Abstract

Overall Equipment Effectiveness (OEE) is a comprehensive measure to identify the level of productivity and performance of machines/equipments. Conventional approaches to OEE data processing, such as using Microsoft Excel, have limitations. Consequently, the data processing process becomes less efficient and prone to human error. This study aims to examine the application of OEE in the Manufacturing Industry, measurable performance gaps between conventional and real-time approaches. The methodology used in this study was based on a synthetic literature review to evaluate the effectiveness of both OEE approaches based on existing studies. The transition of OEE from mere calculations to dynamic, real-time, and integrated systems is a direct response to the increasing complexity and competitiveness of the modern manufacturing environment. This study can be used to identify areas for future development and as a reference for further research to provide a guide to OEE practitioners in implementing improvements.

Abstract

Industrial growth and the increasing number of transportations cause the need for oil to increase. The increasing need for oil is directly proportional to the waste produced, namely used oil. Used oil waste can be a replacement fuel, which is produced quite large every year. This research used a mixture of used oil and Pertamina Dex used as a modified diesel engine fuel. The purpose of this study was to analyze the exhaust emissions produced by modified diesel engines. The research was conducted by varying the percentage of the mixture of used oil and Pertamina Dex, namely the percentage of a mixture of P10 (90% used oil and 10% Pertamina Dex), P20 (80% used oil and 20% Pertamina Dex) and P30 (70% used oil and 30% Pertamina Dex). Tests on the calorific value of fuel and exhaust emissions, which are varied based on the power load at idle (0 W), 1,000 W and 2,000 W. The test results showed that the calorific values of fuel P10, P20 and P30 were 44,191 kJ/Kg, 48,648 kJ/Kg and 50,074 kJ/Kg respectively. From this research it is known that the best fuel mixture of P30 with a loading power of 0 W, which emits a value of CO of 0.03%, CO2 of 2.32%, and HC of 34.86%. The results showed that the P10, P20 and P30 fuels met the exhaust emission quality standards according to the applicable regulations where the resulting opacity emissions did not exceed 40%.

Abstract

Tujuan dari penelitian ini adalah untuk menguji data secara empiris mengenai faktor-faktor yang mempengaruhi agresivitas pajak pada perusahaan manufaktur yang terdaftar di Bursa Efek Indonesia. Variabel dari penelitian ini terdiri dari Leverage, Likuiditas, Intensitas Modal, Komisaris Independen, Intensitas Persediaan dan Profitabilitas. Populasi yang digunakan dalam penelitian ini adalah perusahaan manufaktur yang terdaftar di Bursa Efek Indonesia (BEI) pada tahun 2017-2019. Penentuan sampel menggunakan purposive sampling method dan terdapat 82 perusahaan yang telah memenuhi kriteria sampel. Hipotesis yang digunakan peneliti untuk melakukan penelitian yaitu menggunakan analisis regresi berganda. Hasil dari penelitian ini menunjukkan bahwa Profitabilitas memiliki pengaruh terhadap Agresivitas Pajak. Sedangkan Leverage, Likuiditas, Intensitas Modal, Komisaris Independen, dan Intensitas Persediaan tidak memiliki pengaruh terhadap Agresivitas Pajak. Kata kunci: Agresivitas Pajak, Leverage, Likuiditas, Intensitas Modal, Komisaris Independen, Intensitas Persediaan, Profitabilitas

Abstract

Tax plays a crucial role as a primary instrument in supporting national development, serving as one of the main pillars of state revenue. Among the various tax instruments, Income Tax (PPh), particularly Article 23 (PPh 23), holds significant importance because it governs the withholding of tax on income derived from capital, services, rent, and certain types of rewards or appreciation. The implementation of PPh 23 is intended to ensure fairness, expand the tax base, and prevent tax evasion through third-party withholding mechanisms. However, in practice, challenges remain regarding the effectiveness and compliance of PPh 23, especially due to differing interpretations of taxable objects and the lack of awareness among taxpayers. To address these issues, the tax amnesty policy has emerged as an essential fiscal instrument aimed at improving voluntary compliance, expanding the taxpayer database, and strengthening the legal construction of PPh 23. Indonesia has previously implemented this policy through Law Number 11 of 2016 concerning Tax Amnesty, which provided an opportunity for taxpayers to disclose unreported assets with the promise of certain benefits and legal certainty. This study employs a normative legal research method with a statutory and conceptual approach to analyze the regulatory framework of Income Tax Article 23 in relation to tax amnesty. The objective is to explore how tax amnesty contributes to enhancing taxpayer compliance and reinforcing the legal certainty of PPh 23 enforcement within Indonesia’s tax system. Keywords: Construction, Tax Amnesty, Income Tax Article 23
