Abstract

The objective of this study was to analyze the influence of Environmental Concern, Innovation, Social Media Effectiveness, Brand Image, and Green Product Awareness on Purchase Intention through Trust, moderated by Brand Equity, among electric car consumers in East Java. This study used causality, using primary and secondary data sources. The sample population was 195 electric car consumers in East Java. The analytical technique chosen to analyse the data and test the hypotheses in this study was the Structural Equation Model. The results of the study prove that Environmental Concern has a positive but insignificant effect and Innovation has a negative but insignificant effect on Consumer Trust; while Social Media Effectiveness, Brand Image and Green Product Awareness have a positive and significant effect on Consumer Trust; Environmental Concern has a negative but insignificant effect and Innovation has a positive but insignificant effect on Consumer Purchase Intention; while Social Media Effectiveness has a negative but significant effect and Brand Image has a positive but significant effect on Consumer Purchase Intention; except that Green Product Awareness has a positive but insignificant effect on Purchase Intention; Trust has a positive but significant effect on Consumer Purchase Intention; and Trust has a negative but insignificant effect on Purchase Intention moderated by Consumer Brand Equity.

Abstract

Objective: This study aims to (1) examine the influence of service quality, patient relationship management, and service fairness on patient satisfaction and loyalty, and (2) test whether patient satisfaction mediates the influence of service quality, patient relationship management, and service fairness on patient loyalty. Method: A quantitative approach was employed with a survey conducted on 320 respondents, consisting of inpatients in several hospitals in DKI Jakarta, and the data were analyzed using linear regression analysis and mediation tests. Result: The findings of this study are: (1) the quality of service has no effect on patient satisfaction and loyalty; (2) patient relationship management has no effect on patient satisfaction but has a positive effect on patient loyalty; (3) service fairness has a positive effect on patient satisfaction and loyalty; (4) patient satisfaction has no effect on patient loyalty; (5) patient satisfaction is not an intervening variable between service quality and patient relationship management to patient loyalty; and (6) patient satisfaction is an intervening variable between service fairness and patient loyalty. Novelty: The results show that service justice has a great influence on both patient satisfaction and loyalty, proving that the variable of service justice in which there are indicators of retributive justice is a proven novelty, highlighting the importance of leaders in formulating policies related to fairness in service and ensuring the implementation of fair services by all hospital employees to increase satisfaction and ultimately foster patient loyalty.

Abstract

The stock price is a factor that investors must consider in investing. The stock price is an indicator of the successful management of the company. An increase in share price will reflect an increase in shareholder wealth as an investor. There is a phenomenon in banking stock prices in Indonesia from 2020-2021, where share prices have decreased yearly. This study aimed to investigate the effect of company performance on stock prices by using interest policy as a moderating variable. The method used in this research is panel data regression. The results show that performance positively affects stock prices, and interest policy moderates the relationship between performance and stock prices.

Abstract

High-Voltage (HV) Testing on the 150‑kV High-Voltage Underground Cable (SKTT) system is essential to verify insulation integrity following faults or relocations associated with National Strategic Projects. Conventional testing methods using a Mobile Test Unit (MTU) often face cost and logistical constraints. This study evaluates the effectiveness of a reverse energization method utilizing a 150/20‑kV Power Transformer as an alternative test source, using the 150‑kV SKTT Taman Rasuna–Durentiga Circuit #2 as the case study. ETAP simulations indicate that this method can deliver a 34.7‑A test current on the 150‑kV side through an injection of 260.4 A from the 20‑kV side at a test voltage of 152.8 kV. Operational safety is ensured through cascading protection coordination between the Line Current Differential relay (<100 ms) and the 20‑kV incoming OCR (100 ms). From an economic standpoint, the reverse‑transformer method requires only IDR 26.43 million, significantly lower than the MTU cost of IDR 358.51 million, resulting in 92.63% cost savings. The findings demonstrate that the reverse power‑transformer method is a reliable, safe, and highly cost‑efficient testing solution for PLN UPT Cawang operations.

Abstract

Penelitian ini bertujuan mengevaluasi kelayakan finansial Pembangkit Listrik Tenaga Air (PLTA) run-of-river Watunohu melalui integrasi analisis hidrologi berbasis Flow Duration Curve (FDC), evaluasi indikatif optimasi debit desain, serta potensi pendapatan kredit karbon berdasarkan mekanisme Article 6 Perjanjian Paris. Pendekatan kuantitatif evaluatif digunakan dengan menginterpretasikan data hidrologi dan FDC dari studi kelayakan terdahulu, melakukan simulasi beberapa alternatif debit desain secara indikatif untuk menilai produksi energi tahunan dan capacity factor, serta mengevaluasi kelayakan finansial menggunakan indikator net present value (NPV), internal rate of return (IRR), profitability index (PI), dan payback period (PP). Debit desain final, parameter teknis, serta komponen CAPEX dan OPEX tetap mengacu pada studi kelayakan sebelumnya untuk menjaga konsistensi desain. Analisis dilakukan pada dua skenario, yaitu skenario dasar dan skenario dengan integrasi pendapatan karbon. Hasil penelitian menunjukkan bahwa proyek PLTA Watunohu memenuhi kriteria kelayakan finansial pada skenario dasar dengan NPV sebesar Rp247,97 miliar, IRR 8,19%, dan PP 10,53 tahun. Integrasi mekanisme Article 6 meningkatkan kinerja finansial proyek dengan menaikkan NPV menjadi Rp261,79 miliar dan IRR menjadi 8,27%. Analisis sensitivitas menunjukkan bahwa biaya investasi dan nilai tukar merupakan faktor yang paling berpengaruh terhadap kelayakan finansial proyek, sedangkan variasi capacity factor memberikan dampak yang relatif terbatas.
