Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh lingkungan kerja terhadap pengembangan kompetensi mahasiswa magang di Divisi Akuntansi PT Panca Wira Usaha (PWU) Jatim. Menggunakan pendekatan kualitatif dengan jenis studi kasus, penelitian ini menggali pengalaman mahasiswa dalam mengembangkan kompetensi teknis dan non-teknis selama menjalani magang. Data dikumpulkan melalui wawancara mendalam, observasi partisipatif, dan dokumentasi, kemudian dianalisis menggunakan model interaktif Miles dan Huberman. Hasil penelitian menunjukkan bahwa lingkungan kerja yang kondusif, meliputi aspek fisik, sosial, dan budaya organisasi, memberikan kontribusi nyata dalam meningkatkan keterampilan teknis mahasiswa, seperti penggunaan software akuntansi dan pemahaman prosedur audit. Selain itu, dukungan sosial, komunikasi efektif, serta mentoring dari staf perusahaan turut memperkuat kompetensi non-teknis, seperti kerja sama tim dan etika kerja. Meskipun demikian, mahasiswa menghadapi tantangan seperti adaptasi awal dan keterbatasan akses informasi. Penelitian ini merekomendasikan pentingnya sinergi antara institusi pendidikan dan dunia industri dalam merancang program magang yang relevan, adaptif, dan mendukung pengembangan kompetensi secara menyeluruh

Abstract

The waste diapers, the second largest waste source after plastic, pose environmental challenges due to their slow degradation of 25-50 years. Reprocessing diaper waste, including utilizing Super Absorbent Polymer (SAP), is crucial. SAP's high absorption capacity aids in research for separating crude oil from water, particularly relevant for Indonesian oil wells with aging infrastructure. Emulsions in crude oil, stabilized by natural chemicals, require demulsification to prevent production issues, underscoring the importance of efficient water-oil separation methods. The research experimentally compares oil-in-water emulsion separation using SAP with and without SAP. The study utilizes waste-based ingredients like used diapers, and tests involve centrifuge processes at varying temperatures. SAP's osmotic properties enable high water absorption, impacting demulsification efficiency. This study investigates the impact of temperature on emulsion separation between water and crude oil. Testing at 26°C and 40°C reveals accelerated separation at higher temperatures due to reduced crude oil viscosity. Waste-containing tubes demonstrate better separation, with SAP absorbing water, enhancing separation efficiency. Increasing centrifuge speed and temperature improve oil-water separation, showcasing SAP's effectiveness in waste management processes. Research findings on crude oil-water separation using diaper waste conclude that demulsification is faster at 40°C due to decreased viscosity; with SAP waste, volumes of water are more efficient at 40°C; SAP's hydrophilic nature traps water in the gel network; SAP enhances separation effectiveness compared to non-SAP methods in saline solutions.
