Abstract

Sumber utama operasional pemerintah daerah adalah pendapatan asli daerah (PAD), dimana pajak kendaraan bermotor (PKB) memberikan kontribusi yang cukup signifikan. Namun demikian, masih banyak tunggakan pajak kendaraan bermotor yang menghambat optimalisasi penerimaan daerah. Untuk mengatasi hal ini, UPT Pengelolaan Pendapatan Daerah (PPD) Jember menerapkan publikasi surat administrasi perpajakan sebagai upaya menagih tunggakan PKB, yaitu Surat Pendataan Subjek dan Objek Pajak Kendaraan Bermotor (SPSO), Nota Perhitungan Pajak Kendaraan Bermotor (NPP), dan Nota Tagihan Pajak Kendaraan Bermotor (NTP). Pengabdian ini bertujuan untuk mengetahui optimalisasi PAD melalui publikasi Surat Administrasi Perpajakan dalam mengurangi tunggakan PKB. Metode yang digunakan meliputi observasi, wawancara, dan diskusi dengan pihak UPT PPD Jember. Hasil pengabdiannya menunjukkan bahwa penerbitan surat administrasi perpajakan mampu meningkatkan kesadaran wajib pajak untuk membayar kewajibannya. Realisasi penerimaan PKB pada tahun 2023 mencapai 105,10% dari target, sedangkan pada tahun 2024 meningkat menjadi 114,08%. Selain itu, PAD UPT PPD Jember tahun 2024 mengalami peningkatan sebesar 6,95% dibandingkan tahun 2023.

Abstract

This study evaluated the effectiveness of coagulants and flocculants in improving clarifier water quality, with a focus on pH, iron (Fe) concentration, and turbidity levels. In accordance with Indonesia’s Ministry of Health Regulation No. 32/2017 on environmental health standards for water, clarifier water samples were analyzed before and after treatment. The results show that the treated water complied with the specified standards, with pH levels ranging from 6.5 to 8.5, Fe concentrations below 1 mg/L, and turbidity under 25 NTU. The application of aluminum sulfate as a coagulant and polymer as a flocculant effectively reduced Fe concentrations and turbidity while adjusting the pH to acceptable levels. These findings confirm the critical role of coagulation and flocculation in industrial water treatment processes and demonstrate their potential for enhancing water quality in clarifier systems.
