Analisis Kualitas Ruang Terbuka Hijau Kebun Raya Kendari
Rapid urban development to meet the population\u27s needs impacts ecological changes and a decrease in environmental quality. Green Open Space (RTH) is an important element in supporting ecological balance and improving the quality of the urban environment. Although Law No. 26 of 2007 mandates the allocation of 30% of land for green spaces, in reality only about 10% is managed privately and 20% by the public sector. This study aims to evaluate the quality of the 113-hectare Kendari Botanical Garden, Southeast Sulawesi\u27s first conservation space, which is experiencing accessibility and infrastructure challenges despite physical development. The methods used include interviews, observations, and literature studies, with descriptive analysis of accessibility, activities, and facilities aspects. The results showed that the accessibility aspect received a good rating, while the activity and facility aspects were in the fair to good category. This research emphasizes the need for improvement to meet the needs of sustainable urban planning and increase visitor comfort so that Kendari Botanical Garden can function optimally as an inclusive and user-friendly green space
Produksi Biofilm oleh Strain Klebsiella pneumoniae Resistan Antibiotik
Klebsiella pneumoniae is known as a Gram-negative bacterium that most often causes infections and is resistant to antibiotics, making it very difficult to treat. Bacteria have several resistance mechanisms, one of which is biofilm production. The purpose of this study was to analyze the biofilm production of Klebsiella pneumoniae strains that are resistant to the antibiotic ciprofloxacin, as a form of defense mechanism. The in vitro research method was used to achieve the goal, carried out by testing clinical specimens of blood, sputum, pus, urine, feces, pleural fluid, with the process of isolation and identification, resistance testing and measuring biofilm production. The tested resistant K. pneumoniae isolates have a resistance mechanism by producing strong, medium and weak qualification biofilms, as well as low porin cell permeability. A strong significant correlation was formed in biofilm production with the amount of bacterial cell growth at the MIC value, which can increase cases of resistance prevalence.

Pemanfaatan Ekstrak Tanaman Gedi (Abelmoschus manihot L.) Asal Kabupaten Wakatobi Sebagai Bahan Aktif Antibakteri Dalam Pembuatan Hand Sanitizer: Pemanfaatan Ekstrak Tanaman Gedi (Abelmoschus manihot L.) Asal Kabupaten Wakatobi Sebagai Bahan Aktif Antibakteri Dalam Pembuatan Hand Sanitizer
The most important health problem in developing countries, including Indonesia, is infection, which is transmitted by microorganisms. Various types of microorganisms attach to hands every day through physical contact with the environment. Hand sanitizer can be the product of choice for today\u27s society. Hand sanitizers can be made from alcohol, glycerol, trichosan and other chemicals. The alcohol content in the hand sanitizer has bactericidal activity, but excessive use of alcohol can cause irritation to the skin, especially in children. Utilization of extracts from traditional herbal gardens can be an alternative to overcome this. Gedi (Abelmoschus manihot L.) is a plant that is often used as traditional medicine by people in Wakatobi Regency and is known to contain antimicrobial compounds in the form of flavonoids, alkaloids, steroids, and saponins which have been shown to have antibacterial effects. This study uses gedi plant extract as a sample of the active antibacterial ingredient in the manufacture of Hand Sanitizer which will be tested using bacteria Staphylococcus aureus in the UHO FMIPA biomolecule and environmental laboratory to see its antibacterial ability. The results of the organoleptic test showed that the Hand Sanitizer was in the form of a liquid preparation, had a distinctive smell of gedi plants, was green in color and felt cold when used. The results of the inhibition zone test at gedi leaf extract concentrations of 45, 35 and 25%/100 ml hand sanitizer showed that preparations containing 45% extract had the greatest inhibition with an average of 17.97 mm. The weakness of this product is generally found in the specific aroma of gedi leaves which gets more pungent with an increase in the concentration of the extract. So that it is necessary to add other aromas to be able to compete with commercial products made from active alcohol which also use perfume
