The management factor of the salt-making process needs to be considered. Site selection and seasons are essential to support salt salting. The windmill owned by farmers still using wooden material made annually is ineffective and the form of windmills being made does not meet the requirements without considering the wind speed. The pumping speed control is influenced by the size, weight and variation of the blade number and the size of the windmill affecting salt productivity, to optimize the function of the salt water pump by changing the blade material on the windmill by using composite materials and changing the variation of the blade number on the windmill which is 2,3,4 and 6.Test results using blower (fan) showed that the pump will be fully loaded only when the number of blade is 3, 4 and 6 with a speed of 3.49 m / s. As for power coefficient results, the increase of blade number leads to the greater the power efficiency produced. So from the results of simulations and lab tests the authors recommend variations in the number of blade 3.4 and 6. But the fact testing in the lab for variations in the number of blade 6 requires a high speed to start playing Blade, so Blade 4 is most recommended.

Perkembangan zaman saat ini menuntut masyarakat agar lebih maju dan produktif terutama di bidang pangan yang bersumber dari laut. Salah satu sumber pangan yang saat ini memiliki kebutuhan yang tinggi adalah garam. Tidak hanya masyarakat namun kebutuhan industri pangan juga tinggi (Dinas Perikanan dan Kelautan Kabupaten Indramayu, 2013). Kebutuhan garam yang tinggi berdampak pada ketersediaan garam yang ada belum mampu terpenuhi dikarenakan belum optimalnya pengelolaan ladang garam dan para petani belum mampu menerapkan teknologi yang saat ini sedang berkembang. Kabupaten Indramayu merupakan pemasok garam di daerah Jawa Barat setelah Kabupaten Cirebon, namun masih butuh perhatian terhadap ratusan petani garam di Pantura untuk meningkatkan kualitas dan produksi garam mereka, sehingga mampu bersaing dengan produsen lain (Solihin, 2012).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
