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 key coastal species with both ecologyl and economic importance. The tree, is highly recommended for coastal zone restoration, but availability of the seeds and seedlings is less known.This study aimed to investigate flowering/fruiting phenology as well as natural regeneration availability across different in coastal zone of  Padang Pariaman Regency. Weekly phenological observations and regeneration stock measurement were conducted from September to December 2025i, with 34 observed trees in the sites that ranged from ;ow to high land use level. Results showed that most trees were found flowering in September, but it was declined following the increasing of fruiting event at mid to end of October and number of the fruiting trees were declined until end of December. These flowering and fruiting phenology among the landuse types showed a similar pattern with only little variation. In general 0.12 seedlings/m², while tourism areas showed the lowest 0.03 seedlings/m² in the highest disturbed. And is was negatively correlated with distance fron the mother tree(p0.05). This study a range of flowering and fruiting phenology in Padang Pariaman Coastal areas with small variation of the phenology between landuse types, as well as variation in regeneration stock of C. inophyllum across the areas.

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.
