Evaluation of Real Estate Development Process in Sharia Housing Based on The Application of The Ideal Islamic Housing Concept

—The ideal Islamic housing concept should implement Islamic values holistically in the sharia housing project. The development process of sharia housing looks at housing as not merely a product but also implements shari’ah marketing methods and opens up opportunities for sharia investment in housing finance. Sharia housing with an ideal Islamic housing concept accommodates sharia values in various stages of development, starting from the initial idea formation, feasibility studies, planning and design, funding schemes, employment contracts, marketing selling and buying methods, to estate management. In housing development, the role of investors is important to control the quality of a product that is being developed. A case study strategy was used, with descriptive statistical analysis in evaluating the development process of the Islamic housing concept. Medina Residence 1 was taken as the case study based on their promotion in which they applied the Islamic housing concept in the development process. The evaluation result of the application Islamic housing concept in the development process at Medina Residence 1, shows that the Islamic housing concept has been applied and received a very satisfying response from investors. Therefore, sharia housing developers need to pay attention to it to implement Islamic value in housing development holistically.


I. INTRODUCTION
N the field of architecture, one of the most frequently developed sectors is the residential property sector, this is because the main need for people to live is increasingly rising. Therefore, there are many new residential property development projects for the community, both in the form of landed houses, midrise buildings, and highrise buildings. One of the residential property sectors that are currently emerging is the Islamic concept of residential property that applies religious values into housing. The application of these values aims to bring religious values closer together so that the residents get special benefits in their application [1]. The development of real estate with a specific theme becomes a branding that can attract consumers. Many developers have raised the concept of Islamic housing as the branding of developed housing products, but many housings with that concept have not met all the ideal criteria of the concept of Islamic housing both in physical and non-physical aspects, so an evaluation of the application of the concept in shari'a housing is needed [2]. furthermore, with the application of the Islamic housing concept, sharia capital investment opportunities will arise in the property sector for investors who are interested in investing in the development of the project. Based on the background and formulation that has been explained before, the question of this research is: How is the application of the ideal Islamic housing concept in the development process of shariah housing. The objectives of this study are evaluating the application of the ideal Islamic housing concept in the development process of the shari'a housing project.

II. THEORY AND METHODS
The definition of real estate activity itself is an attempt to increase the value of a property to produce a mutual benefit. One of the implementations of real estate is to convert less active or vacant land into buildings so that it produces a profit. The success of real estate development is determined by how the real estate process works. In developing real estate usually goes through several stages of the planning and design process [3].

A. Sharia Housing Development Process
The theory of real estate planning proposed by Miles is sufficiently detailed in discussing the process and stages of development in eight stages, each of which can be further translated with more specific supporting theories, so that this theory can be developed into a sharia-based housing development theory ' ah who apply Islamic sharia values from the early stages of development to the final stage [3].
The inception of an idea of shariah housing was developed residential real estate with the ideal Islamic housing concept, with the main market share is the people who want to get housing that can actualize Islamic values in it. The initial idea of the development of sharia housing must show the existence of a vision, mission, and goals that lead to the application of Islamic sharia to housing [2].
The refinement of the idea stage is the process of study and excavation of planning and design criteria with themes following the initial idea. In the development of shari'ah housing, this sharpening phase refers to the criteria that must be met to develop a real estate with the ideal Islamic housing concept. After the ideal Islamic housing concept, at the refinement of the idea, there are special programs that support the implementation/realization of Islamic sharia in life in housing [2].

Evaluation of Real Estate Development Process in Sharia Housing Based on The Application of The Ideal Islamic Housing Concept
The feasibility study is the final stage of the planning process which will then be continued with the physical design process of a project.At this stage, the architect's role is very dominant. In the development of Sharia housing, the ideal Islamic housing concept is actualized in a real estate project with a physical architecture that is suitable for branding with Islamic housing following the design and planning criteria that were formulated in the previous stage. One of the principles of Islamic housing is not located in disaster-prone areas, water catchment areas, technical irrigation fields, and flood areas so that the land can be declared feasible to be developed [2]. Also, in preparing the feasibility study must consider licensing and applicable regulations such as RUTR information, land use permits, location permits, environmental impact analysis, site plan approval, and developed land does not occur disputes and problems between developers and landowners so that no forced land acquisition occurred [2].
The Contract Negotiation stage in Sharia housing is the stage of formulating the project funding, implementation, and management schemes. In the context of Islamic economics, the funding system (finance), one of which is the Mudharabah system, is often used in sharia-based property development with profit-sharing schemes between stakeholders or capital owners and business operators, in this case, developers. This stage also discussed how the methods and schemes of project implementation and management, so that it will be discussed starting from the method of funding with investors, implementation with construction contractors, and management with management of housing that was developed. In the ideal Islamic housing concept, every negotiation of the sale and purchase of goods and services must bring benefits/benefits to the parties involved, then it is forbidden to use the Ribawi system [2].
The formal agreement is the process of contracting and officially signing of contracts between parties involved in sharia housing development projects. In the Shari'ah housing context, this process is called the Shari'a contract, the process of this agreement is the understanding and willingness of both parties to cooperate to develop real estate and carry out all the processes following the preceding articles. Also, a work contract is made between the developer and the contractor. Following the ideal Islamic housing concept, all agreements must be contained in official, clear, and not contradictory documents of Islamic Sharia [2].
The construction stage is the main process of real estate development. In this stage, a lot of actors were involved, including architect, structural expert, MEP expert, interior expert, acoustic expert, lighting expert, and estimator. While in the operational implementation required a project manager who will oversee and carry out the technical aspects of development. The marketing manager is needed during the implementation phase to get prospective buyers so that buyers can indeed or can immediately buy when the building construction process is completed in the context of housing, then the selected developers and contractors will carry out the physical construction process, in Shari'ah housing one of the most important elements in the area is the construction of worship facilities that are characteristic of Shari'ah housing so that in general developers will build these facilities  together with physical development housing. In the ideal Islamic housing concept, construction implementation must pay attention to the suitability of building and facility specifications that have been planned and promoted. Also, each stage of development must be carried out by the investor to control the quality of development results. Then every month there must be a sales report to investors to show the transparency of the business is managed. Completion and formal opening of real estate projects is the last step of construction, in this stage support utilities are connected, such as electrical, telephone, and other utility lines. So with a careful plan and complete permit management, this activity will not be hampered. Operational workers must be prepared before the project opening process. In the context of Sharia housing in general, it is marked by the handover of residential units to consumers, and at this stage, the investment process is still ongoing until the specified investment period is complete. During the process, the developer is obliged to provide dividends for the results of the project work to investors following the agreed contract. Following the concept of an ideal Islamic residential home handover process must be following the quality and Table 2.
