Aphids are polyphagous insects commonly found on various plants, including citrus plants. The association between aphids and citrus plants plays a role as pests and vectors of citrus plant diseases, particularly Citrus tristeza virus (CTV). Various aphid species have been reported as CTV vectors, including Aphis gossypii, Toxoptera aurantii, and T. citricidus. So far, no information has been on aphid species associated with citrus plants in Southeast Sulawesi. Therefore, this study aimed to identify aphid species associated with citrus plants. The research method used was observation and collection of aphids found colonizing citrus plants. The collected aphids were then brought to the laboratory for detection using the polymerase chain reaction (PCR) technique. The study results showed that the aphid species associated with citrus plants was Aphis citricidus. The PCR technique successfully detected the genome of aphid vector samples from Konawe and South Konawe (700 bp). This information is a fundamental basis for controlling CTV in mainland Southeast Sulawesi.

2025-07-07T14:11:30+00:00

Biosaka contains elicitor compounds that stimulate the physiological activity of plants, including increased chlorophyll content and enhanced efficiency of assimilate distribution. This study aims to examine the effect of elixitors in biosaka on leaf chlorophyll content and its relationship with the distribution of assimilates in the vegetative growth phase of melon plants. The research was conducted using an experimental method with a non-factorial Complete Random Design (CRD). The single factor in the form of biosaka concentration consists of six levels: B0 = 0 mL L⁻¹, B1 = 10 mL L⁻¹, B2 = 20 mL L⁻¹, B3 = 30 mL L⁻¹, B4 = 40 mL L⁻¹, and B5 = 50 mL L⁻¹. Each treatment was repeated four times, with each repetition consisting of three plants. The results showed that the application of biosaka at various concentrations had no significant effect on all observed parameters. Nevertheless, there is a substantial increase in plant length by up to 93% towards the end of the vegetative phase. A positive correlation was found between plant length and assimilate distribution to the crown (r = 35–47), as well as between leaf area and plant length and assimilate distribution to the crown (r = 36–77). This indicates that the application of biosaka contributes to the increase in physiological activity of plants, through an increase in leaf area that supports the process of photosynthesis and assimilation in the upper part of the plant.

Quail (Coturnix coturnix japonica) is an egg-producing poultry species whose optimal egg production relies on reproductive health, which can be supported by adding herbal supplements to the feed. This study investigated the potential of black cumin meal (BCM) and noni leaf meal (NLM) on the reproductive quality of female quail. Ninety-six heads of quails aged 66 days were maintained for 28 days with the following treatment: T0= Basal Feed (BF); T1= BF + 1% BCM + 3% NLM; T2= BF + 2% BCM + 3% NLM; T2= BF + 2% BCM + 2% NLM; T3= BF + 3% BCM + 1% NLM. Two head quails in each unit were necropsied to observe the parameters of the study, such as: weight and length of the oviduct, oviduct presentation, reproductive organ presentation, ovary weight, number and weight of yellow follicles, and weight of white follicles. The data were analyzed using a completely randomized design (CRD) with four treatments and three replications. The results showed that BCM and NLM supplementation only affected the weight of the oviduct and ovary (P<0.05); otherwise, there was no effect (P>0.05). No additional protein source is responsible for this finding; instead, the antioxidant content of the supplement serves to maintain livestock health. A combination of BCM and NLM can be recommended as a feed supplement at a rate of up to 1-3%.

2025-07-07T14:11:31+00:00

Urban parks serve as areas that support social interaction and enhance the quality of life for the community. These parks feature vegetation that enhances their aesthetic and provides ecological benefits. Vegetation contributes to visitor comfort and improves park accessibility. However, suboptimal vegetation planning can hinger accessibility for certain groups, such as disabilities, elderly, and children. This study aims to analyze the role and impact of vegetation on accessibility in Vatulemo Park. The research begins with observations, spatial analysis using GIS to examine the distribution of vegetation and circulation patterns park. Additionally, a landscape design evaluation is conducted based on Universal Design principles and accessibility standards for green open spaces. The findings indicate that the distribution of vegetation in Vatulemo Park does not fully support accessibility. Shaded areas along circulation paths and jogging tracks are still insufficient, making the park less comfortable for visitors, especially between 10:00 AM and 4:00 PM WITA. Moreover, the lack of vegetation around seating areas and gathering spaces reduces the park's ecological function and user comfort. Therefore, recommendations for improving vegetation placement within the park are necessary to increase greenery along circulation paths and jogging tracks. The selection of plant species should also be adjusted to avoid obstructing visitor activities and comfort. Furthermore, chosen vegetation should not hinder accessibility, and user-friendly pathways should be provided for individuals with special needs. By implementing these strategies, Vatulemo Park is expected to become a more inclusive, comfortable, and ecologically sustainable public space for the residents of Palu City.
