Abstract

PT Sintas Kurama Perdana bergerak pada bidang produksi bahan Kimia. Bahan baku yang digunakan dalam pembuatan Asam Formiat terdiri dari bahan baku Katalis, Gas CO dan Methanol. Pada bahan baku tersebut dipilih salah satu bahan baku yang menjadi permasalahan yang sering terjadinya keterlambatan yang mengakibatkan terganggunya proses produksi. Pada data perusahaan kapasitas produksi bahan baku Katalis yang terpasang selama satu tahun sebelumnya sebesar 82855.83 Kg. Untuk memperkirakan kebutuhan bahan baku Katalis pada periode yang akan mendatang menggunakan metode peramalan Moving Average dan Exponential Smoothing. Hasil peramalan tersebut dipilih dari nilai Mean Absolute Percentage Error (MAPE) yang terkecil, yaitu dengan metode peramalan Moving Average dengan nilai n = 3 dengan MAPE 4,25%. Berdasarkan perhitungan diperoleh interval pemesanan bahan baku Katalis 7 hari dengan persediaan optimal 1.721,04 Kg, dari perhitungan metode probabilistik dapat dilihat dari biayapersediaan terbesar dengan metode Q dengan stock out yaitu sebesar Rp 5.604.240.766 dan yang terkecil adalahmetode P tanpa stock out yaitu sebesar Rp 5.476.204.602. Besarnya total biaya persediaan sangat dipengaruhi oleh besarnya rata-rata persediaan yang disimpan persiklus waktu dan biaya kekurangan akibat persediaan. Maka hasil metode yang digunakan dalam merencanakan persediaan pada bahan baku Katalis adalah metode P tanpa stok out dengan nilai terkecil yaitu sebesar Rp 5.476.204.602 per tahun.

Abstract

This study aims to improve the quality of the coffee roasting process at Small Coffee, an MSME located in Cikarang, by applying the TRIZ (Theory of Inventive Problem Solving) method and the Seven Tools of Quality Control. The roasting process often faces defects in coffee beans, such as unripe, broken, and burnt beans, which reduce product quality and customer satisfaction. To determine the root causes and influencing factors, the study utilized a fishbone diagram, affinity diagram, and scatter diagram. These tools helped identify critical process inefficiencies and quality issues. Subsequently, the TRIZ method was employed to propose innovative solutions that resolve contradictions in the roasting process without creating new problems. The proposed improvements are expected to enhance process efficiency, lower the defect rate, and ensure consistent product quality. Moreover, the implementation of these solutions provides tangible benefits for Small Coffee and serves as a model for other MSMEs in the coffee industry aiming to boost their competitiveness and long-term sustainability. This research highlights the synergy between systematic problem-solving tools and innovation frameworks in optimizing small-scale industrial processes.

Abstract

This research is conducted in SMEs engaged in the convection of children's and adult clothing. The problems in this study related to the optimization of the layout of the facility. The study aims to determine and compare the distance of moving materials before and after designing the layout of the facility and determining the layout of the facilities obtained by the From to Chart (FTC) method and the Layout Design Program Algorithm method. (ALDEP). The researchers took this problem to study because the production process flow from Adelian convection is still not optimal due to the large number of alternating material flows that cause swelling in material handling costs, resulting in less effective and efficient work. The results of the study using the FTC method obtained that the distance for the movement of goods for the initial layout from the process starting to storage is 624 m. The distance of the movement of goods for the proposal layout from the start of the process to storage is 437 m. Therefore, there is a reduction in the distance between facilities from the start of the process to the storage of goods by 187 m. The results of the study using the ALDEP method could cost material handling costs of 30.01% from the comparison between OMH/month in the initial layout, which was Rp.26. 947,778 with OMH/month from the proposal layout, which was Rp. 18,861,310.8, so there was a decrease in OMH/month by Rp. 8,086,467.2.
