OPTIMIZATION IN CRASHING PROJECT SCHEDULE WITH METHODS SELECTION
Abstrak

Crashing is a process of expediting project schedule by compressing the total project duration. It is helpful both in executing process, when managers want to anticipate the late project status, and in planning process, when the initial estimation does not meet objective time completion’s key stakeholder. Crashing the schedule plan would not only affect the duration of certain task but also the method applied to it indirectly. All methods that can complete the task could have different cost slope. In this paper we want to present a model to select the best method of crashed task to meet minimum cost. Binary Integer Nonlinear programming is used in this paper. The output of this model will determine task to crash, time to reduce, method, and the minimum cost of project.

 

Key words: Crashing, Cost Slope, Integer Nonlinear Programming, Optimization

ANALISIS RANCANGAN KERJA YANG ERGONOMIS UNTUK MENGURANGI KELELAHAN OTOT DENGAN MENGGUNAKAN METODE REBA PADA CV. SINAR PERSADA KARYATAMA
Abstrak

Manusia merupakan titik sentral dari ilmu ergonomi. Keterbatasan manusia menjadi pedoman dalam merancang suatu sistem kerja yang ergonomis. Fokus ergonomi melibatkan tiga komponen utama yaitu manusia, mesin/peralatan dan lingkungan yang saling berinteraksi antara satu dengan yang lainnya dan interaksi tersebut menghasilkan suatu sistem kerja yang tidak bisa dipisahkan. Penelitian ini dilakukan untuk mengurangi kelelahan dalam bekerja di CV. SINAR PERSADA KARYATAMA di stasiun pembuatan pola sepatu kulit. Pekerja tersebut bekerja secara membungkuk dan berjongkok dalam jangka waktu yang lama sehingga dapat menyebabkan kelelahan. Para pekerja pada umumnya kurang memperhatikan posisi tubuh dalam bekerja. Metode yang digunakan untuk menganalisis posisi tubuh adalah Rapid Entire Body Assesment (REBA). Penelitian ini dilakukan dengan wawancara kepada pihak terkait dan mengukur antropometri pekerja di stasiun pembuatan pola sepatu kulit untuk mendesain alat bantu kerja yang dibutuhkan. Nilai skor Rapid Entire Body Assesment (REBA) sebelum dianalisis pada stasiun pembuatan pola menghasilkan skor 12, berarti level risiko sangat tinggi dan membutuhkan perbaikan sekarang juga. Kemudian membuat alat bantu kerja berupa meja kerja dan kursi kerja serta merancang posisi pekerja yang ergonomis di stasiun pembuatan pola sepatu kulit, setelah itu menghitung menggunakan Rapid Entire Body Assesment (REBA) menghasilkan skor 3, berarti level resiko rendah dan tidak perlu perbaikan.

Kata Kunci : Ergonomi,  Antropometri, Rapid Entire Body Assesment (REBA)

A STUDY OF THE BASIC CONCEPT OF CRASHING CPM NETWORK USING DERIVATIVE MARGINAL COST IN LINEAR PROGRAMMING
Abstrak

For crashing a network, we have to find the best crash schedule for a CPM network by using linear programming. To illustrate this, we will use a simple project with seven activities: A, B, C, D, E, F, G and by using AOA system, we can find seven nodes: 1, 2, 3, 4, 5, 6, 7.

      The main purpose of this paper is to generate models that can solve time or cost limit problems. An optimum cost is needed when time limit is given while an optimum time is needed when cost limit is given. To solve this problem, we have to add two variables, Yj and Xi.  Yj = number of weeks we reduce the normal time of each j (activity) and Xi = the time event for each i (node) will occur. This paper deals with generation of linear programming model based on AOA CPM is shown in this paper.

      By using LINDO, we can find the optimal solution for the objective function, Yj values and the Xi values.

 

Key words: Project Management, CPM

Metropolitan Cities’s Waste Transportation Model
Abstrak

Metropolitan cities have the many problem to manage their waste, particularly in transportation management. One of critical factors to be considered at the time of transporting waste is traffic jam. It means using more resources and high cost. Through system engineering process approach as research methodology, the optimization model is developed using linear programming method to assign specific type of fleet in the right time and destination based on the best route to meet maximum saving of cost where traffic jam factor is inserted as an independent variable.


Key words: linear programming; optimization; transportation model; waste management; travelling salesman problem
