This research aims to compare fresh biochar and NPK-enriched biochar and their decomposition levels and nutrient absorption efficiency in acid soil with soybean. Factorial randomized block design was used in this experiment and consisted of two factors. The first factor, biochar source, comprised four levels: B0: biochar without NPK, B1: rice straw biochar + NPK, B2: soybean straw biochar + NPK, and B3: wood biochar + NPK. The second factor, biochar enrichment, comprised four levels: D1: 0.5 tons ha-1, D2: 2.5 tons ha-1, D3: 5.0 tons ha-1, and D4: 10 tons ha-1. Each treatment was replicated three times, yielding 48 experiment units. The results showed that biochar enrichment with NPK affected the decomposition level. The percentage of increasing decomposition in enriched wood biochar (0.09%) was lower than rice (0.28%) and soybean (0.53%) straw biochar. An increase in NPK absorbance efficiency and soybean dry weight was evident in NPK-enriched biochar. The highest N absorbance efficiency occurred in wood biochar (21%), followed by soybean and rice straw biochar, respectively, while the highest P and K absorbances were found in rice straw biochar (35% and 26%, respectively), followed by wood and then soybean biochar.

Kelembaban tanah permukaan memainkan peran kunci dalam siklus hidrologi karena mengontrol fluks air antara tanah, vegetasi, dan atmosfer. Selain itu, pengetahuan tentang kelembaban tanah sangat dibutuhkan dalam banyak studi pertanian dan aplikasi yang berkaitan dengan pengelolaan irigasi. Sistem irigasi tetes merupakan salah satu alternatif teknologi aplikasi irigasi. Penerapan sistem irigasi ini mampu meningkatkan efisiensi penggunaan air pada lahan kering. Penggunaan air irigasi tetes pada tanaman hanya di sekitar daerah perakaran saja. Tetesan irigasi di daerah perakaran tanaman dapat menekan aktivitas tanaman pengganggu. Kebutuhan air di daerah perakaran berbeda pada setiap tanaman. Komunitas ilmiah telah dengan jelas mengakui pentingnya kelembaban tanah sebagai masukan untuk aplikasi ilmu bumi, mengembangkan pendekatan dan teknik baru untuk pemantauan, pemodelan, dan penggunaan data kelembaban tanah. Pada penelitian ini kebutuhan air irigasi diterapkan pada tanaman durian. Penelitian yang dilakukan bertujuan untuk mengetahui pola kelembaban tanah pada tanaman durian. Kelembaban tanah mempunyai dua pengertian yang berbeda, sebagai kelembaban volumetris (θ) dan kelembaban gravimetris (w). Penentuan besarnya kebutuhan air bagi tanaman secara teliti pada umumnya terbentur pada kesukaran untuk mendapatkan hasil pengukuran yang teliti di lapangan. Kelembaban tanah pada hasil pengukuran berkisar antara 0.228 (cm3.cm-3) hingga 0.699 (cm3.cm-3).

various parties involved in the agricultural sector about the importance of health and environmental sustainability. Agribusiness is important because of positive demands from consumers, especially the food sector. Technological developments and people's welfare have caused the demands of food consumers to change, namely not only demanding quantity but demanding quality, safety, health, and food security. The concept of development in the agricultural sector should not only focus on increasing product productivity, but also pay attention to natural balance, product quality and safety. This study uses five variables, namely revenue, costs, income, R/C ratio and ICS. The analytical method used in this study was qualitative analysis to describe the application of ICS at the research location and farmer characteristics, while quantitative analysis was performed to calculate farming costs, revenue, income, and R/C ratio. The value of the R/C ratio is 2.32, meaning that each cost of Rp. 1.00 then it can generate a profit of Rp. 2,32. An R/C ratio value of more than 1 indicates that the income generated by organic coffee farmers in Sleman Regency is higher than the costs incurred. The value of the R/C ratio is 2.32, meaning that each cost of Rp. 1.00 then it can generate a profit of Rp. 2,32. An R/C ratio value of more than 1 indicates that the income generated by organic coffee farmers in Sleman Regency is higher than the costs incurred. The value of the R/C ratio is 2.32, meaning that each cost of Rp. 1.00 then it can generate a profit of Rp. 2,32. An R/C ratio value of more than 1 indicates that the income generated by organic coffee farmers in Sleman Regency is higher than the costs incurred.Based on calculations, it is known that the average value of efficiency (R/C ratio) of organic rice farming in Sleman Regency is 6.27. This shows that organic rice farming in Sleman Regency is efficient and profitable. The value of the R/C ratio is 6.27, which means that each cost of Rp. 1.00 then it can generate a profit of Rp. 6,27. R/C ratio values that are more than 1 indicate that the income generated by organic rice farmers in Sleman Regency is higher than the costs incurred

Sustainable development on a regional scale can be accelerated if organic farming management methods are adopted in Indonesia. This research utilized the Sustainability Assessment of Food and Agriculture (SAFA) framework due to its comprehensive coverage of sustainability and accessibility for producers and decision-makers. This study compared the sustainability of certified and non-certified organic as well as non-organic farms in Sleman Regency across four dimensions: good governance, environmental integrity, economic resilience, and social welfare, focusing on how different farming practices impact sustainability indicators. A total of 9 farmer groups participated in this study, categorized based on their farming practices and certification. The results unveiled that certified organic rice farming achieved the highest sustainability score. Specifically, certified organic farmer groups excelled in the economic sub-themes of product quality and information (82%) and local economy (90%), as well as the social sub-themes of labor rights (86%) and equality (80%). Meanwhile, non-certified organic farming performed highly in the local economy sub-theme (82%). In contrast, non-organic farming scored the highest in the sub-themes of investment economy (80%) and fair-trade practices (81%) but demonstrated low scores in holistic management (40%) and impact on the atmosphere (36%). Hence, certified organic rice farming outperformed non-certified organic and non-organic practices regarding sustainability. Key factors affecting farm sustainability included organic fertilizers, sustainable water management, local economic improvement, equity, labor conditions, biodiversity preservation, and product quality and information. These findings highlight the significance of adopting certified organic farming to achieve higher sustainability in agriculture.

Abstract: Land compatibility can contribute to the optimization of agricultural land use, because this evaluation is used to determine the most appropriate spatial plan for current and future land use. Identifying the suitability of agricultural land is necessary to adapt to increasing food needs caused by expanding population, environmental pollution and climate change. Therefore, this research was conducted to assess the suitability of snake fruit plants. Various factors were considered in this research, such as rainfall, temperature, nutrient availability (wa), rainfall density (rc), organic carbon (nr), slope, flood hazard (fh) and erosion hazard (eh). The results of the classification of land suitability classes in the Sleman Regency area, in this case, are that snake fruit plants in most areas fall into the criteria for land suitability class S2 or quite suitable. The results are with an area of??42,150 Ha or with a percentage of 73.4% of the land suitability class S2 or Sufficiently Suitable. (Medium Suitable) is land that has quite heavy barriers to maintain the level of management that must be carried out. In the land suitability class S1 or very suitable in the research area with an area of?? 10625 Ha or with a percentage of 18.5, the land suitability class Very Suitable (Very Suitable) is land that has no boundaries. The results of the land suitability assessment, both actual and potential, can be carried out by improving efforts such as improving drainage, adding organic material, planting according to contours, fertilizing. Keywords: Horticulture, Uniformity, Land Suitability, Organic Farming, Snake Fruit
