Abstract

The use of intensive chemical inputs causes lower availability of nutrients, organic matter, cation exchange capacity, and soil degradation.Therefore, this study aims to assess the soil quality index (SQI) for paddy fields in Jember, East Java, Indonesia. Input data for this study consist of land cover (interpreted from the Sentinel-2 image), soil type, and slope maps. Furthermore, the procedure to calculate soil quality index (SQI) include (1) spatial analysis to create the land unit, (2) preparation of soil sampling, (3) soil chemical analysis, (4) principal component analysis (PCA), and (5) reclassifying soil quality index (SQI). The PCA results showed that three variables i.e., % sand, total- P, and % silt were strongly correlated to SQI, while three classes namely very low, low, and medium of SQI were sufficiently used to describe the spatial variability of the paddy field. Furthermore, approximately 41.14% of the paddy field area were classed as very low while 52.23%, and 6.63% were categorized as low and medium SQI respectively. Based on the results, about 93.37% of paddy fields in Jember Regency still require improvement in soil quality via the addition of ameliorants such as organic fertilizers to increase quality and productivity. This application needs to focus on areas with very low-low quality hence, the quality increased to the medium category.

Abstract

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.

Abstract

The physical quality of soil is determined by quantitative measurement tools, which are expressed in the form of soil quality indices. Methods for determining soil quality have been developed, but none have been standardized. This research aimed to determine the results of the soil physical quality index based on two methods, namely 1) simple additive SQI, and 2) statistically modeled SQI, followed by a sensitivity test to determine which method is more sensitive. This research was conducted in the Rembangan Sub-watershed, which comprises five sub-districts: Jelbuk, Arjasa, Patrang, Sukorambi, and Panti, with elevations ranging from 125.91 to 854.67 meters above sea level. Based on the paired t-test results, the soil physical quality index between the two methods was significantly different, with a p-value of 0.002. Meanwhile, the sensitivity test results showed that the statistically modeled method was more sensitive than the simple additive method. Thus, the statistically modeled method is the method that can be used to assess the soil physical quality index for land management guidance. The poor or low-quality class dominates the soil quality class, covering an area of 2,088.43 ha (79.43%). Land management actions based on soil quality are divided into three criteria: 1) “fixed efforts” for low-quality soil, 2) “enhanced efforts” for medium-quality soil, and 3) “maintenance efforts” for good-quality soil.

Abstract

The Mulyo Farmer Group of Karangrejo village are the fostered villages of the University of Jember and have long been food producers, especially rice and corn, with the potential to become one of the providers of organic products according to SNI 6729:2016. Therefore it is essential to evaluate the implementation of gab against the standard requirements of organic farming systems. Some of the activities carried out are Evaluation and increasing understanding of the application of organic farming systems by continuing the practice of making biochar from agricultural waste for long-term organic fertilizer base materials; Focus Group Discussion and ongoing assistance by the Soil Biodiversity and Fertility Research Group UNEJ. The results of the activities show that the community and village officials are thrilled and open to several activities to be carried out. The results of the initial evaluation using the checklist for fulfilling the requirements of SNI 6729:2016 are based on eight variables related to fresh plants and plant products, indicating that there is no program yet to meet the needs of the organic farming system of SNI 6729:2016 or it has not yet been fulfilled. Even though it has not been fulfilled, the potential for implementing it remains open if based on its main potential, namely organic fertilizer sources and water sources (lowlands with relatively shallow groundwater tables). The existence of many livestock and agricultural waste (which is not harvested) available throughout the year can be used as a source of organic fertilizer in maintaining soil fertility or health.

