Abstract

Welang watershed is a watershed located in Pasuruan Regency. Welang watershed has 522.89 km2. Changes that occur in the soil due to uncontrolled use can reduce soil productivity and reduce the main function of the soil. The factor causing soil damage is the increase in population in an area that is not following its function. The measurement of the standard criteria for soil damage refers to the Regulation of the Minister of the Environment No. 07 of 2006. This study aims to assess the status of land use against soil damage. The results showed that the Welang watershed in the central region of Pasuruan Regency had a damaged status, namely lightly damaged (R.I). Redox as a limiting factor in each different land use, namely irrigated rice fields, rainfed rice fields, mixed gardens, dry fields, and forests) in Purwosari and Purwodadi sub-districts. Efforts were made to improve the damage status with redox limiting factors with the addition of organics. The addition of materials is carried out by periodic fertilization for physical, chemical, and biological improvement of the soil.Key words: Damage, Welang Watershed, Land

Abstract

Soil color is the important due to its relation with other soil properties. It is usually analysis with the standard Munsell Soil Color Charts (MSCC). While other properties including organic matter need to be analyzed in the laboratory. The objective of this study is to develop IoT sensor for soil that is able to detect rapidly soil color and other properties including C-organic, pH, and cation exchange capacity (CEC). Soil color data from five soil type was analyzed using the MSCC and used as input data to the IoT (internet of things) sensor. In addition, soil properties obtained from lab tests was also included. The designed IoT sensor was used to detect soil color and soil properties of 7 soil types used as the testing samples. The sensor performance was evaluated by comparing soil properties predicted using IoT and lab analysis. Results showed the use of IoT soil sensor succeeded in determining soil characteristics including pH, CEC, and C-organic based on soil color. In addition, the soil color sensor had high accuracy to predict soil properties with a very small difference compared to the lab analysis, namely 0.01% difference for C-organic, and other properties of <5% difference. The development of IoT soil sensor will be important in the fields of agriculture and land management. Keywords: Acidity (pH), CEC, C-Organic, IoT, Soil Color.

Abstract

Sub-watersheds are formed from the interaction process of soil-forming factors such as geology, topography, and organisms. Each interaction process results in different characteristics of soil physical properties. Physical characteristics can serve as the main reference in planning, implementing, and evaluating appropriate management of Sub watershed Areas. The purpose of this study is to examine the characteristics of soil physical properties in the Manten Sub-watershed. This research uses an exploratory approach with a field survey approach through 3 stages of activities, namely pre-survey, survey, and post survey. Each land use was repeated five times to represent the area of each land use. The parameters observed include texture, bulk density, particle density, permeability, and porosity. The results show that the physical properties of the soil in the Catchment area of the Manten Sub-watershed, Malang Regency, are very different in each land unit. Soil texture is dominated by the loam class (T1, T4, T5, S1, S2, S3, K3, and K4). Based on the research results of soil physical properties in the catchment area of the Manten sub watershed, moorland use has better soil physical properties than dry field and paddy field land uses. The poor soil physical properties in dry field and paddy field land uses may be caused by excessive land cultivation and low soil organic matter content. Keywords: Catchment area, Land use unit, Soil physical, Sub-Watershed.

Abstract

The biodiversity or diversity of macrofauna depends on abiotic environmental factors and biotic environmental factors. Macrofauna plays a role in decomposing organic matter so that it can restore and maintain soil productivity. The study aims to determine the diversity of soil macrofauna in the Complex Agroforestry system and its effect on the decomposition of coffee litter. The research was carried out by observation of soil macrofauna and observation of litter decomposition rate using RAK which was composed of 2 factors, namely the type of agroforestry and the difference in the age of coffee plants. The results showed that the macrofauna diversity of soil in Complex Agroforestry and Simple Agroforestry was not different because the amount of shade and diversity were almost the same. The Soil Macrofauna Diversity Index showed a low category (H' < 2) with an average INP value of 40 – 48%. Biotic factors (litter production) and abiotic factors (temperature and humidity) affect the diversity of good macrofauna. A high macrofaunaa population will affect the rate of decomposition of debris where macrofauna plays a role in remodeling organic matter.

