Abstract

Teluk Nare, situated in North Lombok Regency, is a coastal region abundant in marine resources, serving as a hub for fisheries and marine tourism. This research seeks to evaluate the abundance and diversity of plankton as a measure of the ecological health of Teluk Nare’s aquatic environment. Sampling was conducted in February 2025 across ten stations using the purposive sampling technique. Water samples were collected with a plankton net, preserved using Lugol’s solution, and analyzed at the University of Mataram’s Hydrobiology Laboratory. The findings revealed 18 plankton genera from seven classes, with Coscinodiscus, Copepoda, and Nauplius being the most prevalent across all stations. Plankton abundance ranged from 12,000 to 32,333 cells per liter, with the highest concentrations observed near river estuaries. The diversity index indicated moderate levels (1.67–2.08), the evenness index was high (0.71–0.89), and the dominance index was low (0.16–0.26), suggesting no single dominant species and a relatively stable ecosystem. Factors such as currents, salinity, and water transparency were found to influence plankton distribution and abundance. These results offer valuable insights for the sustainable management of Teluk Nare’s coastal ecosystem.

Abstract

Fertilization is one of the most important maintenance activities for the growth of pre-nursery oil palm seedlings. This study aims to determine the effect of SP-36 fertilizer and aloe vera POC on the growth of oil palm seedlings. This study used a non-factorial Randomized Group Design (RAK) with 5 treatments and 5 replicates so that 25 experimental units were obtained, with the treatment sequence namely P0 = Without SP-36 Fertilizer and Aloe Vera POC, P1 = SP-36 fertilizer 5 g/plant + POC Aloe Vera 50 ml/plant, P2 = SP-36 fertilizer 10 g/plant + POC Aloe Vera 100 ml/plant, P3 = SP-36 fertilizer 15 g/plant + POC Aloe Vera 150 ml/plant, P4 = SP-36 fertilizer 20 g/plant + POC Aloe Vera 200 ml/plant. Parameters observed were the number of leaf midribs, plant height and stem diameter. The results of the analysis of variance showed that the provision of SP-36 fertilizer and POC aloe vera did not have a significant effect on the number of leaf midribs, plant height and stem diameter of pre-nursery oil palm seedlings. The best treatment was obtained in the P2 treatment (10 g SP-36 + 100 ml POC aloe vera).

Abstract

Diabetes mellitus is an escalating public health concern worldwide, with Indonesia being one of the countries heavily affected and facing a projected increase in cases. This condition is known to cause a range of complications, including hearing loss, which is frequently observed in diabetic individuals. This study aims to investigate the potential protective effect of honey against cochlear damage induced by diabetes mellitus. This ex-vivo experimental study applied a pretest-posttest control group design. Conducted over five months at the FMIPA USU Animal Laboratory, the study involved 25 healthy adult male Rattus norvegicus Wistar rats (150–250 grams, aged 2–3 months). The rats were divided into three treatment groups and assessed before and after honey administration on days 0, 3, 6, 9, and 12. SNR value differences were analyzed using Repeated Measures ANOVA or the Friedman test. Administration of honey at a dose of 1 g/kg body weight was more effective in preventing the decline of SNR values in diabetic rat models compared to the 2 g/kg dose. Honey demonstrates a protective effect against cochlear hair cell damage in diabetic Rattus norvegicus, as evidenced by SNR values from OAE assessments.

Abstract

Pseudomonas aeruginosa and Staphylococcus aureus are common causative bacteria in Chronic Suppurative Otitis Media (CSOM). Honey, as a natural substance, has shown antibacterial activity. To evaluate the antibacterial effect of honey at different concentrations on P. aeruginosa (clinical isolates and ATCC 27852) and S. aureus (ATCC 29213) compared to ofloxacin. An experimental in vitro study using post-test only design was conducted. Bacterial isolates from CSOM patients and ATCC strains were exposed to honey at concentrations of 60%, 70%, 80%, 90%, and 100%. Zone of inhibition was measured using the agar diffusion method. Honey exhibited significant antibacterial activity against all tested bacteria. The highest inhibition zones were observed at 100% concentration. Ofloxacin showed greater inhibition than honey in general, but honey still demonstrated moderate to strong activity. Honey has potential as a natural antibacterial agent against P. aeruginosa and S. aureus, and may serve as an alternative or adjunct treatment for CSOM.

