Abstract

This study aims to determine the effect of different protein and energy level on nutrient digestibility of bali cattle heifers. This research has been conducted in Farm cattle at Belok Sidan village Petang District, Badung Regency for 3 months. A total of 12 bali cattle heifers used in this study were divided into three groups based on body weight. The treatments consisted of four types of rations, a ration containing 12% crude protein and 2000 kcal ME/kg (treatment A), 13% crude protein and 2100 kcal ME/kg (treatment B), 14% crude protein and 2200 kcal ME/kg (treatment C), and 15% crude protein and 2300 kcal ME/kg (treatment D). The experimental design used was a randomized block design (RCBD). The observed variables were dry matter digestibility, organic matter digestibility, crude protein digestibility, ether extract digestibility and crude fiber digestibility. The results showed that fed ration with different protein and energy content has not significant different (P>0.05) of digestibility of dry matter, organic matter and crude fiber respectively with with values ??of 65.77-71.17%; 67,57-72,60%; and 53.13-54.32%. While for variable of crude protein digestibility and extract ether digestibility, fed rations with different protein and energy content yielded significantly different values ??(P<0.05). Crude protein digestibility and ether extract ether digestibility of treatment D were 23,64% and 16,56% higher respectively than treatment A. Based on the result of this study it was concluded that the increase of protein content of ration from 12% to 15% and metabolized energy from 2000 to 2300 kcal/kg does not affect the digestibility of dry matter, organic matter and crude fiber, but can improve the digestibility of crude protein and ether extract of bali cattle heifers. Keyword: protein and energy, nutrient digestibility, bali cattle heifers

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

Millennium Development Goals has been mandated to always strived to reduce therate of loss of biodiversity as a very valuable genetic resources. Bali swine germplasmwhose condition is increasingly threatened by the inclusion of various types of pigs thathave the ability to produce more meat. Last post five years, Bali’s pig population in theprovince of Bali continued to decline and reached until 30 percent (243 310 head) of allpigs in Bali (817 489 head). Of the pig population in Bali as much as 53 percent in Buleleng.Bali pig role in socio-cultural activities and opportunities to explore the culinary marketrequires no effort to increase productivity in a sustainable pig Bali. Various strategicapproach to the development and preservation of pig Bali described in this paper as aneffort to accelerate the achievement of the millennium development.

Abstract

Efforts made to achieve clean and healty environment should not merely put on the responsility of executive institutions only, but also all stakeholders who have concerned on environment including house of representatives. The Environmental Caucus of the house representative are expected to improve survailance, budgetting, as well as release of pro-environment regulations which are predominantly related to environmental management. On carrying out sustainable development, providing main attention on environment on any decisions and regulations made is a must. Therefore the existence of Environmental Caucus of the house representative is important because the institution can push any parties to make decission which are pro to the environment on the parliament levels. If we look at the challenge and chance faced by the Environmental Caucus of the house representative, strong commitment needed by their members to fight for pro-environment supporters and take environmental problems as priority on their political agenda.

Abstract

The experiment of sustainable technology application with casting organic fertilizer and styloassociation with King grass was conducted at Siut Cattle farm at Gianyar regency. The experimentdesign was a randomized block design arranged in Split-plot pattern and was replicated threetimes. The treatment consisted of two factors as follows: (1) two types of cropping systems as mainplot (King grass monoculture and King grass – stylo association), (2) four levels of casting organicfertilizer as sub-plot (0, 10, 20, dan 30 t ha -1). The variable studied were: forage production,production characteristic, and leaf characteristic. Leaf characteristic variable consisted of: leafarea, leaf color, and leaf thickness. The results showed that: casting organic fertilizer weresignificantly (P<0.05) effect on leaf area and leaf production. Cropping system was not significantly(P>0.05) effect on all of variable studied. There was no significantly interaction (P>0.05) foundedbetween cropping system and casting organic fertilizer on all of variable studied. The conclusion ofthese experiment were: casting application at King grass and its association with stylo wasincreased forage production at first regrowth. The optimal levels of casting organic fertilizer in Kinggrass monoculture and that association with stylo were 17.09 dan 16.41 t ha -1 respectively.

Abstract

Garbage is a problem that must be faced by the community, because garbage is a form of environmental pollution, where garbage can have an impact on public health, such as; odors, floods, destroy aesthetics, fire, greenhouse effect and so on. Household waste management requires active community participation so that the role of the government does not get heavier. Increase community participation in waste management in Denpasar City. In an effort to build the effectiveness of waste management in Denpasar City, it is necessary to develop a community-based waste management model in Denpasar City. The purpose of developing a waste management model is to actively involve the community in managing waste in Denpasar City. This study uses the Interpretative Structural Modeling (ISM) method approach by using elements of the affected community, elements of program objectives, elements of indicators to achieve goals, elements of the main constraints and elements of the institutions involved. In compiling the sub-elements from each element, it involves figures, experts, actors and activists in Denpasar City on community-based waste management. The results of the modeling show that the participatory role of the community is very important in reducing waste through reuse, increasing community involvement and implementing 3R activities. The main obstacle in waste management is the limited facilities and infrastructure for waste management and the unclear waste management organization. Possible changes are that law enforcement and waste regulations must be clear and the involvement of all stakeholders in community-based waste management in Denpasar City. Keywords: model; management; waste; society.
