Abstract

Generative propagation of Mucuna bracteata is hindered by its thick seed coat, which causes seed dormancy. This study aimed at evaluating viability and vigor of M. bracteata due to pre-treatments. A completely randomized design was used to test four pre-treatments: no treatment (Kon), soaking in warm water (50°C) for 2 hours (AHA), soaking in plain water for 24 hours (ABI), and scarification on cotyledon side (DLU). Variables measured were germination percentage, maximum growth potential (MGP), germination rate, vigor index (VI), uniformity of germination (UG), and growth speed (GS). Germination percentage and MGP data were analyzed using descriptive statistics, while germination rate, VI, UG, and GS data were analyzed using analysis of variance. The results showed that pre-treatment of M. bracteata seeds increased germination percentage, reaching 98.66% on day 3, and MGP reached 98.0%. Likewise, there was a highly significant increase (p<0.001) in germination rate (7–11 days), VI (15.99–91.99%), UG (18.66–97.33%), and GS (14.33–25.83%/day). The highest scores for all variables were found in DLU treatment. It is concluded that soaking seeds in warm water, plain water, or scarifying the seed coat improves viability and vigor of M. bracteata seeds, with DLU being the best technique. Keywords: dormancy, Mucuna bracteata, seed viability, seedling vigor

Abstract

The Free Nutritious Meal Program (Program Makan Bergizi Gratis/MBG) is a government effort to improve students' nutrition in schools. While the program helps students eat better, it also generates organic waste every day, including food scraps and kitchen leftovers. If not managed, this waste can harm the environment. This study examines how MBG waste can be converted into compost, an environmentally friendly fertilizer. The research took place from June to October 2025 in three public junior high schools in Surakarta City, Central Java, Indonesia, involving 540 students from grades 7 to 9. The study focused on food leftovers from MBG meals and included waste sampling, sorting, composting, and lab analysis. Results showed that most of the waste came from carbohydrates such as rice and pasta (about 35–50%), followed by vegetables (about 14–25%). On average, each student produced 115.78 grams of food waste per day, which could add up to about 1,169.8 tons of food waste daily from junior high school students across Indonesia. The compost made from MBG leftovers had 1.19% N, 2.42% P₂O₅, and 0.24% K₂O, meeting SNI 7763:2024 standards. It has high organic matter content, neutral pH, and adequate availability of micronutrients. In terms of safety, the microbiological contamination test results indicated excellent quality. Both Escherichia coli and Salmonella sp. were detected at levels below 3 MPN/g. These findings show that MBG waste can be turned into organic fertilizer, helping schools manage waste and support sustainable agriculture. Keywords: composting, environmental management, organic waste, school meal program, sustainable agriculture

Abstract

An increase in free radicals in the body can result from continuous exposure to heavy metals such as lead (Pb). This condition can result in oxidative stress due to damage to cellular structures, including the lipid bilayer membrane, cellular proteins, and DNA. One approach to reduce such damage is the administration of exogenous plant-derived antioxidants, including kabau. This study aimed to determine the chemical compound profile contained in kabau pod peel extract and to evaluate its effects on erythrocytes and leukocytes in lead-induced mice. GC-MS analysis was conducted to identify the types of compounds present in the extract. An in vivo experiment was conducted with six groups: three control and three treatment groups. The GC-MS results showed that the abundant antioxidant compounds were 2,3-butanediol and 4H-pyran-4-one, 2,3-dihydro-3,5-dihydroxy-6-methyl. The in vivo results indicated that administration of kabau pod peel extract did not significantly affect leukocyte and erythrocyte counts in the blood of mice exposed to lead acetate. Keywords: antioxidant, archidendron, blood cell, GC-MS, kabau

