PENGARUH KITOSAN TERHADAP SITOLOGI GINJAL TIKUS PUTIH (Rattus sp.) JANTAN YANG DIPAPARI PLUMBUM ASETAT
No full textThe study aimed to determine the effect of chitosan on the kidney of rats (Rattus sp.) exposed to lead acetate. Thirty five male animals weighing 250g were divided into 7 groups: K group as a control (without treatment), P1 received Pb (40 mg/kg bw as lead acetate), while P2, P3, and P4, all received Pb (40 mg/kg bw) and chitosan (0,5%, 0,75%, and 1% respectively). P5 group received only chitosan (1%) and P6 group received acetic acid. After 7 weeks of treatment, the animals were sacrificed and the kidneys were isolated. Kidney damage was observed with microscopis. Result showed, treatment of Pb (40 mg/kg bw) in male rats caused demage microscopis. Chitosan able to decrease kidney damage resulted from Pb treatment. In conclusion, chotosan has the ability to reduce residue of Pb as well as microstructure damage of rat kidney exposed to Pb

P5 group received only chitosan (1%) and P6 group received acetic acid. After 7 weeks of treatment, the animals were sacrificed and the kidneys were isolated. Kidney damage was observed macro and microscopically, and the residue of Pb in kidney tissue was evaluated using Atomic Absorption Spectrophotography. Result showed, treatment of Pb (40 mg/kg bw) in male rats caused kidney damage macro and microscopically. Chitosan able to decrease kidney damage resulted from Pb treatment. Residue of Pb in the kidney of rat exposed to Pb acetate was decreased after chitosan treatment. In conclusion, chitosan has the ability to reduce residue of Pb as well as macro- and microstructure damage of rat kidney exposed to Pb. The effectiveness of chitosan as a chelating agent for Pb in the organs, especially in the kidneys is important for further investigated.The study aimed to determine the effect of chitosan on the kidney of rats (Rattus sp.) exposed to lead acetate.

Penelitian ini menggunakan 35 tikus tikus putih jantan (Rattus sp.) dengan berat badan 250g. Sampel di bagi menjadi 7 kelompok, K (kontrol) diberikan Mb dan aquadest, (P1) diberikan Pb, P2, P3, P4 diberikan Pb dan kitosan dengan konsentrasi berbeda yaitu (0,5%; 0,75%; dan 1%). P5 diberikan kitosan 1% dan P6 diberikan asam asetat. Organ ginjal tikus, diambil pada minggu ketujuh setelah perlakuan untuk melihat derajat penurunan kerusakan sekaligus penurunan residu Pb setelah pemberian kitosan. Data yang di peroleh dari penelitian diolah dengan menggunakan program SPSS 18, untuk data makrosruktur dan mikrostruktur maka diuji menggunakan Kruskal Wallis dan Mann Whitney. Sedangkan data residu Pb dalam ginjal tikus dilakukan dengan uji parametrik dan nonparametrik (uji Kruskal Wallis dan Mann Whitney). Dari hasil analisa di peroleh; 1. Pemberian Pb sebesar 40mg/KgBB/hari pada tikus putih (Rattus sp.) terbukti dapat merusak makrostruktur dan mikrostruktur ginjal, 2. Kemampuan kitosan sebagai pengkelat Pb, terbukti dapat mengurangi derajat kerusakan makrostruktur dan mikrostruktur ginjal tikus putih (Rattus sp.), 3. Pemberian kitosan pada tikus putih (Rattus sp.) yang dipapari Pb menunjukkan adanya penurunan residu Pb. Kesimpulan, kitosan memiliki kemampuan menurunkan derajat kerusakan marostruktur, mikrostruktur dan residu Pb dalam ginjal. Keefektifan kitosan sebagai pengkelat Pb dalam organ tubuh terutama ginjal masih perlu diteliti lebih lanjut.77 HalamanTesis Magiste
Analisa AB-Mix Dan Air Cucian Beras Pada Pertumbuhan Tanaman Selada (Lactuca Sativa, L.) Dengan Wick System Hidroponik
No full textAB mix nutrition consists of two different packages, the elements contained in it are macro (N, P, K, Mg, Ca, S) and micro (Fe, Zn, Mo, Cu, Mn, Bo, Cl, Si, Na, Co). Rice washing water contains nitrogen, phosphorus, carbohydrates, sulfur, magnesium, potassium, vitamin B1 and iron. The results showed that the treatment dose of rice washing water had a significant effect on plant height, number of leaves and root weight. The higher the dose of rice washing water, 30 ml/water, the higher the plant growth will be. The results of research on the interaction of AB mix treatment with rice washing water had no significant effect on plant height, leaf color and root weight in lettuce plants.

No full textPenelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk AB mix cair dan pupuk organik cair terhadap pertumbuhan dan produksi tanaman sawi pakcoy. Penelitian ini dilaksanakan pekarangan rumah Jalan Ayahanda, Gang Garpu No 10a. Penelitian ini dilaksanakan pada bulan Juni–Juli 2022. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan dua faktor perlakuan, yaitu pupuk AB mix cair dan pupuk organik cair. Faktor pertama adalah pupuk AB mix cair, yaitu A1=550 ppm/plot, A2=750 ppm/plot, dan A3=1000ppm/plot. Faktor kedua adalah pupuk organik cair, yaitu B1=80 ml/plot, B2=140 ml/plot, dan B3=200 ml/plot. Parameter yang diamati adalah jumlah daun, lebar daun, berat tanaman per plot, dan produksi per tanaman. Hasil penelitian ini menunjukkan bahwa perlakuan pupuk AB mix cair berpengaruh nyata terhadap jumlah daun di 20 dan 30 HST namun tidak berpengaruh nyara pada jumlah daun 10 HST, lebar daun, berat tanaman per plot, dan produksi per tanaman. Pada perlakuan pupuk organik cair berpengaruh nyata pada jumlah daun 30 HST namun tidak berpengaruh nyata pada jumlah daun 10 dan 20 HST, lebar daun, berat tanaman per plot, dan produksi per tanaman. Interaksi perlakuan pupuk AB Mix cair dan pupuk organik cair berpengaruh tidak nyata terhadap semua parameter amatan.
