Tanah pasiran merupakan lahan marjinal yang potensial untuk dijadikan sebagai lahan pertanian. Sifat fisika tanah pasiran merupakan salah satu faktor pembatas karena didominasi pori makro. Pengelolaan dengan aplikasi biochar berbahan baku dari limbah tanaman perkebunan pada tanah pasiran merupakan salah satu alternatif untuk memperbaiki kondisi fisika tanah sehingga dapat mendukung sebagai media tanam pembibitan tanaman tembakau (Nicotiana tabacum) Besuki Na-Oogst. Penelitian dilakukan pada bulan Maret-September 2017 bertempat di Laboratorium Konservasi dan Fisika Tanah, Laboratorium Kesuburan Tanah dan Green House Fakultas Pertanian Universitas Jember. Rancangan penelitian ini menggunakan Rancangan Acak Lengkap (RAL) Faktorial yang terdiri atas 2 faktor yaitu faktor jenis biochar yang terdiri dari biochar limbah kulit kopi (B1), biochar limbah kulit kakao (B2), dan biochar biji karet (B3) dan faktor kedua adalah dosis biochar tersebut yaitu meliputi tanpa biochar/kontrol (D1), 12,5 g/kg tanah (D2), 25 g/kg tanah (D3) dan 37,5 g/kg tanah (D4). Hasil penelitian menunjukkan bahwa interaksi antara dosis biochar dengan taraf dosis yang berbeda memberikan pengaruh terhadap pH tanah, tinggi tanaman, panjang daun, lebar daun, luas permukaan daun, diameter batang, panjang akar, berat basah dan berat kering bibit tembakau besuki na-oogst. Setiap jenis biochar dan dosis biochar masing-masing memberikan pengaruh yang berbeda terhadap perbaikan sifat fisik tanah pasiran yaitu menurunkan nilai berat volume (BV), meningkatkan porositas, water holding capacity (WHC) dan pH tanah.Kombinasi perlakuan yang terbaik untuk pertumbuhan bibit tembakau besuki na-oogst adalah pada jenis biochar biji karet dengan dosis 25 g/kg tanah.

Tourism development becomes one of the alternatives to develop the economy of the community at the village level. The potential of unique and interesting tourism, based on the potential of natural resources becomes an attraction. The problem of human resources becomes an obstacle in the development of tourism. The purpose of this paper is to narrate social engineering strategies in the development of KUPS-based tourism (Social Forestry Business Group). The research method uses qualitative methods, with a research setting in LMDH Rengganis Jember. Criteria-based informant determination technique with purposive technique, data collection method using in-depth interviews focus group discussion and observations. Test the validity of data using source and researcher triangulation techniques, as well as data analysis techniques using flow methods. The results of the study found that the people of Village already have a Durian Village tourist attraction, but no longer operate. This is due to improper management. Social engineering strategies are needed to re-develop that potential. There is a KUPS group that can become social engineering media. The process of social engineering is carried out through several stages, namely, situation mapping, network mapping, figure mapping, citizen facilitation, discourse accompaniment, institutional and structural formation, program formation and citizen participation and program evaluation. Keywords: Agro Wana Wisata, LMDH, Tourism, Empowerment, Social Engineering.

The use of high inorganic fertilizers in conventional agriculture can affect soil fertility. Efforts to improve land fertility in order to increase land productivity and at the same time increase farmers' income require integrated and sustainable agricultural business development technology. Biochar applied to paddy fields is able to increase organic carbon which can provide nutrients for organisms in the soil that will provide nutrients for plants. Sengon waste in Slateng Village is abundant and has not been utilized, while most of the livelihoods of the Slateng Village residents are farmers. This activity aims to provide training to members of the Harapan Farmers Group and the local Mosque Youth to be able to process sengon waste into biochar. This activity is carried out in several stages, namely socialization and practice. The result of this activity is that participants gain knowledge about processing sengon waste and produce biochar fertilizer that is ready to be applied.

