Optimization is one of the main keys to the success of the optimization process in CNC machines in the industrial field and provides information gain optimization control to improve product quality. Some benefits that can be obtained from optimization are speed and accuracy in product design and production processes. In the production process, a test of the desired quality is carried out. The international ISO rules machine tools especially, CNC milling machines using International Standard ISO 10791--7: 2014 Test condition for machining centres - Part 7: Accuracy of finished test pieces rules have concentricity of external circle under 25 &mgr;m. This maintenance case, use the method by increasing or decreasing the gain adjustment on the CNC milling machine input panel. This work was adjusting to find gain optimization settings using two methods, namely the Ballbar and the CMM measurement, to diagnose the CNC milling machine. Ballbar measurement to analyze the results of servo mismatch and circularity without trimming load, while CMM measurement to measurement through products produced on Fanuc CNC milling machine, the result is a trend of graphic error resulting in circularity error results. The best results on "Loop Gain Parameter - System V" which have circularity results on the Ballbar and CMM of 20 &mgr;m and 13 &mgr;m, it has circularity values below 25 &mgr;m at International Standard ISO 10791--7: 2014 Test condition for machining centres - Part 7: Accuracy of finished test pieces as a rule on CNC machines in the adjustment loop gain parameter.
优化是工业领域数控机床优化过程成功的关键之一,为提高产品质量提供信息增益优化控制。从优化中可以获得的一些好处是产品设计和生产过程的速度和准确性。在生产过程中,对所要求的质量进行测试。国际ISO使用国际标准ISO 10791—7:20 14对机床,特别是数控铣床进行了规定。加工中心的试验条件。第7部分:成品试样的精度。规定外圆同心度在25微米以下。本维修案例,采用在数控铣床输入面板上通过增减增益调节的方法。本工作是利用滚珠测量和三坐标测量两种方法对数控铣床进行诊断,以找到增益优化设置。球棒测量的结果是分析伺服错配和圆度不带修边载荷,而三坐标测量的结果是通过发那科数控铣床上生产的产品进行测量,结果是图形误差的趋势导致圆度误差的结果。在“回路增益参数-系统V”上的最佳结果是,在滚珠杆和三坐标测量机上的圆度结果为20 &mgr;m和13 &mgr;m,它的圆度值低于25 &mgr;m,符合国际标准ISO 10791- 7:20 14加工中心的测试条件-第7部分:成品测试件的精度作为数控机床在调整回路增益参数中的规则。

Study on The Potential Application of Water Hyacinth as An Organic Corrosion Inhibitor 水葫芦作为有机缓蚀剂的应用前景研究
Daniel Pradipta Juniardi, D. Widiputri, I. Kartawiria
Alloy and iron are examples of metals that commonly used as building materials and industrial purposes. Although they are strong materials, they are extremely corrosion prone. One of the methods for shielding metals from oxidation is the use of inhibitors. Although the synthetic corrosion inhibitors are highly efficient, due to their costs and dangerous environmental impacts, they cannot always be used for corrosion inhibition purposes. Therefore, in recent years, researchers based their works on green inhibitors of corrosion. This work was focused on the potential utilization of water hyacinth (WH) as a green corrosion inhibitor. The result of this work shows that the highest inhibition efficiency of WH extract is 65.3% in tap water and 47.1% in sodium chloride solution, when applied to SS400 metal. However, with the addition of an appropriate dose of gum Arabic (GA), the inhibition efficiency can be increased significantly. The highest inhibition efficiency of the WH and GA mixture is 71.08% in hydrochloric acid 32% solution after 3 days of immersion and 79.75% in sodium chloride 3.5% after 4 days of immersion.
合金和铁是通常用作建筑材料和工业用途的金属的例子。虽然它们是坚固的材料,但它们极易被腐蚀。保护金属不受氧化的方法之一是使用抑制剂。虽然合成缓蚀剂是高效的,但由于其成本和危险的环境影响,它们并不总是用于缓蚀目的。因此,近年来研究人员的工作主要集中在绿色缓蚀剂上。研究了水葫芦作为绿色缓蚀剂的应用前景。结果表明,水灵提取物对SS400金属的抑制率最高,在自来水中为65.3%,在氯化钠溶液中为47.1%。然而,加入适当剂量的阿拉伯胶(GA)可以显著提高抑制效率。在32%的盐酸溶液中浸泡3 d后,水杨酸与赤霉素的抑制率最高,为71.08%;在3.5%的氯化钠溶液中浸泡4 d后,水杨酸与赤杨酸的抑制率最高,为79.75%。

