Aluminum waste that has accumulated due to the widespread use of aluminum in household needs, daily life, and in the manufacture of industrial material components will have an impact on the environment if not handled properly. It is necessary to utilize aluminum waste in a product that has a sale value through a casting process using a crucible furnace. This research was conducted to determine the hardness differences of waste aluminum from used aluminum cans, used aluminum pots, and used aluminum wires melted in a smelting furnace. This study uses quantitative analysis and experimental research types. Tests carried out on this crucible furnace were carried out to determine the effect of the type of aluminum waste and the length of time it took to smelt the three types of material on the hardness results. The results of the Rockwell hardness test on aluminum can waste have an average value of 71.38 HRB, on aluminum pans waste it has an average value of 71.68 HRB, and on aluminum cable waste it has an average value of 53.02 HRB.  
由于铝在家庭需求、日常生活以及工业材料部件制造中的广泛使用而积累的铝废物,如果处理不当,将对环境产生影响。有必要通过坩埚炉铸造工艺,将废铝利用在有销售价值的产品中。本研究测定了废铝罐、废铝罐和废铝丝在熔炼炉中熔化后的废铝的硬度差异。本研究采用定量分析和实验研究两种研究方式。在这个坩埚炉上进行了试验,以确定铝废料的类型和熔炼三种材料所需时间的长短对硬度结果的影响。铝罐废料的洛氏硬度测试结果平均为71.38 HRB,铝锅废料的洛氏硬度测试结果平均为71.68 HRB,铝电缆废料的洛氏硬度测试结果平均为53.02 HRB。

Solar panel systems are widely used to meet energy needs at this time. Solar panels have optimal power for 4 hours, namely 10:00 to 14:00. but this is still said to be not optimal if the angle of the static solar panels does not follow the movement of the sun. This can also be caused by weather factors that are covered in clouds. Previous research conducted by Tri Wahyu Ardianto used mirror reflectors but was not equipped with sensors and data storage. Based on this, to optimize solar panel energy, a flat mirror reflector design for solar panels has been made, equipped with four flat mirror reflectors on each side to form a large square. The solar panel is placed in the middle between the four flat mirrors. In this study, the measurement of electric power was carried out by carrying 3 variable angles for reflector positions, namely 0°, 60°, and 70°. The decision of the three reflector positions is made to find out the ratio of the maximum output power values. This system is also equipped with current, voltage, and light intensity sensors. The results show that the maximum output power of solar panels is shown at the reflector position of 60° with an average power output of 19.70 Watt followed by a reflector position of 70° with an average output power of 19.18 Watt and finally the reflector position is 0° with an average output power value of 14.87 Watt.
太阳能电池板系统被广泛用于满足此时的能源需求。太阳能电池板的最佳功率为4小时,即10:00至14:00。但如果静态太阳能电池板的角度不跟随太阳的运动,这仍然被认为不是最佳的。这也可能是由云层覆盖的天气因素造成的。Tri-Wahyu Ardianto之前进行的研究使用了反光镜,但没有配备传感器和数据存储。基于此,为了优化太阳能电池板的能量,对太阳能电池板进行了平面反射镜设计,每侧配备四个平面反射镜,形成一个大正方形。太阳能电池板被放置在四个平面反射镜之间的中间。在本研究中,通过对反射器位置进行3个可变角度的测量,即0°、60°和70°。决定三个反射器位置是为了找出最大输出功率值的比值。该系统还配备了电流、电压和光强传感器。结果表明,太阳能电池板的最大输出功率显示在60°的反射器位置,平均功率输出为19.70瓦,然后是70°的反射器,平均输出功率为19.18瓦,最后反射器位置为0°,平均输出功率值为14.87瓦。

A series of processes are carried out in order to obtain the desired product result. One of the processes carried out is testing the strength of polymers by means of tensile testing in this case testing of polymer-based sealants. The method used is the method of simulating frame loading on the tensile testing machine that has been made. The software used to assist the simulation process is SolidWorks. The simulation is carried out in static mode or a fixed loading (no movement or vibration). A stress Analysis Simulation is carried out to get the result of static loading in the form of σ (stress). Loading simulations on the frame of the tensile testing machine for the tensile testing of the sealant are carried out on the components of the frame with different loading variations. Frame components with upward loading are given an average load of 38.5 MPa. Meanwhile, the frame components with downward loading are given an average load of 6.169 MPa. The largest average stress obtained from each component is 0.326 N/mm2. this value does not exceed the yield strength of  235 N/mm2.

