Abstract
Banyaknya permasalahan yang terjadi di lapangan pada saat tahap konstruksi disebabkan oleh adanya kesalahan pada fase desain. Permasalahan yang timbul pada saat tahap operasional dan maintenance juga beberapa timbul karena kesalahan pada saat fase desain. Namun pada saat ini sebagian besar perusahaan konsultan perencana telah mempertimbangkan konsep constructability dan maintainability dalam proses desain yang mereka lakukan. Hal tersebut karena kesadaran mereka akan manfaat optimal yang dapat dicapai jika mempertimbangkan kedua konsep tersebut pada tahap desain karena banyak keputusan penting pada proses desain dan berdampak pada tahapan selanjutnya . Penelitian sebelumnya hanya membahas faktor desain yang mempengaruhi constructability dan maintainability secara terpisah. Namun dalam kenyataan di
lapangan antara proses desain, constructability dan maintainability saling berkorelasi satu sama lain.
Penelitian ini bertujuan untuk menganalisis hubungan antara proses desain terhadap peningkatan constructability dan maintainability pada proyek
konstruksi. Variabel penelitian diperoleh dari studi literatur dan hasil survei kuisioner. Sistem dinamik digunakan untuk menggambarkan hubungan antar variabel dari proses desain yang mempengaruhi constructability dan
maintainability. Causal Loop Diagram (CLD) antara variabel yang terbentuk diverifikasi oleh expert. Nilai input untuk Stock Flow Diagram (SFD) didapatkan dari hasil kuisioner dengan responden yakni kepala perencana dan tenaga ahli perencana pada konsultan perencana yang tergabung dalam INKINDO Surabaya. Pada penelitian ini juga dilakukan wawancara dengan expert (pihak kontraktor
dan owner) yang digunakan untuk mendukung model awal yang telah terbentuk. Berdasarkan hasil skenario parameter, pengintegrasian proses desain dan constructability memiliki dampak yang paling signifikan terhadap maintainability dengan persentase perubahan atau peningkatannya 69.6% dibandingkan model
awal. Sementara itu hasil skenario struktur yang dilakukan terhadap maintainability, skenario yang memiliki dampak paling signifikan adalah dengan
menggabungkan ke enam faktor yang dapat meningkatkan maintainability. Dengan persentase perubahan atau peningkatan sebesar 54.17% dari model awal.===========================================================The number of problems that occur in the field during the construction phase caused by a mistake in the design phase. Problems that arise during the operational and maintenance phase also some arise due to errors during the design phase. Nevertheless currently most planner design firms have considered the concept of constructability and maintainability in their design process. This is due to their awareness of the optimal benefits that can be achieved when considering the two concepts at the design stage because many important decisions on the design process which have impact on the next phase. Prior research only deals with design factors that affect constructability and maintainability separately. But in reality in the construction project between the design process, constructability and maintainability are correlated to each other. This study aims to analyze the relationship between the design process to increase the constructability and maintainability of construction projects. The research variables were obtained from the literature study and the result of the questionnaire survey. System dynamic are used to describe relationships between variables of the design process that affect constructability and maintainability. Causal Loop Diagram (CLD) between the variables formed is verified by the expert. The input value for the Stock Flow Diagram (SFD) is obtained from the questionnaire with the respondents is the team leader and the planner expert on the consultant planner incorporated in INKINDO Surabaya. In this study also
conducted interviews with experts (the contractor and owner) used to support the initial model that has been formed. Based on the results of parameter scenarios, the integration of design and constructability processes has the most significant impact on maintainability with
a percentage change or an increase of 69.6% over the initial model. The result of the structure scenario being carried out on maintainability, the scenario that has
the most significant impact is by combining the six factors that can improve maintainability. With a percentage change or increase of 54.17% over the initial
model.
