Abstract By following WHO guidelines, the minimum blood availability is 2% of the population. The total population of Indonesia in 2016 is 261.115.456, so ideally it takes 5.222.309 blood bags. In 2013-2015 for 36 months, there were 26 overstock events and 10 stockout events. The data shows that the frequency of over-supply is more frequent than over-demand. The high overstock has an impact on the high costs incurred by the City of Bandung PMI, if there is overstock there are two costs to be incurred, namely the cost of storing if the blood is still in good use and the cost of overstock if the blood is more than the expiration date. The purpose of this study was to determine the optimal value of inventory levels to reduce wastage of blood culling due to overstock occurring at PMI Bandung. The research method uses a quantitative approach to the optimization model of inventory policy, namely Uncertainty EOQ. The optimal amount of supplies that must be provided is at intervals of 8,705 - 9,375 blood bags with a large safety stock 403 blood bags and the ordering point is at the level of supplies of 5.706 blood bags. This proposal can provide a total inventory cost savings of Rp6.622.659.034/year. Keywords: Blood, Overstock, EOQ, Uncertainty Abstrak Sesuai dengan panduan WHO, ketersediaan darah minimal adalah 2% dari jumlah penduduk. Jumlah penduduk Indonesia tahun 2016 adalah 261.115.456 jiwa, maka idealnya dibutuhkan 5.222.309 kantong darah. Tahun 2013-2015 selama 36 bulan, terdapat 26 kejadian overstock dan 10 kejadian stoc-kout. Data tersebut menunjukan bahwa frekuensi over-supply lebih sering dibandingkan over-demand. Tingginya overstock berdampak pada tingginya biaya yang dikeluarkan oleh PMI Kota Bandung, jika terjadi overstock ada dua biaya yang harus dikeluarkan, yaitu biaya simpan jika darah masih dalam masa baik digunakan dan biaya overstock jika darah sudah lebih dari tanggal kadaluarsa. Tujuan penelitian ini adalah mengetahui nilai tingkat persediaan yang optimal untuk mengurangi pemborosan pemusnahan darah akibat overstock yang terjadi di PMI Kota Bandung. Metode penelitian menggunakan pendekatan kuantitatif model optimasi pada kebijakan inventori yaitu EOQ Tak Tentu Berisiko Terkendali. Jumlah persediaan optimal yang harus disediakan berada di interval 8.705 – 9.375 kantong darah dengan besar safety stock 403 kantong darah dan titik pemesanan berada di tingkat persediaan 5.706 kantong darah. Usulan ini dapat memberikan penghematan total biaya persediaan sebesar Rp6.622.659.034/tahun. Kata kunci: Darah, Overstock, EOQ, Tak Tentu

Sugarcane is one of the plantation crops which is used as raw material for making sugar. The efficiency of inventory is very important for a sugar factory. The purpose of this study is to determine the order level, order frequency, the amount of safety stock (Safety Stock), re-order points (sugarcane raw material) which is economical and to know the total inventory cost (Total Inventory Cost) of sugarcane raw material economical in PG X. The method of determining the area of ​​this research was carried out intentionally (purposive). The research method uses the descriptive-analytic method. The analytical tool used is Economic Order Quantity (EOQ), Re-Order Points (ROP), Safety Stock (SS), and Total Inventory Cost (TIC). The results of the 2018 and 2019 EOQ calculations show it is not yet economical. The 2018 EOQ calculation was 1.688,79 tons greater than the number of orders made by PG X by 1.483,9 tons and the 2019 EOQ calculation was 3.074 tons greater than the number of bookings made by PG X by 976,6 tons. The value of the safety stock in 2018 amounted to 1.483,9 tons and in 2019 it was 976,6 tons. The value of ROP in the supply of raw sugar cane in 2018 was 2.967,8 tons and in 2019 it was 1.953,2 tons. The 2018 TIC value is Rp. 139.031.870 smaller than the cost of inventory incurred by the company of Rp. 158.302.102 and the 2019 TIC value of Rp. 208.014.632 less than the cost of inventory incurred by the company of Rp. 654.250.185. The results of the last two years calculations indicate the inefficiency of orders made because it causes the frequency of orders is greater and the inventory costs incurred by PG X are higher., so with economic calculations, the order frequency will be less and the total cost of inventory will be lower.

Inventory control can be done by reducing the cost of inventory and the number of ordering frequencies economically. PT Tanjung Globalindo Utama or Toko TODA is an oil and accessory retail store that provides various oil needs. Some of the problems are late delivery of goods from suppliers, so that for several days the company cannot operate optimally. On the other hand, the company has also experienced an excess inventory of merchandise, so the company wastes due to excess inventory of merchandise which in turn increases inventory costs. The Community Service Team (PKM) provides a solution for TODA Stores in overcoming their problems by providing training in inventory management in the Economic Order Quantity (EOQ) method. PKM activities were carried out on May 22, 2020. Participation of partners in the PKM program is to participate in discussions, provide historical data, and convey targets. The output is that the TODA Shop can determine the amount and schedule for the procurement of merchandise economically. The result is that Toko Toda begins to understand the importance of controlling inventory so that inventory costs are not too high. Proposed procedures for purchasing merchandise inventory were received and started to be carried out with monitoring from the relevant PKM Team. Based on the calculation simulation results and discussion shows that the use of the EOQ method in controlling merchandise inventory at Toda Stores is very efficient, seen from the amount of cost savings obtained if the total inventory cost calculation uses the EOQ methodABSTRAK:Pengendalian persediaan dapat dilakukan dengan menekan biaya persediaan dan jumlah frekwensi pemesanan secara ekonomis. PT Tanjung Globalindo Utama atau Toko TODA adalah Toko retail oli dan aksesori yang menyediakan berbagai kebutuhan oli. Beberapa permasalahan yang sering dialami adalah keterlambatan pengiriman barang dari supplier, sehingga selama beberapa hari perusahaan tidak dapat beroperasi maksimal. Disisi lain perusahaan juga pernah mengalami kelebihan persediaan barang dagang, sehingga perusahaan melakukan pemborosan akibat kelebihan persediaan barang dagang yang pada akhirnya meningkatkan biaya persediaan. Tim Pengabdian Kepada Masyarakat (PKM) memberikan solusi untuk Toko TODA dalam mengatasi permasalahannya dengan memberikan pelatihan tata kelola persediaan metode Economic Order Quantity (EOQ). Kegiatan PKM telah dilaksanakan pada tanggal 22 Mei 2020.