Indonesia is an agricultural country with 40% of the population's livelihood provided by farmers. Harvested rice typically has a moisture content of 20-27% on a wet basis. The type of artificial dryer that is often used is the tub or rotary type. This research aims to develop a rice dryer using a combined tray and rotary-type method. Based on the result, the higher the speed dryer, the shorter the drying time. The net result of this test is that the relationship between time and engine speed is inversely proportional. The higher the speed, the shorter the drying time. The net result of this test is that the relationship between time and engine speed is inversely proportional. Rice drying results can be described as dry, but not including ready-to-eat rice standards. The higher the speed, the shorter the drying time.

Backward-facing step (BFS) is a model that provides several applicative features in engineering. The complex phenomena of BFS flow have a crucial impact on any application. Therefore, this study comprehensively investigates the flow characteristics of BFS with various step shapes. The backward-facing step (F-BFS) fillets were tested at intervals of Reynolds number 50 smaller than Re smaller than 400 using the CFD approach. Based on the computational results, it was found that flow separation is a fundamental phenomenon in BFS flow. Due to sudden expansion, Flow separation forms a recirculation area which continues to increase almost linearly with an increase in the Reynolds number. The recirculation area contains unstable rotating vortexes, which can impact the flow efficiency of BFS. Using a different step shape proves that F-BFS can minimize the recirculation area to increase the efficiency of the BFS flow.  
后向步进(BFS)是一种具有多种工程应用特征的模型。BFS流动的复杂现象对任何应用都有至关重要的影响。因此,本研究对不同阶跃形状的BFS流动特性进行了全面的研究。采用CFD方法,在雷诺数为50 < Re < 400的区间内对后向台阶(F-BFS)圆角进行了测试。计算结果表明,流动分离是BFS流动中的一个基本现象。由于突然膨胀,流动分离形成了一个再循环面积,该面积随着雷诺数的增加几乎呈线性增加。再循环区存在不稳定的旋转涡,会影响BFS的流动效率。采用不同的阶跃形状证明了F-BFS可以最小化再循环面积,从而提高BFS流的效率。

As the solidification reaches the hot spot area, no molten metal remains and shrinkage is formed. To anticipate the shrinkage, a riser is added to the casting system. An optimal riser design would produce free shrinkage components. One of the factors that affect riser efficiency is the riser shape. This study aims to find the most efficient side riser shape by using simulation software. The riser shape of tubes, tubes with a half sphere on top, hemispheres, conical tubes, tubes with an oval cross-section, and cubes are used in this experiment, with the volume of all risers kept constant. The most efficient shape of the riser is the tube. The tube riser produces a larger modulus. The tube riser generated directional solidification. The same pattern can be seen in the niyama criteria and solidification temperature, where the tube riser has a more continuous pattern compared to other riser shapes.

The communication between microcontrollers and PLC has become an important technology development that needs to be enhanced. One of the reasons for the communication between these two devices is to facilitate the input process of data or information from sensors, which are responsible for detecting or measuring specific parameters. Not all sensors can be directly read by PLC, as some sensors have their own communication protocols or specific libraries that are not directly supported by PLC. Microcontrollers are often used as intermediaries between sensors and PLC. Microcontrollers can read sensor data and then convert it into a format that can be understood by PLC. Microcontrollers can perform flat processing tasks such as conversion and status evaluation to provide more relevant data, and then send this data to the PLC through a compatible communication protocol. In this study, the communication protocol used is the Host Link serial communication using the C-mode Command method. The communication testing conducted using 10 different data samples resulted in accurate values with an error percentage of 0%.
微控制器与PLC之间的通信已成为一项需要加强的重要技术发展。这两个设备之间进行通信的原因之一是促进来自传感器的数据或信息的输入过程,传感器负责检测或测量特定参数。并非所有传感器都可以由PLC直接读取,因为一些传感器有自己的通信协议或特定的库,而PLC不直接支持这些协议或库。微控制器经常被用作传感器和PLC之间的中介。微控制器可以读取传感器数据,然后将其转换为PLC可以理解的格式。微控制器可以执行转换和状态评估等平面处理任务,以提供更多相关数据,然后通过兼容的通信协议将这些数据发送到PLC。在本研究中,使用的通信协议是使用C模式命令方法的Host Link串行通信。使用10个不同的数据样本进行的通信测试得出了准确的值,误差百分比为0%。

