The purpose of this study was to determine the effect of giving coleus amboinicus, L leaf’s extract, on the percentage of carcass, liver, heart and abdominal fat and the level of coleus amboinicus,L extract which is appropriate in broiler feed. This research was conducted in labor and broiler enclosures of the Payakumbuh State Agricultural Polytechnic, from January to May 2018. The material was DOC, commercial food 311, corn, bran, soybean meal, fish meal and minerals, and the equipment used was cages and equipment. The design used is RAL with 6 treatments and 4 replications. The results obtained that the addition of coleus amboinicus, L extract, L did not affect significantly (P> 0.05) on the percentage of carcass and liver, while the administration of coleus amboinicus, L leaf’s extract significantly affected (P <0.05) on the percentage of heart and abdominal fat broiler. Giving a dry of coleus amboinicus leaf’s, L, 4 g / kg ration can reduce broiler abdominal fat.
Penelitian ini untuk mengetahui pengaruh pemberian infusa daun bangun-bangun terhadap performa ayam pedaging. Metode yang digunakan Rancangan Acak Lengkap (RAK) dengan 5 (lima) perlakuan dan 4 (empat) ulangan, metode yang digunakan Rancangan Acak Lengkap RAL). Setiap unit percobaan ditempati oleh lima ekor ayam. Penelitian ini menggunakan lima taraf perlakuan infusa daun bangun-bangun (Coleus amboinicus, Lour) dalam air minum dan empat ulangan. Perlakuan A1 = 0% infusa daun bangun-bangun, perlakuan A2 = 0,5% infusa daun bangun-bangun, A3 = 1% infusa daun bangun-bangun, A4 = 1,5% infusa daun bangun-bangun, dan A5 = 2% infusa daun bangun-bangun. Pemberian infusa daun bangun-bangun dalam air minum tidak signifikan (P> 0,05) pada pertambahan bobot badan, konsumsi, dan konversi pakan. Disimpulkan dari penelitian ini: pemberian infusa daun bangun-bangun dapat ditoleransi hingga 2% dalam hal berat badan, konsumsi ransum dan konversi ransum. Penambahan bobot tertinggi diperoleh pada pemberian 2% infusa dalam air minum.
Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ekstrak daun miana dalam air minum dengan level yang berbeda. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL)dengan perlakuan adalah level ekstrak miana yaitu 0 % (kontrol) (A), 0,025%(B), 0,075% (C) dan 0,125% (D), dan diulang sebanyak 5 kali. Peubah yang diamati adalah pertambahan bobot badan, konsumsi ransum, konversi ransum dan persentase karkas.. Data yang diperoleh dianalisis sesuai rancangan yang digunakan dan pengaruh yang nyata dilanjutkan dengan uji Duncan. Hasil analisis ragam menunjukkan bahwa pemberian 0,075 % dan 0,125% ekstrak miana nyata (P<0,05) meningkatkan bobot badan, sedangkan pemberian ekstrak miana 0,125% nyata (P<0,05) menurunkan konversi ransum . Pemberian ekstrak miana dalam air minum tidak berpengaruh nyata (P>0,05) terhadap konsumsi ransum dan persentase karkas broiler. Disimpulkan bahwa pemberian 0,075% ekstrak miana memberikan konversi ransum dan pertambahan bobot badan broiler yang terbaik Kata kunci: ekstrak daun miana, konsumsi ransum, konversi ransum dan persentase karkas
Science and technology program for community activities (IbM) of organic fertilizer / compost on plant wake was held in the herd Permato mudo villages and natural ox Silaing porch in the village below, the Western District of Padang Panjang, Municipality of Leopold. This activity aims to increase the milk production of dairy cows through the use of leaves wake up in the candy lick. The benefits of this activity is to assist farmers in improving milk production of dairy cows per day, so it can increase milk production which increased revenue. To achieve the goal of community service mentioned above, it has conducted lectures, live demonstrations on planting crops wake (Coleus amboinicus, Lour) are produced using organic fertilizers. Area is used as a demonstration plot is 2500m2 with planting distance is 30 x 40 cm, with NPK fertilizer 550 kg / ha, organic fertilizers 10 tons / ha and 12 tons of organic fertilizer / ha. Evaluation showed that the high activity of plant organic fertilizers 12 tons / ha higher than NPK fertilizer with organic fertilizer 10 tons / ha.Of these service activities can be concluded that the use of compost 12 kg / ha can increase height and crop production wake than that of compost 10 tons / ha with NPK fertilizer.
The decrease of soil fertility and fewer soil microorganisms will lower crop production, particularly rice, thus threatening the national food security program. This study is (a) to isolate and identify the bacteria in the endophytic and rhizosphere of rice plants (b) to study the bacteria from the endophytic and rhizosphere of rice plants which potentially stimulate plant growth. The experiment was carried out at the Laboratory of Food Crop Cultivation at Payakumbuh State Agriculture Polytechnic, Limapuluh Kota Regency, West Sumatra for four months. The sampling method was carried out by random sampling at rice planting in the Payakumbuh State Agriculture Polytechnic Experimental Field. Endophytic bacteria were taken from the root tissue of rice plants, and rhizosphere bacteria were taken from a layer of soil around rice roots. Isolation of bacteria was carried out by using the pour plate and scratchplate methods. Four bacteria were identified using the 16S rRNA sequencing method. The identification results showed that in the rice root tissue found the bacteria Chromobacterium rhizoryzae and Brevibacillus brevis. In the rice rhizosphere, Bacillus pseudomycoides and Bacillus thuringiensis are found. Bacteria are dominated by the Bacillus genera which can stimulate plant growth.
