Abstract

One factor affecting the quality in the construction section is the qualit of the work force. As we have seen in the last decade, the order of life in general and the order of economic, in particular, is undergoing to shift the paradigm towards global. In one side, the opportunity of cooperativeness among countries become wide open, the competition among countries increasingly tight. The un-competitive countries will be wiped out by those free trade and only the competitive countries will survive. To enhance the ability of competition in the free trade, required capabilites and competitiveness of power of human resources. The ability or the competence of the human resources in the construction services sector, is the only active resources that can determine the stability of the construction process. Construction of labour in conditions more commonly known by the constructors (construction’s craff) is the mostadvanced involved and deal directly with the implementation of a construction site. As a builder of the most advanced labor course must have specialization and competence in specific areas and certified. This is important and needs to be prepared within the framework of the current workforce in the era of liberalization. Given the specialization and certification of construction of Indonesian workers are expected to be accepted and able to compete with foreign construction workers. Besides having the competence and certification of construction workers are expected to not be labeled as low labor who only follow orders from the foreman, but also can take the initiative and be proactive to avoid failures during construction. One way that can be taken so thatworkers have the adequate specialization and competence is to conduct training and certification required by the engineer.Keyword: workforce, competence, certified.

Abstract

ABSTRACTDemak Great Mosque is a mosque of historical heritage during the Islamic kingdoms in the 14th century. Until now, this mosque still has an important share for the community as a place of religious worship and considered sacred. Against this background and the social conditions of society have developed, there is an indication that the Great Mosque of Demak has its own meaning on the spaces within the mosque-related to sacred and profane. The purpose of this research is to identify the sacred and profane space in the architecture of the Grand Mosque of Demak and identify the factors that influence the formation of the properties of the space. This research uses rationalistic approach and deductive qualitative method. The result of this study reveals that in its use, the spaces at the Great Mosque of Demak are divided into a room that is not worldly (sacred) and the room that is worldly (profane). Space that is (not worldly) is liwan and pawestren. While the worldly room is pawestren and porch. Factors affecting the sanctity of space are physical barriers and holiness of worship space. While sanctity becomes a legitimate requirement of worship activities, so it becomes the main requirement of the sacred or not a place.Keywords: Demak, Mosque, Profane, Sacred ABSTRAKMasjid Agung Demak adalah masjid warisan sejarah selama kerajaan Islam di abad ke-14. Hingga saat ini, masjid ini masih memiliki andil penting bagi masyarakat sebagai tempat ibadah dan dianggap sakral. Dengan latar belakang ini dan kondisi sosial masyarakat telah berkembang, ada indikasi bahwa Masjid Agung Demak memiliki maknanya sendiri di ruang-ruang di dalam masjid yang berkaitan dengan sakral dan profan. Tujuan dari Kajian ini adalah untuk mengidentifikasi ruang sakral dan profan dalam arsitektur Masjidil Haram dan mengidentifikasi faktor-faktor yang mempengaruhi terbentuknya sifat ruang. Kajian ini menggunakan pendekatan rasionalistik dan metode kualitatif deduktif. Hasil Kajian ini mengungkapkan bahwa dalam penggunaannya, ruang di Masjid Agung Demak terbagi menjadi ruangan yang tidak bersifat duniawi (sakral) dan ruangan yang bersifat duniawi (profan). Ruang yang (bukan duniawi) adalah liwan dan pawestren. Sedangkan ruang duniawi adalah pawestren dan serambi. Faktor-faktor yang mempengaruhi kesucian ruang adalah penghalang fisik dan kesucian ruang ibadah. Sedangkan kesucian menjadi kebutuhan ibadah yang sah, sehingga menjadi kebutuhan utama yang sakral atau bukan tempat.Kata kunci: Demak, Masjid, Profane, Sakral