Abstract

Desa Mayangan merupakan salah satu desa yang terletak di wilayah administrasi Kecamatan Gumukmas Kabupaten Jember, tepatnya di bagian Selatan. Desa Mayangan memiliki luas wilayah 2.466,21 Ha dengan jumlah penduduknya sebanyak 10.864 jiwa. Jarak tempuh Desa Mayangan adalah 43 km dari pusat kota yang menjadikan wilayah ini begitu lekat dengan aktivitas pertanian. Mata pencaharian masyarakat di Desa Mayangan mayoritas adalah sebagai petani maupun nelayan. Pertanian di Desa Mayangan berkembang begitu pesat dengan tanaman budidaya berupa tanaman hortikultura dan tanaman pangan. Namun demikian, pertanian di Desa Mayangan terbatas dikarenakan kondisi lahan suboptimal. Hal tersebut mengingat bahwa Desa Mayangan terletak dekat dengan pesisir pantai, sehingga tanah yang ditemukan berupa tanah berpasir serta tanah lahan rawa. Uji kesuburan tanah secara cepat di lapang penting dilakukanuntuk menduga kandungan unsur hara di dalam tanah. Selidik cepat melalui pemanfaatan alat uji PUTS dilakukan untuk mengetahui status hara tanah, seperti NPK dan pH tanah. Selain itu, dengan menggunakan alat uji PUTS, dapat membantu memberikan rekomendasi pengelolaan berdasarkan status hara tanah. Dengan mengetahui status hara di dalam tanah, maka dapat digunakan sebagai acuan dalam kegiatan pemupukan. Kegiatan pelatihan selidik cepat dengan alat uji PUTS diperkenalkan kepada seluruh anggota Balai Penyuluhan Pertanian (BPP) Gumukmas beserta seluruh anggota kelompok tani. Kegiatan hasil uji tanah di Desa Mayangan memiliki kriteria unsur hara sedang dengan pH masam. Adanya kegiatan ini diharapkan akan mencapai efisiensi pemupukan, sehingga tanah akan menjadi sehat dan tidak bersifat toksik akibat perlakuan pemupukan yang berlebih tanpa mengedepankan aspek keberlanjutan lingkungan.

Abstract

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

Abstract

The coastal area of Waworaha Village, Konawe Regency, possesses significant potential in mangrove ecosystems, water resources, and coastal landscapes that support the development of community-based ecotourism. However, environmental degradation, low public awareness, and threats from extractive activities and land-use conversion have weakened coastal resilience and community welfare. This community service program aimed to increase community participation in mangrove, water, and ecotourism management as a strategy to strengthen coastal resilience. The method employed participatory socialization through interactive lectures, focus group discussions, and field activities, including mangrove planting and environmental management education. The program involved village officials, youth groups, and coastal communities as the main actors in its implementation. The results indicate an increased community understanding of the ecological functions of mangroves as natural coastal protectors and the importance of water resource conservation for sustainable livelihoods. Community participation in mangrove planting activities and ecotourism planning discussions also increased, as shown by active involvement at every stage of the program. In addition, initial community initiatives emerged to develop mangrove-based ecotourism as an alternative, environmentally friendly, and sustainable source of income. The program also fostered collective awareness of the importance of protecting coastal areas from external environmental pressures. Thus, participatory socialization proved effective in enhancing community engagement in coastal environmental management. Increased participation serves as a crucial foundation for strengthening coastal resilience while opening opportunities to improve community welfare sustainably.

Abstract

The decrease in rice production and the high cost of agricultural inputs, especially inorganic fertilizers are important problems faced by farmers in Sukosari village, Sukowono District, Jember Regency. Therefore, farmers need simple, affordable, and environmentally friendly technologies that can use local resources. One possible solution is the use of Local Microorganisms (MOL) as a bio activator to help manage organic materials and support organic farming. This community service activity aimed to improve the knowledge and skills of members of “Kebon Jaya” Farmer Group in producing MOL from bamboo and mimosa roots. The activities included problem identification, preparation, socialization, training, monitoring and evaluation. A participatory approach was used through presentations, demonstrations, and practice involving 20 participants. The results showed that participants were able to understand and practice the main step of MOL production, including preparing and processing the material, mixing the ingredients and fermentation process. The activity increased farmers knowledge and encouraged them to produce MOL independently. It also promoted the use of local resources to support more efficient, independent, and sustainable organic rice farming practices.
