No full textThe Analysis Of Risk Management Implementation On Hospital Construction Project; Penulis: Frans Himawan Tanojo, Sutanto Hidayat, Subandiyah
No full textIn every construction job there must be a risk, the risk is a consequence of an
uncertain condition. In a construction work the uncertainty is substantial because it
can't be predicted exactly how much profit or loss will be obtained. Because of this,
there is a need for risk management analysis from early of a construction project to
reduce the risk and impact of possible risks. The results of this study by using the method
of principal component analysis based on the method of likelihood are aspect difficult
locations, the bureaucracy of the necessary permits, condition of the land acquisition is
difficult, the weather conditions, health and safety, payment is not on time, delays in
delivery of materials, location and site conditions are bad, demonstration/despoliation
on location of the project, policy of government's political, interest rates on bank loans
and the quality of materials that are less good; based on the impact are aspect of order
changes, human error, weather conditions, natural disasters, lack of timely payment,
health and safety, communication and coordination, equipment, material prices,
equipment is not feasible and the culture and customs. While the research results using
measurement scale AS / NZS according the likelihood of events resulted in three aspects
of risk is very high, 5 aspects of high risk and 4 aspects of intermediate risk, and based
on the impact occurs produces one aspect of risk is very high, four aspects of high risk
5 aspects medium risk and one low risk aspect

ANALISA KELAYAKAN INVESTASI AKIBAT KETERLAMBATAN DIMULAINYA PEMBANGUNAN PROYEK DI KOTA MALANG (STUDI KASUS MALANG TRADE CENTER BLIMBING)
No full textDalam pelaksanaan proyek, diperlukan pengendalian untuk menghindari terjadinya penyimpangan. Ada tiga hal yang perlu diperhatikan dalam pengendalian tersebut, yaitu: biaya, waktu dan mutu yang sesuai dengan rencana. Namun dalam kenyataannya, keterlambatan penyelesaian proyek sering terjadi karena salah satu dari tiga kompenen keberhasilan tidak terpenuhi. Tujuan penelitian ini adalah untuk mengetahui pengaruh keterlambatan dimulainya pembangunan ditinjau dari aspek finansial atau kelayakan investasi. Pengaruh tersebut didapat setalah melakukan analisa regresi dan least square terhadap perbandingan persentase kenaikan standar satuan harga dan nilai Inflasi. Hasilnya, kemudian digunakan untuk mencari nilai kembali modal ( Payback Period ) dan keuntungan bersih (NPV). Penelitian ini menghasilkan waktu kembali modal ( P a y b a c k P e rio d ) sebelum terjadi keterlambatan adalah tahun ke-11 masa investasi dengan NPV sebesar Rp.58.228.323.208,-. Setelah terjadi keterlambatan waktu kembali modal ( Payback Period ) menjadi tahun ke-13 masa investasi dengan NPV sebesar Rp.47.508.214.851,-. Selisih sebelum dan sesudah terjadi keterlambatan pembangunan untuk tahun pertama sebesar Rp. 12.357.823.217,- . Dan jika keterlambatan melebihi empat tahun, maka investasi sudah tidak layak lagi untuk dilakukan.

Optimizing agricultural land area to increase productivity for anticipating decreasing irrigation water supply
No full textIn order to maintain food security in Indonesia it is very necessary to organize
the provision of irrigation water as well as possible. Current surface water discharge
conditions have decreased compared to 10 years ago so that there really must be efficiency
and wise efforts in the provision of irrigation water in paddy fields. Many efforts to
increase the productivity of paddy fields and one of them is by optimizing the area of paddy
fields and regulating cropping patterns in the paddy fields. In the initial stage of this study
an analysis of the availability of surface water discharge was then analyzed for irrigation
water requirements that could be given to each paddy field in accordance with a
predetermined cropping pattern. Then a land area simulation is carried out to obtain the
most optimal land area. This simulation is carried out in the conditions of the wet season,
the normal season and the dry season. Simulations are carried out with various cropping
patterns including rice, secondary crops and sugar cane. Simulation results show that the
most optimal land area is in the wet season, then the normal season and the dry season
