How Technology Facility to Improve Numeracy in Riau Province
No full textThe increase in numeracy in Indonesia depends on the facilities' quality at schools. This study aims to evaluate the technology facilities to improve the numeracy ability of students in Riau Province. The district to be the participant was Junior high schools of Dumai District. The research participant was teachers and students. The collection data techniques were interviews, observation, and documentation. The key instrument in this research was the researchers that gave questions to participants to get data about how the technology facility improves the numeracy of Students at Dumai District. The data analysis technique used in this research was analysis proposed by Creswell (2014). Results show that many facilities to increase numeration are still bad. Technology to improve students’ numeracy is not yet adequate because Dumai must improve public facilities such as highways, Harbor, markets and etc. The government is limiting the budget to help schools
Analysis of Fluid Flow Characteristics Across the Darrieus Turbine in Irrigation Channels: ANALISA KARAKTERISTIK ALIRAN FLUIDA MELINTASI TURBIN DARRIEUS PADA SALURAN IRIGASI
Get PDFThis study simulated the characteristics of the fluid flow that passes through the Darrieus turbine before installation and testing were carried out. The purpose of knowing the flow characteristics can determine the profile and position of the maximum speed so that the design and placement of the turbine can be improved. The research method was carried out using dynamic fluid computational simulations in three-dimensional form with steady state conditions, discretization using second-order, with convergent conditions when it reached 10-6. The simulation results show that the position of the flow above the turbine had the lowest value because the fluid flowed relatively without disturbance which caused the velocity to had a value almost the same as the incoming fluid velocity. The fluid velocity increased when it was in line 2 and line 3 or across the turbine. This was due to the turbulence generated by the rotation of the turbine. While the speed on line 4 or below the turbine had a lower value than line 2 and line 3. This was due to the position below the turbine so that the turbine rotation did not have an impact on speed. At the four line positions the velocity increased at Y=0.7 m or when the fluid hits the turbine. This increase in fluid velocity was expected to turn the turbine. The results also included the flow distribution in the form of a streamline in several positions where the flow that was in contact with the channel wall had a low velocity value due to friction with the wall

Get PDFThis research was conducted at the experimental farm of the Faculty of Agriculture, Riau Islamic University, Pekanbaru during 5 months, starting from October 2019 to February 2020. The study used a Factorial Completely Randomized Design by using two factors. The first factor was titonia compost (T), consisting of 4 levels, namely 0, 0.5, 1.0, and 1.5 kg/plot and the second factor was young coconut coir liquid waste (S), consisting of 4 levels, namely 0, 100, 200, and 300 ml/plant so that 16 treatment combinations were obtained with 3 replications. Parameters observed were harvest age, plant height, number of branches, number of leaves, wet weight, and leaf weight. The data were analyzed using statistics and continued with the Honest Significant Difference Test (BNJ) at 5%. The results showed that the interaction of titania compost and young coconut coir wastewater affected harvest age, plant height, number of branches, wet weight, and dry weight with the best combination treatment of the application of titania compost was 1.5 kg/plot and the dose of young coconut coir wastewater was 200 ml/plant. The main effect of titania compost was significant on all observation parameters with the best treatment of titania compost at 1.5 kg/plot. The main effect of young coconut coir liquid waste was real on all observation parameters with the best treatment of 200 ml/plant

Get PDFBorer pest of corn cobs (Helicovepa armigera Hubner) is a major pest of corn. Pest control can be done using plant-based insecticides from paitan leaf extract (Tithonia diversifolia A. Gray). This study aims to obtain the best concentration of paitan leaf extract in controlling corn cob borer Helicoverpa armigera. The study was conducted at the Plant Pest Laboratory of the Faculty of Agriculture, University of Riau. The research was carried out using a completely randomized design (CRD), consisting of 5 treatments and 4 replications. The treatments used were several concentrations of paitan leaf extract, namely 0 gl-1, 25 gl-1, 50 gl-1, 75 gl-1and 100 gl-1. Parameters observed were initial death, lethal time 50, lethal concentration (LC50 and LC95), daily mortality, and total mortality. data. Data were collected from daily mortality and then descriptively analyzed and displayed graphically. Data lethal concentration (LC50 and LC95) were analyzed probit using the POLO-PC program, while other data such as initial death, total mortality, and lethal time (LT50) were analyzed with analysis of variance. Data from the variance analysis with significant effect will be continued using the smallest significant difference (LSD) test at the 5% level. Results showed that the application of paitan leaf extract with a concentration of 100 gl-1 water was able to control H. armigera with mortality of 55.00%. The proper concentration to lead mortality of 50% of larvae H. armigera was 10.3% or equal to 103 gl-1 of water of paitan leaf extract. Meanwhile, the proper concentration to lead mortality of 95% of larvae population H. armigera was 44.7% or equivalent to 447 gl-1 water of paitan leaf extract

Get PDFThe purpose of this study is to determine the effectiveness of using young coconut water as an alternative material for masculinizing guppy fish through different immersion times on guppy fish larvae. This research was carried out for 50 days starting from October 25 to December 14, 2020, at the Fish Seed Center (BBI) of the Islamic University of Riau Pekanbaru. The method in this study used a completely randomized design (CRD) method with five treatments and three replications. The treatments used were soaking time of 8 hours with doses using hybrid coconut water, namely: P0: without using coconut water, P1: 50 ml, P2: 100 ml, P3: 150 ml, and P4: 200 ml. The experimental treatments were carried out on guppy fish (Poecilia reticulata) larvae. The containers used were 15 units of jars with a capacity of 10 liters which was filled with treatment media with a stocking density of 15 fish/jar. Based on the results, it was found that the highest male sex direction in guppies was in treatment P4 with a dose of 200 ml with a soaking time of 8 hours with the number of males produced at 94% and the lowest was in treatment P0 without using a dose of young coconut water which was only produced 37% males with a very low survival rate. Analysis of variance showed that F count (2.59) < F table 0.05 (3.48) at the 95% accuracy level, where different doses of masculinization of guppies (Poecilia reticulata) were not significantly different. Climatic data in the form of temperature was 28-32 0C, pH 5-7 and DO 5,7-8,20 mg/l
