Abstract

Water naturally contains various minerals, one of them is fluoride ion. Fluoride in water with suitable amounts give good benefits for health, but give the opposite result in excessive amounts. The purpose of this study was to determine the levels of fluoride contained in bottled drinking water and some well water samples in Banda Aceh. The fluoride amount in bottled drinking water and the well water was analyzed using UV-Vis Spectrophotometry at 570 nm wavelength. The measurement results show that the six samples have fluoride ion levels below 1 mg/L. This proves that the water is suitable for consumption and use because it meets the quality standards of SNI 01-3533-2006 (maximum 1 mg/L for bottled drinking water) and the Health Minister Regulation of Republic Indonesia Number 32 Year 2017 (maximum 1,5mg/L in water for hygiene and sanitation purposes).

Abstract

Telah dilakukan penelitian dalam menganalisis kadar nitrit pada air bersih dengan metode Spektrofotometri UV-VIS.Dari penelitian ini diperoleh hasil analisis kadar nitrit yang diperoleh dari sampel air PDAM berkisar antara 0,0020 - 0,0102 mg/L , air baku sebesar 0,0030 - 0,0114 mg/L dan air sumur sebesar 0,0041 – 0,0159 mg/L.Kadar nitrit yang diuji pada sampel air PDAM, air baku dan air sumur memenuhi standar mutu Permenkes Nomor 32 Tahun 2017 yaitu kurang dari 1 mg/L.

Abstract

Telah dilakukan penelitian dengan tujuan untuk mengetahui pengaruh penambahan tawas Al2(SO4)3 dan soda ash Na2CO3 terhadap turbiditas dan pH air baku pada instalasi pengolahan air bersih (IPA). Dari penelitian ini diperoleh bahwasanya tawas Al2(SO4)3 dan soda ash Na2CO3 dapat membantu proses koagulasi-flokulasi sebagai penyangga pH. Pengaruh penambahan tawas dan soda ash pada air baku yaitu dapat menurunkan kadar turbiditas dan mempertahankan pH pada air baku (yang telah diolah). Sehingga menghasilakan air bersih yang sesuai standar baku mutu menurut Permenkes No. 32 Tahun 2017.

Abstract

Essential oil is a type of oil that is produced from various parts of the plant, is a thick liquid at room temperature, and evaporates easily, giving it a distinctive aroma. One of the essential oils is used as an antibacterial compound. This study aims to measure the variation in the deposition of various types of essential oils as an inhibitor of the growth of Staphylococcus aureus bacteria. This research method is a Literature Review by examining the use of various concentrations of various types of essential oils to inhibit the growth of Staphylococcus aureus bacteria. The best inhibition of growth of Staphylococcus aureus bacteria was obtained in the essential oil of basil leaves at a concentration of 4% with inhibition of 40.35 mm. Meanwhile, the lowest inhibition of growth of the Staphylococcus aureus bacteria for black fungus isolates was obtained at a concentration of 0.5% with an average inhibition zone of 1.16 mm.

Abstract

Daging olahan merupakan salah satu jenis makanan cepat saji yang banyak dikonsumsi oleh masyarakat. Untuk meningkatkan kualitas daging olahan, seringkali dilakukan penambahan Bahan Tambahan Pangan (BTP) seperti pengawet. Nitrit merupakan pengawet yang umum digunakan pada daging olahan dengan tujuan untuk menghambat pertumbuhan bakteri Clostridium botulinum sehingga memperpanjang umur simpan produk. Metode penelitian yang digunakan yaitu Literature Review dengan pengumpulan dan skrining data yang memiliki kriteria inklusi dan eksklusi. Hasil yang diperoleh yaitu berbagai informasi mengenai tahapan analisis kandungan nitrit menggunakan metode spektrofotometri dengan pereaksi Griess sehingga menghasilkan warna merah keunguan dan dilakukan pengukuran absorbansi pada panjang gelombang maksimum dengan rentang 420-573 nm.
