Soil Characteristics on Sustainable Food Agriculture Land (LP2B) In Sawerigadi Sub-District, Muna Barat Regency
Get PDFThe research was conducted in Sawerigadi Subdistrict on Sustainable Food Agricultural Land (LP2B) consisting of five profiles. The research objectives were to determine soil characteristics in physics, chemistry, biology, and to determine the level of soil fertility on it. The research method that is; 1) Land Survey, 2) Research implementation includes the both preparation stage and data collection stage (field implementation), 3) Soil analysis includes analysis of physics, chemistry and biology. Observation and carried out soil sampling were by making soil profiles at the each point. The results of the observation physical properties from the five profiles were almost the same, which had a reddish yellow to brownish yellow color with the texture of loam, clay, clay loam to silty clay. Soil structure is angular blocky and rounded blocky and has a slightly sticky to very sticky consistency. The results of laboratory analysis of the five research profiles have slightly acidic to neutral pH, very low to low C-Organic and NTotal, very low to moderate CEC, very low to very high alkali saturation, P-available is low to very high, K-available is low to moderate, and very low to high base cations (Mg, Ca, Na, K). The value from the results of laboratory analysis of the five profiles at each layer tended to decrease with soil depth. The biological characteristics of the five research profiles are related to macro and micro activity of soil fauna, a little to a lot, the existence of macro and micro activity of soil fauna depending on vegetation conditions on the soil surface. The soil fertility level of the five research profile is in the low to medium categor

The research was performed by purified the endophytic bacteria isolate, the antagonism test as an antibacterial against Staphylococcus aureus also performed, and the data obtained were analyzed descriptively Keywords:  Endophytic Bacteria, Pimpinella pruatjan Molk., Staphylococcus aureu
Value Added Analysis of The Corn Supply Chain As Feed For Poultry In the Sub-District, Contact the City of BauBau
Get PDFThis study aims to: (1) assess the performance trajectory of the corn supply chain for the needs of the animal feed industry. (2) analyze the added value of the animal feed maize marketing system. using the census sampling technique, where the entire population is sampled because the population is small or less than 35 respondents, so the sample in this study was 30 respondents, i.e. all actors in the chain of corn supply. The technique used to obtain both primary and secondary data in this study was carried out through face-to-face interviews using questionnaires. descriptively to answer the problems and objectives. At the same time, the added value in the animal feed maize marketing system uses the modified Hayami method which will be analyzed to address the second problem and research objective. The results showed that: (1) Supply chain performance consists of a single line, starting from corn collectors and selling to wholesalers. Then the feed company buys from wholesalers as the main supplier of corn. The results of animal feed will be sold to retailers and marketed by end consumers. (2) The value added process created in the animal feed sector which provides added value for corn is Rp. 7,500 per kg of animal feed and the profit earned in the company is Rp. 2,300, - per kg of feed, then the total profit for a month of production is Rp. 5,750,000

The result is most of community that effected by lahar disaster has income increase by Rp12,500 until Rp100,000 per-day and the community can use the material lahar that deposit around Putih River by selling it as building material, and then they can build a building according Contractor, BPS, and Community standard.Â
Making Connections: A Metacognitive Teaching Strategy in Enhancing Students’ Reading Comprehension
No full textReading comprehension skill is crucial for success beyond academic endeavor. However, even academic success can never be possible when a student does not understand the importance of developing good reading comprehension. Using one-group pretest–posttest research design, the study explored the effect of making connections as a metacognitive teaching strategy to enhance the students’ reading comprehension. Purposively selected college students were given assessments and intervention. Based on the data gathered from the pretest and posttest, findings revealed that application of metacognitive teaching strategy, making connections has a positive effect on enhancing the students’ level of reading comprehension as indicated by an increase from average to very high level. The six levels of reading comprehension which were the literal, inferential, appreciative, critique, and evaluative also showed improvement. Results of the Metacognitive Awareness Reading Strategies Inventory (MARSI) indicated that students were unconsciously using Global reading, Problem-solving, and Support reading strategies. Focus group discussion revealed factors that affect the reading comprehension such as interest, teaching styles, and language. The study suggested the important role that educators play in maximizing the benefits of making connections and making use of any other metacognitive strategy towards developing higher level of comprehension leading to academic success
