<![CDATA[This research reviews the planning and implementation of alternative fuel facilities at PT. Semen Gresik Rembang Factory, with a focus on storage and transportation efficiency of alternative fuels using the cycle time calculation method. This new facility is designed to increase the efficiency and smoothness of the cement production process, especially in the use of Alternative Fuel and Raw Material (AFR). By applying cycle time calculations, the time required to transport product waste from storage to the apron belt feeder with a dump truck can be determined more precisely. The results of the research show that the time required to use product waste in storage is 12 days, with a total cycle time from storage to apron of 16.68 minutes (0.3 hours) and requires 2 dump trucks to meet the needs of the apron belt feeder in one shift. The implementation of this method is expected to expedite the production process and increase operational efficiency at the Semen Gresik Plant Rembang Factory.]]>

<![CDATA[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.]]>

<![CDATA[Di PT. Indoprima Gemilang Plant-1 proses distribusi material masih dilakukan secara manual menggunakan kereta dorong. Banyaknya permintaan customer membuat peran kereta dorong kurang efektif karena membutuhkan waktu yang cukup lama dan melelahkan bagi operator. Salah satu teknologi yang dapat diterapkan untuk mengatasi permasalahan tersebut adalah sistem overhead conveyor. Supaya operator dapat memuat material ke hook yang terikat troli sebelum bergerak pada jalur rel, diperlukan struktur untuk proses vertical lifting material, yaitu proses memuat material ke hook yang terikat troli ditingkat yang lebih tinggi pada overhead conveyor. Penulis memutuskan untuk merancang struktur vertical lifting beserta komponen penunjangnya supaya memudahkan dalam proses memuat material ke hook. Penelitian ini menggunakan metode Ulrich dengan membuat 4 konsep desain, kemudian akan dipilih satu desain terbaik sesuai kriteria pemilihan. Perancangan dan analisis kekuatan struktur menggunakan software Autodesk Fusion 360. Analisis kekuatan struktur pada konsep desain terpilih diperoleh nilai minimum safety factor sebesar 3,928, nilai maksimum von misses stress sebesar 63,188 MPa pada titik target rangka panjang profil hoist dan nilai displacement maksimum sebesar 0,238 mm pada rel pengangkat beban. Hasil analisis structural buckling dengan batasan 1 kali beban pada konsep desain terpilih sebesar 350,589 kali beban. Total anggaran yang diperlukan untuk pembuatan struktur ini sebesar Rp10.557.260,-.]]>

<![CDATA[A large material removal rate and minimal surface rigidity are the desired objectives of this study with the right process parameters to obtain a large material response rate and a minimum surface hardness. The parameters used are spindle speed, feed rate and depth of cut. The experimental design is based on the response surface methodology of a box behnken design. The trials were randomized in three replications to produce a more optimal result. The results of the research showed that the influence of the parameter on the material removal rate is spindle speed with 0.442, feed rate with 0,000 and depth of cut with 0,000. parameter feed rate and deep of cut are stated to be significantly influenced. On the other hand, the influence of the parameter on the surface rigidity is that spindle speed with a of 0.017, feed rate with a of 0,000 and depth of cut has a of 0.074. Furthermore, the combination of the most optimal parameters for the material response variable removal rate and surface rigidity is the spindle speed of 2006 RPM, the feed rate of 252 mm/min and the depth of cut of 0.1965 mm.]]>

<![CDATA[The roller conveyor bearing housing is one of the injection molded products from a plastic manufacturing company in Sidoarjo. During the production process, there is an issue concerning the mismatch of the bearing housing diameter with the specified tolerance limits, which also slows down the production process. This study aims to find the optimal process parameter combination on the injection molding machine used for producing roller conveyor bearing housings. The response variable observed is the bearing housing diameter. The material used is polypropylene. The varied parameters include injection pressure, injection time, and cooling time. Data analysis utilizes the response surface method with a Box-Behnken experimental design comprising 15 experiments and 3 replications. From the experimental results, the optimal combination for both the housing diameter and cycle time responses includes an injection pressure of 60 bar, injection time of 6 seconds, and cooling time of 30 seconds. Injection pressure contributes 8.4%, injection time contributes 38.43%, and cooling time contributes 14.85% to the overall response]]>

<![CDATA[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.]]>

<![CDATA[PT. Ometraco Arya Samanta, a construction services company specializing in civil and steel construction, experienced problems with the CNC Punch machine in the Hall 3 fabrication area . The P 15 type FICEP CNC Punch machine stopped operating due to software and sensor damage. As a result, most of the workload is shifted to the Model TPPRD130 SCM CNC Punch & Drilling machine. These machines experience deterioration in performance and component damage due to increased workloads. To overcome this problem, the researcher calculates the availability rate, performance rate, and quality rate values to calculate the Overall Equipment Effectiveness (OEE), which is then multiplied by the utilization of the machine to get the Total Effective Equipment Performance (TEEP) value. The results of the analysis show that the TEEP of the SCM Model TPPRD130 CNC Punch & Drilling machine for the period of December 4, 2023 — December 16, 2023 is 16.56%. The magnitude of Total Effective Equipment Performance (TEEP) is still not in accordance with the TEEP global standard value of 80%. there is still a very wide difference of 63.44% between the global standard value of TEEP and the value of TEEP in the Company]]>
