Abstract

This study investigates the microbial populations during different coffee fermentation processes and their impact on coffee quality. Bacillus, Pseudomonas, and endophytic populations in coffee beans undergoing natural saccharic and natural lactic fermentation remained unchanged compared to fresh coffee beans. However, a notable increase in Bacillus population occurred in honey saccharic fermentation, possibly attributed to the high sugar content in the mucilage, supporting bacterial growth. Additionally, the introduction of Lactobacillus and Saccharomyces during fermentation enhanced sugar consumption and influenced the final coffee quality, particularly aroma profile and nutritional composition. Varietal differences were observed, with Bacillus population decreasing slightly post-fermentation, especially in honey saccharic and natural lactic processes. This decline may be attributed to the dominance of Saccharomyces and Lactobacillus, antagonistic to Bacillus, and the fermentation conditions leading to decreased pH, unfavorable for Bacillus. These findings highlight the intricate microbial interactions and their implications for coffee fermentation and quality.

Abstract

Lead (Pb) heavy metal pollution on rice fields in Rancaekek is caused by the disposal of textile industry waste which is not perfectly processed. The impact is a decrease in soil fertility which can threaten the food quality and agricultural sustainability. The application of N Bio-Organomineral fertilizer is one of the efforts to improve the quality of rice fields polluted with heavy metals Pb and high Na content. This research aims to find out the effect of N Bio-Organomineral fertilizer on pH, NO3-, Na, C-organic soil, solubility of soil Pb and uptake of plants Pb. The experimental design used a Randomized Block Design (RBD) with eight treatments and four replications consisting of: 0 (control); urea 250 kg/ha; and the variation in the dose of fertilizer is 250; 500; 750; 1000; 1250; 1500 kg/ha. N Bio-Organomineral fertilizer is a modification of N fertilizer based on urea, zeolite, activated charcoal and compost enriched with Bacillus subtilis with formulation 60:20:10:10. The results showed that the application of N Bio-Organomineral fertilizer could increase the NO3- and C-organic content of the soil and reduce the Na-dd and Pb uptake of plants. Treatment of 500 kg/ha N Bio-Organomineral fertilizer was the best dose in increasing the NO3- and Corganic content of the soil and reducing Na-dd and Pb uptake of plants

Abstract

Sustainable agriculture is the proper solution for improving the fertility of Inceptisol, which is potentially suitable for soybean cultivation. Balanced fertilization, using both inorganic fertilizers and nitrogen-fixing biofertilizers, is one appropriate solution. To enhance the effectiveness of nitrogenfixing bacteria, a suitable carrier material is needed. This study aims to assess the potential of different carrier materials for Azotobacter and Bacillus on the growth and yield of soybeans on Inceptisol in Jatinangor. The research employs a Randomized Block Design with two factors: NPK dosage (0%, 50%, and 100%) and Azotobacter sp. and Bacillus sp. in various carriers (compost, bran, and Azolla powder) with 3 replicates. The results indicate that the interaction of Azotobacter sp. and Bacillus sp. in carriers had no significant effect on the height and chlorophyll content of soybean plants. The 100% NPK dosage yielded the highest number of pods compared to the 50% and 0% dosages. The treatment of Azotobacter and Bacillus in carriers did not significantly affect the number of filled pods, plant height, or chlorophyll content.

Abstract

Efektivitas inokulan Azotobacter sp. dan Bacillus sp. sering kali berkurang ketika diaplikasikan di tanah asam seperti Inceptisol, sehingga diperlukan upaya untuk meningkatkan kinerjanya dalam kondisi ini. Salah satu strategi adalah memilih bahan pembawa inokulan yang tepat seperti tepung Azolla pinnata dan kompos. Tujuan penelitian ini adalah untuk mengevaluasi kepadatan populasi inokulan, pembentukan bintil akar, berat kering akar, dan jumlah daun trifoliat pada tanaman kedelai yang diberi perlakuan tepung A. pinnata dan kompos sebagai carrier inokulan Azotobacter sp. dan Bacillus sp. Penelitian ini dilakukan pada Agustus 2022 hingga Januari 2023 di Laboratorium Biologi Tanah dan Kebun Percobaan Ciparanje, Departemen Ilmu Tanah dan Sumber Daya Lahan, Fakultas Pertanian, Universitas Padjadjaran. Penelitian menggunakan Rancanagan Acak Kelompok Faktorial dengan dua faktor yaitu faktor pertama berupa pemberian pupuk NPK dengan dosis 100% (300 kg/ha), 50% (150 kg/ha) dan 0% (0 kg/ha) dan faktor kedua adalah perlakuan inokulan kultur cair, inokulan dalam kompos, inokulan dalam tepung Azolla, inokulan dalam campuran kompos dan Azolla yang masing-masing diulang sebanyak tiga kali. Hasil penelitian menunjukkan bahwa carrier tepung Azolla dan kompos meningkatkan populasi Azotobacter spp. dan Bacillus spp. di rizosfer. Inokulan dalam campuran pembawa kompos dan tepung Azolla menghasilkan berat kering akar dan jumlah bintil tertinggi secara signifikan. Inokulasi kultur cair Azotobacter sp. dan Bacillus sp. atau inokulan padat dengan bahan pembawa tepung Azolla menghasilkan polong kedelai yang setara dengan aplikasi NPK 150 kg/ha. Aplikasi inokulan dalam tepung Azolla, kompos, atau campuran keduanya menghasilkan bobot 100 biji yang tidak berbeda nyata, namun, bobot 100 biji setara dengan perlakuan yang menggunakan dosis NPK 300 kg/ha di Inceptisol

