THE EFFECT OF COMBINATION SLUDGE, HUSK CHARCOAL, COMPOST, AND NPK FERTILIZER ON THE GROWTH SWEET CORN
No full textThe spice and seasoning industry produce sludge waste that has the potential to pollute the environment if not managed properly. This waste contains nutrients and organic matter, making it a potential soil conditioner for sweet corn cultivation; however, its use must be combined with other materials such as rice husk charcoal and compost. This study aims to determine the effectiveness of combining sludge, compost, husk charcoal, and NPK fertilizer on the growth and productivity of sweet corn. This study was conducted at the Cikabayan Experimental Farm using a Randomized Block Design (RBD) with five levels of sludge application: (1) 100% sludge (S1H2), (2) 75% sludge (S2H2), (3) 50% sludge (S3H2), all treatments were combined with husk charcoal (75%), compost (30%), NPK fertilizer (75%), urea (100%), (4) PB (NPK 100%), and (5) Control (no treatment). Each treatment was repeated three times, resulting in 15 experimental units. The results showed that the S2H2 treatment yielded the best results for all plant growth parameters, such as plant height, stem diameter, and all generative parameters. The S1H2 combination yielded the best results for soil chemical and biological characteristics, including pH, organic carbon, total nitrogen, total microbes, and total fungi. The S1H2 combination also yielded the best results for corn plant productivity at 5.30 tons/ha. The combination of organic matter and NPK fertilizer application is highly efficient as it reduces NPK fertilizer use by 25%

THE EFFECT OF BROILER CHICKEN MEAT MARINATION USING CUCUMBER SOLUTION (CUCUMIS SATIVUS L) ON MEAT QUALITY
No full textMost of the causes of meat spoilage are due to poor handling, which provides opportunities for contamination or growth of spoilage-causing microbes that can affect the quality and shelf life of the carcass. Marination becomes a strategic step in maintaining the quality of meat and extending its shelf life. To maintain the quality of the carcass during storage, the addition of cucumbers containing antibacterial compounds is necessary to inhibit the growth of spoilage-causing microorganisms. The purpose of this study is to determine the effect of soaking chicken meat in cucumber solution on the quality of chicken meat during the storage process. The method used in this study is a Completely Randomized Design (CRD) with four treatments and four replications, differing in storage duration at room temperature (0, 3, 6, and 9 hours). The data obtained were analyzed using the Analysis of Variance (ANOVA) test. If a significant treatment effect is found, it is followed by a comparison test using Duncan’s Multiple Range Test (DMRT) at a 5% significance level. Based on the statistical test, the chemical quality of pH and moisture content, as well as the physical quality of cooking loss, still show values within the standard feasibility range. The results of the ANOVA test show a significant difference in pH and cooking loss values, but no significant effect on moisture content values.

No full textThis study aims to determine the effect of goat feces compost residue and plant growth regulators (PGR) on the growth and yield of spring onions (Allium fistulosum L.) in dry land. The study was conducted in February-April 2023 at the Dry Land Study Center, Timor University and the Laboratory of the Faculty of Agriculture, Timor University, North Central Timor Regency, East Nusa Tenggara. The study used a factorial randomized block design with two factors: first, residues of various doses of goat feces compost (control, 20 tons/ha, 30 tons/ha, 40 tons/ha), and second, shallot PGR with three concentrations (100 ml/L, 200 ml/L, 300 ml/L). The parameters observed included environmental conditions, growth, and plant yield. The results showed an interaction between goat feces compost residue and PGR on the number of leaves two weeks after planting and plant weight per plot. The application of goat feces compost fertilizer with a higher dose (20-40 tons/ha) increased plant growth, including the number of leaves, root length, root volume, and harvest index. Meanwhile, the application of shallot PGR significantly affected the harvest index, although it did not significantly affect other parameters. The right dose and concentration of both treatments can increase the yield of spring onions. This study shows that the right combination of goat feces compost fertilizer and PGR can increase plant yields, especially in dry land conditions
