Abstract

Pemadaman yang dilakukan untuk pekerjaan pemeliharaan,menyebabkan kerugian bagi konsumen serta PLN. Kerugian yang dialami adalah diskontinuitas pelayangan penyaluran energi listrik dan kwh yang diproduksikan oleh PLN tidak dapat tersalurkan, maka dari itu perlu dilakukan pemeliharaan dengan teknik Hot Line Maitenance (HLM). Keandalan dari indeks SAIDI (System Average Interruption Duration Indeks) SAIFI (System Average Interruption Frequency Indeks). Di PT PLN (Persero) UP3 Medan dapat menyelamatkan kWh dan rupiah terselamatkan dari bulan Juli hingga Desember 2022. Nilai rata-rata Saidi dari bulan Juli hingga Desember 2022 yaitu 38,614 menit/pelanggan. Nilai rata-rata Saifi dari bulan Juli hingga Desember 2022 yaitu 0,420 kali/pelanggan. Perlunya pengembangan sehingga dapat meningkatkan jumlah kWh yang terselamatkan dan menekan angka Saidi, Saifi sekecil mungkin. Keandalan sistem pada jaringan tegangan menengah tetap terjaga dan tidak dirugikan akibat pemadaman listrik.

Abstract

The consumption of sugar-sweetened packaged beverages among adolescents continues to increase along with changes in lifestyle and dietary patterns. Limited knowledge regarding artificial sweeteners, recommended intake limits, and the potential health risks of excessive consumption may contribute to unhealthy beverage choices. This community service program aimed to improve students' knowledge of artificial sweeteners in packaged beverages through health education at SMP IT Citra Ummat, Tidore Islands City. The program involved 67 seventh- and eighth-grade students and was implemented through interactive lectures, discussions, question-and-answer sessions, supported by PowerPoint presentations, educational banners, and leaflets. Knowledge was assessed using pre-test and post-test questionnaires, and the data were analyzed using the Wilcoxon Signed Rank Test. The results showed that 33 students (49.3%) experienced increased knowledge scores, 23 students (34.3%) showed no change, and 11 students (16.4%) had decreased scores. Statistical analysis demonstrated a significant difference between pre-test and post-test scores (Z = -3.500; p = 0.000), indicating that the educational intervention effectively improved students' knowledge regarding artificial sweeteners in packaged beverages. The program also enhanced students' awareness of the importance of reading nutrition facts and ingredient labels before purchasing packaged beverages. Health education can therefore serve as an effective promotive strategy to improve food safety literacy among adolescents.
