Abstract

Soil serves as the growing medium and source of nutrients for plants. Vertisol soil, however, does bring with it some flaws particularly its physical characteristics. The application of organic fertilizer decomposed with Biofilm biofertilizer, thus, isexpected to improve the physical characteristics of soil and yield of mustard. The aim of the research is to study the effect of the dose of organic fertilizer decomposed by Biofilm biofertilizer to the betterment of Vertisol soil physical characteristics and the mustard yield. The experiment was completed in a field with Randomized Complete Block Design consisting of a single treatment factor in the form of Biofilm biofertilizer. The data obtained from the series of observations was analyzed based on the F test with 95% confidence level followed by Duncan’s Multiple Range Test (DMRT). The variables of the observations involve the mustard plant yield and the soil physical characteristics. The study shows that the application of the organic fertilizer decomposed by Biofilm bio-fertilizer provides significant effects towards the improvement of the vertisol soil’s physical characteristics and the increase in mustard plant yield. The dose 21 tons/ha results in the highest increase in the mustard plant production and the best improvement of the vertisol soil physical characteristics. Organic fertilizer decomposed by Biofilm bio-fertilizer 21 tons/ha helps in developing permeability as much as 685.71%; aggregate stability index 201.6%; organic material 20.74%; and porosity 122.38%. Also, organic fertilizer decomposed by Biofilm bio-fertilizer 21 tons/ha can boost the mustard plant production as much as 4.25 tons/ha compared to the absence of organic fertilizer decomposed by Biofilm bio-fertilizer.

Abstract

Coffee cropping is very sensitive to global warming, thus affecting coffee growers, particularly women farmers and their economies. As unpredictable weather continues to limit the suitability of the majority of traditional coffee-growing regions, women farmers are applying climate-smart agriculture (CSA) practices as a means of climate change mitigation and adaptation through healthy soil identification. Healthy soil is an important indicator that determines the  sustainability of coffee cropping under CSA practices. This study determined women farmers’ knowledge of soil health indicators and perspectives on CSA practices in the coffee cropping region of Sumatra, Indonesia. The qualitative analysis based on the interviews and focus group discussions from 90 women farmers revealed that the most common soil health indicators were soil color and soil organic matter, while the least common was soil ecology. The best climate-smart coffee cropping practices were from the agroforestry system and the least were observed in the long-term conventional tillage system. Over 80% of women farmers express a strong belief in the effectiveness of soil health indicators for implementing successful climate-smart farming methods. The majority of the women recognized the importance of the use of cover crops and strategies to prevent soil erosion. Knowledge about the benefits of soil amendments and intercropping was limited. Women farmers need to have more opportunities for training on various aspects in soil management as a mechanism for climate change adaptation as well as to improve their land for the sustainability of coffee production and their resilience in coffee farming. In order for the farm communities to make the full transition to CSA practices, the success factors and benefits of this management must be demonstrated to the coffee farmers.

Abstract

This paper provides a review of the Toba highland peatlands, focusing on their characteristics, environmental impacts and historical significance. The Toba area was influenced by a super volcano eruption around 74,000 years ago, which resulted in global cooling and the deposition of pyroclastic materials known as the Youngest Toba Tuff. The peatlands in the region formed south of the caldera and are characterised by varying extents and thicknesses. Radiocarbon dating indicates that the peat in Toba highland is approximately 20,000-30,000 years old, making it a valuable carbon stock and a record of the past. However, the drainage of peatlands has led to significant environmental degradation. It has resulted in increased CO2 emissions, reduced water supply for local farmers, loss of biodiversity, air pollution from open fire burning practices, and an increased fire hazard. Understanding the environmental impacts and historical significance of Toba highland peatlands is crucial for conservation efforts and sustainable land management practices.

