Drinking water refilling stations (DWRS) are a growing business, providing affordable drinking water for middle-low urban households in developing countries in the last two decades. However, quality control including water quality and compliance with regulations, is not fulfilled completely by all DWRS. This study aimed to assess water quality and risk of recontamination of DWRS and compliance with administrative-laboratory testing regulations and factors associated with it. A crosssectional study was conducted from March-August 2017 in Bandung City, and 229 of 659 DWRS were selected randomly. The water quality and risk of recontamination from refill gallons and outlet taps were examined using cotton swab and membrane filter methods to identify total coliforms/Escherichia coli. Compliance with administrative-laboratory testing regulations was identified based on the regulations of the Ministry of Health. Results found that water quality was unsuitable in 37.6% of drinking water and 34.1% of raw water. The risk of recontamination was found in 40% of refill gallons and 25.3% of outlet taps. Only 10.5% of DWRS complied with administrative-laboratory requirements. Factors associated with compliance were certified training and good management. An integrated system to manage and control the quality of DWRS is needed to prevent the consumption of nonstandardized drinking water.

Penelitian ini dilaksanakan di Desa Sanggalangit, Kecamatan Gerokgakdengan tujuan: 1) menganalisis kualitas air pada sumber mata air di PuraTaman Desa Sanggalangit sebagai sumber air minum berbasis metodestoret, 2) mendeskripsikan kelayakan air sebagai sumber air minumberbasis metode storet, 3) membandingkan kualitas air pada tahun 2001dan pada tahun 2019. Pengumpulan data menggunakan observasi, metodepencatatan dokumen, dan metode analisis laboratorium. Data yangdiperoleh dianalisis secara deskriptif kualitatif. Hasil penelitianmenunjukan 1) Ditinjau dari sifat fisik dan kimia memenuhi standar bakumutu air mium sedangkan dari sifat biologi mengalami pencemaranringan. 2) Masih layak untuk dikonsumsi tetapi perlu pengolahan terlebihdahulu dan 3) Perbandingan kualitas air di Pura Taman pada tahun 2001dan pada tahun 2019 ditinjau dari sifat fisik masih sama, dari sifat kimiamengalami perubahan dan dari segi biologi mengalami penurunan.

An experimental study on the effect of a cover number of solar distillers with a continuous seawater feeding system was conducted. The seawater feeding in this study was a continuous feeding, which was not utilized yet in the previous studies. Three identical distillers i.e. single caver distiller, double cover distiller, and triple cover distiller were designed and examined. The material tested in this study was seawater taken from Tanjungkarang beach, Mataram, NTB, Indonesia, and converted into distilled water through distillation processes. The overall size of the distillers used was 1136 mm x 936 mm x 574 mm (outer dimension), while the absorber plat size was 0.8 m x 1 m. The experiment was performed in July 2019 from 09.00 to 16.00 local time. The results showed that increasing the number of glass cover decreased the amount of distilled water. The single cover distiller resulted in 949 ml a day, while the double and triple cover distillers resulted in 260 ml and 88 ml a day. The distiller with 3 glass covers was hotter than others so that the seawater vapour could not condense on the glass cover. Therefore, the distiller with a single glass cover was recommended.

Penelitian ini bertujuan untuk mencari faktor penyebab kecacatan serta menetapkan prioritas perbaikan dalam proses pembautan roti mahabah. Dalam pelaksanaan perbaikan yang dilakukan mengacu pada delapan langkah perbaikan dan penggunaan seven tools untuk mempermudah pada setiap langkah yang dilakukan. Adapun dari empat jenis kecacatan yang timbul pada saat proses produksi dilakukan, kecacatan jenis bantatlah yang menjadi fokus perbaikan dengan faktor penyebab kecacatan jenis bantat yang paling dominan yaitu faktor bahan terutama bahan dasar pembuatan roti yaitu terigu. Dengan didapatkannya prioritas perbaikan utama yang harus laksanakan, maka dilakukan analisis yang dilihat dari segi produktivitas parsial bahan baku jenis terigu mana yang baik untuk produksi mahabah. setelah dilakukan perhitungan dari empat jenis terigu yang digunakan, maka dihasilkan jenis terigu yang memiliki produktivitas terbesar yaitu terigu jenis tipe A, yang menghasilkan tingkat keuntungan paling tinggi.
