The Effect of Adding Limnocharis Powder (Limnocharis Flava) on the Catfish (Pangasius Hypopthalmus) Abon Quality

The study aims to determine the influence of the addition of powder limnocharis to the quality of sherdded catfish. The method used is experimenting with Design Random Complete (DRC) non factorial, as the treatment is powder limnocharis which consists of four of which are: A0 without the addition of powder limnocharis, of the A1 with the addition of powder limnocharis 20 grams, A2 with the addition of powder limnocharis 40 grams and A3 by the addition of powder limnocharis 60 grams. Parameters that is organoleptic and chemical. The result showed that the best of the quality of sherdded is the addition of powder limnocharis 20 grams. The organoleptic with the criteria like chocolate green; the smells of sherdded catfish and spices is strong; the typical sherdded catfish; the texture of tiny fibers and soft. The chemical with a value of the water content of 4.48 %, protein content 29.40 % and levels of fiber 2.75 %

Karakterisitik Fisiko-Kimia Dan Sensori Bakso Ikan Gabus (Channa Striata) Dengan Penambahan Genjer (Limnocharis Flava)

The purposes of this research were investigated the physicochemical and sensory characteristics of snakehead fish ball with yellow velvetleaf addition. The research was conducted on January until March 2016. The research method was used randomized block design (RBD). The treatments were 0%, 5%, 10%, and 15% of yellow velvetleaf addition. The parameters of this research was chemical analysis such as water content, ash content, protein content, lipid content, carbohydrate content, and fiber; physical analysis were elasticity; colour and sensoric analysis (texture, taste, colour and aroma). The results showed that treatment gave significant effect on ash content, water content, ash content, protein content, and fiber content; lightness and sensoric analysis (taste and colour), but there were no effect to lipid content, carbohydrate content and elasticity, chrome and hue. The concentration of water, ash, protein, and fiber were 63.32%-69.27%, 1.21%-6.44%, 14.69%-20.61%, 0.93%-5.65% respectively. The lightness of this fish ball were54.23%-6676%. Color sensory analysis of fish ball were 3.28-3.86 and taste were 3.17-3.36. The best treatments were A2 (10% yellow velvetleaf addition)

Penyerapan Ion Logam Kadmium Dan Tembaga Oleh Genjer (Limnocharis Flava)

Telah dilakukan penelitian tentang penyerapan ion logam kadmium dan tembaga olehgenjer (limnocharis flava) dengan metode dinamis. Dari hasil penelitian didapatkan kondisioptimum penyerapan pada pH 5, ukuran partikel 180 μm, dan suhu pemanasan 90o C.Kapasitas penyerapan untuk Cd(II) adalah 17,71 mg ion logam/g sorben, sedangkan untukCu(II) adalah 17,45 mg ion logam/ g sorben. Ion logam yang telah diserap dielusi denganHNO3 dan EDTA dengan recovery 63,44-100%. Penyerapan ion logam kadmium dantembaga pada kondisi optimum yang diaplikasikan pada air limbah laboratorium kimiamempunyai kapasitas penyerapan masing-masing adalah 0,030 dan 0.013 mg ion logam/ gsorben

Remedition of Organic Pollutan's in the Wastewater of Rubber by Biosand Filter Media and Water Plants (Echinodorus Palaefoliu and Limmnocharis Flava) for Media of Fish Life

The research was conducted from February-Apryl 2014 at PT. RiauCrumb Rubber Factory of Pekanbaru, in the road Kelurahan Meranti PandakKecamatan Rumbai. It's was aims to understand the effectiveness of biosand filtermedia and phytoremediation concept in remediation organic pollutans content inliquid wastewater of rubber for media of fish life. Sampling of BOD5 and CODwere taken in 5 place with interval every 10 days during 2 months for 4 times andanalyzed in departement public of laboratory. Liquid wastewater of rubber usingof 8 reactor units. Each other 2 reactor units to biosand filter media of control andother combined biosand filter with water plants have can reducing organicpollutans. BOD5 of primary Concentration about 387-465,3 mg/l and the end24,3-6,29 mg/l with effectivenesses 89,07-98,73%. While that COD about 710-846,6 mg/l and the end 44,3-45,8 mg/l with effectivenesses 80,39-96,47%.Altough to other parameter such as temperature about 29-310C, pH 6 and DOabout 3,5-3,83 mg/l can support for media of fish life. Percentage of survival ratefor Esomus sp and Pangasius pangasius 100% altough Oreochromis nilothicus93,75-100%. It's reached standart quality of KEP-51/MENLH/10/1995

Eksplorasi Tanaman Fitoremediator Aluminium (Al) Yang Ditumbuhkan Pada Limbah IPA Pdam Tirta Khatulistiwa Kota Pontianak

Pembuangan limbah Instalasi Pengolahan Air Minum yang dilakukan secara terus-menerus ke badan air tanpa adanya upaya pengolahan terlebih dahulu dapat memicu menurunnya kualitas badan air. Limbah proses instalasi pengolahan air minum ini berpotensi sebagai pencemar karena banyaknya kandungan Aluminium (Al) dari limbah yang dibuang setiap harinya. Penelitian kajian pemanfaatan tumbuhan air sebagai pengendali limbah cair, dikenal dengan proses fitoremediasi. Penelitian ini bertujuan untuk mengetahui tingkat efektivitas dari tanaman penyerap logam (Eceng gondok, Genjer dan Melati air) melalui proses fitoremediasi dalam menurunkan kandungan Al pada limbah instalasi pengolahan air minum PDAM Tirta Khatulistiwa Pontianak. Pengambilan sampel limbah dilakukan langsung pada pipa buangan IPAM PDAM Kota Pontianak, kemudian dilakukan pengukuran kandungan logam Al tahap awal (sebelum proses fitoremediasi). Selanjutnya dilakukan proses penanaman tanaman penyerap logam selama 70 hari dan kemudian dilakukan pengukuran kandungan Al tahap akhir untuk mengetahui efektivitas tanaman dalam menyerap logam. Hasil penelitian menunjukkan bahwa konsentrasi Al pada limbah dari instalasi pengolahan air minum Kota Pontianak melebihi batas yaitu sebesar 314,74 mg/l. Tingkat efektivitas yang dihasilkan oleh masing-masing tanaman penyerap logam yang digunakan dalam penelitian ini yaitu 96,46% untuk tanaman melati air, 80,21% untuk tanaman eceng gondok dan 94,65% untuk tanaman genjer. Sehingga dapat disimpulkan bahwa tanaman melati air merupakan tanaman terbaik dalam menyerap logam Al pada limbah yang dihasilkan oleh instalasi pengolahan air minum PDAM Tirta Khatulistiwa Kota Pontianak
