Abstract

Pyrotechnic materials are a category of materials that are often used in various applications, including military activities, lighting, signaling, and combat effects. In this study, an experiment was conducted to create a light pyrotechnic material using gunpowder, which is a mixture of potassium nitrate, sulfur, and activated carbon. The manufacturing process involved the activation of carbon from fly ash bottom ash (FABA) waste and the composition of different pyrotechnic materials. The experiment involved testing pyrotechnic compositions with varying ratios of KNO3 : carbon : sulfur. The results showed that the composition with a ratio of 15 : 7.5 : 7.5 produced the highest light intensity, reaching 104 lux, and provided optimal visual effects. In addition, the relative proportions of oxidizer, carbon and sulfur affected the type of pyrotechnic effect produced. Pyrotechnic light generation from gunpowder could be considered successful, and the best composition for spectacular visual effects was a ratio of 15 : 7.5 : 7.5. However, sufficient caution and knowledge were required in the use of pyrotechnic materials to ensure safety and compliance with applicable regulations.

Abstract

Kesadaran bela negara sudah sepatutnya disadari secara luas dan khususnya diterapkan oleh generasi muda Indonesia saat ini. Gagasan tersebut hendaknya disampaikan secara strategis kepada siswa-siswa SMA untuk mempersiapkan sumber daya manusia berkualitas yang mendukung pertahanan negara, khususnya dalam mengantisipasi ancaman Bahan Kimia, Biologi, Radiologi, Nuklir, dan Bahan Peledak (CBRN-E). Namun informasi mengenai pemahaman CBRN-E pada tingkat siswa SMA di Indonesia masih terbatas. Pengabdian masyarakat ini bertujuan untuk memberikan profil khusus pemahaman siswa SMA setempat terhadap ancaman CBRN-E sebagai wawasan program selanjutnya dalam mengantisipasi ancaman CBRN-E. Selain melakukan sosialisasi kepada siswa SMA di salah satu SMA tertentu di Kabupaten Bogor, kami menganalisis secara singkat pemahaman awal mereka terhadap isu-isu terkait pertahanan dan topik terkait kimia melalui pre-test kuesioner yang dirancang. Hasil studi pendahuluan ini menunjukkan bahwa pengetahuan mereka tentang ancaman CBRN-E harus diperkuat. Menariknya, sebagian besar peserta mempunyai persepsi positif mengenai preferensi karir mereka untuk mendukung sektor pertahanan negara, misalnya minat mereka untuk berkontribusi di bidang kimia untuk memperkuat pertahanan negara. Temuan ini menyiratkan mendorong pemangku kepentingan pendidikan untuk berkolaborasi secara strategis dengan lembaga pertahanan negara untuk mengintegrasikan materi pembelajaran terkait CBRN-E ke dalam kurikulum yang ada.

Abstract

In terms of hygiene and sanitation, ensuring the availability of qualified water for those purposes remains challenging to perform under certain conditions. Accordingly, efforts to provide simple water processing technology are ongoing and innovatively developed. This study displayed an innovative approach to producing coagulants for water processing by utilizing metal salts obtained synthetically from used beverage cans and iron plates through the electrolysis principle and characterized using Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and Scanning Electron Microscopy - The Energy Dispersive X-ray (SEM-EDX), subsequently. After mixing with calcium hypochlorite and adding to water sample, subsequently, the coagulant showed the ability to reduce the turbidity level and several categories of impurities, i.e., nitrate, nitrite, dissolved Manganese, Cr6+ ion, and microbial levels. Future research and development in formulating coagulants derived from digested beverage cans and iron plate wastes hold significant potential to advance sustainable and efficient water treatment technologies, ensuring improved hygienic quality of fresh river water while contributing to waste valorization and environmental protection.
