Abstract

The aim of the Community Service Program for the Ampiang manufacturing group partners in the Selindung Lama sub-district, Gabek District, Pangkalpinang City is to increase production capacity and quality and improve the partner's business management system. The survey results found problems in the fish grinding production process carried out by partners still using the manual method. As a result, partners' production capabilities are limited. In addition, from a business management perspective, partners are still not optimal. The average fish grinding ability of partners is 7-10 kg in 4 hours. From the results of the discussion, the production system was improved by holding a fish grinding machine and marketing management training. Making alternative concepts based on data from literature studies, interviews with partners. The alternative concept chosen as the machine design is assessed based on the results of discussions with partners which are seen in the aspects of frame dimensions, machine height, grinder dimensions, motor power used, machine plate size used. The manufacturing production process is carried out in the Mechanic workshop of the Bangka Belitung State Polytechnic of Manufacturing (Polman Babel). The trial results of the fish grinding machine obtained a very fast time of 10 kg/5 minutes. So that Ampiang's production, which was previously only 15 kg, increased to 45 kg. The business management training that was carried out included small/medium business bookkeeping training, and small industry business management training. As a result, the bookkeeping and marketing process is more focused and orders can be made online.

Abstract

In the industrial world has many complex problems about metals, therefore there needs to be a variety of heat treatment on metals in order to obtain the desired product. Therefore, in this study was conducted to obtain data on the effect of heat treatment on the hardness value and micro structure of Amutit steel and the influence of hardening process with three types of enhancing media namely carbon powder, anthracite, and wood charcoal with four variations of cooling media namely Ordinary Water, Sea Water, Ice Water and Oil. With this research is also expected to be useful in the manufacturing industry. The purpose of the study was to obtain optimum hardness due to the process of heat treatment and rapid cooling. Steel material amutit K-460 / AISI 01 is included in the classification of steel tools used in the manufacturing industry to help the production process such as cutting tools and as a mold material for plastic materials. Based on the results of the research that has been done, it can be concluded that Baja amutit or AISI 01 has a hardness of 16.3 HRC without treatment. The hardness of this amutit steel is able to be increased through heat treatment with rapid cooling. Heat treatment done with the addition of activated carbon media is harder in comparison with the addition of Anthracite media and wood charcoal media. The highest hardness is influenced by the form or dimension of activated carbon that is smoother than other media, where the smoother or smaller the dimensions of the enhancer material, the faster the diffusion process occurs. Where the average hardness for the addition of activated carbon media is Sea Water (64.13), Plain Water (63.46), Oil (63.83), and Ice Water (66.2) with HRC units, As for anthracite media, namely Sea Water (58.26), Plain Water (54.76), Oil (51.8), and Ice Water (55.8) with units of HRC and Wood Charcoal media of Sea Water (58.33), Plain Water (51.83), Oil (45.8), and Ice Water (58.8) with units of HRC.

Abstract

This study aims to obtain the required hardness values as a result of the heat treatment process with the addition of carbon powder, anthracite, and wood charcoal followed by rapid delayan and examine the effect of rapid cooling with variations in cooling and the addition of carbon powder, wood charcoal, and anthracite. The materials used in this study were ST.60 steel in the form of selinders, then anthracite media, wood charcoal and carbon powder. Specimens are treated with heat treatment with a temperature of 600°C - 900°C with a containment time of 30 minutes-90 minutes. Then done quenching with sea water cooling media, plain water, ice water and oil. After that, a three-point hardness test was conducted on the surface of the specimen and the test was conducted with Hardness Testing Machines Limited hardness test equipment with Type 8150 LK (United Kingdom). And the method performed is Complete Random Design. From the test results were obtained the required hardness value is in the active karbn media 63.06 HRC by using ice water cooling media and followed by wood charcoal with a hardness value of 54.33 HRC with sea water cooling media while anthracite media hardness value of 52.76 HRC with sea water cooling media. High hardness values are affected by low cooling viscosity and small carbonated material dimensi.

Abstract

Friction welding is a type of welding that connects two materials with the heat generated by the material itself so that it does not require additional materials. Heat can occur due to the presence of two objects rubbing against each other so that the material can melt and there is a connection due to forging process. The purpose of this study was to determine the impact strength of friction welding joints. The material used in this research is low carbon steel St.41 in the form of of a solid cylinder which has a diameter of 13mm. From the research that has been done, it is found that friction welding using 720 and 1000 rpm have better joint strength than using 450 rpm, which means that specimens with 720 and 1000 rpm have a higher amount of energy absorbed and impact values than specimens using 450 rpm.

Abstract

SMAW (Shield Metal Arc Welding) welding is a welding process by joining two or more metal materials using a wrapped electrode as heat energy to melt the material. In this study, the SMAW welding machine was tested at the Polman Babel mechanical workshop to determine the difference (difference) between the current output value of the welding machine and the value indicated by the measuring instrument during welding. Then the deviation number is compared with the permissible current tolerance using the British Standard BS 7570:2000 reference standard, which is 10%. Welding machines that will be tested are 2 models, namely ewm pico 300 and Miller gold star 402 as many as 6 pieces. This research uses St37 steel and the current variations used are 75A, 150A and 225A on the ewm pico 300 and 99A, 198A, and 270A on the miller gold star 402 engine. within the tolerance limit where the largest deviation is found in machine 2 setting 75A, which is 7.46%. On the miller gold star 402 machine, there are 2 machines showing current deviations that are outside the permissible tolerances, which at engine 2 settings 198A and 270A are 16.4% and 10.9%, engine 3 all currents are 19.7%, 19 ,1%, 16,2%.

Abstract

Pantiaw is a typical food originating from Bangka Belitung. The marinade is made from fish and a mixture of other ingredients such as coriander, soy sauce, salt and other flavorings, however, for the process of stirring the pantiaw seasoning, it still uses the manual method. To simplify the process of stirring the pantiaw seasoning, a design for the pantiaw spice mixer was made with a capacity of 10 kg, as well as the SOP (Standard Operating Procedure) and the machine maintenance system, a research method was needed. The method used is the VDI 2222 method which consists of 4 stages, namely planning, conceptualizing, designing, completing. The results of this design process obtained a variant of concept III with a percentage of the technical aspect assessment of 80% and the percentage of economic assessment of 100%. The results of the calculation of the container capacity of 21 kg using a motor power engine of 1 Hp with 1400 rpm, and using a pulley and V-belt belt type A with a shaft diameter of 32 mm and a v-belt length of 1321 mm. The maximum stress that occurs on the shaft diameter of 25 mm is 5 x 10-1 N/mm2
