No full textThe purpose of this study was to see the effect of giving Enterococcus sp. bacteria at Escherichia coli of excreta broiler. The research design used was a completely randomized design consisting of four treatments, three replications, and each replication had four broilers. The treatment given consisted of T1 (0 mL/L), T2 (1 mL/L), T3 (3 mL/L), and T4 (5 mL/L) control treatments. The number of colonies of Enterococcus sp. given through drinking water every day, namely 107 CFU / mL. The results of the study respectively showed the number of Escherichia coli in the treatment of T1 (Log 7.54 CFU/g), T2 (Log 7.53 CFU/g), T3 (Log 7.48 CFU/g), and T4 (Log 6.78 CFU/g). The colony total of Escherichia coli of broiler excreta decreases with increasing doses of Enterococcus sp. It is shown that Enterococcus sp. has an antimicrobial compound activity which can inhibit pathogen growth in broiler digestive tract so that it has the potential to be developed as a probioti
Mechanism of Toxicity and Tolerance in Plants Against Aluminum Stress
No full textAluminum (Al 3+) is rhizotoxic ions in the soil (mineral) acid. Al activities increases with increasing soil acidity, below pH 5.5 the solubility of Al 3+ cations will increase. High level of soluble can cause interference with metabolic processes and plant physiology. Cumulatively, the physiology of metabolic disorders and initially looked at the root system. The tip of the root and lateral roots become thickened and hair and roots become lower, causing a decrease in root length and root tissue enlargement thus inhibiting the growth of roots, the absorption of nutrients and water, will further lower the growth, production and productivity of crops. Although Al disrupt metabolism and suppress the growth of the plant, until a certain threshold of adverse effects in Al still be tolerated, depending on the type of plant and the level of activity of Al. Tolerance of crops to Al can be expressed through two mechanisms, namely: external tolerance mechanism and internal tolerance mechanism. The main difference between the two mechanisms is in the area of detoxification Al whether in symplast (internal) or apoplast (exclusion). The ability of plants to be able to adapt to drought stress Al, depends on the ability of plants to produce organic acid in an amount sufficient for eliminating the toxic influence of stress Al. Root exudates of plants capable of producing such an organic acid that plays an important role in adaptation strategies. The high production of organic acids is associated with the formation of specific enzymes, as a response to stress Al. Allegedly the sensitive strain, the synthesis of organic acids is not adequate to chelate A
IMPLEMENTING GUESSING MEANING FROM CONTEXT PROCEDURE FOR VOCABULARY LEARNING IN JUNIOR HIGH SCHOOL IN INDONESIA
No full textAbstractVocabulary learning often implies that there is no other way of learning than to memorize the words. This research showed that guessing meaning from context procedure can accommodate students in learning new vocabulary items. Since students were not equipped with a dictionary all of the time, it is essential to seek for an alternative in learning vocabulary. One of the alternative techniques in vocabulary learning was guessing meaning from context. The purpose of the study was to investigate the implementation of the guessing the meaning from the context in junior high schools in Yogyakarta. The research participants of this study were 30 students from different classes from a junior high school in Yogyakarta, Indonesia. The researcher conducted a pre-test at the beginning and a post-test at the end of the research. The result of the pre-test and post-test showed that there was an increase of students’ vocabulary mastery. The questionnaire was used to confirm the result of pre-test and post-test comparison. The result of the questionnaire showed that guessing meaning from context procedure was helpful for the students to understand word meaning
FROM INLAND TO OUTLAND: EXPERIENCES OF NON-NATIVE EXPATRIATE TEACHERS TEACHING IN A FOREIGN CONTEXT
Get PDFThe numbers of English language learners and limited domestic English language teachers have grown exponentially in Indonesia, Thailand and Vietnam, as well as to the ASEAN region over the past decades due to the demand of globalization. Given the huge cultural and linguistic diversity among learners, educating these populations of English language learners can be a challenging but also beneficial for foreign language teachers. This study aimed to analyse the experiences of fifteen Non-native English Speaking Foreign Teachers (NNESFT) teaching in Indonesia, Thailand and Vietnam. The results of this study suggested that although teachers’ reasons in teaching English language in a foreign classroom were more extrinsic reasons rather that intrinsic and altruistic. NNESFT recognized benefits of teaching in foreign classroom, namely, financial aspects, personal development, and building cultural awareness. Meanwhile, challenges were reported include as a non-native English speaking teachers in a foreign classroom, on the part of textbooks and curriculum, and cultural differences in the classroom. Implications were discussed in light of the findings and recommendations formulated for future research directions
