Abstract

This study aimed to evaluate the effect of organic fertilizer modification with the addition of Trichoderma sp. on the growth and yield of cauliflower. A Randomized Blok Design (RAK) with five treatments and four replications. The research was conducted from May to November 2024 on the land of Pondok Pesantren Bakti Bapak Emak, Bareng, Jombang. The results showed that; (a) The use of modified organic fertilizer and Trichoderma had a significant effect on cauliflower plant growth (plant height, number of leaves, and root dry weight). The K3 treatment (Nutrizim Granule Organic Fertilizer + Trichoderma) showed better results for cauliflower growth, with plant height reaching approximately 44,25 cm at 6 weeks after planting and producing an average of 21,15. (b) The treatments tested did not have a significant effect on yield parameters. However, field observations indicate that the modified organic fertilizer with added Trichoderma produced better quality cauliflowers, characterized by denser (more compact) curds, a clean yellowish-white color, and overall improved appearance.

Abstract

This study investigates the use of cocopeat as an eco-friendly planting medium, combined with NPK fertilizer and eco enzyme, to enhance the growth of microgreen water spinach. Cocopeat improves soil moisture and aeration, while NPK provides essential nutrients, and eco enzyme promotes microbial activity and root health. The experiment tested varying doses of NPK and eco enzyme in cocopeat, measuring plant height, leaf count, Vitamin A content, and sprout percentage. Results showed no interaction between NPK and eco enzyme treatments. The NPK solution in cocopeat (M2) yielded the highest growth values, while the control (M0) had the lowest. However, excessive NPK inhibited kale microgreen growth. Conversely, eco enzyme application alone did not significantly improve growth or quality. This research highlights cocopeat's potential as a sustainable medium but suggests careful NPK dosage to avoid growth suppression. While eco enzyme showed no direct impact, further studies could explore its role in nutrient absorption. The findings support eco-friendly cultivation techniques and offer insights into boosting Vitamin A in microgreen kale, contributing to sustainable agriculture and nutritional enhancement.

Abstract

In order to reduce the use of inorganic pesticides which have been proven to pollute the environment and endanger consumers, it is necessary to develop pesticides from plant materials. This study aims to obtain and determine the effect of bintaro plant extract on the development of grower worm (Spodoptera litura). The treatments consisted of 4 combinations of bintaro organs (leaves, bark, fruit flesh, and seeds) and 5 combinations of extract concentrations (2.5%, 5.0%, 7.5%, 10.0%, and 12.5%) so that there are 20 combinations and one control is repeated three times. This research was conducted at the Merdeka University Surabaya laboratory from April to May 2020 using a Completely Randomized Design (CRD). The results showed that the extract of the bintaro plant had no significant effect on the instar development of the grower worm (Spodoptera litura). Bintaro plant extract had a significant effect on the mortality of grower worm (Spodoptera litura) on days 15 to 20, while on the development of life it had a significant effect on days 12 to 20.

Abstract

This study aimed to analyze the effect of planting media composition and liquid organic fertilizer (LOF) concentration from tofu wastewater on the growth and yield of pagoda mustard greens using the verticulture method. The research was conducted in Gunung Sekar, Sampang, East Java, from December 2023 to February 2024. A factorial Randomized Complete Block Design (RCBD) was used with two factors and three replications. The first factor was planting media composition (soil, compost, goat manure) in four ratios: M0 (1:1:1), M1 (1:1:2), M2 (1:2:3), and M3 (2:1:1). The second factor was LOF concentration (0%, 10%, 20%, 30%). Data were analyzed using ANOVA and followed by the Honestly Significant Difference (HSD) test at a 5% significance level. Results showed that the combination of soil+compost+goat manure (1:1:2) with 10% LOF produced the highest fresh weight. Quadratic regression analysis revealed the relationship between tofu wastewater concentration and plant weight (Y = -112.5x² + 29.028x + 23.903, R² = 0.905), with an optimal concentration of 13%.

Abstract

This study aimed to diagnose the causes of seedling mortality in Cavendish banana (Musa acuminata L.) at PT Great Giant Pineapple Nursery. Clinical symptoms observed included leaf wilting, root rot, and blackened corms, primarily under high-humidity conditions. Laboratory isolation and morphological identification confirmed four fungal pathogens as the primary etiological agents: Heart rot (Phytophthora sp.), Aspergillus rot (Aspergillus sp.), fruit rot (Rhizopus sp.), and damping-off (Pythium sp.). Phytophthora sp. was particularly aggressive, causing severe vascular necrosis. Environmental factors such as excessive moisture, poor drainage, and contaminated nursery substrates were found to exacerbate disease incidence. The findings underscore the need for improved nursery management, including strict sanitation, optimized irrigation, and preventive fungicide applications. Recommendations also include the use of disease-free planting materials and enhanced ventilation to reduce fungal proliferation. Implementing these measures can significantly decrease seedling mortality and improve the production of healthy Cavendish banana plants.

