Abstract

Inflation is one of the important indicators in analyzing the economy of a country. One aspect that could detect the stability of Rupiah, the Indonesian Currency, is reflected in low inflation and stability. Furthermore, in determining a country’s rate of inflation for a period ahead, time series forecasting could be used as one alternative. Forecasting is a statistical method which plays an important role in delivering a decision. Forecasting the future based on past information from a variable or past mistakes is called time series. The inflation rate is one of financial data, which tends to be non linear and volatile. Therefore, neural network forecasting is used.

Abstract

Geometri analitik adalah suatu cabang ilmu matematika yang merupakan penggabungan antara aljabar dan geometri. Hal ini berarti untuk dapat memahami aljabar dapat menggunakan gemotri ataupun sebaliknya. Berdasarkan pengamatan peneliti terhadap mahasiswa yang mengambil mata kuliah geometri analitik, mahasiswa sering mengalami kesulitan untuk memahami materi. Penyebab utamanya adalah mahasiswa kurang antusias mengikuti pembelajaran, daya kreativitasnya rendah, dan bersikap acuh tak acuh sedangkan materi geometri analitik mentut keaktifan siswa untuk lebih memahami konsep aljabar secara geometrik. Hal ini menunjukkan bahwa proses pembelajaran secara konvensional yang biasa dilakukan tidak mampu mendorong mahasiswa untuk menggunakan daya pikirnya secara optimal, akibatnya mahasiswa menjadi kurang aktif dan proses pembelajaran menjadi kurang efektif. Untuk meningkatkan kemampuan mahasiswa dalam mengaitkan konsep-konsep aljabar menggunakan geometrik, maka dalam penelitian ini dilakukan pembelajaran dengan menggunakan pendekatan PAIKEM

AbstractDJP continues to optimize the collection of tax returns by facilitating a technology-based tax service system, one of which is e-filing that has been running since 2016. However, e-filing turned out to have less influence on the delivery of Tax Returns (SPT) as reflected in the electronic SPT monitoring data that only met 78% of the 2017 target. This is caused by various problems that arise during the use of e-filing such as individual technology capabilities, loss of efin, forgetting DJP Online account passwords to lack of awareness about the importance of submitting SPT. Problems encounter during the use of e-filing are the basis for evaluating the continued use of e-filling in Palembang. The development of a conceptual model was conducted to evaluate the sustainability of the use of e-filing. The development of a conceptual model basically has a scarcity of supporting theories used and has a complex model. To overcome this problem, Partial Least Squares (PLS) Structural Equation Model (SEM) could be applied to. The results of data analysis found that information quality and service quality did not have a positive influence on the sustainability of the use of e-filing and the level of correlation between information quality, system quality, service quality, and individual ability was still small towards the sustainability of the use of e-filing. The findings of this research are very important for the KPP Pratama in Palembang to analyze the sustainability of the use of e-filing that has been proven empirically, multidimensional and in a specific context. This knowledge could be used as a reference to improve overall quality of taxation for the sake of sustainable use of e-filing.Keywords : SPT, e-filing, PLS SEMAbstrakDJP terus berupaya mengoptimalkan pengumpulan Surat Pemberitahuan Tahunan (SPT) pajak dengan memfasilitasi sistem pelayanan perpajakan berbasis teknologi, salah satunya adalah e-filing yang telah berjalan sejak tahun 2016. Namun, e-filing ternyata kurang berpengaruh terhadap penyampaian SPT yang tergambar pada data hasil monitoring SPT elektronik yang hanya memenuhi 78% dari target sasaran tahun 2017. Hal ini disebabkan oleh berbagai masalah yang muncul selama pemanfaatan e-filing seperti kemampuan teknologi individu, kehilangan efin, lupa password akun DJP Online hingga kurangnya kesadaran tentang pentingnya penyampaian SPT. Permasalahan selama penggunaan e-filing menjadi dasar untuk melakukan evaluasi terhadap keberlangsungan penggunaan e-filling di Palembang. Pengembangan model konseptual dilakukan untuk mengevaluasi keberlanjutan penggunaan e-filing. Pengembangan model konseptual pada dasarnya memiliki kelangkaan teori-teori pendukung yang digunakan dan memiliki model yang kompleks. Untuk mengatasi masalah ini dapat menggunakan Partial Least Squares (PLS) Structural Equation Model (SEM). Hasil analisis data mendapatkan temuan bahwa kualitas informasi dan kualitas layanan tidak memiliki pengaruh positif terhadap keberlanjutan penggunaan e-filing dan tingkat korelasi antara kualitas informasi, kualitas system, kualitas layanan, dan kemampuan individual masih kecil terhadap keberlanjutan penggunaan e-filing. Temuan peneliti ini sangat penting bagi pihak KPP Pratama kota Palembang untuk menganalisa keberlanjutan penggunaan e-filing yang telah dibuktikan secara empiris, multidimensional dan konteks yang spesifik. Pengetahuan ini dapat dapat menjadi acuan untuk meningkatkan kualitas secara keseluruhan demi keberlanjutan penggunaan e-filing.Kata kunci : SPT, e-filing, PLS SEM,

