Along with the times, the need for technology is increasingly needed to support increasing human needs, including in the agricultural sector, where a tool is needed to dry rice quickly after going through the harvest process, therefore a Blower Machine for Drying Rice is made. The blower used in the rice drying process is a centrifugal type with a curved blade, the workings of this blower machine is to pour rice into a room with an area of 5 x 12 m which has been installed in a series equipped with a screen that has a height of 60 cm from the ground, and a width of 60 cm. screen maximum of 2.5 mm, redistribute the grain so that it looks evenly distributed with a maximum pile height of 50 cm, then turn on the combustion furnace with gas fuel so that the temperature reaches 135℃, then turn on the driving motor, and wait until the water content in the rice reaches 13.8 -14%. Because according to the Indonesian National Standard (SNI) for milled dry grain, the recommended moisture content is 14%. From the analysis results, it is found that the blower is able to provide heat of 44.4 for 1000 Rpm blower rotation, and 40.2 for 818 Rpm.

Poros adalah suatu bagian stasioner yang berputar, biasanya berpenampang bulat dimana berpasang elemen-elemen seperti puli, flywheel, engkol, dan elemen pemindah lainnya.. Poros bisa menerima beban-beban tarikan, tekan, lenturan atau puntiran yang bekerja sendiri-sendiri atau bergabungan satu dengan yang lainnya. Bila beban tersebut bergabung kita dapat mencari kekuatan statis dan dinamik. Salah satu mesin yang menggunakan poros dan sabuk puli sebagai transmisi yaitu mesin penggiling sekam padi menjadi bahan pakan ternak. Rancang bangun mesin penggiling sekam padi menjadi pakan ternak (dedak) perlu memperhatikan kinerja poros sebagai salah satu komponen utama dari proses penggilingan. Tujuan penelitian ini yaitu menganalisis von mises stress, tegangan geser maksimum, dan safety factor dari desain poros mesin yang telah dibuat portabel dengan sistem simulasi menggunakan software ansys R3 2019. Permodelan tiga dimensi dan analisis poros menggunakan perangkat lunak (Ansys) dengan metode elemen hingga (finite element method). Dari hasil analisis, didapatkan nilai von mises stress pada poros minimum sebesar dan maksimal sebesar , tegangan maksimum dengan nilai minimum sebesar dan nilai maksimum sebesar , serta nilai safety factor minimum 0.093825 dan maksimum 0.056296. Berdasarkan hasil penelitian desain poros penggiling sekam padi yang telah dibuat dikategorikan aman secara teknis. The shaft is a stationary rotating part, usually round in cross section which is attached to elements such as pulleys, flywheels, crank, and other shifting element. Shaft can accept tensile, compressive, bending or twisting loads acting alone or in combination with one another. When these loads are combined we can find static and dynamic forces. One of the machines that uses a shaft and belt pulley as a transmission is a machine that drinds rice husk into animal feed ingredients. The design of the rice husk grinding machine into animal feed (bran) needs to pay attention to the shaft performance as one of the main components of the milling process. The purpose of this research is to portable analyze the von mises stress, maximum shear stress, and safety factor of the machine design that has been made with a simulation system using the ansys R3 2019 software. Three-dimensional modeling and shaft analysis using software (Ansys) with the finite element method. From the results of the analysis, the von mises stress value on the minimum shaft is 10000 and the maximum is 6666, the maximum stress with a minimum value of 7777 and a maximum value of 8888, and a minimym safety factor value of 0,093825 and a maximum of 0,056296. Result based on the research on the design of the rice husk grinding shaft that has been made technically bonded.

A rice drying machine is a machine that functions to dry rice where the working system uses a blower and also a heating furnace to channel hot air which ultimately dries the rice in the drying process, the rice is placed in a holding tank where at the bottom of the reservoir there is space or a cavity to channel hot air. fired by a blower. The components in the Rice Dryer Machine are Blower, Cover Blower, Shaft and Frame. In the rice dryer blower there are wings that surround the cover which functions to concentrate the air going to the blower to be fired, the wings on this blower cover must have the same length and width. suitable for optimizing the work process on the blower. This research aims to make malls or tools that can be used to make it easier for workers to make wings so that the production process runs more optimally and the wings made will be more precise. The data obtained from the research is by measuring the object using a measuring instrument and then conducting a case study to find data on the specifications and components of the rice dryer. The results obtained from this design are the length of the mall is 39.25 cm, the height of the mall is 3.925 cm, the angle of the mall is 45°, the number of wings to surround the cover is 8 wings, the overall time of making the wings after using the mall is 2.880 seconds, the materials used namely Black Iron Plate / Base Plate. From the calculation of the overall time of making the wings before using the mall, it takes 4,800 seconds and it can be concluded that after the design of the mall/tools the time of making the wings becomes much faster.

A simple machine is identical to its function, which makes it easier for work or business, such as cutting time to do work, can be used to change the direction of force, and can save energy expended. In a car suspension spare parts company, there is a problem moving the Y4L hanger from the Y4L hanger to the Daisa storage area in the distribution of parts from the assembly process to the painting process. The problem with this process is the removal of the Y4L hanger by two manpowers. One of the manpower lifts directly and holds a y4l hanger weighing 25 kg, and moves it a distance of ±1.5 m. based on existing problems, it is necessary to make improvements by designing proposed tools that aim to facilitate manpower work. The stage in the proposed design of the tool consists of a description of the problem, the design objectives, the design process. The final result of this research is the proposed lever design as a tool to facilitate manpower activities and can save one manpower and several wasted costs, and can cut time. The dimensions of the tool made are: 87.94 cm long, 120 cm high, 66 cm wide.

A sprocket is a serrated wheel that is attached to a chain, track, or other long serrated object. Sprockets are different from gears. Sprockets never come into contact with other sprockets and never match. Sprockets are also different from pulleys in that sprockets have teeth while pulleys generally do not have teeth. Sprocket is one of the components of a motorcycle that is paired with a chain that is used to transmit rotary force from the engine to the rear wheels. The purpose of this research is to obtain analysis and calculation of the diameter of the sprocket and the analysis that occurs in the chain. From the results of the calculation on the gearsprocket above, if the power generated by the motorcycle is 11.9 hp at 7500 rpm (maximum rotation) and the torque produced is 0.83 kgf.m at 5500 rpm, the resulting motorcycle sprocket diameter is 15. eye size (????1) = 45,836 , diameter of motorcycle gear with 45 points (????2) = 136,618 , average speed of chain (????) = 17,868 /????, average circumference force(????) = 496,4181 , the additional centripetal force of 420 N becomes, 825N, Chain length (m) = 1.09 m.

Along with the times, the need for technology is increasingly needed to support increasing human needs, including in the field of tourism, where supporting facilities are needed so that visitors feel comfortable, one of which is lighting for waterfall tours. The design of a Micro Hydro Power Plant that can be used as lighting on the waterfall path and can also be used for other things. In the design of PLTH, various components have a relationship where when the Nozzle Diameter is used, namely, 0.20 m, 0.15 m, and 0.10 m, it produces speeds of 12.5 m/s, 82.3 m/s, and 18.5. m/s while for the power generated 233.65 Kw the amount of electrical power is the diameter of the nozzle which has an impact on the speed that hits the turbine blades and also the height of the penstock has a big effect because the higher the penstock, the greater the electricity generated because the higher the penstock, the power on the shaft. is also increasing so that the discharge becomes a parameter that affects the shaft power, the greater the water discharge, the greater the shaft power.
