Range of Types of Local Element Synthesis Forms and Non-Local on Villa Isola Building in Bandung City

. The Indis architecture of the 1920s to 1940s in Indonesia was a phenomenon of the formation of Dutch colonial buildings with high architectural value that still survive today. The shape results from combining modern European architecture with Indonesian vernacular architecture. The research uses a range theory approach to the type of architectural synthesis forms, architectural synthesis theory, local and non-local elements theory, architectural synthesis form theory, archetypes theory, and typology theory. The research methodology is carried out with qualitative and quantitative approaches. The qualitative approach is descriptive and interpretative research, where the data is more concerned with interpreting local and non-local architectural elements in the object of study. The quantitative approach is confirmatory to prove it under the research objectives. The results of the study are expected to provide an understanding of the range of types of synthesis forms of local and non-local elements; aspects that affect the range of types of synthesis forms; form, form, and type of architectural synthesis; the range type model of the architectural form on Indis architecture building.


INTRODUCTION
Currently, many architectural works do not have local characteristics, characters, and identities, so they do not have an identity under architectural developments.Architectural works that develop also do not have a form that is in harmony between function, form, and meaning due to the impact of globalization that occurs due to the rapid globalization of modern culture and architecture.According to Naisbit (1995), the pressure of stronger external influences will likely give rise to things that smell local.It is believed that globalization always gives rise to paradoxes where advances in communication technology are inevitable, and every country must support the process of globalization.
The influx of information from abroad and understanding architectural styles and material products greatly influences and colors the architectural climate.Hence, the influence of architecture from outside that is so strong will impact the sinking of local architecture.Indies architecture is vital in providing local and non-local characteristics and identities that can be used as a basis for conducting a more in-depth search in this study.This architecture is also one that contributes to the repertoire of architectural development in the early 1900s (1920 -1940s).
The process of architectural synthesis in Indies buildings produces 1. new forms of architectural synthesis, 2. the dominance of local forms of architectural synthesis, and 3. predominance of non-local forms of architectural synthesis.
The form of architectural synthesis can be seen from the expression of its scoping elements, namely, roofs, walls, and floors, with various forms influenced by local and nonlocal elements that refer to the form of Indian regionalism and European modernism.Thus, in the process of synthesis of Indies buildings, there is an understanding of the range or limit of the dominance of synthesis forms that are influenced by local and non-local elements through the expression of the scope of the building.
Indie buildings are architectural works that observers can enjoy from the expression of architectural forms that display the results of climatic adaptation and cultural In the context of Indis buildings, the word Indis comes from the Dutch 'Nederlandsch Indie' or Dutch East Indies, which is the name of the Dutch overseas colony which geographically includes a colony in the islands called 'Nederlandsch Oost Indie .'Themention of this indie building refers to the unique characteristics of the building of a certain period and is related to the historical realm.About traditional house building, Parmono Atmadi mentioned that the understanding of traditional architecture is sometimes different.Some are sufficient based on the shape of the roof and components that are architectural patterns alone, following several rules inherent in traditional architecture (Soekiman, 2011).The range of forms of architectural synthesis in this study deserves to be raised because, in the past, research has never been questioned.It is hoped that this research can determine various types of architectural forms, referring to the classification of form types and function types, which ultimately play a vital role in determining the characteristics and identity of architecture, especially Indies architecture that has developed and is in several cities located in coastal and inland cities.
Based on phenomena related to the architectural synthesis of Indies buildings, the interesting issues to be studied in this study are: (1). the range of forms of synthesis of

Study Case Selection
The selected study case is an Indies building with characteristics according to the research objectives.The selection of Indies buildings in the city of Bandung is very relevant to the city of Bandung, which has a very representative city architectural identity and was once dubbed as the city of flowers (Paris van Java) with its Garden City concept and in the Dutch colonial period was planned as the capital of the Republic of Indonesia.
The criteria for selecting study cases in this study are: Dwiyandana, Dani | 68

DISCUSSION
In the architectural drawing of the Villa Isola building below, it is found that the flat roof is supported by a massive wall curved out (convex) with a symmetrical wall and window arrangement pattern.The existing structure in the Villa Isola building is a wall structure with construction using poles, steel beams, and concrete.The construction of the roof frame uses a steel frame.Massive walls with window openings of steel construction.
accommodation.Architectural adaptation to the humid tropical climate in Indonesia is carried out by climatic adaptation manifested through local architecture called tropical architecture.In contrast, architectural adaptation to culture is carried out by cultural adoption from indigenous and immigrant cultures.In non-local aspects with non-local identities (modern elements and technology) manifested through modern Dutch colonial architecture.Therefore, Indian buildings, through their scope, have the potential to display expressions of local and non-local elements.The term climactic expression in architecture is described as the inherent characteristics of architectural forms that are manifestations in response to climate for buildings to function correctly.Cultural expression is defined as everything related to cultural elements, both physical and non-physical, that develop and are still recognized by the local community and create a local identity attached to the architectural form through symbols or signs.Thus, climatic and cultural expression is something that can mutually reinforce or negate each other, which is displayed through the form of building scope.The ideal form of building coverage can adapt to the climate and simultaneously adopt the local culture.Climate in the tropics is a significant consideration in architectural design.In humid tropical climates, there are 3 (three) tropical design paradigms built based on different emphasis on architectural language, the appearance of tropical buildings, and assumptions on the fulfillment of the scope function for comfort in the building(Joo-Hwa Bay, 2001).Indies building architecture is formed from the embodiment of a synthesis of local and non-local elements that still survive today because it has characteristics such as 1.reflecting the architectural style of Indonesian vernacular identity; 2. bringing modern architectural styles to Indonesia which were influenced by modern architecture (Europe) and became the beginning of the development of modern architecture in Indonesia; 3. reflects Indonesia's tropical modern architectural style; 4. reflects the traditionality and modernity of European modern building form types; 5. Bringing modern European architectural styles through the synthesis of local and non-local elements.LITERATUREThe city of Bandung has very diverse indies buildings with a complete form of architectural synthesis, including several famous indies architectural works from the Netherlands in 1920-1940, namely Schoemaker and Henri Maclaine Pont, with their Indian architectural concepts.The architectural design of Indies buildings recognizes two concepts(Widyarta, 2007), namely: (1) Schoemaker's concept of Indies architecture about modern tropical architecture and (2) Henri Maclaine Pont's concept of Indies architecture with modern traditional architecture.
