Abstract

Pada penelitian ini dilakukan pengolahan air limbah yang berasal dari industri tekstil melalui proses koagulasi-flokulasi dengan menggunakan koagulan biji kelor dan PAC. Proses pengolahan dilakukan secara bertahap, pengolahan pertama menggunakan biji kelor kemudian dilanjutkan dengan menggunakan PAC. Kandungan asam amino yang terionisasi menjadikan biji kelor berperan sebagai pengikat partikel koloid dalam air limbah. Tujuan penelitian ini untuk mengetahui jumlah dosis optimum biji kelor dan PAC serta waktu pengendapan, kemudian membandingkan bioflokulan biji kelor dalam memperbaiki kualitas fisik kimia air limbah industri tekstil dengan PAC. Dosis serbuk kelor yang digunakan 1.000, 2.000, 3.000, 4.000. 9.000,10.000, 11.000, 12.000 mg/L. Dan digunakan PAC sebagai pembanding dengan dosis : 4.500, 5.000, 5.500, 6.000, 6.500, 4.000, 7.500, 8.500, 9.500 mg/L. Pengaruh dosis koagulan serbuk kelor secara keseluruhan untuk menentukan dosis optimum menunjukkan pada kisaran 2.000 Mg. Sedangkan pengaruh dosis koagulan PAC secara keseluruhan untuk menentukan dosis optimum menunjukkan pada kisaran 6.000 Mg. Berdasarkan hasil perbandingan terhadap KEP-51/MENLH/10/1995 tentang Baku Mutu Limbah Cair Bagi Kegiatan Industri Tekstil, karakteristik akhir air limbah yang telah diolah melalui dua tahap pengolahan tersebut masih melebihi standar baku mutu untuk parameter TDS dan COD. Kualitas hasil pengolahan yang diperoleh lebih tinggi pada pengolahan menggunakan PAC daripada serbuk kelor

Abstract

Water pollution from hospitals comes from waste water; one of the parameters that disturbs aesthetics is ammonia. Ammonia comes from the process of reforming amino acids by aerobic and anaerobic bacteria. One of the ammonia treatment is the chlorination method. The purpose of this study was to reduce the ammonia level of hospital wastewater using the chlorination method. Chlorination is used using hypochlorous acid (HOCl-) or chlorine. The chlorine dose used in the study was 2 mg / l, 4 mg / l, 6 mg / l, 8 mg / l and 10 mg / l. Data analysis using Complete Randomized Design using one way ANOVA Test. The results of research conducted on hospital ammonia wastewater showed that there was an effect of chlorine dose on ammonia levels. Chlorine dose which is quite effective in reducing ammonia levels in the study was 10 mg / l. the effectiveness of this dose can reduce ammonia by 14.08%. The test results obtained there were significant differences in the decrease in ammonia levels in each dose of chlorine with a p value of 0,000 <α = 0,005

Abstract

One way of managing inorganic waste is to make a waste bank. In principle, a waste bank is a place to save waste that has been sorted according to the type of waste. The purpose of this research is to find out information and an in-depth description of the management of waste bank in West Jakarta Administration City which includes operational technical aspects, financing aspects and aspects of community participation. The method used is qualitative method with descriptive research type. Data analysis using qualitative analysis. The results obtained are waste management by making a waste bank is an effective way to reduce waste generation and make the environment clean especially for densely populated areas.

Abstract

One of the programs of the Padang city government in reducing air pollution is with Car FreeDay program which is held every Sunday which is carried out in front of Mesjid Raya Sumatera Barang,Jalan Khatib Sulaiman, Padang City. In this research was intended to determine the effect of the CarFree Day program on ambient air quality with the parameters: NO2 and SO2. The methodology of thisresearch is to carry out direct measurements using an impinger to measure NO2 and SO2.Measurements were carried out for 2 weeks (Non Car Free Day and Car Free Day), then air qualityclassification was carried out using the Air Pollution Standard Index approach (Pendekatan IndeksStandar Pencemraran Udara, ISPU). The results showed that on Car Free Day (Sunday) for parametersof NO2 reduced NO2 values in the air from 43.25 μg/Nm3 to 7.5 μg/Nm3 and for parameters of SO2 onCar Free Day (Sunday) reduced SO2 values from 47,916 μg/Nm3 to 25.5 μg/Nm3 and for theclassification of air quality using Air Pollution Standard Index approach (Pendekatan Indeks StandarPencemraran Udara, ISPU) shows the air quality in front of the Masjid Raya Sumatera Barat, JalanKhatib Sulaiman, Padang City is good.
