The purpose of this study was to determine the magnetic mineral content found in the iron sands of Depok Beach, Muara Beach and Sigandu Beach, Batang Regency. Iron sand samples were taken from Depok Beach, Muara Beach and Sigandu Beach, Batang Regency. Sand is extracted using a permanent magnet to separate magnetic and non-magnetic sand. The magnetic sand that has been separated is tested for the type of mineral content by XRD (X-Ray Diffraction). The results showed that the type of magnetic mineral sand from Depok Beach, Muara Beach and Sigandu Beach, Batang Regency, contained Geothite (FeO2), Hematite (Fe2O3), Maghemite (Fe2O3) and Magnetite (Fe3O4) compounds. Calculation of the crystallitesize value on the iron sand of Depok Beach is 45.67, Muara Beach is 33.34 and Sigandu Beach is 33.11.","PeriodicalId":191192,"journal":{"name":"Journal of Natural Sciences and Mathematics Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130859688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in general, this cultivation still uses artificial chemical plants which have a negative impact if used continuously for plants, soil, and consumers. Seaweed besides being able to be consumed by the body, it can also be used as a liquid organic base. The content of seaweed in the form of calcium, manganese and potassium can actually increase plant growth. This study aims to determine the effect of liquid fertilizer applied by researchers on the growth of mustard plants. The method used is to make fertilizer made from seaweed and river moss. Giving liquid fertilizer to mustard plants with various percentages and measuring the height of mustard plants every 5 days for 25 days. The results showed that the application of organic fertilizer with seaweed as the base material could increase the growth of mustard plants. Seaweed-based fertilizers contain K2O which can stimulate growth hormone growth. This is evidenced by the difference in plants given liquid fertilizer made from seaweed and river moss.","PeriodicalId":191192,"journal":{"name":"Journal of Natural Sciences and Mathematics Research","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115703228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is necessary to take effective way to remove heavy metal ions from waters. Adsorption method is widely used because it has several advantages, namely high efficiency, easy handling, reusable, inexpensive, and many choices of materials that are used as adsorbent. One effective adsorbent used is a zeolite because it has high selectivity. This study aims to determine the kinetic model suitable for the process of Cd2+ and Zn2+ metal ion adsorption using Zeolite 4A as an adsorbent. The study was conducted by varying the contact time (10, 15, 30, 45, 60, 90, 120 and 180 minutes).
