HHO gas is an alternative energy that can replace fossil energy sources. HHO gas itself can be produced in several ways, one of which uses water electrolysis. Water is given a direct electric charge so that the water molecule (H2O) splits into HHO gas. This study aims to determine the effect of iron plate electrode distance on the productivity and efficiency of HHO generator by varying it from 2 mm, 4 mm and 6 mm, for the water used is the sea water of Teluk Tamiang Village which was dissolved together with KOH of 3,04%. From the experiments carried out the data obtained in the form of voltage, current, time to produce 50 ml of HHO gas, pH of sea water, pH of the solution before and after electrolysis, and temperature after electrolysis. The data is then processed so that it gets the highest productivity at a distance of 2 mm with an average flow rate of 0,89 ml/s and the highest efficiency at a distance of 2 mm with an average of 23,83%. This is because at a distance of 2 mm the electrons move from the cathode electrode to the anode electrode faster and the resulting resistance is smaller, so that the HHO generator produces faster oxyhydrogen bubbles and less power and energy consumption.

In the present era of technological developments in the industrial world is growing and progressing. But in the industrial world can not be separated from the manufacturing process, especially in the field of welding, because welding has an important role in engineering or reparasi-raparasi associated with metal welding. And also a lot of welding is used in the field of design. The scope of welding use in construction is very wide including shipping industry, bridge, steel frame, heavy equipment, transportation facilities, pipeline and so forth. In the process of welding requires a person who is reliable or skilled in welding work, in order to produce good quality results. The highest value of bending stress is found on air cooling medium that is 2870,17 N/mm², And the lowest bending voltage value is in water cooling that is 2460,1 N/mm².. The highest shear stress value is in air cooling medium ie 197.96 N/mm², and the lowest shear stress value is in water cooling that is 169.68 N/mm². The bending voltage value allowed is the highest in the air conditioning medium 2474.5 N/mm², And the lowest permissible bending stress value is found in water cooling of 2121 N/mm².

Briquette is one of the alternative energy sources as a satisfactory substitute for fossil fuels in which the availability decreases every single day. The main materials of briquettes can be biomass. Biomass is an organic material produced by photosynthetic process, the materials may be product, remnant or waste. One of the potentially great biomass to be used as the main ingredient of briquettes is corncob. This study aims to (1) know the characteristics of corncob briquettes with adhesive jackfruit seed flour including moisture content, ash content, volatile matter and calorific value, (2) know the characteristics of the best corncob briquettes based on SNI standard. Corn cobs were converted first to charcoal with carbonization process, and then the charcoal was mixed with adhesive derived from jackfruit seed flour. In this study, variations of corncob to jackfruit seeds ratios were 90%: 10%, 85%: 15% and 80%: 20%, respectively. Then a mixture of charcoal and flour was molded with a molding pressure variation of 100 kg/cm2 and 120 kg/cm2. The parameters of briquette characteristics based on SNI 01-6235-2000 are moisture content, ash content, volatile matter and calorific value. The results show that the best characteristic briquettes is briquettes with sample code of B1 with charcoal to jackfruit flour ratio of 90% to 10% and printing pressure of 120 kg/cm2. The briquettes have water content characteristics of 7,0073%, ash content of 6,8876%, volatile matter of 17,8983% and calorific value of 6241,8137 cal/gram. But overall, the briquettes have not met the SNI 01-6235-2000 standards because the level of volatile matter in the briquettes exceed the maximum limit that has been determined i.e. 15%.

Recycling is a way of processing used materials that is started with selection, collection, then the process of foundry to create a new product that is more valuable economical. The objective of this research is to know the effect of casting temperature with the kind of guide material AI alloy junk from brake shoe and pan on porosity, hardness, microstructure (the evaporative foundry result). The recycling of used aluminum is an alternative to reduce the waste material from aluminum. Casting temperature is an variable that can effect the result of foundry where if the casting temperature is low, then there will be a quick freeze before the mold is completely filled. And if the casting temperature is too high, then shrinkage can occur and the porosity value may increase. This research used four casting temperature variations, namely: 650°C, 700°C, 750°C, and 800°C. The evaporative foundry method uses styrofoam pattern that is piled up into sand mold. The metal that is casted will form like styrofoam pattern. The result of casting temperature testing can effect on porosity, hardness, and microstructure.
