Abstract

Corn cob waste (tumpi jagung) has potential as a livestock feed due to its abundant availability; however, it is characterized by low crude protein content and high crude fiber content, which limits its utilization. Therefore, efforts are needed to reduce its crude fiber content to improve its nutritional value for livestock. This study aimed to evaluate the effect of corn cob fermentation using MA-11 and EM-4 bioactivators on crude fiber (CF), acid detergent fiber (ADF), and neutral detergent fiber (NDF) contents. The study was conducted in February 2025 at the Laboratory of the Faculty of Agriculture, Univet Bantara. The experimental design used was a Completely Randomized Design (CRD) with a one-way pattern, consisting of three treatments and eight replications. The treatments were as follows : 250 g corn cob + 2 g urea + 5 cc molasses; 250 g corn cob + 5 cc MA-11 + 2 g urea + 5 cc molasses; 250 g corn cob + 5 cc EM-4 + 2 g urea + 5 cc molasses. All treatments were incubated for 7 days. The observed variables were crude fiber (CF), ADF, and NDF contents. Data were analyzed using analysis of variance (ANOVA) followed by Duncan’s Multiple Range Test (DMRT). The results showed that fermentation of corn cob waste using MA-11 and EM-4 significantly reduced crude fiber, ADF, and NDF contents. Unfermented corn cob contained CF 6.36%, ADF 39.64%, and NDF 50.59%. Fermentation with MA-11 resulted in CF 4.33%, ADF 33.96%, and NDF 48.33%, whereas fermentation using EM-4 produced CF 3.70%, ADF 32.88%, and NDF 46.78%. The EM-4 bioactivator was more effective in reducing fiber components, with decreases of 0.63% in crude fiber, 1.08% in ADF, and 1.55% in NDF compared to MA-11.

Abstract

The production of shallot varieties is influenced by the adequacy of nutrients and soil conditions. Soil that has low nutrient content requires high nutrient input. Ultisol soil is one of the marginal soils, this soil requires additional nutrients from the right type of manure to increase crop yields. The study aims to determine the type of manure that can increase the yield of Lokananta shallots on ultisol soil. The research location is in Pangkalpinang City, Bangka Belitung Islands Province. The research period is from October 2024 to April 2025. The eksperiment used a Randomized Block Design, consisting of 4 groups based on the size of the bulbs used as seeds. The treatments were 5 types of manure (chicken, cow, goat, swallow, and bat) and control (without additional fertilizer). The parameters observed were plant height, number of leaves, number of shoots, stem diameter, bulb diameter, wet weight of bulbs, dry weight of bulbs, and yield per plot. The harvested bulbs were analyzed for water content, reducing sugar, and essential oils (VOC). The results of the study showed that the best type of manure is that derived from chicken manure. Chicken manure has been proven to be able to increase the number of leaves, number of shoots, and number of plant bulbs, tends to be higher in yield of bulbs per plant. Red onion bulbs have the highest reducing sugar content in the chicken manure treatment, while the lowest water content is found in bat manure.

Abstract

This study aims to analyze the protein content of suckermouth catfish (Pterygoplichthys sp.) egg meal and to evaluate its potential as a fish feed ingredient. Egg meal samples were analyzed using Uv-Vis spectrophotometry with a standard albumin curve approach using linear regression. The analysis showed that the protein content of suckermouth catfish egg flour ranged from 35 to 37%. This value indicates a fairly high protein content, suggesting its potential as an additional protein source in fish feed formulations. In addition, suckermouth catfish are an invasive species that negatively impacts aquatic ecosystems. Therefore, utilizing its eggs as a feed raw material not only provides economic added value but also helps control the population of this invasive species. The use of sapu-sapu fish egg meal can be a sustainable and economical alternative for providing feed raw materials, especially to support fish growth in intensive aquaculture systems.

Abstract

Continuous use of chemical fertilizers hurts soil conditions. The soil hardens quickly, is less able to retain water, and quickly becomes acidic, thus reducing plant productivity. Efforts are needed to use organic fertilizers from agricultural waste and biofertilizers from potential rhizosphere fungi. The purpose of this study was to obtain an effective formulation and combination of organic fertilizers from agricultural waste with 2 species of Rhizosphere fungi isolated from Tana Toraja aromatic rice plants, namely Aspergillus sp and Trichoderma sp, on the growth and production of Tana Toraja aromatic rice plants. This study was designed as a two-factor factorial experiment arranged in a Randomized Block Design. The first factor was three levels: Rhisosphere Fungus C0 = Without Fungus Application, C1 = Rhisosphere Fungus 5 g / liter of water. C2 = Rhisosphere Fungus 10 g / liter of water. The second factor was liquid organic fertilizer/compost from agricultural waste at three levels: K0 = No liquid fertilizer, K1 = 500 ml liquid fertilizer/10 liters of water, and K2 = 1000 ml liquid organic fertilizer/10 liters of water. Nine treatment combinations were replicated thrice, each with two plants, resulting in 54 experimental plots. The results showed that applying Trichoderma and Aspergillus fungi at a dose of 10 g/liter had the best effect. Meanwhile, applying liquid organic fertilizer from cocoa shells and straw at 1000 ml/10 liters of water had the best effect. The best combination/interaction effect was found between the application of 10 g/L rhizosphere fungi and 10 g/L liquid fertilizer, and 1000 ml/L liquid organic fertilizer on the observed components of plant height, number of tillers, number of productive tillers, number of grains/panicle, and panicle length.
