Abstract

Kemajuan yang cepat di bidang industri adalah dikembangkannya mesin-mesin untuk kelancaran pekerjaan seperti halnya mesin-mesin yang sangat dibutuhkan dalam kelancaran suatu industri seperti alat press hidrolik multifungsi. Permasalahan pada bengkel bengkel sepeda motor yaitu alat untuk membuka suatu komponen dengan alat khusus di bengkel – bengkel yang tidak mempunyai alat khusus untuk membuka dan memasang komponen. Dibutuhkan Alat press hidrolik multifungsi kapasitas 1 ton untuk mempermudah atau mempercepat pekerjaan, dari latar belakang tersebut penulis ingin merancang sebuah alat press hidrolik dengan gaya maksimal 1 ton menggunakan dongkrak hidrolik, dengan dongkrak kapasitas 1 ton tersebut sudah dapat menghasilkan tekanan yang mampu memasang komponen seperti bearing dan mampu digunakan untuk mengepres shock absorber. Berhasilnya merancang dan membuat prototipe alat press hidrolik multifungsi kapasitas 1 ton, dengan pengujian rangka menggunakan Finite Elemen Methode (FEM) didapat hasil analisis tegangan (Von Misses) 232 mpa, perpindahan (Displacement) 1, regangan (Strain) 0 dan Faktor keamanan (savety of factor) 1.

Abstract

Construction waste consists of materials that are not desired directly or indirectly by the construction industry. This includes inert and non-biodegradable building materials such as sand, blocks, concrete, plaster, wood, iron, broken tiles, bricks, masonry, insulation, nails, electrical cables and reinforcement, as well as all residual materials (waste) originating from from the Construction Project Site.Data collection methods in this research were carried out by sending questionnaires via personal chat or via e-mail in the form of Google form to members of contractors, planning consultants, as well as construction supervision/management consultants and other parties operating in the territory of Indonesia, then the data The questionnaire was analyzed using Structural Equation Modeling (SEM) with the help of SPSS and AMOS programs.Factors that influence the reduction of construction waste include Contractual (X1) with an influence value of 0.154. Material Transportation (X2) with an influence value of 0.140. Material Storage (X4) with an influence value of 0.203. Use of Construction Materials (X6) with an influence value of 0.352. Professional Ethics (X7) with an influence value of 0.177. Managerial Action (X8) with an influence value of 0.329. Government Subsidies (X10) with an influence value of 0.337 and Government Regulatory Policy (X11) with an influence value of 0.294. Furthermore, factors that do not have a significant influence are Place Management and Planning (X3), Location Operations (X5) and Sustainability (X9). The most dominant factors influencing the reduction of construction waste include Use of Construction Materials (X6) with an influence value of 0.352 and government subsidies (X10) with an influence value of 0.337.
