Abstract

Andrographis paniculata (sambiloto), with its active compound, andrographolide, shows potential as a feed additive to enhance broiler chicken performance. This study aimed to evaluate the potential of Sambiloto as a natural feed additive on broiler performance. The materials used included 50 male broilers aged 14 days, commercial feed, and Sambiloto powder. The research employed an experimental method with a Completely Randomized Design (CRD). There were 5 treatments, each replicated 4 times: P0 (negative control without Sambiloto), P1 (positive control with vitamins without Sambiloto), P2 (5% Sambiloto), P3 (10% Sambiloto), and P4 (15% Sambiloto). Treatments were administered for 21 days. The observed variables were production performance, including final body weight, feed conversion ratio (FCR), livability percentage, and performance index (PI). Data were analyzed using Analysis of Variance (ANOVA) followed by Least Significant Difference (LSD) to determine differences between treatments. Research results showed that supplementing sambiloto in feed had a highly significant effect (P0,01) on final body weight and the PI of broilers, but no significant effect (P0,05) on the FCR and percentage of live chickens. The highest average final body weight was observed in the control group at 1.6 kg. The highest average PI was found in the 5% sambiloto treatment at 613.11. The best average FCR was recorded in the 5% sambiloto treatment at 1.20. The highest average percentage of live chickens (100%) was achieved in the control, 5% sambiloto, and 10% sambiloto groups. In conclusion, Sambiloto leaves have the potential to enhance broiler performance.

Abstract

Nyamplung (Calophyllum inophyllum L.) is a coastal plant species that plays an important ecological role in protecting coastal areas from abrasion, reduce the impact of sea winds, and maintain the stability of coastal environments, while the tree is economically potential as vegetable oil sources for biodiesel. In Padang Pariaman Regency, Nyamplung is also knows as Pinago, the trees are found growing in the coastal areas, both naturally and through planting, but it is still remain unknown the current spatial distribution and the local habitat conditions. This study aimed to investigate the spatial distribution and habitat characteristics of Nyamplung in the coastal area of Padang Pariaman Regency. Field observations were conducted for recording coordinates location of each Nyamplung tree, measuring the diameter at breast height (DBH) and canopy cover, and determining habitat characteristics. The spatial distribution  was analyzed using ArcGIS, while the habitat conditions and the population structure were analyzed in terms of linear regression. The results showed that Nyamplung was distributed partly or clustered at three specific site in  the coastline. Most of the site was sandy habitat with very thin layer of top soil and the trees were moslty exposed to full sunlight. The trees were varied in size, ranged from 2-62 cm dbh, with crown cover ranged from 5-600 m2, and these two variables were positively correlated. This study showed a limited number of Nyamplung trees in the coastal of Padang Pariaman, with less damage of community to canopy. Planting of Nyamplung in this area for a wider positive impact.

Abstract

Tomato (Solanum lycopersicum L.) is a high-value horticultural commodity, yet its productivity in Indonesia tends to fluctuate. Efforts to increase production can be made by improving soil physical and chemical properties using soil conditioners. Humic acid enhances nutrient availability but requires a carrier, such as zeolite, for optimal distribution. This study aimed to determine the most effective dosage combination of humic acid and zeolite on the vegetative growth of the tomato variety. Servo F1. The research was conducted in an open field in Purwakarta, West Java, from April to August 2025. A single-factor Randomized Complete Block Design (RCBD) was used with 6 treatments and 4 replications, resulting in 24 experimental units. The treatments consisted of combinations of humic acid (25, 50, 75 L/ha) and zeolite (500, 750 kg/ha). Parameters observed included plant height, leaf number, and stem diameter at 14, 21, 28, and 35 days after transplanting (DAT). Data were analyzed using ANOVA, followed by DMRT, at ? = 5%. The results showed that the combination of 50 L/ha humic acid and 750 kg/ha zeolite produced the highest values for all observed parameters. At 35 DAT, Treatment the combination of 50 L/ha humic acid and 750 kg/ha zeolite resulted in plant height (109.76 cm), leaf number (150.50), and stem diameter (10.86 mm). It is concluded that the combination of 50 L/ha humic acid and 750 kg/ha zeolite effectively enhances the vegetative growth of the tomato variety. Servo F1 is recommended as a soil amendment.

Abstract

Urban green open spaces (RTH) provide critical shading and cooling services, yet many tropical cities like Palu have suboptimal planting designs. This study evaluated tree species, planting distance, and spatial patterns in Vatulemo Park (20,000 m²) using a survey method. Planting distances (n=34 trees), canopy overlap, and air temperature under shade were measured at 13:00 local time. Pearson correlation analysis was performed. Dominant species were Samanea saman (spacing 25 m) and Terminalia mantaly (spacing 4 m). Canopy overlap occurred only at 4 m spacing. Under-canopy temperatures were 29.3°C (25 m) and 30.4°C (4 m). Correlation was very strong (R = 0.98, p 0.01). Planting pattern followed row arrangement, compliant with Regulation No. 5/PRT/M/2008. However, species richness (26 taxa) is far below the recommended 150. Planting distance significantly affects shading effectiveness. Vatulemo Park requires reduced spacing (4–6 m), canopy overlap, and increased species diversity to optimize thermal comfort.

