Madura Island is one of the largest salt producing areas in Indonesia. Salt is included in the type of complementary ingredients in every dish. Rich Mineral salt is salt obtained from the total crystallization process without removing various minerals contained in the raw materials, so that the mineral content is higher than consumption salt in general. This study aims to describe the fluctuations and the relationship between physical parameters consisting of water temperature, water density and water level during the salt production process. This study uses three prototype geomembranes with a size of 60x40x16 cm in salt production. This study uses quantitative methods in the form of numbers obtained based on facts in the field. The results of this study are that the three prototypes have a temperature range, water density and water level that are not significantly different. This is showed by the results of the ANOVA test, where the P-value of the three prototypes is greater than the alpha value (α). In this study also obtained a correlation value between the parameters of water density and water level. The correlation value resulting from the calculation of the linear equation between the two parameters is 0.93. Based on these results, it can be interpreted that the water density and water level have a correlation relationship of 93%. So, it can be concluded that the higher the water level, the lower the water level.

ABSTRACT Estuaries are dynamic waters that are dominated by tides, so these waters are classified as fertile. The fertility of the estuary cannot be separated from the high abundance of phytoplankton, nitrate and phosphate. Nutrient values and abundance of phytoplankton can be influenced by the phenomenon of tidal sea water. The purpose of this study was to determine the differences and the correlation between the concentration of nitrate phosphate and the abundance of phytoplankton at high and low tide. The method used in this research is descriptive quantitative and purposive sampling. The data obtained were analyzed using SPSS 16.0 software. The results showed that nitrate concentrations at high tide ranged from 0.28 to 13.49 Mg/L while at low tide it ranged from 0.31 to 15.60 Mg/L. The concentration of phosphate from the results of the study, namely at high tide, ranged from 0.01 - 2.39 Mg/L, while at low tide it was 1.09 - 3.92 Mg/L. The abundance of phytoplankton obtained at high tide ranged from 165,900 - 1,554,000 Ind/L while at low tide it ranged from 80,500 - 373,100 Ind/L. From the results of SPSS 16.0 analysis, it is known that the difference in nitrate concentration at high tide and low tide is 0.710 0.05, which means that the nitrate concentration at high tide and low tide is not significantly different. The difference in the concentration of phosphate and phytoplankton at high and low tides were 0.004 0.05 and 0.003 0.05. which means the concentration of phosphate and abundance of phytoplankton is significantly different. Analysis of the relationship between the concentration of nitrate, phosphate and the abundance of phytoplankton at high tide has an R value of 0.94 which is categorized as a very strong correlation. While the relationship between the concentration of nitrate and phosphate with the abundance of phytoplankton at low tide is 0.64, it can be categorized that there is a fairly strong correlation.

Fitoplankton merupakan mikroorganisme yang memiliki pigmen klorofil sehingga dapat melakukan fotosintesis. Dalam proses fotosintesis fitoplankton membutuhkan cahaya matahari, sehingga cahaya matahari menjadi faktor utama terhadap perkembangbiakan fitoplankton. Selain itu intensitas cahaya dapat mempengaruhi tinggi rendahnya suhu suatu perairan, sehingga suhu juga akan berpengaruh terhadap distribusi dan keberadaan fitoplankton. Penelitian ini akan menjelaskan korelasi intensitas cahaya dan suhu dengan kelimpahan fitoplakton di perairan estuari. Metode yang digunakan adalah regresi linier sederhana untuk mengetahui korelasi intensitas cahaya dan suhu terhadap kelimpahan fitoplankton. Hasil analisa data intensitas cahaya terhadap kelimpahan fitoplankton menunjukkan nilai R2 = 0,087 yang artinya bahwa kelimpahan fitoplankton dipengaruhi oleh intensitas cahaya sebesar 8,7 %, dan 91,3 % dipengaruhi oleh faktor lain. Sedangkan hasil analisa data suhu terhadap kelimpahan fitoplankton menunjukkan nilai R2= 0,016 yang artinya bahwa kelimpahan fitoplankton dipengaruhi oleh suhu sebesar 1,6 %, dan 98,4 % dipengaruhi oleh faktor lain yang salah satunya adalah intensitas cahaya matahari. Dari hasil nilai R pada penelitian dapat disimpulkan bahwa intensitas cahaya memiliki korelasi rendah terhadap kelimpahan fitoplankton dan suhu terhadap kelimpahan fitoplankton memiliki korelasi sangat rendah.Â Â Â Â Phytoplankton are microorganisms that have chlorophyll pigments, they can carry out photosynthesis. In the process of photosynthesis, phytoplankton need sunlight, so that sunlight is the main factor in the proliferation of phytoplankton. In addition, light intensity can affect the low temperature of a waters, so that the temperature will also affect the distribution and existence of phytoplankton.

