Abstract

The airflow patterns around traditional Balinese buildings cannot be estimated by experiment method nor using modern buildings, since the position and the function of a building on a cluster of traditional Balinese buildings are linked each other. It is not correct if the investigation uses an isolated building and symmetrical method in order to understand the airflow patterns of all buildings. Numerical method based on finite volume is used in this simulation since it gives quicker analyses and capable of delivering more detailed and comprehensive information about the flow structure around 3-dimension buildings. Results show that numerical method gives more accurate prediction of airflow patterns around traditional buildings.

Abstract

Abstrak. Karena terbatasnya lahan yang tersedia di kodya Denpasar, pembangunan ruang bawah tanah khususnya pusat perbelanjaan dan perkantoran dewasa ini telah semakin meluas. Banyak bangunan komersial yang kini telah memiliki ruang bawah tanah, namun karena perencanaan pengkondisian udaranya yang kurang baik, menyebabkan kurang optimalnya penggunaan ruang bawah tanah tersebut untuk aktivitas dan egiatan manusia.Penelitian ini bertujuan untuk membandingkan besarnya pertukaran panas pada dinding bangunan di bawah tanah. Pertukaran panas tersebut selanjutnya dipergunakan untuk mengetahui tingkat kenyamanan termis dari penghuni dengan jalan menghitung laju metabolisme tubuh manusia. Material selubung bangunan yang baik adalah material yang mampu mempertukarkan kalor sekecil – kecilnya serta menghasilkan laju metabolisme tubuh yang serendah – rendahnya. Dalam penelitian ini akan diuji beberapa kombinasi material dinding bangunan agar mampu memenuhi kriteria tersebut. Kajian terhadap kombinasi material ini untuk mencari susunan terbaik dari material penyusun selubung bangunan. Ditemukan bahwa kombinasi semen dan pasir, batu bata dan batu palimanan memberikan pertukaran panas terkecil dan kenyamanan termis terbaik bagi metabolisme tubuh.Abstract. Due to the land limitation in Denpasar area, development of underground especially for shopping malls and offices was growth rapidly. Most commercial buildings have underground area, but the failure on the design of air conditioning system caused the un-optimize of underground area for activity and human living. This research aims to compare the heat transfer rate on the wall of underground buildings. The heat transfer rate is used to understand the thermal comfort level of occupants by taking into account the human metabolic rate. The best material of buildings envelope must be able to transfer the smallest heat between the room to its surrounding and produce the smallest metabolic rate of occupants. This research compares several kinds of material in order to find those criteria. It found that combination of cement, brick and palimanan stone have been able to produce the smallest heat transfer rate and metabolic rate of occupants.AbstrakKarena terbatasnya lahan yang tersedia di kodya Denpasar, pembangunan ruang bawah tanah khususnya pusatperbelanjaan dan perkantoran dewasa ini telah semakin meluas.

Abstract

Sukawati District, Gianyar Regency is one of the tourist attractions anddestinations. Sukawati has Sukawati art market and Guwang market, art shops,craftsmen, wood carvers, painters, traditional and contemporary artists. They all completethe atmosphere at Sukawati. As a result, more and more people intend to build housesthere for which more and more electric energy is needed. This study was conducted toevaluate the use of electric energy at Sukawati District. The problems are formulated asfollows: how electric energy is used; how comodification takes place; how thegovernment and Perusahaan Listrik Negara, abbreviated to PLN (the Utility Company)dominates people and how the people resist the government’s hegemony, what are theeffects and meanings of the electric energy used at Sukawati District.Qualitative method supported by quantitative data, which characterize CulturalStudies, was adopted in this study. The data were taken from primary resources andsecondary resources. Qualitative method was eclectically employed for analyzing thedata supported by the theory of consumer behavior, the theory of comodification, thetheory of hegemony, the theory of knowledge and power and the theory ofdeconstruction. The results of the study were formally presented using tables, graphs andpictures and were informally narrated.The results of the study show that the increase in the number of population hasresulted in the increase in the number of traditional houses without/with slightmodification and modern houses. The rise in the number of houses has resulted in the risein electricity needed for illumination, mechanical purposes and so forth. The peopleliving at traditional houses use less and simpler electric utilities than those living atmodern houses. The electric utilities used are highly influenced by both internal andexternal factors. The advertisements of electric utilities also contribute to the use ofelectric utilities, meaning that electricity has touched what is required by the people atSukawati District. By referring to the 1945 Constitution, the PLN has dominated thedistribution of electricity. This has been used to comodify electric energy by changing itsstatus into a limited liability company, and to increase the basic rate of electricity (tarifdasar listrik, abbreviated to TDL) with its various scenarios socialized through massmedia. The government and the PLN dominate the community to accelerate their comodification practices. Such a dominance or hegemony is resisted by the traditionalpeople by strengthening their Balinese identity through the preservation of Balitraditional houses. Electricity has covered all the banjar/dusun (neighborhood under avillage) resulting in different effects such as giving up bathing in the public bathingplace, the extinction of informal communication among the people, renegotiation ofsacred values, change in orientation of the sekas (the traditional groups established forparticular purposes) from being orientated their activities to non economic motivationsinto economic ones. The different backgrounds of the people at Sukawati District havecaused the meaningfulness of the availability of electricity to vary.

Abstract

Traditional Balinese reasoning of zoning area follows the physics of microcosms (bhuwana alit) and macrocosms (bhuwana agung). According to four palm leaf manuscripts (named Lontar) the Asta Kosala, Asta Kosali, Asta Patali and Swakarman [anonymous], the housing area is divided into nine regions. The region is then named into three sub-areas called nista, madya and utama (poverty, middle, and primary areas, respectively). In traditional Balinese architecture, people follow the hulu and teben (upward and downward directions, respectively). Upwards and downwards directions are defined following the movement of the sun or the mount - sea direction. Sunrise is upward and sunset is downward, or the mount is upwards and the sea is downwards. The Balinese make a clear differentiation between the dwellinggrounds and the unlived parts of the village, those for public use such as temples, assembly halls and market. The village is a unified organism in which every individual is a body and every institution is an organ. The heart of the village is the central square, invariably located in the center of the village, at the intersection of the two main avenues. Consequently, the crossroads are the center of a rose of the winds formed by the entire village, the cardinal directions mean a great deal to the Balinese and the crossroads are a magic spot of great importance [Covarrubias, 1972].
