Abstract

Abstract - One of the manufacturing companies in Indonesia is developing a modern rice mill plant (MRMP) project in Jember. The infrastructure development of the project requires some planning, one of which is a good layout design. The layout design in the project has problems including the arrangement of machinery that is not in accordance with the production flow, the utilization of the available area is not maximized, and does not pay attention to the close relationship between facilities so that it will cause back tracking and excessive movement that will harm the company. Solving these problems can be done by designing a new facility layout using the Systematic Layout Planning (SLP) method. The results of the research using this method were obtained as many as 4 layout proposals, then one layout proposal was chosen, namely layout 4. The selected layout proposal has a difference in OMH value and total material handling mileage with the highest initial layout and can increase efficiency in material handling by 28.88 % on total material handling mileage and 37.47% efficiency on material handling costs per day.

Abstract

According to the minister of industry, despite being under pressure due to the Covid-19 pandemic, a number of industrial sub-sectors grew very high in 2021. With this increase, the company finally carried out an evaluation. PT.AAM is still not optimal in meeting the supply of raw materials for fire door production. The main cause that often occurs is the large number of purchases of raw, causing hoarding which can affect the total cost of raw material inventory. Researchers will analyze these problems using the Economic Order Quantity method. The results using EOQ can result in inventory costs being decreased by an average of Rp.1.296.922. with less ordering frequency and optimum cycle. The reorder has been determined by the number of calculations from the reorder point.

Abstract

The shipbuilding industry is a fabrication industry in the ship sector that involves the use of materials and manufacturing processes.. When a shipbuilding project is finished later than expected, the shipyard is required under the contract agreement to pay a penalty. PT Batam Expresindo Shipyard must pay a penalty equal to 1 mill of the contract value every day because the implementation is delayed, as was the case with the 17M Aluminum Fisheries Supervisory Shipbuilding project.One solution that can be done is by crashing the project on the work that is on the critical path. This research uses Critical Path Method (CPM) and Time Cost Trade Off method. The results of the analysis found that the optimal time and cost with an alternative addition of labor and additional working hours of 5 hours from normal working hours with a productivity of 80%. The resulting crashing project duration is 30 days faster than the actual duration, from a total project duration of 222 days to 192 days with an additional crashing project cost of Rp. 76. 719,846.

Abstract

Repair and maintenance activities aim to increase the functional capability of a system or tool used in production. At PT. Lintech Duta Pratama (PT. LDP), overhead crane is used as a means of moving materials and finished goods. This tool operates to transport materials and finished goods continuously for ± 7 hours per day for 5 working days a week. However, maintenance actions have not been carried out optimally due to a lack of manpower/workers. Thus resulting in delays in the implementation of maintenance activities and affect the completion of production. Against this background, failure identification was carried out using the Failure Mode and Effect Analysis (FMEA) method on the 12.5T overhead crane. With this method the results obtained by filling in the FMEA Worksheet showed that there were 13 components that had the highest risk level value, with 26 failure modes from whole component. The highest RPN value is for the MCB/main power supply component with a value of 209, while the lowest is for the hoisting hook component with a value of 7. So that this component can be considered by the maintenance team and related parties in the company when carrying out maintenance activities on the overhead crane equipment.

Abstract

One important construction that needs to be considered on the ship is the stern ramp door. This is because the stern ramp door construction will receive both static loads during its operation. The strength of a structure makes a very important contribution to the overall safety of the system. This study aims to analyze the construction of the stern ramp door to be at a safe limit when used. The analysis method used is the finite element approach (FEM). The output of the structural analysis with the FEM method is to solve the deflection and stress in a structure that receives a certain load under appropriate boundary conditions. This study resulted in a maximum stress that occurred at a plate thickness of 6 mm of 75.67 N / mm² or 75.67 mPa this voltage also meets the provisions of the BKI Strength criteria because it does not exceed the voltage of 98.40 N / mm² or 98.40 Mpa. The deflection that occurs at a plate thickness of 6 mm, the front wheel loading has a deflection of 17.6 mm so that the rear wheel loading has a higher deflection than the front wheel by 35.2 mm. Safety factor at 6 mm thick gets a safety factor of 0.76

Abstract

Proyek Docking Repair KT. Anggada XV mengalami keterlambatan, sehingga kapal terhambat tidak bisa berlayar sesuai dengan yang sudah dijadwalkan. Maka waktu menjadi variabel penting yang digunakan sebagai parameter utama dalam penyelesaian proyek Docking Repair. Tujuan dari Tugas Akhir ini yaitu melakukan analisis penjadwalan terhadap keterlambatan proyek Docking Repair KT. Anggada XV dengan status intermediate survey. Dengan demikian diperlukan upaya penjadwalan durasi proyek untuk mengembalikan tingkat kemajuan proyek ke rencana awal. Perencanaan penjadwalan proyek dilakukan dengan menggunakan metode PERT (Project Evaluation Review Technique) dan FLASH (Fuzzy Logic Application for Schedulling). Proyek Docking Repair KT. Anggada memiliki 8 pekerjaan yang berada pada jalur kritis proyek yaitu tes ketebalan plat (UT), penggantian plat, pemeliharaan jangkar, rantai, dan windlash, bongkar pasang propeller, polish propeller, tambal bolangbaling, balansir propeller, dan test keretakan propeller. Hasil dari perhitungan penjadwalan proyek menggunakan metode PERT didapatkan nilai rata-rata penyelesaian proyek selama 25.165 hari dengan nilai probabilitas 93,57%, sedangkan metode FLASH didapatkan nilai durasi minimal selama 25.25 hari dan durasi maksimal selama 26.45 hari. Berdasarkan perhitungan, waktu penyelesaian proyek dengan metode FLASH lebih baik digunakan dikarenakan hasil dari perhitungannya berupa interval waktu Dmin dan Dmax berbeda dengan metode PERT yang hasil perhitungannya hanya didapatkan waktu penyelesaian yang sudah pasti.

Abstract

Projects are a series of production processes that produce certain outputs within a specified time period. Compactor Roller Compact Mould implemented by one of the manufacturing companies in Sidoarjo has experienced delays from the deadline that has been set. This delay is caused by ineffective planning and scheduling, which results in the completion of other projects being delayed. The project consists of many overlapping sub-activities. Therefore, this research was conducted to reschedule each overlapping activity using the Precedence Diagram Method (PDM). The results showed that projects with many activities can be decomposed using network planning to plan each activity in the project. Thus, in future research, this network planning can be used to identify which set of activities takes the longest time and can be analyzed further to speed up the processing time of sub-activity tips on the project.
