Waste management by society not only reflects individual responsibility but also plays a crucial role in environmental sustainability and community welfare. This research aimed to understand society’s perception and behavior regarding domestic waste and its surrounding waters. Understanding societal behavior is the key to sustainable environmental management. Direct inquiry was conducted to the sample population of 25 respondents who represented various age, education, and cultural groups in the densely populated residential area surrounding the Brantas River in Dinoyo Ward. Field observations were done to take water quality parameters and monitor the residents’ behavior regarding waste management. The results indicated that 76% of respondents know the impact of river pollution, although most did not contribute actively to reducing their domestic waste volume. About 44% of respondents never saw anyone littering the river, which may be due to the regular waste pick-up system. This was supported by water quality parameters that did not demonstrate any sign of pollution, although high turbidity was indicated. Comprehension of the results of this study is hoped to inspire the ideas of solid intervention plans to increase awareness and decrease the negative impact of domestic waste on the Brantas River in Dinoyo Ward. Keywords: society perception and behavior, domestic waste management, aquatic environment, Brantas River

Staphylococcus aureus becomes a normal flora in humans, especially on the skin and in the nose. However, if it becomes excessive or if there are pathogenic variants, it can cause various health problems. The purpose of the study is to develop a molecular-based detection method for Staphylococcus aureus using the norA primer gene. The norA gene in Staphylococcus aureus is known to play a role in pathogenesis with its antibiotic resistance ability. This type of research is analytical observational with a cross-sectional method. The methods in the study include the isolation and identification of Staphylococcus aureus from healthcare facility equipment. Isolation and identification include bacterial isolation using Blood Agar Plate (BAP) media; isolate purification, Gram staining; biochemical tests using Mannitol Salt Agar (MSA) media, glucose tests, Voges Proskauer (VP) tests, catalase tests, and coagulase tests. Furthermore, S. aureus isolates were tested using a molecular-based method, namely Polymerase Chain Reaction (PCR). This method includes DNA isolation stages, qualitative testing with agarose gel electrophoresis, semi-quantitative testing with image J software, amplification with Real-Time Polymerase Chain Reaction (RT-PCR) using norA gene primers. The Mann-Whitney test results gave a value of p = 0.334 (p> 0.05) indicating the suitability between the culture method and the PCR method with the developed protocol in detecting Staphylococcus aureus. The developed method includes the use of base sequences in the norA gene primer, optimization of annealing and extension temperatures, and the concentration of DNA templates used.

Ekstrak tumbuhan mengandung metabolit sekunder berupa flavonoid dan senyawa fenolik yang memiliki aktivitas antibiotik. Uji aktivitas antibiotik dapat dilakukan dengan metode cakram Kirby-Bauer yang aktivitas antibiotiknya ditunjukkan dengan terbentuknya zona bening. Penelitian ini dilakukan dengan menggunakan ekstrak daun Moringa oleifera dan kladode Opuntia cochenillifera yang diekstrak menggunakan etil asetat sebagai pelarut. Uji aktivitas antibiotik terhadap bakteri Staphylococcus aureus dilakukan pada media Mannitol Salt Agar dan Luria Bertani Agar. Cakram Kirby-Bauer yang digunakan adalah Antimicrobial Disc Oxoid® dan Filter Paper. Hasil penelitian ini menunjukkan bahwa penggunaan Antimicrobial disc Oxoid® dan Filter Paper tidak menunjukkan perbedaan secara statistik pada hasil zona bening (t-value = 0,45; p-value = 0,655; dengan α = 95%). Sementara itu, hasil Clear Zone pada Mannitol Salt Agar memberikan hasil yang lebih baik daripada Luria Bertani Agar dan signifikan secara statistik (nilai-t = 2,46; nilai-p = 0,02; dengan α = 95%). Temuan ini menunjukkan bahwa kertas saring dapat menjadi alternatif yang murah untuk uji antibiotik dengan hasil yang tidak berbeda secara signifikan dibandingkan dengan cakram antibiotik komersial. Namun, uji antibiotik terhadap Staphylococcus aureus lebih baik dilakukan pada Mannitol Salt Agar dibandingkan dengan Luria Bertani Agar.

Plant growth-promoting rhizobacteria (PGPR) has been detailed to affect soil microbial exercises or community composition. There is a lack of information on the degree to which PGPR as a biofertilizer concurrently influences the action, estimate, and composition of the soil microbial community. This research investigated the impacts of the timing and frequency of PGPR application as biofertilizers on the rhizosphere bacteria community in arable soil. We compared four treatments in an experimental field site, namely: one-time treatment of PGPR at the beginning of planting (P1), twice treatment of PGPR (P2), 15-days of planting (DP), and 30-DP (P3); and without treatment of PGPR (WP). A total rhizosphere bacteria community fingerprint was surveyed using ribosomal intergenic spacer analysis (RISA) using a culture-dependent and culture-independent approach. The rhizosphere bacteria community was surveyed during 80 DP. The unweighted pair-group method with arithmetic mean (UPGMA) clustering showed that the rhizosphere bacteria community in three-frequency applications of PGPR was more abundant than without PGPR application and one or two PGPR applications. This study revealed that the rhizosphere bacteria community was increased in soil with PGPR application, especially in P3, three dosages of PGPR application. Increasing the rhizosphere bacteria community could strongly influence the clay foam soil nutrient.

Microplastic contamination in water provides an ideal surface for biofilm formation. It facilitates other pollutants, such as heavy metals, to attach to their surface. This interaction leads to biological and environmental problems. We tested this phenomenon by investigating the presence of microplastics in water, biofilms on surfaces, and heavy metal accumulation during September 2024. It further examines the relationship between microplastic and their contamination in fish. Samples were collected from two stations, namely Kondang Buntung Fish Auction Place (TPI) and the Indonesian Navy Post, water from Sendang Biru, using a purposive sampling method. A total of 20 liters of water and 6 Banyar fish (Rastrelliger kanagurta) specimens were analyzed. In contrast, biofilm morphology and heavy metal content were analyzed using Scanning Electron Microscopy with energy-dispersive X-ray. The result found that fibre-shaped microplastics, with fragments and filaments, dominated water samples. Microplastics 1-5 mm in size show that their colors included black, blue, red, and transparent. Five biofilm morphologies on the microplastic surfaces were identified: platelet, thin film, solid film, sporous, and diatoms. Heavy metals (Pb, Hg, Cd, Al, Mg, Fe) were detected with weight percentages ranging from 0.473 to 2.533%. Microplastics are found in the digestive tracts of fish, predominantly microplastic as filaments followed by fragments and fibers. We found that biofilm-coated microplastics accumulate heavy metals, posing a risk of pollutant transfer to aquatic organisms.
