Abstract

Universal Soil Loss Equation (USLE) and Geographical Information Systems are two spatial soil erosion analysis models because both have a spatial context. As an important factor, soil erodibility is crucial in determining soil erosion, with C-organic significantly influencing the K value. The main aim of this study is to characterize soil erodibility and soil loss based on spatial simulation of the effects of soil C-organic in a GIS environment. Research findings indicated that by simulating within a GIS environment, C-organic can affect soil erodibility and erosion. Low C-organic levels can increase soil erodibility, while high C-organic levels can decrease it. A reduction in C-organic by 10%, 20%, and 30% will increase K by 1.10%, 1.17%, and 1.21%, respectively. Conversely, adding 10%, 20%, and 30% C-organic will decrease K by 1.12%, 1.27%, and 1.46%, respectively. A 10%, 20%, and 30% increase in C-organic can reduce soil loss by 1.2%, 1.3%, and 1.5%, while a reduction in C-organic will increase soil loss by 1.1%, 1.2%, and 1.3%, respectively. A low K value indicates slight erosion, while a high K value suggests high erosion. Continuous C-organic and properly managing vegetation are necessary to maintain and improve soil quality.

Abstract

Latar belakang: Pertambangan minyak bumi tradisional menyebabkan kerusakan lingkungan terutama pada tanah. Proses pengolahan minyak bumi menggunakan alat sederhana menyebabkan minyak mentah tumpah ke permukaan tanah yang dapat merubah sifat-sifat tanah. Pertambangan minyak bumi tradisional juga dapat meningkatkan pendapatan ekonomi masyarakat lokal karena dikelola langsung oleh masyarakat. Tujuan penelitian ini adalah untuk mengetahui perubahan sifat fisika dan kimia tanah tercemar limbah minyak bumi serta perbandingan pendapatan masyarakat dari hasil penambangan minyak pada tahun 2010 dengan 2023.Metode: Metode penelitian kualitatif digunakan untuk menjawab tujuan penelitian. Analisis deskriptif melalui survey lapangan digunakan untuk menggambarkan kondisi tanah secara fisika dan kimia serta kondisi perekonimian masyarakat lokal yang dilakukan pada tahun 2023. Parameter kualitas tanah yang diperiksa antara lain struktur tanah, konsistensi tanah, tekstur tanah, warna tanah, dan pH tanah yang dilakukan pada 7 titik berbeda dimana sampel titik 4 merupakan sampel tanah tidak tercemar limbah minyak bumi. Perbandingan pendapaan masyarakat deperoleh melalui wawancara terhadap 7 pekerja tambang yang secara khusus mewakili populasi yang diinginkanHasil: Hasil menunjukkan hilangnya konsistensi pada permukaan tanah, tekstur tanah didominasi pasir, warna tanah menjadi hitam pekat, dan pH tanah berubah. Limbah minyak bumi tidak dapat merubah struktur tanah secara partikel, akan tetapi limbah minyak dapat menyelimuti partikel-partikal tanah karena minyak bumi memiliki efek pelumasan. Hasil pendapatan dari pertambangan minyak bumi mengalami penurunan dan tidak lagi dapat memenuhi kebutuhan masyarakat lokal.Simpulan: Limbah minyak bumi dapat merubah sifat fisik dan kimia pada tanah serta meracuninya sehingga merusak ekosistem tanah, sedangkan hasil pertambangan minyak bumi mengalami penurunan akibat jumlah minyak yang akan habis. ABSTRACTBackground:Traditional petroleum mining causes environmental damage, especially to the soil. The crude oil extraction process using simple tolls results in crude oil spilling onto the soil serface, which can alter soil properties. Traditional petroleum mining can also increase the economic income of local communities because it is managed directly by the community. The aim of this research is to determine changes in the physical and chemical properties of soil contaminated with petroleum waste as well as a comparison of community income from oil mining in 2010 and 2023. Method: The qualitative research method is used to answer the research objectives. Descriptive analysis through field surveys is used to describe the physical and chemical conditions of the soil as well as the economic conditions of local communities which will be carried out in 2023. The soil quality parameters examined in clude soil structure, soil consistency, soil texture, soil color, and soil pH, conducted at 7 different points, where sampel  point 4 represents uncontaminated soil samples from oil waste. The comparison of community income was obtained through interviews with 7 mine worker who specifically represent the desire population.Result:The results indicate a loss of consistency on the soil surface, with soil texture dominated by sand, soil color becoming dark black, and a change in soil pH. Petroleum waste cannot change the soil structure in terms of particles, but oil waste can cover soil particles because petroleum has a lubricating effect. Income from petroleum mining has decreased and is no longer able to meet the needs of local communitiesConclusion:Petroleum waste can change the physical and chemical properties of soil and poison it, thereby damaging the soil ecosystem, in contrast, the results of oil mining are declining due to the decreasing amount of oil reserves.

