[ABSTRAK
Dengan dikukuhkannya industri Jasa Konstuksi sebagai bidang yangmenyumbang cukup banyak kecelakaan (Tahun 2005 Bereau Labor Statistics: terjadi200,000 luka-luka serius dan kematian 1,200 setiap tahun di Amerika. Dengankomposisi 7% dari tenaga kerja keseluruhan menyumbang 21% kematian kerja)sedangkan di Indonesia: Jasa Konstruksi menyumbang 31,9% kecelakaan kerja.Dalam kurun waktu bulan Januari hingga Agustus 2008 telah terjadi kecelakaan diJasa Konstruksi: sebanyak 6 kali di daerah Porvinsi Jakarta.Tenaga kerja yang terlibat dalam Sektor Jasa Konstruksi beragam: daritingkat Direktur hingga Subkon. Dalam kerja pelaksana dikenal dengan jenjangGeneral Superintendent, Manajer Proyek, Mandor, Pelaksana. Tingkatan Mandorhingga pelaksana dalam keseharian pekerjaannya dijalankan oleh subkon. Tingkatsubkon tersebut mempunyai pendidikan, pengalaman, pelatihan dan keahlian belumsesuai persyaratan K3.Meningkat dan pesatnya kebutuhan percepatan pembangunan konstruksiberhubungan dengan kompetensi pelaksana pekerjaan, sehingga perlu ada kebijakanpengamanan kerja serta bimbingan perilaku K3 pada pekerja subkon di lapangan.Seiiringnya pesatnya pembangunan konstruksi sesuai dengan percepatan darikebijakan pemerintah, akan memicu perusahaan untuk berhati-hati dalammenjalankan sesuai dengan kompetensi pekerjanya, antara lain dengan pemahamanakan perilaku K3 pekerja pelaksana di subkon, maka perlu diadakan kajianpemahaman perilaku K3 pekerja subkontraktor di Jasa konstruksi untuk mendukungtenaga kerja dengan menggunakan Knowledge-Based Error dalam pembangunankonstruksi hingga meredam kecelakaan kerja seminim mungkin. Setelah dianalisadari isi knowledge based error berdasarkan kepada perilaku pekerja yang terbesaradalah Tendency to haste (24,23%), Selective focusing (20,09%), Disregardingcontradictory evidence (18,66%).Dari keseluruhan hasil penelitian tersebut maka human error yang palingdominan dipilih untuk kajian adalah knowledge based error. Program errorprevention sangat diperlukan untuk mencegah terjadinya kasus human error secaraberulang.

ABSTRACT
As reported recently of accident and injury in the construction sector gainsignificant numbers. (In teh year of 2005 United States Bereau Labor Statistics:recorded 200,000 seriously injured and fatality amount 1,200 every year,composition 7% from all worker submit fatality 21%). Compared in Indonesia:construction sector gain 31,9% of accident and incident during January to August2008: accidents performed more than 6 times fatality in the Jakarta province only.The worker in construction varies from directors to sub contractors worker.Named such as: General superintendent, Project Manager, Site Manager, Engineer,Foreman (Mandor), and Worker. Classification differ from Foreman (mandor) to siteworker supplied by sub contractors (vendor). Level of education varies fromelementary school to senior high school, many of the workers did not have specialability as construction worker in regards of safety health and environment.In fast growing construction project nowadays as boost and recommended bygovernment, soon will be triggered safety implication in regards of constructionworker competences. Specially for sub contractors worker should aware of safety atwork, hazard at the worksite, safety sign and symbols. The main contractors shouldestablished daily safety briefing, short briefing and safety patrols. To cope themeaning of human error on safety behavior at sub contractors worker, need morestudy to avoid and minimalize accident and incident at constructions worker. Thestudy based on Human Error. After analysing worker human error based onknowledge based error, the main result are Tendency to haste (24,23%), Selectivefocusing (20,09%), Disregarding contradictory evidence (18,66%).In Conclusion of the study held, human error is chosen as dominant cause totrigger knowledge based error. To avoid and prevent continous case of human errorshould need error prevention programme., As reported recently of accident and injury in the construction sector gainsignificant numbers.
