Abstract

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.

Abstract

Vibrio sp. is an opportunistic pathogenic bacterium that causes vibriosis in fish, shrimp, and seaweed. The use of synthetic antibiotics is everyday; however, resistance is difficult to prevent. The advantages of using natural antibiotics include their availability, environmental friendliness, and cost-effectiveness. This study aimed to utilize a natural material, namely rambutan (Nephelium lappaceum L.) leaf extract, as a candidate to be tested for its antibacterial activity against Vibrio sp. A phytochemical analysis of the rambutan leaf extract was conducted to identify the presence of bioactive compounds that inhibit bacterial growth. The extraction was performed through maceration using 70% ethanol as the solvent. The extract was then diluted in a series of concentrations ranging from 100% to 3.125%. Antibacterial activity was tested using the disk diffusion method on Thiosulfate Citrate Bile Salt Sucrose (TCBS) agar medium. The results showed a potent inhibitory effect at the 100% extract concentration, with an inhibition zone diameter of 24.675 ± 0.53 mm. Potent inhibition was also observed at 75% and 50% extract concentrations, with inhibition zones of 19.95 ± 1.56 mm and 19.225 ± 4.63 mm, respectively. Phytochemical analysis of the rambutan leaf extract revealed the presence of several bioactive compounds, including alkaloids, steroids, flavonoids, saponins, and tannins. The study concluded by calculating the extract yield to assess the efficiency of rambutan leaf extraction using ethanol, yielding 7.16 ± 0.14%.

Abstract

Fertilization can be applied through the leaves and roots, which have different characteristics and can complement each other. Foliar fertilizer suitable for use in rubber plant nurseries, other than Bayfolan, is Glow Green. This study aims to determine the growth of a rubber plant nursery using foliar fertilizer and root fertilizer, and to compare the fertilization costs. Research from April to September 2023 at the Bogor-Getas Unit Experimental Field, Salatiga. The experimental design used a randomized block design with 9 treatments and 3 replications. Treatments consisted of a control without fertilization, 50% root fertilizer, 100% root fertilizer, and a combination of root fertilizer at three dose levels (0%, 50%, 100%) with Bayfolan and Glow Green. Glow Green can reduce 50% dose of root fertilizer with plant height growth, stem diameter, and dry weight that are not significantly different compared to 100% root fertilizer and higher than 50% root fertilizer. The dry weight in the 50% root fertilizer + Bayfolan treatment was lower than in the 100% root fertilizer treatment. Treatment with 50% root fertilizer + Glow Green and 100% root fertilizer + Bayfolan showed higher relative agronomic effectiveness compared to 100% root fertilizer as the standard fertilization (RAE 108% and 105%), with fertilization costs of 89.8% and 117.5%. Glow Green is recommended for large-scale use in rubber nurseries, reducing fertilization costs by 10.2% and reducing the root fertilizer dose by 50%. At the same time, Bayfolan is applied without reducing the root fertilizer dose.

Abstract

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%.

Abstract

Mariculture activities play a significant role in contributing to the country's foreign exchange, as many of its products are exported abroad. Mamuju Regency, situated in West Sulawesi Province, is part of the eastern region of Indonesia and boasts vast potential for mariculture due to its abundant natural resources. However, farmers face several challenges, particularly oceanographic factors such as large waves, variations in freshwater input, and nutrient concentrations from land-based activities. These factors can negatively impact aquaculture media and alter oceanographic conditions, potentially threatening cultivation. The goal of this study was to examine the spatial and temporal dynamics of oceanographic conditions and assess the feasibility of waters for mariculture activities. The research was conducted in the waters around Karampuang Island in Mamuju Regency, using a descriptive quantitative approach. This involved determining sampling stations, measuring water quality both in situ and ex situ, analyzing data to assess the suitability of the waters for mariculture, and creating a GIS-based land suitability map. The results show that the water conditions in Karampuang Island are pretty dynamic, with varying water quality parameters observed, indicating diverse suitability for mariculture. For seaweed cultivation, station 3 was categorized as quite suitable, while stations 1 and 2 were considered appropriate. However, for KJA system cultivation, only station 1 consistently supports cultivation. Further studies are needed to monitor the water quality periodically and conduct cultivation trials to optimize farming activities.