Abstract

The utilization of organic waste as a cultivation medium is a crucial step towards promoting sustainable agriculture and mitigating environmental impact. This study aims to evaluate the effect of adding mushroom baglog waste on the population growth of earthworms (Lumbricus rubellus), serving as supporting material in invertebrate zoology. This quantitative research, employing a true experimental method (True Experimental Research), was conducted for 60 days in the researcher's yard at Kebon Kopi Complex, Pejeruk Village, Ampenan District, Mataram City. The research design utilized a completely randomized design with five treatments and seven replications. The applied treatments included P0 (0% mushroom baglog waste), P1 (25% waste), P2 (50% waste), P3 (75% waste), and P4 (100% mushroom baglog waste). The observed parameters were the number and weight of earthworms. Research data were analyzed using the ANOVA test and the Least Significant Difference (LSD) test. The analysis results indicated that the addition of mushroom baglog waste significantly affected the earthworm population (P<0.05), suggesting that different proportions of mushroom baglog waste can increase both the number and weight of earthworms.

Abstract

The role of allergy in chronic rhinosinusitis is still controversial. Numerous studies have demonstrated that atopy is highly prevalent in people with chronic rhinosinusitis (CRS), and that allergies may play a part in the pathogenesis of the condition. Allergy disorders, particularly those involving IgE-mediated in/flammation, are generally considered as triggering factors in the development of chronic rhinosinusitis or comorbidities/associated factors for the spread of chronic rhinosinusitis. The study aimed to determine the relationship between allergies and chronic rhinosinusitis. Observational analytical study with cross-sectional approach. 30 patients with symptoms of runny/blocked nose were examined. Allergy test, namely skin prick test, has been examined to categorize allergic and non-allergic patients. Total serum IgE and total eosinophil examination from blood were then categorized as increased and normal. The criteria for chronic rhinosinusitis are complaints of runny/blocked nose and facial pain and/or decreased sense of smell. Thirty patients (19 females and 11 males) aged 17 to 77 years were examined in this study. 19 patients were confirmed to have rhinosinusitis and 11 had rhinitis. The results of the analysis using the Chi Square test showed that there was no significant relationship between allergy, IgE, eosinophils, and chronic rhinosinusitis (p>0.05). There was no significant relationship between allergy, IgE, eosinophils with chronic rhinosinusitis.

Abstract

Inulin is a polysaccharide, consisting of fructose units. Inulin has several benefits for our own bodies and for industrial circles. Inulinase E.C.3.2.1.7. is a hydrolytic enzyme that catalyzes the hydrolysis reaction of inulin polysaccharides into fructose and/or fructooligosaccharides. This study aims to determine the growth rate of Fusan FP4 inulinnase and the production of Fusan FP4 inulinnase at yeast extract concentrations of 0.15% and 0.2%. Conversion of tubers into fructose with enzymatic techniques (inulinase enzyme) can produce 95% fructose. Fusan FP4 is a protoplast fusion of indigenous yeast Pichia manshurica. Yeast Extract is a source of Nitrogen for microorganisms in culture media. The concentration of Yeast Extract in the media can affect the growth and metabolic products of microorganisms. Inulinase activity was determined by measuring reducing sugars combined with inulin as a substrate. This activity was measured using a spectrophotometer at a wavelength of 520 nm. The study showed that the specific growth rate at a yeast extract concentration of 0.2% was higher than yeast extract concentration of 0.15%. However, The highest inulinase activity was found at a yeast extract concentration of 0.2%.

Abstract

Fruit flies (Bactrocera sp.) are important pests of horticultural crops because they can cause serious damage and reduce the selling value of the fruit. This study aims to determine the effect of lemongrass (Cymbopogon nardus) plant extract on the number of fruit fly catches and to determine the most effective concentration as a natural attractant. The study was conducted experimentally in a crystal guava plantation in Dasan Tapen Village, West Lombok, using a Randomized Block Design (RBD) with five treatments of lemongrass extract concentrations (0% - 60%) and three replications. Data were analyzed using one-way ANOVA and continued with the LSD test. The results showed that there were four species of fruit flies caught, namely Bactrocera dorsalis, B. carambolae, B. cucurbitae, and B. papayae, with a total of 671 individuals. The 60% concentration produced the highest number of catches (an average of 69), while the control without attractant did not produce any catches. Statistical analysis showed a significant effect between treatments (p < 0.05). It can be concluded that lemongrass ethanol extract has a significant effect on the number of fruit fly catches, and the highest concentration in this study (60%) is more effective than the concentration below it. The concentration of 60% has the highest capture compared to the concentration below it. The use of lemongrass as a natural attractant has the potential as an alternative to environmentally friendly pest control in an integrated agricultural system.
