Abstract
PT Wanindo Jaya Plastik merupakan perusahaan yang bergerak dalam produksi kantong sampah plastik dan plastik cor. Dalam bisnis manufaktur plastik terjadi persaingan yang cukup ketat, sehingga PT Wanindo Jaya Plastik perlu untuk terus berinovasi dalam menciptakan produk yang baik. Penelitian menggunakan metode Kaizen Costing dalam berinovasi dengan usaha mengurangi biaya yang dikeluarkan pada proses produksinya tanpa harus mengorbankan kualitas produk, sehingga daya saing di pasar dapat dipertahankan. Penelitian diawali dengan melakukan wawancara, observasi, dan dokumentasi pada PT Wanindo Jaya Plastik, yang terdapat data aktivitas produksi termasuk proses produksi, waktu proses produksi, sumber daya, dan biaya yang digunakan. Kemudian, pada penelitian dilakukan analisis terhadap setiap komponen biaya dan pengelolaan sumber daya yang lebih efektif dengan menggunakan konsep Kaizen Costing. Pengolahan data dilakukan dengan cara melakukan perhitungan efisiensi biaya pada masing-masing aktivitas yang memerlukan biaya sebelum dan sesudah implementasi. Implementasi metode Kaizen Costing pada penelitian ini membuktikan bahwa metode ini dapat mengidentifikasi dan mengurangi aktivitas yang tidak bernilai tambah pada proses produksi perusahaan dan tetap menjaga kualitas produk. Hasil penelitian menunjukkan bahwa pada tahap do dapat terjadi penurunan keseluruhan biaya produksi sebesar Rp 17.405.876,36 untuk masing-masing produk plastik cor sebesar Rp 5.505.173,55 per bulan dan untuk produk kantong sampah plastik sebesar Rp 11.900.702,81 per bulan.

PT Wanindo Jaya Plastik is a company engaged in the production of plastic garbage bags and cast plastic. In the plastic manufacturing business there is quite intense competition, so PT Wanindo Jaya Plastik needs to continue to innovate in creating good products. The research uses the Kaizen Costing method in innovating in an effort to reduce costs incurred in the production process without having to sacrifice product quality, so that competitiveness in the market can be maintained. The research begins with conducting interviews, observations, and documentation at PT Wanindo Jaya Plastik, which contains data on production activities including the production process, production process time, resources, and costs used. Then, the research analyzed each cost component and managed resources more effectively using the Kaizen Costing concept. Data processing is done by calculating cost efficiency in each activity that requires costs before and after implementation. The implementation of the Kaizen Costing method in this study proves that this method can identify and reduce non-value-added activities in the company's production process and still maintain product quality. The results showed that at the do stage there could be a decrease in overall production costs of Rp 17,405,876.36 for each cast plastic product of Rp 5,505,173.55 per month and for the cast plastic product of Rp 5,505,173.55 per month.