Abstract

The growth and yield of maize (Zea mays L.) are constrained by abiotic and biotic stresses, necessitating sustainable approaches to improve crop performance. Cnidoscolus aconitifolius leaf extract, rich in bioactive phytochemicals, has potential as a natural biostimulant for enhancing maize growth. This study aimed to evaluate the effects of C. aconitifolius leaf extract on the growth of maize. The experiment was conducted using a two-factor Completely Randomized Design (CRD), with solvent type (aqueous, ethanol, methanol, and butanol) and extract concentration (0, 25, 50, and 100 mg/L) as the experimental factors. The results showed that maize treated with C. aconitifolius leaf extract prepared using 70% ethanol at 50 mg/L exhibited the highest shoot fresh weight (455.0 g), shoot dry weight (319.1 g), and 100-grain weight (40.2 g). The 70% ethanol extract applied at 25 mg/L produced the greatest leaf number (14) and root fresh weight (202.5 g). In contrast, the highest plant height (199.4 cm) was recorded in plants treated with the 70% methanol extract at 50 mg/L. The greatest root dry weight (102.5 g) was observed in the control treatment, whereas the highest total number of grains per cob (563.7) was obtained with the aqueous extract applied at 25 mg/L. Keywords: biostimulant, chaya, maize, plant extract

Abstract

Broiler chicken production requires appropriate environmental control to maintain productivity and animal welfare. This study evaluated the effect of implementing an IoT-based cyber-physical system on microclimate stability and broiler chicken performance under semi-industrial conditions. A total of 4,200 CP-707 broiler chickens were reared for 33 days in a closed-house facility using a before-and-after design that compared a non-system controller with an IoT-based cyber-physical system that integrated environmental sensors, a programmable logic controller, and cloud-based monitoring. This system maintained stable environmental conditions and reduced deviations from standard operating procedures. Average house temperature and feed conversion ratio (FCR) did not differ significantly before and after implementation (p = 0.080 and p = 0.645, respectively). However, mortality rates decreased significantly from 5.09% to 2.36% (p = 0.005), and body weight increased from 846.29 g to 895.43 g (p < 0.001). The Performance Index (PI) also increased, although the difference was not statistically significant (p = 0.088). These findings indicate that the IoT-based cyber-physical system improves the survival and growth of broiler chickens whilst maintaining feed efficiency through more stable environmental control. This system offers a practical and adaptable approach to improving productivity, sustainability, and animal welfare within modern closed-house broiler chicken production systems.

Abstract

Excessive and inefficient use of nitrogen (N), phosphorus (P), and potassium (K) fertilizers remains a major issue in agricultural systems, often leading to low nutrient use efficiency and environmental losses. Slow-release fertilizers in different forms, such as tablets and granules, combined with coating technology, represent a potential strategy to regulate nutrient availability and improve release efficiency. This study aimed to evaluate the release patterns of N (including NH4+, NO3-, and total N), P, and K from coated and uncoated slow-release fertilizers in tablet and granule forms. The experiment, conducted at the Laboratory of Soil Chemistry and Plant Nutrition, Universitas Padjadjaran, used a Completely Randomized Design (CRD) with four treatments and five replications. The treatments included coated tablet fertilizer (A), uncoated tablet fertilizer (B), coated granule fertilizer (C), and uncoated granule fertilizer (D), incubated for 10 weeks under laboratory conditions. The key implication of these results is that uncoated tablet fertilizer (B) delivered the most balanced nutrient release, with total N, P, and K releases of 80.07%, 70.87%, and 88.22%, respectively, suggesting it may offer a practical solution for improving nutrient efficiency while minimizing losses. In contrast, coated tablet fertilizer (A) showed the slowest release, while uncoated granule fertilizer (D) had the fastest. These findings highlight that manipulating fertilizer form and coating application play a decisive role in optimizing nutrient release kinetics and improving synchronization in slow-release fertilizer systems, offering a targeted approach to address agricultural nutrient management challenges.

