Sebuah proyek pembangunan jembatan diturfukan dengan aktivitas-aktivitas dan wakhu setiap aktivitas sebagai berikut. Aktivitas & }(c) Waktu (minggu) & Aktivitas yang Mendahului A & 1 & - B & 2 & - C & 3 & B D & 6 & A E & 4 & A.C F & 4 & B G & 1 & E.F proyek tersebut digambarkan dalam diagram jaringan kerja adalah

### Diagram jaringan kerja proyek tersebut menunjukkan jalur kritis adalah A-C-E-G dengan durasi 9 minggu.

## Step 1: Understand the Project Schedule### The project schedule is given in a table format with activities, their durations, and preceding activities. This information is crucial to construct a network diagram that visually represents the sequence of activities and their dependencies.## Step 2: Identify Activities and Dependencies### From the table:- Activity A has no preceding activities and takes 1 week.- Activity B follows A and takes 2 weeks.- Activity C also follows A and takes 3 weeks.- Activity D follows B and takes 4 weeks.- Activity E follows C and takes 4 weeks.- Activity F follows both A and C and takes 3 weeks.- Activity G follows both E and F and takes 1 week.## Step 3: Construct the Network Diagram### To construct the network diagram:1. Start with Activity A since it has no predecessors.2. Draw arrows from A to B and A to C, indicating that B and C follow A.3. Draw an arrow from B to D, indicating that D follows B.4. Draw an arrow from C to E, indicating that E follows C.5. Draw arrows from A and C to F, indicating that F follows both A and C.6. Finally, draw arrows from E and F to G, indicating that G follows both E and F.## Step 4: Determine the Critical Path### The critical path is the longest path through the network diagram, determining the minimum project duration. Calculate the total time for each path:- Path A-B-D-G: weeks- Path A-C-E-G: weeks- Path A-C-F-G: weeks### The critical path is A-C-E-G with a duration of 9 weeks.
