Abstract

AbstractThe coconut waste water contain some nutrients, micronutriens, and minerals such as vitaminC, biotin, riboflavin, folic acid, amino acid, carbohydrate, calcium, phosphorous and iron.The product of coconut waste water is popularly known as nata-de-coco. Besides that, thecoconut waste water can also produced as alcohol beverages like coco cider. This researchwas conducted in order to observe the effect of sucrose addition and fermentation time onthe characteristics of coco cider, and to determine the best characteristics of coco cider.This research is expected to provide the information about the amount of sugar should beadded and fermentation time in production of coco cider. The design experiment used in thisresearch was the randomized complete design with two factors, i.e. the ratio of sugar added(5, 10, 15, and 20%) and the fermentation time (2, 4, and 6 days). The variables observedincluded alcohol content, total sugar content, pH, and sensory evaluation such as taste,aroma, and overall acceptance. The results indicated that the interaction between sucroseaddition and fermentation time significantly affected the alcohol content and total sugarcontent of coco cider, the more the sucrose added and the longer the fermentation time, thehigher the alcohol content and the less the total sugar content. The sensory evaluationindicated that the good coco cider was produced from 10 percen of sucrose and fermentedin two days with the characteristics: the score of taste, aroma and overall acceptance wasbetween 3 and 4, alcohol content was 5.3, pH was 3.9, and total sugar content was 10.75percents.

Abstract

AbstrakGreen open space (GOS) is a very important component in the arrangement of urban space,because the GOS has the function of ecological, aesthetic, social, cultural, and economic.Calculating of the GOS can easily be done in area that are enable for such purposes asurban forests, recreational areas of the city, as well as agricultural areas. However, for theland use consisting of non-GOS and GOS such as settlement, calculation of the GOS will bequite difficult. This research was conducted to measure the percentage of the GOS in settlementareas in the Denpasar city using remote sensing and geographic information systemtechnology. The results of this study showed that the percentage of the GOS in the settlementsarea of Denpasar ranged from 2.97% to 30.01%, with an average value of 14, 43%, and astandard deviation of 7.32% or 182.98 m2. The majority (50%) of the percentage of the GOSin the settlements area in the Denpasar city classified as moderate (10– 20%), 32% are low(<10%), and only 18% had a high percentage of the GOS (> 20%). Factors that influenceto the percentage of the GOS in the settlement area of Denpasar is the location of thesattements and the land area per housing unit.

Abstract

AbstractThe agricultural sector has multi-functions covering the food production or food securityaspects, the increase of farmer welfare or the eradication of poverty, and the preservation oflife environment. The analysis of the supportability of the agriculture sector environment isusing the land supportability approach based on land productivity, which is conducted bycomparing between the supply and demand of land for the population in a certain region.By this method, the general description whether the supportability of land in a certainregion is on surplus or deficit can be understood. The objective of research is to analyze thesupportability of agriculture sector environment based on land productivity. The approachused in this research is quantitative descriptive, while the analysis tools used are: descriptiveanalysis; the analysis against the supply and demand of land based on the calculationmethod suggested by The Decree of The State Minister of Life Environment No.17 of 2009.The Result of this research indicates that the status of environmental supportability ofBangli District on 2011 is shown by land supply (SL) which reaches 167,947.58 Ha andland demand (DL) which attains 74,173.77. These figures are based on the land supportabilityapproach that emphasizes on the land productivity in meeting the demand of biologicalproduct of the region. The comparison between land supply and land demand will facilitatethe environmental supportability status, which is in the surplus category that is SL > DL.

Abstract

AbstractDevelopment of crude palm oil industry in Indonesia and Malaysia have been able tochange the map of world vegetable oil in a short time. In 1985, Indonesia palm oil productionreached 1.3 million tons. However, in 2007 Indonesia has surpassed the total production ofCPO Malaysia. Indonesia’s CPO total production in 2011is 23 million tons. To producethat amount of production volume, there are at least 4 million ha of land to produce rawmaterial for the factory. With the next target of 50 million tons of production will of coursebe a lot of land to be prepared or converted. However, the increasing of CPO production isnot always have a positive impact. Forest damage caused by the opening of oil palmplantation and is still a lack of consideration to increase CPO production through increasedproductivity of the land received many responses from various parties environmentalists.Approximately 400,000 ha of forests in Indonesia per year be converted into oil palmplantations. The use of forest land for oil palm plantations is one of the growing threat ofIndonesia’s CPO production so necessary to control the development of this industry.Thispaper provides an alternative optimal solution to the development of palm oil industry bybuilding a decision support system that integrates GIS with spatial analysis modelsesspecially multicriteria decision making. This spatial based decision support system has acapability to accommodate the limitations of land development, environmental constraints,transportation facilities and transportation networks as well to get the optimal CPO industrydevelopment decision.

Abstract

The surface area of a photocatalyst is an important factor that effect decomposition process of colored wastewater. Increasing the catalyst particle surface area will increase the UV light absorbed thus enhance the photacatalysis process. Bulk TiO2 will have the higher surface area if it is made in the nano size. As a photocatalyst, nanoparticle of TiO2 is more efficient than bulk of TiO2. The nanoparticle of TiO2 can be made in various ways, for example by simple heating method. In this study, the synthesis of nanoparticle TiO2 was investigated by optimize the amount of polyethilene glycol (PEG 200) used and the annealing temperature. The amount of PEG 200 was varied between 6-18 ml. Moreover, the annealing temperature was varied in the range of 600-700oC. After synthesizing, the nanoparticles of TiO2 then characterize by using scanning electron microscope (SEM) to observe the morphology, and by using the X-ray difraction (XRD) to find the crystal structure and the particle size. Based on the characterization, it was found that the smallest nanoparticle of TiO2 have a 29 nm in size was produced by using the 12 ml of PEG at the annealing temperature of 600oC.

Abstract

AbstractFish culture and shrimp culture has been developing rapidly during the last few decades, itis due to the increase of fish and shrimps demand. Increasing aquaculture activities especiallywith semi-intensive and intensive system have significant effect on waste production, whichhas to be removed or to be reduced quickly because will effect on fish in rearing tank andenvironment when through away to environment such as river and sea. The objective of thisstudy was to know the capability of corrugated plastic to remove or to reduce ammonia,organic matter and Suspended Solids (SS). The result of the study showed that theconcentration of ammonia, organic matter and SS in waste water reduced after were passedto corrugated plastic tank. Reducing of ammonia, organic matter and SS that occurred inshrimps rearing tank for culturing shrimp with treatment different protein concentrationcontain in meal fish were 32% and 28% with removal efficiency for ammonia were 10.95%and 14.37%; organic matter 49.02% and 19.94%; SS were 35.46% and 22.22%. Thistreatment can minimize increasing rate of ammonia, organic matter and SS, thus thistreatment can maintain water quality in rearing tank. So, it can be concluded that corrugatedplastic had capability to reduce or remove of ammonia, organic matter and SS.