Abstract

Soils that are acid sulfuric have low productivity, because the physical and biological conditions of this land are characterized by high acidity. Based on the problem of acid sulphate soil, micro remediation research is carried out to fulfill objectives such as the formation of good and sustainable cultivation land. Acid sulphate soil was taken from at Mesuji Ogan Komering Ilir in January 2023. The method in this study was field observation by taking samples using a belgi drill at several points of the land. The study used a pot with a size of 12 cm x 15 cm which was washed 5 times to remove the acid content in the soil. The pot contains 40% soil, 40% sugarcane husk and 20% rice husk biochar. The object used in this study is the ginger plant. High levels of soil acidity can trigger the dissolution of toxic elements and increase the cause of nutrient deficiencies. Adsorption of complexes in the soil will offer sufficient nutrients for plant development if the soil is rich in soluble bases. Conversely, the soil will tend toward acid if Al and H dominate the adsorption complex. The results of this study can be concluded that micro remediation using sugarcane pulp and biochar has a very real impact. The use of sugarcane bag and biochar in this study helped reduce the initial Al of 9.97 Cmol+/kg to 1.65 Cmol+/kg in the soil and lowered the soil acidity level in the initial soil with a pH of 3.26 to a soil pH of 4.94.

Abstract

Lotus is a wild plant in wetlands that have not been widely used but has great potential to be developed as compost tea. Therefore, this research aims to evaluate the content of compost tea made from wild lotus found in wetlands, which has not been sufficiently used but has great potential to be developed as compost tea. It was conducted by testing several methods and compositions of compost immersion, namely A1, A2, A3, and A4 at Aeration 1:5, Aeration 1:10, Non-aeration 1:5, and Non-aeration 1:10, respectively. The results show that the pH value increased until day 8 of immersion and then decreased on days 9 and 10, with a range of 8.0-8.44, in the recommended range. Furthermore, the total dissolved solids in the 1:5 water ratio were lower than the 1:10 of compost and water. The content of nutrients (C-organic, N-total, and P-available), bacteria population, actinomycetes, fungi, and humic acid concentration were higher in aeration treatments for both 1:5 and 1:10 compost and water ratios. In addition, humic acid functional groups in compost tea for all treatments were detected, including OH-phenolic, C=C, C=C, COOH, CH3, secondary amides, and tertiary amides with different wavelengths. Based on these results, it can be concluded that aeration treatment provides better results for the observed variables than non-aeration. Keywords: Compost tea, humid acid, liquid organic fertilizer, lotus, nutrient content.

Abstract

Open-pit mining activities cause environmental degradation such as decreased soil fertility and degradation of plantation. After mining activities is completed, land improvements will be carried out through post-mining reclamation. Low pH conditions, high metal concentrations and low organic matter are the main problems in post-mining activities reclamation land. Reclamation activities carried out by PT. Bukit Asam, Tbk runs continuously from time to time. Mining land that is no longer used for mining activities must immediately carry out land reclamation activities to preserve the environment and maintain ecosystem stability in coal mining areas. The reclamation efforts that have been carried out require vegetation analysis to determine the vegetation growing on the reclaimed land of various ages. This research aims to analyze vegetation using the transect method in reclamation areas aged 1 year, 3 years, 5 years, and natural land as a control. The research results show that all reclaimed land is ultisol soil which is acidic (pH 3.52 – 4.50), and the older the reclaimed land can increase the C-Organic, C-Total and C/N of the soil. The condition of land that is 5 years old also has lower soil temperatures and greater humidity than land that is younger. The Importance Value Index (INP) of seedlings, saplings, poles and trees on reclaimed land at 1 year old is smaller than at 5 years old. The common vegetation found on all reclaimed land of different ages is seedlings (Mimosa pudica), saplings (Malaleuca cajuputi), poles and trees (Malaleuca cajuputi, Acacia mangium).

Abstract

Snakehead fish is one of the freshwater products that has potential in South Sumatra. Utilization of snakehead fish as a side dish and diversification product is for typical Palembang food processing. Most of these preparations used meat as a raw material, leaving waste scales, skin and bones which had the potential to be used as raw materials for collagen. One of the stages of collagen production was soaking in NaOH. The aim of this research was to examine the chemical properties of scales, skin and bones of snakehead fish after soaking in NaOH. The soaking process was carried out in 0.05M NaOH for 6 hours and the water was changed every 2 hours with a ratio of waste to NaOH solution of 1:10. The parameters analyzed included water content, ash content and protein. The results showed the proportion of scales, skin and bones of snakehead fish respectively of 6% scales, 5.7% skin and 4.20% bones. Proximate analysis tests showed levels in snakehead fish scales of 55.67%, skin by 81.15% and bones by 50.80%. The average value of ash content was in snakehead fish scales of 48.14%, skin by 9.27% and bones by 55.42%. The average value of protein content was in snakehead fish scales by 29.60%, skin by 67.59% and bones by 23.66%.
