Abstract

Unbalanced panel data classified in fixed effect and random effect with one-way and two-way. Dummy variable used to determine differences the intercept on the classification individual or time units with assuming the intercept varies between individuals and time, whereas the slope is constant. For the random effects, differences in characteristics individual and time accommodated on the error component model with unknown error covariance matrix. The method used for one-way is Feasible Generalized Least Square (FGLS). Modifications ANOVA by Wallace and Hussain used for variance component estimation on the error covariance matrix. Components Estimation of variance on the error covariance matrix using the OLS residuals as components of quadratic forms and equating to expectations. In this case study the factors that affect cash dividend represented by ROI, Cash Ratio, Current Ratio, Debt Total Assets, Earning Per Share, Debt Equity Ratio and Dividend Payout Ratio in the period 2012-2017 with 36 of consumer goods manufacturing company in IDX.

Abstract

The Grand Mall Batam Development Project with number of stories 30 and 1 basement. Footing Plan of this project using bore pile. Observations are made at the project construction site for data collection for 3 months in 2018. The beams used are dimensins of B350 x 750 dimensions with a top reinforcement of 6D20 mm, 2D12 mm for center reinforcement, 3D20 mm for bottom reinforcement and D10-200 mm for diameter distance. The calculation of the beam starts with the planning data on the beam structure analysis, namely Concrete Quality 29 Mpa (K-350), Screw 500 Mpa and Plain Iron 260 Mpa. The loading on the beam is carried out in the field that work, the child beam and the main beam with details of dead load, live load, factored load. On the main reinforcement of the beam, the moment is calculated, namely the moment of the field, the moment of support and the moment of the plan. Based on the calculation of loading on the beam, the deflection value is 0.01709 m. Calculation of stirrup reinforcement on the beam where the required distance is 254.0073 mm and a distance of 200 mm is taken with an iron diameter of 10 mm. So the calculation of the main reinforcement of beam and stirrup reinforcement is in the Safe category.

Abstract

Raja Haji Fisabilillah International Airport is an airport in Tanjungpinang and it is quite high in service levels for the flow of passengers and goods. Based on the data from Airport Quality Angkasa Pura II, the passengers growth has both decreased and increased in the last 3 (three) years. In 2015, there were 258,936 people in total and has decreased to 246,828 people in 2016 and increased again in 2017 by 351,688 people. Therefore, it is necessary to evaluate the terminal of Raja Haji Fisabilillah International Airport. The methods used are observation and forecasting using the SARIMA. The evaluation and analysis results show that the terminal of Raja Haji Fisabilillah International Airport still meets the applicable standards and passenger movements for the next year 2020 indicate that all equipment facilities for the needs of terminal passengers of Raja Haji Fisabilillah International Airport are still adequate.

Abstract, Raja Haji Fisabilillah International Airport is an airport in Tanjungpinang and it is quite high in service levels for the flow of passengers and goods. Based on the data from Airport Quality Angkasa Pura II, the passengers growth has both decreased and increased in the last 3 (three) years. In 2015, there were 258,936 people in total and has decreased to 246,828 people in 2016 and increased again in 2017 by 351,688 people. Therefore, it is necessary to evaluate the terminal of the airport. The methods are used observation and forecasting is SARIMA. The evaluation and analysis results show that terminal of this airport still meet the applicable standards and passenger movements for the next year 2020 indicate that all equipment facilities for the needs of terminal passengers of Raja Haji Fisabilillah International Airport are still adequate. Keywords: SARIMA, Forecasting, Passenger, Airport. Abstrak, Bandar Udara Internasional Raja Haji Fisabilillah merupakan bandar udara yang ada di Kota Tanjungpinang dan merupakan bandara yang cukup tinggi dalam tingkat pelayanan terhadap arus penumpang maupun barang. Berdasarkan data dari Airport Quality Angkasa Pura II bahwa pertumbuhan penumpang mengalami penurunan dan peningkatan dalam 3 (tiga) tahun terakhir, tercatat data tahun 2015 sebanyak 258.936 orang, tahun 2016 menurun menjadi 246.828 orang dan meningkat kembali di tahun 2017 sebanyak 351.688 orang. Maka diperlukan evaluasi terhadap terminal penumpang dari bandara ini. Metode yang digunakan adalah observasi dan peramalan dengan SARIMA. Hasil evaluasi dan analisis menunjukkan bahwa terminal penumpang Bandar Udara Internasional Raja Haji Fisabilillah masih memenuhi standar dan syarat yang berlaku dan pergerakan penumpang untuk tahun mendatang 2020 menunjukkan seluruh fasilitas peralatan pelayanan kebutuhan terminal penumpang Bandar Udara Internasional Raja Haji Fisabilillah masih memadai. Kata kunci: SARIMA, Peramalan, Penumpang, Bandara.
