Abstract

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.

Abstract

Analyzing the material composition of iron sand from Cilacap beach and iron sand from Taluk Kuantan beach in Riau. In this research, the synthesis of barium M-Hexaferrite is made from iron sand from Cilacap beach and iron sand from Taluk Kuantan beach, Riau. In the research method, the test was carried out using composition analysis with FTIR test. The characteristics of the test using the FTIR test that the iron sand of the Cilacap beach has an Fe content of 86.53% and does not carry out refining. while the iron sand of Taluk Kuantan beach has an Fe content of 82.86% and is not purified. Based on the wave number value, BAM doped with Cu has the best wave number value and the highest transmittance value is around 92% at wavelengths from 1467.03 to 669.56 cm−1.

Abstract

Perkembangan teknologi dalam bidang pendidikan terus mengalami perubahan signifikan setiap tahunnya, salah satu contoh adalah penerapan Massive Open Online Courses (MOOCs). Namun setelah pandemi COVID-19, transisi pembelajaran dari daring ke luring memberi tantangan dalam pengembangan pendidikan termasuk platform MOOCs perlu diteliti lebih lanjut. Penelitian ini bertujuan untuk mengukur tingkat keberlanjutan mahasiswa dalam menggunakan MOOCs melalui platform LMS yang diterapkan di Politeknik Perkapalan Negeri Surabaya. Studi ini menggunakan pendekatan kuantitatif dengan desain longitudinal, di mana data dikumpulkan melalui kuesioner yang diisi oleh 178 responden. Analisis data dilakukan dengan metode deskriptif, termasuk perhitungan rata-rata, median, modus, serta nilai maksimum dan minimum. Hasil penelitian menunjukkan mayoritas responden memiliki pandangan positif terhadap MOOCs; terutama dalam aspek kegunaan, “Aspek Individual-Technology Fit, Aspek Task-Technology Fit dan Aspek Social Motivations (motivasi sosial)”.

Abstract

The increasing number of dock needs is a business opportunity that is being utilized by a company engaged in the Modular Float System or floating cubes in East Java. The company uses a Modular Float System or floating cubes made from High Density Polyethylene (HDPE) to be structured into an environmentally friendly floating dock. However, the floating dock business based on the Modular Float System or floating cubes is still experiencing several obstacles. The constraints experienced can cause losses for the company. This research uses the ISO 31000:2018 framework to identify potential risks and determine priority risks. Then design a strategy to mitigate the risk based on the root causes of the risk. The results of the analysis using the ISO 31000: 2018 framework found 33 sub risks from 4 risk categories. Based on the Risk Assessment, there are 4 priority sub-risks. The priority sub risks from external risk category are analyzed in order to get the root causes of their occurrence to obtain the right risk management strategy for the floating dock project.

Abstract

Freight forwarding is a service company that aims to represent the interests of the owner of the goods in taking care of all the activities required during delivery to receipt of goods. The subject in this study is a freight forwarding company in Surabaya. The increasing competition among companies engaged in logistics encourages each company to measure the level of customer satisfaction so as to find out how satisfied customers are with the company's services. The research method used is the method of Service Quality (Servqual) and the results in the study obtained all attributes of negative value with the highest value of each dimension is on the Tangibles dimension with attributes of sophistication owned physical facilities and facilities and infrastructure in serving consumers by -0.39, Reliability dimension with attributes of accuracy of handling or administrating records/documents by - 0.74, Responsive dimension with attributes, assurance dimension with employee attributes has a good ability in providing services of -0.67, and Emphaty dimension with employee willingness attributes in informing the existence/constraints of - 0.39. From the analysis it can be concluded that customers are still not satisfied with the company's service so the company must be quick to fix the shortcomings.

Abstract

One of the shipyards in Madura is currently executing the tug boat Transko Gagak repair project. This project has experienced an 11-day delay due to several obstacles, including a leakage issue with the floating dock pump, resulting in a failed docking attempt, as well as delays in the procurement process. The purpose of this study is to analyze the performance of the ship repair project in terms of cost and time. The methods employed for analyzing thisproject's performance are Earned Value Analysis (EVA). The analysis results on the 22nd day indicate that the project's schedule performance is 0.59 (SPI < 1), indicating a delay of 38.93% from the initial planned project completion of 100%, with actual completion of 61.07% of the work. In terms of cost performance, the value is 1.47 (CPI > 1), signifying thatthe expenditures have been lower than the initial budget plan. This reduction is due to the elimination of certain work items during the project execution.

Abstract

Port operations using conventional RTG (Rubber Tyred Gantry) results in an increased operational cost burden as maintenance costs and diesel fuel prices continue to increase every year. Therefore, a power source change was made by using electrical energy through container loading and unloading equipment installation work. However, the implementation of implementation of the work raises various possibilities and risk impacts that need to be anticipated. One of them is the risk that can hinder the smooth work and cause significant delays. This research aims to determine the potential risks of work that may occur. The analysis uses the Failure Mode and Effect Analysis (FMEA) method. The results show that there are 20 potential risks with 6 of them being prioritized risks.
