Abstract

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

Abstract

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.                 Keywords: Pandemic, waste, T test

Abstract

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. Keywords: Biopriming, cocoa seeds, rhizobacteria, seed growth

Abstract

This research aims to determine the effect of giving POC to tofu waste production of cayenne pepper plants, as well as knowing the effective POC dose for cayenne pepper plants. This research was carried out from November 2022 to January 2023 and took place in Sea Village, Kolaka Regency. This type of research includes experimental research consisting of 5 treatments and 4 replications to obtain 20 polybags with a total of 20 research plants. The parameters observed were the number of fruits (fruit) and fruit weight (grams). The research results show that from the parametric test using analysis of variance (ANOVA), the parameter data value for the number of fruit is 0.082 and the weight of the fruit is 0.225; the significance value is more than 0.05, thus H0 is accepted and H1 is rejected. So it can be concluded that there is no significant effect of giving tofu waste POC on the production of cayenne pepper plants. Keywords: Cayenne Pepper Plants ( Capsicum frutescens L.), Tofu Waste POC, and Production

Abstract

Benthic animals are often used as biological indicators of water quality because benthos have relatively fixed habitats, with such characteristics, changes in water quality and the substrate where they live greatly affect their composition. Benthic density is also strongly influenced by its tolerance and sensitivity to environmental changes. The purpose of this research is to determine the type of macrozoobenthos in the Lalolara River, Kambu District, Kendari City. This type of research is descriptive research with observational sampling techniques. The observation technique used is to go directly to the deep field observation and sampling of the flow of the Lalolara River. The river is about 20 m wide meter is divided into 20 observation points. Sampling was carried out on each line transect where each transect consisted of 4 plots measuring 30 x 30 cm. The results showed that there were six types of benthos found in the river Lalolara namely: Tarebia granifer, Pleurocera acuta, Medulia carinata, Planobula armigera, Viviparus interitextus, Parapholyx effusa. Based on the results of the study, it appears that the species Tarebia granifer dominates both forms of the substrate. Also from the observations, the comparison between substrates shows that the sandy substrate has a large number of individuals with a higher diversity than the silty substrate Keywords: Diversity, Bentos

Abstract

The village of Lamundre is an area overgrown with a mangrove ecosystem of 4 hectares and is well developed on the coast. The area can be well overgrown with mangroves because of environmental conditions and other supporting factors such as muddy substrate, muddy sand in tidal transition areas, salty, brackish water and the presence of currents/waves that are classified as mangrove growing conditions. This study aims to determine the types of mangrove plants and environmental parameters on the abundance of mangrove species on the coast of the Rainbow Bridge, Lamundre Village, Watubangga District, and Kolaka Regency. This type of research is descriptive and qualitative by using mangrove samples on the roots, stems, leaves, flowers and fruit. The method used is Line Transect, which uses plots that are aligned on the main line (Basseline) that has been determined in the research area along 280m, the total number of plots is 10, with each plot of 10m x 10m.  Based on the study's results on the identification of mangroves in the Pantai Pelangi Beach, Lamundre Village, Watubangga District, and Kolaka Regency, it shows that mangroves belong to 2 families and                 7 species. The mangroves are from the Rhizophoraceae family namely Rhizophora mucronata species, Rhizophora apiculata, Rhizophora stylosa, Ceriops decandra, Bruguira cyndrica, Bruguira ghymnorryza and the Soneratiaceae family namely Soneratia caseolaris. Keywords: Lamundre village, identification, mangrovee
