Abstract

Hand sanitizers, handsoaps, and disinfectants (H2D) have become necessities in a new normal during the Covid-19 pandemic. These three items are necessary to use in daily activities to prevent the spread of Covid-19. One of the efforts to successfully adopt a new normal is to educate the youth on preventing the spread of Covid-19. Workshop and education on making simple H2D at SMK Negeri 3 Kotabumi have been held through outreach activities and hands-on practice. The goal of this activity is to increase the students knowledge of SMK Negeri 3 Kotabumi in living a new lifestyle to prevent the spread of Covid-19 in North Lampung Regency. The result of this educational program is an increase in the knowledge of students of SMK Negeri 3 Kotabumi about H2D in terms of composition, making, and use. Besides, through the workshop program, students of SMK Negeri 3 Kotabumi also acquire skills in making simple H2D. Through presentation and direct practice, students of SMK Negeri 3 Kotabumi have been educated to become new lifestyle agents to prevent the spread of Covid-19 in North Lampung Regency.

Abstract

Minyak goreng merupkan salah satu kebutuhan pokok sehari-hari. Hampir semua makanan dan jajanan membutuhkan minyak goreng dalam proses pembuatannya. Salah satu cara agar dapat mengonsumsi minyak goreng adalah penggunaan kembali minyak goreng bekas atau minyak jelantah. Penggunaan berulang dari minyak goreng sangat berbahaya karena selama proses penggorengan terjadi beberapa reaksi seperti oksidasi, hidrolisis dan polimerisasi yang dapat menghasilkan zat karsinogenik. Pada kegiatan pengabdian ini telah dilakukan penyuluhan dan pelatihan penjernihan minyak jelantah menggunakan material penjerap yaitu bleaching earth. Kegiatan terdiri pengumpulan minyak jelantah, penyuluhan bahaya minyak jelantah, praktik penjernihan minyak jelantah, dan analisis hasil penjerapan minyak jelantah. Minyak jelantah yang dikumpulkan berwarna coklat kehitaman sebanyak 2 L. Hasil analisis laboratorium terhadap minyak jelantah yang sudah dijerap dalam kegiatan pelatihan menunjukkan penurunan warna minyak jelantah, bilangan asam dan peroksida. Berdasarkan rangkaian kegiatan yang telah dilakukan, maka penjernihan menggunakan minyak jelantah menggunakan bleaching earth sangat efektif untuk memperbaiki kualitas minyak jelantah.

Abstract

This study successfully synthesized nitrogen-doped carbon quantum dots (N-CQDs) from banana peel waste via a hydrothermal method using urea as the nitrogen source. FTIR and optical characterization confirmed the presence of hydroxyl, carbonyl, and amine functional groups, along with distinct photophysical features, including an absorption peak at 304 nm, excitation at 392 nm, and blue fluorescence emission at 465 nm. Upon Fe(III) exposure, the N-CQDs exhibited selective fluorescence quenching and a measurable hue (H) value shift. A linear relationship was observed between hue and Fe(III) concentration in the 1-5 mM range (R2 = 0.9822). The limit of detection (LOD) and limit of quantification (LOQ) were estimated at 0.948 mM and 2.875 mM, respectively. These findings demonstrate the potential of banana peel-derived N-CQDs as a low-cost, environmentally friendly, and smartphone-compatible fluorescence probe for Fe(III) detection in aqueous environments