Abstract

Microgreens, the nutrient-packed young seedlings of vegetables and cereals, have emerged as a promising alternative feed source in animal husbandry. This study evaluates the efficacy of corn microgreens as poultry feed compared to conventional dried corn in village chicken production. Using a randomized complete block design, twenty 2-month-old village chickens (average initial weight: 750g) were divided into two groups: one fed with dried corn (control) and another with corn microgreens (treatment). Growth performance was assessed through weekly measurements of body weight, body length, and wing length over a 4-week period. Results indicated significant improvements (p<0.05) in all growth parameters for the microgreen-fed group. The treatment group showed 18% greater weight gain, 12% increased body length, and 15% longer wing development compared to controls. These enhancements are attributed to the higher concentrations of essential nutrients, particularly proteins (23% higher) and antioxidants (40% higher), in corn microgreens versus mature corn. The study demonstrates that corn microgreens can serve as a superior feed alternative, potentially reducing reliance on conventional feeds while improving poultry growth rates. These findings offer valuable insights for small-scale poultry farmers seeking cost-effective, nutrient-dense feeding strategies.

Abstract

Manure is an organic fertilizer with adequate nutrients to enhance soil quality and support plant growth. In Sebalong Village, Pasuruan, cow dung is used directly without processing, reducing its effectiveness. This study aims to evaluate different manure processing methods to optimize its use. Conducted in Sebalong Village (October–December 2024), the research employed a Completely Randomized Design (CRD) with four treatments and four replications: Method 1 (Aerobic composting with tarpaulin), Method 2 (Aerobic composting burned + composter), Method 3 (Anaerobic composting + composter + EM4), and Method 4 (Anaerobic composting burned + composter + EM4). Parameters measured included temperature, humidity, pH, and nutrient content (N, P, K, organic C). Results showed that composting methods significantly affected compost quality. Method 4 (anaerobic composting with burning, composter, and EM4) yielded the best results, with organic C (18.66%), BO (32.10%), C/N ratio (7.40), N (2.52%), P (2.42%), and K (2.48%). This method proved most effective in enhancing nutrient levels, suggesting its potential for optimal organic fertilizer production in Sebalong Village.

Abstract

Shallots (Allium ascalonicum L.) are a high-value horticultural commodity with increasing demand, but their production is hampered by shrinking land and excessive use of inorganic fertilizers. Research is needed to find sustainable solutions for yield improvement. This study aimed to determine the most optimal planting media composition and banana tree waste POC (organic liquid fertilizer) concentration for shallot (Allium ascalonicum L.) growth. The study was conducted from July to September 2024 in Sidomukti Village, Bungah District, Gresik Regency. The method applied was a factorial experiment with a Randomized Block Design (RBD) consisting of two factors, with each treatment repeated three times, totaling 36 plants with three samples for each treatment combination. Data analysis utilized analysis of variance (ANOVA), followed by an HSD test at a 5% significance level if ANOVA showed significant results. The study revealed a significant interaction regarding plant height at 42 days after planting (DAP) and shoot dry weight. The planting media composition of soil + vermicompost + goat manure (1:2:2) significantly affected plant height at 56 DAP. A POC concentration of 30% significantly influenced the number of leaves from 21 DAP to 35 DAP.

Abstract

The rapid advancement of remote sensing technology and Geographic Information Systems (GIS) has substantially enhanced the accuracy, efficiency, and comprehensiveness of spatial data acquisition and analysis. This study investigates land-use patterns within a selected area of Belayung Baru Village, Kertak Hanyar District, Banjar Regency, South Kalimantan, employing high-resolution drone imagery to generate detailed spatial information. A multirotor drone-based mapping survey was utilized, with data processed through Agisoft Metashape and ArcGIS to produce orthomosaic images and thematic land-use maps. The results reveal that the study area encompasses approximately 93.74 hectares, predominantly consisting of rice fields (65.86 ha), residential zones (17.15 ha), and wetlands (6.69 ha). Visual interpretation of drone imagery demonstrates pronounced seasonal contrasts between rice fields and wetlands in terms of spectral tone, texture, and spatial pattern. Furthermore, the dynamic hydrological conditions of the wetland ecosystem substantially influence local agricultural cycles, restricting cultivation to the dry season when the water table recedes. Overall, this study underscores the effectiveness of drone-based geospatial technology in delivering precise spatial mapping outputs that support sustainable land-use management and planning.
