Abstract

This study aims to determine the response and appropriate concentration of liquid organic fertilizer from banana peel waste on the growth and yield of sweet corn (Zea mays saccharata Sturt L.). The research method was a field experiment using a Randomized Block Design with various concentrations of liquid organic fertilizer from Kepok banana peel waste. The treatments are P0 = 0 ml/litre of water, P1 = 50 ml/litre of water, P2 = 100 ml/litre of water, P3 = 150 ml/litre of water, P4 = 200 ml/litre of water, and P5 = 250 ml/litre of water. Each treatment was repeated four times. The data obtained in this study were analyzed using Analysis of Variance at the 5% error level and followed by the Duncan Multiple Range Test (DMRT).  The results showed that the application of various concentrations of organic liquid fertilizer made from Kepok banana peel has a significant effect (p<0.05) on plant height, leaf count, stem diameter, cob length without husk, cob diameter without husk, and cob weight without husk. It can be concluded that the treatment with the concentration of Kepok banana peel organic liquid fertilizer at P2 (100 ml/litre of water) yielded the best results for plant height, leaf count, stem diameter, cob length without husk, cob diameter without husk, and cob weight without husk.

Abstract

Income Tax Article 23 (PPh 23) is one of the important instruments in the Indonesian taxation system that  targets deductions on income from capital, services, or gifts and awards. This study aims to review the  implementation, calculation, recording, and reporting of PPh 23 based on studies that have been conducted in  various companies such as PT Semara Perkasa Lestari, PT Store Sent e-Logistik Indonesia, Perum Bulog, PT Grin Kar Indonesia, and PT Perkebunan Nusantara Enam. The method used is a literature study of relevant journals, tax regulations such as Government Regulation No. 36 of 2008, and the practice of implementing e-Bupot Unification. The results of this study indicate significant challenges in terms of compliance, technical  mastery of calculations, and adaptation to electronic reporting systems. This study recommends increasing  socialization and training for business actors and optimizing the e-Bupot system. This study is expected to be a reference for academics, tax practitioners, and taxpayers in understanding and implementing PPh Article 23  more appropriately and efficiently.

Hasil penelitian menunjukkan bahwa Kepercayaan berpengaruh positif dan signifikan terhadap kepuasan pelanggan dengan koefisien determinasi sebesar 53,2%. Kualitas layanan berpengaruh positif dan signifikan terhadap kepuasan pelanggan dengan koefisien determinasi sebesar 67,2%. Secara simultan, kepercayaan dan kualitas layanan berpengaruh signifikan terhadap kepuasan pelanggan dengan koefisien determinasi sebesar 70,1%. Berdasarkan temuan tersebut, disarankan agar J&T Express meningkatkan transparansi informasi, kecepatan respons layanan pelanggan, serta pengembangan fitur aplikasi untuk memperkuat kepercayaan dan kualitas layanan, sehingga dapat meningkatkan kepuasan pelanggan.
