Abstract

This study aimed to examine the impact of dietary salt-based mineral and phosphorus supplements on mean body weight, survival rate, and feed conversion ratio of Litopenaeus vannamei (white shrimp) reared in brackish water. The experiment was performed randomized design with three replicates in each treatment used twelve 40 L rectangular polymethyl methacrylate containers reared 45 days. The four treatments in this study were based on the concentration of salt-based mineral and phosphorus supplements (control or 0 ppm, one ppm, two ppm, and three ppm) in dietary of white shrimp. The results showed that using salt-based mineral and phosphorus supplements in dietary of white shrimp positively impacts mean body weight, survival rate, and feed conversion ratio. Increasing the concentration of salt-based mineral and phosphorus supplements increased mean body weight and survival rate and reduced feed conversion ratio of white shrimp. The mean body weight, survival rate, and feed conversion ratio of white shrimp were achieved with three ppm of dietary salt-based mineral, and phosphorus supplements reared 45 days was 5.98 gr, 88.57%, and 1.45, respectively.

Abstract

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

The use of bacteria in improving the quality of salt on a laboratory scale is still minimal. Bacteria are found in seawater as raw materials for various types of salt. One of the bacteria that are tolerant to salinity levels in raw saltwater is halophilic bacteria. Exploration of halophilic bacteria isolates contained in seawater as raw material for salt is an effort to provide initial information on the use of these bacteria in improving the quality and quality of salt. This study aims to determine the morphological characteristics and gram grouping of halophilic bacteria contained in raw water, reservoir water, and evaporator water during the traditional salt production process. The methods used in this study were bacterial isolation, purification, and gram staining test. Morphological characteristics were carried out by visual observation of bacterial colonies formed in Petri dishes, while the gram test of bacteria was carried out by staining pure isolates. Morphological characteristics and groupings of gram bacteria were observed under a CX43RF binocular microscope with a digital camera type MDCE-5C. The results of this study found 2 isolates circular in raw saltwater, 5 isolates in irregular, filamentous and circular shapes in reservoir water, and 3 isolates in circular and filamentous shape in purification water. The bacterial isolates found varied in the form of groups of gram-negative bacteria and groups of positive bacteria, while the predominant form of bacteria was bacilli. The results of this study are expected to be initial information that can be used as a reference to improve the quality and quantity of salt production.

Abstract

Indonesia has great potential as a salt-producing country due to its extensive coastline and favorable geographical conditions. However, the quality and quantity of domestic salt production are still suboptimal and fail to meet the domestic industrial salt demand. This study aims to analyze and compare environmental parameters that influence the suitability of salt pond sites in several regions of Indonesia, as well as to understand the salt production process based on the deposition of impurities at various stages of crystallization. The study was conducted at eight locations with different climatological and hydrological characteristics, including rainfall, soil permeability and type, duration of sunlight, air humidity, wind speed, air temperature, evaporation rate, and water saturation. The results of the study indicate that environmental parameters play a role in determining the effectiveness and efficiency of the salt production process. Pati and Aceh Besar districts are classified as unsuitable (N) for soil parameters, thus requiring adaptive technologies such as geomembranes and boiling methods. The salt crystallization process begins with the flow of seawater from the bozem to the crystallization table, where impurities such as mud, sand, Fe₂O₃, CaCO₃, CaSO₄•2H₂O, and gypsum are gradually deposited. Meanwhile, NaCl deposits form on the crystallization table, and MgSO₄ and NaBr compounds are found in the bittern pond. This study emphasizes the importance of land suitability mapping based on environmental parameters to enhance national salt productivity and quality, as well as serving as a foundation for developing more adaptive salt production policies tailored to regional conditions.
