Abstract

Corn is one of the food crops in Indonesia that has great potential to be developed, one of which is Waxy Corn. This type of corn has a high amylopectin content, but its productivity is still relatively low. One effort to increase the productivity of Waxy Corn is through the use of liquid organic fertilizer from tofu waste. This research was conducted on the land of the Jember State Polytechnic in July-October 2024 using a randomized block design with a single treatment, namely the comparison of the concentration of liquid organic fertilizer tofu waste. There are six treatment levels, namely control (0 ml/l), 26 ml/l, 28 ml/l, 30 ml/l, 32 ml/l, and 34 ml/l. The data were analyzed using analysis of variance, and if there was a significant difference, a further test of the smallest significant difference was carried out. The results showed that the treatment of liquid organic fertilizer with a concentration of 34 ml/l had a significant effect on the stem diameter at the age of 21 days after planting and the weight of the cob per sample. The concentration of 30 ml/l affected the cob diameter, while the concentration of 32 ml/l affected the cob weight per plot. The parameters of plant height and biomass weight did not show significant differences.

Abstract

Bovine rumen bacteria consist of diverse microorganisms essential for processing manure, compost, and liquid organic fertilizer, enhancing soil fertility and nutrient availability while suppressing pests and pathogens. These bacteria include cellulose-digesting species such as Bacteroides succinogenes, Ruminococcus flavefaciens, and Ruminococcus albus, which produce cellulase enzymes for organic matter decomposition. Morphologically, cellulolytic bacteria are categorized into coccus forms (Ruminococcus flavefaciens and Ruminococcus albus) and rod forms (Bacteroides succinogenes and Butyrivibrio fibrisolvens), with Gram-positive and Gram-negative cell walls. This study examined the growth and morphology of bovine rumen bacteria in fermented liquid over three weeks. Colony counts increased from 4.75 × 10⁶ CFU/mL in week 1 to 2.92 × 10⁷ CFU/mL in week 2 and 6.2 × 10⁸ CFU/mL in week 3. Colony morphologies included colors (pink, yellow, blue center), sizes (small, medium, large), shapes (circular, irregular), elevations (raised, convex, unbonated), surfaces (smooth, mucoid), and edges (regular, irregular). Predominant bacterial cell shapes were bacillus, with Gram-positive staining. These findings underscore the potential of bovine rumen bacteria in organic waste fermentation and nutrient cycling.

Abstract

Cowpea (Vigna unguiculata L.) is one of the food crops with relatively high protein content, but its production remains relatively low. The applied cultivation technology is still not optimal, resulting in no significant increase in cowpea production. This study aims to determine the effect of applying various concentrations of Plant Growth Promoting Rhizobacteria (PGPR) on the growth and production of cowpea. The research was conducted at the Jember State Polytechnic field from July 2024 to October 2024. The study used a Non-Factorial Randomized Block Design (RBD) with 6 treatments and 4 replications. The treatments consisted of PGPR concentrations of 0 ml/L, 18 ml/L, 29 ml/L, 40 ml/L, and 51 ml/L. The observed variables included plant height, stem diameter, number of sample pods, fresh weight of sample pods, fresh weight of pods per plot, dry weight of sample pods, dry weight of pods per plot, dry seed weight per plot, and weight of 100 seeds per plot. The results showed that the PGPR treatment at a concentration of 51 ml/L significantly affected plant height, dry seed weight of samples, and weight of 100 seeds per plot. This is likely due to the role of PGPR as a biofertilizer and biostimulant. However, there were no significant differences in stem diameter, number of sample pods, fresh weight of sample pods, fresh weight of pods per plot, dry weight of sample pods, dry weight of pods per plot, and dry seed weight per plot.

Abstract

Sistem tanam monokultur yang umum diterapkan petani cenderung menurunkan kestabilan agroekosistem karena meningkatnya risiko serangan hama dan penyakit. Salah satu alternatifnya ialah sistem polikultur yang dapat memperkaya habitat bagi berbagai jenis artropoda, termasuk musuh alami hama. Penelitian ini bertujuan untuk menganalisis keanekaragaman artropoda pada berbagai kombinasi tanam jagung ketan dan kedelai edamame dengan tambahan tanaman border serai dan kemangi. Penelitian dilaksanakan pada empat tipe lahan pertaniandi Kebonsari, Jember, Jawa Timur: 1) monokultur jagung ketan, 2) polikultur jagung ketan-edamame, (3) polikultur jagung ketan-edamame dengan border serai, dan 4) polikultur jagung ketan-edamame dengan border kemangi. Pengambilan sampel dilakukan menggunakan pitfall trap, yellow trap, dan sweep net, sedangkan data dianalisis menggunakan indeks keanekaragaman (H'), kemerataan (E), dan dominasi (C). Hasil menunjukkan bahwa perlakuan polikultur bersamaan dengan border tanaman aromatik terbukti meningkatkan keseimbangan komunitas arthropoda yang menguntungkan. Polikultur kemangi efektif meningkatkan parasitoid, sedangkan polikultur serai lebih optimal dalam meningkatkan predator dan penyerbuk.  The monoculture system commonly practiced by Indonesian farmers tends to reduce agroecosystem stability due to the higher risk of pest and disease. On the other hand, polyculture can provide a more diverse habitat that supports beneficial arthropods, including natural enemies. This study aimed to analyze the diversity of arthropods in various planting combinations of waxy maize and edamame with additional border plants of lemongrass and basil. The research was conducted from June to September 2024 in Kebonsari, Jember, East Java, using four treatments: (1) maize monoculture, (2) maize–edamame polyculture, (3) maize–edamame polyculture with lemongrass borders, and (4) maize–edamame polyculture with basil borders. Arthropod sampling was carried out using pitfall traps, yellow traps, and sweep nets, and data were analyzed using the diversity index (H'), evenness index (E), and dominance index (C). The results showed that the polyculture combined with aromatic plants as a border effectively enhanced the balance of beneficial arthropod communities. Polyculture with basil effective in increasing parasitoid abundance, while polyculture with lemongrass is more optimal in increasing predators and pollinators.
