Abstract

Sungai Kapuas merupakan salah satu sungai yang melintasi dan menghubungkan beberapa kabupaten yang terdapat di Kalimantan Barat, salah satunya adalah Kabupaten Sanggau. Pemantauan kualitas air dapat dilakukan menggunakan bioindikator, salah satu bioindikator yang bisa digunakan adalah rheofitoplankton. Tujuan penelitian ini untuk mengetahui keanekaragaman rheofitoplankton dan kualitas air di Sungai Kapuas di Kabupaten Sanggau. Pengambilan sampel dilakukan pada 4 stasiun dengan 3 kali ulangan pada masing-masing titik pengambilan. Pengambilan sampel dilakukan pada bulan Nopember dan Desember 2011. Rheofitoplankton yang diperoleh sebanyak 37 genera yang terdiri dari divisi Chrysophyta sebanyak 14 genera, Chlorophyta 15 genera dan Cyanophyta 8 genera. Kelimpahan tertinggi terdapat pada lokasi satu (1092,61 Ind/l) dengan kelimpahan genera tertinggi yaitu Desmidium dan Spirogyra. Kelimpahan terendah terjadi pada lokasi dua (801,7 Ind/l) dengan kelimpahan genera tertinggi yaitu Spirogyra dan Rhizosolenia. Indeks keanekaragaman rheofitoplankton (H) berkisar antara 2,2920-2,8470, indeks dominansi Simpson (D) berkisar antara 0,0710-0,1670, indeks kemerataan Sorensen (E) berkisar antara 0,753-0,916. Berdasarkan analisis keanekaragaman rheofitoplankton, Sungai Kapuas di Kabupaten Sanggau sudah tercemar ringan, namun kondisi fisika-kimia air masih mampu mendukung kehidupan rheofitoplankton.

Abstract

Arbuscular vesicular mycorhizae (AVM) is a fungus that has mutualistic symbiosis with plant roots. Arbuscular vesicular mycorhizae (AVM) has ability to boost plant growth but information regarding this types of fungi at Mecca onion (Eleutherine americana) is still unknown. This study aims to determine the type of arbuscular vesicular mycorhizae (AVM) and level of infection at rooting of Mecca onion (E. americana). This research was conducted in Laboratory of Microbiology, Faculty of Mathematics and Natural Sciences, University of Tanjungpura from July 2014 to September 2014. The analysis of soil samplewas conducted at the Laboratory of Chemistry and Soil Fertility, Faculty of Agriculture, University of Tanjungpura. Isolation of soil samples employed two techniques, wet filter chamber and centrifugation. The study found that as many as 277 arbuscular vesicular mycorhizae (AVM) spores derived from genus Glomus(9 types), Acaulospora (3 types) and Paraglomus (1 type). The observation of root preparation indicated that structure of arbuscular vesicular mycorhizae (AVM) contained spores and hyphae with the percentage of root infection was 12,5%, and it is classified into low category.

The data were analyzed using both qualitative and quantitative analysis. The qualitative analysis was conducted to find out the types of plants, parts that were used and the processing methods. The quantitative analysis used the Frequency of Citation (FIC) and the Informant Agreement Ratio (IAR). The research found 28 species belonging to the 22 families. The most widely used family was theZingiberaceae which consisted of 4 types of plants. The most widely used part of the plant was the root. The most common ways of processing the plants were by boiling and grindingthem first. The category of plant utilization was divided into 6,i.e.to treat cancer, excretory system, digestive system, respiratory system, reproductive system, and circulatory system. The highest citation frequency in this research was 92.87%;the highest score of the Informant Agreement Ratio (IAR) was in the category of the excretory system disease, i.e. 0.952.

Abstract

Tofu industrial wastewater containing high protein causes highly suspended solids (TSS) and dissolved solids (TDS). Moringa oleifera and Tamarindus indica seed powder can be used as a coagulant to reduce TSS and TDS. This study aims to determine best dose and the effectiveness of the combination Moringa and Tamarind seeds in improving the quality tofu liquid waste. The research was conducted in Pebruary to April 2013. Value TSS, TDS and total bacteria before treatment at high 1232 mg/l, 8432 mg/l and 2,7107 CFU/ml. The best treatment was at the dose K2:A1 (Moringa 133,3 mg and Tamarind 66,7 mg) with the final value TSS 151 mg/l, while the final value TDS 2794 mg/l. Best treatment for the total bacteria was at the dose K1:A2 (Moringa 66,7 mg and Tamarind 133,3 mg) with the final value 3,1106 CFU/ml. Once the tofu liquid waste is treated, the mean value of dissolved oxygen was 3,09 to 3,67 ppm and the degree of acidity was 4,67 to 5,00.