Elroy Fkp Tarigan, A. Syahriar, Y. Sutama
This study shows the simulation of thermostatic valve in the cooling system of Spark Ignition (SI) Engine and the behavior of warm up period for difference ambient temperature. There is a condition in the field if there is malfunction on thermostat the fastest solutions to do is to remove it. This study result shows that the simulation without thermostat have 3 time longer than a system with thermostat to reach the working temperature. If the time to reach the optimal temperature last longer, the combustion process becomes inefficient. The experimental data will be used to calculate new equation for difference ambient temperature and the result shows the recommendation to fix the cooling system with new thermostat rather than remove it.
本文对火花点火发动机冷却系统中的恒温阀进行了仿真,并对其在不同环境温度下的预热过程进行了仿真。现场有一种情况,如果恒温器出现故障,最快的解决办法就是将其拆除。研究结果表明,不带恒温器的模拟比带恒温器的模拟达到工作温度的时间长3倍。如果达到最佳温度的时间较长,燃烧过程就会变得低效。实验数据将用于计算新的环境温差方程,结果表明建议安装新的恒温器而不是拆除冷却系统。

Exploring Characteristic of Visual Management as Lean Toolbox in Construction Worksite of Apartment House 公寓建筑工地可视化管理作为精益工具箱的特点探讨
Yang Feng, Koichi Murata
At present, the construction industry is actively using lean production, which was born in the manufacturing industry, in order to improve the level of management and reduce wastes. This paper examines the implementation of visual management based on lean production in a construction site in Japan, and analyzes the use of visualization tools. It aims to solve two main problems: first, which visualization tools of lean production are used in Japanese construction industry? The second is that the author wants to clarify which practical problems these tools are used to solve, whether there is a one-to-one correspondence between the tools and the problem, or there is a phenomenon of overlapped purposes between them. To solve the above problems, the author makes a basic collection of the tools currently used in the construction industry by using methods such as on-site observation of the construction site in Japan, interviews with the managers and workers, and so on. Then he carries on word extraction and system diagram classification to the collected tools, which illustrates that the current visualization tools are used for five basic purposes, and at the same time clarifies the phenomenon that these tools do have overlapped purposes phenomenon. Last but not least, the author also analyzes these tools by using the co-occurrence network, and shows the details of the overlapped purpose phenomenon. These findings help to better understand the characteristics of construction site visual management tools from the perspective of the application of lean technology, laying a foundation for better utilization in the future.
目前,建筑行业正在积极采用诞生于制造业的精益生产,以提高管理水平,减少浪费。本文考察了基于精益生产的可视化管理在日本某建筑工地的实施情况,并分析了可视化工具的使用情况。它旨在解决两个主要问题:第一,日本建筑行业使用了哪些精益生产可视化工具?二是作者想要澄清这些工具是用来解决哪些实际问题的,这些工具与问题之间是否存在一一对应关系,或者它们之间是否存在目的重叠的现象。为了解决上述问题,作者通过对日本建筑工地的现场观察、对管理人员和工人的访谈等方法,对目前建筑行业使用的工具进行了基本的收集。然后他对收集到的工具进行了词语提取和系统图分类,说明了目前的可视化工具主要用于五个基本目的,同时澄清了这些工具确实存在目的重叠的现象。最后,作者还利用共现网络对这些工具进行了分析,并展示了重叠目的现象的细节。这些发现有助于从精益技术应用的角度更好地了解施工现场可视化管理工具的特点,为今后更好地利用这些工具奠定基础。

