Abstract

Ecology of language is interaction between language and its environment. Language can only exist if there are speakers and it is used a means of communication. Language is within the self (mind/soul) of the speakers, it functions as a means of social interaction (communication) also it is concededly created to communicate and it is the result of social life. The dynamics of language interrelated to its environment are affected by the relation between the user/use with the physical/natural, religious and social environment. The formulation of the relation concept applies life philosophy of Balinese society (Hindu) which is generally known as Tri Hita Karana (three causes of bliss) that in linguistic field by the linguists it is only differentiated into natural environment and social environment. This study classified language environment into three kinds according to life philosophy of Balinese and it apparently matched to the phenomenon of the use of Balinese Loloan Malayan language. Natural/physical relation significantly affected in the use of vocabularies related to traditional Loloan Malayan house, house on stilts (Rumah Panggung), such as the word kelam ?wood plank to close the spaces? (placed on windows/doors), sendi ?foundation of house?s pillars?, tontongan ?windows of house on stilts (Rumah Panggung)?, were barely unrecognized except the word sendi which was still found. In religious relation, the vocabularies such as ruah ?celebration?, tungsten ?customary ceremony?, nela?i/kepus pungsed ?the ceremony of loosened umbilical cord in babies?, lepas kambuhan ?the ceremony of forty days after babies? birth? and khitanan ?ceremony of circumcision for boys aged 4-12 years old?, were barely underused except the word khitanan in which the ceremony itself was still prevailed. The last, social relation showed the greatest dynamics because basically language existed depending on its use as a social means (communication). In this matter, there was accommodation of Loloan Malayan language with Balinese and Bahasa Indonesia which was absorbed through the process of adoption, for example the word pait ?pahit? (Balinese) and telepon (Bahasa Indonesia), and process of adaptation, such as the word kuping ?telinga? (Balinese) became koping and the word lain (Bahasa Indonesia) became laen.

Abstract

Sludge of waste treatment represent main problem of processing chemically because needing special handling. Processing of this mud cost money which quite a lot, at least 50% from expense of processing of waste water needed to to overcome yielded mud, as a result most in Indonesia this direct mud thrown to river or piled up. Treatment of sludge was composting with inoculate microorganism from several of sediment and soil. Phase of seeding was conducted by addition of NPK and other micro-nutrient in 3 L of basin. Growth of microorganism was measured of each every 2 day during one week with measuring value of biomass till reach price 2000 mg / L. Active mud as product inoculated to composting process of organic material with sludge. All active mud result of seed into each place of that is Place of A : active mud of river sediment of Badung, Place of B : active mud of moat sediment, place of C : active mud of fertile land, Place of D : without addition of active mud as control. Change of fastest physical happened at sample with addition of active mud from fertile land. Degradation of rate of C organic and highest total N happened at sample with addition from active mud of moat, while highest available K happened at sample with addition from active mud of fertile land. Rate of N highest total obtained by sample with addition from active mud of River of Badung and from fertile land. Product of composting process were fulfill SNI (19-7030-2004) for the parameter of physical that is temperature, color and odour

Abstract

The light intensity needs to adjust to produce suitability of illumination needs in room based on type of space function so it's possible to save electrical energy. Therefore, creation of energy-efficient lighting is very important so can be controlled. The purpose of this study is analyze and design a light intensity control device with remote control. This type of research is experimental research, which is research that doesn't require a comparison, which means the experiment is given treatment and measurements are made by the tool. The tool designed is a combination of several electronic circuits consisting of power supply, infrared emitting and receiver, digital circuit, relay driver and dimmer circuit. Analysis uses luxmeter as a measure the average light intensity and thermocouple as a measured quality of mean temperature room. The results are light intensity and temperature quality was carried out 3 times at (08.00-12.00 WITA), (12.00-16.00 WITA), (16.00-20.00 WITA) and mean was taken with 9 measurement points with total area of 36 m2 (initial color). The measurement didn't meet the standards of 295 lux and 28ºC, while when being treated it met the room comfort standards of 247 lux and 23ºC. This is due to influence of a tool to control the brightness of the lights. The results of the work are light intensity controller gives 10 stages of resistance values that adjust the brightness of incandescent light with an increasing count, indicating the initial value ranging from 0 to 9.

