibit plant growth and, at a critical level, can lead to drought stress and plant damages. The available soil water to plants can be estimated from the level of soil moisture index. The monitoring of soil moisture status can be used in improving the management of coffee plantations. Soil Moisture Index (SMI) is a method that can be used to estimate the level of soil moisture using remote sensing technology using NDVI and LST values. The purpose of this study was to analyze the status and distribution of soil moisture at the coffee plantation; analyze the relationship between vegetation index and soil moisture; and analyzed the relationship between soil moisture status using the SMI method and soil moisture measured in coffee plantations. Results showed that the soil moisture index obtained from Landsat 8 OLI/TIRS image processing had an average value of 0.60. The average soil moisture index at the study site is 1.05. Soil moisture index from the Landsat 8 OLI/TIRS image has a significant positive effect on soil moisture at the study site (y = 7.4996x â€“ 3.4789; R2 = 0.7146**). Â It is suggested that the SMI method can be used to estimate soil moisture in the coffee plantation.

The uneven distribution and intensity of rain cause a shortage and excess of water in dry land farming. It appears that the problem of soil conservation in principle is the regulation of the relationship between rainfall intensity, infiltration capacity, and runoff adjustment. To improve the physical properties of the soil, and the hydrological function of the land use it cannot only be stressed on the coffee plant. Other factors such as soil surface management, such as providing organic matter, covering the soil surface with understory plants, making absorption holes, terraces, waterways and so on, can improve the hydrological function of the land. Rainwater management can be carried out through controlling surface runoff, harvesting rainwater, increasing soil infiltration capacity, managing soil, controlling evaporation and seepage, lining waterways. The use of silt pit parallel is considered quite effective because it is able to produce the lowest surface runoff and sufficient water storage. Silt pit parallel can produce 0.6% of rainfall into surface runoff and also can store water as much as 62.35% of the rainfall that enters the plot. The functions of a silt pit are to increase water infiltration into the soil. On dry land, silt pit functions as a place for harvesting rainwater and surface runoff. Based on the correlation regression test, the amount of surface runoff is closely influenced by the intensity of rain or rainfall.

Orange is a national superior commodity that has an important role in increasing foreign exchange for the country. However, the development of citrus cultivation in Indonesia is still relatively low, probably due to soil fertility degradation. Therefore, this study aimed to analyze the effect of differences in the application of organic fertilizer (form and dose) and their interaction on soil chemical properties, nutrient concentration in the leaf (i.e. N, P, K), and growth in Siamese citrus seedlings. The treatments included the application of a combination of forms and doses of organic fertilizer, namely SD1 (powder dose 2 t ha-1), SD2 (powder dose 4 t ha-1), SD3 (powder dose 6 t ha-1), SD4 (powder dose 8 t ha-1), SD5 (powder dose 10 t/ha), GD1 (granule dose 2 t ha-1), GD2 (granule dose 4 t ha-1), GD3 (granule dose 6 t/ha), GD4 (granule dose 8 t ha-1) and GD5 (granule dose 10 t ha-1). The results showed that there was a significant difference in the interaction between form and dose of organic fertilizer only in the number of primary branches at 4 WAP (weeks after application) with the highest values was found in powder organic fertilizer at a dose of 8 t ha-1 and granules organic fertilizer at a dose 10 t ha-1. In addition, the application of powder organic fertilizer application had a higher plant height at 10-12 WAP as compared to the application of granule organic fertilizer.

