Abstract. Quantitative forecasting methods are divided into three types, its time series methods, causal methods, and combination methods of time series and causal methods (Makridakis, 1999). The time series method is a method that predicts the future based on the past value of a variable or past errors. One of the time series methods that is being developed and commonly used is the ARIMA method. Although the calculation process is quite complex, the ARIMA method will give better results than other forecasting methods, because this method does not ignore time series rules such as stationary testing, parameter estimation, and diagnostic testing. Unlike the ARIMA method, Grey System Theory does not require all historical data, but only requires a minimum of four historical data and in the same interval. In this study, we will discuss the Forecasting of the Number of Railway Passengers in the Java Region (Jabodetabek and Non Jabodetabek) using the ARIMA Method and Grey System Theory. From the modeling that has been done, it is found that the GM model (1,1) is the most suitable model to be used to predict the number of train passengers in the Java region.

Abstrak. Metode peramalan kuantitatif dibagi menjadi tiga jenis, yaitu metode deret waktu, metode kausal, dan metode kombinasi metode deret waktu dan metode kausal (Makridakis, 1999). Metode deret waktu adalah sebuah metode yang memperkirakan masa depan berdasarkan nilai masa lalu dari suatu variabel atau kesalahan masa lalu. Salah satu metode deret waktu yang sedang berkembang dan umum digunakan adalah metode ARIMA. Meskipun proses perhitungannya cukup kompleks, metode ARIMA akan memberikan hasil yang lebih baik dari metode-metode peramalan lainnya, karena metode ini tidak mengabaikan kaidah-kaidah pada deret waktu seperti pengujian stasioner, penaksiran parameter, dan pemeriksaan diagnostik. Berbeda dengan metode ARIMA, Grey System Theory tidak memerlukan seluruh data historis, namun hanya membutuhkan minimal empat data historis dan dalam interval yang sama. Dalam penelitian ini akan dibahas Peramalan Jumlah Penumpang Kereta Api Wilayah Jawa (Jabodetabek dan Non Jabodetabek) menggunakan Metode ARIMA dan Grey System Theory. Dari pemodelan yang telah dilakukan diperoleh hasil bahwa model GM (1,1) menjadi model yang paling cocok digunakan untuk meramalkan jumlah penumpang kereta api wilayah Jawa.

Published: September 2022

Abstract. Outliers are datums that are far from other datums. Outliers arise as a result of unusual events that may be very important and need to be investigated further. Outliers are usually found in data that has daily characteristics such as stock data. With this outlier, the T2 Hotelling control chart used to control the average vector shift becomes insensitive to changes in the process. This thesis discusses the T2 Hotelling control chart for the Minimum Volume Ellipssoid (MVE) estimator which is not affected by outliers. This control chart is then applied to the daily stock index control of  PT X and the Joint Stock (JCI) simultaneously. The results of the tests carried out show that the T2 Hotelling control chart for the MVE estimator is more effective in detecting outliers, namely there are 13 data that are out of control with a UCL value of 5.5025.

Published: September 2022

Abstract. PT X has been processing residual tin ore (SHP), land mining and marine mining with a grade of <70%. In order to increase the levels of tin and its associated mineral products to high grade >70% as a requirement for the smelting stage. Tin ore will be analyzed to determine the % content of the sample. Assay analysis can be carried out using a microscope analysis process, unit coefficient balance and chemistry. Microscopy analysis method obtained an average percentage of Sn content of 58.79%, UC Balance analysis of 66.92% and chemical analysis of 58.91%. The level of accuracy produced by the UC Balance analysis tool is the biggest influence on the % of Sn content produced, because it only weighs the specific gravity of cassiterite. The other factors that affect the high error rate generated by the UC Balance analysis are the quality, size, and density of minerals. Meanwhile, the microscope analysis experienced a decrease in the level of accuracy because it was influenced by the quality of the sample and the accuracy of the analyst in distinguishing the types of minerals in each sample. Associated minerals such as ilmenite, zircon, monazite, pyrite and quartz affect the results of the Sn content that will be obtained. The recommended limit for the effective value of microscopy analysis is > 60% and UC Balance analysis is > 70% based on the results of % overall levels.

Abstrak. PT X telah melakukan pengolahan bijih timah sisa hasil pengolahan (SHP), penambangan darat dan penambangan laut dengan kadar <70%. Guna meningkatkan kadar timah dan produk mineral ikutannya menjadi high grade >70% sebagai syarat menuju tahap peleburan. Biji timah akan dianalisis untuk mengetahui % kadar sampel. Analisis kadar dapat dilakukan menggunakan proses analisis mikroskop, unit coeficient balance dan kimia. Metode analisis mikroskop mendapatkan hasil ratarata persen kadar Sn sebesar 58,79 %, analisis UC Balance sebesar 66,92 % dan analisis kimia sebesar 58,91 %. Tingkat ketelitian yang dihasilkan oleh alat analisis UC Balance menjadi pengaruh terbesar terhadap % kadar Sn yang dihasilkan, karena hanya menimbang berat jenis kasiterit saja. Adapun faktor lain yang mempengaruhi tingginya tingkat kesalahan yang dihasilkan analisis UC Balance yaitu kualitas, ukuran, berat jenis mineral. Sedangkan pada analisis mikroskop mengalami penurunan tingkat ketelitian karena dipengaruhi oleh kualitas sampel dan ketelitian juru analis dalam membedakan jenis-jenis mineral pada setiap sampel. Mineral ikutan seperti ilmenite, zircon, monazite, pyrit dan kuarsa mempengaruhi hasil nilai kadar Sn yang akan didapatkan. Rekomendasi batas nilai efektif analisis mikroskop > 60 % dan analisis UC Balance > 70 % berdasarkan dari hasil % kadar keseluruhan.