Abstract

Degradation of mangrove forest in Mahakam Delta were caused by conversion into ponds.These conditions resulted in a decrease in the benefits of the mangrove ecosystem, bothdirectly and indirectly. To restore the environmental conditions, the government rehabilitatingponds by applying sylvofishery pond system. This study aims to estimate the value ofexternalities mangrove areas converted to ponds in the Mahakam Delta and counting analysisfurther aquaculture with traditional extensive system as well as sylvofishery system. From theresult of study, it can be concluded that value of the lost benefits that reach Rp. 137,484,760,721, - / year of mangrove forests that  have been converted to ponds for  75,311 ha. NVPvalue was negative and BCR less than 1 for traditional extensive pond system which meansthat the use of ponds with extensive traditional system will suffer a loss and this business wasnot feasible at this time as well as the positive value of BCR and NVP more than1 for thesylvofishery pond system means that utilization of ponds with sylvofishery system will beprofitable and feasible at this time

Abstract

The research aims at identifying the concepts related to child-friendly city as perceived by parents in Yogyakarta municipality. A structured questionnaire is employed to collect the data on the ideal urban environment of a child-friendly city as perceived by the respondents. The respondents are widthdrawn from four spots of locations in the city used as child playgrounds, i.e: Sultan Palace Yard, Taman Pintar (Smart Garden), Gembira Loka Zoo and Open Space under the flyover of Lempuyangan Station. Concepts related to child-friendly city are explored and grouped through a factor analysis. From the process of factor analysis, four measures of ideal urban environment related to child-friendly city can be identified. They are policy, protection, environment and planning for children. The first three concepts are well suited with the Indonesian national policy on child-friendly city. Whereas the last concept, planning for children, needs special  attention as a part of the existing concept of policy, or it should be an independent concept that needs to be accomodated in planning norms, standards, procedures and manuals in an urban environment.

Abstract

Gerris marginatus is one fresh water insect distributed from temperate to tropicalareas. It can be found in almost every freshwater biotope, making them excellent objects forecological and biogeographic studies.  Most recent studies found that this water insect wasone good candidate for examining the effect of fresh water pollution.  This species showsmorphometric differences between male and female, but there has no studies examining thismorphometric differences particularly in tropical areas.  This study aimed to determine andinvestigate the morphometric differences between male and female and their sex ratio of G.marginatus in one of freshwater body in Bali.   Samples were collected from Jangu River atKarangasem Regency on February 2014.  Samples were preserved in 70 % awaiting foridentification and further studies. Identification was performed at Animal TaxonomyLaboratory, Biology Department. The results show that there were morphometric differencesbetween male and female of G. marginatus in tropical area.  Males were significantly largerof many variable measured compared to females. However, they also exhibit sex ratio biastoward females.

Abstract

This study concern to discuss about ideology wich talking about the used of ‘’saput poleng’’ in a big tree in Bali. Where for Hindus people means to remains the environment. But in fact that’s only just text, because some or maybe much environment be in big trauble. For example, ‘’Vila Bukit Berbunga’’ case in Tabanan and Buleleng region, the condition of critical area, in forest area is 3.538 ha very critical, 6.286 ha critikal, and 44.201 ha is alittle bit critical, and then all critical area is in 54.205 ha. Then the critical area far from forest area 84.885 ha. Based on Forest Departemen 2002, the damaged of forest in Bali is Caused by fired wich demage 544,19 ha; caused by people (illegal wood cutter) wich demage 83,17 m3/ph, and caused by ‘’pembibrikan’’ wich damage 5.245,77 ha. Beside that ‘’Galian C’’ erotion, tourism development (Bappeda Provinsi Bali, 2006: IX-14—IX-15). Is take a part to damage it. To prevent the damaged environment Balinesse has two way, there are ‘’sekala and niskala’’. Sekala way is make some low to protect forest area and niskala way is make some Hindus ritual.