Brantas Watershed and its tributaries (approximately 14,103 km2) are essential in supplying water for About 30% of the East Java province population. Management of water resources in this watershed has become a challenging issue. The modelling processes' conformity and results to mimic the existing hydrological processes are still in question. This study aims to analyze sensitive parameters of the SWAT (Soil & Water Assessment Tool) model on the significant watershed. The input model is climate and spatial (DEM, soil layer, LULC) data. The observes the hydrological processes monthly and annually from the model result. Next, Sensitivity analysis using the SWAT-CUP tool and SUFI algorithm shows 18 sensitive parameters. The nine (9) parameters have a more than 50% sensitivity level. The four (4) correlated to the soil layer's runoff generation and water movement. Then, eight (8) parameters are related to baseflow calculation. Simulation results illustrate the strong effect of climate change (especially rainfall) on water yield and sedimentation.

Soil is a solid mineral and organic matter from weathering rocks over the years. The current condition shows many productive lands that are of low quality. Soil quality must be a top priority in land management efforts to support the sustainability of ecology. This study proposes to soil quality index (SQI) assessment of paddy fields in Jember Regency, Indonesia, using the principal component analysis (PCA) method based on spatial data. The research procedure consists of (1) making land units, (2) soil sampling, (3) laboratory analysis, (4) principal component analysis (PCA), (5) assessment of soil quality index (SQI), and (6) Thiessen polygon analysis. The correlation results show the average correlation value < 0.5 (not significant). The soil quality is determined by three main components: total P, silt fraction, and clay fraction. The results of the soil quality analysis showed that 68,888 Ha was in the very low-quality category, and 39,948 Ha was in the low-quality category. Meanwhile, paddy fields included in the medium category are only 3,513 Ha. The addition of organic matter can improve the quality of paddy fields.

Soil salinity problems in the coastal hinterland region of East Java diminish agricultural development and land productivity. Soil leaching is expected to reduce soil salinity. This study investigated the effectiveness of different ameliorant compositions and leaching requirements (LR) in the leaching process. The experiment involved applying ameliorants (T) and leaching (L) treatments to lysimeters filled with saline soil. The ameliorant treatments included biochar, organic matter, and gypsum. The results showed the leaching requirement capacity to reduce electrical conductivity from 5.7 dS m-1 to below 2 dS m-1. Leaching for T0 (without ameliorants) and T1 (10 Mg ha-1 of biochar) required 943 mm of water, while T2 (20 Mg ha-1 of biochar) and T3 (40 Mg ha-1 of compost) required 1052 mm. The T4 (10 Mg ha-1 of compost and 2 Mg ha-1 of gypsum) necessitated 1154 mm of leaching water. The ameliorants’ application and assortment increased the water demand for leaching. The findings indicated a consistent relationship between TDS and salinity, indicating the soil’s dominant presence of salty ions.

Urban development, population growth, high traffic jams, and intensive disaster events are indicators of changing the landscape of the eastern area of East Java. Investigating these changes is vital for planning and environmental protection in the future. This study examines changes in land use and land cover (LULC) during the past 50 years in the eastern part of East Java from 1972 to 2021. The changes are examined by contrasting four maps derived from Landsat images (1972, 1997, 2013, and 2021). The following are the main study procedures: (1) data inventory, (2) field survey, (3) image processing and classification, and (4) interpretation of LULC changes. With Google Earth Engine, all photos are downloaded (GEE). Landsat image classification was completed using the maximum likelihood algorithm with an overall Kappa accuracy of>85%. Eight (8) major classifications are therefore produced by the classification: (1) the pavement or urban area (PUA); (2) heterogeneous agricultural land (HAL); (3) bare soil (BS); (4) paddy field (PF); (5) open water body (OWB); (6) vegetation/plantation (VG); (7) shrubland (SL); and (8) wetlands (WL). In the areas with rapid development, the LULC change is more pronounced, i.e., Pasuruan, Jember, and Banyuwangi Regencies. LULC change in and near mid-regency and the rural regions comes next. Over the past fifty years, regional growth has resulted in increases in PUA (+4.4 percent), PF (+12.2 percent), and VG (+17.9 percent). On the other hand, the development has decreased SL, BS, and HAL by 5.8 and 15.9 percent, respectively (-13.1 percent ). LULC alterations for human activities have profoundly altered the natural landscape. Keywords: East Java, GEE, Image Processing, Landsat, LULC
