Abstract

Chili is one of the plants that are needed by the community so that proper cultivation techniques are needed, in this case related to fertilization by utilizing organic animal waste.This study aims to determine the response of the growth and production of red chili (Capsicum annum L.) to chicken and cow manure dose combination. The method used is an experimental method with a factorial completely randomized design which consists of two factors, namely the first factor is the type of animal manure which consists of two levels, namely cow dung and chicken manure, the second factor is the dose of fertilizer there are three levels, namely 200 grams, 300 grams and 400 grams. The total combination of treatments was 9 treatments and 3 replications so that in total there were 27 units. The parameters observed were chili growth (height and number of branches) and chili production (number of fruits and fruit weight). The data were analyzed of variance with 5% and 1% levels, followed by Duncan's 5% further test. The results of the analysis showed that the combination of treatments had a very significant effect on plant height and fruit number (12.77 and 5.00), significantly affected the number of fruits (3.55), but did not affect the wet weight of fruit (2.46).Further test results showed that the best treatment for the parameters of plant height, number of branches, and number of fruit was a combination of 300 grams of chicken manure and 200 grams of cow manure. Keywords: dose, chicken manure, cow manure, growth, production

Abstract

The RQA (reading, questioning, and answering) learning model is an active learning model that emphasizes reading, asking, and answering. This study aims to determine the application of reading, questioning, and answering (RQA) learning strategies in improving student learning outcomes in class XI SMA N 6 Kerinci. This research is a type of quantitative research with experimental methods. The research population came from class XI SMA N 6 Kerinci, amounting to 44 people. The sample came from class XI MIPA 2, which amounted to 22 people. The sampling technique in this research is the random sampling technique. Data collection techniques in the form of observation and tests. The test is used to see student learning outcomes using reading, questioning, and answering (RQA) learning strategies. The research instrument is a test in the form of objective questions totalling 30 items carried out for validity, reliability, difficulty index and discriminatory power. Data analysis technique using T-test and N-Gain. The results showed that 1) the results of the study before applying the RQA strategy the highest score of students was 70 and the lowest score was 40 with an average pretest score of 51.59, 2) student learning outcomes after implementing the RQA learning strategy obtained the highest score of 90 and the lowest score of 65 with the result the average posttest is 78.18, 3) there is a significant difference in the application of the RQA strategy in improving student learning outcomes in class XI SMA N 6 Kerinci. Keywords:   Strategy of RQA, Learning Outcomes,

Abstract

Gastropods have an important role in the aquatic food chain. The purpose of this study was to determine the abundance of Gastropod species in the area around the estuary of Liku Village, Samaturu District, Kolaka Regency. This research was conducted in Liku Village, Samaturu District, Kolaka Regency. The research variable consists of the independent variable (X) in the form of the calculation of gastropod abundance and the dependent variable (Y), namely the estuary area of Liku Village, Samaturu District, Kolaka Regency. The method used in this practicum is the plot placement method with the design of using observation stations for 3 repetitions in which 5 plots of observation sampling are made in each station, so that in total there are 15 data collection times. The data analysis technique used is descriptive technique. The abundance calculation results showed that the abundance of 2 species Telescopium telescope and the Littorina scabra species. Keywords: Estuary, abundance, Gastropods.

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
