Abstract

ABSTRAKKualitas air laut seperti mineral dan cemaran sangat berpengaruh terhadap hasil produksi garam. Salah satu indikator penurunan kualitas air laut adalah fosfat. Tujuan dari penelitian ini adalah untuk mengetahui hubungan fosfat terhadap kualitas bahan baku garam di Desa Padelegan. Penelitian ini menggunakan metode Purposive Sampling berdasarkan zonasi perairan, dimana sampel air diambil dan di analisa merujuk pada SNI 06-6989.31-2005. Kandungan fosfat tertinggi diketahui berada pada muara sungai dan pantai sebesar 0.1686745 mg/L dan terendah di badan sungai sebesar. 0.12851 mg/L. Hal ini dapat diakibatkan karena daerah pantai dan muara sungai merupakan daerah yang berdekatan dengan sumber cemaran fosfat. Berdasarkan PP RI No.22 Tahun 2021 tentang baku mutu air konsumsi kandungan fosfat di perairan Desa Padelegan masih di bawah ambang batas dan melebihi ambang batas untuk kehidupan biota. . Kandungan fosfat yang tinggi berpengaruh terhadap kondisi fisik garam seperti warna yang tidak putih, serta memberikan cita rasa yang menyimpang (pahit) setelah proses produksi. Kata Kunci: Garam, Zonasi, Fosfat, Bahan Baku, Kualitas Air  ABSTRACTThe quality of sea water such as minerals and contamination greatly affects the results of salt production. One indicator of declining sea water quality is phosphate. The purpose of this study was to determine the relationship of phosphate to the quality of salt raw materials in Padelegan Village. This research uses purposive sampling method based on water zoning, where water samples are taken and analyzed according to SNI 06-6989.31-2005. The highest phosphate content is known to be in river mouths and beaches of 0.1686745 mg/L and the lowest is in river bodies of . 0.12851 mg/L. This can be caused because coastal areas and estuary are areas that are close to sources of phosphate contamination. Based on PP RI No. 22 of 2021 concerning quality standards for consumption water, the phosphate content in the waters of Padelegan Village is still below the threshold and exceeding the threshold for biota life. . The high phosphate content affects the physical condition of the salt such as the color is not white, and gives a distorted (bitter) taste after the production process.Keywords: Salt, Zoning, Phosphate, Raw Material, Water Quality

The research method used is descriptive method with a quantitative approach, taking water samples for seawater samples using a water sampler. 1L of water samples were taken for analysis, then the water samples were put into an aluminum pack. Sampling was carried out at PT Garam Persero Pamekasan. Sediment and water samples were analyzed for calcium content using the Atomic Absorption Spectrophotometer (AAS) test method at the Laboratory of Research and Industrial Standardization in Surabaya. The results showed that the calcium content in seawater samples was 565.58 mg/L, bouzem was 507.25 mg/L, purification was 1254.6 mG/L and soil crystallization table was 286.05 mg/L. The highest yield was obtained in the hatchery pond, which was 1254.6 mg/L.Keywords: Calcium, Raw material water, Bouzem water, Peminihan water, Maduris crystallization table water

Abstract

ABSTRAKKabupaten Bangkalan merupakan suatu daerah yang terletak di provinsi Jawa Timur, yang tepatnya berada pada pulau Madura. Daerah Bangkalan memiliki berbagai macam aneka tumbuhan laut di antaranya rumput laut, lamun, dan juga tanaman yg hidup di daratan pesisir. Penelitian ini bertujuan untuk mengetahui perbedaan proksimat Thalassia hemprichii dan Galaxaura rugosa meliputi air, abu, lemak, protein, serat dan karbohidrat pada lokasi yang sama. Pengambilan sampel dilakukan pada lokasi yang sama dan satu stasiun dengan tiga kali pengulangan, dilakukan pengukuran data parameter kualitas perairan yang meliputi kecerahan, suhu, salinitas, potentional hydrogen (pH), arus dan oxygen terlarut (DO). Hasil penelitian menunjukkan adanya perbedaan kandungan proksimat kadar air, abu, lemak, protein, serat dan karbohidrat. Hasil rata-rata proksimat kadar air Thalassia hemprichii yaitu 16,67% ; kadar abu 69,33% ; kadar lemak 1,25% ; kadar protein 3,21% ; kadar serat 4,96% ; kadar karbohidrat 9,54% . Sedangkan untuk Galaxaura rugosa memperoleh rata-rata proksimat kadar air 16,00% ; kadar abu 43,11% ; kadar lemak 1,24% ; kadar protein 2,33% ; kadar serat 2,18% ; kadar karbohidrat 37,31%..Kata Kunci: Kabupaten Bangkalan, Analisa Proksimat, Lamun, dan Makroalga.ABSTRACTBangkalan Regency is an area located in the province of East Java, which is precisely on the island of Madura. Bangkalan Regency has a wide variety of marine plants including seaweed, seagrass, and also plants that live on the coastal land. This study aims to determine the proximate differences between Thalassia hemprichii and Galaxaura rugosa including water, ash, fat, protein, fiber and carbohydrates at the same location. Sampling was carried out at the same location and at one station with three repetitions, the water quality parameter data measured included brightness, temperature, salinity, potential hydrogen (pH), current and dissolved oxygen (DO). The results showed that there were differences in the results of the analysis of the concentration of proximate content in water, ash, fat, protein, fiber and carbohydrate content. The results obtained proximate average water content of 16.67%; ash content 69.33% ; fat content 1.25% ; protein content 3.21%; fiber content 4.96%; carbohydrate content of 9.54% for Thalassia hemprichii samples. Meanwhile, Galaxaura rugosa obtained an average proximate water content of 16.00%; ash content 43.11% ; fat content 1.24% ; protein content 2,33%; fiber content 2.18%; carbohydrate content of 37.31%.Keywords: Bangkalan Regency, Proximate Analysis, Seagrass, and Macroalgae
