Sakura cake is a traditional food from District Cangkiang, Agam Regency, West Sumatra. This cake has been marketed to Bukittingi, Padang and has been used as a typical food from West Sumatra. In Cangkiang there are a number of similar Sakura cake micro-businesses and still use coconut shell as a moulding cake. However, the production capacity with coconut shell is still low even unable to meet demand. In addition, the use of coconut shell can risk injury to workers. So an innovation is made on the tools that are already on the market and can be used as a substitute for it. In research on productivity calculation using the Objective Matrix (OMAX) method by using production data for six periods. The productivity criteria measured are the use of raw materials, the use of working hours, fuel consumption and electricity use. The results of this study found that achieving the highest score was found in the criteria for use of working hours, at level 9, which was reached at the end of the survey period.

樱花糕是西苏门答腊省阿甘摄政区沧江区的传统食品。这种蛋糕已销往巴东武吉丁宜，并已被用作西苏门答腊的典型食品。在沧江有很多类似的樱花糕微商，仍然使用椰子壳作为成型糕。然而，椰子壳的产能仍然很低，甚至无法满足需求。此外，使用椰子壳可能会对工人造成伤害。因此，对市场上已有的工具进行了创新，可以用作替代品。使用目标矩阵（OMAX）方法通过六个时期的生产数据进行生产率计算的研究。衡量的生产力标准是原材料的使用、工作时间的使用、燃料消耗和电力使用。