Barium (Ba) merupakan salah satu elemen minor di perairan laut yang memiliki nilai ekonomis tinggi apabila dimanfaatkan sebagai produk garam turunan. Sumber utama Ba terlarut berasal dari sungai, dan estuari menjalankan peran penting sebagai pengontrol fluktuasi kadar Ba terlarut pada sungai sebelum masuk ke laut. Penelitian ini bertujuan untuk mengetahui kadar Ba terlarut, distribusi Ba terlarut dan korelasi Ba terlarut dengan salinitas. Kadar Ba terlarut diketahui dari hasil pengujian sampel air laut yang diambil di 9 titik mulai dari daerah estuari hingga laut lepas. Pengujian kadar Ba terlarut menggunakan metode Atomic Absorption Spectrophotometry sesuai SNI 06-6989.39-2005. Kadar Ba terlarut di Perairan Padelegan berkisar antara 0,009-0,003 mg/L. Hasil visualisasi distribusi kadar Ba terlarut tertinggi berada di estuari dan kadar terendahnya berada di stasiun laut lepas. Distribusi Ba terlarut dari estuari hingga laut lepas menunjukkan kadar yang menurun secara bertahap. Hasil korelasi antara kadar barium terlarut dengan salinitas berbanding lurus yang disebabkan oleh intrusi air laut. Barium (Ba) is a minor element in marine waters which has high economic value when used as a derivative salt product. The main source of dissolved Ba comes from rivers, and estuaries play an important role as controlling fluctuations in dissolved Ba levels in rivers before they enter the sea. This research aims to determine dissolved Ba levels, dissolved Ba distribution and the correlation of dissolved Ba with salinity. Dissolved Ba levels are known from the results of testing seawater samples taken at 9 points from the estuary area to the open sea. Dissolved Ba levels were tested using Atomic Absorption Spectrophotometry based on SNI SNI 06-6989.39-2005. Dissolved Ba levels in Padelegan Water range between 0,009-0,003 mg/L. Visualization results of the distribution of the highest dissolved Ba levels are in estuaries and the lowest levels are at open sea. The distribution of dissolved Ba from the estuary to the open sea shows gradually decreasing levels. Correlation results between dissolved barium levels and directly proportional salinity caused by seawater intrusion.

Chaetoceros sp. merupakan fitoplankton yang banyak ditemukan di perairan laut. Chaetoceros termasuk dalam kelompok Diatom dengan kelas Bacillariophyceae. Di laut spesies ini merupakan makanan alami dari Copepoda, salah satu spesies zooplankton. Sedangkan pada budidaya perikanan digunakan sebagai pakan alami Rotifer dan larva udang. Selain itu, spesies chaetoceros termasuk dalam kelompok saprobe yang berperan sebagai indikator biologis perairan yang tercemar sehingga keberadaannya di laut cukup penting. Tujuan penelitian ini adalah untuk mengidentifikasi jenis fitoplankton dari genus chaetoceros yang mempunyai fungsi penting dalam budidaya perikanan. Penelitian dilakukan dengan mengambil sampel air laut dan fitoplankton pada permukaan badan air (0-50 cm) di perairan laut Desa Padelegan Pamekasan. Waktu pengambilan sampel dilakukan pada pagi, siang dan sore hari dengan dua kali pengulangan. Menggunakan jaring plankton dengan ukuran mesh 10 mikron. Identifikasi fitoplankton menggunakan mikroskop Olympz BX41 dengan perbesaran 10x. Berdasarkan hasil penelitian, telah ditemukan 12 spesies Chaetoceros dengan kelimpahan 700–9100 ind/L. Pada malam hari tidak ditemukan spesies chaetoceros karena faktor pembatas pertumbuhan mikroalga adalah sinar matahari. Semakin banyak sinar matahari yang masuk ke perairan, maka semakin banyak pula fitoplankton yang tersebar. Chaetoceros sp is a phytoplankton commonly found in marine waters. Chaetoceros belongs to the Diatom group with the class of Bacillariophyceae. In the sea this species is a natural food of copepod, one of species of zooplankton. While in aquaculture, it is used as natural feed for Rotifers and shrimp larvae. In addition, chaetoceros species are included in the saprobes group, which acts as a biological indicator of polluted waters, so their presence in the sea is quite important. The purpose of this study was to identify phytoplankton species from the genus of chaetoceros which has an important function in aquaculture. The research was carried out by taking samples of seawater and phytoplankton on the surface of the water body (0-50 cm) in the sea waters of Padelegan Pamekasan Village. Sampling time was carried out in the morning, afternoon and evening with two repetitions.using a plankton net with a mesh size of 10 microns. Identification of phytoplankton using an Olympz BX41 microscope with 10x magnification. Based on result, 12 species of Chaetoceros have been found with an abundance of 700–9100 ind/L. At night, no chaetoceros species were found because the limiting factor for microalgae growth was sunlight. The more sunlight that enters the waters, the more phytoplankton are scattered.
