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

The current state of the Covid-19 pandemic has had an impact on various ongoing activities, including learning activities. Currently, the government provides a policy to organize learning from home, known as Learning From Home (BDR). Learning From Home in its implementation requires the support of mobile devices. It is a challenge for both teachers and students to master technology in learning in these conditions. In addition, teachers must also be able to carry out the teaching and learning process or provide assessments/evaluations to students face-to-face (done online). The research objective is to determine the use of alternative assessment-based portfolios in biology learning. The authors want to introduce web-based portfolios as alternative assessments in biology learning in this study. Alternative assessments can support students to understand biology lessons with the task of making lab reports, making herbariums, drawing, writing widespread scientific reports, etc. These are collected in the form of website links. The research method used is a literature study that the author has carried out. The results obtained are using a web-based portfolio as an alternative assessment in biology learning, which is still not widely applied even though this assessment is very efficient to apply in biology learning during the Covid-19 pandemic. This research concludes that every lesson that has been carried out certainly needs to be assessed on student learning outcomes in following each lesson that has been followed. In this case, an alternative web-based portfolio assessment is one of the solutions to evaluate the performance and work of students so that all activities carried out can be rewarded with value.                 Keywords: Biology Alternative Assessment, Web Based Portofolio

Abstract

Growth is the process of increasing the number of cell protoplasm in an organism accompanied by an increase in size, weight and number of cells that cannot return to their previous state. One of the factors that influence the growth of koi carp is feed. Good feed is feed that can meet the nutritional needs of the koi carp. The addition of tapioca flour in the feed formula, which contains artificial feed, tapioca flour, and water in the koi carp feed, is one of the proper steps because of the increase in carbohydrate doses that can support the growth of the koi carp. This study aims to determine the benefits of adding tapioca flour to the artificial feed of the koi carp (Cyprinus rubrofuscus) and to determine the effect and the most appropriate dose of adding tapioca flour to the artificial diet of the koi carp (Cyprinus rubrofuscus). The research method used is a quantitative research method accompanied by direct observation and analysis of research data, which is also accompanied by a literature study method from previous studies to support the findings in the research results. The results showed that  the more feed formula was given, the faster the growth of the koi carp produced. But must be accompanied by the right dose, which is 8 grams of feed formula once a day. While the benefits of adding tapioca flour in carp feed are increasing carp production, prolonging goldfish life expectancy, increasing efficiency and nutritional content in carp feed, increasing carp appetite accompanied by increased growth. Keywords: Goldfish Koi, Growth, Feed, Carbohydrates, Tapioca Starch

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
