Abstract

Agricultural soil is possibly threatened by lead (Pb) contamination due to the intensive use of fertilizers. The rhizobacteria were recommended for the bioremediation of soils contaminated by low concentrations of Pb. The experiment was conducted to observe the Azotobacter's ability to proliferate in Pb-contaminated broth and to decrease the Pb availability in soil, Pb uptake by sweet potato roots, and sweet potato growth. The resistance test was performed by growing five Azotobacter isolates in N-free broth with various Pb levels. A pot experiment was conducted in a factorial randomized block design to test three levels of Pb in soil and two Azotobacter isolates. The results showed that Azotobacter Azv4 and A. choroococcum were resistant to 100 mg L-1 Pb in N-free broth. In the pot experiment, Azotobacter Azv4 Inoculation caused less Pb in soil and roots of sweet potatoes grown in Pb-contaminated soil than A. choroococcum. Either Azotobacter or Pb soil did not influence vine length. However, Azv4 was more prominent in increasing branch number, root volume and length; higher Pb in soil reduced branch number but did not affect root parameters. Azotobacter Azv4 increased more shoot and root dry weight compared to A. choroococcum, but both isolates did not change the shoot-to-root ratio (S/R). The Pb contamination only reduced root dry weight and reduced the S/R. This research considered utilizing rhizobacteria Azotobacter for reducing Pb levels in soil and roots; and increasing sweet potato biomass.

Abstract

Silicon (Si) is a beneficial element for rice plants. However, evaluating the Si availability status of paddy soil is rarely done. This study aimed to investigate the Si availability for plant (SiAP), spatial distribution, SiAP correlations with some soil properties and the effect of SiAP status on the rice yield. This study used a survey method to collect paddy soil and water sample. The pot experiment method was used to evaluate paddy plant response to SiAP level. Based on K-means, cluster analysis showed that soil SiAP was categorized low (< 147 mg SiO2 kg-1), moderate (147 – 224 mg SiO2 kg-1) and high (> 224 mg SiO2 kg-1). The SiAP status of the paddy soil area of 26,395 hectares (25%), 61,744 hectares (59%) and 15,952 hectares (15%) was categorized as low, moderate and high, respectively. This present study revealed that the upland area paddy soil has higher SiAP than the lowland area. Total silicon dioxide (SiO2) and clay percentage were negatively correlated with the SiAP in soils. Silicon addition to the paddy soil with SiAP status showed low to high increase in rice yield by 0.2%, 3.9% and 2.7%.

Abstract

Intensive use of inorganic fertilizers causes damage to soil ecosystem and environment. While, the utilization of biofertilizers holds significant potential in enhancing soil health and increasing crop yields as a viable solution for achieving more sustainable agricultural practices. This literature review explores biofilm biofertilizers (BBF) and plant growth promoting rhizobacteria (PGPR), examining their applications in improving soil-plant health, growth, and productivity. Employing Systematic Literature Review (SLR) methodologies, scientific literature from 2012 to 2022 was analyzed following PRISMA guidelines. Reputable journals indexed in Google Scholar and E-Journal Springer were selected, and relevant keywords were used to gather primary references. Results demonstrate that PGPR from various genera (Serratia sp., Bacillus sp., Pseudomonas sp., Streptomyces sp., and Cyanobacteria) produce growth promoters like indole-3-acetic acid (IAA), gibberellins, ethylene, and cytokinins. Combining BBF with chemical fertilizer can reduce chemical usage by up to 48%, reducing reliance on them. BBF containing PGPR exhibit potential to enhance agronomic of food crops traits and promote sustainable farming practices in Indonesia.Keywords: Systematic review, Biofilm, Biofilm Biofertilizer, Sustainable farming, Indonesia

Abstract

Konsumsi buah-buahan sangat dianjurkan untuk peningkatan gizi masyarakat dan ketahanan tubuh. Namun demikian kemampuan untuk membeli buah-buahan masih terbatas karena pada umumnya masyarakat lebih mementingkan untuk membeli kebutuhan pokok. Ditengah masa endemi ini, diperlukan daya tahan tubuh yang tinggi agar tidak sakit, salah satunya melalui asupan buah dengan kandungan vitamin C yang tinggi. Melalui penanaman jambu kristal dan dipelihara dengan baik di pekarangan rumah masyarakat, diharapkan dapat memenuhi kebutuhan gizi (khususnya vitamin C) secara mandiri tanpa membeli. Dipilihnya Kampung Empel, Desa Mekar Jaya, Kecamatan Banjaran, Kabupaten Bandung karena merupakan daerah yang cocok untuk ditanami jambu kristal dan masyarakatnya mempunyai pekarangan yang luas. Metode yang digunakan dalam kegiatan pengabdian kepada masyarakat (PKM) ini adalah penjajagan, penyuluhan, pendampingan dan evaluasi. Materi yang diberikan saat penyuluhan adalah pemeliharaan tanaman jambu kristal dan manfaatnya untuk kesehatan. Kegiatan yang dilakukan adalah persiapan bibit jambu kristal, penanaman jambu kristal di halaman dan pemeliharaan jambu kristal. Hasil dari kegiatan ini adalah masyarakat lebih mengenal pemeliharaan jambu kristal dan manfaat buah jambu kristal  serta peningkatan minat masyarakat untuk meningkatkan gizi dan daya tahan tubuh melalui konsumsi jambu kristal, mengingat masa pandemi covid saat itu. Kegiatan penyuluhan ini berdampak positif terhadap prospek dan minat untuk menanam jambu kristal di pekarangan rumah.