Abstract

Snake fruit (Salacca zalacca) is a local commodity with high perishability, necessitating product diversification. This study aimed to evaluate the effect of carrageenan concentrations (0%, 3%, 5%, 7%, 9%) on the physicochemical (reducing sugar content, L*a*b* color, tensile strength) and organoleptic (taste, overall) properties of snake fruit jenang dodol. A completely randomized design (CRD) with 5 treatments and 3 replicates was applied. Physicochemical data were analyzed using ANOVA (?=0.05) followed by Duncan’s test, while organoleptic data were analyzed using the Friedman test. Results showed that the addition of carrageenan had no significant effect on any parameter (p0.05). The highest reducing sugar content (6.49%), lightness (49.90), tensile strength (0.2873 N), and the highest preference scores for taste (1.80) and overall (2.10) were all obtained in the control treatment (0% carrageenan). It is concluded that carrageenan up to 9% does not improve the physicochemical or sensory quality of snake fruit jenang dodol.

Abstract

Foot and Mouth Disease (FMD) and Lumpy Skin Disease (LSD) threaten dairy cattle in Indonesia, causing major economic losses. Evaluation of disease management at the cooperative level remains limited. This study evaluated the FMD and LSD management system at Koperasi Agro Niaga Jabung Syariah, East Java, focusing on detection, isolation, treatment, vaccination, biosecurity, and socioeconomic impacts. A descriptive qualitative case study was conducted from September to November 2023. Data were collected from 24 key informants through interviews, observation, and document analysis. Quantitative data were analyzed descriptively. Among 245 dairy cattle, prevalence was 0.4% for FMD and 5.7% for LSD. The recovery rate was 100% with zero mortality. Vaccination coverage was high (FMD: 92.4%; LSD: 98.9%), and response time was 24 hours. However, the biosecurity score was only 32%, and 50% of farmers lacked isolation facilities. Economic losses reached IDR 6.7–9.9 million (FMD) and IDR 5.4–8.7 million (LSD) per case. Milk production dropped 40–75%. Psychological distress affected 87.5% of farmers, and 25% considered exiting the business.  Rapid detection, multi-stakeholder coordination, integrated conventional-herbal treatment, and mass vaccination led to successful outcomes. However, weak biosecurity and inadequate isolation remain critical vulnerabilities. Strengthening biosecurity, farmer education, and psychological support is urgently needed.

Abstract

Annual market demand for broccoli (Brassica oleracea var. italica) continues to rise. Nevertheless, this increasing trend has not been matched by adequate production quality and quantity, which remain relatively low, thereby necessitating improved cultivation techniques. Currently, broccoli farming is still highly dependent on inorganic fertilizers to support optimal plant growth. Consequently, incorporating organic fertilizers is essential to minimize this reliance. This study aimed to evaluate the effects of applying eco-enzyme to reduce nitrogen fertilizer rates on broccoli yield and quality. The experiment was conducted in Tulungrejo, Bumiaji, Batu City, East Java, from May to July 2024. A randomized complete block design (RCBD) with factorial arrangement was employed, consisting of two factors: eco-enzyme concentrations (0, 15, 30, and 45 ml L?¹) and synthetic N fertilizer rates (0%, 33%, 66%, 100%, and 133% of the recommended dose of 300 kg ha?¹). The results revealed a significant interaction between eco-enzyme concentration and synthetic N fertilizer rate. The application of 30 ml L?¹ eco-enzyme combined with a 66% reduction in inorganic N fertilizer notably enhanced leaf area (4.26%), flower diameter (18.48%), total fresh weight (50.14%), and edible fresh weight (43.82%) compared to the control. These findings suggest that eco-enzymes can effectively reduce dependence on inorganic nitrogen fertilizers in broccoli cultivation.

Abstract

Sugarcane productivity in Sidomulyo Village, Blitar Regency, remains suboptimal despite the village's strategic role as a supply center for the sugar industry. This study aimed to analyze the factors influencing sugarcane production and to determine the partial and simultaneous effects of capital, labor, land area, seeds, fertilizer, and herbicide on production. A quantitative descriptive method with a survey approach was employed, involving 50 respondents selected through purposive sampling. Data were analyzed using multiple linear regression with SPSS version 25. The results of the simultaneous test (F-test) indicate that all independent variables collectively have a significant effect on sugarcane production (F = 61.281; p = 0.000; R² = 0.895), explaining 89.5% of the variation in production. Partially (t-test), labor (p = 0.015), land area (p = 0.000), seeds (p = 0.000), and fertilizer (p = 0.006) have a significant positive effect, while herbicide has a significant negative effect (p = 0.000; coefficient = -0.420). Capital (p = 0.052; coefficient = -0.158) does not have a significant effect at ? = 0.05. The study concludes that to increase sugarcane productivity, farmers should optimize the use of labor, land, seeds, and fertilizer, while reducing excessive herbicide application. Future research is recommended to include variables such as irrigation, technology adoption, and access to credit.

Abstract

This study aims to analyze the influence of price perception, packaging, and taste on purchasing decisions for jackfruit chips at Dapur SiMbok, a Micro, Small, and Medium Enterprise (MSME) in Blitar Regency, Indonesia. Employing a quantitative descriptive approach with 68 respondents selected through purposive sampling, data were collected via questionnaires and analyzed using multiple linear regression. The findings reveal that simultaneously, all three variables significantly influence purchasing decisions (F = 38.196; sig. 0.000). Partially, price (t = 4.267; sig. 0.000), packaging (t = 3.522; sig. 0.001), and taste (t = 5.665; sig. 0.000) each exert a positive and significant effect. Taste emerges as the dominant factor (? = 0.475), surpassing price (? = 0.345) and packaging (? = 0.281). This research offers practical implications for snack MSMEs, encouraging them to prioritize taste innovation as a core marketing strategy.
