Abstract

Many cases of multidrug-resistant (MDR) bacterial infections are caused by Klebsiella pneumoniae (K.pn), an infectious disease bacterium. Hospital inpatients can be exposed to this occurrence; MDR has transformed 26.96% of infections at Klaten Hospital into highly infectious biofilms, while 54.49% of infections have produced biofilms. Approximately 80% of bacterial illnesses resistant to antibiotics are caused by biofilm-forming bacteria. To reduce biofilm formation, antibacterial compounds, one of which comes from natural products, are necessary. Renowned for its essential oil, Cinnamomum burmanii Bark Oil (CbBO) has been utilized extensively in herbal medicine to combat pathogenic bacteria such as Pseudomonas aeruginosa, Candida albicans, Enterobacter spp., and Staphylococcus aureus. This study aims to evaluate CbBO’s antibacterial capabilities using the microdilution method and its antibiofilm properties against K. pneumoniae ATCC 700603 using the MTT test. A CbBO minimum bactericidal concentration (MBC) of 0.25 mg/mL and a minimum inhibitory concentration (MIC) of 0.125 mg/mL were employed for antibacterial activity. The antibiofilm potential was determined by measuring the minimum biofilm eradication concentration (MBEC) at 0.5 mg/mL and the minimum biofilm inhibition concentration (MBIC) at 0.25 mg/mL. In conclusion, CbBO demonstrated antimicrobial and antibiofilm qualities. However,                   a greater concentration of CbBO was required for antibiofilm formation than for antibacterial purposes.

Abstract

The provision of wastewater treatment services is crucial for protecting human health and maintaining clean water availability. This goal is also a key priority in the Sustainable Development Goals (SDGs). However, the wastewater treatment sector in Indonesia is subject to Value-Added Tax (VAT), resulting in higher expenses for wastewater services, including the costs associated with tax collection. Excessive taxation, including VAT, might decrease the availability of domestic wastewater treatment services from the producers' side and restrict consumers' access to these services. Instead, tax policy should provide incentives for domestic wastewater services aiming to promote development. This study examines the adoption of a VAT policy for domestic wastewater treatment services in Indonesia, emphasising its effects on affordability and sustainability in domestic wastewater management and its policy alternatives. This study employs a qualitative approach. Field observations with in-depth interviews and Focus Group Discussions were conducted in several domestic wastewater treatment sites in DKI Jakarta, Medan, and Surakarta. These field observations were conducted to collect data and information about the business processes in the industries and taxation aspects, especially VAT that affects the industries. The results indicate that providing VAT facilities is crucial for advancing the SDGs program. The VAT facilities policy will result in more significant advantages for the government and society than the revenue forgone from the facilities. This study suggests that developing a policy regarding VAT facilities is essential for domestic wastewater treatment systems. The facilities should apply to services provided by local governments or private entities in collaboration with the government. This VAT incentive proposal is simplified due to its compliance with Article 4A paragraph (3) letter (m) of VAT Law No. 42 of 2009, recently amended by Law No. 7 of 2021. While this study has provided insights into the current situation, further studies need to be conducted to investigate VAT facilities' impact on producers and consumers in the wastewater treatment sector, including the multiplier effects of providing VAT incentives.

Abstract

The increasing ownership of motorized vehicles of the motorcycle type in DKI Jakarta, on the one hand, is a potential for vehicle tax revenue that contributes to regional taxes that can be used to improve road infrastructure, on the other hand, it causes problems of congestion and air pollution. The research method used is the literature study method to discuss about analysis concept the Pigouvian tax and earmarking tax in the implementation of motor vehicle tax policies. The results of the study indicate that the implementation of motor vehicle tax reviewed from the Pigouvian tax concept is in the application of progressive tax rates to control the negative external impacts caused by motor vehicles such as congestion, traffic accidents, air pollution, all of which cause social costs that tend to be greater in urban environments, one of which is in DKI Jakarta which has an impact on losses reaching IDR 100 trillion each year from the accumulation of excessive fuel consumption, corrected travel time losses due to congestion, the impact of air pollution caused by burning fuel oil and others. The implementation of motor vehicle tax reviewed from the earmarking tax concept, motor vehicle tax is included in the classification of fixed taxes with reference to a certain percentage of the minimum allocation of 10 percent intended for improving road infrastructure and transportation modes.

Abstract

This study aims to analyze the effectiveness of levy collection at Ragunan Wildlife Park in 2022 and its contribution to the Regional Revenue (PAD) of DKI Jakarta Province. Levy collection is an important source of income for the local government; however, there are several challenges affecting its effectiveness, such as stagnant ticket prices since 2011 and issues with the JakCard payment system. The research employs a descriptive qualitative method, with data collection through observation, interviews, and documentation. Informants were selected using purposive sampling. The findings show that the effectiveness of levy collection at Ragunan Wildlife Park in 2022 was 77%, which is considered fairly effective, although there are still some obstacles. The factors affecting effectiveness include unadjusted levy rates in line with economic developments and technical issues with the JakCard payment system that disrupt the transaction process. Therefore, it is recommended that the local government review levy rates and improve the payment system to enhance the effectiveness of levy collection and its contribution to the PAD of DKI Jakarta Province.