Abstract

Soil fertility is recognized as a crucial factor in supporting plant growth and productivity. The utilization of biofertilizers as environmentally friendly fertilizers is aimed at enhancing soil fertility and plant productivity. This study aims to explore the potential of local material for developing local wisdom biofertilizers (LWB) for achieving sustainable agriculture. A systematic literature review was conducted using bibliometric analysis, Preferred Reporting Items for Systematic Reviews, and Meta-Analyses (PRISMA) method, employing the Scopus search engine with the keywords "local AND wisdom AND biofertilizer" OR "biofertilizer" OR "local AND microorganism" OR "soil AND health OR crop AND productivity OR sustainable agriculture". The search yielded 704 articles, of which 11 were deemed eligible after selection. Based on the literature review, it was found that there are local materials, including fish waste, seaweed, Azolla, fruit waste, Moringa oleifera, microalga, bamboo roots, banana hump, golden snail, mangrove leaves, fruit, and vegetable waste that can be used as raw materials for LWB to improve soil health, plant growth, and productivity. The development of LWB as a new fertilizer technology faces challenges such as lack of regulations, low public trust, limited farmer awareness, weak promotion, and raw material shortages. Further research is needed to intensively study and enhance the effectiveness of LWB through enrichment using beneficial microorganisms.

Abstract

Bioremediation is a method for restoring land contaminated by waste, utilizing the activity of microorganisms to reduce and eliminate the toxicity levels of pollutants. A major challenge in the bioremediation of petroleum waste is the extremely low solubility of petroleum and the limited capacity of hydrocarbon-degrading bacteria. This study aims to examine the potential of petrophilic bacteria and Azotobacter chroococcum in enhancing hydrocarbon degradation efficiency, the viability of petrophilic bacteria and Azotobacter spp., and soil acidity characteristics (pH) during the bioremediation process. The experiment used a factorial randomized complete block design (RCBD) with two factors and three replications. The first factor was the type of petrophilic bacteria which consisted of two levels: (a0) without petrophilic bacteria, and (a1) 2% petrophilic bacterial inoculation per waste load. The second factor was the dose of Azotobacter chroococcum, consisted of four levels: (b0) without A. chroococcum, (b1) 0.5%, (b2) 1%, and (b3) 1.5% A. chroococcum. The results showed that soil pH decreased from a range of 8–9.1 to 6.6–6.7 after the bioremediation process, despite no significant differences were detected between treatments. Biodegradation efficiency increased with the application of A. chroococcum and petrophilic bacteria compared to the control, although no significant differences were found between the bacterial treatments. The application of A. chroococcum at 1% and 1.5% significantly increased Azotobacter population density. Overall, petrophilic bacteria and A. chroococcum demonstrated high effectiveness in improving biodegradation efficiency.

Abstract

Inceptisols hs a potential to be developed as a growth medium for tomato cultivation. The low to moderate fertility of Inceptisols can be improved by applying compost derived from various types ofagricultural waste, which can increase soil organic matter content, support the growth of nitrogenfixingrhizosphere microbes such as Azotobacter sp., enhance soil fertility, and ultimately improvetomato yield. This study aimed to analyze the effects of different types and application dosage ofagricultural waste compost on the population of Azotobacter sp., soil organic carbon, total nitrogen,and the yield of tomato plants (Lycopersicum esculentum Mill.) grown on Inceptisols. A greenhousepot experiment was conducted with a Randomized Complete Block Design with ten treatments andthree replication, consisted of control (no compost) and three types of compost (rice straw, sugarcanebagasse, and empty oil palm fruit bunches) applied at rates of 10, 15, and 20 tons ha⁻¹. Theexperimenal result showed that agricultural waste compost significantly increased the population ofAzotobacter sp., soil organic carbon content, and tomato yield, but had no significant effect on totalsoil nitrogen. The application of rice straw compost at a dosage of 20 tons ha⁻¹ was the most effectivetreatment to increase Azotobacter sp. population, fruit weight, and the number of tomato fruits perplant.