Flood is a national disaster in Indonesia. Some of those factors, landform driven factors and non-driven factors in the form of land use management. Pacitan Regency has an alluvial landform that is vulnerable to flooding. BNPB states that the floods in 2018 continued on 07 March 2019, as a massive flood resulted in losses reaching > 600 billion. This study analyzed the potential and risk of flood in Pacitan Regency in 2018, in the past (1998 and 2008), and used it to projected future floods (2030). The research focused on land use change and its impact on flood potential and hazards. The potential and risk of flooding were analyzed using Paiminâ€™s method. The parameter was analyzed from Landsat 5, 7, and 8 images in an unsupervised. The trend will be used for Business As Usual (BAU) analysis in 2030. As a comparison, land use analysis carried out based on Land Ability Class (KKL) and Spatial Planning (RTRW). Data validation using confusion matrix overall accuracy. As a result, there had been an increase of potential floods in high and very high levels (1998 to 2018) around 263.04 ha and 368.99 ha. This continues until 2030 (BAU), around 191.61 ha and 172.8 ha. Land use management with RTRW will increase the potential flooding at a very high level in 2030 + 1088.63 ha. The best land management is the KKL application which reducing the flood potential at a very high level + 1973.39 ha. Accuracy tests conducted at 100 points in 2018 showed that 88 model points matched the flooding event ( 88% accuracy).

A study of soil characteristics dryland productivity of the Supiturung Micro Watershed, Kediri Regency, was conducted by observing the physical conditions of the environment and identifying the morphological and physical properties of the soil in each horizon in the soil profile. Parameters observed were physical properties (texture, bulk density) and chemical properties (CEC, total N, organic C, and base saturation). Data on soil characteristics and plant productivity were then analyzed by correlation and regression to determine the relationship between the two. The results showed that the soil in the study area belongs to the order Inceptisols and Entisols with the dominant subgroup Typic Humudepts. Pineapple plants were spread at SST 5, 7, 9, and 10 with the productivity of 71.18%, 76.35%, 75.76%, and 72%, respectively. Meanwhile, sugarcane was spread in SPL 1, 2, 3, 4, 6, and 8 with the productivity of 71%, 77%, 73.43%, 76.29, and 70.81%, respectively. The results of the analysis show that the land characteristics that affect the productivity of pineapple plants are sand texture with a correlation coefficient value of 0.84 and a regression of 0.71 with a linear equation y= -0.07x + 67.57 RÂ² = 0.53 Land with a sand texture class increasingly has low productivity.

Entisols are newly formed soil types and are commonly found in Indonesia, with a distribution of Â±3 million ha distribution. Entisol Kalidawir has a slightly acidic pH value of 5.8 and contains very low total-nitrogen (N) and available-phosphorus (P) nutrients, calcium (Ca), sodium (Na) and magnesium (Mg) in the exchangeable base are also low and clay loam texture. Low soil nutrients and organic matter can have an impact on plant growth and production Maize is one of the most widely cultivated food crops in Indonesia. The purpose of this study was to analyze various doses of the combination of cow manure and NPK fertilizer on N, P and potassium (K) uptake, growth and production of maize. The results showed that the application of 20 t ha-1 of cow manure and 400 kg ha-1 of NPK fertilizer at observations 27 and 54 days after planting increased growth in height and number of leaves of corn plants and increased nutrient uptake of N, P, and K, respectively. Also reached 1, 0.14, and 0.82 g plant-1 and 5.52, 0.83, and 5.11 g plant-1. In addition, it produces the highest corn production of 10.53 t ha-1.

It is feared that the decline in productivity of plantation crops in Malang Regency, so it is necessary to analyze the soil productivity index at ATP Jatikerto as one of the locations for producing plantation plants. This soil productivity index assessment was presented in the form of a map to make it easier to see the distribution pattern of soil productivity in ATP Jatikerto. The results of the calculation of the productivity index showed that the land potential varied from land with poor to sufficient criteria, namely maize land with an IP (Productivity Index) of 43.27, which is included in the bad IP criteria. In coffee, cocoa, sugarcane, papaya, and citrus fields, they are categorized as moderate with IPs of 50.14, respectively; 45.82; 39.45; 52.26; and 45.82. Actions that can be taken to overcome the problem of decreasing productivity are to carry out regular fertilization, both organic and inorganic, to keep nutrients available for cultivated plants, as well as adding organic matter using litter which not only serves to add nutrients but can also be used as organic mulch to prevent raindrops from falling directly to the ground so that the loss of topsoil can be minimized and increase the population of soil microorganisms. In addition, it can also use bagasse, blotong or manure which can improve the physical condition of the soil by reducing soil density and increasing macropores for better root growth, and ultimately increasing sugarcane yield.
