Making a tool that can help cut natural fiber composite raw materials (pineapple fiber) automatically, can increase efficiency and make it easier to cut, both in terms of speed, power, amount of production, to the safety factor of the cutting machine. The results of the test show that using a pneumatic system pineapple fiber cutting tool can cut fibers quickly to meet the need for pineapple fiber as a raw material for composite materials and also avoid situations where when cutting fibers manually you will feel tired because performance decreases and it greatly affects safety level that can be dangerous in the cutting process. The difference in pressure applied to the system varies by 2, 3, 4, 5 bar with varying cutting results, namely 61, 100, 113, and 150 cuts every 60 seconds. This pneumatic system pineapple fiber cutter is capable of cutting in 0.41 seconds with an air pressure of 5 bar.

Chlorine solution, is usually used as a water disinfectant, which can cause metal corrosion. Circulating solution can erode the protective layer thereby accelerating corrosion. Epoxy primer provides the best rust prevention and adhesion properties compared to other types of primer. This research was conducted using 27 specimens in 3 vessels in each vessel there were 9 specimens with soaking low carbon steel without treatment, which was coated with paint and coated epoxy primary. The volume of 1 liter of chlorine solution for 1 vessel. The results of this study indicate that the primary epoxy coated can hamper corrosion well. Low carbon steel weight reduction that without treatment or which is not coated much larger than in low carbon steel coated with paint and coated epoxy primary even though the paint coated is still unable to withstand the corrosion rate well. The lowest corrosion rate with the provision of primary epoxy in a 60-day immersion time with an average value of 0,002879872mpy and the highest corrosion rate with without treatment or which is not coated with a 15-day pronounce time with the average value 0,009015251 mpy.

A plate bending machine or what is called a bending machine, is the process of forming sheet metal (plate) so that it conforms to the planned shape and size. This research applies hydraulic technology to the plate forming and bending process. This bending machine applies a clamping mechanism to the plate and applies a load using hydraulic power to bend the plate. In making this bending machine, it is necessary to analyze the material requirements and the production process chain for an effective hydraulic plate bending machine. Making a hydraulic plate bending machine is divided into several steps that must be carried out and prepared first, namely: Identifying work drawings, planning material selection, preparing materials, preparing tools and machines, carrying out work and finishing processes. The materials used to make components of the hydraulic plate bending machine are 0.6 mm thick ST37 plate with components in the form of clamp parts measuring 1400mm X 196mm 250mm x 95mm, Frame part measuring 1000mm x 600mm. The transmission system used is a hydraulic system to push the bending part. Then, to lift the plate clamp part, use the lever system on the left and right of the hydraulic plate bending machine. The machines and equipment used in making hydraulic plate bending machines are measuring equipment, volume reduction equipment, welding equipment, assembly equipment and finishing equipment.

The hydram pump is a water pump that is energy efficient and environmentally friendly. The hydram pump is an appropriate technology in the field of pumping that uses water momentum (water hammer) to raise water, so the hydram pump is one of the water pumps that does not use fuel and electricity. Much research has been carried out regarding hydram pumps, but there is still much that needs to be studied so that knowledge about hydram pump planning is better. The effective performance of a hydram pump is influenced by several parameters, including drop height, pipe diameter, pipe type, characteristics of the waste valve, length of the inlet pipe and length of the pipe on the waste valve. The water source comes from the Unand Dam River flow, with variations in the height of the water source, namely 0.7m, 1.3m and 1.9m. with water flowing using an inlet pipe with a pipe diameter of 2 inches with a pipe length of 8 meters, and an outlet water pipe with a diameter of 1 inch with a height of 8 meters. The first test with a water source height of 0.7m obtained an inlet water pressure of 1.1 bar and an outlet water pressure of 1bar, with an outlet water pipe height of 8 meters which resulted in an outlet water discharge of 0.037 (L/second). In the second test with a water source height of 1.3 m, the inlet water pressure was 1.3 bar and the outlet water pressure was 1.2 bar, with an outlet water pipe height of 8 meters which resulted in an outlet water discharge of 0.071 (L/second). And in the third test with a water source height of 1.9m, the incoming water pressure was 1.4 bar and the outgoing water pressure was 1.3 bar, with an outgoing water pipe height of 8 meters which resulted in an outgoing water discharge of 0.091 (L/second).

The fisheries industry is one of the important sectors in the Indonesian economy. One crucial aspect in fish farming is the provision of high-quality and continuous feed. Fish pellets are the main choice because of their balanced nutritional content and ease of use. So far, fish pellets available on the market are often imported from large producers who dominate the market. Therefore, an alternative solution is needed that allows farmers to produce their own fish pellets with reliable quality and more economical costs. The creation of a drive system on a fish pellet molding machine is an effort to increase the efficiency of producing quality and affordable fish feed. The working principle of this drive system uses a mechanical energy conversion mechanism from an electric motor to the grinding and molding components. The electric motor functions as the main source of power, which is then transmitted through a gear or belt system to the grinding section to crush raw materials and mold pellets according to the desired size. The process of making the drive system involves calculating the engine pulley rotation of 1400 rpm while the driven pulley rotation is 437.5 rpm, the belt speed is 464 cm / s and the torque is 1,660.80 kg.mm. The test results show that the machine is capable of producing pellets after 3 tests with variations in the weight of the pellet raw materials, the results of the first test were 15.65 kg/hour, the second test 26.47 kg/hour and the third 26.67 kg/hour and the average result was 68.79 kg/hour.
