Malang Regency has a large area of dry land and currently being developed as a center for food crops, especially corn. Corn production in Malang Regency has not provided high productivity, one of which is in Wagir Regency. This study aims to determine the actual land suitability class, determine the characteristics of the land that affects the productivity of corn, determine the actual productivity class of corn, and develop new land suitability criteria using the boundary line method. This research was conducted in May - September 2019 in Wagir District, Malang, using a physiographic survey method based on the Land Mapping Unit. Soil samples were taken at a depth of 0-120 cm (minipit and drilling) at each observation points (42 points) and analyzed in the laboratory (texture, pH, CEC, C-Organic, BS, N-total, P2O5, Potassium, Ca, Mg, and Na). The determination of land suitability class is carried out using the SPKL (Sistem penilaian kesesuaian lahan) application and the modification of the criteria is carried out using the boundary line method. The results of the land suitability evaluation according to the criteria of Ritung et al. (2011) in Wagir District, Malang Regency, included in class S3 and N, with limiting factors in rainfall, Base Saturation, pH, C-Organic, N-total, P2O5, Potassium, slope and erosion hazard. Stepwise analysis result showed that slope and air temperature determined corn productivity in research area. Boundary lines analysis gave results that modified suitability classified as S3 and N which is the same category as actual suitability classes.

Land characteristics are factors that affect crop productivity. Different conditions of land characteristics will cause differences in crop productivity. Evaluation of land suitability can be used as a basis in assessing land quality to determine the factors of land characteristics that cause differences in crop productivity. The purpose of this study was to determine actual land suitability for cayenne pepper, determine which land characteristic affect crop productivity, and modify land suitability based on actual productivity suitability classes. This study was conducted in Wagir District, Malang Regency with a survey method on 8 Land Map Units (LMU) with 42 observation points. Quantitative parameters observed in this study include soil texture, pH, CEC, C-Organic, base saturation, N-total, P-available, exchangeable K, Ca, Mg, Na, and productivity of cayenne pepper in the field. Data analysis was performed by correlation test and multiple regression with the stepwise method. The results showed the actual land suitability class of cayenne pepper in the study area was S3 and N. Modifications to the characteristics of the land that most influence the productivity of cayenne pepper in the field, namely the pH of the soil produce new criteria with classes S1: 6.0-7.6; S2: 5,7â€“6,0; S3: 4,6-5,7; and N: <4,6. The land suitability assessment using the modified criteria resulted in the S3 conformity class, which was similar to the percentage productivity class and the N conformity class that was similar to the percentage productivity class.

Fruit plants in Kediri Regency are classified as having good economic potential, one of which is pineapple. Pineapple plants in Kediri Regency have differences in productivity in each sub-district. The results of interviews with local farmers indicated that the Supiturung Micro Watersheds in Plosoklaten District had low pineapple productivity and were not yet optimal. Therefore, this study aimed to determine the factors causing differences and less optimal productivity of pineapples in the Supiturung Micro Watersheds and analyze the land suitability assessment of pineapple plants in the region. This study used a survey method with a physiographic approach to 10 Land Map Units (LMU) and determined 20 observation points as representatives. Data analysis was performed through correlation and multiple regression tests with the stepwise method to determine the land characteristics that most significantly affected pineapple productivity. Modification of the suitability class and modification of the criteria was carried out utilizing boundary line analysis, with class boundaries according to FAO (1976), namely class S1 (80-100%), S2 (60-80%), S3 (40-60%), and N (<40%) of the potential productivity. The land suitability evaluation results of pineapple plants in the Supiturung Micro Watersheds were included in land suitability classes S2, S3, and N. Based on the stepwise method analysis, the texture is a significant characteristic affecting the productivity of pineapples (p <0.05) with a correlation coefficient value of 0.838. The modification of land suitability criteria with boundary line analysis resulted in changes in one land characteristic, namely soil texture S2, S3, and N. Initially, the rough class included in the N class was changed to S2 level along with the slightly rough level.

Soil quality is the ability of soil that plays a role in maintaining plant productivity, preserving and maintaining water availability and supporting human activities. Soil quality assessment is measured based on indicators that describe important soil processes based on the physical, chemical and biological properties of the soil. The level of soil quality in a plot of land is assessed based on the soil quality index. This research was conducted from August to December 2020 in the Supiturung Micro Watershed, Kediri Regency, East Java using a graphical survey method based on the Land Map Unit. Soil samples were taken at a depth of 0-20 cm at each observation point (20 points) for analysis in the laboratory. Soil quality indicators are determined based on key soil properties with the Minimum Data Set (MDS) method, with soil quality indicators from soil physical properties including texture, bulk density, porosity and soil chemical properties including pH, available-P, exchangeable-K, total-N, organic-C. Soil quality index was calculated by weighting soil quality indicators with criteria which divided into 5 classes, i.e. (i) very low class (0.00-0.19), (ii) low (0.20-0.39), (iii) moderate (0.40-0.59), (iv) good (0.60-0.79) and (v) very good (0.80-1.00). The results showed that the soil in land unit 2 had different limiting factor values on the percentage of sand and dust from the soil texture, the total-N content of the soil and the organic-C content of the soil which caused differences in soil quality. There are two indicators of soil quality, namely the percentage of dust from the soil texture and the total N content of the soil which has the most influence on the soil quality index.

