The existence of a ship project carried out with a tender system by the LPSE allows all shipyard industries to bid on the project, this causes the chances of winning to become smaller, the determination of the tender price greatly determines the size of the profit that can be obtained and the percentage of the possibility of winning the project in a shipping industry. Therefore, the strategy of determining the bid price is very important. The statistical method used is multi discrete distribution, and multi normal distribution, while the bidding model uses Friedman (1956) and Ackoff & Sasieni (1968) models. The results obtained the best bid price strategy to win an auction or tender is the model that produces the lowest optimum mark-up, namely the Friedman model with multi normal distribution, while for Ackoff & Sasieni it produces a higher bid than the Friedman model except in certain company conditions.

The transportation industry is the main point of the distribution of goods and passengers. Data shows the number of shipwrecks is very high. The accident was caused by many factors, one of which was the tilting of the ship. The research starts from categorizing the causes of ship accidents through existing secondary data, FGD with expert judgments to find the root of the problem and also looking for what mitigations can be done so that similar incidents do not repeat. And the analysis is made in the Human Factors Analysis and Classification System (HFACS) method. The results of this study indicate that there are human factors in recurring events at all stages of HFACS such asunsafe acts, the preconditions for unsafe acts, unsafe supervision and organisational influences. For the stages of unsafe acts are Skill based Errors, decision errors, Perceptual Errors, and Exceptional. For the stage of the preconditions for unsafe acts are technological environment, physical environment, and adverse mental state; and for the stage of unsafe supervision is the lack of supervision; for organizational influences there are resource management and organizational climate.

For the running of a project, it is necessity to have project planning such as project schedule. PT Ometraco Arya Samanta is a company that engaged in steel structure. This company implement schedule planning based on tonnage. This method is considered suboptimal, since in its implementation has discrepancy of completion time between the schedule plan and the actual. To get an optimal schedule, it needs appropriate method. Construction project is a complex project and has uncertainty completion time. Project Evaluation and Review Technique (PERT) and Fuzzy Logic Application for Scheduling (FLASH) could be used for projects with uncertain completion time and more emphasis on time estimation than cost. PERT and FLASH are using three estimation time, then obtained probability percentage of completion time. Nevertheless, PERT is only consider the completion time by the critical path, while FLASH is able to determine project time by the entire project activities. Thereby, the methods used in this article is FLASH. The analysis results of this case study as follows: the interval completion time with FLASH in the amount of 106 days for optimistic time, 237 days for pessimistic time, and 169 days for most likely time. By the duration target of 179 days, it is obtained 85,29%. Dalam pengerjaan suatu proyek diperlukan perencanaan proyek berupa penjadwalan proyek. PT Ometraco Arya Samanta merupakan perusahaan konstruksi baja. Perusahaan ini memanfaatkan penjadwalan berdasarkan tonase proyek. Metode tersebut dirasa belum optimal, sebab dalam pelaksanaannya sering kali terjadi ketidaksesuaian waktu penyelesaian proyek antara rencana dengan aktualnya. Untuk mendapatkan penjadwalan yang optimal, diperlukan metode yang tepat. Proyek konstruksi merupakan proyek yang kompleks dan memiliki durasi penyelesaian yang bersifat tidak pasti. Project Evaluation and Review Technique (PERT) dan Fuzzy Logic Application for Scheduling (FLASH) dapat digunakan untuk proyek yang memiliki ketidakpastian waktu dan menekankan pada estimasi waktu daripada biaya. PERT dan FLASH menggunakan tiga estimasi waktu yang kemudian didapatkan persentase kemungkinan terselesaikannya proyek. Namun, PERT hanya memperhitungkan waktu penyelesaian proyek berdasarkan lintasan kritis, sedangkan FLASH dapat mempertimbangkan waktu proyek dari keseluruhan kegiatan proyek. Sehingga, metode yang digunakan di dalam artikel ini adalah FLASH. Hasil analisis dari penelitian ini didapatkan selang waktu penyelesaian proyek yaitu waktu paling cepat 106 hari, waktu paling lama 237 hari, dan waktu paling mungkin sebesar 169 hari. Dengan menggunakan waktu target 179 hari, didapatkan probabilitas sebesar 85,29% dari rentang waktu 169 hari hingga 237 hari.
