Abstract

AbstrakThe present study aimed to find out whether persuasive messages with descriptive normsand norms of reciprocation were better than the standard message in increasingparticipation in hotel’s reuse linens and towels program and to know whether similarstudies conducted in the individualistic culture of the United States could be replicated forthe Indonesian collectivistic culture. The study started by printing four different cards withstandard, standard with bigger fonts, descriptive norms, and norms of reciprocationmessages. Cards were placed in rooms of a hotel located in Bali. Results show that cardsprinted with descriptive norms and norms of reciprocation messages were indeed moredominant than the standard one in increasing participation in linens and towels reuseprogram. The results were similar to those conducted in the United States.

Abstract

According to the Balinese culture, there are some classifications of plants, such as: medicinal plants, ceremonial plants, commodity plants, horticulture, and magical plants. Due to it’ very importance value, culturally, there is a special day for the existing plants, called tumpek uduh, where a special offering is intended to the god of plantation. In this article is drawn function of leaves and fruits as a material for offering. Analysis is focused on the use of fruits as pala gantung, pala bungkah or tuber for the offerings to the god. The leaves are used for religious ceremony in term of panca dhala or asta dala. In composing the offerings, there is a guidance derived from tatwa pangider-ideran (point of compass). The used of leaves and fruits, is based on the color of leaves and fruits. The goals are for preserving/ conserving and peace-full fitting of nature. The liquid of young coconut fruits are used for the process of purifications materials, places, and the symbols of religious matters. Starting from east direction: nyuh bulan, east-south: nyuh rangda, south direction: nyuh udang, south west: nyuh surya, west direction: nyuh kuning, west-north: nyuh be julit, north direction: nyuh mulung, and the middle: nyuh sudamala. That is the respective-, dedicative offerings from human being to the nature by making use of materials for the feacefull, safety, and sustainability of the nature itself.

Abstract

Usaha yang dilakukan secara terus menerus dalam rangka mengurangi emisi CO2 untuk mencegah terjadinya pemanasan global telah mendorong penggunaan energi baru seperti biomasa maupun sampah sebagai bahan bakar alternatif pengganti energi bahan bakar fosil. Akan tetapi, bila bahan bakar biomasa/sampah dimasukkan pada sistem pembakaran fluidized bed, evolusi zat volatil akan terjadi sangat cepat. Ini dikarenakan oleh tingginya laju perpindahan panas oleh material hamparan di dalam ruang bakar sehingga zat volatil hanya berevolusi di sekitar tempat pemasukan bahan bakar. Karena ketidakcukupan oksigen di bagian atas ruang bakar maka pembakaran sempurna sangat sulit terwujud. Formasi hidrokarbon sering terjadi dan diantisipasi akan memunculkan dioksin pada gas buang. Evolusi volatil juga menyebabkan temperatur sangat tinggi di sembarang tempat pada ruang bakar dan kondisi ini akan menyebabkan formasi emisi NOx . Penelitian ini bertujuan untuk menangkap karbon dari evolusi zat volatile yang terjadi pada pembakaran sistem fluidized bed berbahan bakar sampah. Karbon ditangkap dengan menggunakan partikel berpori sehingga terbentuk karbon-deposit. Pada penelitian ini, karbon-deposit dibakar kembali pada suhu pembakaran fluidized bed untuk meningkatkan efisiensi pembakaran. Dispersi horisontal karbon-deposit di atas hamparan material diukur berdasarkan besarnya laju pembakaran, skala horisontal ruang bakar dan dispersi horizontal karbon yang terbakar. Dengan memperhitungkan tingkat oksidasi dan konsentrasi oksigen pada pembakaran karbon-deposit, model perhitungan yang dimodifikasi dari model Kunni-Levenspiel dikembangkan untuk menggambarkan dispersi horizontal karbon-deposit tersebut. Hasil eksperimen dapat dibuktikan sama dengan model perhitungan yang dikembangkan.

