Washing clothes is an important activity in everyday life, but it requires time, effort and money. Currently there are many washing machines manufactured by products on the market with one-tube and two-tube types that use electrical energy and digital modules as their operating tools. In this study, the application of CVT (Continuously Variable Transmition) in Mechanical Drive Washing Machines is designed, which utilizes human power as a resource so that it can reduce the use of electrical energy and can save costs besides that it can also be a means of exercise. The washing machine tube rotation is generated from the pedal stroke, which is passed from the sprocket or chain ring to the CVT which then goes to the pinion gear as changing the axial CVT rotation position to radial to rotate the washing tube.

Pipa owned by PT. XYZ located in TambunBekasi is a gas pipeline 8 "along 35 km of gas from BabelanBekasi towards TegalGedeCikarang where the consumers of gas use is one of the Power Plants for Industrial Estates. The pipe passes through several river crossings, provincialroads and also residential areas. With the Government program on the planned construction of the Container Port in the Babelan area of Bekasi, the pipes belonging to PT. XYZ must be made new, and relocated again to theaccess under the river that the container ship will pass. To support the program, PT. XYZ performs data collection on the operating pipeline and also calculates the costs forthe shutdown method and without shutdown. The resultsof this study indicate that the condition of the pipe is in a safe condition and is ready for the Hot tapping method. Based on calculations according to API 570 standards and ASME B31.8 the pipeline can still operate up to a maximum pressure of 1325 psi, and the calculation of pipe life is up to 38 years. Whereas in terms of economics the method without shutdown only costs USD 204,892, - compared to the shutdown method of USD 2,087,187, -The end result is that it can be seen that the non-shutdown method is more efficient than the shutdown method on the gas pipeline in terms of costs as well as capital returns or ROI (Return of Investment) up to 95% and has a new pipeline network for adding potential customers who can increase income PT. XYZ.

Bearing Damage Analysis on the Installation Process using the Envelope Analysis Method aims to produce alternative scientific sources and even new scientific sources in the future for both the needs of workshops and the needs of industrial machines that require bearings with a high level of precision, such as boiler machines, chillers etc. After carrying out the envelope analysis method, namely performing a bandpass filter in the range of 500 Hz – 2000 Hz, rectification, and FFT, it can be concluded that the method is not clear enough to show the peaks caused by damage to the rolling bearings. Although there are several peaks that are close to the Bearing Fundamental Frequency, they have relatively smaller amplitudes compared to other peaks under conditions of external track damage, rolling elements, and combination damage. And in the analysis of this installation so that it can be used by industry and people who usually use bearings in installation so that they can find out a good and correct installation so that the bearing does not get damaged quickly, it uses the type of installation and shaft with what tolerances so that the bearing used is durable or resistant. long and also so that the machine used does not have many obstacles in the process of use.

The clutch spring (spring compression) serves to press the pressure plate so that the clutch lining is close to the clutch plate, so that the clutch does not slip. In addition, the clutch spring also functions to relieve the pressure between the clutch lining and the clutch plate. The force or load applied to the original spring is 2.02 N, and the force applied to the TDR spring is 2.5 N. Load analysis to determine stress and strain using Autodesk inventor software. The simulation results can be concluded that the stress (Stress) that occurs in the standard spring is the largest (Maximum Stress) occurs in the YY vector direction with a value of 37.56 MPa, and the smallest stress (Minimum Stress) occurs in the YY vector direction with value -57.21 MPa. While the stress that occurs in the TDR spring is the largest (Maximum Stress) in the direction of the YY vector with a value of 33.49 MPa, and the smallest stress (Minimum Stress) occurs in the direction of the YY vector with a value of -31.22 MPa. The largest strain (Maximum Strain) occurs in the YY vector direction with a value of 2.45 ul, and the smallest stress (Minimum Strain) occurs in the YY vector direction with a value of -3.61 ul . While the strain (Strain) that occurs in the TDR spring is the largest (Maximum Strain) occurs in the direction of the YZ vector with a value of 1.757 ul, and the smallest stress (Strain) (Minimum Strain) occurs in the direction of the YY vector with a value of -1.863 ul.

Soil cultivation is carried out by utilizing human power, utilizing animal power, and using tools such as hoes to equipment that uses machine power, one of the tools to carry out activities such as land cultivation is a tool called a cultivator . The conventional cultivator has several drawbacks when it comes to tilling the soil, namely the wheel needs to be replaced with a rotary then the operator holds the handle while walking behind the cultivator to do the tillage. The method of this research is to modify the cultivator with a rubber track design using the autodesk inventor application and efficiency analysis on the cultivator as well as calculating the comparison between hoes, conventional cultivator s and also modified cultivator s by comparing the time needed to cultivate the land with a land area of 1 Ha. The results on the rubber track system are more efficient and more productive because the time required for tillage with a land area of 1 ha only takes 8.47 hours while the hoe takes 167.33 hours and conventional cultivator takes 9.09 hours.
