Abstract

This study investigates the potential utilization of waste cooking oil and used lubricant oil as raw materials for candle production. These waste materials, often regarded as environmental pollutants, contain fats and hydrocarbons that can be converted into value-added products. The manufacturing process involved filtration, heating, and the incorporation of additives such as paraffin wax to enhance quality and stability, followed by molding. The resulting candles demonstrated acceptable physical properties, including melting points and burning times comparable to standard requirements. However, noticeable differences in color and odor were observed when compared to commercial candles. Despite these limitations, the valorization of waste cooking oil and used lubricant oil presents an environmentally friendly and cost-effective alternative, contributing to the development of sustainable products. Further research is recommended to optimize the blending ratios and additive compositions in order to improve the overall performance of the candles

Abstract

Penelitian ini bertujuan untuk mendeskripsikan pemahaman mahasiswa Universitas Negeri Medan (UNIMED) terhadap Wawasan Nusantara serta menilai persepsi mereka mengenai peluang dan ancaman Indonesia dalam menghadapi tantangan geopolitik di era globalisasi. Penelitian menggunakan metode kualitatif deskriptif dengan teknik wawancara semi-terstruktur terhadap tujuh mahasiswa dari berbagai fakultas. Hasil penelitian menunjukkan bahwa sebagian besar mahasiswa memahami Wawasan Nusantara sebagai cara pandang bangsa untuk menjaga persatuan dalam keberagaman. Mahasiswa menilai Indonesia memiliki peluang besar melalui kekayaan sumber daya alam, posisi geografis strategis, keanekaragaman budaya, dan bonus demografi. Namun demikian, globalisasi juga menghadirkan ancaman serius seperti lunturnya identitas bangsa, radikalisme, disintegrasi, serta persaingan ekonomi global. Peran mahasiswa dipandang penting sebagai agen perubahan yang mampu memperkuat nasionalisme, menyaring pengaruh global, serta berkontribusi dalam menjaga keutuhan NKRI. Dengan demikian, Wawasan Nusantara tetap relevan dan strategis dalam membentuk kesadaran geopolitik generasi muda di tengah arus globalisasi.