Op-Amp Based LC Oscillator with Minimum Components for Wireless Communications 基于运放的无线通信最小元件LC振荡器
D. Garinto, A. Syahriar, Harki Apri Yanto
This paper presents a new circuit of op-amp based LC oscillator design for wireless communications. This LC oscillator can be classified as a harmonic oscillator. Unlike Hartley, Colpitis and Clapp oscillators, the resonant tank circuit of the proposed op-amp based LC oscillator is composed of only two components --- single-inductor and single-capacitor, in parallel connection. Also, the LC oscillator does not use resistor components. The aim of this paper is to provide a low cost solution for sinusoidal oscillator design, particularly in low power mobile applications, where the power amplifier stage can be eliminated if the RF oscillator has enough output current and output voltage capabilities to supply the antenna load. On the other hand, the digital modulator is also integrated with the RF oscillator. The proposed op-amp based LC oscillator is analyzed and discussed using PSPICE simulation results. To verify the concept, experimental results are given. It can be observed that the simulation results are in line with the experimental results.
本文提出了一种基于运放的新型无线通信LC振荡器电路设计。这种LC振荡器可以归类为谐波振荡器。与Hartley, Colpitis和Clapp振荡器不同,所提出的基于运算放大器的LC振荡器的谐振槽电路仅由并联的单电感和单电容两个组件组成。此外,LC振荡器不使用电阻元件。本文的目的是为正弦振荡器设计提供一种低成本的解决方案,特别是在低功率移动应用中,如果射频振荡器具有足够的输出电流和输出电压能力来提供天线负载,则可以消除功率放大器级。另一方面,数字调制器也与射频振荡器集成在一起。利用PSPICE仿真结果对所提出的基于运放的LC振荡器进行了分析和讨论。为了验证这一概念,给出了实验结果。可以看出,仿真结果与实验结果吻合较好。

Antibiotic Inventory Policy Design for Minimizing Total Inventory Costs in Pharmacies based on ABC-Fuzzy Classification Analysis Approach using Probabilistic Continuous Review Method 基于abc -模糊分类分析法的药房抗生素库存策略设计——基于概率连续评审法
Naufaldanny Farhan Shiddieq, A. Ridwan, B. Santosa
PT XYZ is a company that providing the medication needs company employess. Problems that occur at the PT XYZ Pharmacies is the excess inventory in the pharmacy storage of PT XYZ Pharmacieswithout being balanced with customer requests that cause overstock. Ordering goods at the PT XYZ Pharmaciesis done every time there is a shortage of inventory, but the amount of antibiotics purchased at the ordering time does not have a standard that is standard so that there is an excess inventory of antibiotic category drugs. This research was conducted on the category of antibiotic drugs which have a total SKU of 1339 SKU and has a normally distributed demand pattern. Existing antibiotics at PT XYZ has not yet been classified, so it does not yet have priority handling, also caused an overbudget on company finances. The results of this study indicate that the classification of anitibiotics uses the ABC-Fuzzy Classification which is divided into three categories, namely very important with 142 SKU, important with 135 SKU, unimportant with 1062 SKU. The results of the calculation of total inventory costs using the probabilistic continuous review policy resulted in savings of Rp 59,840,285 or 24% lower than the total cost of existing inventory.
PT XYZ是一家提供药物的公司,需要公司雇员。在PT XYZ药房发生的问题是PT XYZ药房的药房存储中的库存过剩,而没有与导致库存过剩的客户请求平衡。每次库存短缺时,在PT XYZ Pharmaciesis订购货物,但订购时购买的抗生素数量没有标准,因此抗生素类药物的库存过剩。本研究以总SKU为1339 SKU且需求呈正态分布的抗生素类药物为研究对象。PT XYZ现有的抗生素还没有分类,所以还没有优先处理,也造成了公司财务超支。本研究结果表明,抗生素的分类采用ABC-Fuzzy分类法,分为非常重要(142个SKU)、重要(135个SKU)、不重要(1062个SKU)三类。使用概率连续审查政策计算总库存成本的结果导致节省Rp 59,840,285或比现有库存的总成本低24%。

