BAB 5 KESIMPULAN DAN SARAN

5.1. KESIMPULAN. Tiga metoda durasi peramalan proyek dari earned value metrics yang diteliti dalam tesis ini telah memberikan gambaran yang memudahkan untuk menganalisa dan mengevaluasi durasi dan biaya selama proyek berlangsung. Analisa metoda EVM di awali dengan evaluasi dari metoda tradisional mengenai SV dan SPI dibanding dengan metode EVM baru yaitu Kemudian, dilanjutkan dengan analisa berbasis

SV(t) dan SPI(t).

formula Tiga metoda durasi

peramalan proyek yang telah diberikan oleh Anbari (1), Jacob (6) dan Lipke (4), ke dalam data proyek Major repair Tanki C dan D. Hasil analisa dan aplikasi dari earned value metrics telah memberikan gambaran berupa kesimpulan dan saran yang akan dijelaskan lebih lanjut pada paragraph di bawah.

Dari komputasi formula tiga metoda peramalan yang telah di gunakan pada bab sebelumnya dapat disimpulkan sebagai berikut: •

Planned value method (Anbari, 1), dalam evaluasi formula yang diberikan, pada keadaaan proyek yang mengalami keterlambatan dalam penyelesaian dan biaya yang melebihi dari rencana semula, mengindikasikan kesamaan hasil perhitungan dalam memonitor proyek pada paruh awal hingga pertengahan proyek dengan metoda dari dalam earned duration method (Jacob, 6), maupun dalam earned schedule method (Lipke, 4). Sedangkan pada penggunaan formula proyek yang selesai tepat waktu dan biaya dibawah rencana awal, hasil komputasi antara ketiga metoda tersebut menghasilkan kesamaan nilai hasil keluaran.

Formula Anbari hanya memberikan indikator penyelesaian atau Estimated at Completion, sedangkan formula indikator dugaan performansi dalam menyelesaikan pekerjaan atau TCSPI dan TCSPI(t) tidak dimiliki.



Earned duration method (Jacob, 6) dalam aplikasinya pada tesis ini, memberikan hasil keluaran yang sama dengan metoda yang diberikan oleh Anbari maupun oleh Lipke pada awal hingga pertengahan proyek. Kemudian menjadi tidak sesuai dengan kondisi sesungguhnya pada pertengahan hingga selesainya proyek. Kondisi ini terjadi pada keadaan dimana durasi proyek dan biaya melebihi dari rencana awal. Seperti yang dimiliki oleh Anbari, metoda Jacob akan menghasilkan nilai yang sama disaat proyek selesai tepat waktu. Jacob memberikan tambahan metoda berupa formula analisis indikator dugaan. Formula ini sangat berguna dalam menjabarkan dalam bentuk grafis bahwa sebuah proyek memiliki nilai performansi durasi yang baik dalam menyelesaikan proyek atau dikenal dengan TCSPI (to complete schedule performance index).



Earned Schedule (Lipke, 4) adalah contoh ideal formula EVM dalam memonitor sebuah real data project ke dalam sebuah kurva grafis kemajuan proyek. Metoda Lipke dapat menterjemahkan kondisi sebenarnya sejak awal hingga selesainya sebuah proyek. Keadaan ini tentu saja memberikan respon yang positif baik dari tim proyek, managemen proyek maupun stakeholders agar dapat dengan cepat memahami dan melakukan revisi pekerjaan yang diperlukan setelah melihat situasi sebenarnya dari proyek yang sedang berjalan tersebut.

Dari penjelasan di atas, kegunaan planned value method, earned duration method, earned schedule method adalah tergantung dari keperluan dan kemampuan dari manajer proyek dalam menterjemahkan kemungkinan kesamaan hasil yang diberikan dalam monitor proyek saat awal hingga pertengahan proyek, kemudian untuk pekerjaan yang tersisa yaitu antara pertengahan hingga akhir Page 52 of 84

proyek. Metoda peramalan earned schedule dapat dijadikan fokus analisis dalam memonitor proyek hingga final.

Dengan penggunaan earned schedule sebagai basis monitor dalam analisa durasi proyek Major repair, penggunaan metoda planned value maupun earned duration tetap dapat digunakan sebagai pembanding analisa, sehingga efektifitas evaluasi dari durasi proyek akan tetap terjaga.

“The early signal” dari metoda yang telah digunakan diatas, dapat pula di gunakan dalam menganalisa sub grup dari WBS dalam hubungannya dengan durasi proyek, Kemudian mengkoreksi aktifitas-aktifitas yang mengalami kesalahan, terutama pada tugas yang masuk koridor critical path. Terbukti pada hasil peramalan dua buah proyek Major repair tank yang sudah dikerjakan dengan menggunakan earned value metrics, terlihat bahwa konsep early warning dapat gambarkan dengan mudah dalam bentuk kurva grafis sederhana.

5.2. SARAN Karena semakin kompleksnya permasalahan mengenai target penyelesaian pada setiap proyek, metoda EVM dapat dijadikan sebagai parameter praktis dalam melihat dan menganalisa kemungkinan-kemungkinan selama proyek berjalan hingga selesai. Metoda EVM dalam konsep Early warning telah memberikan sumbangsih yang bernilai dalam mendeskripsikan kondisi proyek yang sebenarnya. Dengan rencana perbaikan Major repair lanjutan pada lokasi CICO Kalimantan timur lainnya, di harapkan metoda EVM ini dapat digunakan sebagai salah satu parameter sistem manajemen yang berguna secara efektif dalam memonitor dan menganalisa kelangsungan dari sebuah proyek yang sesungguhnya. Corrective action akan selalu terjadi selama proyek berjalan, tetapi kapan saat yang tepat

Page 53 of 84

untuk melakukan corrective action adalah kendala yang sering kali terjadi dan terlambat untuk dilakukan. Metoda EVM dapat dengan mudah menjembatani antara waktu kritis dari sebuah proyek dan saat dimana corrective action harus segera dilakukan. terintegrasi antara tim proyek, eksekutif dan project stakeholders.
