Cellulase enzyme activity is essential for the breakdown of cellulose, a major component of plant cell walls. This enzyme is produced by a variety of microorganisms, including fungi such as mushrooms. This study aimed to evaluate the cellulase enzyme activity extracted from the baglogs of three different mushrooms: Pleurotus cystidiosus (brown oyster mushroom), Pleurotus ostreatus (white oyster mushroom), and Auricularia auricula (wood ear mushroom). The extraction was conducted using three different solvents: aquadest (distilled water), saline solution, and citrate buffer at pH 4. The cellulase activity was assessed under optimal conditions of 60 °C incubation temperature and 60 minutes incubation time. The results indicated that the lowest cellulase activity was found in the baglogs of Pleurotus cystidiosus extracted with aquadest, measuring at 0.0253 IU/mL. Conversely, the highest cellulase activity was observed in the baglogs of Pleurotus ostreatus extracted with aquadest, with an activity level of 0.0728 IU/mL. The glucose concentration, which serves as an indicator of the enzymatic hydrolysis of carboxymethyl cellulose (CMC), was highest in Pleurotus ostreatus extracted with aquadest at 393.043 ppm. These findings suggest that Pleurotus ostreatus is the most effective species for cellulase production among the tested mushrooms when extracted with aquadest. The optimal extraction and assay conditions determined in this study can guide future research and industrial applications in enhancing cellulase enzyme production from mushroom baglogs, particularly in bioconversion processes and bioethanol production.

Endophytic bacteria and fungi inhibite the tisues of living plant. Both of them are significant components of plant microecosystems. Current research was performed to explain several microbiological activities (production of extracellular enzymes, antioxidants, and antibacterials) of endophytic bacteria and fungi from binahong leaves extract (Anredera cordifolia (Ten.) Steenis). In this case, the research was conducted by applying a review of several literature reviews published online on Google Scholar and several journals listed on the ScienceDirect site. Based on the results obtained from the research reports from several scientific journal sources, there are four types of extracellular enzymes produced by the endophytic bacteria of the Anredera cordifolia plant, including proteinase, amylase, esterase, and cellulase. In addition, the endophytic bacteria of Pseudomonas aeruginosa from the leaves extract of Anredera cordifolia has antioxidant activity, which is volatile compounds including cis-9-Octadecenoic acid, 2-dodecenoic acid, and 9 octadecenamide produced by endophytic bacteria of Pseudomonas sp. Furthermore, the endophytic bacteria isolated from Anredera cordifolia leaves extract inhibits the growth of E. coli ATCC 35216 and S. aureus ATCC 29523. Meanwhile, the endophytic fungi from Anredera cordifolia leaves extract inhibite the growth of E.coli and S. aureus bacteria. Therefore, understanding the relationship between bacteria and endophytic fungi from the leaves extract of binahong (Anredera cordifolia (Ten.) Steenis) is essential. This knowledge can be utilized and applied well for the future production of higher quality and more medicinal plants from binahong plant (Anredera cordifolia (Ten.) Steenis).

Bronchopneumonia is an infiltrate spreads to both lung hemispheres starting from the terminal bronchioles which further become blocked by exudate. This is often experienced by infants and children due to bacteria, viruses, fungi, and foreign things. The annual bronchopneumonia cases in Indonesian infants is estimated in the range of 10% -20%, with the Mortality Rate is 32 deaths per 1,000 live births before the age of 5 years old. The current case study report explains an overview of bronchopneumonia and the overcome of the nursing problem of ineffective airway clearance in three pediatric patients at RSU UKI Jakarta. In this case, the nursing process approach includes interviews, observations, implementation, and documentation of results. After that, the nursing actions were implemented for 3x24 hours, in this case is teaching deep breathing exercises, effective coughing, and chest physiotherapy for every 2 hours, fulfillment of oral warm fluids to help thin phlegm, as well as psychological comfort. In this case, the patient's parents can actually perform chest physiotherapy independently to increase coughing ability so that the sputum production decreases and respiratory function restores. Therefore, it will lead to the fulfillment of oxygen needed, thus the problem of ineffective airway clearance is overcome. Eventually, it is suggested that the family becomes a constant in the child's life as well as helping the child's healing. Therefore, the involvement of the family during the family-centered treatment process is important. In addition, as nursing care providers for patients and families, nurses need to improve their quality in paying attention to the biopsycho-socio-spiritual, cultural aspects, and have a caring character as a role model to carry out promotive, preventive, curative, and rehabilitative health care.

Cocoa (Theobroma cacao L.) cultivation by local communities in Papua Indonesia is still done traditionally using shade plants which generally grow naturally. The purpose of this study was to identify trees that grow naturally in three cocoa plantation areas of the local tribe, Sidey District Manokwari, West Papua. This research is an exploratory study using vegetation analysis techniques. Vegetation data collection was carried out using a 20 m × 20 m nested square plot method. The results showed that there were variations in the composition of vegetation and environmental parameters in the three research locations. Overall 70% is dominated by seedlings and saplings while only 30% of mature trees. The Womnowi Village (KW) location was dominated by Dracontomelon dao, Homalium foetidum and Octomeles sumatrana trees, while at the Kaironi Village (KK) and Sidey Makmur Village (SM) locations it was dominated by Durio zibethinus, Piper aduncum and Naphelium lappaceum. The index of diversity and evenness in the seedlings and saplings group was categorized as moderate, while in the mature tree group it was classified as low. Cocoa shade trees in the KW location have species similar to natural forests and need further investigation in terms of ecological and conservation functions.
