The traditional method of making salted eggs usually using the salting, which is done well, its needs time about 14 days. This condition indicated to have a method that can speed up the process of salting the eggs. The process of salting eggs normally uses the usual soaking method where the eggs are coated with bricks and rubbing ash then left to stand. The diffusion of salt penetration in traditional salting takes place slowly. For this reason, the speed of salt penetration can be done by increasing the salt level in the soaking solution so that the penetration of salt into the eggs can take place faster. This methodology in this research study using of air pressure to speed up the process of salting the eggs. The method used is to use air pressure with the use of compressor air pressure at a pressure of 4 - 6 Bar with a salting test time of about 4 to 7 hours

Seringnya pemadaman listrik oleh PLN di beberapa daerah di Indonesia tak terkecuali di Indramayu, serta naiknya tarif listrik sejak awal tahun 2017 membawa dampak negatif pada rakyat indonesia yang sangat konsumtif dan tergantung pada energi listrik. Sumber energi angin didaerah pesisir Indonesia umumnya merupakan salah satu potensi sumber energi terbarukan (renewable energy resources) yang berlimpah, ramah lingkungan dan bersifat renewable. Turbin angin savonius dapat menghasilkan torsi yang relatif tinggi meskipun pada kecepatan angin rendah. Untuk mendapatkan daya listrik yang besar diperlukan konstruksi turbin yang besar juga dimana memerlukan biaya yang besar juga tentunya. Untuk itu perlu dikembagkan dimensi dari konstruksi turbin angin ini. Aspek yang sudah diteliti adalah penampang sudu, serta nilai lainnya. Sedangkan kedalaman lengkungan atau panjang busur sudu pada tipe U masih berpeluang diteliti. Oleh karena itu perlu dilakukan penelitian pada busur sudu tipe U untuk mendapatkan daya yang lebih besar dari sebelumnya. Metode numerikal dilakukan untuk mengetahui berapa besar pengaruh modifikasi geometri sudu terhadap daya turbin yang terserap. Turbin didesain dengan jumlah sudu 2 buah sesuai dengan penelititan sebelumnya. Parameter yang divariasikan hanya pada geometri panjang busur dan lebar penampang sudu, parameter lainnya mengikuti penelitian sebelumnya. Dari hasil simulasi radius dan lebar penampang membuktikan ada pengaruh geometri dalam peningkatan daya turbin berturut-turut sebesar 7,78 % dan 19,76 %. Variasi sudu yang menghasilkan daya terbesar terdapat pada variasi sudu R 75 dan LP 130 pada kecepatan angin 4,8 m/s.

Ball valve is one type of rotary motion valve. Ball valve functions as a round disc-shaped ball-like controller. Ball valve is widely used because it is easy to repair and the ability in high pressure and high temperature. The fluid flow in the ball valve does not always flow, sometimes the flow is closed. This will affect the fluid pressure in the valve. Fluid pressure is also affected due to valve open condition. This study aims to analyze the difference of the fluid pressure in ball valve -4 inch ANSI during closed condition and open condition. The method used is Computational Fluid Dynamics with f Flow Simulation Solidworks software. The analysis was performed for two valve conditions with a temperature of 425 °C. Decrease in pressure does not significantly affect the condition of the ball valve, even when the temperature of the fluid is high. The difference of fluid pressure between full closed condition and full open is only 0.01 psi.

Generally, wind energy sources in Indonesia's coastal areas is one of the potential sources of renewable energy (renewable energy resources) which are abundant, environmentally friendly and renewable. Savonius wind turbines can produce relatively high torque even at low wind speeds. Because it is very well developed to produce electrical energy. To get a large electric power, a large turbine construction is also needed which also certainly requires a large cost. For this reason, it is necessary to develop the dimensions of this wind turbine construction which is known as aspect ratio (Ar). The Ar that has been researched is the blade section, and other values. While the arch depth or the length of the blade arc in U -type is still likely to be researched. Therefore, it is necessary to do research on the U-type blade arc to get greater power than before. In addition to the experimental method with a prototype of the U type Savonius wind turbine with a number of 2 blades, a software-based simulation method will be carried out to analyze the air flow on the wind turbine blade. Parameters varied only with the aspect ratio of the arc length and blade cross section width, other parameters follow the previous research. This analysis will be a comparative data with experimental methods. The expected simulation results obtain the best aspect ratio (Ar) blade in capturing wind energy.

Pipe connecting system that is connected with a valve using a flange connection. This aims to make it easier to install or disconnect when needed. This connection system includes pipe connections to fittings, valves, equipment, or other parts which are separate parts of the piping system. The analysis of the flange strength on the 4 inch ball valve ANSI 300 aims to determine and ensure that the flange has strength and is safe at the time of tide due to the influence of the torque bolt. In addition, to ensure the connection does not leak when the fluid is passed. The main combination between internal, axial pressure and thermal loading needs to be considered. Flange strength analysis using Finite Element Analysis (FEA) method with use of Solid works software. The analysis of flange strength uses the method of "Flange as weakest part philosophy", namely the full rating used when the value of a certain pressure-temperature on ASME B16.5 is taken for the Maximum Allowable Working Pressure (MAWP) in the piping system. From the results of the FEA analysis, it was found that the flange on the 4 inch ANSI 300 ball valve meets the requirements according to MAWP at different temperatures and pressures. The value of the safety factor also shows that the flange is safe during the piping work process.

The development of the Vertical Axis Wind Turbine (VAWT) is still a challenge for several researchers in the world and in Indonesia. Due to the potential of the Indonesian coast generally has an average wind speed of 3-7 m / s which is classified as low wind speed and is very suitable for VAWT which operates at low wind speeds. Combining the 2 existing VAWT types is one of the development efforts on VAWT to improve the performance of these wind turbines. Hybrid VAWT Savonius-Darrieus can increase the coefficient of performance (Cp) where the maximum Cp of savonius is 30% while Darriues is 35%. There have been several researchers making the Savonius-Darrieus Hybrid VAWT prototype producing Cp above 35%, but this is still far from the ideal Cp of wind turbines around 59%. The combination variation of 2 types of VAWT still has the opportunity to be investigated with various variations in construction and variations in additional accessories. The research method that will be carried out is the prototype experimental method, with the design and prototyping stages. The prototype was tested at the Mechanical Engineering Laboratory of the Indramayu State Polytechnic by blowing the wind at a certain speed from the wind tunnel that had been prepared in advance. There were 11 samples prepared, namely 4 samples for 3 levels and 7 samples for 4 levels. There were 5 samples that reached a Cp value of 0.58 which was close to the ideal Cp value, but there was no increase in TSR in all samples.
