The increasingly fierce industry competition causes each company needs strong supply chain activities as part of the company to be able to survive in an environment full of competition. In carrying out supply chain activities, it is certainly inseparable from supply chain risks that can disrupt supply chain activities. In supply chain risk it is important to know the key risks as the risks that trigger the other risks in the supply chain. This study aims to identify the relationship of risk and mitigation to reduce the causes of the risk. The interpretive structural modeling (ISM) approach is applied to solve problems related to risk linkages and produced key risks which are the risks that most influence the occurance of other risks. The key risks obtained are then processed using the house of risk (HOR) approach to determine the priority of risk mitigation actions. ISM result obtained four key risks, namely the risk element of inputting data error when entering the number of goods and spesifications, product spesification errors desired by the customer, frequent changes in customer design requests and revisions to the design drawings. Then the result of the HOR method obtained four recommended priority mitigation actions, namely updating information on a scheduled basis, conducting briefings every day before work, coordinating and reconfirming requests for product spesifications, and implementing more strigent worker selection procedures. The linkage of the causes of risk, the validation of the ISM model statistically and the weighting of the triggered criteria are several aspects that further research is needed.

PT. X is a company that produces plastic packaging for the pharmaceutical sector and already has regular customers from various pharmaceutical companies throughout Indonesia. However, currently, the maintenance of the Injection Blowing machine at PT X is not optimal, causing downtime to be very high which requires the machine to be turned off first and the expenditure for maintenance costs is relatively high. If this incident occurs continuously, it is necessary to make improvements to overcome these problems by improving the schedule for replacing components. For this reason, the method that can be used is preventive maintenance using a modularity design. The function of modularity design is to combine several components into new modules based on time and cause and effect. The homogeneity of the TTF (Time to Failure), Standard Deviation, and Nearest MTTF (Mean Time to Failure) data is the basis used in calculating time-based modularity designs, while for causality-based modularity designs the FTA (Fault Tree Analysis) approach is used. The purpose of the modularity design itself is to make it easier for the company that will make repairs, so it is not often necessary to stop the production machine while it is working. Furthermore, simulation modeling is carried out using Promodel to see the real conditions and current proposals. Through calculations in terms of costs generated for each method, it would be better if a preventive maintenance system was applied using a time-based modularity design based on the closest MTTF value (<7 days) which resulted in a total maintenance cost of Rp. 717,527,840.PT. X adalah sebuah perusahaan yang memproduksi kemasan plastik untuk bidang farmasi dan sudah memiliki konsumen tetap dari berbagai perusahaan farmasi di seluruh Indonesia. Namun saat ini, perawatan mesin Injection Blowing pada PT X belum optimal sehingga menyebabkan downtime menjadi sangat tinggi yang mengharuskan mesin dimatikan terlebih dahulu dan pengeluaran untuk biaya perawatan yang relatif tinggi. Jika kejadian ini terjadi terus-menerus, maka perlu adanya improvement untuk mengatasi masalah tersebut dengan cara memperbaiki jadwal penggantian komponennya. Metode yang dapat digunakan yaitu preventive maintenance dengan menggunakan modularity design. Fungsi dari modularity design adalah menggabungkan beberapa komponen menjadi modul baru yang didasarkan pada waktu dan sebab-akibat. Homogenitas data TTF (Time to Failure), Standar Deviasi, dan Nilai MTTF (Mean Time to Failure) Terdekat adalah dasar yang digunakan dalam perhitungan modularity design berbasis waktu, sedangkan untuk modularity design berbasis sebab-akibat menggunakan pendekatan FTA (Fault Tree Analysis). Tujuan dari modularity design sendiri adalah untuk memudahkan pihak perusahaan yang akan melakukan perbaikan, sehingga tidak sering untuk memberhentikan mesin produksi disaat sedang bekerja. Selanjutnya dilakukan pemodelan simulasi menggunakan ProModel untuk melihat kondisi nyata dan usulan saat ini. Melalui perhitungan yang dilihat dari segi biaya yang dihasilkan pada setiap metode, akan lebih baik apabila diterapkan sistem perawatan preventive maintenance dengan menggunakan modularity design berbasis waktu berdasarkan nilai MTTF terdekat (<7 hari) yang menghasilkan total biaya perawatan sebesar Rp 717.527.840,00.

Performance and productivity production line system are very influenced by facility layout planning. Facilities composition if appropriate with flow of materials between departments, it will sustain the continuity of the system. PT. X engaged in the field of printing. Composition of the current layout facilities on the Plant has not fully optimized well and indeed has a potential possibility to be developed further in the future. This statement is supported from the result of existing MHPS which gives Rp 6.560.374,50 for total cost of material handling and 136329 metres for total distance. As for the purposes of this research are: evaluating the performance of current facility layout, designing the layout of the facility with qualitative and quantitative methods, comparing the current with proposed improvement layouts, as well as create a picture the new layout facility. The process of designing proposed layouts is done by using qualitative methods (CORELAP, BLOCPLAN & CRAFT) and quantitative methods (ABSMODEL & CRAFT) that both of the algorithms need same inputs, which are: current facility layout and the flow of material. Based from the results of calculation proposed layouts, show that layout from qualitative methods (CORELAP) gives maximal reduction to the total cost of material handling so that the amounts will be decreased to Rp 6.100.133,55 (reducing 7,02% from total cost of current layout), and 117264 metres for total distance (reducing 13,985%.).
