Abstract

The aim of this study is to determine, the comparison of absorption by aquatic plants Hydrilla verticillata and Water hyacinth (Eichhomia crassipes) of malathion insecticide residues in water and comparison of malathion concentration in tissues of fish fed with of contaminated water plants (Water hyacinth) with tissues of fish, which was not fed contaminated water plant. The effect of heating the contaminated fish tissue, on its level in tissues of rats that consume it. For the first experiment (aquarium filled with 3 litre of water + H. verticillata 100 gr + Water hyacinth 100 gr + 20 uci 14C-labeled malathion); for the second experiment (the first aquarium filled with 3 litre of water + 30 tails of goldfish + 20 uci 14C-labeled malathion; second aquarium filled with 3 litre of water + Water hyacinth 100 gr + 30 tail of goldfist + 20 uci 14C –labeled malathion. For the third experiment (most of contaminated fish tissue in the second experiment was dried at room temperature and then given to 30 mice and partly heated and then given to another 30 mice). Malathion levels were then analyzed by using a liquid scintillation counter LSC-753 (Aloka). The results of all treatments were compared using the Student t-test. It can be concluded, H. verticillata was more efficient compared to the enceng gondok in absorbing the insecticide malathion residues in water; malathion concentration in the tissues of fish fed Water hyacinth was higher than those of fish not fed Water hyacinth; contaminated fish tissue residues of malathion, although be heated, can not be lowered significantly, levels in the tissue.

Abstract

ABSTRAK Penelitian ini bertujuan untuk mencari Program Cekaman Luruh Bulu yang cocok dan menguntungkan dengan kondisi lingkungan dan kondisi peternak di Indonesia. Penelitian ini menggunakan180 ekor ayam tipe medium (Dekalb Warren), umur 84 minggu. Percobaan yang berfaktor 2×2×2, menggunakan rancangan acak lengkap (RAL) dengan lima kali ulangan dan setiap ulangan terdiri atas 4 ekor ayam. Faktor pertama yaitu pemberian minum dan puasa minum selang sehari. Faktor kedua ialah jangka waktu puasa makan 10 hari dan puasa makan 5 hari. Faktor ketiga ialah jumlah makanan yang diberikan pada masa pemulihan yaitu pakan dengan jumlah 50%, dan 25% dari komsumsi normal. Jadi ada 9 jenis perlakuan program cekaman luruh bulu yang dicobakan. Data hasil penelitian dianalisis sidik ragam (ANOVA), dan dlakukan uji perbandingan orthogonal. Hasil penelitian menunjukkan, bahwa perlakuan B (puasa makan 10 hari pertama, tidak puasa minum, hari ke 11 sampai dengan ke 30, diberi pakan 25% dari normal, dapat meningkatkan rataan produksi telur ayam tua menjadi 68,20%, memperbaiki konversi ransum, dan nilai Haugh Unit dengan sangat nyata. Penelitian ini juga memperlihatkan bahwa metode Cekaman Luruh Bulu yang dipakai dalam penelitian ini, kalau diterapkan pada ayam tua akan mendapatkan keuntungan Rp 2.500.000,- per 1000 ekor ayam; sebaliknya kalau ayam tua itu dibiarkan saja bertelur terus tanpa perlakuan, peternak akan merugi Rp 467.000,- per 1000 ekor ayam. STRESS METHODS FOR MOLTING SUITABLE FOR CONDITIONS IN INDONESIA ABSTRACT The objective of the research is to find out the appropriate and beneficial forced molting program that suitable with the environment and the condition of the farmer in Indonesia. The research used 180 medium type chickens, strain Dekalb Warren, aged 84 weeks old. The research applied 2×2×2 factors and used complete randomized design in (CRD) 5 times replications with 4 chickens for each repeat. The first factor was water supplying and without water supply. The second factor was the duration of no feeding for 10 and 5 days. The third factor was the amount of feed given during recovery period, that was 50% and 25% of the normal consumption. So, the total of the treatment of forced molting program applied were 9 treatments. Data obtained were analysed using analysis of variance (ANOVA), orthogonal comparison test. The result obtained showed that the treatment B (without feeding for the first 10 days, having water supply, day 11 to 30 were feed 25% of normal consumption) could be increasing the average of egg production of old chicken to 68.20%, improving feed convertion, egg quality: Haugh Unit value, yolk percentage, significantly and no differences were obsesrved among treatments versus control for egg weighth, albumen percentage, eggshell thickness. The result was also showed that the Forced Molting Stress Method used in this experiment, would be giving profit of Rp 2,500,000;- per 1,000 chickens if implemented; in the contrary, if the old chickens are allow to keep laying egg without treatment, the farmer would get deficit of Rp 467,000;- per 1,000 chickens.