Abstract

Research is aimed to utillize archaeologicxal data sources ( artifact, isncription, manuscript) toinventory and study royal garden conception in Balinese kingdom period ( X – X Ceturies). It was carried outby research method. Firstly data was collected by literature study, observation, and interview. Then collecteddata analylized by descriptive qualitative techniqueResults of the research showed as follows. Royal garden establishment were affected by environmentaland cultural elements. Environmetal elements consist of physical and biological elements. Most importantphysical elements which very determined for garden establishment were water resouce, climate (24 0 C – 26 0C ), and topography ( 0 % - 3 %).Biological elements included vegetation (floweral and sacred trees such as menuh, angsana, bodhi,yellow coconut tree), and fauna include frogs, birds, fish,bumblebee and others.Meanwhile cultural elelementsrelated to social an cultural values, religious value, technology of hydrology, sicence of etnobotani ,planology,art , and social behavior.Function of the the royal garden were : (1) as a place to seek a quiet atmosphere, (2) a place forpurification and mediation, (3) as supplier of ritual equipments and conservative function, (4) as a suitableplace for study, (5) as a place to manage state policies, (6) for recreation and entertainment, (6) symbol ofpolitical stability and state prosperity.Royal garden conception was much affected by availablity of water resouce.There was a tendency thatthe garden which established was not just intended to honor a living king, but it also purposed to worshipking’s achestors and others divenes. The royal garden design is a inseparated design of capital kingdom’smasters plan. Since the royal garden was intergrated with a temple, so there was a tendency to choose sacredspace or sacred compass point ( east, north, or north-east) for gadern establishment. This concept pattern wasbased by cosmic conciousness to maitain balance and harmony between macrocosm (bhuwana agung) andmicrocosm (bhuwana alit or kingdom state) in order to reach peacefulness, properity and welfare life on earth.

Abstract

Different methods of watershed management have different technical and organizational problems. First, watershed management approach which was based on admisitrative region had clash of interest and authority. Second, river as resources of flow was not restricted by administrative boundary and technically there were impossible that flow of river stopped or switched to other regions because of the authority of every organization or institution. Consistent with technical and organizational problems above, watershed management based on space planning or government autonomy tended to be unoptimal, because it was not pararell with nature, characteristics of river flow (hidrologically), nor administrative or technical boundaries. In this condition, a new frame of watershed management needed, which had systemics frames, based on systemtematic thinking. One of tools of analysis which could be applaid was soft systems methodology (SSM).

AbstractDredge is known as cockle collector which is not selective to the shell size and its operationdamages the cockle’s resources. The objectives of this research were to obtain better dredgeconstruction which was more productive and selective to the cockle size. The end of theteeth was bent 30o to increase number of the catch. Separator was used to make the dredgebecome more selective for the shell size. In this research, gap between separator grids wasadjusted to economical size of cockle Anadara granosa, which was 40 mm long of shell.Results showed that dredge with 30o bended teeth caught 919 cockles, or 2.18 times morethan standard teeth of dredge (412 cockles). The using of separator made dredge becamemore selective. It only retained cockle Anadara granosa and Anadara antiquata with lengthof shell l e” 39.96 mm and l e” 35.11 mm.

Abstract

This study aims at investigating: (1) adolescent lexical knowledge about traditional medicinal plants from ecolinguistic perspective and (2) adolescent attitude toward traditional medical plants and its effect on ecology and ecolinguistics as an effort at preserving environment and lexis of medicinal plants. This study was conducted to 125 adolescents in Buleleng regency in 25 villages in 9 districts. The data were obtained through interview, observation, and lexical competence test. The data were processed descriptively. The result shows that the adolescent lexical knowledge about traditional medicinal plants is as follows. 28 rural adolescents (37.33% ) has an adequate knowledge , 47 (62.66%) an inadequate knowledge and 9 urban adolescents (18%) an adequate knowledge, 38 (76%) an inadequate knowledge and 3 ( 6%) a low level of knowledge. Ecolinguistically, this has an effect on reduction of lexical forms on the part of the adolescents. Fourty percent of the adolescent attitude showed disagreement with the assumption of backwardness and low opinion about the users of the traditional medicinal plants this is a positive attitude of the adolescents and is a good asset in the effort at developing faithful attitude, pride and awareness of the use of medicinal plants to preserve the ecology and ecolinguistics.
