Abstract

Levels of Fluorine (F) greater than 1.5 mg/l can cause stomach ailments, bone loss and brown enamel, fluorosis, liver damage, kidney damage and bone fragility (osteoporosis). This study aimed to perform the processing of fluorine with the coagulation, flocculation, and adsorption systems, so as to minimize the levels of fluoride in the water. The methods of coagulation and flocculation made use of lime (5%) and alum (5%), with rapid stirring variation 5, 10, 15 minutes and slow stirring 3 minutes at a pH adjusted to 8 and looping treatments (replication) of each 6 times for every 500 ml of water processed. Dug well water in Bantal Village, District of Asembagus, Situbondo, East Java, has a value of pH = 6.6 with a high fluorine concentration = 1.93 mg/l. Fluorine processing technology with the coagulation and flocculation systems  for lime and alum is strongly influenced by the dose of pH and alum. Precipitation using alum achieves maximum results at pH = 8.1 with a dose of 5% lime and alum dose of approximately 5 ml of 5% in the ratio 1 : 4 and the deposition time = 60 minutes. In these conditions about 1.63 mg/l (83.93%) fluorine content of dug well water decreases from initial value of 1.93 mg fluoride / l to 0:31 mg/l. There are varying levels of fluorine (F) dug well water samples before and after coagulation and flocculation processes of lime and alum. Rapid stirring = 5 minutes can reduce the average fluorine content of 1.39 mg/l (72.53%), rapid stirring = 10 minutes can reduce the average fluorine content of 1.57 mg/l (80.82%) and rapid stirring = 15 minutes can reduce the average fluorine content of 1.63 mg/l (83.93%). Further research needs to be done by varying the addition of alum to reduce the dose volume of fluorine up to the limit allowed by the Minister Regulation. 416/Menkes/Per/IX/1990 of these Terms and monitoring of water quality = 1.5 mg/l.

Abstract

The aim of this research is to know closely the effects of the extract of pineapple peels cayenne in killing the bacteria Eschericia coli in the disinfection process of fresh water. The variations of dosages in the research were as follows: treatment 1 : 1000 ml of sampling water intervened by 100 ml of extract of pineapple peels cayenne; treatment 2 : 1000 ml of sampling water intervened by 250 ml of extract of pineapple peels cayenne; treatment 3 : 1000 ml of sampling water intervened by 500 ml of extract of pineapple peels cayenne. The control was sampling water without any intervene of the extract. Each treatment was observed to see the effects of the extract in killing the bacteria Eschericia coli. The result of the literary study, field test, and laboratory test showed the characteristics of extract of pineapple peels cayenne pH : 3,86, the temperature : 29,4 ºC, the humidity : 74,8%, the total sum of acid : 1,71%, organic acid : 0,585, protein : 0,42% and enzyme bromelin : 0.050 – 0.075 unit/ml. The close estimation indicated the total sum of bacteria Eschericia coli in the treatment 1 : 104,6 per 100 ml; in the treatment 2 : 47 per 100 m; in the treatment 3 : 17 per  100 ml, and in the control group : > 2400 per 100 ml. In the treatments 2 and 3 the quality of bacteriology of sampling water already fulfilled the standard of quality as stated in The Regulation of The Health Ministry of Indonesia (Permenkes RI) no. 416/Menkes/Per/IX/1990 about The Standard of Quality of fresh water and drinking water that requires the maximum contents of Eschericia coli = 50 per 100 ml on non-plumbing water. The statistical result of Kruskal Walls Test and t-test proved that there were some effects and different effects among the variations of dosages of the pineapple peels extract cayenne in killing the bacteria Eschericia coli.

Abstract

Salah satu masalah kesehatan di Indonesia adalah tingginya prevalensi penyakit cacinganpada semua kelompok umur. Anak usia sekolah dasar adalah merupakan golongan yang palingsering terkena infeksi cacingan. Tujuan penelitian ini adalah untuk mengetahui PHBS dan hygiene perorangan siswa diSekolah Dasar Negeri 2 Ngiliran di Kecamatan Panekan, Magetan. Jenis penelitian ini adalahdeskriptif  melalui pendekatan deskriptif survey. Sampel penelitian adalah 64 orang siswa.Pengumpulan data dilakukan dengan wawancara untuk mengetahui karakteristik siswa dan perilakusiswa, observasi terhadap lingkungan sekolah dan sanitasi lingkungan sekolah. Hasil penelitian menunjukkan pengetahuan, sikap, kebiasaan siswa menggunakan alaskaki, kebersihan kuku dan makanan jajanan (hygiene perorangan) kurang. Setelah dilakukan analisis dan pembahasan disimpulkan bahwa pengetahuan siswatentang PHBS kurang, kurangnya hygiene perorangan siswa, kurangnya kebiasaan menggunakanalas kaki, hygiene makanan jajanan yang kurang baik dan kebersihan kuku siswa yang menyebabkan penyakit cacingan. Perlunya penelitian lebih mendalam dan luas dengan variabel-variabel lain yang belum tergali seperti screening menggunakan rectal swab untuk mengetahuiangka infeksi cacingan.
