Abstract

Liquid waste from sasirangan industrial activities has a high enough Chemical Oxygen Demand pollutant power. If it is directly discharged into water bodies, it can damage the environment and harm health. One of the first processes needs to be done by using activated corn cobs (Zea mays). This study aimed to analyze the ability of corn cobs charcoal to reduce levels of Chemical Oxygen Demand and increase the pH of sasirangan waste so that the results of this study can be an alternative to natural-based sasirangan waste treatment. This type of research is a pure experiment with a research design in One Group Pretest Posttest Design. The research material used was sasirangan industrial waste in Manarap Village, Kertak Hanyar District, Banjar Regency, South Kalimantan, Indonesia. Chemical Oxygen Demand levels were determined by the closed reflux titrimetric method. The results showed that the addition of the highest dose of activated corncob charcoal (50 g) reduced the largest turbidity by 35 percent, increased the pH by 72 percent, and reduced the color intensity by 33 percent. The conclusion is that the addition of corncob-activated charcoal at a dose of 30gr, 40gr, 50gr can reduce levels of Chemical Oxygen Demand, respectively, namely 24 percent, 35 percent, and 33 percent. An increase in pH was found at the same dose of 46 percent, 62 percent, and 72 percent, respectively. There is an effect of increasing the mass of activated charcoal from corn cobs on the Chemical Oxygen Demand levels in the sasirangan industrial waste with a significance value of 0.007. It is suggested to use corn cobs-activated charcoal for the pretreatment stage of sasirangan industrial waste treatment.

Abstract

Anemia defisiensi besi dan thalassemia memiliki gambaran morfologi darah hipokrom yang sama, oleh karena itu perlu dibedakan dengan dilakukannya sebuah pemeriksaan. Tujuan menggunakan menzter indeks untuk membedakan dan mendeteksi subyek yang memerlukan tindak lanjut yang tepat dan untuk mengurangi biaya yang tidak perlu. Diagnosis banding antara anemia defisiensi besi dan thalassemia didasarkan pada hasil HbA2 elektroforesis, kadar status besi berupa kadar feritin serum, Serum Iron (SI), Total Iron Binding Capacity (TIBC) dan Saturasi Transferin (ST). Tujuan penelitian ini adalah untuk mengetahui perbedaan nilai indeks Mentzer, HbA2 dan Status besi antara anemia defisiensi besi dan thalassemia. Manfaat penelitian ini memberikan informasi jika pemeriksaan indeks mentzer dapat digunakan sebagai skrining awal untuk membedakan Anemia Defisiensi Besi dan Thalasemi. Jenis penelitian ini survei analitik dengan rancangan studi komparatif. Sampel diambil secara Total sampling dengan jumlah 20 pasien anak Anemia defisiensi Besi dan 20 pasien anak Thalasemia di RSUD Ulin Banjarmasin pada bulan Juli-Agustus 2022. Hasil analisis statistik menggunakan uji Independent Samples Test menunjukkan nilai signifikansi untuk menzter indeks 0,000, Total iron binding capacity 0,002 dan HbA2 0,000. Dengan menggunakan analisis uji Mann-Whitney menunjukkan nilai signifikansi pada serum iron sebesar 0,000, saturasi transferin 0,000 dan ferritin 0,000. Maka H1 diterima karena nilai sig < 0,05. Kesimpulannya penelitian ini terdapat perbedaan bermakna antara nilai indeks mentzer, HbA2, feritin, serum iron, total iron binding capacity, saturasi transferin antara pasien anemia defisiensi besi dan thalassemia pada pasien anak di RSUD Ulin Banjarmasin
