Abstract

Study of the effect of several concentrations of plant growth regulator (Sa-kawa) on seed germination and seedling growth of lerak (Sapindus rarak D.C ) on compost media was carried out in the Plant and Animal Germplasm Garden of Cibinong. The objective of this study was to know optimum concentration of plant growth regulator on growth of lerak This study was arranged by using randomized complete design (RCD) with 3 (three) replications. The treatments of concentrations variation of plant growth regulator i.e.?é?á 0 (control), 1, 2 and 3 ml/l were used. Each treatment consists of 5 samples (individuals).. The results showed that?é?á the good concentration to the growth parameter?é?á such as growth percentage, plant height, total leaves, root length and total root were 2 ml of Sakawa in?é?á 1ml/l (one liter of water).

Abstract

This study aims to investigate: the influence of the number of participants crop (soy-bean), the influence of Rhizobium sp dosage, interactions influence the number of participants crop (soybean) and Rhizobium sp dose to the total wet weight and num-ber of tiller Pennisetum purpureum, the planting of grass-soybean intercropping Rhi-zobium sp inoculation. The research method uses randomized full factorial (factorial RCBD) with 2 factors and 3 replications. Parameters to be measured is the total wet weight and number of tiller Pennisetum purpureum. The data obtained were analyzed by analysis of vari-ance, followed by Duncan multiple range test and multiple linear regression ana-lysis. The results showed that treatment of soybean plants participant, dose Rhizobium sp, and participant interaction with defoliation of soybean Rhizobium doses of 1 and 2 did not significantly affect the total wet weight and number of tiller Pennisetum pur-pureum. However, in the second defoliation, Rhizobium dose significantly influence the total wet weight of Pennisetum purpureum. The conclusion is, cropping the grass-soybean intercropping with inoculation of Rhi-zobium sp can not be used to increase the total wet weight and number of grass tiller.Key words: Pennisetum purpureum, wet weight, tiller, Rhizobium sp, soybeans.

BROILER PRODUCTION OPTIMIZATION OF PERCENTAGE OF HERBAL SUPPLEMENTATION THROUGH AND CARCASS BLOOD TRIGLYCERIDE LEVELS ?é?á ABSTRACT People appreciate meat products free antibiotics or organic food products. Prevention of chemical substance in the broiler chicken meat can be done by mixing feed ingredients with herbal, with the addition of herbal powders like turmeric, ginger, and?é?á basil. The purpose of this study was to examine the influence of herbal supplementation on carcass percentage and blood triglyceride levels?é?á broiler. his research uses three kinds of herbs that is turmeric (P1), Basil (P2), and Ginger (P3). There are four treatment including control (P4), with four replicates. The design of this research is complete a draft random. The research results were analyzed with Anova test followed by Duncan test. The results showed there was a very real influence due to the addition of herbs to the percentage of carcass?é?á (P<0,01). The levels of triglyceride of blood a broiler indicating the result is no different real (P>0,05). Key words: Carcass, Blood Triglycerudes, Herbal Supplementation, Broiler. ?é?á ABSTRAK Masyarakat semakin memperhatikan produk daging yang bebas antibiotik atau produk makanan organik. Pencegahan penumpukan zat kimia dalam daging ayam broiler tersebut dapat dilakukan dengan pencampuran pakan dengan bahan-bahan herbal atau alami, yaitu dengan penambahan serbuk herbal seperti kunyit, jahe, dan kemangi. Tujuan penelitian ini adalah mengkaji pengaruh suplementasi herbal terhadap persentase karkas dan kadar trigliserida darah ayam broiler. Penelitian ini menggunakan tiga macam herbal yaitu kunyit (P1), kemangi (P2), dan jahe (P3). Ada empat perlakuan termasuk kontrol (P4), dengan empat ulangan.?é?á Rancangan penelitian ini adalah rancangan acak lengkap. Hasil penelitian dianalisis dengan Anova, dilanjutkan dengan uji Duncan. Hasil penelitian menunjukkan ada pengaruh yang sangat nyata pemberian herbal terhadap persentase karkas (p<0,01). Paramater kadar trigliserida darah menunjukkan hasil tidak berbeda nyata (P>0,05).
