Abstract

Kontrak Berbasis Kinerja (KBK) merupakan kontrak terintegrasi sebagai salah satu upaya pemerintah agar jalan raya selalu dalam kondisi mantap. Sebelumnya, pemeliharaan jalan dilakukan dengan kontrak konvensional dimana perencana, pelaksana pekerjaan konstruksi dan masa layanan pemeliharaan dilakukan oleh penyedia jasa yang berbeda. Sedangkan kontrak berbasis kinerja ini menyerahkan semua tanggung jawab tersebut pada satu penyedia jasa (kontraktor) dan dibayar secara lump sum sesuai kinerja yang dihasilkan. KBK mendorong penyedia jasa untuk menyediakan pekerjaan bermutu jika tidak ingin mengalami kerugian lebih besar pada masa layanan pemeliharaan. KBK telah digunakan di negara maju dan negara berkembang serta berhasil memberi manfaat bagi otoritas jalan berupa penghematan biaya pemeliharaan dan peningkatan kondisi aset jalan yang dikontrakkan. Pada dasarnya kontrak berbasis kinerja merupakan usaha penempatan risiko kepada pihak penyebab risiko. Pada kontrak konvensional, risiko tersebut menjadi beban pihak pemerintah. Penelitian ini bertujuan untuk identifikasi risiko-risiko pada tahap persiapan kontrak berbasis kinerja yaitu tahap prebidding, bidding serta tahap perencanaan konstruksi, tahap pelaksanaan konstruksi dan masa layanan pemeliharaan. Tahap prebidding dan bidding merupakan lingkup pekerjaan pemilik proyek (owner) sedangkan tahap selanjutnya yaitu tahap perencanaan, pelaksanaan dan masa layanan pemeliharaan merupakan lingkup pekerjaan penyedia jasa

Abstract

Investasi perhotelan di Kabupaten Pati semakin berkembang, hal ini ditandai dengan berdirinya hotel berbintang tiga The Safin Hotel dan hotel baru lainnya. Akibat adanya perkembangan  tersebut, maka perlu dilakukan evaluasi kelayakan investasi pada The Safin Hotel. Evaluasi ini bertujuan untuk mengetahui apakah hasil dari perencanaan awal masih relevan dengan kondisi saat ini berdasarkan data terbaru. Makalah ini hanya meninjau aspek finansial dengan menggunakan metode Net Present Value (NPV) dan Internal Rate of Return (IRR). Kemudian dilakukan analisis sensitivitas tingkat penghunian kamar, tarif sewa kamar, dan biaya operasional & pemeliharaan terhadap nilai NPV.Dari hasil analisis didapatkan bahwa investasi The Safin Hotel adalah sebesar Rp 79.699.382.000 dengan asumsi MARR 11,48% didapatkan nilai NPV sebesar negatif Rp  3.397.498.861 (NPV < 0) dan hasil analisis Internal Rate of Return (IRR) sebesar 11,40%, kurang dari arus pengembalian yang diinginkan sebesar 11,48%. Maka The Safin Hotel dikatakan tidak layak dari segi finansial. Sedangkan hasil analisis sensitivitas antara variabel tingkat penghunian kamar, tarif sewa kamar, dan biaya operasional dan pemeliharaan terhadap nilai NPV didapat bahwa The Safin Hotel akan menjadi layak apabila tingkat penghunian kamar lebih dari 52,07%, atau tarif sewa kamar dinaikkan minimal 3,33%, atau biaya operasional dan pemeliharaan diturunkan 7,69%.
