Abstract

Welding machine is a machine that facilitates human work in joining metals. There are two types that are usually used by humans, namely carbide welding machines and electric welding machines. Which both have their respective advantages as a metal connector. This article is lifted from the problem that occurs in the frame or frame on the welding table which experiences severe enough bending of the top frame (head support) which can damage the table frame and the unknown load (force) received by the welding table frame so that the frame is experiencing a bend. Then a design is carried out in the form of a design drawing that can be analyzed for the strength and stress that occurs in the frame which allows researchers to know the load value that is safe to use for the frame. This article aims to reveal the value of the stress that occurs in the frame and the safety value obtained from the design results of the weld table frame structure in the form of technical drawings and structural strength analysis. This article is limited to a loading of 400 newtons. This article examines the design, simulation and stress analysis of the weld table frame structure with a capacity of 400 newtons using the finite element method or also known as Finite Element Analysis (FEA). The material used is st37 iron. Finite element analysis was carried out using a numerical system using the Autodesk Inventor Professional 2020 software. The results of the simulations and also the analysis that has been carried out show that the welding table frame structure has a stress, deformation, mass, and safety factor of 20.0755 MPa, 0.0582948 mm, 40 kg

Abstract

One of the obstacles in raising tapah fish is in the supply of feed. Tapah fish is a carnivorous predatory fish that eats small fish so it is very dependent on live fish feed. For this reason, it is necessary to get used to feeding with artificial feed (pellets). Usually for one time the process of making feed uses a total weight of 10 kg of raw materials and takes approximately 4 hours. This situation is very detrimental to fish farmers because they cannot increase the number of fish and the number of ponds anymore due to limited feed in the form of pellets. Apart from raising tapah fish, the people of Lubuk Gaung Village also have a poultry business, especially chicken livestock. The feed used in this poultry is milled corn feed. In the manufacture of ground corn feed, 60% is corn raw material. Corn grain size is very influential on the growth of poultry. Both of these machines are already sold on the market separately, it's just that these two machines are quite expensive. For animal feed pellet machines, they are sold at a price of Rp. 15,760,000 and a corn grinding machine is sold at Rp. 8,500,000

Abstract

The influence of rotation engine speed to coco fiber and coco peat yieldof coconut fruit from Jambi area has been done. The study aims to know the percentage of cocofiber and cocopeat produced based on the influence of rotation engine speed of decomposition machine starting from 225 rpm, 450 rpm, 750 rpm and 900 rpm.  Each round speed will operate for 2 minutes with 500 grams of raw material and use variation 5 and10 decomposing blades. The result show that(1) the rotational speed of the decomposition machine affects the amount of cocofiber and cocopeat produced. The highest percentage of cocofiber and cocopeat is at 450 rpm (2) The number of blades of the decomposition machine against the percentage of cocofiber and cocopeat produced. The highest percentage of cocofiber and cocopeat using 10 blades. (3) The maximum result of cocofiber and cocopeat obtained from engine speed 450 rpm is 28% cocofiber and 50% cocopeat.

Abstract

Plastic bag type waste is a type of Low-Density Poly Ethylene (LDPE) plastic waste whose presence in Talang Gulo Final Disposal Site in Jambi City is not touched by scavengers because it cannot be resold. This condition resulted in the destruction of this type of plastic bag waste by burning it. Destruction of plastic waste by means of incineration is risky to the environment because pollutants will emit pollutants from CO2, CO, NOx, and SOx exhaust emissions as well as some other pollutants in addition to the general nature of plastic waste which cannot be decomposed by microorganisms on the ground. Efforts to minimize environmental pollution due to plastic bag type waste will be processed using a pyrolysis method using a reactor with temperatures of 250ºC - 450ºC and 65 psi - 65 psi as well as energy-efficient condensers that have high thermal conductivity to produce fuel oil as energy sources. The maximum volume of fuel oil is obtained by a 6hour pyrolysis time of 2,560 ml at a temperature of 450 ºC. The test results for density parameters, specific gravity, water content, flash point, and heating value indicate that the fuel produced meets Indonesian fuel quality standards.

Abstract

With the current waste of rice husk, one way to convert energy-rich agricultural waste into an easy-to-use form by combining it into briquette fuel. Briquette fuel is defined as fuel produced from organic materials. In order for the rice husk to be used to speed up the process of becoming rice husk briquettes in rice husk briquette testing, 5 (five) tests of rice husk briquettes were tested. From the results obtained by rice husk briquettes with tapioca flour adhesive has been successfully made with a mold pressure of 2 Kg / Cm2, while the briquette diameter is 100 mm with a height of 5.cm and 8. cm. The results of testing the rice husk briquette heat value obtained were 5 cm rice husk briquettes of 32,221 cal and 8 cm rice husk briquettes of 32,130 cal, briquette burning rate of 5 cm was 0.054 g / sec and for 8.cm briquettes of 0.071 g / sec, The type of Briquette 5 cm is 0.898 g / cm3 and for briquettes 8.cm is 1.052 g / cm3.

Abstract

Cassava is a type of tuber that is very much found in the Jambi region. Cassava is easily damaged and decayed in a period of about two to five days after harvest, if it does not get good post-harvest treatment. It is necessary to process cassava crops into chips. To get the results of cassava chips that are good, there is a machine that can produce homogeneous chopped results. Besides that, it is expected that the cassava chopper machine can produce chopped with several forms of chopping. This study aims to make the design of multi-blade cassava chopper machines so that three types of chopping shapes can be produced with only one machine. Based on the results of the study, cassava chopper machines were produced with dimensions of length 630 mm wide by 390 mm and height of 450 mm. This machine uses a straight round multi-blade dish, waves and sticks. The capacity of this machine is 54 kg / hour and the power used is 185 watts.

Abstract

PT. Agrindo Indah Perkasa located in the new mining village of Meranginyang Regency produces CPO so far in controlling the supply of its main raw material, namely FFB, which only receives from farmers around because PT. AIP does not yet have its own garden. So that the efficiency of ordering costs and storage costs for raw materials are not optimal. This research was conducted to find out the raw material inventory control system applied by the company, the efficiency of inventory control of raw materials obtained, the analysis of Economic Order Quantity (EOQ) and the extent to which the Economic Order Quantity (EOQ) method can streamline the cost of controlling raw material inventories. is a descriptive method and method of verification method. Based on the results of the study using the Economic Order Quantity (EOQ) method, the number of orders that are economical is 303 tons / month, with the order frequency of 14 times / month. The point of re-ordering was done when the supply of fuel was 1357 tons. The total cost of inventory using company calculations of Rp. 66,300,000, while using the Economic Order Quantity (EOQ) method the company only issues a total inventory cost of Rp. 26,346,428. By using the company EOQ method can save the total inventory cost of Rp. 39,953,572 or 39.74% ...

Abstract

One example of the type of metal waste that can be managed is Aluminum such as used soft drink cans. One of the technological ways that can be developed to process the used soft drink cans is by recycling. The recycling process that can be done is to use a hydrolysis process that is mixing water, NaOH and scrap cans. The hydrolysis process requires the main components in the form of a hydrolysis reactor. In this research a hydrolysis reactor has been designed for the production of hydrogen gas with an operational pressure design of 300 psi, the dimensions of the reactor are 300 mm x 600 mm high. Wall thickness of 1.21 mm. and reactor material from JIS G 3116 plate.
