Abstract

The availability of fossil fuels is becoming increasingly limited due to increased innovation in transportation technology resulting in an increase in the number of motor vehicles. The combustion of fossil fuels also has an impact on the environment, such as increasing global warming. This study aims to determine the volume of hydrogen and the flame profile if the plate area is varied. The test was conducted experimentally using 1.3 liters of water. P X L electrodes have sizes (12.5cm x 2.5cm), (11.5cm x 2cm), (10.5cm x 1.5cm), and (10cm x 1 cm). Tests include HHO generator efficiency tests. The test results show that the largest gas production rate occurs in the area of P X L (12.5cm x 2.5cm), producing a volume of 60 ml with a time of 30 seconds and a production rate of 0.002 l/s. The best HHO generator efficiency is obtained at an area of P X L (12.5cm x 2.5cm) of 32.53%.

Abstract

The process of cutting metal or scraping metal using a tool on a machine tool is one type of manufacturing process. In the process of working with machine tools itself, several processes are known such as turning, freis, drilling, grinding and scraping. The difference between these processes is the way of working and the products produced. While this test is about the turning process which is one of the metal scraping processes. The fixed variables used include lathe rotation (RPM) and depth of cut while the independent variable is the coolant used to cool the tool during the scraping process, namely synthetic coolant and seluble oil. By comparing the two coolants, it can be concluded that synthetic coolants have better performance when viewed from tool wear with a standard reference to the critical wear limit of 0.3-0.8 mm. The best performance is using Synthetic Fluid at RPM 650 with a depth of cut of 0.5 mm with a value of 0.05955 mm while the largest wear rate when using Seluble Oil liquid with RPM 1300 with a depth of cut of 1.5 with a value of 0.50495 mm. So it is highly recommended to use synthetic coolant with RPM.

Abstract

Rotary Draw Bending is the most commonly used bending technique in tube bending to achieve good precision results. There are several other bending techniques such as Ram Method, Rotary Method, Roller Method, and Compression Method. In this analysis, an experimental method was carried out by making variations of mandrel models and different mandrel dimensions with a bending angle of 90 degrees. For the measurement process, a digital caliper is used and then the measurement results are drawn with the Mastercam software application. In each rotary draw bending process, the results of SUS 304 stainless steel pipe bending are observed whether they experience wrinkling or smoothness in the bending section. In this experiment, good bending was produced at mandrel diameters tolerating 0.2mm, 0.3mm, and 0.4mm to the inner diameter of the pipe. However, although the results are good at the size of the mandrel with a tolerance of 0.2mm, it should be noted that the process of inserting and removing the stainless steel pipe will have difficulty because it must apply more pressure, sometimes having to hit with a hammer.

Abstract

The use of renewable energy as alternative energy is one of the alternative innovations that can be used to offset the need for energy consumption which is increasing every year. Efforts are made, starting with saving the use of petroleum as fuel and making innovations in creating alternative fuels that are easy to obtain, easy to process, and can reduce human dependence on petroleum as the main energy source. This is the basis for innovation in creating alternative fuels by analyzing the flame profile in diffusion combustion which is carried out experimentally using a widecell type HHO generator, 1.3 liters of water, stainless steel plates, a total of 8 plates, salt catalysts and variations in the addition of eucalyptus oil bioadditives (15ml and 30 ml). The results obtained, namely the largest flame profile with a flame area of 60,509 mm² with a temperature of 158.8 ℃ and the lowest flame profile with an area of 22,159 mm² with a temperature of 150.4 ℃. It is concluded that the more the addition of bioadditives, the greater the flame profile produced in diffusion combustion.

Abstract

The rapid growth has an impact on consumer demand for quality products, high quality and safe for consumption. In the production of cup packaged beverages after a series of product manufacturing processes are completed until they are released to the next process, bad seal leaking products are still found (poor sealing). Bad seal leaks are caused by a poor sealing process so that the product is not evenly sealed and results in packaging leakage considering that it can damage the quality and quality of the product. This research uses a real experimental method (True Experimental Research) using tensile testing with a Tensile Strenght Test tool. After conducting experiments on the appropriate settings to reduce the occurrence of bad seals in the filling machine sealing process, a parameter of 7 bar is set for each heater block, at the baket rotation speed setting after analyzing the parameter data carried out by the filling operator and QC line and conducting experiments, the appropriate parameter setting is obtained to reduce the occurrence of bad seal products, namely speed 5 (20 rpm) with a sealing process of 0.16 seconds, with the temperature that has been analyzed, a temperature of 200 ℃ is obtained as the appropriate standard temperature.

Abstract

One of the alternative energies that can be developed is hydrogen. To obtain hydrogen gas by decomposing air compounds (H2O) into hydrogen hydrogen oxygen gas (HHO) through electrolysis. considering the limited energy from the currently available mining materials is increasingly depleted. In order to overcome the above, one solution is to utilize the existence of alternative energy forms by utilizing electrical energy in the form of hydrogen gas stored in H2 which also comes from air (H2O) which can now be used for energy. Through this method, a catalyst is added to improve combustion efficiency in the HHO generator and after research, the addition of 14 grams of catalyst was able to increase energy as seen from the height of the flame 16 mm from the electrolysis process.

Abstract

The problem of poverty in fishing communities has become a cultural cycle. The issue has become a long causal chain of various aspects that is difficult to unravel over the years. The number of fishers is decreasing while the potential of marine resources has not been fully explored. It happens because poverty alleviation for fishing communities is only around 1% per year. The poverty alleviation program is closely related to the empowerment of fishing communities in running their businesses. So far, the fishing community's business problems have focused on weather/climate, infrastructure, technology (very little touched/used), and capital. However, not all fishing communities are not prosperous. There are different levels of exploration of marine potential in other areas. The Muncar fishing community is included in the successful category with Indonesia's second-largest business scale. The Muncar fisherman's business system, although applying the general Juragan-Worker method, has a traditional fishing method called Slerek, a boat system in pairs, one for fishing, the other providing accommodation. The Slerek system promises optimal catch. The catch-sharing system is 50:50 for the skipper and his group of workers. The Muncar fishing community business system can be adopted into an empowering marine worker business system after several modifications and adjustments have been made regarding the remaining problems.
