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.

GAKI (Gangguan Akibat Kekurangan Iodium) merupakan masalah kesehatan serius yang menyebabkan kualitas hidup dan perkembangan individu. Uji Eksperimental terhadap kualitas kadar garam berbasis variasi putaran dan waktu pengadukan penting untuk membantu mencegah GAKI, dengan mempertahankan nilai baume dari air tua pencuci garam pada nilai 25-28. Penelitian ini bertujuan untuk menguji kualitas kadar garam yang dihasilkan oleh mesin pengolahan garam dengan variasi putaran (40, 80, dan 120 rpm) dan waktu pengadukan (10, 15, dan 20 menit) dengan kadar awal yang digunakan dalam penelitian sebesar 85.67%. Hasil penelitian menunjukkan bahwa variasi putaran dan lama pengadukan sangat berpengaruh terhadap kualitas kadar garam. Pada penelitian ini dapat disimpulkan bahwa kecepatan putaran mesin 120 rpm dan lama pengadukan dibawah 10 Menit mendapatkan kenaikan kadar garam yang optimal sebesar 6.88% menjadi 91.55%.

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.

Tanaman selada merupakan salah satu tumbuhan yang sering dibudidayakan secara hidroponik. Suhu optimal dalam penanaman tumbuhan selada sendiri yaitu pada kisaran 18 °C sampai 24 °C serta diperlukan kondisi nutrisi yang spesifik yaitu 560-840 ppm. Pengecekan yang dilakukan secara teratur, menjadi tantangan tersendiri karena harus dilakukan terus menerus. Tujuan dari penelitian ini adalah membuat sistem monitoring suhu air dan nutrisi kebun hidroponik untuk tanaman selada berbasis IoT. Sistem dibangun menggunakan argoritma yang sudah ditanamkan pada microcontroller Arduino Mega 2560 dan Esp32, sistem menggunakan LCD dan aplikasi Blynk untuk menampilkan monitoring dan notifikasi. Adapun untuk sistem pendingin menggunakan sistem pendingin peltier. Hasil dari penelitian ini didapat nilai akurasi pengukuran sensor suhu sebesar 98,72% dan sensor TDS sebesar 91,89%, kedua sensor ini layak untuk digunakan.

The raw salt should be reduced the size to convert it into consumption salt. Salt crushing machine generally was designed to reduce salt grain size using rollers for crushing. The small-capacity salt-crushing machine should be designed to meet the needs of small businesses. This study aims to design a salt-crushing machine in a small capacity with a proper power transmission system that will be applied to a roller-type salt crusher. The transmission system is designed to upgrade the performance of roller-type salt crushers through V-belt and pulley transmission mechanisms and obtain the appropriate size or type of V-belt and pulley based on the capacity of the drive motor. The results show power required to crush salt by this system is 299.46 W. The motor used is a single-phase AC motor that has a power size of 1/2 HP, and the corresponding v belt is type A with a size of 51 inches, the rpm needed is 360 rpm, and the distance between rollers is 0,7 mm. Then the pulley needed is with a ratio of 1: 4. The pulleys used are type A1 which has a diameter of 3 inches and 12 inches. The average salt weight loss after the crushing process was 14.27%.

Padaluyu is one of the villages in Cugenang District, Cianjur Regency. Padaluyu Village has an area of approximately 595,110 ha. Currently, in the Padaluyu village area, Kampung Kabandungan RT 04/RW 03, Cugenang District, Cianjur Regency, there was an earthquake of Mw 5.6 on Monday, November 21, 2022. This event has resulted in damage to residents' houses, infrastructure, and residents' agricultural land. The purpose of this activity is to provide assistance to increase the resilience of the people of Kabandungan village and Barujamas village, Padaluyu village, Cugenang sub-district, Cianjur district through the reconstruction of earthquake-resistant buildings and post-earthquake aquaponic farming training. Improving the understanding of earthquake-resistant buildings is carried out through the presentation of earthquake-resistant building materials and visual simulations. Aquaponic farming training is carried out by exposing aquaponic farming material, making aquaponic buildings and installations, and practicing aquaponic farming. The result of this activity is that the people in RT 03 RW 04 and RT 03 RW 07 gain increased knowledge and understanding about the construction of earthquake-resistant housing which can be applied in the construction or repair of post-earthquake residents' houses. Residents' understanding of modern agriculture using the aquaponic method increases and residents can practice aquaponic farming by utilizing their yards to meet their food needs for vegetables and side dishes. The Head of Padaluyu Village hopes that this training can motivate the community to build houses and make very good use of vacant land.
