Abstract

Indonesia hingga saat ini masih menghadapi persoalan dalam mencapai target pembangunan energi karena upaya dalam memaksimalkan pemanfaatan potensi terbarukan belum berjalan sesuai dengan perencanaan. Hal ini disebabkan karena tingginya konsumsi energi fosil belum dapat diimbangi dengan penemuan energi cadangan baru. Padahal Indonesia telah mengalami penurunan produksi energi fosil semenjak 1990-an, status sebagai negara pengimpor juga membuat ketahanan energi minyak nasional berada pada posisi yang termasuk sangat rentan. Kondisi ini akan sangat berpengaruh terhadap implementasi point ke-7 pada Sustainable Development Goals (SDGs), yakni energi bersih dan terjangkau, serta dapat menghambat perwujudan target pada 2030. Disisi lain, kulit udang dan cangkang telur merupakan limbah yang belum dimanfaatkan secara maksimal di masyarakat, padahal keduanya memiliki kandungan yang sangat potensial yakni CaCO3 (kalsium karbonat). Adapun limbah udang yang dihasilkan dari proses pengolahan udang sangat banyak yakni berkisar 30-40% dari berat udang. Berdasarkan data yang kami peroleh, limbah udang mengandung protein kasar sekitar 25-40%, kalsium karbonat 45-50% dan kitin 15-20%. Sedangkan cangkang telur memiliki komposisi mineral, dan tersusun atas kristal CaCO3 (98,41%), MgCO3 (0,84%) dan Ca3(PO4)2 (0,75%). Pada penelitian ini akan dilakukan pereaksian sederhana antara CaCO3 dengan H2O. Di dalam baterai akan terjadi reaksi kimia berupa elektron akan mengalir dari baterai menuju kabel atau kutub negatif ke kutub positif, tempat dimana reaksi kimia tersebut berlangsung. Hasil yang diperoleh dianalisis secara kuantitatif dari tegangan yang ditampilkan dan dilakukan uji konduksi listrik dengan intensitas tertinggi dengan hasil terbaik adalah kombinasi 6 gram cangkang telur dan 2 gram cangkang udang dengan output 1,3 Volt dan High Intensity Light yang dihasilkan. Penelitian ini menunjukkan bahwa limbah cangkang udang dan cangkang telur berpotensi besar untuk menggantikan batere Anoda sebagai energi terbarukan.

Abstract

This study examines the impact of tax information technology services and tax sanctions on property taxpayers' (UN) compliance in Surabaya. Using multiple linear regression, the research finds that tax information technology, service quality, and sanctions all significantly and positively influence tax compliance. Efficient e-filing and e-payment systems enhance reporting accuracy, making compliance more transparent. High-quality services from tax authorities, marked by responsiveness and reliability, increase taxpayer trust, leading to better compliance. Fair and transparent sanctions act as a deterrent, promoting adherence to tax regulations. The study concludes that Surabaya's tax authorities should focus on advancing technology, enhancing service quality, and enforcing consistent sanctions to improve compliance. Recommendations include investing in technology, training tax officers, and strengthening law enforcement. This research offers insights into tax policy in Surabaya and other areas, highlighting the factors that drive local tax compliance and setting the stage for future studies on the relationship between technology, services, and sanctions in enhancing tax compliance.
