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.

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

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.

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.

Dalam teknologi penangkapan ikan yang berkembang saat ini masih menggunakan teknologi fishfinder yang berbasis akustik, selain mahal tidak semua ikan terdeteksi alat ini. Padahal Kementerian Kelautan dan Perikanan (KKP) saat ini telah menyediakan peta digital daerah persebaran ikan. Peta tersebut kita kenal dengan Peta Perkiraan Daerah Penangkapan Ikan (PPDPI). Untuk mengatasi permasalahan tersebut, sudah mulai dikembangkan teknologi yang lebih baik, yang dinamakan Portable Virtual Assistant untuk nelayan. Penelitian ini menfokuskan pada cara memperoleh data latitude dan longitude area berkumpulnya ikan yang berasal dari peta PPDPI. Terlebih dahulu gambar peta digital tersebut diolah dengan cara menentukan area fokus gambar peta yang akan diolah pada tahap berikutnya dengan menggunakan image processing. Area fokus gambar peta tersebut dirubah dari gambar berwarna menjadi hitam-putih. Dengan hitam-putih, gambar lebih mudah diolah lagi untuk ditemukan titik koordinat piksel gambar. Titik koordinat piksel tersebut dirubah ke latitude dan longitude dengan cara menggunakan rumus perbandingan latitude dan longitude peta dunia. Hasil penelitian ini mampu memberikan keakurasian hingga 1.791838% untuk latitude dan 1.11416% untuk longitude. AbstractExisting fishing technology still uses the acoustic-based fishfinder, besides expensive, itdoes not detect all types of fish. Whereas, Ministry of Marine Affairs and Fisheries Republic of Indonesia has provided digital map of fish distribution. The digital map is known as Peta Perkiraan Daerah Penangkapan Ikan (PPDPI). To tackle the problem, a better technolgy has just been developed , namely Portable Virtual Assistant for sailor. This study focuses on how to get latitude and longitude of fish group sourcing from the PPDPI map. Firstly the digital map is processed to determine the focus area of map image processed on the next steps by image processing. The focus area of map image is changed from color image to black and white image. By black and white image, it is easier to be processed again to be found coordinate-piksel of image. The coordinate-piksel was converted to latitude and longitude by comparing formula latitude and longitude of world map. The result is able to give accuracy up to 1.791838% for latitude and 1.11416% for longitude.

Many vocational schools have been bringing their educational practice closer to industry along with the concept of Teaching Factory (TEFA) to adjust the students’ skills as close as the industry demands. The implementation of TEFA based curriculum in one of vocational higher education in Surabaya for all subjects including English subject has been performed since 2019. In English classes, the Teaching Factory-Based Strategy covers two methods: product-based learning and flipped classroom. This research aims to explore the implementation of TEFA-based strategy and the two methods by revealing students' perceptions and responses on the strategy. This research is descriptive qualitative research in which data were obtained through questionnaires and interviews. The students observed were from 4 different study programs in this PPNS. The results of this study show positive perceptions of students toward TEFA – based strategy implemented in the classroom even though there are some obstacles faced by both students and lecturers. Hopefully this research can contribute practically to English teachers who are adopting TEFA in English language teaching.