The research that was conducted from April to December 2020 in the Supiturung Micro-Watershed, located on the western slope of Mount Kelud, Kediri was aimed to study the morphological characteristics and soil classification using a topo-sequence approach. Four pedons were observed across the physiographic positions (upper, middle and lower slopes) on dry-land farming land use. The method used in this research included 8 stages, namely the preparation stage, pre-survey, map making, field observations, laboratory analysis, soil classification, data processing, and reporting. On the field, cross-sectional profiles were carried out on four selected pedons by testing the soil profile measuring 1 x 1 meter with a depth of 150-200 cm, followed by soil horizon, soil thickness, texture, structure, consistency, effective depth, type and number of pores, as well as other characteristics. Soil samples were collected from the genetic horizon of the pedons for being analyzed using standard procedures, then taken to the laboratory for soil physical and chemical analysis. Soil morphology with physicochemical properties was then classified based on the Keys Taxonomy of Soil to the Sub Group level. The results showed that each pedon has a different Sub Group. This condition can be caused by many factors, such as differences in epipedon thickness, base saturation values, organic C levels, and other morphological conditions at the time of direct observation. Four pedons have lithologic discontinuities, recognition of these types of lithologic changes is important because pedogenesis and pedogenic interpretations are greatly influenced by changes in the parent material.

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.

Sludge from the paper industry can affect soil fertility due to its organic content. However, sludge as waste has a contamination risk of polluting the soil. This research focused on the chemical properties content of sludge from the paper industry (pH, organic C, macro and micronutrients, heavy metals) and contaminant microbes (E. coli and Salmonella sp.) in order to evaluate to the potency of sludge to be soil amendment. Sludge sample was taken in 0-20 cm depth from Sumengko Village, Wringinanom, Gresik. The chemical properties were measured in Soil Chemistry Laboratory in Soil Science Department, and the biological properties were measured in Pest and Disease Laboratory in the Agricultural Faculty of Brawijaya University. The chemical and biological properties of sludge were compared to quality standards according to Keputusan Menteri Pertanian No. 261/2019 (Kepmentan No. 261/2019) from the Ministry of Agriculture, Indonesia. Sludge from the paper industry has the potency to be soil amendment because it meets the requirement from Kepmentan No. 261/2019. Its pH was neutral (6.9), the macro and micronutrients contents fit the requirement, and it had no microbial contaminant content.Â However, the organic C was under expectation, and it has over Hg content.

Most areas in Indonesia have a high risk of landslides due to geological and geographical conditions. Landslide is affected by natural factors (such as slope stability) and human-made factors (such as land use). Slope stability is influenced by morphological conditions and hydrological conditions. Land use or land cover may affect surface roughness, which determines the infiltration rate into the soil. This study was an attempt to explore the influence of slope gradient and litter thickness on time required for landslides and the volume of landslides. This research was carried out in two different locations, Agro Techno Park and the Experimental Garden of the Faculty of Agriculture. The study was conducted in eight treatments, combinations of three factors, i.e. soil texture, slope gradient, and litter thickness, using ten replications. The duration required for landslides and the volume of landslides were measured. The gradient of the slope has a significant effect on the volume of landslides. An increase in slope at any litter thickness resulted in up to three times more volume. The difference in slope also has a significant effect on the time required for landslides. The clayey texture needs two times the longer time required for landslides to occur. The slope gradient has a more dominant influence than the thickness of litter and soil texture. The effect of the thickness of the litter is getting bigger; on the other hand, the effect of soil texture is getting smaller with increasing slope.

Landslide is one of the geological disasters that often occurs in Indonesia. Landslides can be caused by several factors; there are human factors and natural factors. In principle, landslides occur when the resisting force is smaller than the driving force. Landslides on a small and large scale can occur over time and have a fairly severe impact. Therefore, this study simulated the effect of slope and depth of slip surface on the duration and volume of landslides, which are simulated on two soils with different texture classes. Landslide simulations were conducted at Agro Techno Park and The Experimental Gardens Faculty of Agriculture. The simulation used eight treatments and ten replications consisting of three factors there are soil texture, slope and depth of slickenside. Landslide simulation was conducted using an acrylic box with a size of 100 cm x 50 cm x 75 cm with rain intensity 70 mm hour-1. The variables measured are landslides duration, landslides volume, soil texture and bulk density. Data analysis used an independent sample t-test. The result showed slope and slickenside have a significant effect on landslides duration and landslides volume. The greater the slope, the landslide occurs faster on landslides duration and the greater the volume of the landslide. The deeper slickenside has a longer landslides duration, but the volume of the landslide is larger. It showed that the greater slope has a smaller influence on the depth of slickenside and soil texture on the landslides duration and landslides volume.

Landslide is the process of moving slope-forming material that moves out of the slope. Landslides cause adverse impacts, such as damage to residences, public facilities, death tolls, and damage to agricultural land. Factors for landslides are influenced by disturbing slope stability due to steep slopes, high rainfall intensity, and movement of soil, rock, or a mixture of both. The research was conducted at Agro Techno Park of Brawijaya University (silt loam texture soil) and the experimental field of Faculty of Agriculture Brawijaya University (clay texture soil). The landslide simulation tool used acrylic (100 cm x 50 cm x 75 cm), with an aluminum plate as a base for adjusting the slope. Artificial rain was set to be stable at an intensity of 70 mm hour-1. This study used a combination of three factors, namely soil texture (C: silt loam and J: clay); slope (L1: 40° and L2: 50°); and surface rock (B1: 25% and B2: 50%), so that there were eight treatments with ten repetitions. The landslide duration and volume were measured. The data obtained were then statistically analyzed through the normality test and the unpaired t-test. The results show that increasing slope gradient from 40° to 50° on silty loam texture with similar rock content at the soil surface resulted in 6 times faster and two times larger landslide volume. At a very steep slope, the effect of soil texture and % rocks at the surface would be smaller on landslide duration but became more significant on landslide volume. Generally, the landslide factors can be ranked from the most significant effect as follows: slope gradient, soil texture, and rocks coverage at the surface.
