However, in connection with the Covid-19 Pandemic Virus, it was banned temporally by the government, even through a circular number; P-004/DJ.III/ Hk.007/04/2020, issued by the Ministry of Religion. By literature research known that Prohibition and prevention aimed at gathering people in large groups, both in terms of ibadah and muamalat is an attempt to break the chain of the spread of the COVID-19 virus pandemic. Therefore, further studies on prevention, especially prevention of the implementation of the walimat al-‘ursy during the COVID-19 virus pandemic will be examined through the analysis of sad adz-dzari'ah.

In this study total 20 fruit juice samples of five different types were repeatedly subjected to bacteriological and mycological screening for three months. Isolates were identified and confirmed using cultural and biochemical characteristics. Current study showed high bacterial and fungal loads consisting of specific pathogens such as coliform and Staphylococcus spp., fecal coliform and other pathogens are totally absent. The presence of Staphylococcus aureus portends health risk to consumers as some species produce potent toxins associated with food borne illnesses. And high bacterial count indicated unhygienic conditions of the processing area, and that good manufacturing practices during processing are not maintained properly. Recommendations are required to reduce the microbiological contamination and promote quality assurance of the products. Stamfo...

Konsentrasi sisa klorin ini dapat berkurang yang diakibatkan oleh laju kehilangan klorin yang dipengaruhi oleh perilaku hidraulika jaringan distribusi. Studi ini bertujuan melakukan simulasi hidraulika sisa klorin dengan mengambil studi kasus sistem distribusi air minum pada perumahan PT. Pusri Palembang. Pembangunan model sistem distribusi dilakukan menggunakan perangkat lunak EPANET 2.0, yang kemudian disimulasikan berdasarkan extended period simulation (EPS) selama 24 jam. Hasil simulasi hidraulika menunjukkan bahwa kapasitas jaringan distribusi masih sangat memadai ditinjau dari segi penyediaan tekanan sisa. Walaupun demikian, kecepatan aliran hampir di seluruh jaringan distribusi sangat lambat sehingga tidak memenuhi kriteria desain yang layak. Hal ini menyebabkan waktu tinggal air menjadi sangat lama, sehingga konsentrasi sisa klorin yang memenuhi syarat tidak dapat terpenuhi. Perbaikan hidraulika dilakukan dengan melakukan pembesaran dan pengecilan diameter pipa dengan tujuan mengoptimalkan parameter kecepatan aliran dan kehilangan tekanan. Simulasi sisa klorin pada jaringan distribusi setelah perbaikan hidraulika menunjukkan konsentrasi sisa klorin hampir di setiap node telah memenuhi syarat. Walaupun demikian, diperlukan penambahan booster klorin untuk menjaga konsentrasi sisa klorin agar tidak kurang dari 0,2 mg/L. Kata Kunci: Sisa Klorin, Laju Kehilangan Klorin, Hidraulika Pipa, EPANET 2.0
