Physical Quality Characteristics of Pure and Impure Trigona Bee Honey
No full textThis study aims to determine the physical quality characteristics of pure and impure honey bee Trigona. The material used in this research is pure honey and impure honey. This study consisted of 2 treatments with five replications where X1 (pure honey) and X2 (unpure honey). Parameters observed included soluble test, heating test, hexagon test, and ant test. Data analysis using t-test. Based on the results of the analysis of variance, it shows that each soluble test is X1 = 1.6 and X2 = 3.8, the heating test is X1 = 4.6 and X2 = 2.4, the hexagon test is X1 = 2 and X2 = 1, 8, the ant test is X1 = 3.2 and X2 = 4.2. The study results can be concluded that the effectiveness of the honey purity test using several simple methods that most meet the requirements are the soluble test method, the heating test method, and the ant test. In contrast, the hexagon test does not give a response at all
Microbial Contamination of Horse Meat from Slaughterhouses in Jeneponto Regency
No full textThis research aimed to examine the microbial contamination at horse meat from traditional slaughterhouses in Jeneponto Regency to determine the quality of safe meat for human consumption. The study was conducted with a non-experimental design and observations using survey methods. Ten slaughterhouses were selected with the purposive sampling method, where meat samples were obtained and then analyzed with the total plate count method. The result showed that all samples from 10 horse slaughterhouses have more than 1x106 CFU/gram, which did not meet the SNI requirements, presumed that the meat from horse slaughterhouses was not categorized as safe for consumption. This result indicated that horse slaughterhouses in this research need sanitation and design improvement, along with good slaughtering practices

Indonesian Higher Education of Innovation In Learning English In The Pandemic And New Normal Period
No full textInnovation of learning activities in universities is a necessity because they are considered as actors of innovation itself. This paper aims to explore higher education innovations in Indonesia during the pandemic and post-pandemic that can be utilized in English learning activities. This research is a literature study by utilizing data obtained from online journals, books, and government regulations as analysis material. Higher education innovations can be seen in the government's new concepts and policies that are relevant to the COVID-19 pandemic. Furthermore, the innovation of learning platforms, including digital learning media, is very appropriate to use in online English learning activities from home. These two major innovations, besides being useful for responding to educational challenges during the pandemic, are also a medium for developing independence in student learning
Risk Analysis of Rice Farming in Polenga Village, Watubangga District, Kolaka Regency
Get PDFThis study aims to determine the amount of production risk, cost risk and income risk of rice farmers in Polenga Village, Watubangga District, Kolaka Regency. The basic method used in this research is quantitative descriptive. Determination of the research sample using simple random sampling method, with a total sample of 48 rice farmers. The results of this study are the risks faced by farmers in Polenga Village, Kecamtan Watubangga, which is the production risk,  costs risk and income risk. Based on the value of variation coefficients (CV) obtained, if CV 0.5 then the production risk , costs and farm income borne by farmers is greater, while the value of CV ≤ 0.5, the farmer will always profit or break even. At the production risk , the coefficient of variation (CV) was obtained at 0.1 ≤ 0.5 indicate that the farm  production risk  that burdened by farmers is low. Cost risk obtained by the value of the Coefficient of Variation (CV) of 0.2 ≤ 0.5 indicates that the farm cost risk  that burdened by farmers is low and the farm income risk is obtained a value of  Variation Coefficient(CV) of 0.1 ≤ 0.5 indicates that burdened by farmers is low too

Organogenesis of Cavendish Banana (Musa acuminata L.) Plant in Various Concentrations of ZPT IAA (Indole Acetic Acid) and BAP (Benzyl Amino Purine) Vitro
Get PDFBananas are a horticultural commodity that originates from Southeast Asia and the West Pacific, including Indonesia. Banana cultivation is carried out with the aim of increasing the economic value of the community by cultivating the Cavendish banana species. Cavendish banana (Musa acuminata L.) is one type of banana that is widely exported, and has high economic value. The constraints in the cultivation of this Cavendis banana plant are the small, high-quality tillers produced in large quantities and in a short time. Propagation of seeds with tissue culture technology is one solution in dealing with the problem of providing these seeds. This study aims to determine the effect of ZPT IAA and BAP concentrations on the growth of cavendish banana shoots in vitro. This research was conducted at the Tissue Culture Laboratory of the Faculty of Agriculture, Cokroaminoto University, Palopo, on Jalan Lamaranginang, Batu Pasi Village, Wara Utara District, Palopo City. Starting from January to May 2020. This research was arranged in a completely randomized design (CRD), which consisted of 5 treatments and 3 replications with a total of 15 experimental units. By giving treatment concentrations of P0: Control, P1 (IAA 0.5 mg L-1 and BAP 1 mg L-1), P2 (IAA 1 mg L-1 and BAP 2 mg L-1), P3 (IAA 1.5 mg L-1 and BAP 3 mg L-1), P4 (IAA 2 mg L-1 and BAP 4 mg L-1). With research parameters callus color, callus texture, root emergence time, shoot emergence time, number of shoots, and number of leaves. The results showed that at the concentration with treatment P3: IAA 1.5 mg L-1 and BAP 3 mg L-1 produced the highest number of leaves, namely 3 strands. The fastest root emergence time was 25.33 days and the highest number of shoots was 2.33. While for the time of emergence of treatment shoots P0: Control showed the best results, namely 7 DAS (days after planting). This is because a balanced amount of auxins and cytokinins can affect the growth of banana plants in vitr

No full textThe seventh grade science teacher at MTsN 3 Kota Pariaman has problems in developing an instrument for assessing higher order thinking skills. In the 2013 curriculum, teachers are required to be able to provide questions in the C4-C6 domain, namely High Order Thinking Skills (HOTS). This study aim to produce a valid and practical assessment instrument for higher order thinking skills on environmental pollution material at the C4-C6 cognitive level. The background of this research is that the questions made by the teacher are still at the C1-C3 level and there are still obstacles for teachers in developing higher order thinking skills assessment instruments, while inthe 2013 curriculum teachers are required to be able to provide questions in the C4-C6 domain. This type of research is research development (Research and Development) which is a research method used to produce certain products. This type of research uses 3 stages of the 4-D model, namely the define, design and develop stages.Based on the research conducted, a very valid assessment instrument of 3,32 was produced by thevalidator, the empirical validity there were 30 valid questions and 10 invalid questions, the reliability in this study was 0,77 with the category of reliability, 94,79% teacher practicality and practicality. students amounted to 80,80%, the difficulty level of the questions was between 0,31 to 0,70 with moderate criteria and the question difference had sufficient criteria. This research can be used as a reference for other researchers related to the development of higher order thinking skills assessment instruments.Keywords : High Order Thinking Skills, Validit