Hot rolled plate steel as a material to be used for steel armor needs to have the characteristics of a high hardness value. Medium carbon steel as the basic material is quenched at a temperature of 900 oC and tempering is carried out at a temperature of 125 oC and 175 oC with a holding time of 30 minutes. The Ms value is a benchmark for changes in martensite which is influenced by the constituent elements of the material. The use of water as a quench medium changes the structure of austenite to martensite. The martensite structure that occurs increases the optimum hardness value in HRP Steel material. The tempering process carried out above the Ms value causes a decrease in the hardness value. The highest hardness value was obtained in the quenching process with 542 HV which was influenced by the distribution of martensite. The decrease in hardness value occurs due to the tempering process, the average hardness value at temper 125 oC is 524.4 HV and 175 oC is 524 HV.
热轧钢板作为钢板装甲的材料,需要具有高硬度值的特点。中碳钢作为基本材料,淬火温度为900℃,回火温度为125℃和175℃,保温时间为30分钟。Ms值是马氏体变化的基准,马氏体变化受材料组成元素的影响。水作为淬火介质使奥氏体的组织转变为马氏体。产生的马氏体组织提高了HRP钢材料的最佳硬度值。在Ms值以上进行回火处理会导致硬度值下降。在542 HV淬火时硬度值最高,这与马氏体的分布有关。回火处理导致硬度值下降,回火125℃时的平均硬度值为524.4 HV, 175℃时的平均硬度值为524 HV。

The highest hardness value was obtained in the quenching process with 542 HV which was influenced by the distribution of martensite. The decrease in hardness value occurs due to the tempering process, the average hardness value at temper 125 oC is 524.4 HV and 175 oC is 524 HV.","PeriodicalId":33598,"journal":{"name":"Infotekmesin Media Komunikasi Ilmiah Politeknik Cilacap","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48355105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The increase in the volume of vehicles resulted in a crisis of fossil fuels so there is a need for alternative fuels to replace gasoline. Butanol and Diethyl Ether (DEE) are alternative fuels that can be added to gasoline. This is because the Octane Number and high O2 levels optimize combustion in the cylinder and increase torque and power and save fuel. This study compares the addition of butanol and DEE to gasoline on torque, power, and Brake Specific Fuel Consumption (BSFC). The study used a 160cc gasoline engine with a carburetor with engine speeds of 1000, 2000, and 3000 rpm. Variation of fuel mixture 5%, 10%, and 15% on gasoline. The results showed that the DEE15 mixture increased the highest torque by 28% at 3000 rpm compared to other fuel mixtures. Engine power also increases the highest by 28% when using a mixture of DEE15 compared to other fuels. Meanwhile, BSFC experienced the highest decrease of 19% when using the DEE15 mixture compared to other mixtures.
汽车数量的增加导致了化石燃料的危机,因此需要替代燃料来代替汽油。丁醇和二乙醚(DEE)是可以添加到汽油中的替代燃料。这是因为辛烷值和高O2水平优化了气缸中的燃烧,增加了扭矩和功率并节省了燃料。本研究比较了在汽油中添加丁醇和避蚊胺对扭矩、功率和制动比油耗的影响。这项研究使用了一台160cc汽油发动机,发动机转速分别为1000、2000和3000转/分。汽油混合气的变化率分别为5%、10%和15%。结果表明,与其他燃料混合物相比,DEE15混合物在3000rpm时的最高扭矩增加了28%。与其他燃料相比,当使用DEE15的混合物时,发动机功率也最高增加了28%。同时,与其他混合物相比,当使用DEE15混合物时,BSFC经历了19%的最高下降。

This study aims to test the performance of the Batam Marine Ambulance model as a medical and logistics support fleet using the comparison ship method. A series of stability and motion analysis processes were carried out, then the results were assessed to determine the best design among the proposed design options. Performance tests used three ship models (Model I, Model II, and Model III). It is known that in the stability test, the tilt angle of model III is 33.63° and the maximum GZ value is 4.673 cm. Then, in the resistance test, Model I has a lower resistance of 87.29 N and the required power is 1496.93 W compared to the other proposed models. In the seakeeping test, Model III was found to be more stable or less affected on all surface conditions because the RAO value was relatively lower, namely 90o in terms of heaving, rolling, and pitching at 135o and 180o then had lower additional resistance. The Model III design has good ship stability, drag, and seakeeping characteristics.
本研究旨在使用比较船方法测试巴淡岛海上救护车模型作为医疗和后勤保障船队的性能。进行了一系列稳定性和运动分析过程,然后对结果进行评估,以确定所提出的设计方案中的最佳设计。性能测试使用了三个船舶模型(模型一、模型二和模型三)。已知在稳定性测试中,模型III的倾角为33.63°,最大GZ值为4.673 cm。然后,在电阻测试中,与其他提出的模型相比,模型I的电阻较低,为87.29 N,所需功率为1496.93 W。在耐波性试验中,发现III型在所有表面条件下都更稳定或受影响较小,因为RAO值相对较低,即在135°和180°的起伏、滚动和俯仰方面为90°,然后具有较低的附加阻力。Model III设计具有良好的船舶稳定性、阻力和耐波性。
