Abstract

The depletion of fossil fuel reserves has led to a global energy crisis, with increasing demand for alternative energy sources. Diesel fuel shortages, especially in countries like Indonesia, have driven the exploration of biodiesel as a sustainable alternative. This study aims to convert waste cooking oil (WCO) into biodiesel, with the addition of a cetane number improver (CNI) to enhance its performance in diesel engines. The biodiesel was produced through methanolysis, and 2-Ethylhexyl Nitrate (EHN) was added to improve combustion and reduce engine knocking. The results show that the produced biodiesel had a density of 856 Kg/m³ for B0, 872.7 Kg/m³ for B0 with CNI, and 872.1 Kg/m³ for B50CN. Viscosity values were 2.32 cSt for B0, 5.645 cSt for B50, and 4.722 cSt for B50CN. The cetane index was 49.2 for B50 and B50CN, while B0 had a value of 48. The emissions measured included CO levels of 194 mg/Nm³ for B0, 254 mg/Nm³ for B50, and 280 mg/Nm³ for B50CN. NOx emissions were 852 mg/Nm³ for B0, 755 mg/Nm³ for B50, and 825 mg/Nm³ for B50CN. Oxygen content was 15.9% for B0, 14.9% for B50, and 16.2% for B50CN. The findings indicate that adding EHN to WCO biodiesel improves fuel properties but increases emissions of CO and NOx. Overall, WCO-based biodiesel with EHN is a viable alternative fuel that balances performance improvements with environmental considerations.

Abstract

Yayasan Darus Solihin yang terletak di Jl. Soekarno Hatta Km. 17, Kecamatan Balikpapan Utara, Kota Balikpapan. Saat ini, Yayasan Darush Sholihin masih berfokus pada penyelenggaraan pendidikan nonformal untuk siswa pada tingkat PAUD dan SD, namun adapun permasalahan yang ada di Yayasan Darus Sholihin yaitu pada pembuatan media baca yang kurang aktif, kurangnya edukasi pada media baca, kurangnya sosialisasi terhadap masyarakat sekitar. Selain itu, belum adanya fasilitas penunjang untuk tempat membaca dan belajar. Metode pelaksanaan yang digunakan yaitu Community-Based Participatory Research (CBPR) yang dilakukan pendekatan dengan masyarakat dan pemanfaatan teknologi melalui pengembangan kartu Augmented Reality (AR) sebagai media baca. Hasil kegiatan menunjukkan peningkatan antusiasme anak dalam membaca serta keterlibatan masyarakat dalam mendukung program. Hasil kegiatan dilakukan dengan cara wawancara dan observasi yang menunjukkan adanya peningkatan antusiasme anak-anak terhadap kegiatan membaca serta meningkatnya partisipasi masyarakat dalam mendukung program literasi. Penggunaan media AR terbukti mampu menarik minat baca anak secara menyenangkan dan edukatif melalui visualisasi tiga dimensi dan interaksi langsung. Secara keseluruhan, pendekatan kolaboratif berbasis teknologi ini berkontribusi positif terhadap penguatan budaya literasi anak dan dapat menjadi model pengembangan program literasi digital di lembaga pendidikan nonformal di masa depan.