New Approach to Observer-Based Finite-Time H∞ Control of Discrete-Time One-Sided Lipschitz Systems with Uncertainties
Authors: Tang Xinyue , Dong Yali , Liu Meng
Published: September 2022

This paper investigates the finite-time H∞ control problem for a class of nonlinear discrete-time one-sided Lipschitz systems with uncertainties. Using the one-sided Lipschitz and quadratically inner-bounded conditions, the authors derive less conservative criterion for the controller design and observer design. A new criterion is proposed to ensure the closedloop system is finite-time bounded (FTB). The sufficient conditions are established to ensure the closed-loop system is H∞ finite-time bounded (H∞ FTB) in terms of matrix inequalities. The controller gains and observer gains are given. A numerical example is provided to demonstrate the effectiveness of the proposed results.

Abstract. Sermons by Lay Preacher (LP) in Pentecostal circles are often judged to depart from arbitrary interpretations because they involve personal experience in the biblical text understanding. However, Hans-Georg Gadamer has promoted the fusion of horizon in his hermeneutic ideas, which seems to be in line with LP's practice of interpreting biblical texts. Thus, the aim of this study is to demonstrate how far fusion horizon in Gadamer's hermeneutics is applied by LP. The method used in this study is a qualitative method with a structured literature study approach and phenomenology to a LP, and church pastors who have experience being served by the LP. The results showed that the process of interpreting the biblical text by LP is in line with horizon fusion in Gadamer's hermeneutics, where LP's spiritual experience plays a role in widening the horizon in understanding the biblical text.Abstrak. Khotbah oleh Lay Preacher (LP) di kalangan Pentakostal seringkali dinilai berangkat dari penafsiran secara sembarangan karena melibatkan pengalaman pribadi dalam proses memahami teks Alkitab. Namun demikian, Hans-Georg Gadamer pernah mencetuskan fusi horison dalam gagasan hermeneutiknya, yang nampaknya sejalan dengan praktik interpretasi teks Alkitab oleh LP. Dengan demikian, tujuan studi ini adalah untuk menunjukkan sejauh mana fusi horison dalam heremeneutika Gadamer tersebut diterapkan oleh LP. Metode yang digunakan dalam penelitian ini adalah metode kualitatif dengan pendekatan studi literatur terstruktur dan fenomenologi kepada seorang LP, dan gembala jemaat yang memiliki pengalaman dilayani oleh LP. Hasil penelitian menunjukkan proses interpretasi teks Alkitab oleh LP sejalan dengan fusi horison dalam hermeneutika Gadamer, di mana pengalaman spiritual LP berperan memperlebar horison dalam pemahaman teks Alkitab.

Pharmaceutical regulation, pricing, coverage and policy reform in the United States of America
Authors: SOCAL Mariana P. , ORTIZ Juliana A. , GARCIA Fabricio , PINGRET-KIPMAN Daniella
Published: September 2022

The United States (US) is the largest economy in the world and the largest pharmaceutical market, accounting for 40% of the global expenditure on pharmaceuticals and almost half of the global pharmaceutical pipeline. This review describes prescription drug regulation, pricing and coverage in the US and provides perspectives for policy reform. With an unregulated market-based pricing system for drugs, the US pays on average 3 to 4 times higher prices for branded prescription drugs than other industrialized countries. Challenges posed by rising drug prices create affordability problems that threaten the American population’s health as well as the sustainability of the US healthcare system. The US stands out as the country with the highest health expenditure per capita, at about 17% of its gross domestic product, and with pharmaceuticals representing over 12% of the total health expenditure. Health coverage is strongly dependent on employmentbased private insurance, with government programs like Medicare and Medicaid providing coverage to older and poorer populations, respectively. Coverage for outpatient prescription drugs is included in most, if not all, private health insurance plans and government programs. Although some drug pricing policy reforms have been proposed in recent years, no major nationwide initiatives have been successful in the US thus far. High drug prices might not only impact the US care system’s efficiency, but can also have a ripple effect to other countries like Brazil that use the US for external reference pricing, even if those countries may have other price regulation mechanisms in place. This is particularly important for new therapies for which no other international prices may be available in the global market besides the one from the US. The growing budgetary pressures from rising drug prices underscore the need for US drug pricing reform and highlight the need for global pricing mechanisms that can help ensure early access to new technologies at fairer prices.
