The economic conditions of salt farmers and the quality of their salt often put them in a weak bargaining position, so the price of salt at the farmer level is low. Small-scale consumption salt processing machines need to be designed to increase the value of salt so the welfare of salt farmers can increase. This study aims to design a salt washing machine to increase the NaCl content and remove other impurities such as CaSO4, MgSO4, MgCl2 and others. The machine is designed with stirrig system by maintaining the baume value in mixture of salt and brine at a value of 25-280Be. The machine is equipped with a baume sensor to control the brine baume value. The variable of washing time is varied to produce the best salt quality. This research has designed a two-level salt washing machine with a 0Be controll system that can wash salt with brine in 50 kg/hours capacity. This machine washes the salt in 2 step process. Salt washing machine driven by a 1.5 HP electric motor to stir the salt with brine so it can dissolve the impurities and retain the NaCl in crystal form. The purity of NaCl in salt increased by 7.5% after being washed for 20 minutes.

The salt washing unit is part of the salt processing machine. This unit's function is to wash raw salt with brine. This unit has a motor, agitator blade, washing chamber, and frame. The frame structure strength of the salt washing unit needs to be evaluated to ensure safety. This research aims to design the salt washing unit and obtain simulation results of frame structure strength to ensure the safety of the salt washing unit. This research was carried out by simulation to look for stress, strain, and changes in the shape of objects (displacement). The frame strength simulation was carried out using Solidwork software. The salt washing unit with a 50 kg/hour capacity has been designed. It has a cylindrical shape with 990 mm in height and 680 mm in diameter. From the simulation results of strain, it can be concluded that the minimum point is 1.80 × 108 Mpa, and the maximum point is 1.63 × 105 Mpa. From the simulation results of displacement, it can be concluded that the minimum point is 0 mm and the maximum point is 2,296 mm. The maximum stress is 5.254×106 N/m2, and the minimum stress point is 1.803×106 N/m2.

Introduction. A fever-specific, reliable animal model is necessary to screen the antipyretic activity of pharmacological agents, especially to differentiate their action from broad anti-inflammatory activity. The present investigation was directed towards standardizing the yeast-induced pyrexia model in Sprague Dawley rats for screening the antipyretic activity of paracetamol. Methods. Male Sprague Dawley rats were placed into three groups (5 each): normal control, pyrexia-induced untreated, and paracetamol-treated. Pyrexia was induced by subcutaneous injection of 40% aqueous suspension of Saccharomyces cerevisiae (10 mL/kg b.w.). Paracetamol-treated rats were given a single oral dose of 150 mg/kg following pyrexia induction. Rectal temperature was measured at intervals of 30 minutes for 180 minutes. Results. Saccharomyces cerevisiae injection elicited a satisfactory febrile response in both pyrexia-induced groups. In the paracetamol-treated group, there was a considerable decrease in rectal temperature from 90 minutes, and the difference was statistically significant (p < 0.05) when compared with the untreated group. The model was able to distinguish the antipyretic effect of paracetamol from natural thermoregulatory fall in controls. Conclusion. This S. cerevisiae pyrexia model in mice is a specific and reproducible platform for antipyretic drug evaluation. The ability to dissociate antipyretic mechanisms from accompanying inflammatory processes is what makes it an acceptable model for future pharmacological screens. The addition of fever-specific biomarkers, i.e., hypothalamic metabolites and PGE₂, is suggested to also offer mechanistic insight and translational value.

Salt is a solid and crystalline substance produced from sea water. The salt that we know has a collection of compounds whose main part is Sodium Chloride (NaCl) as well as several impurities such as Calcium Sulfate (CaSO4), Magnesium Sulfate (MgSO4), Magnesium Chloride (MgCl2) and others. The washing process needs to be carried out to remove impurities so that NaCl levels on salt increase. The washing process with stirring in several rotation variations was used to increase the NaCl content on salt. This research aimed to determine the effect of the rotation speed of the stirrer blade in the washing process in increasing the NaCl content on salt. This research used variations in rotation speed of 40 rpm, 80 rpm, and 120 rpm and compared the increasing trend with washing times of 15 minutes and 20 minutes. The experiment showed the best rotation speed in the washing process to obtain the greatest salt content is a rotation speed of 80 rpm. Experiment with variations in rotation speed with washing times of 15 minutes and 20 minutes showed that increasing the rotation speed did not have a significant effect on increasing NaCl content of salt in the washing process.
