Abstract

This experiment aims to determine the population of phosphate solubilizing bacteria (PSB) in non-rhizosphere and rhizosphere plants on dry land in the rainy season. The experiment was conducted for 3 months including sampling at three strata system farm of Faculty of Animal Husbandry at Bukit Jimbaran; analysis of soil at Laboratory of Animal Production Technology and Microbiology Faculty of Animal Husbandry and at Soil Science Laboratory, Faculty of Agriculture, Udayana University. This experiment follows an additive linear model with the assumption that the difference only caused by the different types of plants while other factors are uniformly homogeneous. Sampling was done on four rhizosfere including; non-rhizosphere (NR), Gliricidia sepium rhizosphere (RG), Leucaena leucochepala rhizosphere (RL), and Sesbania grandiflora rhizosphere (RT) with four replications. The variables observed in this experiment including: Total PlateCount (TPC), Total phosphate solubilizing bacteria (PSB), P (phosphorus) element, and water content. The result showed that TPC soil in the range of 0,57×108-5,6×108cfu/g, showed no significant different to all treatment. Total phosphate solubilizing bacteria (PSB) in range of 0,35×107 - 2,88×107cfu/g showed no significant different to all treatments. P (phosphorus) elements, in tretment NR same withtreatment RT are range of 10,27ppm significant different with RG and RL. Water content ranged from 9,25 - 9,84 % With the result is highest in treatment RG was no significant higher than RT and markedly higher than the NR and RL. Based on the experiment it could be concluded that the population of phosphate solubilizing bacteria (PSB) in non-rhizosphere tend to is lower compared with RG, RL, and RT on dry land in the rainy season. The content of P (phosphorus) element in non-rhizosphere is same with RT but lower than RG and RL. Water content in non-rhizosphere same with RL but lower than RG and RT. Keywords: phosphate solubilizing bacteria, non rhizosphere, rhizosphere

Abstract

This research has purpose to study the influence of giving cellulotic bacteria culture through drinking water as probiotic source to carcass physical composition of Balinese duck aged 8 weeks. Ducks that are used in this research were 54 Balinese ducks aged 1 day. Design used in this research is the Complete Random Design (CRD) with three treatments and six times of repetition. The three treatments are the ducks given drinking water without supplementation of cellulotic bacteria culture as control (A); drinking water with 0,20% cellulotic bacteria culture (B); and drinking water with 0,40% cellulotic bacteria culture (C). Variables that are observed are the percentage of carcass meat, percentage of carcass bone, percentage of carcass fat, and protein consumption. Research result shows that the giving of cellulotic bacteria culture as probiotic source at level of 0,20%-0,40% through drinking water shows the percentage of carcass meat at treatment (B) and (C) is significant (P0,05) which is higher than control (A), the percentage of subcutan fat including skin at treatment (B) and (C) shows significant result (P0,05) lower than control (A). From this research it can be concluded that the influence of giving cellulotic bacteria culture of buffalo rumen isolate as probiotic source through drinking water given at level of 0,20%-0,40% can increase the percentage of carcass meat and reducing the percentage of carcass fat of Balinese ducks aged 8 weeks.

Abstract

Penelitian bertujuan untuk mengetahui pertumbuhan dan hasil tanaman kelor (Moringa oleifera Lam.) yang ditanam pada berbagai jenis tanah dan dipupuk dengan beberapa dosis pupuk fosfat. Penelitian dilaksanakan selama 3 bulan di Rumah Kaca, Desa Sading, Kecamatan Mengwi, Kabupaten Badung, Bali. Rancangan percobaan yang digunakan adalah rancangan acak lengkap (RAL) pola tersarang. Faktor pertama adalah jenis tanah, terdiri atas: tanah mediteran, tanah latosol, dan tanah regosol dan faktor kedua adalah dosis pupuk fosfat (TSP), terdiri atas: P0 = kontrol, P50 = 50 kg/ha, dan P100 = 100 kg/ha. Variabel yang diamati yaitu variabel pertumbuhan, hasil dan karakteristik tumbuh tanaman. Hasil penelitian menunjukkan bahwa pertumbuhan tanaman kelor (Moringa oleifera Lam.) yang ditanam pada berbagai jenis tanah secara statistik menunjukkan hasil yang berbeda nyata, namun berbeda tidak nyata terhadap panjang akar. Pemberian beberapa dosis pupuk fosfat menunjukkan hasil yang berbeda tidak nyata pada seluruh variabel pertumbuhan. Variabel hasil menunjukkan hasil berbeda nyata, namun berbeda tidak nyata pada pemberian beberapa dosis pupuk fosfat. Karakteristik tumbuh menunjukkan hasil yang berbeda tidak nyata, namun berbeda nyata terhadap variabel nisbah berat kering daun dengan berat kering akar, nisbah berat kering total hijauan dengan berat kering akar dan luas daun. Pemberian beberapa dosis pupuk fosfat menunjukkan hasil yang berbeda tidak nyata. Dapat disimpulkan penanaman tanaman kelor memberikan pertumbuhan dan hasil yang lebih baik pada tanah regosol dan latosol dibandingkan pada tanah mediteran. Pemberian dosis pupuk fosfat 50 kg/ha dan 100 kg/ha belum memberikan pengaruh terhadap pertumbuhan dan hasil tanaman kelor. Kata kunci: pertumbuhan dan hasil, tanaman kelor, jenis tanah, dosis pupuk fosfat

Abstract

The aim of this study are to observe the level of farming income in fattening local rabbits which were given a basic feed of carrot leaf waste which was supplemented with concentrates in different levels. This study uses a Randomized Block Design (RBD). Twenty male rabbits aged 7 weeks were divided into four treatments. The treatment of concentrate level 0g (R0 / control), 15g (R1), 30G (R2), and 45g (R3), each consisting of five rabbits used individual cages measuring 70cm x 50cm x 50cm. Forage feed in the form of carrot leaves is given ad libitum. The data used is primary data and secondary data. Management is explained descriptively based on observations. While the analysis of level income in fattening local rabbit is seen based on cost analysis, income analysis, R / C ratio analysis and BEP. The results showed that the largest total revenue was treatment of R3 Rp. 397,350.5 - with a total cost of Rp. 333,823. Based on cash costs, the highest total income is in treatment R0, which is Rp 113,631.9 with an R/C ratio of 1.47 while the revenue is treatment with the addition of concentrate is lower at Rp 83,301.6 (R1); Rp.69,658.1 (R2) and Rp.66,526.5 (R3) as well as an R/C ratio of 1.30 (R1); 1.24 (R2) and 1.19 (R3). BEP unit and BEP prices for each treatment are 2 head (R0); and 3 head (R1); (R2); (R3) with a price of Rp. 48,043.6 (R0); Rp. 54,819.7 (R1); Rp. 58,888.4 (R2) and Rp. 66,764.7 (R3). It was concluded that the addition of concentrate was still less profitable compared to carrot leaf-based maintenance without the addition of concentrates.
