Abstract

Perusahaan Segi Tiga telah berdiri sejak tahun 1958 dalam memproduksi kecap. Sampai sejauh ini, kontrol persediaan Gula Aren sebagai bahan baku kecap di perusahaan tersebut masih menggunakan metode sederhana. Sebagai contoh, kegiatan pembelian bahan baku hanya dipertimbangkan dengan melihat sisa persediaan yang ada. Penggunaan cara tersebut membuat perusahaan mengalami kontrol persediaan yang kurang stabil dengan biaya yang tidak optimal. Tujuan penelitian ini adalah memperbaiki kontrol persediaan Gula Aren agar dapat meminimalkan kejadian overstock dan stock out, serta memperoleh biaya persediaan yang lebih ekonomis menggunakan pendekatan metode Economic Order Quantity dan Forecasting. Setelah dilakukan perhitungan, peramalan permintaan Gula Aren menggunakan metode Regresi Linear memperoleh hasil forecasting optimal sebesar 150.906 kg untuk satu tahun ke depan. Selanjutnya berdasarkan metode EOQ, kuantitas pemesanan optimal Gula Aren memperoleh hasil sebesar 24.782 kg dengan frekuensi pembelian optimal sebanyak 6 kali per tahun. Pembelian tersebut dilakukan apabila tingkat persediaan telah mencapai reorder point sebesar 1.986 kg. Untuk menghindari stock out, perusahaan perlu memiliki persediaan pengaman sebanyak 742 kg. Penerapan metode EOQ juga menghasilkan efisiensi total biaya persediaan sampai dengan 31% dengan penghematan hingga Rp250.826,09.

Abstract

PT ABC is an industry that produces hazardous and toxic waste. All waste generated is stored in temporary storage, but based on observations made, the existing temporary storage does not meet the standards set by the government. Therefore, a temporary storage area was redesigned at PT ABC in accordance with the standards set by the government. The objective of this study is to find a temporary storage place that complies with government regulations for PT ABC. The method used is to record the types, characteristics, and quantities produced by PT ABC, followed by existing observation, then proceed with the calculation of facility requirements according to SNI and individual calculations. A redesign is carried out by adjusting the calculation results, determining the required facilities, and making a design proposal. The results showed that PT ABC requires temporary storage of 6,1 m x 2,6 m x 4,4 m to accommodate all the waste generated for 3 months with the number of drums needed, namely 5 drums. The total ventilation needed is 6 pieces with a size of 0.5 m x 0.5 m. The required size of the spill container is 2.2 m x 1.2 m x 0.6 m, and it takes 3 lamps to illuminate the temporary storage.

Abstract

PT. XYZ is a company that produces motorcycle and car tires. This company has a fairly broad product market, so the products it manufactures have good product quality. In producing tires, one of the machines used in producing tires is an extrusion press machine. In carrying out its production, the extrusion press experiences downtime in the period August-December 2022, where the biggest downtime occurs in August, which has a downtime of 1890 minutes. After conducting an analysis using the Overall Equipment Effectiveness method to determine the level of effectiveness of the extrusion press machine, the OEE value calculation results from the August-December 2022 range are less than the international standard value of 85%. so we need an increase in the OEE value on the extrusion press machine. In increasing the OEE value, better engine maintenance is needed, so the Total Productive Maintenance (TPM) method is used as an effort to make engine maintenance even more effective.

Abstract

Scheduling is one of many project management activities that have a crucial role and support the success of a project. The existence of good scheduling is able to minimize delays in project completion and swelling of the budget costs incurred. This study aims to identify the optimal completion time, determine alternative acceleration, as well as the probability of completing the target duration for the construction project of Mosque and Orphan Dormitory Barokah Amanah Mustaqbal Foundation, Karawang. Based on analysis of CPM and PERT, critical path activities are A-C-D-E-F-G-H-K-M-N-O-P-Q-R-S-T with time completion faster than the target set for 90 days. In the CPM method, the project completion time takes 87 days. These results can also be accelerated by crashing programs on 7 alternative project activities, there is: M-P-O-E�Q-H-S. Crashing for a maximum of 8 days requires an increase in labor costs of 6,09% (Rp10.954.109) of the initial cost. The PERT method shows that a project duration of 86,7 days at probability level that can be completed in less than 90 days of 91,31%.
