This study aims to determine the best bioethanol levels from a combination of cassava and pineapple peels mixture with variations of yeast mass as much as 11 grams, 13 grams, 15 grams and 72 hours fermentation time, to determine the optimal yeast mass and determine ethanol levels according to SNI. This research was carried out by hydrolysis using distilled water for 30 minutes, then fermentation using yeast and distillation process, then tested with a Refractometer Pen. Selected samples will be tested for ethanol content using the Gas Chromatography tool. The highest ethanol content of ethanol making with a combination of cassava and pineapple peels is for a combination of 75% cassava peel - 25% pineapple peel 88.6% in a 15 gram yeast mass, a combination of 50% cassava peel - 50% pineapple peel 89.3% in 15 gram yeast mass. So it can be concluded that the ethanol content of the combination of cassava and pineapple peels is not included in the category of Indonesian national standards (SNI).

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.
HHO气体是一种可以替代化石能源的替代能源。HHO气体本身有几种生产方法,其中一种是利用水电解。水被赋予直接电荷,因此水分子(H2O)分裂成HHO气体。本研究的目的是确定铁板电极距离从2mm, 4mm和6mm变化对HHO发生器的生产率和效率的影响,因为使用的水是与KOH溶解在一起的Teluk Tamiang村的海水。从实验中得到的数据以电压、电流、产生50ml HHO气体的时间、海水的pH值、电解前后溶液的pH值、电解后的温度等形式进行。然后对数据进行处理,使其在2毫米距离处的生产率最高,平均流速为0.89 ml/s,在2毫米距离处的效率最高,平均为23.83%。这是因为在2毫米的距离上,电子从阴极电极移动到阳极电极的速度更快,产生的电阻更小,因此HHO发生器产生更快的氢氧气泡,更少的功率和能量消耗。

 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%.
型煤是一种令人满意的替代化石燃料的能源,其可用性日益减少。型煤的主要材料可以是生物质。生物质是通过光合作用产生的有机物质,这些物质可以是产物、残余物或废物。玉米棒子是一种潜在的巨大生物质,可作为蜂窝煤的主要成分。本研究的目的是(1)了解粘附菠萝蜜籽粉的玉米芯型煤的特性,包括含水率、灰分、挥发物和热值;(2)了解基于SNI标准的最佳玉米芯型煤的特性。采用炭化工艺将玉米芯转化为木炭,然后将木炭与菠萝蜜籽粉制成的粘合剂混合。在本研究中,玉米芯与菠萝蜜种子比例的变异分别为90%:10%、85%:15%和80%:20%。然后用100 kg/cm2和120 kg/cm2的模压变化对木炭和面粉的混合物进行模压。基于SNI 01-6235-2000的型煤特性参数为含水率、灰分、挥发物和热值。结果表明,炭与菠萝蜜粉比为90% ~ 10%、印刷压力为120 kg/cm2、样品代码为B1的型煤性能最佳。该型煤含水量为70073%,灰分含量为6,8876%,挥发物含量为17,8983%,发热量为6241,8137 cal/g。但总的来说,这些型煤没有达到SNI 01-6235-2000标准,因为型煤中挥发物的含量超过了已确定的最大限量,即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.
回收是一种处理废旧材料的方式,从选择、收集开始,然后是铸造过程,以创造更有价值、更经济的新产品。本研究的目的是了解以闸瓦和盘为导向材料的AI合金渣铸造温度对气孔率、硬度、显微组织(蒸发铸造结果)的影响。废旧铝的回收利用是减少铝废料的一种替代方法。铸造温度是一个可以影响铸造结果的变量,如果铸造温度低,那么在模具完全填充之前就会快速冻结。如果浇注温度过高,则会发生收缩,孔隙率值可能会增加。本研究使用了四种铸造温度变化,即:650°C, 700°C, 750°C和800°C。蒸发铸造法采用聚苯乙烯泡沫塑料的模式,堆积在砂型。被铸造的金属会形成类似泡沫塑料的图案。铸造温度测试的结果会影响气孔率、硬度和显微组织。