Abstract

Soybeans (Glycine max L.) are a highly nutritious crop and serve as the primary raw material for various food products. One approach to increasing soybean productivity involves applying organic matter to marginal soils, such as Inceptisol. The study aimed to determine the effect of black soldier fly (BSF) frass application on improving the growth, yield, and NPK nutrient uptake of soybean plants in Inceptisol soil, as well as to identify the optimal BSF frass application rate that yields the best growth, yield, and NPK nutrient uptake. The study employed a Completely Randomized Design (CRD) with four treatment levels of BSF frass application rates: 0, 5, 7.5, and 10 metric tons of BSF frass per hectare. Data were analyzed using analysis of variance (ANOVA) followed by Duncan’s New Multiple Range Test (DNMRT) at the 5% significance level. The observed parameters were plant height, number of pods, percentage of filled pods, seed weight per plant, effective root nodules, and NPK nutrient uptake by soybean plants. The results showed that the application of BSF frass fertilizer increased plant height, the number of pods, the percentage of filled pods, seed weight per plant, effective root nodules, and NPK nutrient uptake by soybean plants. The highest soybean yield was achieved with a BSF frass application rate of 5 t/ha, resulting in a seed weight per plant of 13.11 g—equivalent to 1.64 t/ha—and nutrient uptake of N, P, and K increased by 42.52%, 25%, and 2.90%, respectively.

Abstract

Vehicular activity along urban toll road corridors contributes to particulate matter emissions that degrade air quality and increase public health risks, particularly respiratory and cardiovascular disorders. Roadside greenbelts are considered a nature-based solution for reducing airborne particles; however, comparative evaluations of roadside tree species for PM2.5 and PM10 mitigation remain limited. This study evaluated the reduction performance of three commonly planted roadside tree species, namely Lagerstroemia speciosa, Gmelina arborea, and Mimusops elengi, along the Jagorawi Toll Road. Particulate concentrations were measured in three vegetated plots and one non-vegetated control plot on 26, 28, and 30 April 2025 using calibrated Dienmern DM72B digital air quality detectors. Measurements were conducted simultaneously at 0, 10, and 30 m sampling points, with the 0 m point located at the first roadside tree row, approximately 5 m from the road edge. Leaf Area Index (LAI), leaf particulate retention capacity, microclimate, and traffic volume were also recorded. Vegetated plots reduced PM2.5 and PM10 concentrations by 30.82% and 29.23% on average, respectively, compared with the control at the same sampling distances. The plot dominated by M. elengi showed the largest average reduction, supported by the highest LAI value (2.1639) and leaf retention capacity (0.20 mg/cm²). These findings indicate that dense, high-LAI roadside tree canopies can improve PM2.5 and PM10 mitigation. However, species effects should be interpreted together with planting structure and site conditions. This study supports prioritizing high-LAI and dense-canopy species in roadside greenbelt planning.

Abstract

This study aimed to simulate the population dynamics projection of beef cattle in smallholder farms by comparing the forced sale and capacity expansion scenarios over a 10-year period. The research was conducted through a survey involving 60 cattle farmers (30 semi-intensive and 30 intensive systems) in Gelumbang District, Muara Enim Regency. Population dynamic modeling was analyzed using the Dynamics System approach with the Cohort Component Method to project the population from 2025 to 2034. The results showed that semi-intensive farmers were oriented towards breeding for asset accumulation, while intensive farmers focused on rapid capital turnover. Projection simulations proved that the existing scenario (forced sell) led to a stagnation in business scale, where the semi-intensive population was constrained to 11 to 12 heads and the intensive to 5 to 6 heads over the 10 years (Figure 1). In contrast, implementing the capacity expansion scenario through delayed sales, capital reinvestment, and partnership schemes triggered a progressive organic population surge, reaching 151 heads in the semi-intensive system and 22 heads in the intensive system by the 10th year (Figure 2). It can be concluded that the traditional mindset of treating cattle as reactive savings is the main cause of stagnation. Population growth strategies require a sociocultural transformation through capacity planning, education, and the institutionalization of partnership systems. Keywords: barn capacity planning, beef cattle, cohort component method, forced sell, population projection