Abstract

The hybrid catenary–battery system offers a promising solution for railways operating in non-electrified sections and during emergencies, ensuring uninterrupted operation, enhanced safety, environmental sustainability, and cost efficiency. This study addresses the challenge of determining an appropriate battery size and introduces a novel rule-based Energy Management Strategy (EMS) with coasting mode to minimize energy consumption while meeting operational requirements. The novelty of this work lies in (i) a straightforward sizing method based on worst-case emergency scenarios and (ii) the integration of coasting-mode operation into a rule-based EMS for hybrid catenary–battery trains. Simulation results show that the proposed approach achieves up to 12.56% energy savings on 3% gradient tracks while fully supplying auxiliary loads, compared with baseline operation that provides only partial coverage. These results demonstrate a practical and scalable framework for designing efficient, reliable, and resilient railway transport systems.

Abstract

This study aims to understand the role of local taxes in supporting public infrastructure development in DKI Jakarta and to reveal factors that influence public awareness, compliance, and expectations regarding tax management. Using a post-positivism paradigm with a qualitative approach, data were collected through document analysis and in-depth interviews with purposively selected communities. Thematic analysis methods were applied to identify key themes in three main dimensions: experience of paying local taxes, experience of using public infrastructure, and expectations regarding local tax policies. The results of the study show that although public awareness of the urgency of taxes for infrastructure development is relatively high, the level of compliance is still not optimal. One digital service such as Samsat Digital Nasional (SIGNAL) has succeeded in increasing the ease of payment, but various obstacles including digital literacy, limited internet infrastructure, and lack of socialization limit its use. On the other hand, the public appreciates major projects such as mass transportation and main roads, but still complains about the inequality of infrastructure in the suburbs and the problem of flooding. Public expectations regarding local tax policies emphasize the importance of transparency, accountability, and public participation in formulating development priorities. These findings emphasize the need for a comprehensive strategy to bridge the gap between awareness of the importance of taxes and factual compliance in paying taxes. Local governments are advised to strengthen the socialization of digital services, prioritize equal distribution of infrastructure, and implement an interactive financial reporting system to build public trust and participation in a sustainable manner. Thus, the capacity of public infrastructure funding through local taxes can continue to be increased, in line with efforts to realize public welfare in the DKI Jakarta Province.

Abstract

Negara maju di dunia umumnya memiliki kepatuhan pajak yang tinggi salah satu faktor yang mendasari kepatuhan pajak adalah tingkat Pendidikan. Indonesia dengan jumlah penduduk yang besar memiliki kepatuhan pajak yang rendah yang ditandai dengan tax ratio yang rendah. Pada 2021 tax ratio Indonesia adalah 10,9 % dan Pendidikan Indonesia menempati peringkat ke 88 dari 167 Negara. Penelitian ini menganalisa pengaruh tingkat pendidikan terhadap moral pajak wajib pajak di Indonesia. Di dalam penelitian ini, pendekatan yang digunakan merupakan pendekatan kualitatif dengan melakukan kajian dari literatur, buku, jurnal, dan dokumen-dokumen lembaga yang terkait dengan topik penelitian ini. Hasil penelitian menunjukan bahwa tingkat pendidikan Indonesia masih rendah yang tercermin dari angka penduduk pekerja dengan tingkat lulusan SD kebawah sebesar 39% dan Angka Anak Tidak Sekolah SMA/sederajat sebanyak 22.52% pada tahun ajaran 2023/2024. Berdasarkan literatur diketahui bahwa Pendidikan dapat memberikan pengetahuan, keterampilan dan nilai-nilai (etika, moral, spiritual dan profesional) yang dapat dikaikan kepada moral pajak individu. Sehingga rendahnya tingkat pendidikan di Indonesia menyebabkan moral pajak rendah karena wajib pajak tidak memiliki pemahaman akan manfaat dari pembayaran pajak bagi Negara.

Abstract

Increasing population growth has resulted in increased vehicle ownership and the need for parking facilities, including in basements. This study aimed to explore the efficacy of palm shell activated carbon panels in reducing CO, NO2, HC, Pb, and noise. The experiment was conducted in a 4 m x 3 m x 2.1 m room using three treatments: without installed activated carbon panels; with 1 cm x 20 cm x 20 cm activated carbon panels; and with 2 cm x 20 cm x 20 cm activated carbon panels. During the measurement, three motorcycles were turned on and kept in idle mode. The concentrations of CO, NO2, HC, ambient Pb, and noise were measured. The results showed that the activated carbon panels were able to reduce CO, NO2, Pb, HC, and noise. The highest performance was obtained for 2-cm thickness of activated carbon panels, with CO, NO2, HC, Pb, and noise decreasing to 824 µg/m3, 8.4 µg/m3, 4.4 µg/m3, 0.2 µg/m3, and 87.44 dB, respectively. Following the adsorption process, the carbon content and pore size of the activated carbon panels had changed from 68.32% to 90.95% and 0.17-3.652 µm to 0.34-5.56 µm respectively for testing with 2-cm thickness panels.
