Abstract

The word of construction is no stranger to rework. In the course of the implementation of construction, rework work may occur which can cause delays in the work process and swelling of the project cost budget. This can be influenced by several problems or factors that are often encountered during development work such as human resourse factors, documentation and disign, managerial with this can be from sevaral that have been mentioned that must be considered when planning construction development. In this study using descriptive research that directly takes data in the field by means of interviews, documentation, observation in order to be able to answer the research objectives properly and correctly according to the data obtained from the aforementioned data collection process. So that it can be seen the most frequently encountered rework jobs in the field. Based on the results of the study, it was shown that the dominant factor causing rework was managerial factor. The type of work that often experiences rework work is the finishing work of the second floor column casting. With the details of the causes of rework, the results obtained are design and documentation 22.5%, managerial 40.4%, and human resources 37.2%. The process of rework in the construction of the R S Roemani Semarang building can be concluded that there are several problems or identification of rework, namely porous columns, column slopes and column centring.

Abstract

In the planning of a project, there have to be a time schedule that can served as a guideline in the project, this shows that scheduling can influence the activity of a project. A good time schedule in a project can make project run effectively and efficiently, but in reality the actual work of a project did not always go as planned. In this case, the construction of library of UIN Sunan Ampel Surabaya.In the process of construction of library of UIN Sunan Ampel Surabaya, there is a delay that caused by a lot of factors, resulting in a delay of 49 days, the project initial duration is 154 days but the implementation duration is 203 days. Because of this, an analysis was carried out on this matter to determine what caused this lateness on project scheduleFrom the analysis that has been done the result is that the project lateness is caused in preparation work and the usage of work system with 3 shift but using the same man power. Factors of this lateness is caused by the owner, the conctractor, and weather disturbance.

Abstract. Analyzing the effect (K3) on the productivity of construction workers in wall and plaster work. The method used in this study is a descriptive method which aims to describe and describe the nature of something that was taking place at the time the research was conducted and to examine the causes of a particular symptom. The results of the analysis and discussion carried out that those who use incomplete K3 equipment do not affect work productivity time. From the results of this case study it can be concluded that the use of incomplete PPE equipment does not affect productivity effectiveness.Keywords: HSE, PPE, Productivity.

Abstract

Abstrak - Tanah mempunyai peranan yang sangat penting dalam suatu konstruksi, karena tanah berfungsi sebagai penopang beban-beban yang ada diatasnya. Metode yang digunakan dalam penelitian adalah pola pikir yang digunakan peneliti tentang bagaimana penelitian terus berjalan. Dari data pengujian sifat fisik dan sifat teknik yang telah diuji pada contoh tanah asli dengan penambahan pasir Pantai Guamanik Jepara, pengujian tanah pada Jalan Lingkar Kudus mempunyai tingkat dan karakteristik yang berbeda-beda. Berikut nilai persentase campuran pasir terbaik, pada uji berat jenis (gs) yaitu 5% dengan nilai 2,576, uji batas Atteberg pada indeks plastisitas mempunyai nilai paling rendah dengan penambahan 20%. pasir dengan nilai 0,57 maka uji proctormodified mempunyai nilai kandungan optimum tertinggi. dengan penambahan pasir 20% menggunakan 30 tumbukan dengan nilai 26,5, sedangkan nilai berat satuan tanah kering sebesar 1,399, pada uji geser langsung nilai kohesi tertinggi terjadi pada penambahan pasir 5% menggunakan 60 tumbukan dengan nilai sebesar 0,823, sedangkan nilai sudut geser dalam sebesar 23,97.Kata Kunci : Tanah, Proctor termodifikasi, Uji Geser langsung
