Abstract

A study on “Efforts perpormed by hotels in Bali in looking after the environment” was undertaken in 2009, by utilising data from July, 2008 until June, 2009. Objectives of the study was for collecting data on any efforts undertaken by hotels in looking after the environment especially related to minimising water consumption, garbage handling, the use of chemicals (especially cleaning chemicals), minimising energy consumption and ecosystem conservation (measured from the proportion of natural vegetation). Data were collected from interviews, document checkings and distributing questionaires. Results of the study showed that in average water consumption of hotels in Bali was 115 litres / guest night. It was considered low, less than the benchmark of Green Globe/Earthcheck which was 1,300 litres / guest night. The average of energy consumption was 0.322 MJ per guest night, which was still much below the baseline levels / standard of 340 MJ / guest night. In average garbage/waste produced by hotels was 0.0309 litre/guest night. This was also much below the baseline of 6 litres / guest night. The use of biodegradable cleaning chemicals in the hotel was averaged 35% which should be a minimum of 50%. There were 22% only of hotels which used cleaning chemicals that were biodegradable over 50% (over the standard). In average the proportion of natural vegetation in a hotel was 29%. There were 43% of sampled hotels of which their natural vegetation was over the baseline of 33%. Thus, hotels in Bali should improved their performance in looking after the environment, especially dealing with cleaning chemicals and ecosystem conservation. In this regards, they should increase the proportion of the use of biodegradable cleaning chemicals and increase the proportion of land kept with their natural vegetation.

Abstract

This research was proposed to increased the potency of shanks, esspeciality their skin by hidrolising the collagen (by extrating with solvent) into gelatine products. This research was run on a Completely Randomized Design (CRD). The experiment was run in factorial designs of 2 x 3. Factor I was solven type chloroform-ethanol and heksana-etanol, Factor II was a combination of ratio of 1:1, 1:3, and 3:1. The variable in this research were pH, viscosity, rendement, protein, and fat of gelatine contents. Result of the research indicated that the pH value of gelatine was between 8.21-8.52. The solvent of chloroform-ethanol gave the best result (P<0.05) on the ratio of 1:3. Percentage of rendement of gelatine was highest obtained from chloroform-ethanol types compared with that of hexane-ethanol (P<0.05). The interaction combinations of chloroform-ethanol on the ratio of 1:1 would result in the rendement percentage to be higher than others (P<0.05). Otherwise, the solvent of hexane-ethanol might bring impact to the viscocity of gelatine (P<0.05) compared to chloroform-ethanol. The interaction combination of hexane-ethanol ratio gave the best result (P<0.05) with highest level of viscosity on the ratio of 3:1 and lower on 1:3. The content of gelatine protein was highest (P<0.05) for the combination of hexane-ethanol compared to that of chloroform-ethanol. The solvent of chloroform-ethanol types could degrade more component of gelatine fat (P<0.05) compared to that of hexane-ethanol. It could be concluded that the research that the content of gelatine protein from extraction by hexane-ethanol on the combination ratio of 3:1 brought the highest quality compared to others.