Abstract

Ardirejo Village, Panji Subdistrict, is one of the villages located in the center of Situbondo Regency. Limited agricultural land is the main challenge in meeting the food needs of the local community. An innovative approach to maximizing land use is required, one of which is through vertical farming technology. A community service program was conducted in Ardirejo Village to support the community’s food security. By involving active participation from the local community, this program not only provides practical solutions but also aims to empower the community to produce food independently. First, a comprehensive survey was conducted to identify the main issues and the characteristics of the land in Ardirejo Village. The results of the situational analysis were used to select plants suitable for the land conditions and to design an efficient vertical farming structure. Afterward, workshops were held for the local women’s organization (PKK) and the community on the concept of vertical farming, appropriate plant selection, and necessary care techniques. Regular monitoring and mentoring were provided to the community to ensure the smooth implementation of vertical farming practices. This program also incorporates ongoing education and extension approaches to ensure the community’s knowledge continues to grow. With a better understanding of vertical farming and sustainable agricultural practices, the community is expected to actively manage and utilize this technology."

Abstract

Development of irrigation networks is a crucial element in increasing the efficiency and effectiveness of water distribution for agriculture. This research aims to determine priorities for developing irrigation networks in the Bedadung Irrigation Area, Jember Regency, using the Multiple Attribute Decision Making (MADM) method. This method consider various criteria influencing decision-making, such as physical condition of the channel, land area, water requirements, and level of infrastructure damage. This research involved collecting primary and secondary data through field surveys, interviews with interpreters, as well as reviewing technical and administrative documents related to irrigation networks. Data was analyzed using several MADM techniques, such as Simple Additive Weighting (SAW), Weighted Product (WP), and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to obtain the weight of each criterion and determine development priorities. The results show that the main priority for developing irrigation networks in the Bedadung Irrigation Area is repairing primary, secondary, and tertiary canals that are badly damaged, followed by increasing canal capacity to meet water needs in the dry season. Implementation of the results of this research is expected to increase the efficiency of irrigation water distribution, reduce water losses, and increase agricultural productivity.

Abstract

Site Specific Nitrogen Management Simulated by CropSyst Model under Different Inputs of Nitrogen Fertilizer (Y Wijayanto): Site Specific Nutrient Management (SSNM) has been suggested as the only means for increasing productivity of crops and minimizing the environmental impacts. Despite of this, it is also widely recognized that compared to uniform application, SSNM provides a significant challenges related to the level of management. This is due to the fact that SSNM relates to the management of field / site (or fields / sites) and considers also the spatial and temporal component of factors leading to crop production. A method is urgently required and the most appropriate one is crop model. This study was aimed at using  CropSyst to model yields due to the difference in N applications  and its implementation for SSNM. The study area was located at Jenggawah Village, Sub-District Jenggawah, Jember Regency. Thirty soil samples were taken and six farmer’s fields were chosen for the purpose of modeling. Interview was conducted to obtain the information about the management of farmer’s fields. Yields in each farmer’s fields were used as an integrated indicator. The results suggested that the predicted yields at farmer’s fields were in agreement with those in reality. Simulated yields  based on  different amount of N inputs showed yields were proportional with different N inputs. This study concluded that there do exist a significant amount of potential applications of CropSyst for Site Specific Nitrogen Management

Abstract

Soil is dynamic due to various internal and external processes exerted on the soil, resulting in unique soil characteristics in space in short and long distances. Geostatistics (kriging) is the method of quantifying the spatial variation of soil properties. This research was mainly aimed at applying geostatistics to quantify and interpolate the spatial dependence and structure of three soil properties, namely pH, EC, and Soil Moisture Content (SMC) in a small area. This research was conducted on paddy fields in Mlandingan Kulon Village, Situbondo Regency. Sampling was conducted on an area of   9.2 ha with 31 sample points. Normal data distribution was found for pH and EC, whereas this was not the case for SMC. The results of the analysis showed that most of the pH values   were alkaline (>8), EC values were non-saline (<2 mm/cm), and SMC was in the low category (<20%). The results show that for three soil properties, weak dependencies were observed. The values of Root Mean Square Error (RMSE)  confirmed that kriging with exponential was better compared to the spherical model, resulting in the RMSE of 0.546 (pH), 0.041 (EC), and 1.512 (SMC).

Abstract

Growing rice is complicated because of the interrelationship among production components, one of which is soil conditions. Determination of soil conditions is usually conducted by employing some soil properties. It is no doubt that soil properties have spatial and temporal characteristics. This research used two soil properties: Electrical conductivity (EC) and pH. This study aimed to use and evaluate Inverse Distance Weighted to uncover the temporal changes in pH and EC during the rice growth period. The methods used in the research were field survey, soil sampling, laboratory analysis, and data processing in Geographical Information Systems (GIS). The sample used was 30 and repeated three times under the growth period (vegetative, generative, and ripening). The results showed that there were changes in pH values of the soil in one growing season, and EC values tend to increase from the vegetative to the ripening period.
