Baluran National Park is a Natural Resources Conservation area. Avifauna is a perfect indicator to determine environmental health and the value of biodiversity as a whole. This study aimed to assess the diversity of avifauna species and their abundance in Baluran National Park. This research using a combination line transect and point count method. The results showed that Baluran National Park has high species diversity. Species found during the study were 36 of 24 families. As many as 11% (4 species) of birds are in a large category, 39% (14 species) in a general category, 19% (7 species) in a frequent category, 6% (2 species) in an uncommon category and 25% (9 species) in a rare category. Based on the research results, it can be concluded that there are various kinds of avifauna in Baluran National Park.Keywords: Avifauna, Baluran National Park, Diversity, Line Transect, Point Count.

Rhizophora mucronata Lamk. is widely used for rehabilitation of mangrove areas because the fruit is easily obtained, sowing and can grow in areas of high or low tidal inundation. This study aims to know the effect of high-low waterlogging on fecundity (the development of fruit into mature propagules) Rhizophora mucronata Lamk and to determine the characteristics of the ecosystem environment on the Rhizophora mucronata Lamk fecundity. The study was conducted in the Marobo River Mawasangka, Buton Tengah, Southeast Sulawesi. Observations were made in the downstream area towards the headwaters of the river. Each zone is made 100m baseline; the distance between sub-transects is 25m. Each subplot was plotted by making 2x2m2 quadrant plots for Rhizophora mucronata Lamk. earning productive interest, propagules and seedlings, making it easier to count the number of seedlings. Fecundity (counting the number of fruits until the propagules ripen each tree) and measurement of environmental chemical physics. Fecundity comparison analysis between the two zones by using a t-test. The results of the study based on the t-test, there is a significant difference in the percentage of fruit and propagules in zones 1 and 2 with a value of p 0.05, the highest average fruit is in zone 1 (79.9%). The highest propagule average is in zone 2 (33, 9%), highly influential in the high-low of puddles with salinity levels of zone 1 (20%) and zone 2 (10%). The results showed that there was a high-low waterlogging effect on the Rhizopora mucronata Lamk fecundity

Soursop leaf extract (Annona muricata L.) contains a many potential active compounds, one of which is antifungal. Bolu Paranggi is a traditional cake from Mandar (West Sulawesi), made from wheat flour and brown sugar so it is at risk of being damaged and overgrown with fungus. This study aimed to extract soursop leaves using double RO (Reverse Osmosis) water solvent with variations in extraction time and the ratio of soursop leaf mass and water volume, identify groups of secondary metabolites compounds from soursop leaf water extract, isolate and identify fungi in Paranggi Bolu cake, and perform antifungal activity test of soursop leaf extract against fungi isolated from Paranggi Bolu cake. Extraction of soursop leaves using double RO water as a solvent with maceration for 24 hours and heating for 15 minutes with a variation of the ratio of soursop leaf mass and water volume of 1:1; 1:1.5; 1:2; 1:2.5; and 1:3. The analysis of the secondary metabolite compound was analyzed using the phytochemical test method and antifungal activity using the agar diffusion method on PDA (Potato Dextrose Agar) media and then measuring the inhibition zone using 6 mm diameter paper discs. The results showed that extraction with the heating method for 15 minutes produced more extract than the 24-hour maceration method at room temperature (RT), where the highest amount of extract was obtained from the ratio of soursop leaf mass and water volume of 1:3. The results of the phytochemical analysis of soursop leaf water extract, both heating and maceration methods, contained flavonoids, alkaloids, terpenoids, steroids and saponins, and antifungal activity tests against Aspergillus isolated from Bolu Paranggi showed weak antifungal activity at extract concentrations of 5,000 ppm - 50,000 ppm. with an inhibition zone diameter of 2 mm.

Changes on the mangrove ecosystem, directly and indirectly, affect the living organisms associated with it, including Molluscs. This study aimed to investigating Molluscs species in mangrove ecosystem of Kendari Bay. It is descriptive research containing facts and natures of mangrove Mollusc species. This study conducted from September to November 2020. Observing and collecting the Mollusc organisms were carried out in four mangrove ecosystems like Bruguiera, Bruguiera/Rhizophora, Rhizophora, and Avicenia. The method used in this research was an exploring technique by collecting and counting the found Mollusks. Indicators of observing the Mollusks included morphological characteristics and environmental parameters. Three important environmental parameters, like salinity, acidity (pH), and temperature, were measured during field works using hand refractometer, pH tester, and thermometer, respectively. This research indicates about 279 individuals of Mollusks found in all zones consisting of 17 species representing two classes, Gastropod (14 species) and Bivalves (3 species). During this research, the Gastropod Mollusks found Telescopium-telescopium, Terebralia palustris, T. sulcata, Cerithideopsilia cingulata, C. alata, Nerita squamulata, Cerithidea quadrata, C. obtusa, Latirus paetelianus, Cerithium kobelti, Chicoreus capucinus, Nassarius stolatus, N. niticusis, Siphonalia varicosus. For the three species of Bivalves are Polymesoda erosa, Anadora granosa, and Sacostrea cucullata. The both species T. sulcata and S. cucullata positively dominated all total found Gastropods and Bivalves namely 21.86% and 3.943%, respectively. The three water quality parameters measured at research stations are still on tolerance limits for the collected molluscs. Keywords: Molluscs, Mangrove Ecosystem, Kendari Bay

The massive Covid-19 pandemic has caused countries to implement policies in the form of social restrictions to limit activities outside and only carry out activities indoors. The risk of contracting the Covid-19 virus causes a reduction in public activities in the form of commercial, institutional, and public service facilities. This has an impact on the amount of waste generated by people in urban areas during the pandemic. Therefore, this study aims to determine the effect of covid-19 on the amount of waste that enters the Toisapu TPS in Ambon city and to see the difference in the average amount of waste before the pandemic and during the COVID-19 pandemic with Paired Sample T Test analysis using IBM SPSS statistics 25 application. The results showed that there was a correlation between the two variables (0.693) which means that the correlation of the amount of waste entering the Toisapu TPS between before and during covid-19 was strong but not significant as indicated by the probability value (sig.) 0.013 0.05. While the calculated t value is 3.16 2.63 (t table value) so it can be concluded that the average amount of waste before and during the Covid-19 period is different.

Cocoa (Theobroma cacao L.) is one of the people's plantation crops with promising prospects because it can flower and bear fruit throughout the year. One of the efforts to improve the quality of cocoa seeds is by increasing the viability and vigor of seeds through seed invigoration techniques. This study aimed to determine the effect of biopriming invigoration treatment techniques in increasing cocoa seeds' viability, vigor, and growth. This research was conducted at the Laboratory of Agronomy Unit of the Faculty of Agriculture of Halu Oleo Kendari from April to May 2019. This study used a completely randomized design (CRD) consisting of 4 treatments: Control (B0), Bio-priming Bacillus sp. CKD061 (B1), Bio-priming Pseudomonas flourescent (B2), a combination of Bio-priming Bacillus sp. CKD061 with Pseudomonas fluorescent. Each treatment was repeated three times, so there were 12 experimental units. The data obtained were analyzed using variance analysis and continued using the Least Significant Difference Test (LSD). Based on the results of research that biopriming treatment using rhizobacteria has the best influence on the viability, vigor and growth of cocoa seeds.