Optimization on Malaria Computer Aided Diagnostic System 疟疾计算机辅助诊断系统的优化
Y. Wibisono, A. Nugroho, M. Galinium
Malaria is infectious tropical disease found in tropical countries, caused by unicellular protozoan parasite. Microscopic based diagnosis of malaria is conducted by manually examining a thin blood smear that is acquired from the infected patients. This method requires a trained human interaction and therefore it is time consuming and prone to errors. Computer Aided Diagnostics (CAD) for Malaria was developed to speed up the diagnosis and maintaining the accuracy. The experimental results showed that the system is able to recognize the infected red blood cells, the species and the life phase of the infecting Plasmodium. However, the average runtime of the detection using the original version is 41.45 seconds per image, which is too long if it will be used in the field. By measuring the runtime of each process in the program, optimization can be done by re-writing or substituting the algorithm that causes the longest runtime. Four modifications are proposed: Connected Component Labelling with Bounding Box, Contour Tracing Labelling without Inner Contour Extraction, Downscaled Clump Splitting, and Concave Point Based Clump Splitting. The experimental results showed that the system has an average runtime of 1.73 seconds while maintaining the same level of accuracy compared to the original one.
疟疾是一种在热带国家发现的传染性热带疾病,由单细胞原生动物寄生虫引起。疟疾的显微镜诊断是通过人工检查从感染患者身上获得的薄血涂片来进行的。这种方法需要训练有素的人工交互,因此耗时且容易出错。疟疾计算机辅助诊断(CAD)的发展是为了加快诊断速度和保持诊断的准确性。实验结果表明,该系统能够识别被感染的红细胞、感染疟原虫的种类和生命阶段。但是,使用原始版本进行检测的平均运行时间为每张图像41.45秒,如果在现场使用,这就太长了。通过测量程序中每个进程的运行时间,可以通过重写或替换导致最长运行时间的算法来进行优化。提出了四种改进方法:带边界框的连通分量标记、不含内轮廓提取的轮廓跟踪标记、降尺度聚类分割和凹点聚类分割。实验结果表明,该系统在保持与原系统相同精度的情况下,平均运行时间为1.73秒。

Analysis of Hotspot Data for Drought Clustering Using K-Means Algorithm 基于K-Means算法的干旱聚类热点数据分析
Ekki Rizki Ramadhan, E. Sutoyo, Ahmad Musnansyah, H. A. Belgaman
Drought is a disaster that is often experienced in Indonesia. This disaster occurred because Indonesia's geographical location is on the equator. Drought has had a major impact on the community such as crop failure, forest fires, soil damage, the emergence of disease outbreaks, and the extinction of animals and plants. Based on data from the Ministry of Environment of the Republic of Indonesia, the distribution of Riau's hotspots is quite unique. It is said so, because in this distribution, Riau has increased in every February and March as many as 277 and 248 hotspots in the last two years, namely between 2018 and 2019. To anticipate the drought that occurred in Riau, the clustering of drought-prone areas was conducted based on the analysis of hotspots data. This clustering of vulnerable areas is done by the K-Means algorithm. In determining the number of clusters of vulnerable areas, the elbow method is used as a determinant and produces as many as 4 cluster. The results of these method were analyzed by the silhouette coefficient. The result of analyzed is 0.388632163 and were classified as well-clustered. From these results, Rokan Hilir, Bengkalis, Kota Dumai are the dangerous district with 3106, 2361, and 117 point of dangerous distribution, respectively.
干旱是印尼经常发生的灾难。这场灾难的发生是因为印度尼西亚的地理位置在赤道上。干旱对社区产生了重大影响,如作物歉收、森林火灾、土壤破坏、疾病暴发的出现以及动植物的灭绝。根据印度尼西亚共和国环境部的数据,廖内省热点的分布非常独特。之所以这么说,是因为在这个分布中,廖内省在过去两年(即2018年至2019年)每年2月和3月都增加了277个和248个热点。为了预测廖内省发生的干旱,在热点数据分析的基础上对干旱易发地区进行了聚类。这种脆弱区域的聚类是通过K-Means算法完成的。在确定脆弱区域集群的数量时,使用肘法作为决定因素,并产生多达4个集群。用轮廓系数对这些方法的结果进行了分析。分析结果为0.388632163,归为聚类良好。从这些结果来看,罗坎希利尔、本卡利斯、哥打杜迈为危险区,分别有3106、2361和117个危险点。
