Abstract
CV. Batik Krakatoa Cilegon is a manufacturing industry engaged in the production of batik cloth. During production, productivity measurements have never been carried out so that they do not know the level of productivity of the industry itself and in the production process of stamped batik cloth takes a fairly long time of about 2 - 3 days, because in its production activities there are activities that are not value-added or wasteful which results in the use of higher time resources, thus causing inefficiency in the production process. The purpose of this study is to determine the level of productivity, the type of waste and the cause of the dominant waste that occurs in the production process of stamped batik cloth and proposed improvements that can be given to increase productivity. The research begins with productivity measurement using the Objective Matrix (OMAX) method based on several partial productivity criteria. Furthermore, the lean manufacturing approach to identify the types of waste that occur most using Value Stream Analysis Tools (VALSAT). Then analyze the root cause of the waste using Fishbone Diagram to minimize the waste that occurs. The measurement results with the OMAX method showed that the decrease in productivity level occurred in February by -75, April by -69.2, July by - 1.1, September by -27.4, October by -24.4, November by -25.6. Then there was an increase in productivity levels in March by 271.4, May by 306.3, June by 38.5, August by 84.3 and December by 79.1. While the lean manufacturing approach shows that the most waste that occurs is waiting and unnecessary motion. Proposed improvements that can be given are checking raw materials regularly, making work instructions, Standard Operating Procedure (SOP) and providing tools in the form of wall fans. The results of improvements to Process Activity Mapping (PAM) resulted in a decrease in cycle time of 1,876.61 seconds or 5.47%. Total cycle time from 34,278.58 seconds to 32,401.97 seconds. A decrease in lead time of 1,876.62 seconds or 5.44%. Total lead time from 34,502.72 seconds to 32,626.10 seconds. Increased Process Cycle Efficiency from 41.55% to 43.94%.

| Additional Information: | CV. Batik Krakatoa Cilegon merupakan industri manufaktur yang bergerak dalam produksi kain batik. Selama berproduksi belum pernah dilakukan pengukuran produktivitas sehingga belum mengetahui tingkat produktivitas industri itu sendiri dan dalam proses produksi kain batik cap membutuhkan waktu yang terbilang lama sekitar 2 – 3 hari, karena dalam kegiatan produksinya terdapat aktivitas yang tidak bernilai tambah atau pemborosan yang mengakibatkan pemakaian sumber daya waktu semakin tinggi, sehingga menyebabkan ketidakefisienan dalam proses produksi. Tujuan dari penelitian ini adalah untuk mengetahui tingkat produktivitas, jenis waste dan penyebab waste dominan yang terjadi pada proses produksi kain batik cap serta usulan perbaikan yang dapat diberikan untuk meningkatkan produktivitas. Penelitian diawali dengan pengukuran produktivitas menggunakan Metode Objective Matrix (OMAX) berdasarkan beberapa kriteria produktivitas parsial. Selanjutnya, pendekatan lean manufacturing untuk mengidentifikasi jenisjenis waste yang paling banyak terjadi dengan memakai Value Stream Analysis Tools (VALSAT). Kemudian dianalisa akar penyebab pemborosan tersebut menggunakan Diagram Fishbone guna meminimasi pemborosan yang terjadi. Hasil pengukuran dengan metode OMAX diketahui bahwa penurunan tingkat produktivitas terjadi di Bulan Februari sebesar -75, Bulan April sebesar -69,2, Bulan Juli sebesar -1,1, Bulan September sebesar -27,4, Bulan Oktober sebesar -24,4, Bulan November sebesar -25,6. Kemudian terjadi kenaikan tingkat produktivitas di Bulan Maret sebesar 271,4, Bulan Mei sebesar 306,3, Bulan Juni sebesar 38,5, Bulan Agustus sebesar 84,3 dan Bulan Desember sebesar 79,1. Sedangkan pendekatan lean manufacturing menunjukan waste yang paling banyak terjadi adalah waiting dan unnecessary motion. Usulan perbaikan yang dapat diberikan yaitu melakukan pengecekan bahan baku secara berkala, pembuatan instruksi kerja, Standard Operating Procedure (SOP) dan memberikan alat bantu berupa kipas angin dinding. Hasil perbaikan pada Process Activity Mapping (PAM) menghasilkan penurunan cycle time sebanyak 1.876,61 detik atau sebanyak 5,47%. Total cycle time dari 34.278,58 detik menjadi 32.401,97 detik. Penurunan lead time sebanyak 1.876,62 detik atau sebanyak 5,44%. Total lead time dari 34.502,72 detik menjadi 32.626,10 detik. Peningkatan Process Cycle Efficiency dari 41,55% menjadi 43,94%. | |||||||||
