Abstract

This study aims to prove and analyze (1) the effect of gross domestic product on the realization of PBB in West Sumatra. (2) the amount of land to the realization of PBB in West Sumatra (3) building area to the realization of PBB in West Sumatra. (4) inflation on the realization of PBB in West Sumatra. (5) together with GRDP, total land area, building area and inflation towards the realization of PBB in West Sumatra. This type of research is quantitative research. In this study, the data used is panel data from 2015 – 2019 in 19 districts and cities in West Sumatra. The method used is a panel regression model with the selected panel regression estimation model, namely the Random Effect Model (REM.) The results obtained show that: (1) GRDP is not significant to the realization of PBB in West Sumatra (2 land area has a significant effect on the realization of PBB in Sumatra). West Sumatra (3) building area has a significant effect on PBB realization in West Sumatra (4) inflation is not significant on PBB realization in West Sumatra Together with GRDP, land area, building area and inflation have a significant effect on PBB in West Sumatra. the results of the study that the increasing number of people who own land and inflation is still under control, it actually encourages the realization of the payment of Land and Building Taxes in West Sumatra, therefore by observing the factors that encourage changes in the realization of PBB payments can provide a solution in the form of policies for local government to improve the actual value of land and building tax payments in 19 districts and cities in West Sumatra.

Abstract

PT Mandiangin Batubara targets overburden stripping production in June 2022 of 184,571 bcm in the highwall bottom area of pit A, while for the realization of the ability of the SANY SY500H Excavator, the resulting production is only 121,347 bcm / month. The non-achievement is also due to the low effective working time which is only 367.76 hours / month and 358.74 hours / month from the available time of 641 hours / month.Efforts that can be made to analyze based on the problem are in the form of analysis using the overall equipment effectiveness method and determining losses based on the six big losses of equipment. Then proceed with grouping the root cause of the problem of non-achievement of production, namely with the Fishbone diagram. From the results of the analysis based on the six big losses, it was obtained that the highest losses occurred in Equipment Failure Losses of 42.62% and 44.03% respectively. After repairing the loss time, the total production of Overburden stripping was 221,925 bcm which means that the results of these improvements can exceed the production target by increasing the OEE value of the digging and loading equipment by 48% and 54% respectively.

Abstract

A person’s ability to solve problems was a very important aspect that must be possessed by students’ in learningmathematics because it wa one of the goals of learning mathematics. However, result of observation and interviews in the class X MIPA SMAN 7 Padang shows that students’mathematical problem solving ability was still low. It was cause by students’ did not involvment in learning process and they didn’t accustomed to solve non routine problems. Therefore, to improvestudents’ mathematical problem solving ability required anappropriate strategy in learning activity. One of learning models that can be used is guided inquiry model. Purpose of study was to determine students’ mathematical problem solving ability that usingguided inquirylearning model and compare it with students’ who learn with conventional learning in class X MIPA SMAN 7 Padang year lesson 2017/2018. Based on data analysis at a = 0,05 by doing t’-test,it is obtained Pvalue = 0,000, because P-value < a then????0 rejected. This means that students’ mathematical problem solving ability who learning by applying guided inquiry model is better than conventional learning in class X MIPASMAN 7 Padang year lesson 2017/2018.Keywords – conventional learning, guided inquiry learning model, mathematical problem solving ability.