USE OF HAND GESTURES THROUGH DIGITAL VIDEO TO IMPROVE PHONEMIC AWARENESS AMONG YEAR 2 PUPILS
No full textPupils need phonemic awareness so that they have the ability to manipulate the individual sounds in words. However, they sometimes focused more on reading comprehension rather than recognizing the letter sounds which build the words for reading. This action research was designed to improve the pupils’ phonemic awareness by using hand gestures through digital video and it involved three cycles. The participants involved were 24 Year 2 pupils from one of the primary schools in Malaysia. Three different data collection methods used were tests, pupils’ work and observation. The findings showed there was an improvement of mean scores from 40% in Test 1 to 91% in Test 2. The pupils’ oral exercises also improved from 52.14% to 96.07%. The results from the observation checklist and notes also showed they became more aware in learning English through their increased communication and active participation in the lesson. This shows that the technique was able to help pupils to learn and remember the sounds of phonemes as they could read the words correctly. It is suggested to carry out further research to develop the pupils’ skills in phonemic awareness through body movements in addition to hand gestures
Characteristics of Soil Fertility Affecting the Rice Fields Productivity in Bogor Regency
Get PDFThe purpose of this study was to determine the parameters of soil fertility in rice fields and the effect of soil fertility on paddy productivity in Bogor Regency. This research was conducted in the districts of Cileungsi, Darmaga and Leuwiliang, Bogor Regency. The location selection was done deliberately based on the location of rice production facilities with Ciherang and Inpari varieties. Sampling was conducted at several sampling points at each location. Each sub-district was taken 8 samples or 24 in total, then analyzed in the laboratory. Data processing using multiple regression with a dummy. The results showed that the soil in Bogor Regency was generally acidic, where soil fertility characteristics with organic C content were low to moderate, nitrogen was very low to moderate, P was low to high, K was very low to moderate, CEC was moderate to high, and saturation bases (KB) are moderate to high. Soil biology, namely total bacteria, total fungi, total solvent P bacteria, Azotobacter sp., And Rhizobium sp. Are generally low to moderate. Variable characteristics of soil fertility in the form of organic C, Nitrogen (N), K2O HCl 25%, and CEC significantly influence rice productivity. Soil fertility in the three districts is almost the same and does not affect the productivity of rice fields. While the productivity of rice fields with Inpari varieties is higher than those grown by Ciherang varieties. To increase the productivity of rice fields in Bogor Regency, it is recommended to plant Inpari variety rice by applying N fertilize

Yield Evaluation and Selection of M6 Wheat Mutant adaptive to Medium Land
Get PDFWheat is a sub-tropical plant that can adapt well at altitudes of 1000 - 3000 m above sea level and requires relatively low temperatures. At this height, wheat crops in Indonesia are unable to compete with horticultural crops with higher economic value. This causes national wheat production to be very low and results in high wheat imports. Therefore, wheat varieties are needed that can grow and develop in Indonesia in the low to medium plains. The study aimed to test the adaptive mutant population descent in the middle plains to prepare multi-location tests and release of varieties. The benefit of this research is obtaining potential strains from high-temperature adaptive wheat mutants in the lowlands. This research was conducted using a randomized block design with three replications. The treatment consisted of 16 M6 Wheat mutants and four comparative varieties. The results showed that the genotypes of wheat mutants that had high production in M6 propagation in the central plains were N 350 3.7.1 (2.74 t. ha-1), N 350 3.6.2 (2.33 t.ha-1) and N 350 3.1.3 (2.26 t.ha-1). Characters that have high heritability values on M6 Number of stomata, chlorophyll index, plant height, number of tillers, productive tillers, rate of seed filling, panicle length, number of seedlings, empty percentage of florets, hollow seed weight, 1000 seed weight, and productio