Abstract

This study aimed to evaluate the effect of humic-silica application on P availability and P uptake by corn in land contaminated with heavy metals. The experiment was arranged in a Completely Randomized Design (CRD) with two treatment factors. The first factor consisted of three industrial locations: the pharmaceutical industry, the animal feed industry, and the paper industry. The second factor consisted of four levels of humic-silica application (in kg/ha): 0, 10, 20, and 30. Observations were made at the age of 14 and 70 days after planting (DAP). The parameters included soil organic carbon, Cation Exchange Capacity (CEC), soil P-available, and total P uptake by corn plants. Results showed that the humic-silica application at 20 kg/ha had a significant effect on P-available and P uptake by corn plants. This positive effect was consistent in the three industrial locations, both in 14 DAP and 70 DAP observations. These findings indicate that the use of humic-silica at 20 kg/ha has potential to reduce the negative impacts of heavy metal pollution on the availability of plant nutrients in industrial lands. This study provides insight into strategies for managing industrially contaminated lands to increase agricultural productivity, especially in terms of increasing the availability and absorption of phosphorus by corn plants.

Abstract

Soil erodibility is an important factor in determining soil loss. The objective of this study was to evaluate the soil erodibility value based on the Wischmeier-Smith Method. The study was carried out in Jatiarjo Village, Prigen District, Pasuruan Regency, at four land use units (LUU), including Mounts (MO), Mixed Garden (MI), Monoculture Garden (MG), and Shrubs (SR). Wischmeier-Smith algorithm was used to determine the erodibility values and classification. Results showed that shrub was identified as the land use with the highest potential for erosion and erodibility value. The correlation between clay fraction and erodibility has a negative value wit r = -0.76, while other fractions had r value < 0.5. This implied that the clay fraction and soil erodibility have an inverse relationship, where each increase in the clay fraction value will be followed by a decrease in the erodibility value. One way to reduce soil erodibility is to increase plant diversity on the land. Apart from adding organic matter, a variety of plants also have roots that are able to bind soil aggregates and help absorb water into the soil, thereby reducing water flow on the surface. If conservation is not taken seriously, it can undoubtedly result in.

Abstract

This study aims to evaluate land suitability for enhancing the production of key crop commodities in Ngancar District, Kediri Regency, particularly pineapple, coffee, and mango. The district has high soil fertility potential due to its location at the foot of Mount Kelud. The research methods include land surveys, soil sampling at depths of 0-30 cm and 30-60 cm, and laboratory analysis to measure soil physical and chemical properties. Results indicate that the land in the study area generally falls into the marginal suitability class (S3), with the main limiting factors being soil texture dominated by sandy loam, low K₂O levels, and high rainfall that affects pineapple growth. Slope gradient is also a limiting factor for coffee and mango cultivation. Adjustments in soil management, such as timely fertilization and planting crops with strong root systems, can improve the land's suitability potential. In conclusion, although the land in Ngancar District has certain limitations, optimizing land use can enhance the productivity of key commodities, particularly through improved soil management and appropriate fertilizer use. Keywords: Crop commodities, Land Assessment, Land Degradation, Mount Kelud.

Abstract

Land damage will reduce the quality of land function and increase the area of critical land. Land use in the Manten Subwatershed cause changes land function that have the potential to increase the criticality level of a land. This study aims to measure the soil quality index from the chemical aspect of critical land in the Manten Subwatershed. Surveys at sampling points were conducted on three types of land use (kaleyard, rice fields, and dry fields) combined with three levels of critical conditions (not critical, critical, and potentially critical). Each combination was carried out at three locations, involving 27 sampling points. Soil quality indicators measured in terms of chemistry include soil pH, nitrogen, phosphorus, potassium, and soil organic matter content. The results of the study showed that all sampling points had a very low soil quality index with an SQI score between 0.06 and 0.122 and an average pH that tended to be low (<6), N-total content of 0.137%-0.308%, phosphorus of 70.97-655.66 ppm, exchangeable potassium of 0.490-2.690 me/100 g, and organic matter 0.023%-0.044%. The practice of adding organic matter needs to be implemented to improve soil quality. Keywords: Critical Land, Land Use, Chemical Properties, Soil Quality Index, Sub Watershed.