Abstract

In this article, we try to design the architecture of a smart notification system using an Android gadget for academic notification in college. Academic notification in colleges now utilizes bulletin boards and online media such as websites or social media. The problem faced is the high cost and resources required to deliver the academic notification. Another problem is whether the information delivered can be right to the students who need it. We proposed the architecture of a smart notification system that can reduce the cost, and the information delivered can be right on target to the students in need.

Abstract

DGT (Directorate General of Taxation) continues to optimize the collection of annual tax returns by facilitating technology-based tax service systems, one of which is e-filing that has been running since 2016. However, e-filing turned out to have less influence on the delivery of annual tax returns as reflected in the electronic annual tax returns monitoring data that only met 78% of the 2017 target. This is caused by various problems that arise during the use of e-filing such as individual technology capabilities, loss of efin, forgetting DGT Online account passwords to lack of awareness about the importance of submitting annual tax returns. Problems encounter during the use of e-filing are the basis for evaluating the continued use of e-filing in Palembang. The development of a conceptual model was conducted to evaluate the sustainability of the use of e-filing. The development of a conceptual model basically has a scarcity of supporting theories used and has a complex model. To overcome this problem, Partial Least Squares (PLS) Structural Equation Model (SEM) could be applied to. The results of data analysis found that information quality and service quality did not have a positive influence on the sustainability of the use of e-filing and the level of correlation between information quality, system quality, service quality, and individual ability was still small towards the sustainability of the use of e-filing. It could be concluded that the quality of information and service provided by DGT has the opposite effect that does not even influance the sustainability of e-filing usage. However, the quality of the system and the ability of individuals to give effect to e-filing usage in reporting in reporting annual tax returns. Therefore, DGT is expected to improve the quality of the system of e-filing expecially in the function of e-filing, ease of use, usefullness of e-filing in reporting annual tax return. In additory it is necessary to carry out socialization and training on e-filing to improve the ability of individuals to report online their annual tax report. The findings of this research are very important for the Tax office in Palembang to analyze the sustainability of the use of e-filing that has been proven empirically, multidimensional and in a specific context. The result of the study could be used as a reference to improve overall quality of taxation for the sake of sustainable use of e-filing.

Abstract

The exchange rate is determined by the demand and supply relationship of the currency. If the demand for a currency increases, while the supply remains or even decreases, then the exchange rate will rise vice versa. The ups and downs of exchange rates on the money market indicate the magnitude of the volatility that occurs in the currency of a State against the currencies of other countries. The volatility phenomenon indicates difficulty in analyzing the exchange rate. Increasing volatility indicates an even greater movement of currency exchange rates even if currency exchange rates experience extreme volatility resulting in economic instability both from the micro and macro sides. The high volatility seen from the pattern of price movements that occur in financial markets, and the impact that can be generated from the high volatility data is the error that will have a variance that is not constant. That is, a relatively high data variability at a time indicates the presence of heteroscedasticity. Heteroscedasticity can lead to errors in drawing a conclusion to the estimated model obtained. Therefore, we need a model that is able to solve the problem that is Generalized Autoregressive Conditional Heteroscedasticity (GARCH) model in order to get more accurate estimation model to estimate exchange rate. From the simulation result, all data contain the volatility seen from the result of heteroscedasticity test, and obtained estimation model for all data.
